Introduction O’Brien Engineering, Inc. (OEI) is under contract with The Holmes Builders (Owner) to prepare an application for a Corridor Development Certificate (CDC) for the development of a 54.6-acre tract in Coppell, Texas. The subject tract is located north of Sandy Lake Road, west of the Elm Fork of the Trinity River (Elm Fork), and approximately 2000 feet east of MacArthur Boulevard. Denton Creek flows through the subject tract and drains into Elm Fork approximately 5,400 feet downstream. II. Objectives of This Study The primary objectives of this study are to evaluate the floodplain of Elm Fork in the vicinity of the subject tract to ensure that the proposed development would not increase the design flood water surface elevations or erosive velocities and to ensure that the proposed development would not result in valley storage losses for the 1% annual chance (1% AC) flood and the Standard Project Flood (SPF), greater than 0.0% and 5.0% respectively. III. Hydrologic Analysis No hydrology was developed for this project. The hydraulic model for this project evaluation uses the peak flood flow rates based on future anticipated watershed development for the year 2055. IV. Hydraulic Analysis A. Methodology The floodplain and channel topography for the subject area were obtained from on- the-ground field data surveyed by Kadleck & Associates mapped to one-foot contour interval topography. The topography for limited portions of the floodplain outside of the project site were augmented with the North Central Texas Council of Governments (NCTCOG) 2007 aerial photography mapped to 2-foot contour intervals. The topography for portions of the Denton Creek channel were augmented with topography developed for the Trinity River Corridor Mapping from a 2 1991 aerial survey mapped to 2-foot contour intervals. The hydraulic analysis was conducted using the U.S. Army Corps of Engineers (USACE) water surface profiles computer program, HEC-RAS (version 4.1.0). In addition, the hydraulic model has two sets of geometry data based on high frequency flood flow rates, consisting of the 10% to 1% AC floods and low frequency flood flow rates consisting of the 0.2 % AC and the SPF floods. Channel and overbank reach lengths were digitally measured using AutoDesk’s AutoCAD software. Manning’s roughness coefficients were verified through field reconnaissance with reference to “Guide for Selecting Manning's Roughness Coefficients for Natural Channels and Flood Plains Water- Supply Paper 2339,” by the United States Geological Survey, 1989 and Ven Te Chow, “Open-Channel Hydraulics”. B. Current CDC Model (Base Model) The United States Army Corps of Engineers (USACE) model for Elm Fork of the Trinity River was requested and obtained from USACE. The model is dated January 1, 2014 and was received in March 2016. The data obtained is in HEC-RAS format. The model was input into OEI's database and executed to verify data integrity. C. Revised CDC Model The Base model received from USACE was used as a platform for creating the Revised CDC model through the project area. The Revised CDC model for Elm Fork was established by adding one cross section (97792) in the project vicinity and moving cross section 97178 approximately 180 feet downstream to river station 96997. The profiles of these two sections and section 97919 were updated with the topography data described in the methodology section of this report. Contraction and expansion coefficients used in the model are 0.1 and 0.3 respectively for normal floodplain conditions and 0.3 and 0.5 respectively near constrictions. Downstream reach lengths were updated based on the location of the new cross sections. Manning’s roughness coefficients were entered into the model on the new sections using the horizontal variation method, consistent with the base model. Ineffective flow limits based on contraction of flow due to encroachment of the 3 Sandy Lake Road bridge were maintained based on the USACE workmap produced for the base model and mapping. The model cross section locations are illustrated in Exhibit 2 – Hydraulic Workmap and Exhibit 3 – Site Map (Appendix B). D. Pre-Project Model The purpose of the Pre-Project model is to simulate any man-made changes constructed since development of the base modeling. The Pre-Project model is developed from the Revised Base model as a platform and, therefore, includes corrections and updated topography. For this study, the Pre-Project model for Elm Fork is identical to the Revised Base model as there were no modifications in the project vicinity, since the development of the base modeling. Therefore, no separate Pre-Project model for Elm Fork is included herein. E. Proposed Project Model (With-Project Model) The Pre-Project model was used as a platform to develop the With-Project Conditions model. The With-Project model for Elm Fork represents floodplain modifications, which would result from the proposed development, which includes placement of fill in the right overbank due to the proposed development. The proposed floodplain modifications begin near cross section number 97919 and continue through cross section 93359. Excavation of a pond is proposed on a portion of the subject tract near cross sections 97919 and 97792. Manning’s roughness values were adjusted on cross sections 97919 through 96997 to represent proposed site conditions. Roughness coefficients used in the remainder of the model are identical to those in the Pre-Project model. Blocked obstructions in the right overbanks of cross sections 93940 and 93359 represent fill near the proposed subdivision entrance by Sandy Lake Road. The proposed development is illustrated in Exhibit 4 – Proposed Site Grading Plan (Appendix B). 