<br /> - - URS Greiner Woodward Clyde <br /> Task 4: Floodplain and Fooodway Identification <br /> Based on post-project condition modeling results, URS will identify 100-yr floodplain <br /> and floodway locations as well as 500-yr water surface elevations for the study area on <br /> hard copies of the study area. The City will be responsible for generating all base maps <br /> ' and developing FEMA work maps using the information provided by URS. The City's <br /> GIS Team will also be responsible for verifying the accuracy of the contour map in <br /> relation to topographic data used in the study. <br /> Task 5: Complete FEMA Application and Documentation <br /> URS will prepare the following LOMR application (MT-2) forms: <br /> 1. Form 1 -the revision requester and community official form <br /> 2. Form 3 -the hydrologic analysis form <br /> 3. Form 4 -the riverine hydraulic analysis form <br /> 4. Form 5 -the bridge/culvert form (one form for each bridge/culvert added or revised) <br /> 5. Form 8 -the levee analyses form <br /> URS will provide all necessary input and output data, computer files, and other <br /> background data required for the submittal. The City will be responsible for producing <br /> all maps and providing required as-built drawings for existing structures in the Lower <br /> Amazon Creek for the submittal. URS will work to help the City to apply for a waiver of <br /> the required FEMA review fee for LOMR application. URS will also prepare a final <br /> report documenting the modeling methodologies, procedures, and results. <br /> Task 6: FEMA Approval Process <br /> FEMA is required to respond to the application within 90 days. The response from <br /> FEMA will either be approval of the LOMR or clarification/request for additional data or <br /> revised data. If necessary, URS will provide clarification of the data or provide <br /> additional data requested by FEMA. If the initial application is approved by FEMA, this <br /> task will not be necessary. <br /> It is difficult to predict the amount of the work involved in responding to the FEMA <br /> approval process. This cost estimate included an allowance for URS to address FEMA's <br /> comments. URS will respond to FEMA's comments and requests up to the limit of the <br /> budget provided in Table 2 for Task 6. <br /> The total cost for the Lower Amazon Creek LOMR study is included in Table 2. This <br /> cost estimate is based on using the HEC-RAS hydraulic model. The total cost is <br /> predicted to increase if either XP-SWMM or UNET is used due to the significant efforts <br /> involved in achieving the required effective tie-in and identifying floodway locations as <br /> shown in Table 1. In addition, significant delay in the FEMA approval process (Task 6) <br /> might be encountered if either XP-SWMM or UNET is used to perform the required <br /> hydraulic analysis. <br /> \\Por2\PROJ-WC1945042na\TASK03011\AMAZOMFEMA\tema.duc 4:08 PM 02/25/W Page 6 <br /> <br />
