Data Use: This layer represents the City of Dallas’ future land use based on parcels data derived from Dallas County, Collin County, Kaufman County, Rockwall County and Denton County. The placetypes in this plan represent the form of future development as envisioned by the Dallas community. These placetypes will in turn provide the macro-level guidance that will help to inform the City’s future Development Code Update and possible Citywide Urban Design Guidelines. Placetypes describe the long-term vision and desired building and preservation characteristics for different places within the city including neighborhoods, mixed-use areas, employment and industry centers, and open spaces.They provide a high-level guide for the desired mix of land uses, design and the recommended intensity and scale of the different uses. The placetype descriptions are translated into a graphical placetype map that provides the long-range visual view of the different places in Dallas.The unique characteristics included in each of the placetypes are rooted in over two years of community input and thousands of comments from people across the city of Dallas. Data Source: This feature layer is based on certified appraisal data obtained from each individual county's appraisal district (Dallas, Collin, Rockwall, Kaufman, and Denton Counties) for certified tax accounts in the city.Year: 09-25-2024

Description: These layers contains the nonattainment and maintenance areas (counties) in Texas. It was derived from the EPA’s Greenbook. A nonattainment designation means an area has not achieved compliance with the National Ambient Air Quality Standards (NAAQS). A maintenance designation means the area was formerly in nonattainment but has monitored attainment and is currently under a maintenance plan1. The U.S. Environmental Protection Agency (EPA) established the 8-Hour ozone NAAQS in 1997 and revised it with the 2008 and 2015 standards. The 1997 ozone NAAQS was revoked in April 6, 20152, along with the classifications, so the current maintenance designation is based on the approval of a maintenance plan by EPA for the region; rather than an official reclassification. These nonattainment counties were designated by the EPA based on their air quality monitoring data. Before it was revoked, there were 17 nonattainment counties for the 1997 ozone NAAQS: 8 counties in the Houston/ Galveston area (Brazoria, Chambers, Fort Bend, Galveston, Harris, Liberty, Montgomery, and Waller); and 9 counties is the Dallas/Fort Worth area (Collin, Dallas, Denton, Ellis, Johnson, Kaufman, Parker, Rockwall, and Tarrant). There are 3 maintenance counties for the 1997 ozone NAAQS in the Beaumont/Port Arthur area (Hardin, Orange, Jefferson)3. There are 18 nonattainment counties for the 2008 ozone NAAQS: 8 counties in the Houston/ Galveston area (Brazoria, Chambers, Fort Bend, Galveston, Harris, Liberty, Montgomery, and Waller); and 10 counties in the Dallas/Fort Worth area (Collin, Dallas, Denton, Ellis, Johnson, Kaufman, Parker, Rockwall, Tarrant, and Wise)4. There are 16 nonattainment counties for the 2015 ozone NAAQS: 1 county in the San Antonio area (Bexar); 6 counties in the Houston/ Galveston area (Brazoria, Chamber, Fort Bend, Galveston, Harris, and Montgomery); and 9 in the Dallas/Fort Worth area (Collin, Dallas, Denton, Ellis, Johnson, Kaufman, Parker, Tarrant, and Wise)5. The EPA established the NAAQS for particulate matter with a diameter of 10 micrometers or smaller (PM-10) in 1987. There is one nonattainment area for the 1987 PM-10 NAAQS: which is a portion of El Paso county6. The EPA established the NAAQS for carbon monoxide (CO) in 1971. There is one maintenance area for the 1971 CO NAAQS: which is a portion of El Paso county7. References:1.
