Cocos Bay is located on the eastern coastline, south of the Nariva River Mouth on the Mayaro-Manzanilla Road. South Cocos Bay is within Cocos Bay, at the Nariva River Mouth. For many years the Manzanilla-Mayaro Road has been affected by flooding during high tides and sections of this roadway have been eroded due to such activity. The shoreline is also being eroded. A shoreline protection scheme was implemented to reduce erosion and inundation.
SCOPE OF WORKS
At South Cocos Bay,
- The installation of sheet pile seawall
- Construction of 735 linear meters of rock revetment;
- Ancillary works.
At Cocos Bay ,
- The construction of 500 linear meters of rock revetment; ancillary works.
BENEFITS OF THE PROJECT
- Preventing damage to public and private properties, and infrastructure
- Eliminate the loss / damage to the Manzanilla-Mayaro Road;
- Reduce losses in the productive sector as a result of traffic and other disruptions are the main benefits of the project.
- Cocos and South Cocos Bay Shoreline Stabilization Works (October 2019 and February 2020 respectively)
Problem Identification: Severe coastal erosion and flooding affecting the Cocos Bay (Manzanilla) Area. Coastal erosion flooding has impacted several public assets, of which the most critical is the Manzanilla-Mayaro Road. Much of this road, which is the main thoroughfare on the South Eastern end of the island, had been destroyed by a severe coastal flooding event in 2014.
Solution & Scope of Works: ¨A rock revetment system (Figure 1) 1240m long¨ 66m Reinforced Polymer Seawall¨Boardwalk¨Easy beach access points¨
Results To date no reports of coastal flooding have been recorded along the Manzanilla-Mayaro Road. The site is regularly frequented by tourists on the weekends and on holidays
