Notice of Exemption

Exempt Status
Categorical Exemption
Type, Section or Code
Class 2, §15302; Class 3, §15303; Class 4, §15304
Reasons for Exemption
Class 2 covers replacement or reconstruction of existing utility systems and/or facilities involving negligible or no expansion of capacity; Class 3 covers construction and location of limited numbers of new, small facilities or structures; and Class 4 covers minor trenching and backfilling on land with a slope of less than ten percent where the surface is restored. The project is consistent with the categorical exemptions noted above because work would consist of replacement of existing water meters and meter boxes, replacement of existing water mains, and installation of fire hydrants. Although the new water mains would be larger than the existing mains, the existing mains are undersized for existing conditions, and larger mains are required to meet minimum California Waterworks Standards and to achieve adequate fire flows. Improvements would occur in previously disturbed areas within public road ROW. Paved areas disturbed during installation of the improvements would be repaved following construction. As documented in Attachment A, the proposed project would.not have a significant effect on the environment due to unusual circumstances; would not result in damage to scenic resources within a Scenic Highway; is not located on a hazardous waste site pursuant to §65962.5 of the Government Code; would not cause a substantial adverse change in the significance of a historical resource; and would not result in cumulative impacts.
