Speclflcally, this responds to a letter dated June 27, 1994, from Mr. Kenneth M. Griffin~ P.B., City Engineer, City of Coppell, regarding the effective FIS report and Flood Insurance Kate Map (FIRM) for the City of Coppe11, Texas. Mr. Crlffln requested that we revise the effective FIRM to show the effects of ch-nnellzatlon and construction of Parkway Boulevard alon2 Cottonwood Branch and cb-nnellzacion along Denton Creek. All data required to complete our review of this request vere submitted with Mr. Grlffln's June 27 letter, and a letter dated September 8, 1994, and transmlttal dated November 10, 199~, from Ms. Ter{ D. Jones, Dowdey, Anderson and Associates, Inc. Ai~ fees necessary to process this Letter of Map Revision (L0~), a Coral of $1,475, have bean received. ~e have completed our review of the submitted data and the flood data shown on the effective FIRM, and have revised the FIRM to modify the elevations and floodplaln and floodway boundary delineations of a flood having a 1-percent probabillCy of being equaled or exceeded in anJ given year (base flood) along Cottonrood Branch, from Denton Tap Road to approxlmotely 3~200 feet upstream of the Parkway Boulevard Bridge, and alon2 Denton Creek, from Denton Tap Road co approxlma=ely 6,100 feec upstream. As a result of ~hls revlsion~ the Special Flood Hazard Area decreases along Denton Creek end Cottonwood Branch. The base (100-year) flood elevations (BFZs) decrease along Denton Creek and increase sliZhtly alonZ Cottonwood Branch in the viclniCy of Parkray Boulevard. All increases in BFZs are located on che requester's property. The floodways for both creeks chanSe as a resul= of this revision. Public notice of Che revised floodplaln and 'floodway was given in the Citizen's Advocate on September 23, 1994. The modifications are shown on the enclosed annotated copies of FIRM Panel 480170 0010 E and the Floodway Data Table for Cottonwood Branch.

A copy of this notification is enclosed. Any request for reconslderatlon must be based on scientific or technical data. In addition, a notice of chanBes will be published in the Federal Reaister. Because this LONR will not be printed and distributed to primary users, such as local insurance agents and mortgage lenders, your co~unlty will serve as a repository for these new data. We encourage you to disseminate the information reflected by this LOMR throughout the co--aunlty, so that interested persons, such as propert7 owners, local insurance aBents, and mortgage lenders, my benefit.from the information. We also encourage you to prepare a related article for publicanlo~ in your comnunlty's local newspaper. This article should describe the assistance that officials of your community will give to interested persons by provldln~ these data and interpretlnB the NFIP maps. The revisions are effective as of the date of this letter; however, within 90 days of the second publication in the Citizen's Advocate, a citizen may request that the Federal Emergency ~anagement Agency (FENA) reconsider the determination made by this LIDMR. An~ request for reconslderation must be based on scientific or technical data. All interested parties are on notice that, until the 90-day period elapses, the determination to modify the BFEs presented in this LOltl ma~ itself be modified. Due to present funding constraints, FEliA must limit the number of physical map revisions processed. Consequently, we will not republlsh the FIRM and FIS report for your community to reflect the determination of this LOMR at this time.

