-'ity of ITEM ~ 6.4. Memorandum iver TO: FROM: MAYOR AND CITY COUNCIL STEPHEN ROHLF, BUILDING AND ZONING ADMINISTRATOR DATE: SEPTEMBER 21, 1998 ~. SUBJECT: WETLAND CONSERVATION ACT DECISION - WCA 98-6 AND EASEMENT VACATION - CASE # EV 98-6 - JOHN LENZ John Lens is proposing to fill approximately 7,533 square feet of type II wetland to accommodate a building site. The proposed site is Lot 1, Block 1, Parkview Addition. A vicinity map is attached to this memo. Mr. Lenz is purchasing this lot from the city. Since the wetland in question is not in a shoreland area, the De Minimis area, or area that is exempt from replacement is 5,000 square feet for filling type II wetland. This means that, if Mr. Lenz's request is approved, out of the 7,533 square feet of wetland he proposes to fill, he will need to replace 2,533 square feet. The ratio for replacement in Sherbume County is 2 to 1, so Mr. Lenz will need to create a minimum of 5,066 square feet of wetland. Mr. Lenz is proposing a replacement wetland area of approximately 13,916 square feet, which includes a 15 foot vegetative buffer strip on its upland perimeter. The replacement wetland and buffer area will be graded at a maximum of a 5 to 1 slope. Approximately six inches to one foot of muck from an adjacent wetland will be placed on the bottom of the created wetland to help seal it and to provide aquatic vegetation seed. The city will monitor this wetland yearly to ensure its establishment is successful. On the attached site plan, the striped area shows the proposed location of the replacement wetland and buffer strip, and the southern most shaded area shows the area where wetland is proposed to be filled. An associated request is the vacation of two areas of drainage and utility easements on the property; both the northern and southern shaded areas on the attached site plan. The request to vacate the southern portion of drainage and utility easement is so wetland can be filled in this area to accommodate Mr. Lenz's proposed house. The northern area where drainage and utility easement is proposed to be vacated is to accommodate a garage. The drainage and utility easements on the property are larger than the actual wetlands. No wetland filling is associated with vacating the northern easement. Further, there is a relatively large wetland complex in this area. The vacation of either area of 13065 Orono Parkway · P.O.
