PREPARED FOR RICK GROSS PO BOX 3010 SEQUIM, WA 98382 PREPARED BY BGE ENVIRONMENTAL LLC 2102 BRASHEM AVE BREMERTON, WA 98310 360.710.6066 www.bgeenvironmental.com BGE21_0300 BGE ENVIRONMENTAL, LLC MAY 25, 2021 1 | PAGE 41 WOLF RD HABITAT MANAGEMENT PLAN INTRODUCTION The proposed project is redevelopment over the existing use, slightly larger in area. The existing use is non-conforming to the standard shoreline buffer of 150 ft and the stream buffer of 50 ft. There are no other reasonable alternatives to support residential use of the parcel that results in avoiding the stream and shoreline buffer. Buffer modifications to the stream are defined as establishing the buffer to the existing access and defined parking area. The impact is unavoidable. The project respectfully requests a buffer reduction of forty (40) percent to comply with access and parking standards. Vegetation alteration requires felling three mature red alders. The resultant stream buffer is established to the perimeter of use and results in a buffer not less than 30 ft in width. The buffer modification is not likely to have an adverse impact to the stream since the buffer is degraded and has a low function supporting the associated Type N water, Chapter 18.22.640 of the Jefferson County Code (JCC). The 5 ft setback is respected. A net gain of the buffers function and value is anticipated with the proposed mitigation as recovery of native cover to the buffer. The project respectfully requests a buffer reduction not less than 75 percent of the standard shoreline buffer (JCC Chapter 18.25.270). The buffer is established at 112.5 ft. However, the drainfield is closer to the shoreline than the established buffer. Shoreline buffer vegetation disturbances include three mature Douglas fir, a coppiced hazelnut cluster, and some osoberry. Upon construction retreat, the drainfield area shall provide dual use as a common area to the shoreline. The 10 ft setback is respected. The proposed mitigation equally restores portions of the shoreline buffer. The project preserves the ecological niche of the freshwater to marine water confluence. No net loss of ecological functions and processes is achieved. Mitigation for the buffer reductions is provided as 1,200 sq ft of restoration to degraded buffer. Mitigation includes coniferous trees to the stream corridor and targets the lack in understory with the installation of native shrubs and dense groundcover This Habitat Management Plan (HMP) is provided for unavoidable buffer reductions to a Type N water and the marine shoreline to Fisherman Harbor. The application of standards and regulations applied for the project were completed under the guidance of JCC Chapter 18.22 Critical Areas and JCC Chapter 18.25 Shoreline Master Program and includes the following. • Assessment of existing conditions; • Assessment of priority habitat, species within the vicinity of the project; • Impact assessment; • Analysis of mitigation sequencing; and • Mitigation plan. BGE ENVIRONMENTAL, LLC MAY 25, 2021 2 | PAGE 41 WOLF RD HABITAT MANAGEMENT PLAN EXISTING CONDITIONS The subject parcel is irregularly shaped, elongated from the north to south. The topography is a gradual decline from the access to the existing structure and surrounding use. This existing use is delineated in the east with a gradual top-of-slope to a moderate ravine and a Type N water. To the south, the break in slope is more gradual, steepening with the approach as a moderate bluff to the shoreline. Ordinary High Water Mark (OHWM) is delineated to the toe-of-slope along at the vertical drop from the bank. The parcel hosts a structure aligned along the western property boundary on a knoll like setting, see Exhibit A. The existing and historic use is well observed to the surface. The entire parcel setting is beneath a closed canopy of mixed mature native coniferous and deciduous trees. Species include Douglas fir, Bigleaf maple, Western red cedar, and red alder. An understory is absent within the use area surrounding the structure. Elsewhere the vegetation is rich with a dense cover of Pacific rhododendron, evergreen huckleberry, salmonberry, osoberry, oceanspray, red elderberry, and salal. Groundcovers include bracken fern, sword fern, lady fern, bleeding heart, chickweed, ducks foot, and a variety of grasses and weeds. Other nonnative, noxious, or invasive species include hedge laurel and bamboo. A path is established along the creek to the shoreline. The path crosses the creek with a crude wooden bridge. A ladder at the shoreline provides some safety for the final drop to the beach. The bank is a natural vertical from the nearshore to the beach. The OHWM is established at the toe-of-slope. Surrounding land use include high, moderate, and low land use. Character is rural residential with large undeveloped land tracts. Services are Port Ludlow, Chimacum, Poulsbo. The parcel habitat potential is native and naturalized species. BGE ENVIRONMENTAL, LLC MAY 25, 2021 3 | PAGE 41 WOLF RD HABITAT MANAGEMENT PLAN BACKGROUND INFORMATION RESEARCH AND DATA SYNTHESIS Background research and data review are essential for the assessment of known and documented habitat and species within the vicinity of the project site. Data researched included relevant mapping from U.S. Fish and Wildlife Service, Washington