72-20-102. Adoption and codification of critical capacity routes map -- Agreement.
(1) On or before January 1, 2027, the city shall:
(a) enter into an agreement with the department that:
(i) identifies and designates each road within the study area as a tier one, tier two, tier three, or tier four road;
(ii) designates regionally significant highways within the study area as tier one roads for which, except as provided in Subsection (2)(a), the city may not implement a project that includes a highway reduction strategy;
(iii) designates highways within the study area as tier two roads for which the city may implement a project that includes a highway reduction strategy only after the city:
(A) completes a thorough data collection and impact analysis;
(B) completes a thorough community and business engagement campaign that includes engagement with key stakeholders; and
(C) receives approval for the project by the department;
(iv) designates highways within the study area as tier three roads for which the city may implement a project that includes a highway reduction strategy as determined necessary by the city, consistent with the terms of the agreement;
(v) includes plans and timelines for the city to mitigate the impacts of traffic calming measures and highway reduction strategies previously implemented on:
(A) 300 West from 400 South to 900 South;
(B) 200 South from 300 West to 300 East; and
(C) 400 South from West Temple to Interstate 15; and
(vi) the city will continually evaluate roads of all tiers within the study area for safety, efficiency, and effectiveness for all modes of transportation; and
(b) adopt and codify a critical capacity routes map into the city's transportation plans and ordinances.
(2)
(a)
(i) The agreement described in Subsection (1)(a) may allow for implementation of one or more safety improvements on a tier one road described in Subsection (1)(a)(ii), if the safety improvements are primarily intended to enhance the safety of all roadway users and do not materially reduce travel capacity or the number of motorized vehicle travel lanes.
(ii) Before implementing a safety improvement under this Subsection (2), the city shall:
(A) complete a thorough data collection and impact analysis;
(B) complete a thorough community and business engagement campaign that includes engagement with key stakeholders; and
(C) receive approval for the project from the department.
(b)
(i) Where possible, the city shall maintain the width of a vehicle travel lane on a tier one road and tier two road within the study area at a width of at least 11 feet.
(ii) The city may not implement a highway reduction strategy on a tier three road within the study area that permanently reduces the width of a highway lane below 10 feet.
(iii) The department may reject a proposed highway reduction strategy on a tier one road or tier two road within the study area that, in the department's discretion, is not in the best interest of traffic management, flow, or safety.
(c)
(i) Before the city may reduce parking by three or more parking stalls on a block face of a tier one or tier two road within the study area, the city shall:
(A) engage with the stakeholders in the immediate vicinity of the block face to assess potential impacts and alternatives; and
(B) inform the department if the stakeholder engagement described in Subsection (2)(c)(i)(A) results in a determination to reduce parking by three or more stalls.
(ii) In determining whether a strategy has the potential to permanently impact availability and accessibility to on-street parking:
(A) a parking fee or hour restriction is not considered a permanent reduction of parking stalls on a block face; and
(B) if a strategy that reduces on-street parking provides additional parking due to construction or access to a new or existing parking structure or lot, the proposed project is not considered a reduction in on-street parking if the aggregate availability of parking is adequate for existing needs.
(iii) The city shall follow the requirements and guidelines of the agreement described in Subsection (1)(a) with regard to permanent parking reduction.
(d) To develop the plan for mitigation described in Subsection (1)(a)(v), the city:
(i) may engage and consult with stakeholders and the department to assess potential impacts and alternatives; and
(ii) shall obtain approval from the department of the proposed plan for each highway.
(3)
(a) On or before November 30, 2027, and annually thereafter, the city, in consultation with the department, shall provide a written report to the Transportation Interim Committee with an update on the agreement and the status of highway reduction strategies and projects within the study area.
(b) On or before November 30, 2028, the Transportation Interim Committee shall review the reports required in Subsection (3)(a) and determine whether the report should continue.
(4) The city may exercise the city's discretion with regard to any tier four road.
(5) The city shall publish the critical capacity routes map on the city website.
(6) The city mayor and the executive director shall sign and approve the agreement.
