The site is further located as a portion of Section 24, Township 27N, Range 3E, W.M. The parcel number for this property is 00434206702700. The purpose of this site visit was to locate and assess regulated critical areas on and adjacent to the subject site. Surrounding land use is comprised of forest land and single-family residential development. Access to this site is gained from the south via Main Street which runs along the southern border of the property. This undeveloped site is forested with a north aspect. Wetland A, a Category III wetland is located on the northern portion of the property and extends off -site to the north and east. Wetland A received 6 points for Habitat Functions on the DOE Wetland Rating Form for Western Washington: 2014 Update. This wetland is associated with Shell Creek which is located north of the subject site and drains to the northwest. Shell Creek is designated by the City of Edmonds as a known anadromous fish bearing stream (Type F stream which contains fish habitat). In the City of Edmonds, Category III wetlands with moderate habitat scores (6 to 7 points) receive a 110-foot buffer measured from the delineated edge. Type F streams typically receive 100-foot buffers measured horizontally in a landward direction from the delineated ordinary high water mark (OHWM). PROJECT DESCRIPTION The City of Edmonds acquired the subject property with the purpose of creating a park for the public benefit. As a part of this project, the City is proposing to install a park sign with a short pedestrian trail that leads to a wildlife viewing bench and an interpretive sign. The trail to access the wildlife viewing bench will be no more than five feet in width and will be constructed with a surface that does not interfere with substrate permeability; likely wood chips or pervious pavers. At its nearest point, the proposed trail will extend to within 44 feet of Wetland A (this is approximately forty percent of the standard buffer). Installation of the proposed public amenities will result in a total of 408 square feet of permanent buffer impacts. No trees will be impacted as a result of this work. The buffer proposed to be impacted contains scattered native shrubs with a high percentage of invasive English ivy. As designed, installation of this infrastructure is a permitted activity and is in compliance with ECDC 23.50.040(G)(5)(c)(i)&(ii). Acre Environmental Consulting, LLC R1: February 14, 2024 ECA Study and Mitigation Plan for Edmonds Parks - Main Street Page 2 Edmonds, WA In addition to the above infrastructure, the applicant is proposing to install approximately fifty linear feet of wooden two -rail fence along the western portion of the site. The intent of this fence is to ensure public safety by delineating the park boundary and keeping pedestrians out of the adjacent private driveway. This fence will also serve to discourage visitors from creating new trails through the wetland buffer and thereby damaging buffer vegetation. The proposed fence will be installed within the wetland buffer on the subject site. Vegetation in this area is represented by a canopy of red alder (Alnus rubra, Fac) and Douglas fir (Pseudotsuga menziesii, FacU) with English laurel (Prunus laurocerasus, Upl), vine maple (Acer circinatum, Fac), hazelnut (Corylus cornuta, FacU), Himalayan blackberry (Rubus armeniacus, Fac), English ivy (Hedera helix, Upl), and sword fern (Polystichum munitum, FacU), in the understory. No wetland impacts will occur due to the construction of this fence. Furthermore, this fence will be installed in a manner that avoids all impacts to existing, established trees. This fence will be installed by hand or with hand held tools and it is expected that any temporary impacts from trampled vegetation will be minimal and will naturally regrow within a short time period. Assuming a maximum of six, eight -inch diameter fence posts are installed, the installation of this fence is expected to permanently impact less than 12 square feet of buffer. As proposed, the construction of a two -rail fence in the proposed location will result in negligible impacts to the on -site wetland buffer. The proposed fence will not degrade the functions and functional performance of the wetland or Shell Creek and is therefore, a permitted activity and is in compliance with ECDC 23.50.040(A). As mitigation for the 420 (408 square feet + 12 square feet = 420 square feet) square feet of proposed buffer impacts, the applicant is offering to enhance 450 square feet of the on -site buffer. The buffer proposed to be enhanced currently contains a high percentage of invasive species. Buffer enhancement will consist of removing invasive species and planting native trees as described in the Buffer Enhancement section of this plan. While the Edmonds Code does not contain mitigation ratios for impacts to buffer, the generally accepted ratio for permanent buffer impacts is 1:1 (buffer impact to mitigation). The proposed mitigation measures are expected to at a minimum, maintain the level of functions and values provided by the subject site and ensure that no significant adverse environmental impacts and no