2. Edging and Detailing <br />All edging shall be performed with the use of a McClain's edger or approved substitute. Stick edgers are not <br />allowed. Contractor shall edge all turf adjacent to all improved hard surfaces such as concrete, decomposed granite, <br />asphalted concrete paved areas. Edging/detailing shall be performed at the same time mowing occurs. Chemical <br />detailing of turf may occur with the Director's approval. If chemical detailing is performed, the Contractor shall use <br />the string trimmer to remove the treated turf within one (1) week after symptoms of phytotoxicity become <br />recognizable. <br />a) The Contractor shall use the McClain's edger to edge straight lines along fences, walls, or long flowing arcs. The <br />Director's Representative may require the Contractor to use string lines to edge straight lines if the Contractor's <br />staff fails to achieve this quality without this method. <br />b) The Contractor shall detail around trees, along walls/fences and other park amenities first using a sharpened <br />shovel cut to establish a concentric round circle around trees, poles, etc. Once the initial detailed circle is <br />established a string trimmer may be used to maintain the circle. Should the circle begin to deform the Director <br />shall direct the Contractor to repeat the detail process. <br />c) The Contractor shall detail turf not greater than 10" away from walls or fences. Detail lines shall be made straight <br />and shall be maintained straight. The Contractor shall, at his own cost, supply top soil and an approved turf seed to <br />reduce any existing bare soil areas along walls/fences that are greater than 10". <br />d) Fertilization <br />(1) Casual Turf- Contractor shall apply fertilizer twice per year (first week of January and July) per the City's <br />agronomic plan (see Attachment 4). <br />(2) Sport/Priority Turf - Contractor shall apply fertilizer four times per year (first week of January, April, October <br />and with annual renovation) per the City's Agronomic Plan" (see Attachment 4). If no summer renovation <br />occurs, the application shall be applied as determined by the Director. <br />e) Irrigation-all turf <br />(1) Contractor shall ensure irrigation schedules are continually monitored to provide adequate moisture in the soil <br />for healthy turf, and avoid excess wet conditions. <br />(2) Contractor shall not schedule irrigation of sports fields at least 24 hours prior to the mowing process. During <br />cooler periods of the year avoid irrigating 48 hours prior to the mow procedures to ensure a quality cut of the <br />turf. <br />(3) Under normal conditions the contractor shall not schedule irrigation on Friday and Saturday nights to avoid <br />wet conditions during weekend usage. Prior approval will be required to irrigate during weekends to <br />coordinate with reservations. <br />(4) Turf areas shall be watered as required by weather conditions to provide adequate moisture for optimum <br />growth. At no time shall turf areas show a lack of green color or a loss of resilience due to lack of water. If <br />Contractor estimates additional water above and beyond the monthly Estimated Applied Water (EAW) may <br />be needed, he/she shall request approval from Park Services prior to exceeding the monthly irrigation budget <br />as detailed in the Monthly Water Conservation Report Estimated Applied Water (EAW) requirements. <br />Failure to get approval from Park Services prior to exceeding the monthly irrigation budget will result in the <br />Contractor paying for the excess water. <br />(5) When an irrigation system does not adequately provide water to the turf area in which it is installed, due to <br />any reason including but not limited to controller failure, valve failure, broken heads, poor system design, <br />etc., the Contractor shall provide supplemental irrigation at no extra cost to the City. The Contractor may use <br />any reasonable means necessary to uniformly irrigate turf areas. Contractor may also submit AEW s with <br />engineered drawings to improve these areas of the system. <br />(6) Automatic irrigation shall be conducted between the hours of 10:00 p.m. and 4:00 a.m. and shall be <br />programmed not to exceed the EAW. In the event that Contractor's water consumption exceeds the EAW <br />City may deduct said overages from the Contractor's monthly invoice.
