APPENDIX B <br />IGA 2008-01033 <br />City/District 4-J Park Maintenance Standards <br />MODE II-YSP <br />March 24, 2008 <br />The following standards are based on the park maintenance standards published by the <br />National Recreation and Park Association (NRPA), Mode II: High level maintenance - <br />associated with well developed park areas with reasonably high visitation. As allowed for by the <br />NRPA's standards, some adjustments have been made to better fit local conditions and <br />situations. The Mode II-YSP standards, below, will apply only to the identified Youth Sports <br />Parks. <br />Turf Care - Youth sports parks will contain two types of turf areas: sports turf, defined as the <br />grass playing surface of designated sports fields, and park turf, irrigated turfgrass <br />outside the boundaries of sports fields. These two types of areas will be <br />maintained to different standards: <br />Sports turf - Mowed a minimum of and once every five working days. Aeration as required, <br />but not less than two times per year. Over-seeding practiced to maintain turf <br />stand and vigor, based on sport and level of play. Re-seeding or sodding when <br />bare spots appear. Top-dressing as required to maintain adequate playing <br />surface. Weed control and/or spot renovation practiced when weed present <br />visible problem, interfere with play, or when weeds represent 5% of the sports <br />turf surface of any field(s), as a goal, but no more than 10% in any case. <br />Park Turf - Mowed once every five working days. Aeration as required, typically to relieve <br />visible turf stress due to soil compaction. Over-seeding may be practices to re- <br />invigorate weak or thin turf stands. Re-seeding or sodding when bare spots <br />appear. Weed control and/or spot renovation practiced when 50% of identifiable <br />small area is weed infested or when weeds represent 25% of park turf surface. <br />Fertilizer - Adequate fertilizer level to insure that all park turf and landscape plant materials <br />are healthy and growing vigorously. Amounts depend on species, length of <br />growing season, soils, and rainfall. Rates should correspond to the <br />recommendations or the Oregon State university Department of Horticulture <br />and/or the County Extension Service, or an equivalent recognized authority. <br />Sports turf - In addition to the above, sports turf may require/receive additional or <br />supplemental fertilizer application or soil amendments due to high user traffic or <br />the sports/season played and resultant need to keep grass vigorously growing <br />earlier or later than normal for park turf, above. Rates should correspond to the <br />recommendations of the Oregon State University Department of Horticulture <br />and/or the County Extension Service, or an equivalent recognized authority. <br />Irrigation All sports turf, park turf, and landscape planting within the Youth Sports Parks will <br />be irrigated by an automatic irrigation system connected to a centralized, <br />automated control system linked to a weather station that automatically adjusts <br />irrigation rates based on local weather and evapo-traspiration rates. <br />Intergovernmental Agreement 2008-01033: Joint Use And Development of Artificial Turf Athletic Fields - Appendix 8 <br />Page 1 of 7 July 1, 2008 <br />
