MUST COLLECT AND DIVERT ALL SOURCES OF DRAINAGE AWAY FROM SEPTIC TANK, RESERVE & DRAINFIELD. MUST COMPLY WITH ALL PERMIT CONDITIONS, STATE AND LOCAL CODE. 5.) The application was reviewed by the Jefferson County Department of Community Development staff on August 29, 2007 for the potential presence of Environmentally Sensitive Areas (ESAs) under the provisions of the Unified Development Code (UDC). After an initial Geographic Information Systems mapping review and an investigative site inspection, the following ESAs were confirmed to be present on the subject property: SARPA aquifer recharge area. 6.) Aquifer Recharge Areas in Jefferson County are characterized by porous geological formations that allow percolation of the surface water into the soils and the underlying zone of saturation. Aquifers are geologic formations that contain sufficient saturated permeable material to yield significant quantities of water to wells and springs. Aquifers serve as the source of drinking water within most of the rural portions of Jefferson County. 7.) Susceptible Aquifer Recharge Areas are those with geologic and hydrologic conditions that promote rapid infiltration of recharge waters to groundwater aquifers. 8.) Critical Aquifer Recharge Areas are defined as Seawater Intrusion Areas, and Special Aquifer Recharge Protection Areas and the following land uses located within Susceptible Aquifer Recharge Areas (1)All Industrial Land Uses (2)All Commercial Uses (3)All Rural Residential Land Uses requiring a Discretionary Use or Conditional Use Permit (4)All Rural Residential Land Uses with nonconforming uses that would otherwise require a Discretionary Use or Conditional Use Permit (5) Unsewered Planned Rural Residential Developments (6) Unsewered residential development with gross densities greater than one unit per acre. All of the above listed uses shall be subject to the applicable requirements and standards of the Jefferson County Unified Development Code. 9.) Critical Aquifer Recharge Areas may require special protection measures to mitigate water quality degradation. The submitted proposal does not require additional aquifer protection measures. However, during construction the project shall follow the Best Management Practices (BMPs) and facility design standards as identified and defined in the Stormwater Management Manual for the Puget Sound Basin. 10.)

R 1 W. Property Owner: Robert&Mary Weidner Scope of Project: The project is a single-family residence that is located on a 12500 square foot parcel. The proposed single-family residence will be the primary structure on the site, with an attached garage. It is the owner's intent and responsibility to provide this plan and implementation thereof, for stormwater management on the subject site both during construction and thereafter, while in ownership of the property. STORMWATER SITE PLAN SUBMITTAL Project Overview 1. Describe the proposed developed conditions of the site. Indicate position and relative size of proposed improvements on the site map. The site is a 12500 square foot parcel. The proposed improvement consists of the placement of a one- story single-family residence of 3290 square feet, garage and porch, and the driveway and parking area serving the residence, constructed of concrete. The proposed impervious surface falls within the "Medium" project requirements under the Washington State Stormwater Management Mq al for Western Washington project with 3354 square feet of total impervious surface for this proposaV O S) Existing Conditions Summary \I" 4- 2.

