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. This project involves a single family residence with an access driveway. Total impervious foot print including home and drive way will be 2,450 square feet. The project includes septic and pump tanks which tie to a drain field. The building location has been chosen to ensure a 95-foot setback from the top of bluff. Existing Conditions Summary 2. Describe the existing topography. Indicate contours on the site map. The official building envelope is a very gentle sloping area as indicated on the accompanying site plan. It is bordered on the southeast by a buffer area between the building area and a landslide hazard area. The proposed home will be located 95 feet from the landslide hazard area. The landslide hazard area is a landslide complex that slopes down to a steep shoreline bluff slope above Dabob Bay.The slide area is tree covered with mature second growth trees.Areas of recent movement have bare soils and some trees have fallen over. The upland area above the slide between McDonald Road is partially tree covered and partially brush covered with few mature trees. McDonald Road traverses across the upland portion of the property.The area upslope from McDonald Road is forested with second growth to third growth trees and thick brush understory. A ditch along the upslope side of McDonald Road intercepts shallow perched ground water and directs the water onto the subject property. This water flows across the northeast side of the property and has been flowing onto the landslide area and likely contributed to recent slope movement in January 2010. 3. Describe the existing vegetation. Indicate native vegetation areas on the site map. Trees on site are a mix of second growth to third growth trees with Douglas fir, big leaf maple and red alder being the dominant species. Ground cover is comprised of primarily with sword fern salal and other brush. 4. Describe the existing soils. Indicate soil type on the site map. The upland area is underlain by soils derived from glacial till and ice wasting/ice contact gravel soils.The landslide complex area is underlain by very compact sand and gravel and silt units. The shoreline bluff is ubderlain by compact massive silt with some very compact sand and gravel. Soil under the proposed building site area consist of thin sand and gravel underlain by compact silt sand gravel till. The thickness of the permeable upper soil varies significantly on the upland area but is generally a few feet thick in the building area • • 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 upland area is generally underlain by glacial till which extend up the gentle slopes to the northwest off of the property. Perched shallow groundwater seasonally develops in these areas. The hydrology has been somewhat altered by the presence of McDonald Road as the ditch on the up slope side of the road intercepts seasonal perched shallow groundwater over a distance of approximately 400 feet and directs that intercepted groundwater into a culvert which discharges onto the subject property.This ditch water has in the past generally flowed toward the east to a low area on the landslide complex away from the proposed building area. However due to vegetation and sediment accumulation water was sheet flowing over a larger area and getting concentrated on the head wall area of the landslide complex and likely played a role in slope movement in January 2010. Minor deep perched water as well as any other perched water within the slide complex seeps out onto the top of the very steep shoreline bluff and flows over this very hard material top the beach area below.A small seasonal intermittent stream flows from across the northeast corner of the property flowing from the southeast to the northwest. The stream continues towards the bluff face where it daylights on the bluff face as a series of small cascades across the bedrock to the beach below. Downward drainage of surface water into the soil ultimately becomes somewhat impeded by the underlying till where the till is present and after infiltrating deeper past the till perches on the very hard silt. 6. Describe any excess levels of noise generated by the proposed use or activity: Short-term construction related noise only. No long term noise sources. 7. 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 property is bordered on the southeast by a steep slope down to Dabob Bay. This slope is a landslide hazard area. 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 project site is located on the southeast end of the Bolton Peninsula on McDonald Road. Adjacent land use is rural residential and forestry. Electric and phone utilities area available along McDonald Road. A steep shoreline bluff is located to the southeast.The upper portion of this bluff is a landslide complex with evidence o1 slope movement both recent and many years old. 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. Site hydrology has been altered in the past by the construction of McDonald Road and the interception of perched ground water by the upslope ditch on McDonald Road. This water is currently discharged onto the subject property such that periodic concentrated groundwater develops on a portion of the site. This water will be rerouted to an area that will have minimal to no impact on the land slide complex. All stormwater generated on the site as well as foundation drainage and a cutoff drain to assist in drainage around the building site will be routed via ditch and tightline to a location where introduction of water will have a minimal impact on the landslide complex. The cleared area for development will be well under 65% of the site. The area not cleared will be left primarily as tree cover with native brush. The property is in a rural single-family residential and forestry area and well under 10% of the area will be covered with impervious surfaces. 