Comments:
Downspouts drain into an infiltration planter box rather than to the street. Stormwater runoff is temporarily stored above the soil then slowly filters down through the planter into existing soils. By providing 2-3 feet of absorptive soils and plants above the existing grade, this is a good choice for areas with poor drainage.
