Azusa Rock Quarry/Modification to C-89-20, Development Agreement and Revised Reclamation Plan

NOTE: Reference SCH# 1999041005 The project includes an update to the existing conditional use permit ("CUP") and reclamation plan to allow for: 1) a state-of-the-art reclamation program to reshape, revegetate, and naturalize the appearance of the benches and terraces of the east and west quarry faces, including microbenching, recontouring and revegetation with native species; 2) the acceleration of reclamation activities for the east portion of the site; 3) the mining and reclamation on the westernmost 80-acres of the site in lieu of the easternmost 80-acre site; 4) the inclusion of the 8-acre western portion of the site in the reclamation plan; 5) an increase in the capacity of an on-site detention basin from approximately 1.1 acres to approximately 1.45 acres (basin depth to remain at its current elevation); and 6) the relocation of the existing hiking trail from the western 80-acre portion of the site to a location allowing for a comparable or better trail. Mining will still continue until 2038 as permitted, but the reclamation timeline will be accelerated to improve the aesthetic appeal of the site.
