Introduction REQUEST FOR A LETTER OF MAP AMENDMENT COPPELL ROAD SENIOR CITIZENS CENTER 1. General. This study was undertaken to provide the necessary technical data for issuance of a FEMA Letter of Map Amendment (LOMA) for a single lot along Stream 13-1, a tributary of Grapevine Creek, in the City of Coppell, Texas. The required forms for this "Request for a Letter of Map Amendment" are included in Section II of this report. 2. Site description. Stream 13-1 is a tributary to Grapevine Creek which drains generally in an easterly direction within the City of Coppell and eventually flows to its confluence with Grapevine Creek approximately 2500 feet downstream (east) of the site. The lot is the property of the City of Coppell and is located on the south bank of Stream 13-1 about 300 feet north of the intersection of Coppell Road and Bethel Road (previously known as Bethel School Road). It is currently occupied by a fire station, a water tank and storage buildings. None of the existing buildings have basements. The Stream 13-1 channel and banks are overgrown with trees and brush in this area. The overbanks are covered with low grass, some brush and a small amount of trees. The vicinity was subject to light urbanization in the past and used to be the center of the old City of Coppell. It has retained its charm and now consists of part large residential lots and part commercial properties. The new City of Coppell has developed tremendously in the last few years on the outskirts of this old downtown area. 3. Purpose. .~ The site isotrrently located within the FEMA regulatory flood plain. It has been assigned the zone A descriptor reserved for areas inundated by the 100-year flood but for which no base flood elevations have been determined. It is located approximately 700 feet upstream of the current limit of detailed hydrauiie study. Halff Associates, Inc. was retained by the City of Coppell to extend the effective FEMA models to include the fire station site and to determine the extent of the l O0-year flood plain based on existing landuse watershed conditions (FIS discharges) and the most recent City of Coppell aerial topography. The City of Coppell will eventually convert the existing fire station into a senior citizens center. Channel or flood plain / floodway alterations are not planned as a part of the project. 4. Data collection. The hydrology for Stream 13-1 was not updated for this study and the revised (extended) hydraulic models use discharges similar to the ones used in the effective FIS model. The hydrology was judged appropriate for the 1035 foot stretch of channel upstream of the current detailed study. The original hydrology was developed by Goodwin and Marshall, Inc. in 1992 as part of a LOMR approved by FEMA on October 16, 1992 (case number 92-06-124P). Work maps for this project are based on City of Coppell topographic maps prepared in 1995 by Dallas Aerial Surveys. 5. Hydraulic analysis. · Existing Conditions. The effective FIS model was extended using cross-sections from the City-Wide Storm Water Management Study performed by Halff Associates, Inc. for the City of Coppell in January 1991. The five added cross sections span 1035 feet of channel. The model now extends to a point 55 feet upstream of the Coppell Road culvert. Additionally, at cross section 3675, the channel and right overbank geometry was modified per a HalffAssociates, Inc. March 1996 field survey. The new cross sections have higher n-values than those present at the upstream end of the effective FEMA model. Those higher values are identical to those used in the City-Wide Storm Water Management Study and are justified by the abundance of vegetation in the area. Manning's n-values were not modified downstream of the added cross sections. Floodway Determination. The current effective FEMA FIRM includes a floodway delineation for Stream G-1 along all of its study reach, from its confluence with Grapevine Creek to the upstream limit of the detailed study. However, the purpose of this report is to establish base flood elevations at a specific structure. Therefore, the floodway model was not modified to include this additional segment of the creek. 6. Hydraulic Results. The revised 100-year flood plain delineation results in a total flood plain area decrease of 3.30 acres upstream of the current limit of detailed study. The only crossing in the extended reach is that of the Coppell Road box culvert, which would be submerged in the event of a 100-year flood. Flow velocities at the added cross sections are all in the non-erosive range (less than 6 fps.) except at the upstream face of the culvert (cross section 4550) where the existing ehaunel is armored with concrete. The results of this study show that the existing building would not be included in the 100-year flood plain when delineated on the effective City of Coppell topographic map. While the main building's finished floor is at elevation 509.2, the outside comer of the same structure is at elevation 508.1 and the water surface elevation at the same location is at elevation 506.0. 7. Benchmarks. The Halff Associates, Inc. March 1996 field survey attempted to tie the FIS elevation reference mark RM 196 described on the FIRM as "RM 196, elevation 467.22, chiseled square on top of wheel guard at southwest corner of bridge of Denton Tap Road over Cottonwood Branch OVGVD 1929)". A wheel guard could not be found at that location but a chiseled square cut mark was found nearby on the SW comer of the Denton Tap Road bridge over Cottonwood Branch (outside edge of concrete mil), approximately 400 feet north of Parkway Boulevard. That mark was fled at elevation 466.93. 1-2 The same survey tied the FIS elevation reference mark RM 197 described on the FIRM as "RM 197, elevation 483.50, chiseled square on top of wing wall SE corner of bridge on Sandy Lake Road over Cottonwood Branch (lqGVD 1929)" at elevation 483.80. The Halff Associates, Inc. survey used the highly accurate global positioning system (GPS) in its determination of the benchmarks' elevation. GPS observations were constrained horizontally to the High Accuracy Regional Reference Point in Arlington, Texas. The GPS network was adjusted vertically to the US Coast and Geodetic Benchmark 7Y-1924-R35 (3rd order) at the Elm Fork dam on Sandy Lake Road (elevation 438.531, NGVD29), 8. Photographs.

