Turf care shall be differentiated by the two types of turf - "Casual Turf' and <br />"Sport/Priority Turf (see site maps in Attachment 5 that identify the areas for each <br />type of turf). The Contractor shall maintain mowers that provide a smooth, even cut <br />without ridges or depressions and without tearing of the leaf blades (caused by <br />unsharpened mower blades). Mowing shall be performed at the speed the mowers <br />manufacturer specifies to maximize quality of cut. Mowing shall be performed with <br />straight and flowing patterns approved by the Director's Representative. The <br />emphasis will be on quality mowing vs. speed and unprofessional patterns. From <br />time to time the Director will direct the Contractor to change mowing pattern to <br />minimize rutting and compaction. <br />a) Casual Turf Mowing <br />All "casual" turf (non-sport/priority turf) shall be mowed: 1) weekly May <br />I through October 31 and, 2) every other week November 1 through <br />April 30 . The Contractor shall use a tractor powered reverse flail mower <br />for the larger open turf areas, a 52" mower and a small walk behind <br />mower for areas between trees and other park amenities. The Director <br />shall determine height of cut. String trimmers are not allowed for <br />mowing turf. Any visible clippings shall be collected and disposed of <br />pursuant to SAMC Chapter 16. <br />b) Priority Turf Mowing <br />All "sport/priority" turf as described in Attachment No. 5 shall be <br />mowed once a week all year. Any visible clippings shall be collected <br />and disposed of pursuant to SAMC Chapter 16. The Contractor shall <br />mow the sport/priority turf areas at 1/4" to 1" using a power driven <br />fairway reel mower and a walk behind reel mower along skinned infield <br />brickdust areas, turf infields, turf infield foul areas, soccer/football fields, <br />soccer/football out of bound areas. The Director's Representative shall <br />direct the Contractor to mow the sport/priority turf lower than 3/4" to 1" if <br />necessary. Note that the ball diamond infield maintenance sub- <br />contractor shall be responsible for mowing turf infields and other <br />designated ball diamond turf areas. (see Attachment 1). <br />c) Edging and Detailing <br />All edging shall be performed with the use of a McClain's edger or <br />approved substitute. Stick edgers are not allowed. Contractor shall edge <br />all turf adjacent to all improved hard surfaces such as concrete, <br />decomposed granite, asphalted concrete paved areas. Edging/detailing <br />shall be performed at the same time mowing occurs. Chemical detailing <br />of turf may occur with the Director's approval. If chemical detailing is <br />performed, the Contractor shall use the string trimmer to remove the <br />treated turf within one (1) week after symptoms of phytotoxicity become <br />recognizable. <br />(1) The Contractor shall use the McClain's edger, or approved <br />substitute, to edge straight lines along fences, walls, or long <br />flowing arcs. The Director's Representative may require the <br />Contractor to use string lines to edge straight lines if the <br />14 <br />