net loss of ecological functions occur as a result of this project. Acre Environmental Consulting, LLC R1: February 14, 2024 ECA Study and Mitigation Plan for Edmonds Parks - Main Street Page 3 Edmonds, WA COMPLIANCE WITH ECDC 23.40.120 (MITIGATION SEQUENCING) Pursuant to ECDC 23.40.120, "Applicants shall demonstrate that all reasonable efforts have been examined with the intent to avoid and minimize impacts to critical areas. When an alteration to a critical area is proposed, such alteration shall be avoided, minimized, or compensated for in the following sequential order of preference": Note. the City requirements are in italics while the applicants responses are in plain text: 1. Avoiding the impact altogether by not taking a certain action or parts of an action; While the applicant has designed this project to avoid critical areas impacts to the greatest extent possible, given the requirements of this parks property and the constraints unique to this site, it is not feasible to entirely avoid impacts to the subject buffer. All impacts have been limited to those required to facilitate public use and accommodate the proposed interpretive sign and a short pedestrian trail to a wildlife viewing bench. 2. Minimizing impacts by limiting the degree or magnitude of the action and its implementation by using appropriate technology or by taking affirmative steps, such as project redesign, relocation, or timing, to avoid or reduce impacts; As discussed above, the applicant has designed this project to avoid critical areas impacts to the greatest extent possible. 3. Rectifying the impact to wetlands, frequently flooded areas, and fish and wildlife habitat conservation areas by repairing, rehabilitating, or restoring the affected environment to the historical conditions or the conditions existing at the time of the initiation of the project; As mitigation for the proposed buffer impacts, the applicant is offering to enhance 450 square feet of what is currently degraded buffer containing a high percentage of invasive species on the subject site. 4. Minimizing or eliminating the hazard by restoring or stabilizing the hazard area through engineering or other methods; The proposed wildlife viewing bench has been placed as far as is feasible from the subject wetland. The pedestrian access path will be limited to no more than five feet in width and will be constructed with a surface that does not interfere with substrate permeability; likely wood chips or pervious pavers. No trees will be impacted as a result of this work. As Acre Environmental Consulting, LLC R1: February 14, 2024 ECA Study and Mitigation Plan for Edmonds Parks - Main Street Page 4 Edmonds, WA designed, installation of this infrastructure is a permitted activity and is in compliance with ECDC 23.50.040(A) and ECDC 23.50.040(G)(5)(c)(i)&(ii). 5. Reducing or eliminating the impactor hazard overtime by preservation and maintenance operations during the life of the action; Following the proposed buffer impact, the applicant will permanently preserve and protect the subject wetland and buffer as a public park. Developing this site in the manner proposed will also provide a long term custodial presence that will ensure that the subject critical areas remain trash free and are not overrun by transients. 6. Compensating for the impact to wetlands, frequently flooded areas, and fish and wildlife habitat conservation areas by replacing, enhancing, or providing substitute resources or environments; and/or As discussed above, the applicant is proposing to provide buffer enhancement on the site. In addition, to increase public understanding and appreciation forthe critical areas on this site and in general, the applicant is proposing to install a park sign near the entrance to the trail and an interpretive sign near the wildlife viewing bench. 7. Monitoring the hazard or other required mitigation and taking remedial action when necessary. Following the successful installation of the proposed wetland and buffer enhancement, these aeras will be monitored for a period of five years to ensure the successful establishment of this mitigation as required by ECDC 23.40.130 (Mitigation Plan Requirements) Mitigation for individual actions may include a combination of the above measures. Acre Environmental Consulting, LLC R1: February 14, 2024 ECA Study and Mitigation Plan for Edmonds Parks - Main Street Page 5 Edmonds, WA METHODOLOGIES OF CRITICAL AREAS DETERMINATION On November 1, 2023 Acre Environmental Consulting, LLC conducted a site visit to locate wetlands and streams on and adjacent to the subject site. The methods used for delineating, classifying, and rating the critical areas in the project area are consistent with current Federal, State, and City of Edmonds requirements. At the time of our November 1, 2023 site investigation, the weather was cloudy with a temperature of 49 degrees Fahrenheit. Wetlands were identified using the routine methodologies described in the U.S. Army Corps of Engineers Wetland Delineation Manual produced in 1987 and the U.S. Army Corps of Engineers Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region produced