Request for Council Actiori continued Page 2 November 6, 1996 #218? Charles L Kramer, 2990 Somerset Lane to ensure adequate distance is maintained from wetland area The engineer's report recommends a 26' setback This is a setback required for all land alterations adjacent to protected wetlands of the City Staff recommends that the protected wetland within the northern portions of Lot 2 be staked in the field to ensure the minimum 26’ setback from proposed fill (review Exhibit G) Septic test sites on Lots 2, 3 and alternate on 4 must be staked prior to any earth movement. Staff found the wetland located in the northwest comer of the property to be severely degraded and would not classify the wetland as a Type 7. Creation of open water area within the low retention area would create an upgraded wetland along with benefit to varied species of wildlife. The wetland located within the street yard is of more concern for staff The wetland has been classified as a "high quality Hardwood swamp", review Exhibit K. Review Exhibit J, the DNR informatioii lists several species of wildlife that benefit from this type of wetland John Smyth, an aquatic specialist at Bonestroo, has been asked to review the proposal He advises that this is a true Type 7 wetland and shows no sign of degradation and that these are rare and should be protected The creation of an open water area would not raise the value of this wetland There are several mature trees within the wetland. Based on the design specs provided in the alteration plaa Exhibit G, it would appear that the majority of trees would be eliminated. Staff has discussed this concern with Mark Gronberg and he noted that it is applicant's intention to attempt to save the trees with the creation of an irregular pond for the purpose of encouraging other forms of wildlife Planning Commission Recommendation Based on Smyth's strong recommendation to save this wetland, the Planning Commission recommended against any dredging or disturbance of the "Hardwood Swamp" in the southeast corner of applicant's property They approved the dredging of an open water area in the wetland at the northwest corner and placing of spoils on Lot 3 only - no filling is approved within Lot 2 Prior to the land alteration, the wetland on Lot 3 must be staked and septic systems on Lots 3 and 4 fenced off from construction vehicles. It shall be applicant's responsibility to maintain adequate erosion control until ground cover is restored to entire disturbed area Applicant to provide detail on final slopes of banks of the pond. Per MCWD permit, the wetland plantings are to be seeded at a minimum WA' width around the edges of the pond. Applicant is encouraged to plant appropriate species of tiees within Hardwood swamp at southeast corner of property and, if desired, remove the buckthorn stand between road and wetland but this must be conducted under close supervision and direction of Orono staff I
