Planning & Building Application Review

For parcels served by an onsite wastewater treatment system (OWTS; septic system) and/or parcels served by an individual domestic water supply well, Environmental Health Services is required to evaluate that there is adequate and appropriate sewage disposal and/or potable water supply for the proposed planning and building project. Therefore, San Mateo County (unincorporated), as well as Town of Woodside, Town of Portola Valley and City of Half Moon Bay planning and building departments, refer projects for review by Environmental Health Services that may require a new OWTS, affect an existing OWTS, and/or include water supply other than a regulated water system that may be impacted by the proposed development/improvements (i.e. bedroom additions, construction outside of building footprint, accessory structures, decks, grading, drainage, landscape, hardscape, etc.).

For projects referred through County Planning and Building, Environmental Health Services review fees are paid through the Planning and Building Department. For projects referred through town or city planning and building departments, a separate Land Use Review Application with the applicable fee must be submitted to Environmental Health Services. Note: Application and fees must be received and processed prior to staff review of the project.
