Monitor tree support systems(stakes,guys, etc.). O Repair and adjust as needed to provide support and prevent tree damage. • Remove tree supports after one growing season or maximum of 1 year. • Backfill stake holes after removal. . When continued, regular pruning (more than one time during the growing season) is required to maintain visual sight lines for safety or clearance along a walk or drive, consider relocating the plant to a more appropriate location. . Make reasonable attempts to remove and dispose of class C noxious weeds. . Re-seed bare turf areas until the vegetation fully covers the ground surface. . Watch for and respond to new occurrences of especially aggressive weeds such as Him- alayan blackberry, Japanese knotweed, morning glory, English ivy, and reed canary grass to avoid invasions. . Plant and protect trees per BMP T5.16: Tree Retention and Tree Planting. . Aerate lawns regularly in areas of heavy use where the soil tends to become compacted. Con- duct aeration while the grasses in the lawn are growing most vigorously. Remove layers of thatch greater than 3h-inch deep. . Set the mowing height at the highest acceptable level and mow at times and intervals designed to minimize stress on the turf. Generally mowing only 1/3 of the grass blade height will prevent stressing the turf. • Mowing is a stress-creating activity for turfgrass. o Grass decreases its productivity when mowed too short and there is less growth of roots and rhizomes. The turf becomes less tolerant of environmental stresses, more dis- ease prone and more reliant on outside means such as pesticides,fertilizers, and irrig- ation to remain healthy. Additional BMP Information: . King County's Best Management Practices for Golf Course Development and Operation (King County, 1993) has additional BMPs for Turfgrass Maintenance and Operation. . King County, Seattle Public Utilities, and the Saving Water Partnership have created the fol- lowing natural lawn and garden care resources that include guidance on building healthy soil with compost and mulch, selecting appropriate plants,watering, using alternatives to pesti- cides, and implementing natural lawn care techniques. 2019 Stormwater Management Manual for Western Washington Volume IV-Chapter 4-Page 526
