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 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. Jefferson County Department of Community Development Planning Staff has completed a site development review on parcel 921042007. This site development review reflects the conditions of the property at the date the review was completed. Zoning: This parcel is zoned rural residential 1 dwelling per 5 acres (RR1:5). This parcel is conforming and is 10.37 acres. Legal Lot of Record Status: This parcel is an acreage parcel. Deeds recorded on the property were reviewed for any indication that the lot may have been illegally created. Our records indicated that the property has maintained the same legal description throughout our records and there is no indication that the lot was illegally created or changed. This parcel qualifies for Jefferson County Code (JCC) 18.12.070(4)(e): “The lot was approved by the county for a residential on-site sewage system, accessory dwelling unit or primary residence, or any land use permit for the purpose of siting a primary residence, and the approval has not expired”. SEP2021-00222 was approved on June 29, 2022. Critical Areas: High Risk Seawater Intrusion Protection Zone (SIPZ). High-Risk Seawater Intrusion Protection Zone (SIPZ): (A) Mandatory Actions. (I) Water conservation measures; (II) For proof of potable water on a building permit application, applicant must utilize a Washington Department of Health-approved public water system if available; (III) If public water is unavailable, meaning the subject property is not within a current water service area, an individual well may only be used as proof of potable water subject to the following requirements: 1. Variance from the WAC Title 173 standards granted by the Washington Department of Ecology per WAC 173-160-106 for a new groundwater well within 100 2 feet of a sea-salt water intrusion area per WAC 173-160-171 (i.e., within 100 feet of a groundwater source showing chloride concentrations above 200 mg/L or within 100 feet of the marine shoreline) and with the submittal of a hydrogeologic evaluation that satisfies all the requirements or a hydrogeologic evaluation contained in JCC 18.22.930(2)(b); 2. For an existing groundwater well not subject to a Washington Department of Ecology variance, the applicant must provide a hydrogeologic evaluation that satisfies all the requirements or a hydrogeologic evaluation contained in JCC 18.22.930(2)(b), which shall be transmitted to the Washington Department of Ecology for review, demonstrating that use of the well does not cause any detrimental interference with existing water rights and is not detrimental to the public interest; 3. Chloride concentration of a laboratory-certified well water sample submitted with building permit application; 4. If chloride concentration exceeds 250 mg/L in a water sample submitted for a building permit, then the property owner shall be required to record a restrictive covenant that indicates a chloride reading exceeded the U.S. Environmental Protection Agency secondary standard (250 mg/L) under the National Secondary Drinking Water Regulations; 5. Installation of a source-totalizing meter flow; 6. Ongoing well monitoring for chloride concentration; and 7. Submittal of flow and chloride data to the county per monitoring program; and (IV) If public water is unavailable, a qualifying alternative system may be used as proof of potable water. (iv) Marrowstone Island. Since Marrowstone Island is a sole source aquifer and a high risk SIPZ, and the island is served by public water, proof of potable water connection to the public water supply will be required for all lots in the project. Required Reports: None Stormwater permitting: 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 3 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: Apply for septic expansion permit.
