In 2002, Metro Parks and the Portland community asked the Kentucky Archaeological Survey to revisit the site and examine more of the Portland Wharf for its archaeological potential. Over 60 backhoe trenches were excavated over the entire 55-acre property. Based on the results of the survey it was determined that construction of the floodwall in 1947 disturbed portions of the site, as soil was removed to build the floodwall. However, much of the site contains intact archaeological deposits associated with the wharf, residences, businesses, streets, and sidewalks that were part of Portland during the nineteenth century. One particular city block between 33rd and 34th Street has the most archaeological potential and is the location of Lot 56, which has the remains of residences dating back to the early 1800s.
