BUSINESS OF THE COUNCIL OF THE CITY OF HALF MOON BAY
AGENDA REPORT
For meeting of: March 17, 2026
TO: Honorable Mayor and City Council
VIA: Matthew Chidester, City Manager
FROM: Dale Leda, Interim City Engineer
TITLE: APPROVAL OF A PROFESSIONAL SERVICES AGREEMENT WITH CSW STUBERSTROEH ENGINEERING GROUP FOR PRELIMINARY ENGINEERING,
ENVIRONMENTAL REVIEW AND FINAL DESIGN SERVICES FOR THE EASTSIDE PARALLEL TRAIL – SEGMENT 2 PROJECT (CIP NO. 0595)
_____________________________________________________________________________ RECOMMENDATION:
Adopt a resolution authorizing the City Manager to execute a Professional Services Agreement with CSW Stuber-Stroeh Engineering Group in an amount not to exceed $758,231 for preliminary engineering, environmental review, and final design services for the Eastside Parallel Trail – Segment 2 Project.
FISCAL IMPACT:
Funding for this phase of work is primarily supported through a $2,000,000 federal congressional earmark included in the Fiscal Year 2023 U.S. Appropriations Bill under the Department of Transportation Community Project Funding / Congressionally Directed Spending program. These funds are administered through the California Department of Transportation Division of Local Assistance.
Through Program Supplement Agreement No. F008 with Caltrans, the City is eligible for reimbursement of 88.53 percent of eligible Preliminary Engineering (PE) costs, up to $1,500,000 in federal funding. The City is responsible for providing a local match of approximately $175,000, which has been programmed in the City’s Capital Improvement Program budget.
Staff is also working with Local Assistance to transfer the remaining $500,000 from the earmark. Originally allocated for right-of-way acquisition, these funds are in the process of being obligated under the PE phase of the project so that they can be applied toward future construction.
Because the federal funding is administered through Caltrans Local Assistance, eligible project expenditures will be reimbursed to the City following submission and approval of invoices.
Completion of the preliminary engineering phase will advance the project through planning approvals, environmental clearance, and preparation of final construction drawings. 166
Construction of the project is currently estimated at approximately $3 million, and the City will pursue additional grant funding opportunities to support the construction phase.
STRATEGIC ELEMENT:
This action supports the Infrastructure and Environment and Healthy Communities and Public Safety elements of the Strategic Plan.
BACKGROUND:
The Eastside Parallel Trail is a planned multi-use trail intended to provide a continuous bicycle and pedestrian route along the east side of California State Route 1 (Highway 1) within the City.
The trail is identified in the City’s 2019 Bicycle and Pedestrian Master Plan and is intended to improve bicycle and pedestrian safety while providing an alternative north–south travel route parallel to Highway 1.
Several segments of the Eastside Parallel Trail have been constructed over time, including the Naomi Patridge Trail, which currently provides a Class I multi-use path north of the proposed project area.
The Segment 2 project represents the final northern segment of the Eastside Parallel Trail that has not yet advanced through design.
DISCUSSION:
Scope of Work
The proposed Professional Services Agreement will support completion of the Preliminary Engineering (PE) phase of the Eastside Parallel Trail – Segment 2 Project. This phase includes planning approvals, environmental clearance, technical studies, and preparation of final construction documents necessary to advance the project toward construction.
The project will construct approximately 2,100 linear feet of a 12-foot-wide Class I multi-use trail along the east side of California State Route 1 between Ruisseau Francais Avenue and Spindrift Way, connecting the existing Naomi Patridge Trail to planned trail improvements to the south.
Key project elements being considered include:
• Construction of a Class I multi-use trail
• A new approximately 200-foot pedestrian and bicycle bridge spanning Frenchmans Creek • Trail crossing improvements at three intersections with Highway 1, including Ruisseau Francais Avenue, Frenchmans Creek Road, and Spindrift Way. • Drainage improvements and repair/replacement of an existing retaining wall • Utility coordination and roadway safety improvements
Because the project is located within the right-of-way of California State Route 1, project development must comply with requirements of the California Department of Transportation and federal transportation project delivery procedures. Environmental review will be conducted 167
under both CEQA and NEPA, and the project will require preparation of regulatory permits including a City Coastal Development Permit and a Caltrans encroachment permit.
Completion of these tasks will result in final Plans, Specifications, and Estimates (PS&E) and advance the project to a construction-ready stage.
