K3UERQUE, N.M. 87125 COPPELL, AUGUST, 1989 DALLAS COUNTY, TEXAS Prepared By: dpJerry Parcl~ Consulting Engineers 320 Vv'estway Place · Suite SOl · Arlington, Texas 76018 * Metro 18171 467-2418 · (817)465-0259 Jerry Parch Consulting Engineers September 2, 1989 Mr. David Lushbaugh Management Engineering and Technical Services Division Dewberry & Davis 8401 Arlington Boulevard Fairfax, Virginia 22031 RE: JP No. 88009; Flood Plain Reclamation; Denton Creek and Cottonwood Branch; Coppell, Texas Dear David: On February 21, 1989 we submitted a study to the City of Coppell entitled Flood Plain Reclamation Study on Cottonwood Branch and Denton Creek for Flood Plain Reclamation and Construction of Parkway Boulevard Bridqe. This study was prepared for submittal to FEMA in support of our request for a Conditional Letter of Map Revision for the Parks of Coppell project. The proposed project is located in the City of Coppell, Dallas County, Texas, on the west side of Denton Tap Road. Our previous submittal contained the following: ae Four HEC II hydraulic models of the 100-year flood in Denton Creek and Cottonwood Branch as follows: Model DCEX - Existing Conditions on Denton Creek from Section 32150 to Section 39440. Model COEX - Existing Conditions on Cottonwood Branch from Denton Creek Section 32150 to Cottonwood Branch Section 8000. Model DCPR - Conditions on Denton Creek with proposed fill in the Parks of Coppell project. The reach analyzed in this model extended from Denton Creek Section 32150 to Section 39440. Model CPR4 - Conditions on Cottonwood Branch with proposed fill in the Parks of Coppell and a proposed Parkway Boulevard bridge over Cottonwood Branch. The reach analyzed in this model extended from Denton Creek Section 32150 to Cottonwood Branch Section 8000. B. Exhibit "A" showing Existing Conditions Prior to Construction. C. Exhibit "B" showing Conditions with Proposed Reclamation and Bridge. 320 Westway Place, Suite 501 · Arlington, Texas 76018 · Metro (817) 467-2418 · (817) 465-0259 Mr. David Lushbaugh JP No. 88009 September 2, 1989 Page 2 of 5 Cross sections of Denton Creek and Cottonwood Branch as included in the hydraulic models presented in the February, 1989 report. These were submitted separate from the bound report. The information presented herein provides an update of the aforementioned February, 1989 submittal in response to a letter received from Mr. John L. Matticks, Chief, Risk Studies Division, Federal Insurance Administration, Dated July 3, 1989. A copy of Mr. Matticks letter is enclosed. In his letter, Mr. Matticks cites differences in the technical report we presented in February, 1989, and a report submitted by Kimley-Horn and Associates, Inc. in January, 1989 on behalf of the City of Coppell to revise the City's Flood Plain maps. Mr. Matticks letter states that these differences should be resolved so that a single HEC II model of existing conditions in Denton Creek and Cottonwood Branch results. In response to this request, the city's flood plain consultant, Mr. Ron Morrison of Kimley-Horn and Associates, and I have met on several occasions and have resolved all differences between our respective existing condition models in the project area. A letter regarding this is being provided to FEMA by the City. The City of Coppell F.I.S. containing these revised models of Denton Creek and Cottonwood Branch will be submitted to FEMA in early September, 1989. Ail hydraulic models presented in our February, 1989 submittal have been rerun and are included herein. The downstream limit of these hydraulic models is Section 24700 on Denton Creek. Hydraulic models of the 100-year flood with existing conditions in Denton Creek and Cottonwood Branch are included herein in Appendix A. Hydraulic models of proposed reclamation and the proposed Parkway Boulevard bridge over Cottonwood Branch are included herein in Appendix B. These hydraulic models are identified below. Model DCEXKH - Existing Conditions in Denton Creek from Section 24700 to Section 39440. Model CEX3KH - Existing Conditions in Cottonwood Branch from Denton Creek Section 24700 to Cottonwood Branch Section 8000 in the Villages of Cottonwood Creek project which is upstream of the Parks of Coppell. Mr. David Lushbaugh JP No. 88009 September 2, 1989 Page 3 of 5 Model DCPRKH - Proposed Conditions in