ATTACHMENT 1 Overview of the Initial Vision Scenario In 2008, Senate Bill 375 (Sternberg) was enacted. The state law requires that our Regional Transportation Plan contain a Sustainable Communities Strategy (together, Plan Bay Area) that integrates land -use planning and transportation planning. For the 25 -year period covered by Plan Bay Area, the Sustainable Communities Strategy mustlidenfy areas within the nine - county Bay Area sufficient to house all of the region's population, including all economic segments of the population. It must also attempt to coordinate the resulting land -use pattern with the transportation network so as to reduce per capita greenhouse -gas emissions from personal -use vehicles (automobiles and light trucks). The Initial Vision Scenario for Plan Bay Area is a first -cut proposal that identifies the areas where the growth in the region's population might be housed. This proposal builds upon a rich legacy of integrative planning in the Bay Area. For over a decade, the region and its local governments have been working together to locate new housing in compact forms near jobs, close to services and amenities, and adjacent to transit so that the need to travel long distances by personal vehicle is reduced. Compact development within the existing urban footprint also takes development pressure off the region's open space and agricultural lands. We have referred to this type of efficient development as "focused growth," and the regional program that supports it is called FOCUS. (See Table 1.) Planning for New Housing and Supporting Infrastructure The Initial Vision Scenario is constructed by looking first at the Bay Area's regional housing needs over the next 25 years. This analysis was performed using demographic projections of household growth, It is not a forecast of the region, and does not take into account many factors that constrain the region's supply of new housing units, such as limitations in supporting infrastructure, affordable housing subsidies, and market factors. The principal purpose of the Initial Vision Scenario is to articulate how the region could potentially grow over time in a sustainable manner, and to orient policy and program development to achieve the first phases of implementation. Under the assumptions of the Initial Vision Scenario, the Bay Area is anticipated to grow by over 2 million people, from about 7,350,000 today to about 9,430,000 by the year 2035. This population growth would require around 902,000 new housing units. The Initial Vision Scenario proposes where these new units might be accommodated. (See Tables N12 and maps.) This Initial Vision Scenario is designed around places for growth identified by local jurisdictions. These places are defined by their character, scale, density, and the expected housing units to be built over the long term. Using "place types," areas with similar characteristics and physical and social qualities, ABAG asked local :governments to 1
