SECTION IV EDGING & DETAILING A. General Specifications 1. All edging shall be performed with the use of a gas-powered blade edger or CR-approved substitute. Stick edgers shall not be used. 2. Chemical edging is allowed along edges such as trees, fence lines, curbs, etc., as directed by the CR. The contractor shall not use chemical edging in areas not authorized by the CR. 3. If chemical detailing is performed, the Contractor shall use a string trimmer to remove the treated vegetation within one (1) week after symptoms of phytotoxicity become recognizable. a. Plants (i.e. trees, shrubs, groundcovers, annuals) with noted phytotoxic damage from an herbicide edging treatment shall be removed within one (1) week of observation and replaced with like-sized plants. 4. The contractor shall detail turf no further than 12 inches away from all hard surfaces, including walls, fences, curb lines, roadways, pathways, and landscape surfaces (e.g. trees, shrubs, beds, etc.). a. Detail lines shall be made straight and shall be maintained straight. 5. The contractor shall supply, at Contractor's own expense, replacement plants to reduce any existing bare soil areas along walls and fences that are wider than 12 inches that have been caused by the Contractor's neglect. 6. Edging/detailing shall be performed at the same time mowing occurs. 7. All edging/detailing shall be performed with the use of a McClain's edger or an approved substitute walk-behind or fixed blade stick edger. The contractor shall edge all turf adjacent to all improved hard surfaces such as concrete, decomposed granite, asphalted concrete paved areas, pavers, etc. 8. The Contractor shall detail around trees, along walls/fences, and other amenities first using a sharpened shovel cut to establish a concentric round circle around trees, poles, etc. Once the initial detailed circle is established a string trimmer may be used to maintain the circle. Should the circle begin to deform, the Park Services Inspector Supervisor shall direct the Contractor to repeat the detail process. Shovel-cut detailing shall be repeated as often as necessary to maintain crisp evenly round/straight lines. In the event that the circle becomes too great, the DR shall direct the Contractor to sod the area around the tree at the Contractor's expense to the size instructed by the Parks Services Inspector Supervisor.