Denton Creek. From section 24700 to section 32230 on the upstream side of Denton Tap Road this model is similar to model DCEXKH since this reach is outside of the project area and no reclamation is proposed. Sections 32250, 32305 and 32725 are in the combined Denton Creek-Cottonwood Branch flood plain area and contain proposed reclamation on the south side of Cottonwood Branch authorized by a Conditional Letter of Map Revision received from FEMA dated January 26, 1989 (Case No. 89-06-06R). Sections 33145 through 34950 include proposed reclamation on the south side of Denton Creek in the Parks of Coppell, if any. Sections 36970 through 39440 are upstream of the project and are similar to existing conditions model DCEXKH. Model CPR4KH - Proposed Conditions in Cottonwood Branch. From sections 24700 to section 32725 this model is similar to model DCPRKH as described above since this reach is in the Denton Creek flood plain or combined Denton Creek- Cottonwood Branch flood plain area. Sections 32816 through 33116 model the proposed Parkway Boulevard bridge and channel improvements. Sections 33560 through 34472 model proposed reclamation in the Parks of Coppell. Sections 6710 and 8000 are existing cross sections located upstream in the Villages of Cottonwood Creek project. In his letter of July 3, 1989, Mr. Matticks cites two specific differences between the models we submitted to the City in February, 1989 and the models submitted to FEMA by Kimley-Horn on behalf of the City of Coppell in January, 1989. These differences and the resolutions arrived at by Kimley-Horn and our firm are described below. Differences in the location of the upstream limits of the common Denton Creek-Cottonwood Branch Flood Plain. After reviewing the detailed topography available for the Parks of Coppell project and comparing bank elevations on the south side of Denton Creek with 100- year flood levels, our firm and Kimley-Horn have agreed that the upstream limits of the common flood plain are approximately at Denton Creek section 32725. Both the revised city models to be submitted to FEMA and revised Mr. David Lushbaugh JP No. 88009 September 2, 1989 Page 4 of 5 models contained herein for the Parks of Coppell project evidence this by a change in discharge from the combined flood plain discharge at section 32725 to the 100-year flood discharge in each creek at the next section upstream. Differences is the 100-year Flood Discharges used in the City's models and the Parks of Coppell models. Discharges used in the City of Coppell study prepared by Kimle¥-Horn & Associates that will be submitted to FEMA and our models of Denton Creek and Cottonwood Branch prepared for the Parks of Coppell project as revised and presented herein are now similar. Current hydraulic models use the following 100-year flood discharges at the sections listed in Mr. Matticks letter. CROSS SECTION 100-YEAR FLOOD DISCHARGE (c.f.s.)

The study description included with our initial submittal to the City of Coppell in February, 1989 is included in Appendix C of this report. Much of the information regarding the Parks of Coppell project and the Denton Creek and Cottonwood Branch flood plains presented in that report is still current. Flood plain and floodway elevations and flood discharges presented in our February, 1989 report, however, are superceded by information presented in this letter and in Appendices A and B contained herein. Mr. David LushbauGh JP No. 88009 September 2, 1989 PaGe 5 of 5 Exhibits "A" and "B" showing existing and proposed flood plain conditions respectively in the Parks of Coppell are included in the map pocket in the back of this report. Cross sections of Denton Creek and Cottonwood Branch modelled for this study, as revised herein, are presented separate with this report. I trust that the information presented herein will permit Dewberry & Davis to proceed with the review and issuance of a Conditional Letter of Map Revision for this project. The City of Coppell has informed me that they will provide a letter to FEMA endorsing the proposed reclamation and Parkway Boulevard bridge concurrent with this submittal to you. If you need any other information or have any questions, please call. Since time is now extremely important, I appreciate your prompt attention to this matter. Sincerel~ erry ~a~he' ,P.E.