Consultant Selection Process
On December 15, 2025, the City issued a Request for Proposals seeking qualified consulting firms to provide professional engineering services for the Eastside Parallel Trail – Segment 2 project.
Several consulting firms submitted proposals by the January 23, 2026, deadline. Submittals were evaluated based on criteria including project understanding, experience with similar projects, staff qualifications, and familiarity with state and federal project delivery requirements.
Following evaluation of the written proposals, the top three ranked firms were invited to participate in interviews:
• BKF Engineers
• CSW Stuber-Stroeh Engineering Group (CSWST2)
• Mark Thomas
Interviews were conducted on February 11, 2026, and included City staff and a project representative from California Department of Transportation District 4 due to the project’s location within state highway right-of-way. Following the interviews, the panel ranked the consulting teams and selected CSWST2 as the most qualified firm to perform the work.
Recommended Consultant
Based on the proposal review and interview process, staff recommends awarding the Professional Services Agreement to CSW Stuber-Stroeh Engineering Group (CSWST2).
CSWST2 is a multidisciplinary engineering and planning firm with extensive experience delivering coastal transportation and trail projects throughout the Bay Area. The proposed project team will be led by Robert Stevens, PE, TE, who will serve as Principal in Charge and Project Manager.
CSWST2 demonstrated a strong understanding of the project’s coastal setting, environmental constraints, and Caltrans coordination requirements, and presented a design team with direct experience delivering similar trail and bridge projects along the San Mateo County coastline, including projects immediately north of Half Moon Bay.
CSWST2 will be supported by a team of specialized subconsultants, including:
• Cornerstone Structural Engineering Group – structural engineering and bridge design • LSA – environmental planning and biological resource analysis • ENGEO – geotechnical engineering and foundation investigations Cornerstone Structural Engineering Group, the proposed structural engineering subconsultant, brings extensive experience designing pedestrian bridges, retaining structures, and coastal 168
infrastructure projects for public agencies throughout California. Cornerstone has served as the structural engineer on several projects along the San Mateo County coast, including the Midcoast Multi-Modal Trail pedestrian bridges just north of Half Moon Bay, which required coordination with multiple agencies and construction within the Highway 1 corridor. This experience provides the team with direct familiarity with the structural, environmental, and regulatory considerations associated with bridge construction along the San Mateo County coastline and will help streamline design development and agency review for the project.
Based on the team’s qualifications, local project experience, and familiarity with coastal permitting and Caltrans project delivery requirements, staff determined that the CSWST2 team is well qualified to complete the work required for the Eastside Parallel Trail – Segment 2 project.
The consultant has acknowledged and accepted the standard terms of City’s Professional Services Agreement along with additional standard provisions required to meet federal project funding requirements.
Project Schedule
Upon approval of the Professional Services Agreement and issuance of a Notice to Proceed, the consultant will begin technical studies, environmental review, and engineering design for the project.
Major project development tasks will include surveying and geotechnical investigations, preparation of environmental documentation, community outreach and engagement, development of design plans at multiple milestones, and coordination with regulatory agencies for required permits.
The consultant’s preliminary project schedule anticipates completion of environmental review, design, and permitting by mid-2027, at which point the project would be ready to proceed to construction pending identification of construction funding.
Advancing the project through design and environmental clearance will position the City to pursue additional state and federal grant opportunities to fund the construction phase, which is currently estimated at approximately $3.5 million based on a 2028 construction start.

