This <br />results in more stormwater flowing directly into streams and other water bodies. Because this <br />direct runoff has not been filtered through the soil, pollutahl.4 from the air and land surface enter <br />streams and increase the potential for pollution of drinking water supplies.' <br />725 From SW Ord Section 3 <br />728 ZO 6.23.7(c) <br />727 Not permitted by State, therefore deleted <br />728 Merging stormwater regs from ZO (Countywide) & Stonnwater Ordinance (Neuse only); see UDO Notes <br />729 ZO 6.23.3 first paragraph <br />Orange County, North Carolina - DRAFT Unified Development Ordinance Page 6 -144 <br />
