Urban stormwater management in the City of Santa Cruz
Contents
Summary
Information Still Needed The 1972 Clean Water Act requires areas to regulate urban runoff and other "non-point source" discharges via the National Pollutant Discharge Elimination System (NPDES) permit program. In response to the Phase II NPDES General Permit for Discharges of Storm Water from Small Municipal Separate Storm Sewer Systems (General Permit), The City of Santa Cruz has created a comprehensive Storm Water Management Program (SWMP) to manage and reduce urban runoff pollutants [1].
Regulatory Background
Legislation has been developed by multiple regulatory agencies to reduce the level of pollutants and contaminants entering the Monterey Bay and bodies of water within the San Lorenzo River watershed.
Federal
The City of Santa Cruz must comply with Urban stormwater regulations applicable to central coast region and National Pollution Discharge Elimination Systems (NPDES) legislation. In addition, Endangered Species Act (ESA) regulations apply to the population of steelhead (Oncorhynchus mykiss) present in the San Lorenzo River in Santa Cruz [2]. The ESA prohibits the impairment of habitats that contain endangered or threatened species [3].
State
The City of Santa Cruz currently operates under the State of California's General Permit for Storm Water Discharges from Small Municipal Storm Sewer Systems (MS4s). The city is required to develop and implement a Storm Water Management Plan (SWMP), and submit annual reports to the Central Coast Water Quality Control Board that summarize the city's SWMP implementation measures [4]. See Urban stormwater regulations applicable to central coast region and Central Coast Regional Water Quality Control Board (CCRWQCB) pages for specific information regarding stormwater management and legislation for this part of the state.

Timeline
- 1972 Federal Clean Water Act is the basic regulatory structure for determining allowable levels and discharges of pollutants from point sources to waters of the United States. Section 402 designates the EPA as the agency responsible for implementation of the NPDES program. Discharges are considered illegal without obtaining a NPEDS permit.

San Lorenzo Watershed
The San Lorenzo River flows from the summit elevations of the local Santa Cruz Mountains, through the City of Santa Cruz and the Coastal Zone, and out into the Monterey Bay National Marine Sanctuary and the Pacific Ocean. The entire city lies within the river’s watershed and receives runoff from areas outside of its jurisdiction. Additional agencies responsible for water quality within the watershed including in and outside of the City boundaries include: County of Santa Cruz, California Department of Parks, California Department of Fish and Game, California Coastal Commission, California Regional Water Quality Control Board, California Environmental Protection Agency, National Oceanic Atmospheric Administration, and the Environmental Protection Agency.[5] Five sub-watersheds have been identified within the San Lorenzo Watershed:
- Moore Creek
- Westside
- Neary Lagoon
- San Lorenzo River
- Arana Gulch

- Commercial businesses including food and vehicle service facilities: vehicle and equipment maintenance; food processing; vehicle washing; landscaping; and chemical and waste storage.
- Residential dwellings: vehicle washing; home vehicle repair; home painting and construction projects; chemical and waste storage; pet waste; and landscaping.
- Construction and remodeling projects: grading; vegetation removal; concrete washout; vehicle and equipment fluids; landscaping; and material and waste storage.
- Municipal sewer system and private sewer laterals: exfiltration from leaking, cracked, and debilitated pipelines; and overflows from blocked pipelines.
