| Description: | The North Carolina Department of Transportation (NCDOT) uses of Geographic Information Systems (GIS) technology to predict and quantify potential archeological impacts in order to streamline the identification of archeological resources early in the NEPA process. Under North Carolina's merged NEPA/Section 404 permit process, preliminary design and environmental data are gathered and analyzed for all NCDOT projects. These data are then used to select the best alternative for construction for projects needing an Environmental Assessment (EA) or Environmental Impact Statement (EIS). Considering environmental issues at the front end of the NEPA process fosters better decision-making, especially when selecting the build alternative. Of all of the environmental constraints, only archeological resources are not identified and evaluated to the same degree as community impacts, wetland delineation, and air/noise issues. Cost, right of entry agreements, project schedule, and lack of background information on known sites within a proposed project's area of potential effects often delay the identification and evaluation of archeological sites. In response, Section 106 regulations allow for a phased identification process using background reports and/or archeological probabilities to establish context based on information from known sites near a given project. Aside from the NEPA-driven rational for applying GIS technology, NCDOT is using its model of archeological sensitivity for all alternatives contained within project corridors to better understand the scope, cost, and timeframe associated with their field efforts. This allows NCDOT to generate more realistic project schedules. NCDOT's approach allows summary tables quantifying a project's probable archeological impacts to be available early in the planning process. In addition, NCDOT can easily adapt to changes that occur throughout the life of a project, including the addition of new corridors and or alternatives for study. By using GIS, a clear understanding of the new alternative's archeological potential can be generated quickly without the need to revise or create addenda to an existing report. NCDOT's new approach also fosters the coordination of state and Federal agencies responsible for compliance with NEPA and Section 106. In order to make the GIS approach work, the massive amount of archeological site data contained at the Office of State archeology (OSA) must be available for review and analysis in digital format. These data are currently maintained primarily on paper and microfiche. NCDOT is creating and maintaining a digital database for the model development process. As a result, OSA will have digitized archeological site information to use for future planning purposes. Ultimately, OSA and NCDOT will access the archeological data through a web-based environment, significantly streamlining the process. OSA will also be able to incorporate new site information in a more timely and efficient manner. Once the initial information is created in a digitized format and refined through field efforts, certified local governments, cities, county agencies, and regional planning organizations will be able to better plan their undertakings at a reduced cost. | |

| Description: | FHWA's Winter 2012 GIS in Transportation Newsletter describes the development of a quantitative Road Vehicle Inventory (RVI) GIS layer by the North Carolina State University's Institute for Transportation Research and Education (ITRE). The RVI integrates truck exposure (truck counts) with roadway inventory data (pavement condition, bridge condition, etc.). By weighting these factors, vulnerability values can be assigned to road segments statewide.

| Description: | Go!NC is an ArcGIS Online-based data portal that consolidates, aggregates, and shares geospatial information for both internal and external users. The site provides an intuitive interface through which users—even those without advanced GIS expertise— can manipulate geospatial information and develop maps on demand. NCDOT’s GIS unit sets quality and metadata standards for Go!NC, but empowers business units to develop and manage their own maps and data on the site. Go!NC is used by a wide range of NCDOT’s partner agencies, including the State Wildlife Resources Commission and Department of Health and Human Services, helping to establish a foundation for improved inter-agency coordination. | |

| Description: |
In 2003, the North Carolina Geographic Information Coordinating Council (GICC) adopted four priority areas to serve as a guide for Council activities. These four areas
are: (1) develop a common understanding of North Carolina data resources; (2) prepare an
ongoing data inventory for all geospatial data holdings across North Carolina; (3) develop data
content standards for key data themes along with cost projections for maintaining those themes;
and (4) enable more widespread use of geospatial data through better access and distribution of
the data. The adoption of NC OneMap as a new vision for North Carolina was a key step in
executing the GICC work plan.
NC OneMap allows users to view geographic data seamlessly across North Carolina, search for and download data for use on their own GIS, view and query metadata, and determine who has what data through an on-line data inventory. |

| 8 | Practice: | NCDOT's GIS Use for Southeast High Speed Rail Constraint Mapping |
| Subject Area: | Planning | |

| Title: | Rail Environmental Programs Manager | |

| Description: | The North Carolina Department of Transportation (NCDOT), the Federal Highway Administration North Carolina Division and the Federal Railroad Administration are leading the development of the tiered Environmental Impact Statement (EIS) for the Southeast High Speed Rail Program. The rail line would connect Washington D.C. with Charlotte, North Carolina and eventually would provide continuous high-speed rail service between Boston, Massachusetts and major markets farther southeast. The Tier 1 EIS has been completed, and a Record of Decision was signed in October 2002. Preparation of the Tier 2 EIS began in late 2002. NCDOT, along with the Virginia Department of Rail and Public Transporation, is using GIS to conduct initial constraint mapping for the Tier II Environmental Study. NCDOT is using GIS to examine different alignments for the rail corridor segment between Petersburg, Virginia and Raleigh, North Carolina. Since the rail corridor interacts with the Interstate highway system at several locations along the proposed corridor (I-85 and US Route 1 run parallel to the proposed rail corridor), GIS has helped planners identify grade crossings, while avoiding alignment choices that could adversely affect mobility on the Interstate system, as well as the surrounding environment. | |

| Description: | The Tulula Creek Wetlands Mitigation Site is a project undertaken by the North Carolina Department of Transportation (NCDOT) in the Blue Ridge Mountains of North Carolina. Construction of a golf course began at the site, but was eventually abandoned. NCDOT's project involved restoring the Tulula Creek wetland area to its original state. The Department partnered with nearby universities and state environmental agencies to collect and assess a whole range of baseline data, which were analyzed using a Geographic Information System database. Their research provides important information to the limited body of knowledge on the ecology of southern Appalachian floodplain forests, which will be useful in future restoration projects. | |
