Stone Inlet Filter

A technical diagram of a stone inlet filter used for stormwater management. At the top, there is a plan view labeled “PLAN,” showing an arrangement of circular elements representing stone filter material. Four arrows pointing outward are marked as “SLOPE,” indicating the sloping nature of the installation. Beneath the plan view, a cross-sectional diagram labeled “SECTION A-A” illustrates the structure in detail. The section shows a series of layers, starting with stone filter material at the surface, above a “GRATE WRAPPED IN BURLAP” and an “INLET OR CATCH BASIN.” The stone filter material is indicated to have a minimum height of six inches and a width of six feet. Various labels point to different components for clarity. The diagram emphasizes sediment protection for storm structures.
