Stormwater Stars workshops provide ideas on how to manage rain that falls around your home, school, workplace, or place of worship. You’ll receive an overview of the best ways to handle stormwater issues, and get plenty of hands-on practice in restoring soils, naturescaping with native plants, creating pervious pathways, and more. If you live, work, or play on a site that has excessive mud, pooling water, or compacted soil, then these workshops are for you! 


Pre-registration is required for these events. Sign up for fall workshops here.

Stormwater Stars workshops lead participants in hands-on planning and installation of yard-scale stormwater management techniques, including soil amendments, permeable walkways, pavement removal, lawn reduction/replacement, native landscaping, and biodegradable erosion control to reduce the volume of stormwater runoff and sediment pollution generated by their property.

These practices reduce stream bank erosion, pollution, habitat degradation, and flooding in local streams while creating backyard habitat and reducing the need for harmful lawn and garden chemicals. Stormwater Stars practices may also help with minor drainage issues such as damp lawns, low-lying soggy areas and surface erosion. 

Workshops and home visits conducted through this program DO NOT include recommendations for drainage piping or plumbing, basement flooding, foundation problems or foundation drains, French drains, retaining walls, landslide prevention, mitigation of high groundwater, or the capture and infiltration of runoff.  We recommend that property owners consult a qualified licensed engineer to address such issues.
