In the case of the TransNet extension, which covers 40 years, a perceived lack of flexibility on the implementation of the project lists renders the Draft 2015 Regional Plan less dynamic and results in communities that lack the transportation and housing choices and overall land uses to address the environmental and economic needs of the region’s population. Fortunately, TransNet is not as inflexible as some perceive it to be. While it is highly prescriptive, SANDAG has wide discretion in terms of the scope and timing of the projects themselves. Paired with the aforementioned flexible state and federal sources, SANDAG can implement TransNet to improve its transportation system in a sustainable and economically dynamic manner.
