256-25 Proposal FPA - West Orange - MS4 Compliance.pdf

MS4 Mapping Section 1 | Scope of Work In the event a structure grate or manhole needs to be removed, and is in a right of way, FPA will coordinate with municipal staff to provide traffic control and or police presence. The cost associated with traffic control and police is not included as part of this proposal, and if required, can be provided separately. Upon completion of both the desktop mapping and field verification and inspection, FPA will proceed to utilize the collected photos and data to complete entry of the remaining required attributes in the project geodatabase. FPA anticipates utilizing bulk calculation of fields which are identical throughout the dataset as well as calculating fields such as cardinal direction required for conveyance assets. Map Production & Quality Control Quality assurance (QA) and quality control (QC) will include a thorough review of field-collected GPS data, as well as the evaluation of digitized and converted data in ArcGIS Pro. This process will involve validating the accuracy of the GPS data collected during field mapping, ensuring that the locations and attributes of stormwater assets (e.g., pipes, inlets, outlets, and basins) are precise and correctly mapped. QC will also focus on identifying and correcting any discrepancies, gaps, or misalignments between the newly collected GPS data and existing GIS datasets. Special attention will be given to attribute consistency, correct feature classification, and adherence to the NJDEP’s MS4 mapping requirements. Additionally, spatial integrity checks will ensure that assets are properly connected together, and the piping is oriented correctly with proper direction of flow. Any topology errors which include overlaps, misalignments, and gaps will be addressed. This process will also involve checking the digitization and conversion of legacy stormwater data. This will ensure that older datasets have been properly georeferenced, digitized, and integrated into the modern GIS database. QA/QC will also include a verification of schema consistency, the correct assignment of attributes, and compliance with the required metadata standards. Throughout the QA/QC process, feedback will be regularly provided to the field team and digitizers to improve accuracy and minimize the need for rework. As part of the final inventory deliverables, PDF maps in Arch D size (24 x 36 inches) will be

regularly provided to the field team and digitizers to improve accuracy and minimize the need for rework. As part of the final inventory deliverables, PDF maps in Arch D size (24 x 36 inches) will be generated of the complete stormwater inventory at a scale of 1 inch = 100 feet or larger. These maps will include inlets and outfalls, the associated conveyance network, and additional key infrastructure components described above. The outfalls and other stormwater features will be labeled alpha numerically with Initial draft maps provided to the Township for review, and feedback will be incorporated into revised versions. After addressing comments and making the necessary revisions, final versions of the PDF maps will be submitted. The maps will be designed for both digital review and large-format printing, ensuring clear, precise representations of the stormwater assets. The map will be based upon the NJOGIS MOD-IV tax parcel layer and will feature streams and waterbodies, roads, The maps will include at a minimum: labeled roadways, tax parcels, streams, waterbodies, and NJDEP mapped wetlands areas. All storm water assets will be shown symbolized and labeled to differentiate between asset type and/or current condition. TASK 2: ESTABLISHMENT OF A TOWNSHIP GIS SYSTEM FPA will conduct a comprehensive licensing audit in collaboration with Township staff to inventory existing Esri products, user accounts, and subscription tiers, if available. In the event the Township has an established GIS system, FPA will utilize the existing resources to configure an interactive Stormwater inventory map. If no existing GIS resources are established for the Township, FPA will coordinate with ESRI to acquire the appropriate ArcGIS Online (AGOL) subscription, ensuring that the organization has sufficient capacity for the MS4 Inventory and any future GIS workloads. It should be noted that in the event licensing is required, fees associated with software acquisition are to be paid directly to ESRI. It is estimated that total licensing costs would be in the range of $1,500-$2,500 per year and were included in the cost for this project for budgetary purposes.

