From event description:

The Department of Historic Resources’ Underwater Archaeology Program is leading presentations about the history of the James River and its impacts on the City of Richmond. We hope you’ll join us for these talks, and then go on guided walks and river cleanups.
The second public lecture in this series will take place on Wednesday, May 3, 6 pm at St. Andrew’s Episcopal Church. The presentation will focus on the cultural history of Richmond as a port and center around Richmond’s maritime landscape below the Fall Line, highlighting the events and places that have influenced the founding and growth of the city.
Attendees at this lecture will be given details and a chance to sign up for a guided walking tour and cleanup, scheduled for Saturday, May 6, at Ancarrow’s Landing in Richmond’s Manchester neighborhood.
DHR is hosting this event in partnership with the City of Richmond Department of Parks, Recreation and Community Facilities’ James River Park System and the Current Culture Fly Shop. The event is part of a series that satisfies the outreach component of a larger DHR program supported by grants from the Chesapeake Bay Restoration Fund. The program seeks to collect additional data on the maritime history of the James River. The Chesapeake Bay Restoration Fund is financed through a portion of the proceeds from the annual subscription fees of the “Friends of the Chesapeake Bay” license plates.
