HARDCOVER REGULATIONS AND WORRSHEET _ <br />A. HARDCOVER 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, aidewalks, 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. HARDCOVER SETBACK ZONES - PERCENTAGE ALLOWED <br />1. 0-75': in the area within 75' of the lakeshore, No 9ardcover is allowed <br />(01). -- -- <br />II. 75-2500: in the portion of the lot located between 75' and 250' from the <br />lake, 251 of that portion of the lot may be hardcovered. <br />III. 250-5001: in the r- rtion of the lot located between 250' and 500' feet <br />from the lake 301 of that rortion of the lot may be hardcovered. <br />IV. 500-1,0001: in the portion of the lot located between 500' and 1,000, feet <br />from the lake 35 % of that portion of the 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.zoning district. <br />C.
