Stantec Consulting Services Inc. 5 of 16 <br />TO1 – Randolph-Sampson RTB PER <br /> <br />The purpose of the survey is to provide an accurate understanding of the existing site conditions for the <br />purpose of evaluating options for layout of the proposed facilities. The survey scope may be expanded <br />during the final design phase (under a separate work authorization) based on the selected alternative. <br />The survey data for the existing sewers, drains and CSO regulator structure (including weir elevations) <br />will be integrated into the updated hydrologic and hydraulic (H&H) model (see Task 3). This scope <br />assumes that the survey subconsultant will be obtaining the electronic base plat and descriptions from <br />St. Joseph County. <br />Subtask 2.2- Environmental and Cultural Resources Investigation <br />STANTEC will conduct an initial assessment of potential environmental and cultural resources within the <br />limits of the project site using available reference data (e.g., wetland inventory mapping, endangered <br />species database, cultural and historical resources databases, etc.) and observations from an initial site <br />visit. The assessment will consider potential wetland areas, potential habitat for endangered species, <br />and potential sites of cultural or historical significance. <br />If the assessment determines that wetland areas are present within the limits of the project site, <br />STANTEC will delineate the limits of the wetlands. The delineation will include identification of the limits <br />for forested wetlands, riverine wetlands, and bank limits. The delineation will be coordinated with site <br />survey activities so that the wetland limits can be documented as necessary to support the development <br />of a jurisdictional determination to be submitted to U.S. Army Corps of Engineers (USACE).
