It Is..Assumed.by the project applicants'the waiver is still in effect today. <br /> The storm water runoff from all areas except the wood storage and yard wastes composting <br /> area-will drain to anon-site retention pond.The retention pond will be sized to contain 200 <br /> percent ofithe computed volume of runoff from the 166 yeiaiir/24-hour storm.
