At the request of the East Brandywine Township Board of Supervisors, CEDARVILLE Engineering Group has performed a Comprehensive Stormwater Management Study for Hawthorne Drive within the Culbertson Run development.

The Culbertson Run development has a history of complaints from residents regarding drainage and erosion concerns along Hawthorne Drive. The residential development was designed in the early 1970s as a community of single family homes, townhomes, and amenities.

The Hawthorne Drive Right-of-Way (ROW) originally contained roadside swales to convey drainage. Street trees that were planted within these swales and have become quite large and an important aesthetic feature within the development. The trees are impeding the functionality of the original drainage system in many locations by interrupting flow patterns and causing sediment deposition that has filled in the swale.

CEDARVILLE has conducted a detailed assessment to identify the concerns, analyze their implications, and propose potential solutions.
