Herbert, Rowland & Grubic, Inc. (HRG) is assisting Derry Township in the design and implementation of solutions to overcome significant and reoccurring stormwater challenges in their community. Addressing stormwater issues was named the #1 priority by the Township Board of Supervisors and HRG was able to address this urgent issue with a stormwater improvement project designed to reduce the frequency of flooding for the Township and their residents.
HRG’s professionals performed surveying, preliminary and final design, hydrology and hydraulic analysis, natural stream design, preliminary and final technical specifications, preparation of easement plats and documents, easement acquisitions, estimation of construction costs, permitting, utility coordination, Norfolk Southern coordination, preparation of a project manual and bidding documents, contract award services, contract administration services, and construction observation services.
Total project cost is estimated at over $6 million and the scope of work included drainage design, stream restoration, obtaining two Water Obstruction & Encroachment permits, three NPDES permits, and five Highway Occupancy Permits (HOP). In order to alleviate the high costs associated with this necessary project, HRG successfully guided, applied for, and secured a $1.8 million Pennsylvania Infrastructure Bank Loan and a $4.3 million H2O Grant through the Commonwealth Financing Agency for Derry Township.
HRG was instrumental in partnering with the Township Board of Supervisors to successfully deliver on a promise to their constituents to solve stormwater issues that previously plagued the community.
