E. Development Pattern Louisville’s development pattern can be broadly characterized into three zones radiating outward from the Ohio River and downtown Louisville (See Figure III.E.1: Generalized Land Use Map). The innermost zone, generally circumscribed by the Interstate 264 loop and the Ohio River, is largely built out and contains the densest and oldest development in the City. Louisville’s downtown is the hub of this zone. The second zone, from Interstate 264 to the loop formed by the Gene Snyder Freeway, is characterized by a more suburban pattern of development with vacant land interspersed among residential and industrial land uses particularly in the outer part of the zone. The land use pattern of the outermost zone, from the Gene Snyder Freeway to the City boundary, is distinguished by a more rural road network supporting lower density residential development and significant tracts of vacant land. Commercial uses in Louisville are concentrated in downtown Louisville and along major arterials (such as Dixie Highway, Preston Highway, Bardstown Road, and Shelbyville Road) which radiate outward from the hub. According to a survey by Jefferson County DPDS, approximately 96,940 acres of land or 40 percent of the County was undeveloped in 1992¹². Of this total, approximately 56 percent was characterized by development constraints such as shallow depth to bedrock, steep slopes, hydric soil conditions, and/or susceptibility to flooding. Most of the remaining vacant land was concentrated in outer Jefferson County, especially the Floyds Fork Drainage Area. Facilitated by a readily available infrastructure of roads, sewer lines, and water lines, development within the inner part of Louisville has experienced extensive residential, commercial, and industrial growth. Vacant tracts of land are still found interspersed in the predominant pattern of developed land uses, often in areas characterized by sensitive environmental resources such as stream corridors and hydric soils. To date, this land use pattern is less prevalent in the outer part of Louisville due to less extensive infrastructure (including limited public sewer service in the Floyds Fork drainage area) and lesser demands for development. However, growth pressures are increasing in this area as evidenced by the suburban homes which have been constructed on large lots along many roadways in the past 30 years. On the other hand, there is also indication that this growth pattern has changed with the increase in smaller households and more interest by millennials in living in a vibrant urban environment and more demand for apartments. Park and open space resources are part of the existing pattern of land use, affording visual relief from the surrounding urban fabric, providing recreational and environmental benefits, and helping to define neighborhood boundaries. Of particular significance is the historic system of Olmsted-designed parks and parkways, which was originally conceived as an interconnected open space network providing multiple recreational, environmental, and visual benefits. As the last major park system Frederick Law Olmsted, Sr. designed, Louisville’s Olmsted parks are considered his most mature park system and area priceless open space resource for Parks and Recreation System Master Plan | III.
