A rain garden decision tree tool to help individuals decide which type of rain garden should be installed at a specific site.
Bioretention creates a good environment for runoff reduction, filtration, biological uptake, and microbial activity, and provides high pollutant removal; bioretention can become an attractive landscaping feature with high amenity value and community acceptance.
Grass channels can provide a modest amount of runoff filtering and volume attenuation within the stormwater conveyance system resulting in the delivery of less runoff and pollutants than a traditional system of curb and gutter, storm drain inlets and pipes.
The objective of this memo is to provide the scientific basis for creating a workable engineering framework for runoff reduction and stormwater treatment practices.
The Impervious Cover Model (ICM) was first proposed in 1994 as a management tool to diagnose the severity of future stream problems in urban subwatersheds.
Stormwater retrofitting will be a major strategy for many localities to achieve nutrient reductions to meet more stringent MS4 stormwater permits and TMDLs.
