Enchanted Hills Elementary School had been sited near the bottom of a large arroyo in Rio Rancho at the confluence of 5 major tributaries of a 135 acre watershed. Storm flow on several occasions had entered the school and deposited several inches of sediment, closing the school for several days as it was dug out. SSCAFCA designed a detention pond to intercept the storm flow and send the overflow into the City storm drain system through a box drain in the bottom of the pond. Adaptive Terrain Systems shaped slope geometry, inlet and access pads, and shaped the bottom of the pond bottom so that even in violent local storm flow, no sediment makes it into the City storm sewers.
