21 <br /> out the thick blue line in the middle of the map as the break line between the Jordan Lake Basin <br /> and the Falls Lake Basin. He said there is a small section in the northern part of the county that <br /> drains up to the Roanoke Basin in Virginia. The grey areas of the map are the municipal <br /> boundaries. The light blue areas on the map are the protected watersheds, and the darker blue <br /> areas are the critical watersheds. He explained that the darker blue watersheds are adjacent to <br /> the water supply reservoirs. Chris Sandt explained that there are maximum impervious surface <br /> area restrictions as well as density restrictions that vary by watershed and are based on the <br /> criticality of the watershed. He pointed out the West Fork on the Eno Reservoir (WFER), which is <br /> owned and operated by the town of Hillsborough. The WFER is about three times the volumetric <br /> size of Lake Orange. It was built between 1990 to 2010 with some recent upgrades in the last five <br /> years. Lake Orange does not have an intake, nor does the WFER, unlike University Lake and <br /> Cane Creek Reservoir. He explained that Lake Orange is the only reservoir that is subject to the <br /> reservoir setbacks that can't be met because the lots are too small, as they were platted and built <br /> before the rules existed. <br /> Slide #7 <br /> Impervious Surface Limits for WPODs <br /> Table I—Impervious Surface Limits <br /> WatersOve dahedProtetti6Ek <br /> Overlay District Imp"ous limits(Residential) Impervious Um its(Hon-Residential) EAstingDeveltipmentDate <br /> University LakeCritical Ana(UNI1l-CA) 6%UftL 01abk 4.2.5.11or rm[rpnons) 6% Ap112.1M <br /> Un iversity lake Prri,"d(UNW- 6%(see0001abk4.25.11crewpnom) 12%(we 00 Eahie 4.2.6 fm eueptiono Apol2.199D <br /> PW) <br /> Cue(mek(rokal Area(CANE-M 64s(see00011bk4.2.5.1fwmvpuoml 6% wow 19.1999 <br /> (me(reek Protected(CAN FPW) 6%(we UM Table 4111 Ter MTPtimi 12%Ism UDD Talk 4.2.61or eueptioml Dttobrr 19,10M <br /> Upp"Issv01kalArea(U-111 H/U 6%ItaeuDDffik4.7.5.l lot eecep6wnl 6% lanwry1,1991' <br /> I Z%(outLde of rwmawl ANNO <br /> Upper Erm I'mtected(11•EN0•PWi X%lwnhin 7caminon Areas) 12%(seeUDD lahke4.2A Tor-epbons) January 1,MC <br /> 7A(wdhm-bigh denary'a EDD krns) <br /> 24%(with cwh and gutterl 24%Nvl1h curb and getlrr( <br /> Lower l n o Pmwted(1 M.PWI 366e(withml curb and goerJ 36%IvAhan[curb and goner} Yanvary 1,1994 <br /> 70%Wtht llo dendcy'w EDD Areas) 70%(wh1Ma'hrgh deputy or[DO Areas) <br /> LiMeAiver Rotected{UME-PfY) 6%(wUDD bble4.7.5.3 for c�gtioml 12%(see UDO We 4.2.6 kr exeptlam) )smiary 1,1994 <br /> 12%(XtsldeM Tomdrvn Areash <br /> 8ark(reek Pivwc.d(8A(N-PW) 30%(wdhin lranprWn Areas) 12%Isee UDO TM 42.6 Tor ezcCpt*W <br /> 70%(within"Nigh dem ly'cue EDOAreu) }anvary 1,1994 <br /> SpMh"freek PmtaeeN Iffla-ml 12% 12%(see UDOTWe 426 Toreueplk ) fanuary t.19% <br /> Flat Rive Pm[eeted(FLA1•PWI IZ% 12%Isee UDO Table 4.26 Tor euWlomn January 1,19% <br /> Flaw R6wPmte1ed MAWPWI 14% 24% January 1,19% <br /> krdm Lake Pmtectrd IIORDAN*M 7dae N% kiviwy 1,1994 <br /> •D+errweodddivnurmpra.rs mcAe Cnstk+g pnrlapmen10urrspenhr topanrlr lased adprm lu Ow WW krsrfnoAn EWACP2. <br /> �1 <br /> ORANGE COUNTY <br /> NORTH CAROLINA <br /> Chris Sandt said this table was created by staff in December 2024.
