Reviewing engineers and public works staff are invited to a Q&A with Larry Coffman, nationally recognized expert on low impact development technology for water resources and ecosystem restoration.

This is your opportunity to ask your most challenging questions about stormwater management practices using:

rain gardens and bioswales
narrow roadways
alternative turnarounds in lieu of large, paved cul-de-sacs
pervious pavement
other types of bioretention and biofiltration mechanisms
and more!

Hear and discuss with your peers answers to questions such as:

How have other jurisdictions successfully implemented low impact development practices, both for developers and for public projects?
What is their success rate for keeping the facilities maintained?
How can we rely on infiltration practices such as swales and pervious pavement in areas with clay soils?
What data supports the premise that low impact development facilities are useful at both pollutant removal and amount of runoff infiltrated?

Larry Coffman is the pioneer of the innovative bioretention or "rain garden" stormwater management practice and nationally-recognized expert on bioretention and low impact development design guidelines for new and existing commercial and residential developments.

Nature in Neighborhood seminars are brought to you by Metro in partnership with Filterra Bioretention Systems. Filterra sponsors low impact development educational events and in no way promotes its products directly. This event is in no way an endorsement of Filterra Bioretention systems.
