Document Description
The California Department of Transportation (Permittee) proposes to conduct the following: Horse Creek Bridge – Location 1, the Project is limited to the following; implement traffic control, installation of cut-off walls, repair of concrete spall, and installation of staging and access areas. Install temporary access road and staging areas, install temporary creek diversion system (TCDS). Add Portland cement concrete cut-off walls at both sides of Abutment 2 and the right side of Abutment 1. Cut-off walls will extend down 5 feet below existing grade, backfill abutments and wingwalls with approximately 4,875 square feet of rock slope protection (RSP) (0.25-T-size rocks approximately 2 feet deep). Repair concrete spalling on deck, remove TCDS and install erosion control. McCune Creek Bridges – Location 2. remove one willow tree and one Chinese elm tree, located north of the westbound bridge at McCune Creek. Implement traffic control during the installation of the pile jackets, replacement of the longitudinal joint seals between the old and new structures, replacement of the lateral joint seal, repair of the concrete spalling, and installation of staging and access areas. Install temporary access road and staging areas. Install TCDS, excavate as needed and rebuild abutment slope embankments with engineered backfill and place RSP from the toes of slopes up to the abutment pile caps to prevent erosion. Pressure-pump grout or cement from underneath the deck or use of shotcrete to fill voids at the abutments. Once all the voids are filled, install RSP up to the pile cap/bridge soffit. Excavate 5 feet maximum around the columns at the bents. Install a fiberglass reinforced polyester and concrete jacket to the 30 existing, exposed 16-inch-diameter Raymond piles, new pile diameter will be 26 inches. Concrete will be pumped into the new pile jacket to fill the void between the new pile surface and the existing Raymond pile. The fiberglass reinforced polyester jackets will be installed up to 5 feet below original grade. Replace longitudinal and lateral joint seals on the bridge superstructure. Repair concrete spalling on deck. Remove TCDS, install erosion control and landscaping. Location 1 has a 6.14-acre Biological Study Area (BSA) that encompasses Horse Creek and Location 2 encompasses a 6.09-acre BSA that for McCune Creek that incorporates all of the Caltrans Right-of-Way (ROW), collectively, the Project Area. The Project is expected to cause the permanent loss of 0.003 acres of foraging habitat for the Covered Species and the temporary loss of 0.582 acres of foraging habitat for the Covered Species at Horse Creek (Location 1) and permanent loss of 0.015 acres of foraging habitat for the Covered Species and the temporary loss of 1.016 acres of foraging habitat for the Covered Species at McCune Creek (Location 2). The Project will also result in the removal two riparian trees at McCune Creek. This Project is expected to cause the potential loss of only one (1) known nesting occurrence within the Project Area of both locations. Project activities and their resulting impacts are expected to result in the incidental take of individuals of the Covered Species. The activities that are expected to result in incidental take of individuals of the Covered Species include initial site setup, equipment and material delivery, clearing and grubbing, site preparation, exclusionary fencing installations, environmentally sensitive area fencing installations, pavement and concrete removal, concrete pump truck activities, vibratory driving of sheet piles, bridge maintenance and repair, soil excavation, soil compaction, grading work, pavement installation, heavy equipment operation, trenching, construction vehicle traffic, general vehicle traffic and personnel on foot The project is expected to result in incidental take of Swainson’s hawk take as defined by Fish and Game Code in the form of adverse impacts from excessive noise from the operation of heavy equipment and encroachment from individuals on foot that may result in nest abandonment and the loss of Covered Species eggs or juveniles, or in the form of capture to recover and transport injured Covered Species to care facilities of Swainson’s hawk, designated as a threatened species under CESA. The ITP referenced above as issued by CDFW authorizes incidental take of species listed under CESA that may occur as a result of Project implementation.
