The Louisiana coastline loses an average of more than 16 square miles of wetlands per year according to the U.S. Geological Survey. The Coastal Protection and Restoration Authority of Louisiana (CPRA) is the single state entity with authority to develop, articulate, implement, and enforce a comprehensive coastal restoration and protection master plan to reduce hurricane storm surge flood impact, restore Louisiana’s bountiful natural resources, build land to protect critical energy infrastructure, and secure Louisiana’s coast now and for future generations. CPRA selected the Tetra Tech team to design a bio-engineered oyster reef demonstration project to show the potential of using reef breakwater product to combat coastal erosion in St. Bernard Parish. This project was funded through the Coastal Impact Assistance Program (CIAP) and is part of Louisiana’s Comprehensive Master Plan for a Sustainable Coast.

The project is located in St. Bernard Parish’s coastal fringe marsh, which is susceptible to high rates of shoreline erosion due to wind-wave action. The project aimed to establish a living shoreline along 21-miles of coastal fringe marsh to dissipate wave energy before it reaches the shoreline thereby protecting vulnerable shoreline and the valuable marsh behind.

The Tetra Tech team evaluated reef breakwater products to serve as a first line of defense for coastal marshes in the project area, helping to sustain the lower Biloxi Marsh. The project’s secondary goals were to allow sediment accretion between the shore and reef to create new land; stimulate oyster growth and increase the biodiversity in the immediate area; and provide CPRA with valuable data on the performance of various configurations of the selected products that can be used to design more effective projects in the future.

Our team evaluated numerous living shoreline products to determine their potential to meet project goals. Products evaluated included A-jax, gabion mattresses, Reefballs, Reefblk, Hesco basket, and OysterBreak.

The Tetra Tech team performed an environmental analysis of each product, including determining its ability to promote oyster growth, thereby increasing the biodiversity in the immediate area. Our team used analytical and numeric modeling to evaluate the shoreline response and performance of the alternatives using parameters including wave attenuation and sediment transport.

The Tetra Tech team’s services for the living shoreline demonstration included:

Recent and historical data collection (topographic, bathymetric, and geotechnical)
Coastal engineering and modeling analysis
Preliminary engineering and design
Regulatory compliance
Final design
Construction administration support, primarily ensuring all environmental requirements in the permits and specifications were followed
The engineering and design of the project met all three project goals, and our team obtained all necessary permits on schedule to complete project construction during the grant funding period.

Using living shoreline products to protect coastlines in Louisiana provides ecosystem services not available through traditional shoreline protection techniques. The products evaluated as part of this project will provide habitat for fish and other aquatic species, in addition to providing erosion control and shoreline stabilization. Project construction was completed in November 2016, and CPRA is conducting monitoring to evaluate the results of the living shoreline products’ performance.

Dedication to 65 lost submarines.

– In IndustryPRWeb

The first undersea memorial to these 65 lost submarines will be dedicated 27 MAY 2018 in Sarasota, nearly 50 years after loss of the USS Scorpion (SSN-589).

Military honors will be given for the 65 lost boats and 4,000+ submariners at the On Eternal Patrol Memorial Reef dedication.

We can think of no more fitting memorial to these heroes who made the ultimate sacrifice under the waves. These submariners will continue to serve and protect our marine environment for the benefit of future generations in the On Eternal Patrol Memorial Reef.

SARASOTA, Fla. (PRWEB) May 21, 2018

Tomorrow marks 50 years since the U.S. nuclear submarine the USS Scorpion (SSN-589) was lost with all hands, 99 officers and crew, on 22 May 1968. She is one of 65 U.S. submarines that have never returned from duty since 1900.

Representing more than 4,000 service members, these 65 boats and crews will be honored this Memorial Day weekend with full military honors at the dedication of the On Eternal Patrol Memorial Reef at 10 a.m. on Sunday, 27 May at Ken Thompson Park, 1700 Ken Thompson Parkway, Sarasota, FL 34236. The public is invited and many military service personnel and veterans are expected to attend.

