17.70.010 Title.

This chapter shall be called “General Development Standards.” (Ord. 1933 § 1 (Exh. A), 2023; Ord. 1857 § 2 (Exh. B), 2018).

17.70.020 Application.

This chapter shall apply to the use and development of land, the construction of new buildings, and to the expansion or modification of existing uses, structures and developments. (Ord. 1933 § 1 (Exh. A), 2023; Ord. 1857 § 2 (Exh. B), 2018).

17.70.030 Purpose.

The purpose of supplemental development standards is to achieve compatible land uses within zoning districts and surrounding areas by providing uniform regulations throughout each district, encouraging neighborhood stability and consistency, and promoting commercial viability and compatibility. (Ord. 1933 § 1 (Exh. A), 2023; Ord. 1857 § 2 (Exh. B), 2018).

17.70.040 Authority.

This chapter is adopted pursuant to the provisions of chapters 35.63, 35A.63, 36.70A, and 36.70B RCW and other applicable laws and regulations. (Ord. 1933 § 1 (Exh. A), 2023; Ord. 1857 § 2 (Exh. B), 2018).

17.70.045 Prohibited uses.

The following uses and developments shall be prohibited in all zones and throughout the city of Burlington. This list is not exhaustive and is only intended to highlight specific uses which are explicitly prohibited in all other zones. Other uses may also be prohibited pursuant to BMC 17.05.090(E) and other applicable code provisions.

A. Agriculture, rural;

B. Shooting range, outdoors;

C. Billboards and off-site advertising;

D. Electric fences;

E. Commercial composting;

F. Bulk storage, manufacturing, processing, handling, or disposal of hazardous substances such as chemicals, petroleum products, medical waste, radioactive material, and explosives. This prohibition shall not apply to minor quantities incidental to a permitted use or activity. (Ord. 1933 § 1 (Exh. A), 2023).

17.70.050 Performance standards.

The purpose of this section is to establish the following performance standards which are intended to reduce the visual, physical, and environmental impacts of new development on existing uses and developments.

A. Light and Glare. Building materials with high light-reflective qualities shall not be used in the construction of buildings in such manner that reflected sunlight will throw intense glare to surrounding areas. Artificial lighting shall be hooded or shaded so that direct light of high-intensity lamps will not result in glare when viewed from residential areas surrounding a commercial or industrial district.

B. Electrical Interference. Provision must be made for necessary shielding or other preventive measures against interference occasioned by mechanical, electrical and nuclear equipment uses or processes with electrical apparatus in nearby buildings or land uses.

C. Odorous Gases and Matter. The emission of odorous gases or matter in such quantities as to be readily detectable, without special instruments, at any point beyond the property line of the use creating the odor, is prohibited.

D. Smoke and Particulate Matter Emissions. No emissions shall exceed the allowances set forth by the Environmental Protection Agency, the Washington State Department of Ecology and/or the Northwest Sound Air Pollution Control Agency, unless local regulations are more restrictive, in which case the local regulation shall apply.

E. Dust, Dirt, Fly Ash, or Airborne Solids. No observable dust, dirt, fly ash or other airborne solids shall be emitted except as related to construction activity.

F. Waste Storage. Storage of animal or vegetable wastes which attract insects or rodents or otherwise create a health hazard shall be prohibited. No waste products shall be exposed to view, from eye level, beyond the property line of the use storing the waste.

G. Toxic Gases and Matter. No emissions of toxic gases or matter shall be permitted.

H. Vibration. Vibration which is easily discernible, without special instruments at any point beyond the property line, is prohibited. This shall not apply to vibration caused by highway vehicles, trains, aircraft or construction activities.

I. Hazardous Substance and Waste. No hazardous substances or wastes shall be released into the environment so as to cause dangerous or offensive emission or contamination of any public or private water supply, sewage treatment processes, watercourse or water body, the air, or the ground, except in accordance with standards approved by provisions of federal, state and local laws and regulations, and the International Fire Code. (Ord. 1933 § 1 (Exh. A), 2023; Ord. 1857 § 2 (Exh. B), 2018).
