BOARD OF COUNTY COMMISSIONERS
AGENDA REQUEST
TO: Board of County Commissioners
Philip Morley, County Administrator
FROM: Patty Charnas, Department of Community Development Director
DATE: February 3, 2020
SUBJECT: Planning Commission Recommendations on Critical Area Ordinance (CAO)
updates
STATEMENT OF ISSUE:
The Planning Commission is prepared to deliver its recommendations regarding updates to the
Critical Areas Ordinance (CAO), located at 18.22 Jefferson County Code (JCC) including
attendant updates to Definitions (18.10 JCC) and to Agricultural Activities and Accessory
Uses (18.20.030 JCC).
ANALYSIS:
On December 2, 2019, the BoCC asked the Planning Commission to begin work immediately,
in coordination with County staff, on legislation to revise the Critical Areas Ordinance (CAO).
On December 4, 2019, the Planning Commission was given a briefing on the Critical Areas
Ordinance Regulatory Reform Task recommendations report. That briefing also described a
substantially revised section on protecting critical areas in areas of agricultural activities. On
December 18, 2019, the Planning Commission received a staff briefing on all proposed
updates to the entire CAO and an overview of the staff report.
The Planning Commission discussed the draft CAO on January 8, 2020. A notice of hearing
was published for a hearing on January 22, 2020.
The Planning Commission conducted a public hearing on January 22, 2020 to receive public
testimony and written comments during a comment period from January 8, 2020 until 4:30pm
on Friday, January 24, 2020. Approximately ten written comments were received and five
individuals testified at the public hearing. The majority of the comments were directed to the
new article on protecting critical areas in areas of agricultural activities with most of those
comments offering support and/or minor change.
Regular Agenda
During the week of January 27 through 31, the Planning Commission deliberated on the draft
CAO, considering staff recommended revisions and public comment received. The purpose of
this meeting is to formally deliver the Planning Commission Findings of Fact,
Recommendations and Conclusions on the 2020 Critical Areas Ordinance update. The Chair of
the Planning Commission, Michael Nilssen, will be present to participate in this agenda
discussion.
FISCAL IMPACT:
Cost of work associated with the County's update to its CAO and related activities are largely
supported by the county's general fund.
RECOMMENDATION:
Receive the Planning Commission's Recommendations on updates regarding updates to the
Critical Areas Ordinance (CAO) (18.22 JCC) and to Definitions (18.10 JCC) and Agricultural
Activities and Accessory Uses.

STAFF DRAFT
To: Board of County Commissioners
From: Planning Commission
Date: February 3, 2020
Subject: Planning Commission findings and recommendations on proposed amendments to Title
18 Jefferson County Code (Unified Development Code) relating to Critical Areas
Honorable Commissioners Brotherton, Sullivan and Dean:
The Jefferson County Planning Commission is pleased to transmit to the Board of County Commissioners
("BOCC") our findings and recommendations on amendments to Title 18 Jefferson County Code ("JCC')
relating to critical areas. Specifically, the Planning Commission recommends amendments to Chapter
18.10 JCC (Definitions), Chapter 18.22 JCC (Critical Areas Ordinance), and JCC 18.20.030 (Agricultural
Activities and Accessory Uses). The findings and recommendations presented in this transmittal, were
approved with a unanimous vote of the Planning Commission on January 30, 2020. This report
summarizes the process and the work product related to the proposed ordinance.
The Planning Commission respectfully puts forward the following findings and recommendations. We
further recommend that these regulations be adopted. We believe these recommended regulations reflect
widely -held sentiments in Jefferson County based upon the hearing record.
Process
The County has been working on its periodic review and update to the critical areas ordinance ("CAO")
since 2014. The Growth Management Act (GMA, Chapter 36.70A RCW) requires counties to periodically
review and update their comprehensive plans and development regulations, including critical areas
ordinances. Updates to critical areas must include best available science and give special consideration
to anadromous fish. The County was granted a two-year extension by the Washington Department of
Commerce to the GMA statutory 2016 deadline to have all updates to the comprehensive plan and
implementing regulations complete. The County continued working on updating its CAO but was unable
to meet the extended deadline causing the county to be out of compliance with GMA.ln 2018, the
Planning Commission concluded its periodic review and update of the Jefferson County Comprehensive
PC Findings and Recommendations on Proposed Amendments to Title 18 Jefferson County Code (Unified
Development Code) Relating to Critical Areas
To Board of County Commissioners
Plan and development regulations, excluding critical areas by developing findings of fact and
recommendations to the Jefferson County Board of County Commissioners. In 2018, the Board of County
Commissioners adopted a periodic review and update of the Jefferson County Comprehensive Plan and
development regulations, excluding critical areas. The 2018 Comprehensive Plan continued a long
commitment to protecting the environment and public health while emphasizing support for affordable
housing, economic development, agriculture, and regulatory reform.
In March, 2019, the Board passed Resolution 17-19 establishing a program of regulatory reform directing
the Jefferson County Department of Community Development ("DCD") and Jefferson County
Environmental Public Health ("EPH") to reduce regulatory burdens during scheduled updates to county
codes and county rules. The incomplete updates to the CAO were specifically referenced as an
opportunity to streamline review processes and permit applicant requirements while protecting critical
areas functions and values. In July 2019, the Jefferson County Board of County Commissioners ("Board")
established a Critical Areas Ordinance Regulatory Reform Task Force ("Task Force") and appointed its
members to make recommendations to the Planning Commission, DCD, and Board on improving the
understandability and administration of the CAO. Task Force members included a DCD staff member and
a Planning Commission member. The Task Force met nine times between August and November 2019.
The Task Force's efforts culminated with a report recommending improvements to the CAO. The Task
Force report was based largely on considering CAO development standards existing in other GMA-
compliant counties.
In September 2019, the Board passed Resolution 50-19 recognizing the progress of updating the CAO,
acknowledging the rigorous and on-going public participation processes, and committed to completing the
CAO periodic review and update by early 2020
On December 2, 2019, the Board asked the Planning Commission to begin work immediately, in
coordination with County staff, on legislation to revise the CAO. On December 4, 2019, the Planning
Commission was given a briefing on the Task Force's report. On December 18, 2019, the Planning
Commission received a briefing on the staff report and on all updates to the CAO including the revised
section on agriculture.
On January 8, 2020, the Planning Commission held a briefing session on the draft CAO. A notice of
hearing was published for a hearing on January 22, 2020.
Public Hearing
On January 22, 2020, the Planning Commission held a public hearing, accepting verbal and written
testimony on the draft CAO. The Planning Commission accepted written comments from January 8, 2020

Required Findings
In support of this recommendation for the development regulations located in Title 18 JCC, the Planning
Commission enters the following findings and conclusions:
Required findings; adapted from JCC 18.45.080 (1)(b)(i-iii)
(i) Have circumstances related to the proposed amendment and/or the area in which it is
located substantially changed since the adoption of the Jefferson County Comprehensive
Plan?
The Planning Commission finds that circumstances related to the recommended code as
proposed have not substantially changed since the adoption of the Jefferson County
Comprehensive Plan. The Comprehensive Plan's Periodic Review and Update was
completed in December 2018; however, the CAO periodic review and update was
postponed. This proposal brings the CAO development regulations in alignment with the
2018 Comprehensive Plan.
(ii) Are the assumptions upon which the Jefferson County Comprehensive Plan is based no
longer valid; or is new information available which was not considered during the
adoption process or any annual amendments of the Jefferson County Comprehensive
Plan?
The assumptions upon which the Jefferson County Comprehensive Plan was based are
still valid. However, the Planning Commission finds that new information relating to state
rules for critical area ordinance updates have changed and that county statements of
legislative intent have changed through the passage of two resolutions regarding critical
areas and regulatory reform. Further, additional best available science and public
engagement have resulted in new information which informs this recommendation.
(iii) Does the proposed amendment reflect current, widely held values of the residents of
Jefferson County?
PC Findings and Recommendations on Proposed Amendments to Title 18 Jefferson County Code (Unified
Development Code) Relating to Critical Areas
To Board of County Commissioners
The Planning Commission finds the proposal reflects currently widely held values.
The proposed CAO is consistent with the 2018 Comprehensive Plan which
represents recent resident input in the planning process. See the following
Framework Goal: Framework Goal VI Environmental Conservation (Foster
environmental stewardship, preserve clean air and water, and protect fish and
wildlife habitat. Anticipate and respond to climate change with mitigation and
adaptation strategies.)
Further, a robust public participation process included a diverse group of
appointed stakeholders, including the Critical Areas Ordinance Regulatory Reform
Task Force, which met and delivered recommendations on the CAO to the
Planning Commission. The testimony received by the Planning Commission during
the public hearing and comment period confirm that the proposal meets the
currently widely held values. Therefore, the Planning Commission finds that the
proposal reflects currently widely held values.
II. Required Findings from JCC 18.45.050(4)(b)(i) through (4)(b)(vii)
Growth Management Indicators
i) Is growth and development as envisioned in the Comprehensive Plan occurring faster or
slower than anticipated, or is it failing to materialize?
The Planning Commission finds that they do not have enough information to determine if
growth is occurring at the rate envisioned in the Comprehensive Plan, as the projections
were recently updated in December 2018. However, it appears that the growth is occurring
as envisioned in the Comprehensive Plan.
ii) Has the capacity of the county to provide adequate services diminished or increased?
The Planning Commission finds that the capacity of the County to provide adequate
services has not diminished or increased relating to this proposal.
iii) Is there sufficient urban land, as designated and zoned to meet projected demand and need?
PC Findings and Recommendations on Proposed Amendments to Title 18 Jefferson County Code (Unified
Development Code) Relating to Critical Areas
To Board of County Commissioners
The Planning Commission finds there is sufficient urban land as designated and zoned to
meet projected demand and need.
iv) Are any of the assumptions upon which the plan is based no longer found to be valid?
The Planning Commission finds that all assumptions in the Comprehensive Plan are still
valid.
V) Are there changes in the county -wide attitudes? Do they necessitate amendments to the
goals of the Comprehensive Plan and the basic values embodied within the Comprehensive
Plan Vision Statement?
The Planning Commission finds that the county -wide attitudes remain strongly aligned
with those embodied on the Comprehensive Plan Vision Statement. The proposal does
not necessitate amendments to the goals or basic values embodied within the
Comprehensive Plan Vision State and the proposal brings the development regulations
into better conformance with the Comprehensive Plan.
vi) Are there changes in circumstances which dictate a need for amendment to the
Comprehensive Plan?
The circumstances related to the proposal and/or area have not substantially
changed since the adoption of the Jefferson County Comprehensive Plan. The
Comprehensive Plan's periodic review and update was completed in December
2018; however, the CAO periodic review and update was postponed. This proposal
brings the CAO development regulations in alignment with the 2018
Comprehensive Plan.
vii) Do inconsistencies exist between the Comprehensive Plan and the GMA or the
Comprehensive Plan and the Countywide Planning Policies for Jefferson County?
The Planning Commission finds that there are no inconsistencies between the
Comprehensive Plan, GMA, and County -wide Planning Policies for Jefferson County.
III. Additional Findings from JCC 18.45.080(1)(c)(i-vii)

