Project Area – The Village
There are four subareas within Dillon Beach: Oceana Marin, Village, Dillon Beach Resort, and Lawson’s Landing. This project focuses on the historic Village, which is the older and tightly clustered area of the community. Development began here in the 1910s, with most houses built in the 1930s and 1940s on very small lots, typically 1,725 square feet. Streets in this area are narrow and aligned in a general grid pattern. Of the 160 lots in the Village, 149 are developed. The Village has transitioned over the last decades from seasonal to year-round uses. Most of the area is zoned C-R1-BD for coastal single-family residential.
Water service to the Village is supplied by Coast Springs Water Company (owned and operated by California Water Service), which is an investor-owned utility (public water system) regulated by the California State Public Utility Commission (PUC). Coast Springs obtains its water from the following sources:
- Lower Well, also referred to as Well #4: This shallow well is their largest source of water and is in the channel alluvium of Dillon Creek Gulch, immediately south of the Village. This well yields between an average of 18,000 to 25,000 gallons per day, fluctuating according to the creek flow.
- Hilltop Wells: They maintain six vertical drill wells that service Coast Springs customers in Oceana Marin and the Village.
- Seasonally, they purchase water from a private well that is nearby Lower Well in the Dillon Creek Gulch.
The Village makes up approximately 60% of the Coast Springs system. Cal Water also provides service to 82 nearby properties in Oceana Marin and 13 residences south of the Village between Cliff Street and Bay Drive.
There are two storage tanks: One 120,000-gallon tank at their water treatment plant above Dillon Road east of the Village and a second 200,000-gallon tank further up the hill and east of Oceana Marin.
The water supply is subject to several sources of contamination, including high bacteriology levels and turbidity from surface water infiltration; high natural mineral content; and possible contamination from septic systems serving the Village. Therefore, all water is treated in a single treatment plant that uses iron manganese removal system, Pall membrane filtration micro-filtration, ultraviolet light disinfection, and chlorination. All treatment is contained in the treatment plant on the hill east of the Village.
Cal Water and the Tomales Fire Department routinely inspect the hydrants, which have been determined to have adequate pressure. The fire department is working with the Cal Water to maintain and upgrade older wharf hydrants.
