Or i f f i n On behalf of Mr. Bruce Birdsong, owner of a 5-acre tract on DeForest Road in the City of Coppell, 1 am submitting the enclosed ., f loodplain analysis and supporting information for your review. Mr. Birdsong plans to build a single-family residence on the southern portion of his lot and is requesting a Floodplain Development _ Permit and a Corridor Development Certificate from the City of Coppell. The City's assistance will also be needed in requesting a Conditional Letter of Map Revision from FEMA. Mr. Birdsong's tract is located at 844 DeForest Road, and lies within the 100-year floodplain limits of Denton Creek and the SPF floodplain limits of the Elm Fork / Trinity River. The information ,_ in this report shows that the floodplain fill as proposed by Mr. Birdsong will comply with all applicable ordinances of the City of Coppell.

City Engineer ,~ C i ty of Coppe l l 255 Parkway Blvd. Coppell, Texas 75019 ~' Re: Birdsong Residence Floodplain Reclamation on Denton Creek Dear Ken: I had a lengthy conversation the other day with Jack Quarles (from FEMA' s Denton office ) about submi tta 1 i terns for the Birdsong tract . ,~ He confirmed that the TOD forms (the short ones) are appropriate since the project is a single residence outside of the floodway. He also said that they don't need to see a hydraulic analysis for the same reason. Regarding a metes and bounds description, the one contained in the report should not go to FEMA since it includes area that will not .- be f i 1 1 ed as part of th i s app 1 i cat i on : The i of ormat i on they get should refer only to the house pad. I think that the Grading/Erosion Control Plan might be sufficient to describe the fill area. If not, I can provide a metes and bounds description of the house footprint.

Cross section 193+30 of the effective Denton Creek model passes through the project area. (Please see Project Area Map exhibit.) ^~ The 100-year water surface elevation of Denton Creek at this point is 452.25'. ,_ The project site is also in the alignment of cross section 1051+67 of the Elm Fork model. This cross section, however, was truncated 520' east of the site to exclude the Denton Creek conveyance from the Elm Fork mode 1 . The 100-year and SPF e 1 suet ions of the Elm Fork at the site are 451.47 and 453.67, respectively. A representative of the Corps of Engineers office in Ft. Worth has -~ inspected the project area and determined that no wetlands exist on the site. A letter and sketch from the Corps is included in the exhibit portion of this report. The elevations in the right overbank of section 193+30 of the effective model did not match the City of Coppell's aerial topographic maps, which represent the most accurate topographic data for this area. Therefore, a revised existing conditions model using the City maps was developed before the proposed conditions were analyzed. .. Proposed Improvements The proposed improvements at the project site consist of creating a raised building pad for a single-family residence and a driveway. The proposed finished floor elevation of the house wi 11 be 454.25' . The natural ground elevation at the house site is about 450.2'. Since there are numerous trees are located on the site, no additional fill will be added other than that needed for the house pad and driveway. A grading plan included as an exhibit in this "- report shows the proposed grades for the house pad and driveway. The Denton Creek proposed conditions model shows a proposed right bank encroachment at station 6820, which would represent reclamation well beyond the proposed house pad and driveway. This represents a possible future reclamation scenario that would ... require p 1 ans for f 1 ood storage rep 1 acement i n addition to that being proposed now, The present application includes mitigation only for the flood storage loss caused by the proposed house pad ._ and driveway. Though the encroachment in the proposed conditions computer model represents a much larger area than that to be reclaimed, no ^' increase in water surface elevation or channel velocity resulted. Flood Storage Loss The Denton Creek hydraulic includes the project site as flood w. storage area for the 100-year flood. The drainage area of Denton Creek exceeds 100 square miles, therefore, the storage reduction limits for the 100-year and SPF are OAS and SAS, respectively. The proposed fill would reduce the Denton Creek 100-year flood storage '- by 3. 1AS. Since the total flood storage for the SPF is much greater than that for the 100-year flood, the percent of SPF storage reduction would be much less than 3.1~. The effect on the 100-year storage will be mitigated by using on-site soil for fill. Calculations of flood storage loss are included in the exhibit to this report titled "Hydraulic/Hydrologic Summary." Though the site is also subject to flooding by the Eim Fork, the most recent computer model does not include this area for flood storage or conveyance. Therefore, adding fill would not impact the Elm Fork model. ..~ Equal Conveyance The usual purpose for analyzing an equal conveyance loss scenario _ is to ensure that a property owner on the opposite bank can also reclaim a portion of the f loodplain. Since the left overbank of Denton Creek has already been reclaimed with a levee, this requirement should not be necessary. Erosion Control The areas to be disturbed include the proposed house pad, the driveway, and a small area north of the house where material will be excavated for the pad, The total disturbed area will be less '-' than an acre, and is several hundred feet from a swale or waterway. Any soil washed from these areas would be intercepted by the existing vegetation surrounding the area and could not enter a waterway. The recommended plan to prevent erosion is to maintain a 15' buffer of undisturbed vegetation along the perimeter of the construction area. In the event that sediment does begin to leave ^, the site and is not intercepted by the buffer, a straw bale dike will be erected and maintained along the east property line and downstream of the disturbed areas. .., Conclusion Included in the exhibits of this report are a hydraulic summary .- table and computer printouts from the hydraulic analysis. This information shows that the proposed improvements have a negligible impact on the Denton Creek and Elm Fork waterways. It is requested, „~ therefore, that the City of Coppell approve Mr. Birdsong's application to construct the improvements as shown on the enclosed grading plan. It is also requested that the City of Coppell grant a Corridor Development Certificate for this project, as well as provide the necessary signature on the FEMA application. :~ .- Exhibits: ..

Based on this field visit, and other information available to us, it appears that waters of the United States do exist on the site. Therefore, we have delineated these areas on the enclosed map. Department of the Army authorization would be required for the discharge of dredged or fill material into any areas identified as waters of the United States. If you anticipate a discharge, please provide us with a description of the proposed project, including information on any activities in waters of the United States, the type and amount of material (temporary or permanent), if any, to be discharged, the location of such discharges on a suitable map, and plan and cross-section views of the project. -2- This jurisdictional determination is valid for a period of no more than throe years from _ the date of this letter unless new information warrants revision of the delineation before the - expiration date.
