It also delves into the dynamics of communication and cooperation with private landholders of Southwest Boise suburban neighborhoods, and the importance of easement programs that make a retrofit of suburbia possible. Using easement programs that seek to benefit all parties involved, new easements can be formed to serve as pedestrian pathway corridors to provide access to desired destinations. By increasing connectivity through a retrofit of the landscape, the walkability of the area improves, and residents begin to use a safe pedestrian landscape for exercise 4 Introduction Research Question Problem Statement Context and Purpose Research Question Project Goals How can suburban neighborhoods in Southwest Conceptual Framework Boise be retrofit to improve connectivity and walkability in order to reduce automobile-dependence and promote Theoretical Approach healthy lifestyles, by adapting existing easements and utiliz- ing incentive programs to create and maintain new easements?

The goals are as follows: Demonstrate the need and benefits of retrofitting Southern Boise’s suburban neighborhoods to be walkable and amenity-rich. 6 Research and analyze mobility, accessibility, and connectivity to the needs and amenities of residents, to design safe trailway systems. Understand the suburban neighbor’s perspective and needs, finding appropriate accomodation for them in easement programs that seek to create trailways through neighborhoods. Emphasize qualities of walkability and sense of community through biking and walking as alternative modes of transportation, thus promoting exercise and increasing the likelihood of casual interaction between neighbors. Propose the integration stormwater retention techniques, and promote native wildlife and riparian habitat. 7 Conceptual Framework 8 Conceptual Framework The Conceptual Framework diagram, as shown on to allow for easements, and the easements set within 100- the previous page, reveals how all the major concepts of the year flood zones that, due to its flooding nature, are unable Boise Loop Project are interconnected.
