Platte to Park Hill Project Phase 1 update

From 9News.com (Cory Reppenhagen):

Denver Public Works refers to that problem area as the Montclair basin. It is the largest basin in Denver at 9.5 square miles, that does not have a path for stormwater to get to the South Platte River.

So they say that stormwater tends to pool in that area, and some of the worst flooding in the city steams from this spot. The solution, according to Denver Public Works, is to build the largest flood protection project that Denver has ever seen.

The Platte to Park Hill Project, or P2P, is extremely progressive in its use of open channels, water quality features, and inclusion of community and recreational assets.

A 9NEWS crew toured the nearly completed first phase of this plan, called the Globeville Landing Outfall Project, which Denver Public Works describes as a giant storm drain.

The centerpiece of this project is a massive pipe that’s actually a 500-yard-long, 12 foot by 15 foot – a concrete box culvert…

This project will protect those historic neighborhoods around the Denver Coliseum, like Elyria, Swansea, Cole, Whittier, Clayton, Skyland, and Five Points.

Denver Public Works said it will not only handle the routine stormwater, that often floods those areas, but also the big 100-year events.

“It’s those storms that are above an inch in an hour. Two inches, three inches in an hour, those are the ones we don’t have a system for, those are the ones that this system is really going to do a good job for us,” said Uhernik.

A thunderstorm that covers all 155 square miles of Denver, with just 1 inch of rain, puts down 2.7 billion gallons of water, which is enough to fill about 67 million bathtubs…

In this new project, the water will flow out of that culvert and into the open, where it will run through a new park and into the South Platte River, just along the west end of the Denver Coliseum parking lot.

It’s a natural path restored.

Denver Public Works says this drain will be ready to take on stormwater by this summer. The new city park will be completed in the spring of 2019.

They plan to build similar drains downstream in the years to come.
