Vegetation Management Plan
As a rule, no. This also includes skipping over culverts and such. If it is determined that control is needed along road shoulders, or if state listed noxious weeds are in riparian areas, then only approved chemicals are used but no residual ones. Application is done by hand depending on the situation.
Any tree which obstructs sight distance at any point is removed. Also, if a tree has excessive lean that may pose a hazard in the future, it will be removed. We will work with the landowner where possible, but roadway safety is the main concern.
Chemicals approved for use on water are sprayed on vegetation growing along road shoulders. A residual chemical, approved for use up to the water's edge, is used to prevent plant re-growth during the growing season. This chemical binds itself to the upper soil profile and does not travel. Water approved chemicals are also used for broadleaf plants.
Mowing cannot remove grass from pavement edge. Also, mowing costs almost $700/day regardless of distance covered.
Asphalt must stay dry or well drained to maintain integrity. If it has been determined that shading vegetation keeps the roadway wet, which can allow ice build up, it will be removed.
Grass rooting at the edge of pavement will result in the cracking of the road surface. Also, sod buildup does not allow water to runoff road lending to further the degradation of the roadway.
Due to the constantly changing dynamics of vegetation management, this document must be flexible enough to adapt to any situation and be updated accordingly.
The roadway is sensitive to small fractures on the outside edges. Dust and debris that settles within these cracks provide a foothold for vegetation. Treating this marginal area will help keep the roadway from cracking due to plant growth.
