The SDDOT Noise Analysis and Abatement Guidelines/Policy states that noise abatement measures must be reasonable and feasible. Feasibility deals primarily with abatement and not with avoiding noise impacts. The policy also states that highway traffic noise should be reduced through a shared responsibility with local governments. It states that local governments should use their power to regulate land development in such a way that noise sensitive land uses are either prohibited from being located adjacent to a highway or that the developments are planned, designed, and constructed in such a way that noise impacts are minimized.
The SDDOT, working with local governments, implemented a Highway Access Control process that is being successfully used to educate business and community leaders, developers, and regulatory staff. However, the SDDOT has not worked with local governments to develop policies, ordinances, subdivision regulations, or other processes that can be used to help avoid or abate highway noise and provide cost effective alternatives to the construction of noise barriers. The SDDOT needs to consider a range of options and strategies to educate and encourage noise compatible planning in the vicinity of all highways but particularly new or expanded highways. The Department also needs to develop options for local government so developers assume the cost of noise abatement strategies such as barriers if they choose to develop in noise sensitive locations.
Research is needed to refine the SDDOT Noise Analysis and Abatement Policy, develop procedures, scoping and design guidelines, sample ordinances, subdivision regulations, training materials and other cost effective solutions to deal with the highway traffic noise problems. The research should produce materials that the SDDOT and local agencies can use to provide information to elected officials, public works officials, planners, developers, and the interested public about the problem of highway noise and cost effective responses to that problem. A South Dakota based video that explains noise impacts, avoidance, and mitigation measures should be developed to help identify and explain issues concerning development in noise sensitive areas. Finally, the research should provide scoping, environmental, and design guidelines for use by the SDDOT that includes a review of the impacts of rumble strips, surfacing types and textures for roadways in noise sensitive areas.
