Overgrown invasive trees and trash that once dominated an 18-acre parcel near Pikes Peak Avenue and South Academy Boulevard have largely been cleared away in recent weeks as Colorado Springs city crews prepare to put in new wetlands.
The lot looks more like a construction site following several weeks of work by crews who removed 200 tons of trash, but this is just a first step in a project expected to take about two years and cost several million dollars to restore the site to a more natural state. The work will slow down stormwater and help improve water quality before it flows downstream, said Richard Mulledy, Stormwater Enterprise manager.
The city will need to change the topography of the property, in part because Spring Creek and a tributary have cut deep ravines across the lot, and plant new native vegetation, including willows and cottonwoods for new wetlands, he said. The creeks themselves could see new boulders and structures to help slow the water down, he said.
“I think it’s a gem. … It’s unpolished, it’s pretty raw, but it has amazing potential,” Mulledy said.
In southeastern Colorado Springs, few large undevelopable properties remain, and once restored the parcel could provide a welcoming open space for the neighborhood, he said. The Stormwater Enterprise is working with the parks department on potential trail connections to the property, he said.
The wetlands could improve stormwater quality by removing nutrients from the water, such as nitrogen, that flow in from yard fertilizers and contribute to algae blooms that can kill off wildlife. Wetland plants, such as cattails and bulrushes, can also remove heavy metal particulates from the water and keep them from flowing downstream, he said.
“It’s hard to treat stormwater. … so really our best tool is wetlands and wetland species,” Mulledy said.
The project is one of hundreds the city has done over the last five years to improve stormwater quality after years of not properly funding infrastructure. The neglect of the stormwater system led to the city recently agreeing to spend $45 million on projects to settle a lawsuit brought by the Environmental Protection Agency, Pueblo County and the Lower Arkansas Valley Water Conservancy District.
The Colorado Springs City Council approved an increase to monthly stormwater fees set to take effect in July to help cover the cost of those projects. Residential fees will go up from $7 per month to $8 per month over three years.
The project near Pikes Peak Avenue could see some of that funding as it takes shape in the coming years. The recent work to clean up the property and remove trees cost about $100,000 and the full restoration of wetlands could take $2 to $3 million, Mulledy said.
New vegetation could start going in at the end of the summer or next spring, but in the mean time city staff and volunteers will be able to keep the area cleaner because they have better access to the property, Mulledy said. Previously, the dense Russian olive and Siberian elm trees prevented equipment from accessing the property, he said. The trees were also water hogs and needed to be removed.
He expects vegetation will regenerate quickly across the property and potentially provide natural habitat for birds and other wildlife.