State Department of Fish and Wildlife (WDFW), and Washington Department of Natural Resources (WDNR) Natural Heritage Database. Reference sources are summarized and documented in Appendix A. U.S. FISH & WILDLIFE SERVICE NATIONAL WETLAND INVENTORY (NWI) The US Fish and Wildlife Service National Wetland Inventory identifies intertidal estuarine waters to Fisherman Harbor. These waters are classified under the Cowardin system as E2USN. System Estuarine (E): The Estuarine System consists of deepwater tidal habitats and adjacent tidal wetlands that are usually semi-enclosed by land but have open, partly obstructed, or sporadic access to the open ocean, and in which ocean water is at least occasionally diluted by freshwater runoff from the land. The salinity may be periodically increased above that of the open ocean by evaporation. Along some low-energy coastlines, there is appreciable dilution of sea water. Subsystem Intertidal (2): The substrate in these habitats is flooded and exposed by tides; includes the associated splash zone. Split Class Unconsolidated Shore (US): Includes all wetland habitats having two characteristics: (1) unconsolidated substrates with less than 75 percent areal cover of stones, boulders or bedrock and; (2) less than 30 percent areal cover of vegetation. Landforms such as beaches, bars, and flats are included in the Unconsolidated Shore class. Water Regime Regularly Flooded (N): Tides alternately flood and expose the substrate at least once daily. BGE ENVIRONMENTAL, LLC MAY 25, 2021 4 | PAGE 41 WOLF RD HABITAT MANAGEMENT PLAN U.S. FISH & WILDLIFE SERVICE IPAC TRUST RESOURCES REPORT The U.S. Fish & Wildlife IPaC Trust Resources Report identifies federally listed species and designated critical habitats, Essential Fish Habitat (EFH), and/or Distinct Population Segment (DPS).

BGE ENVIRONMENTAL, LLC MAY 25, 2021 6 | PAGE 41 WOLF RD HABITAT MANAGEMENT PLAN IMPACT ASSESSMENT The proposed project is redevelopment over existing, see Exhibit B. The site design is considerate to all JCC Titles providing drainfield, access and reuse to the structural footprint. Due to the size, shape, and bounding critical areas, impacts to the stream and shoreline buffers are unavoidable. Redevelopment is proposed as the most reasonable alternative available to support the residential use. The assessed impacts are within a building envelop considered existing nonconforming, see Exhibit C. To comply with current standards for the redevelopment, reduction of buffers cannot be avoided. Mitigation is applied to ensure that the reduced buffer(s) will not adversely affect the habitat function and values to the stream, Fish and Wildlife Conservation Areas (FWCA), and that no net loss of shoreline ecological function is achieved. The assessed impacts are located to historic use. This area is degraded having compromised surfaces noted as typical paths and random materials (wood, broken concrete, denuded surfaces, lawn, weeds, and forbs). Mixed mature native trees dominate the parcels complexity with a closed canopy. Outside of the use areas, the vegetation cover is rich native shrubs and groundcovers. Actions of the project resulting in stream buffer impacts is from the establishment of the parcel access off Wolf Rd, see Exhibit C. There is no vegetation to the surface. Three mature red alders are present to the eastern side and need to be removed for construction logistics and the establishment of on-site parking. The established stream buffer is at the approximate edge of existing use. The resultant buffer ranges from 30 to 42 ft from stream. The 5 ft setback is respected. Similarly, the shoreline buffer impacts are limited to the existing use, see Exhibit C. The new structure is slightly larger than the existing but is not set closer to the shoreline. The remainder of the buffer impact is to surfaces that are mostly void of vegetation, exposed, and utilized for residential parcels. There is no significant change to the use and character is anticipated. The new structure is located off (landward) of the established shoreline buffer of 112.5 ft. The 10 ft set back is applied, see Exhibit D. The drainfield is proposed in the shoreline buffer, below the 112.5 ft buffer. As we understand the design, two mature Douglas firs will be cut for the needs of the drainfield, however the stumped roots will remain intact. Any additional vegetation removed in this area is a coppiced Hazelnut and some osoberry. The vegetation impact is minimal apart from the two conifers. Post construction the drainfield is pervious, commonly grassed surface. It is reasonable to identify this area as a dual use providing the common area to the shoreline. BGE ENVIRONMENTAL, LLC MAY 25, 2021 7 | PAGE 41 WOLF RD HABITAT MANAGEMENT PLAN MITIGATION SEQUENCING Permitted uses shall be designed and conducted to minimize, in so far as practical, any resultant damage to the ecology and environments. Impacts shall be mitigated according to Chapter 18.22.660 JCC, in a sequential analysis to avoid, minimize and mitigate. The mitigation analysis sequence for the shoreline in question is provided below. MITIGATION MEASURE MITIGATED ACTION(S) AVOID the impact altogether by not taking a certain action or parts of an action • The project cannot completely avoid all impacts to the shoreline buffer