7, Waterwgys hnprovement Plan and Dre&ing.Perrmks—Jim Hanks <br /> Jim Hanks reported that Fd Baker had discovered a potential site while talking with Torn <br /> udala. It is on Dots 5.and 6 on Page 95 of the.Assessor's naps, and it.has.two substantial <br /> kettle holes on the site. It is on the west side of great beck Road South just opposite <br /> Harry L esRosiers memorial.- Jing Harks has.talked to Eric-Smith, who.provided some <br /> pictures of the site with contour lines superimposed. Jfin has also done some calculations, <br /> and.concluded that by using the two kettle holes.as one de-watering-pit,.with the top <br /> running around the -foot contour,the -acre site would allow a pit that would hold 79 <br /> acre-feet of slurry. The-problem is if you-don't.line the.pity where is the salt going-to go <br /> Jim showed a water table contour map and stated that the fluid would flow, assuming a <br /> homogeneous.deposit of sand,perpendicular to-the.contour lines on-the.water table reap. <br /> He also stated that a lot of study would have to go into that issue to determine an acuate <br /> prediction of flow and-.the potential impact on the.potable groundwater in the.area. The <br /> people on River Road all have well water instead of Town water. <br /> The dredge pipes.could be.run under Great Neck Road in conduits, and the.dredge and <br /> discharge pipes run down the path in Harry DesRosiers memorial area to the river with <br /> ramal impact on that conservation-land. They could run over the.marsh on a structure <br /> that could thea be made into a canoe kayak landing after the project is completed. <br /> Jim also.said that he and Herb were-planning to-meet with-Jack Fitzsimons and El,,Iiot <br /> Rosenberg to discuss this idea further on Friday November 'h. <br /> Ed Baker expressed concern that by seeking such a large area we may risk getting the <br /> Conservation Commission to think negatively about it. He still favors a phased operation <br /> for doing the dredging. Ee-thinks.the northern most depression would-present.less risk of <br /> well contamination. <br /> Jim Hanks pointed put that nothing-is.cast.in.concrete.at.this point,.and that all.options <br /> 0 <br /> should be investigated rather than lint our selves prematurely. <br /> when it comes.to restoration we have at lei two alternatives; make a pond that may <br /> convert to a fresh water marsh, or grasslands as favored by Chuckle green to improve deer <br /> habitat. There are probably many others, and.w ,should be striving to achieve something <br /> that would appeal to the Conservation Commission. <br /> Jiro Hanks-stated that he went to.a presentation by Deerin.Babb-Brott of CZM to the <br /> Falmouth Board of Selectmen on the State project to re-activate the former dumping site in <br /> Buzzards Bay. They are about to issue a draft Environmental Impact,Report IR .ire a <br /> couple of mouths, and after review and revision, will issue a final EIR. Rick York <br /> questioned whether it was-too.far to transport.the material, and Jim Hanks-pointed.out that <br /> since we don't have a handle on costs,we couldn't tell yet. <br /> Page 3 Gf4 <br />
