CDC Information Morrlson Hydrology Engineering, ln~ Page -3 Introduction The purpose of this repo~ is to submit tonnation in support of approvals relating to the City of Coppcll Floodplain Management Ordinance, The Federal Emergency Management Agency (FEMA), the Corndot Development Certificate (CDC) process, and the Co~ps of Engineers Clean Water Act Section 404 (Wetlands). The project area is south of Sandy Lake Road, and east ofMcArthur Blvd. and consists of fill in the floodplain with compensating excavation that results in no increase in flood levels and no decrease in flood storage. The project area consists of two general tracts, a 10-acre and 48 acre tract. Both tracts contain some floodplain from the Elm Fork of the Trinity River. City of Coppeil R_equiroments General The City of Coppell through a Floodplain Management Ordinance has specific requirements relating to this projecL The lowest floor of all residential constnwflon must be elevated a minimqln dtwo feet above the Hood Insurance Study (FIS) base flood elevation or one foot above the design base flood elevation, whichever is higher. This report has shown fill one foot above the FIS bose flood; asmnming that residential structures finished floors will be eleva/ed one foot above grade. A check was made to ensure that this elevation is higher than the design flood plus one foot and higher than the current Corps of Engineers study in the area. Hydrologic and Hydraulic Information A copy of the CityWide Storm Water Management Study for the City of Coppell dated January 1991 was obtained (appendix 1). This document provided the design flood elevations used in this study. Table 1 is a comparison between all the flood elevations from sources investigated in this study. The proposed pwject meets or exceeds all the Hoodplain Management Offlinance requirements. I~MA lnfornlation Them are several sources available to determine the FEMA flood eAevations for the site. They are as follows: 1. Request for Conditional Letter of Map Revision on the Elm Fork of the Trinity River Sandy Lak~ Road Bridge Hydraulic Study, Halif Associates Inc., Dallas, Texas June 1994. 2. Floodplain Hydraulics Study Elm Fork Tri~ty River for Conditional Letter of Map Revision Request 18.9 Acre Sandy Lake Road Property, Nathan D. Mater Inc., Dallas, Texas July 1996. 3. Corps of Engineers HEC-RAS model currently iln~5 ~wi. ew by FEMA. Morrison Hydrology Engineering, Inc. Page -4 FEMA Effective Information In order to decide which model to use as the effective condition conh~ct was made with FEMA' s technical consultant Michacl Baker Jr. Engineers. They agree that the most accurate model would be the Corps HEC-RAS model currently under review. However, this model has not been officially approved and can not be considered the effecflve model at this time. The next most earrent model available is the Floodplain Hydraulics Study Elm Fork Trinity River for Conditional Letter of Map Revision Request 18.9 Acre Sandy Lake Road Property, Nathan D. Maier Inc., Dallas, Texas July 1996. This model was provided from the City of Coppert. This report used the existing condition from this model as the effective FIS model. Hydraulic Information The project area is modeled by all the studies investigated in the same way. It is blocked from flow from the Elm Fork of the Trinity by high ground, This means that it is in an ineffective flow area, and filling Of the site has no impact on the floodplain elevations. The site can be ~led without alteration of the flood elevations or any other impact except flood storage, and this has been addressed by offsetting storage compensation. All required FEMA forms to support a Conditional Letter of Map Revision based on fill are included in appendix 5. CDC Information General The project area consisting of two tracts, one I O-acre tract adjacent to McArthur Road and south of Sandy Lake Road, the other tract is a 48-aere triangular site. Both of these Wacts are shown on the drawing in appendix 7. The project consists of fill in the floodplain with compensating excavation that results in no increase in flood levels and no decrease in flood storage. Hydrologic and Hydraulic Information The two tracts are affected by the flood elevations from the Ell Fork of the Trinity River. However, there elevations are blocked from the actual flow of the river. The area is in an ineffective flow regime and thus has no impact on flood elevations as long as storage levels are not reduced. This means that tilling the tracts has no impact on the flood elevations. SWrage Determinations It is impartant to eftret any lost storage created by filling the tract. This is accomplished by excavating a portion of the TP&L easement on the 48-aere tract. This area is shown on the drawing in appendix 7. In order to determine the storage on the property before and after the proposed project a compu~r model was created by describing cross sections through the area. The results of this analysis are included in appendix 7. Morrlson Hydrolog~ Engineering, Inc. Page Results The project site is in an area that receives floodwaters from the Ell Fork of the Tzinity River, but is isolated fxom the actual flow of the river. Because of this the area can be filled without impact to th~ flood elevations of the river. This report has identified storage mitigation so that there is no net decrease in flood storage. CDC Forms All required forms in support of a CDC approval are included in appendix 7. Summary This report provides information in support of the following approvals: Federal Emergency Management A~ency Conditional Letter of Map Revision based on fill Corridor Development Certificate approvals City Hoodplain Management Ordinance approvals Coordination is continuing with the Corps of Engineers in order to oblain 404 permit approvals.

