SW0001-SY000601DELINEATION OF JURISDICTIONAL WETLANDS FOR THE PROPOSED RIVERCHASE ELEMENTARY SIDEWALK, CITY OF COPPELL, TEXAS Prepared for: THE CITY OF COPPELL ENGINEERING DEPT. _ 255 Parkway Blvd. Coppell, Texas 75019 Prepared by: Geo- Marine, Inc. Environmental Engineering Services GEO- MARINE 550 East Fifteenth Street Plano, Texas 75074 JUNE 2000 Delineation of Waters of the U.S., Including Wetlands City of Coppell, Texas 1.0 INTRODUCTION 1.1 Introduction and Organization This report presents the results of a delineation of jurisdictional waters of the United States (U.S.), including wetlands, performed for the City of Coppell, Texas. The survey was conducted to aid the city in planning the location of a sidewalk from the Riverchase Community across undeveloped open space and utility easement to Riverchase Elementary School. The report is organized as follows. • In addition to providing the organization of this report, Section 1 provides a general description of the project area and presents the regulatory authority and legal definitions relevant to delineations of waters of the U.S. • Section 2 presents the methodology used to delineate potential jurisdictional waters of the U.S. and describes the potential waters of the U.S. observed at the site. • Section 3 presents a summary of the delineation and recommendations for coordination with the U.S. Army Corps of Engineers ( USACE), if required. 1.2 General Description of the Project Area The project site is approximately 22 acres (ac) located south of Sandy Lake Road, between MacArthur Road and Riverchase Boulevard in Coppell, Texas (Figure 1, Attachment A). The site consists of approximately 10 ac of upland fill which is dominated by rye grass (Lolium perenne) and 12 ac of TXU transmission line easement dominated by sweet clover (Meliotus sp.), clasping - leaf coneflower (Dracopis amplexicaulis), and Japanese brome (Bromus japonicus). Low areas within the easement have developed native wetland plant communities. A small man -made drainage channel oriented north -south between the school and the upland fill site carries stormwater runoff from the uplands to the lower areas within the easement. - Trees on the site are limited to the areas near the drainage channel and outside of the TXU easement due to mowing and possibly chemical herbicide applications. Common trees in these sites include black willow (Salix nigra), hackberry (Celtis laevigata), cottonwood (Populus deltoides), and western soapberry (Sapindus drummondit). Soils at the site are mapped as Trinity clay, occasionally flooded, but have been heavily impacted due to filling activities in the past 25 years (U.S. Department of Agriculture [USDA] 1980). 1.3 Regulatory Background 1.3.1 Regulatory Agencies Agencies that regulate impacts to the nation's water resources within Texas include the USACE, the U.S. Environmental Protection Agency (USEPA), the U.S. Fish and Wildlife Service (USFWS), and the Texas Natural Resource Conservation Commission (TNRCC). Jurisdictional waters of the U.S. are protected under guidelines outlined in Sections 401 and 404 of the Clean Water Act (CWA), in Executive Order 11990 (Protection of Wetlands), and by the review process of the TNRCC. The USACE has the primary regulatory authority for enforcing Section 404 requirements for waters of the U.S., including wetlands. Prepared by Geo- Marine, Inc. 1 Delineation of Waters of the U.S., Including Wetlands City of Coppell, Texas 1.3.2 Definitions In 33 Code of Federal Regulations (CFR) 328.3, the USACE defines waters of the U.S. as: • All waters which are currently used, or were used in the past, or may be susceptible to use in interstate or foreign commerce, including all waters which are subject to the ebb and flow of the tide; • All interstate waters including interstate wetlands; • All other waters such as intrastate lakes, rivers, streams (including intermittent streams), mudflats, sandflats, wetlands, sloughs, prairie potholes, wet meadows, playa lakes, or natural ponds, the use, degradation or destruction of which could affect interstate or foreign commerce including any such waters: • Which are or could be used by interstate or foreign travelers for recreational or other purposes; or • From which fish or shellfish are or could be taken and sold in interstate or foreign commerce; or ■ Which are used or could be used for industrial purpose by industries in interstate commerce; • All impoundments of waters otherwise defined as waters of the U.S. under the definition; • Tributaries of waters of the U.S. identified above; • The territorial seas; • Wetlands adjacent to waters (other than waters that are themselves wetlands) identified in paragraphs (a) (1) through (6) of this section. The term adjacent means bordering, contiguous, or neighboring. Wetlands separated from other waters of the U.S. by man -made dikes or barriers, natural river berms, beach dunes and the like are "adjacent wetlands." Jurisdictional wetlands are a category of waters of the U.S. and are defined by the USACE as "areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions." Wetlands generally include swamps, marshes, bogs, and similar areas. Prepared by Geo- Marine, Inc. 2 Delineation of Waters of the U.S., Including Wetlands City of Coppell, Texas 2.0 DELINEATION OF