Site development review is a required assessment, prior to development, of the physical aspects and constraints of the site for the purpose of development. While it 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 completed a site development review on parcel 994200005. This site development review reflects the conditions of the property at the date the review was completed. NOTICES: 1. Completion of this Site Development Review does not provide any assurance of future approvals for onsite sewage disposal or the ability to obtain potable water on the subject property. Use of any existing septic systems or water supplies for future development are not assured. Any activities that alter site conditions may limit or prevent future development of an onsite sewage system or a potable water supply. All future permitting which requires onsite sewage disposal on the property must comply with JCC 8.15 and WAC 246-272A at the time of application. Future proposals necessitating determination of adequate potable water must meet County and State requirements at the time of application. 2. A guaranteed right to development can only be established once a development permit application or building permit application vests pursuant to JCC 18.40.320. 3. A site development review does not vest a property to any regulations. Additional information may be required for development permits. Ground conditions may differ from those found in electronic review. There are no guarantees for development provided from this Site Development Review. PROPERTY REVIEW: Zoning: This lot is zoned Rural Residential 1 dwelling unit per 5 acres (RR 1:5). This is a sub-standard lot and is 1.89 acres in size. The zoning designation for the site support development of a new single-family residence. Legal Lot of Record Status: This lot was platted under, Seventh Avenue Acre Tracts. The plat was recorded on July 30, 1909 under Auditor’s File Number 28361. Setbacks: The setback from county right of way is 20 feet from the lot boundary per Jefferson County Code (JCC) 18.30.050. The setback to all other residential properties is 5 feet. 2 Critical Areas: Shoreline Environmental Designations (Natural, Priority Aquatic), DNR Water Body Forest Practices (Inventoried Shoreline), Wetlands, FEMA Flood Zones (High Risk Regulatory Floodway), Critical Aquifer Recharge Areas (SARPA +SUSC), Nitrogen BMP Shoreline Environmental Designations (Natural, Priority Aquatic): Development is prohibited waterward of ordinary high-water mark (OHWM). Administrative conditional use approval would be required for development landward of the OHWM per Jefferson County Code (JCC) 18.25.500. Any development will require a setback of 150 from Ordinary High Water Mark of stream/river shores per JCC 18.25.270(4)(e). Wetlands: Wetland is located near the Eastern portion of the parcel. Potential buffer is 225-feet; however, a Wetland Delineation Report is required to determine actual wetland buffers. All development must maintain the regulated wetland buffers and they must be maintained in natural, unaltered condition. A wetland delineation is needed per Jefferson County Code (JCC) 18.22.905. FEMA Flood Zones (High Risk Regulatory Floodway): A high risk flood zone is mapped on the Eastern half of the parcel. This proposal is for a septic system that may be located inside the FEMA Flood Zone. Any future development within the FEMA Flood Zone will have to comply with all regulations and flood proof requirements at the time of submittal. Jefferson County Code (JCC) Code 18.22.430 states the following in regards to FEMA Protection Standards (3) Habitat Assessment Requirements. (a) A habitat assessment that meets all the requirements of JCC 18.22.940 shall be submitted to the department for review if any portion of the proposed project occurs within a special flood hazard area (floodplain), as mapped by the Federal Emergency Management Agency (FEMA). (b) The administrator may request federal assistance in reviewing the submitted habitat assessment. (c) The administrator may waive the requirement to submit a habitat assessment only if: (i) The entire proposal meets one of the exemptions listed in Chapter 15.15 JCC and does not require a state hydraulic permit; (ii) The proposal requires a federal permit that is reviewed by federal agencies responsible for ensuring compliance with the Endangered Species Act (this could include, but is not limited to, project actions covered by separate consultation under Section 4(d), 7, or 10 of the Endangered Species Act); (iii) A habitat assessment previously has been prepared and the proposed project clearly fits within the nature and scope of that habitat assessment; or (iv) If FEMA approves an alternate process for Jefferson County to demonstrate compliance with the Biological Opinion (such as a programmatic review), this department may waive the requirement to submit a habitat assessment. [Ord. 5-20 § 2 (Appx. A)] Nitrogen Best Management Practice Requirements for Special Aquifer Recharge Protection Area (SARPA) and Susceptible Aquifer Recharge Area (SUSC): 3 SARPA+SUSC Critical Aquifer Recharge Area: Septic replacement designs must conform with requirements from Jefferson County Code (JCC) 18.30.180, 18.22, and Washington Administrative Code (WAC) 246. The Jefferson County Board of Health will determine the best management practices (BMPs) to meet minimum on-site sewage standards within both a susceptible aquifer recharge area and a special aquifer recharge protection area. The septic system component must be designed to fully treat all nitrogen and bacteria concerns as required by Jefferson County Department of Environmental Health. Required Reports: Wetland Delineation, Habitat Assessment Stormwater permitting: Stormwater Best Management Practices 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 Stormwater Management Manual for Western Washington produced by Washington State Department of Ecology. • Stormwater Clearing Permits are required for ALL property clearing of 7000 square feet or greater. This can be obtained through a building permit or if you wish to clear the property prior to developing you must obtain a separate stormwater permit. This is required prior to clearing for septic installation • Stormwater Clearing Permits or Vegetation Removal Permits are required for any tree removal if within a critical area regardless of square feet being cleared. • Impervious surface includes gravel surfaces. • Building permits must address stormwater. o A small project is any impervious surface under 2000 square feet. You must meet minimum requirement #2. o A medium project is any impervious surface from 2000 to 4999 square feet or 7000 or more square feet of clearing. You must meet Minimum requirements #1- #5. Including on site stormwater management. Jefferson County will request you to design a stormwater management system as part of your building permit to address roof and other hard surfaces. o A large project is any impervious surface from 5000 square feet or greater. You must meet all minimum requirements. Jefferson County will request you to design a stormwater management system as part of your building permit to address roof and other hard surfaces. If you reach a large project and your parcel is 5 acres or larger and you are not within an Urban Growth Area, an engineered stormwater plan is required to ensure low impact design standard is met. • If you plan on clearing the property and qualify under Department of Natural Resources (DNR) classification of needing a Forest Practices Application (FPA) you must work with our department first to obtain a Class IV General Stormwater Permit with SEPA to avoid a Development Moratorium. Jefferson County recommends you contact DNR to determine if your project meets their standard Next Steps: 1. Obtain wetland delineation by qualified wetland biologist. 2. Obtain habitat assessment for FEMA flood zone. 3. Apply for septic permit.
