3. Outfall Pipes Mapping Part A The Township is required to update their existing 2009 Municipal Outfall Pipe Mapping which will required to locate all municipally owned and operated outfall pipes. Outfalls are to be located for submission to NJDEP and will need to in the ESRI GIS environment on NJ State Plane coordinate system required by the NUDEP. The data collection will include: GPS data on all outfalls that can be field-located based on the 2009 Municipal Outfall Pipe Mapping Any additional outfalls found in the field which are not in the 2009 Municipal Outfall Pipe Mapping GPS data on all outfalls that can be field-located A photograph of each outfall identifying the type of outfall and its receiving surface waterbody name eocee Township to provide personnel to assist with access and location of stormwater facilities. The graphical basis for this analysis will be the base map compiled from existing asbuilt plans, and other sources to build a useful and supportive base map for the Township's outfalls mapping. The data collected for mapping will need to be in the ESRI GIS environment on NJ State Plane coordinate system required by the NJDEP. This base map will be used as a starting point for field data collection, and it is expected to be uploaded on mobile devices to record future data and supporting documentation. GPI will locate, inspect, and photograph Municipal Outfalls using GPS/GIS in compliance with the NIDEP GPS Data Collection Standards and ESRI GIS environment on NJ State Plane coordinate system required by the NJDEP. GPI will prepare a suitable GIS basemap from existing Township as-built plans and other available sources. Part B The Township will be required in the next permit cycle starting in 2023 to comply with additional mapping requirements to the Municipal Separate Stormwater Sewer System (MS4 permit) that will require the following additional data collection: e MS4 ground water discharge points (type) e MS4 interconnections (type into/from, entity) e — Storm drain inlets (type, catch basin present, label present, retrofitted) e MS4 manholes e MS4 conveyance (type, direction of flow) e MS4 pump stations e Stormwater facilities (type) e Property boundaries of maintenance yard(s) and other ancillary operations (type) Using GIS methods for this Task, GPI will identify locations and include them on the GIS basemap,

facilities (type) e Property boundaries of maintenance yard(s) and other ancillary operations (type) Using GIS methods for this Task, GPI will identify locations and include them on the GIS basemap, including their associated attributes noted in parentheses. GPI assumes the following : e MS4 groundwater discharge points will be collected from available State GIS data e MS4 interconnections locations will identified by Township staff e Township staff will assist in providing locations of municipal stormwater facilities ¢ — Property boundary information required above will be taken from available sources, such as Township Taxmaps. Boundary surveys are excluded from this proposal. GPI Scope of Services/Fee Proposal | Page 3
