(WRI) conducted site investigations on October 18, 2019 to locate wetlands and streams on and in the vicinity of the investigation area, which is composed of King County tax parcel 3343300861. The site is approximately 1.9-acres, located west of the intersection of Lake Washington Boulevard NE and Southeast 73rd Street in the City of Renton, Washington (Section 29, Township 24N, Range 5E, W.M. The body of this report presents findings regarding the wetlands and streams on-site. 1.1 SITE DESCRIPTION The investigation area is located within the May Creek sub-basin of the Cedar River/Lake Washington Watershed (WRIA 8). Lake Washington is approximately 600 feet west of the subject property. Surrounding land use is generally residential and undeveloped land with Interstate 405 border the site along its western boundary. The site is undeveloped and vegetation is mostly dominated by native species with areas of Himalayan blackberry in the understory. Topography is generally a moderate to steep west aspect - Aerial view of the subject parcel. DocuSign Envelope ID: C2073BA0-CA13-4596-8BE6-FB745ABA8D08 Critical Area Study & Conceptual Buffer Enhancement Plan Wetland Resources, Inc. #19300 Blue Fern Development – Off-site Benefit Parcel 2 November 21, 2019 Three wetlands (Wetlands A through C) and two stream (Streams A and B) were identified within the investigation area. Pursuant to Renton Municipal Code (RMC), on-site wetlands were classified under the Washington State Wetland Rating System for Western Washington: 2014 Update (Hruby 2014). Wetland A is classified as Category IV wetland. Wetlands B and C are classified as Category III wetlands with moderate habitat scores (5 habitat points). Per RMC (7)(a) the onsite streams were classified based on the WAC 222-16-030. As such, Stream A is classified as a Type F Stream and Stream B is classified as a Type Ns. Per 4-3-050(G)(2), Category IV wetlands typically receive 50-foot buffers, Category III wetlands typically receive 100-foot buffers (when adjacent to non-low impact land uses), Type F streams typically receive 115-foot buffer and Type Np streams typically receive 75-foot buffers. 1.2 PROJECT DESCRIPTION The applicant is proposing to purchase this property for the purpose of conservation. The intent is to acquire, enhance and permanently protect this property for the public benefit. 2.0 CRITICAL AREAS DETERMINATION REPORT 2.1 PUBLICLY AVAILABLE DATA Prior to conducting the site investigation, public resource information was reviewed to gather background information on the subject parcels and the surrounding area in regards to wetlands, streams, and other critical areas. These sources included the following: • USDA/NRCS Web Soil Survey shows 2 soil units underlying the subject property: Alderwood gravelly sandy loam (8-15 percent slopes) and Kitsap silt loam (8-15 percent slopes). • WDFW SalmonScape Interactive Mapping System depicts a stream on the subject property, but does not identify it as fish bearing. • USFWS National Wetlands Inventory (NWI) does not show any wetlands on the subject property, however it does map a stream. • WDFW Priority Habitat and Species (PHS) Interactive Map does not show any priority species or habitats on the subject parcel or in the near vicinity. • King County iMap shows an unclassified stream within the boundary of the subject property. • City of Renton Maps of Your Community (CRM) shows a stream flowing across the property. DocuSign Envelope ID: C2073BA0-CA13-4596-8BE6-FB745ABA8D08 Critical Area Study & Conceptual Buffer Enhancement Plan Wetland Resources, Inc. #19300 Blue Fern Development – Off-site Benefit Parcel 3 November 21, 2019 2.2 WETLAND & STREAM DETERMINATION METHODOLOGY The OHWM of streams in the investigation area were identified using the methodologies described in the Washington State Department of Ecology (DOE), Determining the Ordinary High Water Mark for Shoreline Management Act Compliance in Washington State (Anderson et al. 2016). The Washington State Shoreline Management Act (SMA) defines ordinary high water mark as, “…that mark that will be found by examining the bed and banks and ascertaining where the presence and action of waters are so common and usual, and so long continued in all ordinary years, as to mark upon the soil a character distinct from that of the abutting upland, in respect to vegetation as that condition exists on June 1, 1971, as it may naturally change thereafter, or as it may change thereafter in accordance with permits issued by a local government or the department: PROVIDED, that in any area where the ordinary high water mark cannot be found, the ordinary high water mark adjoining salt water shall be the line of mean higher high tide and the ordinary high water mark adjoining fresh water shall be the line of mean high water.” Wetland boundaries were determined using the routine approach described in the Corps of Engineers Wetlands Delineation Manual (Environmental Laboratory 1987) and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region (Version 2.0) (U.S. Army Corps of Engineers 2010). Under the routine methodology, the process for making a wetland determination is based on three steps: 1) Examination of the site for hydrophytic vegetation (species present and percent cover); 2) Examination of the site for hydric soils; 3) Determining the presence of wetland hydrology The following criteria must be met in order to make a positive wetland determination: 2.2.1 Hydrophytic Vegetation Criteria The Corps Manual and 2010 Regional Supplement define hydrophytic vegetation as “the assemblage of macrophytes that occurs in areas where inundation or soil saturation is either permanent or of sufficient frequency and duration to influence plant occurrence.” Field indicators are used to determine whether the hydrophytic vegetation criteria have been met. Examples of these indicators include, but are not limited to, the rapid test for hydrophytic vegetation, a dominance test result of greater than 50%, and/or a prevalence index score less than or equal to 3.0. 