As Austin’s population continues to burgeon, growth pressures are already impacting areas that are slated to become regional, town, and neighborhood centers. Much of this growth is occurring on the east side as a result of issues such as gentrification, land costs, the construction of SH 130, etc. Considering that the private sector builds approximately 80 percent of our infrastructure and that City departments do not have the capacity to pre-define road locations on private land or how future development will look, the city is in need of a new “Structure Plan” that would predetermine where development and the construction of roads will take place over the next century. An area wide transportation, development, and open space infrastructure strategy will allow the city and county to guide development to achieve a more compact, connected, safer and affordable Austin.

America 2050 identifies the Texas Triangle as one of 10 emerging Mega-Regions in North America. This geographic area is defined by 4 of America’s fastest growing cities, with Austin-Round Rock occupying the western apex of the triangle. The Texas Triangle’s population would sit at nearly 24 million by 2030, under that scenario, the Triangle would swell by about 6 million people from 2015 to 2030, or more than 30 percent. With the population of the Austin-Round Rock region projected to reach 2,854,501 in 2030. The resulting demand on resources is already generating significant developmental pressure and increased demands upon the urban and environmental infrastructure of the region. As the Austin-Round Rock Metropolitan Region looks to the future, each of its cities are attempting to address common concerns on a regional scale and to share in complementary economic and environmental strengths. The City of Austin is undertaking a series of initiatives intended to transform Austin into a world-class city capable of sustaining this massive change.

_Crescent vs Archipelago
< Tra vis C
ount y>
The ‘Eastern Crescent’ is a new term in the Austin lexicon introduced by Council member Ora Houston. The ‘Eastern Crescent’ describes a large portion of East Austin with notable social, economic, and demographic challenges. These challenges, such as food deserts, declining population of black residents, income inequality, and lower voter participation, appear clearly as a crescent shape when individual variables are mapped across the city.
Elgin
Because the City of Austin is working to establish multiple population and employment centers a ‘crescent’, with its uniform layers and single common center, is an unhelpful metaphor. Like a crescent roll’s layered dough, the term ‘Eastern Crescent’ connotes concentric layers moving away from the downtown center. ‘Eastern Archipelago’ is a preferable conceptual framework for East Austin. Rather than a uniform development pattern radiating away from downtown, East Austin is envisioned to have targeted centers of development. East Austin will be characterized by significant area of conservation and agriculture punctuated with islands of population and job centers.

_AREA NEEEDED FOR GROWTH
According to Envision Tomorrow, the city of Austin only has approx. 17,000 acres left to develop within its 174,000 acres. Most, if not all, of the available land in Austin is found within its eastern crescent. As such, the area is expected to grow by over 350,000+ people during the next 20 years. Because there is not sufficient land area to accommodate this growing population within city limits, Austin will be pushed to develop eastward. At 4 units per acre (current development pattern) : 25 miles
35,000 acres are needed to accommodate 350,000+ new residents. At 10 units per acre (a sustainable, affordable and compact development pattern) : 14,000 acres are needed to accommodate the same amount of people.

The Archipelagram is a development strategy for East Austin that locates new districts with appropriate density in strategic locations along thoroughfares. However, the focus of density is not along corridors, but rather at their crossings. This approach leaves rich agricultural land and space for parks and green infrastructure to direct development opportunities in a polycentric scheme. The Archipelagram diagrams East Austinâ&#x20AC;&#x2122;s key radial thoroughfares; 183, 130 & 45, with its routes to the city center; Highway 290, 969 (MLK) and 71. Additionally, the diagram considers two key geographical features of the east side; the Colorado River and Walter E. Long Park, along with emerging centers and key landmarks; COTA, the town of Manor, the airport and nearby Elgin and Bastrop. â&#x20AC;&#x153;The skeletonâ&#x20AC;? for the Archipelgram is provided as a tool to understand proposals for the landscape, mobility and future district scenarios in the coming analysis.
