Developments of Note

Cured-in-place pipe lining is continuing in various locations throughout the project. Our contractor is now beginning the larger diameter cured in place pipe lining, which requires a longer cure time. This work will last into the evening hours and some to the early morning. You will receive a notice on your door with the date and hours of the operation for your area. Please limit your water usage during the process. Flushing and showers is fine, but do not use your washer, dishwasher or bathtub.

Construction Schedule

The maps below show the  anticipated construction schedule for the next three weeks. Work in each area will take a few weeks to complete and there will be periods of inactivity between construction phases.

The contractor will apply temporary pavement after completing pipe installation in all work areas. Final paving and restoration will take place at a later time as weather allows.

Areas on the map marked in gray are currently not on the schedule or are incomplete at this time.

The construction schedule is subject to change due to conditions underground, weather, traffic impacts, subcontractor schedules and availability of materials.

Through October 28
