Article 34
<br /> To see if the Town will vote to amend Article VII,Groundwater Protection District,of the Zoning Bylaw
<br /> by replacing the current language of Section 174-80.F.with the following,indicating that such uses are
<br /> allowed in the District:
<br /> �i
<br /> "F.Land uses which result in the rendering impervious of no more than fifteen percent(15%)or two
<br /> thousand five hundred(2,500)square feet of any lot,whichever is greater,except as permitted under
<br /> Section 174-82."
<br /> and by replacing the current language of Subsection 174-81.N.with the following,indicating that such uses
<br /> are prohibited in the District:
<br /> "N.Land uses which result in the rendering impervious of more than fifteen percent(15%)or two thousand
<br /> five hundred(2,500)square feet of any lot,whichever is greater,except as permitted under Section 174-
<br /> 82."
<br /> and by amending Subsection 172.82.A.by replacing the first four lines,up to the phrase"may require:",
<br /> with the following:
<br /> "A.Within the Groundwater Protection District,unless prohibited by a specific provision of Article VI,the
<br /> following uses may be permitted by the Planning Board under any special permit issued by that Board,or
<br /> otherwise by a special permit from the Zoning Board of Appeals following the procedures specified in
<br /> Subsection B.below,under such conditions as each Board,acting as the permitting authority,may
<br /> require:"
<br /> and by adding a new Subsection 174.82.A.(4)as follows:
<br /> "(4)The rendering impervious of greater than fifteen percent(15%)or two thousand five hundred(2,500)
<br /> square feet of any lot,whichever is greater,provided that a system of stormwater management and
<br /> artificial recharge of precipitation is developed which is designed to:prevent untreated discharges to
<br /> wetlands and surface waters,preserve hydrologic conditions that closely resemble pre-development
<br /> conditions,reduce or prevent flooding by managing the peak discharges and volumes of runoff,minimize
<br /> erosion and sedimentation,not result in significant degradation of groundwater,reduce suspended solids
<br /> and other pollutants to improve water quality and provide increased protection of sensitive natural
<br /> resources.
<br /> These standards may be met using the following or similar best management practices:
<br /> For lots occupied,or proposed to be occupied,by single or two-family residences,recharge shall be
<br /> attained through site design that incorporates natural drainage patterns and vegetation in order to maintain
<br /> pre-development stormwater patterns and water quality to the greatest extent possible. Stormwater runoff
<br /> from rooftops,driveways and other impervious surfaces shall be routed through grassed water quality
<br /> swales,as sheet flow over lawn areas or to constructed stormwater wetlands,sand filters,organic filters and
<br /> /or similar systems capable of removing nitrogen from stormwater.
<br /> For lots occupied or proposed to be occupied by other uses,a stormwater management plan shall be
<br /> developed which provides for the artificial recharge of precipitation to groundwater through site design that
<br /> incorporates natural drainage patterns and vegetation and through the use of constructed(stormwater)
<br /> wetlands,wet(retention)ponds,water quality swales,sand filters,organic filters or similar site-appropriate
<br /> best management practices capable of removing nitrogen and other contaminants from stormwater and
<br /> meeting the Stormwater Management Standards and technical guidance contained in the Massachusetts
<br /> Department of Environmental Protection's Stormwater Management Handbook,Volumes 1 and 2,dated
<br /> March 1997,for the type of use proposed and the soil types present on the site. Such runoff shall not be
<br /> discharged directly to rivers, streams,other surface water bodies,wetlands or vernal pools. Dry wells shall j
<br /> be prohibited. Except when used for roof runoff from non-galvanized roofs,all such wetlands,ponds,
