The primary objective of the Temescal Canyon Stormwater Best Management Practices (BMP) Project (Phase l) is to remove bacteria and other pollutants from urban runoff and keep them from reaching Will Rogers State Beach and the adjacent coastal waters.

The project, along with other approved Prop O projects, will assist in complying with the Santa Monica Bay Beaches Wet Weather Bacteria Total Maximum Daily Load (TMDL) while making our beaches and bay waters safer and healthier places.

Fast Facts::

  • Project location: In and adjacent to portions of Temescal Canyon Road and Temescal Canyon Park in Pacific Palisades, near the intersection of Pacific Coast Highway and Temescal Canyon Road. Also along a portion of PCH, south of the intersection on the east side of the road;
  • A stormwater pre-treatment facility will remove trash, debris, coarse sediment, oil, and grease prior to downstream treatment of stormwater at the Hyperion Treatment Plant;
  • All new equipment and facilities will be designed to maximize the amount of treatable dry and wet weather stormwater flows. As a result most - if not all - of the stormwater from this watershed will be kept out of the drain that flows into Santa Monica Bay at Will Rogers State Beach;
  • This first phase of work will begin in early September 2011 and be completed in fall 2013;
  • Following the first phase of work, a disinfection system will be built to allow a portion of the treated water to be locally reused for landscape irrigation;
  • Total budget: Estimated at $7.8 million (paid for by Proposition O Clean Water Bond funds)
