Eagan staff propose ‘rejuvenator’ surface treatment and modest assessment changes to extend street life
Summary
Public‑works staff proposed extending pavement life (target ~100 years) using a rejuvenator surface treatment, a pilot test this summer, and adding curb‑and‑gutter to assessable costs; staff estimates an average residential assessment increase of about $60 and plans to return feasibility reports and assessment hearings this fall.
Public‑works staff presented proposed updates to Eagan’s pavement‑management program and special‑assessment policy, including a new surface treatment option called a rejuvenator and a change to assess curb‑and‑gutter costs as part of improvement projects.
Aaron (public works) explained the city's approach to extending pavement life through a combination of timely mill/overlays and newer surface‑treatment techniques. The rejuvenator is a surface application intended to penetrate pavement and restore oils rather than adding chip rock; staff said neighboring communities have used it for up to about 10 years and the University of Minnesota has research on several products. The city will run side‑by‑side testing this summer in Wilderness Park and include the cost in feasibility reports to enable contractors and the council to evaluate outcomes.
On assessments, staff reminded the council that the city recently moved to include curb‑and‑gutter as an assessable cost, which is estimated to generate roughly $530,000 additional funding for planned mill/overlay projects across the five‑year CIP. Staff estimated the average residential assessment increase at about $60 (commercial/industrial estimates vary by parcel size) and said assessments shown at hearings will be based on estimated final completion costs if the physical rejuvenation work is scheduled the following year.
Council members asked whether rejuvenator testing is proven and how disruptive application is; staff said the treatment can typically be completed in a single day for a typical neighborhood and contractors perform sweeping to reduce tracked material. Staff also said they will be seeking bids in advance to lock pricing for treatments that will be applied the following year, and emphasized the statutory requirement that assessments be tied to measurable increased property value.
What’s next: staff will pilot rejuvenator products this summer, include line items in feasibility reports for projects where rejuvenators are planned, and prepare assessment hearings in the fall based on estimated final costs.
