Reasons for Exemption
The District proposes to continue their ongoing program to replace aging and undersized water system infrastructure. The purpose of the proposed Project is to improve water service flows, improve customer water quality, improve fire protection and reduce water losses from leaks, while minimizing the need for future maintenance. The proposed Project would not increase the capacity of the water system, but rather update the undersized infrastructure system to adequately support the existing capacity and provide adequate fire protection. There are no new customer service connections anticipated, as the lots are already developed and there is no room for further expansion. The National Fire Protection Association Code provides regulations under NFPA 13 Section 184.108.40.206 stating “Private fire service mains must be at least 6-inch diameter where they supply hydrants” and under NFPA 24 Section 13.1 stating “Pipe smaller than 6 inch in diameter shall not be installed as a private service main supplying hydrants.” Discharge water flow rates would remain the same regardless of the new waterlines and service connections. Therefore, the proposed Project would not increase the capacity of the water distribution system. The new pipelines would not be able to support more than the planned services for the area and would not encourage future growth, so as to require an expansion in capacity. The proposed Project would merely replace the existing infrastructure in order to meet existing daily demand as well as improve water quality, fire protection, and efficiency. Therefore, the Project is consistent with the example provided in 15302(c), as the replacement of the pipelines would result in no expansion of capacity.