The summary must includ~ a complete description of any changes made from model to model (e.g. duplicate effective model to corrected effective model). At a minimum, the Duplicate Effective (item 1) and the Revised or Post-Project Conditions (item 4) models must be submitted. See instructions for directions on when other models may be required. See L Introduction, $. Hydraulic analysis, page I-2 For areas which do not have detailed flooding: Only the 100-year flood profile is required. A hydraulic model is not required for areas which do not have detailed flooding; however, BFE's may not be added to the revised FIRM. If a hydraulic model is developed for the area, items 3 and 4 descn~c~l below must be submitted. If hydraulic models are not developed, hydraulic analyses for existing or pre-project conditions and revised or post-projeot conditions must be submitted.

Explain how reach lengths for channel and overbanks were determined: Reach lengths_for inserted sections were taken_from the CRv_ of Coppell's 1991 Cl~_ -Wide Storm Water Management St_u_~v model: The reach length between cross section 3675 and cross section 3515 (the transition between the ~f-fective model and the Ci(v_ 's model) was sc_n_led from the Ci~_ o_f Coppell's aerial topograp_ hlc map. 5. RESULTS (from model used to revise l O0-yeur water surface elevations) 1. Do the results indicate: a. Water surface elevations higher than end points of cross sections? b. Supercritical depth? c. Critical depth? [] Yes I~ No [] Yes [] No Cl Yes [] No [] Yes [] No d. Other unique situations? Hydraulic jump occurs downstream of submerged culvert If yes to any of the above, attach an explanation that discusses the situation and how it is presented on the profiles, tables and maps.

What is the maximum surcharge allowed by the community or State? IV/A foot b. What is the maximum surcharge for the revised conditions? Specify location lg/A fps N/A c. What is the maximum velocity? Specify location d. Are there any negative surcharge values at any cross-section [] Yes [] No If yes, the floodway may need to be widened. If it is not widened, please explain and indicate the maximum negative .surcharge. Explain: Riverine Hydraulic Analysis Form ii-a MT-2 Form 4 Page 4 of 6 RESULTS (Cont'd) Is the discharge value used to determine the floodway anywhere different from that used to determine the natural 100- year flood elevations? [] Yes [] No N/A If yes, explain: 7. Do 100-year water surface elevations increase at any location? [] Yes [] No If yes, please attach a list of the locations where the increases occur, state whether or not the increases are located on the requester's property, and proyide an explanation of the reason for the increases. (For example: State if the increase is due to fill placed within the floodway fringe or placed within the currently adopted floodway limits) Please attach a completed comparison table entitled: Water Surface Elevation Check (See page 6) ,4iso see Attachment 4-B, Tables 6. REVISED FIRM/FBFM AND FLOOD PROFILES The revised water surface elevations tie into those computed by the effective FIS Model (10; 50,100-, and 500-year), downstream of the project at cross-section 3675 within 0.0 feet (vertical) and upstream of the project at cross section N/A within N/A feet(vertical). N/A, the purpose of this LOMA is to extend the FI$ ~del u~strean~ B. The revised floodway elevations tie into those computed by the effective FIS model, downstream of the project at cross section N/A within N/A feet (vertical) and upstream of the project at cross section N/A within N/A feet (vertical). N/A, the effective floodway does not extend to the revised arem C. Attach profiles, at the same vertical and horizontal scale as the profiles in the effective FIS report, showing stream bed and profiles of all floods studied (without encroachment). Also, label all cross sections, road crossings (including low chord and top-of-road data), culverts, tributaries, corporate limits, and study limits. If channel distance has changed, the stationing should be revised for ali profile sheets. See Figure 9, Appendix ,4. D.

