The Arizona Department of Transportation (ADOT) Roadway Departure Safety Implementation Plan (RDSIP) has identified tree removal as a feasible countermeasure to reduce roadway departure crash frequency or severity. Previous ADOT work has identified locations for tree removal, and activities to conduct this work are underway. To test the safety effectiveness of removing the trees, ADOT intends to conduct statistically rigorous before-after safety effectiveness analysis to estimate state-specific crash modification factors (CMFs).

The Arizona Department of Transportation’s (ADOT’s) process for working with Local Public Agencies (LPAs) in the development and delivery of their transportation projects has evolved over the years. Recent changes in Arizona’s economy have reduced the distribution of state funds for local transportation projects, which has increased the demand for federal funding sources. In response to the anticipated increase in LPA projects desiring the use of federal funds and the continuing need to meet state and local transportation requirements, this updated manual highlights the steps necessary to capably deliver LPA projects in compliance with federal, state, and local requirements.

The ADOT Local Public Agency Projects Manual has been a collaborative effort among the various Divisions, Groups, and Sections within ADOT, as well as the Federal Highway Administration (FHWA) Arizona Division, with input from LPAs. ADOT would like to express sincere gratitude to Logan Simpson Design Inc. for successfully facilitating that effort and for their contribution to the production of this manual. Their hard work and in-depth coordination with ADOT and FHWA staff has been invaluable to the preparation of this manual.