The computer program HEC-2 Water Surface Profiles developed by the Hydrologic Engineering Center of the COE is used for this purpose (Version 4.6.2; May 1991). The effective FiS multi-profile and floodway models for the Elm Fork were obtained. These HEC-2 models are duplicated as the initial step in this study. The duplicate multi-profile model is provided in Appendix D and the duplicate floodway model in the first part of Appendix G. As shown in the multi-profile model, the peak flow rates for the project segment of the Elm Fork are 24,300 cubic feet per second (cfs) for the 10-year flood, 37,100 cfs for the 50-year, 44,350 cfs for the 100-year and 60,400 cfs for the 500-year flood event. These same discharges are used for all evaluations performed in this study. The duplicate FIS HEC-2 model is modified first to reflect the existing project site conditions. The distance from the main channel to the property located in the right (facing downstream) overbank is determined by scaling from aerial topographic mapping. The ground points within the segment of the cross section representing the project site are replaced with data based on field surveys performed by Nathan D. Maier Consulting Engineers, Inc. (NDM CE) in March 1996. The cross section in the duplicate FIS model located at stream station 9384-10 traverses the Sandy Lake Road Property and is modified as described to represent existing conditions. The next section in the model is located 3760 feet upstream. These modifications result in the existing conditions HEC-2 multi-profile model. The input and output listings for this model are provided in Appendix E. Modifications proposed for the Sandy Lake Road Property consist of earthwork operations only. Fill is to be placed in the western portion of the property to reclaim the area for the ultimate site development. The fill will be placed and compacted to densities acceptable under the FEMA regulations. The fill will extend upward from the bank of Denton Creek along the north side of the property on a 4:1 (H:V) slope to a minimum elevation of 447. On the south side of the property adjacent to Sandy Lake Road, the roadway is to be improved in the near future and additional right of way expansion into the property is planned. The location of the proposed right of way is determined from construction plans obtained from the Dallas County Department of Public Works (County Project No. 91-830, by Sverdrup Corp.; March 1996). The horizontal location of the fight of way is matched by the proposed fill to be placed for this project. The top of fill elevation is also adjusted to match the grades proposed as per the roadway construction plans. The east and northeast areas of the site are to be excavated. Excavation will be from the property line on a 4:1 slope, then outward to Denton Creek on a 1.0% slope. The bank of Denton Creek is to be cut to an elevation of 432. This elevation is based on being one foot above the crest elevation of Carrollton Dam as determined from the Elm Fork flood profiles contained in the RS report. This structure is located a short distance downstream of Sandy Lake Road on the Elm Fork and controls the normal water surface for this section of the Elm 2 f i' 1' Fork and for Denton Creek. With the one foot provided to the low cut elevation, the property will not be encroached into by normal or low flow conditions for Denton Creek. Two small ponds are located in the northeast portion of the ,Sandy Lake Road Property. These ponds are to be left in their existing condition, with excavation to be terminated along the perimeters of the ponds at one foot above the normal pool elevation. The ponds will be protected from sedimentation during construction by placement of silt fences. All disturbed areas will be restored following construction by re-establishment of native grasses. The proposed site grading is shown on the Grading Plan in Appendix J. The section in the existing conditions HEC-2 model is modified to represent the proposed grading as described above. The resulting proposed conditions HEC-2 multi-profile model is provided in Appendix F. The cross section located at sheam station 938+10 is plotted, with existing and proposed configurations superimposed and is contained in Appendix H. The plan view locations of the sections are shown on the Floodplain Work Map which can be found in Appendix I. Floodway models are also derived for existing and proposed floodplain conditions. The floodway limits for the cross section at stream station 938+10 are based on encroachment Method 1, as taken directly from the duplicate floodway model. The entire site is located in the floodway fringe area as defined at this cross section location. The existing and proposed conditions floodway models are provided in the middle and latter portions of Appendix G, respectively. RESULTS r r r r The impacts of the proposed modifications to the Sandy Lake Road Property upon the Elm l~ork floodplains are analyzed in this study. The 100-year water surface elevations vary from 445.21 at the downstream end of the site to 445.29 at the upstream end. Elevations for the 500-year floodplain range from 446.90 to 446.96. These elevations are essentially the same for both the existing and proposed conditions as defined in this study. Greater detail is provided by