SITE DEVELOPMENT REVIEW
Per Ordinance No: 09-10033-22 and Jefferson County Code (JCC) 18.40.440, site development
review (SDR) process will provide owners and developers of land an assessment of site
requirements for development of a parcel.
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 001061005. 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 unit per 10 acres (RR1:10). This is a non-conforming lot and is 8.62 acres. Legal Lot of Record Status: This parcel is an acreage parcel. Deeds recorded on the property
dating back to 1966 were reviewed for any indication that the lot may have been illegally created,
no indications were found. A survey was completed on the property August 8, 2022. This was
recorded under Auditors File Number (AFN) 655829. This lot has been determined to be a legal lot
of record. Critical Areas: Shoreline Natural Designation, Mapped Non-Fish Stream, Mapped Wetlands, High
Landslide Hazard, Unstable Slope, Seismic Hazard, Coastal Seawater Intrusion Protection Zone
(SIPZ).
Natural Shoreline Regulations: Shoreline Natural designation is present on the property and extends from Ordinary High-Water Mark (OHWM) and landward 200 feet. The required shoreline buffer is 150-feet from OHWM. Any development within the 200-foot jurisdiction requires an
administrative shoreline conditional use approval. A pre-application conference with the
Department of Ecology (ECY) was held on October 14, 2022 for this proposal. Any application for
septic, building, or other development must be outside of the 200-foot jurisdiction prior to
receiving the approval from ECY for the proposal.
Mapped Non-Fish Stream: There is a mapped non-fish habitat stream crossing through the middle of the parcel. Lidar imagery, US topography maps, and contours were evaluated. If a
stream does exist, all new development must adhere to required 50 to 75-foot buffers. If the grade
is over 20%, a 75-foot buffer shall be maintained, if under 20% grade, a 50-foot buffer shall be
maintained. An additional 5-foot building setback will apply to either buffer.
Wetlands: Wetlands are mapped on the property, but review of Ecology shoreline photos and site contours indicate that this mapped wetland is only associated with the shoreline mapping and
2
wetlands likely do not exist on the property at this time. High Landslide Hazard, Unstable Slopes: The western portion of the property has been mapped
as having an unstable slope and moderate landslide hazard. If any development occurs in the slope
stability area, a geotechnical report will be required.
Seismic Hazard: The western portion of the property has been mapped as a seismic hazard. Any new development within the hazard area requires a geotechnical report. Coastal Seawater Intrusion Protection Zone (SIPZ): The Jefferson County Code 18.22.330(8)(e)(i) states that:
(i) Coastal SIPZ.
(A) Voluntary Actions. Voluntary actions may include but are not limited to:
(I) Water conservation measures; (II) Ongoing well monitoring for chloride concentration; and (III) Submittal of data to the county.
(B) Mandatory Actions.
(I) For proof of potable water on a building permit application, applicant must utilize DOH-
approved public water system if available;
(II) If public water is unavailable, meaning the subject property is not within a current
water service area, an individual well may be used as proof of potable water subject to the following requirements: 1. Chloride concentration of a laboratory-certified well water sample submitted with building
permit application; and
2. Installation of source-totalizing meter (flow);
(III) If public water is unavailable, a qualifying alternative system may be used as proof of
potable water. Required Reports: Geotechnical Report Stormwater permitting: A class IV general stormwater permit was applied for; however, it cannot
be reviewed until approval for the shoreline conditional use permit is received from ECY. The
applicants still need to apply for the shoreline conditional use permit. 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
3
and you are not within an Urban Growth Area, an engineered stormwater plan is required to ensure low impact design standard is met.
o 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. Get Geotechnical Report
2. Apply for Shoreline Conditional Use Permit
3. If approval for Shoreline development is received from ECY, can apply for other
development permits. DCD can continue to process Class IV General
Stormwater Permit
4. If Class IV general is approved, then applicant can apply with DNR for Forest
Practice Permit
