Alpine Road Trail Improvements Project

San Mateo County (County) proposes to implement the Alpine Road Trail Improvements Project (proposed project) within unincorporated San Mateo County, California. The proposed project includes rehabilitation of an approximately 1.84-mile segment of the Lower Alpine Road Trail and bank stabilization at three sites along the adjacent Los Trancos Creek. Activities are proposed to occur between the limits of the Town of Portola Valley and the City of Menlo Park.

Below are links to the Initial Study/Mitigated Negative Declaration (IS/MND) that analyzes the potential environmental impacts of the trail rehabilitation work and bank stabilization work as well as the Bank Treatment Alternatives Feasibility Study.