by avoiding certain actions or parts of actions and still have a viable project. MINIMIZE impacts by limiting the degree or magnitude of the action and its implementation by using appropriate technology or by taking affirmative steps to avoid or reduce impacts • The magnitude of the project has already been minimized to the maximum extent practicable while still maintaining enough developable area to have a viable compliant project. RECTIFY the impact by repairing, rehabilitating, or restoring the affected environment • The affected environment will generally not be able to be re-established, rehabilitated or restored. Impacts are permanent. REDUCE or eliminate the impact over time by preservation and maintenance operations • The affected environment will generally not be able to be re-established, rehabilitated or restored. Impacts are permanent. COMPENSATE for the impact by replacing, enhancing, or providing substitute resources or environments • Plant a minimum of twelve (12) native conifers. • Restore areas of the established buffer currently degraded or compromised in native vegetation cover. MONITOR the impact and the compensation project and take appropriate corrective measures • Implementation of mitigation plan completed prior to receipt of Certificate of Occupancy pending seasonal conditions persist. • Five-year post planting compliance record. BGE ENVIRONMENTAL, LLC MAY 25, 2021 8 | PAGE 41 WOLF RD HABITAT MANAGEMENT PLAN MITIGATION This parcel is defined with a historic residential use. Outside of the observable use area exists a closed native canopy and complex understory to a Type N water and the moderate bluff shoreline to Fisherman Harbor. Project impacts are located to the existing use. Buffer modifications are applied as the minimum necessary to delineate the existing use and accommodate upgrades with the redevelopment. Mitigation potential is observed to the perimeter of the existing use which is delineated as the established stream and shoreline buffer, see Exhibit E. The mitigation consists of twelve (12) native conifers and a variety of shrubs and groundcovers. The approximate area of restoration is 1,200 sq ft. A total of fifty-four (54) shrubs should be planted in groups with a dense spacing. The remainder of the mitigation area is to be infilled with a mix of evergreen, fruiting, and flowering groundcovers. The established buffer shall be retained as a rich native complex. Assess shall be retained and respects for shoreline access. Native landscaping to the structure and associated use is recommended. Choose native, low maintenance species of trees, shrubs, and groundcovers. Use deciduous, broad leaf evergreen, and coniferous species. Wildflowers are aesthetically pleasing and are excellent habitat niches for hummingbirds and butterflies. Denuded or bare soils should be avoided. BGE ENVIRONMENTAL, LLC MAY 25, 2021 9 | PAGE 41 WOLF RD HABITAT MANAGEMENT PLAN GOALS AND STANDARDS GOAL Restore 1,200 sq ft of stream and shoreline buffer with native trees, shrubs and groundcover. PERFORMANCE STANDARDS The standards listed below will be used to judge the success of the plan over time. If the standards are met at the end of the five-year monitoring period, Jefferson County shall approve as conditioned. SURVIVAL YEAR ONE 100% survival of all planted individuals at the end of Year One per the supplier contract. This standard may be met through establishment of installed plants or by replanting as necessary to achieve the required numbers. YEAR FIVE 100% survival of all planted trees at the end of Year Five. 80% survival of all planted shrubs at the end of Year Five. This standard may be met through establishment of installed plants or by replanting as necessary to achieve the required numbers. NOTE: Individual groundcover species is difficult to track. Areas of significant mortality shall be estimated and replanted at densities enough to establish 100 percent cover to the established buffer. BGE ENVIRONMENTAL, LLC MAY 25, 2021 10 | PAGE 41 WOLF RD HABITAT MANAGEMENT PLAN NATIVE WOODY VEGETATION COVER YEAR THREE Achieve at least 70% cover of native vegetation by the end of Year Three. Volunteer native species may count towards this standard. YEAR FIVE Achieve 100% cover of native vegetation by the end of Year Five. Volunteer native species may count towards this standard. INVASIVE SPECIES REMOVAL AND CONTROL No tolerance of invasive species in the established wetland and stream buffer. Species intolerance includes all Class A, B, or C noxious weeds as listed by the Washington state Noxious Weed Control Board. A conceptual planting plan is provided in Exhibit E. Adaptive management is acceptable for placement and species alternatives with prior approval from BGE. Once planted the details and vegetation specifications shall be documented in an as-built. BGE ENVIRONMENTAL, LLC MAY 25, 2021 11 | PAGE 41 WOLF RD HABITAT MANAGEMENT PLAN PLANTING DETAILS AND SPECIFICATIONS The provided planting plan is conceptual for the restoration area, see Exhibit E. Generally the species prescribed are chosen to have a high probability of establishment in the landscape and provide natural function and parcel aesthetics. Alternatives are acceptable as long the species are native and commonly occur within the Central Hood Canal lowlands.

