1.0 INTRODUCTION
This document summarizes the scope of work for the preparation of Plans, Specifications, and Estimates (PS&E) for the Utah Avenue Overcrossing Project (Project) in the city of South San Francisco (City), San Mateo County.
AECOM will develop the PS&E for the Project consisting of the scope of work provided below. This scope of work assumes the City will advertise, award, and administer the construction contract. The bid documents will be developed to the California Department of Transportation’s (Caltrans’) standards and requirements.
They will incorporate City standards and specifications for City-owned facilities or facilities within City jurisdiction.
AECOM will develop the PS&E for the Project and submit to Caltrans and the City in various stages (35%, 65%, 95%, 100%, and Final) for review and input. Caltrans will provide Independent Quality Assurance.
AECOM is ultimately responsible for the technical design and preparation of the final PS&E and bid documents, including obtaining a Caltrans Encroachment Permit for construction.
TASK 1 – PROJECT MANAGEMENT, COORDINATION, AND ADMINISTRATION AECOM will provide project management services for each task for the entire duration of the Project. The duration of the project is estimated to be 24 months. The scope includes the preparation of a Project Management Plan (PMP) that includes scope, budget, team member roles, contacts, production standards, project schedule, deliverables, document control procedures, and a health and safety plan. The PMP will also include a quality management plan (QMP) that addresses quality assurance and control procedures and documentation. She will also supervise, coordinate and monitor activities and the work for conformance with all applicable standards; confirm consistency of deliverables; coordinate the work of in-house design staff and subconsultants; prepare monthly invoices and progress reports; and update the design schedule.
Task 1.1 Kick-Off, PDT, and City Coordination Meetings
AECOM will conduct a Project Kick-Off meeting (assume two meetings) with the City and Caltrans. Project scope, team organization, communication procedures, design schedule, critical activities, design data needs and project deliverables will be discussed.
Task 1.2 Project Development Team (PDT)
Meetings AECOM will conduct monthly Project Development Team (PDT) meetings (assume 24 meetings). Final meeting minutes will be prepared and distributed, incorporating any relevant comments received on the draft meeting minutes.

Task 2.2 Geotechnical Investigation and Testing
AECOM will evaluate the geotechnical conditions for the Project. The geotechnical and geologic investigation program will include the following tasks:
• Characterize the site-specific subsurface soil and groundwater conditions that can be expected at the foundation locations for the proposed bridge structures and retaining walls, and for the embankments and pavement sections.
• Characterize and provide recommendations for the mitigation of geologic hazards that might affect the proposed bridge structures and retaining walls.
• Provide geotechnical engineering recommendations to support the final design of the foundations for the Utah Avenue Overcrossing and four associated approach embankment retaining walls.
The specific scope of work for the geotechnical and geologic investigation program will include the following tasks:
• Perform site reconnaissance to finalize the exploratory boring locations and access routes. • Prepare project-specific Geotechnical Investigation Work Plan. • Obtain a subsurface drilling permit from San Mateo County Environmental Health Services Division, a State encroachment permit from Caltrans, and street encroachment permits from the City to conduct geotechnical explorations and sampling; and coordinate with the City to notify affected public in advance of fieldwork (access to private properties is assumed to be provided by others).
• Select and implement the most appropriate best management practices (BMPs) to be used at each exploratory boring location to minimize impact to the environment and the public. • Drill as many as 12 exploratory borings (depths ranging from 80 to 100 feet) at the proposed foundation locations for the bridge structures and retaining walls. • Drill as many as eight borings to maximum depths of about 8 feet to explore the subgrade of new structural pavement.
• Obtain representative soil samples and gather other site-specific subsurface data, including groundwater levels when feasible.
