Water Plants shall be watered midway through backfilling, and again upon completion of backfilling. For spring plantings (if approved), a rim of earth shall be mounded around the base of the tree or shrub no closer than the drip line, or no less than 30" in diameter, except on steep slopes or in hollows. Plants shall be watered a second time within 24-48 hours after installation. The earthen rim / dam should be leveled prior to the second growing season. Staking Most shrubs and many trees DO NOT require any staking. If the plant can stand without staking in a moderate wind, do not use a stake. If the plant needs support, then strapping or webbing should be used as low as possible on the trunk to loosely brace the tree with two stakes. Do not brace the tree tightly or too high on the trunk. If the tree is unable to sway, it will further lose the ability to support itself. Do not use wire in a rubber hose for strapping as it exerts too much pressure on the bark. As soon as supporting the plant becomes unnecessary, remove the stakes. All stakes must be removed within two (2) years of installation. Plant Location Colored surveyors ribbon or other appropriate marking shall be attached to the installed plants to assist in locating the plants while removing any competing non-native vegetation and to assist in locating the plants during the monitoring period. Arrangement and Spacing The plants shall be arranged in a pattern with the appropriate numbers, sizes, species, and distribution that are required in accordance with the approved plans. The actual placement of individual plants shall mimic natural, asymmetric vegetation patterns found on similar undisturbed sites in the area. Mulch After plant installation, mulch rings shall be installed around each new planting. No less than 3 inches of woodchip (arborist) mulch shall be applied in a 2-foot diameter ring around each installed plant. Woodchips shall be kept at least 2 inches from the trunks or stems of plants to prevent plant damage. 13.0 MAINTENANCE The mitigation areas will require periodic maintenance to ensure success of the mitigation measures. Maintenance shall occur in accordance with the approved plans. Maintenance may include, but will not be limited to: removal of competing grasses (by hand if necessary), irrigation, fertilization (if necessary), replacement of plant mortality, and the replacement of mulch as needed. Chemical control, only if approved by County staff, shall be applied by a licensed applicator following all label instructions.