2.2.2 Soils Criteria and Mapped Description The 2010 Regional Supplement (per the National Technical Committee for Hydric Soils) defines hydric soils as soils “that formed under conditions of saturation, flooding, or ponding long enough during the growing season to develop anaerobic conditions in the upper part.” Field indicators are used to determine whether a given soil meets the definition for hydric soils. Indicators are numerous and include, but are not limited to, presence of a histosol or histic epipedon, a sandy gleyed matrix, depleted matrix, and redoximorphic depressions. DocuSign Envelope ID: C2073BA0-CA13-4596-8BE6-FB745ABA8D08 Critical Area Study & Conceptual Buffer Enhancement Plan Wetland Resources, Inc. #19300 Blue Fern Development – Off-site Benefit Parcel 4 November 21, 2019 According to the NRCS Web Soil Survey, two soil map units are predicted to occur on the subject property: Ragnar-Indianola association (moderately steep, sloping) and Alderwood gravelly sandy loam (8-15, 15-30 percent slopes). Alderwood Gravelly Sandy Loam (8-15 percent slopes,), is described as a moderately well drained soil on till plains. It is moderately deep over a hardpan. This soil 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. Included in this unit are small areas of soils that have a stony or bouldery surface layer and areas of McKenna soils, Norma soils, and Terric Medisaprists in drainageways on plains. Also included are small areas of Everett, Indianola, and Ragnar soils on terraces and outwash plains. Included areas make up about 15 percent of the total acreage. Permeability of this soil is moderately rapid above the hardpan and very slow through it. Available water capacity is low. Kitsap Silt Loam (8-15 percent slopes) is made up of moderately well drained soils that formed in glacial lake deposits, under a cover of conifers and shrubs. These soils are on terraces and strongly dissected terrace fronts. They are generally undulating and rolling and moderately steep. Platy, silty sediments are at a depth of 18 to 40 inches. In a representative profile, the surface layer and subsoil are very dark brown and dark yellowish brown silt loam that extends to a depth of about 24 inches. The subsoil is olive-gray silty clay loam. It extends to a depth of 60 inches or more. Soils included with this soil in mapping make up no more than 30 percent of the total acreage. Some areas are up to 15 percent Alderwood gravelly sandy loam; some are up to 15 percent the very deep, sandy Indianola soils; and some are up to 2 percent the poorly drained Bellingham, Seattle, and Tukwila soils. Runoff is rapid, and the erosion hazard is severe. Slippage potential is severe. Permeability is moderate above the substratum and very slow within it. Available water capacity is moderate to moderately high. 2.2.3 Hydrology Criteria The 2010 Regional Supplement defines wetland hydrology as “areas that are inundated (flooded or ponded) or the water table is less than or equal to 12 inches below the soil surface for 14 or more consecutive days during the growing season at a minimum frequency of 5 years in 10.” During the early growing season, wetland hydrology determinations are made based on physical observation of surface water, a high water table, or saturation in the upper 12 inches. Outside of the early growing season, wetland hydrology determinations are made based on physical evidence of recent inundation or saturation (i.e. water marks, surface soil cracks, water-stained leaves). 2.3 WETLAND & STREAM BOUNDARY DETERMINATION FINDINGS 2.3.1 Wetland A Cowardin Classification: Palustrine, Forested, Broad-leaved Deciduous, Saturated Only. City of Renton Classification: Category IV (low wildlife function) City of Renton Buffer: 50-feet Wetland A is a slope wetland located in the southern portion of the investigation area, Dominant vegetation within the wetland includes red alder (Alnus rubra; FAC), Himalayan blackberry (Rubus DocuSign Envelope ID: C2073BA0-CA13-4596-8BE6-FB745ABA8D08 Critical Area Study & Conceptual Buffer Enhancement Plan Wetland Resources, Inc. #19300 Blue Fern Development – Off-site Benefit Parcel 5 November 21, 2019 armeniacus; FAC). The majority of the dominant species rate “facultative” or wetter, indicating that a hydrophytic vegetative community is present. Typical soils in Wetland A are very dark grayish brown (2.5Y 3/2) silt loam from the surface to 10 inches below. From 10 inches to greater than 18 inches, the soils change to a dark grayish brown (2.5Y 4/2) silt loam with dark yellowish brown redoximorphic features. At the time of the October 2019 investigation, soils were dry. Given the hydrophytic community, hydric soils, and indications of hydrology, the area mapped as off-site Wetland A meets the criteria for a wetland. 