Zoning File #2294 October 17, 1997 Page 7 of 9 4 As a result of Items I, 2, and 3, the watershed area draining to the southerly ravine will decrease, and this is anticipated (and must be confirmed) to result in less runoff and slower rates of rxinoff to that southern ravine. 5 TTie stormwater pond in Lot 1 will store and release stormsvater to the northerly ravine at a ^-Hived flow rate from the current condition, even though volumes will be greater due to the added runoff from development. The stormwater pond is positioned in a location that could potentially be_^anded if City development of the tax forfeit park property ever required additional stormwater ponding. 6 The City will gain drainage and utility easements over the portions of the rame within the proposed subdivision, giving the City the ability to manage those ravines as part of the City's comprehensive stormwater plan.
