OPERATIONAL STANDARDS Turf Maintenance Turf shall be maintained in a healthy, superior condition with a crisp, clean appearance at all times, with uniform density and no bare spots (Contractor is responsible for fixing bare areas due to scalping from the mower). For areas identified for maintenance at 42 weeks/year, turf shall be mowed a minimum of once per week during the growing season (March through November). During the months of December through February, turf shall be mowed on an as-needed basis. The City shall determine the mowing schedule. Bruising or rough cutting of grass shall not be permitted. Mower blades shall be sharp and properly adjusted so that turf is cut to a uniform height. Scalping will not be permitted. Grass cuttings which clump or windrow shall be removed immediately. Mowing patterns will be changed weekly or however necessary to avoid rutting. Mower discharge of clippings shall be pointed down in a safe direction to prevent injury. Grasscycling shall be employed for all turf areas except as noted in Attachment 6 (see ABay- Friendly Landscaping Guide to Grasscycling, available at www.BayFriendly.org). Grasscycling requires an integrated management system of irrigation, mowing height, and mowing frequency. Turf shall be mowed at a height appropriate for the species of the turf: Tall fescue 2-3" Bluegrass, ryegrass, red fescue 1.5-2.5" Dichondra, Bermuda grass 0.5-1.0" Mulch leaf litter with mowers as needed throughout the fall and winter months. Large concentrations of leaves may require pickup. Rakes are preferred for leaf litter removal over blowers. Leaf litter shall not be allowed to accumulate to the point that it will damage or kill turf. Leaf litter that is removed from turf shall either be chopped and used on-site, or transported to a plant debris recycling facility. All turf areas shall be cleanly edged to the inside (turfside) edge of any concrete or asphalt interface. All turf growing along public sidewalks and walkways shall be edged to maintain a crisp, clean edge along all such structures. Grass shall also be kept from overgrowing sprinkler heads. Edging shall also include trimming grass around trees, poles, utilities, and any other concrete pads within or immediately adjacent to the turf areas. Edging shall be done once per month during the months of November through March, and every two (2) weeks during the months of April through October. Edging shall be done by the use of power edgers or by hand. Soil sterilants or other herbicides shall not be used for edging. Care shall be taken to avoid damage by mowers to tree trunks, irrigation heads and any other utilities, facilities or structures within or adjacent to turf areas. Any damage caused by the Contractor's negligence shall be repaired at the Contractor's expense. Prior to mowing, the NPSA 50016-Citywide Turf Pacheco Brothers Page 16 of 30
