This site was considered unusable because the surrounding developments had stormwater running through this site. With the tight constraints and the layout of the proposed building, Rainstore3 was the only solution. In fact, Rainstore3 made the development of this site possible - without RS3, the City of Broomfield would not have allowed construction. The site was also unique for its L-shape plan. The majority of the chamber is on the south side of the building and it forms an “L” with some turning the corner to the west site of the building. The cell stacks six units high - to contain all the stormwater necessary and to be piped out into the city’s above ground stormwater system.

Site plan showing the Rainstore3 system in blue. Notice the slight “L” shape and the cutouts for landscaped islands for trees. The building is represented in gray and the triangular site in pink.
A break in the RS3 cells (foreground) show where the landscaped islands with trees will be after completion.
Workers place the cells as a forklift offloads pallets from the truck.
This photo shows the unique “L” shape of the install. The back ground shows the RS3 cells with geogrid and fabric. The center shows cover material. The foreground shows the “L” going off to the left of the building.
Close-up shot of part of the installation procedure: Geogrid directly on top of the RS3 cells, and filter fabric above that. An additional layer of geogrid (see photo 6) is placed over the entire chamber.
A bobcat pushes cover material (gravel roadbase) over the RS3 chamber. A top layer of geogrid is installed above the entire system and below the cover.
Asphalt for parking covers the entire Rainstore3 system.