DALLAS COUNTY, TEXAS 15 strength of the soil are limitations to urban uses. These ,=,limitations can be overcome through good design and careful installation. Areas that have trees are desirable for residential development. This soil is in capability subclass Ills and in the Clay- ,., pan Savannah range site. 11--Axtell fine sandy loam, I to 3 percent slopes. This is a deep, gently sloping, moderately well drained ,-soil on old high stream terraces. The areas are oval to long and narrow and range from 10 to about 100 acres. Typically, the surface layer is slightly acid, dark grayish brown fine sandy loam about 4 inches thick. To a depth -' of 8 inches, the soil is slightly acid, very pale brown fine sandy loam, and to a depth of 39 inches, it is very strongly acid clay that is mottled in shades of brown, red, and gray. To a depth of 52 inches, the soil is medium "' acid, grayish brown clay that has red and brown mottles. To a depth of 80 inches, it is moderately alkaline, grayish brown sandy clay. Permeability is very slow, and the available water ca- "pacity is high. Runoff is medium, and the hazard of erosion is moderate. Included in mapping are small areas of Crockett, Mabank, Silawa, and Rader soils. The included soils '-make up less than 20 percent of any one mapped area. This soil is used mainly as pasture, for which it has medium potential. Forage production is high if the pas- ,.. ture is properly managed. This soil is well suited to ira- proved bermudagrass. This soil has Iow potential for use as cropland. The hazard of erosion and, in most areas, the Iow fertility of the soil are limitations. Terraces and ,. contour farming help to control erosion. Crop residue should be left on the surface to help conserve moisture and to maintain tilth and productivity. This soil has medium potential for urban development. --The high shrink-swell potential, Iow strength, and corrosi- vity of the soil and the hazard of erosion are limitations, but they can be overcome through good design and careful installation. Areas of this soil that have trees are -' highly desirable for residential development. This soil is in capability subclass Ille and in the Clay- pan Savannah range site. 12--Axtell fine sandy loam, 2 to 5 percent slopes, eroded. This is a deep, moderately well drained soil on old high stream terraces. The areas are oblong to long and narrow and range from 10 to about 50 acres. Gullies --are common in all areas, and subsoil material is exposed in about 30 percent of the areas. Between the gullies, sheet erosion has removed as much as 40 percent of ,.. the surface layer. Typically, the surface layer is medium acid, dark gray- ish brown fine sandy loam about 4 inches thick. To a depth of 19 inches, the soil is strongly acid, dark brown _ clay loam. To a depth of 35 inches, it is mottled, light yellowish brown and yellowish red, strongly acid clay. The next layer, to a depth of 80 inches, is medium acid clay that has yellow and gray mottles. Permeability is very slow, and the available water ca- pacity is high. Runoff is medium, and the hazard of erosion is severe. In most areas, the organic matter content is Iow because erosion has removed material from the surface layer. Included in mapping are small areas of Crockett, Rader, and Silawa soils. The included soils make up less than 20 percent of any one mapped area. This soil is used mainly as pasture, for which it has medium potential. It is well suited to improved bermuda- grass. This soil has Iow potential for use as cropland. The Iow fertility, very slow permeability, and poor tilth of the soil and the hazard of erosion are limitations to crop production. Establishing close-growing crops helps to control erosion. Leaving crop residue on the surface of the soil helps to control erosion, conserve moisture, reduce soil temperature, and maintain tilth and productiv- ity. This soil has medium potential for urban uses. The high shrink-swell potential, Iow strength, and corrosivity of the soil and the hazard of erosion are limitations, but they can be overcome through good design and careful installation. This soil is in capability subclass IVe and in the Clay- pan Savannah range site. 13--AxtelI-Urban land complex, I to 5 percent slopes. This complex is made up of deep, gently slop- ing, moderately well drained soils and areas of Urban land on uplands. The areas are oblong or oval and range from about 20 to 70 acres. The Axtell soil makes up about 50 percent of this complex, and Urban land, which consists of areas cov- ered with buildings, streets; and pavement, makes up about 25 percent. The rest of the complex is made up of minor soils. These soils and Urban land are so intermin- gled that it was not practical to separate them in map- ping at the scale used. Typically, the surface layer of the Axtell soil is slightly acid, dark grayish brown fine sandy loam about 4 inches thick. To a depth of 8 inches, the soil is very slightly acid, pale brown fine sandy loam, and to a depth of 39 inches, it is very strongly acid clay that has brown, red, and gray mottles. To a depth of 52 inches, the soil is medium acid, grayish brown clay that has red and brown mottles. To a depth of 80 inches, it is moderately alka- line, grayish brown sandy clay. Permeability of the Axtell soil is very slow, and the available water capacity is high. Runoff is medium, and the hazard of erosion is moderate. Included in mapping are small areas of Crockett, Mabank, Rader, Silawa, and Wilson soils. The included soils make up less than 25 percent of any one mapped area. The soils in this complex have medium potential for urban uses. The high shrink-swell potential, Iow strength, and corr0sivity of the soil and the hazard of erosion are limitations, but these limitations can be overcome through good design and careful installation.

