This chapter shall be known and may be cited as the city of Port Orchard's "critical areas ordinance" or
"CAO."
20.162.012 Purpose.
The purpose of this chapter is to implement the goals, policies, guidelines, and requirements of the city's
comprehensive plan and the Washington State Growth Management Act to protect critical areas, the
environment, human life, and property from harm and degradation in accordance with the Growth
Management Act through the application of best available science, as determined according to WAC
365-195-900 through 365-195-925 and RCW 36.70A.172, and in consultation with state and federal
agencies and other qualified professionals.
20.162.014 Applicability.
No person. company. agency, or applicant shall alter a critical area or buffer except as consistent with
the requirements of this Title.
Except as provided for otherwise herein, the provisions of this chapter shall apply to all persons and
agencies, public or private, engaging in land uses, building, and/or development activity in the city of
Port Orchard that requires city approval.
(1) Critical Areas Review. All uses, activities, and development in critical areas and their buffers.
whether on public or private property, shall comply with the requirements of this chapter. These
regulations apply to all uses and activities within areas or adjacent areas designated as regulated
critical areas and/or their buffers that are within 300 feet of a site unless identified as exempt in
Section 20.162.034. Regulated uses and activities include, but not limited to:
3
11108823.1 - 366922 - 0001
(a) Removing, excavating, disturbing, or dredging soil, sand, gravel, minerals, organic matter. or

