context_page_description: Los Peñasquitos Marsh Natural Preserve and Lagoon is a coastal marsh in San Diego County, California, United States situated at the northern edge of the City of San Diego, forming the natural border with Del Mar, California. The lagoon, previously called The Soledad Lagoon, divides a colony of the endangered Pinus torreyana on a narrow coastal strip. The name "Los Peñasquitos" is Spanish for "The Little Cliffs".
context_section_description: The City of San Diego's waste water treatment and pumping stations have been improved and replaced over the years so that they do not pump treated effluent directly into the lagoon any more. Pump Station 64 is located in an industrial area at the very far upstream end of the lagoon, near the Sorrento Valley Coaster Station. Pump Station 64 has often malfunctioned and spilled millions of gallons of raw sewage directly into Los Penasquitos Lagoon, in fact between 1977 and 1986 there were 60 such spills. There were a number of improvements and fixes made, with a new $23 million facility being completed in 1988. This helped considerably in keeping the lagoon much cleaner once the new station came on-line, however there are still spills, with the most recent being on September 9, 2011 when an estimated 1.9 million US gallons (7,200 m³) of raw sewage was released due to a county-wide power outage.
  Pump Station 64 is located at 10745 Roselle Street, San Diego, California, just east of Interstate 5.
