He indicated that <br /> everything in the northeast corner of the county drains to Falls Lake. He pointed out the thick blue <br /> line in the middle of the map as the break line between the Jordan Lake Basin and the Falls Lake <br /> Basin. He said there is a small section in the northern part of the county that drains up to the <br /> Roanoke Basin in Virginia. He said the light blue areas on the map are the protected watersheds, <br /> and the darker blue areas are the critical watersheds. He explained that the darker blue <br /> watersheds are adjacent to the water supply reservoirs.After reviewing the acronyms on the slide, <br /> Christopher Sal explained the difference between density and impervious surface. He said the <br /> number of dwellings per unit of land is density, while impervious surface limits are the actual <br /> percentage of impervious area on a particular parcel as it relates to the overall size of the parcel. <br /> He said the lightest areas of the map do not specifically have lot density and impervious surface <br /> area requirements, but the county does manage stormwater and erosion control for those areas. <br /> He said there are also stormwater and erosion control requirements for every watershed in the <br /> county. <br />
