We do intend, at the time of a building permit application, to submit a geologist's report specific to our final building plans. Also as a part of that permit application we expect to have an evaluation of the septic system done, again in terms of our specific use proposal Iz the meantime, %AA= expect this will suffice for establishing the new reserve area for the existing septic system,which was installed and had final approval in 1993. We look forward to completion of our boundary lot adjustment.Thank you for your patience. Sincerely, s (61 74/444-a-kp.

Garrison,PhD,LG �. 6 Washington State Licensed Geologist#2546 - Opinion Letter Regarding Septic System Use �OFFRFY Subject: H. OAR 1281 Rhododendron Drive—Tract 5 Dabob Cove Jefferson County, Washington This memorandum presents my professional opinions regarding the use of an existing sanitary septic system installed within a 4.75 acre parcel at 1281 Rhododendron Drive (Tract 5) on the east shore of Dabob Cove in Jefferson County, Washington (Subject Site). The issue of concern regarding use of the system is the potential to artificially exacerbate the natural susceptibility of the area to landslide events. Jefferson County has reportedly requested that the proposed use of the system be studied with respect to its potential impact on the area. 1.0 REPORT REVIEW The opinions herein are based upon review of several reports provided by the Subject Site owners: Geotechnical Slope Evaluation, Beach Drive-Dabob Cove Properly Access Road, Jefferson County, Washington.Prepared by Myers Biodynamics,Inc.

Prepared by Stratum Group,April 28, 2004. 1110 Dr.Geoffrey Garrison,PhD,L �° Page 3 of 3 Opinion Letter 1281 Rhododendron Drive rt Jefferson County, Washington ' `ii.; ,: • 5.0 REASONABLE WORST CASE SCENARIO A reasonable worst case scenario would consider the septic system operating at maximum capacity of 240 gpd,which is a conservative scenario because this rate is designed for a 2-bedroom house. Over an area of acre, 240 gpd is equivalent to 0.04 inches of rain, or approximately 10% of the average rain that falls on the area during the wettest part of the year, when landslide risks are greatest. In fact, the water infiltration rate from the septic system is less natural variability in rainfall for the area. That is, operating the septic system at maximum capacity during the wettest part of the year should not add a statistically significant amount of water to the subsurface as compared to the water it currently receives from rainfall. Furthermore, historic landslide events have occurred in the area of the Subject Site during major decadal-scale rainfall events such as the rains of January/February 1999. In these events, landslides were triggered by inches of rain falling per day for multiple days. The volume of water capable of being infiltrated by the Subject Site's septic system is less than two orders of magnitude (e.g., 100x) smaller than the rainfall in those events and thus not capable of creating a comparable impact,that is,a landslide. 6.0 CONCLUSIONS AND RECOMMENDATIONS If used as intended, the septic system located at the Subject Site should not significantly increase the natural risk of landslide occurrence for either the Subject Site or the surrounding area. Even under a reasonable worst case scenario, the rate of water infiltration allowed by the system design is not significant when compared to naturally occurring infiltration. Furthermore,the reasonable worst case scenario is conservative in that the system is not intended to be used during the wet season. The dwelling is only intended to be used between April and October,months when rainfall is approximately 10%to 50%as great as the wettest months on the year(December-February). Landslide events occur in the area of the Subject Site due to significant decadal-scale regional rainfall events such as occurred in January and February of 1999.The size of the septic system at the Subject Site does not appear to approach the scale of such events and is thus not considered any greater a landslide risk than the natural environment. r N C Z rn rn rn rnrnz,Irnp O rnmr A pU • z �; _ O� 0 _n n H/-V - 2 m _ �. rn ...., ,... v, Ti' A, '9y . 4;44 ALA,Cir.'-1 / �`` �'111• +� !, _ C��.=fir.\p'®1 • -1_ lilt,%•,.

