Woodlawn-King Soil Sampling
Environmental Services is designing three large-scale sewer projects in North and Northeast Portland neighborhoods to replace or repair approximately 53,300 feet of public sewer pipes that are on average 90 years old and failing due to age. This is the equivalent of 10 miles of sewer pipes. The three adjacent project areas will include construction in Piedmont, Humboldt, Woodlawn and King neighborhoods plus a few blocks in Overlook.
In the Woodlawn and King neighborhoods, the work will include repairing about 29,000 feet of sewer pipes. The sewer repairs will enhance livability by improving sewer and stormwater infrastructure, increasing sewer capacity, and reducing the risks of street flooding and sewage releases to homes, businesses and streets. Construction in Woodlawn-King will begin in 2016.
For approximately two to three months, 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.
WHAT TO EXPECT DURING SOIL SAMPLING
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 (everything north of Rosa Parks Way) and moving south (see map at http://www.portlandoregon.gov/bes/article/489185). 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.
OTHER WORK IN THE AREA
For approximately the next two to three months, work crews will be conducting soil sampling and survey work at several locations in adjacent neighborhoods as well, including Humboldt, Piedmont, and a few blocks in Overlook.
Trucks will also be in Woodlawn-King and adjacent neighborhoods using video equipment to inspect the interior of public sewer pipes. This will involve lowering equipment into a manhole and directing a camera through the sewer pipe. Engineers will use this information to determine if pipes need to be replaced or repaired.
FOR MORE INFORMATION
Contact Rhetta Drennan at 503-823-6006. Before and during construction, we will be sending regular email updates to keep you posted about the schedule, construction activities, possible traffic detours and delays, parking restrictions and other impacts. We encourage you to sign up now to be added to the project's email update list. Send an email to Rhetta.Drennan@portlandoregong.gov with “Woodlawn-King” in the subject line to receive project updates by email.

Working for clean rivers
Over one-third of Portland's 2,500 miles of sewer pipes are more than 80 years old. Projects to replace or repair aging sewers are important for protecting water quality, public health and the environment. Learn more at www.portlandoregon.gov/bes.
