Summary

Freeland outdoor lighting cannot exceed 1.0 footcandle at the property line, dropping to 0.5 footcandle where the neighboring lot is zoned Low or Medium Density, under Island County Code Section 17.06.570.D.3. Any spillover onto Low or Medium Density neighbors must also be minimized with shielding, frosted bulbs, or landscaping under Section 17.06.570.E.5.

These county ordinances apply to unincorporated areas of Island County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

3.Maximum light levels.(i)Lighting must be oriented to the interior of the property and not onto adjacent properties, streets or sidewalks.(ii)The average illumination level shall not exceed 1.5 footcandles for the illuminated non-residential areas and .55 footcandles for residential areas.(iii)The maximum light level of any light fixture cannot exceed 1.0 footcandles measured at the property line.(iv)Where adjacent to Low Density or Medium Density zoning districts, the maximum light level of any light fixture cannot exceed 0.5 footcandles measured at that property line.(v)The maximum light level shall not exceed 0.2 footcandles as a direct result of the on-site lighting measured five (5) feet beyond the property line. ... 5.Light trespass and glare onto neighboring Low Density or Medium Density zoned properties shall be minimized through shielding of the light fixtures, use of frosted bulbs, peripheral landscaping or fencing, building placement, or another effective method or combination of methods.

Full Breakdown

D governs how light levels are measured, in footcandles at ground level with the meter held parallel to the ground and pointing up. 2 footcandle measured five feet beyond the property line. 5 requires trespass and glare onto neighboring Low or Medium Density property to be minimized through shielding, frosted bulbs, peripheral landscaping or fencing, or building placement, with year-round screening required regardless of winter dieback. 7.

Violations & Fines

A lighting plan showing photometric footcandle levels on a 10-foot grid must be submitted with site plan, conditional use, or common-area subdivision applications (17.06.570.J), and the Planning Director can require a lighting professional's certification that a design meets these trespass limits before approving it. General code-enforcement, complaint, and penalty procedures under Island County Code Titles 16 and 17 (17.06.030.A) apply once a property is found exceeding the footcandle caps.

Frequently Asked Questions

How bright can my outdoor light be at my property line in Freeland?
Section 17.06.570.D.3(iii) caps any single fixture at 1.0 footcandle measured at the property line. If your neighbor's lot is zoned Low or Medium Density, subsection (iv) lowers that cap to 0.5 footcandle at that boundary, and subsection (v) adds an overall limit of 0.2 footcandle five feet past the line from all fixtures combined.
What can I do if a neighbor's business lighting shines onto my Freeland home?
Section 17.06.570.E.5 requires light trespass and glare onto neighboring Low or Medium Density zoned property to be minimized through fixture shielding, frosted bulbs, landscaping or fencing, or building placement, and the county's general code-enforcement complaint process under Section 17.06.030.A can be used to raise a violation of the footcandle caps.
Can a trail through a wetland buffer be lit at night in Freeland?
Not for general illumination. Section 17.06.570.E.6 prohibits lighting critical areas and their buffers, and allows only limited pathway safety lighting for trails through them, and even that is subject to the security-lighting standards in Section 17.06.570.H.7.
