<br /> a.nd I am now finishing my Ph.D. ti-ere working directly for ":'A on air pollution.
<br /> So, I have been involved in site pl%nning for approximately twelve years and I
<br /> have been involved in this project since its very beginning aperoximately six or
<br /> seven years ago. Again, all approvals as you can see on these plans were 1974--
<br /> 1975, which, of course, pre-d.^.ted the Indian s>>it. Basically, what we have here
<br /> is a very unique site as c:a.rle has mentioned of sloping areas that actually come
<br /> down to the river. There is a small plateau area up on top and then there are
<br /> also various hilly areas around 'the site. Basically, what we have is Quinaquisset
<br /> Avenue coming down as the main road with a single spine road coming in. We have
<br /> arranged buildings around the spine road on either side of it to try to minimize
<br /> the amount of disruption that we actually do to the natural vegetation and yet
<br /> still make the grades themselves work on the hilly side. Essentially what we
<br /> have here is along the top of the road -- the road itself is approximate elevation
<br /> thirty to elevation 28 and it varies back and forth with the first floor of the
<br /> building essentially fronting on that particular spine road and they also have
<br /> walk-out basements on the backside. So, essentially, you have the first floor
<br /> coming up on the roadway, parking areas and then you have a walk-out basement on
<br /> the bottom. Again, this is the type of hillside building that we try to do to
<br /> minimize the amount of vegetation disruption. These areas up in here are higher
<br /> than the read itself and we have to do signific-nt grading around here to actually
<br /> make the ,trades work. The buildings, themselves, as you probably cannot tell from
<br /> those pi=ns alone, are essentially a mix of flats, town houses and over and under
<br /> units th=.t we have planned at this particular point.
<br /> The reason for the Notice of Tn"ent a-ain is, as you well know under the General
<br /> -
<br /> La.wS 131 , Section -'0, that we are 'v7itnin the C-,nservaticn ':o'RS:issiori s jurisdic-
<br /> tion --anytime we do any type of alteration of drainage patterns, building or any
<br /> type of construction within 100 feet of the wetland. What we have shown here in
<br /> the aqua color (referring to the plan) is essentially the Santuit River itself as
<br /> defined by the survey that was done by Phil Holmes back in 1974. � e are looking
<br /> at and anticipating the type of construction here... We have more or.less planned
<br /> in an ad hoc type of program for eros'_on control and sedimentation control. We
<br /> feel this is very important, particularly during the construction stages, to pre-
<br /> serve the environmental character of the area and not, essentially, add a lot of
<br /> filtztl0:
<br /> erosion, etc. to �o riown into the river and on into the marsh land.
<br /> 'chat we plan to do is essentially state out a snow fence or something similar to
<br /> r, algin,>. ap. roxima.te elevation 0 �•
<br /> that 1 (tr.at runs next to the marsh I'll define
<br /> anywhere rom 20 feet to 50 feet -- probably a minimum of about 10 feet down in
<br /> through here of the proximity to the ed>e of the marsh itself. In front of that
<br /> snow fence, as a - ysical to t.^,e actual conz:tr:lct`.on, we also, if neces-
<br /> sary, in particular steep grade areas, would stake hay bales as an ad hoc more or
<br /> less se-_`_n^nt=tion control. This has a twofold purpose, iur..ber 1 , the people
<br /> that are act',;ally building the units themselves have an actual physical barrier
<br /> tha+ they can actually see when they are going to at near the marsh land, etc.
<br /> "fat they are no.t to cross and phvsical].j' can't cross without, of course, break-
<br /> ing the fence. The second aspect of this is to create the sedimentation barrier
<br /> that will essentially take care of any cif the possible erosion that may take
<br /> place and, again, temporary erosion during the construction phases. The third
<br /> wart that We would like to mention is as soon as the construction is finished,
<br /> rye crass for
<br /> we will ,-zo bac: in with pl=_niin.gs, Wlt."; grass (prOoabl'i a r. ir:r
<br /> "he I _rs" setH7 and then the stron,_er root strpct7res for areas. ..nv of
<br /> you that have gone there new, you will note that ".:is entire area along this
<br /> front right now is pretty sparse vegetation. There are ver.7 severe areas of
<br /> erosion that h=:.ve occurred in this area because cf essentially no ve_etation to