2.3.2 Wetland B Cowardin Classification: Palustrine, Forested, Broad-leaved Deciduous, Saturated. City of Renton Classification: Category III (moderate wildlife function) City of Renton Buffer: 75-feet Wetland B is a depressional wetland located in the west-central portion of the investigation area. Dominant vegetation within the wetland includes: red alder (Alnus rubra; FAC), black cottonwood (Populus balsamifera; FAC), red-osier dogwood (Cornus sericea, FACW), Himalayan blackberry (Rubus armeniacus; FAC), giant horsetail (Equisetum telmateia; FACW), lady fern (Athyrium filix-femina; FAC), and reed canarygrass (Phalaris arundinacea, FACW). The majority of the dominant species rate “facultative” or wetter, indicating that a hydrophytic vegetative community is present. Within the wetland, from 0 to 8 inches below the surface, soils are generally a black (10YR 2/1) and a sandy loam texture. The sublayer is a very dark gray (10YR 3/1) with dark yellowish brown (10YR 4/4) redoximorphic features and a sandy loam texture. At the time of the October 2019 investigation, soils were saturated within the top 12 inches. Given the hydrophytic community, hydric soils, and presence of hydrology, the area mapped as off-site Wetland B meets the criteria for a wetland. 2.3.3 Wetland C Cowardin Classification: Palustrine, Scrub-Shrub, Broad-leaved Deciduous, Saturated. City of Renton Classification: Category III (moderate wildlife function) City of Renton Buffer: 75-feet Wetland C is a slope wetland located in the northeastern portion of the investigation area and associated with Stream A. Dominant vegetation within the wetland includes salmonberry (Rubus spectabilis; FAC), andskunk cabbage (Lysichiton americanus; OBL). The majority of the dominant species rate “facultative” or wetter, indicating that a hydrophytic vegetative community is present. Within the wetland, from 0 to 9 inches below the surface, soils are generally a very dark gray (2.5Y 3/1) and a silt loam texture. The sublayer is a dark grayish brown (2.5Y 4/2) silt loam with dark yellowish brown redoximorphic features. At the time of the October 2019 investigation, soils were saturated to the surface with a water table visible at 10 inches below the soil surface. Given the hydrophytic community, hydric soils, and presence of hydrology, the area mapped as off-site Wetland C meets the criteria for a wetland. DocuSign Envelope ID: C2073BA0-CA13-4596-8BE6-FB745ABA8D08 Critical Area Study & Conceptual Buffer Enhancement Plan Wetland Resources, Inc. #19300 Blue Fern Development – Off-site Benefit Parcel 6 November 21, 2019 2.3.4 Non-wetland Areas In non-wetland areas, vegetation includes: red alder (Alnus rubra; FAC), bigleaf maple (Acer macrophyllum; FACU), beaked hazelnut (Corylus cornuta; FACU), Himalayan blackberry (Rubus armeniacus; FAC), , bracken fern (Pteridium aquilinum), reed canarygrass (Phalaris arundinacea; FACW), and sword fern (Polystichum munitum; FACU). Typical soils from soils in areas mapped as upland were a very dark brown (10YR 3/2) with a sandy loam texture in the upper layer. In the sublayer, soils were generally dark brown to dark yellowish brown (10YR 3/4) and a gravelly loam texture. Soils in area mapped as non-wetland were dry at the time of the May 2018 site investigation. This typical soil profile does not meet any hydric soil indicators. No hydrological indicators were observed in the non-wetland areas adjacent to the on-site wetlands. Given the lack of a hydrophytic vegetation community, wetland hydrology, and hydric soils, the areas mapped as non-wetland do not meet the criteria for wetlands. 2.3.5 Stream A Cowardin Classification: Riverine, Upper Perennial, Unconsolidated Bottom, Cobble-Gravel. City of Renton Classification: Type F City of Renton Buffer: 115-feet Stream A bisects the property and is located in the northeastern region of the investigation are and associated with Wetland C. At the time of the October 2019 site investigation, Stream A was flowing, had an average width greater than 2 feet, and exhibited bed and bank characteristics. Based on precipitation preceding the site investigations, WRI believes that Stream A is a perennial feature. Based on information gathered from on-site observations, Stream A is a perennial feature that is consistent with RMC and WAC 222-16-030 Type F Stream Classification. 2.3.6 Stream B Cowardin Classification: Riverine, Intermittent, Streambed, Cobble-Gravel. City of Renton Classification: Type Ns City of Renton Buffer: 50-feet Stream B is a short tributary to Stream A. At the time of the October 2019 site investigation, Stream B was flowing, had an average width of less than 2 feet, and exhibited bed and bank characteristics. Based on precipitation preceding the site investigations, WRI believes that Stream B is an intermittent feature. Based on information gathered from on-site observations, Stream B is an intermittent feature that is consistent with RMC and WAC 222-16-030 Type Ns Stream Classification. 2.4 BUFFER ENHANCEMENT As part of the conservation plan for the off-site benefit parcel, the applicant is proposing to enhance the degraded portions of the buffers associated with all the on-site critical areas. The buffer DocuSign Envelope ID: C2073BA0-CA13-4596-8BE6-FB745ABA8D08 Critical Area Study & Conceptual Buffer Enhancement Plan Wetland Resources, Inc. #19300 Blue Fern Development – Off-site Benefit Parcel 7 November 21, 2019 enhancement will involve removing invasive species and planting native trees and shrubs. The total area of enhancement will be determined prior to final approval. Prior to planting, invasive woody species including (but not limited to) Himalayan blackberry (Rubus armeniacus) and English holly (Ilex aquifolium) will be removed from the buffer enhancement area. Any existing native plants within the buffer shall be retained and protected. The following native shrubs and groundcover will be planted in the buffer enhancement area. Wetland B Buffer Enhancement Common Name Latin Name Size Spacing Douglas Fir Pseudotsuga menziesii 1 gallon 10’ Western red cedar Thuja plicata 1 gallon 10’ Vine maple Acer circinatum 1 gallon 6’ Snowberry Symphoricarpos albus 1 gallon 6’ Sword fern Polystichum munitum 1 gallon 4’ Low Oregon grape Mahonia nervosa 