MS4 Mapping Section 1 | Scope of Work Once the AGOL organization is provisioned, FPA will immediately begin setup: configuring organizational security, creating users with corresponding roles and groups, and deploying basemaps and layers for the stormwater inventory. Throughout the initial deployment, FPA will provide training for Township staff in the use of the newly configured GIS web mapping application. The AGOL organization established for the MS4 inventory is a single, scalable platform that can be leveraged across the Township for a wide array of future GIS initiatives—such as sanitary sewer mapping, pavement asset management, vegetation inventories, and emergency response planning. TASK 3: WATERSHED IMPROVEMENT PLAN Phase I – Watershed Inventory Report The Watershed Inventory Report constitutes the foundational element of the Watershed Improvement Plan, setting the data baseline for all subsequent analyses. Its primary objective is to compile a comprehensive, municipality‑wide inventory of all stormwater related assets and conditions that influence water quality and flooding risk within and adjacent to the town. By establishing this inventory, we ensure that planning steps are grounded in an accurate, up‑to‑date understanding of the stormwater infrastructure, regulatory compliance status, and environmental sensitivities. The inventory report will also serve as a reference for future reviews, enabling a benchmark status of the TMDL and impairment levels of the municipality. The inventory will rely on multiple data sources to achieve completeness. Existing data will provide the base for outfall mapping, which was mandated in the original permitting requirements for Tier A municipalities. We will supplement this with the NJDEP GIS database (https://gisdata-njdep.opendata.arcgis.com/ ) for publicly available layers such as impervious area, land use, and overburdened community boundaries. Additional field verification will be carried out to confirm the location of private stormwater outfalls, basins, and infrastructure not currently recorded in the GIS. We will conduct GIS‑based buffer analyses to delineate drainage areas for each outfall and interconnection point. One of the key deliverables of Phase I is mapping that visually integrates all inventory items. FPA will create a multi‑layer map that overlays outfall locations, HUC-14 areas, drainage

nection point. One of the key deliverables of Phase I is mapping that visually integrates all inventory items. FPA will create a multi‑layer map that overlays outfall locations, HUC-14 areas, drainage basins, receiving water bodies, and water‑quality classification segments. GIS tools will be utilized to calculate the drainage area for each outfall and interconnection. This map will be rendered in PDF and shapefile formats to meet the Department’s submission requirements and to facilitate future stakeholder workshops and public meetings. In alignment with NJDEP’s Phase I guidance, the Watershed Inventory will include all waters within or bordering the municipality that are listed in the TMDL Look-Up Tool. For each segment, we will document the applicable TMDL pollutant parameters and impairment status. This information will be cross-referenced with the municipality’s existing stormwater outfall data to identify connections between outfalls and impaired waters. The final Phase I deliverables will consist of: 1. A written Watershed Inventory Report summarizing all collected data. 2. Electronic maps with full metadata, incorporating all required features per NJDEP guidance. These materials will be submitted to NJDEP following municipal authorization. Phase II – Watershed Assessment Report Phase II builds on the inventory from the Watershed Inventory Reports. This phase will evaluate the potential for water‑quality improvement across each sub‑watershed. The Assessment Report will prioritize projects by pollutants and by their projected percent reduction in TMDL or impaired loadings based on NJDEP’s WIP project Matrix. It will also quantify the expected benefits in terms of flooding mitigation, thereby linking water‑quality and flood‑control objectives. Township of West Orange October 30, 2025 | Page 5

MS4 Mapping Section 1 | Scope of Work The assessment will involve quantitative modeling, cost‑benefit analysis, and a comprehensive review of existing and proposed regulatory frameworks. Using the inventory data, we will identify watershed improvement projects such as green infrastructure (rain gardens, permeable pavement), potential regulation, maintenance projects and upgrades to the stormwater systems. For each potential project, we will estimate the percent loading reduction for each TMDL or impaired parameter using established load‑reduction factors (e.g., 30 % for nitrogen, 40 % for sediment). A spreadsheet model will aggregate these estimates at the sub‑watershed level, allowing us to rank projects by their overall environmental benefit and by the urgency of the associated flood risk. The assessment will also include a detailed financial analysis. For every proposed project, we will estimate capital and operating costs and identify potential funding sources. This will encompass state programs such as the New Jersey Water Bank (NJWB) and stormwater grants. A critical element of Phase II is the incorporation of community input. All feedback collected during the public information sessions will be systematically analyzed for recurring themes, concerns, and project preferences. We will present a narrative summary of this feedback alongside the technical assessment, demonstrating how public priorities have informed project selection and sequencing. Based on the technical and financial analyses, the Assessment Report will propose an implementation schedule that details recommended project priorities. The schedule will be flexible to accommodate funding, permitting constraints, and potential regulatory changes. The Phase II deliverables will consist of: 1. 2. 3. 4. A written Watershed Assessment Report with detailed project tables and cost estimates, Mapping illustrating proposed project locations, A public comment period and summary of received comments, and A preliminary implementation schedule. The report will be submitted to the NJDEP upon municipal approval. This submission will trigger a 60‑day comment period during which the public can review and provide formal input on the proposed projects. Phase III – Watershed Improvement Plan Report The Watershed Improvement Plan (WIP) is the culmination of the two preceding phases. Phase III of the

