SCOPE OF WORK

FOR

PLEASANT RUN ROAD IMPROVEMENTS ENGINEERING SERVICES

PROJECT NUMBER: 31403

SEWER LINE FINAL DESIGN, BID, AND CONSTRUCTION ADMINISTRATION SERVICES

BACKGROUND

AECOM was authorized on May 131h 2014 to perform preliminary engineering services for

improvements to Pleasant Run Road from Lancaster-Hutchins Road to Millers Ferry Road, approximately a three-mile stretch. The project includes a Preliminary Engineering Report (PER) and the preparation of 30% roadway, drainage, water and sewer plans. Dallas County requested that additional services be included as an amendment to the contract to advance the design of the roadway, drainage and sewer line plans from previously contracted 30% level to final design, so that this portion of the project can be constructed by a selected contractor. Work Order #5 (W0#5) was prepared to finalize the roadway and sewer plans. During preliminary design phase for a segment of the Wilmer sewer line for W0#5, it was noted that the preferred route during the study phase could not be constructed due to ROW issues. Thus, an alternate alignment is required for the sewer line. The effort to realign the sewer line will be covered by this project design proposal and provides a study and design services for the Wilmer sewer line. Services for this project design proposal will generally include:

• Sanitary Sewer Alignment Study- AECOM reviewed different options to re-align the sewer line along Cottonwood Creek. The review accounted for the profile of the sewer based on 2-ft contour mapping from the NCTOG. A review of sewer depths, ROW, and aerial crossing locations allowed for one defined option. The selected option was agreed upon in meetings and will be taken to Final Design.

• Sanitary Sewer Line Final Design -Bidding documents for 4,200 LF of new sewer line to serve Wilmer along Cottonwood Creek, as presented in meetings and depicted in the Final PER, wh ich was developed through the Sewer Alignment Study. It should be noted that W0#5 Contract included the design of 2,400 LF of sewer along Cottonwood Creek. Thus, the 2,400 LF will not be included in this scope. This scope provides for the difference between the two proposals, which is 1,800 LF, and the design of two aerial crossings.

The following document is a detailed scope of work for the services. Compensation for these services will be based on prim e contract, paid on a percent to complete basis as a lump sum base contract, with the exception of Special Services, paid as Time and Materials.

Natural Resources Assessment

The objective of the natural resources assessment is to identify environmental resources in order to complete the NCTCOG RTR checklist. As such, the following services are to be included as part of this scope.

SCOPE OF SERVICES:

I. Water of the U.S./ Wet land Survey (Stream Cross ings)

• • • •

•

A waters of the U.S./wetlands survey will be conducted along the project corridor. If waters of the U.S. and/or wetlands are located along the ROW, they will be delineated in accordance with the 1987 Corps of Engineers Wetlands Delineation Manual and the appropriate regional supplement. In addition, information regarding the location and size of stream crossings and whether any permits are needed wi ll be provided.

The U.S. Corps of Engineers (USACE) regulates "Waters of the U.S.", wetlands and special aquatic sites under Section 404 of the Clean Water Act (CWA) and Section 10 of the Rivers and Harbors Act. The USACE and the Environmental Protection Agency (EPA) define wetlands as "those areas that are inundated or saturated by surface or groundwater 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 typically include swamps, marshes, bogs, and other similar areas".

Prior to conducting the environm ental field activities, we will perform a desktop review of the project area by reviewing the following sources:

U.S. Geological Survey (USGS) 7.5-minute topographic quadrangle maps; U.S. Fish and Wild life Service (USFWS) National Wetlands Inventory (NWI) Maps; Aerial photographs (current and historical); U.S. Department of Agriculture (USDA), Natural Resources Conservation Service (NRCS) County Soil Surveys; and Federal Emergency Management Agency (FEMA) Flood Hazard Maps .

The desktop review will assist in the planning and execution of the field surveys and will expedite the field survey process.

Surveys will be performed by tra ined biologist using common wetland survey tools such as shovels and soil augers, the Munsell Soil Color Chart, Wetland Data Forms, plant indicator lists, and visual observation for plant identification. The survey will implement the three parameter approach, assessing vegetation, soils, and hydrology for wetland conditions, as set forth in the 1987 Corps of Engineers Wetlands Delineation Manual and the regional supplement to determine the boundaries of potential wetlands within the survey area.

