Watershed board approves tree removal and pipe replacement to clear obstructed tile on Cyclone near Kirkland Brick Road
Summary
Watershed staff said a section of tile in the Sarah Taylor watershed on Cyclone is crushed and full of roots after an incorrect installation with 10-inch tubing; the board authorized staff to notify the owner, remove trees in the right of way and install solid double-wall pipe to restore drainage.
The Watershed Board authorized staff to notify a landowner, remove trees from the right of way and replace an obstructed drainage tile on Cyclone that is preventing water from leaving the north side of Kirkland Brick Road.
Watershed staff said the tile section was apparently rebuilt several years ago using 10-inch tubing that was installed incorrectly, and that part of the installation was crushed during installation and has since filled with tree roots. “This pipe was apparently rebuilt … several years ago … it was done with tubing, 10 inch tubing, and it was installed incorrectly,” Watershed staff said. “So part of it was crushed during installation. Now it's full of tree roots.”
The obstruction has caused complaints about poor drainage and standing water on the north side of Kirkland Brick Road, staff said. The crew identified maple and pine trees growing over the pipe; staff said they will reclaim part of the right of way and remove trees as needed to permit installation of new pipe. “We're going to be taking out some trees and reclaim part of our right of way, and we'll put in new double wall pipe, eliminate those roots,” Watershed staff said.
Staff said they were weighing whether to use perforated or solid pipe. Staff indicated a tendency to choose perforated pipe to allow subsurface infiltration if trees regrow, but board members voiced support for solid pipe. “I would tend to put in perforated, but I kinda wanted the board to give me a little guidance there,” Watershed staff said. Board members indicated support for solid pipe.
In the course of the investigation staff discovered the pipe does not extend where maps indicate; it ends at a riser. Staff traced an undocumented connection installed in the 1980s by a contractor named Herb Jackson that runs along a railroad bed to the Cyclone elevator. “At some point in the eighties, contractor named Herb Jackson … ran a pipe along that railroad bed to the elevator. So it's not on any of our maps, but we have verified that,” Watershed staff said. The elevator has not complained, staff added, but a farmer on the east side of County Road 400 has complained about water not draining.
The board moved and seconded staff’s proposal to notify the owner and proceed with removing trees and replacing the obstructed pipe; the motion carried. Staff said they will notify the landowner, remove trees in the right of way as authorized, and install new double-wall pipe. Staff noted some follow-up inspection will be possible once water is removed and the north side can be accessed.
Board action: motion to authorize staff to notify the owner, remove trees from the right of way and replace the obstructed tile with double-wall pipe — moved, seconded, motion carried.