BGE ENVIRONMENTAL, LLC MAY 25, 2021 13 | PAGE 41 WOLF RD HABITAT MANAGEMENT PLAN EROSION CONTROL & SITE PREPARATION Temporary erosion and sediment control (TESC) measures shall be implemented under the guidance of approval conditions using BMP’s outlined in the project’s SWPPP and TESC Plan prepared by the Project Engineer. Approval by the responsible Restoration Specialist prior to mowing, hand-clearing and planting activities on-site is recommended. PLANT SCHEDULING, SPECIES & DENSITY Planting should occur between October 1 and March 31. All materials to be used on the site will be nursery grown stock from a reputable, local source. Only native species are to be used; no hybrids or cultivars will be allowed. All plant material shall be inspected by the consultant/contractor upon delivery. Plant material provided will be typical of their species or variety and shall be sound, healthy, vigorous plants free from defects, and all forms of disease and infestation. Plant material not conforming to the specifications will be rejected and replaced by the contractor or supplier. Rejected plant materials shall be immediately removed from the site. PRODUCT HANDLING, DELIVERY & STORAGE All precautions customary in good trade practice shall be taken in preparing plants for moving. Workmanship that fails to meet industry standards will be rejected. Plants will be packed, transported, and handled with care to ensure protection against injury and from drying out. If plants cannot be planted immediately upon delivery they should be protected with soil, wet peat moss, or in a manner acceptable to the project biologist. Plants, fertilizer, and mulch not installed immediately upon delivery shall be secured on the site to prevent theft or tampering. No plant shall be bound with rope or wire in a manner that could damage or break the branches. Plants transported on open vehicles should be secured with a protective covering to prevent windburn. PREPARATION & INSTALLATION OF PLANT MATERIALS Contractor shall verify the location of all elements of the mitigation plan with the materials count upon clearing of invasive vegetation and prepping surface for installation. Plant quantities are BGE ENVIRONMENTAL, LLC MAY 25, 2021 14 | PAGE 41 WOLF RD HABITAT MANAGEMENT PLAN based on field measurements and density calculations which have a standard error association with planning and implementation. Locations of proposed materials are conceptual, representation natural distribution character, and may be moved for consistency in final grade, topographical features, and defined use. All installed vegetation will be marked to a site plan for general areas and quantities. The documented actions will be used to produce an as-built once the mitigation actions are complete. Circular plant pits with vertical sides will be excavated for all bare root and container stock. The pits should be at least 6 inches greater in diameter than the root mass or container. The pit should accommodate the entire root system. The bottom of each pit will be scarified to a depth of 4 inches. Set plant material upright in the planting pit to proper grade and alignment. Water plants thoroughly midway through backfilling and add slow release Agroform tablets. Water pits again upon completion of backfilling. No filling should occur around trunks or stems. Do not use frozen or muddy mixtures for backfilling. Form a ring of soil around the edge of each planting pit to retain water. Once planted, the entire area shall be covered with clean straw or mulch to a depth where the denuded surface is not visible. BGE ENVIRONMENTAL, LLC MAY 25, 2021 15 | PAGE 41 WOLF RD HABITAT MANAGEMENT PLAN MONITORING This monitoring program is designed to track the success of the mitigation actions over time by measuring the degree to which the performance standards listed above are being met. Monitoring for evaluation of the standards is defined below. YEAR DATE MAINTENANCE REVIEW PERFORMANCE MONITORING REPORT DUE Implementation/Planting: As-built production and submittal within 60 days to Jefferson County Department of Community Development 1 Spring X Fall X X 2 Spring X Fall X X 3 Spring X Fall X X 4 Spring X Fall X X 5 Spring X Fall X X X FINAL Monitoring shall occur annually for all monitoring years to ensure vegetation is establishing, healthy, and likely to sustain ecological integrity for long term protection on shoreline ecological processes. Quantitative monitoring shall occur for all years. A progress report documenting qualitative and quantitative measures of success cumulated for each monitoring year will be submitted to Jefferson County for Year 5, for consideration of approval as conditioned. Additional monitoring needs are at the recommendation of BGE and discretion of Applicant, Owner. During monitoring inspection, BGE Environmental shall quantify plant survival, estimate groundcover establishment, and measure native and invasive cover. Photo-stations shall be established once the planted materials are in place. Cover measurements will be completed as BGE ENVIRONMENTAL, LLC MAY 25, 2021 16 | PAGE 41 WOLF RD HABITAT MANAGEMENT PLAN visual estimates and/or random sectional plots within the planting area. Areas outside the plots, if used, will be visually monitored to verify that performance standards are being met, with attention to invasive species at the perimeter (off-site). Monitoring will occur in the late summer or early fall and will record the following. 