root ball must be roughened from top to bottom to a depth of approximately half an inch in two <br />to four places. <br />Sizes <br />Plant sizes shall be the size indicated in the plant schedule in approved plans. Larger stock may <br />be acceptable provided that it has not been cut back to the size specified, and that the root ball is <br />proportionate to the size of the plant. Smaller stock may be acceptable, and preferable under <br />some circumstances, based on site -specific conditions. Measurements, caliper, branching, and <br />balling and burlapping shall conform to the American Standard of Nursery Stock by the <br />American Association of Nurserymen (latest edition). <br />Form <br />Evergreen trees shall have single trunks and symmetrical, well -developed form. Deciduous trees <br />shall be single trunked unless specified as multi -stem in the plant schedule. Shrubs shall have <br />multiple stems and be well -branched. <br />Timing of Planting <br />Unless otherwise approved by City staff, all planting shall occur between November 1 and March <br />1. Overall, the earlier plants go into the ground during the dormant period, the more time they <br />have to adapt to the site and extend their root systems before the water demands of spring and <br />summer. <br />Weeding <br />Existing and exotic vegetation in the mitigation areas will be hand -weeded from around all newly <br />installed plants at the time of installation and on a routine basis throughout the monitoring <br />period. <br />Site conditions <br />The contractor shall immediately notify the landscape designer and/or wetland biologist of <br />drainage or soil conditions likely to be detrimental to the growth or survival of plants. Planting <br />operations shall not be conducted under the following conditions: freezing weather, when the <br />ground is frozen, excessively wet weather, excessively windy weather, or in excessive heat. <br />Planting Pits <br />Planting pits shall be circular or square with vertical sides, and shall be 6" deeper and 12" larger <br />in diameter than the root ball of the plant. Break up the sides of the pit in compacted soils. Set <br />plants upright in pits. Burlap shall be removed from the planting pit. Backfill shall be worked <br />back into holes such that air pockets are removed without compacting soils. <br />Fertilizer <br />Slow release fertilizer may be used if pre -approved by Snohomish County. Fertilizers shall be <br />applied only at the base of plantings underneath the required covering of mulch (that does not <br />contact stems of the plants). No soil amendment or fertilizers will be placed in planting holes. <br />APV Ventures LLC — Dakota Way 17 Critical Area Repor4 Buffer Mitigation <br />WRI #20015 Plan &RabitatAssesswnt <br />April27, 2020 <br />
