CEDARVILLE conducted a stormwater management study for a Township-owned roadway within the Culbertson Run Development of East Brandywine Township. The goal of the study was to provide the Township with several alternatives and associated costs to effectively improve the existing stormwater management along Hawthorne Drive, alleviating public concerns. The project was designed to minimize impact to private property, existing landscaping and mature street trees valued by the community.

Emphasis was placed on green stormwater infrastructure practices while considering all environmental and socio-economic factors. To assess potential management strategies, a multi-faceted approach was utilized to identify comprehensive solutions to the ongoing stormwater runoff problems in the community to reduce impairment to Culbertson Run.

The study includes a topographic analysis and survey, land cover quantification, existing conditions evaluation, soil investigation, engineering analysis, tree health assessment, and a resident survey, which ultimately contribute to a comprehensive stormwater management plan utilizing Best Management Practices (BMPs). The project involved the utilization of Geographic Information Systems (GIS) to delineate and quantify sub-basins and impervious coverage in conjunction with stormwater modeling. Infiltration trenches are proposed within the road right-of-way in select locations to minimize street tree removal. The project is currently in the design phase with construction anticipated in 2018, pending the resolution of utility conflicts within the right-of-way.
