20.25.005 Description and purpose.

The intent of these regulations is to avoid impacts to streams, riparian habitat, anadromous fish, and wildlife conservation areas where such avoidance is feasible and reasonable. This chapter contains standards, guidelines, criteria and requirements intended to identify, evaluate and mitigate potential impacts to habitat conservation areas within the city and to enhance degraded habitat and streams in appropriate cases. In appropriate circumstances, impacts resulting from regulated activities may be minimized, rectified, reduced and/or compensated for, consistent with this chapter. (Ord. 1801 § 22, 2018).

20.25.010 Classification and designation of fish and wildlife habitat conservation areas.

While not all the following critical fish and wildlife habitat conservation areas are known to exist in the city, their designation here allows for future categorization for protection. The following categories shall be used for relevant development standards:

(1) Areas with which state or federally designated endangered, threatened, and sensitive species have a primary association.

(a) Federally designated endangered and threatened species are those fish and wildlife species identified by the U.S. Fish and Wildlife Service (USFWS) and the National Marine Fisheries Service (NMFS) that are in danger of extinction or threatened to become endangered. The USFWS and NMFS should be consulted for current listing status.

(b) State designated endangered, threatened, and sensitive species are those fish and wildlife species native to the state of Washington identified by the Washington Department of Fish and Wildlife (WDFW), that are in danger of extinction, threatened to become endangered, vulnerable, or declining and are likely to become endangered or threatened in a significant portion of their range within the state without cooperative management or removal of threats. State designated endangered, threatened, and sensitive species are periodically recorded in WAC 232-12-014 (state endangered species) and WAC 232-12-011 (state threatened and sensitive species). The WDFW maintains the most current listing and should be consulted for current listing status.

(c) State priority habitats and areas associated with state priority species are considered to be priorities for conservation and management. Priority species require protective measures for their perpetuation due to their population status, sensitivity to habitat alteration, and/or recreational, commercial, or tribal importance. Priority habitats are those habitat types or elements with unique or significant value to a diverse assemblage of species. A priority habitat may consist of a unique vegetation type or dominant plant species, a described successional stage, or a specific structural element. Priority habitats and species (PHS) are identified and listed by the WDFW;

(2) Areas of rare plant species or high-quality ecosystems identified by the Washington State Department of Natural Resources (WDNR) through the Natural Heritage Program under Chapter 79.70 RCW;

(3) State Natural Area Preserves and Natural Resource Conservation Areas. Natural area preserves and natural resource conservation areas are defined, established, and managed by the WDNR;

(4) Habitats and species of local importance, as identified by the city in accordance with OHMC 20.25.020;

(5) Commercial and recreational shellfish areas, including all public and private tidelands or bedlands suitable for shellfish harvest as well as shellfish protection districts established pursuant to Chapter 90.72 RCW;

(6) Geoduck concentration areas, including all public and private bedlands suitable for geoduck colonization;

(7) Kelp and eelgrass beds; herring, smelt, and other forage fish spawning areas;

(8) Naturally occurring ponds under 20 acres and their submerged aquatic beds that provide fish or wildlife habitat, including those artificial ponds intentionally created from upland areas for mitigation purposes;

(9) Waters of the state as defined in RCW 90.48.020 and include lakes, rivers, ponds, streams, inland waters, underground waters, salt waters, and all other surface waters and water courses in Washington.

(a) Stream types are established by the WDNR and classified in WAC 222-16-030 and include:

(i) Type S water means all waters, within their bankfull width, as inventoried as “shorelines of the state” under Chapter 90.58 RCW and the rules promulgated pursuant to Chapter 90.58 RCW including periodically inundated areas of their associated wetlands.

(ii) Type F water means segments of natural waters other than Type S waters, which are within the bankfull width of defined channels and periodically inundated areas of their associated wetlands, or within lakes, ponds, or impoundments having a surface area of one-half acre or greater at seasonal low water and which in any case contain fish habitat.

(iii) Type Np water means all segments of natural waters within the bankfull width of defined channels that are perennial nonfish habitat streams. Perennial streams are waters that do not go dry any time of a year of normal rainfall.

