BACKGROUND:
The Tunitas Creek Beach County Park (Tunitas Creek Beach) is a 58-acre County-owned and operated park located in unincorporated San Mateo County approximately eight miles south of the City of Half Moon Bay. Tunitas Creek Beach features almost one mile of sandy beach, steep coastal bluffs, and the mouth of Tunitas Creek. Purchased in 2017 by the Peninsula Open Space Trust (POST) and transferred to the County in 2020, Tunitas Creek Beach will be the first recreational beach park in the County Parks system. In 2019, the San Mateo County Parks Department (Department) along with POST and other project partners began a robust public engagement process to determine the design of new Park amenities and facilities for the property.
On August 6, 2019, this Board adopted Resolution No. 076842, which authorized an agreement with CSW|ST2 for the professional services required to design and permit the Tunitas Creek Beach Improvements Project (Project).
On December 14, 2021, this Board adopted Resolution No. 078636, which certified the October 2021 Initial Study/Mitigated Negative Declaration (IS/MND) consistent with CEQA requirements. This Board also adopted Resolution No. 078635 on December 14, 2021, authorizing the Parks Director, or the Parks Director’s designee, to submit an application to the California Department of Parks and Recreation’s Proposition 68 Per Capita Grant Program seeking $828,430 in grant funds to construct a portion of the Project.
On January 31, 2023, this Board adopted Resolution No. 079437, which authorized the Director of Public Works to proceed with finalizing the plans and specifications for the Project, proceed with advertising for bids on the Project, and report back to this Board with recommendations on awarding a contract.
DISCUSSION:
The feedback received during the public engagement process determined that people value the natural character of Tunitas Creek Beach. The Project improvements are described by location as upper-bluff, mid-bluff, and beach. Upper-bluff amenities include an improved parking area, a scenic overlook with bench seating, an accessible pedestrian pathway to the mid-bluff with rest stops and overlooks, and a loop trail leading to the beach, which begins at the south end of the parking area. Mid-bluff amenities include public restrooms, tiered amphitheater style seating and gathering space, picnic tables, interpretive displays and signage, and improved beach access via the existing service road. For added site security, a ranger residence is also proposed at the mid-bluff. The beach has minimal development, and instead offers park users opportunities for passive recreation.
Site improvements will also involve utilities improvements and traffic flow improvements into the new parking lot off Highway 1.
A portion of the Project is located within California Department of Transportation’s (Caltrans) right-of-way. The Parks Department must obtain approvals from Caltrans for the upper-bluff improvements in their right-of-way, which includes: executing an Airspace Lease Marler-Johnson Park Agreement (Agreement) and obtaining an encroachment permit for all work in the Caltrans road right-of-way. The Agreement will designate the County as the lessee of this portion of Caltrans’ right of way and will allow Parks to construct, maintain, and manage operations of the proposed parking lot for this Project. The proposed Agreement has been reviewed and approved by the Real Property Services Division, the County Attorney’s Office, the Department of Public Works, and the Parks Department. Once Caltrans has reviewed the agreement and approves, it will be forwarded for execution by the County Executive Officer, or designee.
Pacific Gas and Electric Company’s (PG&E) Rule 20B program allows agencies to coordinate with PG&E, pay for the relocation of existing overhead electrical facilities, and place them underground through a Rule 20B agreement. The Project plans and specifications include construction of the necessary underground infrastructure, which have been reviewed and approved by PG&E for construction. The Project’s Contractor will perform the necessary trenching and installation of the underground conduits and substructures. Upon completion the Contractor’s work, PG&E will place the electrical wires in the new underground system and remove the existing overhead electrical facilities and poles. The proposed Rule 20B Agreement has been reviewed and approved by the County Attorney’s Office, the Department of Public Works, and the Parks Department. Upon the approval of this Board, the Director of Parks, or designee, will execute the Rule 20B agreement with PG&E. The Parks Department recommends authorizing execution of the Rule 20B agreement with PG&E to facilitate this work.
The Parks Department has finalized the plans and specifications for the Project.
