As part of its metropolitan transportation planning activities, SCAG works with transit operators, the region’s transportation planning agencies, and the California Department of Transportation (Caltrans) to develop goals, objectives, plans, and policies to provide effective and sustainable transit options for the region.

One key component of this partnership is the Regional Transit Technical Advisory Committee (RTTAC), which is composed of representatives from Caltrans, the region’s County Transportation Commissions (CTCs), and various transit operators.  The RTTAC provides a forum for the coordination of input in the development of the RTP, the Federal Transportation Improvement Program (FTIP), and SCAG’s Overall Work Program (OWP). Formal relationships and interactions, including RTTAC participation, between the above agencies are governed by a set of Memorandums of Understanding (MOUs) that were executed in 2007, describing each party’s roles and responsibilities in carrying out and supporting the metropolitan planning and programming processes.  These MOUs were executed pursuant to 23 CFR 450.310(b).  The current chair of the RTTAC is Wayne Wassell of Metro, and agendas, minutes and presentations of previous RTTAC meetings are posted below.

Adaptation and Resilience Planning

For Providers of Public Transportation

The planet’s climate is changing, and this is producing impacts on local transportation systems such as sea level rise, changes in temperature and precipitation, and increased flood risk. In order to maintain the resilience of the transportation system in light of these challenges, local agencies will have to analyze the potential impact of these challenges in their long range capital planning.