"Channel migration zone" (or CMZ) means an area within the lateral extent of likely stream
channel movement that is subject to risk due to stream bank destabilization, rapid stream incision,
stream bank erosion and shifts in the location of stream channels. "Channel migration zone"
means the historic channel migration zone (which is the footprint of the active channel
documented through historical photographs and maps), the avulsion hazard zone (which is an
area with the potential for movement of the main river channel into a new location), and the
erosion hazard area (which is an area outside the historic channel migration zone and the avulsion
hazard zone, and includes an erosion setback for a 100 -year period of time and a geotechnical
setback to account for slope retreat to a stable angle of repose). "Channel migration zone" does
not include disconnected migration areas, which are areas that have been disconnected from the

(1) Definitions. For the purposes of this section, the definitions in Chapter 9'? JCC shall apply.
(2) Agricultural Activities.
(a) Where Allowed. Agricultural activities, as defined above and excepting those related to
recreational marijuana/cannabis, are an allowed use under any of the Comprehensive Plan
land use designations, subject to the provisions of this subsection, except that "processing,"
"packing," and "sales" are regulated under subsection (3) (Accessory Uses). Agricultural
activities related to marijuana producing, processing and retail are subject to this section and
JCC 18.20.295 for recreational marijuana/cannabis. Where conflicts occur, the more
restrictive performance standards shall apply.
(b) When Exempt from Permit Process. Agricultural activities are considered a matter of right
and not subject to land use permits or approval from the administrator, except:
(i) Other Applicable Laws and Rules. This section does not exempt the proponent from
acquiring any other required approvals from county, state, or federal agencies, including,
but not limited to, approvals related to matters of public health, safety, and welfare.
(ii) Critical Areas Ordinance. If there is any conflict between this chapter and Chapter
18.22 JCC, the most protective requirement applies.
(iii) Stormwater Management. Jefferson County stormwater management regulations and
procedures are described in JCC 18.30.060, Grading and excavation standards, and

JCC 18.30.070, Stormwater management standards. These sections pertain to
agricultural activities in the following manner:
(A) Commercial agriculture is exempt from stormwater management minimum
standards pursuant to JCC 18.30.070(2) and the referenced Department of Ecology
Stormwater Management Manual for Western Washington (manual).
(B) According to the manual, "commercial agriculture" is defined as:
Those activities conducted on lands defined in RCW 84.34.020(2), and activities
involved in the production of crops or livestock for wholesale trade. An activity ceases
to be considered commercial agriculture when the area on which it is conducted is
proposed for conversion to a nonagricultural use or has Iain idle for more than five
years, unless the idle land is registered in a federal or state soils conservation
program, or unless the activity is maintenance of irrigation ditches, laterals, canals, or
drainage ditches related to an existing and ongoing agricultural activity.
(C) Accordingly, agricultural activities such as land preparation for the cultivation of
crops or the grazing of livestock and the maintenance of agricultural irrigation and
drainage infrastructure are exempt from meeting the minimum requirements for
stormwater management and from obtaining a stormwater management permit.
(D) This exemption does not apply to new development that is secondarily related to
agriculture and that involves the construction of new structures, such as buildings for
agricultural processing and retail sales, and the addition of impervious surfaces, such
as compacted areas designed to accommodate parking.
(E) This exemption does not apply to the initial clearing of forested land. Conversion
of forested land to some other use incompatible with commercial forestry, as defined
in the Forest Practices Act, Chapter 76.09 RCW, requires review under
JCC 18.20.160, 18.30.060 and 18.30.070. The State Department of Natural
Resources may also require a Class IV general forest practices application.
(iv) Farm Ponds and Irrigation Infrastructure.
(A) Construction or expansion of farm and stock ponds and irrigation ditches and
infrastructure in association with commercial agriculture as defined above is exempt
from meeting stormwater management minimum standards and from obtaining
approval; provided, these activities are not conducted in critical areas or critical area
buffers as defined in Chapter 18.22 JCC. Landowners are encouraged to document
the creation of new exempt ponds through photographs (before, during, and after
construction) in order to facilitate any future development review on the property.
(B) Generally, pursuant to JCC 18.30.060(5)(b), drainage improvements constructed
in accordance with JCC 18.30.060(2) and 18.30.070 and construction of a pond of
one-half acre or less which is not in a regulated wetland are exempt from the
stormwater management permit requirement outlined in JCC 18.30.070(5).

or approval is required by any other provision of the Jefferson County Code nevertheless are
subject to the requirements of this chapter.
(6) When any provision of this chapter is in conflict with any other section of the Jefferson County
Code, the provision that provides most protection to the critical area shall apply, except that any
critical area occurring within the jurisdiction of the Shoreline Management Act also shall follow the
policies and regulations in Chapter 18.25 JCC.
(7) Compliance with these regulations does not remove an applicant from the obligation to comply
with all other applicable federal, state, and/or local regulations.
(8) Any action taken in a critical area or a critical area buffer designated by this chapter that is in
violation of the standards and conditions contained in this chapter is expressly prohibited.

18.22.280 Adaptive Management.
Adaptive management relies on scientific methods to evaluate how well regulatory and
nonregulatory actions achieve their objectives and adjusts those programs. Management, policy,
and regulatory actions are treated as experiments that are purposefully monitored and evaluated
to determine whether they are effective and, if not, how they should be improved to increase their
effectiveness. An adaptive management program is a formal and deliberate scientific approach
to taking action and obtaining information in the face of uncertainty. To effectively implement an
adaptive management program, Jefferson County, in support of this chapter will:
(1) Address funding for the research component of the adaptive management program;
(2) Change course based on the results and interpretation of new information that resolves
uncertainties; and,
(3) Commit to the appropriate time frame and scale necessary to reliably evaluate regulatory and
nonregulatory actions affecting critical areas protection and anadromous fisheries.
Article III. Critical Aquifer Recharge Areas
18.22.300 Purpose
Potable water is an essential life-sustaining element for humans and many other species. Much of
Jefferson County's drinking water comes from groundwater supplies. Critical aquifer recharge areas
are important to ensure the quality and quantity of groundwater in aquifers. Preventing
contamination from land uses that may contaminate groundwater is necessary to protect water
supplies and avoid exorbitant costs, hardships and physical harm to people and ecosystems. It is
the purpose of this article to identify and classify aquifer recharge areas in accordance with WAC
365-190-100 and balance competing needs for land uses, clean water supplies and preserve
essential natural functions and processes, especially for maintaining critical fish and wildlife
habitat conservation areas.

18.22.310 Classification/designation.
Critical aquifer recharge areas are areas with a critical recharging effect on aquifers used for
potable water, including areas where an aquifer that is a source of drinking water is vulnerable to
contamination that would affect the potability of the water, or is susceptible to reduced recharge.
Critical areas aquifer recharge area maps shall be periodically revised, modified, and updated to
reflect current information.
The following classifications define critical aquifer recharge areas:
(1) Susceptible aquifer recharge areas. Susceptible aquifer recharge areas are those with
geologic and hydrologic conditions that promote rapid infiltration of recharge waters to
groundwater aquifers. For the purposes of this article, unless otherwise determined by preparation
of an aquifer recharge area report authorized under this article, the following geologic units, as
identified from available State of Washington Department of Natural Resources geologic
mapping, define susceptible aquifer recharge areas for east Jefferson County:
(a) Aluvial fans (Ha);
(b) Artificial fill (Hx);
(c) Beach sand and gravel (Hb);
(d) Dune sand (Hd);
(e) Floodplain alluvium (Hf);
(f) Vashon recessional outwash in deltas and alluvial fans (Vrd);
(g) Vashon recessional outwash in melt water channels (Vro);
(h) Vashon ice contact stratified drift (Vi);
(i) Vashon ablation till (Vat);
Q) Vashon advance outwash (Vao);
(k) Whidbey formation (Pw); and,
(1) Pre-Vashon stratified drift (Py).
(2) Special Aquifer Recharge Protection Areas. Special aquifer recharge protection areas include:
(a) Sole -source aquifers designated by the U.S. Environmental Protection Agency in
accordance with the Safe Drinking Water Act of 1974 (42 U.S.C. §300f et seq.), such as
Marrowstone Island;
(b) Special protection areas designated by the Washington Department of Ecology under
Chapter 173-200 WAC;
(c) Wellhead protection areas determined in accordance with delineation methodologies
specified by the Washington Department of Health under authority of Chapter 246-290 WAC;
Jefferson County Code DRAFT WORK PRODUCT
Chapter 18.22 CRITICAL AREAS SUBJECT TO REVIEW Page 31/109
EXHIBIT A
(d) Groundwater management areas designated by the Washington Department of Ecology
in cooperation with local government under Chapter 173-100 WAC.
(3) Seawater Intrusion Protection Zones (SIPZ).
(a) Seawater intrusion protection zones (SIPZ) are:
(i) Aquifers and land overlying aquifers with some degree of vulnerability to seawater
intrusion. SIPZ are defined either by proximity to marine shoreline or by proximity to
groundwater sources that have demonstrated high chloride readings.
(ii) All islands and land area within one-quarter mile of marine shorelines and associated
aquifers together compose the coastal SIPZ.
(b) High Risk SIPZ.
(i) Existing individual groundwater sources with a history of chloride analyses above 200
mg/L are categorized as a high risk SIPZ for development proposed under this code.
(ii) Areas within 1,000 feet of a groundwater source with a history of chloride analyses
above 200 milligrams per liter (mg/L) are categorized as a high risk SIPZ for development
proposed under this code.
(c) At Risk SIPZ. Areas within 1,000 feet of a groundwater source with a history of chloride
analyses above 100 milligrams per liter (mg/L) are categorized as at risk SIPZ for development
proposed under this code.
(d) Connate Seawater Exception. In some cases, high chloride readings may be indicative of
connate seawater (i.e., relic seawater in aquifers as opposed to active seawater intrusion). When
best available science or a hydrogeologic evaluation demonstrates that high chloride readings in
a particular area are due to connate seawater, the area in question shall not be considered an at
risk or high risk SIPZ.
(c) Recommendation from Public Health Department. When the status of an area as either a high
risk or an at risk SIPZ is in question, the administrator is responsible for making the determination
based upon recommendation from the Jefferson County Department of Public Health.
18.22.320 Applicability.
This article applies to any development within critical aquifer recharge areas, unless the proposed
activity meets any of the exemptions listed in JCC 18.22.230.

