Section 100. General Provisions and Administration

16.20.105 Purpose.

It is the intent of the city of Poulsbo that the beneficial structure, value and functions (RCW 36.70A.172(1) and WAC 365-195-825(2)(b)) of critical areas be preserved, and potential damage or public costs associated with the inappropriate use of such areas be minimized by reasonable regulation of uses within, adjacent to or directly affecting such areas. Further, the purpose of this chapter is to identify and protect critical areas as required by the Growth Management Act of 1990 (Title 36, Laws of 1990, as amended), which are wetlands, fish and wildlife habitat conservation areas, areas subject to frequent flooding, geologically hazardous areas, and critical aquifer recharge areas. (Ord. 2017-10 § 2 (Exh. A (part)), 2017: Ord. 2007-24 § 2 (part), 2007)

16.20.110 Identification of critical areas.

The critical areas in the city of Poulsbo are hereby further divided into the following types:

A.    Wetland critical areas;

B.    Fish and wildlife habitat conservation critical areas;

C.    Geologically hazardous areas;

D.    Critical aquifer recharge areas;

E.    Frequently flooded areas. (Ord. 2017-10 § 2 (Exh. A (part)), 2017: Ord. 2007-24 § 2 (part), 2007)

16.20.115 Applicability.

A.    The city of Poulsbo shall not grant any permit, license or other development approval to alter the condition of any land, water or vegetation, or to construct or alter any structure or improvement, nor shall any person alter the condition of any land, water or vegetation, or construct or alter any structure or improvement, for any development proposal regulated by this chapter, except in compliance with the provisions of this chapter. Failure to comply with the provisions of this chapter shall be considered a violation and subject to enforcement procedures as provided for in this chapter.

B.    This title applies to all uses and activities within areas or adjacent to areas designated as regulated critical areas and/or their buffers unless identified as exempt in Section 16.20.120. Such activities include, but are not limited to:

1.    Removing, excavating, disturbing, or dredging soil, sand, gravel, minerals, organic matter, or materials of any kind;

2.    Dumping, discharging, or filling with any material;

3.    Draining, flooding, or disturbing the water level or water table;

4.    Driving pilings or placing obstructions;

5.    Constructing, demolishing, or altering the size of any structure or infrastructure that results in disturbance of a critical area or the addition of any impervious surface coverage to a site that results in disturbance of a critical area;

6.    Destroying or altering vegetation through clearing, grading, harvesting, shading, or planting vegetation that would alter the character of a critical area;

7.    Activities that result in significant changes in water temperature and physical or chemical characteristics of water sources, including quantity and pollutants; and

8.    Any other activity that has a potential to significantly adversely impact or alter a critical area or established buffer not otherwise exempt from the provisions of this chapter.

C.    Requirements for critical areas are in addition to, or to be combined with, requirements of other development regulations, including, but not limited to, the Poulsbo zoning ordinance, clearing and grading ordinance, subdivision ordinance and the shoreline master program. In case of conflict with other development regulations or other critical area requirements, the more restrictive provision or combinations of provisions shall apply. Further, any parts of wetland or nonwetland fish and wildlife critical areas also included in the one-hundred-year floodplain by Chapter 15.24, Floodplain Management, shall also be subject to the provisions of that chapter.

D.    Uses and activities in critical areas or their buffers and building setbacks from the critical area buffer, for which no other land use or development permit or approval is required by other city ordinance, remain subject to the development standards and other requirements of this section, and a critical area permit shall be required unless specifically identified as exempt.

E.    Any development proposal that includes a critical area or its buffer, or is within three hundred feet of a critical area, is subject to review under the provisions of this chapter.

F.    The location and extent of all mapped critical areas shown on the city of Poulsbo critical area maps1 are approximate and shall be used as a general guide only for the assistance of property owners and city administrators. The type, extent and boundaries shall be determined in the field by a qualified specialist or specialists according to the requirements of this chapter. The critical area maps1 are adopted as part of this chapter and are incorporated herein by this reference.

3.    In the event of a conflict between the mapped areas and the criteria or standards of this chapter, this chapter shall apply. In the event that a boundary determination made by a qualified specialist finds that a critical area is not present on the property, the critical area designation shall be considered for removal from the map. In the event that a critical area which meets the criteria or standards for a critical area is found on a property not mapped as a critical area, the property shall be deemed to contain a critical area and shall be treated as if it had been included on the appropriate critical area map.

4.    The planning director shall have the authority to issue revised critical area maps when new or revised information becomes available regarding the presence or absence of critical areas within the city or urban growth boundary. (Ord. 2017-10 § 2 (Exh. A (part)), 2017: Ord. 2012-10 § 5 (Exh. D) (part), 2012; Ord. 2007-24 § 2 (part), 2007)

16.20.120 General exemptions.

The following activities are exempt from the requirements of this chapter. All exempted activities shall use reasonable methods to avoid potential impacts to critical areas. To be exempt from this chapter does not give permission to degrade a critical area or ignore risk from natural hazards. Any incidental damage to, or alteration of, a critical area that is not a necessary outcome of the exempted activity may be considered a violation of this chapter and subject to enforcement and restoration under Section 16.20.150.

The following developments, activities, and associated uses shall be exempt from the provisions of this chapter; provided, that they are otherwise consistent with the provisions of other local, state, and federal laws and requirements:

A.    Emergency activities necessary to prevent an immediate threat to public health, safety, or welfare, or that pose an immediate risk of damage to private property and that require remedial or preventative action in a time frame too short to allow for compliance with the requirements of this chapter.

Emergency actions that create an impact to a critical area or its buffer shall use reasonable methods to address the emergency; in addition, they must have the least possible impact to the critical area or its buffer. The person or agency undertaking such action shall notify the city of Poulsbo within one working day following commencement of the emergency activity. Within thirty days, the director shall determine if the action taken was within the scope of the emergency actions allowed in this subsection. If the director determines that the action taken, or any part of the action taken, was beyond the scope of an allowed emergency action, then the enforcement provisions of Section 16.20.150 shall apply. Upon cessation of the emergency, restoration of the critical areas and buffers impacted by the emergency action shall be required in a timely manner. Upon abatement of the emergency situation, any permit that would have been required to be obtained under the Poulsbo Municipal Code shall be required.

B.    Existing and ongoing agricultural activities on lands containing critical areas. For the purpose of this chapter, “existing and ongoing” means that the activity has been conducted within the past five years. Any expansion of agricultural activities shall conform to the provisions of this chapter.

C.    Normal and routine maintenance and operation of existing retention/detention facilities, biofilters and other stormwater management facilities, irrigation and drainage ditches, farm ponds, manure lagoons and livestock water ponds; provided, that such activities shall not involve expansions or alterations that would increase the impact on or expand such uses further into critical areas not currently being used for such activity.

D.    Structural alterations to buildings, permitted under the underlying zoning district, that do not alter the structural footprint or introduce new adverse impacts to a critical area.

E.    Normal and routine maintenance or repair of existing utility structures within a right-of-way or existing utility corridor or easements, including cutting, removal and/or mowing of vegetation above the ground that utilizes best management practices and does not expand the use or activity further into the critical area.

F.    Installation, construction, replacement, operation or alteration in improved public road right-of-way of all electric facilities, lines, equipment or appurtenances; this does not include substations, water and sewer lines, all natural gas, cable communications and telephone facilities, lines, pipes, mains, equipment or appurtenances.

G.    Forest practices conducted pursuant to Chapter 76.09 RCW, except Class IV (general conversions) and conversion option harvest plans (COHP).

H.    Where a threat to human life or property is demonstrated, the director may allow removal of danger or hazard trees within a critical area or its buffer, subject to the following criteria:

1.    Tree removal is the minimum necessary to balance protection of the critical area and its buffer with the protection of life and property;

2.    The critical area or its buffer shall be replanted as determined by the director. The director shall coordinate review with the Washington State Department of Fish and Wildlife as determined necessary to assure habitat protection. The director may require the applicant to consult with a professional forester or a certified arborist prior to tree removal. Danger tree abatement may be achieved by felling or topping the tree. Habitat needs may require leaving the fallen tree in the riparian corridor or maintaining a high stump.

I.    To qualify for exemption under this section, the construction of pedestrian trails shall be unpaved and established as a nature path when located in the buffer or critical area; should be generally parallel to the perimeter of the critical area or provided at specific points; located only in the outer twenty-five percent of the buffer area as feasible; are not intended for motorized use; and are no wider than five feet, unless additional width is necessary for safety along a precipice, steep hillside, or other hazardous area. All trail construction shall avoid damaging significant trees and other habitat elements to the greatest degree possible, and does not cross or alter any regulated streams or drainages. Trails proposed to be located in a landslide hazard area or its setback shall be constructed in a manner that does not increase the risk of landslide or erosion.

Trails that do not meet the parameters of this exemption may be permitted through the underlying land use permit or critical areas permit, subject to the standards of Section 16.20.235(G) for wetlands, and Section 16.20.320(F) for trails proposed to be located in a fish and wildlife habitat conservation area buffer.

J.    Normal and routine maintenance of existing structures, landscaping and gardens, provided they comply with all other regulations in this chapter. Expansions, alterations, or repair in excess of fifty percent of the market value of the improvement shall be reviewed under the provisions of Section 16.20.125, Standards for existing development.

K.    Interrupted Wetland and Fish and Wildlife Habitat Conservation Area Buffers.

1.    Where a legally established, preexisting use of the buffer exists (such as a road or structure that extends into the current regulated buffer), those proposed activities that are within the wetland or stream buffer, but are separated from the critical area by an existing permanent substantial improvement, which serves to eliminate or greatly reduce the impact of the proposed activity upon the critical area, are exempt from establishing full width of the buffer; provided, that impacts to the critical area do not increase.

If a development or improvement is proposed that may result in increased impacts to the existing critical area buffer, even if separated by an existing permanent improvement (such as a road or structure), it shall be evaluated and additional buffer may be required along the impact area of the interruption. To determine if additional buffer is required, a functional analysis may be required. In determining whether a functional analysis is necessary, the planning director shall consider the hydrologic and habitat connection potential and the extent and permanence of the interruption.

2.    Where a legally established, preexisting structure or use is located within a regulated buffer area and where the regulated buffer is fully paved and does not conform to the interrupted buffer provision above, the buffer will end at the edge of pavement, adjacent to the critical area.

