Overlook Sewer Replacement Project

  •  Construction Update

April 9, 2014

Environmental Services is replacing or repairing about 17,000 feet of public sewer pipes in the Overlook neighborhood that are between 60 and 90 years old and in poor condition. The city installed many of these sewers before 1920. The project includes constructing about 9,100 feet of 6-inch sewer branch pipes that will connect homes and businesses to the new public sewer pipes. Replacing and repairing these sewers will protect the public and the environment by reducing the possibility of costly breaks, leaks, blockages and sewage releases to homes, businesses and streets.

DEVELOPMENTS OF NOTEClick to view a larger map

Killingsworth Street (Greeley to Interstate)

  • Beginning Monday, April 21, N Killingsworth Street will be closed to eastbound traffic between N Greeley and N Boston Avenues for final paving.  Local through access will be provided for one westbound traffic lane only.
  • The traffic controls will be in effect all hours and all days for approximately one week with flaggers controlling local traffic as needed. Please expect delays and use alternate routes when possible. 
  • On-street parking will not be available near the work zone.  Business patrons and residents who normally park on Killingsworth (Greeley to Boston) must park along side streets during this process. 
  • Drivers and bike riders using Killingsworth should observe traffic control signs, and avoid work zones where possible.

Wygant Street (Gay to west end)  

  • The aging concrete in combination with challenging soils have made the roadway on Wygant Street particularly susceptible to construction damage. 
  • To address this issue, the construction team has been working with the Bureau of Transportation to develop an alternative concrete restoration plan that will resurface the roadway and repair curbs, sidewalks, and driveways disturbed by construction.
  • Crews will prep Wygant Street for resurfacing as soon as Monday, April 21.  This work is expected to take up to three weeks. 
  • Residents living on Boston, Blandena, and Wygant west of Gay will receive a flyer with additional details.


  • Several residents and property owners have inquired about the restoration work yet to be done on some sidewalks, curbs, driveway aprons, planting strips and other areas affected by sewer construction. All locations that have been emailed or called in to Public Involvement have been placed on a list and shared with the construction team.
  • As construction crews finish main pipe work and focus on paving and restoration, wet spring weather will likely require changes to the construction schedule. The email update you receive is a reflection of what the contractor intends to complete barring unforeseen circumstances.


Please remember that businesses within construction zones are OPEN. If you are traveling to a business within the construction zone, you may see orange signs and barricades reading ROAD CLOSED to Thru Traffic – Local Access Only. The signs are intended to reduce overall traffic going through the area while construction is underway, but everyone living in or conducting business within the construction zone will be allowed access.


Below is the estimated Overlook sewer construction schedule for the rest of this week and the next three weeks. Construction will move from one site to another as work on each segment is completed. Please be aware that this schedule is subject to change due to a variety of factors, including conditions underground, weather, traffic impacts, subcontractor schedules and availability of materials.

Week of April 21

  • Killingsworth Street (Greeley to Delaware) – asphalt preparation and restoration
  • Sumner Street (at Adidas campus) – concrete preparation and restoration
  • Wygant Street (Gay to west end) – concrete preparation and restoration

Week of April 28

  • Killingsworth Street (Concord to Interstate) – asphalt preparation and restoration
  • Wygant Street (Gay to west end) – concrete preparation and restoration

What to Expect During Construction

  • Typical work hours are 7:00 a.m. to 6:00 p.m. Monday through Friday, but the contractor may schedule work during the same hours on Saturdays.
  • Construction creates noise, vibration and dust and disrupts normal neighborhood activity.
  • Traffic control signs are in place. The contractor maintains local access, but you should expect delays.
  • On-street parking in or near the work area is prohibited during construction hours. Please plan to move your vehicle by 7:00 a.m.
  • Equipment and materials may be stored on nearby streets overnight.
  • There may be periods of inactivity between construction phases.
  • A city inspector is on-site during work hours and may be able to assist you with construction concerns. Inspectors typically wear a safety vest and hard hat.
  • Please stay clear of all construction activities. Please keep your children from harm and instruct them to stay clear of all construction activities. We also appreciate your keeping pets and vehicles out of the construction areas.
