<br /> . <br /> . Quality control and/or pretreatment before all protected waters and <br /> wetlands is impractical. Present RCWD rules permit use of public wetlands <br /> as a method of pretreatment. <br /> CITY POSITION <br /> The RCWD plan should identify and prioritize which of the water resources <br /> are of greater publiC benefit. Sometimes it may be necessary to permit <br /> trade-offs to provide protection of a greater public benefit. Use of an <br /> existing wetland may be the most practical and cost effective method of <br /> pretreatment to protect the more significant resource a of downstream lake. <br /> The plan must be flexib!e to recognize and permit quality control and/or <br /> pretreatment methods which protect the most critical resource. <br /> 3. ITEM <br /> Overa!l management strategy of the Rice Creek trunk storm sewer system <br /> (Page V-5). <br /> PROBLEM <br /> The plan as submitted does not identify existing district trunk problems <br /> nor establish a program or commitment by the Rice Creek Watershed District <br /> . governors to correct and manage the problems. <br /> CITY POSITION <br /> a. The Rice Creek Watershed District Management Plan should use the TR-20 <br /> computer run on the existing development and projected year 2*OOO~water <br /> quantity conditions. Any development or redevelopment within the <br /> district would then be required to satisfy the existing condition in <br /> water quantity design. <br /> b. The plan should then specifically address the identified flooding, <br /> erosion, and quantity problems providing the time frame for identifying <br /> the most economical and cost effective solutions. <br /> c. The Rice Creek Watershed Management Plan must then identify the <br /> trunk system within the district (recommended out!ine attached). <br /> This trunk system then becomes the specific responsibility of the Rice <br /> Creek Watershed Board of Governors for correcting and managing in the <br /> plan. Provisions should be incorporated that prOVides for the district <br /> governors to coordinate and facilitate maintenance, repair, and <br /> construction of improvements for non-mainline trunk projects involving <br /> two or more muncipalities, if requested. <br /> 4.
