<br />Statement of Qualifications <br /> <br />RELEVANT <br />PROJECT <br />EXPERIENCE <br /> <br />Lower First Creek Flood Hazard Area Deline~ltion and Outfall <br />Urban Drainage and Flood Control District, Adams County, <br />Commerce City <br /> <br />Turner Collie and Braden is updating the hydrology and flood hazard <br />area delineation (FHAD) for the Lower First Creek, from the South <br />Platte River to 96th Avenue. The watershed is approximately 26 miles <br />long, encompassing 47 square miles. The lower and middle portions <br />of the watershed are rapidly developing. In 1998 the hydrology and <br />masterplan for the middle portion of the watershed was updated to <br />reflect current development conditions. Th(~ lower watershed <br />delineation is being updated to incorporate the changed upstream <br />conditions and current development of the lower watershed. When <br />completed, the FHAD will be consistent with CWCB's rules and <br />regulations. <br />Year Completed: In progress <br /> <br />FEMA Flood Insurance Study <br />FEMA, Routt County, Steamboat Springs <br /> <br />TC&B is completing hydrologic and hydraulic analysis of 54 stream <br />miles. The hydrologic analysis included strl~am gage analysis and <br />regional linear regression analysis. The 10-, 50-, 100- and 500-year <br />water surface profiles are being developed. The 1 DO-year tloodplain <br />and floodway boundaries will be provided to FEMA in a digital GIS <br />format <br />Year Completed: In Progress <br /> <br />Green's Landing Letter of Map Revisions <br />Friendswood Development Co. <br /> <br />TC&B conducted a detailed hydrologic and hydraulic analysis with <br />results serving as documentation to request a Letter of Map Revision <br />(LOMR) for Harris County (Texas) Flood Control District (HCFCD). <br />The request involved the removal of the 228-acre Greens Landing <br />Phase I development from the I DO-year floodplain and tloodway <br />based on the construction of on-site drainagl~ facilities and the <br />placement offill. The constructed drainage facilities consisted of two <br />stormwater detention basins and 54-inch cOlTUgated metal pipes <br />(CGMP) outfall structure, a 66-inch CBMP-Arch, an earthen channel <br />with 6-foot bottom width and a reinforced box culvert. The analysis <br />was performed utilizing the Corps HEC-I and HEC- 2 computer <br /> <br />Turner Collie & Braden Inc. <br />
