Project Understanding and Approach (Maximum Points 30) 4. Describe the prime Consultant’s methodology and detailed scope to the project. Include how the prime Consultant will use subconsultants in the project. Provide strategy for updating the MIKE SHE/MIKE 11, in accordance with the outcomes of community stakeholder meetings, recent modeling efforts and refined drainage and control structures data available, projected land use changes,

AECOM will review the latest FEMA MIKE SHE/MIKE 11 model and associated GIS geodatabase, as applicable. The current model is referenced to NAVD88 elevation datum that includes the 2009 LiDAR data sets, and was updated to include surveyed cross sections of canals C-11, C-13, C-14, C-42 and North New River. In addition to the information obtained through the Stakeholder Meetings, a watershed evaluation will be conducted to review the watershed boundary, the hydrologic and hydraulic features, tidal boundary conditions, documentation of the flooding problems within the watershed, and to identify land use changes since the model was last developed, potential survey needs, and other data required to complete the updates to the watershed model. All model maintenance activities will be performed in accordance with Broward County stormwater manual and SFWMD stormwater rules and regulations. A more detailed description of specific tasks follows.

The DHI Team will perform a review of existing models, reports, and data sources for relevant information that may impact model and scenario development. Studies, reports and guidance from partner municipalities on future conditions relevant to the study will also be assimilated. This information will include sources identified in the initial stakeholder meetings and subsequent follow up and communication activities. Our proposed strategy for this assessment will include the following three stages. Stage 1: DHI will review and assess the existing model as applied for the FEMA flood mapping and provided a detailed summary of the approach, method and any likely issues that may arise in the application to the current scope of work. Stage 2: DHI and the project team will assess the relevant existing conditions changes from the current model representation. This may include information that was not available at the time of the model, or changes that may have occurred in the ensuing period. This analysis will

Our approach to the MIKE SHE/MIKE 11 modeling of potential future conditions involves executing a scientifically defensible set of procedures, carefully formulated to predict the extents and severity of future flooding in response to future changes in land use, sea level, and extreme rainfall. The Team’s approach will be similar to procedures that the Team has employed on other MIKE SHE/MIKE 11 modeling projects in Florida including the recent Big Cypress Basin (BCB) Flood Protection Level of Service (LOS) Project for the South Florida Water Management District. As with any modeling project we undertake, we’ll be well prepared to present the modeling process, assumptions, and results to stakeholders at a number of important milestones. We understand the importance of describing the model in a way that makes it comprehensible to “non-modelers”, and we pride ourselves on our ability to do so effectively. Updates to the Existing Condition

The Higgins Engineering Team's approach to engineering design, analysis and coordination is primarily driven by our ability to coordinate with key internal and external staff.

We are committed to providing the County with a team of highly skilled engineers, some with many years of past experience as water management agency employees and consultants.

As a small company, LAGO uses a management style that is based on collegiality and full buy in of every person in the firm. Informal discussions at the beginning of each day ensures that the technical challenges are properly addressed and that the work proceeds in a streamlined fashion with no overlap on specific tasks. As the prime consultant, LAGO will extend this collegial style to include team members from Bermello Ajamil, Ross Engineering, and CRS Max. LAGO will carefully review deliverables to ensure that they are accurate and consistent with the needs of the project. A key element of this project will be associated with Quality Assurance/Quality Control, which will be conducted by the Ananta Nath, P.E. and Maria Bravo, P.E. During the process of updating the model, the input data and results will be thoroughly reviewed and questioned by geologic and surface water experts. Predicted flow and stage results will be thoroughly reviewed to verify




future groundwater elevations and updated tidal downstream boundary conditions. Describe the prime Consultant’s plan to evaluate potential CRS creditable criteria resulting from this project and propose recommendations to the involved communities. (15)

To perform the model update and maintenance on the MIKE SHE/MIKE 11 model, all sources of relevant data must be collected. AECOM will collect and review the relevant available information of existing structures from both regulatory and non-regulatory databases, which includes, but is not limited to, a review of: � Existing model � Existing GIS databases � Previous hydrologic/hydraulic reports (i.e. Coastal Studies, Groundwater level projections, Stormwater Master Plans for Fort Lauderdale and other municipalities and/or drainage districts.) � Environmental Resource Permit (ERP) files and as-built information of projects through Stakeholder Meetings � DBHYDRO and other sources of gage data (stages and flows) � SFWMD files (tidal boundary files) or other tidal level predictions/projections. � Topographic information (updated LiDAR) � FEMA Coastal Zone A re-modeling and associated reports. After review of existing information and after collecting information from stakeholders, AECOM will carry out a field reconnaissance of the project sites to confirm the existence or nonexistence of hydraulic features represented in the model, understanding of the drainage patterns, identify potential data conflicts between the model and data review, and compile a field inventory of the existing structures using the most innovative approaches such as GPS, GPRs, and GIS as applicable. Assignments in this task may also include investigation of areas where existing topographic data may be inconsistent with aerial photography or might not seem appropriate based on available as-built data/LiDAR. Based on the review of existing information and hydraulic features verification in the Field

be based on the information obtained in the stakeholder meetings, and a review of the data and models available from the stakeholder and communities. Stage 3: Future Conditions Assessment. A review and summary will be provided on the anticipated future conditions, including: landcover and landuse, drainage and control structure modifications and operations, coastal interactions and related changes to infrastructure. A matrix report will be developed comparing the models and recent developments (after FEMA 2014 FIS and ongoing Coastal Zone Remapping) and existing and future conditions data sources, allow with an estimate of the relative importance of these changes to the outcome of the current study, including those which are critical to the development of an accurate and coherent flood elevation map for future conditions. This information will form the basis of the subsequent tasks. Using information developed in earlier tasks, the DHI Team will incorporate the critical updates as reported in in Task 2. A systematic model update will be achieved in the following manner, in accordance with FEMA Guidelines and Standards. Existing Conditions Model Updates. The information used for the model update will include the information identified in the RFP, including recent modeling efforts, drainage systems updates and control structures data, revised cross section for the main canals affected by sedimentation or significant maintenance, and landcover and land use changes occurring since the FEMA FIS effective model development. Following these revisions, an assessment of the calibration will be provided. If necessary and supported by the available data, a recalibration will be performed to ensure that the model

Model Identified through Community Stakeholder Meetings and Recent Modeling Efforts As part of the Team’s modeling efforts on the BCB LOS project, we started with a previous BCB MIKE SHE/MIKE 11 model prepared by others and undertook a thorough review. We relied on our previous experience in both preparing and peer-reviewing MIKE SHE/MIKE 11 models, and on field observations and input received from local stakeholders, to identify numerous additions and modifications to the model. By implementing these changes, we were able to demonstrably improve the model’s ability to predict peak stages and flows in response to extreme rainfall events. Similarly, one of the first tasks in the Broward County model update will be to meet with community stakeholders, including local municipalities and others, to identify and prioritize potential changes to the “current conditions” MIKE SHE/MIKE 11 model. These may include updates to drainage systems, control structures, and sedimentation information based on stakeholder input on recent observations and/or recent local-scale modeling efforts including the City of Fort Lauderdale Stormwater Master Plan. These changes will be made in parallel with any changes that may be required based on our initial review of the 2014 FEMA model to minimize impacts to the schedule. Preliminarily identified potential model updates include updated tidal information for downstream boundary conditions developed by the South Florida Water Management District (SFWMD) and incorporation of recent land use changes and refined LiDAR information. It is anticipated that desktop and field data collection efforts may be necessary to address

Our approach will focus on the key tasks outlined in the RFB Scope of Work. This type of project is not new to our team as we have many FEMA and flood modeling projects in the past. Since certain members ·of our team are MIKE SHE/MIKE 11 experts they will be focused on the items which involve the optimum utilization of the model's current capabilities and identify ways that linkages between the model and new program utilities can speed up flood mapping updates in the future . Other team members are experts at the water management system, their capacities and past and future plans for modification, such as the near future construction of the C-11 and C-9 impoundment projects. Other team members will apply their efforts on identifying CRS opportunities of future changes. It is our belief that a lot of extremely valuable and timely input from both the stakeholders meetings and the use of a peer-review panel of experts to examine each major decision along the way, at approximately monthly meetings. When our team performed a similar exercise for a 174 square mile urban area in Palm beach County, a panel of local experts reviewed every decision and assumption by the team at routine intervals and what we found was unanimous acceptance of the project outcomes in the end.

that the results are reasonable and consistent with the latest and most defensible data available. Key model Inputs: Elevation Data: LAGO has completed a topographic data comparison analysis to evaluate the difference between the model elevation data and the most recent digital elevation model (DEM) available from the SFWMD. In this figure (see page 45) positive values indicate that the elevation in the new data is lower than what is in the existing model. Thus, it is possible that the updated model will predict greater inundation in some parts of the county. Land Use Data: LAGO also reviewed the land use data in the model. In general, the county is mostly built out, so representation of existing infrastructure becomes increasingly important. During our review, we noted that some of the lakes and other water storage features associated with development were not explicitly represented in the MIKE SHE model. Adding these features would likely improve the predicted timing and volume of flow discharged to the primary drainage network. Structures: Lago has reached out and partnered with individuals that have a thorough knowledge of the stormwater systems in Broward County. Jose Lopez, P.E. is a member of the Technical Advisory Committee and he will serve as a liaison with the SFWMD, water control districts, City of Fort Lauderdale and other municipalities on recent modeling efforts, tidal information, expected land use revisions, and potential future modifications to existing infrastructure to be incorporated into the model, as applicable. Ross Engineering has been involved in the design and construction of several of the stormwater management features in Broward County.




Reconnaissance Task, AECOM will develop a survey plan in GIS format (if necessary) that identifies hydraulic features in the watershed for which hydraulic parameters are required and locations of missing/ inconsistent topographic data. The plan will include those features to be explicitly modeled, but where viable elevation data is not readily available. The plan will also include evaluation of sediment depths in the main channels. This survey plan will be submitted to Broward County for approval before being executed. After the identification of the survey needs, and if approved by Broward County, the AECOM Team will proceed to perform the required survey. For this purpose, we have included Whidden Survey and Mapping (WSM) in our team. WSM is a surveyor firm with ample experience in hydrographic evaluations and surveys. Having WSM in our team will expedite and facilitate the coordination of any field work if required. Using the above information, the MIKE SHE portion of the model will include the updates to the hydrologic and hydraulic datasets as described in the following sections below: Rainfall / Evapotranspiration (see below – next criteria) The LiDAR dataset in the existing model will be updated as required with the new LiDAR dataset if available per the Data Collection and Review Task. In addition, if any topographic survey is performed under the Identification of Survey Needs Task; it will be incorporated in to LiDAR as well to create a fully functional topography file. Quality check will also be performed by comparing the Sub-basin stage-storage computed using the high-resolution LiDAR and fully functional model topography file. The check is done to see if there is significant

is appropriate for representing the current conditions with respect to modeling the flood events. Future Conditions Model Updates for Scenario Development. The development of an updated exiting conditions and base model for future conditions requires a methodology for describing the interactions of the coastal model and the inland flood model. A range of alternatives are available, from the most simplistic assumptions, to quite complex alternatives that allow for resolving the interactions between the coastal zone and inland regions subject to primarily pluvial and groundwater based inundation, and drainage impacts due to coastal conditions. In reality, these domains are part of a single continuum, but due to modeling practices, regulatory approaches and practical limitations, these elements are often divided into separate analyses, with some loss of fidelity in managing their interaction. Coastal Integration and Modeling Approach FEMA is currently in the process of updating coastal flood maps for Broward County as part of their RiskMAP program. However, per FEMA’s mandate, these updates do not currently consider future conditions. The integration of inland and coastal flooding for FEMA are currently performed as separate exercises, using a combined probability assessment to process final flood risk zones and elevations in the region. The coastal flooding component in South Florida utilizes two different methods to determine annualchance stillwater elevations. � High frequency methods using a regional tide-gauge statistical assessment (10-percentannual- chance condition) � Low-frequency methods using a synthetic hurricane set developed using the Joint Probability Method – Optimal Sampling (Quadrature) methods (2-

model update/ refinement needs identified by community stakeholders and the Geosyntec team. These efforts may include targeted collection and review of plans and as-built data from permits and municipal records, field reconnaissance to confirm drainage infrastructure, and topographic survey by subconsultant Stoner & Associates, Inc. Once all model updates and refinements are complete, the updated model will be run for the 10-, 25-, 50- 100-, and 500-year storm events using current rainfall depth / distributions. The model results will be used a baseline for comparison to the future conditions model scenarios. Calibration data will be used to refine model input parameters based on available data. Future Conditions Model Scenarios Development Model Updates for Projected Land Use Changes - Although Broward County is largely built out, future land use changes may result in localized changes to drainage patterns and runoff volumes, especially if increases in the intensity of development are considered. For this reason, we propose to obtain and review future land use mapping prepared by the County and/or SFWMD to identify significant areas slated for development, and existing sparsely developed areas slated for redevelopment to more intense land uses. In these areas we propose to update the following MIKE SHE parameters: � Topography (raise if needed based on FEMA BFE) � Paved area runoff coefficient (to reflect directly connected impervious area) � Drain depth and drain time constant (to represent small-scale urban and agricultural drainage features) � Depression storage. For larger areas to be developed, we may also model

Drainage: The drainage parameter is defined by the software user and determines how and where a portion of the runoff drains from the landscape. LAGO developed a tool that is not available in the MIKE SHE software package that produces a visual map that indicates the discharge location of each cell in the model where drainage is specified. Our review of the drainage component indicated that some areas of the model are not routed correctly. Detailed approach per task LAGO has considered this project in detail and offers the following approach to complete the tasks specified in the Scope of Work: Task 1. Participation in three (3) community stakeholder meetings (with related follow-up if necessary). For this task, LAGO considers it imperative to have a task leader that is intimately familiar with the municipalities and water supply organizations in Broward County. Therefore, we have asked Jose Lopez of Bermello Ajamil to lead this task. Mr. Lopez is a member of the Broward County Water Advisory Council’s Technical Advisory Committee and Vice-Chair of the Broward County Surface Coordination Committee and for the past 20 years has been involved with water control districts, regulatory agencies like SFWMD, FDEP and USCOE, and local communities and he is familiar with the issues, and ongoing stormwater projects in the county and his experience within the county is unmatched. We have also tasked Ross Engineering (a local CBE firm) to participate in this effort. Ross has worked extensively on stormwater management projects in Broward County and will be very beneficial in identifying information to be gathered during these meetings. LAGO will work closely with Mr. Lopez and Ross




storage lost in the system that will be incorporated in to the model conceptually. AECOM will use a “Terrain Processing Tool” to convert the LiDAR from the DEM format to a format readable by MIKE SHE / MIKE 11 (dfs2 file). The existing start date for the vegetation module will be modified to the 2060 and 2100 conditions for all grid codes and the land use vegetation file (dfs2) will be modified for the future conditions based on the future land use maps or zoning records as collected under the Data Collection and Review Task. For flood event models, the overland flow module is absolutely necessary to simulate the overland flow; therefore, the overland groundwater leakage coefficient file will be included to evaluate the surface water/groundwater interaction for the future conditions and modified during the calibration process. Special attention will be given to the overland flow configuration and simulation. The current version of the model uses some of the overland flow module cells through the use of appropriate flood codes to simulate storages within some of the drainage districts. This configuration may be revised since the paved runoff/drainage module in new 2017 version, adds “storage” to surface runoff (similar to drainage module but for ponded water). The overland module will also be revised and modified as additional survey information becomes available. The horizontal and vertical hydraulic conductivity will be included in all geological layers to account for surface water-groundwater interchange and revised during the calibration process. Drainage levels and drain codes will be modified representing 2060 and 2100 conditions.

percent, 1-percent, and 0.2 percent-annual-chance conditions). These methods include tidal forcing at current MSL explicitly within the modeling and resulting statistical calculations Stillwater elevations derived for these conditions include the effects of wave setup. For the purposes of mapping and zone delineation, additional analysis is performed to incorporate overland wave action and runup conditions. In order to meet the scope outlined by Broward County, the FEMA stillwater elevations and mapping criteria should be updated to meet future conditions at 2060-2069 and 2100 levels. From a coastal perspective, this would have impact to a number of components of FEMA’s assessment: a) Direct impacts on the location of the mean shoreline b) Impacts of the increased water depth on storm surge generation c) Erosion of the coastal beaches d) Impacts to the delineation of pre-frontal dunes and the protection such dunes provide e) Impacts to the resiliency of coastal protection structures f) Impacts to the delineation of buildings and development areas g) Changes in land use: i.e. changes to marsh/habitats due to a change in the inundation characteristics, increase in “wetted areas” that contribute to fetch h) Changes to the overland wave calculations i) Changes to the location and value of potential runup and overtopping calculations j) Impact to the choice of downstream boundary conditions for MIKE11/SHE implementation These factors would all contribute to the mapping of the coastal conditions. In order to address these topics from a future conditions perspective, there are a number of

proposed stormwater ponds and outfall control structures in MIKE-11 as needed to simulate attenuation of runoff from the future developments. Sea Level Rise Influence on Groundwater Table and Regional Storage - The unconfined Biscayne Aquifer underlies the majority of Broward County. This surficial aquifer is highly permeable, and many of the canals within the County are deep enough to have a direct connection to this aquifer. Any increase in sea level will be able to propagate through this highly permeable aquifer (likely several miles inland), and thus a regional rise in shallow groundwater levels will be manifested over much of the developed area in the County, which is mostly confined to an approximately 15-mile wide band along the coast. This rise in water table levels must be reflected in the initial conditions for the future conditions design storm simulations. This regional rise in the water table, combined with the higher coastal tidal levels, will increase the likelihood of flooding throughout much of the County through the following mechanisms: a) Higher water tables will reduce the available soil storage prior to extreme rainfall events, causing an increase in runoff. b) Higher tides will reduce the conveyance capacity of gravity-dependent canals and coastal discharge structures. There are several ways to update initial groundwater levels to reflect the impacts of sea level rise, including steady-state or transient groundwater modeling with variable coastal boundary conditions. For the purposes of this study, it is understood that the U.S. Geological Survey has already developed MODFLOW models representing groundwater elevations under future sea level conditions (2060-

