Prescott Valley council awards $16.3 million in construction and related contracts for Glassford Hill Road and approves $659,358 stormwater-recharge study

Council voted on Jan. 8 to advance two infrastructure priorities: the Glassford Hill Road Long Look Drive to State Route 89A widening project and a stormwater-recharge field trial.

Glassford Hill Road: Public Works engineer John Laba described a 2.3-mile project widening the arterial to three northbound and three southbound lanes, adding a 10-foot multiuse path in sections, resurfacing and signal upgrades. The project budget combines a $9.9 million state allocation with impact fees, sales tax and other local sources. Council approved four related motions by electronic vote: a construction contract with Asphalt Paving and Supply Inc. for $13,933,333.33 (with a 10% owner contingency), a $165,040 post-design professional-services agreement with Kimley-Horn, a $627,864.68 cooperative agreement with Quality Testing LLC for construction inspection and testing, and a $115,400 survey/staking services agreement with Lion Engineering. Votes were recorded and passed as read.

Stormwater recharge: Staff presented a time-and-materials professional-services agreement with West Consultants for a field trial to build and instrument two basins (control and test) in the Pronghorn 21 area to compare infiltration performance. The contract is for $659,358 and the study duration was described at roughly 1.5–2 years with monitoring and a final report. Council approved the agreement by electronic vote.

Next steps: Staff will proceed with contract execution and project scheduling; Glassford Hill construction is anticipated to take approximately nine months, subject to weather and delays. The stormwater recharge trial will produce monitoring data and a final study to inform potential wider use of the technology.
