Currently, the term DRI is unique to a few states and jurisdictions, including Florida, Georgia, Cape Cod, and Martha’s Vineyard. In Georgia, the Georgia Planning Act of 1989 gave the Department of Community Affairs (DCA) the power to create a methodology for the analysis of DRIs. In this methodology, new developments are judged by the Regional Commission to see if they meet the development thresh- olds set by the DCA. The size threshold is set by the type of the development as well as location of the development (whether or not it is a metropolitan region). The DRI review process is designed to increase the focus on quality growth, consider and plan for the impact on public infrastructure and services, and increase communication between localities, regions, and the state about new growth.[4] The Georgia Regional Transportation Authority (GRTA) was formed in 1999 to combat air pol- lution, traffic congestion, and poorly planned development in the nonattainment area around metro Atlanta.[5] As such, when a DRI meets the thresholds set by the DCA in its jurisdiction, GRTA must approve the development. GRTA requires a detailed traffic analysis as the main submittal for their analysis. 6 1.2 TRANSIMS TRANSIMS began at the Los Alamos National Laboratory as a new modeling tool for planning organizations. This computer model looks at both the individual interactions between vehicles and the overall effect on the network. After an initial development period, TRANSIMS switched from being a privately developed software into an open source software, which allows for individual users to customize TRANSIMS for their own use. The TRANSIMS software is built on a set of modules, which can be divided into a number of functions- network synthesis, population and ac- tivity generation, routing, and microsimulation. More details on individual modules are discussed in Chapter 3. 1.3 Summary As the name implies, a DRI is the construction or expansion of a facility that is planned to have a large effect on a region, not just a local area. TRANSIMS is a regional traffic microsimulator, so it follows that TRANSIMS could be a powerful tool to analyze DRIs. The rest of this report investigates the use of TRANSIMS to analyze DRIs. 7 Chapter 2 Developments of regional impact In this chapter, Developments of Regional Impact (DRI) are introduced and a brief survey of how they are evaluated in jurisdictions around the United States is presented. The Georgia Regional Transportation Authority (GRTA) DRI evaluation process is explored in greater detail. The intent of this chapter is to highlight key differences and similarities across the various jurisdictions, and to identify key steps to be accomplished within a technical analysis framework. 2.1 Developments of Regional Impact defined A Development of Regional Impact is a new development or expansion of an existing development that is large enough to have a significant impact the resources of a region. The variety of projects that can fall under DRI status include large-scale planned developments, airport expansions, office and industrial parks, mining operations, and sports and entertainment facilities. The criteria for defining what is or is not a Development of Regional Impact can include project type, size (acreage, number of units or square feet of development), or proximity to other development or critical areas of concern and may vary from one jurisdiction to another. In Georgia, the Department of Community Affairs (DCA) provides size thresholds to gauge the impact of the development prior to construction, by type of development. The thresholds are set in order to identify impacts of the development on other developments, transportation infrastructure, water and stormwater, wetlands, and governmental services.[1] 8 2.2 Georgia DRI Process While the Georgia DCA creates rules as to the analysis of DRIs, the responsibility for analyzing de- velopments falls to the local government or Regional Commission that the development is located within. For the Atlanta metropolitan area, the Atlanta Regional Commission (ARC) is the lead- ing agency for DRI’s, and analyzes the DRI for its impact on a variety of resources and services in the region.

A shapefile is a geospatial data format for use in geographic information system (GIS) software. Shapefiles spatially describe vector data such as points, lines, and polygons, representing, for instance, landmarks, roads, and lakes. The Environmental Systems Research Institute (Esri) created the format for use in their software, but the shapefile format works in additional Geographic Information System (GIS) software as well. 1.2 What are TIGER/Line Shapefiles?

