52 Beach Sand Cleaning and Marine Debris Removal: Hurricane Ike FEMA DR-1791 Texas General Land Office (calves#on, Harris, Chambers, and Brazoria Counties) Reference: After successfully monitoring the removal of Hurricane Ike debris from municipalities along Texas General Land Office Galveston Bay, Neel-Schaffer was hired by the Texas General Land Office (Texas GLO) to Martha Zottareili, monitor debris removal from state property. Neel-Schaffer monitored the cleaning of beaches - Legislative Liaison affected by Hurricane Ike as well as the removal of marine debris from Galveston Bay, the P.O_ Box 12873 Gulf of Mexico, and other waters along the upper Texas Coast. Neel-Schaffer monitored Austin, Texas 78711- more than $10 million of debris removal and beach cleaning by two contractors. Telephone: 52-463-6119 Beach Cleaning: The first stage of this project consisted of removal of storm debris and Fax: 512-305-89347 cleaning of sand on more than 50 miles of beach on Galveston Island, Bolivar Peninsula, rarthazottarelli@g~ostiate, and the beaches of Brazoria County. Three primary methods were put into action to clean tx.us the affected beaches: The first included loading large debris items onto trucks. The second consisted of °raking° the sand using front end loaders with teeth to remove buried debris. Project Term/ Finally, the sand was loaded and hauled to a large screen, roughly the size of an 18 wheeler. Performance Per7od: December Zoos to Present The sand was then sifted to remove small debris, loaded onto trucks, replaced on the beach, and graded. Neel chaffer monitored, quanfified, documented and graded more than 40,000 loads of sand, completing this cycle more than 250 times a day. Additionally, Neel-Schaffer, the Texas GLO, and HNTB, the Program Manager, determined the most cost-effective methods for cleaning sections of the beaches. Additionally, Neel- - Schaffer developed and implemented modifications to the standard five-part load ticketing system specifically for the Texas GLO beach cleaning project. To ensure adequate beach cleaning, efforts were monitored carefully to verify: • complete debris removal • quality of screening operations • areas of sand screened • quantities of sand replaced to grade • depth of sand removed • hauling, reduction, and disposal of debris • security of stockpiles A total of 1.2 million cubic yards of sand was removed to a 12-inch depth, screened, replaced, and graded. Marine Debris: As the beach cleaning process neared completion, the process of removing marine debris began. The primary focus of this project consists of removing large submerged and semi-submerged debris (i.e. vessels, white goods, etc.) that posed a hazard to boats entering the waterways. Several thousand targets were identified over 350,000 acres of water in five major bays and the Gulf of Mexico. These target items were identified by side scan sonar and were reviewed by the state for historical significance. Neel chaffer placed monitors on boats to document the removal of approved items by description, photographs, and GPS coordinates during the removal/loading operation. Monitors issued load tickets and photographed vessels, cars, and debris at the marine extraction point, as material was transferred from boats to land based vehicles. Efforts were made to reconcile vessels with owners prior to disposal. Neel-Schaffer completed load tickets with volumes and photographed debris loads at the Debris Management Sites (DMS) and for vessels received at the Vessel Management Sites (VMS).