Eastside Parallel Trail – Phase 2
Project Understanding and Scope of Services
UNDERSTANDING
CSWST2 will provide engineering, environmental coordination, surveying, and design services for the Eastside Parallel Trail – Segment 2 project for the City of Half Moon Bay. The project consists of approximately 2,100 linear feet of a 12-foot-wide Class I multi-use trail along the east side of State Route 1 between Ruisseau Français Avenue and Spindrift Way. Work will include preparation of survey and base mapping, preliminary engineering, environmental documentation, and permit coordination consistent with federal requirements and the California Department of Transportation Local Assistance Procedures Manual and oversight by the Caltrans Office of Special Funded Projects (OSFP). Major elements of the scope include the following:
• Trail Improvements:Design of approximately 2,100 linear feet of a 12-foot-wide Class I multi-use trail along the east side of State Route 1 connecting the Naomi Patridge Trail to planned improvements to the south, including grading, drainage improvements, ADA compliance, and coordination with adjacent agricultural uses and coastal resource constraints. This includes evaluation and design of trail crossings at Spindrift Way and Ruisseau Français Avenue. • Pedestrian Bridge: Engineering and structural design of an approximately 200-foot-long pedestrian bridge crossing Frenchman’s Creek, including structure type evaluation, hydraulic coordination, foundation design, and preparation of Caltrans-compliant structure deliverables. • Retailing wall: The existing wooded retaining wall on the west side of State Route 1 at Ruisseau Français Avenue intersection that protects a utility pole will be replaced with a Caltrans standard wall. • Neighborhood Sidewalk and Survey Improvements: Preparation of boundary and topographic survey along approximately the first 300 feet of the Ruisseau Français Avenue right-of-way east of State Route 1 to evaluate pedestrian safety improvements, including potential sidewalks or related access improvements serving the Frenchman’s Creek subdivision. The actual improvements would be by others.
• State Route 1 Pedestrian Crossing Improvements: This includes consideration of a new pedestrian crossing across the south leg of State Route 1 at Ruisseau Français Avenue, which may require traffic signal modifications and coordination with Caltrans.
The City of Half Moon Bay has received a $2,000,000 federal earmark under the U.S. House Appropriations Bill to initiate the design of the Eastside Parallel Trail Segment 2 project. Because the project utilizes federal funding, project development and delivery will be administered through the Local Assistance process overseen by the California Department of Transportation, including compliance with the Caltrans Local Assistance Procedures Manual and applicable federal requirements. Additional funding will be required to fully fund construction of the project.
CSWST2 will coordinate with the City, Caltrans, regulatory agencies, and community stakeholders to advance the project and obtain the necessary approvals, which may include a Coastal Development Permit demonstrating consistency with the City’s Local Coastal Program, a Caltrans encroachment permit for work within State Route 1 right-of-way, and environmental permits associated with the Frenchman’s Creek crossing, including potential approvals from the U.S. Army Corps of Engineers, Regional Water Quality Control Board, and the California Department of Fish and Wildlife. The work will be performed in a manner that protects coastal resources while maintaining compatibility with the surrounding rural and agricultural character. 174

Project Understanding and Scope of Services
SCOPE OF SERVICES
Task 1. Existing Conditions Assessment
In this initial phase, our team will collect data necessary to plan for the Eastside Parallel Trail Segment 2 along State Route 1 between Rusissaeu Francais Avenue and Spindrift Way.
1.1. Project Kickoff. Our team will meet with Half Moon Bay and Caltrans staff to review the project goals as well as the existing data collected to date. At this initial meeting, we will discuss the formation of a technical working group to review project development as well as refine the community outreach strategy.
1.2. Outreach Strategy. We will prepare an outreach strategy including a schedule, a description of each engagement activity, engagement tools and methods, and a list of participants to be invited to outreach events. We propose to develop stakeholder groups to guide the project through comments and feedback at key milestones.
1.3. Data Collection. Our team will collect and review the preliminary documents to understand basic conditions along the corridor. This will include the SR-1 Repaving Project plans, Half Moon Bay Local Coastal Program and Land Use Plan, San Mateo County Sea Level Rise Assessment, and the Midcoast Multimodal Trail Project studies. Our team will complete a 24-hour mid-week count at the intersection of SR1 and Ruisseau Français Avenue to support the addition of a second crosswalk at the intersection.
1.4. Existing Conditions Mapping. Our team will complete a topographic survey along the east side SR 1 between approximate mile posts 29.94 and 30.36 as well as along approximately 300 feet of Ruisseau Français Avenue into the entrance of the subdivision. Finally, we will collect data within the intersection of SR1 and Ruisseau Français Avenue. This will include the following:
A. Property Boundary and Record Monuments: We will develop the right-of-way based upon Caltrans records, San Mateo County, and Half Moon Bay.
B. Monument Preservation: We will locate and preserve record monuments in accordance with the Business & Professions Code §8771; Streets & Highways §732 & §732.5, §1492.5, §1810.5; and Penal Code §605. We will locate these monuments and develop special provisions requiring the contractor to file a pre-construction corner record with San Mateo showing three reference control points that are tied to the monument.
