PLANTING NOTES Wetland and buffer mitigation projects are typically more complex to install than can be described in plans. Careful monitoring by a professional wetland scientist for all portions of this project is strongly recommended.Timing and sequencing is important to the success of this type of project. Plant in the early spring or late fall. Order plants from a reputable nursery. Care and handling of plant materials is extremely important to the overall success of the project. All plant materials recommended in this plan should be available from local and regional sources, depending on seasonal demand. Some limited species substitution may be allowed, only with the agreement of the consulting wetland professional. The plants shall be arranged with the appropriate numbers, sizes, species, and distribution to achieve the required vegetation coverage. The actual placement of individual plants shall mimic natural, asymmetric vegetation patterns found on similar undisturbed sites in the area. Colored surveyors ribbon, or other approved marking device shall be placed next to each planted tree and shrub to assist in locating the plants while removing the competing non-native vegetation and to assist in monitoring the plantings. Wood chips or other suitable material shall be used for mulching in the planting areas. Any existing vegetation is to be removed from a two-foot diameter area at each planting site. Mulch is to be placed in this two-foot diameter area at a depth of three to four inches. A four-inch diameter ring around the base of each plant shall be kept free of mulch. Water should be provided during the dry season (July 1 through October 15) for the first two years after installation to insure plant survival and establishment. A temporary above ground irrigation system and/or water truck should provide water. Water should be applied at a rate of 1 inch of water twice per week for year one and 1 inch per week during year two. Appropriate BMP erosion control measures shall be installed and functioning prior to commencement of the mitigation measures. PROJECT SUCCESS AND COMPLIANCE Goals and Objectives of the Proposed Mitigation:The primary goals of the proposed mitigation are as follow: • Increase/ restore the water quality and habitat functions within the subject buffer; • Increase/ restore vegetative structure within the on-site wetland and stream buffer; Acre Environmental Consulting, LLC November 22, 2021 Buffer Mitigation Plan for 2924 100th Street SE Page 4 Everett, WA