STORM WATER PLAN The existing soils consist of the Clallam[CmCg series of well drained, sandy-loam soils. AUG 3 0 2007 Stormwat-r ; I 1% JEFFER oU Require° t .�I 1 SDIGN o E. DEEL PME T qb r • . 5. Describe the existing site hydrology (i.e., drainage; behavior of water on the site— above, below, and on the ground). Indicate existing storm water 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. This soil is described as well drained. Runoff is slow to medium, and the hazard of water erosion is slight to moderate 6. Describe any excess levels of noise generated by the proposed use or activity: The proposal is for a single-family residence with garage, which are the typical uses, associated to the subject area's properties. . 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. None. 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.). Adjacent properties consist of single-family residential uses. N. Andrews right-of-way is a paved[light bituminous treatment]road surface, which provides the traditional utility corridor. Permanent Storm water Control Plan This portion of the Stormwater Site Plan consists of the proponent's selection and installation of the appropriate storm water control BMP's 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. Please see Master Permit Application submittals for these calculations. 9. Describe the developed site hydrology, as proposed. Indicate whether storm water will be fully dispersed (i.e., per BMP 15.30 in the Manual) or, if not, what types of storm water 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. The construction of the residence will provide channeled roof flow via downspouts to direct flows to dry well. Road way surface grades will direct water to the downhill side of such roadways to achieve the same effect, where bio-filtration will take place of surface water. 10. If the project requires the use of storm water treatment facilities, describe the types of storm water 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.] No specialized storm water treatment is necessary for this project. 11. Describe the performance goals and standards applicable to the project. All storm water is managed on-site and is not anticipated to create erosion i rq Itst�/e mitigation. JUL 242007 2 gillItilo11111011D • • 12. Describe the flow control system. The construction of the residence will provide channeled roof flow via downspouts to direct flows to the owner's dry well. Road way surface grades will direct water to the owner's lot side of the driveway to achieve the same effect. Due to the soils, it is anticipated that none will migrate off-site. 13. Describe the water quality system. None is proposed or required of this proposal. 14. Describe the conveyance system analysis and design. None is proposed due to the low rainfall statistics of the area, and due also to the size of the property, and also due to the proposed "best management practices". 15. Describe the source of fill material; physical characteristics of fill material, and deposition of excess material. House foundation excavation material will be primarily re-deposited around subject residence, and back-graded to form a slope away from the residence. Approximately 1000 square feet of driveway and parking area is to be concrete. 16. Proposed methods of placement and compaction consistent with the applicable standards in the International Residential Code,2003 Edition. Heavy machinery use will provide primary spreading and compaction, normally with the bac p o small excavator. I RI1 ( a i ) 17. Describe the proposed surfacing material. JUL t4 ? Traditional landscaping with gravel, tree bark, and rock retaining wall. 18. Describe methods for restoration of the site. l[ff[liboupili:i None required, as site for residence does not require the removal of trees. The owner may choose to increase the number of existing trees with additional planting. 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. Not applicable for this proposal. 20. List here and include any special reports or studies conducted to prepare the Storm water Site Plan. Jefferson County SEP95-202 21.

The BMP's indicated by the applicant in the responses that follow are to be installed on the ground during all construction phases of the project. The proponent and official representative will be responsible for preventing sediment and erosion impacts to environmentally sensitive areas and off-site areas. The proponent and official representative will also consult the Construction Storm water Pollution Prevention (SWPP) Best Management Practices (BMP's) Packet for guidance SECTION I-CONSTRUCTION SWPPP NARRATIVE 1. Construction Storm water Pollution Plan Elements. This section describes how each of the Construction SWPPP elements has been or will be addressed. It identifies the type and location of BMP's used to satisfy the required elements. If an element is not applicable to the proposal,justification is provided. Twelve Required Elements- Construction SWPPP 1. Mark Clearing Limits. Minimize limit of land clearing to the residential, garage, utility and roadway locations only, and marking [flagging]equipment operation zones. 2. Establish Construction Access. Via the existing driveway, machinery will not require a formal construction access. Wash-down of vehicle tires on-site will further control such occurrence during wet days. Wash-down would take place only in designated areas where water retention and settling of suspended solids will occur. 