Mr. Dave Nyberg 2- May 13, 1997 l D ' NURP requirements are often included with rate control requirements as described above. Complete design information for NURP ponds can be obtained from the RCWD District pe+diX Engineer. An addition to the city plan requiring water quality treatment equivalent to NURP guidelines for stormwater discharges for any new development will be required. ��im SS Easements. Similar to the requirements for floodplain management, the RCWD requires C - 0) protective easements be provided for all stormwater management provisions associated with development. A statement to this effect will need to be added to the plan. Maintenance. The city should identify in the plan a maintenance program for stormwater ponds with minimum inspection and cleaning frequency specified. WETLAND MANAGEMENT SGt� ia� s� Wetland Conservation Act. The plan contains no reference to the Minnesota Wetland (Isl� Conservation Act (WCA). The RCWD currently serves as the Local Government Unit (LGU) for administering the WCA within the city limits of Centerville and anticipates continuing in that role in the future. This should be acknowledged in the city's plan. .Sed7en 5.6 RCWD Wetland Policy. The watershed district also has its own wetland management plan which encompasses a broader range of wetland alteration activities which need to be included in the city's plan. Detailed information outlining the RCWD wetland policy can be found in section 5 of the RCWD management plan and can be obtained at the District office or the office of the district engineer These policies need to be incorporated into the plan. _,e,4(m 5.6 Easements.

(e MDNR protected waters and wetlands and the importance of the Ordinary High Water (OHW) level, there should be a table included in the plan which identifies the elevation of the OHW for each basin (if available). Also, an inclusion should be made identifying the contact person within the MDNR to whom responsibility for water/wetland management falls. Similar references should be provided for the USCOE. SHORELAND MANAGEMENT ,die„ S -8' The model ordinance included in the plan appendix is sufficient for RCWD purposes. However, we would suggest that Clearwater Creek be included as a watercourse subject to 7 the provisions of the shoreland ordinance. Additionally, a date for adoption of the ordinance Ivn or schedule of revisions and implementation should be included to an administrative improvements plan. GENERAL COMMENTS 52e�lan s.7 Permitting. The city's plan states that the "RCWD shall continue to require permits for construction projects occurring in Centerville." However, there is no mention of wetland alteration or other District - regulated activities not limited to construction. The city needs to clearly specify whether the District is to continue to administer all water resources pemlitting responsibilities.
