The Metropolitan Transportation Commission (MTC) and the Association of Bay Area Governments (ABAG) have developed a plan over the past several years, and the draft is now out for review. The news release is here: https://www.planbayarea.org/news/news-story/draft-blueprint-released .
The main issues being addressed are transportation and housing (and equity in general), as well as resilience, including sea-level rise mitigation. The plan is based on an economic model showing growth from 2020 (7.93 million people in 2.76 million household, with 4.08 million people employed) to 2050 (10.33 million people in 4.04 million households, with 5.41 million employed). It projects/assumes increased graying of the population (age 65 and over), and increased income inequity (low and high income percentages both increasing, middle incomes decreasing).
The top-level site for the plan has links and further information.
A four page flyer summarizing the draft plan is also available. Public comment opens today (July 10th) and closes on August 10, 2020. A 3 minute video about the plan is available on the website, as well as a survey seeking opinions on priorities and types of projects. The survey should take about 5 minutes to fill out.
