Final / Parcel Map

Once you have received approval of your Tentative Map, you will need to submit a Final or Parcel Map for the review of the Public Works Department prior to approval by the County Board of Supervisors.

A Final Map is required for Major Subdivisions, and a Parcel Map is required for Minor Subdivisions.

Below are some helpful checklists and documents to assist you in preparing your first submittal to the Public Works Department for review of your Final or Parcel Map.