buffer not otherwise exempt from the provisions of this chapter.
20.162.016 Relationship to other regulations.
(1) Nothing in this chapter in any way limits, or may be construed to limit, the authority of the city under
any other applicable law, nor in any way decreases the responsibility of the applicant to comply with all
other applicable local, state, and federal laws and regulations.
(2) These critical areas regulations shall apply as an overlay and in addition to land use, development,
building, and other regulations adopted by the city.
(3) When any provision of any other chapter of the POMC conflicts with this chapter or when the
provisions of this chapter are in conflict, that provision which provides more protection to
environmentally critical areas shall apply unless specifically provided otherwise in this chapter or unless
such provision conflicts with federal or state laws or regulations.
(4) Compliance with the provisions of this chapter does not constitute compliance with other federal,
state, and local regulations and permit requirements that may be required. The applicant is responsible
for complying with these all requirements, apart from the regulations established in this chapter.
(5) Where critical areas occur within the city's shoreline jurisdiction as established by the city's shoreline
master program (Chapter 20.164 POMC), they are regulated under the regulations and provisions of the
shoreline master program.
20.162.018 Inventory provisions.
4
11108823.1 - 366922 - 0001
(1) Not all critical areas in the City of Port Orchard are fully mapped. The approximate location and
extent of mapped critical areas within the city are shown on the maps adopted as part of this chapter,
and incorporated herein by this reference. These maps shall be used only as a general guide for the
assistance of the department and the public; for a specific development or use proposal, the type,
extent and boundaries shall be determined in the field by a qualified specialist or staff person according
to the requirements of this chapter. In the event of a conflict between a critical area location shown on
the city's maps and that of an on -site determination, the on -site determination shall apply.
(2) Future Inventory Provisions. The city will review map inventory information of all critical areas as it
becomes available or on an annual basis. Mapping will include critical areas that are identified through
site -specific analysis by local, state and federal agencies, tribal governments, site -specific environmental
reports and other sources.
20.162.020 Administration -ter
(1) The Community Development D4irector, or hi their authorized designee, shall administer and
interpret the provisions of this chapter, except as otherwise specifically provided. The director shall
determine whether building, development, platting, or alteration of vegetation, trees, or habitat is
subject to this chapter. The director may also consult with other city departments and state and federal
agencies as necessary to obtain additional technical and environmental review assistance. The director
is authorized to adopt such administrative rules and regulations as are necessary and appropriate to
implement the provisions of this chapter.
(2) This chapter is to be administered with flexibility and attention to site -specific characteristics. It is
not the intent of this chapter to make a parcel of property unusable by denying its owner reasonable
economic use of the property nor to prevent the provision of public facilities and services necessary to
support existing development.
(3) The approvals granted under this chapter shall be valid for the same time period as the underlying
permit (e.g., preliminary plat, building permit, etc.). If the underlying permit does not contain a specified
expiration date, then approvals granted under this chapter shall be valid for a period of three years from
the date of issue, unless a longer or shorter period is specified by the director or by
a development agreement authorized by Chapter 36.708 RCW and consistent with POMC Chapter 20.26.
(4) If an activity is subject to this chapter but is not subject to any established city permit or approval,
the proponent shall obtain written authorization from the director prior to commencement to ensure
compliance with this chapter. Such authorization shall be processed as a Type I land use decision
pursuant to Chapter 20.22 POMC.
(5) Nothing in this chapter in any way limits, or may be construed to limit, the authority of the city under
any other applicable law, nor in any way decreases the responsibility of the applicant to comply with all
other applicable local, state, and federal laws and regulations.
20.162.022 ApplieatienCritical Areas Review types.
11108823.1- 366922 - 0001
This chapter establishes two distinct critical areas review roccdurcsrocesses that apply to activities
regulated by this Title. , includintz but not limitcd to land disturbinz activities and development
activities. areas review shall be conducted in conjunction with the underlying permit application.
except as described in section 1 below, and shall not constitute a permit action. The two tvocsreview
processes of reviews are as follows:
1) Critical Areas Review and Verification Unrelated to an Underlvine Permit. An applicant ma
request verification of the presence. absence, or boundary of cone or more wetlands or a fish
and wildlife habitat conservation areas located on. or within 300 feet of. the subject property.
This request may be submitted independent of a development activity application and is not
subject to administrative appeal.
a. Submittal Requirements: Verification requests shall include all applicable critical area
reports and supporting documentation. as required under Article VIII.
b. Validity: An approved critical area verification is valid for five (5) years from the date of
issuance. Verification is limited to the delineation and/or boundary confirmation of
critical areas. Wetland ratings and habitat assessments are not valid for the approved
verification period.
(2) Critical Areas Review and Verification Related to an Underlying Permit. For land disturbing
activities and development activityies within or adjacent to a critical area. a critical areas review
shall be conducted to evaluate consistency with the standards and requirements of this Title.
This review shall be performed in conjunction with an underlying permit application (such as a
building permit. land disturbing activity permit. conditional use permit. etc.).
a. Submittal Requirements: The applicant shall submit applicable special reports and
documentation, as defined in Article VIII, sufficient to evaluate compliance with all
applicable critical areas regulations.
b. Review Process: The Department shall review the proposal in the context of the
underlying permit application (e.g.. Type I, II, or III) and issue a critical areas verification
as part of the permit review. The verification shall confirm whether the proposed
activity complies with the applicable provisions of this chapter and identify any required
conditions of approval.
c. Integration with Permit Decision: The critical areas verification shall be incorporated
into the decision on the underlying permit and shall not constitute a separate decision
or permit action. Any objection to a critical areas verification shall be submitted and
evaluated in accordance with the procedures applicable to the underlying permit
application, as provided in POMC 20.22.
20.162.0242 Application requirements —Generally.
(1) Where not otherwise required aAll applicants are encouraged to meet with the department prior to
submitting an application subject to this title. The purpose of this meeting is to discuss the city's zoning
and applicable critical area requirements, to review any conceptual site plans prepared by the applicant
[.
11108823.1 - 366922 - 0001
and to identify potential impacts and mitigation measures. Such conference shall be for the convenience
of the applicant and any recommendations shall not be binding on the applicant or the city.
(2) To cxpcditc thc �jypermit review process, thc community dcvclopmcnt department shall be thc
lead agcncydepartmcn on all work related to critical arcas. Development may be prohibited in a
proposed development activity site based on criteria set forth in this chapter; the applicant should first
determine whether this is the case before applying for permits from the department.
(3) Application for development oposals, reasonable use exceptions, or variances regulated by this
chapter, or for review of special environmental reports, shall be made with the department by the
property owner, lessee, contract purchaser, other person entitled to possession of the property, or by
an authorized agent.
(4) All site plan applications for development proposals subject to this chapter shall include a site plan
drawn to scale identifying locations of critical areas and any associated buffers, location of proposed
structures and activities, including clearing and grading and general topographic information as required
by the department. If the department determines that additional critical areas are found on the subject
property, the applicant shall amend the site plan to identify the location of the critical area.
(5) A fee in an amount established by the city's fee schcdulcCritical areas review and application fees,
established in the city's fee resolution, shall be paid at the time an application for a permit relating to a
critical area or a special report review is filed. (Ord. 019-17 § 18 (Exh. 1)).
(6) Application Procedures for regulated uses and activities. Any regulated use or activities containing a
regulated critical area or its buffer, or within 300 feet of a critical area, shall provide the applicable
special reports, as defined in Article VIII and required by the department, prior to any development
authorization by the city. If an environmentally sensitive area is within 300 feet of the parcel but not on
the parcel, every effort should be made to obtain the required information. These efforts may include,
but are not limited to, visually assessing the feature from publicly accessible areas and utilizing available
databases to obtain the required information to prepare any applicable special reports. The department
may require additional reports or information to further identify potential impacts to any part of the
environment which may include the following:
(a) Erosion and sedimentation control measures and/or a stormwater or land disturbing activity
permit as required by the city's stormwater management regulations.
20.162.0264 Application requirements — Mitigation sequencing:
(1) Mitigation sequencing. Applicants shall demonstrate that all reasonable efforts have been examined
with the intent to avoid and minimize impacts to critical areas. When alteration to a critical area or
modification to its buffer is proposed, such alteration shall be avoided, minimized, or compensated in
the following order of preference:
(a) Avoiding the impact altogether by not taking a certain action or parts of an action;
7
11108823.1 - 366922 - 0001
(b) Minimizing impacts by limiting the degree or magnitude of the action and its implementation by
using appropriate technology or by taking affirmative steps, such as project redesign, relocation, or
timing, to avoid or reduce impacts;
(c) Rectifying the impact by repairing, rehabilitating, or restoring the affected environment to the
conditions existing at the time of the initiation of the project;
(d) Reducing or eliminating the impact over time by preservation and maintenance operations
during the life of the action;
(e) Compensating for the impact by replacing, enhancing, or providing substitute resources or
environments; and
(f) Monitoring the impact and the compensation project and taking appropriate corrective measures
when necessary. Monitoring shall occur for a minimum of five years. or until the department
determines that the mitigation project has achieved success. Certain types of habitat communities
require additional time for establishment and may require monitoring for 10 or more years
depending on the site -specific circumstances and the scope of the mitigation project.
(2) Mitigation measures may be required to address potential impacts that are identified through the
sequencing listed above. Mitigation shall be consistent with the requirements of Articic XII of
chapter.
20.162.0286 General mitigation requirements.
Unless otherwise provided in this chapter, if alteration to a critical area or its buffer is unavoidable, all
adverse impacts resulting from a development proposal or alteration shall be mitigated using the best
available science so as to result in no net loss of critical area functions and values, as provided below.
(1) In making a determination as to whether such a requirement will be imposed, and if so, the degree
to which it would be required, the director shall consider the following:
(a) The long-term and short-term effects of the action and the reversible or irreversible nature of
the impairment to or loss of the critical area;
(b) The location, size. and type of and benefit provided by the original and altered critical area;
c) The effect the proposed work may have upon any remaining critical area or associated aquatic
systems;
d) The cost and likely success of the compensation measures in relation to the magnitude of the
proposed project:
(e) The observed or predicted trend with regard to the gains or losses of the specific type of critical
area: and
8
11108823.1 - 366922 - 0001
(f) The extent to which the applicant has demonstrated a good faith effort to incorporate measures
to minimize and avoid impacts within the project.
(2) Mitigation projects shall not result in adverse impacts to adjacent property owners.
(3) Mitigation shall be in kind and on site, when possible. and sufficient to maintain the functions and
values of the critical area.
(4) Mitigation shall not be implemented until after permit approval of the director and shall be in
accordance with all reports and representations made therein.
5) Mitigation Sequencing. When an alteration to a critical area or its buffer js proposed, an applicant
shall sufficiently demonstrate mitigation sequencing as defined in POMC -20.162.026.
6) Mitigation for Lost or Affected Functions. Compensatory mitigation shall address the functions
affected by the proposed project or alteration to achieve functional equivalency or improvement and
shall provide similar critical area or buffer functions as those lost, except when:
(a) The lost critical area or buffer provides minimal functions as determined by a site -specific
functional assessment, and the proposed compensatory mitigation action(s) will provide equal or
greater functions or will provide functions shown to be limiting within a watershed through the
a propriate analysis: or
(b) Out of kind replacement of critical area type or functions will best meet watershed goals formally
identified by the city, such as placement of historically diminished critica1.
7) Type and Location of Mitigation. Unless it is demonstrated that a higher level of ecological
functioning would result from an alternative approach or required under Article III of this chapter.
compensatory mitigation for ecological functions shall be either in kind and on site, or in kind and within
the same subbasin, basin, watershed. or service area of a certified mitigation bank. Mitigation actions
shall be conducted within the same sub -drainage basin and on the site of the alteration except when all
of the following apply:
(a) There are no reasonable on -site or in subdrainage basin opportunities (e.g.. on -site options
would require elimination of high functioning upland habitat), or on -site and in subdrainage basin
o portunities do not have a high likelihood of success based on a determination of the natural
capacity of the site to compensate for impacts. Considerations should include: anticipated
mitigation ratios for the identified critical area(s), buffer conditions and proposed widths, available
water to maintain anticipated hvdrogeomorphic classes of wetlands. or streams when restored.
proposed flood storage capacity, potential to mitigate riparian fish and wildlife impacts (such as
connectivity):
b) Off -site mitigation has a greater likelihood of providing equal or improved critical area functions
than the impacted critical area; and
11108823.1 - 366922 - 0001
c) Off -site locations shall be in the same sub -drainage basin unless established -watershed goals for
water quality, flood storage or conveyance, habitat, or other functions have been established by the city
and strongly justify location of mitigation at another site.
(8) Mitigation Banks.
(a) Credits from a mitigation bank may be approved for use as compensation for unavoidable
impacts to critical areas when:
(i) The bank is certified under state rules:
(ii) The director determines that the mitigation bank provides appropriate compensation for the
authorized impacts; and
(iii) The proposed use of credits shall be consistent with terms and conditions of the bank's
certification.
(b) Replacement ratios for projects using bank credits shall be consistent with replacement ratios
specified in the bank's certification.
(c) Credits from a certified mitigation bank may be used to compensate for impacts located within
the service area specified in the bank's certification. In some cases, the service area of the bank may
include portions of more than one adiaccnt drainage basin for specific habitat functions.
(9) In -Lieu Fee. Credits from an approved in -lieu fee program may be used when all of the following
apply:
(a) The approval authority determines that the use of the program would provide environmentally
appropriate compensation for the proposed impacts:
(b) The proposed use of credits is consistent with the terms and conditions of the approved in -lieu
fee program instrument:
c) Projects using in -lieu fee credits shall have debits associated with the proposed impacts
calculated by the applicant's qualified specialist using the credit assessment method specified in the
a proved instrument of the in -lieu fee program: and
(d) The impacts are located within the service area specified in the approved in -lieu fee program
instrument.
(10) Timing of Compensatory Mitigation. It is preferred that compensation projects will be completed
prior to activities that will disturb the on -site critical area. If not completed prior to disturbance.
compensatory mitigation shall be completed immediately following the disturbance and prior to the
issuance of final certificate of occupancy. Construction of mitigation projects shall be timed to reduce
impacts to existing fisheries, wildlife, and flora. The director may authorize a one-time temporary delay
in completing construction or installation of the compensatory mitigation when the applicant provides a
10
11108823.1 - 366922 - 0001
written explanation from a qualified professional as to the rationale for the delay (i.e.. seasonal planting
requirements. fisheries window).
(11) Critical Area and Buffer Enhancement as Mitigation. Impacts to critical area or buffer functions may
be mitigated by enhancement of existing significantly degraded critical area or buffers, but should be
used in conjunction with restoration and/or creation where possible. Applicants proposing to enhance
critical areas or their buffers must include in a report how the enhancement will increase the functions
of the degraded critical area or buffer and how this increase will adequately mitigate for the loss of
critical area and function at the impact site. An enhancement proposal must also show whether any
existing critical area functions will be reduced by the enhancement action.
20.162.0302r8 Application requirements — Review criteria.
(1) Applications for any development proposal subject to the critical areas ordinance shall be reviewed
by the director or designee for completeness and consistency or inconsitcncy with this chapter.
(2) The director may withhold, condition, or deny land use, building, and/or development permits or
activity approvals to ensure that the proposed action is consistent with this chapter. In evaluating a
request for a development proposal regulated by this chapter, it shall be the responsibility of the
director to determine the following:
(a) The nature and type of critical area and the adequacy of any special reports required in
applicable sections of this chapter;
(b) Whether the development proposal is consistent with this chapter, by granting, denying, or
conditioning projects;
(c) Whether proposed alterations to critical areas are appropriate under the standards contained in
this chapter, or whether it is necessary for the applicant to seek a variance or other exception; and
(d) If the protection mechanisms and the mitigation and monitoring plans and bonding measures
proposed by the applicant are sufficient to protect the public health, safety and welfare consistent
with the purpose and regulations contained in this chapter, and if so, condition the permit or
approval accordingly.
(3) At every stage of the application process, the burden of demonstrating that any proposed
development is consistent with this chapter is upon the applicant.
20.162.0"0320 Bonds.
Mitigation required pursuant to a development proposal must be completed prior to the City's granting
of final approval of the development proposal. If the applicant demonstrates that seasonal
requirements or other circumstances beyond its control prevent completion of the mitigation prior to
final approval, the City may permit the applicant to post a performance bond or other security
instrument in a form and amount deemed acceptable by the Director, which guarantees that all
11
11108823.1 - 366922 - 0001
required mitigation measures will be completed no later than the time established by the department in
accordance with this chapter.
(1) All bonds and acceptable securities guaranteeing compliance with this chapter shall be set in the
amount of 150 percent of the averagc expected value of the project. The value of theproiect and
subsequent bond shall be based on the engineer's estimate, subject to the City's approval, of the subject
work. If thc applicant and dircctor do not agrcc to thc cnginccr's cstimatc, then the bond shall be based
on thc average of thrcc contract bids that establish all costs of compensation, including costs relative to
performance, monitoring, maintenance, and provision for contingency plans.
(2) Performance Bonds. Except for public agencies, applicants receiving a land use, development, or
building permit or approval subject to the provisions of this chapter are required to post a cash
performance bond or other acceptable security to guarantee compliance with this chapter prior to
beginning any site work. The surety shall guarantee that work and materials used in construction are
free from defects. All performance surety or bonds shall be reviewed and approved by the city attorney
and recorded upon execution. The performance surety or bonds cannot be terminated or canceled
without written approval. The director shall release the bond after documented proof that all structures
and improvements have been shown to meet the requirements of this chapter and that a maintenance
bond has been posted, if required.
(3) Maintenance Bonds. Except for public agencies, an applicant shall be required to post a cash
maintenance bond or other acceptable security guaranteeing that structures and improvements
required by this chapter will perform satisfactorily for a minimum of three years after they have been
constructed and approved. All bonds shall be on a form approved by the city attorney. Without written
release, the bond cannot be canceled or terminated. The director shall release the bond after
determination that the performance standards established for measuring the effectiveness and success
of the project have been met.
4. Monitoring Bonds. For projects that require ongoing monitoring in accordance with this chapter.
applicants shall provide a maintenance/monitoring bond or other security instrument in a form and
amount determined sufficient by the Department to guarantee satisfactory workmanship. materials.
and performance of structures and improvements allowed or required by this Title for a period up to ten
(10) years. unless otherwise specified. The duration of maintenance/monitoring obligations, including
financial guarantees, shall be established by the Director after consideration of the nature of the
proposed mitigation and likelihood and expense of correcting mitigation failures.
20.162.990342 Notice to title.
The director shall require an applicant to file a "Ceritical Aarea and Bbuffer NRotice to Ttitle" on a form
approved by the Ceity with the Kitsap County Aauditor for all properties included in land use and
development proposals subject to the provisions of this chapter and containing critical areas and/or
their buffers. Such notice shall be a covenant that runs with the land in perpetuity and include
identification of the boundaries of the critical areas and/or their buffers and any permanent conditions
imposed by the ^City. The covenant shall be recorded prior to the issuance of any permit or at the time a
short plat, Unit Lot Subdivision, or final plat is recorded. This notice shall serve as an official notice to
subsequent landowners that the land ewne landowner is responsible for complying with existing
12
11108823.1 - 366922 - 0001
conditions for development or use as established by this chapter and any city, state, or federal permits
or other approvals, and shall accept sole responsibility for any risk associated with the land's identified
critical area.
20.162.0320364 Exemptions.
(1) An exemption means that an activity is fully exempt from critical areas review and not subject to the

