REPORT OF PROJECT-COMMITTEE ON PLANNING AND MANAGEMENT OF ROADSIDE VEGETATION
PLANTS ALONG HIGHWAYS MAY BE CONSIDERED IN GENERAL CLASSES, THE LOW-GROWING KINDS LIKE GRASSES, LEGUMES, AND VINES, AND THE TALLER-GROWIN KINDS WHICH HAVE WOODY STEMS. WHEREVER MOISTURE CONDITIONS PERMIT, THE LOW-GROWING KINDS ARE THE ONES USED MOST EXTENSIVELY AS A COVER ON ROADSIDES. AS AN EROSION PROTECTION MEASURE, IT IS ASSUMED THT THEY WILL BE ESTABLISHED AS A PART OF HIGHWAY CONSTRUCTION. WOODY PLANTS, ON THE OTHER HAND, BECAUSE OF THEIR GREATER HEIGHT, CREATE A THIRD DIMENSIONAL EFFECT IN THE LANDSCAPE AND REQUIRE MORE SPECIAL DESIGN CONSIDERATIONS. CERTAIN CONSIDERATION OF A GENERAL NATURE APPLY TO ALL KINDS OF HIGHWAYS IN ALL KINDS OF SITUATIONS. THEY INCLUDE THE RELATIONSHIP OF VEGETATION WHICH IS ON THE HIGHWAY RIGHT-OF-WAY TO USE AND VALUE OF PROPERTY WHICH LIES ADJACENT TO THE HIGHWAY; THE USE OF VEGETATION AS A GUIDE TO TRAFFIC MOVEMENTS; THE BASIC CONSIDERATIONS IN USING, OR AVOIDING, PARTICULAR PLANTS FOR PARTICULAR REASONS; AND THE KINDS OF LAWS WHICH ARE DESIRABLE TO EMPOWER STATE AGENCIES FOR THE CONTROL OF VEGETATION ON HIGHWAY PROPERTY. SPECIAL CONSIDERATIONS RELATE TO VEGETATION IN RELATION TO THE HIGHWAY CROSS SECTION, THE PROPER HEIGHT OF FOILAGE OVER THE PAVEMENT, THE SET BACK OF VEGETATION FROM THE EDGES OF THE PAVEMENT FOR DIFFERENT CLASSES OF HIGHWAYS, AND VEGETATION IN RELATION TO CURVES. THESE TOPICS AND THE FOLLOWING MIGHT BE REFERRED TO ONLY WHEN SUCH CONDITIONS ARE ENCOUNTERED: SNOW DRIFTING, VIEWS, PLANTING IN MALLS, PLANTING NEAR BRIDGES, PLANTING AT WAYSIDE DEVELOPMENTS, AND PLANTING IN URBAN SITUATIONS.
