PORTFOLIO SERVICES ABOUT CONTACT SERVICES CULVERTS, BRIDGES AND BOARDWALKS SumCo-Eco Contracting has completed more than 50 culvert, bridge, pier and boardwalk projects. Our clients’ structures are present in municipal and state parks and wildlife refuges, at golf courses, in industrial, commercial and residential developments, access roads and elsewhere. Many of our projects involve removal and replacement of structures no longer fulfilling their original purpose. Project examples include natural-bottom box and arch culverts to improve flow capacity and wildlife passage; piers; timber pedestrian boardwalks; pile-supported footbridges; timber bridges; and concrete arch and steel vehicular bridges. Every project is different. Ours often include overcoming complex site access challenges, installing water controls, constructing scour protections, dredging accumulated sediment to restore flow, and stabilizing stream and riverbanks.

PORTFOLIO SERVICES ABOUT CONTACT SERVICES NATIVE PLANTINGS AND SEEDING Native plants serve not only as a food source and shelter for local wildlife, but also perform as natural pollutant filters, erosion controls, and more. Our teams have exceptional planting and seeding experience developed across hundreds of projects of all shapes and sizes in a diversity of challenging settings. Successful ecological restorations depend on establishing plant communities that will thrive in the future while coexisting with their current environment. That’s why we take great care in creating optimal conditions for our plants and seeds to flourish. Whether planting tens of thousands of Cordgrass plugs in a salt marsh or five-inch caliper Oaks in a public park, we’re dedicated to getting the right plants in the right places, benefiting our clients, communities, and the local habitat.
