Stormwater Control Other Point

For more information about this layer please see the GIS Data Catalog. Component Types for Control Other (Point)-Dry Well: Gravel filled holes or structures used for temporary storage and infiltration of stormwater runoff.-Injection Well: A structure that is deeper than it is wide that is designed to infiltrate stormwater runoff.-Full Dispersion: Features a native vegetated flowpath segment of at least 100ft (25ft for sheet flow from a non-native pervious surface) along the flowpath that runoff would follow upon discharge. The flowpath segment must be either onsite or in an offsite tract or easement area reserved for dispersion and should be designated as a “native growth retention area” on the flow control BMP site plan attached to the required declaration of covenant and grant of easement. Full dispersion involves use of splash blocks, rock pads, gravel filled trenches or sheet flow.

——干井（Dry Well）：用于临时储存并下渗雨水径流的碎石填充孔洞或构筑物。
——注入井（Injection Well）：深度大于宽度的构筑物，设计用于下渗雨水径流。
——全分散系统（Full Dispersion）：沿径流排放后流经的流动路径设置至少100英尺的原生植被覆盖流动段，非原生透水路面形成的片状流（sheet flow）则需长度不低于25英尺。该流动段需位于场地内部，或位于场地外预留用于径流分散处理的地块或地役权区域内，且需在附于所需地役权契约与出让声明的径流控制最佳管理措施（BMP）场地平面图中被标注为"native growth retention area"。全分散系统可采用挡水块、石质垫面、碎石填充沟渠或片状流形式。