Doyle, P.E., City Engineer and Floodplain Administrator for the City of Coppell, in which he requested, on your behalf, that the Federal Emergency Management Agency'(FEMA) Jssuo a conditional Letter of Map Revision (LO,MR) for the proposed Parkway Boulevard bridge located near the confluence of Cottonwood Branch and Denton Creek. With his letter, which was forwarded to us by our Region VI office, Mr. Doyle submitted a technical report prepared by your firm, entitled Floodplain Reclamation Study on Cottonwood Branch and Denton Greek for Floodplain Reclamation and Construction of Parkway Boulevard Bridge, dated February 1989. This report contained the following: HEC-2 hydraulic models representing existing and proposed lO0-year flood and floodway condi- tions for Denton Creek and Cottonwood Branch; topographic mapping delineating the proposed lO0-year floodplain boundary and the proposed floodway configura- tion; and plotted cross sections for Denton Creek and Cottonwood Branch. Please note that we have also received a January 12, 1989 letter from Mr. Doyle, in which he requested that FEMA revise the September 22, 1988 Flood Insurance Study and Flood Insurance Rate Map for the City of Coppell to include updated corporate limits information and the results of a technical report prepared by Kimley-Horn and Associates, Inc., consulting engineers for the City of Coppell. A comparison of the hydraulic models for Cottonwood Branch and Denton Creek from your submittal and those from the Kimley-Horn and Associates, Inc., submittal indicates differences in the technical analyses that yield different results. These differences are listed below. Ktmley-Horn and Associates, Inc., has modeled the two streams with an assumed common floodplain from their confluence upstream to a point approximately 1,220 feet upstream of Denton Tap Road. Your submittal models the two streams as having an assumed common floodplain from their confluence upstream to a point approximately 475 feet upstream of Denton Tap Road. The 100-year flood discharges utilized in the submitted HEC-2 hydraulic models for Denton Creek are outlined below.

INTRODUCTION On October 6, 1988 a report entitled Flood Plain Reclamation Study on Cottonwood Branch and Denton Creek prepared by our firm was submitted to the City of Coppell. This report contained hydraulic models of Denton Creek and Cottonwood Branch for submittal to the Federal Emergency Management Agency (FEMA) to request a Conditional Letter of Map Revision for a project on the south side of Cottonwood Branch west of Denton Tap Road. The limited amount of flood plain reclamation addressed in that report is intended to allow for the immediate construction of access roadways to the new Coppell High School within the Parks of Coppell project. In response to that request a Conditional Letter of Map Revision from FEMA was received on January 27, 1989. The reclamation project authorized thereby is currently under construction. This report will address proposed reclamation of flood plain property within the Parks of Coppell west of Denton Tap Road not included in the October, 1988 study. This includes flood plain areas on the north and south sides of Cottonwood Branch generally west of the Coppell City Park upstream through the Parks of Coppell to the eastern limits of the adjacent development - the Villages of Cottonwood Creek. Hydraulic models prepared for this study also include a proposed bridge for Parkway Boulevard over Cottonwood Branch and proposed reclamation of flood plain areas on the south side of Denton Creek within the Parks of Coppell. II. PURPOSE AND SCOPE This report presents hydraulic models for reclamation of flood plain property within the Parks of Coppell development upstream (west) of Denton Tap Road. The purpose of this. study is to provide technical information to FEMA to request a Conditional Letter of Map Revision. As shown in our previous report dated October, 1988, although Denton Creek and Cottonwood Branch confluence downstream or east of Denton Tap Road, the 100-year flood plains of these streams confluence upstream of this roadway. Report Initially Submitted February 21, 1989 The October, 1988 study presented detailed hydraulic models of the existing 100-year flood plains of Denton Creek and Cottonwood Branch from Denton Tap Road upstream to adjacent areas west of the Parks of Coppell. These Models of existing flood plain conditions in Denton Creek and Cottonwood Branch prepared for the October, 1988 study were reviewed for use in this