A. All City Systems <br /> This subsection provides a number of broad findings that are representative of the experiences of all <br /> Minnesota cities, not exclusively large or small cities. The findings presented in this subsection also <br /> are applicable to city streets funded predominantly with locally generated property tax revenues, and <br /> roadways supported by Municipal State Aid. <br /> <br />Findings <br /> <br />#A-l: Maintenance costs increase as road systems age. <br /> <br />Figure 20 illustrates the <br />relationship between the <br />age of a roadway system, <br />the condition of the <br />pavement surface, and <br />the cost to improve it. <br />The cost to improve a <br />roadway surface <br />increases as the <br />pavement surface <br />deteriorates over time. <br />Put another way, timely <br />maintenance is not only <br />effective in improving <br />roadway surfaces, but it <br />saves money over the <br />long run. <br /> <br />Pa. ,,e~t e~t t L ire <br /> <br />This relationship is <br />widely accepted, and <br />was reflected by many of the comments and the data provided in the 2002 City Road and Bridge <br />Funding Survey. Figures 21 and 22 on the following page reflect the road construction vs. <br />maintenance spending trends for 32 large cities (populations over 5,000 and MSA eligible) and 108 <br />smaller cities (under 5,000) that were reported in the survey. <br /> <br />23 <br /> <br /> <br />