Engineering to coordinate these meetings and document and itemize the data identified and collected during this process. An example of Mr. Lopez’s leadership in community outreach is his role in developing the communication and outreach program for Accreditation of the Broward Portion of East Coast Protective Levee (ECPL). As a Project Manager at the SFWMD Service Center, Mr. Lopez worked with community leaders, elected officials and media to inform the public about the process for obtaining Federal Emergency Management Agency (FEMA) accreditation of the Broward portion of the ECPL for FEMA’s Flood Map Modernization Program. The Communication Plan also defined the SFWMD’s role as owner of the ECPL, and communicated details of the comprehensive maintenance and operation of the levee that were on-going at that time. As the SFWMD representative, worked with the Communication Department in developing Communication Strategies focusing on elected officials, homeowner associations, civic groups and 298 Water Control Districts including the media tools and briefings to educate reporters about the safety and ongoing maintenance of ECPL and a link to Broward County website developed to address this issue. Mr. Lopez was also part of the team in charge of providing documentation showing that the Broward portion of the ECPL (38.3 miles) met FEMA’s criteria for accreditation for its new FEMA maps as requested by Broward County. Without FEMA certification, the ECPL could not be included in the FEMA flood mapping analysis which would have caused flood insurance concerns for residents in western areas of Palm Beach, Broward and Miami-Dade




The MIKE 11 portion of the model will include the following updates as listed below: Network Flood codes and coupling links will be modified for the entire model based on new project information from as-built drawings collected, capital improvement projects like the ones identified from City of Fort Lauderdale Stormwater Master Plan, and surveys performed under the Identification of Survey Needs Task. Flood codes used in the model will be added for the storage nodes only. AECOM understands that the existing conditions in the model already include surveyed cross sections for primary canals (C-11, C-13, C-14, C-42, and North New River Canal) and the secondary canals and tributaries are based on the 10-FT Digital Elevation Model (DEM). However, the cross-sections within the model will be updated as required based on the information collected from the Data Collection and Review and Identification of Survey Needs Tasks. Special attention will be given to the conservation of mass between MIKE 11 and MIKE SHE. Cross sections in MIKE 11 will be modified to assure they represent the same volume represented in MIKE SHE once the bank elevation has been surpassed. Downstream boundary conditions in the network will be updated based on the updated tidal information developed by the SFWMD or from the Zone A Coastal re-modeling efforts, if available. In addition, groundwater elevations for the future conditions and antecedent conditions (initial), as developed and provided by the County, will be incorporated into the boundary conditions for the groundwater portion of the model. The groundwater elevation is the output from MODFLOW groundwater models developed by the United

different options for methodology that could be employed, depending on the level of effort and its importance in meetings the County’s requirements. For clarity, DHI has separated these methods into three alternatives, of increasing complexity and effort, with a recommended middle ground approach, as described below. Alternative (1) At a base level, future conditions could be included into a coastal analysis via what is typically referred to as a “bathtub” approach. This essentially raises the predicted Stillwater elevations derived in FEMA’s assessment by the agreed upon sea level rise scenario giving a resulting future conditions percent annual-chance condition. This condition could then be used for downstream boundary conditions on the MIKE SHE/ MIKE11 model as well as used in an update to the coastal mapping. Under this condition, the mapping assessment would need to incorporate some assessment of factors a, c, e, and f delineated above in order to provide new overland wave modeling (using WHAFIS), dune delineation, limit of maximum wave activity (LIMWA) for the revised future condition maps. This is largely a desktop assessment that would require engagement with the County and stakeholders to estimate future conditions in terms of planning, building, beach maintenance, etc. Part of this effort would be developing tools to streamline and automate the assessment so that changes can be incorporated readily. One modeling component that may be of use is the use of the Sea Level Affecting Marshes Model (SLAMM, https://coast.noaa.gov/digitalcoast/tools/slamm.html) which predicts change in marsh type under sea level rise scenarios. This is best use for potentially assessing land use changes and could provide additional

2069). Our approach will be to review the outputs from these models, specifically the average wet season groundwater elevations, to confirm the suitability for use as initial conditions for the design storm simulations. We will develop a GIS based tool (utility) to quickly convert the MODFLOW output into the appropriate MIKE SHE input format (.dfs2). We will also review the soils and aquifer-based parameters in the County-wide integrated MIKE SHE/MIKE 11 hydrologic-hydraulic model to ensure reasonable values for hydraulic conductivity in the surficial aquifer. Just as importantly, we will review the soil moisture characteristic curves in the current MIKE SHE model. These relationships, in conjunction with the rise in water tables, will determine the reduction in available soil storage in the unsaturated zone (and thus the increase in runoff volume). We will employ the latest Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report to provide three regional sea level rise scenarios for 2060 and 2100 — one based on historical sea level change, one on medium sea level rise projections, and one for the high sea level rise projections. Then we will employ hydrodynamic and wave models to estimate the local sea level rise and the resulting 10-, 25- 50- 100-, and 500-year storm flooding based on the three regional sea level rise projections. If needed, we will apply regional ADCIRC plus SWAN models to include the effect of climate change on hurricane frequency and properties that change present day estimates of storm surge high levels along the Broward County shoreline. The localized high-water levels and water level hydrographs resulting from the projected sea level rise and

counties, the SFWMD presented specific engineering data about the ECPL so that FEMA could provide a “Provisionally Designated Levee” (PAL) designation. The PAL status would allow time for USACE and District to complete repairs and thereby be recognized as providing a 1 percent chance level of flood protection on modernized NFIP maps called Digital Flood Insurance Maps or DFIRMs (44CFR Section 65.10). To confirm the awareness that SFWMD was taking these steps toward certification, Mr. Lopez coordinated Broward County and eight communities (Weston, Sunrise, Parkland, Coral Springs, Southwest Ranches, Miramar, Tamarac and Pembroke Pines) adjacent to the ECPL to ask for their participating in a letter of agreement. Mr. Lopez also coordinated with South Broward Drainage District (SBDD), Coral Springs Improvement District/ Pine Tree Water Control District, North Spring Improvement District, Plantation Acres Water Control District. Sunshine Water Control District, elected officials at the County (County Commissioners) State (Representatives) and Federal Representatives. Task 2. Update the MIKE SHE/MIKE 11 Model. The MIKE SHE/MIKE11 model for Broward County will be updated in accordance with the outcomes of the community stakeholder meetings, recent modeling efforts and refined drainage and control structures data, projected land use changes, future groundwater elevations and updated tidal downstream boundary conditions. After the compilation of the more recent data sets considered necessary to update the model, LAGO will meet with Broward County staff to review the data and how it will be incorporated into the




States Geological Survey (USGS). This input data will represent groundwater elevations under future sea level conditions (2060- 2069) in accordance with the Unified Sea Level Rise Projection for South Florida (Compact, 2015). AECOM will develop a “Groundwater Conversion” utility to easily convert the updated MODFLOW output files to MIKE SHE/MIKE 11 input files to allow for future updates based on changes to the groundwater model or sea level rise projections. In addition to the tidal and groundwater boundary and antecedent conditions described above, the model also uses boundary conditions for the western boundary of the County. Water levels in the Water Conservation Areas are used as boundary conditions for both MIKE 11 (i.e. S9 Pump Station) and MIKE SHE (controlling groundwater levels west of the levees). After model development, AECOM will discuss with the County the need to develop scenarios to analyze the effect of a breach on the western levees. Accuracy of the simulation results of any model depends on the accuracy of model parameter calibration and validation. After the existing condition model is updated with the revised inputs, the integrated model will be calibrated for specific major storm events of recent years as required by the County. The corresponding stage/flow observations at available stream gaging stations, and available field data on existing flooding problems will aid in better calibration of model parameters and validation of the integrated model. AECOM will also use anecdotal or other type of information collected during the Stakeholder Meetings regarding the performance of the drainage system during the selected storm events.

information to both coastal and inland water analysis. Erosion of coastal beaches and changes to the shoreline position could be assessed through a modified Bruun rule or similar desktop based beach retreat calculation. The overland wave analysis, runup calculations, delineation of LIMWAs and pre-frontal dunes would maintain the methodology employed by the current ongoing FEMA coastal study. This option has limitations in that the storm surge impacts are not linear for lower frequency events. An increase in mean sea level would have a direct impact on the physics of the storm propagation over the shelf and the extent of landward inundation. This is likely to have some variability based on the storm characteristics, and can lead to a significant change in the overall statistics of the annual-chance stillwater elevation. The advantage of this method is its relative simplicity and level of computational effort. Recommended Alternative (2) Our recommended approach would incorporate all aspects that are part of Alternative (1), but would also include a rework of the stillwater elevations based on revised modeling under the 2060-2069 and 2100 sea level rise conditions. This would not consider any potential future impacts to the characteristics of the storms impacting the area (i.e. there would not be an additional storm set that would be generated) and the synthetic optimized storm/tide combinations generated as part of the ongoing FEMA study would continue to be used. This could incorporate any or all of the following: � The mesh geometry would be altered to account for a 2060 and 2100 SLR scenario. � The impact of SLR could consider the impacts to the land cover (through a SLAMM analysis) and which could be used to modify the mesh geometry

10-, 25-, 50- 100- and 500-year storm surge inundation provide the means to estimate changes in local flood patterns due to climate change, sea level rise, and storm events. The estimated water levels for the County provide the input to other hydraulic models (i.e., MIKE-SHE and MIKE11 models) that will estimate the inland surface flooding and groundwater/seawater intrusion. Model Updates to Evaluate Sea Level Rise Influence on Discharge Capacity of Coastal Structures - At all tidal outfalls in the model domain, updated tidal tailwater information from SFWMD will be used to develop time-varying stage boundary conditions. The Team recently incorporated similar information developed by SFWMD into the MIKE-11 model of the BCB. As part of this effort, the Team is testing the response of gated coastal outfall structures to the higher tailwater conditions resulting from three year-2065 sea level rise scenarios, in combination with statistically-derived storm surge projections. This process will identify which structures are vulnerable to sea level rise by comparing discharge capacity across an array of sea level rise scenarios and design storm return intervals. For the Broward County model update, we propose to review the simulated operating protocols of gravity-driven coastal structures in MIKE-11 for consistency with current SFWMD Water Control Atlas and modify if necessary. We will also check to ensure that the model accurately simulates the flows that would result from tailwater stages outside the ranges of original design parameters, as these structures were originally designed to operate over a fairly narrow tidal range. As part of this task, the modeling team will also coordinate with SFWMD to

model. LAGO recognizes that the strategy by County anticipates only nominal updates to the model for defensibility purposes, since the previous MIKE SHE model used for the FEMA study has been accepted. After the model updates, LAGO proposes to conduct a model verification process that will evaluate the accuracy of the model and its ability to reproduce measured data. In order to verify the model, LAGO and the county will select one or two recent storm events to apply to the model. LAGO and the County will also jointly establish criteria to evaluate the effectiveness of the model to reproduce measured flow and stage and any observed flooding that may have occurred during these events. By applying actual storm event rainfall data to the model, we can compare the model response to measured flow and stage data in the canal network to evaluate accuracy of the model. LAGO will review the results of the simulations completed to evaluate these actual events with the county relative to the agreed upon model evaluation criteria. It is likely, given the expected changes to the topographic and land use related input files, that the results of these initial model runs will not fully meet the evaluation criteria. In the meeting to review the results, LAGO will lay out a series of recommendations and a schedule to improve the model results. These recommendations will focus on structure operations and input parameters that control the timing and volume of runoff during storm events. Task 3. Development of a utility to routinely convert modeled future groundwater elevations to MIKE SHE/MIKE 11 boundary conditions. LAGO has already developed a conversion tool called ModFlowResToDfs. The purpose of




AECOM has specific expertise and experience in county wide hydrologic/hydraulic modeling calibration. AECOM will apply data extraction tools to compare model results with observed information and calculate goodness of fit metrics as previously discussed and agreed upon with the County. In addition to the comparison of flow and stages where the information is available, AECOM will compute water budgets for the entire County and by sub-areas, as required. These water budgets will be checked for reasonableness and compared with similar information prepared by the SFWMD. Parameters that will be adjusted during the calibration process will most likely be the following: � Horizontal and vertical hydraulic conductivity (Kh, Kv) � Overland – groundwater leakage coefficient � Manning’s n (overland flow and MIKE 11 cross sections) � Cross sections and cross sections levels to remove instabilities � Control structures operations Once the model has been developed, calibrated and verified, the modified MIKE SHE/MIKE 11 model will be simulated for approved 10-, 25-, 50-, 100-, and 500-year storm events. The model results will represent flood elevations under future conditions (2060-2069) in accordance with the Unified Sea Level Rise Projection for South Florida (Compact, 2015). The results of this 100-year model simulation will serve as the basis for the updated Future Conditions 100-year Flood Elevation Map. The updated hydrologic and hydraulic model produces stage elevation data for the various storm events for each grid cell throughout the watershed. This peak stage elevation data along with the stage elevation results from Coastal Zone A Re-modeling will be used to delineate the 100-year, 24-

and parameter definition for a future conditions run. � Erosion of coastal beaches and potential modification to the bathymetry along the coastline due to expected changes could be considered through either basic analytical formulations such as a modified Bruun Rule. � Alternatively, more complex multi-dimensional modeling could be employed to estimate erosion rates under SLR scenarios. These assessments could be used to modify the mesh geometry for a future conditions run. The final modified setup would not be re-calibrated (given that future conditions are estimated and not known), but could be used in conjunction with the storm forcing as part of the ongoing FEMA study. The landfalling and exiting storms generated as part of the ongoing FEMA study would be run on the modified 2060 and 2100 coastal storm surge model. The FEMA study is currently run in ADCIRC. Under this option, this framework would remain intact in order to maintain consistency with the FEMA study. Assumptions as part of this work: 1) The storm set and statistics will remain the same as was used within the FEMA study. 2) Modifications to the mesh would be final, as the computational effort for this portion of the work would make it impractical to continually re-run every time there is a change. 3) High Performance Computing would be sourced in order to complete this phase of work. 4) Model setups and input (synthetic storm winds) would be made available by FEMA. Alternative (3) The final option would involve developing an integrated MIKE SHE/MIKE 11 and MIKE 21 model that handles interactions between inland flooding, coastal flooding, and groundwater. This is beyond what is required at a minimum level for a future conditions

identify the need for future upgrades to flood protection infrastructure. If any such upgrades have already been identified by SFWMD, we will incorporate those changes into the future conditions modeling. The MIKE 11 results (flows and stages) of the model simulation of the future sea level rise scenario will be examined for each coastal structure, and will be compared with the current conditions flows to identify those structures with significantly reduced capacity under future conditions. Export and Mapping of 100-Year Floodplain Results - Once the model simulations are complete and have undergone our thorough QA/QC for stability and reasonable results, mapping the final 100-year floodplain results will be simple, straightforward, and easily reproducible by following the steps below: 1. The MIKE ZERO Toolbox (part of the MIKE SHE/MIKE 11 standard installation) will be used to export the gridded maximum depth of overland water (DOLW) from the MIKE SHE results file for the 100- year design storm simulation. 2. Using the grid-to-shapefile tool, the MIKE SHE output grid will be converted into a GIS point feature class. 3. The resulting feature class will then be transformed using ESRI ArcGIS into a triangular integrated network (TIN). 4. The DOLW TIN will then be overlaid onto the detailed LiDAR data to develop 100-year future floodplain surface. From this surface, contours similar to the 1977 Broward County 100-year flood elevation map can be easily generated in ArcGIS using standard tools. The procedure above is similar to that recently employed by the Geosyntec Team on the BCB LOS project for the SFWMD. Project Management

