Where environmental wellbeing meets community connection.

At Summit, we strongly believe in improving and enriching the communities we serve. We achieve this by ensuring that every project we work on has minimal impact on the environment so that future generations can enjoy these projects for decades to come. Our commitment to being environmentally conscious and sustainable is reflected throughout our service areas, from utilizing permeable pavements to using the Pathfinder tool to mitigate our carbon footprint. We also have the inaugural Stormwater Planning & Compliance team to take our capabilities to new, sustainable, and community-oriented heights. That’s the dedication you can expect from Summit- one that seamlessly blends utility, safety, and function while benefiting the world we call home.
