SAND BYPASS & BEACH RENOURISHMENT – FREQUENTLY ASKED QUESTIONS
Where and when will the 2018-19 sand bypass project place sand?
The project will start placing sand just south of Jetty Park, about ¼-mile south of the Canaveral Harbor south jetty, and progress northward along Jetty Park. Once that is complete, sand placement will commence southward from Jetty Park and continue throughout the entire City of Cape Canaveral shoreline and north Cocoa Beach. The sand placement will conclude about 6/10’th of a mile south of the Cocoa Beach Pier (that is, just north of the SR 520 / Cocoa Beach Causeway), covering a total shoreline distance of 3.5 miles beginning south of the south jetty.
Initially, most equipment and dredge pipe will be brought onto the beach at Washington Avenue, near Cherie Down Park, City of Cape Canaveral. This will occur during November. The dredge is currently anticipated to begin pumping sand onto the beach by the first week of December 2018 and to be completed by late April 2019.
How long will the project take?
From start to finish, and assuming reasonable weather, the dredging and sand placement onto the beach is expected to take about 4-1/2 months. Project construction is to be completed prior to May 1, 2019. In typical conditions, the sand fill placement will progress by about 100 to 150 feet alongshore each day.
See the Progress Map on the olsen-associates.com/canaveral web-page for a regularly updated project schedule.
What are the working hours for the project?
The project is permitted for, and will be constructed, 24 hours a day, seven (7) days a week.
How much sand is being placed on the beach by the project?
Approximately 1,340,000 cubic yards of sand will be placed upon the beach during this project. This is about 3.4 times as much sand volume as was placed during the recent beach nourishment after Hurricane Irma, in Winter 2017-18, along this 3.5-mile shoreline area south of the inlet. And, it is about 1.9 times as much volume as was placed during the last sand bypass project in Spring 2010; however, that project placed sand only along 2.2-miles of shoreline south of the inlet, whereas the 2018-19 project will place sand along 3.5-miles.
Why is the beach being renourished again?
The beach renourishment in Winter 2017/18, constructed as part of the Brevard County Federal Shore Protection Project, repaired storm damage to the beach and dunes caused by Hurricanes Matthew and Irma in 2016 – 2017. The upcoming 2018/19 sand bypass placement, constructed through the Canaveral Harbor Federal Sand Bypass Project, is a regular ‘maintenance’ operation that periodically moves sand that has accumulated north of the inlet to the beach south of the inlet. This is required in order to maintain the beach in its normal condition, moving sand from north to south along the shoreline that is otherwise interrupted by the presence of the inlet channel and jetties. The sand bypass project is typically constructed every six years, on average.
Where does the sand come from?
Sand is being dredged from the beach face and the nearshore, between the high tide shoreline and about -18 ft depth, along 1.6 miles of beach immediately north of the inlet, at the Cape Canaveral Air Force Station. The sand unnaturally accumulates along this shoreline, impounded against the inlet’s north jetty. If it is not periodically dredged and bypassed (pumped via pipeline) to the south beach, the sand spills around the north jetty and into the inlet channel.
Does the sand differ from the natural beach and the usual renourishment projects?
The sand placed from the sand bypass project comes from the beach and nearshore seabed on the north side of the inlet, so it is all “beach sand” common to Brevard County beaches. Because it is dredged from the entire beach profile – from the high tide line to 18-ft depth – the sand is typically finer-grained than the sand that is on the beach berm above high tide. And, the sand is finer-grained than the sand that is dredged from Brevard’s offshore borrow sources and pumped onto the beach for renourishment projects. So, the beach sand will be a little finer-grained and flatter-sloped, at least initially after the sand bypass project is constructed, relative to current conditions. The sand may also initially appear a little darker than the existing beach sand, at least until it dries and bleaches out in the sun after a few days.
Does the dredge and pipeline block the inlet?
No, the dredge operates north of the inlet, along the Cape Canaveral Air Force Station beach. The temporary 24” diameter pipeline, through which the sand is pumped with water from north to south, is placed in a trench at the bottom of the inlet channel — below the navigation depth of the inlet – so that it does not interfere with shipping. The pipeline is removed after the project is completed.
Will there be access to the beach during the project?
The beach will remain open to residents and visitors outside the active work areas. The contractor expects to temporarily close about 1,000-feet length of the beach at a time during the project. Access over the 24-inch diameter dredging pipe will be provided at street ends and at least every 300 feet alongshore. The work should proceed about 100 to 150 feet or more along the shore each day. So, typically, access to the beach at any particular location will be closed for only about 3 or 4 days as the renourishment work progresses up the beach. During that time, the beach should be accessible at an adjacent beach access or walkover to the north or south.
Are parts of the beach going to be skipped?
No, the project plan is to place sand along the entire 3.5-mile shoreline south of the inlet’s south jetty, from Jetty Park to the SR 520 Cocoa Beach Causeway, without interruption. The final length of shoreline that is covered (if not quite all the way to SR520) will depend upon the Contractor’s daily-tracked progress with the sand fill placement before reaching the contract’s target volume of 1,340,000 cubic yards of sand bypass dredging.
Will there be vibration monitoring along the beach front for existing structures?
Yes. A structural engineering firm is contracted to monitor vibrations from the construction equipment throughout the project.
What can be done about the noise from the machinery back-up alarms?
The back-up alarms cannot be turned off. The alarms are a safety device required by Federal law to protect people from being hit by machinery when the driver is unable to see directly behind his equipment.
How does this project impact sea turtles?
There are no marine turtle nests on the beach that will be affected by the November-December start-up of the work. Daily early-morning monitoring by state-permitted turtle observers will begin in early March and continue through construction (and afterward through the summer). Marine turtle nests that may be impacted by the construction – on both the dredging side and the sand placement side – will be relocated to safe locations outside the work area.
Will the project rebuild dunes or plant sea oats?
The sand bypass project will place sand along the beach berm beginning just seaward of the existing dunes. (Some sand will be placed around the existing foredunes at Jetty Park where the beach berm is quite low.) It will not place sand to the dunes. The project will not place new dune vegetation or sand fencing. Planting by individuals may take place after the beach fill is completed. A field permit from the Florida Dept. of Environmental Protection (FDEP) is necessary for dune planting. It is noted, however, that planting or expanding dune vegetation beyond its existing seaward limits is not recommended because the current dune/vegetation line is already located mostly seaward of its historical natural, limit that can be maintained by the beach projects.
Who pays for the project?
The federal government (US Army Corps of Engineers) pays 100% of the construction costs for the Canaveral Harbor Sand Bypass Project. The construction contract for the 2018-19 project is about $18,100,000. The Canaveral Port Authority is the FDEP permittee for the project and provides additional fiscal and logistical support through construction coordination, physical and environmental monitoring – with cost-share support from the State of Florida.