Article IV. Frequently Flooded Areas
18.22.400 Purpose
The purpose of this article is to protect the public health, safety and welfare from harm caused by
flooding and to establish protection standards for these areas. It is the intent of this article to
prevent damage and/or loss to both public and private property.
18.22.410 Classification/designation.
Frequently flooded areas are lands in the floodplain subject to at least a one percent or greater
chance of flooding in any given year, or within areas subject to flooding due to high groundwater.
These areas include, but are not limited to, streams, rivers, lakes, coastal areas, wetlands, and
areas where high groundwater forms ponds on the ground surface. Frequently flooded areas
perform important hydrologic functions and may present a risk to persons and property. Flood
hazard areas are depicted on the Federal Emergency Management Agency's Federal Insurance
Rate Maps (FIRMs). FIRMs display areas of concern including areas that fall within the 100 -year
flood plain designations of the Federal Emergency Management Agency and the National Flood
Insurance Program.
18.22.420 Applicability.
These standards apply to any development within frequently flooded areas, unless the proposed
activity meets any of the exemptions listed in Chapter 15.15 JCC. The flood damage prevention
ordinance (Chapter 15.15 JCC) conforms with the intent of the minimum guidelines (WAC 365-
190-1100)) through directly considering the effects of flooding on human health and safety,
together with effects on public facilities and services, through its protection standards. For
purposes of this article, development is defined as any man-made change to improved or
unimproved real estate, including but not limited to buildings or other structures, mining, dredging,
filling, grading, paving, excavation or drilling operations, storage of equipment or materials,
subdivision of land, removal of more than five percent of the native vegetation on the property, or
alteration of natural site characteristics.
18.22.430 Protection standards - Incorporation by reference of Chapter 15.15 JCC and
additional requirements.
This article incorporates by reference the classification, designation and protection provisions
contained in the Jefferson County flood damage prevention ordinance (Chapter 15.15 JCC) with
the following additions:
(1) Compliance with FIRMs. The FIRMs identified in the flood damage prevention ordinance
(Chapter 15.15 JCC) shall be used to determine flood hazard areas for compliance with the
Federal Emergency Management Agency (FEMA) regulatory requirements. Such flood hazard
areas shall be subject to the criteria of the flood damage prevention ordinance (Chapter 15.15
JCC).

(3) Compliance with National Marine Fisheries Service Biological Opinion.
Development proposed within regulated frequently flooded areas and floodplains shall ensure no
impacts to listed fish and wildlife habitat as required by the National Marine Fisheries Service
(NMFS) September 22, 2008 final Biological Opinion (BiOp) under the Endangered Species Act
(ESA) on the National Flood Insurance Program (NFIP) in Puget Sound (NMFS Tracking No.:
2006-00472 (or as amended by NMFS).
(4) 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 Perm it30;
(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.
Article V. Geologically Hazardous Areas
18.22.500 Purpose.
The purpose of this article is to reduce risks to human life and safety and reduce the risk of
damage to structures and property from geologic hazards, to allow for natural geologic processes
supportive of forming and maintaining fish and wildlife habitat, and to regulate and inform land
use and planning decisions. It is recognized that the elimination of all risk from geologic hazards
is not feasible to achieve but the purpose of this article is to reduce the risk to acceptable levels.

(1) Erosion and Landslide Hazard Development Standards.
(a) Development activities or actions requiring project permits or clearing shall not be allowed in
landslide hazard areas unless a aeotechnical report demonstrates that buildina within a landslide
hazard area will provide protection commensurate to being located outside the landslide hazard
area and meets the requirements of this section. This may include proposed mitigation measures.
(b) Top of Slope Building Setback. All development activities or actions that require project
permits or clearing in erosion and landslide hazard areas shall provide native vegetation from the
toe of the slope to twenty-five feet beyond the top of slope, with an additional minimum fifteen -foot
building and impervious surface setback, unless otherwise allowed through a geologic assessment.
The minimum building and setback shall be increased from the top of the slope as follows:
(i) For high landslide hazard areas, the setback shall be equal to the height of the slope (1:1
horizontal to vertical) plus the greater of one-third of the vertical slope height or twenty-five
feet.
(ii) For moderate landslide hazard areas, the setback shall be forty feet from the top of
slope•
(2) Toe of Slope Building Setback. A geotechnical report may be required based on slope height
and stability indicators. Where slope hazard indicators are not identified, the requirements of Title 15
JCC, will apply.
(3) The department may require a larger native vegetation width than the standard buffer distance
as determined above, if any of the following are identified through the geological assessment
process:
Jefferson County Code DRAFT WORK PRODUCT
Chapter 18.22 CRITICAL AREAS SUBJECT TO REVIEW Page 48/109
EXHIBIT A
(a) The adjacent land is susceptible to severe erosion and erosion control measures will not
effectively prevent adverse impacts; or
(b) The area has a severe risk of slope failure or downslope storm water drainage impacts.
(c) The minimum native vegetation width and/or building setback requirement may be
decreased if a geotechnical report demonstrates that a lesser distance, through design and
engineering solutions, will adequately protect both the proposed development and the
erosion or landslide hazard area. The department may decrease the setback when such a
setback would result in a greater than 1:1 slope setback.
Seismic Hazard Development Standards.
a) Development activities or actions reauirina a Droiect permit occurrina within two hundred feet
of a "high hazard" seismic hazard area may be allowed with an approved geotechnical report that
confirms the site is suitable for the proposed development and addresses any fill or grading that
has occurred on the subject parcel.
(b) Development activities or actions requiring a proiect permit within a seismic hazard area shall
be in accordance with Title 15 JCC.
(45) Reducing Buffer Widths. The administrator may reduce geologically hazardous area buffers
as follows:
(a) Buffers may be reduced by up to 25 percent with a geotechnical report prepared by a state
licensed geologist or licensed geotechnical engineer with a state stamp; provided, the
geotechnical report identifies recommendations for preventing or minimizing risks post -
development.
(b) All buffer reductions 25 percent or greater and all development within a high or moderate
geologically hazardous area shall require a geotechnical report prepared by a state licensed
geologist or licensed geotechnical engineer with a state stamp. The administrator may require
a third -party review based on JCC 18.22.930 or the applicant enters into an indemnity and
hold harmless agreement with the county that is approved by the county's risk manager and
the prosecuting attorney. If the administrator requires a third -party review of the geotechnical
report, the administrator shall be responsible for identifying and transmitting the geotechnical
report to the third -party reviewer.
(56) Increasing Buffer Widths. Buffer widths may be increased on a case-by-case basis, as
determined by the administrator, to protect the functions and values of a geologically hazardous

this determination, include but are not limited to:
(a) The landslide area is unstable and active.
(b) The adjacent land is susceptible to severe landslide or erosion, and erosion control
measures will not effectively protect the proposed project from the risks posed by the landslide
hazard area.
(c) The adjacent land has minimal vegetative cover.

(b) Developments that will not increase the threat to the health or safety of people and will not
increase potential for landslides on or off the site and meet the reasonable economic use
exception in JCC 18.22.260.
(c) Utility lines and pipes that are above ground, properly anchored and/or designed so that
they will continue to function in the event of a slope failure or movement of the underlying
materials and will not increase the risk or consequences of static or seismic slope instability
or result in a risk of mass wasting. Such utility lines may be permitted only when the applicant
demonstrates that no other feasible alternative is available to serve the affected population.
(d) Access roads and trails that are engineered and built to standards that minimize the need
for major repair or reconstruction beyond that which would be required in nonhazard areas.
Access roads and trails may be permitted only if the applicant demonstrates that no other
feasible alternative exists, including through the provisions of Chapter 8.24 RCW. If such
access through critical areas is granted, exceptions or deviations from technical standards for
width or other dimensions and specific construction standards to minimize impacts, including
drainage and drainage maintenance plans, may be required.
(e) Stormwater conveyance through a properly designed stormwater pipe when no other
storm -water conveyance alternative is available. The pipe shall be located above ground and
be properly anchored and/or designed so that it will continue to function in the event of a slope
failure or movement of the underlying materials and will not increase the risk or consequences
of static or seismic slope instability or result in increased risk of mass wasting activity.
(78) Seismic hazard areas — Standards. Development may be allowed in seismic hazard areas
when all of the following apply:
(a) The standards of JCC 18.22.530(1) shall apply.
(b) Structures in seismic hazard areas shall conform to applicable analysis and design criteria
of Chapter 18.15.05 JCC.
(c) Public roads, bridges, utilities, and trails shall be allowed when there are no feasible
alternative locations, and geotechnical analysis and design are provided that minimize
potential damage to roadway, bridge, and utility structures, and facilities will not be susceptible
to damage from seismically induced ground deformation. Mitigation measures shall be
designed in accordance with the most recent version of the American Association of State
Highway and Transportation Officials (AASHTO) Manual or another appropriate document.
() Tsunami hazard areas — Standards.
(a) The standards of JCC 18.22.530(1) shall apply.
(b) For development within tsunami hazard areas the proposed development shall be
designed to provide protection from the tsunami hazard that meets the projected hazard on
the Department of Natural Resources Tsunami Inundation Maps.