study. Primary features of the Plan of Reclamation studied in the proposed condition hydraulic models presented herein are described below: ae Reclamation of the Denton Creek flood plain south of the existing channel. This reclamation is proposed to either the 100-year floodway limits or the Parks of Coppell north property line, whichever is further from the creek. Grading for the extension of Parkway Boulevard west from the westerly limits proposed for this roadway in the October, 1988 study upstream to the west property line of the Parks of Coppell. This construction will include a bridge over Cottonwood Branch located at the downstream limits of the Cottonwood Branch flood plain. Reclamation of the Cottonwood Branch flood plain upstream of the proposed Parkway Boulevard bridge to the west property line of the Parks of Coppell. This reclamation is proposed to the floodway limits on both sides of Cottonwood Branch with the exception of a small wetland area on the north side of the creek near the west property line. This wetland area lies partially within the floodway and partially outside of the floodway. The proposed plan will permit the entire wetland area to remain in its natural state. Hydraulic models were prepared to analyze the proposed reclamation and bridge on Cottonwood Branch and proposed reclamation of the Denton Creek flood plain. The results of these models were then compared to models of the existing streams prepared for this report as well as the current F.I.S. models and models previously prepared for existin~ adjacent developments. III. LOCATION AND DESCRIPTION The project site is shown on Figure 1 and flood plain features and location of surrounding developments are shown on Exhibit A, located in the map pocket in the back of this report. The flood plains of Denton Creek and Cottonwood Branch join together within the portion of the Parks of Coppell development that is west of Denton Tap Road. -2- Report Initially Submitted February 21, 1989 STUDY SITE ~AP(y~rt& FIGURE 1 LOCATI ON MAP PARKS OF COPPELL Referring to Exhibit A, the site is bounded on the west by the Villages of Cottonwood Creek project and on the north by the Magnolia Park project, also known as the Century Park Addition and formerly known as Lincoln/Coppell. Andrew Brown Community Park, a city park, lies between the Parks of Coppell and Denton Tap Road and also lies between Denton Creek and Cottonwood Branch. The entire park site lies within the 100-year flood plain. Downstream or east of Denton Tap Road, the Vista Ridge project is located north of Denton Creek and additional City Park property and additional area in the Parks of Coppell are located south of Denton Creek. Grading and flood plain reclamation in surrounding projects is complete. Denton Tap Road borders the easterly limits of the Parks of Coppell and is the major north-south thoroughfare through the city. This roadway is currently being improved to a six-lane divided thoroughfare from Cottonwood Branch south to Bethel Road. Parkway Boulevard is one of the major east- west roadways in the city. The Coppell Municipal Building is located on the south side of Parkway Boulevard just east of Denton Tap Road. Upon completion through the Parks of Coppell, Parkway Boulevard will link Coppell Road on the west side of the city and MacArthur Boulevard on the east side of Coppell. IV. EXISTING 100-YEAR FLOOD PLAIN The 100-year flood plains of Denton Creek and Cottonwood Branch have been significantly modified in the last few years by projects in the vicinity of Denton Tap Road. These projects and their general locations are as follows: PARKS OF COPPELL: Flood Plain Reclamation on the south side of Denton Creek and Cottonwood Branch east of Denton Tap Road. VISTA RIDGE: Flood Plain Reclamation, levees, and channel improvements on the north side of Denton Creek east of Denton Tap Road. MAGNOLIA PARK: Flood plain Reclamation with some floodway excavation on the north side of Denton Creek west of Denton Tap Road. VILLAGES OF COTTONWOOD CREEK: Flood plain Reclamation on the north side of Cottonwood Branch and the south side of Denton Creek west of the Parks of Coppell. -4- Report Initially Submitted February 21, 1989 As reported in our October, 1988 study, hydraulic models were obtained for each of these projects to establish existing flood plain conditions in the Parks of Coppell west of Denton Tap Road. All hydraulic models are based on the computer program - Water Surface Profiles, HEC II. A hydraulic model of the 100-year flood