+ t � , Ms. Barbara Walther Ms. Becky Houdek � RECEIVED Mr. John Smyth January 15,2010 ,IAN 18 2010 Page 7 CITY OF ORONO The mitigation basin will be seeded with a BWSR W3 (Native Wet Prairie) seed m�at a rate of 10.0 PLS lbs/acre. Upland Buffer � The applicant will establish a wetland buffer along the west side of Mitigation Basin B. Approximately 0.58 acres (25,180 SF) of upland buffer will be established by removing the existing non-native vegetation and seeding the buffer area with a BWSR US (Native SE MN Mesic Tall-grass Prairie) seed mix at a rate of 15.0 PLS lbs/acre. Because the WCA only allows wetland credit for 25%of the total upland buffer area established with native,non- invasive vegetation,the applicant will receive 0.14 acres (6,295 SF) of wetland credit for the additional upland buffer area. � WETLAND MONITORING PLAN Miti�ation Objective Goa1s ➢ Utilize excess wetland creation and upland buffer credits that were created as a part of the 2009 wetland perxnit and grading activities. The applicant will apply 2,975 SF(75% of 3,967 SF) of wetland creation area and 2,082 SF (25%of 8,328 SF) of upland buffer area toward the 2010 pond expansion project. ➢ Create at least 5,366 SF (75%of 7,154 SF) of Type 2,fresh(wet)meadow wetland on- site, adjacent to Mitigation Basin. ➢ Establish at least 6,259 SF (25% of 25,180 SF) of native upland buffer adjacent to Mitigation Basin B. Miti�;ation Monitoring ' The applicant will be responsible for completing the annual monitoring events of the project site to ensure that the wetland basins exhibit wetland characteristics as proposed in the mitigation plan. Annual reports will be submitted to the MCWD for review anc�concurrence. Annual monitoring will continue for five (5) years or until the long-term success or failure of the Mitigation Plan can be established. The Mitigation Plan will be judged successful once permanent vegetation is established that meets the goals of the Mitigation Plan. Mitigation Plan failure will be determined if the above plan goals are not met or likely will not be met after five (5)years,provided abnormal climatic conditions have not prevented meeting the stated goals. Corrective actions will be made if the basins appear to not meet the objective goals.
