Diamond Bar meeting summaries, agendas, and minutes

Diamond Bar agendas: 49-unit condo proposal, parcel map hearing, $1.8M check register

Diamond Bar's City Council and two city commissions were scheduled to take up a tentative parcel map, a 49-unit condominium proposal and a review of traffic statistics over the past two weeks, according to the agendas for those meetings. An agenda lists what a body intends to consider; minutes recording what was actually decided have not been published for any of the three meetings, so the documents available do not show the outcomes.

City Council, Oct. 6: parcel map hearing

The council was scheduled to meet at 6:30 p.m. at the South Coast Air Quality Management District Main Auditorium, 21865 Copley Drive, with a public hearing on Tentative Parcel Map No. 83773 (Case No. PL2022-119). The agenda called for consideration of Resolution No. 2026-32 to approve the map and a Mitigating Negative Declaration.

The consent calendar listed approval of the Sept. 15, 2026 regular meeting minutes and ratification of a check register covering Sept. 9–22, 2026 totaling $782,547.57. Also listed were a City Manager report on El Niño preparedness, a Certificate of Recognition to Aditi Chawla, and future events including Measure Q informational presentations on Oct. 12 and 17.

The commission scheduled a public hearing on a proposal to demolish an office building and construct 49 condominium units on a 3.9-acre site at 1400 Montefino. The agenda listed four related land use actions for the commission to consider:

• A General Plan Amendment changing land use from General Commercial to Medium High Residential

• A Conditional Use Permit to reduce parking from 165 to 120 spaces and open space from 30% to 12%

The agenda does not record what the commission did with any of these items.

Traffic and Transportation Commission, Oct. 15

The commission was scheduled to review traffic statistics for July 2025/2026 and August 2025/2026, along with updates on various projects and programs. No further detail on the statistics or the projects was included in the agenda summary.

Coming up

City Council, Oct. 20. The council is scheduled to ratify a check register covering Sept. 23, 2026 through Oct. 6, 2026 totaling $1,839,831.83, and to approve the September 2026 Treasurer's Statement. Also on the agenda: adoption of a proclamation declaring October 2026 as Hindu Heritage Month, recognition of the 2026 Through My Lens Photo Contest Winners, and a San Gabriel Valley Council of Governments 57/60 update.

Both check register items are ratifications, meaning the council is asked to confirm spending already listed in the register. The agenda summaries do not itemize the individual payments within either total.

Residents can attend the Oct. 20 council meeting; the agenda summary provided does not list a location or start time for that meeting.
