Glendale planning staff on Aug. 12 presented a public hearing on a proposed annexation of 39 acres along the Agua Fria River for the 3 Rocks Mining Phase 2 project, and the City Council scheduled a formal vote on the annexation and related zoning for Aug. 26, 2025.
The proposal, presented by Glendale principal planner Dwayne Hoskins, covers ground roughly eight miles west of City Hall between the Bethany Home Road and Maryland Avenue alignments. Hoskins said staff filed a blank petition on July 16, 2025, and described the applicant’s plan to mine aggregate for about 10 years and then “restore and rezone for mixed use residential, commercial, and industrial development.” Hoskins confirmed the parcel is 39 acres.
The petition would bring the site into the city with initial zoning of R-R 45 (rural residents) while the applicant simultaneously seeks rezoning to heavy industrial with a special-use overlay. The site is currently accessed from Cirrus Road near El Mirage and West Keene Drive and is surrounded by existing mining operations, Hoskins said.
Because item 24 was a public hearing only, the council did not take a vote on Aug. 12. Council members asked no substantive questions during the hearing; Hoskins concluded his presentation and the mayor closed the public hearing. A council vote on the annexation and subsequent zoning actions is scheduled for Aug. 26, 2025.
The Aug. 26 vote will determine whether the city accepts the annexation and whether the parcel’s zoning will change from the city’s rural-residence designation to heavy industrial with a special-use overlay, a change that would allow the proposed multi‑phase mining operation before later redevelopment.