18.22.610 Classification/designation.
Fish and Wildlife Habitat Conservation Areas (FWHCAs) are areas that serve a critical role in
sustaining needed habitats and species for the functional integrity of the ecosystem, and which,
if altered, may reduce the likelihood that the species will persist over the long term. FWHCAs
include those areas identified as being of critical importance to the maintenance of endangered,
threatened, or sensitive species of fish, wildlife and/or plants, or designated habitats and species
of local importance.
(1) The following are designated as fish and wildlife habitat conservation areas
(a) Areas where federally listed species (endangered and threatened) and state -listed species
(endangered, threatened, and sensitive species) have a primary association.
(b) Rivers and streams not otherwise addressed under Washington State Forest Practices
regulations (Chapter 76.09 RCW and Title 222 WAC).
(c) Commercial and recreational shellfish areas.
(d) Kelp and eelgrass beds.
(e) Surf smelt, Pacific herring, and Pacific sand lance, and other forage fish spawning areas.
(f) Naturally occurring ponds less than 20 acres, including submerged aquatic beds that
provide fish and wildlife habitat.
(g) Lakes, ponds, streams, and rivers planted with game fish by a governmental or tribal entity.
(h) State natural area preserves, natural resource conservation areas, and state wildlife areas.
(i) Species and habitats of local importance designated pursuant to the process delineated in
Article IX (Special Reports).
(2) Designated fish and wildlife habitat conservation areas that are within shoreline jurisdiction
are regulated under the shoreline master program in Chapter 18.25 JCC, and in circumstances
where this chapter conflicts with the shoreline master program, the provisions of the shoreline
master program shall prevail.

(c) Bridge piers or abutments may be allowed either within the floodway or between the
ordinary high-water marks provided no other reasonable alternative placement exists;
(d) Crossings shall serve multiple properties whenever possible; and,
(e) Where there is no reasonable alternative to providing a culvert, the culvert shall be the
minimum length necessary to accommodate the permitted activity.
(2) Utilities. Placement of utilities within designated fish and wildlife habitat areas may be allowed
pursuant to the following standards:
(a) Construction of utilities may be permitted in FWHCAs when no practicable or reasonable
alternative location is available and the utility corridor does not cause or increase habitat
fragmentation for state or federally listed species and 47 meets the requirements for installation,
replacement of vegetation and maintenance outlined below. Utilities are encouraged to follow
existing or permitted roads where possible.
(b) Construction of sewer lines or on-site sewage systems may be permitted in FWHCA
buffers when it can be demonstrated that it is necessary to meet state and/or local health code
requirements; that there are no other practicable alternatives available; and, construction
meets the requirements of this article. Joint use of the sewer utility corridor by other utilities
may be allowed.
(c) New utility corridors shall not be allowed in FWHCAs with known locations of federal or
state -listed endangered, threatened, or sensitive species, except in those circumstances
where an approved habitat management plan is in place.

18.22.650 Habitat management reports —When required.
(1) When a development, use, or activity is proposed on lands designated as a fish and wildlife
habitat conservation area or a buffer, a habitat evaluation may be required. An on-site habitat
evaluation determines if FWHCAs or buffers occur in the project area.
(2) If the proposed use, development, or activity occurs in marine water, a dive survey shall be
required to determine if any FWHCA is present in the project area and if any FWHCA has the
potential to be affected by the proposal.
(3) Evaluations shall be conducted pursuant to the special report requirements found in Article IX
Special Reports.
(4) Types of Reports. When required by this section, an applicant shall submit a report
documenting the results of the habitat evaluation for county review and approval. Based on the
results of the site evaluation, a report shall be prepared by a qualified professional and either be:
(a) Habitat Reconnaissance Letter. This type of report shall be used if the field evaluation
determines that no regulated fish and wildlife habitat conservation area or buffer is present in
the proposed project area, which includes those areas that may be temporarily affected by
construction -related activities or would be within the limits of clearing for construction. Habitat
reconnaissance letters shall be prepared by a wildlife biologist based on requirements
presented in Article IX (special reports) of this chapter.
(b) Habitat Management Plan. This type of report shall be used if the field evaluation
determines that any portion of the proposed project occurs within a regulated FWHCA or

18.22.660 Mitigation
(1) Applicants shall prepare and submit a mitigation plan for FWHCA buffer reductions greater
than 25% but less than 50% and may submit a financially -bonded critical areas stewardship plan
for impacts to FWHCAs or for buffer reductions greater than 50 percent of the standard buffer
width; provided, the proposal meets the mitigation or critical area stewardship provisions of this
chapter.
(2) Sequencing.
The overall goal shall be no net loss of functions, natural processes, or area within a FWHCA or
a FWHCA buffer. All regulated development, uses, and activities in a FWHCA or an associated
buffer shall be mitigated in the following order:
(a) Avoiding the impact altogether by not taking a certain action or parts of an action;
(b) Minimizing adverse impacts by limiting the degree or magnitude of the action and its
implementation;
(c) Rectifying the adverse impact by repairing, rehabilitating, or restoring the affected
environment to the historical condition or the condition existing at the time of the initiation of a
project;
(d) Reducing or eliminating the adverse impact over time by preservation and maintenance
operation during the life of the action;
(e) Compensating for the adverse impact by replacing, enhancing, or providing substitute
resources or environments;
(f) Monitoring the required compensation and taking appropriate corrective measures when
necessary.
(2) Mitigation - Minimum requirements and types of mitigation.
(a) Minimum mitigation requirements are as follows:
(i) Unavoidable impacts to a critical area buffer shall be mitigated with at least a 1:1
mitigation ratio. The administrator has the authority to require buffer mitigation at a higher
ratio if the area to be adversely affected consists of intact native habitat.
(ii) Unavoidable impacts to a critical area shall require mitigation that fully compensates
for all adverse effects to FWHCA functions, natural processes, and area.
(b) FWHCAs mitigation shall include the following options:

(i) On-site Mitigation. The applicant may propose on-site mitigation if the mitigation
proposal compensates for the loss or degradation to existing habitat.
(ii) Off-site Mitigation. The applicant may propose off-site mitigation if:
(A) On-site mitigation is not feasible and the mitigation proposal compensates for the
loss or degradation of existing habitats and species; or,
(B) Off-site mitigation occurs within the same ecosystem to the maximum extent
practicable 52 and provides better protection of the FWHCA or a significant ecological
and functional improvement to the FWHCA; and,
(C) There is a willing landowner that accepts the proposed mitigation; and,
(D) A mitigation agreement/easement is recorded that specifies the individuals or
parties responsible for implementing, maintaining, and monitoring the mitigation area.
(c) In -Lieu Fee Mitigation (ILF). As an alternative to permittee -responsible mitigation, an in -lieu
fee program may be used to compensate for impacts or alterations to a fish and wildlife habitat
conservation area or a buffer, if an established in -lieu fee program is available for the project area.
Use of the in -lieu fee program to address impacts to fish and wildlife habitat conservation areas
and/or buffers shall adhere to the in -lieu mitigation requirements in JCC 18.22.350(5).
Article VII. Wetlands
18.22.700 Purpose
The purposes of this article are to:
(1) Recognize and protect the beneficial functions, values, and services performed by wetlands,
which include, but are not limited to, providing food, breeding, nesting and/or rearing habitat for
fish and wildlife; recharging and discharging groundwater; contributing to stream flow during low
flow periods; stabilizing stream banks and shorelines; storing storm and flood waters to reduce
flooding and erosion; and, improving water quality through biofiltration, adsorption, retention and
transformation of sediments, nutrients, and toxicants.
(2). Regulate land use to avoid adverse effects on wetlands and maintain the functions, services,
and values of freshwater and estuarine wetlands throughout Jefferson County.
(3) Establish review procedures for development proposals in and adjacent to wetlands.
(4) Establish minimum standards for identifying and delineating wetlands
18.22.710 Classification/designation.
Wetlands are those areas that are inundated or saturated by surface water or groundwater at a
frequency and duration sufficient to support, and that under normal circumstances do support, a
prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally

include swamps, marshes, bogs, and similar areas. Wetlands may include those artificial wetlands
intentionally created from nonwetland areas to mitigate conversion of wetlands.
Wetlands do not include those artificial wetlands intentionally created from nonwetland sites,
including, but not limited to, irrigation and drainage ditches, grass -lined swales, canals, detention
facilities, wastewater treatment facilities, farm ponds, and landscape amenities, or those wetlands
created after July 1, 1990, that were unintentionally created as a result of the construction of a
road, street, or highway.
(1) Wetland Delineation. Wetlands shall be delineated in accordance with the requirements of
RCW 36.70A.175. Unless otherwise provided for in this chapter, all areas within the county
determined to be wetlands in accordance with the U.S. Army Corps of Engineers Wetlands
Delineation Manual, 1987 Edition, and the Western Mountains, Valleys, and Coast Region
Supplement (Version 2.0), 2010 or as revised, are hereby designated critical areas and are
subject to the provisions of this article.
(2) Wetland Rating. Wetlands shall be rated based on categories that reflect the functions and
values of each wetland. Wetland categories shall be based on the criteria provided in the
Washington State Wetland Rating System for Western Washington, revised 2014, and as
amended thereafter, as determined using the appropriate rating forms and associated figures
contained in that publication. These categories are generally defined as follows:
(a)Category I. These wetlands are: (1) relatively undisturbed estuarine wetlands larger than one
acre; (2) wetlands of high conservation value that are identified by scientists of the Washington
Natural Heritage Program/DNR; (3) bogs; (4) mature and old-growth forested wetlands larger
than one acre; (5) wetlands in coastal lagoons; (6) wetlands that perform many functions well
(scoring a total of 23 or more points). These wetlands: (1) represent unique or rare wetland types;
(2) are more sensitive to disturbance than most wetlands; (3) are relatively undisturbed and
contain ecological attributes that are impossible to replace within a human lifetime; or, (4) provide
a high level of functions.
(b) Category II. These wetlands are: (1) estuarine wetlands smaller than one acre or disturbed
estuarine wetlands larger than one acre or (2) wetlands with a moderately high level of functions
(scoring between 20 and 22 points total).
(c) Category III. These wetlands are (1) those with moderate level of functions (scoring between
16 and 19 points total) or (2) those that can often be adequately replaced with a well-planned
mitigation project. Wetlands scoring between 16 and 19 point generally have been disturbed in
some ways and are often less diverse or more isolated from other natural resources in the
landscape than Category II wetlands.
(d) Category IV. These wetlands have the lowest levels of functions (scoring 15 or fewer total
points) and are often heavily disturbed. These wetlands likely could be replaced or improved in
some cases. Replacement cannot be guaranteed in any specific case. These wetlands may
provide some important functions, so they should be protected to some degree.

