The TFMoran Stormwater Team is working with R.S. Audley of Bow, NH on the NHDOT F.E. Everett Turnpike widening project that includes replacing two 70-year-old bridges over Bowers Pond; the main source of Nashua’s water supply. The TFMoran team prepared the stream diversion, dewatering, erosion control, and stormwater pollution prevention plans (SWPPP) for the project.

In addition to preparing the environmental plans for the project, TFMoran’s EPA Certified personnel are providing turbidity monitoring while R.S. Audley is performing in-water work to confirm the project is compliant with the NH Surface Water Quality Standards.

Preparatory work began in the spring on a new six-lane bridge that will cross Bower’s Brook and Pond, a reservoir located beneath the F.E. Everett Turnpike, connecting Nashua and Merrimack between Exits 8 and 10. This work includes placing fill material in the pond where the new bridge approaches are and monitoring the material for settlement prior to constructing the new bridges.

While ensuring smooth traffic flow during this vital highway widening project from Nashua to Bedford has been a primary focus, equally important is safeguarding the drinking water supply and protecting the wildlife in the surrounding undeveloped woods.