in May 2010 (hereinafter referred to as "the Corps Regional Supplement"). The Corps Regional Supplement is designed for concurrent use with the 1987 Corps Wetland Delineation Manual and all subsequent versions. The 2010 Regional Supplement provides technical guidance and procedures for identifying and delineating wetlands that may be subject to regulatory jurisdiction under Section 404 of the Clean Water Act. Where differences in the two documents occur, the Corps Regional Supplement takes precedence over the Corps Manual for applications in the Western Mountains, Valleys, and Coast Region. According to the federal methodologies described above, identification of wetlands is based on a three -factor approach involving indicators of hydrophytic vegetation, hydric soils, and the presence or evidence of persistent hydrology. Except where noted in the manuals, the three - factor approach discussed above requires positive indicators of hydrophytic vegetation, hydric soils, and wetland hydrology, to make a determination that an area is a regulated wetland. Using the aforementioned manuals, the procedure for making a wetland determination include the following: 1.) Examination of the site for hydrophytic vegetation (species present/percent cover); 2.) Examination for the presence of hydric soils in areas where hydrophytic vegetation is present; and 3.) The final step is determining if wetland hydrology exists in the area examined under the first two steps. Per industry standards, Acre Environmental Consulting, LLC examined the entire project site. Per current City of Edmonds requirements, Acre Environmental Consulting, LLC also assessed adjacent properties within 300 feet of the proposed project limits, to the maximum extent possible without entering adjacent properties. While a detailed assessment of Environmentally Critical Areas on adjacent properties was not possible due to the lack of legal access, Acre Environmental Consulting, LLC conducted a review of all available information to assess the presence of off -site Critical Areas within 300 feet of the subject site. This review is required by the City of Edmonds to determine if any regulated Critical Areas exist off -site which would cause associated protective Acre Environmental Consulting, LLC R1: February 14, 2024 ECA Study and Mitigation Plan for Edmonds Parks - Main Street Page 6 Edmonds, WA buffers to extend onto the property and affect the development proposal. In addition to on -site field reviews, Acre Environmental Consulting, LLC examined aerial photographs and topographical data on Snohomish County's PDS Map Portal map system. Critical areas information on the Edmonds GIS Maps, Web soil survey maps produced by the Natural Resources Conservation Service (NRCS), National Wetlands Inventory (NWI) maps produced by the U.S. Fish and Wildlife Service (USFWS), SalmonScape fish distribution maps produced by the Washington Department of Fish and Wildlife (WDFW), and StreamNet fish distribution maps produced by Pacific States Marine Fisheries Commission. BOUNDARY DETERMINATION FINDINGS Wetlands and streams were classified according to the U.S. Fish and Wildlife Service (USFWS) Cowardin system Classification of Wetlands and Deepwater Habitats of the United States (Cowardin et al., 1979) and rated, by categories, according to the Washington State Department of Ecology Wetland Rating Form for Western Washington: 2014 Update, as required by the Edmonds City Code and Community Development Code, Chapter 23.50 (Wetlands). Buffers are also determined by this chapter. Wetland A HGM Class: Slope Cowardin: Palustrine, Forested wetland, Broad-leaved Deciduous, Seasonally Flooded/Saturated (PF01E) Department of Ecology Rating: Category III City of Edmonds Rating: Category III, 110' Buffer This hydrogeomorphic (HGM) class slope wetland is located on the northern portion of the property and extends off -site to the north, east, and west. This wetland is associated with Shell Creek which is located north of the subject site and drains to the northwest. Wetland A received a total score for functions of 16 points (5 points for Water Quality Functions, 5 points for Hydrologic Functions, and 6 points for Habitat Functions) on the DOE Wetland Rating Form for Western Washington: 2014 Update. Wetlands with scores between 16 and 19 points for all functions are classified as Category III wetlands per EMC 23.50.040(F). In the City of Edmonds, Category III wetlands with moderate habitat scores (6 to 7 points) receive a 110-foot buffer measured from the delineated edge. The 110-foot buffer presumes that all applicable measures described in ECDC 23.50.040(F)(f) are implemented. Acre Environmental Consulting, LLC R1: February 14, 2024 ECA Study and Mitigation Plan for Edmonds Parks - Main Street Page 7 Edmonds, WA Vegetation in the subject wetland is represented by a canopy of red alder (Alnus rubra, Fac) and western red cedar (Thuja plicata, Fac) with salmonberry (Rubus spectabilis, Fac), holly (Ilex aquifolium, FacU), English ivy (Hedera helix, Upl), skunk cabbage (Lysichiton americanus, Obl), and lady fern (Athyrium filix femina, Fac), common in the understory. Soils