Construction Activities

During construction, uncontrolled stormwater runoff can contribute excess sediments to the storm drainage system and local waterbodies. Other pollutants can also be generated at construction sites, such as paints, solvents and concrete slurry. The purpose of the Construction Activities Program is to work with the development community to ensure proper implementation of erosion and sediment control measures.

 

drain-inlet-protectionCity activities under the Construction Activities Program include:
  • Outlining the development application process, submittal requirements and activities required during construction
  • Reviewing all land development applications
  • Holding workshops for City staff and developers
  • Requiring and reviewing Grading Plans and Erosion and Sediment Control Plans
  • Conducting inspections of all active construction sites
In addition to complying with the City’s requirements, construction projects disturbing one acre or more need to obtain coverage under the State Water Resources Control Board's General Construction Stormwater Permit. Failure to get a general permit could result in notices of violation and significant fines. The general construction permit requires preparation of a stormwater pollution prevention plan (SWPPP). The general construction permit also requires construction sites to conduct regular inspections of erosion and sediment controls measures before, after and during storm events.

New Development and Redevelopment

constructionRunoff from developed and redeveloped areas can significantly affect receiving waterbodies. As runoff flows over areas altered by development, it picks up pollutants such as sediment, oil and grease, pesticides, heavy metals, and nutrients (e.g., nitrogen and phosphorus). Additionally, development can increase impervious surfaces (e.g., parking lots, driveways, and rooftops) which prevent rainfall from being absorbed into the ground. Instead, stormwater is collected and routed to the storm drain system where large volumes of runoff quickly flow to nearby waterbodies.

City activities that work to reduce the impacts associated with new development/redevelopment include:

  • Establishing standards that require the implementation of post-construction measures to lessen the long-term impacts of stormwater discharges from new development and redevelopment. The standards apply to the following categories of development projects:
    • Significant Redevelopment
    • Single-Family Hillside Residences
    • 5,000 Square Foot Commercial Developments
    • Automotive Repair Shops
    • Retail Gasoline Outlets
    • Restaurants
    • Home Subdivisions with 10 or more housing units
    • Parking lots 5,000 square feet or more or with 25 or more parking spaces and potentially exposed to storm water runoff
  • Reviewing site plans for consistency with new development standards
  • An inspection program to ensure post-construction measures are implemented and maintained
