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 r.ainfal l 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's in the area within 75' of the lakeshore, No Hardcover is allowed <br />(01). <br />II. 75-250': in the portion of the lot located between 75' and 2::0' from the <br />lake, 251 of that portion of the lot may be hardcovered. <br />III. 250-5009: in the portion of the lot located between 250' and 500' feet <br />from the lake 300 of that portion of the lot may be hardco-ered. <br />IV. 500-1,000's in the portion of the lot located be sr. 500' and 1,000' feet <br />from the lake 350 of that portion of the lot may be ha gyred. <br />NOTE: These regulations apply even if you have a lot that does abut the lake but is <br />within a lakeshore zoning district. <br />C.
