Peebles Court Shelton,Washington 1.0 PROJECT DESCRIPTION The details of a Habitat Management Plan prepared for John L. Laramie for the above referenced property (Parcel No. 321275400105) are discussed in full in this report. The site address is 60 E Peebles Court, Shelton, Washington, 98588. The site is found in the SE 1/4 of Section 27 Township 21 North, Range 3 West (See Figure 1, Site Vicinity Map). The purpose of this Habitat Management Plan (HMP) is to address potential impacts resulting from the proposed construction of a 1192 square foot single-family residence (SFR) and 450 square foot access road within a lot encompassed by the regulated buffer of a fishbearing stream. The stream meets criteria for a Type 3 stream, requiring 150 feet of undisturbed buffer with an additional 15-foot building setback. The SFR is proposed 78 feet from the stream at the nearest point. The septic system already exists onsite and is located on the northeast side of the lot. The objectives of this HMP are as follows: ■ To evaluate the potential adverse effects to critical area functions as well as fish and wildlife habitat resulting from the establishment of the SFR and access road within the Type 3 stream buffer. Emphasis is placed on the possible loss of habitat for any listed species found to be residing in the vicinity of the parcel. ■ To identify possible mitigation measures that could be implemented to offset the adverse effects resulting from the establishment of the SFR and access road collectively occupying an area of 1642 square feet within the Type 3 stream buffer. 2.0 PROPERTY DESCRIPTION The ownership is less than one acre in size, roughly rectangular in shape, and oriented northwest to southeast. The stream meanders within the southern portion of the parcel, with the associated 150-foot stream buffer encompassing the entire lot. The stream flows westerly through the parcel, and drains into Cranberry Creek approximately 500 feet west of the ownership. The lot is accessed by E Peebles Court to the north and is bordered to the west, east, and south by single- family residential lots of similar size and shape. A mobile home was removed from the portion of the parcel north of the stream several years ago. This area has been maintained as an open area. Vegetation throughout the majority of the northern portion of the parcel is comprised of herbaceous and shrub species including Scotch PO Box 2854, Belfair, WA 98528 cell:360-620-0618, Office: 360-372-2421 e-mail: boad40@peoplepc.com Laramie HNil? November, 2006 Page 2 broom, Himalayan blackberry, and lawngrasses. Vegetation south of the stream has been left well in tact and contains an overstory of primarily Douglas fir with an understory comprised of salal and sword fern. Topography within the lot is generally flat, with a low gradient slope toward the type 3 stream. 3.0 APPLICABLE SETBACKS The project site is within the jurisdiction of Mason County. Ordinance 17.01.110 identifies Fish and Wildlife Habitat Conservation Areas adopted by Mason County. The applicable setback for this project is as follows: Habitat Type Buffer Building Setback from Buffer Type 3 Stream 150' 15' 4.0 DESCRIPTION OF HABITAT AND SPECIES 4.1 Puget Sound Chinook(Oncorhynchus tshawytsha)-Threatened Listed as threatened since March 24, 1999 adult Puget Sound Chinook spawn in several rivers and streams flowing into Puget Sound. The type 3 fishbearing stream is a tributary to Cranberry Creek. Cranberry Creek was recently excluded form NOAA's Fisheries Northwest Region Critical Habitat Designations for West Coast Salmon and Steelhead in Washington in August, 2005. Although the stream may be accessible to Puget Sound Chinook, suitable habitat is not present due to the limited size and lack of sufficient flow during the spawning period. This project is not likely to have adverse impacts on Puget Sound Chinook due to the lack of suitable habitat and proposed mitigation. No impacts to water quality are predicted with proposed mitigation. 4.2 Bull Trout(Salvelinus malma)-Threatened Bull trout typically inhabit very cold, clear headwater streams at high elevations that are supported by snowmelt. For spawning and early rearing, bull trout require loose, clear gravel, relatively free of fine sediments. Although the substrate may be suitable for Bull Trout spawning, the lower elevation and relatively high temperature of the type 3 stream is not suitable habitat for Bull Trout. Given the lack of suitable habitat and no documented occurrence the proposed project is not likely to have any adverse impacts on bull trout. 