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 acres An acre contains 43,560 square feet. Multiply the acreage by this figure. Size of parcel in square feel /2 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.

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 Stormwater Management Manual.

Use 2.0-in/hr soil permeability for infiltration calculations (minimum indicated in Soils Survey) Disturbance of native vegetation outside of the building envelopes will be minimized. Disturbed areas will be re-vegetated with native plants. The project is not tributary to a creek. Design storm is 25yr-24hr event with a depth of 2.1 inches as found on the isopluvials in NOAA Atlas 2,Volume IX SITE SPECIFIC STORM WATER MANAGEMENT Flows from impervious surfaces will be conveyed to an infiltration depression or one of three infiltration trenches. The different options are provided as equal alternative to allow flexibility depending on the specific configuration of each site. Contractor's Option 1: Infiltration Depression An infiltration depression can be constructed to provide 0.004 acre-feet*43560ft/acre = 174.2 cu feet. See"Subcatchment 1 S: Developed" on page three of this Reference. Exact sizing (length,width and depth)will be determined based on the site Contractor's Option 2: Infiltration Trench Sections Three trench sections (types) are provided to allow for site variations. The typical features of these are: All 3 types of trenches shall be: - 2-ft wide x 2-ft deep (excluding cover) x L (where L=the length as provided below) - placed"on contour" with 0% longitudinal slope - lined with filter fabric on all sides and have a minimum overlap at seams of 8-inches or as specified by manufacturer - Back-filled with drain rock Trenches using Section 1 or 2 shall be no closer than 5-feet(edge to edge)from any other stormwater,infiltration trench Trench Section 3 can be placed side by side and connected via a manifold if adequate area is • available"on contour" G:\Projects1The Vineyards\Design&Engineering\reference 2-quadra storm water.doc 1 of 6 REFERENCE #1 • Trench Calculation: The calculations that follow are for a unit of impervious surfacing (measuring 1000 square-foot) that drains to an infiltration trench. The calculations where performed using HydroCAD®by Applied Microcomputer Systems using the following methodologies to address and to compensate for limitations of the software: All Sections: - Are 2-ft wide x 2-ft deep (excluding cover) x L (where L= the length as provided below) - Soil permeability was converted from 2.0-inchThour to feet/minute (per unit algebra) 2.0-in/hr x 1-foot/12-hashes x 1-hour/60-minutes= 0.003-ft/hr - A 30% void space (detention volume)was used for the drain rock; this is shown as "open %" in the pond calculation summary. Section 1 - Is a conventional drain rock filled trench with a 4"perforated pipe.The storage volume of the pipe is considered negligible and is therefore not included in the calculations. Except as noted above in "All Sections" no compensation was required. Section 2 - Includes the use of a 12-inch pipe for additional storage volume. The void space is adjusted to account for the additional volume provided by the pipe. The calculations include adjustments at the '/, %2, and 3/depths of the pipe. - The"irregular section"method of calculation was used to address the irregularities/variations in the void space. Section 3 - Addresses a possible requirement of a single large infiltration "mat"; where multiple segments/lengths of"trench"are joined using a 4" pipe manifold by branching : - Each ; where a number of"trenches" are constructed side by side . Infiltration in this section is calculated through the base only.