L.    The following can be removed by hand or hand-held light equipment; provided, that appropriate methods are used to protect native vegetation and water quality:

1.    English ivy may be removed from plants on which it is adhered or rolled up off the ground provided ground disturbance is minimal and does not cause erosion.

2.    Regulated noxious weeds as listed on the Kitsap County noxious weed list that are required to be eradicated (Class A and Class B) as specified by the Kitsap County Noxious Weed Board.

3.    Noxious weeds (Class A and B) removal in a critical area buffer when the total area is one thousand square feet or less and slopes are less than fifteen percent.

4.    Refuse and debris, provided materials are on the soil surface and provided ground and/or vegetation disturbance is minimal and does not cause erosion.

5.    Additional noxious weeds (Class A and B) removal can occur through a critical area permit and buffer enhancement plan.

M.    Watershed restoration projects that conform to the provisions of RCW 89.08.460 shall be reviewed without fee and approved within forty-five days per RCW 89.08.490.

N.    Fish enhancement projects that conform to the provisions of RCW 77.55.181 shall be reviewed without fee and comments provided as specified in RCW 77.55.181.

O.    Site investigative work necessary for land use application submittals such as surveys, soil logs, percolation tests, and other related activities. Critical area impacts shall be minimized and disturbed areas shall be immediately restored. (Ord. 2017-10 § 2 (Exh. A (part)), 2017: Ord. 2007-24 § 2 (part), 2007)

16.20.125 Standards for existing development.

Existing development containing a critical area which was lawfully constructed, approved or established prior to the effective date of the ordinance codified in this chapter, but which does not conform to present regulations or standards, may continue as follows:

A.    A legally established, existing structure that does not meet the dimensional standards of this chapter may not be enlarged or altered in any manner unless such enlargement or alteration is in conformance with the following provisions. A critical area permit, a Type II review, shall be required for any proposal which includes reconstruction or remodeling in excess of fifty percent of the market value.

B.    Routine maintenance and repair of preexisting legally established structures as authorized in Section 16.20.120(J). Repair in excess of fifty percent of the market value of the structure shall be considered reconstruction. Normal repair and maintenance does not require a critical area permit.

C.    A legally established structure that has been made nonconforming due to the adoption of this code may be remodeled up to fifty percent of the market value so long as all of the following provisions are met:

1.    The remodel shall not introduce any new, or expand existing, impacts to a critical area unless such impacts are fully mitigated as required for reconstruction in subsection (E)(1) of this section; and

2.    All other standards and requirements contained in the Poulsbo Municipal Code are met.

D.    Residential structures, including multifamily, in a residential zoning district, destroyed by a catastrophe or fire, may be reconstructed up to the original size, placement and density. Structural repair must be initiated within two years of the catastrophe and all of the following provisions apply:

1.    The structure does not necessarily need to be rebuilt on the original footprint if it is requested by the property/homeowner and it is determined that an alternative location on the lot will provide greater protection to the critical area; and

2.    Best management practices shall be employed to assure reconstruction does not negatively impact the critical area.

E.    Preexisting legally established structures that have been made nonconforming due to the adoption of this code and that are located outside a flood hazard area and active landslide hazard area may be remodeled beyond fifty percent of the market value or reconstructed; provided, that such reconstruction and/or remodeling does not increase the footprint area nor extend beyond the existing ground coverage toward a critical area and:

1.    The reconstruction shall be appropriately mitigated to ensure the existing value and function of the critical area is not degraded; further, historic impacts of the existing site development shall be mitigated as per subsection F of this section; and

2.    The reconstruction and/or enlargement meets all other standards and requirements contained in the Poulsbo Municipal Code.

F.    Where mitigation is required in subsection (E)(1) of this section, the applicant shall provide mitigation measures to reduce historic impacts on the critical area which may include requirements to enhance vegetative areas adjacent to the critical area and retrofit existing impervious areas for minimum stormwater quality treatment. Where mitigation opportunities on-site are limited or improvements off-site can be shown to better enhance the critical area at a watershed scale, off-site mitigation measures may be required.

G.    Additional provisions affecting expansions of existing development along Poulsbo Creek are located in Section 16.20.315(F). (Ord. 2017-10 § 2 (Exh. A (part)), 2017: Ord. 2007-24 § 2 (part), 2007)

16.20.130 Reasonable use exception.

If the application of this chapter would deny all reasonable use of the property, the applicant may apply for a reasonable use exception pursuant to this section.

A.    A request for a critical area reasonable use exception shall be filed with the director and shall be combined with the underlying development permit. The reasonable use exception request shall be considered a Type III application.

B.    The review authority, in granting a reasonable use exception, must determine that all of the following criteria are met:

1.    Application of this chapter would deny all reasonable use of the property;

2.    There is no other reasonable use with less impact on the critical area;

3.    The proposed development does not pose an unreasonable threat to the public health, safety or welfare on or off the development proposal site;

4.    Any alterations permitted to these critical areas shall be the minimum necessary to allow for reasonable use of the property;

5.    The inability to derive reasonable use of the property is not the result of actions by the applicant after the effective date of the ordinance codified in this chapter;

6.    Diminished value shall not be considered denial of all reasonable use; and

7.    The proposal will result in no net loss of critical area functions and values consistent with best available science.

C.    Any authorized alteration of a critical area or buffer under this section shall be subject to conditions established by the city and shall require mitigation under an approved special report pursuant to Section 700 of this chapter. (Ord. 2017-10 § 2 (Exh. A (part)), 2017: Ord. 2007-24 § 2 (part), 2007)

16.20.133 Public agency and utility exception.

A.    A request for a critical area public agency and utility exception may be made if the application of this chapter would prohibit a development proposal by a public agency or public utility. The public agency and utility exception shall be considered a Type III application.

B.    The review authority, in granting a public agency and utility exception, must determine that all of the following criteria are met:

1.    There is no other practical alternative to the proposed development with less impact on the critical areas;

2.    The application of this chapter would unreasonably restrict the ability to provide services to the public;

3.    The proposal does not pose an unreasonable threat to the public health, safety, or welfare on or off the development proposal site;

4.    The proposal will result in no net loss of critical area functions and values consistent with the best available science; and

5.    The proposal is consistent with other applicable regulations and standards.

C.    Any authorized alteration of a critical area under this section may be subject to conditions established by the city and shall require mitigation under an approved special report pursuant to Section 700 of this chapter. (Ord. 2017-10 § 2 (Exh. A (part)), 2017: Ord. 2007-24 § 2 (part), 2007)

16.20.135 Notice to title.

Project proponent(s) may be required to file a notice to title with the Kitsap County auditor on all development proposals subject to this chapter, and containing any critical area or its buffer. After review of the development proposal, the director will establish critical area development conditions in accordance with this chapter. These standards will be identified on the approved notice to title. The proponent shall submit proof that the required notice has been filed before the director will issue the underlying permit’s notice of decision. (Ord. 2017-10 § 2 (Exh. A (part)), 2017: Ord. 2007-24 § 2 (part), 2007)

Category I wetlands include relatively undisturbed estuarine wetlands larger than one acre, wetlands with a high conservation value that are identified by scientists of the Washington Natural Heritage Program/DNR, bogs, mature and old-growth forested wetlands larger than one acre, wetlands in coastal lagoons, interdunal wetlands that score eight or nine habitat points and are larger than one acre, and wetlands that perform many functions very well as demonstrated by a score of twenty-three to twenty-seven total points.

2.    Category II Wetlands. Category II wetlands are difficult, though not impossible, to replace, and provide a moderately high level of functions. Category II wetlands include estuarine wetlands smaller than one acre or disturbed and larger than one acre, interdunal wetlands greater than one acre or are a mosaic of interdunal wetlands that are one acre or larger, and wetlands that perform functions well as demonstrated by a score of twenty to twenty-two.

3.    Category III Wetlands. Category III wetlands are wetlands with a moderate level of function as demonstrated by a score of sixteen to nineteen points, and interdunal wetlands between one-tenth and one acre.

4.    Category IV Wetlands. Category IV wetlands have the lowest levels of functions as demonstrated by a score of nine to fifteen points and are often heavily disturbed.

5.    Wetlands intentionally created from nonwetland areas to mitigate conversion of other wetlands.

B.    Nonregulated Wetlands (RCW 36.70A.030(21)).

1.    Created Wetlands. Wetlands created intentionally from a nonwetland site that were not required to be constructed as mitigation for adverse wetland impacts. These may include, but are not limited to, irrigation and drainage ditches, grass-lined swales, canals, detention facilities, wastewater treatment facilities, farm ponds as defined in this chapter, and landscape amenities.

2.    Road-Construction-Related Wetlands. Wetlands created after July 1, 1990, that were unintentionally created as a result of the construction of a road, street, or highway. The applicant shall bear the burden of proving that the wetland meets these criteria. (Ord. 2017-10 § 2 (Exh. A (part)), 2017: Ord. 2007-24 § 2 (part), 2007)

16.20.220 Application requirements.

A.    Application Procedures for New Development. Any new development on a parcel or parcels containing a regulated wetland or its buffer, or within three hundred feet of a wetland or its buffer, shall provide the special reports listed below, as required by the department, prior to any development authorization by the department:

1.    Wetland assessment report (Section 16.20.725), if wetlands or buffers are within three hundred feet but outside of the parcel or parcels and no buffer impacts, reductions, or setback intrusions are proposed;

2.    Wetland delineation report (Section 16.20.730) if wetland or buffers occur within the parcel or parcels;

3.    Wetland mitigation report (Section 16.20.735), if wetland or buffer impacts are anticipated or if the director requires buffer enhancement; and

4.    Erosion and sedimentation control measures as required by Poulsbo Municipal Code construction and development standards contained in Chapter 12.02.

