I h.Planning Commission Chairman Kelley Orono Planning Commission Members <br />City Administrator Bernhardson <br />From: Michael P. Gaffron, Asst Planning & Zoning Administrator <br />Date: April 13, 1990 <br />Subject: #1517 Whitney MacMillan, 1560 Fox Street - <br />Conditional Use Permit - Public Hearing <br />Zoning District - RR-IB <br />Application - Request for conditional use permit for <br />reconstruction of existing artificial pond. <br />List of Exhibits <br />Exhibit A - <br />Exhibit B - <br />Exhibit C - <br />Exhibit D - <br />Exhibit E - <br />Discussion ■* <br />Application <br />Plat Map (see application #1516) <br />Property Owners List (see application #1516) <br />Survey (see application #1516) <br />Proposed Site/Grading Plan <br />As part of their proposed new residence construction after <br />the subdivision is approved, applicants wish to reconstruct and <br />slightly enlarge a small existing pond within proposed Lot 2, <br />Bloc)c 1. The existing pond is approximately 200' long and ranges <br />in width from 40'-90', with a total water surface area of about <br />1/4 acre. Applicants propose to rebuild this pond by dredging <br />it slightly deeper and increasing it to an average width of about <br />70'. <br />They would be constructing a stone wall approximately 2' <br />high along the outlet as a dam, and propose to continue <br />maintaining the elevation of the pond about 2' above the <br />artificial lake level by using their private well. The proposed <br />stone wall will be approximately 77' back from the shoreline of <br />the 8 acre Hake. <br />The applicants' proposal does not indicate how much dredge <br />spoil will be obtained, but staff would estimate that an area <br />approximately 70'x220'x3' deep will be excavated, resulting in <br />approximately 1,700 cubic yards of dredge spoil. Absent any <br />proposal to use that dredge spoil in some other location on the <br />property, staff would expect that this material will be trucked <br />off the property. <br />The City Engineer reviewed this application and had no <br />specific comments. Applicants are proposing a granite field <br />stone border and the pond will be underlined with a 30 mil poly <br />liner to miminize seepage and help maintain water in the pond.