from the requirements of this article when all of the following criteria are met:
(a) The wetland does not provide significant breeding habitat for native amphibian species.
Breeding habitat is indicated by adequate and stable seasonal inundation, presence of thin -
stemmed emergent vegetation, and clean water;
(b) The wetland does not have unique characteristics that would be difficult to replace through
standard compensatory mitigation practices;
(c) The wetland is not located within a fish and wildlife habitat conservation area (FWHCA) or
a FWHCA buffer as defined in Article VI of this chapter, and is not integral to the maintenance
of habitat functions of an FWHCA;
(d) The wetland is not located within a floodplain;
(e) The wetland is not within the jurisdiction of the county shoreline master program;
(f) The wetland is not part of a mosaic of wetlands and uplands, as determined using the
guidance provided in the wetland rating system; and,
(g) The wetland does not score five or more points for habitat functions (based on the 2014
version of the Washington Department of Ecology Wetland Rating System, or as amended
by Washington Department of Ecology).
In addition, mitigation in the torm of enhancement or expansion of another part of the butter to
should be considered in order to offset any expansion of a nonconforming use or structure. 54
Wetlands less than one-tenth acre that meet the above criteria shall not be filled or otherwise
altered. This exemption does not allow for unmitigated alteration of wetland area or functions.
Alteration of any wetland, including wetlands less than one-tenth of an acre, shall require
mitigation.
(4) General. Application for a project on a parcel of real property containing a designated wetland
shall adhere to the requirements in this section.
(a) Types of Wetland Evaluations. An applicant submitting an application for a development,
use, or activity on lands determined to be wetland shall also submit, and have approved, a
wetland evaluation prepared based on results of an on-site field investigation conducted by a
qualified wetland professional using wetland delineation manuals specified in JCC 18.22.710.
The wetland evaluation shall be completed based on the following:
(i) Wetland Reconnaissance. This type of wetland assessment does not require flagging
of wetland boundaries or completing a wetland rating form. It shall be used if no regulated

areas within 300 feet of any proposed project component.
(ii) Wetland Delineation. This type of wetland assessment shall be used if any portion of
the proposed project is within 300 feet of a regulated wetland, including those areas that
may be temporarily affected by construction -related activities or are within the proposed
limits of clearing. The on-site wetland boundary shall be flagged in the field and flags shall
be numbered sequentially, and a wetland rating form shall be completed, as required by
JCC 18.22.300(2), for each wetland identified. A wetland delineation report shall be
prepared by the wetland specialist based on report requirements presented in Article VIII
(special reports) of this chapter.
(b) If the wetland is located off of the property involved in the project application and is
inaccessible, the best available information shall be used to determine the wetland boundary
and category.
18.22.720 Regulated activities.
Any land use or development activity shall be subject to the provisions of this Article VII, including,
but not limited to, the following activities that are directly undertaken or originate in a regulated
wetland, unless exempted under JCC 18.22.070:
(1) The removal, excavation, grading, or dredging of material of any kind, including the
construction of ponds and trails;
(2) The dumping or discharging of any material, or placement of any fill;
(3) The draining, flooding, or disturbing of the wetland water level or water table;
(4) The driving of pilings;
(5) The placing of anything that obstructs water movement, including but not limited to, surface
water flow, surface water runoff, or groundwater infiltration;
(6) The construction, reconstruction, or expansion of any structure;
(7) The destruction or alteration of wetland vegetation through clearing, harvesting, shading,
intentional burning, application of herbicides or pesticides, or planting of vegetation that would
alter existing wetland conditions;
(8) The alteration or modification of water quality and/or water quantity.
(9) The requirement for a wetland evaluation may be waived by the administrator for construction
of a single-family residence on an existing lot of record if DCD staff or a qualified wetland evaluator
determines that:
(a) Sufficient information exists for staff to estimate the boundaries of a wetland without a
delineation; and,

The following activities may be permitted in wetlands and/or wetland buffers as specified when all
reasonable measures have been taken to avoid adverse effects on wetland functions and values
as documented through an alternatives analysis, the amount and degree of alteration are limited
to the minimum needed to accomplish the project purpose, and compensatory mitigation is
provided for all adverse impacts to wetlands that cannot be avoided. To the maximum extent
practicable, impacts to buffers shall be minimized and any disturbed buffer areas shall be
immediately restored except as specifically allowed.
(1) Utility lines in Category II, III, and IV wetlands and their buffers and/or Category I wetland
buffers when no feasible conveyance alternative is available shall be designed and constructed
to minimize physical, hydrologic, and ecological impacts to the wetland, and meet all of the
following:
a. The utility line is located as far from the wetland edge and/or buffer as possible and in a
manner that minimizes disturbance of soils and vegetation.
b. Clearing, grading, and excavation activities are limited to the minimum necessary to
install the utility line and the area is restored following utility installation.
c Buried utility lines shall be constructed in a manner that prevents adverse impacts to
surface and subsurface drainage. This may include regrading to the approximate original
contour or the use of trench plugs or other devices as needed to maintain hydrology.
d. Best management practices are used in maintaining said utility corridors such that
maintenance activities do not expand the corridor further into the critical area.
(2) Public roads or bridges in Category II, III, and IV wetlands and their buffers and/or Category I
wetland buffers when no feasible alternative alignment is available and the road or bridge is
designed and constructed to minimize physical, hydrologic, and ecological impacts to the wetland,
including placement on elevated structures as an alternative to fill, where feasible.
(3) Access to private development sites may be permitted to cross Category II, III, or IV wetlands
or their buffers; provided there are no feasible alternative alignments and measures are taken to
maintain preconstruction hydrologic connectivity across the access road. Alternative access shall
be pursued to the maximum extent feasible, including through the provisions of
Chapter 8.24 RCW. Exceptions or deviations from technical standards for width or other
dimensions, and specific construction standards to minimize impacts may be specified, including
placement on elevated structures as an alternative to fill, if feasible.
(4) Low -impact, passive recreational activities may be constructed, such as pervious trails,
nonpermanent wildlife watching blinds, and scientific or educational activities, and sports fishing

or hunting; provided, construction is limited to the outer 592555 percent of the buffer. Trails within
buffers shall be designed to minimize impacts to the wetland and shall not include any impervious
surfaces and avoid removal of significant treesss
(5) Stormwater management within the buffers of only Category III and IV wetlands with habitat
scores of 3-4 pointsspAy, are allowed provided the management techniques follow published
guidelines for stormwater management in wetlands by the Department of Ecology57 and are
vegetation -lined swales designed for stormwater management or conveyance when topographic
restraints determine there are no other upland alternative locations. Swales used for detention
purposes may only be placed in the outer 25 percent of the buffer. Conveyance swales may be
placed through the buffer, if necessary.
(6) Wetland buffer widths.
(a) The standard buffer shall be based on a combination wetland category, habitat function score
(from the wetland rating form), and land use intensity. The intensity of the land use shall be
determined in accordance with the definitions as listed below unless the technical administrator
determines that a lesser level of impact is appropriate based on information provided by the
applicant demonstrating that the proposed land use will have a lesser impact on the wetland than
that contemplated under the buffer standard otherwise appropriate for the land use,
The administrator shall have the authority to require buffers from the edges of all wetlands, in
addition to the building setback in accordance with the following:
(b) Wetland buffers shall be established to protect the integrity, functions, and values of the
wetland. Wetland buffers shall be measured horizontally from a perpendicular line established by
the wetland boundary based on the base buffer width identified in Table 18.22.735(1). Buffers
shall not include areas that are functionally and effectively disconnected from the wetland by an
existing, legally established road or another substantial developed surface.
(c) The buffer standards required by this article presume the existence of a dense, multi -storied
native vegetation community in the buffer adequate to protect the wetland functions and values.
When a buffer lacks adequate vegetation, the technical administrator may increase the standard
buffer, require buffer planting or enhancement, and/or deny a proposal for buffer reduction or
buffer averaging.
(d) The standard buffer shall be based on a combination wetland category, habitat function score
(from the wetland rating form), and land use intensity. The intensity of the land use shall be
determined in accordance with the definitions found in this chapter unless the technical
administrator determines that a lesser level of impact is appropriate based on information
provided by the applicant demonstrating that the proposed land use will have a lesser impact on

the wetland than that contemplated under the buffer standard otherwise appropriate for the land
use.
(e) Standard buffer widths are shown in Table 18.22.730(1). However, for Category I or II
wetlands with "special characteristics" as determined and defined through the Washington State
Department of Ecology (2014) Wetland Rating System (including estuarine, coastal lagoons,
wetlands of high conservation value, bogs, forested, and interdunal wetlands), only buffers in the
highest habitat score (8 to 9) group are applied.
(i) The prescribed buffer widths are based the wetland category (1, 11, 111, IV) as determined by
the scoring results on the rating form for the wetland rating system; and, the expected level
of impact of the proposed adjacent land use.
"High intensity land use" means land use that includes the following uses or activities:
commercial, urban, industrial, institutional, retail sales, residential (more than one
unit/acre), high-intensity new agriculture (dairies, nurseries, greenhouses, raising and
harvesting crops requiring annual tilling, raising and maintaining animals), high-intensity
recreation (golf courses, ball fields), hobby farms, and Class IV special forest practices,
including the building of logging roads A High Intensity Land Use may become a
Moderate Intensity Land Use where Required Measures to Minimize Impacts in Table
18.22.730(1)(b) are made part of the proposal and where a buffer condition is well
vegetated per 18.22.730(8) criteria.
"Low intensity land use" means land use that includes the following uses or activities:
forestry (cutting of trees only), low intensity open space (such as passive recreation and
natural resources preservation), utility corridor without a maintenance road and little or no
vegetation management58 and unpaved trails. Low intensity uses incorporate features in
Table 18.22.730(1)(b) by the nature of their use.
"Moderate intensity land use" means land use that includes the following uses or
activities: residential (one unit/gross acre or less), moderate -intensity open space (parks),
moderate -intensity new agriculture (such as orchards and hay fields), utility corridor or
riaht-of-wav shared by several utilities and includina access/maintenance roads59 and
paved trails
The administrator may determine, on the basis of detailed information from the applicant about
the site conditions, scope, and intensity of the proposed development, that the proposed land
use will have a lesser level of impact on the wetland than indicated by similar land uses on the
list.

