Laramie council approves TriHydro contract to design landfill cells and front entrance improvements
Summary
The Laramie City Council voted 9–0 to award TriHydro Corporation a professional services agreement to design expansion of landfill Cells 3A/3B (and add design for Cells 4A/4B) and assess the landfill front entrance. Council discussion focused on staging, traffic queuing at the entrance and the RFQ‑based selection process.
The Laramie City Council on Dec. 2 approved a professional services agreement with TriHydro Corporation to design work at the city landfill and to evaluate the site’s front entrance.
Councilor O'Doherty moved to award the contract “for landfill Cells 3A and 3B, leachate pond and front entrance project for $218,154.50” and to authorize the mayor and city clerk to sign; the motion was seconded and passed on a 9–0 roll call. Director Webb told the council that, because TriHydro’s negotiated cost came in under budget, staff asked the firm to add design work for Cells 4A and 4B so the city could take advantage of current prices.
The project combines two previously separate efforts — cell expansion and a front‑entrance evaluation — so a single engineer can avoid conflicting designs, Webb said. The front entrance, Webb noted, was constructed in 2012 and weekday and weekend traffic — especially Saturdays when residents bring green waste and compost — can queue onto Rogers Canyon, creating safety and congestion concerns. The consulting team will examine options to increase queuing space and reduce backups.
Councilors pressed for technical and procedural details. O'Doherty asked about the typical lifespan of a landfill cell; Webb said stage‑by‑stage planning shows roughly 32 years remaining in the current stage and noted that annual evaluations consider compaction, waste types and diversion rates. Councilor Newman asked why adding Cells 4A/4B did not trigger a rebid; Webb explained the process was a Request for Qualifications (RFQ), which selects consultants on qualifications rather than initial price and allows negotiations following selection.
Councilor Bowling asked whether the motion should reflect the expanded scope; Webb replied that the budget title is still Cells 3A and 3B and scope changes are a normal part of project development. The roll call showed nine yes votes and zero no votes.
Next steps: staff will finalize the professional services agreement with TriHydro and return any required documents for signature by the mayor and city clerk.
