Mr. Cole has been working in the land development sector of New Hampshire for nearly a decade since graduating from the University of Massachusetts Dartmouth with a BS degree in Civil Engineering.  He began as a project engineer for a small firm north of Concord where he worked directly with the owner to develop his skills in land design, CAD, and the permitting process.  Mr. Cole transferred to a larger firm outside of Manchester in 2014 where he earned his Professional Engineering license and became a project manager.  Mr. Cole has nearly 10 years of experience in engineering and managing residential, commercial, and industrial site plans, roadways, subdivisions, and other related projects. He has established roots in the city with his wife, Melissa, who is also a Professional Engineer in the state, and young daughter Lainey.   His passion is his family and career as he looks forward to advancing responsible development in the Granite State.

The Commission's responsibilities include advising the NH DES on applications to disturb wetlands; cataloging, researching, and planning for the protection of natural resources, including watersheds, open spaces, wetlands, and endangered species; acquiring property interests in land to hold in conservation; promoting conservation activities; and advising other boards, such as the Planning Board and Zoning Board of Adjustment, on environmental impacts of development.
