Environmental Planning


Roadside Resources

Roadside design and management is integral to efficient highway planning, design, operation, and maintenance. These areas must be managed for multiple uses and benefits, including safety considerations, signage, utilities, water quality, aesthetics and habitat. Decisions on how to balance and manage these interests affects the appearance of the roadside and the user experience. Properly designed and managed vegetation complements the functions of the roadway, integrates the roadway into the surrounding landscape, and has a positive effect on the traveling public.

Roadside Resources coordinates with and supports programs throughout ADOT, including:

ADOT’s goal for roadside management is to follow Integrated Vegetation Management (IVM) practices. IVM promotes the establishment of low-maintenance beneficial vegetation and the suppression of unwanted vegetation through the integration of biological, cultural, manual, mechanical, and educational methods. Chemical controls are used only when needed. IVM uses plant growth characteristics, principles of plant succession, and knowledge of natural and human-related factors affecting environmental change to achieve management goals, while minimizing impacts on the environment.