this tool is to convert MODFLOW result files into time-varying dfs2 and dfs3 files, which is the DHI software format. In the likely event, that the MODFLOW grid is not square, the user may choose to resample the MODFLOW results by using nearest neighbor or bilinear interpolation methods. The dfs2 and dfs3 files generated by this tool can be imported into MIKE SHE to specify boundary and initial conditions. For this project, LAGO will carefully review the files from the regional MODFLOW model and test the conversion tool. Improvements or adaptations to the tool will be made as required to meet the needs of Broward County. LAGO will also meet with representatives of Broward County to ensure that the tool is generating files in the method that best suites the County’s needs. Task 4. Development of MIKE SHE/MIKE 11 model run for the approved 10-, 25-, 50- 100-, and 500-year storm events. LAGO will work closely with Broward County to define the methods that can be successfully applied within the project constraints to define the nonstationary storm events for 2060 and 2100. One study, completed by Michelle Irizarry, P.E. for the SFWMD in 2016 (Determination of Future Intensity-Duration-Frequency Curves for Level of Service Planning Projects) focused on the future condition storms in south Florida. This study was well received, but it acknowledges that the methods used include significant biases that effect the prediction of low frequency (i.e. 100 yr) storm events. Other tools, such as the University of California (San Diego)’s LOCA project - Statistically downscaled projections for 32 CMIP5 model, may provide predictions of future nonstationary storm events that




hour event floodplain within the watershed. In order to seamlessly integrate the results from both models, without any voids or tie-in issues, an “Elevation Merging” utility will be created. The purpose of the tool is to compare the elevation results within a single grid, optimize the results and finally develop a single grid file that will eventually be used to develop the 100-year Flood Elevation Map. WISE, developed by AECOM’s Programming and Research and Development Team in the late 1990s, was the first all-inclusive software in the floodplain mapping industry designed specifically for FEMA flood studies. Our philosophy has been the same ever since: we focus on automated tools and processes that link engineering components to GIS outputs. AECOM uses a series of industry-standard software to support the tools we have custom developed. AECOM will develop a similar tool for the use of Broward County staff after the completion of the project. The floodplains within the watershed will be automatically tied into the adjacent watershed floodplains. The floodplains will be mapped to include transition areas between basins, address tie-in issues with adjacent watersheds and revise/refine FEMA flood zones automatically within the watershed. Additional info on GIS Data Management on pages 304-305 The MIKE SHE/MIKE 11 model files will be hosted in AECOM’s file servers. These servers will be accessed by members of the team through a VPN connection. Personnel from subconsultant firms involved in data collection and review tasks will work out of the AECOM office. For other tasks and to facilitate and expedite work progress, the team will take advantage of the input file system

assessment, but is included here for completeness. This method could provide useful information as to the physics of the interactions between the different sources and how future conditions may impact those interactions. Typically, in a hurricane induced event, there is a lag between the storm surge and the overland flow. This lag depends on the storm’s forward speed and other characteristics. Flood assessments typically treat the inland and coastal flooding events as separate, and combine them for mapping via statistical methodologies. The interactions are best developed for a well-studied fairly recent storm impacting the area. For Broward County, available information will be used to build a system that is fully integrated to look at combined effects of coastal and inland flood characteristics. The integration of full synthetic storms is required deriving a relationship between rainfall intensity curves with the storm position and characteristics. Once this is estimated, the synthetic storms used in the coastal analysis could be run in fully integrated mode in order to derive combined responses for the cyclonic set of storms. Statistics from a purely MIKESHE /MIKE 11 application at the appropriate return periods could be combined with this response surface to derive fully integrated maps. Future conditions could be extrapolated using modified SLR curves for 2060 and 2100. There is still considerable uncertainty with respect to the impact of climate change on hurricane characteristics. Some consensus has been reached with respect to the fact that hurricanes are expected to increase in intensity, but there is uncertainty with respect to how much, and what the ramifications are to other characteristics, including rate of occurrence. Due to this uncertainty,

Successful project management depends on establishing well defined roles and levels of responsibility and continuously communicating with the team so that obligations are fulfilled and exceptional quality and service are provided to the County. Our Project Manager, Mark Ellard will guarantee that the project team understands the goals for this project. Our strategy for successful project management includes thorough project planning to anticipate and avoid potentially negative events. During project implementation, the Project Manager will monitor project health by meticulous cost and schedule tracking and will identify issues, define root causes, and implement corrective action when needed. Our Project Manager and technical staff will also look to employ cost-saving measures when possible. This process will ensure that Geosyntec delivers the best value to the County. Regular communication will be accomplished through progress review meetings to be held bi-weekly. Coordination with the County, community stakeholders, and Geosyntec will be documented in meeting minutes and phone logs. Geosyntec’s approach to successful project completion starts with strong project management and effective communication, and then is supported with resource commitment. The Project Manager, Mark Ellard, will be the focal point for project communication, coordination, and administration for all components of the contract work. He will ensure that appropriate resources are allocated to the project and County’s expectations are met. Our Project Manager, Mark Ellard, will provide multiple contact channels to the County’s Project Manager so that he

have a smaller bias, but this method may be more expensive to implement. Once the method for predicting future, non-stationary storm events is selected, LAGO will complete the process of generating the storm duration curves. A Technical Memorandum that summarizes the methodology and generated curves will be provided to the County (and SFWMD, if appropriate) for review and comment. The approved curves will then be applied to the MIKE SHE/MIKE 11 model to generate predicted flood elevations for these future rainfall scenarios. Task 5. Development of a utility to update and run the approved storm events with updated version of MIKE SHE/MIKE 11. For this task, LAGO anticipates the need to develop a utility that will convert results from Coastal Zone modeling efforts into the appropriate MIKE SHE/MIKE11 format for use as boundary conditions, both in the canal network, and in the overland component. LAGO will work closely with County (and SFWMD, if appropriate) staff to carefully evaluate the format and compilation of the coastal zone model. Relevant data in the canal network will be extracted and converted to dfs0 format for use as MIKE11 boundary conditions, while grid-based inundation results will be extracted and converted into time-varying dfs2 files to define overland flow boundary conditions in the MIKE SHE model. LAGO is also very familiar with the tools within the MIKE ZERO toolbox that allow multiple MIKE SHE simulations to be launched using batch files in a command prompt mode. As needed, LAGO will modify the existing DHI crafted tools into a Broward County specific utility that will provide the capability to launch multiple design




used by MIKE SHE/MIKE 11. In this program, each data set is input through a separate file (i.e one file for topographic elevations, one file for canal network, one file for land use, one file for cross sections, etc.). Therefore, different members of the team will work separately on their own task/input file. A main file (.SHE) is then defined to point to each individual input files and set up the model run. Model Input and Output reviews will be performed across teams on a regular basis using WebEx collaboration system. WebEx system allows video conferencing and screen sharing. However, face to face internal team meetings will be scheduled on a monthly or as needed basis to make sure the entire team is working towards one goal that is to exceed the County’s expectations and complete the project on budget and on schedule. Coordination meetings will also be setup with ACG and WSM to kick-off each task assigned to those firms (Public Outreach for ACG and Survey for WSM). Weekly coordination meetings will be scheduled for each task. Project Management It is the responsibility of the management team to develop and tailor a project specific, systematic plan for communication, information management and project controls. Although each unit of the team has a role in the communication network, it must be managed as a complete system. AECOM’s systematic approach includes establishing a Memorandum of Understanding or other jointly developed set of communication protocols before the work begins. The development of the communication protocols is a collaborative process involving the key stakeholders. The communication management

and for consistency with FEMA studies, it is proposed that FEMA’s storm set be maintained with current rates and characteristics. It should be discussed with the County as to whether an increase in rainfall intensity from the hurricanes is appropriate for future conditions for certain scenarios and recurrence intervals. The relevant approaches for precipitation and rainfall intensity are addressed in subsequent section of this proposal. This method would allow for a fully integrated assessment of hurricane induced flooding across the county that would not rely on statistical relationships between physically linked processes. However, some assessment would still be required to ensure that lower frequency (2-percent, 1-percent, and 0.2- percent annual chance) conditions are driven purely by hurricane conditions. The 10 year return period would likely still be performed using decoupled analysis methods similar to what is employed by FEMA currently as the rainfall and coastal conditions leading to this return period are likely decoupled and these conditions are not generated by hurricanes or tropical storms. This method would require a transformation to a fully integrated MIKE framework, so the FEMA ADCIRC model would need to be transformed and integrated into an integrated MIKE SHE / MIKE 11 and MIKE 21 system. Following the numerical modeling of the integrated storm characteristics, FEMA methodology for overland wave calculations, runup, etc would be maintained for the full mapping study. Following the determination of the appropriate methodology (which may be undertaken prior to contract execution, or confirmed as part of the proposed scope of work), efforts will be made to proceed with the development of the operational

Our Project Manager, Mark Ellard has extensive experience gained through the completion of numerous projects with similar objectives and management of multi-disciplinary teams. Schedule Tracking and Control. Geosyntec Project and Task Managers monitor schedule performance with Microsoft Project® software by establishing the following project baselines: � Task and subtask timelines � Milestone events (e.g., deliverables, receipt of approvals/permits) � A critical path for achieving milestones and the project endpoint Once finalized, project baselines are presented to support staff and subcontractors so that all parties understand how their particular task schedules impact overall project progress. If review of the project schedule indicates a potential impact to project milestones or endpoints, the Project Manager will investigate the problem and may take one or more of the following actions: 1) reallocate resources to compress the schedule; and/or 2) attempt to reorder the work elements to maintain milestone dates. The Project Manager is committed to meeting the required 12-month project completion schedule and has the authority to allocate the staff resources necessary to ensure timely completion of critical tasks.

storm simulations. LAGO will carefully document these tools and train county staff to successfully apply to tools. Task 6. Updating of the 100-year flood elevation map, including the GIS project containing the geodatabase files and support layers. LAGO will generate the 100-year flood elevation map. The map will include contour lines showing the predicted 100-year flood elevation. LAGO will provide Broward County with the GIS project and geodatabase files that were used to generate these maps. Task 7. Development of a utility to update the 100-year flood elevation map, according to new simulations/results. During development of the flood inundation maps, LAGO will develop GIS and model based utilities that will convert the MIKE SHE/MIKE11 results into GIS format. LAGO has already developed a useful tool called “Hydroperiod from Microtopography”, which is found in the LAGO Toolbox and produces hydroperiod and water depth maps at a higher resolution than the typical MIKE SHE model grid. The Broward County model is based on a 500-ft grid, but grid-based topographic data sets are usually at much higher resolution, sometimes with grids as small as 5-feet. This tool converts model results from the 500-foot grid to model results at the smaller grid, and therefore, allows for more accurate calculation of inundation depth at the high-resolution topographic scale. LAGO will work with the County to adapt this tool or to create a new one to generate the 100-year flood elevation maps for Broward County. This will be particularly useful as new coastal zone flood inundation studies are completed. Task 8. Presentation of preliminary and final results to the County and




strategy will: � Identify communication roles and responsibilities � Assure that all decisions are clearly communicated to the appropriate parties � Establish means and methods of managing and controlling the flow of information � Set out clear requirements for schedule, quality and cost control reports � Provide for a comprehensive system of identifying, tracking, managing and communicating project risks � Conduct weekly and monthly job meetings to monitor progress of critical milestones, submittals and changes � Assure regular and timely communication of significant project events, problems and challenges to the project stakeholders As with any project, staying on schedule/managing project budgets are critical factors in the overall project success. To assist in meeting those goals we have adopted a regimented approach to overall Project Management, including development of a Project Management Plan (PMP) at the beginning of each project. AECOM’s PMP is intended to be a living document developed with input/feedback from the entire project team. The plan will address how work is assigned, how communications are handled with the County and how we will manage scope, schedule, cost and quality. Our team’s PMP, provides for continuous monitoring and improvement and includes performance measurement techniques to confirm that budget and schedules are met throughout the project. Our overall project management strategy is to effectively manage, communicate, and implement the requirements of the technical plan, and to support Broward County in the accomplishment of all project

framework to allow for model development and processing. When the necessary coastal analysis is completed the relevant results and identified coastal model integration tasks will be executed. This will likely include some elements of boundary and mesh development, tidal and storm description development, and necessary model tools to facilitate the rapid processing and automation of the approach for incorporating the coastal zone analysis. The MIKE SHE / MIKE 11 model update will be executed in coordination with the selected coastal integration approach. With the benefit of our multi-team approach, these activities may proceed concurrently, allowing for an efficient delivery schedule. The main tasks will include executing the model updates and revisions for future conditions are identified in Task 2. Following the model updates and determination of methodologies detailed in proceeding sections, the future conditions scenarios will be developed using the Scenario Management tool within MIKE Operations, for each of the 10-, 25-, 50-, 100-, and 500-year storm events. The appropriate Sea Level Rise scenarios, based on guidance from the Southeast Florida Regional Climate Change Compact Sea Level Rise Work Group (SEFRCCC, October 2015), and County other resources, will be identified. The constitutive elements of each scenario to be modeled will be reviewed with the County and documented. These model scenarios will be defined and recorded within a database containing all input characteristics and model settings, and will provide a means for future revision and additional scenario execution. The boundaries (or model integration approach) used for the coastal regions will be determined in the

stakeholder groups throughout the map adoption process. LAGO will work closely with Broward County to define the prepare presentations, flyers, and other graphic materials as needed throughout this process. It is anticipated that the initial effort will focus on municipalities and the 298 water control districts. Our team includes staff that have completed this type of effort many times and have a thorough knowledge of the expectations of these organizations. We also have the ability to define programs to reach out to individual citizens and citizen driven organizations such as homeowner associations as needed. Task 9. Submittal of Draft Summary Report containing a detailed description of the modeling process, assumptions and calibration results, including a summary of CRS potential creditable criteria and recommendations. LAGO will prepare a Summary Report that details the efforts completed throughout the model development and verification/calibration effort. This report will incorporate the Technical Memorandum describing the process to define the nonstationary storm events and the methods used to produce the model results. Hydroperiod from Microtopography User Input Windows An important element of this report will be a full review of the County’s CRS ranking. The LAGO team will complete this evaluation early in the project time line, so that model results and model documentation can be crafted to obtain the maximum credits available through the CRS program. LAGO will present the findings of the project to the County prior to submitting the draft document to the County for review and comment. Task 10. Submittal of Final Summary Report containing a

The progress schedule will be updated and revised on a weekly basis to show the actual progress of the work performed, updates and/or revisions, and the effect of those events on work not yet completed. It means that AECOM has a world-class quality program with tools in place to assure it is followed. It means that AECOM consistently applies a set of quality practices throughout the company, regardless of where the work is performed or managed. It means that AECOM’s QMS is built upon the eight foundational principles that lie at the core of the ISO standard, providing a strong footing for positive results. The outcome?

previous task. MIKE SHE and MIKE 11 boundaries will be developed from guidance provided by SFWMD, and County provided groundwater future conditions analyses. The development of the future conditions boundaries and rainfall intensity-duration-frequency curves is described in the following section. DHI has implemented a comprehensive project management program for managing staff resources and project deliveries, as well as quality assurance, in accord with our business standards. These procedures are detailed in DHI’s Quality Assurance policy. Project management controls are put in place by the project manager to ensure that projects are tracked with respect to execution and budget tracking, so that and potential variance from schedule or are recognized and responded to as quickly as possible. Any such variances are addressed according to the project risk management plan. With the assembled team members, we will have the resources to meet the 12-month delivery time frame. With a project of this scale, it will be important to develop a schedule that identifies key milestones, which include scheduling the initial stakeholder meetings, completion or suitable delivery of the coastal zone remodeling, and completion of the model update and scenario development tasks.

Some of the CRS activities, along with the maximum possible points, that can earn credits based on the model update are listed below: Under 300: Public Information Activities ─ Elevation Certificates ─ Map Information Service ─ Outreach Projects ─ Hazard Disclosure Under 400: Mapping and Regulation Activities ─ Flood Hazard Mapping ─ Higher Regulatory Standards ─ Flood

The DHI team includes several Certified Floodplain Managers (with one based in Fort Lauderdale) and will work in tandem with the County’s CRS Coordinator to evaluate CRS creditable criteria and propose recommendations to the involved communities. This process will start by identifying the most immediate ways that additional credits may be earned, which are expected to be in

We will employ the criteria detailed in the NFIP CRS Coordinator’s Manual for identifying qualifying credit activities and calculating credit points. Based on review of the project scope and Coordinator’s Manual, it appears the public information and floodplain mapping tasks of the project may qualify for additional CRS Credit points.

