Roadside Spraying Program
Roadside spraying in SDG takes place in May and June of each year. Spraying occurs from the edge of the gravel shoulder to within one metre of the property limits and uses selective, Government of Canada-approved herbicides to control the growth of undesirable vegetation. The contractor performing the work is fully licensed. Spraying occurs in areas identified during regular weed audits.
If you do not want the right-of-way in front of your property to be treated :
- You must post “NO SPRAY” signs at the start and finish of your property, similar to the image on this page.
- The “NO SPRAY” signs must be at least one foot by two feet and located three feet from the edge of the gravel shoulder. Signs must be one foot above any vegetation so that it is easy to see from the road.
Spraying will not occur if the ditch is mowed on a regular basis (maintained as a lawn). To ensure that spraying does not occur, we recommend you install a sign regardless of how the ditch is maintained.
To help us keep track of your area of concern please identify where you've installed a "No Spray" sign on this map:

Guide Rail Spraying Program
In 2023 the County will be completing limited guide rail spraying where health and safety concerns prevent staff from weed trimming. This work will take place through the month of June and make use of non-selective herbicides. The map showing the location of the planned guiderail spraying will be posted below on or before June 13, 2023.
Current Progress (2023)
Roadside spraying is expected to start on May 15, 2023. The daily progress log can be found here: DAILY LOG.
Guide rail spraying is expected to start on June 13, 2023.
Vegetation Management in SDG
SDG is required to keep its roadsides free of undesirable weeds and maintained in a responsible manner. Transportation Services manages roadside vegetation by mowing, brushing, tree-cutting and weed-spraying. In the spring, the County will spray areas where a significant growth of noxious weeds is occurring. The County also mows unmaintained ditches from the shoulder of the road to the fence line once per year (depending on the steepness of the ditch and weather conditions). Mowing begins in June and finishes in October. Tree and brush trimming occurs from spring to fall.
