Title
88th Avenue Corrugated Metal Pipe (CMP) Storm Sewer Replacement - ITB 24-060
History
On Friday, August 2, 2024, Public Works crews responded to a sinkhole that formed under the sidewalk of the creek crossing at 13402 88th Avenue. The initial investigation showed that the sinkhole formed over the corrugated metal pipe (CMP) that allows the creek to flow under 88th Avenue at that location. Further investigation revealed the CMP is failing. There are large holes in the pipes, and the bottom of the pipes are missing, which is causing water to erode the ground on the outside, contributing to the sinkholes.
The sink hole took one (1) full load of a one (1) ton dump truck to fill in, to make it safe so a pedestrian doesn’t fall in and get hurt. Trying to patch the pipe would be a very temporary solution, while replacement would be a permanent, albeit it costly, solution. The site has continued to settle and loses dirt and stone under the sidewalk with every rain event, and a permanent repair needs to be made.
