Title: Local Road and Street Need Assessment
Project Researcher: Katie Zimmerman, Applied Pavement Technologies
Project Manager: Dave Huft
Research Period: 8/12/1998 - 1/31/1999
Status:
Cost: $24,993.00

Problem Statement: The South Dakota state legislature has begun an interim study of needs and funding for state and local roads and highways. Although information about need and funding levels is readily available for the state highway system, similar information for local roads is either incomplete or outdated. A 1991 study performed by the South Dakota Department of Transportation estimated funding needs on the county highway system, but construction and maintenance costs have inflated since that time. SDDOT estimated needs on the urban federal-aid system in 1993, but the estimate did not include needs on other urban streets. Because federal-aid streets are only found in the state's thirteen Class 1 cities, the estimate excluded most of the state's smaller cities and towns. Finally, no estimate has been performed for the county secondary and township road systems. (The term county secondary refers to roads that would normally be township responsibility, but where no organized townships exist, are the responsibility of the county.)

The estimates performed to date have also excluded costs not directly related to construction and maintenance of road surfaces and bridges, such as winter maintenance, vegetation control, drainage, signs, and pavement markings. Without these costs, the total need has been underestimated.

Research is needed to reliably estimate total funding needs on all local roads, streets, and bridges, and to compare those needs to available funding.



Findings:

Research Objectives:
1  To develop a credible estimate of annualized, statewide, need for construction, rehabilitation, and maintenance of all local roadways and bridges in South Dakota.
2  To develop a credible estimate of local governments’ annualized, statewide need for other maintenance activities, such as winter maintenance, vegetation control, signing, and pavement markings.
3  To identify differences between total funding needs and present funding levels.

Research Tasks:
1  Meet with the project’s technical panel to review project scope and work plan.
2  Review and verify the construction, rehabilitation, and maintenance guidelines developed in prior research for South Dakota’s local roads and streets.
3  From information available from state and local agencies, compile an inventory of local roads, streets and bridges in the state’s local county, county secondary, township, and city jurisdictions.
4  Characterize the current condition of local roads, streets and bridges from information available from state and local agencies.
5  Estimate current unit costs of construction and maintenance activities for road surfaces and bridges from information available from state and local agencies.
6  Develop a 20-year estimate of funding needs for construction, rehabilitation, and maintenance of road surfaces and bridges by jurisdictional system, and derive annualized costs.
7  Determine the backlog of needs on local government roads, streets and bridges by jurisdictional system.
8  Estimate annual funding needs for other maintenance activities from information available from state and local agencies on current expenditures for these activities.
9  Compare total annualized funding needs to current levels of expenditure for all construction, rehabilitation, and maintenance of roads, streets and bridges by local government agencies.
10  Prepare a final report and executive summary of the literature review, research methodology, findings, conclusions, and recommendations.
11  Make an executive presentation to the SDDOT Research Review Board at the conclusion of the project.