The application was reviewed by the Jefferson County Department of Community Development staff on March 17, 2004 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: Critical Aquifer Recharge Area (Special Aquifer Recharge Protection Area), Coastal Seawater Intrusion Protection Zone, & Stormwater. 2.) 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. 3.) 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. 4.) The parcel is located within a coastal SIPZ (seawater intrusion protection zone)according to the County GIS map. There are voluntary and mandatory measures identified in the Jefferson County Seawater Intrusion Policy(Resolution 44-22, effective September 23, 2002)that apply to well drilling proposals and building permit applications on existing lots of record. A Coastal SIPZ is defined as: all islands and area within one-quarter mile of marine shoreline, but no history of chloride concentration above 100 mg/L in groundwater sources within 1000 feet. 5.) Marine shorelines and islands are susceptible to a condition that is known as seawater intrusion. Seawater intrusion is a condition in which the saltwater/freshwater interface in an aquifer moves inland so that wells drilled on upland areas cannot obtain freshwater suitable for public consumption without significant additional treatment and cost. Maintaining a stable balance in the saltwater/freshwater interface is primarily a function of the rate of aquifer recharge (primarily through rainfall)and the rate of groundwater withdrawals (primarily through wells). The Washington Department of Ecology is the agency with statutory authority to regulate groundwater withdrawal for individual wells in Jefferson County. New development, redevelopment, and land use activities on islands and in close proximity to marine shorelines in particular should be developed in such a manner to maximize aquifer recharge and maintain the saltwater/freshwater balance to the maximum extent possible by infiltrating stormwater runoff so that it recharges the aquifer. 6.) 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. 7.) To help prevent seawater from intruding landward into underground aquifers, all new development activity on Marrowstone Island, Indian Island and within 1/4 mile of any marine shoreline shall be required to infiltrate all stormwater runoff onsite. 8.) VOLUNTARY MEASURES 0 OASTAL&AT RISK SIPZ: • Water conservation measures: 1. Roof and other intercepted precipitation shall be routed to on-site detention ponds and/or other approved means and allowed to be released to the soil slowly. 2. Water collected from Storm water and roof catchments may be used for watering lawns and gardens. Unless catchment water has been treated to meet drinking water standards, there shall be no cross connections allowed between the potable supply and impounded water. 3. Water withdrawn from wells on each property shall not be used for watering of lawns and/or gardens. 4. Ground water withdrawn from each property shall be restricted to a rate of three (3) gallons per minute. 5. Installation of water conserving fixtures such as low flow toilets, faucets and shower restrictors and other water saving plumbing fixtures. 6. Landscaping plan (xeriscaping, native vegetation with minimal amounts of irrigation). Please NOTE that the above listed measures are not intended to be exhaustive, but rather is intended to be illustrative of the types of water conservation measures. 9.) VOLUNTARY MEASURES OF COASTAL &AT RISK SIPZ: 1. Installation of a flow meter. 2. On-going well monitoring for chloride concentration. 3. Submittal of monitoring data to County. 10.) MANDATORY MEASURES FOR COASTAL SIPZ: 1. For proof of potable water on a building permit application, applicant must utilize DOH-approved public water system if available. 2. If public water is unavailable, a qualifying alternative system may be used as proof of potable water or an individual well may be used as proof of potable water subject to the following requirement: a. Chloride concentration of a laboratory-certified well water sample submitted with building permit application. 3. If public water is unavailable, a qualifying alternative system may be used as proof of potable water. 11.) The applicant is proposing to create or add 4,357 square feet of impervious surface and 12,500 square feet of land disturbing activities, which is for the residence and garage. Sections 6.6 and 6.7 of the Jefferson County Unified Development Code requires that your proposal submit a Stormwater Plan for a Medium Project. A Master Basin Plan has been completed by Quadra Engineering for these lots. A retention/infiltration pond with a capacity of 642 cubic feet has been sized for this proposal by Mithun Architects/Designers/Planners. 12.) The project shall adhere to the Best Management Practices (BMPs)to control stormwater, erosion and sediment during construction. BMPs shall address permanent measures to stabilize soil exposed during construction, and in the design and operation of stormwater and drainage control systems. 13.) A Stormwater Plan for a Medium Project has been submitted and approved by the Department of Community Development. Once the subject permit has been issued the applicant shall fully implement the provisions of the submitted plan and contact the Jefferson County Department of Community Development to arrange a schedule to inspect the property for plan compliance. A Certificate of Occupancy will not be issued until the Department verifies plan compliance. No clearing for roadways or utilities shall occur on the project site until clearing necessary for the installation of temporary sedimentation and erosion control measures have been completed. 14.) Jefferson County determined that this proposal is categorically exempt from review under the State Environmental Policy Act (SEPA)pursuant to WAC 197-11-800(1)(b)(i). 15.) Outdoor residential storage shall be maintained in an orderly manner and shall create no fire, safety, health or sanitary hazard. 16.) Not more than two (2)unlicerid or inoperable vehicles shall be stored only lot less than one-half acre unless totally screened from view of neighboring dwellings and rights-of-way. Such screening shall meet all applicable performance and development standards specific to the district in which the storage is kept, and shall be in keeping with the character of the area. Screening shall meet the requirements of Unified Development Code (UDC) Section 6. Outdoor storage of thirteen (13)or more unlicensed or inoperable vehicles is prohibited except in those districts where specified as an automobile wrecking yard or junk (or salvage)yard and allowed as a Permitted Use in Table 3-1 of the UDC, and such storage shall meet the requirements of UDC Section 4.10. In no case, shall any such unlicensed or inoperable vehiclesbe stored in an Environmentally Sensitive Area (ESA). 17.) The proposal is comprised of Lots 35-39 Block 143 of Irondale Division 6 recorded through AF#30490 on June 28, 1910. A Restrictive Covenant has been required, and has been filed through AF#482759 on April 1, 2004. This property is designate Rural Residential 1 dwelling per 5 acres by the Jefferson County Comprehensive Plan Adopted August 28, 1998. 18.) Maximum lot coverage is not to exceed 25%. Lot coverage is defined as amount of impervious surface which includes roof tops, driveways, concrete, etc. 19.) The proposal has 35 percent impervious surface and 25 percent is the limit in the Rural Residential 1 d.u./5. Note 15 on Table 6-1states that on pre-existing lots of records located in the Rural Residential districts that the impervious surface should be met to the maximum extent practicable. This proposal meets this criteria. 20.) The building height is not to exceed 35 feet. 21.) 20 foot setback from the edge of the right-of-way of Victory Lane (west). There is a 5 foot side and rear setback. 22.) The site plan as submitted with the Building Permit Application (BLD 04-00157)for the residence & Decks on March 15, 2004 has been reviewed for consistency under the UDC, and has been approved by Jefferson County Department of Community Development. Any modifications, changes, and/or additions to the stamped, approved site plan dated May 3, 2004 shall be resubmitted for review and approval by Jefferson County Department of Community Development. 23.) This approval is for a residence and deck only. Any future permits on this site are subject to review for consistency with applicable codes and ordinances and does not preclude review and conditions which may be placed on future permits.
