regulatory traffic control devices and flashing beacon design to determine any associated right-of-way or easement needs. STV will also identify and resolve any potential underground or aerial utility conflicts. STV will coordinate with the municipality and investigate converting Lowell Avenue to a one-way street to enable the sidewalk to be built completely within the existing cartway. 4. DRAINAGE / H&H / SWM a. Prepare Preliminary Drainage Design (3085) There are limited drainage structures within the project limits. The existing inlets conditions will be evaluated. Bicycle safe grates and curb pieces will be installed at all substandard inlets within the project

Gregory Avenue and Lowell Avenue Safe Routes to School Preliminary Engineering, Final Design, and Construction Engineering Services Page 6 Preliminary Engineering – Scope of Work limits. No hydraulic modeling is anticipated. Drainage design and improvements are not anticipated. STV will investigate alternatives to avoid triggering the NJDEP SWM Rules by reducing cartway widths such that new sidewalk (impervious area) is offset by the removal of existing roadway pavement area. Additionally, STV will investigate using porous concrete sidewalk to minimize added impervious surface area. This proposal does not include SWM analysis. If deemed a major development, supplemental services will be required. Obtain Maps for Storm Water Management Rules Compliance STV will obtain soil survey maps from the NRCS and Land Use maps from NJDEP for the study area, and a USGS Digital Elevation Model. All maps will be geo-referenced to the state plane coordinate system to delineate the drainage areas and compute the hydrologic parameters. Prepare Drainage Area Maps STV will produce drainage area maps for the study area. STV will delineate the watershed boundaries that contribute storm-water runoff to the project site. The drainage area boundaries will be field verified, and any additional drainage features identified that may alter the hydrologic characteristic of the watershed will be added. Perform Preliminary Storm Water Management (SWM) Analysis As previously mentioned, if the project exceeds the thresholds for triggering the NJDEP SWM Rules. STV will prepare calculations to determine the required water treatment and TSS percentage removal as well as water quantity volume. STV will analyze and design the SWM for flood control in accordance with NJDEP rules. Finding suitable locations for SWM BMPs will be conducted under this task. Using the soil test pits and lab analysis, any proposed basins will be designed in accordance with the BMP Manual. b. Prepare Detailed Hydrologic and Hydraulic (H&H) Analysis (3038) H&H analysis is not anticipated for this project. There are no hours associated with this activity. 5. STRUCTURES There are no existing structures impacted with the project limits. Retaining walls will be investigated to minimize impacts to the properties adjacent to the proposed sidewalk. Three retaining walls are proposed within the project limits: • Lowell

the project limits. Retaining walls will be investigated to minimize impacts to the properties adjacent to the proposed sidewalk. Three retaining walls are proposed within the project limits: • Lowell Avenue Retaining Wall, Lawrence Avenue to Helen Avenue • Lowell Avenue Retaining Wall, North of Helen Avenue • Gregory Avenue Retaining Wall a. Prepare Structural Design Recommendation Summary (3100) STV will prepare a structural design recommendation summary that documents the existing conditions, design parameters and criteria, structure alternatives development, structural selection process, recommended structure and aesthetic treatments, MPT and staging, and other essential criteria required for the proper selection of the recommended structural elements.

Gregory Avenue and Lowell Avenue Safe Routes to School Preliminary Engineering, Final Design, and Construction Engineering Services Page 7 Preliminary Engineering – Scope of Work Based on the conceptual design per the grant application, the West Orange improvements include three retaining walls and one stormwater management best management practice (BMP) site: • Stormwater Lowell Avenue Retaining Wall, Lawrence Avenue to Helen Avenue • Lowell Avenue Retaining Wall, North of Helen Avenue • Gregory Avenue Retaining Wall • Stormwater Management BMP To facilitate the new sidewalk, the Lowell Avenue retaining walls between Lawrence Ave to Helen Ave and north of Helen Avenue require fill to be placed toward private residences. As a result, borings are expected to be required to assess wall stability, potential settlement, and the potential imposed lateral pressures on the adjacent structures. Lightweight fill may be considered to mitigate potential settlement and potential risk to adjacent structures. The retaining wall at Gregory Avenue appears to be less than three (3) feet for the entire length of the wall. As a result, STV does not anticipated the need for borings along the full length of the wall as the final wall is assumed to be a landscaping wall where a regraded slope at 2H:1V or flatter is not possible. a. Develop Subsurface Exploration Program (3096) STV will review available existing geotechnical and geologic information and prepare recommendations for the subsurface investigation program based on the finalized limits and cross sections of the retaining walls and BMP. STV will prepare and submit a Subsurface Exploration Plan to the NJDOT Geotechnical and Engineering Geology SMEs for review and approval during the PE phase. STV assumes that a Preliminary Geotechnical Engineering Report will not be required. b. Review & Approve Subsurface Exploration Plan (3098) STV will address review comments and update the subsurface exploration program and bid documents. 7. RIGHT OF WAY (ROW) AND EASEMENTS Although ROW acquisition is not anticipated, it is estimated that there will be numerous temporary construction easements, as well as some permanent easements, required to execute the proposed improvements. It is not anticipated that there will be any right-of-way acquisitions. However, a full comprehensive evaluation will be performed as part of the

ements, required to execute the proposed improvements. It is not anticipated that there will be any right-of-way acquisitions. However, a full comprehensive evaluation will be performed as part of the preliminary survey and engineering related design services previously noted, to reveal all possibilities of impact. Consideration will be given to minimize impacts to the greatest extent possible as part of the preliminary engineering design, including but not limited to the feasibility of reducing the widths of the cartway or driving lanes, originally proposed sidewalks, the realignment of the existing curb-lines and various other means. a.

