Halff Associates, Inc. has been working with the City of Coppell, Catellus Development Corp. and Michael Baker Jr. (MBJ), the Technical Evaluation Contractor, for our area to complete the final Letter of Map Revision (LOMR) for the recently constructed Grapevine Creek drop structure. The channel improvements downstream of this structure were built over 10 years ago, however a LOMR was not issued because of unstable channel conditions at the transition back to the natural channel. A drop structure to help control erosive velocities has been constructed and the required technical data for the final LOMR was submitted to MBJ in October 1991. This data has been reviewed and approved by Michael Baker Jr., Inc. To complete issuance of this Final LOMR, MBJ is preparing a 1000 scale map showing the correct channel configuration and the drop structure location. In preparing this map they have found that the Coppell City Limits on the new (1991 Preliminary) FIS maps does not match the drop structure location (±200 feet off) shown on the maps included with the LOMR report. This structure is only approximately 20 feet downstream of the corporate limits so any shift in this line makes it appear that the structure is not within the City of Coppell. Figure 5 and Sheet GP -1, enclosed, show where this boundary should fall in relation to the drop structure. Based on our review of this problem, it appears that the boundary shown on the preliminary FIS map dated December 16, 1991 is drawn approximately 200 feet off. A copy of the 12 -91 FIRM is included with this package. The corrected city limit line is shown in red on this copy. This discrepancy may also be noted by comparison to the city's street map (copy also attached). We understand that the City of Coppell recently submitted a formal appeal regarding additional information for the FIS update. This boundary was not specifically addressed in that submittal. Halff Associates respectfully requests that this boundary discrepancy be included in your review of the data submitted by the City of Coppell on June 4, 1992. Copies of all maps discussed along with a copy of Ordinance No. 86 -358 which annexed this property along IH635 are included with this letter.

Halff Associates, Inc. is addressing the following comments from FEMA as provided by their February 3, 1992 data request (copy attached). 1) Evidence of compliance with NFIP Regulation Part 65.7(b)(1) requiring public notification of a floodway change. Public Notice was published in the February 21, 1992 issue of the Citizens' ,4dvocate, Vol. VIII, No. 7, the official newspaper of the City of Coppell. A copy of this notification along with the required certification from the newspaper is attached. 2) Evidence of compliance with NFIP Regulation 65.6(a)(12) requiring documentation on how the flood - carrying capacity of the channelized portion of Grapevine Creek is to be maintained. This issue was discussed with Mr. Matt Miller, FEMA, in September 1991, prior to submission of this request for a Final Letter of Map Revision. He stated that the city is ultimately responsible for the maintenance of relocated channels. NFIP Regulation 44CFR 60.3(b)(7) requires communities to "assure that the flood carrying capacity within the altered or relocated portion of any watercourse is maintained." Ordinances which allow the city to enter upon private property and perform necessary maintenance are provided routinely in many cases. The City of Coppell's Erosion and Sedimentation Control and Nuisance Control Ordinances provide for abatement by the city. A letter to this effect, from Mr. Steven G. Goram, Director of Public Works, along with the applicable ordinances is included with this submittal.

Halff Associates, Inc. feels that this comment has been addressed extensively during the 10 year period since this channel project and Freeport Parkway were constructed. This project was built in 1981 without submission to the Federal Emergency Management Agency for a Conditional Letter of Map Revision. Since Halff Associates became the engineer for this property (1985), the existing channelization and bridge have been submitted to FEMA at least 4 times. The active conditional letter (Case No. 86- 06 -47R) specifically states that "the drop structure that is proposed between the completed channel modification and the Freeport Parkway bridge would appear to create stable channel conditions during flood events" (copy included with this package). Although the structure was moved downstream because of the IH635 right -of -way there was no increase in velocity over those shown in the hydraulic modeling for the conditional letter (see Table 1). In addition, copies of the boring logs for two locations along Grapevine Creek are included for your information. These logs indicate the soils are high to medium PI silty clays. The City of Coppell's criteria is a maximum velocity of 8 fps for unlined channel sections such as this.
