Our scope of services is based on the SRTS - 2022 Application completed by the Township, input received at our virtual Scope of Work kickoff meeting on March 13, 2023, our field meeting on May 4, 2023, June 6, 2023 meeting minutes and the NJDOT standard network diagram and activity descriptions for the PE project phase. The project’s purpose is to perform improvements to enhance safety of the various routes to schools in the Township thus enabling and encouraging more students to walk and bike to school and provide a safe walkable community for the residents. The grant application identified twenty-one school intersections, as listed below, for pedestrian safety enhancements. Many of these locations will consists of providing solar powered flashing school advance crossing signage assemblies. These assemblies would be radio-controlled and activated by a School Crossing Guard through the controller box at each intersection. Though not identified in the grant application but discussed in our meetings, solar powered rectangular rapid flashing beacon school crossing signs with push-button activation will be installed at ten (10) pedestrian crossings occurring at not stop-controlled locations. To ensure ADA compliance at the pedestrian crossings affected by the proposed signage improvements, this project will include the evaluation and, if necessary, upgrades to curb ramps at these locations. This was confirmed by NJDOT at the project field meeting. Once completed, the proposed improvements will create safer routes to the various schools throughout the Township. The project will be advanced in compliance with the Federal requirements by following the NEPA process, requirements for historic preservation under the Section 106

us schools throughout the Township. The project will be advanced in compliance with the Federal requirements 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 by NJDOT Bureau of Programmed Resources.

The topographic survey data will include, but not be limited to: 1. Driveways, roadway pavement, grass, gravel, asphalt, trees, landscaping, traffic striping and signing, curb, islands, sidewalk, property and roadway monuments, guiderail, and railroad rails and equipment. 2. Bodies of water, ditches, and pipe systems indicating direction of flow. 3. Utility poles and numbers and elevation of all aerial utility lines within the survey area. 4. Any utilities in the roadway, such as: junction boxes, highway lighting, traffic signals, gas valves, water valves, sanitary sewer manhole rim elevations, and all drainage inlet and manhole grate and rim elevations. Invert elevations, pipe sizes and pipe types will be obtained from record plans provided by the Township. Structures will not be entered and any structures with excessive debris and/or silt will be noted. GPI will not clean or attempt to remove debris or silt. 5. Surface data within the limits of the project. 6. Base mapping to be revised on an as-required basis to include utility underground information as received from the Utility Owners on the project site.

SRTS-2022 Design Assistance Program Township of West Orange November 13, 2023 Revised July 16, 2024 Page 4 of 8 Primary Tasks: 1. Establish existing ROW and no-access lines using existing plan and deed information. 2. Perform bench run, based on recovered survey control. 3. Conduct topographic survey, utility location survey and ROW location survey. 4. Provide a “traverse.dgn” file containing the survey and supplemental control points along with any traverse created for the project. 5. Develop a table summarizing points, coordinates, elevations and descriptions to be inserted into the traverse file. a. The points to be used as benchmarks for construction will be identified in the table. b. A separate file containing swing tie data will be provided as a supplement to the data provided in the Field Notes. Technical Assumptions: 1. GPI will utilize a combination of conventional survey methods, GNSS survey methods, and 3D laser scanning (LiDAR) methods to collect the survey data. It is estimated that features extracted from the LiDAR point cloud will have a tolerance of less than one-quarter inch (¼”). 2. A highway occupancy permit will not be required. 3. Lane closures will not be required. Prepare Base Maps (3025): GPI will perform a field edit of the base mapping to verify its accuracy based upon the survey data collected in Activity 3020. The mapping efforts will adhere to the NJDOT Survey Manual, BDC13T-04. The ROW and no-access lines for all adjacent parcels will be established from deeds and plotted on the base maps in accordance with NJDOT ROW procedures and guidelines. CADD processing and editing – All files will be developed using NJDOT standards with regards to level, color and symbology. These files will be used during compilation of the planimetric features to ensure consistency across the entire project. Editing of the digital files collected during compilation is performed on individual workstations. At this stage individual models are combined and edited to produce the final map. All the scanned data is run through a final CADD edit. This is done to ensure that proper line styles, line weights, levels and symbology conform to NJDOT Survey Manual and CADD Standards Manual. Digital Terrain Models (DTM) – A DTM will be created from the survey work. The DTM will be of sufficient accuracy to evaluate existing pavement grades and establish new pavement