The director may require additional reports or information to further identify potential impacts to any part of the environment. (Ord. 2017-10 § 2 (Exh. A (part)), 2017: Ord. 2007-24 § 2 (part), 2007)

16.20.225 Determination of wetland boundaries.

A.    Wetland delineation shall be conducted and results reviewed according to the requirements of the U.S. Army Corps of Engineers federal wetland delineation manual and applicable regional supplements. The applicant shall be responsible for hiring a qualified wetlands specialist to determine the wetland boundary through a field survey. This specialist shall stake or flag the wetland boundary. For all new development, and as required by the director, this line shall be surveyed by a professional land surveyor licensed in the state of Washington or recorded using a differential global positioning system. In the event that a global positioning system is used, wetland boundary information, including position accuracies, shall be provided to the city in an electronic data format acceptable to the city. The regulated wetland boundary and regulated buffer shall be identified on all grading, landscaping, site, utility or other development plans submitted in support of the project.

B.    Where the applicant has provided a delineation of a wetland boundary, the director shall require peer-reviewed verification of the wetland boundary by a qualified wetlands specialist at the cost of the applicant, and may require that adjustments to the boundary be made by a wetlands specialist. If a consensus cannot be reached between the applicant and the city of Poulsbo with respect to the location of the wetland boundary, the city may request assistance from the Department of Ecology. (Ord. 2017-10 § 2 (Exh. A (part)), 2017: Ord. 2007-24 § 2 (part), 2007)

16.20.230 Wetland and buffer development standards.

For the purpose of this chapter, a regulated wetland and its buffer is a critical area.

A.    Buffers. Buffers shall be undisturbed native species vegetation areas appropriate to the ecoregion, for the purpose of protecting the integrity, function, and value of wetland resources. If the existing buffer does not consist of vegetation adequate to provide the necessary protection, then either the buffer area should be planted or the buffer width should be increased. Any buffer enhancement proposed shall be through an approved buffer enhancement plan. No uses or activities shall be allowed within the buffer unless as otherwise allowed or permitted by this section. If the buffer has previously been disturbed, the director may require the disturbed buffer area be revegetated pursuant to an approved buffer enhancement plan (see also Section 16.20.740). No refuse, including but not limited to household trash, yard waste and commercial/industrial refuse, shall be placed in the buffer.

B.    Impact of Land Use. Different land use intensities can result in high, moderate, or low levels of impact to adjacent wetlands and buffers. Types of land uses are categorized into impact levels as shown on the following table:

 

Table 16.20.230.A—Types of Land Uses

Level of Impact from Land Use

Types of Land Uses Based on Common Use Categories

High

Residential uses (greater than one unit per acre); schools; churches; public facilities, public/private services and government administrative uses (excluding parks, rights-of-way and utilities); lodging uses; personal, professional, product and automotive services; health care services; commercial and sales uses; animal clinics and kennels; marine-related uses; industrial uses; restaurant uses; museum, club and recreation hall uses; high-intensity parks, outdoor and indoor recreation (golf courses, ballfields, tennis clubs, swimming pools, etc.); conversion to high-intensity agriculture (dairies, nurseries, greenhouses, growing and harvesting crops requiring annual tilling and raising and maintaining animals, etc.); hobby farms.

Moderate

Residential uses (less than one unit per acre); moderate-intensity parks and outdoor recreation (parks with biking, jogging, etc.); conversion to moderate-intensity agriculture (orchards, hay fields, etc.) and paved trails; building of logging roads; utility corridor or right-of-way shared by several utilities and including access/maintenance road.

Low

Forestry (cutting of trees only); low-intensity parks and open space (hiking, bird-watching, preservation of natural resources, etc.) and unpaved trails; utility corridor without a maintenance road and little or no vegetation management.

C.    Buffer Widths. All regulated wetlands shall be surrounded by a buffer as follows, based upon Appendix 8-C, Section 8C.2.3 of Wetlands in Washington State—Volume 2: Guidance for Protecting and Managing Wetlands (Ecology Publication No. 05-06-008):

D.    Buffer Measurement. All buffers shall be measured on a horizontal plane from the regulated wetland edge as marked in the field by the wetlands specialist.

E.    Buffer Width Averaging. The widths of buffers may be averaged if this will improve the protection of wetland functions, or if it is the only way to allow for reasonable use of a parcel. Averaging may not be used in conjunction with any of the other provisions for reductions of buffers in subsection F of this section.

1.    Averaging to improve wetland protection may be permitted when all of the following conditions are met:

a.    The wetland has significant differences in characteristics that affect its habitat functions, such as wetland with a forested component adjacent to a degraded emergent component or a “dual-rated” wetland with a Category I area adjacent to a lower-rated area.

b.    The buffer is increased adjacent to the higher-functioning area of habitat or more sensitive portion of the wetland and decreased adjacent to the lower-functioning or less sensitive portion.

c.    The total area of buffer after averaging is equal to the area required without averaging.

d.    The buffer at its narrowest point is never less than three-quarters of the required width.

2.    Averaging to allow reasonable use of a parcel may be permitted when all of the following are met:

a.    There are no feasible alternatives to the site design that could be accomplished without buffer averaging.

b.    The averaged buffer will not result in degradation of the wetland’s functions and values as demonstrated by a report from a qualified wetland professional.

c.    The total buffer area after averaging is equal to the area required without averaging.

d.    The buffer at its narrowest point is never less than three-quarters of the required width.

F.    Decreasing Buffer Widths. Per Section 8C.2.4.1 of Appendix 8-C, Wetlands in Washington State—Volume 2, wetland buffer widths required for “high” intensity land uses can be reduced to those required for “moderate” intensity land uses (see Tables 16.20.230.A and 16.20.230.B) under the following conditions:

1.    For wetlands that score moderate or high for habitat (five to nine points for the habitat score), the width of the buffer can be reduced by no more than twenty-five percent if both of the following criteria are met:

a.    A relatively undisturbed, vegetated corridor at least one hundred feet wide is protected between the wetland and any other priority habitats as defined by the Washington State Department of Fish and Wildlife. “Relatively undisturbed” and “vegetated corridor” are defined in the Western Washington Wetland Rating System. Priority habitats within the city may include:

i.    Wetlands;

ii.    Riparian zones;

iii.    Cliffs;

iv.    Estuary/estuary-like;

v.    Marine/estuarine shorelines;

vi.    Biodiversity and corridors. 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.

b.    Measures to minimize the impacts of different land uses on wetlands, such as the examples in Table 16.20.230.C, are applied.

2.    For wetlands that score less than five points for habitat, the buffer width can be reduced by no more than twenty-five percent applying measures to minimize the impacts of the proposed land uses, such as the examples in Table 16.20.230.C.

Table 16.20.230.C—Examples of Measures to Minimize
Impacts to Wetlands from Different Types of Activities 

Examples of Disturbances

Activities and Uses That Cause Disturbances

Examples of Measures to Minimize Impacts

Lights

Parking lots, warehouses, commercial, manufacturing, residential areas

Direct lights away from wetland.

Noise

Manufacturing, commercial, residential areas

Locate activity that generates noise away from wetland.

Toxic runoff*

Parking lots, roads, manufacturing, commercial, residential areas, landscaping

Route all new untreated runoff away from wetland while ensuring wetland is not dewatered.

Establish covenants limiting use of pesticides within 150 feet of wetland.

Apply integrated pest management.

Stormwater runoff

Parking lots, roads, manufacturing, residential areas, commercial, landscaping

Retrofit stormwater detention and treatment for roads and existing adjacent development.

Prevent channelized flow from lawns that directly enter the buffer.

Change in water regime

Impermeable surfaces, lawns, clearing and grading

Infiltrate or treat, detain and disperse into buffer new runoff from impervious surfaces and new lawns.

Pets and human disturbance

Residential areas

Use privacy fencing; plant dense vegetation to delineate buffer edge and to discourage disturbance using vegetation appropriate for the ecoregion; place wetland and its buffer in a separate tract.

Dust

Clearing and grading

Use best management practices to control dust.

*    These examples are not necessarily adequate for minimizing toxic runoff if threatened or endangered species are present.

3.    Decision Criteria. Prior to approval, a buffer reduction proposal shall meet all of the decisional criteria listed below.

a.    It will provide an overall improvement in water quality protection for the wetland; and

b.    It will not adversely affect fish or wildlife species and will provide an overall enhancement to fish and wildlife habitat; and

c.    It will provide a net improvement in drainage and/or stormwater detention capabilities; and

d.    All exposed areas are stabilized with native vegetation, as appropriate; and

e.    It will not lead to unstable earth conditions or create an erosion hazard; and

f.    It will not be materially detrimental to any other property or the city as a whole.

G.    Increasing Buffer Widths. The director 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, per Section 8C.2.5 of Appendix 8-C, Wetlands in Washington State, Volume 2. This determination shall be made only when the director demonstrates any one of the following through appropriate documentation:

1.    The wetland site has known locations of endangered or threatened species, the width of the buffer should be increased to provide adequate protection for the species based on the requirements in Section 8C.2.5.3, as revised, of the Wetlands in Washington State, Volume 2;

2.    The adjacent land is susceptible to severe erosion and erosion control measures alone will not effectively prevent adverse wetland impacts; and

3.    The adjacent land on the development proposal site has minimal vegetative cover or slopes greater than thirty percent.

H.    Building or Impervious Surface Setbacks. A building or impervious surface setback of fifteen feet is required from the edge of any wetland buffer. Minor structural or impervious surface intrusions into the areas of the setback, such as but not limited to fire escapes, open/uncovered porches, landing places, outside walkways, outside stairways, retaining walls, fences and patios, may be permitted if the department determines upon review of an analysis of buffer functions submitted by the applicant, that such intrusions will not adversely impact the wetland. The setback shall be identified on a site plan.

I.    Signs and Fencing of Wetlands. This subsection applies to those wetlands and their buffers that are within three hundred feet of regulated development activities:

1.    Wetland buffers shall be temporarily fenced or otherwise suitably marked, as required by the director, 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.

2.    The director may require that permanent signs and/or fencing be placed on the common boundary between a wetland buffer and the adjacent land. Such signs will identify the wetland buffer and may be required to contain other information related to wetland protection. The director may approve an alternative method of wetland and buffer identification if it provides adequate protection to the wetland and buffer.

