822.3 Vegetation Management for High Profile Areas
From Engineering Policy Guide
These areas include raised medians, islands, roadside parks, commuter parking lots and high-profile areas with considerable pedestrian traffic. These locations require the highest level of vegetation management and cleanliness. Vegetation should be maintained in a turf-type manner with vegetation height maintained between 4 in. and 8 inches.
Typically, this turf should be mowed with walk-behind mowers, lawn-type mowers and line trimmers.
