13 <br /> Attachment- Letter and Map from OWASA <br /> Orange Water and Sewer Authority <br /> 10WASA OWASA is Carrboro-Chapel Hill's not-for-profit public service agency <br /> delivering high quality water,wastewater,and reclaimed water,services. <br /> August 20.2019 <br /> Perdita Holtz,AICP <br /> Planner ill-Planning Systems Coordinator <br /> Orange County,NC Planning Department <br /> 200 South Cameron Street <br /> PO BOX 8181 <br /> Hillsborough NC 27278 <br /> Dear Ms.Holtz: <br /> I am writing in response to your July 3,2019 email request regarding the potential provision of <br /> water and sewer in southern Orange County. Thank you for meeting with me to clarify your <br /> request and for supplying the GIS layer for your area of interest to overlay on our service area <br /> maps. You defined the area of interest in G I S as the triangle along the southeastern part of the <br /> county,i not uding 1,901 acres of southern rural buffer and 208 acres of Chapel Hill transition <br /> zone{shown in green and cross hatch,respectively,on the attached map}. I have also looked <br /> at the unserved area north of the triangle and south of the OWASA service boundary. The <br /> County is of course aware that OWASA wilI not accept new water or sewer customersautsida of <br /> the Water and Sewer Management Planning Boundary Agreement(WSMPBA),and that <br /> changes to the boundary would be necessary to serve such areas. <br /> Answering your questions in detail would require contractor and modeling assistance, however, <br /> I've taken a high-level look to provide you some information for early planning. Watershed <br /> areas were delineated by GIS using LIDAR data, and the general direction of surface flows was <br /> used to determine whether a watershed flowed toward or away from OWASA's infrastructure. <br /> No review of parcels was performed to determine if an individual parcel was serviceable. In <br /> addition, easements which do not follow roadways may be required along very specific routes to <br /> open areas for service. <br /> Sewer <br /> The attached map delineates the areas where topography directs surface flow both toward and <br /> away from the OWASA service area, shown on the map by the Gravity Sewer Boundary. This <br /> boundary should correlate with the areas which should be serviceable by gravity sewers and <br /> areas which cannot. You will note the similarity between the Gravity Sewer Boundary and the <br /> WSMPBA boundary east of Old Lystra Road. <br /> In general,the region located to the south and east of the Gravity Sewer Boundary cannot be <br /> served without pumping to the OWASA system. Planning to serve this area would require <br /> consideration of several factors,including the need and costs for: <br /> ■ new gravity sewer lines for the new development to carry the wastewater to pump <br /> stations, <br /> • multiple pump stations, <br /> • force mains to carry pumped wastewater northward toward the service area, <br /> 400]anes ferry Road,Carrboro NC 77S W 0 919-968-4411 Q info@"asa.org © GOWASAI v rrvrx.awasa.org <br /> - 12- <br />
