Abstract : By analyzing the organic enrichment and sediment grain sizes found in each of the five ZSF's 4(Zones of Siting Feasibility) selected for Phase I of the Puget Sound Dredge Disposal Analysis program, the 'depositional' areas of lowest energy within those ZSF's were delineated. Major findings include: 1) All five ZSF's contained areas of significantly elevated organics and small sediment grain sizes. 2) The preliminary sites within the ZSF's in Commencement Bay, inner Elliott Bay, Fourmile Rock, an Port Gardner contained high percentages of clay and organic elevated in excess of the 95% CI, indicating they were all areas of low current energy where fine sediments deposit naturally. 3) Nearly the entire ZSF in Saratoga Passage had levels of organics in excess of the 1.96 SND in addition to small grain size and high clay content. Therefore, the entire area is considered very depositional in nature. 4) The outer preliminary site within commencement Bay appears to be slightly more depositional than the inner preliminary site. 5) Although nearly all of Port Gardner appears to be a low energy area, the preliminary site in central Port Gardner appears more depositional than the site near the southern shoreline.