in the on -site portion of this wetland have a Munsell color of black (10YR 2/1) with redoximorphic features of dark gray (10YR 4/1), and a texture of silt loam, from 0 to 18 inches below the surface. Soils in this wetland were saturated to the surface during our November 11, 2023 site visit. Shell Creek - Type F Stream Cowardin: Riverine, Upper Perennial, Streambed, Cobble Gravel (R3SB3) Snohomish County Rating: Type F stream, 150' Buffer Shell Creek drains to the northwest roughly 34 feet north of the northeastern corner of the subject site, at its nearest point. This stream is designated by the City of Edmonds as a known anadromous fish bearing stream (Type F stream which contains fish habitat). The Salmonscape maps produced by WDFW show that this stream is utilized by candidate Coho salmon (Oncorhynchus kisutch), and unlisted coastal Cutthroat trout (Oncorhynchus clarki). In the City of Edmonds, Type F anadromous fish bearing streams adjacent to reaches with anadromous fish access typically receive 100-foot buffers measured horizontally in a landward direction from the delineated ordinary high water mark (OHWM). This 100-foot buffer extends onto the subject site to just south of Wetland A, but is superseded by the wetland buffer. Non — Wetland Vegetation in the non -wetland portions of the property is represented by a canopy of western hemlock (Tsuga heterophylla, FacU), western red cedar (Thuja plicata, Fac), and big leaf maple (Acer macrophyllum, FacU) with English laurel (Prunus laurocerasus, Upl), hazelnut (Corylus cornuta, FacU), English ivy (Hedera helix, Upl), and sword fern (Polystichum munitum, FacU), common in the understory. Typical soils in the non -wetland portion of the site have a Munsell color of dark brown (10 YR 3/3) with a texture of gravelly sandy loam from 0 to 18 inches below the surface. Soils were moist throughout the profile during our November 11, 2023 site visit. Acre Environmental Consulting, LLC R1: February 14, 2024 ECA Study and Mitigation Plan for Edmonds Parks - Main Street Page 8 Edmonds, WA NATURAL RESOURCE CONSERVATION SERVICE SOILS DESCRIPTION: The Natural Resources Conservation Service (NRCS) mapped the subject property as being underlain by Alderwood-Urban land complex, 8 to 15 percent slopes. The NRCS describes Alderwood-Urban land complex as about 60 percent Alderwood gravelly sandy loam and about 25 percent urban land. Included in this unit are small areas of McKenna and Norma soils and Terric Medisaprists in depressional areas and drainageways on plains. Also included are small areas of soils that are very shallow over a hardpan; small areas of Everett, Indianola, and Ragnar soils on terraces and outwash plains; and soils that have a stony and bouldery surface layer. Included areas make up about 15 percent of the total acreage. The Alderwood soil is moderately deep over a hardpan and is moderately well drained. It formed in glacial till. Typically the surface layer is very dark grayish brown gravelly sandy loam about 7 inches thick. The upper part of the subsoil is dark yellowish brown and dark brown very gravelly sandy loam about 23 inches thick. A weakly cemented hardpan is at a depth of about 35 inches. Permeability of this soil is moderately rapid above the hardpan and very slow through it. Available water capacity is low. HABITAT ASSESSMENT Per ECDC 23.90.020(C), "A habitat assessment is an investigation of the project area to evaluate the potential presence or absence of designated critical fish or wildlife species or habitat." Based on a review of the PHS on the Web maps and the Salmonscape maps prepared by the Washington Department of Fish and Wildlife (WDFW), Shell Creek is utilized by candidate Coho salmon (Oncorhynchus kisutch) and unlisted coastal Cutthroat trout (Oncorhynchus clarki). As such, these species have a primary association with habitat on or adjacent to the project area. No disruptions or changes to the existing high or low stream flows will occur as a result of this proposal. Through the avoidance of any in -water work, the minimally invasive nature of the project (installing a pervious trail and wildlife viewing bench within the wetland buffer), and the presence of established, native vegetation between the proposed work and Shell Creek, we do not anticipate that sediment or pollutants from the project site will enter surface waters. Therefore, we do not anticipate any water quality changes to surface waters surrounding the property. The proposed project will not block any habitat corridors for listed species. No large woody debris will be impacted and no trees will be removed as a part of this project. While a small area (450 square feet) of wetland buffer dominated by scrub -shrub and emergent vegetation will be impacted, the applicant is proposing to offset this impact using buffer enhancement and the installation of an interpretive sign. The proposed project will have no impact on any natural channel migration areas and bank stability will not be impacted in any way because the project is approximately 103 feet away from the nearest stream bank. No modifications will occur to any Acre Environmental