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.] The area of pollution-generating impervious surfaces (the driveway) is less than the threshold area of 5,000 sf. No treatment is required. • • 11. Describe the performance goals and standards applicable to the project. Stormwater and existing drainage from County road will be routed to an area will no erosion or increase risk of slope failure will result from routing of stormwater. 12. Describe the flow control system. The site does not require flow control. 13. Describe the water quality system. Water from the driveway will sheet flow off of the driveway and infiltrate into the ground. Some of this infiltrated water will be intercepted by the cut off drainage system. 14. Describe the conveyance system analysis and design. Design is simply a 4-inch pipe conveying stormwater to an infiltration area where impacts to the landslide hazard is minimal. 15. Describe the source of fill material, physical characteristics of fill material, and deposition of excess material. No fill material will be required except for the necessary drainage fill gravel and sand for the foundation. Excavated materials will be relocated onsite away from the steep shoreline slope and away from the slope on the southeast side of the property. 16. Proposed methods of placement and compaction consistent with the applicable standards on Appendix Chapter 33 of the Uniform Building Code. A compactor will be used as necessary to achieve 90%of maximum density for foundation and driveway support. 17. Describe the proposed surfacing material. Grass with gravel driveway. 18. Describe methods for restoration of the site. Any disturbed sites will be restored with native plants or grass. 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. Assessment of Landslide report. 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. CONSTRUCTION STORMWATER POLLUTION PREVENTION PLAN (SWPPP) The Construction SWPPP addresses sediment and erosion control during construction. The BMPs indicated by the applicant in• template that follows must be listalled on the ground during all construction phases of the project. The proponent is responsible for preventing sediment and erosion impacts to environmentally sensitive areas and off-site areas. Consult the Construction Stormwater Pollution Prevention (SWPP) Best Management Practices (BMPs) Packet for guidance, particularly with rural residential development. SECTION I - CONSTRUCTION SWPPP NARRATIVE 1. Construction Stormwater Pollution Plan Elements. Describe how each of the Construction SWPPP elements has been or will be addressed. Identify the type and location of BMPs used to satisfy the required element. If an element is not applicable to the proposal, justify in writing. Descriptions of the 12 Elements are found at section 2.5.2 of the Manual (beginning on page 2-15). 12 Required Elements—Construction SWPPP 1. Mark Clearing Limits. The building-affected portion of the parcel is clearly marked. Silt fences will be maintained down slope of the construction area to ensure that sediment does not flow toward the shoreline. 2. Establish Construction Access. A stabilized construction entrance will be maintained between McDonald Road and the building area. It will be a minimum 10 feet of width and will be gravel covered. 3. Control Flow Rates. Native vegetation will be maintained as a wide vegetated strip between the proposed home site and the top of the shoreline bluff).Given the general topography of this parcel and the wide native vegetated area to the southeast of the proposed building area, it is expected that sediment traps will not likely be required. 4. Install Sediment Controls. Silt fences will be installed prior to site grading. 5. Stabilize Soils. Stockpiled soil and areas exposed for short periods (less than two days between October 1 and April 30 and less than one week between May 1 and September 30) may be stabilized using appropriate measures from the following BMPs: nets and blankets (C 122), plastic covering (C 123), and dust control (C 140).Stockpiled soil and areas exposed for short periods(less than two days between October 1 and April 30 and less than one week between May 1 and September 30 may be stabilized using appropriate measures from the following: mulch,straw or nets and blankets. 6. Protect Slopes. Silt fencing will be installed approximately 80 feet or more between the steep slope and the proposed building area and native vegetation within this area will be left in place over a distance of at least 30 feet. No clearing or construction work will take place within 50 feet of the steep slope. Drainage will be directed to the northeast and routed into a drain line to an area of the slope that will minimize slope stability problems. 7. Protect Drain Inlets. The drain inlet pipe that will route water to the base of the upper steep slope to the east will have a filter fabric place over it during site clearing and grading and construction. 8. Stabilize Channels and Outlets. The existing drainage from McDonald Road that is discharges to the property has been stabilized by clearing the low ditch it traveled in and deepening and berming the sides of the ditch to maintain flow within the ditch so that water will continue to flow to the safest place on the bluff slopersus onto unstable portions of the Iandslid•mplex.Water will be routed down the upper steep slope to the base of the steep slope via a tightline pipe so that erosion of the slope will be eliminated as the current road ditch water has been causing erosion.The outfall of the tightline will discharge onto a low slope area through an enrrgy dispersion T surrounded by quarry spall or equivalent rocks. 9. Control Pollutants. No vehicle maintenance will be performed and construction debris will be safely stored. 