INTRODUCTION The purpose of this report is to apply for a Letter of Map Revision for the subject property, proposed Copperstone subdivision. 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. Floodplain Analysis of Cottonwood Branch In order to stay within the new requirements of the City of Coppell 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 1 & 2 have been created 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. Floodway Analysis 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 of Cottonwood Branch than the northside (sections 34075 & 34472). 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. Floodplain Analysis of Denton Creek The water surface 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 well below the levels established by the CLOMR. 4 D. Floodway Analysis of Denton Creek The floodway elevations for Denton Creek are shown in Table 2. The Revised or Post-project conditions model indicate n0 increase over the effective model and remain below the levels established by the CLOMR with the exception of section 36970. E. Parkway Boulevard Bridge 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 Coppell, Texas 75019 Case No.: 89-06-06R Dear Mayor Duggan: This is in reference to a letter dated October 10, 1988, and a floodplain study submitted by Mr. Russell R. Doyle, P.E., City Engineer for the City of Coppell. In his letter, which was forwarded to us by our Region VI office, Mr. Doyle requested a conditional Letter of Map Revision (LOMR) 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, dated October 1988, prepared by Jerry Parche Consulting Engineers, included the following: a description of the methodologies used; HEC-2 models of Denton Creek and Cottonwood Branch representing existing and proposed conditions; and delineations of the existing and proposed 100-year floodplain boundaries and the proposed regulatory floodway boundaries on a topographic map. Prior to the commencement of our review, we received the initial fee of $350.00 for processing a conditional LC~4R request of this type. This fee was sufficient to cover the review and processing costs associated with this submittal. As explained in the submitted floodplain study, additional cross sections were inserted into the HEC-2 models for Denton Creek and Cottonwood Branch (in the vicinity of Denton Tap Road), which are 'not reflected in the preliminary Flood Insurance Study (FIS) for the City of Coppell, dated September 22, 1988. These models are therefore the best available models and will be used as the new baseline models in order to evaluate the effects of the proposed project. It is important to note, however, that these submitted models incorporated a swale construction and floodplain fill project known as the 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 this project as specified under'Part 65.6 (a)(12) of the National Flood Insurance Program (NFIP} regulations. Therefore, the preliminary FIS 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 that the .proposed fill project meets the minimum floodplain management criteria of the NFIP. If the project is completed as proposed, the 100-year water-surface elevations of Denton Creek would remain unchanged except at cross section 34850 where an increase of 0.1 foot would occur. In addition, the 100-year floodplain and regulatory floodway of Denton Creek would be decreased as indicated ia the submitted floodplain study. Also, if the project is completed as proposed, the 100-year water-surface elevations of Cottonwood Branch would increase (a maximum of 0.9 foot) and the 100-year floodplain and regulatory floodway would be modified as depicted in the submitted floodplain study. It is important to note that the increase in the 100-year water-surface elevations of Denton Creek and Cottonwood Branch are due to the placement of fill outside of the regulatory floodway of each stream. Please note that future revisions to the Flood Insurance Rate Map (FIRM) and Flood Boundary and Floodway Map (FBFM) or restudies of the flood hazards in this area could modify this determination. This determination is based on the 100-year flood discharges computed in the preliminary FIS for your community, and does not consider subsequent changes in watershed characteristics that would tend to increase flood discharges. The development of this project and other projects upstream could result in increased flood discharges, which, in turn, could result in increased 100-year flood elevations. Future restudies of your community's flood hazards would take into account the cumulative effects of development on flood discharges, and could therefore establish higher 100-year flood elevations in this area. This conditional LOMR is based on minimum floodplain management criteria established under the NFIP. Your community is responsible for approving all proposed floodplain developments, including the project upon which this request is based, and for assuring that necessary permits required by Federal or State law have been received. State ahd community officials, based on knowledge of local conditions and in the interest of safety, may set higher standards for construction or may limit development in floodplain areas. If the State of Texas or the City of Coppell has adopted more restrictive or' comprehensive floodplain management criteria, these criteria take precedence over the minimum NFIP requirements. Please note the requirements for floodway revisions as outlined in NFIP regulation Part 65.7 (b)(1) (copy enclosed), which states that when a floodway change is proposed, a copy of a public notice distributed by the community stating the community's intent to revise the floodway, or a statement by the community that it has notified all affected property owners and affected adjacent jurisdictions must be submitted to the Federal Emergency Management Agency (FEMA). This requirement must be addressed when requesting a map revision to reflect the effects of the completed fill project. We have enclosed a copy of Part 65 of the NFIP regulations, which further describes the nature and extent of the material needed to support a request to revise an effective FIS, FIRM, and FBFM. Compliance with the criteria outlined in this document will expedite FEMA's review process, thus a~lowing the effective FIS, FIRM, and FBFM for your community to be revised' as 'appropriate, in a timely manner. 