do not have a surface outlet by which water leaves the wetland, even seasonally, to another water
body. Isolated wetlands can also be sloped wetlands where surface water, if present, reenters the
shallow groundwater zone at the base of the wetland and is not linked via surface flows to a
downstream water body. Any project involving filling or altering a wetland that meets this definition of
isolated wetland is subject to regulation by the State Department of Ecology under the Water Pollution
Control Act (Chapter 90.48 RCW), in addition to the provisions in this chapter. An isolated wetland may
also be regulated by the U.S. Army Corps of Engineers under the Clean Water Act. Dredge or fill of a

Article Ill. Wetlands
20.162.046050 Wetlands — Purpose.
This article applies to all regulated uses within or adjacent to areas designated as wetlands, as
categorized below. The intent of this article is to:
(1) Achieve no net loss and increase the quality and function of wetland acreage, functions and values
within the city.
(2) Provide mitigation measures where necessary, as conditions of permits, that have a reasonable
expectation of success.
(3) Protect t4evalued public expenditures resources that could arise from improper wetland uses and
activities;
(5) Preserve natural flood control, stormwater storage and drainage orstream swetland hydrology
patterns; and
(6) Prevent turbidity and pollution of wetlands, and fish or shellfish bearing waters to maintain the
wildlife habitat.
20.162.0520 Determination of wetland boundaries.
33
11108823.1 - 366922 - 0001
1) The determination of the wetland edge or boundary shall be done in accordance with the delineation
methodology specified in the approved federal wetland delineation manual and applicable regional
supplements. All areas within the city meeting the wetland designation criteria as determined by that
procedure are designated as critical areas and are subject to the provisions and regulations of this
chapter. Wetland delineations are valid for five years.
2) The applicant shall be responsible for hiring a qualified wetland specialist to determine the wetland
boundaries through a field survey. This specialist shall stake or flag the wetland boundary. For all new
development, as required by the department, this line shall be surveyed by a professional land surveyor
licensed in the state of Washington. The regulated wetland boundary and regulated wetland buffer shall
be identified on all grading, landscaping, site. on -site septic system designs (BSAs). utility or other
development plans submitted in support of the project.
3) Where the applicant has provided a delineation of a wetland boundary. the department or its
consultant may verify the wetland boundary at the cost of the applicant and may request that
adjustments to the boundary be made by a wetland specialist. (Ord. 019-17 § 18 (Exh. 1)).
20.162.0542 Wetland categories.
-2-)-The City uses the Department of Ecology's Washington State Wetland Rating System for Western
Washington: 2014 Update -Version 2 (Ecology Publication No. 23-06-009). or as amended hereafter to
categorize wetlands for the purposes of establishing wetland buffer widths, wetland uses and
replacement ratios for wetlands. This system consists of four wetland categories (see Article XIII of this
chapter, Attachment A, for wetland categories).
20.162.9690564 Exempt wetlands.
(1) All wetlands within the Ccity meeting the definition in POMC 20.162.0486 are regulated. The
following wetlands may be exempt from the requirement to avoid i ^ar*avoidance and minimization
requirements of mitigation sequencing, and they may be filled if the impacts are fully mitigated based
on the requirements of this chapter. If available, impacts should be mitigated through the purchase of
credits from an in -lieu fee program or mitigation bank, consistent with the terms and conditions of the
program or bank.
34
11108823.1 - 366922 - 0001
The following wetlands meeting the criteria defined below may be exempt from the standard wetland
buffer requirements defined in this chapter. A building or impervious surface setback of 15 feet is
required from the edge of any wetland meeting the criteria defined below.
In order to verify the following conditions, a critical area report for wetlands meeting the requirements
of this chapter must be submitted.
(a) All isolated Category IV wetlands less than 4,000 square feet that:
(i) Are not associated with riparian areas or their buffers.
(ii) Are not associated with shorelines of the state or their associated buffers.
(iii) Are not part of a wetland mosaic.
(iv) Do not score five or more points for habitat function based on the Washington State Wetland
Rating System for Western Washington: 2014 Update -Version 2 (Ecology Publication No. 23-06-
0092014 Update (Ecology Publication No. ,1 O6 029, or as revised as approved by Ecology).
(v) Do not contain a priority habitat or a priority area for a priority species identified by the
Washington Department of Fish and Wildlife, do not contain federally listed species or their critical
habitat, or species of local importance.
(b) Wetlands less than 1,000 square feet that meet the above criteria and do not contain federally
listed species or their critical habitat are exempt from the buffer provisions contained in this
chapter.
20.162.058.2 Wetland d9evelopment standards.
For the purpose of the provisions of the critical areas ordinance, a regulated wetland and its buffer is a
critical area.
(1) Unless specifically exempt under POMC 20.162.036. all regulated uses and activities in a wetland
and/or its buffer shall be regulated pursuant to the requirements of this chapter.
(2) Wetland Buffers. The buffer shall be measured perpendicular from the wetland edge as delineated
and marked using the approved federal delineation manual and applicable regional supplement. Buffers
shall consist of native vegetation adequate to provide the necessary protection. Where required and
35
11108823.1 - 366922 - 0001
conditioned as part of permit approval, the City may require Tthose buffer areas that do not contain a
well -vegetated native plant community &Iaft-to be enhanced. Exccpt through ^x^mption, ^xccption or
variance, buffcrs shall remain undisturbed natural vcgctation areas except whcrc thc buffer can bc
enhanced to improve its functional attributes. Any buffer enhancement and/or limited view clearing
activity must bc reviewed and approved by the department. No refuse shall bc placed in the buffer.
(3) Buffer Widths. All regulated wetlands shall be surrounded by a buffer zone as follows based on the
category of wetland and the habitat score as determined by a qualified wetland professional using the
Washington State Wetland Rating System for Western Washington2014 Update -Version 2 (Ecology
Publication No. 23-06-009 or as amended: 2014 Update (i accordance with Department f Ecology
Publication Ne 14 06 029).)j
(a) For wetlands that score six points or more for habitat function, the buffers in Table 1 can be used if
both of the following criteria are met:
(i) A relatively undisturbed, vegetated corridor at least 100 feet wide is protected between the
wetland and any other priority habitats as defined by the Washington State Department of Fish and
Wildlife. The corridor must be protected for the entire distance between the wetland and the
priority habitat by some type of legal protection such as a conservation easement. Presence or
absence of a nearby habitat must be confirmed by a qualified biologist. If no option for providing a
corridor is available, Table 1 may be used with the required measures in Table 2 alone.
(ii) The measures in Table 2 are implemented, where applicable, to minimize the impacts of the
adjacent land uses.
(b) For wetlands that score three to five habitat points, only the measures in Table 2 are required for
the use of Table 1.
(c) If an applicant chooses not to apply the mitigation measures in Table 2, or is unable to provide a
protected corridor where available, then Table 3 must be used.
(d) The buffer widths in Table 1 and Table 3 assume that the buffer is vegetated with a native plant
community appropriate for the ecoregion. If the existing buffer is unvegetated, sparsely vegetated,
or vegetated with invasive species that do not perform needed functions, the buffer should either
be planted to create the appropriate plant community or the buffer should be widened to ensure
that adequate functions of the buffer are provided.
{e(e) Reduced buffer widths associated with Table 1 shall not be used in conjunction with other
reductions or variances outlined in this chapter.
j) Interrupted Buffer. Where a legally established developed roadway or permanent substantial
improvement transects a wetland buffer, the director may approve a modification of the minimum
required buffer to the edge of the roadway or substantial improvement. The permanent substantial
development must serve to eliminate or greatly reduce buffer function.

