1 Appendix: Development Patterns and Design Development Patterns Figure 1 lists the amount of land converted from undeveloped to some other form of land for the 13 county and 20 county Atlanta Region. In 2008, the 13-county Atlanta region converted 1,047,693 acres and the 20-county Atlanta region converted 2,088,709 acres. For the past 9 years, Coweta has led the 13 county region and Carroll County has led all counties in the 20 county region with the most acres converted annually. Figure 2 shows the projected development patterns for the 10-county Atlanta region as required by the Department of Community Affairs. The grey area of the region is considered to be developed, the orange area is projected to develop between now and 2040, the light green area is project to see little or no development, and the dark green areas on the map are those lands that are conservation areas, protected, or undevelopable. The amount and intensity of development in the grey or orange areas are not depicted and vary greatly depending on location.

3 Developments of Regional Impact (DRI) Figure 3 - DRI Non-Residential Development Trends Figure 3 above shows the location of all non-residential developments of regional impact (DRI) reviews have occurred over the past 10 years within the 10-county Atlanta region. These developments are large enough in size, or propose certain land uses, that are seen to have significant regional impact. Several areas of the region have seen many of these types of development proposed including the City Atlanta, Henry County and Gwinnett Counties along the interstates, and south Fulton County.

4 Figure 4 - DRI Residential Development Trends Figure 4 shows the location of all residential DRI reviews that have occurred over the past 10 years within the 10-county Atlanta region. While the location of these proposed developments are dispersed more than the non-residential developments as seen in the non-residential DRIs, they are still found in the same general areas of the region. The City of Atlanta in particular has attracted large developments of both types.

5 Figure 5 - Number of DRIs Reviewed and Average Residential Density Figure 5 lists the number and average gross residential density of DRIs in each jurisdiction in 10- county Atlanta region for the years The City of Atlanta had the highest average residential density for DRIs at 94.6 units per acre. This was followed by DeKalb and Cobb County with and units per acre respectively. The City of Atlanta saw the most DRIs reviewed with 56 followed by DeKalb with 33 and Gwinnett with 29. Rockdale and Douglas Counties had the lowest average density for DRIs while Rockdale and Clayton had the fewest DRIs reviewed.

6 Regional Urban Expansion and Infrastructure Comparison Figure 6 - Regional Urban Expansion and Infrastructure Comparison- Sunbelt Figure 6 compares the Urbanized Area (as defined by the US Census Bureau) and transportation infrastructure of Atlanta with those of its peers in the Sunbelt region of the U.S. Note that Atlanta has the largest area in square miles but does not have the largest population. Atlanta has one of the oldest transit systems of these six cities, but does not have the largest rail transit system. Also, the Atlanta region has built less transit infrastructure within the last 10 years than any of its Sunbelt peers in this figure.

7 Figure 7 - Regional Urban Expansion and Infrastructure Comparison Figure 7 compares the Urbanized Area (as defined by the US Census Bureau) and transportation infrastructure of Atlanta with those of its peers in terms of overall size in square miles. Note that Atlanta s population (within the Urbanized Area) is the smallest of the six while its size in square miles is third largest. Also, Atlanta has the least amount of high capacity transportation infrastructure (limited access freeways and fixed guideway transit) of all six cities. Each of the peers in this figure has expanded transit service to the extent of its urbanized area while the Atlanta region has not.

8 Land Conversion Figure 8 - Atlanta Region Land Conversion Figure 8 shows the land converted from undeveloped to any other development category between 2001 and This illustrates the areas in the region that are experiencing urban and suburban expansion. The two smaller maps on the left of the figure show existing land use in 2001 and The larger map on the right displays just those areas that were converted from undeveloped lands between 2001 and 2008, in red, totaling 144,074 acres. Areas at the central core of the region have also experienced significant growth during this time, but in many instances the development reused existing development sites and therefore would not be considered to have converted from undeveloped.

9 Existing Land Use Figure 9 - Atlanta Region Existing Land Use Figure 9 shows the existing land use for the 20-county Atlanta region. Note that the core 5 counties of Fulton, DeKalb, Cobb, Gwinnett, and Clayton are largely developed and consist mostly of residential uses while the remaining counties in the region consist of agriculture/forest uses with pockets of residential development.

10 Livable Centers Initiative One of the Atlanta Regional Commission s (ARC) principal goals is to support local governments in their efforts to create highly livable and vibrant communities. Few of our programs do that as effectively as the Livable Centers Initiative (LCI) program. The LCI program, adopted by ARC in 1999, is designed to help planners and governments more effectively link current and future land use planning to existing or planned transportation infrastructure. The program has spurred cities, counties and communities of all sizes to proactively plan for enhanced employment centers, town centers and transportation corridors, bringing a new level of livability to the region. Seen as a cutting-edge program around the country, the LCI program was awarded the American Planning Association s National Planning Excellence Award for Implementation in 2009, and was awarded the Environmental Protection Agency s 2008 National Award for Smart Growth. Figures 10 and 11 are graphs depicting those LCI areas with the most residential and office development within them since the program s inception in It is interesting to note that most of the office and residential development within LCIs has occurred in those LCIs within the region s core and major activity centers versus the many corridor and town center LCI study areas.

It appears there has been a fairly even distribution of development types within LCI areas thus far. Note the decrease in number of projects per year starting in This could be due to the beginnings of the economic slowdown or a reflection that many of the LCI areas are beginning to be built out.

12 Figure 13 compares residential, commercial, and office development within LCI areas with that of the 10 county region for the years While the LCI areas represent only 4.2% of the land area within the 10 county region, those same LCI areas contain 66.97% of all office space and 21.34% of all commercial space within the 10 county region. This is due in large part to the LCI program s focus on major activity centers and town centers. However, due to the 10 county region s abundance of housing, which makes up a majority of its land uses, only 8.51% of all housing in the 10 county region is found in LCI areas.
