Pipes (2)

Pipes, wrapped in a filter fabric, are laid in sand below a bed of shredded tire chips (substituting for stone aggregate), sand, engineered topsoil, and plantings. These pipes are connected by a sump manhole structure fitted with a baffle system developed by the Saint Anthony Falls Laboratory (SAFL) at the University of Minnesota to keep sediment out of downstream water bodies. This is the first time a SAFL baffle was incorporated into a Next Generation stormwater drainage system, a first in the nation!
