Integrated roadside vegetation management plans

Our maintenance crews use integrated roadside vegetation management (IRVM) plans to apply the right tools, techniques and timing to care for the soil and greenery alongside highways. We update our training programs yearly with successes and lessons learned and we welcome public input.

Integrated roadside vegetation management plans

Each plan lists intended routine maintenance activities, weed control priorities, sensitive area locations and other relevant information. They also include a record-keeping system of mapping and tracking work through our Highway Activity Tracking System (HATS).