J.    Buffer Enhancement Plan. When a buffer is proposed to be averaged, reduced or increased, the applicant shall submit a buffer enhancement plan prepared by a qualified wetland specialist, and in conjunction with a mitigation plan, if required. The report shall assess the habitat, water quality, stormwater detention, groundwater recharge, shoreline protection, and erosion protection functions of the buffer; and assess the effects on those functions. The buffer enhancement plan shall also provide the following:

1.    A map detailing the specific area of enhancement that shows the elevation contours of the site;

2.    A planting plan that uses native plant species indigenous to this region including groundcover, shrubs and trees and designed to provide intensive vegetative planting to result in improved habitat and the screening of the wetland from adjacent disturbances;

3.    Provisions for monitoring and maintenance over the monitoring period as required under Section 16.20.740.

4.    The buffer enhancement plan shall document how the buffer will enhance the functions and values of the wetland. The planting plan shall be reviewed by a third-party consultant hired by the city at the applicant’s expense, or by state resource agency staff person with the appropriate expertise. Such a review will include evaluation of the accuracy and scientific validity of the enhancement plan, and provide written comments including recommendations for additional documentation or revisions. (Ord. 2017-10 § 2 (Exh. A (part)), 2017: Ord. 2007-24 § 2 (part), 2007)

16.20.235 Additional development standards.

In addition to meeting the development standards in Section 16.20.230, the regulated uses identified below shall also comply with the standards of this section and other applicable state, federal and local ordinances.

A.    Docks. Construction of a dock, pier, moorage, float or launch facility may be permitted subject to criteria in the city’s shoreline master program.

B.    Forest Practice, Class IV General, and Conversion Option Harvest Plans (COHPs). All timber harvesting and associated development activity, such as construction of roads, shall comply with the provisions of this chapter, including the maintenance of buffers around regulated wetlands.

C.    Agricultural Restrictions. In all development proposals which would permit introduction or expansion of agricultural uses, damage to regulated wetlands shall be avoided, and will be regulated as a development activity subject to the provisions of this section.

D.    Road/Street Repair and Construction. Public road or street repair, maintenance, expansion or construction may be allowed in wetlands or wetland buffers subject to the following development standards:

1.    No other reasonable or practicable alternative exists and the road or street crossing serves multiple properties wherever possible;

2.    Publicly owned or maintained road or street crossings provide for other purposes, such as utility crossings, pedestrian or bicycle easements, viewing points, etc.;

3.    The road or street repair and construction are the minimum necessary to provide safe roads and streets;

4.    Mitigation shall be performed in accordance with this chapter and specific project mitigation plan requirements; and

5.    Before beginning work in-water or within wetlands, it shall be the responsibility of the agency to ensure that all other required state and federal approvals have been obtained.

E.    Surface Water Management Low Impact Development (LID). A wetland or its buffer can be physically or hydrologically altered to meet the requirements of a stormwater management runoff treatment, LID or flow control best management practices (BMP), if the following criteria are met:

1.    The Category III or IV wetland has a habitat score of three to four points; and no other location is feasible; and

2.    There will be “no net loss” of functions and values of the wetland, and the location of such facilities will not degrade the functions or values of the wetland; and

3.    The wetland does not contain a breeding population of any native amphibian species; and

4.    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 “Guide for Selecting Mitigation Sites Using a Watershed Approach” (http://www.ecy.wa.gov/biblio/0906032.html); 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

5.    The wetland lies in the natural routing of the runoff, and the discharge follows the natural routing; and

6.    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

7.    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.

A site-specific characterization through a wetland report is required to determine if an LID best management practice (BMP) is feasible for a project site and all of the criteria above are met. The special wetland report shall be prepared consistent with Section 16.20.725 and will be verified through peer review.

A wetland hydrology monitoring plan prepared by a qualified wetland specialist shall be required. 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 peer review.

F.    Trails and Trail-Related Facilities. Construction of public trails and trail-related facilities, such as benches and viewing platforms, may be allowed in wetlands or wetland buffers pursuant to the following guidelines:

1.    Trails and related facilities shall, to the extent feasible, be placed on existing road grades, utility corridors, or any other previously disturbed areas outside of the buffer.

2.    Trails and related facilities that are outside of the buffer shall be planned to minimize removal of trees, soil disturbance and existing hydrological characteristics, shrubs, snags and important wildlife habitat.

3.    Viewing platforms and benches, and access to them, shall be designed and located to minimize disturbances of wildlife habitat and/or critical characteristics of the affected wetland.

4.    Trails and related facilities shall generally be located outside required buffers. Where trails are permitted within buffers, they should be located in the outer twenty-five percent of the wetland buffer area as much as feasible, except where wetland crossings or viewing areas have been approved.

5.    Trails shall generally be limited to pedestrian use unless other more intensive uses, such as bike or horse trails, have been specifically allowed and mitigation has been provided. Trail width shall not exceed five feet unless there is a demonstrated need, subject to review and approval by the director. Trails shall be constructed with pervious materials unless otherwise approved by the director and located in the outer twenty-five percent of the wetland buffer area as much as feasible.

6.    Mitigation may be required to replace native vegetation removed for trail construction or enhance remaining areas of degraded buffer.

G.    Utilities in Wetlands or Wetland Buffers.

1.    The utility development authorized in Section 16.20.120 shall be allowed, subject to best management practices in wetlands and wetland buffers.

2.    Construction of new utilities outside the road right-of-way or existing utility corridors or easements may be permitted in wetlands or wetland buffers, only when no reasonable alternative location is available and the utility corridor or easement meets the requirements for installation, replacement or vegetation and maintenance outlined below, and as required in the filing and approval of applicable permits and special reports (Section 700 of this chapter) required by this chapter.

3.    Sanitary Sewer or On-Site Sewage Utility. Construction of sanitary sewer lines or on-site sewage systems may be permitted in regulated wetland buffers only when: (a) 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 (b) there are no other practicable or reasonable alternatives available and construction meets the requirements of this section. Joint use of the sanitary sewer utility easement by other utilities may be allowed.

4.    New utility corridors or easements 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 or easement will not significantly impact the wetland or wetland buffer.

5.    New utility corridor or easement construction and maintenance shall protect the regulated wetland and buffer environment by utilizing the following methods:

a.    New utility corridors or easements shall be aligned when possible to avoid cutting trees greater than twelve inches in diameter at breast height (four and one-half feet), measured on the uphill side.

b.    New utility corridors or easements 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.

c.    Any additional utility corridor or easement 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 fifteen 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.

d.    The director may require other additional mitigation measures.

6.    Utility corridor maintenance shall include the following measures to protect the regulated wetland and buffer environment:

a.    Where feasible, painting of utility equipment such as power towers shall not be sprayed or sandblasted, nor should lead-based paints be used.

b.    No pesticides, herbicides or fertilizers may be used in wetland areas or their buffers except those approved by the EPA and the Department of Ecology. Where approved, herbicides must be applied by a licensed applicator in accordance with the safe application practices on the label.

7.    Before beginning work in-water or within wetlands, it shall be the responsibility of the utility to ensure that all other required state and federal approvals have been obtained. (Ord. 2017-10 § 2 (Exh. A (part)), 2017: Ord. 2016-20 § 2 (Att. A (part)), 2016; Ord. 2012-10 § 5 (Exh. D) (part), 2012; Ord. 2007-24 § 2 (part), 2007)

16.20.240 Wetland alterations.

A.    Mitigation Sequencing. All regulated development activities proposed to impact wetlands or buffers shall be mitigated according to this title subject to the following sequential order (WAC 197-11-768). The applicant shall demonstrate to the satisfaction of the review authority that each step of this sequence has been adequately addressed prior to approving or permitting impacts to wetlands under this chapter.

1.    Avoiding the impact altogether by not taking a certain action or parts of an action;

2.    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;

3.    Rectifying the impact by repairing, rehabilitating, or restoring the affected environment;

4.    Reducing or eliminating the impact over time by preservation and maintenance operations during the life of the action;

5.    Compensating for the impact by replacing, enhancing or providing substitute resources or environments;

6.    Monitoring the impact and taking appropriate corrective measures; or

7.    Mitigating for individual actions may include a combination of the above measures.

B.    Mitigation for Regulated Activities in Wetland Buffers. A specific mitigation plan is required and the requirements are provided in Section 16.20.725. Appropriate implementation and timing of the mitigation plan shall be included as conditions of approval of the underlying land use permit.

C.    Mitigation for Regulated Activities in Wetlands. Compensatory mitigation shall be required for regulated activities that result in the loss of wetland acreage or in the reduction of wetland functions or habitat values. A specific mitigation plan is required and the requirements are provided in Section 16.20.725.

1.    A compensatory mitigation plan shall be completed. The applicant shall submit a detailed mitigation plan for compensatory mitigation to the department.

2.    The detailed mitigation plan shall be prepared, signed, and dated by the wetlands specialist to indicate that the plan is in accordance with specifications as determined by the wetlands specialist. A signed original mitigation plan shall be submitted to the department.

3.    Approval of the detailed mitigation plan shall be signified through conditions of approval of the underlying land use permit and requiring appropriate implementation and timing of the mitigation plan.

4.    The mitigation project shall be completed according to a schedule agreed upon between the department and the applicant as included in the wetland mitigation plan and conditions of approval.

5.    Wetland mitigation shall occur according to the approved wetland mitigation plan and shall be consistent with provisions of this chapter and title.

6.    A wetlands specialist shall be on site during construction and plant installation phases of all mitigation projects.

7.    On completion of construction for the wetland mitigation project, the wetlands specialist shall submit an as-built report to the department for review and approval.