Consulting, LLC R1: February 14, 2024 ECA Study and Mitigation Plan for Edmonds Parks - Main Street Page 9 Edmonds, WA water body within the project area and no removal or changes in large woody debris (LWD) will occur. As a result, the proposed project will not result in any direct effects to fish species. Equipment used during the implementation of this project will produce temporarily elevated noise levels above the existing background sound levels. However, no terrestrial Wildlife Habitat Conservation Areas (nests) of listed avian species are located within the project area and no listed terrestrial species are mapped as occurring within the project area. Coho salmon do occur in the project area. However, because they are accustomed to the noisy, high energy environment of streams, the relatively low -intensity terrestrial noise generated by the project action when fish may be in the project area is not expected to have any harmful effects. Increases of sediment inputs to streams, particularly sediments that are 0.85 mm and smaller have been well documented to have a negative impact on fish and other aquatic life. However, due to the proposed implementation of applicable BMP erosion control measures and the distance of the work area from Shell Creek (approximately 103 feet at the nearest point), any sediment resultant from this project will not reach fish bearing waters. Although work for this project is proposed within the buffer of the subject wetland and stream, the distance of approximately 103 feet from the work area to Shell Creek (at the nearest point) and the lack of an above -ground surface connection alleviate the potential for negative impacts associated with the proposed project. This project will not result in any direct or indirect impacts to any species, and will generally maintain the existing condition of the site and the adjacent areas. Therefore, no impacts to designated critical fish or wildlife species or habitat are expected to occur. ECDC 23.40.280 (BUILDING SETBACKS) Except for geologically hazardous areas where setbacks are determined by a geotechnical report, buildings and other structures shall be set back a distance of 15 feet from the edges of all critical area buffers or from the edges of all critical areas, if no buffers are required. In addition to other allowances provided by this title, the following may be allowed in the building setback area: A. Landscaping; B. Uncovered decks; C. Building overhangs, if such overhangs do not extend more than 30 inches into the setback area; and D. Impervious ground surfaces, such as driveways and patios; provided, that such improvements may be subject to water quality regulations as adopted in the current editions of the International Residential Code and International Building Code, as adopted in ECDC Title 19. Acre Environmental Consulting, LLC R1: February 14, 2024 ECA Study and Mitigation Plan for Edmonds Parks - Main Street Page 10 Edmonds, WA EXISTING FUNCTIONS AND VALUES The methodologies for this functions and values assessment are based on professional opinion developed through past field analyses and interpretation. This assessment pertains specifically to the on -site streams, wetlands, and associated buffer, but is typical for assessments of similar systems common to western Washington. The three main functions provided by wetlands include water quality, stormwater / hydrologic control, and wildlife habitat. Buffers serve to protect and support the functions of wetlands and streams as well as provide their own wildlife habitat, water quality, and erosion control functions. Overall, the subject wetland and associated buffers provide a moderate level of functions and values. Wetland A is a hydrogeomorphic class slope wetland and as such, has a limited ability to retain stormwater. Due to the sloped nature of this system, rather than being stored in this wetland, water is released relatively quickly to downstream systems. Therefore, this wetland provides limited stormwater storage functions. Wetlands in western Washington often contain necessary wildlife habitat resources such as food, water, thermal cover, and hiding cover in close proximity. The subject wetland and associated buffer provide protected habitat, which becomes increasingly important as areas become further populated with humans and habitat areas become fragmented. The subject wetland provides a moderate level of habitat for wildlife species as evidenced by Habitat Function scores on the Wetland Rating Form for Western Washington: 2014 Update of 6. Habitat functions in this wetland are limited by the prevalence of invasive species in the wetland and associated buffer, its urban location, and proximity to roads and residential development. Even so, the subject wetland and stream corridor provide an area of protected habitat that is utilized by a variety of species. During our site visit a black -capped chickadee (Poecile atricapillus) and a bushtit (Psaltriparus minimus) were noted in the subject wetland and buffer. The dense vegetation within the wetland and associated buffers on this site serves to intercept rain fall before it strikes