A developer proposes 64 apartments at 501 Washington Street in Whitemarsh Township. The county summary describes four four-story buildings on about 4.3 acres. Each building would have rear-entry garages, and every unit would have parking.

The site lies in the Schuylkill River floodway, the part of a floodplain that carries water during a major flood. It is also subject to a 1% annual flood hazard, meaning a flood with a 1-in-100 chance of happening in any year. County planners called this a serious concern. They said it needs a flood mitigation plan.

No news coverage, township agenda item, developer page or approval decision was found for this specific project. This explanation therefore rests on the county planning record alone.