Data Maintenance ─ Stormwater Management. Based on AECOM’s experience with CRS, we will evaluate Broward County’s current CRS activities and ensure that specific components of this project are undertaken in a manner that will maximize the potential for earning credit in accordance with the CRS program criteria. The following is a list of elements within each of the CRS activity that could potentially earn additional CRS points based on the modeling efforts: � As part of the community outreach process, AECOM will prepare and deliver presentations, as needed, before stakeholder and public groups that will count as credits towards the “Outreach Projects” activity and as part of the map development process. Under the Hazard Disclosure category, with the recent model update and 100-year elevations defined, buyers can be notified of potential flood hazard to the property. � Flood Hazard Mapping is the key activity which can potentially add maximum credit, since it relates to the new flood studies within the County and mapping of special flood related hazard areas due to the recent map update. � Higher Regulatory Standards can be enforced based on the map update and improve credits by protecting existing and future development and natural floodplain functions that exceed the minimum criteria of the National Flood Insurance Program. Credits under Flood Data Maintenance and Stormwater Management Activity will also be taken into consideration with the model update and floodplain map development. The CRS also recognizes that floodplains and watersheds change over time, driven by many natural and manmade changes. Good

the areas of public information and warning and response. This is to be followed by an evaluation of the potential gains that each community in the County could receive through improving their individual CRS programs in these areas, and discussing these recommendations with the CRS Coordinators of the local communities within the County. The primary project scope for CRS improvements will be to evaluate potential increase of credit points to improve existing community rating. Based on latest CRS report Broward County has rating of 7 that provides 15% and 5% flood insurance discount for structures in and outside of SFHA respectively. Potential upgrade to rating 6 with increase discounts by 5%. As stated in the current CRS manual increase rating to level 6 requires community to fulfill not only point credits based on activities but also to achieve certain prerequisites. Prerequisite for rating 6 classification is related to Building Code Effectiveness Grading Schedule, which this proposal does not address. The DHI Team will work with community to evaluate CRS activities showing great potential to increase credits. Especially activities related to Mapping Regulations (series 400) and Flood Damage Reduction (series 500) could be potential candidates for significant credit point increases. The DHI Team will assess and rate each of the activity in regards of maximum potential credit gains and additional resources needs. The DHI Team will present an action plan to the county officials for the review, acceptance and execution. Successful execution will require cooperation and support between flood management staff and other key community stakeholders, which will be facilitated by the members of the Project Team. In general, mapping and regulations are the activities in which the most points

the project it is recommended to review the County’s current CRS Coordinator’s Manual Activity Checklists and Documentation Checklists to identify current credit allocations. These checklists may be used as to identify opportunities to implement activities that would receive credits in new categories or enhance credits in existing categories. A list of current and recommended scope tasks would then be developed that if implemented would maximize the CRS credit points available and potential for improving the County’s CRS classification. The purpose of maximizing the CRS credit points is to assist the County to improve their CRS classification and corresponding flood insurance premium discounts percentages. Based on the CRS Eligible Communities Effective October 1, 2016, Broward County’s current class is 7, which corresponds to a 15% discount for SFHA flood insurance and a 5% discount for non-SFHA flood insurance. Also, a CRS class of 7 corresponds to 1500 to 1999 CRS points. Thus, a key task will be to compare the County’s current point total to the anticipated additional project points to determine if the County’s classification may be upgraded (to class 6 or better) to provide higher CRS premium discounts. The CRS creditable project activities will be presented to the community stakeholders to ensure the stakeholders are aware that the project may be used to increase their communities CRS credit points and potentially CRS classification. Communicating the potential CRS benefits of the project to stakeholders early in the project schedule may enhance stakeholder participation in the project.

company in the Florida dedicated solely to completing CRS evaluations and providing recommendation to improve a ranking score. For the part of the project related to Community Rating System questions, LAGO teamed with Earl King, CFM, from CRS Max Consultants, Inc. CRS Max specializes in the National Flood Insurance Program’s Community Rating System (NFIP/CRS). As the only consulting firm in the nation concentrating exclusively upon assisting communities with their CRS programs, CRS Max Consultants offers focused intensity and expertise. The CRS Program awards points for flood mitigation efforts undertaken in 19 separate activities with 94 elements. CRS Max Consultants has gained a strong reputation for mastering this complex program and assisting communities’ efforts to maximize their points earned, resulting in millions of dollars in flood insurance rate reductions. Flood Hazard Mapping, Activity 410, includes six elements, each with specific requirements. Additionally, points for mapping are available through elements embedded in many of the other activities. Included in the 2017 CRS Coordinator’s Manual is a new section specifying sea level rise projections acceptable to CRS. Mr. King will play an important role by reviewing Broward County’s CRS program and making recommendations for maximizing the credits that may be available through this project.




floodplain management acknowledges this, and includes thinking about how floodplains might look in the future under different scenarios. Increased impervious surfaces through land use changes in developing watersheds, new fill in floodways, rising sea levels, changes in natural functions, and many other factors contribute to the character of the future with which floodplain managers must cope. The Coordinator’s Manual incorporates additional acknowledgement of—and credit for— community efforts to anticipate the future insofar as it relates to flood risk and natural floodplain functions and climate resilience, and to take actions that can mitigate any adverse impacts that could materialize. Credit is provided for communities that provide information about areas (not mapped on the DFIRM) that are predicted to be susceptible to flooding in the future because of climate change or sea level rise. � To further enhance the ranking class of the County, AECOM with the support from County can demonstrate that it has programs that minimize increases in future flooding and receive credit for using regulatory flood elevations in the V and coastal A Zones that reflect future conditions, including sea level rise. In addition to the activities as listed above, CRS activities within 500-600 Series can also be reviewed to identify multiple opportunities to increase the total points and put Broward County over the current CRS rating of 7.

To maximize the number of credits earned, the Project Team will recommend specific regulatory standards and identify locations suitable for greenspace preservation and/or reclamation that may then be discussed openly and evaluated among local policymakers.

In order to update the existing rainfall file for the 2060 and 2100 future conditions and when selecting the 10-, 25-, 50-, 100-, and 500-year storm events, it is imperative to select high intensity storm events and project it for the

future taking in to account the climate change and sea level rise. Selection of the storm events for calibration will be based on evaluating historical rainfall records over the past ten (10) years and identifying the events with maximum intensity over a three (3) day period. Upon discussion and subsequent approval from the County, the selected event will be converted to the precipitation rate file to be used in the model. As requested by the County, a separate study will be performed to evaluate the pattern and timing of major storm events affecting the project area. The standard approach to develop flood maps assumes a static or stationary rainfall pattern that is often constant for the entire project area. With drainage areas, as large as Broward County, these assumptions may produce unrealistic results. In previous studies, and through review of available literature, the AECOM Team has identified that the storm event distribution and spatial patterns used in the simulations have a significant effect of peak flows and peak elevations. For example, during the development of the 100-year flood model for the Kissimmee Basin, the AECOM Team, in collaboration with the US Army Corps and Engineers (USACE), evaluated several rainfall distribution patterns. It was concluded that for large areas, more conservative results are obtained when a different pattern is used for each one of the subareas of the project domain. In this case, the flood map would not be the results of a single model simulation but an envelope or collage of results obtained through several modeling scenarios, where for each model simulation the worse part of the storm event is located over certain

methodologies to accomplish two separate outcomes. Method A. The IDF curves currently employed by Broward County for the design and development of drainage systems will be utilized as the baseline condition under this method. Additionally, the Future Conditions Wet Season Groundwater Elevation Map developed by the County includes future precipitation changes based on the downscaled Community Climate System Model (CCSM) by the Center for Ocean-Atmospheric Prediction Studies (COAPS) at Florida State University. To remain consistent with the County’s standards for design, our team will utilize the baseline condition for future projections and employ the data utilized by COAPS to develop future IDF curves and precipitation totals for the County in the years 2060 and 2100. The approach used will be reviewed against standard guidance and procedures to ensure that the evolution of relevant variables (precipitation, temperature and evapotranspiration) over the period of study are consistent with methods for downscaling and localizing climate information Method B. The National Oceanographic and Atmospheric Administration (NOAA) publishes precipitation and IDF information across the United States, and provides spatially varied precipitation totals across Broward County. This information will be analyzed and extrapolated against varying global climate models outlined in the National Climate Assessment, published by the U.S. Global Change Research Program to determine projections and probabilities of high and low precipitation amounts, intensities, durations, and frequencies. Given the uncertainties in projections of changes in rainfall, and desire to examine specific return

result future changes to South Florida’s rainfall are difficult to predict. For example, probabilistic model simulations cited by the Intergovernmental Panel on Climate Change suggest that average wet season rainfall in South Florida could either increase or decrease by as much as 10% in the decades of 2046 through 2065 (Ref: IPCC, 2013: Annex I: Atlas of Global and Regional Climate Projections). However, the intensity of extreme rainfall events, especially those resulting from hurricanes, will possibly increase due to warmer temperatures (ref: SFWMD Interdepartmental Climate Change Group, 2009: Climate Change & Water Management in South Florida). Stronger hurricanes and tropical storms would likely increase rainfall volumes and intensities for the rare design storm events considered for the Broward County model update. Because of the uncertainty inherent in future rainfall projections, we propose to take a probabilistic approach to quantifying potential changes to the 100-year floodplain in response to non-stationary rainfall conditions. This could be accomplished by conducting multiple simulations with increased design storm rainfall volumes and intensity. To accomplish this, the SFWMD’s current design storm rainfall hyetographs would simply be scaled up by a range of percentages (say, 5%, 10%, and 15%) to bracket the range of probable future wet season rainfall increases predicted by climate modeling. The resulting flood maps could then be used to identify areas of the County particularly vulnerable to increasing precipitation. It is important to note that higher average wet season rainfall would also impact future water table elevations. Therefore, in addition to testing the possible

If, for example, the state decides to construct or operate the runoff collection facilities different due to short term variations such as drought or prolonged and frequent area-wide flooding, the modeling needs to prepare for such variance and be able to quickly show the localized and regional results. Any effective modeling must include unsteady-state simulations and variable boundary shifts.

of changes in climate and land use patterns. In the project’s draft report [Irizarry et.al, 2016], the authors describe the development of DDF/IDF curves for 40-50 year periods centered at years 1970, 2030 and 2060. The selected method was based on US Bureau of Reclamation (USBR) bias-corrected and statistically-downscaled climate projections from the World Climate Research Programme (WCRP) Coupled Model Intercomparison Project (CMIP) phase 5 (CMIP5). Biases in the modeled precipitation extremes, were found to be significantly large, especially for low frequency events. Section 5.2 of the report by Irizarry et al. details the limitations of the used datasets and approach. In particular, it is found that the downscaled model runs from USBR significantly underestimate precipitation extremes during the current baseline period (centered around 1970) and that these (negative) biases are of a larger magnitude than projected changes (generally increases) in precipitation extremes from the current baseline period to the two future periods analyzed. The SFWMD project used a Multiplicative Quantile Delta Mapping technique to correct for these biases. The approach followed in the SFWMD work appears to be one of the most current and scientifically sound instruments to estimate extreme rainfall events under nonstationary conditions in Florida. It is possible that some of the following statistically or dynamically downscaled climate model products could show smaller biases in simulated extremes: • FSU’s CLAREnCE10 project - Dynamically downscaled projections for 3 CMIP3 climate models. SFWMD staff planned to contract FSU to have this project rerun based




areas of the County. Based on our experience, if a rainfall pattern that has an area with larger rainfall intensity than the surrounding areas (like in concentric circles of iso-hyetal lines) is applied to a drainage area, the condition that results in larger peak flows and higher peak elevations corresponds to the distribution where the center of the storm (area with largest intensity) is placed directly on the centroid of the drainage area being studied. Another important factor is the timing or nonstationary character of rainfall events. In this case, the strongest part of the storm (area with higher rainfall intensity) is not static, rather it moves along the project domain. The worst case for our analysis will correspond to those events that show a West-East movement, causing the peak of the storm to follow the flow towards the tidal discharge, exacerbating flooding conditions along the way. Studies that evaluate all the possible rainfall patterns usually require large amount of data, budget and an ample schedule. AECOM will evaluate the gauge adjusted radar rainfall data available and/or any available rainfall patterns study and will discuss with the County whether this information is to be included in the model. If the County decides to use the results of rainfall patterns in the modeling effort, AECOM will use the aforementioned ”Rainfall Conversion” utility to generate the rainfall patterns required to run the model using the type of input MIKE SHEMIKE 11 files that are available within the software. ET Reference Evapotranspiration The existing reference evapotranspiration file will be modified with a new dfs file covering the time period for 2060 and 2100 to simulate future conditions. Reference

frequency storms, changes in long-term weather patterns will be assumed to affect the intensity of a specific return-frequency storm, rather than evaluating all possibilities across frequency-intensity space. Additional considerations relating to Precipitation and Climate Change: To enable the County to simulate updated scenarios after the completion of the Project, the variable IDF curves from each scenario developed under Method B will be referenced to the corresponding global circulation models utilized in its development.. � Additionally, the precipitation patterns of Broward County are strongly affected by the land-sea temperature gradient and sea/land breeze phenomenon. As such, the available studies regarding future changes in land-sea and sea/land breeze will be examined to determine how such changes may modify precipitation patterns and intensities during the wet season. The granularity of such changes will not be well modeled by global/regional climate models, and will require local appropriate methods. Changes in the seasonal cycle of mean sea level will be examined, analyzed and quantified as the seasonal temperature difference in the South Florida region evolves with a changing climate. Sea levels are directly related to the heat content of the ocean, and changes in oceanic heating between the summer and winter months will affect the seasonal cycle of sea levels. The implications of this are that changes in seasonal sea levels may coincide with South Florida’s wet season, which in turn will affect the capacities of ground storage and drainage systems, as well as discharge rates. � Local Surface Temperature and Evapotranspiration will play a role in the initial soil moisture and groundwater levels, and the

changes in extreme rainfall, the future conditions modeling to incorporate non-stationary conditions should consider the likelihood of wetter antecedent conditions. To this end, the USGS future conditions MODFLOW-derived groundwater levels could be updated to reflect potential increases in average wet season rainfall.

on CMIP5 climate projections. However, this project will likely not be finalized until at least early 2018. • University of Idaho’s MACA project - Statistically downscaled projections for 20 CMIP5 models. • University of California (San Diego)’s LOCA project - Statistically downscaled projections for 32 CMIP5 models. The LOCA project methodology seems to be the most promising since it uses a downscaling technique that (in theory) better preserves extremes. In addition, it is based on the most recent CMIP5 global models. LAGO will meet with Broward County to discuss the pros and cons, and cost of applying the various non-stationary storm event prediction methods in terms of their ability to reproduce observed precipitation extremes their usefulness in estimating future projected changes in precipitation extremes. LAGO believes that the LOCA method will likely produce the storm events with the least bias; however, the application of the LOCA method would be more time-consuming than the method applied in the recent SFWMD study. Another aspect to determine is the duration of storms that Broward County would be interested in for the analysis. Rule 14-86 of the Florida Code states that in determining critical storm duration, typical durations up through and including the 10-day duration should be considered for closed basins and up through the 3-day duration for basins with positive outlets. The At-site Regional Frequency Analysis method used in the SFWMD work assumes a constant shape parameter across a limited set of durations. This method is acceptable for the analyzed 1-7 day storms; however, the methods tends to




evapotranspiration will also be affected by climate change. For this key element and other aspects related to climate change, the AECOM Team has incorporated 300 Engineering to the team and more specifically, Dr. Fernando Miralles. The AECOM Team will rely on Dr. Miralles’ expertise to define a reference evapotranspiration condition that includes the effects of climate changes for future condition modeling

drawdown and drainage between storm events. The significance of this role is not known directly for future conditions, and may not be a driving influence for the short term flood events studied here, particularly as the groundwater levels for the initial storm condition will be supplied by external analysis. Standard methods for appropriately downscaling and disaggregating these variables will be provided, consistent with the selected climate scenarios and guidance provided by the County, SFWMD and other agencies. Following development of the requisite boundaries and scenario inputs, the specific scenarios for the design events will be documented and assembled within MIKE Operations, which allows convenient methods for managing and automating model runs and results processing. These scenarios will be executed and documented in summary reports for project records. Our approach to handling the evolution of the key parameters is described for both coastal modeling issues, and Precipitation, Soil Moisture, Evaporation, Evapotranspiration and Temperature. Coastal Approach As described in the approach for Coastal Integration Task, there are a number of potential approaches for handling the interactions of FEMA approaches for current conditions, and incorporating global, regional and local guidance on sea level rise, and the interaction with coastal storm modeling, both under existing methodologies used by FEMA, and DHI’s experience in applying these methods to future conditions for climate change. The recommended approach, as well other options explored, will provide a robust and defensible treatment for managing the evolution of sea level rise and the related dynamics of storm surge, waves, and inundation

break down for shorter and longer duration storm events. Therefore, there may be a need to use Quantile mapping techniques as implemented by Tetratech (2015) to temporally downscale projected daily extremes to sub-daily durations. Another part for consideration is that once the n-day extremes are determined, LAGO will need to make an assumption about how to distribute the rainfall in time. LAGO believes that the NOAA Atlas 14 temporal distributions, which are derived from current climate data for durations of 6, 12, 24 and 96 hours, are applicable in the future. It is known that uncertainties in the estimation of the shape parameter in fitting a Generalized Extreme Value (GEV) distribution (as part of the At-Site Regional Frequency Analysis method) based on a limited number of data years, produces large uncertainties in extremes with a low frequency of recurrence. This would be the case of 100 and 500 year extremes. Papalexiou and Koutsoyiannis (2013) developed a method for bias correcting the GEV shape parameter, which was later extended by Carney (2016). This method could be used in this project to reduce the uncertainty in the less frequent rainfall events. LAGO anticipates some difficulties in predicting the year 2100 storm events due to the fact that the CMIP5 runs end in the year 2099. To overcome this detail, it may be necessary that estimates centered around the year 2080 be considered instead. LAGO will review this information with Broward County staff and a jointly decide which year to use for this task. Finally, it is known that there are about 120 downscaled model runs for which future DDF curves were fit and adjusted. The SFWMD was




to meet the requirements for representing these phenomena under non-stationary future conditions. The resolution of Precipitation, Evapotranspiration and Temperature for local studies, based on a climate assessment scenario contained in a GCM/RCM requires that parameters are statistically resampled for local application. This is especially true for extreme events indicated by longer return interval storms, such as the 100 and 500 year storms. There are three main families of methods available for statistical downscaling: perfect prognosis (PP), model output statistics (MOS), and stochastic weather generators (WG) (Maraun et al., 2010). Of these, MOS approaches, suitably applied, would be recommended for extreme event simulations and impact modeling at local scales. The DHI team has experience in developing solutions using both the MOS and WG methods. MOS may be either a change factor or bias correction method, with relevant limitations found for the change factor analyses, when looking at extreme events. Other MOS methods that address changes in mean, variance, and the full probability distribution are recommend for the study of extreme events. MOS methods can include provisions to account for seasonality, so that some description of this variability in preserved in the downsampling process. (DHI Climate Change Guidelines (2016), See Sunyer et al. (2015b) for further details). The WG approach uses local records and changes in statistical characteristics from RCM simulations to generate the required downsampled variables. One determining characteristic is that MOS methods presume that model biases are time invariant, which is not presumed with a WG approach. Despite this difference, either method would likely provide reasonable

particularly interested in 5th, 50th and 95th percentile. It would be important to know if Broward is only interested in the "worst case scenario" (95th percentile) or in others.