plain and floodway in Denton Creek from Denton Tap Road upstream to cross section 39440, entitled DEEXPK was prepared in the October, 1988 study. A model of the 100-year flood plain in Cottonwood Branch was also prepared entitled COEXPK, which included the reach from Denton Tap Road upstream to cross section 8000 in the Villages of Cottonwood Creek. Models DEEXPK and COEXPK were reviewed for this report. Minor changes were prepared as described below. The existing flood plain and floodway in the project area are shown on Exhibit A located in the map pocket in the back of this report. A. Existing Conditions - Denton Creek A computer model entitled DCEX was prepared in this study to define existing flood plain conditions in Denton Creek from the downstream side of Denton Tap Road upstream to cross section 39440. This section is upstream of the Parks of Coppell. This model is presented in Appendix A and is similar to model DEEXPK presented in our October, 1988 study with the following changes. Some of the flow areas in the southern portions of cross sections 33470 and 34260 in the right overbank were deleted to better model expanding flow in Denton Creek as it spreads in a south- easterly direction to confluence with flooding in Cottonwood Branch. Since right channel bank stations are used as effective flow limits up to the elevations of these bank stations, and since these elevations are not exceeded by the 100-year flood, this revision only affects water surface elevations at discharges in excess of the 100-year frequency event. In the previously prepared model DEEXPK, 100-year floodway limits on the right side of the flood plain used at sections 34260 and 34850 are outside of the 100-year flood limits. Therefore no encroachment occurs in the floodway model at these cross sections. The floodway limits on the right side of these cross sections were adjusted in model DCEX to be at approximately the limits of the 100-year flood plain. The amount of encroachment remains insignificant, however the 100-year flood plain and floodway limits at these cross sections are now similar. -5- Report Initially Submitted February 21, 1989 Areas within Cottonwood Branch in the southern portion of Denton Creek section 35170 are deleted due to high ground between the two creeks preventing Denton Creek flooding from entering Cottonwood Branch at this cross section. The revisions in the flood plain model of existing conditions in Denton Creek provide more accurate results during extremely rare flood events - events having a frequency in excess of the 100-year flood. However, due to the use of effective flow limits at the right channel bank station of Denton Creek in cross sections prepared in model DEEXPK and more current model DCEX presented herein, and since the 100-year flood levels do not exceed the elevation of these bank stations, 100-year flood plain and floodway results obtained in both model DEEXPK previously prepared and model DCEX prepared in this study are similar. Existinq Conditions - Cottonwood Branch A model of existing 100-year flood conditions in Cottonwood Branch through the Parks of Coppell from Denton Tap Road upstream to section 8000 in the Villages of Cottonwood Creek was prepared for this study. This model is entitled CEX3 and is presented in Appendix A in this report. Model CEX3 is similar to the existing condition flood plain model of Cottonwood Branch prepared in our October, 1988 study (COEXPK) except at cross section 35170. This section was incorporated into model COEXPK exactly as prepared in the current Flood Insurance Study. Although indicative of the flood plain topography near the west property line of the Parks of Coppell, elevations used in cross section 35170 as taken from the existing FEMA model, (section 5275 in the Villages of Cottonwood Creek model) do not coincide with existing ground elevations from detailed topography available in the area. Therefore it was decided to delete cross section 35170 from the model and to prepare cross section 34472 of the Cottonwood Branch flood plain. Section 34472 was prepared from detailed topography obtained from field surveys in the same vicinity of the flood plain as Section 35170. The table below gives a comparison of 100-year flood elevations and floodway elevations obtained in models CEX3 and COEXPK upstream of cross section 34472 for existing conditions in Cottonwood Branch. Report Initially Submitted February 21, 1989 TABLE 1: Comparison of 100-year flood elevations. Existinq Conditions in Cottonwood Branch.