C. Survey: Our team will collect topographic information along SR1, the east side shoulder, and details upstream and downstream of Fenchmans Creek as well as the locations previously noted. We will use a combination of aerial and field methods to collect data.
D. Utilities: Based on available Caltrans mapping for the SR-1 improvements, an 8-inch PG&E gas main running parallel to the trail alignment and a 2-inch PG&E gas main crossing perpendicular to the trail have been identified. Near the proposed bridge crossing, a 24-inch Half Moon Bay Sanitary District sewer line is also present. In addition to identifying surface appurtenances—such as joint utility poles located along the east side of SR-1—we will retain a contractor to pothole to verify the horizontal and vertical location of the 8-inch gas main and the 24-inch sewer line at the north and south bridge abutment. Finally, we will measure the communications conductors on the overhead utility lines.
E. Prepare Base Map: CSWST2 will develop a detailed base map integrating topography, boundary, and utility information.
1.5. Biological and Cultural Resources. LSA conducts desktop research and a field walk along the corridor to identify resources that could influence the trail’s location. We will map these features to support the trail planning process.

Project Understanding and Scope of Services
1.6. Hydrology Assessment: The bridge crossing Frenchmans Creek will need to be set above the base flood elevation. Currently, the 100-year flow is not determined, but according to FEMA records, the flow is generally contained within the banks. Our team will assess existing hydrology for the 50- and 100-year events as well as future sea level rise to confirm the base flood elevation. This analysis will consider the effect of scouring on the future bridge’s abutments and intermediate piers.
1.7. Geotechnical Investigation: ENGEO will perform a geotechnical assessment focused on the proposed prefabricated bridge location and retaining wall repair location. These tasks include:
A. Coordination and permitting for borings with San Mateo County and a Caltrans encroachment permit.
B. We will mark our boring locations and notify Underground Service Alert (USA) at least 72 hours prior to performing our subsurface exploration, and will retain a private utility locator to mark private utilities that are identified in the scan.
C. Two borings to a depth of up to 40 feet near the proposed bridge abutments and one boring to a depth of 5 to 10 feet near the retaining wall repair location. The boring near the retaining wall location will be advanced with a hand auger.
D. Soil sampling and lab testing (moisture content, density, Atterberg limits, gradation, strength, corrosion). We will measure the depth to groundwater in our borings. We assume soil cuttings can be spread at the site in landscape areas.
E. Engineering analysis to recommend foundation type, bearing capacity, embedment, anticipated static settlement, anticipated liquefaction-induced seismic settlement, soil corrosion, design groundwater, slope stability measures (as necessary), lateral earth pressures, trail section design, pavement section design, seismic design parameters, Caltrans ARS curve.
F. Preparation of a geotechnical report with recommendations for grading and earthwork, subgrade preparation, drainage, structure support, retaining wall design, and construction monitoring.

Project Understanding and Scope of Services
Objective: LSA will prepare environmental documentation pursuant to the California Environmental Quality Act (CEQA) with Half Moon Bay as the lead agency. We will prepare a Mitigated Negative Declaration (MND) supported by an Initial Study (IS) to complete the CEQA review. During this process, we will support the City in completing the NEPA analysis with Local Assistance.
3.1 Project Description. Upon definition of the preferred alternative, CSWST2 and LSA will develop a project description, in coordination with Half Moon Bay, that will describe the components of the proposed project as well as the environmental setting for the project area. The project description will provide the level of detail necessary for the technical reports and environmental documents to support thorough environmental impact analyses.
3.2 Administrative Draft Initial Study/Mitigated Negative Declaration. LSA will prepare an Initial Study in accordance with the CEQA Checklist (Appendix G of the CEQA Guidelines). The IS will include all the checklist topics and include a response to each checklist question. Environmental analysis will be based on available information and additional technical studies prepared as part of the proposed project, including the technical work conducted during the planning process. An MND will be prepared and attached to the accompanying Administrative Draft IS.
3.3 Revised Initial Study/Mitigated Negative Declaration Document. LSA will amend the Administrative Draft IS/MD based on a single set of consolidated non-contradictory comments from the City. We will submit a revised version of the document for approval. The purpose of the pre-print review will be to verify that the City of Half Moon Bay is satisfied with the new and revised text.
