e. Point source discharges to the stream and aesociated <br />wetlands muet be avoided. Techniques that result in <br />diapersed discharge should be utilized, such as <br />diepersion trenches or buried perforated pipe located <br />at the edge of the wetlend or stream buffer edge. <br />Detention and e wetpond ere required per City Design <br />Standards for thia siYe. <br />e. No stormwater facilities, including detention <br />fecilities or wetponde, may be loceted inside wetland <br />, or stream bufier arees. Wetlande may not be ueed for <br />� detentton of atormwater. <br />b. The proposed wetpond deslgn ehows the wetpond <br />outletting to a privete gress awale. The swale area <br />muet elsc be dediceted to the City. As en elternative, <br />the discliarge from the outlet could be pipAd to the <br />adge of the Native Crowth Protect!^� �ree (with <br />rppropriate energy dissipatlon et the �. •tl with <br />an eesement yranted to the City. <br />c. Rockeries ere not elluwed in the u.. .,- end <br />construction of wetponds. Per City atandards, Sf the <br />side slopes of the wetpond will be greeter the� 7:1 <br />(N:V), retaining wells must be provided. <br />d. The first cell of the vetpond must be eccesslble for <br />removal of eccumuleted sediment. City etanderda call <br />for e 15 foot wide gravel access road at a meximum <br />slope of 6:1. The volume of water that the eccess road <br />displaces in the wetpond muat be eccounted for. <br />e. The eccesa road to the wetpond, and therefore the width <br />of the eree Aediceted to the Clty, must be e minimum of <br />15 !eet wide. <br />f. The inlet and outlet structures to the wetpond must be <br />designed so that ell stormflow is forced to travel the <br />full length of thn wetpond. The efPective length [o <br />width ratio �t ^_he wetpond must be a minimum of 7:1. <br />Thie retio cen �e obtained through the use of bafFles <br />in the wetpond. <br />g. Wetpond and detention calculations are necessary to <br />determine vhether or not the proposed wetpond is large <br />enough to meet City standards. Without thase <br />calculetions, it is impossible to determine whether or <br />not adequate spece has been left for the wetpand. <br />h. The erea in the pond dedicated to vetland plantin,s <br />must havt b�etwe^n 6" and 12" of perr�ensnt aater depth. <br />This eree nuat ei' ir be 70t of the surface aree of the <br />pond, or 60k of .ne required purmanent atorage voluma <br />!n the poi,C, depending upon which City wetpond standerd <br />(/420-A �:1- 0) is chosen. <br />B. Seesonal limitetions will be pleced on lend alteration <br />activities due to the prozimity ot tha aite to an <br />envlronmentally sensitive aree.