and provide formal input on the proposed projects. Phase III – Watershed Improvement Plan Report The Watershed Improvement Plan (WIP) is the culmination of the two preceding phases. Phase III of the Watershed Improvement Plan involves the development and submission of a comprehensive Watershed Improvement Plan Report that formalizes the municipality’s commitment to implementing targeted water quality and stormwater management projects. Building upon the data and assessments completed in Phases I and II, this phase will focus on selecting specific projects that address identified water quality impairments, Total Maximum Daily Load (TMDL) reduction goals, and stormwater quantity issues such as localized flooding. Each selected project will be accompanied by a detailed implementation schedule outlining key milestones, timelines, and phasing strategies. The municipality will also identify funding mechanisms for each project, which may include local capital budgets, state or federal grants, and public-private partnerships. The report will incorporate both municipal and private sector initiatives that contribute to watershed improvement objectives. The final deliverables will be a formal Watershed Improvement Plan Report submitted to NJDEP by December 31, 2027, demonstrating alignment with regulatory goals and a clear path toward measurable environmental outcomes. TASK 4: ROUTINE INLET AND OUTFALL INSPECTIONS Utilizing the Township’s newly configured Stormwater Web mapping application, FPA will create inspection forms which directly relate to inlet and outfall assets within the inventory GIS. The forms will be accessible through ESRI’s ArcGIS Field Township of West Orange October 30, 2025 | Page 6

MS4 Mapping Section 1 | Scope of Work Maps application which is available on both IOS as well as Android devices. The forms will be configured utilizing a schema derived from the NJDEP’s Outfall and Inlet inspection form templates. The forms will be designed in a manner to be userfriendly and aid in ease of data collection. As of the date of this proposal, the total number of Township owned and operated outfalls is approximately 172 structures and 3,358 inlets. These outfalls and inlets are critical in preventing flooding, maintaining water quality, and ensuring public safety within the Township's jurisdiction. As part of the NJDEP MS4 Tier A general permit requirements, at a minimum, each outfall is to be inspected every five (5) years, with a minimum of 20% of the total inspected per year, and inlets are required to be inspected annually, with catch basins inspected every 5 years. In this regard, FPA will conduct a comprehensive inspection and evaluation of all 172 outfalls, and 3,358 inlets in the first year in order to assess their current state and identify any signs of erosion, scouring, illicit connections (dry weather flow), and grate compliance. Furthermore, consideration will also be given to factors including the structural condition and general maintenance requirements such as vegetation growth or debris accumulation. Inspections will be conducted with a high accuracy GPS paired with a GIS data collection tablet utilizing the above specified ArcGIS Field Maps forms to collect photos and data fields for field workers to collect pertinent information. Once complete assessments have been conducted on the inlets and outfalls, FPA will provide recommendations if any of the inspected structures require urgent rehabilitation and/or replacement. It is worth noting that the assessment schedule remains contingent on prevailing weather patterns, it is generally required to complete inspections in favorable weather conditions and at least 72 hours after the most recent rainfall event for outfalls. Adverse weather could hinder fieldwork making it difficult for inspectors to access certain sites or properly assess the presence of illicit connections. Specific Conditions A. We will, at no additional cost, revise and resubmit documents where an error on our behalf has been identified during the approval process. However, French & Parrello Associates, P.A.,