wetland boundary as marked in the field during delineation if required, or based upon site
investigation, aerial photographs, or LiDAR images.
(ii) Functionally isolated buffer areas will be subject to wetland evaluation to determine
protective functions such as whether or not the isolated buffer area is used by wildlife to
gain access to the wetland. In instances where substantial wildlife use is documented, the
area shall be retained as buffer despite being otherwise isolated or disconnected from the
wetland.
(iii) When a buffer is on a slope steeper than 30 percent, and/or lacks adequately dense
and diverse vegetation, the administrator may deny a proposal for buffer reduction or
buffer averaging.

(9) Averaging Buffer Widths. Upon submission of a wetland evaluation by a wetland specialist
that demonstrates a buffer reduction does not adversely affect the existing functions and values
of the wetland, the administrator shall have the authority to average wetland buffer widths on a
case-by-case basis; provided, all of the following shall apply:
(a) The buffer averaging does not have any adverse impact on the functions and values of the
wetland and provides greater protection of the wetland;
(b) The total area contained within the buffer after averaging is no less than that which would
be contained within the prescribed buffer, and the buffer boundary remains more or less
parallel to the wetland boundary;
(c) The most sensitive, or highest value, areas of the wetland have the widest buffer
dimensions, and the buffer boundary considers variations in slope, soils, or vegetation to
optimize the overall effectiveness of the buffer;
(d) The minimum buffer width is no less than 75 percent of the standard prescribed buffer
width;
(e) The buffer width was not already the subject of a buffer reduction; and,
(f) If area of buffer reduction is composed of native trees that are 8 inches in diameter at breast
height, the buffer reduction shall not be approved unless the area of buffer increase consists
of native trees of a similar size, age, density, and species composition as that in the area to
be reduced.
(10) Buffer reductions in excess of those allowed under buffer reductions or buffer averaging will
be subject to a variance under JCC 18.22.250 or a financially bonded critical areas stewardship
plan (CASP); provided, the proposal can meet all CASP financial and other provisions.
(11) Increasing Buffer Widths. Buffer widths may be increased on a case-by-case basis, as
determined by the administrator, to protect the functions and values of a wetland. Supporting
documents that may be used to support this determination, include but are not limited to:
(a) The wetland is used by, or has habitat features that could be used by, state or federally
listed threatened or endangered species;
(b) The wetland serves as nesting or foraging habitat for raptors or great blue herons;
(c) The area adjacent to the wetland is susceptible to erosion or landslide; or,
(d) The area adjacent to the wetland has minimal deep rooting, native vegetation and/or the
slopes are greater than 30 percent.
18.22.740 Mitigation.
The overall goal of mitigation shall be no net loss of wetland function, value, and area.

(1) Mitigation Sequence. Mitigation includes avoiding, minimizing, or compensating for adverse
impacts to regulated wetlands. When a proposed use or development activity poses potentially
significant adverse impacts to a regulated wetland, the preferred sequence of mitigation as
defined below shall be followed unless the applicant demonstrates that an overriding public
benefit would warrant an exception to this preferred sequence.
(a) Avoiding the impact altogether by not taking a certain action or parts of an action;
(b) Minimizing adverse impacts by limiting the degree or magnitude of the action and its
implementation;
(c) Rectifying the adverse impact by repairing, rehabilitating, or restoring the affected
environment to the historical condition or the condition existing at the time of the initiation of a
project;
(d) Reducing or eliminating the adverse impact over time by preservation and maintenance
operation during the life of the action;
(e) Compensating for the adverse impact by replacing, enhancing, or providing substitute
resources or environments;
(f) Monitoring the required compensation and taking appropriate corrective measures when
necessary.
(2) Compensatory Wetland Mitigation — General Requirements. As a condition of any permit or
other approval allowing alteration which results in the unavoidable loss or degradation of
regulated wetlands, or as an enforcement action pursuant to Chapter 18.50 JCC, compensatory
mitigation shall be required to offset impacts resulting from the actions of the applicant or any
code violator.
(a) Except persons exempt under this article, any person who alters or proposes to alter
regulated wetlands shall provide wetland mitigation that is equivalent to or larger than those
altered in order to compensate for wetland losses. Table 18.22.740(1) specifies the mitigation
ratios by category and type of mitigation that must be used for compensatory wetland
mitigation:

' These ratios assume that the rehabilitation or enhancement actions implemented represent the
average degree of improvement possible for the site. Proposals to implement more effective
rehabilitation or enhancement actions may result in a lower ratio, while less effective actions
may result in higher ratio. The distinction between rehabilitation and enhancement is not clear-
cut. Instead, rehabilitation and enhancement actions span a continuum. Proposals that fall within
the gray area between rehabilitation and enhancement will result in a ratio that lies between the

2 Wetlands with high conservation value, coastal lagoons, and bogs are considered irreplaceable
wetlands because they perform some functions that cannot be replaced through compensatory
mitigation. Impacts to such wetlands would therefore result in a net loss of some functions no
matter what kind of compensation is proposed.
Note: Each type of mitigation is defined in Chapter 18.10.130 under mitigation types.
Note: Wetland preservation may be approved by the administrator under limited circumstances
on a case-by-case basis if preservation requirements are met, as specified in Wetland Mitigation
in Washington State, Part 1: Agency Policies and Guidance, or as amended.
(b) Compensatory mitigation may also be determined using methods described in Calculating
Credits and Debits for Compensatory Mitigation in Wetlands of Western Washington: Final
Report (Washington State Department of Ecology Publication #10-06-011, or as amended);
provided, the mitigation is consistent with Table 18.22.740(1).
(c) Compensatory mitigation must follow an approved compensatory mitigation plan pursuant
to this article, with the replacement ratios as specified above.
(d) Compensatory mitigation must be conducted on property that will be protected and
managed to avoid further development or degradation. The applicant or code violator must
provide for long-term preservation of the compensation area. The administrator has the
authority to require the applicant record a notice to title to ensure protection.
(e) Compensatory wetland mitigation shall be designed to mimic natural wetland hydrologic
conditions, and shall not be used as a stormwater system to comply with Chapter 18.30 JCC.
(f) The applicant shall post a mitigation performance bond to ensure monitoring the site occurs
and contingency plans are implemented if the project fails to meet projected goals. Corrective
actions must be coordinated and approved by department of community development.
(4LJ) Compensatory Wetland Mitigation — Type, Location, and Timing.
(a) Mitigation is to be provided in the preferred order listed below. A lower order preference
shall not be approved unless a wetlands evaluation prepared by a wetlands specialist
documents to the satisfaction of the administrator that a higher preferred option is not
ecologically viable.
(i) Restoration (re-establishment or rehabilitation) is the preferred mitigation option;
Jefferson County Code DRAFT WORK PRODUCT
Chapter 18.22 CRITICAL AREAS SUBJECT TO REVIEW Page 80/109
EXHIBIT A
(ii) Creation (also referred to as establishment) may be approved if restoration is not an
ecologically viable option;
(iii) Enhancement may be approved if restoration or creation are not ecologically viable
options or may be required in the same buffer area when a use or structure is permitted
and encroaches into the same buffer 64
(iv) Preservation (also referred to as protection or maintenance) is the least preferred
mitigation option and shall be permitted only under limited circumstances when, based on
a report prepared by a wetlands specialist, the administrator determines that no other
option is ecologically viable.
(b) On-site compensation within the same sub -drainage basin is preferred. The administrator
may approve off-site compensation only if:
(i) A wetlands specialist documents that on-site mitigation is not feasible and that off-site
mitigation is ecologically preferable;
(ii) No reasonable opportunities exist on-site and within the same sub -drainage basin;
(iii) On-site mitigation would result in the loss of high-quality upland habitats;
(iv) Off-site mitigation has a greater likelihood of compensating for project -related impact;
(v) On-site compensation is not feasible due to hydrology, soils, waves, or other factors;
(vi) On-site compensation is not practical due to probable adverse impacts from
surrounding land uses; and,
(vii) Potential functions and values at the site of the proposed restoration are significantly
greater than the lost wetland functional values.
(c) Compensation outside of the sub -drainage basin may be approved by the administrator if
an in -lieu fee program is used.
(d) Construction of compensation projects must be timed to reduce impacts to existing wildlife
and flora. Construction must be timed to assure that grading and soil movement occurs during
the dry season. Planting of vegetation must be specifically timed to the needs of the target
species.
(e) Compensation must be completed prior to wetland destruction, where feasible
(6) In -lieu Fee (ILF) Program. An applicant may opt to use an ILF program to compensate for
impacts to aquatic resources (critical areas) and/or buffers based on criteria listed below. Use of
an ILF program transfers the responsibility of providing compensatory mitigation from the
applicant to an ILF program sponsor. The sponsoring organization is required to provide mitigation
that complies with all mitigation requirements of this chapter.

