BOISE, Idaho — Crews have removed an old storm drain pipe that caused a trench to fail in a Boise North End street, causing a visible hole about 8-feet deep and 8-feet wide.
The hole is located on Lemp Street between 20th and 21st streets. As of Wednesday, crews are installing a new PVC pipe that is more resistant to corrosion, The Ada County Highway District (ACHD) said. This pipe is expected to be installed by the end of the week and the road will be repaved.
Repairs are estimated to cost around $233,000.
This 'trench' is a storm drain pipe that has been in the ground around 80-100 years -- those years of weather can cause it to fail, causing the ground below to collapse and the asphalt above it to give out, an ACHD worker told KTVB. The Treasure Valley's most recent storm could have washed that supporting soil away, the worker said.
Neighbors who normally place trash cans in the alleyway between 20th and 21st Streets for pickup need to place them Heron Street or West Ridenbaugh while road closures are in place.