• Conduct geotechnical laboratory testing on representative soil samples. • Perform geotechnical engineering analyses to develop recommendations for the final design of foundations of the proposed bridge structure and retaining walls, sections for new pavement, and mitigation of geologic hazards. Specific engineering analyses will include the following:
Scope of Work
Preparation of Plans, Specifications, and Estimates
City of South San Francisco Utah Avenue Overcrossing Project January 2024
o Update seismic design parameters in accordance with Seismic Design Criteria, version 2.0, Foundation Reports for Bridges (January 2021) and Foundation Reports for Earth Retaining Systems (ERS) (January 2021), based on supplemental geotechnical and geological data. o Recommend and develop foundation type, depth, and capacity for compression, tension, and lateral resistance.
o Develop the lateral earth pressures for retaining wall design, including dynamic earth pressures due to seismic loading.
o Recommend foundations for retaining walls, including evaluation of sliding, overturning, and bearing capacity.
o Develop construction considerations for installation of foundations, such as pile driving, castin-drilled-hole installation, dewatering, footing excavations, and shoring requirements. o Evaluate slope stability of new embankment fills and mechanically stabilized earth (MSE) walls. o Evaluate embankment settlement with stage construction considerations. • Document all findings, and present recommendations in the geotechnical reports.
As the drilling progresses, borings will be sampled with the Standard Penetration Test, modified California, and/or Shelby tube samplers, at 5-foot intervals (or closer if changes in material type are observed). All sampling and logging of the soils will be in accordance with Caltrans’ Soil and Rock Logging Classification, and Presentation Manual. Traffic control pursuant to Caltrans standards will be provided during the drilling of all exploration sites. Clearance of underground utilities will be based on USA and private utility locate services where appropriate.
All soil cuttings generated during the drilling of the borings will be placed in drums or roll-off bins,sampled for possible contamination, and disposed of off site following reception of the analytical testing results and acceptance of the materials for disposal at a nearby Class 2 landfill. A photo ionizing detector (PID) will be on site during the exploration program to test the air around the bore hole and samples for possible volatile organic contamination. If analytical results indicate that the soil cuttings cannot be disposed of at a nearby Class 2 landfill, further testing and analysis may be required to dispose of the container of soil at an appropriate facility. This would be beyond the scope of work for this Project. AECOM assumes that Caltrans will provide an United States Environmental Protection Agency (EPA) ID number and sign any hazardous waste manifests for offsite soil disposal of hazardous soils in a hazardous waste landfill, if the soils are characterized as hazardous. AECOM will use a licensed hazardous waste transportersubcontractor and will oversee the pick-up of all the generated drums associated with the hazardous materials investigation.
Geotechnical laboratory tests will be completed to evaluate the index and strength properties of the recovered samples and will include moisture content/dry density, Atterberg limits, sieve analysis, hydrometer analysis, unconfined compressive strength, swell potential, consolidated undrained triaxial compression, consolidation on compressible clays, and “R” value for pavement design.

TASK 4 – PREPARE AND OBTAIN ENVIRONMENTAL PERMITS AND PERFORM
ENVIRONMENTAL REVALIDATION
Based on the project’s Final EIR/EA, the project has limited involvement with regulatory permits. Four necessary approvals were identified: 1) An FHWA approval that the project conforms with the Clean Air Act conformity requirements (completed during PA&ED), 2) Section 106 consultation is complete with respect to the National Historic Preservation Act requirements (completed during PA&ED), 3) the project has a Regional Water Quality Control Board Section 401 Water Quality Certification or meets Waste Discharge Requirements, and 4) the project is in compliance with the National Pollution Discharge Elimination System (NPDES) Construction General Permit requirements. Items 1 and 2 are complete and no new work is proposed. Items 3 and 4 are addressed below.
Task 4.1 Waste Discharge Requirements Authorization
There is only one surface water within the project limits at the crossing of Colma Creek. It is crossed by San Mateo Avenue, Produce Avenue, southbound and northbound US 101, and S. Airport Boulevard. The preliminary design did not require any work within ColmaCreek or its banks, and it was therefore designated as an Environmentally Sensitive Area (ESA) to be avoided during project construction. This designation will be included in the PS&E project specifications and contractor requirements. With no work in the creek a 401 Water Quality Certification is not needed because there is no need for a Section 404 permit.
