i9seREQUEST FOR COUNCIL ACTION ^ DATE: February 5, 1996 ^ ITEM NO. // Department Approval: Name Jeanne A. Mabusth Title Building & Zoning Administrator Administrator Reviewed:Agenda Section: Zoninsz Item Description: #2102 Howard and Lili McMillan, 1275 Lyman Avenue - Conditional Use PermitA^ariance - Resolution Zoning District:RR-IB (Property is not located within a Shoreland Overlay District). Lot area = Approximately 2 acres Application: Applicants seek approval of a conditional use permit and variance that would allow the excavation of a .12 acre pond within a designated wetland. Spoils from the excavation will be used to till a more graduated bank in place of the existing 1:1 bank that requires a retaining wall for stabilization. The tilling will be conducted within 26’ of the designated wetland. Brief Review of Application In the 197^ Orono Orchard Hiahland plat (Exhibit L), the final plat retlected the presence of a wetland in the southeast cornier. The w-etland was not described in angles and bearings on the final plat nor did the Citv obtain a flowage and conser\ation easement over the area. Recent wetland delineations revealed the exact location of the Type 3 wetland and a Type 1 wetland just 2-3’ to the west of the Type 3 wetland. Refer to Exhibit G, applicant’s surveyor has located the designated wetland (Type 3) on the sur\ey. The wetland is conticuous with the 30+ acre wetland and drainage system to the east and south of the subject property. Tlie wetland area to be altered is in a transitional area ot the wetland Purple I oosestrife is a dominant species within major portions of the wetland along with Reed Canary Grass along the outer margins of the wetland. Purple Loosestrile and Reed Canary Grass are invasive aquatic weeds that choke out the desirable native vegetation tissociated with a healthv, tliriving wetland. Applicants have provided photographs of the entire wetland area •md the'reviewing staff have completed an inspection of the property before the snowtall. I s hoped with the" excavation along the e.xterior of the wetland and the replanting with special wetland seed mixture that the Purple Loosestrife and Reed Canaiy Grass will be eliminated Note the Corps permit (Exhibit W) suggests the difiiculty of eliminating Purple Loosestnfe and recommends that either voung seedlings be removed from disturbed earth or applicants may have to resort to an approved weed killer. It is the desire of the applicants to rid the portion of wetland under their control completely of the invasive weed.
