A team of water engineers and artists has presented the final design to solve Nine Mile Run's stormwater run-off problems. More than two years in the making, it calls for a $2.5 million water detention system that combines art elements and environmental education in a public park.

About 30 people turned out today to watch a presentation of the problem and a computer simulation of the solution at the community center in Summerset at Frick Park.

The Watershed Association has to raise the money to turn what is now a dead-end trolley spur off Braddock Avenue in Swissvale into a system that would catch and detain stormwater run-off for the public to marvel over from a platform above.

That spur now ends at the start of Frick Park's Braddock Trail, which is fenced off in front of what used to be the Center for Creative Play. The fence would be the new Regent Square park entrance, part of a long public plaza that would bring water up into the design of artistic features, such as a canal of water running down public steps.