The Application/Certification Forms required by the Federal Emergency Management Agency (FEMA) are contained within this report. II. HYDRAULIC ANALYSIS The developed area is located between Cottonwood Branch and Denton Creek west of Andrew Brown Community Park. The original Floodplain Reclamation Study on Cottonwood Branch and Denton Creek for this area was prepared by Jerry Parche Consulting Engineers of Arlington, Texas. This report was submitted in October, 1988 and a Conditional Letter of Map Revision (CLOMR) was issued in January, 1989. Since that time there have been numerous changes 'to Denton Creek and therefore impacting the effective model to Cottonwood Branch as well. The current effective models were obtained from FEMA to produce the most accurate information pqssible. A. Floodmlain Ana!vsis of Cottonwood Branch In order to stay within the new requirements of the City of Coppe!! for no increase in water surface elevation, a channel was designed for Cottonwood Branch at the location of the Parkway Boulevard bridge. A layout for the channel and the bridge are found in the this report. Tables i & 2 have been =reared to compare the water surface elevations of the effective model to the revised or post-project conditions model and to the CLOMR. There is no increase in water surface elevation when comparing the post-project model and the effective model. B. F!oodwaVAnalVsis of Cottonwood Branch The workmap contained in the report shows the relationship between the effective floodway boundary and the modified floodway boundary. As the map indicates, the effective floodway boundary has been drawn much closer to the channel on the southside'6f Cottonwood Branch than the northside (sections 34075 & 3~472)= In order to obtain a more objective location of the floodway boundary, encroachment Method 4 was run to determine the floodway boundaries where equal conveyance reduction occurs on each side of the channel. This method was used at sections 34075 and 34472. The resulting encroachment stations for these sections were used to determine the encroachment stations to the Method 1 run used in the Floodway Models shown in Table 1. Referring to table 1, the only increase in floodway elevation occurs at station 8000, which is by .01 feet. However, this remains below the level established by the CLOMR. C. F!oodo!ainAnalvsis of Denton Creek The water surface elevations for Denton Creek are shown in Table ~. The Revised or Post-project conditions model indicate no increase over the effective model and remain well below the levels established by the CLOMR. D. FloodwavAnalvsis of Denton Creek The floodway elevations for Denton Creek are shown in Table 2. The Revised or post-project conditions model indicate no increase over the effective model and remain below the levels established by the CLOMR with the exception of section 36970. E. Parkway Boulevard Bridae A layout of the Parkway Boulevard bridge and vertical profile are included in this report. The beam low chord has been established at 465.7 feet. The 100 year water surface elevation is at 463.37 leaving a freeboard of 2.33 feet. The 500 year water surface elevation is at 463.96, well below the beam low chord elevation. F.

Box 478 Coppelll, Texas 75019 N26 SS Case No.: 89-06-06R Dear Mayor Dugget: This is in reference to a let=or dated October 10, 1988, and a floodplain study submitted by Mr. Russell R. Doy!e, P.E., City Engineer for ~e City of Coppoll. In his letter, which was forwarded to us by our Region VI office, Mr. Doyle requested a conditional Letter of Map Revision (LCaMR) for a proposed fill [roject along Cottonwood Branch and Denton Creek on behalf of Jerry Parche Consulting Engineers. The submitted floodplain study entitled Flood- plain Reclamation Study on Cottonwood Branch and Denton Creek, dared Ottoher 1988, prepared by Jerry Parche Consulting Engineers, included ~he following: a description of the methodologies used; PFEC-2 models of Denton Creek and Cottonwood Branch representing existing and proposed conditions; and delineations of =he existing and proposed 100-year floodplain boundaries and the proposed regularcry floodway boundaries on a topographic map. Prior to =he commencement of cur review, we received the initial fee of $350.00 for processing a conditional LCMR request of this type. This fee was sufficient to cover the review and processing costs associated with =his submittal. As explained in the submi:ted floodplain study, additional cross sections were inserted into the REC-2 models for Denton Creek and Cottonwood Branch (in =he vicinity of Denton Tap Road), w~ich are 'not reflected in =he preliminary Flood Insurance Study (FIB) for the City Of C~ppell, dated September 22, 1988. These models are therefore the best available models and will he used as the new baseline models in order to evaluate the effects of ~he proposed project. It is impor=ant to note, however, =hat these submitted models incorporated a s~-ale construction and floodplaln fill project known as t_he Magnolia project. We have recently received a request for a map revision from your community regarding the Magnolia project and are currently awaiting the