9 Should you have any questions regarding this matter, please do not hesitate to contact the Chief, Natural and Technological Hazards Division of the Federal Emergency Management Agency in Denton, Texas, at (817) 898-9127 or Matthew B. Miller of our Headquarters staff in Washington, D.C., at (202) 646-3461. Sincerely, es Division Federal Insurance Administration Enclosure cc: Mr. Russell R. ~oyle, P.E.

RIVERIN E HYDRAULIC ANALY SIS FORM Models Submitted Full input and output listings along with files on diskette (if available) ['or eac'h of the models listed below and summary of the source of input parameters used in the models must be provided. The summary must include a complete description of any changes made from model to model (e.g. duplicate effective model to corrected effective model). Only the Duplicate Effective and the Revised or Post-Project Conditions models must be submitted. See instructions for directions on when other models may be required. Only the 100-year flood profile is required for SFltAs with a Zone A designation. For areas which do not have detailed flooding, a hydraulic model is not required; however BFE's may not be added to the revised FIRM. [] Duplicate Effective Model Copies of the hydraulic analysis used in the effective FIS, referred to as the effective models (10-, 50-, I00-, and 500-year multi-profile runs and the floodway run) must be obtained and then reproduced on the requestor's equipment to produce the duplicate effective model. This is required to assure that the effective model input data has been transferred correctly to the requestor's equipment and 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. Natural Floodway [] Corrected Effective Model The corrected effective model is the model that corrects any errors that occur in the duplicate effective model, adds any additional cross sections to the duplicate effective model, or incorporates more detailed topographic in£ormation than that used in the currently effective model. The corrected effective model must not reflect any man-made physical changes since the date of the effective model. An error could be a technical error in the modeling procedures, or any construction in the floodplain that occurred prior to the date of the effective model but was not incorporated into the effective model. [] Existing or Pre-Project Conditions Model The duplicate effective or corrected model is modified to produce the existing or pre-proiect conditions model to reflect any modifications that have occurred within the floodplain since the date of the effective model but prior to the construction of the project for which the revision is being requested. If no modification has occurred since the date of the effective model, then this model would be identical to the corrected effective or duplicate effective model. [] Revised or Post-Project Conditions Model The existing or pre-project conditions model (or duplicate effective or corrected effective model, as appropriate) is revised to reflect revised or post- project conditions. This model must incorporate any physical changes to the floodplain since the effective model was produced as well as the effects of the project. When the request is for proposed project this model should reflect proposed conditions.

The ~rading and earthwork operations were monitored and tested on an intermittent basis. The testing and observation pro/ram was performed in order to form opinions regarding the contractor's general compliance with the project plans and spechqcaflom but the results do not constitute a Suarantee or warranty of the contractor's work. Soils and soil/rock mixt~.tres free from organic, deleterious materials and rocks greater than six inches max/mum dimension, were used for compacted fill material. Based on the types of soils used as fill material on the project site, the following moisture content and compaction requirements were used for compacted fill: Moisture Content: Between optimum and 5 percent above the optimum moisture content as deterrrdned by the Standard Proctor Test, ASTM D698. Relative Compaction: Between 95 and 102 percent of the max/mum dry density as determined the Standard proctor Test, ASTM D698. ~30li.'~$ · Fort Worth il Houston ~ AuStin Centex Real Estate Corporation May 11, 1994 Page Two Placement of compacted fill was monitored and field moisture density tests were performed by a representative of Maxim Engineers. Compacted flu that did not meet project specifications was rolled, moisture conditioned, scarified, mixed, recompacted, (as necessary) and retested prior to placing additional flu material Based on the information developed from our observations and testing and to the best of our lmowledge, we conclude that the earthwork at the subject project was performed in substantial accord with project plans and specifications. We are ready to continue working with you either in. additional consultations and or construction inspection and testing on this and future projects.

