Studies have <br />shown that sediments, oils, and debris carried into the lake from highly urbanized areas have <br />a detrimental impact on the quality of water in the lake. The intent of Orono's ordinance is to <br />ensure that rainfall run-off will be cleansed by filtering through grassed or vegetated yard areas <br />before entering the lake. <br />Hardcover Zones - Allowed <br />Percentages: <br />0-75 <br />0 % <br />75-250' <br />25 % <br />250-500' <br />30 % <br />500-1000' <br />35 `7a <br />Hardcover includes: <br />- Roofs <br />- Sidewalks <br />- Paved or gravel driveways <br />- Patios & decks (includes slatted decks) <br />- Tops of retaining walls & rock wails <br />- Decorative landscape areas underlain by plastic sheeting or fabric <br />- Any other surface that does not allow direct absorption of rainfall into <br />the ground <br />LNSTRUCTION'S FOR COMPLETL;G HARDCO'�rER CA-LCULATION WORKSHEET <br />1.
