Griffin, P.E. Assistant City Manager/ Director of Public Works City of Coppell 255 Parkway Blvd. Coppell, Texas 75019 Fax: 214- 393 -0931 or 214- 304 -3570 °IIz111� �t� LcI+ Re: Second Review of a Conditional Letter of Map Revision Application prepared by MHE, for a Portion of Denton Creek Upstream of DeForest Road, City of Coppell, Texas - Windsor 'Estates site. Dear Mr. Griffin: We have reviewed hydraulic models for the downstream reach of Denton Creek prepared by Morrison Hydrology Engineering Inc. (MHE) in August 1998. These models are revisions to earlier models that were submitted for our review in March 1998, as part of a Conditional Letter of Map Revision ( CLOMR) application package (Conditional Letter of Map Revision Application for a Portion of Denton Creek Upstream of DeForest Road in the City of Coppell, Texas) to the Federal Emergency Management Agency (FEMA). We did not review the entire CLOMR report package at this point. Mr. Morrison stated in a letter accompanying the models "...We have only provided,/loodway models. If this analysis is okay we will complete the report". The models that we were sent only run discharges based on (FIS) existing condition landuse hydraulics. In addition to this letter report, you will find included in this package one (1) 11 "x17" sketch prepared for this project by Halff Associates, Inc. which shows the existing floodplain, the US Corps of Engineers (COE) cross - section locations for the Elm Fork of the Trinity River, and other cross - sections locations suggested by Halff Associates, Inc. to correctly model the Elm Fork - Denton Creek confluence. 1. Effective flows for Denton Creek are not modeled properly in the added cross - sections. The cross - sections that were added by MHE in the existing condition model downstream of the proposed reclamation site overestimate Denton Creek conveyance in. the left overbank. The left overbank in cross - sections 15850 through 17735 is about 7400 R wide (it reaches as far as I -35 -E at some cross - sections). Flows from Denton Creek are not effective across the whole width of the Elm Fork floodplain. 2. The existing stream hydraulics models (which date back at least to the original Dallas County FIS work in 1977) do not accurately depict the confluence of Denton Creek with the Elm Fork of the Trinity River. Apparently, the USACE, FWD, did not correct this deficiency in the course of developing new river hydraulic models for the Upper Trinity River Feasibility Study. A careful and DALLAS • FORT WORTH • HOUSTON • MCALLEN TRANSPORTATION • WATER RESOURCES • LAND DEVELOPMENT • MUNICIPAL • ENVIRONMENTAL • STRUCTURAL MECHANICAL • ELECTRICAL • SURVEYING • GEOGRAPHIC INFORMATION SYSTEMS ARCHITECTURE LANDSCAPE ARCHITECTURE • PLANNING II Halff Associates NEI ENGINEERS • ARCHITECTS • SCIENTISTS PLANNERS• SURVEYORS accurate representation of the hydraulics involved is crucial to this project and to existing and future developments in this area. We have attempted to show cross - section locations on the attached exhibit that we feel are more representative of lower Denton Creek. Those cross - sections are 1800 -2800 feet in length and tie to high ground in the left overbank of Denton Creek (around the Dallas Gun Club property). The cross - sections locations must correctly represent the existing constriction just south of the proposed reclamation project. The model could start with a cross - section that includes both the Elm Fork and Denton Creek channels and floodplain (shown as section 99708 of the Elm Fork model created by the COE ), assuming peak to peak coincident flows and running combined Elm Fork and Denton Creek flows, then proceed upstream with Denton Creek cross - sections using only Denton Creek flows. Conditions at the constriction caused by the Gun Club road embankment need to be closely examined. If Denton Creek flows overtop the embankment, a split flow situation may result, which would reduce downstream Denton Creek flows. 3. In addition to FIS discharges, models should nun the Fully Developed landuse condition discharges per the Corridor Development Certificate (CDC) model to make sure that the proposed reclamation satisfies the City of Coppell flood plain ordinance. 4. This review only addresses the natural run (not the floodway run) of the existing landuse model. Further review of the proposed condition and existing condition floodway models is academic until the existing condition model correctly represents flow patterns in the area. We suggest that the hydraulic models be revised to properly model the existing creek confluence, before proceeding with a complete review of the submittal, and before a floodplain development permit and a Corridor Development Certificate are considered. Please call our offices at 214- 346 -6220 or 214 - 346 -6226 if we can be of further help or if you have any questions. Sincerely, HALFF ASSOCIATES, INC. Walter E. Skipwith, P.E.

I have the following comments, some of which are the same as previously made: • Geometry for sections 3 through 12 should end at the gun club road embankment. The only section that appears to do this is section 7. If you Include geometry along the embankment in the backwater model section, you are counting this conveyance twice, once due to the spilt flow by weir and once in the GR data for the backwater computation. • The starting WSEL for the Ultimate Condition Discharge model Is the same as for Existing Conditions • Denton Creek channel "n" value seems low considering meanders, etc. The FEMA model has a 0.060 for the Elm Fork channel in this area. The Denton Creek FEMA model reflects the straightened, enlarged channel constructed for the Vista Ridge Flood Plain Reclamation pro'ect. • The first weir at section 12 needs better definition. It looks to me as it 950 should be elev. 458 + / -, with a 451.1 occurring at 600 or 700. This will tend to reduce the flow split at this location. I recommend that you make the changes that you feel are appropriate based on these comments and your direction from the City of Coppell and proceed with proposed conditions modeling before you resubmit, in an effort to save time. Please call me if you have any questions.

Box 478 Coppell, Texas 75019 Re: Request for Fourth Review of Analysis of Denton Creek, City of Coppell, Texas Dear Mr. Griffin: As per Walter Skipwith's E -Mail of October 12, 1998 (attached), we have completed another analysis of Denton Creek for the 100 -year existing and ultimate flows. As with our first submittal, we have provided only the existing condition 100 -year. We are aware that the final report must address project conditions, storage requirements and all the other elements of submittal of a Conditional Letter of Map Revision. We have provided two models both in hard copy and on disk. File DES represents the existing condition analysis for the 100 -year analysis with existing flows, and file DESUI represents the existing condition analysis for the 100 -year analysis with ultimate flows. We will send a copy of this information to the City and Halff and Associates via Lone Star Overnight. We are available to discuss this at any time.

Unfortunately, I was out of town Thursday and Friday. However, I hays made a quick w4ew of the Existing model- Future Discharges and have the following comments: " Discharge reduction due to split low should begin at section 12 " Sections 13 and 14 should be evaluated for full low (no reduction due to split) " Geometry for sections 3 through 12 should end at the gun club embankment. If you include top of embankment along the embankment In the backwater model section, you are counting this conveyance twice, due to the split low by weir " Section 14 bank stations are wrong ' I recommend adding t or 2 sections between Section 1 and 2 Denton Creek channel "n" value seems low considering meanders, etc. ' The Irst weir at section 12 needs better definition. it looks to me as if 950 should be elev. 458+/ -, with a 451.1 occurring at 600 or 700. This will tend to reduce the low split at this location. Please call me if you have any questions.
