LAND DEVELOPMENT REQUIREMENTS
Under San Diego Regional Water Quality Control Board Order 2001-01, Municipal Storm Water Permit, all San Diego County jurisdictions are mandated to require the implementation of site design, source control and treatment control Best Management Practices (BMPs) for particular development projects. Prior to the completion of an application review, the above referenced projects must submit a Storm Water Management Plan for approval by the Land Development Department and implementation at the development site. Copies of the Vista Stormwater Standards Manual are available at the Land Development and Building Department counters and as Section G of the Stormwater Standards Manual.
STANDARD URBAN STORM WATER MITIGATION PLAN (SUSMP)
As required by Order 2000-01, the City of Vista has developed a SUSMP program designed to reduce or eliminate urban runoff pollution for all new development or significant redevelopment “priority project” sites subject to discretionary approval.
“Priority Projects” include:
- Residential development of 100 units or more.
- Residential development of 10 to 99 units.
- Commercial development (as defined per City Zoning Code) greater than 100,000 square feet.
- Automotive repair shops.
- Restaurants.
- Hillside development (as defined by zoning code) greater than 5,000 square feet.
- Projects located 200 feet within or directly adjacent to, or discharging directly to a creek or other watercourse, which either creates 2,500 square feet of impervious surface on a proposed project site or increases the area of imperviousness of a proposed project site to 10 percent or more of its naturally occurring condition.
- Parking Lots greater than 5,000 square feet or with greater than 15 parking spaces and potentially exposed to urban runoff.
- Streets, roads, highways, and freeways which would create a new paved surface that is 5,000 square feet or greater.
Limited Exclusion: Trenching and resurfacing work associated with utility projects are not considered priority projects. Parking lots, buildings and other structures associated with utility projects are subject to SUSMP requirements if one or more of the criteria for the above categories are met.
