The site is found in the SE '/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 single-family residence (SFR) occupying 2000 square feet, a portion of the septic occupying 500 square foot, and a portion of the proposed access road occupying 600 square feet within the section of the parcel encompassed by the regulated buffer of a type S stream (Cranberry Creek). The type S stream requires a 150-foot buffer with an additional 15-foot building setback, occupying approximately two-thirds of the entire parcel. The septic requirements push the house west, 80 feet from the stream at the nearest point. Therefore, a variance is necessary to complete the proposed project. A portion of the proposed septic and driveway will occupy the only portion of the property that is not encompassed by the stream buffer. The access driveway will enter the property via East Olde Lyme Road. 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, septic and access within the Type S 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, septic and access road within the Type S stream buffer. PROPERTY DESCRIPTION The ownership is comprised of a low gradient landscape (less than 10 percent) within the eastern three-quarters of the ownership, then transitions to a steep slope down toward Cranberry Creek which drains southerly, paralleling the western property boundary. The vegetation theme for subject parcel consists of Douglas Fir with a shrub layer dominated by salal, Oregon grape, evergreen huckleberry and sword fern. The parcel is bordered to the west by Cranberry Creek, to the east by East Olde Lyme Road, and to the north and PO Box 2854, Belfair,WA 98528 cell:360-620-0618, Office: 360-372-2421 e-mail: boad40@peoplepc.com • Parks Habitat Management Plan TWC No.07W331 October,2007 Page No.2 south by residential parcels of similar size and shape. No other regulated waters were found within the subject parcel. This stream has been identified as a Type S Stream because it is a fishbearing stream that is identified by the Department of Natural Resources as a Shoreline of the State. Type S streams in Mason County require 150 feet of undisturbed buffer with an additional 15-foot building setback. The inventoried stream is located approximately 235-feet west of East Old Lyme Road. Cranberry Creek is identified as WRIA number 140051 in the Shelton Basin. The stream drains southerly to eventually drain into the northern end of Oakland Bay. A`Lr�t Ig .s 1 ti L a °Y Figure 1. Cranberry Creek APPLICABLE SETBACKS The project site is within the jurisdiction of Mason County. Ordinance 17.01.040 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 S Stream 150, 15' Parks Habitat Management Plan TWC No.07W331 October,2007 Page No.3 DESCRIPTION OF HABITAT AND SPECIES 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. Although the type S 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. The Cranberry Creek watershed has been recently excluded from the NOAA Fisheries Northwest Region Critical Habitat Designations for West Coast Salmon and Steelhead in Washington. Given the absence of critical habitat,this project is not expected to impact Puget Sound Chinook. Puget Sound Steelhead(Oncorhynchus mykiss)-Threatened Listed as Threatened since May 2007, Puget Sound Stealhead spawn in several streams throughout Puget Sound. Spawning usually occurs in moderate to steep gradient sections of streams, usually in heads of riffles or the tails of pools where hydraulic conditions are conducive to intragravel flow. Side channels and the anterior portions of islands are also used. Spawn timing for summer steelhead runs typically ranges from mid May through October while winter run steelhead are present from December through May. Adequate cover from predation, water temperature, and spawning gravel are important factors for instream habitat, while little is currently known about specific marine habitat requirements. Cranberry Creek may support suitable steelhead habitat although documentation of their presence is not available. The recommendations provided in this report are intended to protect water quality and aquatic habitat important to all native fish species including steelhead. 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. The nearest population of bull trout occurs as three subpopulations in the Skokomish Basin. No bull trout habitat is in proximity to or will be affected by the proposed project. 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. There are no documented Bald Eagle nesting sites in the vicinity of the project area. The proposed project entails the removal of Douglas fir trees of similar age and size within an area of 3100 square feet within the stream buffer. The trees to be removed do not contain Parks Habitat Management Plan TWC No.07W331 October,2007 Page No.4 nesting and roosting features important for the Bald Eagle, such as exposed lateral limbs or dead tops. Mitigation recommendations entail the preservation and enhancement of habitat components within the portion of the stream buffer outside of the development zone. Given there are no documented Bald Eagle nesting sites in the vicinity of the project area,this project will have no adverse impacts on bald eagles. 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. Northern Spotted Owl(Strix occidentalis caurina)-Threatened Spotted owls require a large amount of land for their nesting and hunting grounds; pairs may occupy up to 58 sq. km. They are territorial and do not migrate, but they may shift their ranges slightly in response to seasonal changes Suitable spotted owl habitat includes trees relatively large in diameter, multi-layered forest canopy with a moderate to high canopy closure in overstory, midstory, and understory, large, tall, live trees with cavities, broken tops, mistletoe, or platforms of branches capable of holding accumulated organic matter suitable for use as a nest. Dead standing trees and fallen decayed trees supporting abundant populations of prey species are critical to spotted owl populations. Currently there are no spotted owl nesting sites documented in proximity to the project site. There are no indicators of current utilization within the parcel. Mitigation measures such as preservation of a riparian forested portion of the parcel and installation of nurse logs are recommended to preserve and enhance habitat components important to prey species often foraged on by Spotted Owl. ANALYSIS OF EFFECTS The project lies within the regulated buffer of a Type S stream. Project scale in the protected area is as follows: Development Type Habitat Type Project scale