D.    Wetland Replacement Ratios.

1.    The ratios presented here are based on the type of compensatory mitigation proposed (restoration, creation/establishment, or enhancement). These types of compensatory mitigation, listed in order of preference, are defined as follows:

a.    Restoration. The manipulation of the physical, chemical, or biological characteristics of a site with the goal of returning natural or historic functions to a former or degraded wetland. For the purpose of tracking net gains in wetland acres, restoration is divided into:

i.    Reestablishment. The manipulation of the physical, chemical, or biological characteristics of a site with the goal of returning natural or historic functions to a former wetland. Activities could include removing fill material, plugging ditches, or breaking drain tiles. Reestablishment results in a gain in wetland acres and functions.

ii.    Rehabilitation. The manipulation of the physical, chemical, or biological characteristics of a site with the goal of repairing natural or historic functions of a degraded wetland. Activities could involve breaching a dike to reconnect wetlands to a floodplain or return tidal influence to a wetland. Rehabilitation results in a gain in wetland function but does not result in a gain in wetland acres.

b.    Creation/Establishment. The manipulation of the physical, chemical, or biological characteristics present to develop a wetland on an upland or deepwater site, where a wetland did not previously exist. Activities typically involve excavation of upland soils to elevations that will produce a wetland hydroperiod, create hydric soils, and support the growth of hydrophytic plant species. Establishment results in a gain in wetland acres.

c.    Enhancement. The manipulation of the physical, chemical, or biological characteristics of a wetland site to heighten, intensify or improve specific function(s) or to change the growth stage or composition of the vegetation present. Enhancement is undertaken for specified purposes such as water quality improvement, floodwater retention or wildlife habitat. Activities typically consist of planting vegetation, controlling nonnative or noxious weeds (Class A and B), modifying site elevations or the proportion of open water to influence hydroperiods, or some combination of these. Enhancement results in a change in some wetland functions and can lead to a decline in other wetland functions, but does not result in a gain in wetland acres.

d.    Preservation. The removal of a threat to, or preventing the decline of, wetland conditions by an action in or near a wetland. This term includes the purchase of land or easements, repairing water control structures or fences, or structural protection. Preservation does not result in a gain of wetland acres (but may result in a gain in functions over the long term). Replacement ratios for preservation will be determined on a case-by-case basis, depending on the quality of the wetlands being lost or degraded and the quality of the wetlands being preserved.

2.    The following ratios appearing below in Table 16.20.240, Wetland Mitigation Replacement Ratios, as found in Wetland Mitigation in Washington State—Part 1: Agency Policies and Guidance (Ecology Publication No. 06-06-011a). These ratios shall be used to determine the appropriate amounts of restored, established, or enhanced wetland that will be required to replace impacted wetlands. The first number specifies the amount of wetland area requiring restoration, establishment, or enhancement and the second number specifies the amount of wetland area altered.

*    Due to the dynamic nature of interdunal systems, enhancement is not considered an ecologically appropriate action.

**    Natural heritage sites, coastal lagoons, and bogs are considered irreplaceable wetlands because they perform some special functions that cannot be replaced through compensatory mitigation. Impacts to such wetland would therefore result in a net loss of some functions no matter what kind of compensation is proposed.

3.    The director may increase or decrease the ratios based on one or more of the following:

a.    Replacement ratios may be increased under the following circumstances:

i.    Uncertainty exists as to the probable success of the proposed restoration or creation;

ii.    A significant period of time will elapse between impact and establishment of wetland functions at the mitigation site;

iii.    Proposed compensation will result in a lower category wetland or reduced functions relative to the wetland being impacted; or

iv.    The impact was an unauthorized impact.

b.    Replacement ratios may be decreased under the following circumstances:

i.    Documentation by a wetland specialist demonstrates that the proposed compensation actions have a very high likelihood of success based on prior experience. For example, demonstrated prior success with similar compensation actions as those proposed, and/or extensive hydrologic data to support the proposed water regime;

ii.    Documentation by a qualified wetland specialist demonstrates that the proposed compensation actions will provide functions and values that are significantly greater than the wetland being impacted; or

iii.    The proposed mitigation actions are conducted in advance of the impact and are shown to be successful.

c.    Compensatory mitigation should not result in the creation, restoration or enhancement of an atypical wetland. An atypical wetland is defined as a wetland whose design does not match the type of wetland that would be found in the geomorphic setting of the proposed site (i.e., the water source(s) and hydroperiod proposed for the mitigation site are not typical for the geomorphic setting). Any designs that provide exaggerated morphology (such as excavating a permanently inundated pond in a seasonally saturated or inundated wetland) or require a berm or engineered structures to hold back water would be considered atypical.

E.    Compensatory Mitigation. Unless it is demonstrated that a higher level or ecological functioning would result from an alternative approach, compensatory mitigation for ecological functions shall be in-kind and either on-site, or within the same stream reach, sub-basin, or drift cell (if estuarine wetlands are impacted). Compensatory 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:

1.    There are no reasonable on-site or in-sub-drainage-basin opportunities (e.g., on-site options would require elimination of high-functioning upland habitat), or on-site and in-sub-drainage-basin opportunities do not have a high likelihood of success based on a determination of the capacity of the site to compensate for the impacts; and

2.    Off-site mitigation has a greater likelihood of providing equal or improved wetland functions than the impacted wetland; and

3.    Off-site locations shall be in the same sub-drainage basin unless:

a.    Established watershed goals for water quality, flood storage or conveyance, habitat, or other wetland functions have been established by the city or Kitsap County and strongly justify location of mitigation at another site;

b.    Credits from a state-certified wetland mitigation bank are used as compensation and the use of credits is consistent with the terms of the bank’s certification; or

c.    Fees are paid to an approved in-lieu-fee program to compensate for the impacts.

F.    Advance Mitigation. Compensatory mitigation in advance of proposed impacts may be allowed on a case-by-case basis where the applicant demonstrates consistency with approved state and/or federal advance mitigation programs and policies. Approval of an advance mitigation plan is not a guarantee of future project approval or authorization.

G.    Monitoring Requirements. The city of Poulsbo shall require monitoring reports on an annual basis for a minimum of five years and up to ten years, or until the director determines that the mitigation project has met the performance standards specified in the wetland mitigation plan. The wetland mitigation plan shall provide specific performance standards for monitoring the mitigation project. The performance standards shall be project-specific and use best available science to aid the director in evaluating whether or not the project has achieved success. (Ord. 2017-10 § 2 (Exh. A (part)), 2017: Ord. 2007-24 § 2 (part), 2007)

16.20.315 Development standards.

The following development standards shall apply to fish and wildlife habitat conservation areas:

A.    Buffers and Setbacks. Buffers and building setbacks shall be maintained along all identified fish and wildlife habitat conservation areas, as indicated in this section.

1.    Buffers and building setbacks shall be maintained along all identified fish and wildlife habitat conservation areas. Distances shall be measured horizontally from the ordinary high water mark (OHWM) or from the top of the bank where the OHWM cannot be identified. Building setbacks shall be measured horizontally from the edge of the buffer.

a.    For streams in ravines with ravine sides ten feet or greater in height, the minimum buffer width shall be the minimum required or a width which extends twenty-five feet beyond the top of the slope, whichever is greater.

2.    Buffers shall be retained in at least the quality of their existing condition. Where impacts or reductions of the standard buffer width are proposed, the director may require the remaining buffer be enhanced to protect the quality and function of the fish and wildlife habitat conservation area through a buffer enhancement plan. Refuse, including but not limited to household trash, yard waste, and commercial/industrial refuse, shall not be placed in the buffer.

3.    Stream buffers shall include streamside wetlands and/or functional floodplains which provide overflow storage for stormwaters, provide groundwater recharge or discharge functions, or provide seasonal shelter and food for fish. In braided channels, the OHWM or top of bank shall be defined so as to include the entire stream feature.

4.    Where wetlands and geologically hazardous areas occur on a site that contains a fish and wildlife habitat conservation area, refer to Sections 200, Wetlands, and 400, Geologically Hazardous Areas, of this chapter for additional development standards. In cases of differing standards, the more restrictive buffer or setback shall apply.

5.    Building Setbacks. An additional building setback of twenty-five feet is required from the edge of all fish and wildlife habitat conservation area buffers.

a.    If applicable, the required building setbacks may meet or contribute to specific yard setback requirements of Title 18.

b.    Minor structural or impervious surface intrusions such as but not limited to fire escapes, open/uncovered porches, landing places, outside walkways, outside stairways, retaining walls fences, and patios may be permitted within the required building setback if the director determines, upon submittal of a habitat management plan, that such intrusions will not adversely impact the fish and wildlife habitat conservation area or its buffer. The setback shall be identified on the site plan or appropriate drawing.

6.    New Development or Redevelopment. Standard buffers and building setbacks for fish and wildlife habitat conservation areas shall be required as per Table 16.20.315.

(i) Require on-site infiltration of stormwater, where soils are appropriate, for new construction; establish downspout disconnection program for existing development.

* Main stem segment also subject to shoreline regulations in Chapter 16.08 as appropriate.

Other Fish and Wildlife Habitat Conservation Areas

Buffer widths and building setbacks for other regulated fish and wildlife habitat conservation areas not listed above will be determined on a case-by-case basis through a habitat management plan, which shall be based upon the most recent WDFW Priority Habitat and Species Management Recommendations.

B.    Changes to Standard Buffers.

1.    Provisions for Decreasing the Standard Buffers Recommended through a Habitat Management Plan.

a.    The director may decrease the standard buffer or building setback as recommended by a habitat management plan after consultation with the Washington State Department of Fish and Wildlife and the Suquamish Tribe, and determine that conditions are sufficient to protect the affected habitat. A habitat management plan shall be required. The director may reduce the buffer or building setback width by up to twenty-five percent, but the buffer width shall not be less than fifty feet.

2.    Provisions for Increasing Standard Buffers. The director may increase the buffer width whenever a specific development proposal has 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.

3.    Conditional Alterations. The director may alter the standard buffer, and building setback for water-dependent structures and utilities within a stream or its buffer when no other reasonable or practical alternative exists. Any alteration of a buffer or building setback shall be the least necessary and shall require a habitat management plan which identifies and adequately protects any affected fish and wildlife conservation area.

C.    Fish and wildlife habitat conservation areas and required buffers shall be located within specified open space tracts. The specified open space tracts shall be identified on the underlying land use permit drawings and conditions of approval shall include provisions for preservation, maintenance and other requirements deemed necessary by the director and/or review authority.

D.    All development permits on sites with known locations of fish and wildlife habitat conservation areas, or sites within three hundred feet to known locations of fish and wildlife habitat conservation areas, shall submit a habitat assessment or management plan as specified in Section 700 of this chapter for approval. In the case of bald eagles, an approved bald eagle management plan by the Washington Department of Fish and Wildlife, meeting the requirements and guidelines of the bald eagle protection rules (WAC 220-610-100), as now or hereafter amended, shall satisfy the requirements for a habitat management plan.