Where the question calls for depiction on a site map, the applicant may choose to either incorporate the elements into the general plot plan for the Master Land Use Application or to submit a separate stormwater site plan map. Project Overview 1. Describe the proposed developed conditions of the site. Indicate position and relative size of proposed improvements on the site map. 120 SF shed with minimal plumbing and 700 SF unheated yurt for recreational storage.Level pads for new structures will be created within existing cleared areas. Site is 4.9G acres and approx 230' X 1087'.Existing clearing is approx .40 acres. Structures will be-580'from ordinary high water mark. Parking/driveway area will be gravel,approx 1000 SF. Site will have gravel footpaths and timber step areas of approx 820 SF. Bluff edges will have extensive native planting buffers. Existing Conditions Summary 2. Describe the existing topography. Indicate contours on the site map. Existing cleared area, in the south central portion of the parcel,slopes about G degrees NNW and is truncated by a steep bluff to bay. Bluff height is-295'. North of the cleared area is an approx 40 degree slope down to Beach Drive. Parcel to Southwest is a valley which slopes to bay at about 25 degrees.. Southeast is ridge above cleared area. Access is via Rhododendron Drive which terminates at southern property line,at existing cleared area. 3. Describe the existing vegetation. Indicate native vegetation areas on the site map. Cleared area is covered with grasses that presumably took over after septic system was installed in 1993. Except for this area the parcel is completely forested. Trees include maple,alder,fir.cedar and madrone.Shrubs are evergreen huckleberry,holly, oregon grape,ocean spray,salal, ferns and rhododendrons. Some small slopes and bluff edges have been recently planted with native shrubs. 4. Describe the existing soils. Indicate soil type on the site map. Soils include gravel.sand.silt and clay.Grey clay with minnr pebbles blanket the upper pnrtians._underlain by a thickhrown stratified sand unit.A pre-Fraser Glacial drift with an unsorted mix of clay,sand and gravel are beneath the sand unit.The lower slopes along the shoreline are underlain by a mix of soils from the slopes above. In the existing lower cleared area,septic system test pits indicate very fine sandy loam. 5. Describe the existing site hydrology (i.e., drainage; behavior of water on the site—above, below, and on the ground). Indicate existing stormwater drainage to and from the site on the site map. Depict separate drainage basins on the site map, if applicable, and indicate acreage of each. The site slopes to the north,south and east down to the water. Most stormwater runs on undisturbed forested flowpaths to the bay. One of the upper level areas drains down an existing ditch on the east side of Rhododendron Drive. - Generally the site is dry and well drained.During periods of heavy or persistent rainfall,for example the winter^fr._.��?��R there is comp minim^I ct^nding ^tP on the more level areas of clay.Those areas drain and become dry in several days at most. APPROVED 6. Describe any excess levels of noise generated by the proposed use or activity: STO-RMWATER PLAN The work proposed ' . ir, ittle hea' equipment;noise generated will be normal or below normal I;vels.

