Cornell Cooperative Extension Orange County Stormwater Planter

An existing raised planting bed running along the front of the building was overgrown and in need of renovation, so it presented an opportunity to retrofit the planting bed to a stormwater planter. Existing plants were removed, an underdrain was installed, select soil was added, and appropriate vegetation was planted.
