- Donohue Engineering provided site grading and stormwater management design for the Teterboro Airport Runway 1-19 Safety Improvements. The project will require the relocation of 1,300 l.f. of Redneck Avenue. The airport drainage basin involved presents challenges both environmentally and hydraulically due to existing C-1 wetlands and tidal flooding from the 10-year storm. Donohue Engineering was responsible for analyzing the proposed stormwater management impacts for compliance with New Jersey Stormwater Regulations due to the relocation.
