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 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 back <br /> into holes such that air pockets are removed without compacting soils. <br /> Staking <br /> Most shrubs and many trees DO NOT require any staking. If the plant can stand without staking <br /> in a moderate wind, do not use a stake. If the plant needs support, then strapping or webbing <br /> should be used as low as possible on the trunk to loosely brace the tree with two stakes. Do not <br /> brace the tree tightly or too high on the trunk. If the tree is unable to sway, it will further lose the <br /> ability to support itself.Do not use wire in a rubber hose for strapping as it exerts too much pressure <br /> on the bark. As soon as supporting the plant becomes unnecessary, remove the stakes. All stakes <br /> must be removed within two (2)years of installation. <br /> Plant Location <br /> Colored surveyors ribbon or other appropriate marking shall be attached to the installed plants to <br /> assist in locating the plants while removing any competing non-native vegetation and to assist in <br /> locating the plants during the monitoring period. <br /> Arrangement and Spacing <br /> The plants shall be arranged in a pattern with the appropriate numbers, sizes, species, and <br /> distribution that are required in accordance with the approved plans. The actual placement of <br /> individual plants shall mimic natural, asymmetric vegetation patterns found on similar undisturbed <br /> sites in the area. <br /> 2127100th Street SE 16 WRI#23188 <br /> Critical Area Study and Mitigation Plan October 9, 2023 <br />
