. ~ .. -2- by excess stormwater drainage and the attendant inflow of sediment and nutrients. At the same time, that potential damage must be balanced, as the report states, by the need for naturally-occurring stormwater to maintain the level of surface waters. We applaud the fact that the plan provides areas where stormwater can slowly percolate into the water table. The plan itself illustrates the need to replenish ground water. Nine Mile Creek, according to the report, has the high water ~uality the tests reveal in large part due to the fact that a portion of its flow comes from ground water. Were it nothing more than surface water drainage, its sediment and nutrient load would be much closer to that in the Cincinnati example. We were concerned chiefly about two issues: that the majority of the holding basins appeared to be in the parks and that the report did not recommend city action to preserve natural wetland areas by controlling development. The surface-water cleansing action of wetlands is well documented, and ground water recharge from natural wetlands is important to maintain the water table and the consequent flow of relatively clean ground water into surface water. Les Proper has been kind enough to provide us with the Barr report which indicates the time periods that the ponding is projected to remain in the parks, and we have concluded that if the Park Board is satisfied, we are, too, although we hope actual experience will be closely monitored so that we do not discover that the parks are unusable for long periods of time. It is our understanding that you are now considering developing and adopting a wetlands management ordinance which would give the City