3. Control Flow Rates. BMP C121 "Mulching" may be implemented to filter any and all downhill water flow, and thus stabilize the flow rate, but only if it is determined to be necessary. 4. Install Sediment Controls. While limiting the cleared area for construction, the applicant will install a silt fence to protect "downstream"areas below the construction site during construction per BMP C233. 5. Stabilize Soils. The applicant proposes to use BMP C121 "Mulching" to stabilize exposed soils that are subject to erosion, where applicable along the proposed roadway extension to the proposed new residence and parking area. 4 • • 6. Protect Slopes. The applicant proposes to use "surface roughening" BMP C130 and soil stabilization with BMP C121 " Mulching"at sloped areas with a ratio of 3:1 horizontal to vertical and greater during construction, and until new vegetative growth is established, where and when necessary. I R y wt ' ��l \Ur J�IT )) 7. Protect Drain Inlets. No drain inlets exist either on or off the subject site. JUL 2' 4 hill 8. Stabilize Channels and Outlets. IEH+) IINIAIINIWEI1 No temporary or permanent on-site channels or ditches exist or are to be created to control runoff However, since the proposal consists of a crawl-area grade that is below the finished grade outside of the foundation, in the event of water retention, a small channel would be created during construction to allow drainage of the foundation excavation which will likely require the use of BMP C209 and mulching BMP C121 until foundation backfill is completed. 9. Control Pollutants. No major vehicle or machinery maintenance is to be allowed on-site over impervious surfaces, and contractor's equipment will be required to not exhibit hydraulic oil or fuel leakage prior to storage or use on the site. 10. Control De-Watering (the act of pumping groundwater or storm water away from an active construction site). Since the proposal consists of a foundation "crawl" grade that is below the finished grade outside of the foundation, in the event of water retention, a small channel may be created during construction to allow drainage of the foundation excavation which will likely require the use of BMP C209 and mulching BMP C121 until foundation backfill is completed. 11. Maintain Best Management Practices(BMP's). The owner Robert Weidner is to supervise all sub-contractors to insure that BMP's are maintained to their respective functional design. 12. Manage the Project. Construction is to be phased to prevent transport of water runoff or sediment, and limiting work during wet conditions where there may be a negative impact. Coordination of utility work—i.e., same trench use included, coupled with daily inspection and maintenance of systems is proposed. 2. Adjacent Areas. a. Description of the adjacent areas that may be affected by site disturbance(e.g., streams, lakes,wetlands, residential areas,roads). None to be affected by this project. b. Description of the downstream drainage path leading from the site to the receiving body of water (minimum distance of 400 yards). 5 . • • The proposed project will not result in or create off-site/downstream drainage paths especially as it relates to the Chimacum Creek watershed No work will be done is this area. 3. Environmentally Sensitive Areas. a. Description of environmentally sensitive areas that are on or adjacent to the site. None. b. Description of special requirements for working in or near environmentally sensitive areas. The applicant proposes to use "surface roughening" BMP C130 and soil stabilization with BMP C121 " Mulching" at sloped areas with a ratio of 3:1 horizontal to vertical and greater during construction, and until new vegetative growth is established This would normally be used for side cast soil mounding or berming to insure that there is no surface erosion or migration of surface water to the Chimacum Creek watershed 4. Erosion Problem Areas. Description of potential erosion problems on site in the context of the characteristics of the on-site soils(e.g.,erodibility, settle ability,permeability, depth,texture,soil structure). Published soil characteristics and topography of this site coupled with the proposed project stormwater mitigation measures and BMP's do not indicate any erosion problem potential for the site. 5. Construction Phasing. a. Construction sequence The applicant is to mark clearing limit area, establish construction access, foundation excavation, install proposed BMP's per plan, construct project, and then implement the permanent plan. b. Construction phasing(if proposed) Project to be started and completed within six months with no particular phasing requirements beyond that of a typical residential construction sequence. 6. Construction Schedule. It is known that the wet season is October 1 through April 30 a.

Findings: • Jefferson County Code 18.30.050 note 6 for Table 6 allows that"The administrator may reduce the minimum road setbacks if the strict application of such setback would render a legal lot of record unbuildable under the provisions of this code." The administrator reviewed your request on 6/27/2007 and determined that the setback from Andrew Ave (parcel number 962114211)of 2 feet, from the standard 20 feet reduced to 18 feet from the edge of the right-of-way may be granted in order to accommodate space requirements for septic drainfield and house size. This determination is based on Jefferson County Code as it stands today. Should the Jefferson County Code change, this determination may no longer apply. If you have any questions or concerns, please contact me at(360)379-4450.

