Sedges and rushes shall be plugs and will be planted on 18" centers in several lazge <br />clumps covering 10 percent of the area. <br />PLANTING AREA DETAILS <br />The plantings will be arranged in a pattern of appropriate numbers, sizes, species and <br />distribution of plants to achieve the desired vegetation coverage. The actual placement of <br />individual plants shall attempt to mimic namr�l, asymmetric vegetation patterns found on <br />similar undismrbed sites in the area. Plant spacing may be adjusted so that existing <br />native vegetation remains undisturbed. An on site pre-planting meeting involving the <br />consulting biologist and the landscape contractor shall occur. The areas for planting will <br />be staked at that time. Planting areas will be determined by soil conditions, hydrology, <br />and exisung vegetation. <br />PLAYTING NOTES <br />. Plant in the earl�,��s ring,or late fall. Order plants from a reputable nursery. Care and <br />handling of plan[ materials is extremely importmit to the overall success of the <br />project. <br />• Com�tition from non native erasses 5cot's broom blackbenies, and Jananese <br />knotweed will tend to overgrow the planted species. Maintenance will be necessary <br />a minimum of twice a year for the first and second growing seasons following <br />construction. Grasses should be cut away from the planted nacive species. <br />. Two foot tall lath stakes should be driven to a depth of at least six inches next to <br />each shrub planted to assist in locatin; the plants while removing the competing <br />undesirable vegetation. <br />• Chemicals mav be used to eliminate undesirable plant species if determined <br />necessary by a Snohomish County Biologist and Consulting Biologist. <br />. Suanle^.T mental irrieation may be necessary for the first and second summer, at least <br />once per week, during periods of drou;ht. This wi115e determined by a Snohomish <br />Counry Biologist and Consulting Biologist. <br />• Noxious weed control <br />The State of Washington has established a weed control law (RCW 17.10) in which <br />ceRain "designate" species of weeds are to be controlled by landowners. Other "non- <br />designate" species may be abundant in certain regions and control of the species is a <br />local option. Control is defined in WAC 16-750 as the prevention of all seed <br />production. The Snohomish County Noxious Weed Control Board has established a <br />loc:il list of species designated for control. <br />1 z W� <br />
