DOWNLOAD OUR BROCHURE
We’ve had a great working relationship with Riverside & Pickering Marine Contractors since 2015. Each year, Dr. Raymond Grizzle and I (University of New Hampshire) have designed and implemented oyster reef restoration projects in Great Bay. R&P has played a vital role in storing and deploying clam shell for these projects. Ken and their barge crew are professional and are always willing to work with us when sites can be challenging. By deploying shell, R&P is contributing to the overall health of Great Bay in New Hampshire. Partners include: USDA Natural Resources Conservation Service, The Nature Conservancy, NH Shellfish Farmers, and the Coastal Conservation Association. Thank you, R&P!

We had a chance to take a look at the floats and am happy to say they look great. Riverside and Pickering delivered an excellent product for a reasonable price ahead of schedule. Can’t ask for any more than that. Great work and thanks.
