Research on erosion control and prevention

We have been experimenting with utilizing grasses and perennials in the place of concrete swales as a form of erosion control and bioswale method. This is particularly of importance on sites with a limited budget and a history of flooding, as was the case at the Cohoes Housing Authority in Upstate New York. Included is a series of recommendations that we collected during 3 different field visits to the site.

Plant Selection + Composition Intent

– combination of grasses and a few hardy perennials
– aim is to intercept rainfall before it hits the ground
– slow down runoff
– increase infiltration
– keep soil in place
– reduce sediment and pollutants in runoff
– create wildlife habitat and beauty

General Maintenance + Upkeep Grasses

– grass should grow approx.. 6" - 12" and spread 24" - 36"
– grasses should be cut back to clumps in the ground in late winter to early spring

General Maintenance + Upkeep Perennials

– extremely low maintenance, echinacea will freely self-seed
– tolerant of drought, heat, humidity, poor soil
