SCE-P13155.011 August 22, 2022 = Bicycle Safe Grate - Yes or No « “Drains to Waterway” casting, paint, etc. - Yes or No «Inlet Best Management Practices (BMP) — Yes or No = BMP Type * — Contributing Drainage Area - Residential, Commercial, Park/Open Space, etc. A minimum of one (1) close-up photograph of each catch basin will be captured in the field, included in the final inspection report, and connected fo that asset within the GIS. An additional photograph that shows the general location of each catch basin will also be taken. Our team will photograph any maintenance issues or unusual conditions that are observed in the field. Esri's standardized stormwater conveyance data model will be used as a starting point and then modified to incorporate NJDEP specific standards for stormwater inventorying. GIS data will utilize the New Jersey State Plane Coordinate System (NJ SPCS) derived from the North American Datum of 1983 (NAD83). The progress of our fleld work and summary of maintenance issues will be tracked within a GIS based project status dashboard in real time. The project status dashboard will include an interactive map that allows the Township to pan and zoom throughout the Township and select specific catch basin inlets to view detailed information about each catch basin and inspection results and photographs. A summary of any maintenance issues will be provided to the Township on a bi-weekly basis so that the Township can review and address when appropriate. We have assumed the following for this phase of work: * Approximately 2,000 catch basin inlets will be mapped and inspected. "Township will provide DPW staff member to assist SCE with accessing and locating catch basins. . Ouftfall Pipes Mapping Part A Our team will use a similar approach for mapping outfalls as what is proposed for Task 2 Catch Basin Inspection, Maintenance, and Mapping above. Our team has extensive experience locating, mapping, and inspecting stormwater outfalls as required by the NJDEP and MS4 permit. We have identified that the majority of time spent performing an outfall inspection is spent locating the actual outfall; not performing the inspection. As such, we propose to include an outfall inspection in this phase of work as this will
