Sector 3 Beach & Dune Restoration Project Attachment I to Change Order No . I Sieve a mean grain size of 0 . 36mm with an available volume of approximately 625 , 000 cubic yards of sand . The Ranch Road Lake Mine "RR Processed" sand proposed to be placed on the beach is characterized by poorly sorted medium- grained sand with 1 . 48 % gravel , 0 . 15 % fines (4200 Sieve) a mean grain size of 0 . 51mm a median grain size of 0 . 43mm 42 . 35 % carbonate, 0 . 81 % organics and a wet Munsell color of light gray ( IOYR 7/ 1 ) . The "in situ" material in the Fischer 86t1i Mine is characterized by well sorted, fine - grained sand with an average of 5 . 67 % fines (4200 Sieve) a mean grain size of 0 . 32mm with a volume of approximately 4 9 million cubic yards of material . The Fischer 86t1i Mine "processed sand " proposed to be placed on the beach is characterized by poorly sorted , fine - grained sand with 1 . 88 % gravel 1 . 48 % fines (4200 Sieve) , a mean grain size of 0 . 39mm , 1. 2 . 57 % carbonate , 0 . 69 % organic and a dry Munsell color of white ( 10YR 8 / 1 ) .

Standard of Acceptance for Sand Only beach compatible fill shall be placed on the beach. Standards of compatibility are defined by the Florida Department of Environmental Protection " Rules and Procedures for Application for Coastal Construction Permits " Chapter 62B -41 . 007 (2 ) j . These rules are commonly known as the " Sand Rule " and can be found at : http : //www. dep . state . fl . us/legal /R-Liles/beach/62b -4I . pd Consistent with these rules , sand fill to be placed on the beach shall conform to the parameters identified in Table 2 .

The CONTRACTOR shall place sand on the beach consistent with their bid . On average the testing performed at the mine and on the beach shall show that the mean grain size and overfill factor are equivalent to or better than what was identified with the CONTRACTOR ' s bid If the material is deemed unacceptable by the COUNTY , ENGINEER or FDEP the CONTRACTOR is to stop placing beach sand material on the Page 17 of 26 March 16, 2010