the Water Surface Elevation Check Table contained within the FEMA Forms of Appendix C. The floodplain delineations are shown on the Floodplain Work Map provided in Appendix I. Based on the existing floodplain conditions defined in this study, 3.7 acres of the site are above the 100-year floodplain, while the entire existing site is inundated by the 500-year flood event. With the proposed grading implemented, 11.4 acres of the Sandy Lake Road Property are removed from the 100-year floodplain and 11.0 acres are above the 500-year floodplain elevation. The changes to the FIRM that result from the proposed project are shown in the latter part of Appendix B. The entire project site is outside of the regulatory floodway based on the floodway limits at stream station 938+10 in the duplicate FIS floodway model. However, based on the plan view projection of the floodway limits from the FIRM, the northeast and northern parts of the property are located within the floodway, as shown on the Floodplain Work Map in Appendix I. The next section in the effective FIS floodway model is located over 3700 feet upstream from the section at 938+10; far beyond the project site limits. Also, the majority of the site that is within the projected floodway limits is to be excavated, which will increase the conveyance available within the floodway.

The project consists of ~H in the floodplain with compensating excavation that results in no increa~ in flood levels and no decrease in flood storage. Hydrologic and Hydraulic Information The two tracts are affected by the flood elevations from the Elm Fork of the Trinity River. However, theso elevations are blocked fxom the actual flow of the river. The area is in an ineffective flow regime and thus has no impact on flood elevations as long as storage levels are not reduced. This means that filling the tracts has no impact on the flood elevations. Storage Determinations It is important to offset any lost storage created by filling the tract. This is accomplished by excavating a portion of the TP&L easement on the 48-acre tract. This area is shown on the drawing in the appendix. In order to determine the storage on the property before and after the proposed pwjoct a computer model was created by describing cross sections through the area. The results of this analysis are included in the appendix. Results The project site is in an area that receives floodwaters from the Elm Fork of the Trinity River, but is isolated from the actual flow of the river. Because of this the area can be filled without impact to the flood elevations of the river. This report has identified storage mitigation so that there is no net decrease in flood storage.

To initiate the Corridor Development Certificate (CDC) permit process, the developer should first contact the local government (City) for a pre-permit conference. The CDC/F!oodplain Administrator of that local government determines whether the project lies within or partially within the Regulatory Zone. If the project lies completely outside the RegulatonJ Zone, the CDC/Floodplain Administrator is not required to take any further action beyond making this determination; no forms are required to be subnfftted and the CDC process ends at this point. ff the project lies within or partially within the Regulatory Zone and there is a possibility that a CDC permit might be granted, the CDC Process must be followed. The Applicant should fill out Parts 1 and 2 of the Standard CDC Form and submit it to the CDC Floodplain Administrator unless the Applicant is seeking an exemption, in which case the Applicant must only complete Part 1. ff the CDC/Floodplaln Administrator decides at any time to deny a CDC permit, tile CDC Process can be terminated.

Hydrololic and Hydraulic Data Design discharges for the 100-year and Standard Project Flood storm events shall be based on urbanization consistent with a "Future Conditions with CDC" Scenario or on supplexnental data provided by the USACE, whichever discharge is larger. (See Table I in Appendix B.) The Applicant should identify these design discharges, including source and date, in the "100 Year Flood Event" and "SPF Flood Event" tables in Part 2 #3. Hydraulic calculations shall be continued for a distance great enough upstream and downstream of the project to verify that water surface elevations are not raised by the proposed hydraulic modifications (spaces are provided in the "100 Year Flood Event" and "SPF Flood Event" tables in Part 2 #3 to list water surface elevations for a number of points upstream and downstream). Elevation data should be computed considering full cross-section widths across the river or creek. Storage data for pre-project and with-project conditions (Part 2 #3) shall be developed within the project borders alone and considering full cross-section widths across the river or creek. Storage change is to be considered "on-site" (i.e., within upstream and downstream limits of the discharge reach.) Compensating valley storage for a proposed activity can also be provided at another site if the USAGE recognizes and approves the "off-site" valley storage. In addition, if any valley storage is lost elsewhere due to the project, storage change shall be addressed on a cross-section width basis, with change based on the original "on-site" storage.