4 V. Valley Storage Analysis Valley storage for the proposed site was calculated using ESRI’s ArcGIS software (version 10.3). Digital surfaces were generated for the existing topography, the proposed topography, and the pre- and post-project floodwater surface elevations. To determine the pre-project valley storage on the subject property, the existing conditions digital surface was compared to the pre-project 100-year and SPF flood profile surfaces on the Elm Fork. The comparison was made by using the Surface Difference tool available in the ArcGIS 3D Analyst extension. The post-project valley storage on the subject property was determined by the same procedure using the digital surfaces for the post-project grades and the post-project flood profiles. Results of the valley storage calculations are presented in the CDC Application Form (Appendix E). Floodplain fill for the project encompasses the majority of the site in areas designated as sub-divided residential lots and streets. Compensation for this loss in valley storage has been provided by two excavated ponds located on the east side of the subject property and by an excavated peninsular area along Denton Creek near the southeast corner of the project site. The baseline discharge established in the CDC Manual for the Elm Fork is 4000 cfs, which was used in the Revised CDC model for this study to establish the baseline discharge valley storage elevations. The CDC Manual states that, “valley storage below the water surface elevations produced by the baseline discharge shall be considered ineffective, unless a control structure is designed to ensure that the entire volume is available for storage.” The average water surface elevation produced by the baseline discharge in the project vicinity was determined to be 437.8 feet. The proposed south pond will be excavated to an elevation of 435.0 feet. Final construction drawings for the ponds will include a pipe large enough to drain the ponds down to the proposed elevation of 435.0 feet within a reasonable time and will contain a flap gate device attached to the pipe outlet. The flap gate will be designed to prevent flow from small flooding events on Denton Creek into the ponds and reserve the valley storage in the ponds for larger flooding events on the Elm Fork. The proposed north pond will be excavated to an elevation of 430.0 feet. Similar to the south pond, a pipe with a flap 5 gate will be installed to drain the pond to an elevation of 435.0 feet. A pump will be installed to drain the pond to an elevation of 430.0 feet to ensure that the entire design volume is available for valley storage. VI. Operation and Maintenance Summary The proposed project contains a significant amount of modified floodplain represented in the With-Project model. These floodplain modifications will need to be maintained after construction is completed to keep the With-Project model conditions correctly represented on the ground. The majority of the project site was simulated in the With- Project model using the ineffective flow option specifically around the residential sub- divided lots. In this area no maintenance is required to maintain consistency with the model. However, the area surrounding the northern excavated pond will need to be maintained with the appropriate vegetative cover representing the model roughness conditions. In addition, the pump should be maintained routinely. The proposed drainage pipes and flap gates should be inspected and cleaned of any debris on an annual basis and after significant events to ensure proper functionality. VII. Results & Conclusions As required by CDC guidelines, there would be no increases greater than 0.04 feet to the 1% AC flood water surface elevations and no significant increases to the Standard Project Flood water surface elevations when compared to the Pre-Project Conditions. There would be no increases to erosive velocities in the channel nor in the overbanks. Results are summarized in Table 1 and Table 2 for the 1% AC and SPF respectively (Appendix A) and in the CDC Application Form (Appendix E). Hydraulic model outputs (Appendix C) and cross-section comparison plots (Appendix D) have also been included. A digital copy of the hydraulic model is attached (Appendix F). The results from the valley storage computations as referenced in the attached application indicate that there would be no loss in valley storage in the 1% AC flood event and no loss greater than 5.0% in the Standard Project Flood. The project would not result in adverse conditions on Elm Fork of the Trinity River. 6 We trust that the above details and enclosed data will provide the City with sufficient information to review the project and ask that the City of Coppell forward the study to the USACE in order to begin the CDC review process.

I certify that I am knowledgeable of the information contained in this application, and that to the best of my knowledge and belief, this information is true, complete, and accurate. ______________________________________________________________________________________________________ Signature of CDC Applicant or Applicant's Representative ______________________________________________________________________________________________________ Typed Name/Title/Date ______________________________________________________________________________________________________ P.E. License Number and seal/stamp Valley storage for the proposed site was found using ArcGIS 10.3. Digital surfaces of the existing topography, the proposed topography, and the floodwater surface elevations were created. Comparisons were made between the topography and water surface elevations to calculate valley storage. Floodplain fill for the project site encompasses the majority of the site in areas designated as sub-divided residential lots and streets. Compensation for this loss in valley storage has been provided by two excavated ponds located on the east side of the subject property and by an excavated peninsular area along Denton Creek near the southeast corner of the project site.
