The $19,000 is still there, and $22,750 was approved last night—total <br /> $41,750. Dredge cost estimated at 9 CY. There are 3309 CY to nominal <br /> depth and 4632 CY to overdredge depth=79 1CY or about 8000 CY, Total <br /> cost would be approximately$72000. <br /> Jim Hanks pointed out that the Town could cover 41,000 and how much <br /> additional is dredged would depend on how much money Save Popponesset Bay <br /> could donate. Kevin Harrington stated that we would have to discuss that in the <br /> future. Perry Ellis suggested dredging without the booster which should cost <br /> $4.55 per yard or approximately $36,000. save Popponesset Bay could then <br /> move the sand as desired to otherplaces on the spit. No conclusions were <br /> reached on how the dredging would be done, but all agreed to discuss the <br /> aiternatives farther. <br /> 1 Additional outer charnel markers will be needed to avoid problems for boaters. <br /> Needs review. <br /> sets of markers have been set, the last two will be set in calmer weather, <br /> and should be adequate. <br /> There was general discussion abort the condition ofthe channel, and some relief <br /> expressed at the understanding that the shallowest part of the channel, which i <br /> about . feet below mean low water, was only about 150feet long. The discussion <br /> centered on the `before dredge"survey done on 16 March which provided the <br /> measured depths in a contour chart fare. There is agreement by everyone that <br /> this channel must be dredged this upcoming season. <br /> l Dredging of the sand bar in the middle of l oppone set Bay. <br /> This proposal will be considered as a source of sand to nourish the Spit, and <br /> s a potential disposal site for Mashpee liver material. Core sample <br /> analysis is required to determine the characteristics of the material in <br /> Loi Tide Island", and how it changes with depth. It will be necessary to <br /> establish grain-size compatibility with the material on the spit, The Army <br /> Corps of Engineers Engineering Manual EM 1110-2-1618 s `'Coastal Inlet <br /> Hydraulics and Sedimentation" suggests that material In a flood tide delta <br /> is typically unsuitable for beach nourishment. (Page 2-24 discusses <br /> suitability of flood tide delta deposits as a sand resource. Although they <br /> cover a broad area, they tend to be thin layers of sand with a high silt <br /> content.) <br /> Kevin Harrington described their idea of ruining the spat and using the material o <br /> nourish the spat. He also mentioned that BSC had looked at the use off the Stenberg <br /> parcel, .dim Hanks pointed out that that site was not available according to Town <br /> CounseL Devin also introduced the idea oftreating a hole along the spit,pumping <br /> Page 2 of <br />