4.3 Bald Eagle (Haliaeetus leucocephalus)- Threatened Habitat areas associated with Bald Eagle include uneven aged coniferous stands with some old- growth components. Nests are typically constructed in larger trees with dead or broken tops providing an unobstructed view of nearby water. Snags and trees with exposed lateral limbs, or dead tops are used as perches and defense stations. PO Box 2854, Belfair,WA 98528 cell:360-620-0618, Office: 360-372-2421 e-mail: boad40@peoplepc.com Laramie HMP November,2006 Page 3 There are no documented Bald Eagle nesting sites in the vicinity of the project area. The area proposed for the SFR and access road is devoid of any overstory components. Recommended overstory plantings recommended in Section 6.3 should improve the potential for use of the site by Bald Eagle in the future by enhancing overstory habitat within the site. As no important habitat features are to be removed,this project will have no adverse impacts on bald eagles. 4.4 Marbled Murrelet(Brachyramphus marmoratus)-Threatened Marbled Murrelets are typically associated with coastal habitats and nest in old-growth forests. Murrelets may fly as far as 50 miles inland to nest, however the average distance is roughly 5- miles from nest to sea. It is only during the summer breeding months that they are commonly found inland. During non-nesting seasons they live at sea. Murrelets require tall mossy trees in coniferous old growth forests with cavities on thick branches where they can construct a cup nest 20-40 meters above the forest floor. Murreletts have been documented laying eggs on rocky ground habitats only when a sufficient forest is unavailable. There are no documented nesting sites surrounding the project site. No potential nesting trees are within the project area. This project will likely have no adverse impact on Marbled Murrelet given there are no documented nesting sites or potential nesting trees in the vicinity of the project area. 5.0 ANALYSIS OF EFFECTS The project lies within the regulated buffer of a Type 3 stream. Project scale in the protected area is as follows: Development Type Habitat Type Project scale Single Family Residence Type 3 Stream Buffer 1192 sq. ft. Gravel Access Road Type 3 Stream Buffer 450 sq. ft Total Type 3 Stream Buffer 1642 sq. ft.

Proposed building site. 5.1 Vegetation Disturbance The access road and SFR are proposed in a portion of the lot that has been maintained as an open area interspersed with Scotch broom and Himalayan blackberry. No native vegetation will be removed for the proposed project. With recommended planting of native vegetation described in Section 6.3, the project will likely have a net benefit of vegetation abundance and diversity within the lot. 5.2 Designated Critical Habitat for Salmonids Designated Critical Habitat for Salmonids is not within the vicinity of the project area. Therefore, none of the proposed actions are likely to destroy or adversely modify designated critical habitat. Actions described in this plan are not expected to jeopardize the continued existence of any listed species. 5.3 Noise Pollution A slight increase in noise from construction activities is likely to occur during daylight construction hours. No nesting sites are located within the radii of concern that would be impacted by noise associated with the establishment of the SFR and access road. 5.4 Temporary Increase in Sediment and Turbidity During Construction The proposed work has the potential to temporarily increase turbidity and suspended sediment within the project area. Best Management Practices have been recommended in Section 6.2 to minimize the adverse effects to sediment supply and turbidity during project implementation. 5.5 Light and Glare PO Box 2854, Belfair, WA 98528 cell:360-620-0618, Office: 360-372-2421 e-mail: boad40@peoplepc.com Laramie HMI' November,2006 Page 5 The proposed project will result in an increase in light and glare commonly associated with residential construction and land use. The majority of wildlife activity likely occurs south of the stream, where the vegetative buffer has been left in tact. The vegetative buffer to be enhanced between the proposed project and the stream is expected to shield the majority of the stream from increased light and glare. No impacts to the use of the site by wildlife species is likely to result from light and glare associated with this project. 6.0 MITIGATION MEASURES 6.1 Preservation of Critically Important Plants The remainder of the Type 3 stream buffer, outside of the proposed SFR and access road, will be preserved and remain in tact or enhanced with native vegetation. The proposed SFR is located 78 feet from the stream at the nearest point, this is the greatest possible distance from the stream given the limited size of the lot. 6.2 Best Management Practices Recommended Best Management Practices for this project are as follows: • Perform excavation and site preparation work during dry weather. • Install silt fencing between the work area and the stream to prevent erosion and siltation of waters. • Minimize amount of erodible soils at any given time to the maximum extent feasible. • Check all equipment daily for leaks. Refueling and lubrication of equipment should occur off site. Do not store any fuel, lubricants, chemicals, or hazardous substances outside overnight within the project area. • Do not apply any chemicals when there is a possibility of rain. • Comply with all permits and requirements of governing authority. 