(iv) Type Ns water means all segments of natural waters within the bankfull width of the defined channels that are not Type S, F, or Np waters. These are seasonal, nonfish habitat streams in which surface flow is not present for at least some portion of a year of normal rainfall and are not located downstream from any stream reach that is a Type Np water. Type Ns waters must be physically connected by an above-ground channel system to Type S, F, or Np waters. (Ord. 1801 § 23, 2018; Ord. 1440 § 4, 2005).

20.25.020 Designation of habitats and species of local importance.

(1) Habitats and species of local importance are those identified for protection by the city. Habitats may include a seasonal range or habitat element with which a species has a primary association, and which, if altered, may reduce the likelihood that the species will maintain and reproduce over the long term.

(2) The city shall accept and consider nominations for habitat areas and species to be designated as locally important on an annual basis. Habitats and species may be nominated for designation by any person.

(3) Habitats and species to be designated shall exhibit at least one of the criteria in subsections (3)(a) through (3)(c) of this section and shall meet the criteria in subsections (3)(d) through (3)(f) of this section.

(a) Local populations of native species are vulnerable or declining or are likely to become threatened or endangered based on existing or predictable threats;

(b) The species or habitat has recreational, commercial, game, tribal, or other special value;

(c) Long-term persistence of a species within the urban growth area of Oak Harbor is dependent on the protection, maintenance and/or restoration of the nominated habitat;

(d) Protection by county, state, or federal policies, laws, regulations, or nonregulatory tools is not adequate to prevent degradation of the species or habitat in the city; and

(e) Without protection, there is likelihood that the species or habitat will decline over the long term.

(f) Nominated areas must represent high-quality native habitat or habitat that either has a high potential to recover to a suitable condition and is of limited availability or provides landscape connectivity contributing to conservation of the designated species or habitat.

(4) A petition to nominate an area or a species to this category shall contain all of the following, using best available science:

(a) A statement demonstrating that nomination criteria are met;

(b) A proposal for whether specific habitat features should be protected (for example, nest sites, breeding areas, and nurseries), or whether the habitat or ecosystem is being nominated in its entirety;

(c) Proposed management strategies for the species or habitats. Where restoration of habitat is proposed, a conceptual plan for restoration must be provided as part of the nomination;

(d) Signatures of all petitioners.

(5) The director shall determine whether the nomination proposal is complete, and if complete, shall evaluate it according to the characteristics enumerated in subsection (3) of this section and make a recommendation to the planning commission based on those findings.

(6) The planning commission shall hold a public hearing for proposals found to be complete and make a recommendation to the city council based on the characteristics enumerated in subsection (3) of this section.

(7) Following the recommendation of the planning commission, the city council shall hold an additional public hearing and shall determine by ordinance whether the designation criteria in this section have been met. Designation of a habitat or species of local importance shall be by ordinance.

(8) Approved nominations shall be specified in OHMC 20.25.010 and shall be subject to the provisions of the critical areas regulations in this title. (Ord. 1440 § 4, 2005).

(11) WDFW “Land Use Planning For Salmon, Steelhead and Trout: A Land Use Planner’s Guide to Salmonid Habitat Protection and Recovery.” (Ord. 1801 § 24, 2018; Ord. 1440 § 4, 2005).

20.25.040 Riparian buffers.

(1) Standard Buffer Widths. Aquatic fish and wildlife habitat conservation areas shall be protected with vegetated buffers, which also provide riparian wildlife habitat. These buffers shall have the following standard widths, measured perpendicular from the ordinary high water mark of the water body:

(a) Type F streams: 100 feet throughout all reaches used by salmonids at any life stage at any time of the year, including reaches likely to be used by salmonids after foreseeable downstream restoration, as determined by the director;

(b) Type Np and Ns streams: 50 feet;

(c) Type S (including marine shorelines identified as fish and wildlife habitat conservation areas): 100 feet.

