In the 1950s, an industrial complex that housed the Verdelli Farms vegetable processing facility was built in the Hummelstown borough in Pennsylvania, but in 1993, it permanently shuttered, leaving the the 5-acre property vacant. 

As redevelopment efforts have increased, along with the need for housing opportunities, a property named VERDE was developed to include six new residential buildings, parking, a fitness center, a maintenance building, four multi-car garages, sidewalks and more.The redevelopment strategies had to match the neighborhood’s existing context, meet storm water regulations and comply with all applicable environmental requirements. 

Given the borough’s green infrastructure and storm water management requirements for peak flow attenuation and nutrient discharge reduction, creative storm water planning was integrated into the design process.

Hummelstown sits within the Chesapeake Bay watershed and because the site is underlain with karst geology, specialized hydrologic modeling was needed to represent the runoff associated with these areas. Four water-tight underground storm water facilities and conveyance infrastructure improvements were implemented. Additionally, project officials conducted a water quality analysis and implemented BMPs for the removal of total suspended solids, nitrogen and phosphorus in accordance with the General NPDES permit requirements. 

“The Verde project is an important and replicable example of urban redevelopment that implements a number of cost effective solutions for developers and communities to consider,” said Len Bradley, P. E. with RGS Assn. Inc.
