Happy Earth Day! 🌎 🍃 🌱
We had a busy year at the Pease Development Authority (PDA). Last summer, the PDA, in conjunction with the City of Portsmouth, completed the reconstruction of Corporate Drive, which included important improvements to the Tradeport’s ecosystem.
The reconstruction project included the addition of new drainage systems and catch basins (including hoods) along Corporate Drive. Ten new Rain Guardian Bunkers were installed along the roadway to remove leaf litter, trash, and debris. The debris is captured by a metal grate and corrosive-resistant aluminum filter, which then empty into vegetated swales connected to five high-rate FocalPoint Bio-Filtration systems. These systems are designed to further filter the stormwater by removing solids, phosphorus, nitrogen, and bacteria.
The PDA also installed an infiltration basin to collect stormwater at the intersection of New Hampshire Ave, Arboretum Drive, and Pease Blvd. The basin provides additional stormwater treatment by allowing the stormwater to infiltrate into the ground and reduce potential stormwater impacts downstream.
The Corporate Drive reconstruction project required extensive coordination and planning, resulting in meaningful improvements to the Tradeport for both our tenants and the surrounding environment. We’re incredibly thankful to our team at the Pease Development Authority and the City of Portsmouth for their dedication and hard work in bringing this important project to completion!
