The Department of the Army, US Army Corps of Engineers, San Francisco District has a requirement for Reach 6 levee and floodwall construction along the Corralitots Creek, a tributary of the Pajaro River Levee System in the City of Watsonville, County of Santa Cruz.

Established by Congress in 1905, the mission of the Forest Service is to sustain the health, diversity, and productivity of the nation’s forests and grasslands to meet the needs of present and future generations. We manage public lands in the form of
National Forests and National Grasslands, provide technical and financial assistance to state and private forestry agencies and make up the largest forestry research organization in the world.

• This project is for the Reach 6 levee and floodwall construction along the Corralitots Creek, a tributary of the Pajaro River Levee System in the City of Watsonville, County of Santa Cruz. The Project consisting of 2.6 miles of flood risk management levees with approximately 111,600 compacted cubic yards (cy) of fill, and 1,500 ft of floodwalls.
• The Pajaro FRM Project consists of from Reach 2 to Reach 6 of the Pajaro flood control system. This ITB is for Reach 6 of the Pajaro FRM Project. The project area is located within the lower Pajaro River watershed. It encompasses an area of approximately 10,000 acres, which includes the stream channels, active floodplains, and terraces along the Pajaro River and the Salsipuedes and Corralitos Creeks. The area is divided by the Pajaro River, which serves as a border for two counties. Santa Cruz County lies to the north of the Pajaro River, and Monterey County lies to the south. The Salsipuedes and Corralitos Creeks, which join just north of the Pajaro River in Santa Cruz County, are tributaries of the Pajaro River. The engineered levees have a crest elevation of ranging from 2 to 8 feet, a minimum crest width of 20 feet, and 3H:1V side slopes.  The access road, on top of the levee, will be surfaced with a minimum of 8 inches of CalTrans Class 2 Aggregate Base.  Structural features included in the contract include 1,500 LF of 6 ft to 9 ft high floodwall walls. The Highway 152 Bridge will be raised approximately 6 ft and it is a separate project. The first 100 ft from boarding the bridge are left for future construction with the bridge. Construction for Reach 6 is likely to be performed across the at two construction seasons.  See Attachment 1 for Site Map.
• There are two side channels designed to enhance eco-system restoration in the Project. The material excavated from the channels is not suitable to be used for the engineered levee along. Suited soil will be imported offsite to blend with the excavated soil for levee fill.
• The site has limited access. Some of the ingress/egress are through unpaved dirt roads in farm fields. Attachment 2 shows permanent easements, staging area and hauling routes. Material from excavation will be stockpiled and mixed with imported soil onsite.