It is assumed there will be eight (8) impacted properties. c. Prepare & Submit ROW Plans and Documents (3122) If necessary, STV will prepare the GPPMs, parcel descriptions, and Individual Parcel Maps (IPM) for each property. The Township will be responsible for acquiring the easements if agreements with the property owners are unattainable. STV will coordinate with the Township and provide details and information to a real estate brokerage firm. Right of Way/Easement Documents: • General Property Parcel Maps (4 Sheets) • Individual Property Maps (8 Sheets) • Easement Metes and Bounds descriptions and exhibit map (5 Sheets) • Temporary Easement Metes and Bounds descriptions and exhibit map (10 Sheets) d. Prepare Initial ROW/Easement Estimate (3125) STV will develop a ROW/Easement Cost estimate. 8. ACCESS There are eight driveways within the project limits which are anticipated to be affected by the proposed improvements. The access points will be evaluated for ADA compliance with the current ADA Standards for Accessible Design, Standards for Public Accommodations and Commercial Facilities (Title III), current Public Rights-of-Way Access Advisory Committee guideline (PROWAG) and the NJDOT State Highway Access Management Code as a guide for this evaluation. Driveway adjustments and modifications are anticipated. a. Prepare & Submit Project Access Plan and Access Impact Summary (3105) STV will review and analyze the existing driveways within the project limits and verify the owners of record and existing topographic features for each impacted property. We will verify the types of access alterations identified for each property. We will confirm the use and operation of the property via field observations. STV will identify each driveway within the project area and any proposed alterations of each property’s access. b. Administer Access Alterations (3048) STV, RC and the Township will discuss any proposed/desired access alterations with the impacted property owners. Proposed improvements will be based on the desire to better control access and ADA compliance within the project limits to make for a safer environment for all users. If required, STV will prepare

If required, STV will prepare a notification letter along with a proposed plan and send, via certified mail, to the appropriate property owners. STV will document the minutes of the meeting. 9. UTILITIES a. Coordination with Utility Companies STV will determine which utility companies are serving the proposed project area through research and a field survey. Utilizing the readily available NJDOT Utility Contacts List and points of contact made available to the RC and team, STV will identify the utility owner contacts. Under this task, the coordination with any potentially impacted company will be conducted. STV will seek to avoid all utility impacts with the proposed improvements. This task will be initiated at the outset of preliminary engineering. All costs associated with obtaining this PE Utility Engineering cost estimate is included as part of this overall

Gregory Avenue and Lowell Avenue Safe Routes to School Preliminary Engineering, Final Design, and Construction Engineering Services Page 9 Preliminary Engineering – Scope of Work proposal. b. Prepare Utility Base Plans (3035) STV will prepare the utility base plans from field survey data to show existing surface utility facilities. These plans are the base plans for the development of the Utility Relocation Plan. c. Establish Utility Engineering Funding (3040) STV will coordinate with the utility providers to discuss the proposed improvements which could impact their facilities and request a cost estimate from the utility companies for their engineering services. STV will provide the latest utility cost estimate to the RC and team. If no preliminary engineering estimate is received, an anticipated utility design estimate is projected by STV for the corresponding utility company. d. Send Utility Verification Request Letter (3045) STV will prepare and send out this letter to all utility companies for final verification to confirm the existence of their facilities and their locations. Included with the letter will be the utility base plan. The utility providers will mark up the plans to verify their facilities (if any) and add type, size, depth and any operational restrictions to the base plan and return one (1) set to STV. Copies of the letters and plans will be forwarded to the RC and team. e. Prepare Utility Agreement (3050, 3060) STV will prepare a utility agreement and send to the utility companies for execution. Once the agreements are approved by West Orange, the agreement will be returned to the utility companies. f. Conduct Subsurface Utility Engineering (3080) (AmerCom) Upon the performance of due diligence and the development of the subsurface utility engineering (SUE) plan, SUE will be conducted by STV’s subconsultant AmerCom in order to determine the exact location of underground utilities. Depending upon the type of utility and potential design conflict, several SUE methods will be utilized. In locations where only horizontal location is needed, underground utilities may be located remotely using ground penetrating radar (GPR), metal detectors or similar devices. These methods will not provide utility depth. If depths of utilities are needed, we will retain a qualified contractor to excavate subsurface test pits. Utility mark-outs will be

s or similar devices. These methods will not provide utility depth. If depths of utilities are needed, we will retain a qualified contractor to excavate subsurface test pits. Utility mark-outs will be called out and performed as part of this task. Test pits will not be required to locate every utility and will only be used in locating utilities that have a potential conflict. Prior to conducting SUE test pits, STV will coordinate with any and all relevant utility companies regarding any previous SUE test pits that may have been performed for the conflict area and whether vertical data exists. Prior to conducting the SUE test pits, STV will seek approval of the plan from the RC and team and coordinate investigative site work in advance as necessary. Please see attached AmerCom’s scope of work and cost estimate. g. Utility Risk Assessment (3985) STV will assess the utility risks and identify potential conflicts. SUE will verify the locations of the facilities. STV will update the design plans to avoid impacts to the utilities.
