Letter from A. F. Potter to Carl Hayden regarding W. W. Bass's livery permit. Bass's fee to maintain the roads has been reduced to $50 per year, but he will still need to keep his business at least a hundred feet from the Grand Canyon rim so as not to disturb visitors.

Sustainable housing strives for diverse, healthy, affordable, socially inclusive, resource-efficient, and culturally sensitive housing. This report’s current state assessment is based on five goals of sustainable housing, derived from sustainability and livability principles: meet demand with adequate housing options; provide sufficient quality of housing and promote healthy housing conditions; secure affordability of housing; conserve natural resources in homes; and maintain valuable cultural and historical character.

The transition strategy presented in this report describes a set of coordinated interventions necessary to create sustainable housing in the Midtown District. The current state of housing in the District is not sustainable for housing options and affordability. There is a clear need for effective interventions to achieve a sustainable state of housing in the future.

The transition strategy in this report is a set of coordinated interventions necessary to create sustainable green systems in the Midtown District. Sustainable green systems strive for fully functional stormwater, biodiversity, and resource management practices, as well as sustainable levels of thermal comfort, energy efficiency, and access to green space. The assessment of green systems indicates concern for high temperatures, low vegetation, and insufficient stormwater management. This strategy is based on achieving four specific goals of sustainable green systems, derived from sustainability and livability principles (HUD, 2009). Goal 1. Reduce stormwater loads and harvest water onsite; Goal 2. Reduce potable water consumption; Goal 3. Reduce daytime temperatures; Goal 4. Increase green systems benefits to health, mobility, and the economy.
