MUST MAINTAIN A MINIMUM OF 10' SETBACK FROM EDGE OF DISPOSAL COMPONENT TO DOWNGRADIANT STORMWATER DISPERSION. MUST COLLECT AND DIVERT ALL SOURCES OF DRAINAGE AWAY FROM SEPTIC TANK, RESERVE & DRAINFIELD. MUST COMPLY WITH ALL PERMIT CONDITIONS, STATE AND LOCAL CODE. 2.) 10' SEPARATION REQUIRED BETWEEN A WATER LINE AND ALL PORTIONS OF THE ONSITE SEWAGE SYSTEM; EFFLUENT TRANSPORT LINE, TANKS, TREATMENT AND DISPOSAL COMPONENTS 3.) PRIOR TO OCCUPANCY& FINAL OF BUILDING PERMIT -- FINAL APPROVAL OF SEPTIC SEP06-187 IS REQUIRED. 4.) The application was reviewed by the Jefferson County Department of Community Development staff on June 12, 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: landslide hazard area 2; SUSC aquifer recharge area; coastal SIPZ. 5.) 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. 6.) Susceptible Aquifer Recharge Areas are those with geologic and hydrologic conditions that promote rapid infiltration of recharge waters to groundwater aquifers. 7.) Geologically Hazardous Areas in Jefferson County are characterized by slope, soil type, geologic material, and groundwater that may combine to create problems with slope stability, erosion, and water quality during and after construction or during natural events such as earthquakes or severe rainstorms. 8.) 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. 9.) 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. 10.) A vegetative buffer of 70-feet shall be permanently maintained from the top or edge of the Landslide Hazard Area. All buffers shall be measured perpendicularly from the top of the Landslide Hazard Area. 11.) A Geotechnical Report dated March 13, 2007 prepared by Allen Hart Engineering Geologist was submitted in conjunction with this application. The report addressed the stability of the geologic hazard area. A minimum setback of 70-feet shall be measured perpendicularly from the top of the geologic hazard to the proposed residence. 12.) PRIOR TO FINAL BUILDING O10PANCY, PROPONENT SHALL SUBMITIIRITTEN LETTER FROM ALLEN HART, THE GEOLOGIST WHO PREPARED THE GEOTECHNICAL REPORT DATED MARCH 13, 2007 STATING THAT THE STRUCTURE AND/OR FACILITIES HAVE BEEN CONSTRUCTED IN CONFORMANCE WITH THE REQUIREMENTS OF THE "GEOTECHNICAL REPORT." THE LETTER SHALL BE WET-STAMPED BY THE LICENSED GEOLOGIST/ENGINEER. 13.) Landslide Hazard Areas and their associated buffers shall remain naturally vegetated. Should buffer disturbance occur during construction, the Unified Development Code (UDC)Administrator shall require replanting with native vegetation. No alterations shall be made to the Landslide Hazard Area or its associated buffer without prior authorization by the UDC Administrator. 14.) Prior to and during approved construction activities, the perimeter of the landslide hazard area buffer shall be marked with a temporary sign. The sign shall be placed in such a manner that it can be directly observed from the construction area. The sign shall contain the following statement: "Landslide Hazard Area and Buffer- Do not Remove or Alter Existing Vegetation." 15.) All construction activities shall not encroach upon the landslide hazard area buffer. This includes the storage or preparation of materials. 16.) The applicant shall permanently separate the boundary of the Landslide Hazard Area Buffer from the remainder of the subject property through installing logs, trees, a hedge row, or any other prominent physical marking approved by the UDC Administrator. 17.) 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. 18.) 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. 19.) The property owner shall comply with Water Conservation Measures (per list maintained by the UDC Administrator). 20.) An Engineered Storm Drainage Report, Stormwater Maintenance Manual and Stormwater Site Plan prepared by ADA Engineering 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. 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. 21.) PRIOR TO FINAL BUILDING OCCUPANCY, PROPONENT SHALL SUBMIT AN ORIGINAL WET-STAMPED WRITTEN LETTER FROM ADA ENGINEERING STATING THAT THE STORMWATER FACILITY HAS BEEN CONSTRUCTED IN ACCORDANCE WITH THE REQUIREMENTS OF THE "STORMWATER DRAINAGE REPORT" DATED APRIL 3, 2007 AS SIGNED BY HERBERT A. ARMSTRONG OF ADA. 22.) 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). 23.) The revised site plan dated June 19, 2007 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 June 21, 2007 shall be resubmitted for review and approval by Jefferson County Department of Community Development. 24.) This approval is for a single family residence with attached garage and a detached garage with a satellite bedroom 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. 25.) The parcel has been designated as RR 1:5 under the Jefferson County Comprehensive Land Use Map effective August 28, 1998. 26.) A Declaration of Restrictive Covenant has been recorded on May 25, 2007 under AFN 523827 for the purpose of limited capacity of the on-site sewage disposal system to 3 bedrooms. 27.)

