Document Description
The County is proposing to upgrade 3 and install 2 new stream gaging units to record streamflow data in the Napa River (at Calistoga) and 4 tributaries in the Napa River Watershed (Milliken Creek, Redwood Creek, Dry Creek and Conn Creek). Streamflow data will be made publicly available via the California Data Exchange Center as per the requirements of the California Department of Water Resources grant. This project will rely on tying into existing Napa County Flood Control & Water Conservation District OneRain sensor infrastructure at 3 of the 5 sites. Stream gage equipment will be paired with and installed within this existing OneRain telemetry infrastructure. Two locations (Conn Creek at Skellenger Lane, and Dry Creek at Solano Avenue) will require the installation of new gaging stations. The Project sites, consisting of existing streams and creeks, likely support local movement patterns of terrestrial wildlife
species and provides food and cover resources for common avian and amphibian species, especially those areas near ephemeral drainages and streams. Temporary effects due to noise and increased human activity during Project activities should not interfere with these local movement patterns over time or affect the ability of these species to forage or reproduce. No removal of vegetation and no earth disturbance is proposed. Furthermore, work will occur outside the bird nesting season so there is no potential impact to nesting birds and raptors protected under the Migratory Bird Act.
Additionally, various Best Management Practices are proposed to be implemented to reduce any impacts.

Reasons for Exemption
The County finds that the proposed Project activities fall within Section 15304, Minor
Alterations of Land, Class 4, Section 15302, Replacement or Reconstruction, Class 2 exemptions, and Class 6 Section 15306 Information Collection. The Project involves a limited number of minor, temporary, and localized alterations in the condition of the land and vegetation for the purposes of data collection, with no removal of any healthy, mature or scenic trees and no serious or major disturbance to any environmental resource. See attached CEQA memo for further analysis and discussion. None of the exceptions set forth in Section 15300.2 of the CEQA Guidelines apply. As a result, the proposed Project is categorially exempt from CEQA. The project sites are not listed on any hazardous waste sites enumerated under Government Code Section 65962.5.
