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.
What is the process?
Review Operation & Maintenance Plan Instructions
Private stormwater systems may use one of two mechanisms for recording an Operation and Maintenance Plan. Most owners record an Agreement for their stormwater system. Instructions for recording each type of Operation and Maintenance Plan are provided:
Complete Forms
Private stormwater system owners submit the following forms to the Department of Planning & Building for review prior to recording an operation and maintenance plan:
- SWP-1007 Structural Control Measure Description (Exhibit B)
- SWP-1003 Stormwater System Contact Information
- SWP-3001 Private Stormwater System Agreement
- SWP-1008 Stormwater System Plans and Manuals
Applicants should reference the descriptions of system components to determine what type of structural control measures must be recorded.
County staff must review the forms before they are notarized.
Submit Draft Form For Review
Applicants will submit the draft operation and maintenance plan for staff review. Applicants should not sign or notarize documents prior to review. Approved plans will be returned to the system owner for signature and notarization.
Pay Fees
Staff will assign a condition compliance monitoring permit to the property associated with the project. This permit will be used to track the long-term operation of the system.
Return Notarized Documents
Applicants return the signed, notarized document for countersignature by County staff. Following counter signature, County staff will record the document with the Clerk Recorder.
Construct Stormwater Structural Control Measures
Construct all features per approved Stormwater Control Plan. Structures will be inspected by County inspector, and approved on completion.
Submit Forms (Annually)
The private stormwater system owner/operator annually submits the appropriate completed self-inspection forms along with a completed stormwater inspection coversheet to verify that the system is operable and maintained in good condition. The appropriate self-inspection forms (listed below) should be included as an element of the plans and manuals provided to the owner/operator.

All structural controls installed to meet Performance Requirements 2, 3, or 4 must be included in the operation and maintenance plan. The County recognizes stormwater structural control measures outlined in SWP-2003.

The operation and maintenance plan may be created by the private stormwater system owner, their agent, or the system designer. However, the owner must sign and notarize an agreement following review and approval by the County.
The Central Coast Regional Water Quality Control Board adopted Resolution R3-2013-0032, the Central Coast Post Construction Requirements, which requires long term operation and maintenance plans for stormwater control systems on private property. The resolution specifies that the responsibility for maintaining the system must be legally enforceable and must remain with the property in perpetuity.
The County supports private stormwater system owners by providing a service to document and record the appropriate information to comply with this requirement.
