Document Description
Lake County Special Districts is seeking grant funding to analyze the existing Spring Valley distribution system and obtain recommendations. No development or infrastructure improvements are proposed at this time. One of the challenges that the system now faces is the wide range of pressures throughout the distribution system. The Spring Valley water distribution system is served by a single storage tank which is supplied by the surface water treatment plant on Wolf Creek Road. Due to the topography throughout the district and the current configuration of the distribution system pressures remain relatively high ( 145-185 psi) and moderately high (80-135 psi) throughout a majority of the system. The installation of master pressure reducing valves in the distribution system is currently impractical due to the need to maintain minimum pressures in adjacent areas of the system. The high pressures throughout the system increase Operations and Maintenance costs, increase the amount of water lost when leaks occur, and can cause tremendous problems for the public if their customer installed pressure reducing valves fail. The District is seeking an updated water model of the system and recommendations for improvements which would allow appropriate pressure zones to be established to reduce the service pressure delivered to the end user. See attached system map.

Reasons for Exemption
Class 6 consists of basic data collection, research, experimental management, and resource evaluation activities which do not result in a serious or major disturbance to an environmental resource. These may be strictly for information gathering purposes, or as part of a study leading to an action which a public agency has not yet approved, adopted, or funded. Special Districts is seeking grant funding to analyze the system and obtain recommendations. No development or infrastructure improvements are proposed at this time. Once a recommendation and design are developed, the project will be analyzed for environmental impacts, subject to CEQA, as applicable. No exceptions listed under Section 15300.2 apply. There is no reasonable possibility that the project would have a significant effect on the environment.