In the absence of a Section 404 and Section 401 federal water quality permit requirement, the State RWQCB can require a Waste Discharge Requirements authorization. However, this is assumed only applicable for a discharge into state waters, which is limited within the project area to Colma Creek. To maintain the project’s compliance with these assumptions, the following scope of work is proposed:
• The ESA area at Colma Creek will be defined in the project plans and specifications as a resource that is excluded from construction work or discharges to the creek and its banks. This specification will be drafted and included in the PS&E package.
Scope of Work
Preparation of Plans, Specifications, and Estimates
City of South San Francisco Utah Avenue Overcrossing Project January 2024
• Consultant regulatory specialist will coordinate with the project design team during development of the plans through 65%.
• For minor discharges, a Notice of Intent (NOI) can be filled out. This project may not require an NOI since it presumably avoids a discharge because of avoidance of any work in Colma Creek or any other water of the State. If necessary, the NOI form will be filled out summarizing the project information and environmental findings. Standard conditions and general compliance will be assumed. Consultant does not anticipate that a detailed assessment is necessary or will be required.
Consultant assumes the permit application fees will be paid directly by the City, as the amount of fee is unknown at the time of preparing this proposal.
Task 4.2 NPDES Authorization
NPDES conditions are achieved through consistency or compliance with the Construction General Permit (CGP) requirements. The construction contractor is normally responsible for meeting these requirements, and it is assumed this responsibility will be specified as a contractor requirement. Therefore, no scope of work or deliverable is proposed for this regulatory requirement.
Task 4.3 Environmental Revalidation
A brief Environmental Revalidation will be provided. It will be limited to demonstrating that changes in the final design that differ from the preliminary design used for the Final EIR/EA are notsubstantially different, and/or do not introduce new significant impacts or new mitigation measures related to significant impacts.
Assumptions
• A 401 Water Quality Certification or Section 404 permit is assumed not required because there is no work proposed within Colma Creek, which is the only jurisdictional water within or near the project. AECOM assumes that Colma Creek and its banks can be designated as an Environmentally Sensitive Area (ESA) in the project specifications and plans, and the contractor will be excluded from work within the creek.
• It is assumed the construction contractor will be required to meet the current GGP conditions.
AECOM therefore assumes this will be the responsibility of the contractor and no work is proposed with respect to NPDES and GGP compliance.
• A summary NOI can be filled out if necessary, but is assumed the necessary information summarized from the approved environmental document and use of standard conditions and general compliance measures will be sufficient for the application. • AECOM cannot predict the application fees at this time and assumes that the City will provide the application fees directly. If Consultant issues the application fee, a change order may be necessary to cover the fee.
• AECOM assumes the Revalidation document will not be longer than 5 to 15 pages, and that the changes in the project can be briefly described with respect to no substantial changes in the project that could introduce significant impacts or changes in impacts that require new mitigation.
Scope of Work
Preparation of Plans, Specifications, and Estimates
City of South San Francisco Utah Avenue Overcrossing Project January 2024
Consultant assumes that any project changes will not require recirculation or any new CEQA/ NEPA documentation, beyond the brief Revalidation.
Deliverables
• Notice of Intent (NOI) application for the Regional Water Quality Control Board (if necessary and limited to demonstrating no impacts to the Colma Canal or any other water body). • Environmental Revalidation
TASK 5 – RIGHT-OF-WAY ENGINEERING, UTILITY AGREEMENTS AND
APPROPRIATE COORDINATION
AECOM will research public record maps and parcels affected by the project. We will obtain preliminary Title Reports (PTRs) required for affected parcels prior to starting boundary resolution activities. Record boundary information will be mathematized and compiled into a Land Net of the project area. Field surveys will be performed to recover and measure record boundary monumentation.
Associated Right of Way Services, Inc. (AR/WS) will assist in appraisals and AECOM will develop ROW appraisal maps for the parcels of Potentially Affected Properties for Caltrans review and approval. These maps will be prepared at a scale of 1 inch = 50 feet, per Caltrans Plans Preparation Manual and ROW Appraisal Mapping Standards.