(6§) Wetland Buffer Alterations
A quantitative alteration, in which the boundaries of the wetland buffer area are altered, can occur
through buffer averaging or through a buffer reduction. Buffer averaging shall not be used in
conjunction with a buffer reduction.
The buffers defined in Table 1 are considered an administrative buffer reduction and shall not be used in
conjunction with a proposed wetland buffer alteration.
Wetland Buffer Averaging. Standard buffer widths may be modified by averaging buffer widths. The
total area contained within the buffer after averaging shall be no less than that contained within the
standard buffer prior to averaging. The buffer shall not be reduced by more than 25 percent of the
standard buffer width at any point. The department may allow wetland buffer averaging where it
can be demonstrated that such averaging can clearly provide equivalent or greater functions and
values as would be provided under the standard buffer requirement.
41
11108823.1 - 366922 - 0001
Prior to approval of buffer averaging, a critical areas report for wetland(s) meeting the requirements in
this chapter must be submitted and reviewed for consistency with the requirements of this Chapter.
Averaging of buffer widths may be allowed where the applicant demonstrates the following:
(i) The buffer is increased adjacent to higher functioning areas of or more sensitive portions of the
wetland and decreased adjacent to the lower function or less sensitive portions; and
(ii) Averaging is necessary to avoid an extraordinary hardship to the applicant caused by
circumstances peculiar to the property and the applicant has demonstrated all avoidance and
minimization measures have been considered.
(b) Wetland Buffer Reduction. Buffer width reductions shall be considered on a case -by -case basis when
an applicant demonstrates to the department that the mitigation measures outlined in Table 2 are
not applicable to utilize the reduced buffer widths defined in Table 1 and the proposed reduction
would not adversely affect the wetland in question. A buffer reduction may not be reduced to less
than 75 percent of the standard buffer width.
Decision Criteria. Prior to approval. an applicant shall demonstrate that a buffer reduction proposal
meets all of the decision criteria listed below.
i) Demonstrate all avoidance and minimization efforts have been considered for compliance with
POMC 20.162.024:
(ii) It will not adversely impact the wetland(s) in question:
(iii) It will not lead to adverse water quality protection, unstable earth conditions, or create an
erosion hazard:
(iv) As part of the buffer reduction request, an applicant shall submit a buffer enhancement plan
consistent with Article VIII of this Chapter.
(7b) Increased Wetland Buffer Provisions. The department may increase buffer zone widths for a
development project on a case -by -case basis when a larger buffer is necessary to protect wetland
functions and values. Such determination shall be based on site -specific and project related conditions,
which include, but are not limited to:
(a) Wetland sites with known locations of endangered or threatened species for which a habitat
management plan indicates a larger buffer is necessary to protect habitat values for such species;
(b) The adjacent land is susceptible to severe erosion and erosion control measures alone will not
effectively prevent adverse wetland impacts;
(c) The adjacent land on the development proposal site has minimal vegetative cover or slopes greater
than 30 percent; or
42
11108823.1 - 366922 - 0001
(8-7) Wetland Fencing and Signs. This subsection applies to those wetlands and their buffers that are
within 300 feet of regulated development activities.
(a) Wetland buffers shall be temporarily fenced or otherwise suitably marked, as required by the
department, between the area where the construction activity occurs and the buffer. Fences shall be
made of a durable protective barrier and shall be highly visible. Silt fences and plastic construction
fences may be used to prevent encroachment on wetlands or their buffers by construction. Temporary
fencing shall be removed after the site work has been completed and the site is fully stabilized per city
approval.
(b) The department shall require permanent signs and/or split -rail fencing to be placed on the common
boundary between a wetland buffer and the adjacent land. Signs must be posted at an interval of one
per lot if the lot is less than 50 feet wide, or every 50 feet, whichever is less, and must be maintained by
the property owner in perpetuity. The signs shall be worded as follows or with alternative language
approved by the department:
Protected Wetland Area
Do Not Disturb
Contact City of Port Orchard
Regarding Uses, Restrictions, and Opportunities for Stewardship
The department may approve an alternate method of wetland and buffer identification, if the
alternative method provides adequate protection to the wetland and buffer.
(98) Building or Hard Surface Setback Lines. A building or hard surface setback line of 15 feet is required
from the edge of any wetland buffer. Minor structural or hard surface intrusions into the areas of the
setback may be permitted if the department determines that such intrusions will not adversely impact
the wetland. The setback shall be identified on a site plan and filed as an attachment to the notice to
title as required by POMC 20 16203003220.162.034, Notice to title.
20.162.0-5606068 Additional development standards for regulated uses.
In addition to meeting the development standards in this article, those regulated uses identified below
shall also comply with the standards of this section and other applicable state, federal and local
ordinances.
•
•-
43
11108823.1- 366922 - 0001
-2(1) Agricultural Restrictions. In all development proposals which would permit introduction of
agricultural uses, damage to regulated wetlands shall be avoided. Wetlands shall be avoided by one of
the following methods:
(a) Implementation of a farm conservation plan agreed upon by the conservation district and the
applicant to protect and enhance the water quality of the wetland; and/or
(b) Fencing located not closer than the outer buffer edge.
-4j2) Land Divisions and Land Use Permits. All proposed divisions of land and land uses (including but not
limited to the following: boundary or lot line adjustments, short plats, large lot subdivisions, master
planned resorts, planned residential developments, conditional use permits, site plan reviews, binding
site plans) which include regulated wetlands shall comply with the following procedures and
development standards:
(a) Regulated wetlands, except the area with permanent open water, and wetland buffers may be
included in the calculation of minimum lot area for proposed lots; provided, that other standards,
including subsection (§3)(c) of this section, are met.
(b) Land division approvals shall be conditioned to require that regulated wetlands and regulated
wetland buffers be dedicated as open space tracts, or an easement or covenant encumbering the
Lot with the wetland and wetland buffer. Such dedication, easement or covenant shall be recorded
together with the land division and represented on the final plat, short plat or binding site plan, and
title.
sirerI' .. y ,!y.ia.
ir-
(d) After preliminary approval and prior to final land division approval, the department shall require
the common boundary between a regulated wetland or associated buffer and the adjacent land be
identified using permanent signs and/or fencing. In lieu of signs and/or fencing, alternative methods
44
11108823.1 - 366922 - 0001
of wetland and buffer identification may be approved when such methods are determined by the
department to provide adequate protection to the wetland and buffer.
(§3) Stormwater Management Facilities. A wetland or its buffer can be physically or hydrologically
altered to meet the requirements of an LID, runoff treatment or flow control BMP if all of the following
criteria are met:
(a) The wetland is classified as a Category IV or a Category III wetland with a habitat score of 3 to 45
points; and
(b) There will be "no net loss" of functions and values of the wetland; and
(c) The wetland does not contain a breeding population of any native amphibian species; and
(d) The hydrologic functions of the wetland can be improved as outlined in questions 3, 4, 5 of Chart
4 and questions 2, 3, 4 of Chart 5 in the Department of Ecology's "Guide for Selecting Mitigation
Sites Using a Watershed Approach"; or the wetland is part of a priority restoration plan that
achieves restoration goals identified in a shoreline master program or other local or regional
watershed plan; and
(e) The wetland lies in the natural routing of the runoff, and the discharge follows the natural
routing; and
(f) All regulations regarding stormwater and wetland management are followed, including but not
limited to local and state wetland and stormwater codes, manuals, and permits; and
(g) Modifications that alter the structure of a wetland or its soils will require permits. Existing
functions and values that are lost would have to be compensated/replaced.
Stormwater LID BMPs required as part of new and redevelopment projects can be considered within
wetlands and their buffers. A site -specific characterization is required to determine if an LID BMP is
feasible at the project site.
(-GA wetland hydrology monitoring plan prepared by a qualified wetland specialist shall be required
when a wetland is physically or hydrologically altered. The plan shall provide an analysis to demonstrate
the baseline hydrologic conditions within the wetland, provide monitoring methods. provide a
monitoring program to evaluate the hydrologic conditions post construction, and provide a reporting
schedule for submitting monitoring reports to the city. The wetland hydrology monitoring plan shall be
verified through City review.
(4) Trails and Trail -Related Facilities. Construction of public and private trails and trail -related facilities,
such as benches and viewing platforms, may be allowed in wetlands or wetland buffers pursuant to the
following guidelines:
(a) Trails and related facilities shall, to the extent feasible, be placed on existing road grades, utility
corridors, or any other previously disturbed areas.
45
11108823.1 - 366922 - 0001
(b) Trails and related facilities shall be planned to minimize removal of trees, soil disturbance and
existing hydrological characteristics, shrubs, snags and important wildlife habitat.
(c) Viewing platforms and benches, and access to them, shall be designed and located to minimize
disturbance of wildlife habitat and/or critical characteristics of the affected wetland.
(d) Trails and related facilities shall generally be located outside required buffers. Where trails are
permitted within buffers they shall be located in the outer 25 percent of the buffer and a minimum
of 25 feet from the wetland edge, except where wetland crossings or viewing areas have been
approved.
(e) Trails shall generally be limited to pedestrian use and pervious surfaces, such as loose gravel or
bark chip, and are no more than five feet in width, unless other more intensive uses, such as bike or
horse trails, have been specifically allowed and mitigation has been provided.
(f) Circular (loop) trails are discouraged, as they have the potential to encircle critical areas and cut
off habitat connectivity for smaller species.
(75) Utilities in Wetlands or Wetland Buffers.
(a) Construction of new utilities outside the road right-of-way or existing utility corridors may be
permitted in wetlands or wetland buffers, only when no reasonable alternative location is available
and the utility corridor meets the requirements for installation, replacement of vegetation and
maintenance outlined below, and as required in the filing and approval of applicable permits and
special reports required by this chapter.
(b) Sewer or On -Site Sewage Utility. Construction of sewer lines or on -site sewage systems may be
permitted in regulated wetland buffers only when:
(i) The applicant demonstrates it is necessary to meet state and/or local health code minimum
design standards (not requiring a variance for either horizontal setback or vertical separation):
and/or
(ii) There are no other practicable or reasonable alternatives available and construction
epee sThe applicant sufficiently demonstrates the mitigation sequencing requirements efdefined in
this sectie+nChapter show all avoidance and minimization measures have been considered. Joint use
of the sewer utility corridor by other utilities may be allowed. Special use review according to the
requirements of this chapter will be required when such activities occur in wetland buffers.
(c) New utility corridors shall not be allowed when the regulated wetland or buffer has known
locations of federal or state listed endangered, threatened or sensitive species, heron rookeries or
nesting sites of raptors which are listed as state candidate or state monitor, except in those
circumstances where an approved habitat management plan indicates that the utility corridor will
not significantly impact the wetland or wetland buffer.
46
11108823.1- 366922 - 0001
(d) New utility corridor construction and maintenance shall protect the regulated wetland and
buffer environment by utilizing the following methods:
(i) New utility corridors shall be aligned when possible, to avoid cutting trees greater than 12
inches in diameter at breast height (four and one-half feet), measured on the uphill side.
(ii) New utility corridors shall be revegetated with appropriate native vegetation at
preconstruction densities or greater, immediately upon completion of construction, or as soon
thereafter as possible, if due to seasonal growing constraints. The utility shall ensure that such
vegetation survives.
(iii) Any additional utility corridor access for maintenance shall be provided as much as possible
at specific points, rather than by parallel roads. If parallel roads are necessary, they shall be of a
minimum width but no greater than 15 feet; and shall be contiguous to the location of the utility
corridor on the side away from the wetland. Mitigation will be required for any additional access
through restoration of vegetation in disturbed areas.
(iv) The department may require other additional mitigation measures.
(e) Utility corridor maintenance shall include the following measures to protect the regulated
wetland and buffer environment:
(i) Where feasible, painting of utility equipment such as power towers shall not be sprayed or
sandblasted, nor should lead -based paints be used.
(ii) No pesticides, herbicides or fertilizers may be used in wetland areas or their buffers except those
approved by the EPA and Ecology. Where approved, herbicides must be applied by a licensed
applicator in accordance with the safe application practices on the label. Within wetlands, the
applicator must be licensed to use aquatic herbicides.
(f) For utility work in wetlands or in -water, it shall be the applicant's responsibility to obtain all
necessary state and federal approvals before beginning work.

