McAlpine Greenway near Sardis Closing, Providence Road to be closed at McAlpine Creek

McAlpine Creek Relief Sewer Project (Phases one, two, and three) is a $53 million investment to enhance sanitary sewer system performance, provide increased sewer capacity for present and future needs, and protect the water quality in McAlpine Creek. Phase three (Colony Road to Independence Boulevard) is under construction. Pipe sizes in phase three vary from 66-inches in diameter to 36-inches and as deep as 20 feet underground. Two upcoming activities will impact citizens that use Upper McAlpine Creek Greenway, James Boyce Park, or McAlpine Creek Park and/or drive on Providence Road.

Sections of Greenway Closed for Construction

The City’s contractor is starting sewer pipe installation under Upper McAlpine Creek Greenway near Sardis Road on May 27. The greenway will be closed between Sardis Road and Monroe Road, although some areas may be accessible until crews begin digging. Construction vehicles may access greenway site from Sardis Road and Monroe Road. Mecklenburg County Park and Recreation (MCPR) and Charlotte-Mecklenburg Utility Department (CMUD) are working closely to reduce the impact of the sewer project on adjacent public facilities such as Boyce Park and McAlpine Creek Park, especially the fall 5K race season. The 5K trail events in McAlpine Creek Park will not be interrupted between August 1 and December 15 of any year. Both James Boyce Park and McAlpine Creek Park will be open and accessible, although some areas may be limited during construction. CMUD and MCPR installed signs in parks and entrances to alert citizens about sewer project and greenway closure. Click here to view pdf of greenway map showing construction activity.

   What causes sewer spills? 

   Kitchen leftovers (oil, grease) and tree roots cause more than
   70% of sewer spills. Prevent costly repairs by tossing leftover
   food in the trash.


  • Construction Activity Map

  • February 7, 2011 public meeting Construction Presentation and Park & Recreation Notes
  • The sewer pipe is 66-inches in diameter at Colony Road, 54-inches in diameter at Sardis Road, and 36-inches at Independence Boulevard (Hwy 74).
  • Crews will tunnel under roads that go over McAlpine Creek.
  • Crews began near Colony Road and work their way upstream.

Construction Activities to Expect

Surveying – Crews may enter easements to mark trees for protection or removal. Orange fencing will be placed to mark existing gas lines. Erosion control fences may also be put in place.

Clearing – Trees, shrubs, bushes and other vegetation within the construction easement area will be removed. Tree stumps will be removed and holes filled. Some debris will be transported off-site and some shredded into mulch.

Blasting – Crews may encounter rock while installing pipe along the route. If rock cannot be excavated by traditional methods, these sections of rock will need to be broken by blasting with small amounts of dynamite. Controlled blasting occurs underground in holes drilled into the rock. Blasting is a standard construction procedure and will be monitored with seismographs to help minimize earth vibration levels.

Safety Precautions Around Construction Zones

Throughout construction, the safety of residents along the route is of the utmost importance.
To limit truck traffic in the surrounding area, trucks delivering pipe and materials to crews will be allowed to access the sewer route only from designated entry points.
Regular work hours, except tunneling, will be limited to a 10-hour period between 7 a.m. (sunrise) and 7 p.m. (sunset) Monday-Friday, excluding Charlotte holidays. Crews will follow the City of Charlotte noise ordinance.

Why is this project necessary?
Improvements will increase sanitary sewer capacity to meet current and future needs. These pipes will reduce the risk of sewer overflows and protect water quality in McAlpine Creek.

Will my water or sewer services be disrupted during construction?
Disruptions to water and/or sewer services are not expected. If a service interruption becomes necessary, affected customers will be notified in advance.

How will I know when construction is nearing my property?
Charlotte-Mecklenburg Utility Department will reach residents and property owners through letters, email updates via website "notify me," and public meetings. If you have general questions about our engineering projects, email us or call 704-399-2221.

Will traffic be impacted?
The existing sewer lines are built along McAlpine Creek so the majority of the work will not impact roadways. When the pipe improvements must cross a street, engineers have planned for many of the major thoroughfares to be tunneled so traffic is not disrupted.

How will area be restored?
After the sewer line is activated, contractors will complete final restoration along the route to repair areas disturbed during activation. This includes:

  • Grading the soil
  • Reseeding grass / applying straw mulch
  • Installing permanent fencing that was removed for construction
  • Restoring creek banks