3.4 Public Review Draft Initial Study/Mitigated Negative Declaration Document. Presuming that a Mitigated Negative Declaration is determined to be the appropriate level of environmental review, LSA will produce a digital version of the Public Review Draft IS/MND suitable for electronic distribution. LSA will prepare the necessary public notices and will coordinate with the City to submit the Draft IS/MND to the State Clearinghouse for public review. The City will be responsible for the publication of all public notices.
3.5 Response to Comments/Final Draft Initial Study/Mitigated Negative Declaration Document. LSA will review public and agency comments received on the IS/MND during the public review period and prepare responses in a memorandum format, as necessary. LSA will also prepare a Mitigation Monitoring and Reporting Program (MMRP) using the City’s preferred format. The MMRP will list mitigation measures that are recommended in the IS/MND and provide standards and timelines for monitoring these mitigation measures. The MMRP will be submitted as an appendix to the Final IS/MND.
3.6 Public Hearing. LSA will be available throughout the IS/MND process to discuss the project and strategize the environmental documentation.
3.7 NEPA Support. We will support the City and Local Assistance in the preparation of a NEPA categorical exclusion. Based on our review of the project materials, we anticipate the following technical studies would be required by Caltrans. However, the preparation of the environmental technical reports will not begin until Caltrans has completed its review of the Preliminary Environmental Study and confirmed the scope of the technical studies. This will include the following documents, generally derived from the CEQA analysis, with LSA coordinating the effort where indicated:
A. Traffic Memorandum related to construction impacts.
B. Noise Memorandum related to construction impacts.
C. Air Quality Memorandum. LSA will sample air quality in the project area and prepare a Memorandum in relation to the selected alternative.
D. HazMat Memorandum. Geotracker shows no known contaminated areas along this segment of SR 1.
However, lead will likely be found in the soil due to its use in gasoline up to 1980. 178

Project Understanding and Scope of Services
E. Natural Environment Study (NES) and Biological Assessment (BA) to address potential impacts to special-status species and sensitive habitats.
F. Historic Property Survey Report/Archaeological Survey Report (HPSR/ASR) to address archaeological resources. After completion of this survey, and if required by stakeholders, the following additional studies may be required:
• Historic Resources Evaluation Report. Preliminary background research indicates up to 8 parcels adjacent to the proposed trail segment contain a building, structure, or object that is either documented or appears to be 45 years old (i.e., built in 1981) or older, which may require evaluation by Caltrans.
• Finding of Effect to address any identified resources in or adjacent to the project site.
3.8 Environmental Permitting. For the pedestrian bridge, this project will require permits from the Regional Water Quality Control Board, the Army Corps of Engineers, and the California Department of Fish and Wildlife. Our team will prepare applications and complete permitting, including preparation of a sensitive habitat mitigation plan.
3.9 Coastal Development Permit (CDP). The parking area is located outside of the State of California Coastal Commission’s (CCC) jurisdiction, as well as the CCC Appeals Jurisdiction; it can receive the CDP from Half Moon Bay. We will provide the following support:
A. Initial Application Review. Our team will prepare a project narrative that describes the project’s consistency with the LCP Policies and other regulations. We will meet with the assigned planner to review the application.
B. Public Notification. The City will issue public notices to owners of property within a 300-foot radius of the property. We will support staff in coordination with neighbors, which may include virtual meetings, exhibits, and narratives.
C. Permit Decision. Staff will decide if the CDP can be approved. We will coordinate with the planner to modify the application if there are issues.
D. Appeal Period. Once a decision is made, the public can appeal the decision to a higher authority, such as the Planning Commission, within 10 business days of the decision date. Should someone question the approval, we will support the District and the planning department to mitigate an appeal.
3.10 Project Study Report (PSR). CSWST2 will complete a PSR consistent with procedures established by the California Department of Transportation. Work will include project management and coordination with the Agency, review of existing conditions and available data, preparation of the project purpose and need statement, development and screening of feasible project alternatives (related to the pedestrian bridge as it is nonstandard), and preparation of conceptual engineering layouts. We will also conduct a preliminary review of environmental constraints, identify right-of-way and utility considerations, and prepare a planning-level construction cost estimate and implementation schedule. The work will culminate in the preparation of a Draft and Final PSR suitable for use as the project initiation document to support project programming and advancement into the Project Approval and Environmental Document (PA&ED) phase.
A. Caltrans Encroachment Permit. With approval of the PSR document and completion of CEQA, we will prepare final plans and encroachment permit application for review and approval by Caltrans.
