| − | ===Performance Expectation===
| |
| − | Vegetation height should be maintained between 6 and 12 inches in fully developed areas and between 6 and 18 inches in undeveloped areas. Slopes greater than 1V:3H (3:1) shall not be mowed unless in urban areas with the proper equipment. Transitions between areas shall be gradual and natural. Chemical and/or mechanical trimming should be done as needed so that vegetation height around signposts, delineators, guardrail, guard cable, etc. is consistent with the mowing height.
| |
| − | | |
| − | ===Performance Measures===
| |
| − | Visual inspections will be conducted on randomly selected tenth-mile segments in the fall to determine if the right of way is being maintained in accordance with the vegetation management policy.
| |
| − | | |
| − | ===Performance Objectives===
| |
| − | Vegetation control may be completed up to at least 30 ft. from the edge of the nearest traveled way with 90% of the areas around objects trimmed or sprayed. 95% of unpaved areas should have proper vegetative cover, not including rock cuts or fill areas constructed predominately of rock. 100% of the right of way should be clear or treated to control noxious weed growth.

| − | ===Performance Objectives===
| |
| − | No tree with a diameter greater than 4 in. at breast height or hardscape shall be within the clear zone as defined in [[231.2 Clear Zones|EPG 231.2]], unless shielded by guardrail. All of the right of way shall be free of hazardous, leaning, or dead trees capable of falling onto the roadway. All signs shall be visible for a distance of 500 ft. on the mainline and 250 ft. on the ramps.

| − | ===Performance Expectation===
| |
| − | Debris and road kill shall be removed from the roadway, shoulders and roadsides to provide a safe road and an attractive roadside. It shall be removed as soon as possible if located on the roadway or a ramp. Debris on the shoulders and within the clear zone shall be removed within 48 hours of notification.
| |
