33.08.050 Airport land use compatibility overlay.
The airport land use compatibility overlay and related overlay zone classifications are designated on Map 33.08.020 (1a). Overlay designations and classifications are based on many factors including, but not limited to: extent of airport ownership and operations; aircraft traffic patterns; National Transportation Safety Board aircraft accident data; state airport land use compatibility guidelines; airport and surrounding land uses; existing limitations and easements to protect the airport from incompatible adjacent land uses; and State, federal, and local policies, guidelines, and regulations. All aviation-related allowed land uses must be consistent with applicable Federal Aviation Administration (FAA) regulations.
(1) Runway Protection (Zone 1). The runway protection zone contains the airport runway, areas immediately adjacent to the runway, and areas where low altitude aircraft traffic patterns occur near the ends of the runway. The purpose of this zone is to maintain areas that are generally free of structures and other obstructions, and avoid uses that allow human occupation or significant concentrations of people for any significant period of time. Compatible land uses include those aviation uses directly related to the operation of the airport and non-aviation uses such as crops, pasture, and other open lands.
(a) Land Use. Allowed land uses are limited to the following:
(i) Agriculture (no structures or livestock);
(ii) Aircraft runways and taxiways;
(iii) Aviation navigational aids;
(iv) Structures required for airport operation (no human occupation);
(v) Open lands.
(b) Protection Standards.
(i) All other aviation and nonaviation uses not listed as allowed are prohibited.
(ii) Existing residential development rights allowed by the underlying zoning district may be transferred to contiguous areas that are part of a residential land division.
(2) Airport Hangar Development (Zone 2). The purpose of this zone is to allow opportunities for limited aviation land uses on airport associated properties that are consistent with the character of existing airport uses and that minimize impacts to adjacent lands outside the overlay district.
(a) Land Use. Allowed land uses are limited to the following:
(i) Agriculture (no livestock);
(ii) Aircraft hangars (24,000 square feet or less);
(iii) Aircraft maintenance and service;
(iv) Aircraft taxiways;
(v) Aviation navigational aids;
(vi) Structure required for airport operation (no human occupation);
(vii) Open lands.
(b) Protection Standards.
(i) All other aviation and nonaviation uses not listed as allowed are prohibited.
(ii) Existing residential development rights allowed by the underlying zoning district may be transferred to contiguous areas that are part of a residential land division.
(iii) Tiedowns must be set back 200 feet from the centerline of the runway.
(iv) All structures must be set back 275 feet from the centerline of the runway.
(v) A minimum of 30 percent of the parcel must remain free of structures and impervious surfaces (e.g., parking lots).
(vi) New aviation development must provide for a visual screen along all property lines that border areas located outside of the Airport Land Use Compatibility Overlay consistent with the landscaping requirements in Chapter 33.53 CCC.
(vii) No land use, building, or structure shall be permitted that promotes above ground storage of bulk fuel, flammable substances, or materials with a tank size greater than 6,000 gallons.
(viii) All aircraft hangars and other facilities must be separated from other structures by a minimum of 75 feet subject to any additional separation requirements to satisfy building requirements or FAA design standards.
(3) Airport Development (Zone 3). The purpose of this zone is to allow for aviation-related land uses and limited, nonaviation uses that are compatible with airport operations and character on airport property. Lands within this zone are already characterized by airport development such as aircraft maintenance and servicing, aircraft hangers, fueling facilities, taxiways, and aircraft tiedown areas.
(a) Land Use. Allowed land uses are limited to the following:
(i) Agriculture;
(ii) Aircraft or aviation related business (10,000 square feet or less);
(iii) Aircraft fueling facilities;
(iv) Aircraft hangars (24,000 square feet or less);
(v) Aircraft maintenance and service;
(vi) Aircraft taxiways;
(vii) Aircraft tiedowns;
(viii) Airport towers and terminals;
(ix) Aviation navigational aids;
(x) Storage facility (10,000 square feet or less);
(xi) Other aviation operation uses (no human occupation);
(xii) Open lands;
(xiii) Public buildings (10,000 square feet or less).
(b) Protection Standards.
(i) All other aviation and nonaviation uses not listed as allowed are prohibited.
(ii) Existing residential development rights allowed by the underlying zoning district may be transferred to contiguous areas that are part of a residential land division.
