Our scope of services is based on the TA-2023 Application completed by the Township, input received at our online teams scoping meeting on February 12, 2024, an Essex County Washington Street / Watchung Avenue traffic signal meeting on August 19, 2024, and the NJDOT standard network diagram and activity descriptions for the PE project phase. The Township is looking to complete its goal of increasing pedestrian safety, accessibility, and walkability on Washington Street. This Washington Street Corridor Improvement Project Phase 2 will tie in seamlessly to the already initiated 2020 TAP Washington Street Corridor Improvements Project. This project is looking to improve Washington Street from Liberty Street to Meade Street. The length of the project is approximately 739 linear feet or 0.14 miles. Washington Street is an Essex County roadway, and as the project will make improvements to a County road, the Township has secured the approval of the County of Essex for this project. The improvements are being made to promote walking and better accommodate pedestrian transit as an alternate travel mode. The application identifies the proposed improvements to include improved crosswalks, signage, new sidewalks and curbs, ADA-compliant curb ramps, detectable warning surfaces, flashing speed limit signs, flashing pedestrian crossing signs, enhanced lighting, street trees, bicycle racks and trash receptacles. Deficient curb ramps, concrete driveway aprons and sidewalks will be replaced to conform with

flashing pedestrian crossing signs, enhanced lighting, street trees, bicycle racks and trash receptacles. Deficient curb ramps, concrete driveway aprons and sidewalks will be replaced to conform with ADA requirements. Proposed improvements will be consistent with previously completed streetscape projects by the Township. The intersection of Washington Street and Watchung Avenue is a signalized intersection. Traffic signal and intersection improvements are excluded from this project. Traffic signal and intersection improvements are being completed under a current Essex County Local Safety Project. As a result of communications with Essex County regarding the County signal project, it was determined that the curb line along Washington Street could not be relocated, and existing curb line would remain. This is a minor change to the scope of work listed in this project’s application.

TA-2023 Washington Street Corridor Improvement Project Phase 2 Township of West Orange Page 2 of 8 The proposed project strongly aligns with the Township’s most recent Master Plan recommendation that the design and engineering of streets and roadways in West Orange give appropriate emphasis on creating quality streetscapes, access ways, visual corridors, buffers, and related physical improvements. The project will be advanced in compliance with the Federal requirements for environmental protection by following the NEPA process, requirements for historic preservation under the Section 106 process, and policies to protect publicly owned parks under Section 4(f). Federal compliance will be documented in the Categorical Exclusion Document (CED) prepared during Preliminary Engineering. Scope of Services GPI will perform the activities as described within this scope of services. It is understood that these activities will be directed by the Township of West Orange. The activities are more specifically described as follows: Project Management: Scope Development, Budget, Schedule, and Invoicing – GPI will prepare and submit to the Township a baseline schedule in an agreed upon format for approval or comment. We will update the schedule on a monthly basis for the duration of this project.

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.

TA-2023 Washington Street Corridor Improvement Project Phase 2 Township of West Orange Page 4 of 8 The location of underground utilities will be provided by utility companies on base map markups as part of activity 3055 described below. GPR, electro-magnetic surveying and test pits or any other means for locating underground utilities is not included in this PE scope. A limited Subsurface Utility Engineering (SUE) program is included in the Final Design (FD) scope and fee proposal. Please refer to MFS’s Scope of Services and Estimate which is attached for more information. Prepare Base Maps (3025): GPI will manage and coordinate with our subconsultant, MFS, who will prepare the base maps which will depict in detail the required existing topography. The base maps will also include the baseline information and existing right-of-way as determined by field evidence and deed mosaic. This data is to be provided in accordance with Article 51 Standards and Procedures. GPI to perform a QA of MFS’s work to check that survey is in accordance with project scope and needs. Please refer to MFS’s Scope of Services and Estimate which is attached for more information. Prepare Horizontal and Vertical Geometry (3030): GPI will layout and calculate the horizontal and vertical geometry of the proposed sidewalk and streetscape improvements. The proposed geometry will be tied to the project baseline with proposed work and the project footprint defined over the base mapping to produce an accurate depiction of the project impacts. The proposed improvements will be designed to be ADA compliant where ramp grades will be 8% maximum, a minimum five (5) foot square passing space will be provided at intervals no greater than 200 feet, and cross slopes will not exceed 2%. Where sidewalks and curb ramps cannot be designed to ADA standards, variations from ADA compliance will be documented with a “Technically Infeasible Form” (TIF). Driveway grades will be corrected where the walkway portion of the driveway aprons do not meet ADA requirements and exceed 2% cross slope. We will develop critical cross-sections to identify slope impacts at locations that may result in right-of-way, utility, or environmental impacts. Streetscape improvements will extend from the curb line and, to the extent feasible, will remain within the existing right-of-way. Potential complications with curb extensions

