Justin Lucas, chief of operations and infrastructure for the Ada County Highway District, told the Eagle City Council that ACHD is circulating a draft 20‑year transportation capital improvements plan and related impact‑fee study and is seeking written and oral comments before the commission adopts a final version.

The draft changes two long‑standing program elements: it proposes to move from a single countywide impact‑fee service area to a two‑service‑area model split roughly along Cole Road, and it lays out roadway projects that feed fee calculations. ‘‘This is a 20‑year plan,’’ Lucas said. He added that, under Idaho law, transportation impact fees may be used only for new capacity such as arterial widening and not for maintenance.

Lucas showed sample fee differences under the two‑area approach: a single‑family home in the West Service Area (which includes most or all of the City of Eagle) was estimated at $8,929, while the East Service Area fee was shown at $5,348. Lucas said the discrepancy is driven by the number and cost of projects assigned to each area.

Lucas also described a construction project ACHD is starting in Eagle: Linder Road between State Highway 44 and Floating Feather, including a new roundabout at Linder and Floating Feather and a five‑lane widening. ‘‘There are two schools along this corridor,’’ he said, noting outreach with homeowners associations, school principals and an open house planned for Nov. 6 at Galileo STEM Academy. Lucas said ACHD awarded the construction contract to Granite Excavations on a bid ‘‘a little over $10,000,000,’’ which he described as below previous engineer estimates and post‑COVID peaks.

ACHD will separate landscaping from the roadwork and re‑bid planting later. Lucas said utilities and excavation will push construction through the following spring and summer, with landscaping done near the end of the project and overall completion hoped for about a year after start, weather permitting.

The council asked questions about outreach, school‑time traffic observations and community meetings; Lucas said ACHD will assign a project inspector on site and hold regular construction meetings for adjacent businesses and residents.

Why it matters: the draft CIP and impact‑fee ordinance would change how and where new development pays for added road capacity in Ada County. The Linder Road project will materially affect traffic patterns and access near two schools and other corridor land uses while adding capacity paid in part by impact fees.