As shown in the table, the 100-year flood elevation at cross section 6710 obtained in this study using section 34472 downstream is lower by approximately 0.51 feet from the elevation obtained in the October, 1988 model which used the existing F.I.S. cross section 35170 downstream of section 6710. The floodway elevation is lower by approximately 0.47 feet at section 6710. Elevations at the next cross section upstream, section 8000, obtained in this study are similar to elevations obtained in previous studies for existing channel conditions and floodway. V. PROPOSED RECLAMATION PLAN Features of the proposed plan of reclamation are shown on Exhibit B located in the map pocket in the back of this report. The reclamation area on the south side of Cottonwood Branch west of Denton Tap Road, which was the subject of our October, 1988 study, is shown on this exhibit as well as the flood plain reclamation currently proposed west of the High School Access Road and the City Park. Computer models were prepared to study impacts of the proposed reclamation on the 100-year flood plains of Denton Creek and Cottonwood Branch. The model of the Cottonwood Branch flood plain was also used to prepare a hydraulic design of the Parkway Boulevard bridge. The 100-year flood plain and floodway conditions with proposed reclamation and bridge improvements were determined using the computer program - Water Surface Profiles - HEC II. -7- Report Initially Submitted February 21, 1989 Following is a description of the computer models of proposed flood plain conditions prepared for this study. These models are presented in Appendix B of this report. Model CPR4 - This computer model determines 100-year flood plain and floodway conditions in the Cottonwood Branch flood plain with all proposed reclamation in the Parks of Coppell between Denton Tap Road and the west property line of this project. The model is extended upstream into the Villages of Cottonwood Creek project to tie into existing flood profiles upstream. The proposed Parkway Boulevard bridge is included in this model between cross sections 32816 and 33016. Model DCPR - This computer model determines 100-year flood plain and floodway conditions in the Denton Creek flood plain upstream of Denton Tap Road. Constructed improvements in the Magnolia Park project are included in this model as well as proposed reclamation in the Parks of Coppell. One hundred year flood discharges used in the proposed condition models are similar to discharges used in the existing condition models. Cross sections 32150 through 32725 are similar in both flood plain models and are used to analyze the area where the flood plains are common under 100-year flood conditions. This area is considered to be in the Denton Creek flood plain since Denton Creek is the dominant stream and Cottonwood Branch is a tributary. One hundred year flood discharges used in the studied reaches are given in Table 2. TABLE 2: 100-year Flood Discharges Stream Reach Discharge CFS Denton Creek 32150-32725 21,300 Denton Creek 33145-36970 14,900 Denton Creek 39440 15,600 Cottonwood Branch 32816-8000 7,300 -8- Report Initially Submitted February 21, 1989 A. Proposed Reclamation - Denton Creek Proposed reclamation in the Denton Creek flood plain from section 32250 to section 32725 presented in Model DEPRPK in our October, 1988 study is repeated in Model DCPR presented herein in Appendix B. This reclamation consists of filling in. the south side of the common Denton Creek - Cottonwood Branch flood plain outside of the floodway. Water surface profiles determined in both models of the 100-year flood plain and floodway in this reach are similar. Upstream of section 32725 Denton Creek and Cottonwood Branch flood plains are distinct. Filling is proposed to the Parks of Coppell property limits at sections 33145, 33470 and 34260 in the south overbank areas of -the Denton Creek flood plain. The property line is south of the floodway limits at these cross sections. The existing elevation of the south bank of Denton Creek is above the 100-year flood elevation at cross sections 34850, 34950 and 35170 where the south bank of the creek lies within the Parks of Coppell property. Therefore no flood plain encroachments are planned at these cross sections since the natural channel bank is above 100-year levels. Proposed reclamation of the Denton Creek flood plain upstream of section 32725 results in no changes in water surface elevation or velocities during the 100- year flood. This is due to the fact that effective flow areas in Denton Creek upstream of section 32725 within or adjacent to the Parks of Coppell are unchanged by the proposed filling. Table 3 below presents a comparison of water surface elevations from Profile One of existing condition model DCEX, which represents existing conditions in the flood plain, and Profile One of proposed condition model DCPR, which represents conditions in Denton Creek with the proposed project. As seen in the Table, differences in water surface elevation are extremely small. -9- Report Initially Submitted February 21, 1989 TABLE 3: Existing and Proposed Water Surface Elevations Denton Creek - 100-year Flood Cross Existing Conditions Proposed Conditions Section Model DCEX Model DCPR 32150 458.81 458.81 32200 459.28 459.28 32230 459.29 459.29 32250 459.29 459.26 32305 458.57 458.58 32725 461.89 461.91 33145 462.16 