r environmental impacts. Streetscape improvements will extend from the curb line and, to the extent feasible, will remain within the existing right-of-way. Potential complications with curb extensions include: o Conflicts with existing utilities o Relocation and modifications with existing drainage structures and conveyance piping o Altering top and bottom of curb elevations and sidewalk cross slope o Altered drainage paths o Substandard turning movements for larger design vehicles GPI will develop no more than three (3) typical sections to depict the proposed streetscape improvements showing and dimensioning roadside details such as curb, landscaping areas, sidewalk, utility poles, adjacent buildings, cut and fill slopes, and right-of-way line. Prepare Utility Base Plans (3035): GPI will prepare utility base plans from the field survey data and topographic mapping to show existing surface utility facilities. Send Utility Verification Request Letter (3045): GPI will establish utility contacts and submit the verification request letter and a set of the utility base plans to each utility company to identify their existing facilities on the utility base plans. We anticipate that this letter will be sent to no more than eight (8) utility companies. Update Base Plans and Identify Conflicts (3055): GPI will coordinate with the affected utility companies and incorporate the collective utility owner comments onto the base maps. We will review the existing utilities to

TA-2023 Washington Street Corridor Improvement Project Phase 2 Township of West Orange Page 5 of 8 identify potential utility conflicts between existing utility facilities and proposed design elements such as new street light pole foundations. Prepare Preliminary Roadway Plans (3070): GPI will prepare the preliminary roadway plans at 1”=20’ scale. The plans will include the horizontal and vertical geometry of new replacement curbs, sidewalk and ADA curb ramps, driveway aprons, limit of disturbances, planting areas, signing, replacement pavement markings and streetscape improvements throughout the corridor. Roadway improvements are limited to pavement repair strips for new curb and potential drainage improvements. No other roadway improvements are anticipated. Prepare Preliminary Drainage Design (3085): GPI will delineate existing and proposed tree cover, lawn, and impervious surfaces for the purpose of identifying whether the project is a “major development” under the current NJDEP Stormwater Management Rules (SWM). It is assumed that the project will be designed to disturb less than one acre of land and will increase impervious surfacing and/or Motor Vehicle Surfacing (MVS) by less than ¼ acre. As such, it is assumed that the project will not be classified as a “major development” and will not have to comply with the NJDEP SWM rules. Where existing drainage structures conflict with proposed curb, sidewalk and/or ADA curb ramps, GPI will develop the drainage relocation design. Relocations are anticipated to be minor and will maintain the existing drainage system to the maximum extent practicable to limit SWM and permitting implications. No hydraulic analysis will be provided. We will also conduct a rainy-day survey to identify any existing ponding issues within the right-of-way or adjacent properties with a focus on identifying and correcting any low spots in the vicinity of curb ramps and crosswalks. Drainage work will be limited to minor corrections to gutter grades to avoid ponding in crosswalks. Upgrades to stormwater drainage systems is not anticipated. A cursory review of FEMA mapping reveals that a watercourse (North Branch Wigwam Brook) crosses the project area in the vicinity of the Liberty Street/Washington Street intersection. The watercourse is an open channel beyond the ROW and confined to a piped culvert within the public ROW of Washington

project area in the vicinity of the Liberty Street/Washington Street intersection. The watercourse is an open channel beyond the ROW and confined to a piped culvert within the public ROW of Washington Street and Liberty Street. There is potential for flood hazard area, riparian zones and wetland transition zones within the project area and may be within NJDEP jurisdiction. GPI will delineate the environmental constraints with available NJDEP GIS and FEMA data and provide a map for inclusion in the PE report. GPI will determine whether the proposed impacts will qualify for one or more NJDEP FHA Permits by Rule (PBR). To qualify for PBRs the project must not be a “major development” under the NJDEP SWM Rules. Assumptions: The following assumptions are related to Task 3085 1. The project is not anticipated to disturb more than one acre of land or increase impervious surface and/or Motor Vehicle Surfacing (MVS) by more than ¼ acre. As such, the project will not be classified as a “major development” and not subject to comply with the State NJAC 7:8 and municipal stormwater management rules. 2. Drainage design is limited to maintaining existing drainage patterns. Therefore, analysis of gutter spread and pipe capacity for existing conditions is excluded from this scope. 3. Hydraulic computations and a drainage design report will not be required. 4. Upgrades to existing drainage structures will consist of relocation for sidewalk and curb extension, replacing existing casting(s) with bicycle safe grates and meeting current NJDOT standards. 5. Permitting and regulatory compliance assessments will be based on the current NJDEP SWM Rules NJAC 7:8 (3/3/2020 adoption, 7/17/2023 operative date), NJDEP Flood Hazard Area Control Act and NJDEP