Task 5.1 Survey Approach
The primary surveying tasks for this complex interchange improvement project include Ground Control Surveys, Photogrammetric Surveys (Caltrans ABC process), Mobile Terrestrial Laser Scanning (MTLS) Surveys, Survey Control Report, ROW Engineering, Supplemental Topographic Design Surveys, and Underground Utility Surveys.
Horizontal and vertical datums will be NAD83 (2011) CCSZ3 Epoch 2017.50 and NAVD88, respectively.
Caltrans standards contained in Chapters 2, 5, 6, 7, 8, and 9 of the Caltrans Survey Manual will be followed.
The photogrammetrist subconsultant will perform the mapping to Caltrans ABC process protocols and standards. The MTLS subconsultant will follow standards contained in the Caltrans MTLS Guidelines dated July 27, 2018. Positional accuracy standards for all surveys will conform, at a minimum, to the requirements, specifications, and results of a Caltrans Order 2cm Local Accuracy survey, also known as Third Order. Caltrans data collection and mapping standards will be used. Conforming to current Caltrans mapping standards, the mapping products will be provided in AutoCAD Civil3D (C3D) 2018 format.
Additionally, the native drawings will be converted to Microstation DGN format for use by the project team. A Caltrans Encroachment Permit will be obtained for work in the ROW, and all permit stipulations will be followed.
Task 5.2 Ground Control Surveys
A minimum four Project Control Monuments (PCMs) encompassing the project footprint will be established using static Global Navigation Satellite System techniques. PCMs will conform to the Scope of Work
Preparation of Plans, Specifications, and Estimates
City of South San Francisco Utah Avenue Overcrossing Project January 2024
requirements, specifications, and results of a Caltrans Order 1cm Network Accuracy survey. Static measurements to a minimum two passive monuments will be included. Static measurements from a minimum three and preferably four Continuous Global Positioning System stations will also be included in the ground control survey.
Following adjustment of the static control survey data to the project datums, additional control surveys will be performed. Using Total Station Survey System (TSSS) techniques, supplemental control points will be established throughout the project footprint. TSSS measurements will also be made to local first order vertical benchmarks.
Using conventional real time kinematic (RTK) double-baseline methods, measurements will be made to recovered ROW monuments to aid in land net development.
Using differential leveling techniques, a closed-loop level survey will be performed. This level survey will include measurements to the local first order vertical benchmarks, the minimum four PCMs, the supplemental control points, and selected ROW monuments. Additionally, level measurements will be taken to the 24 photopanels required for the photogrammetric survey and the 36 ground control points (GCPs) required for the MTLS survey, both discussed in following sections.
Twenty-eight field days for ground control surveys are included with this proposal.
Task 5.3 Photogrammetric Surveys (Caltrans ABC Process) Task 5.3.1 Photopanel Survey
During the ground control survey phase, 24 photopanels will be installed and surveyed to Caltrans Third Order RTK specifications, using RTK double-baseline and differential level techniques.
Task 5.3.2 “A”, “B”, and “C” Letter Submittals
AECOM will prepare the “A” letter submittal, the first requirement of the Caltrans ABC process. This letter details the mapping purpose, mapping units, control origin, datums and epoch, California State Plane Coordinate System Zone, intended map scale and contour interval, aerial camera calibration report, flight plan, control layout, proposed delivery schedule, contact information for the aerial and design consultants and the Caltrans Project Manager, and sheet and text orientation layouts.
As part of the “B” letter submittal, AECOM will prepare the “B1” Survey Control Report. This report is described in detail in a following section. Support for the remainder of the “B” letter submittal and the “C” letter submittal will also be provided.
Task 5.3.3 Photogrammetric Mapping
Subconsultant GeoCADD will perform the photogrammetric mapping. The aerial data acquisition will be performed shortly after photopanel installation is complete. The Caltrans no-fly dates of November 27 through January 23 will be respected. The native mapping platform will be C3D 2018 format using Caltrans mapping standards. Additionally, the native mapping will be converted to Microstation DGN format for use by the project team. A map compilation scale of 1 inch = 30 feet, showing 1-foot contours is anticipated.