(iii) Commercial storage must be fully contained within buildings.
(iv) New development must provide for a visual screen along all property lines that border areas located outside of the Airport Land Use Compatibility Overlay consistent with the landscaping requirements in Chapter 33.53 CCC.
(v) A minimum of 30 percent of the parcel must remain free of structures and impervious surfaces (e.g., parking lots).
(vi) New structures must be located a minimum of 50 feet from all property lines that border areas located outside of the Airport Protection Zone Overlay.
(vii) All aircraft hangars and other facilities must be separated from other structures by a minimum of 75 feet subject to any additional separation requirements to satisfy building requirements or FAA design standards.
(4) Aviation Related Residential (Zone 4). The purpose of this zone is to allow opportunities for aviation-related single-family residential development compatible with airport operations and consistent with the standards of the underlying agriculture retention zone on property connected with the airport.
(a) Land Use. Allowed land uses are limited to the following:
(i) Agriculture;
(ii) Aircraft hangars (Less than 4,000 square feet);
(iii) Aircraft taxiways;
(iv) Aviation navigational aids;
(v) Open lands;
(vi) Single-family dwelling and accessory uses.
(b) Protection Standards.
(i) Residential development subject to the standards of the underlying zoning district.
(ii) No land use, building, or structure shall be permitted that promotes above ground storage of bulk fuel, flammable substances, or materials with a tank size greater than 6,000 gallons.
(5) Extended Runway Centerline Protection (Zone 5). The purpose of this zone is to promote compatible land uses in areas in close proximity to aircraft landing and take-off patterns, and to retain open lands along the extended runway centerline in case of need for emergency landing.
(a) Land use. Subject to the standards of the underlying zoning district.
(b) Protection standards.
(i) Asphalt plants are prohibited.
(ii) Schools, child daycare centers, family childcare homes, hospitals, convalescent and nursing homes, or other uses where the mobility of occupants is compromised are prohibited.
(iii) Conditional use permit is required for any allowed uses within the zoning district that allow public use and access.
(iv) No land use, building, or structure shall be permitted that promotes above ground storage of bulk fuel, flammable substances, or materials with a tank size greater than 6,000 gallons.
(c) Sequim Valley Airport Specific Protection Standards. New structures must be set back a minimum of 75 feet from the extended runway centerline in Zone 5 areas west of Sequim Valley Airport. This requirement does not apply to Zone 5 areas located within the Carlsborg urban growth area (UGA) where the extended runway centerline and adjoining areas are already significantly developed.
(6) Airport Influence Area (Zone 6). The Airport Influence Area (Map 33.08.020 (1a)) covers Airport Land Use Compatibility Overlay Zones 1 through 6 and approximates the area subject to the regular or potential traffic pattern of the airport. The purpose of this zone is to inform current, future, and prospective residents, businesses, and landowners of potential increased noise levels, vibration, fumes, smell, low-flying aircraft, and other aviation related disturbances, and to avoid uses that may create potential hazards to aircraft in flight.
(a) Land Use. Subject to the standards of the underlying zoning district.
(b) Protection Standards.
(i) No land use shall be made of any land within the Airport Influence Area that will cause electrical interference with navigational signals or radio communications at the airport or with radio or electronic communications between the airport and aircraft. Said interference will be regulated in accordance with and enforced by the Federal Communication Commission (FCC) and the FAA.
(ii) No land use, building, or structure shall emit emissions of fly ash, dust, vapor, gases or other forms of emissions within the Airport Influence Area that may conflict with any current and planned operations of the airport.
(iii) No land use requiring a Clallam County building or land use permit or approval shall be permitted that would foster an increase in the bird population within the Airport Influence Area and thereby increase the likelihood of causing a bird-aircraft impact, including, but not limited to, solid waste landfills, sewage lagoons, or creation of standing areas of water greater than one-half acre.
(iv) No structure, device or other object located within Airport Influence Area shall be placed or erected that makes it difficult for pilots to distinguish between airport lights and other lights, results in glare in the eyes of pilots using the airports, impairs visibility in the vicinity of the airport, or otherwise endangers the landing, taking off, or maneuvering of aircraft. This includes but is not limited to reflective roofing, siding material, and standing areas of water greater than one-half acre.