(1) Mitigation Sequence. Projects permitted under this article will be reviewed in accordance with the
mitigation sequencing requirement in POMC 20.162.10402420.162404026.
(2) Mitigation Plan Requirements. Any applicant required to perform compensatory wetland mitigation
as a condition of approval for a development project or under an enforcement action shall submit a
wetlands mitigation plan to the department in accordance with POMC 20.1 62.096 and
20.' x04.20.162.028 and 20.162.096. Compensatory mitigation plans shall be consistent with
Wetland Mitigation in Washington State — Part 2: Developing Mitigation Plans — Version 1 (Ecology
Publication No. 06-06-011b or as revised), and Selecting Wetland Mitigation Sites Using a Watershed
Approach (Western Washington) (Ecology Publication No. 09-06-32), and with amended Appendix 8-C to
Wetlands in Washington State Volume 2 — Protecting and Managing Wetlands (Ecology Publication 05-
06-008 or as revised).
(3) Wetland Replacement Ratios. The following ratios, as well as consideration of the factors listed in
this section, and Table 4, shall be used to determine the appropriate amounts of restored, rehabilitated,
created, or enhanced wetland that will be required to replace impacted wetlands. The first number
specifies the amount of wetland area requiring replacement and the second specifies the amount of
wetland area altered.

(a) Open water may be enhanced by replacing structures that may have been removed in the past
(large woody material, rocks, reefs, etc.).
(b) The department may increase the ratios based on one or more of the following:
(i) The probable success of the proposed restoration or enhancement;
(ii) The period of time between destruction and replication of wetland functions;
(iii) Projected losses in functions and value;
(iv) Replacement as a result of an illegal action.
(4) -Alternative Mitigation Ratios. The department may approve different mitigation ratios when the
applicant proposes a combination of wetland creation, restoration, rehabilitation, and/or enhancement;
provided, that federal and state resource agencies approve the mitigation plan and the plan achieves no
net loss of wetland functions and values. Mitigation requirements may also be determined using the
credit/debit tool described in Calculating Credits and Debits for Compensatory Mitigation in Wetlands of
Western Washington: Final Report (Ecology Publication No. 10-06-011, or as revised) if approved by the
director.
{§ 5) Type and Location of Mitigation.
A plicants have two options for meeting compensatory wetland mitigation requirements defined in this
chapter. The options generally fall into two categories: programmatic approaches and permittee-
responsible approaches. Programmatic approaches refer to compensatory mitigation done by a third -
party sponsor. The two programmatic approaches currently being used in Washington are wetland
49
11108823.1 - 366922 - 0001
mitigation banking and in -lieu fee mitigation. Permittee-responsible mitigation is an approach where
the applicant retains full responsibility to successfully compensate for unavoidable impacts. The order
of preference for the type of mitigation approaches is a programmatic approach followed by a
permittee-responsible approach.
(a) Wetland Mitigation Banks. Credits from a wetland mitigation bank may be approved for use as
compensation for unavoidable impacts to wetlands when:
(i) The bank is certified under state and/or federal rule:
(ii) The director determines that the wetland mitigation bank provides appropriate compensation
for the authorized impacts:
(iii) The proposed use of credits shall be consistent with the terms and conditions of the mitigation
bank's certification:
(iv) Replacement ratios for project using bank credits shall be consistent with the replacement ratios
specified in the mitigation bank's certification: and
(v) Credits from a certified wetland mitigation bank may be used to compensate for impacts located
within the service area specified in the wetland bank's certification. In some cases, the service area
of the bank may include portions of more than adjacent drainage basin for specific wetland
functions.
(b) In -Lieu Fee. Credits from an approved in -lieu fee program may be used when all of the following
apply:
(i) The approval authority determines that the use of the program would provide environmentally
arDiDroDriate compensation for the proposed impacts;
(ii) The proposed use of credits is consistent with the terms and conditions of the approved in -lieu
fee program instrument:
(iii) Projects using in -lieu fee credits shall have debits associated with the proposed impacts
calculated by the applicant's qualified specialist using the credit assessment method specified in the
a proved instrument of the in -lieu fee program: and
(iv) The impacts are located within the service area specified in the approved in -lieu fee program
instrument.
(c) Mitigation under the watershed approach. When it is demonstrated that a programmatic
approach is not available to compensate for unavoidable impacts to wetlands, compensatory
wetland mitigation shall use the water shed approach using the guidance defined in the Department
of Ecology's Selecting Wetland Mitigation Sites Using a Watershed Approach (Western Washington)
(Ecology Publication No. 09-06-321. or as amended.
50
11108823.1 - 366922 - 0001
(d) Alternative Mitigation. The department may approve an alternative mitigation plan based on
best available science and if is demonstrated that a high level of ecological function would result
from an in -kind and on -site or in -kind and off -site compensatory wetland mitigation approach.
Alternative mitigation proposals shall use the guidance in the Department of Ecology's Wetland
Mitigation in Washington State — Part 2: Developing Mitigation Plans — Version 1 (Ecology
Publication No. 06-06-011b), or as revised.
(e) Innovative Mitigation. The Director may approve innovative mitigation projects that are based on
best available science including but not limited to activities such as advance mitigation and
preferred environmental alternatives. Innovative mitigation proposals must offer an equivalent or
better level of protection of critical area functions and values than would be provided by the strict
application of this chapter. Such mitigation proposals must demonstrate special consideration for
conservation and protection measures for anadromous fisheries. The Director shall consider the
following for approval of an innovative mitigation proposal:
i). Creation or enhancement of a larger system of natural areas and open space is preferable to the
preservation of many individual habitat areas:
(ii). The applicant demonstrates that long-term protection and management of the habitat area will
be provided;
(iii). There is clear potential for success of the proposed mitigation at the proposed mitigation site:
(iv). Mitigation according to POMC 20.162.062 5(a) through 5(d) is not feasible due to site
constraints such as parcel size. stream type. wetland category, or excessive costs:
(v). A wetland of a different type is justified based on regional needs or functions and values:
vi). The replacement ratios are not reduced or eliminated: unless the reduction results in a
preferred environmental alternative; and
(vii). Public entity cooperative preservation agreements such as conservation easements are
applied.
L6) Monitoring Requirements. The city shall require monitoring reports on an annual basis for a
minimum of five years, or until the department determines that the mitigation project has achieved
success. Certain types of wetland communities, such as scrub -shrub or forested wetland, require
additional time for establishment and may require monitoring for 10 or more years depending on
the site -specific circumstances and the scope of the mitigation project. The wetlands mitigation plan
shall provide specific criteria for monitoring the mitigation project. Criteria shall be project -specific
and a scientifically acceptable means to aid the department in evaluating whether or not the project
has achieved success according to the wetland mitigation performance standards in this chapter.

