EXHIBIT A <br />RICE CREEK WATERSHED WATER RESOURCES MANAGEMENT PLAN <br />DR A 17 CITY COMMENTS <br />1. ITEM <br />Management implementation strategy concerning water quantity (Page V-15) <br />PROBLEM <br />The Management Plan states "The local water management plan must <br />demonstrate that for a 100-year return frequency rainfall event, the rate <br />of storm water runoff leaving the municipality will not exceed the rate <br />storm water runoff leaves the municipality in its undeveloped condition." <br />This strategy creates a much higher goal than the current strategy of <br />required new development to have storm water runoff rates equal to the <br />existing condition. <br />Developed municipalities will have difficulty attaining this goal in a cost <br />effective and environmentally sound manner. Municipalities will need to <br />purchase additional land for ponding. <br />Trying to reduce outflow rates from a muneipaldty is a laudable idea, but it <br />' is too idealistic. <br />CITY POSITION <br />The management implementation strategy concerning water quantity should <br />require cities to maintain the existing storm water runoff rates as <br />established per the TR-20 model results referred to on Page III-26 of the <br />Management Plan. New developments and redevelopments shall have storm <br />water runoff rates equal to the existing condition. If opportunities are <br />available, redevelopments shall have storm water runoff rates equal to <br />undeveloped condition. <br />The problem statement in the plan should be more detailed and stated more <br />concisely. The plan shall then recommend a solution to the identified <br />problems. <br />2. ITEM <br />Water quality protection and pretreatment approach (Page V-18). <br />PROBLEM <br />Water quality control and/or pretreatment objectives are too stringent. It <br />will be difficult to achieve from an effective environmentally and fiscally <br />sound approach. <br />