RIVERINE HYDRAULIC ANALYSIS FORM Models Submitted Full input and output listings along with files on digJ~ (if~,,~,ifi~b~e) for each ol'tho models listed below and summary of the source of input parameters used iht h'~ models must be provided. The summary must include a complete description of any changes made from mod~l Lo model (e.g. duplicate effective model to corrected effective model). Only the Duplicate Effective and th~ I~evised or Post-Project Conditions models must be submitted. See instructions for directions on when other models may be required. Only the 100-year flood profile is required for SFIIAs with a Zone A designation. For areas which do not have detailed flooding, a hydraulic model is not required; however BFE's may not be added to the revised FIRM. [] Duplicate Effective Model 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 be obtained and then reproduced on the requestor's equipment to produce the duplicate effective model. This is required to assure that the effective model input data has been transf*erred c-orre~tly the requestor's equipment and 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. Natural Floodway [] Corrected Effective Model The corrected effective model is the model that corrects any errors that occur in the duplicate effective mode..[, adds any additional cross sections to the duplicate effective model, or incorporates more detailed topographic information than that used in the currently effective model. The corrected effective model must no.t. reflect any man-made physical changes since the date of the effective model. An error could be a technical error in the modeling procedures, or any construction in the floodplain that occurred prior to the date of the effective model but was not incorporated into the effective modcl. [] Existing or Pre-Project Conditions Model The duplicate effective or corrected model is modified to produce the existing or pre-pro, ieet conditions model to reflect any modifications that have occurred within the floodplain since the date of the effective model but prior to the construction of the project for which the revision is being requested. If no modification has occurred since the date of the effective model, then this model would be identical to the corrected effective or duplicate effective model. [] Revised or Post-Project Conditions Model The existing or pre-project conditions model (or duplicate effective or corrected effective model, as appropriate) is revised to reflect revised or post- project conditions. This model must incorporate any physical changes to the floodplain since the effective model was produced as well as the effects of the project. When the request is for proposed project this model should reflect proposed conditions.

The grading and earthwork operations were monitored and tested on an intermittent basis. The testing and observation program was performed in order to form opinions regarding the contractor's general compliance with the project plkns and specifications but the results do not constitute a guarantee or warranty of the contractors work. Soils and soil/rock mixntres free from organic, deleterious materials and rocks greater than six inches maximum dimension, were used for compacted fill material. Based on the types of soils used as fill material on the project site, the following moisture content and compact-ion requirements v~ere used for compacted fill: · Moisture Content: Between optimtun and 5 percent above the opOmaurn moisture content as determined by the Standard Proctor Test, ASTM D695. I Relative Compaction: Between 95 and 102 percent of r. he maximum dry density as determined the Standard Proctor Test, ASTM D698. DOliOS · Fort V~orth I Houston ~l AuStin Centex Real Estate Corporation May 11, 1994 Page TWo Placement of compacted fill was monitored and field moisture density tests were pert'ormed by a representative of M~xim ~n~ineers. Compacted F-il that did not meet projec~ specifications w~s rolled, moisture conditioned, scarified, mixed, recompacted, (as necessary) and retested prior to placing additional Fill material. Based on the information developed from our observations and testing and to the best of our knowledge, we conclude that the earthwork at the subject project was performed in substantial accord with project p!ans and specifications, We are ready to continue working with you either in. additional consultations and or consmletton inspection and testing on tNs and f~rure projects.
