Stormwater Control Other Polygon

For more information about this layer please see the GIS Data Catalog. Other Control (Polygon) Component Types---Bioretention Cell: Shallow depressions with a designed planting soil mix and a variety of plant material, including trees, shrubs, grasses, and/or other herbaceous plants. Bioretention cells may or may not have an under-drain and are not designed as a conveyance system.---Bioretention Planter: Feature a designed soil mix and a variety of plant material including trees, shrubs, grasses, and/or other herbaceous plants within a vertical walled container usually constructed from formed concrete, but could include other materials. Planter boxes are completely impervious and include a bottom (must include an under-drain). ---Permeable Pavement (Vegetated): Vegetated pavement that allows water to infiltrate to the ground.---Permeable Pavement (Non-Vegetated): Non-vegetated pavement that allows water to infiltrate to the ground. ---Rain Garden: Shallow depressions with a designed planting soil mix and a variety of plant material, including trees, shrubs, grasses, and/or other herbaceous plants.

其他（面状）控制组件类型---生物滞留池（Bioretention Cell）：配备定制种植土壤混合料与多种植物材料（包括乔木、灌木、草本植物及/或其他草本类植物）的浅洼地。生物滞留池可设置或不设置地下排水设施，且并非作为输水系统进行设计。
---生物滞留种植箱（Bioretention Planter）：通常由预制混凝土构筑的立式壁容器内搭载定制土壤混合料与多种植物材料（包括乔木、灌木、草本植物及/或其他草本类植物）的设施；种植箱完全不透水且带有底板（必须设置地下排水设施）。
---植被型透水铺装（Permeable Pavement (Vegetated)）：允许雨水下渗至地下的植被覆盖路面。
---非植被型透水铺装（Permeable Pavement (Non-Vegetated)）：允许雨水下渗至地下的无植被覆盖路面。
---雨水花园（Rain Garden）：配备定制种植土壤混合料与多种植物材料（包括乔木、灌木、草本植物及/或其他草本类植物）的浅洼地。
