9,345 people (65.5% of the population) lived in owner-occupied housing units and 4,846 people (33.9%) lived in rental housing units.Los Osos is part of the San Luis Coastal Unified School District, and is served by these public schools: Total population is in excess of 14,000, making it the most populous coastal community between Point Buchon and Monterey County.This has been much less frequent since the Chorro Bridge replaced the Twin Bridges on South Bay Boulevard.Los Osos serves as the entrance to Montaña de Oro State Park.In July 1997, the County appeared before the California Coastal Commission to address an appeal of the construction permit for the project.
The original billing for the sewer of a month in 1984 and is now (2010) estimated to exceed 0 a month with the current estimated cost of construction of the facilities and collection system to be well over 0 million before tax and interest.
Los Osos' proximity to the Diablo Canyon Power Plant means that warning sirens are located throughout the town so that the residents will be warned if the power plant should suffer a meltdown or other adverse event.
The sirens are also found in other cities nearby, including Morro Bay, San Luis Obispo and Avila Beach.
On January 1, 1999, the District was established and assumed responsibility for constructing the project.
There was also a controversy about where the sewer should be built.