E.    Habitat Assessment Report and Management Plan. For all regulated activity proposed on a site which contains or is within three hundred feet of fish and wildlife habitat conservation area, a habitat assessment shall be prepared by a qualified wildlife biologist. The habitat assessment shall identify the type of stream and its prescribed buffer, an analysis of species or habitats known or suspected, and assessment of project impact or effect on habitat and water quality (see Section 16.20.750). If it is determined that a fish and wildlife habitat conservation area or its buffer does not occur on or within three hundred feet of the site, or if it is demonstrated that the project will comply with the standard buffer width and building setback requirements, the development may proceed without any additional requirements under this section. If it is determined that a fish and wildlife habitat conservation area does occur on or within three hundred feet of the site, and a modification (i.e., reduction, intrusion or impact) to the standard buffer width and/or building setback is proposed, a habitat management plan shall be prepared. (See Section 16.20.730.)

F.    Signs and Fencing. As a project condition of approval, the director or review authority may require the fish and wildlife habitat conservation area and buffer be permanently fenced, signed or an acceptable alternative, to further protect the conservation area. Timing, location and type of installation shall be identified in the condition of approval. Fencing shall be required when reductions of buffer or intrusions into building setback are approved.

G.    Provisions for Expansions of Existing Development along Poulsbo Creek. Existing development adjacent to Poulsbo Creek which was lawfully constructed, approved or established prior to the effective date of the ordinance codified in this chapter, but which does not conform to present regulations or standards, may be expanded as follows:

1.    A nonconforming single-family residence or mobile home may be enlarged up to fifty percent of its existing size as long as:

a.    The new construction extends away from the critical area and related buffer and building setback, is located over an existing impervious area, or is a second/third-story addition located over the existing structure;

b.    The reconstruction and/or enlargement shall be appropriately mitigated to ensure the existing value and function of the critical area is not degraded;

c.    Mitigation and enhancement is required as per subsection (G)(2) of this section;

d.    The structure(s) are located outside of a flood hazard area and active landslide hazard area; and

e.    The reconstruction and/or enlargement meets all other dimensional standards and requirements contained in the Poulsbo Municipal Code.

2.    Requirements for mitigation and enhancement will be determined based on historic site impacts to the critical area, the scope of proposed alterations and require the preparation of a habitat management plan. Possible mitigation and enhancement may include, but shall not be limited to: prohibiting or limiting pruning of riparian vegetation; invasive plant removal and reestablishment of native trees and shrubs within existing buffer areas; instream habitat improvements such as spawning gravel or large woody debris; requiring minimum stormwater treatment for new construction; and retrofitting existing impervious areas with minimum stormwater treatment where feasible. In certain instances, off-site mitigation and/or enhancement may also be required to benefit the watershed.

3.    Proposals that proposed to utilize these requirements shall require a critical area permit, a Type II review. (Ord. 2017-10 § 2 (Exh. A (part)), 2017: Ord. 2012-10 § 5 (Exh. D) (part), 2012; Ord. 2007-24 § 2 (part), 2007)

16.20.320 Project-specific development standards.

A.    Stream Crossings. Any private or public road expansion or construction which is allowed and must cross streams classified within this chapter shall comply with the following minimum development standards:

1.    Bridges or bottomless culverts shall be required for all streams which support fish life, unless a habitat management plan is submitted which demonstrates that other alternatives would not result in significant impacts to the fish and wildlife habitat conservation area and as determined appropriate through the Hydraulic Project Approval process administered by the Washington State Department of Fish and Wildlife;

2.    Crossings shall not occur in salmonid spawning areas unless no other feasible crossing site exists. For new development proposals, if existing crossings are determined to adversely impact salmon spawning or passage areas, new or upgraded crossings shall be located as determined necessary through coordination with the Washington Department of Fish and Wildlife;

3.    Bridge piers or abutments shall not be placed in either the floodway or between the ordinary high water marks unless no other feasible alternative placement exists;

4.    Crossings shall not diminish flood-carrying capacity;

5.    Crossings shall serve multiple properties whenever possible;

6.    Publicly owned or maintained road or street crossing shall provide for other purposes, such as utility crossing, pedestrian or bicycle easements, viewing points, whenever possible;

7.    Where there is no reasonable alternative to providing a conventional culvert, the culvert shall be the minimum length necessary to accommodate the permitted activity. If located on a stream containing fish and wildlife habitat per WAC 222-16-030, the culvert shall be designed in accordance with the Washington Department of Fish and Wildlife’s 2013 Water Crossing Guidelines (or as amended).

B.    Stream Relocations. Stream relocations for the purpose of flood protection and/or fisheries restoration shall only be permitted when adhering to the following minimum performance standards and when consistent with Washington State Department of Fish and Wildlife’s Hydraulic Project Approval, and any other local, state or federal permits:

1.    The channel, bank and buffer should be replanted with native vegetation that replicates a natural, undisturbed riparian condition;

2.    For those shorelands and waters prone to flooding, a professional engineer licensed in the state of Washington shall provide information demonstrating that the equivalent base flood storage volume and function will be maintained;

3.    Relocated stream channels shall be designed to meet or exceed the functions and values of the stream to be relocated; and

4.    Relocation proposal shall include an evaluation report addressing potential downstream impacts to public and private properties, critical areas and listed species; changes to hydroperiod, water quality, flooding frequency or severity; and any necessary downstream stormwater facility improvements associated with the relocation.

C.    Pesticides, Fertilizers and Herbicides. No pesticides, herbicides or fertilizers may be used in fish and wildlife habitat conservation areas or their buffers, except those approved by the EPA and approved under a DOE water quality modification permit for use in the specific fish and wildlife habitat conservation area environments. Where approved, herbicides must be applied by a licensed applicator in accordance with the safe application practices on the label.

D.    Agricultural Restrictions. In all development proposals or activities which would permit introduction of agriculture to fish and wildlife habitat conservation areas, damage to the area shall be avoided by installation of fencing located not closer than the outer buffer edge.

E.    Poulsbo Shoreline Master Program. All development along the saltwater shoreline defined as shorelines of the state shall be consistent with the city of Poulsbo shoreline master program, as now or hereafter amended.

F.    Trails and Trail-Related Facilities. Construction of public and private trails and trail-related facilities, such as benches, interpretative centers, and viewing platforms, may be allowed in fish and wildlife habitat conservation areas or buffers pursuant to the following standards:

1.    Trails and related facilities shall, to the extent feasible, be placed on existing road grades, utility corridors, or other such previously disturbed areas outside of required buffers;

2.    Trails and related facilities shall be planned to be located generally outside of required buffers, and minimize removal of trees, shrubs, snags and important wildlife habitat;

3.    Viewing platforms, interpretive centers, benches and access to them shall be designed and located to minimize disturbance of wildlife habitat and/or critical characteristics of the affected conservation area;

4.    Trails and related facilities shall generally be located outside required buffers. Where trails are permitted within buffers, after exhausting items of subsections (F)(1), (2) and (3) of this section, shall be located in the outer twenty-five percent of the buffer as feasible, except where stream crossings or viewing areas have been approved;

5.    Trails shall generally be limited to pedestrian use unless other more intensive uses, such as bike or horse trails, have been specifically allowed and mitigation has been provided. Trail width shall not exceed five feet unless there is a demonstrated need, subject to review and approval by review authority. Trails shall be constructed with pervious materials unless otherwise approved by the review authority and located in the outer twenty-five percent of the buffer area as much as feasible.

6.    Mitigation may be required to replace native vegetation removed for trail construction or enhance remaining areas of degraded buffer.

7.    Stormwater controls may be required for larger, paved trails.

8.    Trails shall be located only with property owner agreement. If proposed as a public trail, access shall be executed by appropriate easements, dedication, acquisition or other acceptable legal mechanisms.

G.    Utilities. Placement of utilities within designated fish and wildlife habitat conservation areas and buffers may be allowed pursuant to the following standards:

1.    The utility development authorized in Section 16.20.120 shall be allowed, subject to best management practices in fish and wildlife habitat conservation areas and buffers.

2.    Construction of new utilities outside the road right-of-way or existing utility corridors or easements may be permitted in fish and wildlife habitat conservation areas or their buffers, only when no reasonable alternative location is available and the utility corridor or easement 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 (Section 700 of this chapter) required by this chapter.

3.    Sewer or On-Site Sewage Utility. Construction of sewer lines or on-site sewage systems may be permitted in fish and wildlife habitat conservation areas or their buffers when the applicant demonstrates it is necessary to meet state and/or local health code requirements, there are no other practicable alternatives available, and the construction meets the requirements of this section. Joint use of the sewer utility corridor by other utilities may be allowed.

4.    New utility corridors or easements shall not be allowed in fish and wildlife habitat conservation areas with 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 or easement will not significantly impact the fish and wildlife habitat conservation areas or buffers.

5.    New utility corridor or easement construction and maintenance shall protect the environment of fish and wildlife habitat conservation areas and their buffers.

a.    New utility corridors or easements shall be aligned when possible to avoid cutting trees greater than twelve inches in diameter at breast height (four and one-half feet), measured on the uphill side.

b.    New utility corridors or easements 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.

c.    Any additional utility corridor or easement 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 fifteen feet; and shall be contiguous to the location of the utility corridor on the side away from the fish and wildlife habitat conservation area. Mitigation will be required for any additional access through restoration of vegetation in disturbed areas.

d.    The director may require other additional mitigation measures.

6.    Utility corridor maintenance shall include the following measures to protect the regulated fish and wildlife habitat conservation area and buffer environment:

a.    Where feasible, painting of utility equipment such as power towers shall not be sprayed or sandblasted, nor should lead-based paints be used.

b.    No pesticides, herbicides or fertilizers may be used in fish and wildlife habitat conservation areas or their buffers except those approved by the EPA and the Department of Ecology. Where approved, herbicides must be applied by a licensed applicator in accordance with the safe application practices on the label.

c.    Refueling or maintenance of utility equipment shall not be conducted within a fish and wildlife habitat conservation area or its buffer.

H.    Bank Stabilization. A stream channel and bank may be stabilized when naturally occurring earth movement threatens existing structures (defined as requiring a building permit pursuant to the International Building Code), public improvements, unique natural resources, public health, safety or welfare, or is the only feasible access to property; and when such stabilization results in maintenance of fish and wildlife habitat, flood control and improvement of water quality. Shoreline stabilization is regulated by the city’s shoreline master program.

