Final Scope

State departments of transportation (DOTs) are shifting their focus from auto-centric, high-speed facilities to multimodal Complete Streets programs to support the Safe System Approach. State DOTs must determine how Complete Streets infrastructure assets are prioritized and maintained once adopted. While recent funding is creating opportunities for constructing Complete Streets, maintaining the infrastructure is more challenging. They present compatibility issues with existing components, serviceability challenges for maintenance crews, and seasonal maintenance operations.

The objective of this synthesis is to document state DOT practices related to the funding and maintenance of Complete Streets projects.

Information to be gathered includes (but is not limited to):

  • Existence of state DOT policies or procedures of Complete Streets;
    • Policies related to equitable distribution of funding for Complete Streets development.  
  • State DOT funding strategies and/or policies, including cost-sharing arrangements, for the design, construction, and maintenance of new and existing Complete Streets developments (e.g., new or widened sidewalks, pavement strips or markings for various users, new bikeways, crosswalk enhancements, pedestrian-scale/bikeway lighting, street furnishings, green infrastructure, wayfinding signage, transit parking, etc.);
  • DOT practices regarding Complete Streets maintenance including:
    • Development of new maintenance practices (e.g., new team designated to perform Complete Street maintenance exclusively, or maintenance by equipment);
    • State DOTs procedures for assessing and prioritizing maintenance of facilities (e.g., call-complaint, systemic, etc.);
    • Maintenance agreements with local entities (private agencies, cities, counties, etc.) and Tribal governments for Complete Street projects;
    • Recruitment policies, special certification, and training programs for maintenance staff;
    • Agreements with the manufacturers for equipment repairs; and
    • Policies for acquiring maintenance materials and equipment (e.g., bikeway sweepers, furnishings and lighting standards, maintenance trucks, temporary traffic control equipment, trailers, flatbeds, etc.).

Information will be gathered through a literature review, a survey of state DOTs, and follow-up interviews with selected DOTs for the development of case examples. Information gaps and suggestions for additional research to address those gaps will be identified.
