CROWDER • ®®® CrowderGulf�:iLF RFP Disaster Debris Management and Disposal Services 18-04-02 City of Sunny Isles Beach, FL 2012 Tropical Storms Beryl and Debby; Hurricanes Isaac and Sandy Tropical Storms Beryl and Debby- Following two early season tropical storms, CrowderGulf was - activated for debris removal in Nassau County, FL; Polk County, FL; and the Town of Fort Myers Beach, FL.The work consisted of hauling and reducing vegetative debris and cleaning and restoring beaches. "Wu Hurricane Hurricane Isaac- CrowderGulf had nine contracts activated across three states. Our work ranged _ t= �f—ter_-� from providing emergency"Push"operations in Key West, FL, sand removal and sand screening fors E the Town of Dauphin Island,AL, to debris removal and reduction, providing generators and removal r r y.� of hazardous leaners and hangers. , � - �: Hurricane Sandy — This late season storm at the end of October affected the entire Eastern Seaboard from Florida to the New England states. By far, the greatest damage was inflicted on the New York and New Jersey coasts. • As part of the"Superstorm Sandy"cleanup,the State of New Jersey Department of Environmental Protection(NJDEP)awarded three waterway contracts in January, 2013. CrowderGulf was awarded the central coast of New Jersey where the worst damage occurred. In this area, the ocean surged over the densely populated chain of barrier islands and into Bamegat Bay causing massive destruction to the homes in its path. As a result, debris, sand, and multiple homes were washed into the Bay. Some homes were left almost intact while others were torn apart and strewn across the Bay waters. CrowderGulf was tasked with removing all storm related debris from the Bay and all tributaries in the central region of New Jersey, including wetlands and salt marshes. Submerged debris required using side scan sonar to locate and document the submerged storm debris. CrowderGulf conducted side scan sonar, evaluated the results, and then directed crews to remove the identified debris.Over 100,000 cubic yards of submerged and floating debris were removed. Crews completed the removal of eligible floating and submerged debris in approximately eight months. Part of this operation was the management of the aggregate site for the vessels and vehicles removed from the waterways,which included 6 vehicles and 1.17 vessels. The total project value for this contract with the NJDEP was over$57,000,000. The Sandy waterway project in New Jersey presented several unique situations such as the requirement that no waterway debris could touch the ground.The debris had to be off-loaded directly into a debris hauling truck and taken to the final disposal site. CrowderGulf had to secure several off-loads sites and each site had to be approved by the NJDEP. Both public and private sites were identified and all necessary documentation secured before any site was used. Besides removing eligible submerged debris, four large homes that were pushed into Barnegat Bay had to be demolished and removed. This was a slow and careful process conducted on the water using long-reach track hoes with grapples on barges to take the houses apart and load the debris onto debris barges. The house debris was taken to the off-load site and loaded into Q the hauling trucks for disposal. The tremendous amount of debris that was deposited in the wetlands and salt marshes presented another unique situation. CrowderGulf was tasked with removing the eligible debris while ensuring minimal disturbance to these areas.CrowderGulf used Q specialized low ground pressure amphibious equipment to minimize further damage to the sensitive areas. In addition, all work was scheduled to accommodate the endangered/protected species in the region. Another unique aspect of this contract was the removal of over 300,000 cubic yards of displaced sediment that Sandy washed into Bamegat Bay. The operation involved mechanical dredging,hydrographic surveying,staging the dredged sediment for drying,screening the sediment,replacing beach quality sand on the ocean side, and hauling the remainder of the sediment and debris to a certified disposal site. a` As a result,over 320,000 cubic yards of displaced sediment were dredged from the Bay areas and over 100,000 cubic yards of sediment were screened and returned to beach quality sand. The documentation for this part of the Sandy project required a combination of measures be implemented to document the dredged sediment. Pre-and post-hydrographic surveys were used in measuring the dredging that was done. The dirty and screened sediment,and resulting debris,were measured by truck loads and documented using cubic yards and truck load tickets. II17