1) Counts of surviving and dead/dying vegetation by species in the planting areas. 2) Estimates of groundcover planting survival, noting any areas of significant mortality. 3) Estimates of native woody species cover within random plot. 4) Estimates of invasive species cover within random plot. 5) Photographic documentation from permanent stations. 6) Intrusions into the planting areas, erosion, vandalism, trash, and other actions detrimental to the overall health of the planting area. 7) Recommendations for maintenance in the mitigation area. BGE ENVIRONMENTAL, LLC MAY 25, 2021 17 | PAGE 41 WOLF RD HABITAT MANAGEMENT PLAN MAINTENANCE The applicant is committed to compliance with the proposed restoration plan and overall success of the project. The site will be maintained for five years following completion of the plant installation. Anticipated actions and necessary guidelines to meet the performance standards are as follows: 1) Replace each plant found dead in the summer monitoring visit after the first year of planting and subsequent years if mortality approaches 20 percent of the total individuals. 2) Invasive species maintenance plan: a. Any invasive species that crop up, Himalayan blackberry, Japanese knotweed, Scotch broom, English ivy, or other invasive vegetation, will be dug out by hand to prevent establishment and disruption of native species. 3) At least twice a year, hand remove all competing weeds and weed roots from beneath each installed plant and any desirable volunteer vegetation to eighteen (18) inches from the main plant stem. Weeding should occur as needed during the spring and summer. Frequent weeding will result in lower mortality and lower plant replacement costs. 4) Do not weed the area near the plant bases with string trimmer (weed whacker). 5) Mulch the weeded areas beneath each shrub with wood chips as necessary to maintain a minimum two-inch thick, eighteen-inch diameter mulch ring around shrubs. 6) Temporary irrigation may be necessary and installed at the recommendation of the restoration specialist. Irrigation shall operate to ensure that the planted area receives a minimum of one inch of water per week from June 1 through September 30. BGE ENVIRONMENTAL, LLC MAY 25, 2021 18 | PAGE 41 WOLF RD HABITAT MANAGEMENT PLAN CONTINGENCY There is an applied standard error of success applied to the buffer enhancement area due to the existing drainfield. As the exact area (boundary) of the drainfield is unknown, the limits of the planted buffer may suffer mortality. In the case that survival consistently fails after replacing individual post installation year one, the limits of the enhancement should be reviewed by BGE for contingency measures to ensure no net loss is achieved. If any part of the planting area fails to satisfy the goals and performance standards of this plan to such an extent that the failure cannot be adequately addressed through standard maintenance activities, a contingency plan shall be developed. A detailed contingency plan cannot be developed until the specific items that need to be addressed are known. Compliance with the installation procedures and maintenance plans are measures to properly promote a successful restoration. Where the performance is less than satisfactory, attention shall be given to, but not limited to, soil conditions, species installation, and temporal variations. Adaptive management actions taken to ensure success, when practical, are an acceptable means to ensure survival and growth of the planted species.

This report includes information that the Washington Department of Fish and Wildlife (WDFW) maintains in a central computer database. It is not an attempt to provide you with an official agency response as to the impacts of your project on fish and wildlife. This information only documents the location of fish and wildlife resources to the best of our knowledge. It is not a complete inventory and it is important to note that fish and wildlife resources may occur in areas not currently known to WDFW biologists, or in areas for which comprehensive surveys have not been conducted. Site specific surveys are frequently necesssary to rule out the presence of priority resources. Locations of fish and wildlife resources are subject to variation caused by disturbance, changes in season and weather, and other factors. WDFW does not recommend using reports more than six months old.
