Hazus Modernization, Phase 1 Overview

Task 1: Hazus 2.2 Released on January 12, 2015• ArcGIS 10.2.2 and Windows 8 compatibility• Incorporates Census 2010

Task 2: Hazus 2.2 (SP1) Released May 18•Dasymetric General Building Stock implementation• Study region aggregation at custom jurisdiction or neighborhood levels

Task 3: Hazus 3.0 Released November 16, 2015•Re-architecture and source code update• Replace personal Geo-Databases (pGDB) • Replace VB6 and COM architecture with .NET (C#) in flood module• Incorporation of BCA depth damage functions

Task 4: Proofs of Concept (no software changes)•Feasibility of NFHL data integration with Hazus Level 1

hazard determination for 1% and 0.2% flood risk • Performing building and economic AAL using a combination of NFHL and Hazus flood

return periods

8

Phase 1: Task 3 – Released November 16, 20151. Architectural Focus Areas

•Migration of current database structure from Access (.mdb) and Personal Geodatabase (pGDB) format to SQL Spatial

•Updated SQL-compatible version of CDMS•Migration of VB6 code in flood model to C# and .NET•CDMS update to address the new data format

2. Functional Enhancements•Benefit Cost Analysis Re-engineering (BCAR) and Hazus Flood Model depth-damage functions

•FEMA BCA depth-damage functions for mitigation investment decisions have been better aligned with Hazus flood depth-damage functions.

Phase 1: Task 3 – Other items of note

3. Discovered/fixed defectsFoundation-type latent defect was discovered and fixed

•When updating DDF functions, an issue was discovered with how foundation types are handled, resulting in incorrect results for certain types.

Repair of several major defects in block-level aggregation and the flood and hurricane models

•Interpolated return period calculations issue affected hydrology statistics (level 1 riverine analysis)•Field problem that wouldn’t let you do a return period for entire state for hurricane analysis

DEM download changes addressed

Replacement of Personal GeoDatabases (pGDB) Currently default state data (spatial as well as attribute data) is delivered in pGDBs

Problem pGDBs are MS Access databases with significant size and performance constraints. For replacement of pGDBs, the following options have been evaluated:

•ESRI File GeoDatabase•Relational database with spatial extension (SQL Server Express, to be specific)•Open-source spatial databases: SpatiaLite and PostGIS

Solution SQL Server Express (with spatial option) was chosen as the replacement for pGDBs Version: 2008 R2 (the same version currently used in Hazus study region creation); Spatial data will be stored as the Geometry type in SQL Server A few small pGDB databases will remain for intermediate steps to maintain performance

Future Considerations Will migrate to SQL Server 2014 in Phase II – 2016

11

Replacement of DTS Packages

DTS is an ETL (extract, transform, load) tool from Microsoft Currently, DTS packages are used to copy and aggregate data from default state

databases (MS Access pGDBs) to SQLServer Express databases The primary reason why DTS is used today in Hazus is that data resides in two different

database platforms• Default state data (attributes and spatial) in MS Access personal Geo-Databases

(pGDB) • Study region/final results attribute data in SQL Server Express

Problem Microsoft has deprecated DTS which is not available in SQLServer Express editionSolution MS Access-based pGDBs are replaced with SQL Server Express, Hazus will be using a single

database platform for source data and Study region/final results New custom component(s) will be developed to replace functionality currently provided

through DTS

12

Replacement of VB6 Code with .NET (C#)Problem VB6 is outdated and needs to be replaced Hazus Flood module is largely dependent on VB6

Solution .NET Framework, Development IDE:

•The latest version of .Net Framework (4.5) will be used Impact on other modules besides Flood:

•User interface looks and functions similar to as it has in the past Dependency on ArcObjects (lower-level API)

• As recommended by ESRI, higher level API- GeoProcessing Tools (GP Tools) will be used (instead of ArcObjects), as applicable

Functional changes – State Datasets

10

Hazus 3.0 will offer two significant changes to the state datasets:

1. The HAZUS data download page will no longer offer separate data packaging for the two types of data.

•State data downloads will be a single executable zip file containing both homogeneous and dasymetric datasets.

2. Dasymetric dataset is now the default for analysis•All study regions will be created (aggregated) using the homogeneous data,

however in Hazus Flood, dasymetric data will be used when analysis is performed. If desired, flood analysis using homogeneous data can be done with some data manipulations

•Aggregation and analysis for the Earthquake and Hurricane model will use homogeneous data only. These models aggregate at the census tract level and therefore do not make use of the dasymetric census blocks.

Methodology Behind the Changes

14

In order to increase the accuracy with which structures are placed, the Hazus census block polygons have been clipped to areas known to be urbanized by the USACE Flood Impact Assessment (FIA) Team. The goal of the dasymetric data is to remove areas of the block where

structures are not expected to be located, such as areas covered permanently by water and wetlands

•The LULC product overview and accuracy is described here:http://pubs.usgs.gov/fs/2012/3020/fs2012-3020.pdf and can vary by regional geography and specific class type.

