SDR is required prior to development. The result of SDR is a description of the physical aspects and constraints of the site for the purpose of guiding development. While SDR will not vest a property to development regulations, it provides for a professional analysis of the site according to current development regulations. Jefferson County Department of Community Development Planning Staff has SDR on parcel 996400001. This SDR reflects the conditions of the property at the date the review was completed. NOTICE TO APPLICANT: The purpose of the SDR is to provide owners and developers of land with a professional assessment of possible site development issues without first applying for permits. As this is a preliminary review of available GIS mapping data and nontechnical information supplied by the applicant, it is NOT a guarantee that development can occur in the manner described. However, it is a valuable tool to allow applicants to plan out the development process in advance. Here are three key disclaimers: • Site Development Review DOES NOT VEST applicants to a particular set of regulations; that can only be accomplished in the manner set out in JCC 18.40.320, which in many cases requires filing of a building permit application. • Completion of this review does not guarantee future approval for an onsite septic system. An applicant must apply for and complete all required permitting pursuant to chapter 8.15 JCC and WAC 246-272A. Use of older septic systems is not guaranteed. • The adequacy of a potable water supply cannot be assessed until the time of building permit application. Proposals necessitating a determination of adequate potable water supply must meet all county and state requirements in effect at the time of application. PROPERTY REVIEW: Zoning: This parcel is zoned Rural Residential, one dwelling unit per five acres (RR 1:5). This is a conforming lot and is 6.23 acres in size. Legal Lot of Record Status: This parcel was platted under a Long Plat Subdivision, Lagoon View Long Plat. The plat was recorded on December 22, 1997 under Auditor’s File Number (AFN) 406492. This parcel has not changed since platted and remains a legal lot of record because it was platted after August 11, 1969. 2 Setbacks: The setback from Whitney Road is twenty (20) feet from the parcel boundary per Jefferson County Code (JCC) 18.30.050. The setback to all other residential properties is five (5) feet. If any easements, including an ingress/egress easement, there may be a 20- foot setback per Jefferson County Code (JCC) 18.30.050. Critical Areas: Slight Landslide Hazard, Shoreline Slope Stability: Unstable Slope Geohazards: The following are mapped geohazards on this property: Slight Landslide Hazard and Shoreline Slope Stability: Unstable Slope. There is a mapped slight landslide hazard on the eastern portion of the property. At this time, Jefferson County Code (JCC) does not regulate slight landslide hazards. However, this hazard may require a geotechnical report in the future depending on JCC regulation changes/updates. The shoreline slope stability: unstable slope designation, mapped on the eastern portion of the property, is a regulated geohazard under Chapter 18.22 JCC. A prescriptive setback of 25 feet with an additional 15-foot impervious surface setback for a total of 40-foot setback from top of slope was determined for the property according to the standards of JCC 18.22.530(8)(b)(i) and any development or land disturbance within 200 feet of the mapped hazards must be evaluated in a geological assessment per JCC 18.22.540(4)(b). All of these hazards are regulated under Jefferson County Code (JCC) 18.22. Any new development requires a geotechnical report that addresses all of the listed geohazards on site. JCC 18.22.520 Regulated Activities states: (1) Any development activity or action requiring a project permit or any clearing within an erosion or landslide area shall: (a) Comply with the requirements in an approved geotechnical report when one is required, including application of the largest buffer or building setback; (b) Utilize best management practices (BMPs) and all known and available technology appropriate for compliance with this chapter and typical of industry standards; (c) Prevent collection, concentration or discharge of stormwater or groundwater within an erosion or landslide hazard area and be in compliance with JCC 18.30.070, Stormwater management standards; and (d) Minimize impervious surfaces and retain vegetation to minimize risk of erosion or landslide hazards. (2) Any development activity or action requiring a project permit or any clearing within an erosion or landslide area shall not: (a) Result in increased risk of property damage, death or injury; (b) Cause or increase erosion or landslide hazard risk; (c) Increase surface water discharge, sedimentation, slope instability, erosion or landslide potential to adjacent downstream and down-drift properties beyond predevelopment conditions; (d) Adversely impact wetlands, fish and wildlife habitat conservation areas or their buffers; or 3 (e) Be identified as a critical facility necessary to protect public health, safety and welfare. This includes, but is not limited to, schools, hospitals, police stations, fire departments and other emergency response facilities, nursing homes, and hazardous material storage or production. [Ord. 5-20 § 2 (Appx. A). Required Reports: Geotechnical report Stormwater permitting: Stormwater Best Management Practices (BMPs) shall be implemented as conditioned on any permit approvals and as required in the current edition of the Stormwater Management Manual for Western Washington. Jefferson County has adopted the most current edition of the manual produced by Washington State Department of Ecology. • A Stormwater Management Permit is required for grading of 500 cubic yards or more, land-disturbing activities of 7,000 square feet or more, or creation of 2,000 square feet or more of impervious surface. This approval may be obtained through a building permit or, if you wish to clear the property prior to building, you must obtain a separate stormwater management permit. This is required prior to clearing and grading for related development, such as septic system installation or road/driveway construction. • Stormwater Management Permits or Vegetation Removal Permits are required for any tree removal within a critical area or its buffer regardless of square footage cleared. • Impervious surface includes gravel surfaces. • Building permits must address stormwater. o A small project is any impervious surface under 2,000 square feet. You must meet minimum requirement #2 from the manual. o A medium project is any impervious surface from 2,000 to 4,999 square feet or 7,000 or more square feet of clearing. You must meet minimum requirements #1-#5, including on-site stormwater management. The building permit application should include a designed stormwater management system to address runoff from the roof and other hard surfaces. o A large project is any impervious surface from 5,000 square feet or greater. You must meet all minimum requirements. The building permit application should include a designed stormwater management system to address runoff from the roof and other hard surfaces. If your project meets the large project threshold, your parcel is five acres or larger, and you are not within an Urban Growth Area, an engineered stormwater plan is required to ensure low-impact design standards are met. • If you plan on clearing the property and would be required by the state Department of Natural Resources (DNR) to submit a Forest Practices Application (FPA), you must work with our department first to obtain a Stormwater Management Permit with State Environmental Policy Act (SEPA) review, in association with a Class IV-General FPA, in order to avoid a 6-year Development Moratorium per the state Forest Practices Act. Jefferson County recommends you contact DNR for FPA requirements. Next Steps: 1. Obtain and submit geotechnical report. 2. Apply for permit(s).
