To improve the stormwater characteristics of the site, a “green” alley is installed using Ecoraster-brand geotextile panels. With an underlayment of compacted gravel and soil, the Ecoraster sheets snap together in a matrix. The open cells are then filled with additional topsoil and grass seed and are watered. The completed alley allows stormwater infiltration, captures pollutants, and will create additional green space for owners.
