The core of Westchester is the 5,162 acres between the two western-most major highways and between sw 40 street and sw 8 street. In the 1990s, this relatively affluent neighborhood was positioned to incorporate as were other neighborhoods which felt they were paying more in taxes than they were receiving in services. The 1996 Board of County Commissioners created Community Council 10, a quasi-governmental entity which provided a structure to address local zoning issues and to provide training for the expertise necessary to future municipalities (Moreno, 2006). The boundaries of Community Council 10 were drawn to limit the number of Councils within the county, and as such, were inclusive of several then existing neighborhoods. Although the Census Bureau recognized places such as Westchester and Coral Terrace, Community Council boundaries were more inclusive and at times exclusively drawn according to the unincorporated area within County Commission Districts. The current boundaries of the Council include Westchester, Coral Terrace and several other neighborhoods, diluting the sense of community in each of these neighborhoods. Though Westchester encompasses the homes of more than 30,000 people, there are rarely more than 15 people at an association meeting (Zayas 2004). One of the association's problems in the past has been trying to unite residents with different ethnic backgrounds and lifestyles.