CADD Standards Manual. Digital Terrain Models (DTM) – A DTM will be created from the survey work. The DTM will be of sufficient accuracy to evaluate existing pavement grades and establish new pavement grading. The surface DTM will be established to the extent of the project limits, including roadside surfaces, at a minimum to the ROW line. ROW will be developed and plotted from deeds for the parcels within the project limits. We will generate final contours. The quality control process will include a field check. The base map data will be reviewed for features missed during data capture and to review the final CADD files for consistency and accuracy. Potential DTM errors, such as spikes or anomalies, such as significant erosion near a parapet wall, may be resurveyed for verification before the final files are created. A quality assurance review will be performed on the final CADD files. Primary Tasks: 1. Field edit base mapping to verify field data. 2. Update base mapping on an as required basis to include utility underground information as received from the Utility Owners on the project site. 3. Plot the ROW and no-access lines from deeds, maps, and/or plans. 4. Prepare final mapping of existing topography information. 5. Perform QA review on the final base mapping. Prepare Horizontal and Vertical Geometry (3030): GPI will layout the proposed curb ramps and calculate the proposed horizontal and vertical geometry where curb ramps are deemed to be non-compliant with ADA requirements. The proposed geometry will be tied into the project baseline as developed by GPI, with proposed work and project footprint defined over the base mapping to produce an accurate depiction of the proposed impacts.

SRTS-2022 Design Assistance Program Township of West Orange November 13, 2023 Revised July 16, 2024 Page 5 of 8 This project includes evaluation of existing curb ramps at the identified pedestrian crossings. It is anticipated that no more than 61 individual curb ramps will be evaluated for ADA compliance. ADA ramps, at the proposed pedestrian signage improvements, will be laid out and preliminarily graded to determine proposed impacts. It is anticipated that the use of concrete curb headers will be necessary at various locations where ADA Ramps are to be constructed to eliminate the need for ROW impacts. Improvements to any existing curb ramps not being directly affected by the proposed school crossing sign improvements at crosswalks, are not included in this scope of work. Pursuant to MUTCD (2009), Section 7B.12, school crossing assembly signage shall not be installed on approaches controlled by a stop condition. Accordingly, school crossing signage will not be installed at the seven (7) signalized intersections, as there are no improvements proposed at these crossings. Evaluation and upgrades for ADA compliance at these locations is outside the scope of this project and excluded from this proposal. Prepare Utility Base Plans (3035): GPI will prepare utility base plans from the field survey data to show existing surface utility facilities. Send Utility Verification Request Letter (3045): GPI will establish utility contacts and submit the verification request letter and two sets 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 six (6) 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 identify potential utility conflicts between existing utility facilities and proposed design elements. In coordination with the utility companies, we will identify subsurface utility engineering (SUE) test pit locations at the potential conflict points to verify the exact location of the existing utilities. However, we anticipate after Activity 3055 it will be determined that there is a low risk of utility conflict and SUE work will not be necessary. We anticipate the project will not result in utility

. However, we anticipate after Activity 3055 it will be determined that there is a low risk of utility conflict and SUE work will not be necessary. We anticipate the project will not result in utility relocations and therefore utility agreements are not expected. Prepare Preliminary Roadway Plans (3070): GPI will prepare the preliminary construction plans at 1”=20’ scale. Preliminary Plans will depict the solar powered flashing school crossing signage assembly, radio-controlled controller boxes, reconstructed curb and sidewalks, limit of disturbances, and tree removal and trimming throughout the project. Roadway improvements are limited to pavement repair strips for replacement curbs where necessary. No other roadway improvements are anticipated. Sidewalk replacement is limited to curb ramp upgrades at the pedestrian crossings being affected by this project. Curb ramps and associated sidewalk will be ADA compliant with cross slopes not exceeding 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). We will develop critical cross-sections to identify slope impacts at locations that may result in right-of-way, utility, or environmental impacts. Improvements will extend from the curb line and, to the extent feasible, will remain within the existing right-of-way. Prepare Preliminary Drainage Design (3085): We 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 NJDEP Stormwater Management Rules. It is assumed that the project will be designed to disturb less than an acre of land and will increase impervious surfacing (including areas of flows redirected from lawn to curbed pavement) by less than ¼ acre. Gutter lines may be modified, if necessary, to correct any ponding at the curb ramps. We will review the proposed grading impact on adjacent properties and determine the need to provide for modified grading or catch basins to address ponding which may result from the construction of proposed sidewalk and curb ramps. Where existing stormwater inlets are present within the work area, we will propose the replacement of the grates and/or reconstruction of the existing inlets as necessary to accommodate the proposed curb; however, we do

mwater inlets are present within the work area, we will propose the replacement of the grates and/or reconstruction of the existing inlets as necessary to accommodate the proposed curb; however, we do not anticipate the need to perform hydrologic, hydraulic, spread or capacity calculations. Environmental constraints maps will be prepared for inclusion in the Preliminary Roadway Plans.
