Mission Valley Quarry Pending Projects

The County of Alameda (County) is processing the Mission Valley Quarry (SMP-32) Reclamation Plan Amendment (RPA).  The Alameda County Transportation Commission (ACTC), in cooperation with the California Department of Transportation (Caltrans), is proposing to widen Interstate 680 (I-680) in the southbound direction along the eastern border of SMP 32. This freeway widening will require the Permittee, Lehigh Hanson, to remove 5.51 acres from SMP 32, along the eastern boundary, adjacent to the I-680 Right-of Way. The purpose of the RPA is to modify the boundary of SMP 32 to remove the acreage that will be used for the freeway widening.  The RPA also includes a focused landscaping plan for a 2.47-acre portion of the site.  The County will also be revising conditions to approval to incorporate the focused landscape plan into the approved reclamation plan.

The boundary modification figure and Focused Landscape Plan may be found here:
