in addition, the restrictor standpipe sho�ld be e�tended 6 <br />inches above the overflow elevation and capped. The cap <br />should re provide�i with a one inch vent hole. <br />Veaetated swales• <br />Spot elevations in the bottom of the swale shoulc. he given <br />at the head of the swale, at the swale ��tlet, r.nd at <br />approximately 5o foot intervals along the length of the <br />swale. <br />The swale construction notes and swale n��nting/seeding <br />requirements must be shown on both t��e landscaping plan and <br />the storm drainage plan. The landscape plan must be <br />submitted with the next set- of plans. <br />The seed application rate and the number of wetland plants <br />for the emergent swale should be indicated on the seed r:,ix <br />and wetland plant lists, as shown on sheet 6/l0. <br />There is some concern that the skale and even the outlet of <br />the oil/water separator may be below the high water level in <br />the creek at the swale discharge location. This situation, <br />if it exists, would adversely affect the function of both <br />the swale and the oil/water separator. The high water <br />elevation in the creek must be determined and the <br />information, including method of determination, presented in <br />the drainage calculations. <br />The outlet of the swale, in the wetland buffer area, sho�ld <br />be graded to provide a wide discharge area to the creek, <br />with side slopes no greater than 3:1. The swale side slopes <br />appear to exceed 3:1 as tlie swale nears the wetland buffer <br />area. <br />surface Pond Fencina Requirements: <br />Un�ess the applicant submits information showing that the <br />pond meets one of the conditions presented below, the pond <br />must be fenced. The location of the fencing and also the <br />location of the gates necessary to access the pond for <br />maintenance must be shown on the storm drainage plans. <br />All ponds with a maximum depth greater than three feet are <br />required to be fenced with a six foot high perimeter fence <br />unless one of the following conditions is met: <br />1) a l0 foot wide safety bench for every three feet of <br />design water depth and the side slopes of the pond are no <br />greater than 3:1 (H:V); or <br />