When bank stabilization is determined to be necessary, bioengineering or other nonstructural methods should be the first option for protection. The director may require that bank stabilization be designed by a professional engineer licensed in the state of Washington with demonstrated expertise in hydraulic actions. Bank stabilization projects may also require a Hydraulic Project Approval from the Washington Department of Fish and Wildlife and may be required to meet the design guidelines in WDFW’s 2002 Integrated Streambank Protection Guidelines.

Section 400. Geologically Hazardous Areas

16.20.405 Purpose.

This section applies to all regulated uses included in this chapter within three hundred feet of areas designated as geologically hazardous areas, as defined or identified in WAC 365-190-030 and 365-190-120, and as categorized in Section 16.20.410. The intent of this section is to:

A.    Approval. The director will review all submittals for clearing, grading and building on property containing geologically hazardous areas or areas of geologic concern. The director will consider any proposed mitigation measures included in a geotechnical report, if submitted. In cases where a special report indicates a significant risk to public health, safety or welfare, the city shall deny or require revision of the application.

B.    City Engineer Requirements. The city engineer, in conjunction with a clearing, grading or building permit application in geologically hazardous areas or areas of geologic concern, may require, 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 that address the potential concerns and mitigations for development in geologically hazardous area or area of geologic concern.

C.    Required Buffer. A standard buffer of twenty-five feet shall be established from the top, toe, and all edges of geologically hazardous areas and areas of geologic concern, unless otherwise specified through a geological report or site-specific determination. Existing vegetation shall be retained, or the buffer shall be replanted with appropriate native vegetation.

D.    Buffer and Building Setback Modifications. The minimum native vegetative buffer and/or building setback requirement may be decreased if a geotechnical report demonstrates that a lesser distance, and the design and engineering, will adequately protect the proposed development and stabilize the potential hazard.

Should the report indicate a greater buffer and/or building setback than required by this section, the greater buffer and/or building setback shall be required.

E.    Time Limitations. For new or redevelopment, clearing and grading may be limited by the city engineer to the period between May 1st and 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 identifies methods of erosion control for wet weather conditions.

F.    Field Marking Requirements. For new or redevelopment, the proposed clearing for the project and all critical area buffers shall be required to be marked in the field for inspection and approval by the city prior to beginning work. Field marking shall remain in place until construction is completed and final approval is granted by the city. The requirement for field marking will be identified as a condition of approval for the underlying development permit.

G.    Trees and Vegetation. The following requirements apply in geologically hazardous areas and areas of geologic concern:

1.    As a development permit condition, the director may require enhancement of native buffer vegetation and trees to increase protection of the hazard area by stabilizing slopes and preventing soil erosion. A management plan shall be prepared for such enhancement, and the installation shall require maintenance bonding for a minimum of five years to ensure that performance standards have been met.

2.    Removal of danger trees is allowed only if such activity is approved by the director, and requires a written determination by a certified arborist in the state of Washington that the trees proposed for elimination represent a legitimate safety hazard. The director may require that stumps and root systems be retained for soil retention and erosion control.

3.    Minor pruning of vegetation may be allowed only if such activity is approved by the director and is conducted according to a plan prepared by a certified arborist in the state of Washington and peer reviewed and approved by the city arborist.

H.    Roads and Utilities.

1.    Only the clearing necessary to install temporary erosion control measures will be allowed prior to clearing for roads and utilities construction;

2.    Clearing for roads and utilities shall be the minimum necessary and shall remain within marked construction limits;

3.    Clearing for overhead power lines shall be the minimum necessary for construction and will provide the required minimum clearances of the serving utility; and

4.    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 conversion option harvest plan forest practices application.

I.    Seismic Hazard Areas Standards. Applications for new or redevelopment within seismic hazard areas may be required to provide 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 International Building Code. (Ord. 2017-10 § 2 (Exh. A (part)), 2017: Ord. 2007-24 § 2 (part), 2007. Formerly 16.20.415)

Section 500. Critical Aquifer Recharge Areas

16.20.505 Purpose.

The intent of this section 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. (Ord. 2017-10 § 2 (Exh. A (part)), 2017: Ord. 2007-24 § 2 (part), 2007)

16.20.510 Critical aquifer recharge area categories.

A critical aquifer recharge area (CARA) is a geographic area with a critical recharging effect on aquifers used for potable water, including areas where an aquifer that is a source of drinking water is vulnerable to contamination that would affect the potability of the water, or is susceptible to reduced recharge (WAC 365-190-030). CARAs are established according to the following categories:

A.    Wellhead Protection Zones.

1.    The area inside the one-year time of travel zone for Group A water system supply wells, calculated in accordance with the Washington State Wellhead Protection Program.

2.    For Group A water system supply wells, five-year time of travel zones in wellhead protection areas are also included as critical aquifer recharge areas 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 (B)(1) of this section, without an underlying protective impermeable layer.

B.    Aquifer Recharge Areas of Concern. Aquifer recharge areas of concern (ARAC) are those areas which provide recharge to current or potential potable water supplies and are vulnerable to contamination, and meet any one of the following criteria:

1.    Highly Permeable Soils. 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.

The general location and characteristics of soils are identified in the Soil Survey of Kitsap County. The following soil types are considered to have relatively high permeability and are aquifer recharge areas of concern:

Poulsbo/Ragner

41, 42, 43, 44, 45, 46, 47

2.    Areas above Shallow Principal Aquifers. Surface areas above shallow principal aquifers 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.

3.    Areas with High Concentration of Group B Water System Wells and Private Domestic Wells. Locations with well concentrations of thirty-six map units or more within a one-mile radius of the proposed land use. (Ord. 2017-10 § 2 (Exh. A (part)), 2017: Ord. 2007-24 § 2 (part), 2007)

16.20.515 Development standards.

A.    Wellhead Protection Zones. Land uses identified in Table 16.20.515 shall require a hydrogeological report (see Section 700 of this chapter, Special Reports). The hydrogeological report shall include a detailed risk-benefit analysis that considers credible, worst-case scenarios, and shall evaluate potential impacts of a proposed land use or activity on both groundwater and surface water quality. Uses listed in Table 16.20.515 may only be permitted where the applicant can demonstrate that the proposed activity will not cause contaminants to enter the aquifer and that the proposed activity will not adversely affect the recharging of groundwater.

1.    Land uses or activities for new development that pose a significant hazard to the city’s groundwater resources are prohibited and include (but are not limited to): landfills, wood treatment facilities, chrome platers, tank farms, facilities that treat, store, or dispose of hazardous waste, and chemical facilities that transfer or use large amounts of chemicals.

B.    Aquifer Recharge Areas of Concern.

1.    Applicants proposing operations that pose a potential threat to groundwater as listed in Table 16.20.515 in aquifer recharge areas of concern may be required to submit a hydrogeological report (see Section 700 of this chapter, Special Reports). The scope of the report shall be based on site-specific conditions.

2.    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.    Notification and Review.

1.    Affected water purveyors, tribes and the Kitsap County health district will be notified and invited 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.

2.    The department will also notify the health district and affected water purveyors through the environmental review process, when those development activities listed in Table 16.20.515 are proposed outside the areas designated critical aquifer recharge areas.

D.    Stormwater.

1.    Stormwater treatment and infiltration shall be required where soils permit and is determined feasible.

2.    Low impact development best management practices (BMP) are required for smaller developments exempted from requirements to construct stormwater facilities.

E.    Uses Requiring County, State or Federal Approval. Applicants shall provide the department with documentation of compliance with county, state and/or federal regulations associated with uses listed in Table 16.20.515.

16.20.735 Wetland mitigation plan.

Whenever the director has determined that impacts to regulated wetlands or buffers are necessary and unavoidable, or a review of a regulated wetland or its buffer is proposed, or a reasonable use exception is applied, a mitigation plan shall be prepared:

A.    The applicant shall demonstrate that mitigation sequencing was applied to the project, in the following order:

1.    Avoiding the impact altogether by not taking a certain action or parts of actions. This may be accomplished by selecting a practicable alternative that does not involve wetlands or buffer impacts. The applicant must describe practicable alternatives to the project that avoid environmental impacts, and provide valid reasoning why those alternatives would not fulfill the purpose and need of the project.

2.    Minimizing impacts by limiting the degree of 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 design alternative that avoids most environmental impacts, and minimizes others to the greatest extent possible.

3.    Rectifying the impact by repairing, rehabilitating, or restoring the affected environment. This may be accomplished by restoring the environmental functions of an area temporarily affected by a project.

4.    Reducing or eliminating the impact over time by preservation and maintenance operations during the life of the action. This may be done through operational constraints and/or modifications which result in the reduction or elimination of impacts over time. This typically is done in conjunction with other mitigating actions.

5.    Compensating for the impact by replacing, enhancing, or providing substitute resources or environments. This may be done by intentionally creating wetlands and wetland buffers at another location where none currently exist, improving existing wetlands and wetland buffers at another location, or otherwise providing a substitute wetland resource at another location as compensation for any unavoidable adverse wetland impacts. Compensation shall be accomplished in accordance with a mitigation plan, as prepared in accordance with the requirements outlined below, and as approved by the director.

6.    Monitoring the impact and taking appropriate corrective measures.

7.    Mitigating for individual actions may include a combination of the above measures.

B.    The overall goal of any mitigation plan shall be no net loss of regulated wetland functions and acreage.

C.    Those persons proposing wetland compensatory projects shall show that the compensation project is associated with an activity or development otherwise permitted and that the restored, created, or enhanced wetland will be as persistent as the wetland it replaces by accomplishing the following:

1.    Demonstrate sufficient scientific expertise, supervisory capability, and financial resources to carry out the project;

2.    Demonstrate the capability for monitoring the site and for making corrections during this period, if the project fails to meet the stated goals and objectives; and

3.    Protect and manage or provide for the protection and management of the compensation area to avoid further development or degradation.

D.    Wetland mitigation plans shall be implemented by the project applicant, and include the following components:

1.    Baseline Information. A written assessment and accompanying maps of the impacted wetland shall be produced by the applicant or applicant’s consultant and shall include, at a minimum: existing wetland acreage; vegetative, faunal and hydrologic characteristics; soil and substrate conditions; and topographic elevations.