Color digital orthophotos will be provided.

City of South San Francisco Utah Avenue Overcrossing Project January 2024
Task 5.4 Mobile Terrestrial Laser Scanning Surveys
Task 5.4.1 MTLS Ground Control Point Survey
Due to the location of the conforms and the high traffic density at these locations, MTLS surveys rather than conventional on-the-ground surveys will be used for worker safety and to limit traffic impact. Prior to MTLS data collection, MTLS GCPs must be installed and surveyed. As provided by R.E.Y. Engineers (REY), the mobile LiDAR subconsultant, 36 GCPs are required for this project. In addition to the conform locations, the MTLS survey will include the location of the proposed bridge footings in the center median of US 101. For installation and survey of the GCPs required for the center median MTLS survey, Bess Testlabs, Inc. (Bess) will be mobilized to close the #1 northbound and #1 southbound lanes during night closure work. AECOM will facilitate Construction Zone Enhanced Enforcement Program support from the California Highway Patrol for all night closure work. AECOM will prepare and submit lane closure requests through the online Caltrans Lane Closure System. The GCP survey will consist of two separate surveys:
1) GCP installation and first RTK observation, and 2) differential level survey and second RTK observation from a different base station location.
Task 5.4.2 MTLS Data Collection and Mapping
REY will perform a Type A MTLS field survey and prepare the mapping product in C3D and Microstation DGN formats, using Caltrans mapping standards. MTLS data acquisition will be performed shortly after GCP installation is complete. A map compilation scale of 1 inch = 30 feet, showing 1-foot contours is anticipated. Due to equipment and accuracy limitations, the MTLS mapping limits will generally be the hard surface extents but may include areas outside of those extents, such as shoulders, earthen islands at intersections, driveways, and other similar features where bare ground is visible.
Task 5.3 Survey Control Report
The raw control data will be reduced, compiled, and analyzed. A minimally constrained least squares adjustment of all raw survey measurement data will be prepared to determine the integrity of the survey measurements. Once analyzed and accepted, a fully constrained least squares adjustment will be prepared.
Following completion of the fully constrained adjustment, a Survey Control Report will be prepared. This report is a narrative detailing the purpose of the survey, datums used, controlling monumentation, postprocessing to include the minimally and fully constrained adjustments, and the results and conclusions. The report also includes final coordinates and elevations, project and control location maps, measurement metadata, and other required data. This report will be provided to District 4 personnel for review and approval, allowing the photogrammetric mapping, MTLS mapping, and supplemental topographic design survey and mapping to be performed.
Task 5.4 Right of Way Engineering
Task 5.4.1 Record Boundary Land Net
Using current Caltrans Record Maps (R-maps) and Survey Maps (S-maps), the current US 101 ROW will be calculated and placed into the record boundary land net, based on the location of the recovered ROW monuments. Title reports and associated supporting documents for each of the 15 acquisition parent parcels will be obtained, cataloged, and organized. The record boundary and plottable easements for each parent Scope of Work
Preparation of Plans, Specifications, and Estimates
City of South San Francisco Utah Avenue Overcrossing Project January 2024
parcel will be calculated and placed into the record boundary land net. Selected Records of Survey, Parcel Maps, Final Maps, and other record documents will also be calculated and included in the record boundary land net. Following completion of the record boundary land net, a resolved boundary land net will be prepared, using the recovered ROW and boundary monuments to determine each resolved boundary and easement line.
Task 5.4.2 Base Mapping
Upon completion of the resolved boundary land net, the Base Mapping deliverable will be prepared. This proposal assumes that 10 sheets will be required. The Base Mapping will show the applicable Caltrans ROW, all parent parcel boundaries, all plottable easements for each parent parcel, city ROWs, and other required data. The Base Mapping will be submitted to Caltrans District 4 personnel for review and acceptance. Title reports, supporting documents, and other applicable record documents will be provided to Caltrans District 4 with the Base Mapping deliverable.
