2 September 2006, GTG completed its work and delivered the address and street centerline layers to Orange County Land Records staff. GTG determined there were 65,745 addressable structures of which 294 needed addresses. More than 10,000 were unverified and 2,625 needed readdressing due to location, numerical sequence, or physical access. These discrepancies represented a potential public safety exposure for the persons occupying those structures. Staff has since worked with postal carriers, tax appraisers, and ES staff to reduce the unverified number to 1,745. At the conclusion of GTG's work, its primary recommendation was that Orange County adopt an addressing ordinance that would bring the 2,625 locations that need readdressing into conformance with the new address model and prevent addressing errors from occurring in the future. This action would result in a more reliable delivery of emergency services. In May of 2008, ES contracted with its 911 CAD vendor, Logisys, to upgrade the existing CAD software so that it could incorporate the new address point data and improve the delivery of services. GIS staff worked closely with staff from several County departments, Chapel Hill, Carrboro, and the Logisys contractors throughout 2007 and 2008 to redesign the County's address and street centerline data model to 1) make it compatible with the Logisys CAD system, 2) meet the needs of all County and municipal staff who require the use of addresses and streets, and 3 meet the impending State and Federal requirements necessary for grant applications and soon-to-be mandated integration. GIS staff coordinated with all interested parties to leverage the technology of the recently implemented enterprise GIS system to integrate the address jurisdictions of Chapel Hill and Carrboro into the County's GIS. Prior to this development, Chapel Hill and Carrboro would assign addresses, then weeks or months later, notify the County of new addresses through a manual process of passing paper maps or CD's of digital data. This caused significant time delays in the accuracy of the GIS database while not providing a comprehensive system across all County addresses. Since this milestone of GIS synchronization, Chapel Hill and Carrboro have replicas of the address and street database. When the towns assign new addresses or make updates to streets, those changes can be immediately synchronized with the County's primary production database, which is then synchronized with the data warehouse and Logisys CAD system nightly. Address updates from Chapel Hill and Carrboro have gone from being a monthly process to a near real-time process. This allows emergency responders to respond quickly to calls at newly addressed building sites, which can often be dangerous places with a strong need for emergency services. It also aids in routing other County services to new customers (solid waste/recycling pickup, building inspectors, tax appraisers, etc.), as well as improving efficiencies in assessment and collection of personal and real property taxes. This example of GIS integration is a major achievement for Orange County and its municipal partners. Orange County's work is the first and only example of this type of cross-jurisdictional cooperative effort utilizing the synchronization technology within the state of North Carolina. In February of 2009, Orange County's GIS Director was invited by NCCGIA (North Carolina Center for Geographic Information & Analysis) to give a presentation at the bi-annual NC GIS Conference in Raleigh in order to promote these types of inter-governmental relationships and data integration. This presentation was received very positively with other counties contacting County staff for detailed information on the processes and methodologies. The CAD vendor, Logisys, promotes the address data and integration architecture as a model to its other customers. Based on the positive feedback from both Chapel Hill and Carrboro, Hillsborough is working with the County to achieve a similar level of integration. The generous amount of
