HARDCOVER RBGDLATIOIIS AND MORKSHEBT <br />A. EARDCOVER 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. HARDCOVER SETBACK ZONES - PERCENTAGE ALLOWED <br />I. 0-75': in the area within 75' of the lakeshore, No Hardcover is allowed <br />(00). <br />II. 75-2509: in the portion of <br />the lot located between 75' and 250' from the <br />( lake, 250 of that portion of the <br />lot may <br />be hardcovered. <br />1 III. 250-5001• in the portion <br />of the <br />lot locatod between 250' and 500' feet <br />from the lake 300 of that portion <br />L;: the <br />lot may be hardcovered. <br />IV. 500-1,0009: in the portion <br />of the <br />lot located between 500' and 1,000' feet <br />C from the lake 35+1 of that portion <br />of the <br />lot may be hardcovered. <br />NOTE: These regulations apple even if you <br />have a <br />lot that does not abut the lake but is <br />within a lakeshore zoning district. <br />C.
