t <br />C r RMOUTI MORIKSHRET 1 <br />A. RARDCOVER ORDINANCE - In 1975, the Orono City Council adopted an ordinance limiting <br />the percentage of lot 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 shown that sediments, oils, and debris carried into the lake <br />from highly urbanized areas have a detrimental impact on the quality of water in the <br />lake. The intent of Orono's ordinance is to ensure that rainfall run-off will be <br />cleansed by filtering through grassed or vegetated yard areas before entering the <br />lake. <br />B. RARDCOVER SETBACK ZONES - PERCENTAGE ALLOWED <br />I. 0-75's in the area within 75' of the lakcahore, No Hardcover is allowed <br />(00). <br />-- -- <br />II. 75-250's in the portion of the lot located between 75' and 250' from the <br />lake, M of that portion of the lot may be hardcovered. <br />III. 250-5001s in the portion of the lot located between 250' and 5001feet <br />from the lake 300 of that portion of the lot may be hardcovered. <br />IV. 500-1,0009s in the portion of the lot located between 500' and 1,000' feet <br />from the lake M of that portion of :;,e lot may be hardcovered. <br />NOTE: These regulations apply even if you have a lot that does not abut the lake but is <br />within a lakeshore soning district. <br />C.