Describe significant geographic features and critical areas (i.e., environmentally sensitive areas such as wetlands, streams, steep slopes, etc.)on the site. Indicate location on the site map. The western property line is on Dabob Bay,The land slopes steeply up from the beach to a bluff approximately 300'above the water. There is a relatively level area of about.40 acres,which was cleared many years ago.The property is basically the southern edge of an ancient landslide scarp. Except for the clearing and some extremely steep scarp faces,the entire 4.96 acre parcel is forested. 8. Describe the general vicinity of the site, including adjacent land uses and structures, utilities, roads, and sensitive/critical areas (streams,wetlands, lakes, steep slopes, etc.). The site is located in Dabob Cove,a development of rural residential properties with single family homes and cabins.There are no structures on the parcels immediately north and south of this one. Most of the development is mapped as having steep slopes and landslide risk. Dabob Cove is serviced with underground electricity,a community well/water system and gravel roads.Rhododendron Drive is a gravel access road that begins at Coyle Road and terminates at the southern property line of this parcel. Permanent Stormwater Control Plan This portion of the Stormwater Site Plan consists of the selection and installation of the appropriate stormwater control BMPs and facilities to remain in place after construction of the project is completed. "Medium" size projects are required to have the totals calculated of all impervious surfaces, pollution-generating impervious surfaces, and pollution-generating pervious surfaces to verify that the thresholds for treatment facilities and flow control facilities are not exceeded. g. Describe the developed site hydrology, as proposed. Indicate whether stormwater will be fully dispersed (i.e., per BMP T5.30 in the Manual) or, if not, what types of stormwater flow control will be utilized for the site or specific threshold discharge areas within the site. Locate these facilities on the site plan and differentiate proposed facilities from existing facilities. Stormwater will be fully dispersed per BMP T5.30.Cleared and/or developed areas are 17500 SF,or 8%of entire site.92%of site is maintained in native and forested condition. Proposal is for less than!ODD sf of impervious surfaces,or less than.5%(one-half percent)of the site. Roof runoff will be handled with dispersion trenches. 10. If the project requires the use of stormwater treatment facilities, describe the types of stormwater treatment facilities proposed for use on the site. Locate these facilities on the site plan and differentiate proposed facilities from existing facilities. [This is normally for"large" projects or projects that involve the potential for dispersion of contaminants.] Our proposal does not include stormwater treatment facilities, 11. Describe the performance goals and standards applicable to the project. Our entire design approach has been to impact this sensitive site in as positive a way as possible.Our construction is lightweight with a minimal footprint. Our intention is to maintain as natural a runoff pattern as practical,while diverting stormwater away from steep bluffs. Steep bluffs will be further protected by native planting buffers near the edges. 12. Describe the flow control system. Stormwater will be fully dispersed on the site. 17- 'C 1177 ) a, stormwater site plan template.doc—rev.10/12/2003 6 • • 13. Describe the water quality system. Dispersion trenches will be gravel filled,wrapped in filter fabric and top protected with fill and/or larger rock.Native plantings on all slopes will provide erosion control. 14. Describe the conveyance system analysis and design. Design is simply collection trenches at the yurt drip line,and at shed roof downspots,running via drainage trenches to dispersion trenches and/or to forested flowpaths. 15. Describe the source of fill material, physical characteristics of fill material, and deposition of excess material. No fill will be required.Any excess material to be removed via truck by dirtwork contractor,most probably to his other dirtwork projects within this development. 16. Proposed methods of placement and compaction consistent with the applicable standards on Appendix Chapter 33 of the Uniform Building Code. Foundation piers will be placed on undisturbed earth,with adjacent fill to be placed and compacted by hand,in small lifts. Driveway and parking area gravels will be placed by truck and hand roller compacted. 17. Describe the proposed surfacing material. 3/4"basalt rock from Shine Pit. 18. Describe methods for restoration of the site. Primarily,construction is being kept to minimum,using very light construction.we do not anticipate any restoration will be required.No roads or driveways are proposed,due to the steepness of most of the property.The existing road ends at the gravel parking area. Foundation will be concrete piers,excavated and placed by hand. Trenches for utilites and drainage will be done by the smallest excavator possible. All disturbed ares will be replanted with native plants, covered with mulch tor erosion control,or planted with clover. 19. An Operation and Maintenance Manual is required for each flow control and treatment facility. [This is normally required for "large" projects only and only those for which facilities are required to control flow or treat runoff.] If included, list the Manuals here. N/A 20. List here and include any special reports or studies conducted to prepare the Stormwater Site Plan. Geotechnical Report from Stratum Group,October I,2007 21. List other necessary permits and approvals as required by other regulatory agencies. If those permits or approvals include conditions that affect the drainage plan or contain more restrictive drainage-related requirements, describe those conditions or restrictions here. Septic permit#SEP-91-00374 installed and finalled in 1993.