462.19 33470 462.41 462.44 34260 463.17 463.20 34850 463.23 463.25 34950 464.26 464.28 35170 464.52 464.54 36970 465.48 465.49 39440 467.82 467.82 -10- Report Initially Submitted February 21, 1989 B. Proposed Reclamation - Cottonwood Branch The computer model CPR4 was prepared to study the 100- year flood and floodway in Cottonwood Branch with proposed conditions in the channel and flood plain. This model is presented in Appendix B. Model CPR4 is similar to existing condition model CEX3 presented in Appendix A between cross sections 32150 and 32725 with the exception of the proposed filling in the Parks of Coppell in the right overbank areas. Within this reach, model CPR4 is similar to model COPRPK prepared for our October, 1988 study and model DCPR of the Denton Creek flood plain presented in this report. Upstream of section 32725, proposed conditions in Cottonwood Branch analyzed in model CPR4 can be divided into three stream reaches. Channel and bridge improvements between sections 32816 and 33116. 2. Proposed fill to the floodway limits from section 33560 to 34472. Existing cross sections upstream in the VillaGes of Cottonwood Creek from section 6710 to 8000. As shown on Exhibit B, cross sections 32816 through 33116 were prepared to analyze the proposed Cottonwood Branch channel through the Parkway Boulevard bridge. The proposed bridge crosses the creek at a skew to the flow, however bridge bents and abutments will be aligned parallel to the flow. The proposed bridge consists of three spans. Each span has a width of 42.4 feet between center of piers or between center of piers and adjacent abutments, perpendicular to the flow. Therefore, total bridge length is 127.2 feet measured perpendicular to the flow in the creek. Proposed bridge sections are presented on Sheet 6 of the cross section drawings submitted with this report. The low chord or low beam elevation of the bridge is elevation 464.5 which is a minimum of two feet above the 100-year flood elevation. Where appropriate, flow expansion is modelled by limiting the extent of cross sections input to the model. Channel sideslopes downstream, through and upstream of the bridge will be protected. -11- Report Initially Submitted February 21, 1989 Channel improvements at the Parkway Boulevard bridge will transition to the natural channel upstream of cross section 33116. Upstream of this channel transition to the west property line of the Parks of Coppell, the existing Cottonwood Branch channel will remain in a natural state. The flood plain in this area will be reclaimed generally to the floodway limits by filling to elevations above the 100-year flood levels. No filling is proposed in a wetland area on the north side of the flood plain near the west property line of the Parks of CoDpell as shown on Exhibit B.

The bridge and channel improvements at Parkway Boulevard lower flood levels substantially from existing 100-year flood elevations. By comparison of results in Profile 1 of Model CEX3 and Profile 1 of Model CPR4, it is apparent that velocities in the Cottonwood Branch channel at cross sections upstream of section 33116 are very similar to velocities under existing channel conditions. SUMMARY The study presented in this report is an extension of the study prepared by our firm that was presented to the City of Coppell in October, 1988. This previous study included limited flood plain reclamation on the south side of the common Denton Creek/Cottonwood Branch flood plain upstream of Denton Tap Road. This study has been prepared to present analysis for flood plain reclamation of the entire Parks of Coppell project upstream of Denton Tap Road. Reclamation addressed in the October, 1988 study has been included in this report. The portion of the Denton Creek flood plain outside of the floodway and within the Parks of Coppell project will be reclaimed by filling to levels above the 100-year flood elevation. Results of hydraulic studies presented herein demonstrate that the proposed filling in the Parks of Coppell has essentially no impact on flood elevations in Denton Creek due to the existing high bank on the south side of the creek rendering existing inundated areas within the Parks of Coppell as non- effective flow areas. Areas in the Parks of Coppell within the Cottonwood Branch flood plain outside of the 100-year floodway are proposed to be reclaimed from the flood plain by filling above 100-year flood levels. Hydraulic models prepared for this study were also used to develop a hydraulic design for the Parkway Boulevard bridge over Cottonwood Branch. Results obtained in these models show that the flood plain response due to proposed reclamation of the Cottonwood Branch flood plain and construction of the Parkway Boulevard bridge is in compliance with regulations of the Federal Emergency Management Agency and the City of Coppell. In order that the proposed construction of Parkway Boulevard and flood plain reclamation can proceed, we request on behalf of our client, ABQ Development Corporation, that the City of Coppell. review the information presented herein and forward this information to FEMA with an endorsement of our request for a Conditional Letter of Map Revision for this project. -14- Report Initially Submitted February 21, 1989 This report has been prepared for the exclusive use of ABQ Development Corporation and its designated consultants.