1 gallon 4’ 3.0 FUNCTIONS AND VALUES ASSESSMENT Wetlands and streams in Western Washington perform a variety of ecosystem functions. Included among the most important functions provided by wetlands are stormwater control, water quality improvement, fish and wildlife habitat, aesthetic value, recreational opportunities and education. The most commonly assessed functions and their descriptions are listed below. Assessments of these functions for the project site are provided in the “Analysis” section of this report. Hydrologic Functions Wetlands often function as natural water storage areas during periods of precipitation and flooding. By storing water that otherwise might be channeled into open flow systems, wetlands can attenuate or modify potentially damaging effects of storm events, reducing erosion and peak flows to downstream systems. Additionally, the soils underlying wetlands are often less permeable, providing long-term storage of stormwater or floodflow and controlling baseflows of downstream systems. Stormwater storage capacity and floodflow attenuation are generally a function of the size of the wetland and their topographic characteristics. Water Quality Surface water quality improvement is another important function provided by wetlands. Surface runoff during periods of precipitation increases the potential for sediments and pollutants to enter surface water. Wetlands improve water quality by acting as filters as water passes through them, trapping sediments and pollutants from surface water. Ponded areas within depressional wetlands also allow sediments to drop out of suspension, thereby increasing water quality. Wildlife Habitat Wetlands have potential to provide diverse habitat for aquatic, terrestrial, and avian species for nesting, rearing, resting, cover, and foraging. Wildlife species are commonly dependent upon a variety of intermingled habitat types, including: wetlands, adjacent uplands, large bodies of water, and movement corridors between them. Human intrusion, including development within and DocuSign Envelope ID: C2073BA0-CA13-4596-8BE6-FB745ABA8D08 Critical Area Study & Conceptual Buffer Enhancement Plan Wetland Resources, Inc. #19300 Blue Fern Development – Off-site Benefit Parcel 8 November 21, 2019 adjacent to wetlands, and impacts to movement corridors are the most limiting factors for wildlife habitat functions. 3.1 EXISTING WETLAND CONDITIONS Wetland A is a slope wetland with an overstory of red alder and black cottonwood and an understory dominated by: Himalayan blackberry, hazelnut, vine maple, and swordfern. This wetland provides some hydrologic functions by slowing water velocity, especially during periods of high flows. Vegetation within the wetland assists in filtration of sediments and pollutants. The hydrological and water quality functions of this wetland are limited by the low residence time of water within the wetland. This wetland provides low habitat value, due to limited structural diversity, interspersion of habitats, special habitat features, and low landscape potential to support habitat functions on-site. Overall, this wetland provides a low to moderate level of functions. Wetland B is a depressional wetland with a canopy of red alder and black cottonwood, and understory dominated by: red osier dogwood, salmonberry Himalayan blackberry, and reed canarygrass. This wetland provides some hydrologic functions by slowing water velocity, especially during periods of high flows. Vegetation within the wetland assists in filtration of sediments and pollutants. Similar to Wetland A, this wetland provides low habitat value, due to: limited structural diversity, interspersion of habitats, special habitat features, and low landscape potential to support habitat functions on-site. Overall, this wetland provides a low to moderate level of functions. Wetland C is a small depressional wetland dominated by salmonberry and skunk cabbage. This wetland provides some hydrologic functions by slowing water velocity, especially during periods of high flows. Vegetation within the wetland assists in filtration of sediments and pollutants. The hydrological and water quality functions of this wetland are limited by the low residence time of water within the wetland. This wetland does provide moderate habitat value, partially attributed to its association with Stream A. Overall, this wetland provides a moderate level of functions. 3.2 POST CONSTRUCTION WETLAND FUNCTIONS AND VALUES As mitigation for the proposed development on this property, the applicant is proposing to enhance areas of existing buffer dominated by invasive species. The proposed buffer enhancement plantings will provide a greater diversity of vegetation, facilitating more opportunities for wildlife to find refuge. Additional native, fruit bearing shrubs will provide an increase in food sources for wildlife in the area. This is a vital uplift in functions for all the on-site critical areas. 4.0 PROJECT NOTES Pre-Construction Meeting Mitigation projects are typically more complex to install than to describe in plans. Careful monitoring by a wetland professional for all portions of this project is strongly recommended. Construction timing and sequencing is important to the success of this type of project. There will be a pre-construction meeting on this site between the Permittee, the consulting wetland DocuSign Envelope ID: C2073BA0-CA13-4596-8BE6-FB745ABA8D08 Critical Area Study & Conceptual Buffer Enhancement Plan Wetland Resources, Inc. #19300 Blue Fern Development – Off-site Benefit Parcel 9 November 21, 2019 professional, and laborers. The objective will be to verify the location of erosion control facilities, verify the location of mitigation areas, and to discuss project sequencing. Inspections A wetland professional shall be contracted to periodically inspect the mitigation installation described in this plan. Minor adjustments to the original design may be necessary prior to and during construction due to unusual or hidden site conditions. A City of Renton representative and/or the consulting professional will make these decisions during construction. 