 The pit will be deep and expose the underlying Vashon Aquifer.The flow from this exposed aquifer (estimated at approximately 6.5 million gallons per day) will be directed down a man made ditch to Sequalitchew Creek with a flow eight times that of present Sequalitchew Creek.The dewatering of the aquifer will lower the groundwater level in the vicinity by as much as , thereby draining nearby Edmonds Marsh, a Class I wetland.