The soil in these horizons is neutral to moderately alkaline. In some pedons, there are soft lumps of calcium carbonate. Bastsil series The Bastsil series is made up of deep, well drained, nearly level to gently sloping loamy soils. Bastsil soils formed in old alluvium on old high stream terraces. The slopes range from 0 to 3 percent. Typical pedon of Bastsil fine sandy loam, 0 to 3 per- cent slopes; from the intersection of Interstate Highway 635 and U.S. Highway 175, this pedon is located about 1 mile.north on Interstate Highway 635 to Seagoville Road, 1,300 feet east on Seagoville Road, 600 feet south on Carolyn Jean Drive, and 300 feet southwest in a pasture within the Balch Spdngs city limits: ApO to 8 inches; brown (10YR 5/3) fine sandy loam, dark-brown (10YR 4/3) moist; weak coarse blocky structure; hard, friable; medium acid; clear smooth boundary.

The Bt horizon is sandy clay loam that is 18 to 35 percent clay. It is red, reddish brown, reddish yellow, yellowish red, or strong brown, and the soil is medium acid to mildly alkaline. The B23t horizon is clay loam or sandy clay loam. The Bastsil soils in this survey are taxadjuncts to the Bastsil series because they do not have secondary elu- viation (skeletans and clean sand grains) in the lower part of the Bt horizon; however, they are similar in use and management to the soils of the Bastsil series. Brackett series The Brackett series is made up of shallow, well drained, loamy soils. Brackett soils formed in material that derived from soft chalky limestone. The slopes range from 3 to 25 percent. Typical pedon of Brackett loam, 3 to 5 percent slopes; from the intersection of Camp Wisdom Road and Cock- rell Hill Road, this pedon is located 3,700 feet east on Cockrell Hill Road and 2,400 feet north in a pasture within the Dallas city limits: Al--0 to 9 inches; light brownish gray (10YR 6/2) loam, dark grayish brown (10YR 4/2) moist; moderate and strong very fine granular and subangular blocky structure; hard, friable; abundant roots and worm casts; few shell fragments; calcareous; moderately alkaline; clear smooth boundary.

Cr1--16 to 23 inches; weakly fractured soft chalky lime- stone, about 25 percent very pale brown (10YR 7/3) loam in horizontal and vertical fractures; the size and number of fractures decrease with depth; few roots and worm casts; calcareous; moderately alka- line; gradual wavy boundary. Cr2~23 to 29 inches; white (10YR 8/1) and yellow (10YR 7/6) slightly fractured soft limestone; the limestone is less than 3 on Mohs' scale of hardness. The solum is 10 to 20 inches thick. Coarse fragments in the solum range from a few small, soft limestone fragments to rounded limestone fragments less than three inches long that make up as much as 35 percent of the soil. The soil is more than 40 percent calcium carbonate. When the soil is dry, the ^ horizon is grayish brown, brown, pale brown, light brownish gray, light yellowish brown, or light gray. When dry, the B2 horizon is grayish brown, light brownish gray, light gray, brown, pale brown, very pale brown, or light yellowish brown. It is gravelly clay loam, clay loam, or loam and is 18 to 30 percent clay. The Cr horizon generally is 25 to 70 percent soft limestone fragments but can be as much as 80 percent waterworn limestone pebbles. The fine earth fraction ranges from loam to clay loam. Branyon series The Branyon series is made up of deep, moderately well drained, .nearly level clayey soils. Branyon soils formed in clayey alluvial sediment on old stream ter- races. The slopes are 0 to I percent. 142 SOIL SURVEY TABLE 18.--PHYSICAL AND CHEMICAL PROPERTIES OF SOILS [The symbol < means less than. Entries under "Erosion factors--T" apply to the ent. tre profile.