estimates for key variables for the future conditions scenarios. Based on the available resources for understanding and representing south Florida’s future climate conditions and key variables, we propose to handle the ongoing evolution of these variables using the following methodology. 1. Selection of appropriate climate scenarios and Regional Climate Models most appropriate for the proposed analyses and period of study. This will include guidance from the SEFRCCC Working Group (SEFRCCC, October 2015), SFWMD, USACE and others to ensure consistency of the approach, along with the guidance from Broward County on the most appropriate guidance for future conditions flood mapping. 2. Extraction of the relevant scenario and model predictions for the relevant water resources variable (precipitation, temperature and evaporation 3. Determination of the appropriate change factors for downsampling and localizing these variables. This will include expectations for extreme events and more frequent storms under analysis, which will likely utilize different statistical methods. 4. Application of the change factors to determine the key variables population characteristics, and the specific values to be used for each scenario and design event. 5. Creation of appropriate time series using methods for disaggregation and to create the specific boundaries needed for model simulation. This can include both local guidance the development of a Weather Generator to provide suitable temporal detail for simulations. 6. This process will be developed as a boundary creation utility within MIKE Operations, such that subsequent analyses and revisions can be completed with greater ease in the future, simply by




changing the source data for future climate scenario simulations, and the model statistics to be used in determining change factors, localization, and the procedures for disaggregating the statistics to create the input time series. DHI has established routines and workflows within MIKE Operations for change factors and building and managing weather generators for these purposes, making these tasks as straight forward as possible. These capabilities will be applied to allow for use in the current study, as well as updating of methods and recalculation to incorporate future guidance and data availability. Further details on the procedures for development of the Weather Generator for building extreme event rainfall and other relevant time series are provided on pages 71 and 72 To provide some further context for this discussion, an excerpt from DHI’s Climate Change Guidance for Water Resources is provided in the following section, relating to the development of estimates for the key water resources variables for future conditions scenarios and extreme events (see pages 73 to 74)

6. Describe the prime Consultant’s methods to provide the County the ability to easily run updated scenarios and display the mapped results, given new SLR projections, future groundwater elevations, FEMA remodeling results, etc. (5)

The conversion process will be done using a utility hereafter referred as “Rainfall Conversion” utility that will be developed by AECOM. The utility will be developed with appropriate software tools that will enable the process to be automated for any design event in the future. AECOM’s Team has extensive experience in creating such tools, one recently developed for Miami-Dade Water and Sewer Department, was to generate hydrographs for future storms that included climate change and sea level rise. AECOM will develop a “Groundwater Conversion” utility to easily convert the updated MODFLOW output files

The DHI Team will develop a utility to take a particular scenario results and publish the resulting flood depths to a map meeting the specified requirements. There are a number of ways to map the scenario maximum water level results to flood depths at the appropriate scale. DHI has developed utilities to perform these tasks from a variety of models, including MIKE SHE and MIKE 11, and will bring this experience and techniques to help meet the current task requirements. For example, using a combination of MIKE 11 water level results and MIKE SHE grid results, a composite, detailed water surface elevation may be converted to flood

Methods to Efficiently Update Scenarios Per the scope of work described in the RFP, the selected consultant will develop utilities or software tools that will facilitate efficient updates to the model based on revised future groundwater conditions and FEMA Zone A coastal modeling. The consultant will also develop a utility to update the flood elevation digital map based on new model results; and a GIS based tool (utility) to quickly convert the MODFLOW output into the appropriate MIKE SHE input format (.dfs2). Geosyntec is experienced in the development of ArcGIS Toolbox of

In order to enjoy this type of flexibility in performance there are actually many ways to accomplish it with modeling. One way is to modify the MIKE code to be more user- friendly. Another is to add new utilities at the front-end to allow manipulation of the input parameters. We look forward to accepting the challenge as we have done for numerous projects, our project manager will implement a partnering approach that allows for constant integration between the County staff and Higgins' staff throughout the model design

LAGO has developed many software tools over the years to be used in project work related applications. Some of those tools has evolved to be more user friendly, and they have been encapsulated into a toolbox (http://www.lago-consulting.com/lago_toolbox.html). For conversion of MODFLOW files, LAGO has already developed a tool called “ModFlowResTodfs”. The purpose of this tool is to convert MODFLOW result files into time-varying dfs2 and dfs3 files that are easily imported into MIKE SHE. In the event, that the MODFLOW grid is not square, the user may choose to resample the MODFLOW results




to MIKE SHE/MIKE 11 input files to allow for future updates based on changes to the groundwater model or sea level rise projections. AECOM proposes to utilize the prominent data processing tools as listed below. The functionality of each of the tools, which will be transferred to the County for their use, is summarized below: � Rainfall Conversion Utility – The purpose of the utility is to automate the processing of rainfall data for any design event to different rainfall patterns to be utilized in MIKE SHE/MIKE 11 model. Terrain Processing Utility – Terrain processing utility tool will use the existing LiDAR data, identify the anomalies and voids in the data and automatically merge the changes with recent aerial photography, land cover GIS feature classes, as-built and data from survey to create a single topography file in the acceptable model format. Groundwater Conversion Utility - This specific utility is to easily convert the updated MODFLOW output files to MIKE SHE/MIKE 11 input files to allow for future updates based on changes to the groundwater model or sea level rise projections. � Elevation Merging Utility and Flood Elevation Map Development Tool – The merging tool is to integrate the results from the updated MIKE SHE/MIKE 11 model and Coastal Zone A Model by comparing the elevation results within a single grid, optimize the results and finally develop a single grid file that will eventually be used to develop the 100-year Flood Elevation Map. Updating the 1% Annual Chance Flood Hazard (100-year flood) elevation map will be achieved by AECOM with the development of a utility that imports the new,

elevations and mapped onto a high resolution Digital Elevation Model. This processing is built into the MIKE Operations platform, and will be customized to meet the requirements of this task. These results may be displayed in a variety of formats within the MIKE Operations platform and web portal. The second step in the flood elevation map development will develop a utility to publish and annotate the flood depth map for the select scenario (ie: the 100-year scenario, for future condition 2060-2069). The utility will create the map similar to the referenced 1977 image, along with a grid and flood zone boundaries, in format similar to the 2014 DFIRM. This utility will be built using an acceptable GIS platform and procedure, such as ArcGIS Pro to allow for robust map production, customization and further development, as necessary. Other alternatives are available with which our team has expertise, (including native GIS components within MIKE Operations, QGIS and web methods) that may be used to provide a more efficient, or open source alternative, if this is requested by the County. This map development and publish utility will allow for ease of recalculation and update, based on revised calculations at any point in the future. DHI will deliver the model configuration within the MIKE Operations model platform, which is designed to enable efficient operation and control of model runs and result dissemination. The relevant capabilities that this approach will provide include model automation, boundary condition handling, data conversion, extraction, and processing. As configured for this project, the MIKE Operations platform will provide the ability to update boundary and input information dynamically, on an as

geoprocessing tools to provide our clients with the means to update calculations as new data is made available. Geosyntec staff recently completed the draft ArcGIS toolbox geoprocessing tools for the Stormwater Infrastructure Criticality Analysis project for Pinellas County, FL. The tools provide a user-friendly method for County staff to update the criticality calculations by running custom GIS tools as needed. The tools allow the user to run the analysis on future updated datasets as well as evaluate the effect of changes to the factor scoring scheme on the analysis results with minimal effort required. Also, the tools are nonproprietary (source code provided as deliverable) and are run as tools in the native ArcGIS environment, so the client has the flexibility to make updates to the tools in the future if needed due to major changes to the input data, calculation methodology, etc. Similarly, it is anticipated that an ArcGIS Toolbox of geoprocessing tools may be developed for this project. The toolbox would include user-friendly tools to reprocess FEMA Coastal A zone model results, convert MODFLOW output files into MIKE SHE input files (.dsf2) and combine the steps needed to convert model results to updated floodplain mapping into a single tool / utility. In addition, subconsultant Taylor Engineering developed GIS tools that fully automate and streamline mapping for FEMA. These tools efficiently process terrain data, performs approximate hydraulic analysis for Zone A creation and refinement, and re-delineates Zone AE floodplains. The continued development of advanced GIS tools allows for greater overall efficiency and product quality, without compromising engineering judgment. It is anticipated that

process. This collaborative approach assures close coordination among team members to address the complexities of any code changes or utility development project.

by using nearest neighbor or bilinear interpolation methods. The dfs2 and dfs3 files generated by this tool can be imported into MIKE SHE to specify boundary and initial conditions. LAGO will carefully review the format of the regional MODFLOW model and test the application. LAGO will meet with representatives of Broward County to ensure that the tool is generating files in a method that best suites the County’s needs and that can be easily imported into MIKE SHE to serve as the boundary condition for the storm event simulations. LAGO staff will work closely with county and SFWMD staff to review and document the format and composition of model results from coastal flooding projects. With that information in hand, we will be able to use our software development experience to make a software tool that reads the coastal model results and converts it to the DHI software format. Those water levels would be applied as boundary conditions at the appropriate locations in the canal network (i.e., MIKE11 component), as well as boundary condition to the overland component of MIKE SHE. If the output from the coastal model is transient, it will need to be converted to both dfs0 and time-varying dfs2 files. Another existing tool in the LAGO Toolbox is the hydroperiod_from_microtopography.html tool. This tool computes the water depth at the finer resolution for each time step by using a bilinear interpolation. The topography elevation could be in different units (i.e. feet instead of meters) and in a different geographical projection and grid rotation with respect to the model result files. After processing the time steps of interest, the tool can provide water depth and levels at the finer resolution. LAGO has the




updated FEMA Coastal modeling results into a FEMA schema-based ESRI geodatabase. This utility will be developed in an ArcGIS Desktop environment and will generate the requisite geospatial map products from the MIKE SHE/MIKE 11 engineering cross sections and hydrologically enforced digital terrain data. Each generated feature class in the geodatabase will include FEMA appropriate attribution. The utility will automatically update existing features within the geodatabase with the most recent results generated from the utility process. This utility will amend the appropriate geodatabase feature classes with each successful iteration. Once the geospatial flood data has been updated, the FEMA standard map template will be dynamically retrofitted with the revised information from the feature classes along with the appropriate labeling, in keeping with the current FEMA approved Guides and Specifications documentation. In addition to the development and utilization of the above prominent tools, AECOM will also use tools that have been developed or will be developed to do the following tasks: � Interpret results from the model based on several metrics. � Graphically represent the model results and compare against observed data � Transfer data from multiple different platforms to a single platform � GIS-Model integration. The AECOM Team has extensive experience in programming and database development that will be used to the fullest extent to perform the above functionalities and make sure model development, calibration, validation, processing and presentation of results is performed in an efficient and effective manner.

needed basis, through simple provision of new boundary information, or a complete new scenario for analysis. Using the Scenario Manager, additional scenarios may be developed for analysis with little additional effort, building on existing scenarios and configurations. This allows the ability to readily update a scenario with new information, such as boundaries and initial conditions that are required for evaluation of new SLR projections, along with revised model inputs (urban conditions and land use information), parameter estimates, and related forcings (precipitation, temperature, and evaporation) that will change for subsequent evaluations. In order to simplify the approach to running the model with revised input information, boundaries, and forcings, we will deliver a web interface that allows the County to simply provide update information and develop an alternate scenario. This approach has been used for a number of projects using MIKE SHE and MIKE 11, and will provide flexibility and economy in evaluating new scenarios that do not typically require extensive model development. In order to maximize the utility of this approach and simplify its use by the County and its stakeholders, we propose to host the platform and the web interface, while enabling appropriate users to access the desktop component, MIKE Workbench, for configuration, use and further development. Tool development is a basic activity within MIKE Operations, which includes Python scripting to automate and execute any conceivable task. These features will be used in the subsequent utility developments, as appropriate. Flood Map Development A web mapping tool will be created within the proposed Operations framework,

Taylor Engineering’s GIS tool development expertise will be utilized to develop customized tools for the current project.

proven ability to produce simple, easy to use, utilities to speed the development and application of complex models. LAGO will produce similar tools as needed to ensure the successful completion of this project and will work diligently to make sure that tools developed in the process meet the specific needs and requirements of Broward County.




AECOM fully understands the benefits of GIS, and how GIS is integral in development of the Flood Elevations Map. AECOM manages GIS through an enterprise data management model. AECOM deploys a centralized enterprise database system (DBS) ArcSDE utilizing SQL Server. The GIS data is served through ArcGIS via a Citrix application server.

to access all relevant source information and scenario results, and automate the creation of the required floodmaps. This will allow the user to easily revise floodmap guidance, within a controlled and documented workflow. The end result will be an archival level flood map, with digital and web versions available for dissemination and discussion with community stakeholders. Output will be configured to include results files and dynamically developed flood map outputs, so that the results of any analysis may be shared rapidly and with a minimum of effort. This will include an internal web portal built for the evaluation of flood map results, and the ability to publish to a specifically developed format as requested in the RFP. At that point, the map may be shared via a public or a stakeholder-focused web portal, as required. This approach is well supported by the MIKE Operations platform, and has been used for the display and exploration of results from MIKE SHE in several integrated surface and groundwater studies. This capability may also be used for results from other models (both DHI and external models and results). Further capabilities to display and interact with the scenario model results will be provided through a web visualization interface. This will include the ability to view flood map limits, animate future flood scenarios, and display this information on elevation products, terrain models, and aerial/satellite images. DHI has several component based approaches to the workflows and display tools. This allows the user to incorporate results from a variety of modeling environments and data sources, and build visualizations that meet the particular communication and audience needs. We suggest the adoption of this visualization capacity within the web framework described




above, however a confirmed approach will be developed in collaboration with the county and the project team. (see figures pages 75 – 78)

7. Describe the prime Consultant’s proposal to ensure proper communication and public outreach, for the project as a whole, within Broward community, including water utilities, municipal stakeholders, local communities, and neighborhood groups, and the willigness to meet the proposed time. (5)

The AECOM Team specializes in public involvement and public communications specifically for high profile projects that have significant regional benefits or impacts. Our team believes, wholeheartedly, that listening to stakeholders, informing them, showing respect and compassion for their feelings and needs, and developing a relationship with them is in Broward County’s best interest. The County, with the required support from the AECOM Team, will schedule three (3) initial Stakeholder Meetings to introduce the community to this project and highlight the benefits. The meeting will occur with all partners, such as municipalities, utilities, private developers, elected officials, subject matter experts, within the North, Central and South areas. AECOM will prepare the following for the meeting: � Project Synopsis � Project Goals and Objectives � Project Schedule � Map Presenting the Model Network with Major Canals � Existing 100-year Flood Elevation Map with Underlying Parcels � Map Identifying the Canals with Recently Surveyed Cross Sections � Broward County Model with Latest LiDAR Information � List and Location of the Drainage Features and Structures (control structures, pump stations, etc.) already included in the model for each area, municipality and/or drainage district. The main purpose of these meetings is to gather information related to new projects constructed beyond the 2014 update, or not included in the original model development, with respect to drainage systems, control structures, pump station controls,

The DHI Team will assist with the stakeholder participation meeting and provide associated follow up. As directed, these early meetings will likely be focused at the onset of the project with the relevant authorities (municipal, water and drainage districts) who have input into local analyses and boundaries relevant to the development of the future conditions model and scenarios. Depending on the outcome of these meetings, individual or group follow up will be scheduled to provide further information exchange and description of the selected modeling approach, and well as response to any feedback received. Concurrently our team may also be tasked as a resource for assisting in the public process and the development of communication materials on technical and policy information; particularly concerning climate change issues facing Broward County, the methods and rationale to be used in the study, and FEMA’s Community Rating System and its impact on Broward County flood insurance rates. The Project Team will provide comprehensive assistance in the delivery of information and substantive dialogue with the affected communities, partners, and stakeholder through developing and executing a communication strategy, in cooperation with Broward County. This strategy will consist of communication and outreach guidelines addressing each audience type, technical guidelines for sharing information and study results with these audiences, and through digital tools for collaboration and results,

Effective stakeholder involvement is vital to the success of the project. Therefore, the selected consultant must have a well-established plan for effective communication with and active participation from all stakeholders throughout project implementation and have the capability to implement the plan. The Geosyntec Team anticipates that stakeholder communication efforts will begin at project onset and move forward in parallel with the technical model development tasks of the project. Initially, we will work with the County to identify the key stakeholders that will be involved in the project and verify the key individual(s) within each stakeholder organization. It is anticipated that this will involve communication with local representatives from 23 special districts, 25 water utilities, and 31 municipalities within the County. In addition to local stakeholders, effective communication with regional, state, and federal stakeholders such as SFWMD, FEMA, ACOE will be vital to project success. Also, coordination with stakeholders outside the County is important to ensure that stakeholders involved with the regional scale plans such as the Comprehensive Everglades Restoration Plan (CERP) and the Lower East Coast Water Supply Plan are sufficiently informed of the project and have opportunities to provide input. Communication with private stakeholders such as the Sierra Club and others is also important. We understand that the County has worked hard in the past to establish forums for

The County will benefit from Higgins' knowledge of the benefits received from other projects like this in the past. As stated earlier, not only were the public stakeholder groups invaluable in understanding their concerns but many times excellent solutions arise during the discussions. The input by peers, such as engineers and modelers, can provide great ideas and save a lot of time avoiding going down useless trails either in code or in the development of utilities.

