Parking Lot Map Boundary Methodology<\/h1>\n\n\n\n

Zoning boundaries for various cities were often irregular, lacked a definitive form, transcended physical boundaries, and had opposing zones located within each other. To solve this, the following method was developed to create boundaries that most accurately reflected the zoning boundary and the most valuable land in the city.<\/p>\n\n\n\n

\n\n\n\n

Districts Chosen:<\/h3>\n\n\n\n

The zoning district(s) that allow for the densest development throughout the city were mapped. This was often the Downtown or Central Business District boundary, which accounted for about two-thirds of the total boundaries created. Please see the bottom of this page to view all districts chosen for a particular city.<\/p>\n\n\n\n

Use of Physical Boundaries:<\/h3>\n\n\n\n

Many cities have dense zoning districts that transcend physical boundaries, such as interstate highways, rivers, and railroads. Areas that are separated from the downtown have drastically different parking land use than that of the Central Business District area. Many times this is an industrial area that is rezoned to be redeveloped or a single-family residential area with the same intention. To prevent these areas from being measured all areas outside of hostile boundaries that disrupt the central business district were excluded from the map boundary. Twenty-one cities had interstate highways, three had rivers, and three had interstate highways and rivers as part of their boundaries. This method hopes to make all cities comparable by mapping their most valuable, centrally located, and easily developed areas in the city. <\/p>\n\n\n\n

Fig 1.<\/strong> Depicts the difference in demand for land on the east and west sides of Interstate 405. West of the Central Business District has five times as much parking. <\/p>\n\n\n\n

Creating a Standard Form for Boundaries:<\/h3>\n\n\n\n

All zoning districts mapped must be contiguous. The main part of the district must physically border a block on one side of the same zone to be mapped. Zones that were catycorner to a like zone were excluded and also zones that were not connected physically were excluded. All zones that were fully surrounded by the main zone were also included. <\/p>\n\n\n\n