submission of a written maintenance agreement for =his project as specified under Part 65.6 (a) (12) of =he National Flood Insurance Program (NFIP) regulations. Therefore, the prolimit=dry FIB will not be revised to reflect the updated existing conditions until the aforementioned maintenance agreement is received. After reviewing the submitted data, we have determined =hat the p~posed fill project meets ~he minimum floodplain management criteria of t_he NFIP. If the project is completed as proposed, the 100-year wBter-surface elevations of Denton Creek would remain unchanged except at cross section 34850 where an increase of 0.1 foot would occur. In a~dition, the 200-year floodplain and regularcry floodway of Denton Creek would be decreased as indicated in the submitted floodplain study. Also, if the project is.completed as proposed, =he 100-year ~-~ter-surface elevations of Cottonwood Branch w~uld increase (a maximum of 0.9 foot) and the 100-year floodplain and regularcry floodway woul~ be modified as depicted in the submitted floodplain study. It is important t~ note ~hat the increase in the 100-year w~ter-surface elevations of Denton -- 8 " Creek and Co=to=wood Branch are due to the placeme~= of fill cutslde of the regularcry flocdway of each s=ream. Please no=e that future revisLuns to ~he Flood Insurance Rate Map ([IRM) and Flood Boundary and Floodway Map (FBFM) or restudies of t. he flood hazards in =his area could modify =his de=ermine=ion. This determine=ion is based on =he 100-year flood discharges ccmpu=ed in the preliminary FIS for your community, and does not consider sul~sequen= changes in watershed charac=eristics tha~ would tend to increase flood discharges. The development of =his ~roject and ouher projects upstrea~ could result in increased flood discharges, which, in turn, could result in increased 100-year flood eleva=ions. Future restudies of your communlty's flood hazards woul~ =aXe into accoun= the cumula=ive effects of development on flood discharges, and could =herefore establish higher 100-year flood elevations in =his area. This conditional L0~R is based on minimum flo0dplain managemen= criteria established under the NFIP. Your community is responsible for ap.orovlng all proposed floodplain developmen=s, including =he project upon which request is based, and for assuring that necessary permits required by Federal or State law have been received. State a~d community officials, based knowledge of local conditions and in the interest of safety, may so: higher s=andards for construction or may limit develop=on= in floodplain areas. If =he State of Texas or the Ci=y of Coppoll has adopued more restrio=ire comprehensive floodplain managemen= criteria, =hose criteria ~ke precedence over =he minimum NFI~ requirements. Please ncUe =he requiremen=s for floodway revisions as outlined in NFIP regulation Part 65.7 (b) (1) (copy enclosed), which s~ates that when s floodway change is proposed, a copy of a public notice distributed by ~he communi=y s~a=ing ~e commu~=y's in~en= =o revise ~e flo~way, or a s=a=emen= by ~e co~i=y ~a= i= has nouified all affec=ea properUy o~ers and affec=e~ adjacenU juri~lc=ions musU be s~=~ed =o ~e ~deral ~ergency ~nagemen~ Agency (F~A).

The summary must include a desc~ption of any changes made from model to model (e.g., Duplicate Effective model to Corrected Effe~'ve model). At a minimum, the Duplicate Effective (item 1) and the Revised or Post-Project Conditions (item 4) models must be submitted. Sea instructions for directions on when other mndds may be required. for areas which do not have detailed rioodin: Only the 100-year (Base) flood profile is required. A hydraulic model is not required for areas which do nut have detailed flooding; however, BFEs may not ha added to the revised FIRM. if a hydraulic model is developed for the area, items 3 end 4 described below must be submitted. If hydraulic models are not deneloped, hydraulic analyses (Including all catcutatlons) for existing or prepreject conditions and revised Or post-proJeot conditions must ha submitted. .. 1. Duplicate Effective Model ii Natural File Name b<3 Ftoodw/y Rle Name CBENC Copies of the hydraulic analysis used in the effective FIS, referred to as the effective models (10-, 50-, 100-, and 500-year multi- profile runs and the floodway run) must he obtained and then reproduced on the requeste's equipment to produce the Duplicate Effective model. This is required to assure that the effective models input data has been transfeTed conectly to the requester's .- equipment end to assure that the revised data will be integrated into the effective data to provide a Continuous FIS model upstream and downstream of the revised reach. 2. Corrected Effeottve Model [] Natural File Name [] Floodway File Name The Corrected Effective model is the model fiat corrects any errors that occur in the Duplicate Effective madel, adds any addiUonal cross sections to the Ou_plicate Effective model, or inCorporatas more datailad topographic infonnatlon than that used in the currently effective model. The Correctly Effective model must not reflect any man-made physical changes sinca the date of the effective model.
