REGULATIONS AND MORICSHEET <br />A. RARDCOVER ORDINANCE - <br />In 1975, the Orono City Council adopted an ordinance lir.4'-in 9 <br />the percentage of lot <br />area that can be covered with impervious surfaces ("hardcover") <br />such as roofs, driveways, sidewalks, etc. on properties located within 1,000 feet of <br />a lake. Studies have <br />shown that sediments, oils, and debris carried into the lake <br />from highly urbanized <br />areas have a detrimental impact on the quality of water in the <br />lake.
