Environmental Services is designing three large-scale sewer projects in North and Northeast Portland neighborhoods to replace or repair approximately 91,000 feet of public sewer pipes that are on average 90 years old and failing due to age. This is the equivalent of over 17 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 61,000 feet (11 miles) 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 summer 2016 and take about a year and a half to complete.
Proposed Pipe Work Locations
The map below shows the proposed pipe replacement and repair locations. It is too early in the design process to know what construction methods will be used where.
What's Happening Now in Woodlawn-King?
For approximately one week in August 2015, crews will drill holes in streets and alleys and take soil samples at several locations to help engineers better understand underground conditions. Analysis of soil, rock and pavement samples will help identify which construction methods to use.
Soil sampling will occur Monday through Friday between 7:00 a.m. and 6:00 p.m. at locations indicated on the map above. Drilled 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 generally lasts less than one hour.
Prior to drilling, crews will mark underground utilities by painting stripes on streets and sidewalks or placing colored flags in landscaped areas. Each color indicates what is buried below.
Trucks have also been in Woodlawn-King and adjacent neighborhoods using video equipment to inspect the interior of public sewer pipes. This involves lowering equipment into a manhole and directing a robotic camera through the sewer pipe. Engineers are using this information to determine if pipes need to be replaced or repaired.
