• four 50 - acre site areas o see Figs 1 - 3 , below o two in western MS Sound and two in Eastern MS Sound o Geographic coordinates of site areas specified in table 1 below o Eight one - acre bounded pre - existing plots areas per site ▪ six of which contain established base reefs • Base reefs for 24 reef plots were created within one - acre bounded areas o Within six one - acre areas at each of the four sites o Base reefs were completed in two phases in spring and summer of 2024 ▪ One site was completed within each region of MS Sound during each phase ▪ Each base reef plot was constructed using 800 cubic yards of number 4 limestone gravel • To fulfill this bid , surficial enhancement of the designated reef plots will be conducted at a time TBD in spring - summer of 2026 ( TBD - April - July 2026 ) • The first augmentation of two plots per area occurred in late May 2025 o The same two plots ( plots 5 & 7 ) within each of the four sites were augmented during the May 2025 event • The time window for the second augmentation event will be arranged between contractee and contractor o Surficial enhancement of 2 of the 6 base reef plots ▪ For the same two plots ( plots 3 & 4 ) within each of the four sites ( See Figs . 4 - 5 below ) ▪ even dispersion of surficial enhancement material across the reef - plot areas ▪ 100 cubic yards of No . 57 limestone per reef plot ▪ The four other base reef plots at each site did not receive any enhancement during this event ▪ the two control plots lacking base reefs at each site did not receive any enhancement o GPS coordinates for individual plot - area boundaries are predetermined ▪ Geo - referenced side - scan profiles of base reef plots within base - reef plot areas are available from the contractee ( e . g ., Fig . 5b ). ▪ See Tables 1 and 2 below for GPS coordinates for lease areas and reef - plot area boundaries in NAD83 CRS • Or alternatively , in NAD 83 Mississippi State Plane feet ▪ See Figures 4 and 5 below for layout configurations of reef plot areas and reef plots within 50 - acre sites : • Plot areas ( one - acre ) arranged near perimeter of 50 - acre site areas o Areas of bare substrate interdigitate with reef - plots o Independence of treatments is thereby maintained
