City's Flood Mitigation Efforts in Full Swing

In the wake of the Waldo Canyon fire, debris and mud coming off the burn scar during flash flooding has the potential to be a major problem, but the city of Colorado Springs is working on a plan to mitigate that risk.

The city says during last September's flooding, five debris catchment basins on the Flying W Ranch kept 60,000 cubic yards of sediment from entering the city's storm water system.

The problem is, those catchments were completely filled. Now the city is working to build a new pond designed to allow crews to remove the sediment after each storm. The city says it will help protect the channel downstream.

The project is expected to cost about $200,000.

The city is also doing mitigation projects in other places.

A spillway and a debris screen are being installed near the pond at the in Mountain Shadows. A flood wall is also being installed to protect the school.

That project is expected to cost at total of $70,000 by three grants from the Denver Foundation.

City crews are also removing about 600 truck loads of debris from Garden of the Gods Park.

After that is done, the city says a large, cleanable basin will be built in Camp Creek at the north end of the park to collect sediment from the burn scar. It will be the city streets division's responsibility to clean the basin.

The project is expected to be completed in May and will cost about $350,000.

Seventy-five percent of the cost is being covered by funds from the National Resource Conservation Service Emergency Watershed Protection. The remaining 25% will be split between The Colorado State Office of Emergency Management and the city of Colorado Springs.

The public will have a chance to weigh in on some future mitigation projects. One of those projects is to improve Camp Creek drainage. There will be an open house April 29 at 7:30 p.m. in the cafeteria at Coronado High School located at 1590 W. Fillmore St.

$3.675 Million has been allocated to design the Camp Creek channel.

The city also maintains debris flow nets in Queen's Canyon above the Glen Eyrie Conference Center. The nets were installed in 2012 and protect areas like Garden of the Gods and Rockledge Ranch. It also helps keep debris out of the 31st Street channel.

On 8th Street and Cheyenne Blvd., 1,000 feet of pipe that collapsed during the flooding is being replaced. The project is expected to be completed in early June.

That project will cost about $750,000. About one third of the cost is being covered by FEMA.

On 31st street, the drainage tunnel located in the median from West Bijou Street and Echo Lane to Chambers Way is also being repaired.

Crews will be resurfacing areas of the channel where the concrete is damaged because of last summer's flash flooding and debris from the burn scar. $250,000 has been allocated for the project.

The repairs are being made to keep the channel functional until planning, permits and funding are in place to completely reconstruct it.

Repairs are also being made along Cheyenne Creek. Crews will restore the bank in areas that were damaged. Those areas are east of Stratton along Scott Street and along the creek at Mayhurst Ave.

The repairs are expected to start in May and be completed by July 1st.

They are expected to cost about $170,860. Seventy-five percent of the cost will be covered by funds from the National Resource Conservation Service Emergency Watershed Protection. The remaining 25% will be split between the Colorado State Office of Emergency Management and the city of Colorado Springs.
