. Development of Growth Scenarios The two growth scenarios used in the land use and transportation analy- sis were modifications of concept scenarios generated in the study's first year. Modifications included: incorporating approved and pending devel- opment proposals, and adjusting scenarios to reflect immediate develop- ment trends and pressures. The Coalition requested these modifications to optimize use of findings and conclusions for current public policy and public invesbnent discussions among Coalition cities and local govern- ments and state /regional agency partners. Scenario Characteristics The conventional growth scenario is characterized by single land use development, low densities, and auto-orientation. Site designs have low floor to area ratios and surface parking. Residential subdivisions have simi- lar housing types organized around cul-de-sacs. e The Coalition growth scenario is characterized by walkable, mixed-use centers that cluster development in areas identified as transit corridors or transitways or in areas with potential for higher levels of transit service in the future. Densities in these centers are generally higher in the mixed-use core and lower in the surrounding area where land is oriented to either residential or commercial/ industrial uses. Residential subdivisions have a mix of housing types and densities. MAU. "AnMEHT$ Conventional Suburban Design ..,"'", .
