Install Culvert Across Connector Trail
Document Type
NOE - Notice of Exemption
Document Description
Install a new 12-inch diameter by 6 foot long high-density polyethylene (HDPE) culvert pipe across a popular connector trail located in the Mitchell Canyon Day Use Area. This trail connects the upper parking lot and Bruce Lee Trail to the Mitchell Canyon Fire Road. The project area is situated at a point on the connector trail, where the trail crosses an ephemeral swale that has suffered from erosion. Excavate the soil material used for the trail to a depth of approximately 24 inches for culvert placement. After fitting the culvert pipe, install filter fabric and rock armorment as necessary to protect the two inflow and outflow points of the culvert from erosion. Replace soil material excavated from the trail. Culvert installation repairs the connector trail and is situated within the existing trail alignment. Equipment staging and storage areas are located on existing graded gravel and paved surfaces. There are no known cultural resources in the project area.