The primary focus of the public outreach portion of this project will be on governmental stakeholders such as county, municipal, and 298 water management district personnel. The informational needs of these stakeholders may vary from what be needed for a program to disseminate information to the general public. In this section, we will first discuss the proposed methods to ensure communication with governmental stakeholders and then with the General Public Stakeholders. Governmental Stakeholders The information to be conveyed will be focused on the needs of the governmental entity and specific project needs and expected results. In the initial meetings (Task 1), the outreach program will explain the purpose of the project and will seek to gain buy-in and support in executing the project. It will be imperative to have clear and open lines of communication during the data collection and model verification process. At the start of the project, meeting with governmental stakeholders will focus on providing background and identifying how they may participate in the project as well as documenting specific needs they might have to be confident in the results. For example: � What is the project and how will it benefit the Governmental Stakeholders? � What tools will be used and what are our data needs – Can the Governmental Stakeholders help in filling the gaps? � The Community Rating System – Will this project help the Governmental Stakeholders in this matter? � Expected project




gate operations, and canal modifications. Since the flood map corresponds to future conditions, these meetings will also be used to gather information regarding master plans and capital improvement programs planned by the stakeholders that could have an impact on the flooding conditions. One of these master plans is the Master Plan for the City of Fort Lauderdale. Information about the projects being identified by the City will be reviewed and discussed during the corresponding stakeholder meeting. Additionally, the Master Planning efforts currently being carried out for the City of Fort Lauderdale include the development of an ICPRv4 hydrologic and hydraulic model for the City and the development of a comprehensive geodatabase including more than 5,000 stormwater features and a high-resolution LiDAR. This information will be incorporated in the development of the Broward County MIKE SHE / MIKE 11 model, where applicable. If required, and if accepted by Broward County, follow up meetings will be scheduled with individual stakeholders to address each one of their specific needs. Upon consensus from all parties, a scoping document along with schedule and budget will be revised and presented to the County for their discussion and approval. AECOM recommends holding quarterly meetings with all the stakeholders to provide the project progress and discuss any outstanding issues during the project, from conception to delivery and adoption of the flood elevation maps. This will avoid any potential delays and finish the project within budget and on schedule. Two sets of additional community stakeholder meetings will be held towards the

including a dynamic web representation of the flood maps for the future condition scenarios. Stakeholder meetings will likely need to be carried out with the involvement of County, SFWMD, local municipalities, local drainage districts, state agencies, business interests, and homeowners’ associations. Technical information will be disseminated to the Broward County Water Advisory Board Technical Advisory Committee (TAC) and Surface Water Coordinating Committee (SWCC) and SFWMD, if required. The Project Team will provide public outreach services to coordinate, plan, and strategize these meetings, as well as provides services to help facilitate these meetings, and to document the process. In keeping with the request to coordinate activities under this project with NFIP CRS requirements, special attention will be provided to the outreach scope and content, meeting facilitation, and documentation to advance Broward County’s community rating and the benefits it will afford citizens and businesses. The Project Team will deliver a final report that documents and explains the project methodology and stakeholder process. The report will detail all model revisions and improvements, and any necessary documentation regarding recalibration procedures and results. Procedures for the development of the mapping products and output will be provided within the final report. Results from production runs for the future conditions scenarios will be provided in detail, allowing community members and stakeholders to understand the analyses and outcomes. The resulting scenarios may also be published to the web portal, for interactive use and visualization. The NFIP CRS

communication with local stakeholders. These existing interlocal forums include, but are not limited to, the County’s Water Advisory Board, Technical Advisory Committee, the Surface Water Coordinating Committee, and the Broward Water Resources Task Force. We anticipate that these existing lines of communication will facilitate stakeholder communication and participation for this project. We will assist the County to facilitate effective stakeholder meetings. This may include preparation of emails, mailers, social media posts, websites, and / or phone calls to ensure all stakeholders are well informed of meetings. Also, we will ensure that agendas, informational handouts, and comment forms are prepared for each meeting. Presentations to inform the stakeholders of the project background, goals, status of map development process and input from stakeholders needed will be prepared. Portions of meetings may also be organized to facilitate discussions between stakeholders and the project team in multiple small groups during the meeting. We will establish a methodology to organize and track stakeholder comments and questions. Comments will be organized by comment type and whether the comment does / does not require follow up action. Comments regarding model development needs such as areas where additional details or updated data are needed are considered of high importance. All comments will be tracked to ensure action items are properly addressed and stakeholders are aware of actions taken to address their comments. Direct communication with certain stakeholders after or in between

results and deliverables – Do the Governmental Stakeholders have specific needs? As the project continues, we would propose to keep these governmental stakeholders in the loop regarding important topics like the initial evaluation of Broward County’s Community Rating System score, model updates and verification, and the development of nonstationary design event. At the final meetings envisioned in Task 8, the focus will be on summarizing the project methods and results with special attention to What’s Next. Some aspects to be included are: � Synopsis of the model updates (with highlight on data they provided) � Demonstration that the model is verified � Summary of methods used to develop the nonstationary design storms � Results of design storm simulation � Summary of expected improvements in the CRS score What’s next? - Coastal zone modeling is ongoing - SLR predictions may change The format of the data to be presented at the Task 8 meeting will vary depending on the topic. For example, a synopsis of the model update and verification would be included in a power point presentation, but it would also make sense to provide a 1-page fact sheet that addresses this topic. A similar approach could be used for the nonstationary design storms and the CRS scoring evaluation. Study results that include flood inundation maps may be presented in the power point presentation, but it would also be useful to produce large-scale maps in both hard copy and digital format that can be reviewed in detail. General Public Stakeholders It is not anticipated that community outreach will be required for the general public at this stage in the project. However, we think it may




end of the project to present preliminary and final results to the stakeholder groups following the map adoption process, if needed. The quarterly meetings proposed earlier in this section will drastically reduce the probability of dealing with controversial issues at these final meetings, since all the assumptions and input information would have been already discussed and consented throughout the duration of the study. An important part of the stakeholder meetings and community outreach program will be to communicate the public of potential for earning credits towards the Community Rating System (CRS) program for the NFIP through the activities and deliverables part of this project. We believe in getting feedback from the community and interested stakeholders early in the development process, especially for large, high-profile projects. Our team understands the power of public education and project support. The AECOM Team, which includes the Adam Consulting Group (ACG), a firm that specializes in designing and implementing strategic public engaging and community outreach programs, will prepare the required documentation which will include meeting material and meeting minutes and will highlight any additional actions as required by the County or other parties. AECOM will use ACG experience in organizing and assembling Stakeholder Meetings to guarantee all input provided is compiled, evaluated and applied in the project. Our guiding principle for public involvement and stakeholder outreach is to assist our clients in keeping in touch with and communicating complex subjects to stakeholders. We have developed specialized skills to empower stakeholders with the information

review and evaluation will be documented as part of the reporting task. Information regarding project execution in conformance with CRS requirements will be included, along with recommendations for continuing CRS program management.

meetings is anticipated to address certain comments. Meetings including the general public may also be of benefit. We will coordinate with the County to determine at what stage of the project these meetings may best occur. The purpose of these meetings is to present preliminary model results and project status to the public and listen to comments and concerns they may have. In our experience, it is beneficial to provide a means for citizens to submit comments outside of meetings through an internet site that has the ability to upload comments. Public comments will be organized and tracked similar to other stakeholder comments. Proper care and adherence to procedure and organization will allow this process to best obtain information useful to the model update process and in turn best reflect the interests of stakeholders in the flood mapping.

be useful to discuss some ideas and suggestions for this activity in case they are needed in the future. The information that will be conveyed to the general public will vary depending on the media format as well as the timing relative to a mapping project; for instance, general information about flood risk, flood hazard mapping, and the importance of flood insurance is valuable at any time and can be conveyed through posters, ads, flyers, etc.; while information about the mapping process, changes in flood risk designations that will result from a new map, and the appeal/protest periods may be best provided at the scoping and post- preliminary stages through newspaper articles and presentations in local government meeting places. Prior to developing specific mechanisms for conveying information, it will be valuable to develop and prioritize the information the public needs. The list will serve as a means of ensuring the important information is covered through a variety of means and at the appropriate times. Such a list might include information about the following topics (see page 55) With the list of topics above, the LAGO Team will begin to determine how best to present the information to the target audience. For instance, a question/answer format that personalizes the information for the audience might be best for the general public in Broward County. Also, the LAGO team will analyze the list to determine what information can be depicted graphically rather than verbally. The most important information should be conveyed through a variety of outreach formats. Before developing the outreach mechanisms, it will be useful to conduct an informal survey to determine what outreach and




they need to provide Broward County with informed feedback. We communicate in visually appealing and creative ways, using print media, video, web design, social networking, electronic and print displays, public events and presentations among other tools.

marketing methods have been used in the past for similar activities, including the City of Fort Lauderdale’s on-going efforts to present their stormwater master plan. In developing new outreach mechanisms, information about the degree of success of similar tools already used can be applied. Any existing tools can be modified and re-used as appropriate. The following is a preliminary list of outreach and marketing mechanisms, and the information that might be conveyed. In all cases, mechanisms that target especially the Spanish-speaking audience should be prepared in Spanish. (see pages 57-60)

Our team also includes the firm of CRS Max, a firm that is dedicated solely to evaluating CRS credit criteria and recommending methods and procedures to improve a client’s ranking. In this section, we will summarize some relevant MIKE SHE/MIKE11 and flooding projects and document examples of CRS evaluation studies. Evaluation of Flood Effects in Golden Gate Estates Under Build Out Conditions The Golden Gate Estates, located in Collier County, is classified as rural residential and approximately 10,000 of the lots have not be developed. For this project, Collier County was concerned that full build-out in the Golden Gate Estates would raise the Base Flood Elevation and subsequently contracted with LAGO’s Peter deGolian to develop the tools and models to complete this evaluation. Mr. deGolian was working at Atkins when the project began, and completed the project as a LAGO employee subcontracted to Atkins. The first task in this project was to determine the area and volume of the typical home pad in the Golden Gate Estates. A GIS based utility was written to read the elevation in the center of a home pad from the Digital Elevation Model (DEM) and then interpret the surrounding DEM points to define the extent of the pad. The volume of each pad was then calculated based on average side slopes and averaged across the entire Golden Gate Estates. The second task was to modify the existing DEM and create a built-out conditions DEM that includes a home pad on each undeveloped lot. The built-out conditions DEM and a modified land use file were then brought into the

Experience described in the proposal: There have been a select few applications of MIKE SHE for floodplain delineation, outside of the Broward County project completed in 2012. Recently, DHI and its partners have completed a FEMA CTP program project in Flagstaff, AZ using a detailed MIKE SHE / MIKE 11 model for a detailed urban setting, coupled with a watershed based approach for the surrounding watershed. This model was designed to provide advanced capabilities in assessing floodplain impacts due to urbanization, climate change risks, and watershed impacts such as wildfire. Though this project is in a different setting, many of the fundamental requirements are similar. We evaluated the integrated surface and groundwater flood risks in an urbanized setting and the project was successful in delivering an advanced floodplain analysis tool to assist the City with its floodplain management and CRS program. This project is included in the following project descriptions. DHI has extensive experience and demonstrated leadership applying specialized numerical models to meet FEMA floodplain mapping requirements. This specifically includes applications where more

Other Relevant Project Experience Modeling Services for Surface Water and Groundwater Management The Collier County (County) Groundwater Protection Ordinance (GWPO) was adopted in 1991 and incorporated into the County’s Land Development Code to safeguard groundwater aquifers which are the major sources of potable water in Collier County. To protect these critical groundwater resources, Collier County established groundwater protection zones and a series of wellfield risk management special treatment overlay zones around public water supply wellfields. These zones are the basis for land use management regulations as they pertain to activities that may impact groundwater within the specified zone. The protection zones were last




year model for the Miami River Basin (C-6 Basin). Results from this modeling effort were used to develop the FEMA DFIRM of a large portion of Miami- Dade County. AECOM updated the Floodplain Management Plan for CRS requirements for Sarasota County. This included a review of the plan to be consistent with CRS requirements. AECOM also prepared the Draft Public Outreach Strategy Plan for Local Mitigation Strategy (LMS) and CRS compliance. AECOM has been working with the City of Miami Beach on the development of the Resilience Program, including the review and revision of the land development and building codes as well as with assessing vulnerability and developing adaptation strategies on critical infrastructure. AECOM’s Coastal Modeling Teams have supported a range of clients with understanding potential sea level rise through detailed modeling and mapping of future scenarios. Projects have ranged from supporting confidential utilities, to some of the nation’s largest ports including Long Beach and Houston, to state and local agencies including a sea level rise study for Pinellas and Hillsborough Counties, Florida, and a Sea, Lake, and Overland Surge from Hurricanes (SLOSH) model for evacuation planning for the Florida DOT. AECOM’s Planning and Engineering Teams have worked with the San Francisco Public Utilities Commission (SFPUC), supplier of potable water and wastewater to the City and County of San Francisco, as well as to wholesale customers, to incorporate sea level rise resilience into the planning and design of the wastewater system upgrades and improvements. AECOM’s work with the SFPUC resulted in a sea level rise vulnerability checklist that the City

detail is needed to meet complications due to challenging floodplain environments, large and complex scale issues, coastal and groundwater interactions, as well as interactions with urban infrastructure and flow controls. The applications and advanced capabilities demonstrated in these studies, particularly in the integration of surface and groundwater analyses, coastal and inland studies, urban and management complexity, are similar to the issues facing Broward County and are relevant for meeting the requirements in this Scope of Work.

generated from a groundwater model on year 2003, and are outdated. Thus, the primary objective of this project is to update the wellhead protection zones to current conditions. Collier County has been using single county-wide integrated surface water/ground water MIKE SHE /MIKE11 model (1,400 square miles) as the basis for water management decisions throughout the county. The model completed in year 2011 has been used to evaluate projects to manage discharge to the estuaries, improve water quality, increase groundwater recharge, and reduce runoff to the canal network. For this project, LAGO updated this model to more current conditions and then developed telescoped models around the wellfields in order to delineate capture zones by using particle tracking analysis. Since the model integrates groundwater and surface water, LAGO also used the model results to evaluate potential contributions to the wellfields from the surface water bodies and canal network. In addition, the model results are used to evaluate the potential impact zones from known contamination sites. Village of Estero Stormwater Plan For this project, LAGO was asked to update the MIKE SHE model developed for the South Lee County Watershed Study. The stage and flow in the canals flow out of the South Lee County area into and through the Village of Estero must be correct. This flow and stage data will be extracted from the regional model and applied as boundary conditions for other models developed to evaluate flooding in the Village of Estero. Watershed Management Plan (Naples, FL) Collier County is seeking more than $20 million in RESTORE funding to implement a project that

