runoff reduction

A rain garden decision tree tool to help individuals decide which type of rain garden should be installed at a specific site.

The Blue Flag Iris performed the best of all of the plant species at removing selected pesticides in addition to being a very aesthetically pleasing plant.

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.

Infiltration practices use temporary surface or underground storage to allow incoming stormwater runoff to exfiltrate into underlying soils, allowing for a very high runoff volume reduction capability.

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.

Stormwater in the city is very different than in a suburban county. Webcast covers why redevelopment is difficult, but important.
