Projects Under Construction


See the bottom of the page for other important Non-Town related construction information.

  • 2018 Paving Program (updated 9/20/18)  Crews are paving Suzanne, Millbrook and Westwood today, 9/20. Crews will begin work on Westwood at 7am and proceed according to the map. Work should wrap up at 6pm. The roads will be closed and residents are advised to park offsite if access is required to the neighborhood during the day.  Crews and detail officers will navigate school buses into the neighborhood to pick up and drop off students. Please note that driveway aprons on roads paved recently will be paved in the next couple of weeks.  You may notice a gap where it looks like the drive does not meet current pavement on the street.  When the aprons are paved they will match the grade of the street.  In some cases, the aprons will have a raised surface to keep the storm water in the street from running to the home if it is lower.  Inpsectors in the field watch for this and it is field corrected during the work.  Thank you for your understanding and patience.
