When constructing plantings directly adjacent to roadways, it is important to avoid obstructing the required sightlines as set out in the MTO Geometric Design Standards for Ontario Highways. Under the standard, there are various types of sightlines such as stopping, intersection, passing and decision sight distances that must be met depending on the scenario at hand. Of the various sightline types, adequate stopping sight distance must be provided at all intersections and roadways so that a vehicle must be able to see far enough ahead to perceive an object, react to it and bring the vehicle to a stop before reaching the object in question. Maintaining intersection sightlines at signalized and non-signalized intersections is also required to allow motorists the opportunity to mitigate collisions at intersections. Depending on the site conditions, the extents of intersection site triangles are prescribed in the MTO Geometric Design Standards for Ontario Highways. It is also important to account for the height of vegetation at each LID site as the height should be coordinated such that drivers are given a reasonable view of the intersection where they can see cross-traffic when approaching the intersection.