POTENTIAL JURISDICTIONAL WATERS OF THE U.S. 2.1 Methodology Prior to conducting fieldwork, the Soil Survey of Dallas County, Texas, and an aerial photograph _ of the proposed project area were studied to identify possible waters of the U.S. and areas prone to wetland development. The project site was field checked and the delineation of potential waters of the U.S. was performed on location in accordance with the Corps of Engineers Wetlands Delineation Manual (the 1987 manual). Fieldwork was conducted on 25 May 2000 by _ James A. Thomas and Tom Trimble of Geo- Marine, Inc. Data forms were filled out for all potential wetland waters of the U.S. These data forms are — included in Attachment B. The areas of all potential wetlands were measured and their locations were noted on a field map of the site. Photos were also taken at representative points within the project area (Attachment C). 2.2 Results Jurisdictional waters of the U.S. observed on the project site consisted of one irregularly shaped 3.3 -ac wetland (see Figure 2, Attachment A). The irregular shape of the interconnected wetland may be due to past clearing or fill activities associated with the easement development in the 1970s. The wetland consists of four distinct habitat types that were characterized by different plant communities. The mosaic patterns of vegetation within the wetland were due to varying elevations and therefore hydroperiods. Wetland habitat A comprises approximately 0.5 ac of the site and is a seasonally flooded area that was inundated with 3 to 6 inches of water during the field surveys. Habitat A was dominated by cocklebur (Xanthium strumarium) and sedge (Carex crus- corvi). Wetland habitat B (0.2 ac) had a similar seasonal hydroperiod as habitat A, but the plant community was dominated by narrowleaf cattail (Typha angustifolia) and spikerush (Eleocharis palustris). Wetland habitats C and D were temporarily flooded areas, comprising 1.42 ac and 1.23 ac, respectively. Habitat C is lower in elevation and is dominated by sedge, while habitat D is the highest wetland type, dominated by a mix of wetland and facultative grasses and herbaceous species. The drainage channel was considered a non - jurisdictional feature, as it was constructed to drain upland or filled areas. There is no evidence of the drainage channel or a natural stream in this location on the 1975 aerial photography in the Dallas County soil survey (USDA 1980). Prepared by Geo- Marine, Inc. 3 Delineation of Waters of the U.S., Including Wetlands City of Coppell, Texas 3.0 SUMMARY AND RECOMMENDATIONS The area of jurisdictional wetlands on the 22 -ac project site is approximately 3.3 ac. The wetlands vary from seasonally flooded habitats (A and B) to temporarily flooded areas (C and D). The seasonally flooded areas serve as beneficial wildlife habitat for wading birds and potentially for waterfowl for foraging and loafing sites. Numerous wading birds (egrets and herons) and passerine species were identified in habitat A during the field surveys. There were no non - wetland jurisdictional waters of the U.S. identified on the site. A non- jurisdictional drainage channel (man -made) was identified along the western boundary of the study area. The proposed sidewalk route should be determined using this delineation to avoid and /or minimize impacts to the wetlands on the area. 3.1 Section 404 Permits and Notification Requirements Activities considered impacts to wetlands and other waters of the U.S. would include filling, draining, channelization, bridge crossings, and use of machinery inside the ordinary high water mark (OHWM) of delineated areas. Permits for impacts to jurisdictional waters of the U.S., including wetlands, include Nationwide Permits (impacts up to 1/2 ac or less than 300 linear feet) and Individual Permits (impacts to greater than 112 ac or 300 linear feet). If project impacts would be less than 1/10 ac or 300 linear feet, a pre- construction notification (PCN) to the USACE is not required. However, if project impacts are greater than 1/10 ac or 300 linear feet, a PCN is required and special conditions, such as compensatory mitigation, may be necessary to receive a Section 404 permit. 3.2 Recommendations The proposed sidewalk project could be completed under the revised Nationwide Permit 14 (effective June 7, 2000) without requiring a PCN if the impacts to wetlands are less than 1/10 ac. Geo- Marine, Inc. has provided a sample analysis of a sidewalk route from Bradford Drive to Riverchase Elementary. Assuming a 20- foot -wide impact corridor for the sidewalk, the sample route would only impact approximately 0.03 ac of wetland habitat D. This would be considered minor impacts to a temporarily to ephemerally flooded wetland and could be completed under the Nationwide Permit 14 (Linear Transportation Projects) without requiring a PCN to the USACE Regulatory Branch. Additional routes around the north or south sides of the wetlands could also be chosen without impacting any jurisdictional wetlands. However, Geo- Marine, Inc. feels the sample route is the - most direct route possible with only minor impacts to the wetlands. If a route is chosen which impacts greater than 1/10 ac, this delineation and a formal PCN should be submitted to the USACE Regulatory Branch in Fort Worth.