5.0 PLANTING NOTES Plant in the early spring or late fall and obtain all plants from a reputable nursery. Care and handling of all plant materials is extremely important to the overall success of the project. The origin of all plant materials specified in this plan shall be native plants, nursery grown in the Puget Sound region of Washington. Some limited species substitution may be allowed, only with the agreement of the landscape designer, wetland professional, and/or City staff. Pre-Planting Meeting Prior to control of invasive species or installation of mitigation plantings, a site meeting between the contracted landscaper and the consulting wetland professional shall occur to resolve any questions that may arise. During this meeting a discussion regarding plant spacing and locations of plant species including wetland verses buffer species shall occur between the landscape contractor and the consulting wetland professional. Handling Plants shall be handled so as to avoid all damage, including: breaking, bruising, root damage, sunburn, drying, freezing or other injury. Plants must be covered during transport. Plants shall not be bound with wire or rope in a manner that could damage branches. Protect plant roots with shade and wet soil in the time period between delivery and installation. Do not lift container stock by trunks, stems, or tops. Do not remove from containers until ready to plant. Water all plants as necessary to keep moisture levels appropriate to the species horticultural requirements. Plants shall not be allowed to dry out. All plants shall be watered thoroughly immediately upon installation. Soak all containerized plants thoroughly prior to installation. Storage Plants stored by the Permittee for longer than one month prior to planting shall be planted in nursery rows and treated in a manner suitable to those species’ horticultural requirements. Plants must be re-inspected by the wetland professional and/or landscape designer prior to installation. Damaged plants Damaged, dried out, or otherwise mishandled plants will be rejected at installation inspection. All rejected plants shall be immediately removed from the site. DocuSign Envelope ID: C2073BA0-CA13-4596-8BE6-FB745ABA8D08 Critical Area Study & Conceptual Buffer Enhancement Plan Wetland Resources, Inc. #19300 Blue Fern Development – Off-site Benefit Parcel 10 November 21, 2019 Plant Names Plant names shall comply with those generally accepted in the native plant nursery trade. Any question regarding plant species or variety shall be referred to the landscape designer, wetland professional, or City staff. All plant materials shall be true to species and variety and legibly tagged. Quality and condition Plants shall be normal in pattern of growth, healthy, well-branched, vigorous, with well-developed root systems, and free of pests and diseases. Damaged, diseased, pest-infested, scraped, bruised, dried out, burned, broken, or defective plants will be rejected. Plants with pruning wounds over 1-inch in diameter will be rejected. Roots All plants shall be balled and burlapped (B &B) or containerized, unless explicitly authorized by the landscape designer and/or wetland professional. Rootbound plants or B&B plants with damaged, cracked, or loose rootballs (major damage) will be rejected. Immediately before installation, plants with minor root damage (some broken and/or twisted roots) must be root- pruned. Matted or circling roots of containerized plantings must be pruned or straightened and the sides of the root ball must be roughened from top to bottom to a depth of approximately half an inch in two to four places. Bare root plantings of woody material are allowed only with permission from the landscape designer, wetland professional and/or City staff. Sizes Plant sizes shall be the size indicated in the plant schedule in approved plans. Larger stock may be acceptable provided that it has not been cut back to the size specified, and that the root ball is proportionate to the size of the plant. Smaller stock may be acceptable, and preferable under some circumstances, based on site-specific conditions. Measurements, caliper, branching, and balling and burlapping shall conform to the American Standard of Nursery Stock by the American Association of Nurserymen (latest edition). Form Evergreen trees shall have single trunks and symmetrical, well-developed form. Deciduous trees shall be single trunked unless specified as multi-stem in the plant schedule. Shrubs shall have multiple stems and be well-branched. Timing of Planting Unless otherwise approved by City staff, all planting shall occur between November 1 and March 1. Overall, the earlier plants go into the ground during the dormant period, the more time they have to adapt to the site and extend their root systems before the water demands of spring and summer. Weeding Existing and exotic vegetation in the mitigation areas will be hand-weeded from around all newly installed plants at the time of installation and on a routine basis throughout the monitoring period. No chemical control of vegetation on any portion of the site is recommended. DocuSign Envelope ID: C2073BA0-CA13-4596-8BE6-FB745ABA8D08 Critical Area Study & Conceptual Buffer Enhancement Plan Wetland Resources, Inc. #19300 