the soil, thereby reducing erosion and improving water quality. The presence of adsorbent soils and the biological action of the wetland vegetation, serve to remove sediment and pollutants from the water. These materials are bound in the soil and plant material providing increased water quality to downstream systems. Shell Creek located north of the subject site provides important functions to the surrounding environment such as hydrological transport, transport of solids (suspended and dissolved), and important fish and wildlife habitat features, among other functions. The portions of the site adjacent to the stream (vegetated wetland and associated buffers, etc.) are increasingly important to manage appropriately as these areas aid in water quality and hydrologic control, resulting in cleaner water entering the stream's channel. Acre Environmental Consulting, LLC R1: February 14, 2024 ECA Study and Mitigation Plan for Edmonds Parks - Main Street Page 11 Edmonds, WA BUFFER ENHANCEMENT As mitigation for the 450 square feet of permanent buffer impacts resultant from the proposed trial and wildlife viewing bench, the applicant is offering to enhance 450 square feet of buffer on the site. Buffer enhancement will consist of removing invasive species and planting native trees and shrubs throughout the enhancement areas. All proposed species are native to the Puget Sound region and have been selected for their benefits to wildlife and their proven success on past mitigation projects. The following native trees and shrubs will be installed within the wetland and buffer enhancement areas. Buffer Enhancement Area — 450 square feet Common Name Latin Name Size Spacing Quantity Western red cedar Thuja plicata 1 gallon 10, 3 Pacific willow Salix lasiandra 1 gallon 5' 8 GRASS SEEDING Any disturbed soil in critical areas or buffers shall be seeded to the recommended grass seed mixtures below, or similar approved mixtures. Common Name Latin Name Ibs/1,000 sf Tall fescue Festuca arundinacea 0.4 Colonial bentgrass Agrostis tenuis 0.4 Annual ryegrass Lolium multiflorum 0.5 Red clover Trifolium pratense 0.2 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. Acre Environmental Consulting, LLC R1: February 14, 2024 ECA Study and Mitigation Plan for Edmonds Parks - Main Street Page 12 Edmonds, WA 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. PROJECT SUCCESS AND COMPLIANCE Goals and Objectives of the Proposed Mitigation: The primary goals of the proposed mitigation are as follow: • Increase the water quality and habitat functions within the on -site buffer; • Increase vegetative structure within the on -site buffer; • Increase the quantity and diversity of native vegetation within the on -site buffer; and • Allow for responsible development and associated infrastructure, while increasing the ecological functions provided by the subject site. Definition of Success: The planting areas shall meet the following performance standards: a) Year 1: 100 percent survival of newly planted species, b) Year 3: at least 80 percent survival of installed plant species, c) Year 5: at least 80 percent survival of installed plant species, This mitigation plan shall support at least 80% of the native plants set forth in the approved mitigation plan by the end of five years. The species mix should resemble that proposed in the planting plans, but strict adherence to obtaining all of the species shall not be a criterion for Acre Environmental Consulting, LLC R1: February 14, 2024 ECA Study and Mitigation Plan for Edmonds Parks - Main Street Page 13 Edmonds, WA Performance Standards: Performance Standard 1: There shall be 100 percent survival of all the plantings after Year 1 or the installation contractor shall replace the material. At least 80 percent of the plant material installed shall survive in Year 5 after installation. Performance Standard 2: There shall be a minimum of 30 percent cover of woody species (shrub and tree canopy layers considered together) in the buffer after the first year post -installation; and a minimum of 50 percent cover by woody material after the third year post -installation; and a minimum of 80 percent cover by woody material after the fifth year post -installation. Naturally occurring, native plants shall be included in the calculation of vegetation coverage. Performance Standard 3: There shall be no more than 20 percent cover of weedy/invasive species in the mitigation areas at any time throughout the monitoring period. If the project meets all of the criteria for success at the end of the five-year monitoring period, no further action will be required and the financial guarantee will be returned to the applicant in full. If the definition of success is not met for any reason at the end of the five-year monitoring period, the maintenance and monitoring period will be extended for one year at a time until the site meets the stated performance standards. If the definitions of success and the accompanying performance standards are met in less than five years, the monitoring may be terminated and the bond released at that point. This mitigation plan and the accompanying maintenance and