SITE DEVELOPMENT REVIEW
Date Completed: December 28, 2022
Per Ordinance No: 09-10033-22 and Jefferson County Code (JCC) 18.40.440, site development
review (SDR) provides owners and developers of land an assessment of site requirements for
development of property. 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 parcels
942300005 and 942300006. This SDR 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. permits necessitating determination of
adequate potable water. 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 SDR.
Zoning: This parcel is zoned Rural Residential 1 dwelling unit per 5 acres (RR1:5). These are
substandard lots and are 2.06 and 2.05 acres.
Legal Lot of Record Status: Parcels 942300005 942300006 were platted under Cedarholm Villa
Tracts. The plats were recorded on September 2, 1907 under Auditor’s File Number 25348. A
boundary line adjustment altered the previous platted property under a 2005 county approval. This
was processed by Jefferson County Community Development under SUB2005-00013 and recorded
on July 26, 2005. This lot is a legal lot of record.
Critical Areas: Shoreline Conservancy, Wetlands, FEMA High Risk Coastal Flood Zone, Landslide
2
Hazard (High, Moderate and Slight), Unstable Slope, Seismic Hazard, Erosion Hazard, Coastal
Seawater Intrusion Protection Zone (SIPZ)
Shoreline Regulations: The South half of both lots are designated Shoreline Conservancy. The
Jefferson County Code 18.25.270 (4)(d) states:
(d) Building Setback. As established in Chapter 18.22 JCC, all new uses and developments,
including preferred uses and uses exempt from shoreline permit requirements, shall be located
landward of the standard buffer plus a 10-foot-wide building setback unless otherwise specified in
this program.
(e) Standard Buffer. The standard buffer shall be measured landward in a horizontal direction
perpendicular to the ordinary high water mark (OHWM) of the shoreline water body, and is a three
dimensional space that includes the airspace above, as follows:
(i) Marine Shores. A minimum buffer of 150 feet shall be maintained in all shoreline environments.
Wetlands: The south portion of the property is mapped as containing wetlands. A review of aerial
photography, contours and the US Topographical maps indicate potential wetlands on the property.
Any new development within the area would require a Wetland Delineation by a qualified wetland
specialist.
FEMA High Risk Coastal Flood Zone: If any development occurs within the mapped FEMA Flood
Zone, a Habitat Assessment will be required by a licensed biologist. Jefferson County Code (JCC)
18.22.430 (3)(a) states:
(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).
Landslide Hazard, Unstable Slope (Recent Slide and Unstable Slope), Seismic Hazard,
Erosion Hazard: The south boundary of the property contains a high landslide hazard, north of
that is a moderate landslide hazard, and the entire property is considered a slight landslide hazard.
Any development within the hazard areas will require a geotechnical report. Setbacks will be
required in areas that are mapped as high and moderate per Jefferson County Code (JCC)
18.22.530(8). Resolution number 37-83 states that projects may be permitted if slope stability can
be assured by a licensed engineer or geologist.
Coastal Seawater Intrusion Protection Zone (SIPZ): Coastal SIPZ: Jefferson County Code
(JCC) 18.22.330(8)(e)(i) states:
(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, Wetland Delineation, Habitat Assessment
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 Class IV-General Stormwater Permit with State
Environmental Policy Act (SEPA) review in order to avoid a 6-year Development
Moratorium per the state Forest Practices Act (FPA). Jefferson County recommends you
contact DNR to for FPA requirements.
Next Steps:
1. Obtain Geotechnical report
2. Obtain Wetland Delineation
3. Obtain Habitat Assessment
4. Apply for building permits