Blue Fern Development – Off-site Benefit Parcel 11 November 21, 2019 Site conditions The contractor shall immediately notify the landscape designer and/or wetland professional of drainage or soil conditions likely to be detrimental to the growth or survival of plants. Planting operations shall not be conducted under the following conditions: freezing weather, when the ground is frozen, excessively wet weather, excessively windy weather, or in excessive heat. Planting Pits Planting pits shall be circular or square with vertical sides, and shall be 6” deeper and 12” larger in diameter than the root ball of the plant. Break up the sides of the pit in compacted soils. Set plants upright in pits. Burlap shall be removed from the planting pit. Backfill shall be worked back into holes such that air pockets are removed without adversely compacting down soils. Fertilizer Slow release fertilizer may be used if pre-approved by City of Renton staff. Fertilizers shall be applied only at the base of plantings underneath the required covering of mulch (that does not make contact with stems of the plants). No soil amendment or fertilizers will be placed in planting holes. Staking Most shrubs and many trees DO NOT require any staking. If the plant can stand alone without staking in a moderate wind, do not use a stake. If the plant needs support, then strapping or webbing should be used as low as possible on the trunk to loosely brace the tree with two stakes. Do not brace the tree tightly or too high on the trunk. If the tree is unable to sway, it will further lose the ability to support itself. Do not use wire in a rubber hose for strapping as it exerts too much pressure on the bark. As soon as supporting the plant becomes unnecessary, remove the stakes. All stakes must be removed within two (2) years of installation. Plant Location Colored surveyors ribbon or other appropriate marking shall be attached to the installed plants to assist in locating the plants while removing the competing non-native vegetation and during the monitoring period. Arrangement and Spacing The plants shall be arranged in a pattern with the appropriate numbers, sizes, species, and distribution that are required in accordance with the approved plans. The actual placement of individual plants shall mimic natural, asymmetric vegetation patterns found on similar undisturbed sites in the area. Spacing of the plantings may be adjusted to maintain existing vegetation with the agreement of the landscape designer, wetland professional, and/or City staff. Inspection(s) A wetland professional shall be present on site to inspect the plants prior to planting. Minor adjustments to the original design may be required prior to and during construction. Woodchip Mulch All landscaped areas denuded of vegetation and soil surface surrounding all planting pit areas shall receive no less than 2 to 4 inches of certified woodchip mulch after planting. A layer of woodchip DocuSign Envelope ID: C2073BA0-CA13-4596-8BE6-FB745ABA8D08 Critical Area Study & Conceptual Buffer Enhancement Plan Wetland Resources, Inc. #19300 Blue Fern Development – Off-site Benefit Parcel 12 November 21, 2019 mulch will be placed around the base of each plant in a 3-foot radius and at a depth of 2 to 4 inches. The woodchip mulch shall not be allowed to contact plant stems in order to avoid plant decay and rot. 6.0 PROJECT MONITORING PROGRAM 6.1 REQUIREMENTS FOR MONITORING PROJECT: 1. Initial compliance/as-built report 2. Site inspection (twice per year) for five years 3. Annual reports (one report submitted during each monitored year) Purpose for Monitoring The purpose for monitoring this mitigation project shall be to evaluate its success. Success will be determined if monitoring shows at the end of five years that the definitions of success stated below are met. The property owner shall grant access to the mitigation area for inspection and maintenance to the contracted landscape and/or wetland specialist and City of Renton during the monitoring period or until the project is evaluated as successful. Monitoring Monitoring shall be conducted twice annually for five years in accordance with the approved Mitigation Plan. The monitoring period will begin once the City receives written notification confirming the mitigation plan has been implemented and City staff inspects the site and issues approval of the installation. Vegetation Monitoring Sampling points or transects will be established for vegetation monitoring and photo points will be established from which photos will be taken throughout the monitoring period. Permanent sampling points must be identified on the mitigation site plans in the first monitoring report (they may be drawn on approved plans by hand). Each sampling point shall detail herbaceous, shrub, and tree coverage. Monitoring of vegetation sampling points shall occur once per monitored year. Wetland Hydrology Monitoring To ensure that wetland hydrology is not impacted by the development, the wetland boundaries will be reviewed during the spring monitoring visit of each monitored year. If it appears that any existing wetland areas are no longer saturated or inundated for sufficient duration to support wetland conditions, those areas will be demarcated in the field and depicted on a map. Additional mitigation may need to be provided, as described in the contingency plan in Section 15, below. Photo points No less than four permanent photo points will be established within the mitigation areas. Photographs will be taken from these points to visually record condition of the mitigation areas. Photos shall be taken annually between May 15 and September 30 (prior to leaf drop), unless otherwise specified.

