Notice of Exemption for the Irish Beach Water District Well Activation & Tank Restoration Project. The overall project objective is to improve drought and water storage resiliency and preparedness for the 50-year-old rural community of Irish Beach, through its Water District, even in the face of potential reduced stream flows and decreasing annual rainfall. This will be accomplished by:
(1) Installation of a conventional 11,000-gallon “bolted steel on concrete foundation” water tank. A temporary poly tank is currently used to replace a failed original 10,000-gallon ferro-cement and redwood tank. Installation of a new bolted steel tank will be used to store the water from an existing well and serve as a buffer to match pumping capacity to system water use during times when stream water is unavailable.
(2) Equip and connect an existing proven well to the Water District system (power & watermain). Testing has shown this well will also require treatment (ozonation) for iron and manganese content. This additional well will increase available water supplies by approximately 13 acre-feet per year (AFY) and provide the necessary supplemental water when the stream diversion is unavailable. Associated improvements include installation of a 50± square foot equipment shed, PG&E connection, trenching and underground wire/piping connection within an existing easement.
(3) Replace the containment roof on an existing (c1973) 60,000 gallon in-ground gunite water tank with an engineered metal roof. The wooden roof on this tank reached the end of its useful life in 2020 and was removed. The loss of this tank could not have come at a more inopportune time. In the project, this is where the water from the Task 2 well will be treated, stored, and enter the Irish Beach Water District system.
