NOTICE OF MITIGATED NEGATIVE DECLARATION Notice is hereby given that the San Mateo County Planning and Building Department has determined that the following project will not have a significant effect on the environment and has, therefore, prepared a Mitigated Negative Declaration: FILE NO.: PLN2025-00350 PROJECT DESCRIPTION: General Plan Amendment, Major Subdivision, Grading Permit, and a Protected Tree Removal permit to subdivide 1.8-net-acre parcel into 5 parcels (Lots 1-5). The proposed subdivision requires an amendment to the General Plan designated density. Therefore, the project proposes to amend the General Plan Designation from Low Density Residential (0.3-2.3 du/net acre) to Medium-Low Density Residential (2.4-6.0 du/net acre). Site improvements, including installation of utilities and creation of a new private road required for the subdivision, result in 580 cubic yards of cut and 5 cubic yards of fill, and the removal of two protected trees. The existing single-family development and accessory structures are proposed to be demolished.
