Document Description
The community of Penngrove is located east of Highway 101, south of the City of Cotati and north of Petaluma. A significant number of vehicles use Petaluma Hill Road and Old Redwood Highway as an alternate north-south route. As a result, intersections around Penngrove face significant congestion during peak hours. Sonoma County is currently working on a project to improve safety and efficiency at
the intersection of Adobe Road and Main Street/Petaluma Hill Road. The County now seeks to improve Old Redwood Highway at the Ely Road and Railroad Avenue intersections. Together, the improvements at these three intersections will improve the flow of traffic for the Penngrove community and along the Old Redwood Highway and Petaluma Hill Road corridors.

Notice of Exemption
Exempt Status
Categorical Exemption
Type, Section or Code
Section 15302 (Class 2)
Reasons for Exemption
The Project is exempt from CEQA under Section 15302 of the CEQA Guidelines. A Section 15302 (Class 2) exemption applies to replacement or reconstruction of existing structures and facilities where the new structure replaced will be located on the same site as the structure replaced and will have substantially the same purpose and capacity as the structure replaced. The Project is consistent with a Class 2 exemption because the Project will reconfigure the the intersection of West Railroad Avenue and Old Redwood Highway in the same place as the existing intersection, and will not alter the operational conditions of the intersection. The Project would not trigger any exceptions to the use of a Categorical Exemption, as stated in Section 15300.2 of the CEQA Guidelines.