51
11108823.1 - 366922 - 0001
The eCity of Port Orchard recognizes that property owners wish to gain economic benefits from their
land. The Ceity encourages such mechanisms as the open space tax program, conservation easements
and donations to land trusts, in order to provide taxation relief upon compliance with the regulations in
the provisions of the critical areas ordinance. (Ord. 019-17 § 18 (Exh. 1)).
Article IV. Fish and Wildlife Habitat Conservation Areas
20.162.0680664 Purpose.
This article applies to all regulated uses included in the critical areas ordinance, or uses within 300 feet
of areas designated as fish and wildlife habitat conservation areas, as categorized in POMC
20.162.07006620.162.068. The intent of this article is to:
(1) Preserve natural flood control, stormwater storage and drainage or stream flow patterns;
(2) Control siltation, protect nutrient reserves and maintain stream flows and stream quality for fish,_
wildlife, and marine shellfish;
(3) Prevent turbidity and pollution of streams and fish or shellfish bearing waters;
(4) Preserve and protect habitat adequate to support viable populations of native wildlife in both the
city and Kitsap County; and
(5) Encourage nonregulatory methods of habitat retention whenever practical, through education and
the open space tax program.
20.162.07-90686 Fish and wildlife habitat conservation area categories classification.
The following categories shall be used in classifying fish and wildlife habitat conservation areas. Fish and
wildlife habitat conservation areas that are located within the city's shoreline jurisdiction according to
the city's shoreline master program are regulated through the provisions of this chapter.
(1) Streams. All streams which meet the criteria for Type Fes, Np , Ns}4and 5 waters as set forth in the
DNR water rating system- as defined in WAC 222-16-030 (see Table 5).
(2) Lakes Less Than 20 Acres in Surface Area. Those lakes which meet the criteria for Type 2, 3, 4 and 5
waters as set forth in WAC 222-16-030, as now or hereafter amended. This includes lakes and ponds less
than 20 acres in surface area and their submerged aquatic beds, and lakes and ponds planted with game
fish by a governmental or tribal authority.

{ 3) Habitats recognized by federal or state agencies for federal and/or state listed endangered,
threatened and sensitive species documented in maps or databases available to Kitsap County and
which, if altered, may reduce the likelihood that the species will maintain and reproduce over the long
term.
(++4) Areas targeted for preservation by the federal, state and/or local government which provide fish
and wildlife habitat benefits, such as important waterfowl areas identified by the U.S. Fish and Wildlife
Service.
(+145) Areas that contain priority habitats or priority species.
j) Areas that contain habitats and species of local importance.
{+r7) Habitats for state listed candidate and monitored species documented in maps or databases
available to Kitsap County and its citizens, and which, if altered, may reduce the likelihood that the
species will maintain and reproduce over the long term.
(48) Habitats which include attributes such as comparatively high wildlife density; high wildlife species
richness; significant wildlife breeding habitat, seasonal ranges, wildlife corridors, or movement corridors
of limited availability and/or high vulnerability. These habitats may include caves, cliffs, islands,
meadows, old-growth/mature forest, snag -rich areas, talus slopes, and urban natural open space.
20.162.0 07068 Development standards.
Those regulated uses identified below within designated fish and wildlife habitat conservation areas
shall comply with the performance standards outlined in this section. Potential impacts to fish and
wildlife habitat conservation areas or their buffers shall be appropriately identified and mitigated
consistent with Article XII of this chapter. For all regulated activities proposed on a site which contains
or is within 300 feet of a fish and wildlife habitat conservation area, a habitat management plan
consistent with /article IX of this chapter shall ben red
(1) Buffer and Building Setback Requirements. Buffers „r(1) Habitat Assessment Report and
Management Plan. For all regulated uses and activity proposed on a site which contains or is within 300
feet of fish and wildlife habitat conservation area. a habitat assessment shall be prepared by a qualified
wildlife biologist. The habitat assessment shall identify of all fish and wildlife habitat conservation areas
and its buffer. an analysis of species or habitats known or suspected. and assessment of project impact
or effect on the fish and wildlife habitat conservation area or its riparian management zone. If it is
determined that a fish and wildlife habitat conservation area or its riparian management zone does not
occur on or within 300 feet of the site. or if it is demonstrated that the project will comply with the
standard riparian management zone width and building setback requirements. the project may proceed
without any additional requirements under this section. If it is determined that a fish and wildlife habitat

11108823.1 - 366922 - 0001
conservation area does occur on or within 300 feet of the site. and there will be potential temporary or
permanent impacts to a fish and wildlife habitat conservation area or a modification to the riparian
management zone width and/or building setback is proposed. a habitat management plan according to
Article VIII of this chapter shall be prepared.
21 Riparian Management Zones and Building Setback Reauirements. Riparian management zones (RMZ
and setbacks shall be maintained along the perimeter of fish and wildlife habitat conservation areas, as
listed in Table 5. Distances shall be measured from the edge of the channel migration zone (CMZ). where
identified, or the ordinary high water mark (OHM) r from the top of the bank where the OHM cannot
be identified. Buff^rsOHWM), whichever is greater. Riparian management zones shall be retained in
their natural condition.it is acceptable, however, enhanee t,",c except where the buffer by planting
indigenous vegetation, as approved by the d p rtmentcan be enhanced to improve its functional
attributes. Riparian management zones do not apply to those segments of stream that are piped.
a. Alteration of buffer areas may be allowed for water dependent and water related activities subject
to the city's shoreline master program (Chapter 20.164 POMC), and for development authorized by
POMC 20.162.032, Exemptions POMC 20.162.034, Exceptions, POMC 20.162.036, Variances, or
POMC 20.162.038, Nonconforming— Existing structures.
The buffe-rri arian management zone width shall be increased to include streamside wetlands which
provide overflow storage for stormwaters, feed water back to the stream during low flows or
provide shelter and food for fish. In braided channels, the ordinary high water markOHWM or top of
bank shall be defined so as to include the entire stream feature. Refuse shall not be placed in
buffersa riparian management zone.
b. Where a legally established substantial improvement or development transects a riparian
management zone, the director may approve a modification of the minimum required RMZ to the
edge of the substantial improvement or development if the part of the riparian management zone
on the other side of said feature does not provide any buffer functions to protect the fish and
wildlife habitat conservation area in question.
c. An additional building setback of 15 feet is required from the edge of all fish and wildlife habitat
conservation areas.
i. Minor structural impervious surface intrusions into the building setback may be permitted
on a case -by -case basis when an applicant demonstrates to the department that the
proposed intrusion would not adversely affect buffer function.
d. Standard buffers and building setbacks for fish and wildlife habitat conservation areas shall be
required for all regulated uses and activities as per Table 5 of this Article.
e. If the riparian management zone includes a geologically hazardous area(s). the standard riparian
management zone width is greater than the extent of the geologically hazardous area or the riparian
management zone extends to the top of slope of the geologically hazardous areas, the applicable
riparian management zone will be whichever width is greater.
3) Riparian Management Zone Interruptions. Where a legally established developed roadway or

