MS4 Mapping Section 1 | Scope of Work French & Parrello Associates, PA (FPA) is pleased to submit this proposal to the Township of West Orange (Township) to provide Professional Engineering and GIS Services for Stormwater System Mapping. In accordance with the New Jersey Department of Environmental Protection’s (NJDEP) New Jersey Pollutant Discharge Elimination System (NJPDES) Tier A General Permit requirements, specifically the Minimum Standards for Mapping and Scouring, and Illicit Discharge Detection Elimination and Watershed Inventory Report, municipalities are required to complete the following: Map the following MS4 infrastructure:          Outfalls Groundwater discharge points System interconnections (to/from) Storm drain inlets including catch basins Manholes Conveyance (piping and ditches) Pump stations Storm water facilities (green infrastructure, manufactured treatment devices, infiltration/detention systems) Property boundaries of maintenance yards and other ancillary operations Additionally, the NJDEP requires municipalities to develop a comprehensive Watershed Improvement Plan that is divided into three phases: an inventory, an assessment, and a final plan. The purpose of the plan is to systematically reduce pollutant loading to all receiving waters within or bordering the municipality that are subject to Total Maximum Daily Loads (TMDLs) or are listed as impaired, to mitigate storm-water flooding, and to integrate water-quality and flood-protection objectives with other regulatory frameworks (e.g., endangered-species, climate resiliency, green infrastructure). The plan must be completed in a phased, publicly-informed manner, with each phase building on the data and priorities established in the previous one. Each Phase and their underlying requirements are briefly detailed as follows: Phase I – Watershed Inventory Report (Due December 31, 2025)  Electronic mapping of all required items using the NJDEP GIS database.  Stormwater outfall data, including outfalls owned and operated by the municipality and an outfall pipe map.  Drainage area delineation for each outfall.  Receiving water bodies for each outfall, along with their water quality classification.  Mapping of stormwater interconnections from the municipality into other entities’ systems, including associated drainage areas.  Inventory of storm drain inlets owned or

ter quality classification.  Mapping of stormwater interconnections from the municipality into other entities’ systems, including associated drainage areas.  Inventory of storm drain inlets owned or operated by the municipality.  Identification of areas affected by TMDLs that lie within or border the municipality.  Identification of areas affected by water quality impairments within or bordering the municipality.  Mapping of overburdened communities and impervious surface areas.  Location and ownership details of all known stormwater outfalls, basins, and infrastructure not owned or operated by the municipality. Phase II – Watershed Assessment Report (Due on or before January 1, 2027)  Assessment of potential watershed conditions by analyzing mapped data to identify water quality impairments and flooding risks.

MS4 Mapping Section 1 | Scope of Work        Identify potential projects or actions that will address water quality impairments, TMDL reductions and stormwater quantity issues. Summarize public feedback gathered from the semi-annual information sessions. Provide an estimate of funding needs for each project, identifying potential sources (NJ Water Bank, SWU formation, grants, FEMA BRIC grants, etc.). Develop an implementation schedule for all proposed projects to meet TMDL reduction goals and improve water quality and quantity issues Post the report on the municipality’s website and initiate a 60-day public comment period for formal input. Provide a timeline for implementation of selected projects Semi-annual public information sessions (in-person or virtual) to be conducted following the completion of Phase II of the Watershed Improvement Plan. Phase III – Watershed Improvement Plan Report (Due on or before December 1, 2027)  Phase III focuses on project selection and committing specific water quality and stormwater improvement projects based on the assessments and data compiled in Phases 1 and 2.  Identify the proposed projects from phase 2 that will be implemented to address water quality impairments, TMDL’s and flooding concerns.  Summarize public comments received and document any changes made to the final plan.  Present the proposed timeline for selected water-quality improvement projects identified in Phase 2.  Provide the schedule of public information sessions to be held during the implementation phase.  Identify problems outside municipal jurisdiction (e.g., agricultural pollutant loading, non-municipal lands) and opportunities to address them.  Break down project costs by year and list funding opportunities that can be pursued. Based upon the requirements highlighted above, we offer the following scope of work detailing the work tasks included in our proposal: SCOPE OF WORK TASK 1: MS4 INFRASTRUCTURE MAPPING – COMPLETION OF MS4 STORMWATER INVENTORY It is FPA’s understanding that the Township has completed a majority of their stormwater inventory as of the date of this proposal. Upon review of the data, FPA has identified the following stormwater inventory assets and the approximate quantity of each:         Inlets: 3,358 Outfalls: 172 Groundwater Discharge Points: 91 Interconnections: 0 Retention/ Detention Basins:

