rely when making decisions related to issues such as planning, land use, annexation, zoning, and growth management. One of the recommendations contained in the Efland-Mebane Small Area Plan is to amend Orange County's "Primary Service Area" on the map that is part of the Agreement (see pages 69-71 and 82 of plan). Attachment 3 is a map that shows the proposed changes to Orange County's Primary Service Area (PSA) in Cheeks Township. The area to be added to the PSA in the southeast portion of the existing PSA (in the vicinity of Mt. Willing Road and Interstate 40/85) reflects the proposed new "Critical Area" boundary for Seven Mile Creek (further discussed in the next section). It should also be noted that the two areas currently in the PSA proposed for removal from the PSA are not part of the Efland-Mebane Small Area Plan recommendations; rather, staff is proposing them for deletion to be consistent with the Land Use Element Map and the County's development goals and policies. The areas proposed for removal from the PSA would be changed to "Orange County Long-Term Interest Area." The Town of Hillsborough is also interested in amending its Primary Service Area to be in keeping with the outcomes of the Hillsborough-Orange County Strategic Growth Plan. Town officials are currently discussing whether the Town will bring its amendments forward at this time. Amendments to the WASMPBA require the approval of all agreement signatories. Planning staff proposes to meet with the staff of signatory entities to discuss the proposed changes and devise a process to bring agreement amendments forward to the various governing boards. Staff is requesting BOCC authorization to begin this amendment process. Upper Eno Watershed Critical Area One of the recommendations of the Efland-Mebane Small Area Plan is to re-evaluate the Critical Area boundary for Seven Mile Creek because the boundary is based upon a reservoir being created on Seven Mile Creek and the full pool elevation of the reservoir was used as the calculation point for the '/2-mile Critical Area boundary. A reservoir is no longer being proposed so the Critical Area boundary should be changed to reflect this. Attachment 4 is a map depicting the proposed revisions to the Seven Mile Creek Critical Area boundary. Since Seven Mile Creek is still a water supply source for the Town of Hillsborough's water supply, a '/2-mile buffer from the centerline of the "fifth order" segment of the creek will continue to apply. As an aside, stream orders are a stream hierarchy determined by the number of tributary confluences flowing into a particular stream. Staff is also suggesting that previous changes to the Upper Eno Critical Area be formalized. In 2005, staff re-drew the original 1994 critical area boundary to be consistent with the text of the Zoning Ordinance. The revised boundary was placed on the Land Use Element Map and the Zoning Atlas. Recent developments in other jurisdictions in the State have led staff to conclude that even though the boundary was drawn to reflect the pertinent text in the Zoning Ordinance, the map changes should go through the formal procedure to amend the Land Use Element Map and the Zoning Atlas. Attachment 5 depicts both the original 1994 Critical Area line and the revised 2005 Critical Area along with the various '/2-mile buffers of the stream segments and impoundments. Staff is planning to place the Upper Eno Critical Area revisions on the February 2010 Quarterly Public Hearing agenda. The revisions will be to both the Land Use Element Map and the
