<br /> . EXHIBIT A <br /> RICE CREEK WATERSHED WATER RESOURCES MANAGEMENT PLAN <br /> 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 muncipality 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 111-26 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 approaoh (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 />