llowing stormwater inventory assets and the approximate quantity of each:         Inlets: 3,358 Outfalls: 172 Groundwater Discharge Points: 91 Interconnections: 0 Retention/ Detention Basins: 0 Surface Conveyance: 0 Subsurface Conveyance: 0 Manholes: 0 Based upon this cursory review of the existing inventory data, FPA has determined that conveyance, interconnections, retention/detention basins, manholes, and any other relevant stormwater facilities still need to be identified and mapped. To complete this task, FPA will coordinate with Municipal staff to obtain existing municipal stormwater infrastructure Township of West Orange October 30, 2025 | Page 2

MS4 Mapping Section 1 | Scope of Work mapping which may include GIS data in the form of geodatabases, shapefiles, PDF files, or hardcopy maps and plans. Utilizing data sources such as the NJDEP’s Bureau of GIS and the New Jersey Office of Geographic Information System’s Open Data portal, FPA will obtain road centerlines, MOD-IV tax parcels, National Hydrography Dataset (NHD) Streams and Waterbodies, and Wetlands of New Jersey to create a basemap upon which the Stormwater infrastructure inventory will be mapped. With the latest version of the NJDEP’s MS4 ESRI geodatabase template, FPA will utilize ESRI’s Arcmap or ArcGIS Pro software to configure the Township’s stormwater database for completion of the municipality’s stormwater infrastructure inventory in NAD83 New Jersey State Plane US survey feet. The database, which reflects the NJDEP’s current stormwater mapping requirements, will contain the following feature classes for data conversion and collection:            Inlets Outfalls Conveyance, Subsurface Conveyance, Surface Interconnections Groundwater Discharge Points Manholes Stormwater Management Basin Pump Stations Stormwater Facilities Municipal Properties FPA will complete conversion of existing stormwater data as required through georeferencing of PDFs and hardcopy maps along with importing existing GIS data to the project geodatabase into the appropriate feature class as listed above. Once this initial mapping phase of the project is completed, FPA will utilize the most recent leaf-off aerial imagery provided by Nearmap US, Inc. to locate and plot any additional stormwater assets that are readily visible, which may include: inlets, outfalls, stormwater management basins, and pump stations. High Accuracy Mapping and Additional Data Collection While FPA, as a standard, makes a best effort to approximate pipe sizes and materials, elevation and invert data is typically not typically ascertained unless explicitly requested by the client since this is not a requirement of the NJDEP for stormwater inventory submittal. It is FPA’s understanding that the Township is requesting high accuracy data collection in addition to the standard mapping tasks to be completed in Task 1 of this Proposal. Due to the nature of high accuracy data collection, which requires additional loiter time at each asset for the setup of a high accuracy GNSS unit,

ng tasks to be completed in Task 1 of this Proposal. Due to the nature of high accuracy data collection, which requires additional loiter time at each asset for the setup of a high accuracy GNSS unit, the measurement of the pipe diameters, identification of materials, and the measurement of the invert, this increases the overall length of field work activities. FPA will utilize Trimble TDC 600 GIS tablets paired with Emlid Reach RS3, Emlid Reach RX , or Trimble Catalyst RTK GNSS receivers receiving real time corrections from the Alpha RTK network which covers New Jersey for the highest accuracy possible. FPA will collect the elevation of the grate or manhole rim and utilize a measuring stick or laser measuring device to measure down to each invert as well as collect pipe sizing. It should be noted, this data will be collected by GIS field staff and will not be surveyed by a PLS. The information collected is intended to be utilized in a GIS for informational purposes only. In addition to the elevation data, FPA as a standard, includes GNSS metadata data collection such as HDOP, PDOP, VDOP, Horizontal RMS, and Vertical RMS to assist in validating the accuracy of data collected. ESRI’s Field Maps software will be configured with the features and attributes listed above so as to allow users to verify existing assets and add new ones via a data entry form. As per the NJDEP’s template geodatabase schema, each distinct stormwater asset type requires several mandatory fields to be completed which will be incorporated into the Field Maps application’s form. During the inspection process, a minimum of one photo per asset will be collected. When material type and pipe size are to be recorded, FPA will attempt visually approximate pipe sizing and observe material type without removing or disturbing the grate, lid, or manhole of the structure.
