The review included a review of background information to identify the potential presence of Section 404 jurisdictional areas (including wetlands), field reconnaissance to determine onsite conditions and collection of necessary onsite field data. Figure 1 illustrates the general location of the Canner Addition site, Figure 2 contains an aerial photograph of the study parcel and surrounding area, Figure 3 is a copy of the Dallas Count, soil survey for the site and the accompanying site plan illustrates the identified jurisdictional areas, data points and boundaries of the study area. Methodology Jurisdictional areas, which include wetlands, open waters and channels are regulated under Section 404 and 401 of the Clean Water Act. The U.S. Army Corps of Engineers (Corps) has the lead role in determining Section 404 jurisdictionality of these areas and coordinates with the Environmental Protection Agency (EPA) and other resource agencies, such as the Texas Natural Resource Conservation Committee (TNRCC) in authorizing activities in jurisdictional areas. The Carter Addition site is within the geographic area under the jurisdiction of the Fort Worth District of the Corps. The Corps is currently utilizing the 1987 Wetland Delineation Manual when certifying boundaries for Section 404 jurisdictional areas. The manual outlines the criteria used to determine if the three parameters for wetland identification; soils, vegetation and hydrology are present at a specific site. The methodology outlined in the 1987 manual was utilized in the evaluation of this parcel. The analysis included a review of the soil, hydrologic and vegetation conditions on the parcel. Various data points were developed, conditions analyzed and the results documented on the attached Corps approved data sheets. The approximate boundaries of the jurisdictional areas identified on the parcel are noted on the accompanying site plan titled, Wetland Evaluation of the parcel known as Carter Addition, Coppell, Dallas County, Texas. The locations of the various data points used in determining the status of the parcel are also noted on the site plan. The results of the evaluation for the three parameters associated with identification of wetland areas is briefly detailed in the results section of this memorandum and further summarized on the accompanying data sheets. Study Area Description The site (See Figure 2) is a w'ooded parcel that is bordered to the north by Carter Drive, to the east by Moore Road and to the south by Belt line Road and a railroad track right-of-way (ROW). The western boundary is adjacent to additional wooded land, that may be pasture. General development in the area is primarily residential sites, some with apparent horse pastures. Residential densities increase significantly to the north. North Lake and a Texas Utilities electrical generation plant are located to the south of the site. The site is located within a tree covered parcel associated with Grapevine Creek. The Carter Addition parcel is bisected in an east-west direction by the meandering channel of Grapevine Creek. The creek channel is incised several feet or more throughout the parcel. Surface elevations, outside of the creek channel, range from approximately 454 feet mean sea level (MSL) along the creek to approximately 480 feet (MSL) in the northeastern corner of the parcel. In general, the parcel is fiat to gently sloping except around the channel and in the extreme northern portion of the site. The majority of the site appears to be an upper level terrace of Grapevine Creek. Grapevine Creek is an apparent perennial stream that flows from the west across the central portion of the site before crossing under Moore Road. A small channeled drainage crosses under the railroad track approximately 300 feet west of Moore road and discharges to the creek. The area on the northern side of the creek channel has several small buildings or structures scattered through-out the site. A pedestrian bridge crosses Grapevine Creek in the western portion of the study area. The majority of the site is tree-covered with primarily mature hardwoods. There is minimal secondary growxh and the herbaceous cover is primarily grass. The majority of this area appears to be maintained and may be used as a campgrounds or for other large-group outdoor activities. The area on the southern side of the creek is more heavily wooded and contains a significant understudy growth. Canopy cover is tighter, although the species are similar. Understory is thicker and consist primarily of low brush, vines and sapling trees. No significant growth of herbaceous species, ~vith the exception of isolated stands of graminoid and ruderal vegetation was noted. Results of Jurisdictional Evaluation A brief description of each of the three parameters evaluated is presented below and further summarized on the accompanying data sheets. It should be noted that because of the similarity of the area on the south side of the creek Data Sheet NL4 refers to two points -- one on the west end of the parcel and one on the east end of the parcel. So//~ The parcel is mapped as containing Frio silt5' clay in the northern portion of the site and Silawa fine sandy loam to the south of the creek near the railroad tracks (See Figure 3). The Frio series is a dark gray/brown silty clay formed on level to nearly level floodplains that experience infrequent inundation. The soil is deep and well-drained. The Silawa soil is a neutral brown colored loam formed in upland areas on gentle to moderate slopes. It too is a well-drained deep soil. Neither soil is noted on the National List as a hydric soil. Field observations revealed soil profiles consistent with the typical profiles for the two mapped soils. The southern wooded portion of the site appears to contain the Silawa loam and the terrace areas adjacent to the stream channel contain the Frio clay. No field indicators of hydric soils were noted during the evaluation Hydrology The majority of the parcel is at least four feet above the water level of the stream. No visible indications of frequent inundation or soil saturation were noted. The depth to high water table in this area is reported to be greater than six feet. The field evaluation was conducted within 36 hours of a significant precipitation event and while all soil samples were wet in the upper portions several were dry at approximately six to ten inches. While several small areas of standing water were noted, they appeared to be in response to the recent precipitation. No indication of prolonged inundation or saturation was noted. It does not appear that the areas are inundated or saturated for a sufficient duration to meet the 12 percent of the growing season parameter required for wetland hydrology. Vegetation The majority of the site is vegetated with a relatively mature gro~xh of hardwood trees including several species of elm (Uhnus spp.), ash (Fraxinus spp.), and an occasional pecan (Carya spp.) and oak (Quercus spp.). The northern side of the creek is mowed and maintained as a camp or equestrian area and contains minimal secondary growth. The southern side of the creek is not maintained and contains a higher content of secondary growth including sapling trees and numerous woody shrubs. The creek channel is not vegetated and the steep banks are barren. No areas of dominate hydrophytic vegetation were identified during the field reconnaissance. No wetlands were identified ~vithin the Carter Addition parcel. The channel of Grapevine Creek, below the "ordinary high water mark" is considered a jurisdictional area (a "water of the US"). This area is depicted on the plan -sized graphic titled Wetland Evaluation of the parcel known as the Carter Addition, Coppeli, Dallas County, Texas included with this technical memorandum.. The plan also locates the data points described in the attached data sheets, the parcel boundary and the proposed activity. Summary The Grapevine Creek channel is considered a water of the US and is therefore subject to regulation by the U.S. Army Corps of Engineers and Texas Natural Resource Conservation Committee under Sections 404 and 401 of the Clean Water Act.. No other jurisdictional areas (wetlands, channels or special aquatic sites) were identified during the field reconnaissance. Activities undertaken ~vithin the boundaries of the creek channel will require authorization from the Corps and TNRCC. Activities outside of the depicted boundaries are not subject to authorization by the Corps under Section 404 of the Clean Water Act and require no Section 404 permit action. Based on the plans provided and verbal descriptions in the field it appears that the proposed activity (construction of a swale and filling of the apparent 100-year floodplain)will not require a Section 404 permit authorization.