Task 5.4.3 Appraisal Mapping
Upon acceptance of the Base Mapping, preparation of the Appraisal Mapping will begin. This proposal assumes that 10 sheets will be required. As determined by the civil engineering team, linework representing the required acquisitions will be incorporated into the base mapping model. The Appraisal Mapping will include the sub-parcel identifier for each acquisition parcel, the acquisition type, and the area of each subparcel, with each sub-parcel uniquely color-coded per parent parcel. Additional Appraisal Mapping items include but are not limited to parent parcel boundaries and easements, adjacent owner parcel boundaries and easements, city ROWs, prior Caltrans acquisitions, existing topography, existing Caltrans ROW, proposed Caltrans ROW, and proposed design lines. Closure calculations for each acquisition sub-parcel, each design line, and the final proposed Caltrans ROW will be performed. The Appraisal Mapping and closure calculations will be submitted to Caltrans District 4 personnel for review and acceptance.
Task 5.4.4 Plat and Legal Packages
Upon acceptance of the Appraisal Mapping, preparation of the plat and legal packages will begin. This proposal assumes that 38 plat and legal packages will be required from 15 parent parcels, including nine fee acquisitions, three permanent easements, four aerial easements, and 22 Temporary Construction Easements (TCEs). The plat and legal packages will be submitted to Caltrans District 4 personnel for review and acceptance.
Task 5.4.5 Pre-Construction Record of Survey Map
As required by Caltrans and the California Land Surveyors’ Act, a Pre-Construction Record of Survey map will be prepared and filed with San Mateo County to memorialize the Project Control Monuments, supplemental control, photopanels, MTLS GCPs, vertical benchmarks, and recovered ROW and other monuments from this survey.
Task 5.4.6 ROW Engineering Support
Surveying services will be provided as needed in support of Project Control sheet preparation, ROW Sufficiency, and ROW Certification tasks.

Task 5.7 Supplemental Topographic Design Surveys
Supplemental topographic design surveys will be performed using TSSS or RTK methods. Thirteen field days and associated mapping for supplemental topographic design surveys are included with this proposal.
Supplemental topographic design surveys include 1) above-ground utility survey (5 field days), 2) storm drain and sanitary sewer system pipe and invert survey (3 field days), and 3) topographic surveys as directed by the civil engineering team (5 field days). Caltrans mapping standards for conventional surveying will be used. CAD-model only deliverables will be provided in both C3D and Microstation DGN format.
Task 5.8 Underground Utility Surveys
Task 5.8.1 Quality Level A (QL-A)
Pothole locations will be determined by the AECOM team. A QL-A pothole survey will be performed at these locations using primarily vacuum pothole techniques. A maximum of 45 vacuum potholes are anticipated for this project. Pothole locations and elevations will be surveyed by AECOM and incorporated into the project mapping. A pothole tracking spreadsheet will also be prepared. Two field days and associated mapping for QL-A surveys are included with this proposal.

Assumptions
• Services will be conducted in conformance with the Caltrans ROW Manual. • Up to 20 project management hours are assumed for coordination on the newly implemented Caltrans Real-Time Compliance Monitoring (RTCM). Because RTCM is newly implemented, the extent of hours required for this coordination is unknown at this time. • The project may include two full acquisitions and partial acquisitions from 14 parcels with 12 to 13 property owners.
• It is assumed that a full acquisition may be required for Nos. 5 and 9. Each of these acquisitions will leave remainder parcels that may be considered remnants that are uneconomic in the market or to the owner. The appraisals are thus assumed to require a primary and alternate valuation; a full acquisition analysis, and a partial acquisition analysis that considers damages to the remainder/remnant parcel.
