Casa Grande council approves $4.2M lift‑station contract, OKs ADOT roundabout agreement

The Casa Grande City Council approved two infrastructure items at its meeting: a $4,199,000 construction contract with Hensel Phelps Construction Company for the Quartz & West regional sewer lift station, and an intergovernmental agreement with the Arizona Department of Transportation (ADOT) to administer a federally funded roundabout project at Florence Street and Ash Avenue.

The first vote authorized a contract award to Hensel Phelps and included a requested contingency of $504,000 to cover potential cost increases. City staff said the lift station will collect and pump wastewater from the West Side to the existing water reclamation facility to support planned commercial, industrial and residential development. A city staff member identified as Mac said the project faces an atypical supply‑chain constraint for electrical equipment: "we're looking at about a 500‑day timeline" because of lead times for backup generators that are "required per Arizona law." Mac added the city could put rental generators in service sooner if necessary, "but that would just have additional cost impacts to the project," explaining the rationale for the contingency request.

The council approved Resolution No. 5761 to accept the Hensel Phelps bid and authorize contract execution. The roll call showed seven affirmative votes and no dissent (Romo, Dugan, Bedellin, Edwards, Huddleston, Mayor Pro Tem Herrmann, Mayor Fitzgibbons), and the resolution passed.

On the second item, staff recommended the city enter an intergovernmental agreement with ADOT so ADOT can administer construction of a roundabout at Florence Street and Ash Avenue using federal funds. Dwayne, a city staff member, described the project scope as construction of a roundabout with curb ramps, crosswalks and sidewalks and said it would "improve traffic circulation, and address safety concerns." When asked why ADOT must administer the project, Dwayne said, "For construction with federal funds, we have to have ADOT administer it." He and council members discussed roundabout safety advantages and lower long‑term maintenance costs compared with traffic signals.

Council approved Resolution No. 5763 authorizing the ADOT intergovernmental agreement. The roll call recorded seven affirmative votes and no dissent (Grama, Dunye, Bridal, Edwards, Huddleston, Mayor Pro Tem [name transcribed as] "Tempeperman", Mayor Fitzgivens as recorded in the roll call). The resolution passed.

Both approvals carry implementation conditions noted by staff. For the sewer lift station, staff said construction could be completed but remain offline if permanent generators are delayed; rental generators are the contingency option. For the roundabout, the city will retain responsibility for design work while ADOT administers construction because the project uses federal funds. Staff cited an estimated total project cost for the roundabout of about $3.5 million ("plus or minus"), and said the design is complete.

Votes at a glance

• Resolution No. 5761 — Accept bid and authorize contract with Hensel Phelps Construction Company for the Quartz & West regional sewer lift station; contract bid $4,199,000; contingency $504,000 requested; outcome: approved (7–0).

• Resolution No. 5763 — Authorize intergovernmental agreement with the Arizona Department of Transportation to administer construction of a roundabout at Florence Street and Ash Avenue; estimated cost ≈ $3.5 million; outcome: approved (7–0).

Both measures direct staff to proceed with contract execution and coordination consistent with the agreements; no additional council direction or amendments were recorded at the meeting. Staff warned the lift‑station schedule faces medium implementation risk because of generator lead times; the city identified rental generators as a contingency to put the station into service sooner if needed.

Clarifying details from the meeting: the lift‑station base bid reported in the agenda was $4,199,000 with an additional requested contingency of $504,000; staff estimated a potential 500‑day timeline driven by backup generator lead times but noted typical lift station projects take 9–12 months; ADOT must administer construction when federal funds are used, though the city completed design work for the roundabout. The transcript did not specify final total appropriation amounts beyond the bid and contingency figures, nor did it list contract start or guaranteed completion dates.
