As part of infrastructure improvements, storm- water planters installed on the West Capitol Avenue streetscape in West Sacramento, California were designed to treat storm runoff (see accompanying dia- gram). Each stormwater planter has two openings in the curb that allow runoff to be directed from the street into the planter.
The soil in the planter includes a bioretention planting mix, coarse sand, pea gravel, and washed stone above a perforated pipe and geotextile filter fabric. The mix allows the runoff to be cleaned before discharging through the perforated pipe and into the existing storm drain system to con- tinue downstream.