  • Glossary of Redistricting Terms
    Glossary of Redistricting Terms Apportionment or Reapportionment Following each decennial census, seats in the United States House of Representatives are apportioned to each state based on population figures derived from the census. Apportionment is the process of determining how many Congressional Districts to allocate to each state, and is different from ‘redistricting,’ which involves redrawing district lines within a state. At-large An election in which candidates run in all parts of a jurisdiction rather than from districts or wards within the jurisdiction. All members of EVIT’s Board of Governors are elected from specific districts within EVIT’s boundary. There are no at-large election contests. Census Block The smallest level of census geography used by the Census Bureau to collect and report census data. Census Blocks are labeled with a four digit number such as 2025 or 1006A. Census Block Group A group of Census Blocks all having the same first block digit. Block 2025 is in Block Group 2. There are 1,023 whole or partial Block Groups within EVIT’s jurisdiction. The latest available population data for this redistricting process is at the Block Group level. Census data Information and statistics on the population of the United States gathered by the Census Bureau and released to the public. Census Tract A level of census geography larger than a census block or census block group that often corresponds to neighborhood boundaries. There are 385 whole or partial Census Tracts within EVIT’s boundary – too few for our purpose in redistricting. Community of interest An area that is defined by residents’ shared demographics or by common threads of social, economic, or political interests such that the area may benefit from common representation.

  • Census Bureau Public Geocoder
    1. What is Geocoding? Geocoding is an attempt to provide the geographic location (latitude, longitude) of an address by matching the address to an address range. The address ranges used in the geocoder are the same address ranges that can be found in the TIGER/Line Shapefiles which are derived from the Master Address File (MAF). The address ranges are potential address ranges, not actual address ranges. Potential ranges include the full range of possible structure numbers even though the actual structures might not exist. The majority of the address ranges we have are for residential areas. There are limited address ranges available in commercial areas. Our address ranges are regularly updated with the most current information we have available to us. The hypothetical graphic below may help customers understand the concept of geocoding and Census Geography (addresses displayed in this document are factitious and shown for example only.) If we look at Block 1001 in the example below the address range in red 101-199 is the range of numbers that overlap the actual individual house numbers associated with the blue circles (e.g. 103, 117, 135 and 151 Main St) on that side of the street (i.e. the Left side, note the arrow is pointing to the right on Main Street.) Based on this logic, the from address would be 101 and the to address would be 199 for this address range. Besides providing a user with the geographic location of an address the Census Geocoder can also provide all of the additional Census geographic information associated with a location, for example a Census Block, Tract, County, and State.

  • 2030 Wisconsin State Airport System Plan
    8.0 Environmental Justice 8.1 Chapter Purpose and Content Wisconsin is committed to integrating the principle of environmental justice into all transportation planning programs and activities. For purposes of this chapter, environmental justice populations are defined as including minority, low-income, children (age 17 and under), seniors (age 65 and older) and zero-vehicle household populations. These environmental justice populations have been assessed in relation to their geographic location, and the presence and operations of the statewide airport system. The information contained in this chapter includes an evaluation of the relationship between the Wisconsin State Airport System Plan (SASP) recommendations and environmental justice populations. This environmental justice chapter also supplements the system plan environmental evaluation included in Chapter 9, which discusses the potential environmental and community impacts of implementing the SASP. Lastly, this chapter identifies areas for consideration during future planning and project-level activities. It is important to note that this evaluation discusses the SASP recommendations at a state-wide system level. Prior to implementation of each individual project, individual project specific environmental reviews will be completed which will include an environmental justice evaluation. The implementation of any specific improvement identified in this plan remains the responsibility of local airport sponsors, and the projects identified do not constitute a commitment of either state or federal funding. The approval and project justification of local master planning efforts, environmental review processes and funding approvals remain a sponsor responsibility. Similar to Wisconsin’s Long-Range Transportation Plan (Connections 2030), the SASP is a policy- based plan developed to be flexible and responsive to shifts in investment priorities.

  • Historical Glossary (2010S)
    Historical Glossary (2010s) A American Community Survey (ACS) An ongoing census survey sent to a sample of three million housing units annually. The ACS collects detailed demographic and socioeconomic population and housing characteristics, similar to the information collected on the former long-form census questionnaire. The data is collected continuously rather than once a decade, so the ACS provides more current data. Single‐year estimates are available annually for geographic areas with a population of 65,000 or more. Three‐year estimates are available annually for geographic areas with a population of 20,000 or more. In December 2010, the first five‐year estimates at the census tract and block group level were made available. Anglo Those persons who identified their race on the census form as White only and not Hispanic. Assignment unit Any unit of geography that may be used as a building block to draw a redistricting plan. Assignment units available in RedAppl are counties, census tracts, census block groups, census blocks, and VTDs (voting tabulation districts). B Black Those persons who identified their race on the census form as Black, African American, or Negro only or Black and any other race. Black persons can be either Hispanic or non-Hispanic. Black + Hispanic A combined population category that includes all persons who identified their race as Black and all persons who identified themselves as Hispanic. The total is adjusted so that those who indicated they were both Black and Hispanic are not counted twice. The category is frequently examined for redistricting purposes in areas in which Black and Hispanic voters may form political coalitions or vote together as a bloc.

