Document Description
The Project includes the development of a hard rock quarry pit and associated infrastructure to mine rock aggregate and the realignment of Americano Creek at the quarry site to allow for upgrading of Roblar Road; upgrading approximately 1.6 miles of Roblar Road and construction of a 0.4 mile long private access road connecting Valley Ford Road and Roblar Road; and enhancement of California tiger salamander (Ambystoma californiense) habitat. The Project will proceed in four phases, an initial phase to construct the hard rock quarry pit infrastructure, upgrade Roblar Road, and construct the private access road (Initial Phase), and three quarry mining phases (Phases 1, 2, and 3). The Initial Phase and Phase 1 activities include the excavation and grading of the initial processing area; installation of a sediment pond and other drainage features; and construction of an office, equipment storage area, small parking lot, and two irrigation fields. The two irrigation fields will consist of aerial sprinklers or subsurface emitters, which will impact approximately 20% of the total area of the irrigation fields. The Initial Phase also includes the Roblar Road upgrades; consisting of the widening of Roblar Road to 11-foot-wide vehicle travel lanes with three-foot-wide paved shoulders, and two-foot-wide rock shoulders at the edge of the pavement; and construction of a private access road connecting Valley Ford Road and Roblar Road. Approximately 570,000 cubic yards of quarry material will be mined from the Project site annually. Project activities include grubbing and grading of undeveloped land, trench digging, tree removal, installation of exclusion fencing, excavation, and road construction within the 110.40-acre Quarry. An additional 13.25-acres of development is associated with the Roblar Road upgrades and the construction of a private access road connecting Valley Ford Road and Roblar Road, resulting in a 123.65-acre Project footprint.
The Project will result in impacts to 86.30 acres of California tiger salamander habitat including permanent impacts to 85.80 acres of upland habitat and 0.34 acres of breeding habitat and temporary impacts to 0.16 acres of upland habitat. The project is expected to result in incidental take of California tiger salamander, which is 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.
The current amendment, Amendment 1, extends the date by which the Permittee must either purchase 193.11 acres of Covered Species credits from a CDFW-approved mitigation or conservation bank OR provide for both the permanent protection and management of 193.11 acres of Habitat Management lands from 18 months to 30 months after the effective date of the ITP if Security is provided.
