Approximately <<e -half of this site appears to drain towards Silver Lake and one-half south towards the stream that drains Silver Lake. There does not appear to be adequate drainage facilities in either direction to accommodate the increased rata and volume of storm water runoff that will result from this proposal. Therefore, an off -cite drainage analysis must be performed by the applicant to determine what off-site drainage improvements are needed to accommodate the increased runoff in a non -erodible, non -flooding manner.
