Proposed model was created with the fence sections as they exist on the property. Asecond proposed model was created with a proposed earthen swale that mitigates the presence of the fence. June20152DEH Consulting, LTD. 157 Cottonwood HYDROLOGY As requested by City of Coppell, 100-year discharges for Cottonwood Branch developed by the TN&P CLOMR arebased on ultimate watershed conditions and serve as a basis of this flood study. HYDRAULIC DEH Consulting, LTD(DEH) analyzed Cottonwood Branchusing HEC-RAS computer model. The computer program HEC-RAS River Analysis System was developed by the Hydrologic Engineering Center of the U.S. Army Corps of Engineers (Version 4.1.0,January 2010). DEH was provided the CLOMR Post-Project model for Cottonwood Branch. See appendix B for copy of Post-Project model from the CLOMR. Changes were made to the CLOMR "Post-Project" model at various stream locations along 157 Cottonwood Drive to create an "Existing Conditions" model found in Appendix C Some of the changes are as follows: FIS cross-section6710 was copied to create sections 6413, 6423 and 6720 and sections 7213 and 7223 are interpolated sections using FIS section 6710 and 8000 as a basis. One proposed model for the fencing was created by utilizing the existing conditions model and adding obstructions for the fenceat sections 6403,6710, and 7213. A second proposed model was created to add an earthen swale starting at a 8 feet bottom, 4:1 side slopes and ending downstream with 18feet bottom and three feet deep to mitigate the impacts of the fencing. See appendix E for alignment of the proposedearthen swale. Manning’s “n” values were based upon field investigation. For the natural stream channel a value of 0.05was used and for the overbanks, a value of 0.035was assigneddue to the pasture conditionsfor existing and proposed models. Results of the HEC-RAS “Proposed”modelsare found in printout of Appendix D. NCTCOG 2007 topographic mapping provided by City of Coppell and base map from CLOMR, Inc. wereused as a basis of the hydraulic analysis Digital data from FEMA wasusedtomap the existing 1% Annual chance floodplain. See Appendix E for the floodplain work map. June20153DEH Consulting, LTD. 157 Cottonwood RESULTS 100-year floodplain analysis for ultimatewatershed conditions with natural channel conditionsand fencing indicates that there is a rise in the 100-year water surface elevation compared to existing conditions with no fencing. 100-year floodplain analysis for ultimate watershed conditions with natural channel conditions and fencing and proposed earthen swale indicates that there is no rise in the 100-year water surface elevation compared to existing conditions with no fencing. Calculated water surface elevations and velocities for the modelsare found in the table below.
