GPI will conduct a wetlands investigation of the area of improvements near Watson Avenue and Liberty Street. If wetlands are identified, we will delineate the wetlands and identify the potential width of the wetland transition areas for survey and mapping by our project surveyor. We will perform a preliminary investigation within 150 feet of the project area to identify the approximate location of wetlands and wetland transition areas on the subject site. Application for a Freshwater Wetlands Letter of Interpretation is excluded from this scope of work. Any potential FWW permits will be identified in the Preliminary Engineering report. Should FWW permits be required, this work will be under Final Design phase. Prepare Survey Control Report (3015): GPI’s subconsultant, MFS Consulting Engineers & Surveyors (MFS), will perform the control survey and prepare the survey control report following NJDOT standards. Information from this report will be used to recover survey control points for use in supplementary surveys for the project and for construction. GPI will coordinate survey activities with preliminary design activities and perform a QA review of the report. Please refer to MFS’s Scope of Services and Estimate which is attached for more information. Conduct Topographic Survey (3020): GPI will provide management and coordination with our subconsultant, MFS, who will conduct the topographic survey within the project limits. The topographic mapping will document the site’s existing conditions including baselines, centerlines, right-of-way lines, drainage and sanitary

nduct the topographic survey within the project limits. The topographic mapping will document the site’s existing conditions including baselines, centerlines, right-of-way lines, drainage and sanitary systems, striping, utilities, control points, and elevations. Topographic mapping will be established by field survey extending approximately 10 feet beyond ROW, including driveways and parking lots and approximately 100 feet from centerline of Washington Street onto intersecting side streets. Physical features such as signs, utilities including valves, pole #, manholes, etc. will be identified and added to the mapping. We will survey monuments as discovered in the field so adjacent property boundaries can be re-established. MFS will also prepare a ROW deed mosaic within the project area as part of the Prepare Base Map task Activity 3025. Where commercial and residential buildings are set near the right-of-way line, MFS will perform a physical survey of the concrete slabs located immediately adjacent to the buildings. The survey will tie down the horizontal and vertical location of doorway openings, the sidewalk joint(s) at the front of the buildings and the adjacent joints. GPI will request copies of County right-of-way mapping and road return documents, to be corroborated with field evidence recovered by the field surveyors to establish the existing right of way. GPI to perform a QA of MFS’s mapping products.
