NOE - Notice of Exemption
The Project is limited to the conversion of approximate 200 foot long open channel drainage into a culvert piped drainage system. The new drainage system will consist of an inlet protection field of quarter ton rip-rap, 20 feet long and 8 feet wide, followed by a concrete headwall approximately 5 feet tall, 8 feet long, and 4 inches wide. The system will also consist of a 150 feet long concrete reinforced steel pipe followed by a second headwall 5 feet tall, 8 feet long, and 4 inches wide with an outfall dissipation structure of quarter ton rip-rap approximately 20 feet long and 8 feet wide. The top of the pipe will be covered with native soil. Issuance of a Streambed Alteration Agreement Number 1600-2013-0326-R3 is pursuant to Fish and Game Code Section 1602.
The Project is exempt from CEQA because it consists of the reconstruction of an existing structure where the new structure will be located on the same site as the structure being replaced and have substantially the same purpose and capacity as the structure being replaced.