Iden tified wetland boundaries will be surveyed using Global Positioning System (GPS) technologies. Stream crossings will be identified by number, name (if applicable), stream flow, ordinary high water mark (OHWM) distance in feet, and comments regarding dominant vegetation and streambed communities. Ponds will be characterized by number, description and crossing length in feet.

A summary of survey findings will be provided in electronic format. Additionally, photographic documentation of each water and/or wetland feature and representative vegetation will be provided in a Photographic Exhibit and electronic shapefiles of the collected features wi ll be presented on maps created in ArcGIS. Copies of the Wetland Data Forms will also be included with the Report. The data will include the following:

• A summary table of the qualitative data; including, • Type of water feature, • Type of vegetation cover, • Description of aquatic life, • Coward in Classification of water feature, • Significant nexus, and • Whether the feature meets a definition of a water of the United States.

• A summary table of quantitative data (e.g . length and/or area) within the survey area for each water and/or wetland feature.

II. Threatened and Endangered (T&E) Species Habitat Assessment During the waters of the U.S./wetlands survey, a field assessment for potential habitat for any T&E species wi ll be conducted and observations/recommendations regarding birds protected by the Migratory Bird Treaty Act (MBTA) will be recorded.

• U.S. Geological Survey (USGS) 7.5-minute topographic quadrangle maps; • Aerial photographs (current and historical); • U.S. Department of Agriculture (USDA), Natural Resources Conservation Service (NRCS) County

Soil Surveys; • County Lists of T&E available through the State and/or Federal Agencies; • Other relevant information as appropriate.

A paragraph summary of the habitat survey to be included in the waters of the U.S./wetlands delineation report will be prepared. In addition, we will provide a summary table of T&E/rare species along with suitable habitat descriptions, and suitable habitat presence or absence determinations within the project area for each species. Recommendations regarding MTBA birds will also be included.

Ill. Right-of-Way Information (for RTR Checklist) Complete the existing land use section of checklist. AECOM will be responsible for providing utility information and information about any structures to be displaced.

IV. Threatened and Endangered Species; Migratory Bird Treaty Act; Farmland; Wetlands; Waters of the U.S.; Water Quality; Floodplains; Vegetation; Air Quality Regulated Materials (for RTR Checklist)

The information gathered in Sections I and II above will be used to complete these sections. Desktop resources and information provided by AECOM will be utilized to complete these sections.

Cultural Resources Assessment

The objective of the cultural resources assessment is to identify and/or delineate, determine, and characterize potential archaeological sites within the proposed project corridor and the proposed area of potential effects (APE). The proposed APE for the project is not assumed to exceed 150-ft.

SCOPE OF SERVICES:

Archaeological Survey A linear pedestrian survey with associated shovel testing of the proposed APE of the project that will be impacted by the construction activities will be performed. These investigations will follow the prescribed guidelines as set forth by the Council of Texas Archeologists (CTA) and approved by the Texas Historical Commission (THC) for linear projects. Shovel tests wil l be excavated judgmentally at jurisdictional water crossings along the APE to explore for subsurface cultural deposits. The survey will be conducted by a Project Archeologist traversing the area along systematic transect intervals spaced 15 meters apart. Any archeological sites recorded during the course of the survey will be delineated by excavating shovel tests in the four cardinal directions until two consecutive negative tests are reached.

Prior to conducting fieldwork, background research on the area will be conducted including reviewing the following resources:

• The Texas Historical Commissions Archeological Site Atlas • The National Register of Historic Places Online Database

While in the fie ld, detailed notes and photographs will be taken of the general area of the project and selected shovel test units, and all archaeological sites and local ities identified. Since the location of the project is on ancient landforms, the potential for deeply buried archaeological resources is low; therefore, no backhoe trenching is recommended for this project.

Official State of Texas Archaeological Site Forms will be completed for all archaeological sites identified, and general assessments made as to the National Register of Historic Places eligibility of these resources. The proposed project APE may cross several drainages, and could have several previously unrecorded historic and prehistoric sites located along the APE. There are no previously recorded sites within a 1-mile radius of the proposed APE. It is assumed that no more than one archeological site will be encountered, since the survey crosses at least one drainage.

Once the survey is completed and all f indings are analyzed, a report summarizing the findings and recommendations will be submitted to the client for review. The reports will only need to be submitted and reviewed by the THC if any archeological sites are encountered. With concurrence, the f inal reports will be submitted to the client.
