City dump trucks will be plentiful in the Garden of the Gods
area this week as city streets crews haul off 1,500 cubic yards of sediment that washed off the Waldo Canyon Fire
burn scar last fall during heavy rains into a basin on the north end of Garden of the Gods Park.
The city expects the sediment to equate to about 150 truckloads over the next couple of weeks. The sediment is being hauled to the Flying W Ranch, which is planning to construct a parking lot.
“This is probably saving the city a ton of money,” Tim Mitros
, development review and stormwater manager. “Otherwise, our haul sites are down south off Las Vegas Street.”
After the sediment is removed, the city plans to contract with the Coalition for the Upper South Platte
to build a sedimentation facility that will be cleaned periodically over the next 10 years, if needed. The material consists of small sticks and rocks, sand and branches, city spokeswoman Kim Melchor
The project, which will cost $350,000
, is considered an emergency repair project, funded by National Resource Conservation Service Emergency Watershed Protection monies (75 percent), the Colorado State Office of Emergency Management (12.5 percent) and the city (12.5 percent).
“It is not a detention pond,” Melchor notes, but rather a catch basin for debris.
"We have not done this before, where we’ve designed a sedimentation basin just to collect sediment," Mitros says. "I thought it was interesting, the flooding that’s going on in L.A. They showed some sedimentation basins they had done because of the fires, and they worked."