AECOM is providing planning and design services for the Lower Manhattan Coastal Resiliency Project, a part of New York’s recovery from Superstorm Sandy to create innovative solutions along New York’s waterfront, a complicated network of transportation arteries, water and power infrastructure, and publically accessible parks and paths. AECOM has an integrated group of hydraulic modeling specialists and engineers who collaborate on a national and regional (Florida) basis to discuss emerging technologies and address project technical challenges. We specialize not only in surface water hydraulic models, but also in integrated groundwater – surface water hydrologic and hydraulic models like MIKE SHE-MIKE 11. We take great pride in our model calibration processes and believe that a model has little value if not properly calibrated. Calibration is achieved through extensive field testing, and/or use of telemetric and historical data. The AECOM Team has extensive experience in improving the CRS rating for several communities within Florida. Some of the communities that AECOM has helped include the City of Miami Beach, Sarasota County, and Lee County, to name a few. The team has worked on updating client’s Local Mitigation Strategy Plans, Public Outreach Plan, Land Development Regulation Code, and Floodplain Management Plans to obtain credits, in addition to maintaining information related to the activities listed above.

would divert freshwater inflow from the Naples Bay watershed to rehydrate wetlands and improve flows to Rookery Bay. LAGO, as a subcontractor to Atkins, is responsible for applying the County’s MIKE SHE/MIKE11 model to provide design support and evaluate project benefits. LAGO also was a lead presenter for many of the Public Involvement activities including presentations to the Deputy Director of FDEP. The flows to Naples Bay are currently more than 10 times the predevelopment flow rates. The development that led to that change also contributed to significant degradation of wetlands in the Picayune Strand State Forest and a reduction in flows to Rookery Bay. LAGO is applying an existing integrated surface water/groundwater model to support design and to evaluate the potential increase in hydroperiod in the receiving wetlands as well as the change in discharge to the estuary systems. One key element of the project is to gain the support of the South Florida Water Management District, the Florida Forestry Service and the US Fish and Wildlife Service. LAGO is a key participant in these meetings and was responsible for providing data and results used in the Stakeholder Meetings. MIKEFLOOD model evaluation This project was completed to evaluate the impacts due to construction of a new highway interchange in Thousand Oaks, CA. Earlier modeling efforts completed using the MIKEFLOOD modeling software showed progression of flash flooding during the 100-yr storm event in the area around a recently-built interchange. One of the landowners near the interchange is concerned that the changes introduced by the construction may cause adverse flooding impacts in




scenarios. The team features individuals very familiar with how water resources in the County work, and will be able to leverage that knowledge into the best model reforestation possible. Geosyntec also understands the living nature of the deliverables to be provided with this project. The project flood mapping deliverables will be dynamic in that tools will be developed to assist the County with future projections of coastal changes and groundwater levels. Also, the results of the study will need to be produced and packaged in such a way that the County can take advantage of the potential to gain additional Community Rating System (CRS) credit. During the Geosyntec Team’s work with various municipalities, credit for CRS has been a major consideration and technical results have been developed to support increasing ratings. Interflow Engineering is the lead modeling team assisting the South Florida Water Management District in a project very similar to the County 100-Year Flood Elevation Map and Associated Modeling. As part of the Big Cypress Basin (BCB) Flood Protection Level of Service (LOS) project, Interflow Engineering is conducting design storm simulations (5-year, 10-year, 25-year, and 100-year) of current and future conditions flood levels throughout the Big Cypress Basin using MIKE SHE/MIKE 11.

LAGO then generated GIS-based maps showed the difference in water depths and speed of inundation between the post- and pre- construction conditions. These maps were used to assess the impact of the interchange during the 100-year event.




Experience described in the proposal: The work that the Higgins Team did in Palm Beach County to model alternative futures for setting new rules and regulations for future development was widely accepted by the professional and elected representatives because of the way that our team opened doors of communication with everyone in the affected areas. Feedback from the County, the 298 water districts and the South Florida Water Management District was outstanding. Like the Broward County modeling proposed here, the Palm Beach County area was highly urbanized but also an area of significant future development and improvement.

AECOM developed the Broward County MIKE SHE / MIKE 11 model, which was utilized to compute the 100-year flood elevations for the current FEMA map. It is important to point out that our proposed modeling team was instrumental in Broward County’s initial development of the precursor flood models (NADA, SADA and CADA) and was the only firm that participated in the model update, the results of which were utilized for the creation of DFIRMs for FEMA. AECOM developed the stormwater master plan and associated modeling for the Western and Eastern C-11 Basins in Broward County. AECOM also developed hydrologic and hydraulic models for the North New River and for the Broward County Water Preserve Areas (WPAs). Recently, AECOM supported Broward County with the development of their Local Mitigation Strategy, which included consideration of sea level rise and proposed mitigation activities

DHI and its team members have a thorough knowledge and applicable experience in Broward County’s water resources management system. Having originally developed the first applications of MIKE SHE and MIKE 11 to describe the integrated water resources system within Broward County, the DHI team brings personnel who have been involved with model development and peer review over a period of many years, for this specific model. For the past three years, DHI staff has been engaged in reviewing the current model development and application, and has familiarized with the approaches and level of detail provided by the model. This has given us a level of understanding that will be very useful in the current project delivery, as well as an objective aspect that will ensure a comprehensive range of model improvements are fully considered. DHI and its team members are also focused on the needs and requirements for representing water resources systems in central and

Broward County water resources managers are faced with several unique challenges. These challenges include flat topography with few natural storage areas due to intense development in the eastern third of the County, extremely dry periods and extremely wet periods that stress water resources management system, salt water intrusion into stressed regional groundwater supplies, water supply restrictions from Everglades restoration policies, and sea level rise that has the potential to exacerbate salt water intrusion issues and cause coastal flooding problems. The selected consultant should understand the challenges faced by Broward County and stakeholders in the County and how this flood modeling project interacts with these challenges. Water resources management in the County began with projects to ditch and drain the Everglades to make the land suitable for agriculture and habitation and provide a water supply. These projects enabled the population in the County to grow to

Our Project Manager for this work is former Deputy Director of Operations and Maintenance for the South Florida Water Management District. In this role he spent his time being closely linked up with the municipalities and special districts within Broward County. He was intimately involved with the setting of criteria and operating levels for all of the canal systems within the county and was the one who was called when a variation to operating criteria was needed for local purposes. While at the District, he organized the first inter-agency committee to evaluate climate change and produce a document which highlighted the effects on static system criteria which would have to be modified. As Director of Operations, Mr. Hall was always a key participant with municipal stakeholders, utility companies, communities and neighborhood groups

Demographics Located in Southeast Florida, USA, Broward County was established in 1915 and contains thirty-one municipalities, as well as some unincorporated neighborhoods. With a current population of approximately 1.9 million, Broward County is the second most populated County within the State of Florida. The population is projected to increase by almost 15% in the next 25 years. Geographically, the populated region of Broward County is tucked between the Everglades to the west and the Atlantic Ocean to the east. Connecting these two large aquatic systems are more than 266 miles of primary natural and dredged canals that traverse the county’s urban corridor. Overall, the flows within Broward County’s major canals are highly managed by a series of water control structures and levees operated by the SFWMD that have altered the natural hydroperiods and flows of the South Florida watershed.




including the use of sustainable design concepts to reduce vulnerability. Our project management approach is built on a strong team combining technical expertise and specific knowledge of Broward County’s Water Resources Management. We have selected Guillermo Regalado, PE as our Project Manager. He has worked for AECOM in and for Broward County for more than fifteen (15) years and has designed and managed modeling efforts and floodplain mapping for numerous stormwater related projects. Our Project Manager, Guillermo Regalado, PE, a Broward County resident, will keep in constant contact with the County’s Project Manager and other key County staff as the work progresses. Our management team is located within 30 miles driving distance of the County’s office making it easy to meet in person, as required. We have successfully used the same process on our previous watershed modeling and mapping assignment with Broward County. AECOM Team is intimately familiar with Broward County’s water resources management system, climate change and sea level rise issues and demographics. As provided in the first project description, our team developed the FEMA DFIRM for Broward County based on the results obtained from the MIKE SHE / MIKE 11 modeling. The contract included the refinement and establishment of approximated flood zones, redelineation of existing detailed studies, establishment of new detailed zones, and the creation of a new DFIRMs using new topographic and base map data. In addition to the featured projects, our team maintains significant past and present related experience with Broward County’s water resources

south Florida, with a versatile and experienced team, having worked on recent projects using MIKE SHE and MIKE 11, among other software, in representing flood and stormwater management alternatives throughout the region. This includes recent and ongoing projects with SFWMD, SJWMD, USACE, Everglades National Park and select municipalities. The Team has developed an in-depth awareness and understanding of water resource issues of Florida’s natural and urban systems. Our Team also has an excellent record of performance on a wide range of infrastructure projects for the USACE and Water Management Districts including modeling and analyzing canals, pump stations, levees, embankments, culverts, and related infrastructure. Our expertise will provide efficient and practical understanding for the implementation of control structures and operation scenarios that will affect Broward County’s modeling needs for future conditions. A cross section of recent relevant work, along with responsible team members, is provide in the brief project descriptions below. GIT Consulting has provided a broad range of engineering, design, environmental restoration, hydrologic and hydraulics modeling, and GIS services to clients which include US Department of Interior (DOI), South Florida Water Management District (SFWMD), and US Army Corp of Engineers (USACE).

a present-day population of 1.9 million people. According to data from the U.S. Census Bureau the County grew at a rate of 8.5 percent from 2011 to 2016, with most new residents coming from other countries. In the past, water resources management in the County emphasized extracting water from the Everglades during dry periods as needed to meet demand and drainage canals to prevent flooding during wet periods. Management policies of the past coupled with sea level rise and regional Everglades restoration efforts have impacted the local and regional water resources management of the present. Although water resources management in the County continues to rely on water extracted from the Everglades for water supply and canals to prevent flooding, water resources managers at local and regional levels have adopted and are implementing plans to manage water resources to minimize flood and drought impacts to the population and support Everglades restoration. According to the Broward County-wide Integrated Water Resource Plan (Broward County, 2009) the County is currently implementing the following water resources management initiatives: � Promote conservation to more effectively utilize existing resources � Integrate the secondary canal network for water storage and distribution � Aquifer Storage and Recovery (ASR) to provide storage of wet season rainfall � Wetland rehydration to replenish groundwater, provide storage for aquifer recharge, and improve habitat � Utility sharing to accommodate variable demands in different areas and thus enlarge the water supply to a larger area � Advanced wastewater treatment to

whether the issue was flooding, water shortage or concerns over the future. In addition, several others of our team members were, and are, very active in climate change discussions with their communities.

Water Resources Management As noted in the Broward Water Resources Task Force Report completed in 2012, water resource management in Broward County is provided by a diverse group of agencies including the South Florida Water Management District (SFWMD) at a regional scale as well as water utilities and independent water control districts at a local level. The SFWMD is mainly responsible for water resource planning, water supply permitting, and the operation of an extensive water management system for a service area that includes all or portions of 16 different counties, including Broward County. As part of its operations, the SFWMD maintains a regional network of canals that constitutes a primary drainage system with nine major canals and their corresponding drainage basins: Hillsboro Canal (Florida Department of Environmental Protection [FDEP] Water Body Identification Number [WBID] 3264), C-14 (Cypress Creek Canal WBID 3270), Pompano Canal (WBID 3271), C-13 (Middle River, WBID 3273) Canal, C-12 (Plantation, WBID 3276) Canal, North New River Canal (WBID 3277), C-11 (South New River, WBIDs 3279 and 3281) Canal, C-9 (Snake Creek, WBIDs 3283 and 3284) Canal, and the C-10 (also called Hollywood Canal (WBID 3282, Cooper and Lane 1987). This canal network is critical to effective water resources management and water supply operations in Broward County, with surface waters deliveries from the broader regional system an important part of the hydrologic budget for urban Broward County. Within urban Broward County local drainage/water control districts are responsible for the maintenance and operations of discrete, but

While the regions unique aspects, including its tropical climate and storm exposure, geography, and geology drive much of the risk, the pattern of community development within south Florida, and its integration and management of water environments and drainage, are also very important responses to this setting. DHI and its team members provide experience and perspectives that have been fine-tuned through years of Florida experience, coupled with unique approaches and expertise from working throughout the United States and the world on relevant projects, helping to address climate adaptation challenges. In many cases, this has included advising urban coastal megacities on climate change impact, risk evaluation, and adaptation planning. This combination of local, regional, and global expertise will serve Broward County in its current needs under this proposal, and future requirements in incorporating further climate science assessments and the best available planning guidance to address climate change.

provide an alternative water supply for irrigation and other non-potable uses � Reverse osmosis treatment of brackish water as an alternative water supply The goals of the above initiatives are to ensure groundwater and surface water levels meet the needs of the public and natural systems, prevent saltwater intrusion, provide aquifer recharge, and control flooding. This result of this flood mapping project will assist the County to accomplish its water resources management goals. The updated existing conditions model will provide more accurate existing flood levels. Also, the modeling and mapping of predicted future conditions resulting from future land use changes, sea level rise, more extreme rainfall events and coastal flooding conditions will help the County and other stakeholders adapt management plans to account for future flood conditions.

interconnected surface water management systems that include secondary canals, pumps, controls, and related infrastructure. These systems are directly connected to, and operated in coordination with, the primary canals managed by the SFWMD. The primary drainage system, along with the secondary and tertiary canals, eventually drains eastward to the Intracoastal Waterway when meteorological and hydrological conditions necessitate water management activity, particularly for flood protection. One important exception is the Western C-11 Canal that is normally back pumped (westward) into Water Conservation Area 3B when flood protection measures are necessary. Chapter 5 of the County-wide Integrated Water Resources Plan (IWRP) specifies that Broward County is responsible for optimizing flood protection, water quality, water storage, wetlands sustainability and groundwater recharge, and for implementing its regulatory authority under Chapter 27, Broward County Code of Ordinances. Broward County is also responsible for ensuring that the construction and operation of stormwater management systems comply with all applicable provisions of Chapter 27, as well as with the National Pollution Discharge Elimination System (NPDES-MS4) permits issued by Florida Department of Environmental Protection (FDEP) Sea level rise and climate change issues- Broward County Climate Change Task Force In the face of climate changes and sea level rise, Broward County is also tasked to work with the SFWMD, the eighteen “298” independent water control districts, and local municipalities to investigate and implement the proposed IWRP and Lower East

counties in the U.S. for natural hazard-related financial losses over the last 54 years are in south and central Florida, amounting to nearly $47 billion in losses (Miami-Dade, Broward, Collier, Monroe counties) with all of Florida experiencing over $100 billion in losses in this time period. A global ranking (Hanson et al, 2011, Hallegatte et al, 2016) assessed that Miami had the greatest level of financial vulnerability to climate change and sea level rise, both today, and for the next half century. Broward County carries much of the same setting risk, and very similar water management and drainage challenges, as well as similar demographic components. Broward County’s expected future growth patterns and planning issues are well understood by the project team, especially as they relate to floodplain management, infrastructure and sea level rise. This information, along with guidance from planning agencies and stakeholders, will form the basis for developing appropriate guidelines for future conditions scenarios. Climate Change and Sea Level Rise DHI is a global leader in water resources and coastal analyses and adaptation planning for climate change. DHI has worked with global and regional development banks, and with the various missions of the United Nations in addressing water related risks from climate change, as well as methods and approaches for climate resilience and adaptation. One aspect of DHI’s knowledge dissemination is found in the development of technology and expert guidance materials to guide decision making for Climate Change Response and Adaptation in coastal and inland settings. DHI has recently completed a climate change focused project with the Global Environment Facility and United Nations Environmental Program to deliver

Coast Water Supply Plan. The goal is to improve the timing and reduce the losses of freshwater flows to tide, recharge the Surficial Aquifer System (SAS), provide additional storage to mitigate any impact due to sea level rise, and to adapt to climate change. Some on-going and future action steps to be considered by Broward County regarding sea level rise and climate change include: � Investigate mechanisms for improving stormwater storage � Investigate the impact of freshwater discharges to tide on salinity, coral reefs and water quality � Assess the effects of watershed loss and channelization � Consider rulemaking to increase onsite retention � Consider ocean outfall regulation in the next years and the impact in the canal conveyance, runoff storage and water quality � Coordinate with Water Preserve Area (WPA) projects like the C-11 and C-9 impoundments, seepage management and Site 1 Impoundment. � Add data collection networks and stations for model calibration � Expand traditional surface, groundwater, and chloride stations and more advance stations such as evapotranspiration (ET) stations that can also measure carbon footprints in urban areas. � Collect data and build models to explore effects and design adaptive strategies. Other current issues in Broward County Once the technical Feasibility study and cost-effectiveness of the C-51 Reservoir was completed, Phase 1 of this project is currently under consideration for State and local funding and financing.