monitoring will not be considered fully complete until written confirmation is received from the City of Edmonds. PROJECT MONITORING PROGRAM Requirements for monitoring project: 1. Initial compliance report 2. Annual site inspection (in the fall) for five years 3. Annual reports (One report submitted in the fall of each monitored year) Purpose of Monitoring: The purpose of monitoring this mitigation project is to evaluate the success of the mitigation plantings. Success will be determined if monitoring shows that at the end of five years the stated performance standards are being met. The property owner shall grant access to the site for inspection and maintenance to the contracted wetland specialist and to the City of Edmonds during the period of the bond or until the project is evaluated as successful. Acre Environmental Consulting, LLC R1: February 14, 2024 ECA Study and Mitigation Plan for Edmonds Parks - Main Street Page 14 Edmonds, WA Inspection Schedule: Upon completion of the mitigation project, an inspection by a qualified wetland biologist will be made to determine plan compliance. An "As Built" report will be supplied to the City of Edmonds regarding the completeness of the project. Condition monitoring of the plantings will be done by a qualified wetland biologist in the fall annually for the five-year monitoring period. A written report describing the monitoring results will be submitted to the City of Edmonds shortly after the inspection of each monitored year. Final inspection will occur five years after completion of planting. The contracted wetland professional will prepare a final report as to the success of the project. MAINTENANCE The mitigation areas will require periodic maintenance to remove undesirable species and replace plant mortality. The planting areas should be maintained in spring and fall of each year for the five-year monitoring period. Maintenance may include, but will not be limited to, removal of competing grasses and invasive species (by hand if necessary), irrigation, replacement of plant mortality, and the replacement of mulch for each maintenance period. Following each monitoring visit, the project biologist will make recommendations for maintenance. CONTINGENCY PLAN If 20% of the plants are severely stressed during any of the inspections, or it appears 20% may not survive, additional plantings of the same species may be added to the planting area. Elements of a contingency plan may include, but will not be limited to: more aggressive weed control, pest control, mulching, replanting with larger plant material, species substitution, fertilization, soil amendments, and/or irrigation. Acre Environmental Consulting, LLC R1: February 14, 2024 ECA Study and Mitigation Plan for Edmonds Parks - Main Street Page 15 Edmonds, WA FINANCIAL GUARANTEE A mitigation bond or other security shall be provided to the City of Edmonds in a form and amount deemed acceptable by the City to ensure mitigation is fully functional. The bond shall be in the amount of 120 percent of the estimated cost of the uncompleted actions or the estimated cost of restoring the functions and values of the critical area at risk, whichever is greater. The amount of the performance bond shall include a reasonable allocation for inflation based on the length of anticipated delay. Annual monitoring reports and seasonal maintenance will be required to assure the success of this mitigation plan. Bonds or other security devices shall remain in effect until the director determines, in writing, that the standards bonded for have been met. Bonds or other security shall be held by the City for a minimum of five years to ensure that the required mitigation had been fully implemented and demonstrated to function, and may be held for longer periods when necessary. The following is an estimate of plant materials and labor only. This does not represent a bid to install: QUANTITY OF ONE GALLON PLANTS @ $10.50 PER PLANT 11 ESTIMATED COST OF PLANT MATERIAL AND LABOR $115.50 ESTIMATED COST OF GRASS SEED $15.00 TOTAL ESTIMATED COSTS $130.50 TOTAL BOND AMOUNT (120% OF TOTAL ESTIMATED COSTS) $156.50 POST -PROJECT FUNCTIONS AND VALUES Although impacts within the on -site buffer are necessary to accommodate the proposed park project, no net loss of ecological functions is expected to occur. Through careful site design, buffer impacts have been minimized to the greatest extent practical. In addition to providing a future source of source of shade and large woody debris for Shell Creek, the proposed buffer enhancement will remove invasive species and increase vegetative species diversity and vegetative structure within the subject wetland buffer. This will increase wildlife habitat as well as water quality and stormwater storage functions, and is expected to generally increase the overall level of functions and values provided by the subject site. The proposed mitigation measures are expected to at a minimum, maintain the level of functions and values provided by the subject site and ensure that no significant adverse environmental impacts and no net loss of ecological functions occur as a result of this project.
