This Saturday, July 9, board the sailboat Northwind for a free two-hour (9:00-11:00 a.m.) tour of the Delaware River. Learn about the river's history and ecology; the tour will also focus on Washington Avenue Green, the recently constructed public park along the Delaware. The photo above depicts a rain garden in the park that collects stormwater runoff from the nearby parking lot. Other ecologically friendly features of Washington Avenue Green include floating wetlands that provide habitat for aquatic life and depaved portions of the parking lot that allow stormwater to infiltrate the soil below.

RSVP by tomorrow, July 6 by sending an email to DelRiverEvent@gmail.com. Again, the tour is free but space is limited; all sailors must be at least 16 years old. Visit the event's Facebook page.
