Council reviews cost options for paving Redwood and Chestnut; annexation raises complications

City staff presented a range of cost estimates for upgrading Redwood and Chestnut roads and discussed the complexities of annexation and property ownership that would affect project scope and cost.

Staff said the full-build estimate in the 2021 annexation study, including curb, gutter, sidewalks, storm sewer and utilities, was roughly $6.6 million for the roads alone and more than $8 million when related trail work and other items were included. A reduced-scope option that would prepare proper roadway base and paving was estimated at about $4.0 million, a figure that included engineering, contingency and administrative costs. A lower-cost option limited to placing an asphalt mat over existing roadway (without subgrade work) was presented at about $1.1 million; removing the contingency lowered that figure to roughly $955,000.

Why it matters: staff cautioned that the overlay-only approach would not address known subgrade and frost-susceptibility problems on those routes and likely would not last as long under heavy traffic, including school buses and semitrailers. The more comprehensive reconstruction would address underlying base and drainage but carries a substantially higher price tag and would include a contingency, engineering fees and legal administration.

Annexation complications: staff explained that many rural parcels adjoining the roads are platted to the road centerline, meaning the city would need to work with about 16 different property owners to secure annexation or easements. Councilors and staff noted that annexation can trigger special-assessment questions and could create the conditions for future forced annexation of properties that become surrounded by the city.

Community engagement: A resident is organizing stakeholders including the school, township and county for a meeting to discuss road options; staff said they are open to a multi-stakeholder meeting similar to prior cooperative projects and will coordinate dates.

Outcome: No formal council action was taken; staff provided cost tables and agreed to participate in stakeholder discussions. Councilors asked staff to share any alternate cost estimates the group may have.

Quotes from the meeting: "If the city was just going to... put in the proper base etcetera, it's going to be about $4,000,000," a staff member said while reviewing the annexation study figures. "If you just put a 3.5-inch mat on it, you're still talking about close to a million dollars," staff added, noting that the overlay would not resolve frost-related subgrade issues.
