Request for Proposal

To: Kevin Goff

Clark Engineering

Sioux Falls, SD

To provide engineered documentation of flooding effects at Elmen Acres Subdivision and to

develop a scope of work for a project to mitigate adverse flooding effects to property along

Spring Creek Tributary and Spring Creek and to provide support necessary to formulation of an

effective Benefit Cost Analysis and subsequent Mitigation grant proposal in January of 2011.

1. Spring Creek Tributary at Elmen Acres Flood Elevation determination and

2. Spring Creek Tributary and Spring Creek Mitigation Project Scope of Work:

Existing Floodplain and Base Flood Elevations: Determine overflow from Spring Creek Tributary

into Elmen Acres Basin and determine base flood elevations. Collect lowest adjacent grades

for 46 affected structures to determine impact to structures. (This study is required to lift our

current building restrictions and determine appropriate levels of insurance. It is also

prerequisite to determine the need for and sizes for any changes to culverts.) (Clark Eng.)

Mitigation Project Scope of Work: Develop preliminary project plans and costs for culvert and

channel size changes, excavation and installation, and possible detention along Spring Creek

Tributary and Spring Creek from approximately ¼ mile West of Highway 11 to the Big Sioux

River. Evaluate alternatives and options necessary for an effective mitigation project with at

least a 1:1 benefit to cost ratio and compliance with SDCL drainage requirements. Completed

scope shall comply with FEMA Benefit Cost Analysis requirements. (Clark Eng.)

Benefit Cost Analysis: Estimate potential damages from several flooding events within the study

area. Collect and produce documentation of costs associated with damage to structures

(including contents), loss of function to roads, displacement, rental or loss of income and

Emergency Mgt costs to calculate comparison with estimated project costs. (Lincoln Co.)

Project Grant Application: Prepare grant application; attach documentation (benefit cost analysis,

project scope of work w/narrative, existing floodplain and flood elevations), review, submit.

upon award of grant; final design, construction plans and specs, permitting, bidding,

reporting, records will commence. (Lincoln Co.)

Project Grant Submission: January 1, 2011 Earliest grant distribution: October 2011

Requirements for Mitigation Project Grant Funding

• The Existing Floodplain and Elevation are needed to compare with structure elevations to

show the location and amount of damages expected. These amounts are compared to project costs

to determine the benefit of doing a project. All location and elevation information must be verified

by certified engineer and surveyor

• A Project Scope of Work is a required element of Benefit Cost Analysis. It will thoroughly

describe the project and estimate all direct and indirect project costs. Additional narrative may be

included to justify the project or point out extenuating circumstances such as extensive urban growth

impacts contributing to the need for the project

• A Benefit Cost Analysis is necessary to apply for a Project Grant. FEMA provides computer

software that uses historical flooding events and FEMA standard values to estimate damages

(including contents, loss of function, displacement, rental or loss of income, casualties and

emergency management costs) compared to project costs to calculate Benefit to Cost ratios. The

Benefit to Cost Ratio of a proposed project must show benefits to be greater than project costs in

order to be approved for funding.

• A Hazard Mitigation Grant Program Project Grant application must include the existing

floodplain and elevations, the Project Scope of Work with proposed floodplain and elevations and a

Benefit Cost Analysis, together with all support documentation and showing a ratio of at least 1:1.

The State Hazard Mitigation Officer will review the application before forwarding it to a state board

for approval. It is then sent to FEMA for final review and determination.

• Funding may be awarded upon approval of the grant application by FEMA but may not be

dispersed until our Pre-Disaster Mitigation Plan has been completed. Projects must be listed in the

plan in order to receive funding. The estimated completion of our Pre-Disaster Mitigation Plan is

October of 2011.

• Local match of the grant amount is 25% and may be In-kind contributions. Pre-award costs

associated with development of an effective Benefit Cost analysis may be counted toward the

required 25% local match In-Kind contributions for awarded grants.

• Final design for construction and permitting may commence upon award and dispersement of

funding. The earliest possible timeframe for groundwork to begin would be Spring of 2012.

Construction progress is documented with periodical progress reporting and a final report.

• All counties in the State of South Dakota are eligible to apply for assistance under the Hazard

Mitigation Grant Program.