10. Control De-Watering (the act of pumping groundwater or stormwater away from an active construction site). No construction dewatering will be conducted. 11. Maintain Best Management Practices (BMPs). BMPs will be maintained.All temporary and permanent BMPs shall be mainatained, repaired and enhanced as necessary to assure continued performance of their intended functions.All BMPs should be inspected at a minimum on a weekly basis, during and immediately following significant storm events (any storm exceeding 0.5 inches within 24 hours or 2.0 inches of rainfall within 7 days). 12. Manage the Project. All construction work shall follow the above described actions. If circumstances arise that require additional BMPs beyond those listed, it is the owner/contractor's responsibility to implement those BMPs. The owner/contractor should inspect the site for BMP implementation on at least a weekly basis and more frequently during significant rainfall events. 2. Adjacent Areas. a. Description of the adjacent areas that may be affected by site disturbance (e.g., streams, lakes, wetlands, residential areas, roads). A public road ditch discharges intercepted perched groundwater onto the subject property. Water from this discharge has flowed on and infiltrated into the ground just above a potentially unstable landslide complex and has flown over a steep slope in a manner that has caused erosion. This discharge from the county road will be better controlled as described above and stormwater from the roof and site drainage will be directed into this repaired drain system. The water flowing through this system may be affected by site disturbance. BMPs to prevent sediment from the construction area from entering the drain system will be maintained. The shoreline bluff will not be effected by the clearing the proposed development as storm water readily will be directed towards the east to the above described drainage system so that no water will be directed onto the portion of the landslide complex that could increase slope instability. b. Description of the downstream drainage path leading from the site to the receiving body of water(minimum distance of 400 yards). Stormwater will be infiltrated into the repaired drainage system that discharges from the County road ditch system onto the subject property. This water will along with the larger volume of water in the ditch system from the County road will flow through a tightline pipe to the base of the steep upper slope. From there some of the water will infiltrate into the ground. The water reaches the top of a very hard compact silt/clay unit at the top of the shoreline bluff and flows down the slope to the base of the steep shoreline bluff where it infiltrates into loose soil above the beach area along the shore of Dabob Bay. 3. Environmentally Sensitive Areas. a. Description of environmentally sensitive areas that are on or adjacent to the site. The property is bordered on the southeast by a steep shoreline slope down to Dabob Bay. The upper portion of this slope is a landslide hazard area. b. Descrption of special requirements for working in or near environmentally sensitive areas. All work will be within the limits of the clearing area.Any run off will be directed to the east so no drainage will be directed onto the sensitive part of the landslide complex. n Rio - I 1 . STRATUM GROUP PO Box 2546, Bellingham, WA 98227 Phone(360)714-9409 July 13, 2010 Laura and Chuck Cooper 691 Raccoon Road Oakland, OR 97462 Re: Stormwater Drainage Discharge Location Parcel 701324007, McDonald Road Quilcene, Washington Dear Mr. and Ms Cooper: It is my understanding that the drainage discharge proposed for your property as previously drawn in the storm water plan submitted to Jefferson County is within 200 feet of the ordinary high water mark. If left at that location, the County has indicated that a shoreline permit review would be required. It is acceptable to move the discharge point indicated back as indicated on the attached revised Stormwater Site Plan Sketch as drainage water would still be delivered to the same location. Although the proposed stormwater drainage discharge point is outside of the shoreline jurisdictional boundary of 200 feet from the ordinary high water mark, the drainage system is still consistent with Jefferson County's Shoreline Management Master Program. JCC 18.25.440 (3)(f) states "Road drainage shall be designed to control the dispersal of surface runoff from roads and exposed soils in order to minimize turbid water from draining into waterways", and JCC 18.25.440 (3)(s) states "All roads and drainage systems shall be maintained to prevent erosion and/or water quality degradation". At the present time drainage from McDonald Road intercepts perched groundwater in a ditch and directs that water onto the subject property. This water has generally flowed to the point of the proposed drainage discharge in the past but lack of maintenance over the years led to water flowing into areas that reduced stability on portions of the landslide complex on the subject property. The proposed routing of the drainage is to maintain the existing drainage pattern established by the County road drainage system and will minimize turbid water and prevent erosion. JCC 18.25.410 (3)(i) states that"Residential development in shoreline areas should be designed to preserve natural drainage courses, aquifer recharge areas, and similar ecologically sensitive areas."the proposed routing of drainage water maintains the current drainage that has been in place on the site via drainage from the County road and directs water to the best possible location for drainage water in regards to bluff stability and land slide stability. 0 • Stratum Group appreciates the opportunity to be of service to you.
