A. Identification and Mapping. Areas within the County which are characterized by one or more of the following groundwater problems shall be known as Groundwater Impacted Basins and shall be identified and mapped:
1. Low yielding wells having an overall average yield of less than 3 gallons per minute.
2. Basins with previously approved developments at a parcel size smaller than those stated in the table in paragraph A of Section 67.722 and in excess of available water resources.
3. Declining groundwater levels and measurable groundwater overdraft.
The Groundwater Impacted Basins shall be designated on a map known as the “Groundwater Limitations Map” which shall be adopted by the Board of Supervisors and kept on file with the Clerk of the Board of Supervisors. Prior to adding any area to said map or making any deletions from or revisions to said map, the Board of Supervisors shall hold a public hearing. Notice of such hearing shall be mailed at least 30 days in advance, to the owner (as shown on the latest equalized assessment roll) of any property proposed to be added to or deleted from said map. The Director of Planning and Development Services shall annually review said map and may recommend such revisions as the Director finds appropriate.
B. Regulations. Any application listed in Section 67.711 for a project within a Groundwater Impacted Basin shall be accompanied by a Groundwater Investigation. In addition, a Well Test shall be performed for each lot proposed to be created by or included within the project. The application shall not be approved unless the approving authority finds that based upon the Groundwater Investigation, groundwater resources are adequate to meet the groundwater demands both of the project and the groundwater basin if the basin were developed to the maximum density and intensity permitted by the General Plan.
