A plan for the development and maintenance of the city of Yuma's roadway system, consistent with the city's 2002 general plan, and coordinated with the city's bicycle plan and the Yuma Metropolitan Planning Organization's regional transportation plan.

An introduction to the impact of conservation alternatives on air quality which will be integrated into the land use and conservation plans. The air quality study is summarized in this memorandum.

The study details the direct and indirect impacts of roads on natural resources, including direct mortality and loss of habitat, physical changes to the topography and hydrology of an area, impacts to habitat, noise, light and other types of pollution, and habitat fragmentation.

The study generally confirms the trends and impacts identified in the February 2001 study "Air Quality in Pima County," and suggests two types of strategies for maintaining air quality and ensuring compliance with federal air quality standards. Potential funding sources and future legislative considerations are briefly discussed.
