A stormwater planter assembly featuring an eighteen-inch growing medium over a six-inch layer of two-inch washed drain rock lined with a thirty-mil EPDM waterproof liner. A four-inch perforated pipe runs through the drain rock layer, connecting to an eight-inch storm pipe with a pipe boot. An eight-inch overflow riser inlet with a Nyloplast drain basin and eight-inch dome grate provides a twelve-inch storage depth and a two-inch freeboard. The assembly is bounded by concrete curb planter walls with a bottom width that varies per plan.