It is in the SE of Section 34, Township 25 N, Range 1 W, WM, Jefferson County. The subject property is Lot 2 of the Kennard Short Plat (SUB95- 0031). Access to the site is via Beach Drive. This drainage report details the location and distribution of stormwater resulting from development. Pre-Development Condition In the pre-development state the project site totaled 2.65 Acres of mostly gradually sloping terrain with established second growth timber. The drainage path for the site is downhill to the west, the north, and the east. Stormwater runoff flows north to an unnamed creek in which it flows west into Dabob Bay. As to the properties surrounding, they all contain established 2nd growth, although the land to the north contains a clearing and the land to the east contains a small lake. The stormwater runoff from upstream is minimal because of topography(slopes drop off on three sides of this land). Post-Development Condition The proposed development for this project is the construction of a private residence, a small detached building, a driveway connecting these structures to Beach Drive. Stormwater mitigation facilities for this development are also proposed. The stormwater runoff from the building roofs is to flow to level spreaders through pipes. Since only an insignificant gutter system is to be provided, the stormwater is to fall off of the roof into trenches in the ground which are to contain perforated pipes. The level spreaders are to disperse the stormwater down the slope to the north. The stormwater runoff from the private driveway is to be conveyed to the ditches that are to be placed along the sides of the driveway. The stormwater in the ditches is to flow into tightline through a CB on the east side of the driveway. This tightline is to convey the stormwater to yet another level spreader for the purpose of dispersion to the north. The CB mentioned above is to contain an oil/water separator for the containment of possible oil spills. As for areas in Lot 2 not affected by the proposed development, they will be left undisturbed along with the native vegetation except during the installation of level spreaders. Theory of Analysis The enclosed drainage computations were calculated using the Western Washington Hydrology Model version 2.5f as required by the Stormwater Management Manual for Western Washington. Pre-developed and post-developed areas are shown in Exhibit A. Pre-development site conditions are established secondary growth timber with slope ranging from 0% to 55% (70 ft top of bank setback has been applied). Minimum Requirements #1.

For Tax Lot 003, upstream property is west of it. Properties to the south of Tax Lot 019 are developed and have their own stormwater management facilities. Also, property to the west of Tax Lot 003 and 019 are undeveloped and covered with established secondary growth. Thus, upstream properties of the project site do not contribute stormwater runoff to the project site. Downstream Summary Downstream properties to the project site are properties to the north and east for Tax Lot 003 and east for Tax Lot 019. The stormwater runoff from the proposed road is collected and detained on the project site. The detained stormwater will be released at a controlled rated and flowed northward with the natural contour to a branch of Anderson Creek. The released rate of the detained stormwater is matched with the pre-developed flow rate of the stormwater runoff from the project site. Thus, the project site will not contribute stormwater runoff to the properties to the east for both tax lots. Also, the project site will not significantly contribute to properties north of Tax Lot 003. As a result, the project site will not significantly impact any properties downstream. Sediment and Erosion Control During the construction phase it may be possible that Erosion could occur resulting in the transportation and deposit of sediments. This shall be prevented by conducting construction during the summer months when rain fall is less likely, installing silt fencing around the down gradient boundaries, spreading straw over disturbed areas that construction has concluded in, and finally reseeding all disturbed areas. If these measures are installed and properly maintained, sedimentation and erosion will be mitigated. • • SON e C �` c JEFFERSON COUNTY °o r , DEPARTMENT OF COMMUNITY DEVELOPMENT 621 Sheridan Street • Port Townsend • Washington 98368 Q 360/379-4450 • 360/379-4451 Fax IN hthttp://www.co.jefferson.wa.us/commdevelopment/ STORMWATER SITE PLAN SUBMITTAL TEMPLATE MLA# ' 3 PROJECT/APPLICANT NAME: Coover Site Development Please answer all of the following questions to the best of your ability.

Parcel is with in one quarter mile of Dabob Peninsula's Western shore surrounded by established second growth. Some of the adjacent parcels have single family residences on them. 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. Storm water is to flow from the rooftop of each structure to the corresponding level spreader for dispersion. Storm water is to flow from the new driveway to the roadside ditch to the collection basin with the oil/water separator in it, to the other collection basin,to a spreader for dispersion. 10. If the project requires the use of stormwater treatment facilities, describe the types of stormwater treatment facilities proposed for use on the site.
