New Dredging <br /> Phase I - 1997 Popponesset Bay Feasibility Analysis <br /> • Preliminary step - Contract with Aubrey Consulting using their computer model <br /> of Popponesset Bay flushing to evaluate proposed dredging scenarios using 1994 data. If <br /> this is done in the next three weeks, it could potentially eliminate some very expensive <br /> dredging proposals. We feel this$999 study will be a major help in estimating the <br /> effectiveness and cost of several dredging alternatives. <br /> • Develop data needed to support the permitting process and to help us learn what <br /> dredging will have a beneficial effect on the Bay system. <br /> • Do Hydrographic analysis of all of bay - bathymetry - feeds flushing analysis and <br /> tells how much material should be removed. <br /> • Develop Sediment Analysis plan for approval by DEP and ACOE <br /> • Do part of sediment analysis - Grain Size and Chemical Analysis of Mashpee <br /> River and Main Channel to determine what the spoils disposal options are. Needed to <br /> accurately estimate a cost. <br /> • Conduct Flushing Analysis using up to date data and recommended dredging <br /> scenarios. <br /> • Perfonn Cost Trade off analysis of those scenarios that produce a beneficial <br /> effect. <br /> • Recommend course of action and budget required to Board of Selectmen. <br /> Phase II - Permitting 1998-1999 <br /> • Town Meeting Decide on funding <br /> • Perform additional sediment analysis in other areas as needed. <br /> • Prepare Permit Applications using Phase I data <br /> • Secure spoils disposal agreements <br /> • Submit plans & modify as needed to secure pen-nits <br /> • Finalize estimates of dredging costs by increments <br /> • Receive all Permits <br /> Phase III - Dredging <br /> • Dredge Main channel of Popponesset and Mashpee River Winter 1999-2000 <br /> and Conduct Post Dredging in <br /> Survey <br /> g g Y <br /> • Dredge Ockway Bay Winter 2000-2001 <br /> and Conduct Post Dredging in Survey <br /> g g Y <br /> Page 2 <br />