Article V. Geologically Hazardous Areas
20.162.0740742 Purpose.
This chapter applies to all regulated uses included in the critical areas ordinance within 300 feet of areas
designated as geologically hazardous areas, as categorized in POMC 20.'20.162.076. The intent
of this chapter is to:
(1) Provide standards to protect human life and property from potential risks;
(2) Control erosion, siltation, and water quality to protect fish and marine shellfish;
(3) Provide controls to minimize erosion caused by human activity;
(4) Use innovative site planning by placing geologically hazardous areas and buffers in open space. a�4
tronsfcrring density to morc citable 3rc3s on +h., . itc.
20.162.0740764 Geologically hazardous area categories.
The following categories shall be used in classifying geologically hazardous areas:
(1) Geologically Hazardous Areas.
(a) Areas with slopes greater than 30 percent and mapped by the Coastal Zone Atlas or spatial
GIS data provided by the Washington Geologic Information Portal! as unstable (U), unstable old land
slides (UOS) or unstable recent slides (URS).
(b) Areas with slopes greater than 30 percent in grade and deemed by a qualified geologist or
geotechnical engineer to meet the criteria of U, UOS, or URS.
(2) Areas of Geologic Concern.
(a) Areas designated U, UOS, or URS in the Coastal Zone Atlas or spatial GIS data provided by the
Washington Geologic Information, with slopes less than 30 percent; or areas found by a qualified
geologist to meet the criteria for U, URS, and UOS with slopes less than 30 percent; or
(b) Slopes identified as intermediate (I) in the Coastal Zone Atlas or spatial GIS data provided by
the Washington Geologic Information, or areas found by a qualified geologist to meet the criteria of I; or
62
11108823.1- 366922 - 0001
(c) Slopes 15 percent or greater, not classified as I, U, UOS, or URS, with soils classified by the
Natural Resources Conservation Service as "highly erodible" or "potentially highly erodible"; or
(d) Slopes of 15 percent or greater with springs or groundwater seepage not identified in
subsection (2)(a), (b), or (c) of this section; or
(e) Seismic areas subject to liquefaction from earthquakes (seismic hazard areas) such as hydric
soils as identified by the Natural Resources Conservation Service, and areas that have been filled to
make a site more suitable. Seismic areas may include former wetlands, which have been covered with
fill; or
(f) Areas with any indications of earth movement such as debris slides, earthflows, slumps and
rock falls; or
(g) Areas with artificial oversteepened or unengineered slopes, i.e., cuts or fills; or
(h) Areas oversteepened or otherwise unstable as a result of stream incision, stream bank
erosion, and undercutting by wave action.
(3) Site -Specific Determination — Geological and Geotechnical Report Provisions. Should the applicant
question the information the city must rely on to determine whether a location contains a geologically
hazardous area or area of geologic concern, the city may ask the applicant to submit the appropriate
geotechnical or geologic report to confirm or modify the existing information known about the area. The
requirements for these reports are contained in Articles VIII and X of this chapter.
The intent of this provision is to allow obviously nongeologically hazardous sites to be determined as
such. Where there is any ambiguity about the potential for geologic hazards whatsoever, the
department will require a geotechnical or geological report, rather than make a nongeologically
hazardous determination.
20.162.0 80786 Development standards.
This chapter applies to all regulated uses in this chapter or within 300 feet of areas designated as
geologically hazardous or areas of concern. Permit applications include submittals for clearing, grading
and building on property containing geologically hazardous areas. Submittal documents prepared by a
licensed engineer may also be required by the department, pursuant to the city's stormwater
regulations and building codes.
(1) Geologically Hazardous Areas and Areas of Geologic Concern.
(a) Approval. Where applicable the department will approve, approve with conditions or deny
the development proposal based on the department's evaluation of specific site conditions. The
department will also consider any proposed mitigation measures included in a geotechnical report, if
one is submitted.
63
11108823.1- 366922 - 0001
(b) Public Works Requirements. The applicant shall submit a land disturbing activity permit
application to the department. The application and supporting documents shall be completed by a
professional engineer licensed in the state of Washington. The submittal documents shall be determined
on a site -specific basis and may be waived by the City Engineer. The documents may include any
combination of, but not be limited to, construction plans, details and specifications for clearing, grading,
erosion and sedimentation control, and stormwater drainage and detailed hydrological, geotechnical,
soils, and drainage reports and analyses.
(c) Minimum Buffer Requirement. The buffer for all geologically hazardous areas and areas of
geologic concern shall include native vegetation from the toe of the slope to 25 feet beyond the top of
the slope unless otherwise allowed supported through a geological report or a site -specific
determination and designed accordingly.
(d) Building/Impervious Surface Setback Requirements.
(i) Geologically Hazardous Areas. The minimum building and impervious surface setback from
the top of slope 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 25 feet.
(ii) Areas of Geologic Concern. A minimum 40 -foot building and impervious surface setback shall
be maintained from the top of slope. As required in subsection (1)(c) of this section, the 25 feet adjacent
to the top of the slope shall be retained as a native vegetation buffer, with an additional minimum 15 -
foot building and impervious surface setback. The department may decrease the setback when such a
setback would result in a greater than 1:1 slope setback or as may be allowed supported through a
geological report or a site -specific determination.
(iii) Toe of Slope Building Setback. A geotechnical report may be required for any new
construction within 2-90300 feet of a geologically hazardous area. The department will make a
determination based on slope height and stability indicators. Where slope hazard indicators are not
identified, the requirements of the International Building Code Section 1 405 r Section 8403 will apply.
(e) Buffer and Building Setback Modifications — Report Recommendations. The minimum native
vegetation buffer 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 hazard and/or landslide hazard area (see Articles VIII
and X of this chapter for geological and geotechnical report requirements). Should the geotechnical
report indicate that a greater buffer and/or building setback is required than specified in this section,
the greater buffer and/or building setback shall be required. The department may determine through a
site visit, a special report or mapping, that an increased buffer and/or building setback is required from
the critical area.
(f) Time Limitations. For major new development, and where required for minor new development,
clearing, and grading, shall be limited to the period between May 1st to October 1st, unless the
applicant provides an erosion and sedimentation control plan prepared by a professional engineer
licensed in the state of Washington that specifically and realistically identifies methods of erosion
control for wet weather conditions.
64
11108823.1- 366922 - 0001
(g) Field Marking Requirements. For major new development, the proposed clearing for the project and
all critical area buffers shall be marked in the field for inspection and approval by the department prior
to beginning work. Field marking requirements for minor new development will be determined on a
case -by -case basis by the department. The field marking of all buffers shall remain in place until
construction is completed and final approval is granted by the department. Permanent marking may be
required as determined necessary to protect critical areas or their buffers.
(h) Cut and Fill Slopes. The faces of all cut and fill slopes shall be protected to prevent erosion as
required by the engineered erosion and sedimentation control plan.
(i) Development Impact Standards. All discharge of runoff from the development site shall be of like
quality, flow rate, and velocity as that which flowed from the site prior to development. In addition, all
stormwater flows shall be accepted onto, and shall be discharged from, the development site at the
natural or otherwise legally existing locations. The proposed development shall not decrease the slope
stability of any area within 200 feet300 feet of the property boundary.
(j) Development Risk Standard. In cases where a special report indicates a significant risk to public
health, safety and welfare, the department shall deny or require revision of the site development
proposal.
(k) Additional Clearing Standards.
(i) Only the clearing necessary to install temporary erosion control measures will be allowed prior to the
clearing for roads and utilities construction.
(ii) Clearing for roads and utilities shall be the minimum necessary and shall remain within marked
construction limits.
(iii) Clearing for overhead power lines shall be the minimum necessary for construction and will provide
the required minimum clearances of the serving utility.
(I) Existing Logging Roads. Where existing logging roads occur in geologically hazardous areas or areas of
geologic concern, a geological or geotechnical report may be required prior to use as a temporary haul
road or permanent access road under a conversion or COHP forest practices application.
(n) Vegetation Enhancement. The department may require enhancement of buffer vegetation to
increase protection to geologically hazardous areas or areas of geologic concern.
(o) Seismic Hazard Area Development Standards.
(i) Proposed new development within a seismic hazard area shall be in accordance with the Uniform
Building Codc (UBC) Earthquake Dcign Standards for Scimic Risk Zone 3 of Washington State. Building
Code as adopted in POMC 20.200.
65
11108823.1- 366922 - 0001
(ii) Applicants for public and commercial building proposals within seismic hazard areas shall submit a
geotechnical report addressing any fill or grading that has occurred on the subject parcel. Any fill placed
for such development shall have documented construction monitoring as required by the lntcrnational
Building Code.
(iii) All major new development in seismic hazard areas shall require a geotechnical report. Minor new
development may also require a geotechnical report, as determined by the department.
(iv) The development proposal may be approved, approved with conditions or denied based on the
department's evaluation of the proposed mitigation measures to reduce seismic risk.
(2) Prohibitions.
(a) Critical facilities, as defined in Article II of this chapter, are prohibited in geologically hazardous areas.
(b) In geologically hazardous areas with slopes greater than 80 percent, no development will be allowed
either on or within the defined buffer area, unless approved by the department after review of a
geotechnical report. The defined buffer zone for geologically hazardous areas is defined in subsection
(1)(d) of this section.
(c) On -site sewage disposal should be avoided in geologically hazardous areas and their buffers. In cases
where such areas cannot be avoided, review by a geologist or a geotechnical engineer licensed in the
state of Washington will be required in coordination with the Bremerton-Kitsap County health district.
(Ord. 010-18 § 31; Ord. 019-17 § 18 (Exh. 1)).
Article VI. Frequently Flooded Areas
20.162.0800808 Purpose and requirements.
The purpose of this article is to protect the public health, safety and welfare from harm caused by
flooding. It is also the intent to prevent damage and/or loss to both public and private property.
Pursuant to this purpose, the city uses Chapter 20.170 POMC, Flood Damage Prevention, adopted by
reference, which designates special flood hazard areas and establishes permit requirements for these
areas.
In addition, the Kitsap County GIS database for critical drainage areas of the stormwater management
regulations will be included for areas of review under frequently flooded areas
Article VII. Critical Aquifer Recharge Areas
20.162.08208280 Purpose.
The intent of this article is to provide water quality protection associated with aquifer recharge areas
through the regulation of land use activities that pose a potential contaminant threat or could increase
the vulnerability of the aquifer. It is the policy of the city to accomplish the following:
11108823.1- 366922 - 0001
(1) Identify, preserve and protect aquifer recharge areas and prevent degradation of the quality of
potable groundwater;
(2) Recognize the relationship between surface and groundwater resources; and
(3) Balance competing needs for water while preserving essential natural functions/processes.
20.162.684084-2 Critical aquifer recharge area categories.
A critical aquifer recharge area is a geographical area which provides the recharge to an aquifer(s) which
is a current or potential potable water source and, due to its geological properties, is highly susceptible
to the introduction of pollutants, or because of special circumstances, has been designated as a critical
aquifer recharge area in accordance with WAC 365-190-080 by the city. Critical aquifer recharge areas
under this chapter may be established based on general criteria or specifically designated due to special
circumstances.
(1) Category I — Critical Aquifer Recharge Areas. The following general criterion is established to
designate critical aquifer recharge areas: wellhead protection zones around Group A water system
supply wells:
(a) Areas inside the one-year time of travel zone for Group A water system wells, calculated in
accordance with the Washington State Well Head Protection Program.
(b) Five-year time of travel zones in wellhead protection areas are included as critical aquifer
recharge areas under the following condition: The five-year time of travel zone is included when the well
draws its water from an aquifer that is at or above sea level and is overlain by permeable soils listed in
subsection (2)(a) of this section without an underlying protective impermeable layer (see below).
(2) Category II — Aquifer Recharge Areas of Concern. Areas which provide recharge to aquifers that
provide current or potential potable water supplies and are vulnerable to contamination, and meet any
one of the following general criteria:
(a) Highly Permeable Soils — Locations Where Surface Soil Layers Are Highly Permeable. Soils
that have relatively high permeability and high infiltration potential may provide for groundwater
recharge, but also may enhance transfer of contaminants from the surface to groundwater. For these
reasons the locations where surface soils are highly permeable are considered aquifer recharge areas of
concern.
The general location and characteristics of soils in Kitsap County and the city is given in the Soil Survey of
Kitsap County by the U.S. Department of Agriculture, Natural Resources Conservation Service (SCS). The
soil survey information is available on the Kitsap County geographic information system (GIS). The
following soil types are considered to have relatively high permeability and are aquifer recharge areas of
concern.
The following soils have relatively high infiltration:

