Irvine approves one-year extension of county waste agreement after negotiations reduce near-term truck impacts from Bowerman landfill

The Irvine City Council voted unanimously on June 24 to approve a one-year extension to the county Waste Disposal Agreement (WDA), a move city staff said preserves current landfill rates and buys time to pursue a longer-term solution to truck traffic and other local impacts tied to Bowerman Landfill.

City staff briefed the council on a county plan that will lower the amount of out-of-county (imported) daily tonnage arriving at Bowerman from roughly 2,150 tons per day to about 800 tons per day beginning July 1. Staff said that change, together with county rebalancing that shifts some North County deliveries to the Prima Deshecha landfill in San Juan Capistrano, avoids an immediate 40% increase in daily trash-truck trips into Irvine that had been anticipated when the Olinda-Alpha (Brea) landfill is scheduled to reach its regulatory height limit in 2026.

Background and why the extension was proposed: Bowerman is the county’s largest landfill, permitted for up to 11,500 tons a day. City staff told the council that, without a WDA extension, the City of Irvine would face immediate financial and logistical consequences: the county’s non-WDA disposal rate is higher (staff cited $43.76/ton under WDA rates versus $68.25/ton without WDA), which the city estimated would translate to a minimum residential trash-bill increase of roughly 22.7% (about $5.10/month) and possibly above 30% ($6.85/month) if out-of-county disposal had to be sourced outside Orange County. The city also would lose an estimated roughly $800,000 in annual revenue share tied to out-of-county trash under WDA terms.

Negotiations and the longer-term solution: City staff outlined a multi-year plan to secure a longer-term fix that would include designing and obtaining approval for a direct on/off ramp to Bowerman from the 133 toll road (a Bee Canyon interchange) that would route landfill truck traffic off local streets. Staff estimated design and approvals could take four to six years; the county’s recent rebalancing of tonnage “buys” the city time to pursue that capital solution while the WDA remains in place.

Public testimony and concerns: Residents who live near the landfill testified about ongoing odor, road wear and safety, and concerns about increased truck traffic if Brea closes and Bowerman’s daily intake is increased. Michelle Johnson, representing nearby residents, urged a longer-term negotiation with outside counsel and consultants so the city could obtain “achievable, legal and enforceable” alternate haul routes, and urged a transparent process. In response, staff said they had recently reopened discussions with county staff and that the county had agreed to immediate reductions in imported tonnage that reduce the near-term truck-volume spike.

Council action: After staff outlined the risks of not extending the WDA and explained the county’s near-term operational changes, the council voted 7-0 to approve the one-year extension and to continue negotiations with the county. Council members asked staff to return with a strategic plan and recommended outside consultants/legal support so the city could pursue enforceable routing and mitigation measures during the one-year extension period.

Why it matters: The extension preserves lower disposal rates and revenue sharing for Irvine households and municipalities while avoiding an immediate spike in landfill truck traffic through residential streets. It also launches a focused negotiation phase to address longer-term mitigation of traffic, environmental impacts and community concerns as county landfills change operations.

Ending: City staff said they will return to council in a matter of weeks with a proposed plan for outside expert assistance and a timeline for the interchange design and permit efforts. The city emphasized that the agreement extension is strictly procedural and preserves current service and cost levels while negotiations continue.