He also worked with elected officials and media to inform the public about the process for obtaining Federal Emergency Management Agency (FEMA) accreditation of the Broward portion of the East Coast Protective Levee (ECPL) for FEMA’s Flood Map Modernization Program. Additionally, he defined the South Florida Water Management District’s (SFWMD) role as owner of the ECPL, and communicated the details of the comprehensive ongoing maintenance and operation of the levee. As the SFWMD representative, he was responsible for developing Communication Strategies focusing on elected officials, homeowner associations, civic groups and 298 Districts including the media tools and briefings to educate reporters about the safety and ongoing maintenance of ECPL and a link to Broward County website developed to address this issue. Mr. Lopez was also part of the team in charge of providing documentation showing that a $18M upgrade had been completed by the SFWMD and that the Broward portion of the ECPL (38.3 miles) meets FEMA’s criteria for accreditation for its new FEMA maps as requested by Broward County. Without FEMA certification, the ECPL would not be included in the FEMA flood mapping analysis. Which in turn would could cause flood insurance concerns for residents in the western areas of Palm Beach, Broward, and Miami-Dade counties. The SFWMD presented specific engineering data about the ECPL so that FEMA could provide a “Provisionally Designated Levee” (PAL) designation. PAL status would allow time USACE and District to complete repairs and thereby be recognized as offering a 1.0 percent chance level of flood protection on

The completion of this project allowed the City to capture excess stormwater discharges to the regional system and divert into Prospect Lake, which recharged the City’s wellfield. These projects required coordination and permitting with South Florida Water Management District and Broward County, among other agencies. Brizaga and Irela Bagué have provided outreach and communication services for several project in southeast Florida, including the City of Miami Beach and Key Biscayne, described below. Bayshore Community Public

stormwater assessment. The project included a detailed assessment of flooding (with a County-wide hydrologic and hydraulics model) and water quality conditions, as well as maintenance needs and capital projects to develop funding requirements for a stormwater program. This required translation of technical modeling and stormwater level of service analysis data to stakeholders which included citizens, regulatory agencies, homeowner’s associations, agricultural groups, and environmentalist. Mr. Ellard and Mr. Amstadt worked together similarly during efforts to update floodplains watersheds in Hernando County Florida for SWFWMD. In addition, Geosyntec has provided a variety of services related to creating and maintaining websites as part of public outreach activities. For example, for a Osceola County Florida, Geosyntec assisted with writing and providing content for a community outreach website that the client created and hosted (http://www.osceola.org/agenciesdepartments/ stormwater/shingle-creekbasin. stml) in order to educate the public on the watershed study and solicit feedback on flooding problems and concerns. Team members Taylor Engineering have worked extensively with FEMA projects where a very structured public information and outreach plan of action is implemented. This include stakeholders in Broward County during previous inland flood mapping efforts as well as more recently during their coastal flood mapping work. Team members Interflow have had similar experiences supporting public information and outreach efforts for flood mapping through our several watersheds in Florida. This depth of experience will provide Broward

modernized NFIP maps called Digital Flood Insurance Maps or DFIRMs (44CFR Section 65.10). To promote awareness that SFWMD was taking these steps toward certification, Mr. Lopez coordinated with Broward County and eight communities adjacent to the ECPL to ask for their participation in a letter of agreement. The communities were Weston, Sunrise, Parkland, Coral Springs, Southwest Ranches, Miramar, Tamarac and Pembroke Pines. He also coordinated with SBDD, Coral Springs Improvement District/ Pine Tree WCD, NSID, Plantation Acres WCD. Sunshine WCD, elected officials at the County (County Commissioners) State (Representatives) and Federal level (Representative). Concurrent with the comprehensive levee maintenance and repairs by the SFWMD, required for the ECL certification, Mr. Lopez also assisted Broward County staff with the organization of Public Workshops to inform the public, insurance companies and other stakeholders on the County efforts in the updating of the National Flood Insurance Maps for publication in digital format Broward County Stormwater Initiative From 2006 to 2011 Mr. Lopez coordinated with local partners, including water control districts, municipalities, stormwater utilities and HOAs to identify a series of local and regional stormwater water quality improvement projects within Broward County that could be presented to the Florida State Legislature for funding. The Broward County Initiative was a combination of projects that had multiple benefits and fell within the general goal of restoration and water quality improvements in Broward County and its receiving coastal waters. The project components included: 1.




security, conducting phasing and capital improvement plans, and performing other associated studies.

Outreach, Miami Beach, FL Reference: Susanne Torriente, Assistant City Manager, City of Miami Beach [Vendor Reference submitted for this project] The Brizaga team directed the science communication element of a community outreach program hosted by the City of Miami Beach as part of its “Rising Above” campaign for sea level rise adaptation. To effectively communicate the basis and purpose of the road raising project, tools were developed to help residents visualize their community under nuisance flooding conditions, as well as to understand the primary mechanisms that drive sea level rise. The team developed handouts and take-home documents for homeowners to identify the specific challenges they may face on their own properties and provide actionable guidance regarding measures to protect their homes and property. Additionally, the team authored a report for City officials focused on providing specific elevations and visualization of when the community might begin to experience nuisance flooding based on local sea level rise projections. Vulnerability Assessment & Adaptation Strategies, Key Biscayne, FL Reference: Rumya Sundaram, Community Engagement Coordinator, Key Biscayne Community Foundation Brizaga’s public affairs director, Irela Bagué, served as the lead on the project, tasked to plan, coordinate, conduct and moderate two (2) public town hall style meetings for the Key Biscayne Community Foundation. Brizaga’s founders supported these meetings by participating in a panel and in one-on-one discussions with community stakeholders to present the preliminary findings of a vulnerability assessment performed for the Village, designed to identify specific areas within the neighborhood that may experience

County additional benefit with technical aspects of the community meetings. In addition to support for technical aspects of public outreach, the Geosyntec Team is pleased to feature individuals which will provide additional value to Broward County. Dana Pollitt with ADEPT is extremely familiar with the Broward County environment and will leverage his contact and knowledge to ensure all stakeholders are being identified and encouraged to participate to the highest degree possible. His involvement with local agencies and groups is extensive, including the Broward County Office of Economic and Small Business Development Advisory Board, the Executive Board of the Downtown Fort Lauderdale Transportation Management Association, Vice-chair of the Fort Lauderdale Transportation & Infrastructure Committee, Fort Lauderdale Chamber of Commerce Government Affairs Committee, the City of Fort Lauderdale Executive Airport Advisory Board and the Sustainability Advisory Board. Mr. Pollitt also a member of the Broward League of Cities, and the Fort Lauderdale Chamber of Commerce. In addition to the above, the Team also includes Tommy Strowd as a regional technical resource. As a former South Florida Water Management District Operations, Maintenance & Construction Assistant Executive Director and current Lake Worth Drainage District Operations, Maintenance & Right of Way Director / District Engineer, he has an unmatched knowledge of the interworking’s of southeast Florida’s water resources. This will be advantageous when identifying all stakeholders that may be affected by this project and will provide a

Retrofitting existing stormwater systems (to provide water quality and flood mitigation improvements). 2. Restoring flow to natural systems that supply water to our aquifers. 3. Creating stormwater retention, detention and filter marshes (to remove impurities going to the canals and streams and to improve the hydrology associated with freshwater flows to the estuaries). 4. Restoring the natural systems of our estuaries (to improve shellfish and fish habitat, and associated resource monitoring and assessment). The focus of these projects is to reduce stormwater runoff and to provide hydrologic and water quality improvement to the Everglades Conservation Area through the C-11 Canal and the North New River, as well as coastal area through Hillsboro canal, C-14, C-13 and C-12 canals. These projects are implemented through cooperative partnerships with federal, state, county and city governments, universities, and nonprofit organizations. During these years the Broward County Initiative managed by Mr. Lopez was able to fund more than 20 projects in Broward County in the amount of over $7M dollar. Members of the LAGO Team have conducted public outreach and community meetings with the following: water utilities, municipal stakeholders, local communities, and neighborhood groups. The following table identifies example projects, and for whom public outreach activities were developed (See table page 76)




nuisance flooding in the near future along with timelines of their potential occurrences. The public meetings included a review of resident surveys, flood projections and sea level rise science, and engaged the community members in planning for the next steps in concert with the Village. As part of the project, Brizaga staff prepared the final sea level rise vulnerability assessment and adaptation strategy report for the Village that examined roadway elevations with consideration for local sea level rise projections and outlined possible mitigation strategies.

Geosyntec strives to maintain high productivity, work product excellence and maintain a core value of unsurpassed client service. We closely manage our workload to assure these goals are met without exception and this level of effort will be emulated for all the work performed under contract to the County. Geosyntec has presented below (see page 103) a detailed breakdown of our current workload and the availability of key professional staff to participate on work assignments under this contract. With the local support of our senior management in Geosyntec’s Boca Raton Office, we are confident that future work assignments that are undertaken under this contract will be fully staffed with dedicated resources. The below table (see pages 103 and 104) summarizes our current workload allocations, along with that projected for the next year.

AECOM has managed and produced some of Florida’s largest and most complex projects with the technical expertise and project management talent located in our Coral Gables’ office. Prior to selection of specific staff for our team, we examined the

projects Geosyntec has worked on in the last five years, starting with active projects and followed by completed projects and awarded projects that have yet to start. As can be seen from the length of the table, Geosyntec’s staff has applied consistent resources to complete a wide variety of flood management projects for a variety of clients, and has the ability to move efficiently through concurrent scopes of work and closing out projects meeting client needs. Many of the current project will be finishing in the next few months, where staff resources will be ready to make Broward County a focal point. (see pages 104-107) With a diverse work load of water resources project such as listed above, the primary challenge is in meeting schedule though aggressive staff allocation and resourcing. Geosyntec focuses on strong client communication and strict adherence to deliverables scheduling, meeting this challenge and exceeding client expectations. The success of a project rises and falls with effective project management. Our project management strategy includes effective communication, establishing accurate and accountable internal and external scheduling and cost controls, establishing effective reporting and tracking mechanisms that keep projects on schedule, on budget, and results in high quality deliverables. Geosyntec has an internal project management training program led by a registered project management professional to ensure project managers have the specialized training required to effectively manage projects, control costs, meet schedule milestones, and to ultimately ensure customer

scale to facilitate the reading. This graphic shows that our current projected workload leaves a high level of availability to outstandingly execute this project later this year and into 2018. The graphic is based solely on existing employees and does not fully consider the availability of new employees that may be added as we continue to grow. As depicted in the sketch, LAGO is currently experiencing a level of concurrency consistent with the growth of the company. This has occurred mostly during the last 2 years. However, our workload has never surpassed our capabilities and LAGO has never agreed to a workload that would jeopardize our client expectations and thus, our reputation of excellence in delivering top quality products on budget and schedule. The following is the list of projects corresponding to the projects’ numbers (Project No.) shown in the previous figure. (see pages 77 and 78 for list of projects and table) As a small company, LAGO has a simple organizational structure led and managed by the President and the Vice-President of the firm. Leadership, motivation, communication, knowledge and group dynamics are the basis of LAGO’s management approach. Most of the basis of our management approach are adopted from large-companies and governmental agencies where our current management staff previously served as Senior Project Manager, Principal/Chief Engineer and Senior Scientists (Refer to the Past Performance section for specifics). However, as a firm, LAGO has its own character, vision and mission, and with meticulous attention to our current size and goals, LAGO has been able to




existing and projected workload of each person and confirmed their availability for this assignment. We have determined that they have no obligations, either current or projected, that would prevent them from performing with excellence. AECOM is confident we have the resources necessary to successfully manage this program for the County. AECOM’s mapping, GIS, hydraulic modeling group is accomplished at managing multiple projects concurrently where there is overlap of schedules and activities—both as part of largescale programs and for separate clients. AECOM’s collaboration between offices allows us to access resources worldwide to provide superior team depth and ensure a timely project delivery. As part of our ISO 9001 designation, all AECOM project managers are required to complete rigorous training to provide best-in-industry project management with a focus on effective phasing and scheduling of simultaneous complex projects. AECOM has a long-standing commitment to quality that is part of the company’s legacy. This is demonstrated by our certification in the ISO 9001 quality management standard. Our quality program has been continually updated not only for required ISO elements, but also informed by lessons learned and best practices established by AECOM throughout the world. The company’s water practice is currently certified in all of its offices throughout the United States. Regardless of size, all operating units use this program as a means of standardizing operating requirements to provide a consistent level of quality. AECOM’s mapping, GIS, hydraulic modeling group is accomplished at managing multiple projects concurrently where there is overlap of schedules

satisfaction. Geosyntec considers cost and schedule control critical measures of project success for our clients and our project managers. During each phase of a project we apply our project management and technical skills to control cost and meet schedule milestones. The Project Manager will continually build and reinforce team awareness, so that there is a strong focus on cost and schedule management integrated in the planning and execution of each technical design task and deliverable. To facilitate better communication, Geosyntec utilizes a project SharePoint Site to compile, organize, and communicate all project information with Geosyntec personnel. A secured project website can also be developed to function as a comprehensive repository of project information that can be accessed by the project team and County representatives. In addition, Geosyntec prides itself on its ability to maintain effective communication with our clients. Rarely do projects run exactly as planned, but effective communication can help to avoid those issues from derailing schedule or budget. Regular status reports during the project (i.e., weekly email, monthly memo, etc.) will be critical to keeping the County up to date on project progress and identifying any issues or constraints. We will endeavor to provide open communication channels at all times so the project team and the County are kept continuously apprised of project information or updates. Our Project Manager, Mr. Ellard, will be the focal point for project communication, coordination, and administration for each component of the contract work. This will give the County consistent contact representing the Geosyntec Team.

incorporate important and dynamic elements in our management approach that may distinguish our projects' management quality from our competitors. In this regard, LAGO performs suitable strategic alliances with outside resources, sub-contractors and vendors to assure the highest standards in project completion. At LAGO, Informal discussions at the beginning of each day ensures that the technical challenges are properly addressed and that the work proceeds in a streamlined fashion with no overlap on specific tasks. As the prime consultant, LAGO extends this open and dynamic managerial style to include the other members of the team. On top of our management basis and added elements, LAGO ensures its quality standards, by adhering our quality control to the following values: � Ethical behavior, integrity, confidentiality and discretion; � Exceptional performance coupled with detailed and accurate reporting; � Outstanding professional, keen analytical attention to details, diligent and fair; � Independent judgment, free from bias and conflict of interest; � Objective approach to ensure the results and conclusions are defensible and based only on the QC process. Typical challenges LAGO has faced and will continue to face include: � Size limitations. As a small firm, it is a challenge to gain recognition in a highly competitive market. LAGO continues to grow our revenues and add staff. On projects such as this one, we are ideally suited to execute the work given our background and project experience. � Documents/Reports. Without a support staff, LAGO personnel take personal responsibility for development of documents and materials to reach technical and




and activities—both as part of large-scale programs and for separate clients. One of the advantages of being such a large firm with great depth of resources is the ability to accept new projects while honoring our commitments to our existing ones. We have also proposed a team of outstanding subconsultants that have solid resources as well. Monitoring Project Progress – During the course of the work, we will hold regularly scheduled technical briefings for County staff to review progress, direction, and project objectives. This will allow for correction of the direction of any task during its progress. Deliverables – As project deliverables are prepared, they will receive a formal, documented QA/QC review by qualified AECOM team staff. Following this QA/QC, documents will be provided to the County for review and comment prior to finalizing the deliverable. Our team is very familiar with submittals tracking and review from our experience on large and complex projects. We have successfully utilized spreadsheets for tracking materials sampling and testing information, shop drawings, and materials certifications.

non-technical audiences. To date, our staff have risen to this professional writing challenge with lauded success. � Data availability. From a purely modeling perspective, the limitations and uncertainty in available/relevant data poses a risk in completing fully defensible analyses. This issue is continually and successfully addressed thanks to our staff’s previous projects experiences and qualifications. � Project Timetables/Scheduling. This issue arises often and seemingly during the data collection stage of a project. Typically, this is cleverly managed by scheduling tasks such that readily available and most useful data is prioritized in the collection task. It is also important to foresee potential delaying events and plan accordingly, or it is necessary to modify our approach, in communication with our client, to complete the project within schedule, budget and with total client satisfaction. � Scope Modifications. As with any firm, we have to be aware of the effect that scope modifications can have on our schedule and budget. As a company, we are known for adding value to our work. We have found that the best way to address schedule and budget issues associated with scope modifications is by defining a clear list of deliverables and schedule on the front end and then addressing any needed modifications through frequent and open communication with our clients. � Technical and administrative matters have usually demanded exceptional capabilities and multidisciplinary teaming arrangements. The fact that most members of our team have a long history of ethical performance and have worked together successfully in the past, has made us a solid force to solve technical challenges such as: Inadequacy of available




models/software to some specifics application for the project, Limited quantity/quality of data relevant to a project, Inconsistency of results with previous studies/works and client expectations, Unforeseen need of additional technical disciplines, etc. Under this managerial approach LAGO has successfully completed numerous projects, on budget, on schedule, and with a sustained reputation of excellence, and this has resulted in a sustained trust of well stablished companies, governmental entities and federal agencies on our firm’s capabilities to support them in their challenging mission and goals. LAGO plans to continue working with the same vision and dedication.
