• <br /> existing reference to "University Lake" watershed, thus removing <br /> University Lake from the requirements of the WQCA district. ] <br /> C.

Amend Article 4 by adding a new Article 4 .2 . 30 University Lake <br /> Watershed (ULW) District to read as follows : <br /> a.

Since a major <br /> source of toxicants and nutrients are impervious surfaces <br /> such as roads, roof tops, and driveways, land use management <br /> practices control the amount and location of such surfaces . <br /> OPTION 1_1 <br /> The intent of the University Lake Watershed (ULW) District is <br /> to apply a set of regulations involving the use of structural <br /> devices which protect the watershed by preventing substantial <br /> portions of the. pollution generated by future development <br /> from reaching University Lake. Since a major source of <br /> toxicants and nutrients are impervious surfaces such as <br /> roads, roof tops, and driveways, structural devices such as <br /> stormwater detention ponds trap pollution near the point of <br /> origin. <br /> b. Application Criteria <br /> The University Lake Watershed (ULW) District is established <br /> as a district which overlays other zoning districts <br /> established in this ordinance. The new use of any land or any <br /> new structure within the ULW district shall comply with those <br />