(a) The ILF program may be used by an applicant as a way to mitigate for project impacts if
the impacts to the critical area or buffer occur within an ILF program service area. If an impact
occurs outside of an ILF Program Service Area, an applicant may request that Jefferson
County investigate the possibility of using the ILF program as mitigation. The ILF program
sponsor is under no obligation to accept mitigation responsibilities for impacts outside an ILF
program service area.
(b) The applicant shall determine if there is a preference for using the ILF program over
permittee -responsible mitigation to compensate for unavoidable impacts. The county may
encourage an applicant to use the ILF program, but shall not require an applicant to use ILF
for mitigation.
(c) The administrator may approve an application using an ILF program for mitigation if the
ILF program sponsor accepts the mitigation responsibility. The sponsoring organization has
the right to deny the request if the sponsoring organization cannot fulfill all ILF program
mitigation requirements. If the sponsoring organization does not accept the mitigation
responsibility, the applicant shall be responsible for providing mitigation that complies with
this chapter. The administrator shall not approve a permit involving ILF mitigation until (1) the
applicant has purchased the appropriate number of credits from the sponsoring organization
and (2) the sponsoring organization has completed a statement of sale. Once the ILF
program sponsor completes the financial transaction with the applicant, the sponsor
becomes responsible for completing the mitigation effort to comply with Jefferson County
Code critical areas requirements and the applicable approved in -lieu fee program instrument.
Article XIII. Agriculture
18.22.800 Purpose and Intent.
(1) Jefferson County desires to encourage the conservation of productive agricultural lands and
to implement alternative means of protecting critical areas using conservation practices in this
Article. As allowed under WAC 365-196-830 (Protection of Critical Areas), both regulatory and
voluntary measures may be developed and used to prevent degradation of critical areas.
(2) The well-being of agricultural activities in Jefferson County depends in part on good quality
soil, water, air, and other natural resources. Agricultural operations that incorporate protection of
the environment, including critical areas and their buffers as defined by Title 18 JCC, are essential
to achieving this goal.
(3) Jefferson County offers agricultural producers two paths to achieve no net loss of critical areas
functions and values while supporting the viability of agriculture. These two paths are:
(a) A "prescriptive" approach is one in which standard buffer widths from streams, wetlands,
and ponds are established, which may offer a simpler yet stricter set of standards; or,
(b) A "performance" based approach where the producer works independently or with farm
assistance agencies to identify the resource concerns that are unique to the farm operation
and to implement practices best suited to address those concerns.
Jefferson County Code DRAFT WORK PRODUCT
Chapter 18.22 CRITICAL AREAS SUBJECT TO REVIEW Page 82/109
EXHIBIT A
(4) Jefferson County shall ensure monitoring and adaptive management processes are in place
to evaluate whether the application of performance-based approaches address resource
concerns identified in this article to the extent related to agricultural activities.
18.22.810 Resource Concerns.
Agricultural activities have the potential to create adverse impacts to critical areas. It is the
county's policy to minimize such impacts.
(1) Nutrient Pollution of Water. Agricultural activities without proper conservation practices may
contribute wastes or sediments into a natural or modified natural stream or wetlands.
(2) Nutrient and Farm Chemical Management. Without proper conservation practices, manure
could be carried into a stream, wetlands, or other waters of the state by any means. Farm
chemicals must be applied consistent with chemical container labels and all applicable federal
and state laws and regulations to avoid harm to streams, wetlands, and other fish and wildlife
habitat conservation areas.
(3) Soil Erosion and Sediment Control Management. Construction of roads used for agricultural
purposes, agricultural equipment operation, and ditch construction and maintenance should be
undertaken in such a manner as to avoid sediment contribution to streams.
(4) Operation and Maintenance of Agricultural Drainage Infrastructure. Maintenance and
operation of ditches should be designed to prevent maintenance problems, avoid blocking water
flow, ensure control of erosion, avoid sedimentation, protect water quality, and ensure stream
bank vegetation is protected or replanted.
(5) Riparian Management. Dense riparian vegetation along the water's edge will slow and protect
against flood flows; provide infiltration and filtering of pollutants; secure food and cover for fish,
birds, and wildlife; and, keep water cooler in summer. Existing riparian vegetation should be

(3) Monitoring Program Benchmarks and Outcomes:
(a) Water quality monitoring results shall be based on sampling data collected and analyzed
by Jefferson County department of public health or a designated partnering agency. To
comply with the no harm requirement for water quality, all parameters evaluated must remain
comparable (or improve) relative to established state standards. If any water quality parameter
shows a decline, the departments of community development and public health may require
on-site sampling of upstream and downstream water quality conditions to determine if
permitted activities that have been implemented have since affected water quality.
(b) Habitat ecology should remain comparable to the watershed conditions as documented by
agencies with expertise with no net loss of critical area functions and values compared to a
baseline as of the effective date of this ordinance (XXX). Additionally, indicators of habitat
conditions, such as (1) the percent cover of woody vegetation shall not result in a net
decrease; (2) the amount of habitat features such as snags, downed woody debris, and open
water habitats shall not result in a net decrease.
(c) In -stream fish habitat, wetland and riparian vegetation conditions should remain stable
or improve (based on assessments, reports, and online information published the Washington
Department of Fish and Wildlife or another state or federal agency with comparable expertise).

the exceedance is adversely affecting designated critical areas; and, a change in
regulations that are applicable areawide or countywide is needed to address the
exceedance. Modifications may also be made if monitoring indicates that less stringent
standards are appropriate based on best available science.
18.22.850 Compliance.
(1) Critical area protection is required for existing and ongoing agriculture as well as new
agriculture. All agricultural activities shall be conducted so as not to cause harm or degrade the
existing functions of critical areas and associated buffers.
(2) Agricultural activities are expected to meet the objectives and standards of this Article through
voluntary compliance. Agricultural operations shall cease to be in compliance with this article, and
a new or revised critical areas checklist and supporting documentation will be required consistent
with JCC 18.22.820, when the administrator determines that any of the following has occurred:
(a) When a producer fails to implement and maintain their conservation practices determined
to exist or be scheduled in a Type 1 or Type 2 review per JCC 18.22.820 properly and fully.
(b) When implementation of the conservation practices fails to protect critical areas. If so, a
new or revised critical areas checklist and schedule of conservation practices shall be required
per JCC 18.22.820 to protect the values and functions of critical areas at the benchmark
condition described in JCC 18.22.840 or a baseline established by the producer in
consultation with a farm assistance agency or qualified professional.
(c) When substantial changes in the agricultural activities of the farm or livestock operation
have occurred that render the current critical areas checklist and associated conservation
practices ineffective. Substantial changes that render a critical areas checklist and associated
conservation practices ineffective are those that:
(i) Degrade baseline critical area conditions for riparian and wetland areas that existed
when the plan was approved;
(ii) Result either in a direct discharge or substantial potential discharge of pollution to
surface or ground water; or,
(iii) The type of agricultural practices changes from Type 1 to Type 2, Type 2 to Type 3.
(d) When a new or revised critical areas checklist and supporting documentation is
required, and the producer has been so advised in writing and a reasonable amount of
time has passed without significant progress being made to develop said plan. Refusal or
inability to provide a new checklist within a reasonable period of time shall be sufficient
grounds to revoke the approved agricultural activity and require compliance with the
standard provisions of this chapter.
(3) When a producer denies the administrator reasonable access to the property for technical
assistance, monitoring, or compliance purposes, then the administrator shall document such

refusal of access and notify the producer of his/her findings. The producer shall be given an
opportunity to respond in writing to the findings of the administrator, propose a prompt alternative
access schedule, and to state any other issues that need to be addressed. Refusal or inability to
comply with an approved critical areas checklist and schedule of conservation practices within a
reasonable period of time shall be sufficient grounds to revoke said plan and require compliance
with the standard provisions of this chapter.
(4) If agricultural activities result in degradation of a critical area, the farmer shall be required to
either cease the agricultural activity that results in critical area degradation or prepare a critical
areas checklist and supporting documentation that demonstrates how farming activities will be
brought into compliance with critical area protection requirements. The critical areas checklist
shall be submitted to department of community development for review and approval. If the
administrator determines the proposed activities and conservation practices do not sufficiently
address critical areas degradation, a farm assistance agency or qualified professional shall
prepare a schedule of conservation practices. The proponent shall allow the County or farm
agency with expertise reasonable access to the parcel to determine that the scheduled
conservation practices are installed, and critical areas functions are not being degraded. If
compliance cannot be achieved, other enforcement action based on Chapter 18.50 shall be
required.
(5) A producer is responsible only for those conditions caused by agricultural activities conducted
by the producer and is not responsible for conditions that do not meet the standards of this article
resulting from actions of others or from natural conditions not related to the on-site agricultural
operations. Conditions resulting from unusual weather events (such as storm in excess of a 25 -
year, 24-hour storm) or other exceptional circumstances that are not the product of obvious
neglect are not the responsibility of the owner or operator.
18.22.760 Limited Public Disclosure.
(1) Producers that have a farm plan developed by State or Federal farm assistance agencies will
not be subject to public disclosure unless required by law or a court of competent jurisdiction;
(2) Provided, that the county will collect summary information related to the general location of a
farming enterprise, the nature of the farming activity, and the specific conservation management
practices to be implemented such as through a critical areas checklist per JCC 18.22.720. The
summary information shall be provided by the farm operator or his/her designee and shall be used
to document the basis for the county's approval of the proposal.
(3) The county will provide to the public via its website information regarding which farms have
approved Type 1 or Type 2 conservation practices per JCC 18.22.720 and the date of their
approval.
(4) Upon request, the county may provide a sample critical areas checklist, exclusive of site- or
property specific information, to give general guidance on the development of a conservation farm
plan.