As applicable, monitoring reports must include descriptions / data for: 1. Site plan and vicinity map 2. Historic description of project, including date of installation, current year of monitoring, restatement of enhancement goals, and performance standards 3. Plant survival, vigor, and areal coverage for every plant community (transect or sampling point data), and explanation of monitoring methodology in the context of assessing performance standards 4. Wetland and buffer conditions, e.g., surrounding land use, use by humans, and/or wild and domestic creatures 5. Observed wildlife, including amphibians, avians, and others 6. Assessment of nuisance / exotic biota and recommendations for management 7. Color photographs taken from permanent photo-points that shall be depicted on the monitoring report map 7.0 PROJECT SUCCESS & COMPLIANCE 7.1 CRITERIA FOR SUCCESS Upon completion of the proposed mitigation project, an inspection by a qualified biologist will be made to determine plan compliance. A compliance report will be supplied to the City of Renton within 30 days after the completion of planting. A landscape professional or wetland professional will perform condition monitoring of the plantings in the spring and fall of each monitored year. A written report describing the monitoring results will be submitted to the City after each site inspection of each monitored year. Final inspection will occur five years after completion of this project. The contracted consultant will prepare a report as to the success of the project. 7.2 DEFINITION OF SUCCESS The planting areas shall meet the following performance standards: a) End of Year 1 • 100 percent survival of newly planted species and • Less than 20 percent cover of weedy/invasive species b) End of Year 2 • 80 percent survival of newly planted species • Less than 20 percent cover of weedy/invasive species c) End of Year 3 • At least 50 percent native vegetation coverage within the mitigation areas* • Less than 20 percent cover of weedy/invasive species d) End of Year 5 • At least 80 percent aerial cover of native woody plant species*, DocuSign Envelope ID: C2073BA0-CA13-4596-8BE6-FB745ABA8D08 Critical Area Study & Conceptual Buffer Enhancement Plan Wetland Resources, Inc. #19300 Blue Fern Development – Off-site Benefit Parcel 14 November 21, 2019 • Less than 20 percent cover of weedy/invasive species. *Volunteering native species may be included in the aerial cover calculations. 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 success. 8.0 MAINTENANCE The mitigation areas will require periodic maintenance to remove undesirable species and replace vegetation mortality. Maintenance shall occur in accordance with the approved plans. Chemical control, only if approved by City staff, shall be applied by a licensed applicator following all label instructions. Duration and Extent In order to achieve performance standards, the permittee shall have the mitigation area maintained for the duration of the five-year monitoring period. Maintenance will include: watering, weeding around the base of installed plants, pruning, replacement, re-staking, removal of all classes of noxious weeds (see Washington State Noxious Weeds List, WAC 16-750-005) as well as Himalayan blackberry, and any other measures needed to ensure plant survival. The landscape designer and/or wetland professional shall direct all maintenance. Survival The permittee shall be responsible for the health of 100% of all newly installed plants for one growing season after installation has been accepted by the City of Renton. A growing season for these purposes is defined as occurring from spring to spring (March 15 to March 15 of the following year). For fall installation (often required), the growing season will begin the following spring. The permittee shall replace any plants that are: failing, weak, defective in manner of growth, or dead during this growing season, as directed by the landscape designer, wetland professional, and/or City of Renton staff. Installation Timing for Replacement Plants Replacement plants shall be installed between September 15 and January 15, unless otherwise determined by the landscape designer, wetland professional, and/or City of Renton staff. Standards for Replacement Plants Replacement plants shall meet the same standards for size and type as those specified for the original installation, unless otherwise directed by the landscape designer, wetland professional, and/or City of Renton staff. Replanting Plants that have settled in their planting pits too deep, too shallow, loose, or crooked shall be replanted as directed by the landscape designer, wetland professional, and/or City of Renton staff.

However, limited use of herbicides may be approved depending on site-specific conditions, only if approved by City of Renton staff. Irrigation / Watering Water shall be provided during the dry season (July 1 through October 15) for the first two years after installation to ensure plant survival and establishment. A temporary above ground irrigation system shall be installed within the Stream S buffer enhancement area and Wetland B buffer enhancement area to provide water. Water shall be applied at a rate of 1” of water twice per week for year one and 1” per week during year two. If the mitigation plantings meet 80 percent survival at the end of year two, the system may be removed. General The permittee shall include in general maintenance activities the replacement of any vandalized or damaged signs, habitat features, fences, or other structural components of this mitigation site. 9.0 CONTINGENCY PLAN If 20% of the plants are severely stressed during any of the inspections, or it appears 20 percent 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. 10.0 FENCING & SIGNAGE Per RMC 4-3-050(G)(3)(f)-(h) outlines fencing and signage requirements. Prior to construction, the outer extent of the approved critical area buffer and areas not to be disturbed shall be marked with high visibility orange construction fencing and silt fencing. Subsequently, permanent fencing of the native growth protection area containing critical area shall be installed, along with permanent signs (made of wood or metal, adhered to treated or metal posts). Sign locations and size specifications shall be approved by the city. RMC 4-3-050(G)(3)(h) recommends the following wording for signs, “Protection of this natural area is in your care. Alteration or disturbance is prohibited by law.” 11.0 COST ESTIMATE & SURETY DEVICE A surety device shall be provided to the City of Renton for the period of five years from the completion of the project, in the amount of equal to the estimated cost for plant material and labor. The City of Renton shall release this bond at the end of the five years, upon successful DocuSign Envelope ID: C2073BA0-CA13-4596-8BE6-FB745ABA8D08 Critical Area Study & Conceptual Buffer Enhancement Plan Wetland Resources, Inc. #19300 Blue Fern Development – Off-site Benefit Parcel 16 November 21, 2019 determination for all portions of this mitigation project.

