CONCORD, Mass. – The Newburyport Harbor north jetty in Salisbury, Mass., and the south jetty in Newburyport, will be repaired under the terms of an $8,276,236.00 contract issued recently by the U.S. Army Corps of Engineers, New England District. Work will be accomplished by Cashman Equipment Corp., of Braintree, Mass. Construction is scheduled to start in late April 2015 and take about 12 months to complete. The contract was awarded on April 2, 2015.
“Work consists of repairing the 3,100-foot-long north jetty in Salisbury and completing repairs to the remaining most seaward 140 feet of the 1,500-foot long south jetty in Newburyport that were damaged during Hurricane Sandy,” said Project Manager Jack Karalius, of the Corps’ New England District, Programs/Project Management Division in Concord, Mass. “Approximately 30,000 tons of armor stone will be required, including approximately 5,000 tons of 14-to-19-ton armor stone.”
Newburyport Harbor is about 2.5 miles long and stretches from the mouth of the Merrimack River to the U.S. Route 1 Bridge. It is four miles south of the Massachusetts/New Hampshire state line. The harbor is home base for charter excursion and sport fishing boats, as well as many recreational craft.
Crest width varies from 5 to 15 feet. Crest elevation at the most seaward end is +12.3 feet mean lower low water (MLLW) and +17.3 MLLW at the landward end. Work includes replacing displaced core and armor stone to fill in existing gaps in the jetty. Repairs will require substantial moving and rehandling of existing stones to obtain the required interlocking placement. Work also includes repair of a 190-foot long stone spur off the north jetty, approximately 600 feet seaward from the beginning of the jetty, and removal of two navigation aids from the north jetty and installation of new concrete bases.
Funding is provided by the Disaster Relief Appropriations Act of 2013. The project will be managed by the Corps under the supervision of a Corps’ Quality Assurance Representative to assure compliance with contract requirements.
