This revised plan is generally acceptable, <br />however, approval is subject to the following conditions: <br /> <br />1) <br /> <br />Either a catchbasin should be added on the west side of the drive entrance to intercept runoff or <br />documentation needs to be provided showing that the overland flow is being transmitted to catchbasin <br />101 and not onto 139~ Lane (aCtually 140m Lane). <br /> <br />2) Elevation should be provided for the "grade break". <br /> <br />3) The north ditchline ofCR116 contains an existing sump area. This ditch should be regarded such that <br /> it flows to the east. <br /> <br />4) All stormwater piping associated with this development must be contained withhn drainage and utility <br /> easements. Currently MH 103 lies outside a drainage and utility easement. <br /> <br />5) <br /> <br />The minimum stormwater pipe size is 15 inch, other than catchbasin leads which are limited to 30 <br />feet. The plan proposes 12 inch pipe. The City will maintain the storm sewer only if it is constructed <br />to City standards and encumbered with a drainage and utility easement. <br /> <br />This commercial site is less. than one acre in area, and is not required to obtain a Lower Rum Pdver <br />WMO permit. However documentation must be provided to show that the sediments pond receiving <br />the runoff from this site contains sufficient storage volume to meet water quality requirements. <br /> <br />A final revised plan must be submitted prior to the commencement of site grading. <br /> <br />Sincerely, .,~ ,, ..', ., <br />City Engineer <br /> <br />S J/is <br /> <br /> <br />
