Studies have shown that sediments, cils, and debris carried into the lake <br />from h:ihly 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 vegeta`ed yard areas before entering the <br />lake. <br />B. HARDCOVER SETBACK ZONES - PERCENTAGE ALLOWED <br />I. 0-751: in the area within -5' of the lakeshore, No Hardcover is allowed <br />(01). -- -- <br />II. 75-2501: 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. 250-500's in the portion of the lot located between 250' and 500'feet <br />frcm the lake 301 of that portion of the lot ma be hardcovered. <br />IV. 500-1,000': in the portion of the lot located between 500' and .1,000' feet <br />from the lake 351 of that portion of the lot may be hardcovered. <br />NOTE: Those: regulations apply even if you have a lot thst does not at. :t the lake but is <br />within a lakeshore zoning district.. <br />C.
