The City of Thousand Oaks is responsible for numerous services within the City. If you want to report a maintenance issue please call (805) 449-2499.

Water Supply, Quality & Planning

The Public Works Department distributes up to 15 million gallons of water each day to approximately 17,000 residences and businesses. Our mission is to provide high quality water that meets or exceeds the stringent water quality standards established by the U.S. Environmental Protection Agency (EPA) and the State Water Resources Control Board. For information about the City's water conservation efforts, visit the City Sustainability Division's Water page.

Landscaping & Lighting 

The Landscaping & Lighting Assessment District (LLAD)is a special assessment area within the City that funds maintenance of the City's 27,000 street trees, medians, graffiti removal, weed abatement, streetlights, and traffic signals. The City does not maintain street lights, please contact Southern California Edison to report an outage.

Storm Drains

Storm drains are designed to prevent flooding. Water that enters our storm drains is not treated before it enters into our creeks and eventually the ocean. The City is required by the Federal Clean Water Act to comply with a Stormwater National Pollutant Discharge Elimination System (NPDES) permit issued by the State. Almost anything that enters a storm drain besides water is considered pollution.

Streets & Sidewalks

The Traffic Engineering Division's street services include assessment of neighborhood traffic concerns, implementing corrective measures to enhance vehicle, bicycle and pedestrian safety, management of City-owned traffic signal equipment, conducting traffic counts and speed surveys.


Hill Canyon Treatment Plant (HCTP) serves more than 37,300 wastewater accounts and provides sewer service to approximately 90 percent of the City. HCTP treats an average of 8.5 million gallons of wastewater per day.