6.3 Enhancement Recommendations It is recommended that a 50-foot strip of the stream buffer, parallel to the stream, between the SFR and the Type 3 stream be enhanced with native vegetation. The enhancement of a moderately dense forested and shrub community within the suggested portion of the open area is likely to improve wildlife utilization and riparian function of the site. The area selected as the mitigation zone occupies an area of approximately 4,500 square feet. Native Plantings To offset impacts associated with the establishment of the SFR and access road and the displaced stream buffer, it is recommended that the mitigation zone be enhanced with native plants. The following species are recommended: Trees: western red cedar(Thuja plicata) Douglas fir(Pseudotsuga menziesii) Shrubs: Oregon grape (Mahonia nervosa) PO Box 2854, Belfair, WA 98528 cell:360-620-0618, Office: 360-372-2421 e-mail: boad40@peoplepc.com Laramie HMP November,2006 Page 6 salal (Gaultheria shallon) evergreen huckleberry (Vaccinium ovatum) nootka rose(Rosa nutkana) salmonberry(Rubus spectabilis) Pacific Willow(Salix lusida) Hooker willow(Salix hookeriana) Scouler willow(Salix scouleriana) Sitka willow(Salix sitchensis) beaked hazelnut(Corylus cornuta) Indian plum (Oemleria cerasiformis) oceanspray(Holodiscus discolor) Pacific ninebark (Physocarpus capitatus) California black currant(gibes bracteosum) western thimbleberry(Rubus parviflorus) red elderberry(Sambucus racemosa) Ferns: sword fern(Polystichum munitum) Groundcover: kinnikinnik (Arcostaphylus uva-ursi) coastal strawberry(Fragaria chiloensis) Native Planting Guidelines It is recommended that plantings be installed within the identified mitigation zone to achieve the following densities. A minimum of 1 tree species, five shrub species and one groundcover species from the above list are recommended. trees- 10' on center shrubs-5' on center ferns- 3' on center herbaceous groundcover—6 inches on center These densities will provide a moderately dense, structurally diverse plant community within the mitigation zone.

LAY'-.��m�� tiYf R Photo 2. Mitigation zone. Typically, planting should occur during winter dormancy. The optimum time for planting is during February and March, however, the need to complete the project in a timely manner may call for planting to occur outside optimum time periods. A monitoring program is recommended to insure project effectiveness. 5.2 Invasive Species Removal & Prevention Within the stream buffer, Scotch broom and Himalayan blackberry are interspersed within the open area. Himalayan blackberry and Scotch broom are invasive shrubs that threaten the health and success of native plants. In addition to the enhancement recommendations described above, it is recommended that the Himalayan blackberry be removed from the stream buffer to avoid further invasion and allow native vegetation to persist more abundantly. This may be done either manually or with the use of heavy equipment. Herbicides should not be used due to the proximity to the stream. The Bradley Method is one common approach to manually removing invasive species (Fuller and Barbe, 1985). This approach consists of hand removal starting in areas of lesser weed infestation, and working in toward the worst stands. Invasive species such as Himalayan blackberry, Scotch broom, Canadian thistle, fireweed, reed canary grass, Japanese knotweed, and English Ivy may invade the buffer and mitigation zone. These species are stubborn competitors for light and nutrients and limit success of native plants. Invasive species should be removed from the buffer should they invade. Persistent cutting during the growing season is sufficient to offset the rhizomes of invasive species if they become a problem.

The information gathered will provide the following: 1) condition of reintroduced plant species; 2) the use of the site by wildlife species; 3) any disturbance caused by the development and its effect on the protected zone and associated aquatic habitat; 4) any occurrence of exotic species within the mitigation zone; 5) any corrective measures that may be deemed necessary to provide desired conditions. This monitoring will be in effect for the duration of three years. The information gathered will be provided in an annual report and submitted to the Director of Mason County Department of Community Development. 8.0 SUMMARY This report addresses the effects of the establishment of a SFR and access road, occupying a total building footprint of 1642 square feet within the regulated buffer of a Type 3 stream. Best Management Practices are recommended to insure no negative impacts to the stream. Mitigation recommendations include native plant enhancement of 4500 square feet of open area in proximity to the stream, and invasive species removal within the entire stream buffer within the lot. No impacts to water quality or stream habitat are predicted. Mitigation Measures, and Best Management Practices, have been identified to avoid, minimize, and mitigate for impacts associated with proposed construction.