Are the water levels in the entire unit usually controlled by tides except during floods? NO – go to 2 YES – the wetland class is Tidal Fringe – go to 1.1 1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? NO – Saltwater Tidal Fringe (Estuarine) YES – Freshwater Tidal Fringe If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to score functions for estuarine wetlands. 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. NO – go to 3 YES – The wetland class is Flats If your wetland can be classified as a Flats wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet all of the following criteria? ___The vegetated part of the wetland is on the shores of a body of permanent open water (without any plants on the surface at any time of the year) at least 20 ac (8 ha) in size; ___At least 30% of the open water area is deeper than 6.6 ft (2 m). NO – go to 4 YES – The wetland class is Lake Fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? ____The wetland is on a slope (slope can be very gradual), ____The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks, ____The water leaves the wetland without being impounded. NO – go to 5 YES – The wetland class is Slope NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft deep). 5. Does the entire wetland unit meet all of the following criteria? ____The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, ____The overbank flooding occurs at least once every 2 years. For questions 1-7, the criteria described must apply to the entire unit being rated. If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question 8. A Go to First PageDocuSign Envelope ID: C2073BA0-CA13-4596-8BE6-FB745ABA8D08 Wetland name or number ______ Wetland Rating System for Western WA: 2014 Update 4 Rating Form – Effective January 1, 2015 NO – go to 6 YES – The wetland class is Riverine NOTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year? This means that any outlet, if present, is higher than the interior of the wetland. NO – go to 7 YES – The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding? The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO – go to 8 YES – The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within the wetland unit being scored.

Are the water levels in the entire unit usually controlled by tides except during floods? NO – go to 2 YES – the wetland class is Tidal Fringe – go to 1.1 1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? NO – Saltwater Tidal Fringe (Estuarine) YES – Freshwater Tidal Fringe If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to score functions for estuarine wetlands. 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. NO – go to 3 YES – The wetland class is Flats If your wetland can be classified as a Flats wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet all of the following criteria? ___The vegetated part of the wetland is on the shores of a body of permanent open water (without any plants on the surface at any time of the year) at least 20 ac (8 ha) in size; ___At least 30% of the open water area is deeper than 6.6 ft (2 m). NO – go to 4 YES – The wetland class is Lake Fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? ____The wetland is on a slope (slope can be very gradual), ____The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks, ____The water leaves the wetland without being impounded. NO – go to 5 YES – The wetland class is Slope NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft deep). 5. Does the entire wetland unit meet all of the following criteria? ____The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, ____The overbank flooding occurs at least once every 2 years. For questions 1-7, the criteria described must apply to the entire unit being rated. If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question 8.

Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year? This means that any outlet, if present, is higher than the interior of the wetland. NO – go to 7 YES – The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding? The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO – go to 8 YES – The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area. HGM classes within the wetland unit being rated HGM class to use in rating Slope + Riverine Riverine Slope + Depressional Depressional Slope + Lake Fringe Lake Fringe Depressional + Riverine along stream within boundary of depression Depressional Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE If you are still unable to determine which of the above criteria apply to your wetland, or if you have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

Are the water levels in the entire unit usually controlled by tides except during floods? NO – go to 2 YES – the wetland class is Tidal Fringe – go to 1.1 1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? NO – Saltwater Tidal Fringe (Estuarine) YES – Freshwater Tidal Fringe If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to score functions for estuarine wetlands. 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. NO – go to 3 YES – The wetland class is Flats If your wetland can be classified as a Flats wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet all of the following criteria? ___The vegetated part of the wetland is on the shores of a body of permanent open water (without any plants on the surface at any time of the year) at least 20 ac (8 ha) in size; ___At least 30% of the open water area is deeper than 6.6 ft (2 m). NO – go to 4 YES – The wetland class is Lake Fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? ____The wetland is on a slope (slope can be very gradual), ____The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks, ____The water leaves the wetland without being impounded. NO – go to 5 YES – The wetland class is Slope NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft deep). 5. Does the entire wetland unit meet all of the following criteria? ____The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, ____The overbank flooding occurs at least once every 2 years. For questions 1-7, the criteria described must apply to the entire unit being rated. If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question 8.

Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year? This means that any outlet, if present, is higher than the interior of the wetland. NO – go to 7 YES – The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding? The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO – go to 8 YES – The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area. HGM classes within the wetland unit being rated HGM class to use in rating Slope + Riverine Riverine Slope + Depressional Depressional Slope + Lake Fringe Lake Fringe Depressional + Riverine along stream within boundary of depression Depressional Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE If you are still unable to determine which of the above criteria apply to your wetland, or if you have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.
