TYPICAL A. SIGN DETAIL

TYPICAL B. SIGN PLACEMENT

4.0 Routine Mowing of Clear Zone Area

When: As directed by SCPRT Representative.

Where: ROUTINE MOWING (Interstate Welcome Centers) includes the following areas:

• Interstate Shoulders (Welcome Centers) (SECTION 4.01)

• Interstate Signs and Structures (SECTION 4.02)

Frequency: SCDOT will mow the Clear Zone Area, three times annually. The estimated frequency will be determined by SCPRT.

What: All vegetation except trees.

How: Mowing will be performed as described in Sections 4.01 and 4.02 of these specifications.

Vegetation shall be mowed to a uniform height of no less than 2 inches and no more than 4 inches.

Begin mowing at the beginning of the welcome center entrance ramp to the end of the exit ramp segment. This activity shall not result in the deposit of vegetative debris onto the road surface.

4.01 Interstate Shoulders (Welcome Centers)

As shown in TYPICAL C. ROUTINE MOWING (Interstate Shoulders/Roadsides), interstate shoulders/roadsides shall be mowed thirty feet from the edge of the pavement. If fill slopes or back slopes are steep and are within this area, mow to the steep slope and one swath of the mower or not less than five feet shall be mowed on these slopes. This mowing width may be increased when necessary to provide adequate visibility for signs erected by SCDOT, when SCDOT determines that increasing the widths is in the public interest or upon request of the governing body of a county or municipality. This activity shall not interfere in any way with the visibility of any outdoor advertising sign. If the Department of Natural Resources makes an assessment and written determination that vegetation management pursuant [to SC Code of Laws, Section 57-23-800] causes an increase in safety risks because of the attraction of wildlife to a specific area along the highway, then the department may increase the distance from the pavement required to be mowed.

TYPICAL C – ROUTINE MOWING (Interstate Shoulders/Roadsides)

4.02 Intestate Signs and Structures (Welcome Centers)

Vegetation under and around interstate signs and structures within the defined Clear Zone Area shall be mowed at a uniform height to the adjacent mowed vegetation. Mowing at Interstate Information/Guide Signs shall be in accordance with TYPICAL D. ROUTINE MOWING (Interstate Information/Guide Signs).

Mowing will be accomplished regardless of slope or guardrail/cable rail. Interstate mainline sign locations shall be mowed to allow full view by approaching motorists for a minimum distance of 1,200 feet. Regardless of road curvature, this distance (1,200 feet) shall be measured along the pavement mainline from the sign face. Additionally, the area that occurs ten feet behind the sign face and extends ten feet beyond the edge of the sign most distant from the pavement shall also be mowed. Ramp panels shall be cleared to provide maximum sight distance. Interstate Information/Guide Signs do not include logo signs. The sight area for logo signs will be maintained to the routine mowing limits only.

5.0 Basis of Payment

SCPRT agrees to pay the Contractor for satisfactorily completed services. SCPRT may withhold payment for work not performed, unsatisfactory work, damages, etc.
