A retention basin, sometimes called a retention pond, wet detention basin, or storm water management pond (SWMP), is an artificial pond with vegetation around the perimeter and a permanent pool of water in its design.
This basin type differs from a retention basin, also known as a "wet pond," which includes a permanent pool of water. [ 7 ] [ 8 ] [ 9 ] While basic detention ponds are typically designed to empty within 6 to 12 hours after a storm, extended detention (ED) dry basins improve the basic detention design by lengthening the storage time, for example ...
A stormwater detention vault is an underground structure designed to manage excess stormwater runoff on a developed site, often in an urban setting. This type of best management practice may be selected when there is insufficient space on the site to infiltrate the runoff or build a surface facility such as a detention basin or retention basin. [1]
It is distinguished from a detention basin, sometimes called a dry pond, which is designed to discharge to a downstream water body (although it may incidentally infiltrate some of its volume to groundwater); and from a retention basin, which is designed to include a permanent pool of water.
Retention basins are used to manage stormwater runoff to prevent flooding and downstream erosion, and improve water quality in an adjacent river, stream, lake or bay. Detention basins are similar but are "dry ponds" designed to temporarily hold runoff as a flood control measure.
This is likely due to eminent domain laws, which allow the state government to take property for public use—in Sturgon's case, for a retention pond. Now, the family is coming to terms with leaving.
Sediment basin installed on a construction site. A sediment basin is a temporary pond built on a construction site to capture eroded or disturbed soil that is washed off during rain storms, and protect the water quality of a nearby stream, river, lake, or bay.
In the plan, the Ala Wai Golf Course would serve as a floodwater detention basin with an earthen berm built around the course 6 feet to 9 feet tall.