Poulsbo/Ragnar
41, 42, 43, 44, 45, 46, 47
(b) Areas Above Shallow Principal Aquifers. Surface areas above shallow principal aquifer(s) which are
not separated from the underlying aquifers by an impermeable layer that provides adequate protections
to preclude the proposed land use from contaminating the shallow aquifer(s) below are considered
aquifer recharge areas of concern. This generally includes principal aquifers in subsurface hydrogeologic
units Ogl, Ogla, Ogg and portions of Og3 that are within 300 feet of the ground surface
20.162.0860864 Development standards.
Standards for development shall be in accordance with the provisions below and the requirements of
the underlying zoning:
(1) A hydrogeological report will be required on sites that have been identified as having characteristics
with high infiltration rates, or having a high aquifer recharge or infiltration potential for land uses
identified in Table 20.162.086, unless determined unnecessary upon coordination with agencies with
jurisdiction (Bremerton-Kitsap County health district and/or affected water purveyors). This evaluation
shall apply to impacts on both groundwater and surface water, as it relates to recharge areas (see
requirements in Article VIII of this chapter, Special Reports).
(2) Affected water purveyors will be notified and requested to comment during the preliminary phases
of the city's review process on the proposed land use and potential impacts. The purveyor may
recommend appropriate mitigation to reduce potential impacts. The department will consider these
recommendations to develop appropriate permit conditions.
(3) This section shall not affect any right to use or appropriate water as allowed under state or federal
law. In addition, these requirements do not apply to those activities which have potential contaminant
sources below threshold amounts as set forth in applicable state RCWs or local regulations.
In addition to the general standards above, the following will apply:
(a) Category I — Critical Aquifer Recharge Areas. Land uses identified in Table 20.162.086 are
prohibited in critical aquifer recharge areas. Requests for waivers shall include a hydrogeological report,
which includes a detailed risk -benefit analysis that considers credible, worst -case scenarios. The waiver
will be evaluated and treated as a special use review, similar to the review process in Article VIII of this
chapter, Special Reports, by the review department, the health district, and the affected water
purveyors.
(b) Category II — Aquifer Recharge Areas of Concern. Applicants proposing operations that pose
a potential threat to groundwater as defined in Table 20.162.086 in aquifer recharge areas of concern
11108823.1- 366922 - 0001
may be required to submit a hydrogeological report. The scope of the report shall be based on site -
specific conditions. The need for additional information will be determined by the department, the
health district and the affected water purveyor. Based on the results of the report, controls, mitigation,
and/or other requirements will be established as a prerequisite for the development proposal being
approved.
(c) The department will also notify the health district and affected water purveyors through the
environmental review process when those development activities listed in Table 20.162.086 are
proposed outside the areas designated critical aquifer recharge areas and aquifer recharge areas of
concern.

(3) WetIand20.162.0986 Mitigation Report Ilan.
(1) Whenever the department has determined that losses of regulated wetlandscritical areas are
necessary and unavoidable, or a review of a regulated wetlandcritical area or its buffer is proposed, or
an exception to uses is allowed or a variance to standards is granted, a mitigation plan shall be prepared
which is considered in the following order of preference and for consistency with POMC 20.162.026:
(+a) Avoiding the impact altogether by not taking a certain action or parts of actions. This may be
accomplished by selecting a reasonable alternative that does not involve we critical area or
wetianndcritical area impacts, applying reasonable mitigation measures, such as drainage and erosion
control, alternative site planning, and/or using best available technology. In reviewing development
73
11108823.1- 366922 - 0001
proposals required to submit a wetlands mitigation plan, the department shall first determine if the
impact can be avoided (e.g., impacts cannot be avoided if denial of the development proposal or parts
thereof or mitigation measures would result in an extraordinary hardship and denial of reasonable use
of property).
(++b) Minimizing impacts by limiting the degree or magnitude of the action and its
implementation, by using appropriate technology, or by taking affirmative steps to avoid or reduce
impacts. This may be accomplished by selecting a reasonable alternative that avoids most
,.,critical area impacts, applying reasonable mitigation measures, such as drainage and erosion
control, alternative site planning, and/or using best available technology. In reviewing development
proposals required to submit a wed mitigation plan, the department shall determine if the impact
can be first avoided and secondly minimized. Impacts cannot be avoided or minimized if denial of the
development proposal or parts thereof or mitigation measures would result in an extraordinary
hardship and denial of reasonable use of property.
(+++c) Rectifying the impact by repairing, rehabilitating, or restoring the affected environment.
This may be done by reestablishing ,.,critical area and wdcritical area buffer characteristics
on a site which have been lost by alterations or activities. Rectifying shall be accomplished in accordance
with a mitigation plan, which has been prepared in accordance with the requirements in subsection
(3)(d) of this section and has been approved by the department. In reviewing development proposals
required to submit a wetland mitigation plan, the department shall determine if the impact should be
rectified. Impacts can be rectified if mitigation measures would not result in an extraordinary hardship
and denial of reasonable use of the property.
(+vd) Compensating for the impact by replacing, enhancing, or providing substitute resources or
environments. Unless required elsewhere by this chapter. compensation shall occur on -site and be in -
kind. When it is adequately demonstrated that there is no feasible opportunity for on -site
compensation the director may approve an offsite compensatory approach. This may be done by
intentionally creating wetlands and wetland buffers at another location where none currently exist,
improving existing wetlandscritical areas and _wetland buffers at another location, or otherwise
providing a substitute wetlandcritical area resource at another location as compensation for any
unavoidable adverse wetland impacts. Compensating shall be accomplished in accordance with a
mitigation plan, which has been prepared in accordance with the requirements in subsection (3)(d) 4jof
this section and has been approved by the department. In reviewing development proposals required to
submit a wetland mitigation plan, the department shall determine if the impact should be compensated.
Impacts can be compensated if compensation and mitigation measures would not result in an
extraordinary hardship and denial of reasonable use of property. Compensation of wetlanndcritical area
impacts may be waived by the department for development authorized by POMC
20.162.03403620.162.038, Exceptions.
(2) The overall goal of any mitigation plan shall be no net loss of regulated wetlandcritical area
functions and acreage.
(e3) Those persons proposing weld -compensatory mitigation projects shall show that the
compensation project is associated with an activity or development otherwise permitted and that the
74
11108823.1- 366922 - 0001
restored, created, or enhanced wetdcritical area will be as persistent as the wctlandfeature it
replaces by accomplishing the following:
(+a) Demonstrate sufficient scientific expertise, supervisory capability, and financial resources to
carry out the project; and
(4b) Demonstrate the capability for monitoring the site and for making corrections during this
period, if the project fails to meet projected goals; and
(4c) Protect and manage or provide for the protection and management of the compensation
area to avoid further development or degradation.
(d) Wetland mitigation(4) Mitigation plans shall be implemented by the project applicant, and include
the following components:

design recommendations; i.e., recommendations for foundations (loading, sizing, depth, or settlement
estimates), pile or pier design, retaining structures, or recommendations for construction on slopes
steeper than 30 percent, must be prepared by or in conjunction with a licensed geotechnical engineer as
defined in subsection (2) of this section.
A geological report shall include the above, with the exception of engineering design recommendations,
and need not make use of subsurface investigative measures. As the report will not include engineering
recommendations, a geological report may be prepared by a geologist or engineering geologist as
defined in subsection (2) of this section.
(2) Geotechnical reports shall be prepared by a geotechnical engineer (a civil engineer licensed by the
state of Washington who is knowledgeable of regional geologic conditions and who has at least four
years' professional experience in landslide and/or seismic hazard evaluation). Geological reports may be
prepared by a geologist, engineering geologist or geotechnical engineer knowledgeable in regional
geologic conditions and having at least four years' professional experience in site evaluation and

conditions rather than measures that have not yet been successfully approved, designed or constructed
(e.g., slope recontouring, slope retaining walls, vegetation improvements, bulkheads, etc.). Shoreline
bulkheads and retaining walls may only be utilized as an engineering solution where it can be
demonstrated that an existing residential structure cannot be safely maintained without such measures,
and that the resulting retaining wall is the minimum necessary to provide a stable building area for the
structure.
20.162.O1066 Hydrogeological report R.
A hydrogeological report shall be required for certain proposed operations based on a consultation with

no significant degradation of groundwater quality; and
(j) Other information as required by the Bremerton-Kitsap County health district.
(2) The hydrogeologic report shall be prepared by a professional geologist/hydrologist or by a soil
scientist with a strong background in geology as demonstrated by course work from an accredited
college or university and/or has a minimum of five years' experience.
(3) Applications for development or operations with underground storage of petroleum products will be
processed using the appropriate procedure as specified in existing state regulations and city ordinances.
(4) Analysis for a specific parcel(s), using the criteria outlined below, will be employed to determine if
the soils present require a recharge area designation. Data collection will include, at a minimum: six soil
logs to a depth of 10 feet (or to a depth four feet below the lowest proposed excavation point
whichever is greater) for each acre in the parcel(s) being evaluated. At least one well which is 300 feet or
greater in depth with an adequate drilling report must be available within one mile. The associated data
shall be analyzed and included in the hydrogeologic report to determine the presence of highly
permeable soils with the recharge area designation.
For development proposals within aquifer recharge areas of concern, the hydrogeological report may be
based on quarter -quarter section basis locations where the number of wells within a half -mile radius is
36 or more, and are designated aquifer recharge areas. To facilitate computer analysis, the evaluation
may be done on a quarter -quarter section basis using the quarter -quarter section in which a parcel of
interest is located and all the surrounding quarter -quarter sections, in place of the half -mile circle.
