Article 3 — Work Methods
3.1 Requirements. Set mower cutting height 5–7 in. or as directed.
Perform mowing sequence as directed or approved. Ensure wet ground is not mowed when rutting can occur, unless otherwise approved. Do not mow designated non- mow areas. Remove debris ejected onto the roadway immediately . Remove mowed grass from roadway when determined to be a hazard. Hand- trim around fixed objects within mowed area. Complete hand trimming on each roadway within 24 hr. of mowing. Ensure trees and shrubs are not damaged. Restore appurtenances damaged by mowing operations in accordance with Article 7.17. , “Contractor’s Responsibility for Work.” Ensure stands of wildflowers are not mowed before seeds have matured, unless otherwise directed.
3.2 Mowing Types .
3.2.1 Strip Mowing. Mow a strip of vegetation along edge of pavement or unpaved shoulder shown on the plans.
Mow to provide sight distance at horizontal curves, intersections, driveways, and ramps. Mow to right of way line where specified. 977 Mow around appurtenances within the strip width. Mow entire right of way under bridges and in drainage channels. Provide a 6:1 transition between the strip width and other areas requiring a different width. Mow the entire width of medians and outer separations ( e.g., areas between mainlanes, ramps, and frontage roads), except for non- mow areas.
3.2.2 Full-Width Mowing. Mow vegetation in the entire right of way, except for non- mow areas.
3.2.3 Spot Mowing. Work requests are made on a callout basis. Begin mowing designated areas within 48 hr. of
notification unless otherwise shown on the plans.
3.3 Washing Mowing Equipment . Pressure wash mowing equipment before the equipment enters or leaves
designated areas shown on the plans. Notify the I nspector before washing the equipment. The I nspector must approve the washing locations so seed and plant material is contained.
3.4 Mowing Season. The Engineer may adjust the listed dates and timelines as needed.
3.4.1 Spring. Delaying spring mowing allows wildflowers to set seed for repopulation.
3.4.2 Fall. Delaying fall mowing until October 15 allows full use of the Department’s herbicide program.
