The scope of work consists of assembling the hydrologic and hydraulic models,compiling the required report/documentation, and completing the Letter of Map Revision (LOMR) application necessary to update the Flood Insurance Rate Map(FIRM). As you know,the regional detention basin has been constructed, and an as-built topographic survey has been completed by the City of Fort Worth,and already provided to us. However,we understand the previously utilized HEC-RAS model has been updated,and we will therefore have to update our previous hydraulic study with this new base model. We anticipate updating the FIRM with reduced floodplain limits along Dry Branch Creek,from E. Belknap Street(SH 377) northward and upstream to NE 28th Street,the regional detention basin.The Base Flood Elevation (BFE)was reduced by approximately 0.5-ft or more within these limits;and we are not proposing to extend the LOMR further downstream (or upstream). This LOMR application will be based upon updated hydrology and hydraulics,and FEMA will therefore require a significant($8,250)submittal review fee;and, as discussed,this has not been included as a direct expense within our proposed professional services fee. 3801 William D Tate,Suite 50111 Grapevine,TX 76051 PH:817-2514551)1 FX:817-2514810 TBPE Firm#44,TBPLS Firm#10011300,#10011302,#10194146 engineering J surveying I landscape Dry Branch Creek Regional Detention March 30, 2018 Page 2 of 3 Our efforts provide for updating the previously completed hydraulic model,compiling the necessary hydrologic and hydraulic data and reports,preparing the LOMR application and assisting with the submittal process as follows: Assemble LOMB and Submit to City $13,000...submit to SWM and Floodplain Management Submit LOMR,Address Comments& Resubmit 7,580...coordinated w/Floodplain Management Total for Professional Services $20,580 A detailed breakdown of these fees, in the form of the city's Level of Effort Spreadsheet, is enclosed for your reference.This is a total stipulated amount of Twenty Thousand Five Hundred and Eight($20,580) Dollars; and includes direct expenses(i.e. reproduction, courier,travel,etc.), but not FEMA's LOMR fee. Services not included in the above outlined scope of work consist of, but are not limited to, revising the previously completed hydrologic(HMS) model,extending the LOMR beyond the river reach described above, addressing multiple review cycles with new comments. All work will be performed in accordance with standard industry practices. Additional services, if required/requested and pre-approved,will be provided on an hourly basis and at our standard billing rates. If the scope of services and fee structure meets with your approval,then please sign below,signifying your acceptance,and return a copy for our files.We will consider receipt of this signed agreement as our notice to proceed.