This first ever undersea memorial will be a collection of 65 Eternal Reef balls with plaques identifying each of the submarines still On Eternal Patrol and one additional Eternal Reef ball representing those crews and boats lost in non-sinking incidents. The 66 Eternal Reefs will be deployed to the ocean floor off the coast of Sarasota this summer to significantly boost the marine environment in which these submariners served and made the ultimate sacrifice.

“We can think of no more fitting memorial to these heroes who made the ultimate sacrifice serving our country beneath the waves and it’s particularly impactful that we will make the dedication nearly 50 years to the day after the loss of the Scorpion,” said George Frankel, Eternal Reefs CEO. “These submariners will continue to serve and protect our marine environment for the benefit of future generations in the On Eternal Patrol Memorial Reef.”

A reef ball is a designed artificial reef, specifically engineered to mimic Mother Nature and quickly assimilate into the ocean environment; new marine growth begins in as little as three months. The reef balls in the On Eternal Patrol Memorial Reef each weigh about 1,300 pounds and stand three feet tall.

Full military honors will be presented on 27 May, including rifle salutes, buglers playing taps and an honor guard bestowing folded flags to representatives for each lost submarine. For many, this will be the first time they’ve been recognized collectively for their contribution and sacrifice.

Dave Taylor, Past Commander Disabled American Veterans Chapter 97, will be the master of ceremonies at the dedication of the On Eternal Patrol Memorial Reef. Rear Admiral Thomas Logan Malone, Ed.D, U.S. Navy (Ret) will be the guest speaker at the event and Colonel Charles Caudill, U.S. Air Force (Ret), will be the officiating chaplain and offer the invocation and prayers. Students from Port Charlotte High School Naval Junior ROTC Unit will present the colors under the supervision of Cadet LCDR John Flaws.

Additionally, middle school cadets from the Sarasota Military Academy Prep School(SMA) will be at the dedication ceremony as “cadet experts,” providing guests background on each of the lost 65 subs. The 72 sixth and seventh graders are supervised by Major Alex Vanston, USMC (Ret) and Captain Terri Davis, both military studies instructors at SMA Prep. Christina Bowman is SMA’s executive director of schools.

A Sarasota-based 501c3 memorial organization, Eternal Reefs, Inc., has planned the ambitious project, in partnership with Reef Innovations and The Reef Ball Foundation. The On Eternal Patrol Memorial Reef has already garnered recognition from more than 25 states, including gubernatorial proclamations from Alabama, Delaware, Indiana, Massachusetts, Michigan, Nebraska, New Hampshire, New Mexico, Ohio and Wisconsin, to name a few.

Submarine enthusiasts, veterans and other military representatives plan to attend from around Florida and across the United States. Brian Lawrence, a Navy veteran from Missouri, is attending in honor of RM2 Kenneth Eugene Nearman, who was aboard the USS TROUT (SS-202) when it went down on 27 February 1944 with all hands, 81 officers and crew. Lawrence shared that his late mother dated Nearman while in and after high school in Missoula, Montana and often spoke of him, and cried, well into her 90s.

Michael Burasco, from Ocala, Fla., plans to attend to honor his brother, Nugent Anthony Burasco, who was one of 79 men lost on the USS Tullibee (SS-284) when she went down on 26 March 1944. James Jordan — who moderates the Facebook submariner group OTS at Crush Depth and served aboard on the USS Parche (SSN-683), the USS Daniel Webster (SSBN- 626), and the USS Sam Rayburn (SSBN-635) – plans to attend and be aboard his own boat to witness the deployment of one representative Eternal Reef on the reef site, weather permitting.

US Armed Forces building oyster reefs

With over 900 Reef Balls deployed this is truly a great cooperative effort.  Watch the video to see how they were deployed and why.   Then think creatively about a project for your area.   Oysters are important and we have lost so many in the waters around the world.  What will you to to restore marine habitat?
