Item 6B - Flood Studya F27-MMMM • FloodStudy HTeaOSouthlake, TX October 28, 2021 Introduction This project is approximately 1.3788-acres located at 190 Davis Blvd in Southlake, Texas, as shown in Appendix A — Figure 1. The Project site is currently undeveloped with a Sonic site to the north, single-family residential properties to the east across Davis Blvd., and undeveloped land to the south. Tributary BB-9 flows from north to south along the western side of the property. Per FIRM 48439C0090L, revised March 21, 2019, there is FEMA floodplain (Zone AE) within the Project site. The Project is planned to be developed as an HTeaO commercial property with the construction plans by Bowman Consulting. The topographic survey was performed by Spooner & Associates and dated July 21, 2021. The purpose of the flood study is to use the topographic survey data provided by Spooner & Associates to determine the corrected effective 100-year floodplain within the limits of the Project site. It is also to determine if the proposed Project will cause any adverse hydrologic impacts to the adjacent properties. It is the intent of the Project for all work to remain outside of the limits of the corrected effective 100-year floodplain of Tributary BB-9. Overall Hydrologic Analysis KCE requested the effective models for Tributary BB-9 from FEMA and received a PDF of the HEC- K output for Tributary BB-9 from lettered cross -sections A-G. In addition, KCE also received the effective models and shapefiles from the upstream LOMR 19-06-1227P by Boyd Hydrology, PLLC which became effective 4/27/2020. Since FEMA did not provide KCE with any effective hydrologic models for the watershed of Tributary BB-9, KCE instead created a HEC-HMS model to determine if the proposed Project would have an adverse hydrologic impact to other properties. KCE used the onsite topographic survey data provided by Spooner & Associates as well as the 2019 USGS lidar contour data to delineate the watershed to the downstream side of the Project site. Based on the delineations by KCE, the watershed to the downstream side of the Project is approximately 808-acres, so KCE selected the SCS Unit Hydrograph method as the most appropriate method to determine the peak discharges at the junctions. Refer to Appendix A — Figure 2 for the drainage area map. The SCS curve number (CN) represents the runoff potential of a given area with the higher the CN, the greater the runoff potential. The curve numbers are determined based on hydrologic soil type and land use. For this project, KCE determined the CN based on the hydrologic soils type from the USDA Web Soil Survey and the existing land use from the NCTCOG land use data, edited to reflect more recent developments. Refer to Appendix A — Figure 2 for the existing land uses, and the soils map is shown in Appendix A — Figure 3. r h Flood Study E HTeaO — Southlake, TX October 28, 2021 The time of concentration is defined as the time required for water to flow from the most hydraulically remote point of the basin to the design point of interest. The path of travel is divided into sheet flow, shallow concentrated flow, and open channel flow (or closed storm system flow). The times of concentration for the subbasins were calculated based on the SCS publication Technical Release 55 (TR-55) standard engineering practices. The flowpaths used are shown in Appendix A — Figure 2. The detailed time of concentration calculations are shown in Appendix C. Based on TR-55, the watershed lag time was calculated at 60% of the total time of concentration for each drainage basin. The watershed lag time is the time from the center of mass of excess rainfall to the peak rate of storm water runoff. Tables 1 and 2 shows the existing and proposed hydrologic parameters, respectively. Table 1— Existing Hydrologic Parameters Existing Sub Basin DA (acres) DA (Sq.Mi.)

Table 3 below shows the results summary. r h Flood Study E HTeaO — Southlake, TX October 28, 2021 Table 3 — Results Summary Hydrologic 100-yr Peak Discharge (cfs) 2-yr Peak Discharge (cfs) Junction Existing Proposed Prop - Exist Existing Proposed Prop - Exist OS-1 2,547 2,547 0 873 873 0 A 5 11 5 1 5 4 Junction-1 2,548 2,548 0 873 1 873 0 Based on the results of the HEC-HMS model, although there is a slight increase in peak runoff for subbasin A due to the proposed development, the net impact at the downstream junction, Junction-1, is no change to the peak discharge for either flow event. Therefore, the proposed Project should be able to develop as planned with no detention. Per the effective FIS data, the effective 100-year peak discharge at the corporate limits of the City of Southlake approximately 3,000-ft downstream of the Project site is 2,650 cfs, so the watershed peak discharge of 2,548 cfs at Junction-1 is reasonable. Overall Hydraulic Analysis KCE requested the effective models for Tributary BB-9 from FEMA and received a PDF of the HEC- K output for Tributary BB-9 from lettered cross -sections A-G. In addition, KCE also received the effective models and shapefiles from the upstream LOMR 19-06-1227P by Boyd Hydrology, PLLC which became effective 4/27/2020. After opening the provided models and shapefiles from FEMA, KCE determined that the current effective FEMA floodplain through the Project site appears to have been moved or shifted from the actual location of the creek. Since the provided models are not in the correct location, KCE created a hydraulic model of Tributary BB-9 through the Project site. KCE used a combination of the onsite topographic survey data provided by Spooner & Associates within the Project boundaries and the USGS 2019 contour data for the offsite portions to create an existing terrain. KCE determined the Manning's n-values based on aerial images of the site and from the effective model. The downstream limits were set as a known water surface elevations from the FIS effective lettered cross-section E. The United States Army Corps of Engineers HEC-RAS (version 6.0) program was used to calculate the WSEL and velocity within the limits of the study. Table 4 below displays the HEC-RAS results from the FIS effective 100-year peak discharges through the Project site. The corrected existing floodplain is shown in Appendix A — Figure 4. Refer to Appendix D for the HEC-RAS profile and cross -sections for the FEMA storm events for Tributary BB-9. r h Flood Study E HTeaO — Southlake, TX October 28, 2021 Table 4 —100-Year HEC-RAS Results Tributary 1313-9 100-yr Results River Station Q Total (cfs) Existing WSEL (ft) Velocity (fps) Valley Storage (acre-ft) 7499 2650 639.91 3.82 16.25 7305 2650 639.24 5.49 12.7 7222 2650 638.94 6.17 11.28 7091 2650 638.28 6.82 9.16 6928 2650 637.53 6.35 6.61 6774 2650 636.78 6.26 4.24 6674 2650 636.35 5.37 2.49 6490 2650 635.75 5.31 0 Once KCE provided Bowman Consulting with the corrected existing 100-year floodplain through the Project site, the proposed site and grading plans were adjusted to remain outside of the 100- year floodplain. The FFE of the building was set at 651.00 which is more than 11-ft above the adjacent 100-year WSEL of 639.24. ��r FloodStudy HTeaOSouthlake, TX October 28, 2021 Conclusions This flood study was performed to determine if the proposed Project can be constructed as planned without causing an adverse hydrologic or hydraulic impact to other properties per the City of Southlake definition. Based on the results of the hydrologic analysis, there are minor increases in the onsite peak discharge as a result of the Project but the net impact to the watershed is no change to the peak discharge of Tributary BB-9 due to the timing of the contributing hydrographs. KCE delineated the corrected effective 100-year floodplain through the Project site using the effective FIS peak discharges. All proposed onsite improvements were designed by Bowman Consulting to remain outside of the corrected existing 100-year floodplain. The proposed FFE of the onsite building is more than 11-ft above the adjacent 100-year WSEL. Therefore, the Project should be able to be constructed as planned with no onsite detention and no floodplain reclamation. If you have any questions or comments, please feel free to call.
