Agricultural Grading

In order for agricultural grading to be exempt from a grading permit, please read the following steps to determine if the proposed grading qualifies, and how to apply.

An Agriculture Grading Form and Site Plan must be approved by the County prior to commencement of any grading activities, for verification that exemption criteria are met. 

Alternative Review Program

An applicant may elect to use the Alternative Review Program for certain agricultural grading. This process allows an applicant to obtain technical assistance, inspection, and sign-off by either the Natural Resources Conservation Service (NRCS) or the Resource Conservation District (RCD).  Please read on to learn more.

As Built Grading Permit

The process for obtaining a grading permit for grading that was done without a permit ("as-built") is the same as the process for obtaining a normal minor grading permit or major grading permit. However, as-built grading permits may incur violation fees in addition to grading permit fees. If an as-built grading permit is issued, the area subject to the as-built grading permit must be excavated and soil removed and/or replaced, as directed by a licensed engineer. This allows the engineer to evaluate the grading and ensure that it meets all county requirements. Additionally, mitigation measures may have to be performed, if the as-built grading permit is also subject to a land use permit.

If an as-built grading permit cannot be issued, the property may need to be partially or completely restored to its original state.

Major Grading Permit

A grading permit is typically needed when a project will change the topography of a property through removing and/or depositing more than 50 cubic yards of soil. Major grading typically involve 5,000 cubic yards of earthwork, or more, or earthwork proposed on terrain with slopes that are 10 percent or greater at any point.

Grading is regulated because it can cause serious problems when not done properly. Staff in the Department of Planning & Building review applications to ensure that they comply with applicable codes and ordinances before issuing a grading permit.

Post-Construction Stormwater Management

The Department of Planning & Building is required to track the long-term operation and maintenance of post-construction stormwater control measures installed within the County’s Stormwater Management Area. The Central Coast Post-Construction Requirements order the County to establish operation and maintenance plans with private stormwater system owners. The Department records plans that comply with the Requirements, which document the existence of all structures and require maintenance and operation in perpetuity by any future owners.

Stormwater Management During Construction

The Department of Planning & Building administers state and federal pollution prevention policies for stormwater runoff, verifying that appropriate stormwater permits and plans are in place prior to the commencement of construction. Department staff is available to support applicants with determining which permits and plans are required and will oversee implementation of appropriate pollution control practices during construction.

Septic Repair Permit

If your septic system needs to be repaired, you will need to submit for a permit to correct the onsite wastewater system.
