Mike McGrath: The location is at Maushop. Village. it is very similar to S moor Goldberg s intent. Basically. what we are trying to do is stop erosion at the base of the cliff, The top of the riprap is at elevation 14. The riprap will be placed on filter cloth. Where will be fill installed. We will install brush on on top of bluff. Are there any particular questions from theBoard? Pauline: The size of the toe stones, 2 to 3 ton, are not permitted. :fir. Brooks: We are the abutters to Maushop Village. The water is unreal, The cliffs are not washing. It is the water washina off the top of the village. 'There have been no drainage systems put in there in the past fifteen *r ea rs to my knowledge, ;then they started the new condominiums, we came here for hearing and asked [.hem to put, in the proper drainage to get rid of this water. The water now washing off the top in Maucshop Village is unreal and that is what is washing off the cliff. There are now some houses which were 30 Feet from the cliffs now only 10 feet from the cliff. If they build the riprap, 1 would like it to go from the Popponesset Inn across *, r property line and thea they can do whatever they want to. They can go all the way to South Cape. March Da.rdano of Rock Island #gid. : Presents three slides of the area to the Board. 'aulie: Mates that the hoard is very fam .lar with the area and that they have other p#ctures which were taken down there when D QE dial an on-site in e t on. Mr. uebler: 'today I am representingaushop Vile as the trustee of the village. When we met with you and DEQE on the site, we were asked to come up with some pro- posal. Phil Holmes and 1 went up and met with them. We talked about this design. 'here was quite a bit of time spent in deciding ghat type of design would place the least amount of impact in terms of wave deflection and dispensing energy as a ser- ious thorn and so forth. go this represents a ,point effort with DEQE. The reason 1 emphasize that is that if this committee recalls that last year we came and we got the order o Conditions from this committee to go .head and stabilize this bank at the sea level part of the bank, The Conservation Commission, dere In Mashpee, a DDr'oved it. auline: e didn t approve your plan, ;fie suggested pyramid of rocs at the base, 'fir. uebler; yes. And DEME did not, go along with this and issued a superseding offer. - It itas because of that that we gent, to DEQand asked thea to assist us in the design of the structure, For the record, I would like to say that I can't really disagree with our neighbors. The water run--off has been a serious problem. We put in what was required for new construction. We had a very serious rain storm and throughout the entire community of 14ashpee' there was flooding that had not been experienced for many, massy years, we have since gone back to our engin- eers and asked them to recalculate all of the surface ri-m-off water so that we can try and take steps to prevent this from happening again* Under normal rain conditions, we do not have anywhere nea;� the problem that we had that one particu- lar play.
