P & R Areas - Roadside Management Office

Integrated Roadside Vegetation Management (IRVM) is a long term approach to evaluating, developing, improving and maintaining vegetation on road rights of ways. The ultimate purpose of any Roadside Vegetation Management program is to provide a safe and healthy roadway, and to improve aesthetics along the county's secondary road system. IRVM is a program for accomplishing these objectives in the most economically and environmentally responsible manner possible. It is based on two principles:

-Refining the use of herbicides, so that the chemicals we use have the greatest effect on the target species and the least effect on desirable vegetation and ground water.
-Preventing weeds through species competition by planting the species best suited to each site.

The IRVM program is based on the belief that every county's approximately 4,000 acres of rights-of-way represent a significant resource worth managing by the most sustainable methods possible to the greatest benefit to the county.