within buffer SFR Type S Stream Buffer 2000 sq. ft. Parks Habitat Management Plan TWC No.07W331 October,2007 Page No.5 Septic Type S Stream Buffer 500 sq. ft. Access Road Type S Stream Buffer 600 sq. ft. Total Type S Stream Buffer 3100 sq. ft. Vegetation Disturbance The SFR, access and septic are located in a portion of the ownership that contains primarily Douglas fir (Pseudotsuga menziesii, FACLJ) of similar size and age with an associated understory comprised of salal, swordfern, Oregon grape and evergreen huckleberry. The trees are approximately 12 inches Diameter at Breast Height (DBH) on average. The total area of native vegetation to be removed from the stream buffer occupies approximately 3100 square feet. The remainder of the vegetation between the development zone and th&ll be preserved from any future disturbances. A split rail fence is recommended in the Mitigation Measures section of this report, to be installed between the development zone and the remaining riparian area, to ensure that no future vegetation disturbance will take place within the undisturbed buffer. 1� i I' Figure 2. Vegetation theme throughout entire parcel,and approximate location of proposed SFR. Designated Critical Habitat for Salmonids The Cranberry Creek watershed has been recently excluded from the NOAA Fisheries Northwest Region Critical Habitat Designations for West Coast Salmon and Steelhead in Washington. 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 Parks Habitat Management Plan TWC No.07W331 October,2007 Page No.6 modify designated critical habitat. Actions described in this plan are not expected to jeopardize the continued existence of any listed species. 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 proposed project. 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 to avoid any adverse effects associated with sediment and turbidity during project implementation. Light and Glare The proposed project will result in an increase in light and glare commonly associated with residential construction and land use. The vegetative buffer to be preserved 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. MITIGATION MEASURES Preservation Mitigation The remainder of the Type S stream buffer outside of the proposed SFR, septic and access road, will be preserved and remain in tact. It is recommended that a split rail fence be installed 15-feet from the westernmost extent of the project zone to isolate and preserve the remaining portion of the stream buffer from any future disturbances. The location of the split rail fence is shown in Figure 2. Site Map. The split rail fence is recommended because of reasonable cost and easy installation. Other types of fencing may be used upon approval of the Mason County Planning Department. Parks Habitat Management Plan TWC No.07W331 October,2007 Page No.7 l is i Figure 3. Portion of parcel to be protected by installation of split rail fencing. Minimization Mitigation The proposed project minimizes impacts to the stream buffer by limiting the square footage of the building footprint of the SFR to 2000 square feet. The proposed SFR is i' located 80 cet from the stream at the nearest point, this is the furthest distance from the stream that the size and configuration of the lot will allow while meeting project objectives and septic requirements. 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(See diagram below). • 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. • Parks Habitat Management Plan TWC No.07W331 October,2W7 Page No.8 4' NIGH -ONSTRUCTION STEEL POST FENCE FWV / f� 10 R VAX SPACIIO N71H wYIE SUPPORT FENCE 6 R MM SPACNG MRNOUT RIW SUPPORT FENCE FILTER FABRIC PONDING HT.

RUNOFF 12T wi- ;'V 4 X9 CFlPZ6 Silt Fence Diagram Silt fence Installation The presence of exposed soil in proximity to regulated waters poses a risk of erosion and siltation during storm events. It is recommended that silt fencing be installed between the work areas and the stream to avoid siltation of waters. The silt fence should be inspected and repaired if necessary after each storm event. Sediment should be removed from the fence and deposited to an area that will not contribute to regulated waters. The fence can be removed once construction is complete and erodible soils are stabilized through a permanent erosion control feature such as grass seeding or woodchip placement. Enhancement Recommendations It is recommended that the trees greater than 4 inches DBH (Diameter at Breast Height) that are removed for the project be placed within the portion of the stream buffer that is outside of the project zone as nurse log habitat. The trees should be cut into eight-foot sections and randomly situated throughout the riparian corridor to mimic natural dispersion. Natural cavities and dens are provided by nurse logs, creating foraging and nesting areas for birds and mammals. Invasive Species Removal Invasive species such as Himalayan blackberry, reed canary grass, Japanese knotweed, and English Ivy may invade the stream buffer. These species are stubborn competitors for light and nutrients and limit success of native plants. Invasive species should be removed from the stream buffer, should they invade. Herbicides should not be used to Parks Habitat Management Plan TWC No.07W331 October,2007 Page No.9 achieve this due to the proximity to the stream. Persistent cutting during the growing season is sufficient to offset the rhizomes of invasive species if they become a problem. MONITORING Monitoring of the site will begin the first fall following project completion and maintained on a seasonal basis. The information gathered will provide the following: 1) determination of compliance with the mitigation recommendations in this report; 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 stream buffer; 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. SUMMARY This report addresses the effects of the establishment of a SFR, a portion of a septic, and a portion of an access road occupying an area of 3100 square feet within the regulated buffer of a Type S stream (Cranberry Creek). Septic requirements push the house west toward the stream,therefore, a variance is necessary for the proposed project. The SFR is proposed 80 feet from the stream at the nearest point. Mitigation recommendations include the installation of a split rail fence to preserve the portion of the stream buffer outside of the project zone, and enhancement of nurse log habitat within the stream buffer. Best Management Practices are recommended to insure no negative impacts to the stream. 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.
