Piedmont-Woodlawn-King Sewer Repair Project

JULY 2014

Environmental Services is designing a project to repair or replace 29,000 feet of deteriorating sewer pipes at several locations in the Piedmont, Woodlawn and King neighborhoods. This project will reduce the risks of street flooding and sewage releases to homes, businesses and streets. Construction is scheduled to begin in winter 2015. 

Soil Sampling Starts in August 2014

For approximately three months beginning in August 2014, work crews will be drilling holes in street pavement and taking soil samples at several locations to help the design engineers understand conditions that construction crews may encounter. What the engineers learn from analysis of soil, rock and pavement samples will help them determine construction methods. 

Soil sampling will occur Monday through Wednesday between 7:00 a.m. and 6:00 p.m. Crews will work at eight to ten locations a day beginning at the north end of the project area and moving south (map forthcoming). The holes will be a few inches in diameter and will be filled immediately after the drilling is completed. 

This work may require temporary lane restrictions and on-street parking closures. There may be brief periods of noise, dust and mild vibration during drilling. Work at each location will last approximately one hour.  

Locating and Marking Underground Utilities

All sewer design and construction projects depend on advance surveys of construction areas. A few weeks before soil sampling starts, crews will also be in the neighborhood to locate and mark underground utilities by painting stripes on surface streets and sidewalks or placing colored flags in landscaped areas. Each color indicates what is buried below. The color code is as follows:

  • White = proposed excavation
  • Pink = temporary survey markings
  • Red = electric power lines, cables, conduit and lighting cables
  • Yellow = gas, oil, steam, petroleum or gaseous materials
  • Blue = potable water
  • Purple = reclaimed water, irrigation and slurry lines
  • Green = sewer and drain lines
