Greetings!
You are invited to attend a new workshop:
Small-Scale Bioretention Installation Training
A practical one and a-half day short course for contractors, landscapers, designers, and DPW/Parks Department Staff
April 11 and 12, 2012
Roger Williams Casino, Providence, RI
Bioretention Facilities are rapidly becoming a mainstream way to control stormwater runoff. They are one of the most versatile new stormwater practices now required under Rhode Island's 2010 Stormwater Manual.
Come to this workshop to learn how bioretention facilities work and how they are sited, designed, installed, and maintained. This one and a-half day workshop will start with a classroom session, include a field reconnaissance of how these practices are chosen and sited, and conclude with an actual installation of a facility. Instructors are from the Horsley Witten Group, authors of the 2010 RI Stormwater Manual.

When:
April 11 (classroom and fieldtrip): 8:00 am - 5:00 pm
April 12 (field installation): 8:00 am - 12:00 pm
Where:
Roger Williams Park Casino
1000 Elmwood Avenue
Providence, RI 02903
Registration:
This training is free but registration is required.

Bioretention Facilities Versus Raingardens
You have heard of a raingarden, but what is bioretention?
Raingardens are small-scale, shallow, vegetative areas designed to intercept, treat, and infiltrate stormwater within native soils. Raingardens manage stormwater runoff from smaller drainage areas such as rooftops, but also from driveways, lawns, roads, and parking lots. Raingardens look like regular perennial gardens except that during a storm, a raingarden fills with water, and the water slowly infiltrates into the ground.
Bioretention areas are typically larger facilities, usually designed with underdrain systems, defined structures for overflow, and a prescribed planting soil mix to promote filtration of stormwater. Like raingardens, bioretention facilities are shallow vegetative areas sized to intercept and treat runoff; but, unlike a raingarden, bioretention may not have any infiltration into native soils. In essence, bioretention is a more complex system relying primarily on filtration to treat stormwater runoff.

This workshop is sponsored by the U.S. Environmental Protection Agency, Region 1, in partnership with the City of Providence, Groundwork Providence and the University of Rhode Island Cooperative Extension, RINEMO.
