• Abstract:
  In Iowa, there are currently no uniform design standards for rural and suburban subdivision development roadways. Without uniform ; design standards, many counties are unable to provide adequate guidance for public facilities, particularly roadways, to be constructed ; as part of a rural subdivision development. If a developer is not required to install appropriate public improvements or does not do so ; properly, significant liability and maintenance expenses can be expected, along with the potential for major project costs to correct the ; situation. Not having uniform design standards for rural and suburban subdivision development improvements in Iowa creates situations ; where there is potential for inconsistency and confusion. Differences in the way development standards are applied also create ; incentives or disincentives for developers to initiate subdivision platting in a particular county. ; With the wide range of standards or lack of standards for local roads in development areas, it is critical that some level of uniformity is ; created to address equity in development across jurisdictional lines. The standards must be effective in addressing the problem, but they ; must not be so excessive as to curtail development activities within a local jurisdiction. ; In order to address the concerns, cities and counties have to work together to identify where growth is going to be focused. Within that ; long-term growth area, the roadways should be constructed to urban standards to provide an easier transition to traditional urban ; facilities as the area is developed. Developments outside of the designated growth area should utilize a rural cross section since it is less ; likely to have concentrated urban development. ; The developers should be required to develop roadways that are designed for a minimum life of 40 years, and the county should accept ; dedication of the roadway and be responsible for its maintenance.
