CA FLAP SCR-T5(1A) MBSST-Mitigation-100 Percent Plans Phase1.pdf

This document is a Plans for Proposed project package for the Monterey Bay Sanctuary Scenic Trail Mitigation (CA FLAP SCR T5(1A)) prepared by the U.S. Department of Transportation Federal Highway Administration. The project involves mitigation site restoration and enhancement in Santa Cruz County, California, spanning multiple restoration areas including Arroyo Willow Riparian Forest Restoration (RFR-1 through RFR-6) and Palustrine Emergent Wetland (EW) restoration.

The project includes comprehensive work across site preparation, grading, erosion control, invasive species removal, and extensive plantings of native vegetation. Key deliverables include selective clearing and invasive exotic plant removal (0.38 to 1.21 acres depending on restoration area), site grading (5,850 to 6,500 square yards), combination wire-cattle exclusion fencing (269 to 1,881 linear feet), and cattle exclusion gates (2 to 5 per location). Planting requirements are substantial, including multiple native species such as California blackberry, bog rush, dense sedge, Monterey sedge, salt marsh baccharis, arroyo willow, and Pacific willow, with quantities ranging from 22 to 620 trees per restoration area. The project also requires specialized labor for technical services, biological monitoring services, and survey services over an 80-hour allocation. All work is scheduled for completion by February 28, 2028, with mobilization and construction activities to commence immediately upon project initiation. The plans include detailed specifications for cattle exclusion fence design, planting details with specific spacing requirements, and grading specifications for wetland site preparation.