(2) Reductions for Lower Impact Land Uses. Buffer widths in subsection (1) of this section assume high-intensity land use is occurring adjacent to the water body, as is characteristic of an urban area. These widths may be reduced up to 25 percent if measures to minimize the impacts of the land use adjacent to the water body are applied, such as use of low impact development techniques, if feasible, retention of as much native vegetation and soils as possible, direction of noise and light away from the water body, and other measures that may be suggested by a qualified professional. Buffer widths may also be reduced up to 25 percent for lower impact land uses such as agriculture, at the discretion of the director and if best management practices are applied. If proposed future land uses are more intense, they are not eligible to maintain this reduction.

(3) Reductions for Restoration. Buffer widths may be reduced up to an additional 25 percent if the buffer is restored or enhanced from a preproject condition that is disturbed (e.g., dominated by invasive species), so that functions of the postproject buffer are equal or greater. The restoration plan must meet requirements in OHMC 20.12.100 for a mitigation plan and OHMC 20.25.050 for a critical areas report. This reduction may be added to reductions for lower impact land uses.

(4) Buffer Averaging. The director shall have the authority to average buffer widths on a case-by-case basis, where a qualified professional demonstrates to the director’s satisfaction that all of the following criteria are met:

(a) The total area contained in the buffer after averaging is no less than that contained within the buffer prior to averaging;

(b) Decreases in width are generally located where riparian functions may be less sensitive to adjacent land uses, and increases are generally located where riparian functions may be more sensitive to adjacent land uses, to achieve no net loss or a net gain in functions;

(c) The averaged buffer, at its narrowest point, shall never be less than 25 feet;

(d) The buffer has not been reduced in accordance with this section. Buffer averaging is not allowed if the buffer has been reduced; and

(e) There were no feasible alternatives to the site design without buffer averaging.

(5) Signage. Signs shall identify postproject riparian buffers as critical areas or native growth protection areas, in accordance with OHMC 20.12.140(2).

(6) Allowed Uses. The following uses may be permitted within a riparian buffer, provided they are not prohibited by any other applicable law and they are conducted in a manner so as to minimize negative impacts to the buffer and adjacent water body:

(a) Conservation or restoration activities aimed at protecting the soil, water, vegetation, or wildlife and designed consistent with the WDFW “Stream Habitat Restoration Guidelines” (2012).

(b) Passive recreation facilities consistent with an approved critical areas report, including:

(i) Wildlife-viewing structures; and

(ii) Walkways and trails, provided pathways minimize adverse impacts on water quality. They should generally be parallel to the perimeter of the water body, located in the outer 25 percent of the riparian buffer area, and avoid removal of significant trees. They should be limited to pervious surfaces no more than five feet in width.

(c) Stream crossings, if necessary to provide access to property and if impacts are fully mitigated consistent with an approved critical areas report and the Washington State Department of Fish and Wildlife “Water Crossing Design Guidelines” (2013).

(d) Storm water management facilities, limited to approved low impact development techniques, may be allowed within the outer 25 percent of riparian buffers; provided, that:

(i) No other location with less impact is feasible; and

(ii) Mitigation for impacts is provided to achieve no net loss or a net gain in functions.

(e) Marine Shoreline Erosion Control Measures. New, replacement, or substantially improved marine shoreline erosion control measures may be permitted, consistent with all necessary state and federal permits and in accordance with an approved critical areas report that demonstrates the following:

(i) No feasible alternative would provide adequate protection to upland property;

(ii) Bioengineering or soft armoring shall be employed to the greatest extent feasible;

(iii) Mitigation measures shall ensure there is no net loss of the functions or values of intertidal or riparian habitat, allowing for off-site mitigation if necessary.

(f) Accepted erosion control measures may be found in the WDFW “Marine Shoreline Design Guidelines” (2014).

(g) Streambank Stabilization. Streambank stabilization to protect structures from future channel migration is not permitted except when achieved through bioengineering or soft armoring techniques in accordance with an approved critical areas report and all necessary state and federal permits.

(h) Streambank stabilization techniques may be found in the WDFW “Integrated Streambank Protection Guidelines” (2002).

(i) Public Flood Protection Measures. New public flood protection measures and expansion of existing ones may be permitted, subject to the director’s review and approval of a critical areas report and all necessary state and federal permits. (Ord. 1801 §§ 25 – 28, 2018; Ord. 1440 § 4, 2005).
