Project Background

Underground water pipes that are approaching the end of their useful life will be upgraded to maintain critical utility services and avoid disruptive emergency repairs.
The project will also construct curb ramps within the limits of the project to facilitate accessibility in accordance with the Americans with Disabilities Act.
What to Expect During Construction

The utility project will be done in phases, so work will not be happening on your block for the entire project duration. Construction activity on your block will appear to be intermittent. Expect for our crews to finish a portion of work on a block and then return at a later date (sometimes months later) to work on a different aspect of work. There may also be periods of inactivity during the work dates.
Local access for residents will be maintained at all times during work hours, though there may be some slight delay to enter or exit your property/driveway to allow for crews to create a safe path of travel.