When a project is located within a landslide -prone geologically hazardous area, the following
additional project submittal requirements shall apply:
(i) Erosion Control Information. An evaluation of the erosion potential on the site during
and after construction is required. The evaluation shall include recommendations for
mitigation, including retention of vegetative buffers and a revegetation program. The
geotechnical engineer shall provide a statement identifying buffer areas at the top or toe
of a slope based on geotechnical site constraints and the impacts of proposed construction
methods on the erosion potential of the slope.
(ii) Seismic Information. The geotechnical engineer shall submit a statement that the
design criteria consider the one -in -one -hundred -year seismic event (an earthquake
ground motion that has a forty percent probability of exceedance in fifty years).
Calculations of soil bearing capacity, general soil stability, and wall lateral earth pressures
shall be adjusted to reflect a one -in -one -hundred -year seismic event and the structural
plans for the project shall be reviewed by the geotechnical engineer for consistency with
these design criteria:
Analysis for the one -in -one -hundred -year seismic event shall be based on a
near -crustal event having an assumed magnitude of 6.5 and occurring directly
below the site. Based on regional studies performed by others, the department
will allow the use of the following minimum general values of horizontal peak
ground accelerations for this event:
a = 0.2g for fill, alluvial soils
a = 0.17g for till, firm glaciated soils
a = 0.15g for rock.
The appropriateness of the above accelerations shall be confirmed by the
geotechnical engineer based on the actual site characteristics. Reduction in
the above values may be considered when supported by the appropriate
analytical evidence. Slope stability, lateral pressures, and liquefaction of the
site shall be assessed by using subsurface soil, rock, and groundwater
conditions, as well as the seismic parameters discussed above.
(iii) Recommendations on Relative Site Stability. The geotechnical engineer shall make
recommendations as to which portions of the site are the least prone to instability and the
preferred location of the structure. The limits of any area proposed for grading activity shall
be identified.

addition, recommendations for temporary erosion control and shoring/mitigating measures
shall be provided. The technical analysis shall consist of plans showing mitigation
techniques and a technical memorandum from the geotechnical engineer.
(v) Revisions to Geotechnical Report. Further recommendations shall be provided by the
geotechnical engineer should there be additions or exceptions to the original
recommendations based on the plans, site conditions, or other supporting data. If the
geotechnical engineer who revises the plans and specifications is not the same engineer
who prepared the geotechnical report, the new engineer shall, in a letter to the department,
express his or her agreement or disagreement with the recommendations in the
geotechnical report and state whether the plans and specifications conform to his or her
recommendations.
(vi) Plan and Specification Review. The geotechnical engineer shall submit a statement
that, in his or her judgment, the plans and specifications (if prepared by others) conform
to the recommendations in the geotechnical report and that all portions of the site which

technical assistance from the Jefferson County conservation district, Washington Department of
Fish and Wildlife or the Washington Department of Ecology when reviewing CASPs.
(4) Applicability and Limitations. The following provisions define the applicability and limitations
of the CASP:
(a) CASPs may be used in any zoning designation if the provisions of this article can be met.
CASPs may not be used in the urban growth area if a buffer reduction implemented while
using transitional zoning (i.e., rural zoning designation prior to connection with a sewer
system) has the potential to preclude future density requirements. The overall goal of the
CASP is to maintain existing functions and values of the watershed and subbasin, while
addressing the needs and desires of the property owner.
(b) CASPs can be applied to properties one-quarter acre or larger.
(c) CASPs are only applicable to fish and wildlife habitat conservation areas and associated
buffers (Article VI) or wetlands and associated buffers (Article VII).
(d) CASPs must provide equal or greater protection of critical area functions and values than
the prescriptive standards of buffers and setbacks.
(e) CASPs will be administered as a Type I permit, per Chapter 18.40 JCC
(5) Implementation.
(a) A CASP permit is valid for the same timeframe as the underlying permit (e.g., building
permit, septic permit, shoreline permit). If the underlying permit does not have a specified
expiration date or if the CASP application is a standalone application, the CASP permit shall
be valid for three years from the date the CASP permit is issued. A CASP permit shall not be
considered valid beyond five years from the date the CASP permit is issued. If the underlying
permit remains valid beyond five years, the CASP permit shall be considered null and void.
Once the permit has expired, it shall not be renewed.
(b) The applicant shall record a notice title for any approved mitigation at the Auditor's Office
and shall post a mitigation performance bond with DCD. The administrator shall provide the
necessary paperwork to the applicants. Assuming the administrator does not need to
designate staff (or contract with other qualified professionals) to ensure that maintenance and
monitoring are completed as required by this section, the performance bond is to be refunded
to the applicant at the end of the specified monitoring period or when all performance
standards are met, whichever is greater. The CASP permit is a conditional approval and no
other permits (such as building, shoreline, septic) shall be approved until the applicant has
recorded the notice to title and posted the performance bond.
(6) As -built plan requirement. An as -built plan shall be prepared by a wetland specialist describing
the action taken to implement the CASP. This as -built plan shall include:
(a) A contour map describing final contours if grading is required;
(b) A quantitative description of the vegetation planted;

Chapter 18.22 CRITICAL AREAS
EXHIBIT A
DRAFT WORK PRODUCT
SUBJECT TO REVIEW Page 109/109
(c) Establishment of two or more permanent photo documentation stations with established
bearings and monuments to ensure that subsequent photographs depict the same landscape for
comparative purposes;
(d) Additional photographic documentation that shows the condition of mitigation area(s) once
CASP mitigation has been implemented;
(e) A site plan showing the location of the mitigation areas relative to the mitigation proposal as
presented in the approved CASP report and to the CASP permit conditions; and,
(f) Building final certificate of occupancy and/or septic final shall not be issued until the applicant
has submitted an as -built showing compliance with this article, the approved CASP report, and
all CASP permit conditions.
(7) Contingency Plan Requirement. A contingency plan is required describing how the CASP
might be modified if monitoring indicates a failure to meet the stated goals, or a need to modify
the goals because of events outside the landowner's control (e.g., damage associated with a
wildlife). For instance, if one of the planted species of vegetation proves ill adapted to the
environment and fails to survive or thrive to the extent needed to provide the intended function
then alternative species should be identified. In general, plans should initially plant at greater than
120 percent of the specified final density of shrubs and trees. The contingency plan should call
for either supplemental planting when the density falls below the prescribed final density or it could
call for the planting of alternate specie(s).
(8) Failure to submit required reports. Failure to submit a report required under this article shall
constitute a failure to comply with the terms of the permit.
(9) Performance Bond. The administrator shall authorize the use of the performance bond to
ensure maintenance and monitoring are completed to comply with permit conditions. In the event
the performance bond amount is insufficient to ensure compliance with the permit (or if activities
on the site have negatively affected the mitigation area(s), the failure to comply with CASP permit
conditions shall be processed by the administrator pursuant to Chapter 18.50 JCC (Enforcement).
(10) Waiver.
The administrator may waive portions of a critical area stewardship plan (CASP) if, in the
administrator's opinion, critical area functions and values will not be adversely affected by a
proposed activity.
(11) Recording of Approved CASP Required. An approved CASP must be recorded on the
property deed (recorded with the Jefferson County auditor) and must remain in effect unless
replaced by a new or updated CASP approved by the county.

(i) Have circumstances related to the proposed amendment and/or the area in which it is
located substantially changed since the adoption of the Jefferson County Comprehensive
Plan?
The circumstances related to the proposal and/or area have no substantially changes since the
adoption of the Jefferson County CoMprehensive Plan. The Comprehensive Plan's Periodic
Review and Update was completed in December 2018, however, the CAO periodic review and
update was postponed. This proposal brings the CAO development regulations in alignment
with the 2018 Comprehensive Plan.
(ii) Are the assumptions upon which the [2004] Jefferson County Comprehensive Plan is
based no longer valid; or is new information available, which was not considered during
the adoption process or any annual amendments to the Jefferson County Comprehensive
Plan?
New information is available which was not considered during the most recent periodic review
and update of the Comprehensive Plan. Specifically, additional best available science and
public engagement have resulted in new information which informs this proposal.
(iii) Does the proposed amendment reflect current, widely held values of the residents of
Jefferson County?
The nronosal reflects currently widelv held values. The nronosed CAO meets the
Comprehensive Plan, representing resident input in the Comprehensive Plan
Periodic Review and Update completed in 2018. See for example the following
Framework Goal: Framework Goal VI Environmental Conservation: Foster
environmental stewardship, preserve clean air and water, and protect fish and
wildlife habitat. Anticipate and respond to climate change with mitigation and
adaptation strategies. Further, a robust public participation process included a
diverse group of appointed stakeholders, including the Critical Areas Ordinance
Regulatory Reform Task Force, which met and delivered recommendations on
the CAO to the Planning Commission, the Planning_ Commission finds that the
proposal reflects currently widely held values.
(iv) Is growth and development as envisioned in the {2884}2018 Comprehensive Plan
occurring faster or slower than anticipated, or is it failing to materialize?
2020 Critical Areas Ordinance Periodic Review and Update
Page 3 of 6
There is not sufficient information since the December 2018 adoption of the Jefferson County
Comprehensive Plan to assess whether growth or development as envisioned is occurring faster of
slower than anticipated
(v) Has the capacity of the county to provide adequate services diminished or increased?
The capacity of the Cog= to provide adequate services has not diminished or increased
relating to this proposal.
(vi) Is there sufficient urban land, as designated and zoned to meet projected demand and
need?
There is sufficient urban land as designated and zoned to meet projected demand and
need.
(vii) Are any of these assumptions under which the plan is based no longer found to be
valid?
All assumptions in the Comprehensive Plan are still valid.
(viii) Are there changes in the county -wide attitudes? Do they necessitate amendments to
the goals of the Comprehensive Plan and the basic values embodied within the
Comprehensive Plan Vision Statement?
The county -wide attitudes remain strongly aligned with those embodied on the Comprehensive
Plan Vision Statement. The proposal does not necessitate amendments to the goals or basic values
embodied within the Comprehensive Plan Vision State and the proposal brings the development
regulations into better conformance with the Comprehensive Plan.
(ix) Are there changes in circumstances which dictate a need for amendment to the
Comprehensive Plan?
The circumstances related to the proposal and/or area have no substantially
changes since the adoption of the Jefferson County Comprehensive Plan. The
Comprehensive Plan's Periodic Review and Update was completed in December
2018, however, the CAO periodic review and update was postponed. This
proposal brings the CAO development regulations in alignment with the 2018
Comprehensive Plan.
