Solution to Stormwater Found
When the developers of the Pebblewood Townhomes in Colorado Springs, Colorado, was designing the complex, they chose to funnel stormwater to a nearby cliff where it would then fall into a storm sewer. Over the past twenty years, that cliff has been renamed ‘Stormwater Canyon’ by the locals, and with good cause. Decades of stormwater runoff has eroded the cliff into a canyon, causing flooding problems for the people downstream, and threatening to collapse the cliff along with the homes it supports.
Under pressure from the affected neighborhoods, the city has approved a $600,000 plan to fix the problem, which stormwater manager Tim Mitros laid out. “There’s a drainage system down below, but there was never a connection from the top to the bottom, so that’s what we’re going to do now. We’re going to make that connection (with a drainage pipe), so that the water doesn’t pick up the dirt and sediment that can erode the side of the cliff.”
Once the pipe is in place, the city plans to clear the storm sewer of excess debris, and repair the damaged cliff. The plan is currently only one-third funded by the city, which hopes the rest will be found in grant money.