The size determines whether a Stormwater Site Plan is required in conjunction with a stand-alone Stormwater management permit application, building permit application, or other land use approval application that involves stormwater review. The basic information will also be helpful for completing a Stormwater Site Plan,if required. PARCEL SIZE(I.E.,SITE) Size of parcel � 7 acres An acre contains 43,560 square feet. Multiply the acreage by this figure. Size of parcel in square feet is..... .C �:�= sq/ft Land-disturbing activity is any activity that results in movement of earth, or a change in the existing soil cover(both vegetative and non-vegetative) and/or the existing soil topography. Land disturbing activities include, but are not limited to clearing, grading, filling, excavation,and compaction associated with stabilization of structures and road construction. Native vegetation is vegetation comprised on plant species,other than noxious weeds,that are indigenous to the coastal region of the Pacific Northwest and which reasonably could have been expected to naturally occur on the site. Examples include species such as Douglas fir,western hemlock,western red cedar,alder,big-leaf maple,and vine maple;shrubs such as willow,elderberry,salmonberry, and salal;herbaceous plants such as sword fern,foam flower,and fireweed. LAND DISTURBING ACTIVITY,CONVERSION OF NATIVE VEGETATION,AND VOLUME OF CUT/FILL Calculate the total area to be cleared,graded,filled, excavated,and/or compacted for proposedAnswer the following two questions related to project. Include in this calculation the to elcleared for. conversion of native vegetation: Construction site for structures .2.S Does the project convert 3'4 acres or more of sq/fl native vegetation to lawn or landscaped areas? Drainfield,septic tank,etc. sq/ft Circle: Yes ('.iO) Well,utilities,etc. 0 sq/ft Does the project convert 2 Ys acres or more of Driveway,parking,etc. native vegetation to pasture? sq/ft Lawn,landscaping,etc. /k.)0 Circle: Yes No sq/ft - Other compacted surface,etc. sq/ft Indicate Total Volumes of Proposed: Total Land Disturbance `�G'- „I." ' sq/ft Cut i Fill ;2-5 (cu/yd) [over] • Impervious surface is a hard surface that either prevents or retards the entry of water into the soil mantle as under natural conditions prior to development. A hard surface area which causes water to run off the surface in greater quantities or at an increased rate of flow from the flow present under natural conditions prior to development. Common impervious surfaces include, but are not limited to roof tops, walkways, patios, driveways, parking lots or storage areas,concrete or asphalt paving, gravel roads, packed earthen materials, and oiled,macadam or other surfaces which similarly impede the natural infiltration of stormwater.

The following questions will help determine whether the proposed project is considered development or redevelopment. DEVELOPMENT v.REDEVELOPMENT Divide the total existing impervious surface above by the size of the parcel and convert to a percentage: % Does the site have 35%or more of existing impervious surface? Circle: Yes No FURTHER INSTRUCTIONS: If the answer is yes, the proposal is considered redevelopment and the attached Figure 2 should be used to determine the applicable Minimum Requirements. If the answer is no,the proposal is considered new development and the attached Figure 1 should be used. At this juncture,the applicant should refer to the applicable Flow Chart to determine the Minimum Requirements for stormwater management. DCD staff will help verify the classification of the project and the application requirements. For proponents of "small" projects who must comply only with Minimum Requirement #2—Construction Stormwater Pollution Prevention—an additional submittal is not required. The proponent is responsible for employing the 12 Elements to control erosion and prevent sediment and other pollutants from leaving the site during the construction phase of the project. Pick up the Construction Stormwater Pollution Prevention(SWPP) Best Management Practices (BMPs) Packet. Proponents of"medium"projects—those that must meet only Minimum Requirements #1 through #5—and for "large" projects—those that must meet all 10 Minimum Requirements—are required to submit a Stormwater Site Plan. DCD has prepared a submittal template of a Stormwater Site Plan, principally for rural residential projects. Complete the template in the Stormwater Site Plan Instructions and Submittal Template or prepare a Stormwater Site Plan using the step-by-step guidance in the Stonnwater Management Manual.
