The Town's geologic maps (links below) have been prepared by the Town based on the study of aerial photographs, field investigations, and other available geologic studies. These maps portray geologic conditions with considerable accuracy. Given this level of data, the Town Council found it appropriate to adopt these maps as policy, to have them serve as guidelines for administering the affairs of the Town and to modify them from time to time as better information becomes available.
It is the Town Council's intention that these maps and related land use policies be employed as guides in all Town decisions to which they are relevant and shall be adhered to unless modifications to the geologic maps or deviations are permitted.
For questions, please contact the Town's Planning Department at (650) 851-1700 ext. 211 or email Assistant Planner Carol Borck.