The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line File is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. Block Groups (BGs) are defined before tabulation block delineation and numbering, but are clusters of blocks within the same census tract that have the same first digit of their 4-digit census block number from the same decennial census. For example, Census 2000 tabulation blocks 3001, 3002, 3003,.., 3999 within Census 2000 tract 1210.02 are also within BG 3 within that census tract. Census 2000 BGs generally contained between 600 and 3,000 people, with an optimum size of 1,500 people. Most BGs were delineated by local participants in the Census Bureau's Participant Statistical Areas Program (PSAP).

  • Geographic Levels in NEO CANDO 2010+
    Geographic Levels in NEO CANDO 2010+ Data in NEO CANDO 2010+ are available at several levels of aggregation including census geographies and locally defined geographies. Descriptions of each of the different aggregations are provided below. For more detailed information about the census geographies click here. All of the data in NEO CANDO 2010+ are based on 2010 tract boundary definitions. In addition to the 2010 Census and estimates from the American Community Survey (ACS), NEO CANDO 2010+ provides estimates of the 2000 census data in 2010 census geography. Because of changes in boundaries between 2000 and 2010, we have estimated the 2000 data using apportionment methods. We also geocode data we receive at the address level and assign and aggregate it to the 2010 census geography. Census tract level data are available for the following 17 counties: Ashland, Ashtabula, Columbiana, Cuyahoga, Erie, Geauga, Huron, Lake, Lorain, Mahoning, Medina, Portage, Richland, Stark, Summit, Trumbull, and Wayne. Keep in mind that some census tracts have changed numbers, been split, or changed physical boundaries over the last decade. Analysis of trends over time requires that data be based on the same geographic boundaries. A tract that existed in 2000 may not exist in 2010; the tract number may have changed, or the physical boundaries may have changed. We ensure the user is comparing apples to apples by converting all of our data in NEO CANDO 2010+ into the same geographic boundaries -- 2010 geography. The user should not compare data in the 2000 geography to data in the 2010 geography. CENSUS GEOGRAPHIES1 Census Block Census blocks are the smallest census geography.

    3. Geographic Shapefile Concepts Overview The following sections describe the geographic entity type displayed in each shapefile, as well as the record layout for each file, in alphabetical order. A listing of all available shapefiles, including vintage and geographic level (state, county, and national), precedes the description of the entity type. 3.1 American Indian / Alaska Native / Native Hawaiian (AIANNH) Areas 3.1.1 Alaska Native Regional Corporations (ANRCs) Alaska Native Regional Corporations geography and attributes are available for Alaska in the following shapefile: Alaska Native Regional Corporation (ANRC) State Shapefile (Current) ANRCs are corporations created according to the Alaska Native Claims Settlement Act (Pub. L. 92–203, 85 Stat. 688 (1971); 43 U.S.C. 1602 et seq. (2000)). The laws of the State of Alaska organize “Regional Corporations” to conduct both the for-profit and non-profit affairs of Alaska Natives within defined regions of the state. The Census Bureau treats ANRCs as legal geographic entities. Twelve ANRCs cover the entire State of Alaska except for the area within the Annette Island Reserve (an American Indian Reservation under the governmental authority of the Metlakatla Indian Community). There is a thirteenth ANRC that represents the eligible Alaska Natives living outside of Alaska that are not members of any of the twelve ANRCs within the State of Alaska. Because it has no defined geographic extent, this thirteenth ANRC does not appear in the TIGER/Line Shapefiles and the Census Bureau does not provide data for it. The Census Bureau offers representatives of the twelve ANRCs the opportunity to review and update the ANRC boundaries.
