Transportation Demand Management

TDMEVAs part of his Vision for a Green City document, Mayor Ralph Becker initiated petitions to revise parts of the Salt Lake City Zoning Ordinance to incorporate policies that encourage sustainable development. The request included a recommendation to make changes to the City’s zoning ordinance with regard to off-street parking regulations. The goal of the proposed text amendment is to integrate transportation demand management (TDM) strategies which meet a broad range of sustainability goals related to mobility and transportation. Examples include: reducing air, water and noise pollution; promoting alternative transportation options and commuting choices; and reducing the cost of road construction and maintenance. Changes to the zoning ordinance include the in the introduction of limits to parking throughout the city, increased bicycle parking requirements, electric vehicle parking requirements, and the creation of a new Transportation Demand Management (TDM) system intended to incentivize the reduction of parking and encourage the development of infrastructure and programs that meet the transportation-related goals of the city.

On November 12, 2013 the City Council adopted Ordinance No. 62 putting these changes into effect. Click here to review the recently adopted ordinance
