21 <br /> 1 out the thick blue line in the middle of the map as the break line between the Jordan Lake Basin <br /> 2 and the Falls Lake Basin. He said there is a small section in the northern part of the county that <br /> 3 drains up to the Roanoke Basin in Virginia. The grey areas of the map are the municipal <br /> 4 boundaries. The light blue areas on the map are the protected watersheds, and the darker blue <br /> 5 areas are the critical watersheds. He explained that the darker blue watersheds are adjacent to <br /> 6 the water supply reservoirs. Chris Sandt explained that there are maximum impervious surface <br /> 7 area restrictions as well as density restrictions that vary by watershed and are based on the <br /> 8 criticality of the watershed. He pointed out the West Fork on the Eno Reservoir (WFER), which is <br /> 9 owned and operated by the town of Hillsborough. The WFER is about three times the volumetric <br /> 10 size of Lake Orange. It was built between 1990 to 2010 with some recent upgrades in the last five <br /> 11 years. Lake Orange does not have an intake, nor does the WFER, unlike University Lake and <br /> 12 Cane Creek Reservoir. He explained that Lake Orange is the only reservoir that is subject to the <br /> 13 reservoir setbacks that can't be met because the lots are too small, as they were platted and built <br /> 14 before the rules existed. <br /> 15 <br /> 16 Slide #7 <br /> Impervious Surface Limits for WPQDs <br /> Table I—Impervious Surface Limits <br /> WaterashedProtettlon Impervious tamiu(Reside•ntial) Impervious Umits(Non-Residential) FAWN k-lop--Date <br /> (lvealy Dl3trltt <br /> Uri iveesity LakeCdtlolAm OXIII-W 6%twUDDlahle4,2_5A Wmptoao 6% Ap111,199D <br /> U-mray Um ProteM(IINIY- 6%(se OM Wk415.1 tm eaeptiml 12%(w1lX)41k 4.1.6 tar mgAkirM ApdIZ 1990 <br /> PW} <br /> Coo CreekCrltkalArm(CAK-CN 6%(snODD Table 41.5.1krescepm) 6% Dade 19,19" <br /> Cane Geek Pmteded(CAN 6PIU) 6%(we Mable 413A lw rueptm i 12%(*t UD041k41.6 Tar evtW"tl oaotm 19,1999 <br /> Upper Eno CrnkalAn(II-ENO-CA} 64(seeiMlaNle415.11W ftnoral 6% tawny 1,1994' <br /> 12%(oul irk of lrawtorr Areas) <br /> Upper Ga ProtedCed(D-EMD-Ml3D%(wdkinlmnimn Arras) 12%Isre UMW it CMior ercgAlmnl Jimay 1,1994' <br /> 76%(wdhin"hlgh dvrairy"er EDD Areas) <br /> 24%(wilhcwlaad Amer) 14%IWOi tur6 an69ullrrl <br /> lower Erro PmWed(L•ENO•PW) 36%Iwnhout curb and ptkd 36%Iwhhoot evrh aad gatie'l Jamamy 1,19% <br /> 70%(W10*1110 de 4rook") 704(wit high dmuty'or EDD Ama%l <br /> Wile Rive,holected(LITTLE-PWI 6%(see=TaW4,25.1INiso plops) 12%IseeUDOTaNt4.2.6for eueptirroo km"1.Twit <br /> 12%ladndee1 iramnkm Ar ) <br /> Ila (mkPmhd4d(O9K-PW) 3D%Iwnhialrarrsmon Area) 12%IsnODD W*41.6Jim eueptbrrsl <br /> 70%Iwrthin'hlo derrsdry"w EDD Areas) lamamy 1.1994 <br /> WIN I"EMkProtedad lNAU-PW) 12% 11%(see UM Wa04.2.6Tordnept1on0 hnmry 1,1994 <br /> Flat Rini Protected IRAT-MI 12% 12%Isee ODD Wile 4.2.6 farenepudnsl Jammy 1.1994 <br /> Haw ftlow Protedrd NIAW-PWI 24% 14% lawiry 1.19% <br /> kr"lake Prareded UORDAN-PW) 24% 24% laniary 1.1994 <br /> 'thrrr orcada9rroaaletteplAsrtsto rAe.EristAsg1kavAgmem mxrsyec;IeeoporcrA luored Aflrmrayfal rWn+roaLauPnrnnir(WFERI. <br /> ORANGE COUNTY <br /> NOIXM CAROLINA <br /> 17 <br /> 18 Chris Sandt said this table was created by staff in December 2024.