• Business relocation services will be required for up to three businesses, including an IHOP Restaurant (No. 5) and Bay Badminton Center and SF Elite (No. 9). • Up to two parcels (Nos. 6 and 8) with personal property-only relocations are assumed. No. 6 will likely require personal property relocation due to the removal of the hotel reception area and the meeting and conference center buildings on the Travel Lodge property. No. 8 may require personal property relocation due to the extension of Utah Avenue. It is assumed that No. 7 will not require personal property relocation for temporary storage or relocation of personal property from kiosks, and that kiosks will remain operable and will not be removed during project construction. • For No. 6, it is assumed that no long-term residents will be displaced and no impacts to rental of hotel units if the lobby/reception/conference center is impacted. Relocation for this parcel is limited to moving and reconnecting personal property.
Scope of Work
Preparation of Plans, Specifications, and Estimates
City of South San Francisco Utah Avenue Overcrossing Project January 2024
• It is assumed that up to four fixtures and equipment (F&E) appraisals will be required on Nos. 5 (IHOP Restaurant), 6 (Travel Lodge), and 9 (Bay Badminton Center and SF Elite). F&E appraisals are assumed to be provided by a subcontractor. It is assumed that no F&E appraisal will be needed for kiosks on No. 7 (Park ‘N Fly).
• It is assumed that the project impacts will not result in a full acquisition and business relocation for No. 6. If the project acquisitions and design impacts result in a full acquisition and business relocation, the budget will require additional funds.
• The AR/WS appraiser will analyze damages during the course of the appraisal assignments for each parcel. Damages are anticipated for No. 4 due to two proposed permanent easements that may result in an uneconomic remnant between the easements. Damages are anticipated for No. 6 due to the removal of the hotel reception area, the pool facility, and the meeting and conference center buildings. Damages are also anticipated because portions of these facilities may potentially need to be reconstructed as a “cost to cure” damages, and because reconstruction of an entrance is anticipated, which may result in a portion of the remainder parcel becoming an uneconomic remnant. Because No. 5 and No. 9 are likely to require a primary and alternate appraisal, damages are anticipated for each of these parcels in the Alternate Valuation, which is anticipated to be a partial acquisition analysis with uneconomic remnants. Damages are anticipated for No. 11 due to loss of site utility caused by the extension of Utah Avenue, which may include an uneconomic remnant at the southwestern corner of the parcel. It is assumed that there will be no damages to No. 14 and no loss of parking.
• Except as previously noted, no damages are assumed to remainder parcels, including temporary damages caused by loss of access or parking impacts. It is assumed that no buildings or other significant structures will be acquired or impacted, other than as previously assumed. The initial appraisal budget assumes that there are no damages to the other subject remainder parcels due to the proposed acquisitions and/or the construction of the project. If during the damages/benefits analysis conducted as part of the appraisal process for other parcels, damages become apparent to the appraiser that result in a change to the anticipated level of effort, additional budget may be requested.
• It is assumed that the parcels are not contaminated and that appraisals will not require analysis of potential remediation costs provided by others.
• Appraisal services do not include business or goodwill analyses or conclusions. Any loss of goodwill valuations should be performed by others under direct contract with the City or the City’s legal counsel.
• Budget assumes a 2- to 4-month negotiating timeframe for acquisition, and approximately three to four property owner contacts/meetings or attempted contacts. If extended negotiations and/or condemnation support services are needed, additional budget may be requested. • For Nos. 4, 5, 6, 8, 9, and 11, it is assumed that tenant consents, quitclaim deeds, or similar documentation may be needed to clear lessee interests/possessory rights from as many as seven tenants. Otherwise, negotiations are assumed to be with owners only (one on Parcel No. 4, one on No. 5, one on No. 6, one on No. 8, two on No. 9, and one on No. 11).
Scope of Work
Preparation of Plans, Specifications, and Estimates
City of South San Francisco Utah Avenue Overcrossing Project January 2024
• It is assumed that a final appraisal map and signed Certificate of Sufficiency will be provided prior to initiation of appraisal services.
• The project duration from the beginning of appraisals to ROW Certification is assumed to be approximately 15 to 18 months. An extended or expedited project schedule may increase the estimated budget.
