Conservation Commission <br /> August 2 , 1988 <br /> Page 8. <br /> Mr. Cauley stated this was minor in the overall scheme of things and could be rade <br /> part of the order of conditions to restore that. <br /> Nor. Kirrane stated if that dwelling i completed, that bank is goinghave to be <br /> addressed. <br /> A letter from Charles Rowley was read stating agreement with the concept shown on <br /> the sketch but expressing concern with the size of the leaching pits with respect <br /> to the existing road grades, tenth of road which drains to this point and the <br /> impervious driveway and roof surfaces which will also contribute runoff, e <br /> stated there should be assurance from Arrow Engineering in the form of runoff <br /> calculation-s that the two leaching pits are adequately designed to handle the <br /> runoff volume. Normally, subdivision road drainage in the Town of Mashpee is <br /> designed to handle the volume of runoff generated from a to ,year evert over a 90 <br /> minute duration. In this instance, he would recommend a calculation used on a <br /> 25 year storm over a 90 minute duration to provide extra storage for storm water <br /> as there is no place for the excess water other than the surface of the street or <br /> the Mashpee River. This cannot be determined if either of the storm conditions have <br /> been accounted for by the level of data given. <br /> Mr. Rowley further stated Ernest Virgilio has expressed other concerns as well that <br /> he felt have not been met. <br /> Mr, Tirane stated it would have been nice if M . Virgilio had supplied them with a <br /> letter of his concerns. <br /> Mrs. Simmons asked if they had contacted DEQE and had they made any comments? <br /> Mr. au ley stated he contacted Leld n Langley and his only mO ment was he wanted to <br /> see a solution satisfactory to everyone. Lisa is to call hire. <br /> Mrs. Jacobson asked who is responsible for maintenance. Mr. Cauley stated the norm, <br /> after 51-55% of subdivision is sold out, the burden of maintenance goes to the home- <br /> owners, <br /> Mrs. Simmons asked what type of maintenance schedule wasp p r osed <br /> Mr. Cawley stated he was not asked to do one, but stated he would. <br /> Mrs. Simmons stated none of this addresses the River itself and asked if that would <br /> be dome in another part, re the monies to be applied* <br /> Mr. Ki r ne stated that was presented earlier and no definitive response was received <br /> from the Commission. Information in the offer previously made still stands. They <br /> are also concerned in solving the zoning issue that they proceed as fair as the Con- <br /> servation issue is concerned with the construction of the dwelling on Lot 14 which <br /> was the subject of an earlier order of Conditions. <br /> Ms Behrman stated at the previous hearing and discussion of what to do about the river <br /> and the situation a the mill pond, we did have comments from the herring warden and <br /> he did have some serious concerns about the adequacy and there was an impasse. She <br /> feels his client should discuss this further with the Herring garden. <br /> Mr. Iirrne .stated he recollects that Mr* Virgilio was proposing to do a lot of that <br /> work by hand with his staff and his client was going to contribute. <br /> Ms Behr an stated he had serious concerns as to the adequacy of the payment. � <br />