2.    If the compensation site is off site from the impacted wetland site, baseline information about it, in addition to the above information about the impacted wetland, shall be provided by the applicant and shall include existing wetland acreage; vegetative, faunal and hydrologic characteristics; soil and substrate conditions; and topographic elevations; the relationship of the compensation site within the watershed and to existing water bodies; detailed description of the site selection process and valid rationale for the selected site; existing and proposed compensation site conditions; buffers; and ownership.

3.    Environmental Goals and Objectives. The report shall identify goals and objectives and include:

a.    The purposes of the compensation measures, including identification of compensation goals, identification of target evaluation species and resource functions, dates for beginning and completion of compensation measures, and a complete description of structure and functional relationships sought in the new wetland. The goals and objectives shall be related to the functions of the original wetland or, if out-of-kind, the type of wetland to be emulated; and

b.    A review of the available literature and/or experience to date in restoring or creating the type of wetland proposed shall be provided. An analysis of the likelihood of success of the compensation project at duplicating the original wetland shall be provided based on the experiences of comparable projects, if any. An analysis of the likelihood of persistence of the created or restored wetland shall be provided based on such factors as: surface and groundwater supply and flow patterns; dynamics of the wetland ecosystem; sediment or pollutant influx and/or erosion; periodic flooding and drought, etc.; presence of invasive flora and fauna; potential human or animal disturbance; and previous comparable projects, if any.

c.    Performance Standards. Specific criteria shall be provided for evaluating whether or not the goals and objectives of the mitigation plan are being achieved at various stages in the project and for beginning adaptive management or contingency measures. Such criteria may include water quality standards, survival rates of planted vegetation, species abundance and diversity targets, habitat diversity indices, or other ecological, geological or hydrological criteria.

d.    Detailed Construction and Planting Plans. Written specifications and descriptions of compensation techniques shall be provided including the proposed construction sequence, grading and excavation details, erosion, sediment and stormwater recharge control features needed for wetland construction and long-term survival; a planting plan specifying plant species, quantities, locations, size, spacing and density; the source of plant materials, propagules, or seeds; water and nutrient requirements for planting; where appropriate, measures to protect plants from predation; specification of substrate stockpiling techniques and plating instructions; descriptions of water control structures and water-level maintenance practices needed to achieve the necessary hydrocycle/hydroperiod characteristics; etc. These written specifications shall be accompanied by detailed site diagrams, scaled cross-sectional drawings, topographic maps showing slope percentage and final grade elevations, and any other drawings appropriate to show construction techniques of anticipated final outcome. The plan shall provide for elevations which are appropriate for the desired habitat type(s) and which provide sufficient tidal prism and circulation data.

e.    Monitoring Program. A program outlining the approach for monitoring construction of the compensation project and for assessing a completed project shall be provided. Monitoring must include sufficient information to adequately assess the progress of a project. Monitoring may include, but is not limited to: (i) establishing vegetation plots to track changes in plant species composition and density over time; (ii) using photo stations to evaluate vegetation community response; (iii) sampling surface and subsurface waters to determine pollutant loading and changes from the natural variability of background conditions (pH, nutrients, heavy metals); (iv) measuring base flow rates and stormwater runoff to model and evaluate water quantity predictions by a licensed engineer in the state of Washington, where required; (v) measuring sedimentation rates, if applicable; and (vi) sampling fish and wildlife populations to determine habitat utilization, species abundance and diversity. A protocol shall be included outlining how the monitoring data will be evaluated to track the progress of the compensation project. A monitoring report shall be submitted annually, and at a minimum, document milestones, successes, problems, maintenance and contingency actions of the compensation project. The compensation project shall be monitored for a period necessary to establish that performance standards have been met, but not for a period of less than five years, and a longer period may be required if recommended by the mitigation plan or peer review.

f.    Contingency Plan. Identification of potential courses of action, and any corrective measures to be taken, when monitoring or evaluating indicates project performance standards are not being met.

g.    Performance Conditions. Any compensation project prepared pursuant to this section and approved by the department shall become part of the application for the permit.

For all regulated activity proposed on a site which contains or is within three hundred feet of a fish and wildlife habitat conservation area, a habitat assessment shall be prepared by a qualified wildlife biologist. The habitat assessment shall include, at a minimum, the following:

A.    Identify the type of stream and its prescribed buffer.

B.    An analysis and discussion of species or habitats known or suspected to be located within three hundred feet of the site.

C.    Assessment of project impact or effect on habitat and water quality.

D.    A site plan which clearly delineates the fish and wildlife habitat conservation area found on or within three hundred feet of the site. (Ord. 2017-10 § 2 (Exh. A (part)), 2017)

16.20.755 Habitat management plan.

A.    When intrusions, reductions, alterations or impacts to a fish and wildlife habitat conservation area is proposed, or when otherwise required, a habitat management plan shall be prepared. The habitat management plan shall identify how the development impacts from the proposed project will be mitigated. The Washington Department of Fish and Wildlife Priority Habitat and Species Management Recommendations, dated May 1991, or bald eagle protection rules outlined in WAC 220-610-100, as now or hereafter amended, may serve as guidance for this report. The recommendations in Washington Department of Fish and Wildlife Priority Habitat and Species Management Recommendations found at http://wdfw.wa.gov/conservation/phs/
mgmt_recommendations/ may serve as guidance for habitat management plans created to regulate the design, construction, and operation of projects that affect fish and wildlife conservation areas.

B.    The habitat management plan shall contain a map prepared at an easily readable scale, showing:

1.    The location of the proposed development site;

2.    The relationship of the site to surrounding topography, water features, and cultural features;

3.    Proposed building locations and arrangements; and

4.    A legend which includes a complete legal description, acreage of the parcel, scale, north arrow, and date of map revision.

C.    The habitat management plan shall also contain a report which describes:

1.    The nature and intensity of the proposed development;

2.    An analysis of the effect of the proposed development, activity or land use change upon the wildlife species and habitat identified for protection, including impacts on buffer and building setbacks.

3.    An analysis of any special management recommendations that will be implemented to ensure protection of the species and/or habitat.

4.    A plan which identifies how the applicant proposes to mitigate any adverse impacts to wildlife habitats created by the proposed development. Mitigation measures are required where buffer reduction or intrusions into building setbacks are proposed, and shall include buffer enhancement.

5.    Assessment and evaluation of the effectiveness of the mitigation measures proposed.

6.    Assessment and evaluation of ongoing management practices which will protect fish and wildlife habitat conservation areas after development of the project site, including monitoring and maintenance programs, and operation constraints.

7.    Assessment of project impact or effect on water quality upon SF Dogfish Creek or any regulated stream, and any proposed methods or practices to avoid degradation of water quality.

D.    This plan shall be prepared by a person who has been educated in this field and has professional experience as a fish or wildlife biologist. (Ord. 2017-10 § 2 (Exh. A (part)), 2017: Ord. 2007-24 § 2 (part), 2007. Formerly 16.20.730)

16.20.760 Geotechnical report and geological report.

A.    A geotechnical report shall include a description of the site geology, conclusions and recommendations regarding the effect of geologic conditions of the proposed development, opinions and recommendations of the adequacy of the site to be developed, the effects of groundwater interception and infiltration, seepage, potential slip plans, and changes in soil-bearing strength, and the impacts of the proposed development and appropriate mitigating measures. A geotechnical report may contain information obtained with subsurface investigative measures such as test pit digging, soil boring, water well installation or Dutch Cone Penetrometer investigations. Reports containing engineering 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 thirty percent, must be prepared by, or in conjunction with, a licensed geotechnical engineer as defined below.

1.    Informational Requirements.

a.    A description of the geologic setting of the region, based upon readily available data, including:

i.    Site location and topography;

ii.    Soils and geologic units underlying the site; and

iii.    The location and characteristics of springs within one thousand feet of the site.

b.    A discussion and evaluation of the potential impact of the proposal upon existing geological hazards.

c.    Recommendations on appropriate protection mechanisms, if necessary, to minimize the risk of erosion or landslide.

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 geotechnical engineer as defined in subsection B of this section.

B.    A geotechnical report shall be prepared by a geotechnical engineer (a civil engineer licensed by the state of Washington who is knowledgeable in regional geologic conditions and who has at least four years of 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 of professional experience in site evaluation and development studies, and landslide and/or seismic hazard evaluation.

C.    Report recommendations for siting structures in high risk areas shall be based on existing site conditions rather than measures that have not been successfully approved, designed or constructed (e.g., slope recontouring, slope retaining walls, vegetation improvements, bulkheads, etc.). (Ord. 2017-10 § 2 (Exh. A (part)), 2017: Ord. 2012-10 § 5 (Exh. D) (part), 2012; Ord. 2007-24 § 2 (part), 2007. Formerly 16.20.735)

16.20.765 Hydrogeological report.

A hydrogeological report shall be required for certain proposed operations based on a consultation with the appropriate local and state agencies. The report shall address the impact the proposed land use will have on both the quality and quantity of the water transmitted to the aquifer. The report shall also address the types of pesticides and herbicides and fertilizers that can safely be used for the care of landscaping proposed by the applicant.

A.    The report shall be submitted to the reviewing authority and address, at a minimum, the following criteria:

1.    Surficial soil type and geologic setting;

2.    Location and identification of wells within one thousand feet of the site;

3.    Location and identification of surface water bodies and springs within one thousand feet of the site with recharge potential;

4.    Description of underlying aquifers and aquitards, including water level, gradients and flow direction;

5.    Available surface water and groundwater quality data;

6.    Effects of the proposed development on water quality;

7.    Sampling schedules required to assure water quality;

8.    Discussion of the effects of the proposed development on the groundwater resource;

9.    Recommendations on appropriate BMPs (best management practices) or mitigation to assure no significant degradation of groundwater quality; and

10.    Other information as required by the Bremerton-Kitsap County health district.

B.    The hydrogeological report shall be prepared by a professional geologist/hydrologist or by a soil scientist with a strong background in geology as demonstrated by coursework from an accredited college or university and/or a minimum of five years of experience.

C.    Applications for development or operations with underground storage of petroleum products will be processed using the appropriate procedure as specified in existing city of Poulsbo ordinances.

D.    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 ten feet (or to a depth of 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 two hundred 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 hydrogeological report to determine the presence of highly permeable soils with the recharge area designation.

E.    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 thirty-six or more, and are designated aquifer recharge areas. To facilitate computer analysis, the evaluation may be done on a quarter-quarter 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.
