Why this project is needed:

South Bay cities are required by the Regional Water Quality Control Board of Los Angeles to prevent or treat stormwater with bacteria being discharged to the Santa Monica Bay.  Therefore, the City of Torrance is improving these stormwater basins in West Torrance to provide natural treatment systems, improve infiltration and groundwater recharge, and provide habitat restoration in these open spaces.


Project Benefits:

  • Stormwater treatment through trash screens, natural systems and infiltration basins
  • Habitat restoration
  • Enhance public viewing
  • Naturalized walking trails
  • Groundwater recharge
  • Improved landscaping and aesthetics
  • Water conservation



The Santa Monica Bay Restoration Commission has selected the Amie, Henrietta, and Entradero Basins to receive $3.3 million in Prop 84 grant funding.  This funding is still pending approval by the State Water Resource Control Board.  The City is prepared to dedicate up to $1.1 million in matching funds for final design and construction of these basin improvements.
