Reflections on the 1101 Process in Blount County, Tennessee

Maryville appointment of the planning commission member may be seen as beingassociated with both city and county governments. The remainder were nominallyindependent. The county government was thus a distinct minority in representation onthe Coordinating Committee.Population Projections: One of the basic planning inputs required by Public Chapter1101 was population projections. Projections were provided by the University ofTennessee (UT). The local governments were given the opportunity to contest theprojections, and to provide alternative figures for the 1101 process.The UT projections (all rounded to nearest 100) showed Blount County growing to124,000 by the year 2020. The county contested the projections, supplying its ownprojected population of 136,000. The City of Alcoa was projected by UT to grow to8,800 by the year 2020. The City of Alcoa also contested the UT projections, supplyingits own projected population of 15,000. The other towns and cities accepted the UTprojections as follows: Maryville – 32,600; Louisville – 1,800; Friendsville – 1,300;Rockford 1,000; and Townsend – 600. Based on locally accepted projections, the cityproportion of population was expected to grow from about 35 percent in the year 2000 toabout 38 percent in the year 2020.Population Density: Population density was a major defining characteristic of the threegrowth plan areas, with Urban Growth Boundaries being projected high densitydevelopment, Planned Growth Area being projected moderate to high density, and RuralArea being projected low to moderate density. Public Chapter 1101 did not provideguidance on how density would be applied at the local level. It was assumed that eachlocality would need to define density categories for local planning application.There was no formal agreement on what high, moderate and low density developmentwas in Blount County for the purpose of defining the three required areas. The generalconsensus held that areas of high density development would be defined by reference to ahigh level of urban services, most particularly sewer. The County offered its ownanalysis of density categories based on criteria for approval of subdivisions in the countyplanning commission.High density was defined in relation to provision of sewer, which would allowsubdivision densities greater than 1.5 units per acre. Note that under County regulationsthe maximum density on sewer was about 4.6 units per acre, under Maryville regulationsthe maximum density was 6.2 units per acre, and under Alcoa regulations the maximumdensity exceeded 12 units per acre.Moderate density was defined as a range from one unit per three acres to 1.5 units peracre. This was based on informal observation that most non-mountainous developmentin the county on septic systems was within that density range. The standard fordevelopment on individual septic systems was similar across all jurisdictions, being aminimum lot size of between 20,000 to 25,000 square feet if on public water.Blount County 1101 Growth Planning Process Page 3 of 14
