What's Happening Now

Over the next several months and throughout the year, you may notice work crews in your neighborhood marking the locations of utilities, storm water sumps, water lines and other underground utilities with temporary paint markings. Crews will also be gathering information about soil and pavement conditions and identifying issues that may affect construction. These activities typically occur over time, rather than all at once.

Survey crews will also be measuring first-floor elevations and documenting homes with basements. While they will work primarily in the public right-of-way using non-invasive methods, they will need to take readings from on property at times. Crew members will knock on the door and let residents know of their presence, and will not need to enter homes or other buildings. Crew members will be wearing safety vests, and will have city identification. This analysis will allow engineers to design a sewer extension that will meet the depth requirements for gravity flow from each house.
