The contractor will place 220,000 cubic yards of beach-quality sand from an upland mine on more than 3,000 feet of critically eroded shoreline to widen the beach to approximately 230 feet in two locations, near 46th Street and 54th Street. The project provides coastal storm risk management, including beach erosion control and hurricane surge protection. Beach renourishment projects protect infrastructure, preserve wildlife, support the economy, and build coastal resiliency. The approximate areas affected by construction include the 4400-4700 and 5300-5500 blocks of Collins Avenue, and access points and staging areas at Indian Beach Park and Beach View Park. The contract award to Eastman Aggregate Enterprises, LLC was for $11,889,480.65. Construction fill operations, tilling, demobilization and restoration of the 46th Street access is scheduled to be complete by Nov. 9, 2016, with the remainder of the project complete by spring 2017. The contractor will work weekdays, and weekends as needed. Approximate work hours at the access and staging areas, including the delivery of sand, will be 6 a.m. through 11 p.m. Beach work will take place between 7 a.m. or sunrise, whichever is later, through 7 p.m. or sunset. Construction will commence after daily sea turtle and shorebird monitoring is complete and the area is cleared for construction. Safety is our first priority. Due to safety concerns, some beach access areas will be closed and public access to the beach will be restricted during construction. Because of the extensive construction activities for the next several months, motorists, cyclists, pedestrians and beach goers are asked to use caution along these areas of Miami Beach. Miami-Dade County will conduct migratory shorebird and sea turtle monitoring daily, and relocate sea turtle nests if necessary. If there are any sea turtle nests in the construction area, they will be monitored and protected until the hatchlings have emerged from the nest. After daily environmental species monitoring and sea turtle nest relocations have been completed and the area has been cleared for construction, beach work will commence. However, construction operations in the area will cease if sea turtles are present at any time.

La compañía contratista verterá 220,000 yardas cúbicas de arena extraída de una mina en un área montañosa sobre un segmento de más de 3,000 pies de litoral afectado críticamente por la erosión, a fin de ampliar la playa hasta aproximadamente 230 pies de ancho en dos lugares, cerca de 46th Street y 54th Street. El proyecto provee el manejo del riesgo de tormentas costeras, incluyendo el control de la erosión de la playa y la protección contra el oleaje producido por huracanes. Los proyectos para la reposición de arena de playa protegen la infraestructura, conservan la fauna, apoyan la economía y promueven la resiliencia costera. Las áreas aproximadas donde tendrá lugar la construcción son entre las cuadras 4400-4700 y 5300-5500 de Collins Avenue, así como puntos de acceso y áreas de almacenamiento temporal en Indian Beach Park y Beach View Park. El contrato fue concedido a la compañía Eastman Aggregate Enterprises, LLC por la cantidad de $11,889,480.65. La fecha planeada para la finalización de las operaciones de relleno y arado de la playa, demobilización y restauración del acceso a 46th Street es el 9 de noviembre de 2016. El resto del proyecto terminará antes de la primavera de 2017. La compañía contratista trabajará de lunes a viernes y según sea necesario, los fines de semana. El horario de trabajo aproximado en las áreas de acceso y de almacenamiento temporero, incluyendo la entrega de arena, será de 6 a.m. a 11 p.m. La obra en la playa tendrá lugar entre 7 a.m. o el amanecer, lo que ocurra más tarde, hasta las 7 p.m. o el atardecer. La obra comenzará luego de observar y comprobar que no haya tortugas marinas y aves costeras en el área. La seguridad es nuestra principal prioridad, y por ese motivo, ciertas áreas de acceso a la playa estarán restringidas al público mientras la obra esté activa. Debido a la construcción, habrá un extenso movimiento de maquinaria pesada durante los próximos meses. Se les pide a los automovilistas, ciclistas, peatones y bañistas que usen extrema precaución al transitar estas áreas. El Condado de Miami-Dade hará una inspección diaria de aves migratorias costeras y tortugas marinas, y según sea necesario, reubicará los nidos de tortugas marinas. Si se encuentra algún nido de tortugas marinas en el área de construcción, se le vigilará y protegerá hasta que las tortugas hayan salido del cascarón. Las obras en el litoral comenzarán solamente cuando se haya realizado la inspección diaria de especies y la reubicación de nidos de tortugas marinas y se haya comprobado que el área está lista para la construcción. No obstante, se detendrán las operaciones de construcción en el área si se observa la presencia de tortugas marinas en cualquier momento.

 Dade County officials requested federal assistance with shore erosion about 50 years ago, and Congress authorized the Corps of Engineers to construct the Dade County Beach Erosion Control and Hurricane Protection Project in 1968.
The Dade County project provided for the placement of beach fill along 9.3-miles of shoreline extending from Bakers Haulover Inlet to Government Cut and along the 1.4-mile length of Haulover Beach Park located immediately north of Bakers Haulover Inlet. The 2.4-mile length of the Sunny Isles segment was added to the project in 1985 under a separate authorization.
All major sand sources offshore of Miami-Dade County have now been exhausted with the completion of the latest nourishment contract in the Bal Harbour area in 2014. The Corps and local and state coastal officials estimate that an additional 3.6 million cubic yards of sand is needed for the remaining federal participation, which is ten years for the Government Cut to Baker’s Haulover Beach Park segment and 23 years for the Sunny Isles segment.
Section 935 of the Water Resources Development Act of 1986 and a Congressional directive from 1999 indicate that the Corps can only use domestic sources of sand for renourishment of this project, unless domestic sources are not available for environmental or economic reasons. To utilize new sand sources, the Corps completed a Limited Reevaluation Report (LRR) and Environmental Assessment (EA) with updated economics to justify potential alternative sand sources for future renourishments.
