TFMoran Stormwater Department: Balancing Infrastructure and Nature in Nashua, NH

September 26, 2024 | 0 Comments | , , , , , ,

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.

Check out Union Leader’s full article to learn about the project’s full scope and how the project teams are balancing between necessary construction and the importance of preserving nature.

Paul O’Hanlon is now a Certified Erosion, Sediment and Storm Water Inspector

October 3, 2023 | 0 Comments | , , ,

Paul O’Hanlon, an Environmental Permitting Specialist for TFMoran’s Bedford office, recently received his Certification in Erosion, Sediment and Stormwater Inspection (CESSWI). He joined TFMoran’s Stormwater Monitoring team in 2021.

A CESSWI is a State and Federally recognized professional certification for comprehensive knowledge and understanding of Erosion, Sediment and Stormwater Regulations. On many jobs and in many specifications CESSWI Certification is a requirement. Every year regulations and enforcement of State and Federal agencies increase. Having CESSWI professionals on site can ensure proper compliance of subjects including regulations, safety issues and documentation.

A Day in the Life of TFMoran’s Stormwater Department

July 11, 2023 | 0 Comments | , , ,

A few weeks ago, Marketing Intern Jackie Gamache had the opportunity to tag along with the Stormwater department for a day in the field. On Wednesday, June 21st, Jackie shadowed Senior Project Manager, Dan Blais, and Stormwater Engineering Intern Brooke Stoncius. They traveled up to North Conway, New Hampshire to check in on some projects the Stormwater Team is currently working on.

Their first stop was a bridge rehabilitation in Tamworth, an ongoing stormwater engineering project close to completion. Dan, Brooke, and Jackie met up with other teams working on the project, including NHDOT to discuss its progress. Dan and Brooke conducted a stormwater inspection of the site. making sure the water runoff was not being affected by the construction activity in the area.

Their next stop was the Mt. Washington Valley Multi-use trail. TFMoran prepared the stormwater pollution prevention plan and is providing stormwater inspection services to The Mount Washington Valley Trails Association. The finished project will be 2.9 paved miles for residents and guests of the area of all ages and abilities. The multi-purpose path can be used for walking, jogging, bicycling, and other outdoor activities.

The trail offers scenic views, access to local businesses, and connections to other trailheads nearby. Once finished, TFMoran will prepare the final wetlands report.

Additional plans for the trail include sections continuing eastward towards Fryeburg and westward towards Bartlett. Eventually, the gaps between each section will be closed, to form a continuous trail system. Learn more about the Mount Washington Valley Trails Association and its projects here.

Jackie had a fantastic day tagging along with the stormwater team. She enjoyed seeing their recent ongoing projects, and all the hard work that goes into Stormwater Engineering!

Thank you Dan and Brooke!

NHDOT I-93 Widening Project receives ASCE-NH 2021 Outstanding Civil Engineering Award

July 27, 2021 | 0 Comments | , , ,

Congratulations to the New Hampshire Department of Transportation (NHDOT) for receiving the 2021 ASCE-NH Outstanding Civil Engineering Award for their work on the I-93 Widening Project from Salem to Manchester, completed this spring. The award was presented during the American Society of Civil Engineers NH section (ASCE-NH) Annual Meeting held on July 14th. TFMoran’s Stormwater Monitoring Team is very proud to be a part of this incredible project that entailed widening a 19.8-mile segment of the interstate from Manchester to the Massachusetts state line, as well as upgrades to 5 interchanges and 45 bridges. The goal was to decongest traffic and enhance the safety of motorists.

TFMoran’s responsibility was to provide Stormwater Pollution Prevention Plans (SWPPP), perform stormwater turbidity monitoring and inspection services for the project. Our team of Certified Professionals in Erosion Sediment Control (CPESC), Certified Erosion and Sediment Stormwater Inspectors (CESSWI) and Environmental Scientists worked closely with NHDOT and NHDES project officials. Construction included many drainage and water quality improvements designed to protect NH’s streams, ponds and lakes along this segment; notably, thousands of engineering hours and millions of dollars were spent to minimize impacts to Canobie Lake and Cobbetts Pond from stormwater from the expansion. The project was designed with the intent to collect and treat stormwater runoff using Best Management Practices (BMPs) such as gravel wetlands, extended wet detention, and infiltration basins; safeguards were also implemented to protect said BMPs.

The TFMoran team also worked closely with the highway builders including R.S. Audley, Weaver Brothers Construction, George R. Cairns & Sons, Severino Trucking Co., Alvin J. Coleman & Sons, and E.D. Swett.
