Site Plan 03/01/2003 06: 39 3603529914 THE COOT COMPANY PAGE 03 INTRODUCTION This Habitat Management Plan has been prepared to address the placement of a small manufactured home on a lot located within Mason County. The new home will be situated within the buffer from a nearby Type 1 stream. The existing site is already well developed with a compacted gravel pad, a large garage/work shed, and all utilities (water, power, septic). The proposed placement of the manufactured home will present minimal change in the use of the property than currently occurs. However, concerns about stormwater runoff'potentially impacting stream flows should be mitigated with some type of detention system. METHODS Site Iaspeetion Site review was performed on 5 February 2003. The entire property was reviewed for stream and wetland conditions. Stream Definition Streams were typed pursuant to WAC 222-16-030 within the Washington Forest Practices Act prepared by the Department of Natural Resources. PF-ESTON HABITAT MANAGEMENT PLAN THE COOT COMPANY - t - 03/01/2003 06: 39 3603529914 THE COOT COMPANY PAGE 04 RESULT'S EXISTING CONDITIONS Developed Lots This property is a small lot within an older development community of similar properties_ The lot adjacent to the north is fully developed with an existing home site. The lot adjacent to the south is currently undeveloped, and retains a mostly forested condition. Z_- T C--"- �a Existing Site Improvements The lot already contains a full compliment of site improvements. A compacted gravel pad has been graded into the landscape creating a well-defined footprint of"useable" area. Water and power are established, and a working septic system is already in place. A large, 2-bay garage/work shop has also been constructed. Retained Forested Habitat Area outside of the compacted gravel pad is nearly all retained native conifer forest J habitat. Original ground contours are generally intact, and ground, shrub and tree canopies are fully established. Cranberry Creek Cranberry Creek, a Type 1 stre occurs along the western boundary of the lot. A small dirt path leads down to the creek from e eve ope area to a small shore me clearing. Shorelines within.this portion of the creek contain a good border of mature forested habitat, with a partially closed tree canopy over the water. Developed portions of lots in this vicinity do not extend to the stream edge. PROPOSED USE Construct Small Cabin The property owners are proposing to place a small manufactured home within a leveled portion of the existing gravel pad. _ PRESTON HABITAT MANAQEMENT PLAN THE COOT COMPANY -2- 03/01/2003 06: 39 3603529914 THE COOT COPIPAHY PAGE 05 IMPACT ASSESSMENT Existing Building Pad Proposed placement of the manufactured home will be completely confined to the existing limits of the compacted gravel pad that occurs. No vegetation of any kind will be disturbed to place the new home. Cranberry Creek High Flow Sensitivity The development of home sites bordering Cranberry Creek within this general vicinity have likely caused an increase in the speed with which stormwater runoff enters the stream. Most sites are positioned well above the channel with developed areas that slope towards it. This site, in particular, already has the existing garage runoff directed to downspouts that appear to daylight on the stream slope just west of the developed gravel pad. Although native forest left along the sides of the creek provide good habitat for protection, especially shading, buffering against stormwater runoff from developed areas is minimal. Excessive stormwater runoff may cause excessive peak flows within the system that could be detrimental to anadromous fish. RECOMMENDATIONS Site New Home Where Proposed The proposed new homesite is the best place to site this structure. Placement anywhere else would require additional clearing and grading. Create Stormwater Detention Stormwater runoff off from the existing garage and the proposed new home should be directed into small detention ponds excavated within the gravel pad. These ponds would not have to be engineered, but could just be built to the maximum size possible that fits into existing site conditions. The ponds should be highly permeable, given the gravel conditions, and should infiltrate quickly. In addition,no piping or channelization of any stormwater runoff should occur that directs flows to the edge of the developed gravel pad. No Vegetation Removal No vegetation of any kind should be removed or cut between the developed gravel pad and the Cranberry Creek channel. This restriction should especially prohibit the removal of any woody debris from the strearn channel, including trees that may topple over in the course of channel migration, or pile up during flood flows. No Stream Bank"Stabilization" No efforts to "stabilize" the existing stream bank should be allowed. Any erosion that may occur should be regarded as natural stream channel migration. No Yard Waste Disposal Dumping of yard waste or any other organic debris on the slope west of the developed area that drops to the stream channel should not be allowed.

Attn. Michelle Stevie 2952 SE Old Olympic Hwy. Shelton, WA. 98584 RE: Habitat Management Plan for the Preston Property Dear Michelle, The enclosed Habitat Management Plan(HMP)has been provided by a property owner who is applying for a Mason County Resource Ordinance Variance. This ordinance requires buffers and building setbacks from areas such as streams, lakes and ponds that support fish and/or wildlife habitat. The applicant is proposing to locate a small manufactured home within the buffer from a nearby Type I stream, Cranberry Creek. Currently, on the site is a large gravel/work shed, compacted gravel pad and utilities. The edge of the streambank of Cranberry Creek is approximately 50' from the proposed placement of the home. Please review the enclosed HMP and let me know if you have comments, question, or concerns about this plan. I can adopt your comments as conditions into any approval the County may grant. I have included my e-mail address if you find this method of correspondence more convenient. Our ordinance allows for a 28-day comment period. Closing date for comments is May 30, 2003.
