Construction Sites and Stormwater Management
The City of Sand City Municipal Code Title 13.05 Storm Water Management and State and Federal regulation require all construction site owners and/or operators to implement Best Management Practices (BMPs) to prevent pollutants generated from construction activities from leaving the site and entering the City’s storm drain system during wet or dry weather. This effort helps to protect the local waterways and the Monterey Bay National Marine Sanctuary.

Small Construction Sites
Small construction sites resulting in land disturbance of less than 1 acre are required to develop a site specific Erosion and Sediment Control Plan (ESCP) or Storm Water Pollution Prevention Plan (SWPPP) and must implement appropriate Best Management Practices (BMP) if construction activities include:
1) Soil Disturbance of 500 square feet or 50 cubic yards; or
2) When a site is next to water or over-water exterior work.
The ESCP must accompany the building permit application for review by City staff.
Large Construction - Construction General Permit
Large construction sites resulting in land disturbance greater than 1 acre or less than 1 acre, but as part of a larger common plan of development, must seek coverage under the Construction General Permit (CGP) prior to issuance of a local City permit for construction activity. Information regarding coverage is found at the following link:
http://www.swrcb.ca.gov/water_issues/programs/stormwater/constpermits.shtml
The CGP is regulated by the State Water Resources Control Board (SWRCB). Projects subject to the CGP will require the preparation of a Storm Water Pollution Prevention Plan (SWPPP) to be submitted to the SWRCB and the City’s Engineering and Public Works Department for review prior to permit issuance. Any construction project subject to the CGP must demonstrate coverage under the CGP in order to obtain a building permit.
Construction Site Inspections
The City of Sand City contracts with 4Leaf Inc. for all building permit inspections. City of Monterey Building Department Inspectors and/or the City Engineer perform all construction site storm water inspections. The City utilizes inspection forms developed and adopted by the Monterey Regional Storm Water Management Program. Two separate inspections forms are utilized based on the size of the construction site.
A link to a construction review and inspection checklist for sites < 1 acre is provided below.
Post-Construction Stormwater Requirements
Post-Construction Storm Water Management Requirements (PCRs) for Development Projects in the Central Coast Region are now in effect as required by the Regional Water Quality Control Board Central Coast Region. For a brief program overview, see the program brochure (PDF Brochure).
New and redevelopment projects should be designed to prevent water quality impacts from occurring, not just during construction, but throughout the life of the project. In July 2013, the Central Coast Regional Water Quality Control Board adopted Order R3-2013-0032, with new, more stringent Post-Construction Requirements (PCRs). Projects that receive their first discretionary approval for design elements after March 6, 2014 — or, if no discretionary approval is required, receive their first ministerial permit after that date — are subject to the PCRs, if they create or replace 2,500 square feet or more of impervious area. Table 1-1 summarizes the PCRs.
** These thresholds, along with a project’s Watershed Management Zone (WMZ) designation, determine the specific requirements applicable for project determination.