• The data used for clipping is provided by the NLCD obtained in 2011 andprepared by the USGS and posted in 2014 at http://www.mrlc.gov/.• Serves as the definitive Landsat-based, 30-meter resolution, land cover

database for the Nation.

What are the major differences?

The main difference between the datasets is the distribution of exposure within a given census block.

Homogeneous: assumes an even (homogeneous) distribution of exposure across a single census block.

• Hazus-MH has historically used homogeneous Census data (uniformly distributed within census blocks) for study region development and analysis.

• Using this data for level 1 analysis, may lead to an over-estimation of losses, though overestimation is not solely caused by homogeneous data.

• These blocks may sometimes cover uninhabited lands, or have few or no structures. For example, a census block may cover a rural area that includes a farmhouse, fields, and roadways.

• This can be inaccurate, as the placement of structures within a given census block are typically clustered due to topography, road networks, and zoning laws.

15

What are the major differences? (Con’t)

Dasymetric: assumes exposure only exists within areas which satellite and land-use data confirm as a built environment.

• Hazus Level 1 loss estimates can be significantly improved by employing dasymetric mapping techniques to constrain Census population data to locations based on the NLCD.

• Users will find areas outside the Land Use/Land Cover (LULC) determined with structures, likely due to either more recent development, or where the automated LULC determinations missed development.

• Hazus dasymetric inventory data represents a significant improvement over the use of Census block or tract-level data in most locations, particularly when site-specific data is unavailable or coarser resolution of loss estimation is preferred.

• The Dasymetric dataset does not serve as a complete replacement of the needfor site specific data enhancements from local datasets.

Testing Results

19

As expected, losses aregenerally less, especially in rural areas and formore minor flooding.This is expected since theriparian and wetlandsareas, including thecoastal Florida examplesbelow, have beenremoved from the losscalculation.

Differences Illustrated

20

When do I use each type?

21

Dasymetric data is the recommended dataset for Level 1 analysis, but users may have reasons to use the homogeneous blocks for analysis:

•User-defined facilities (UDFs) are being included in the analysis, and one ormore of the facilities falls outside of the dasymetric census block boundaries

•User is conducting an inventory update and identify that new development has occurred on previously undeveloped land as reflected by the 2014 era NLCD data. In such a case, the user would need to manually edit or switch the datasets

•This process document will be shared, following FEMA HQ approval The user will be responsible for identifying which dataset most

accurately matches their jurisdiction’s development pattern for current or future conditions.

• Use aerial imagery, local building dataset and compare to both the Homogenous and Dasymetric datasets

What will I need to do to get the new version of Hazus downloaded?

Users of any older Hazus versions will need to uninstall Hazus on their computers. HAZUS 3.0 is available for download on the Hazus page on the Map Service Center.

•Users are no longer able to download Hazus-MH 2.2 from the MSC. If you would like to request an older version of Hazus, please contact the FEMA Map Information eXchange

Check out the Download Tutorial and Quick Reference Guide on the FEMA Document Library and the Getting Started Guide, also available in the Document Library.

•Note: although the container may say 2.1 manuals, these are the most recent versions and can be used with more recent versions of Hazus.

When to Upgrade•It is recommended that users do not download Hazus-MH 3.0 if they are in the

middle of a project. Studies with regions that cannot be easily re-built should be completed on the current version of Hazus-MH prior to downloading the new software.

22

Can I preserve my study regions developed in an older version of Hazus?

Users wishing to preserve their study regions and transfer them to Hazus 3.0 may do so, but only if they are operating on the most recent version of Hazus (2.2 SP01).

•They will be able to follow the steps outlined in the Getting Started Guide to extract their study regions in Hazus 2.2 SP01 and then upload them into Hazus3.0 once it is downloaded.

•Users that are operating on a version of Hazus older than 2.2 SP01 will not be able to extract their study regions and upload to Hazus 3.0 due to major underlying changes occurring in this release

Changes in the Spatial Analyst Tool•As a result of changes made to the Spatial Analyst Tool in ArcGIS, some minor

modifications to the Hazus Core of Hydraulics model were necessary. This resulted in very slight changes in loss estimations in some flood analyses as compared to previous versions of Hazus-MH.

23

Hazus 3.0 Compatibility

Windows and ArcGIS•Hazus-MH 3.0 is compatible with ArcGIS 10.2.2.

•Other versions of ArcGIS is not supported. •Hazus-MH-3.0 is certified for Windows 7, 8, and 8.1.

•Support for Windows XP has been discontinued.

Census Data • Hazus-MH 3.0 release will operate with 2010 Census data, which was

introduced with the release of Hazus-MH 2.2. If users are using a version of Hazus older than 2.2, which operate with 2000 census data, they will not be able to download any of the older data sets from the MSC.

For questions or issues, feel free to contact the Hazus Help Desk at helpdesk@support.hazus.us.
