9.6 PROHIBITED EMISSIONS FROM ANY PROPERTY

To promote compatibility between adjacent properties, the following types of emissions will be considered zoning violations and are prohibited. Enforcement of these prohibitions Gilpin County Zoning Regulations 63 will be as any zoning violation pursuant to 30-28-124 CRS, and shall be in addition to other remedies.

9.6.1 Exterior Light. Exterior lighting, except for overhead public street lighting and warning, emergency or traffic signals, shall be installed in such a manner that the light source will be sufficiently obscured to prevent glare on public streets and walkways or into any residential area. The installation or erection of any lighting that may be confused with warning signals, emergency signals or traffic signals is prohibited.

9.6.1.2 Private Commercial

9.6.1.2.1 Maximum total outdoor light output shall not exceed 10,000 lumens per 1000 square feet of ground floor commercial space to a maximum of 75,000 lumens.

9.6.1.2.2 Under canopy lighting shall not exceed 15 lumens per square foot. Total output from such uses shall be applied toward the above total lumen cap at a 50% rate.

9.6.1.2.3 Parking lot and circulation road lighting shall not exceed 2 lumens per square foot. Total output from such lighting shall be applied toward the above total lumen cap at a 100% rate

9.6.1.2.4 Indoor lighting shall count toward the above total allowable lumen cap at a ratio directly related to the area of front window glass as a proportion of the total area of the front elevation. That ratio shall be as follows: .25 x Total Visible Indoor Lumens x (window area / front elevation area)

9.6.1.2.5 All commercial outdoor light sources shall be fully shielded. Shields shall extend below the horizontal plane running through the lowest point of the light source a distance of 1 inch for Gilpin County Zoning Regulations 64 every 1 foot of height. Shielding shall direct light downward a minimum of 45 degrees from the horizontal.

9.6.1.3 Exceptions to Sections 1 and 2 above shall be limited to:

9.6.1.3.1 Security lights activated by motion detectors under the following conditions:

• Illumination cycle shall be less than 5 minutes.
• Activation shall be triggered only by motion originating from within the bounds of the lot on which the light is installed.
• Maximum upward angle a concentrated light source ( e.g. flood light) may be directed is 45 degrees from straight down.

The light source shall not be directly visible to motor vehicle operators on adjacent public roads.

9.6.1.3.2 Low output lights (less than 100 lumens per source) used for decorative purposes for a maximum 30 days per calendar year.

9.6.1.3.3 By Special Use Permit only, lights used to illuminate outdoor recreation facilities owned or operated by Gilpin County or other government entities. All such lights must be fully shielded so that no light is directed beyond the field of play.

9.6.1.3.4 Public. Overhead public street lighting shall be so shielded that the light element is not visible from outside the dedicated right of way. Illumination at street level directly under a light shall not exceed 1fc.

9.6.1.3.5 Amortization: Non conforming commercial lights, and impinging residential lights in existence before January 14, 2003 must come into compliance on or before January 13, 2008, being five year after the adoption of revised Section 9.6.A.1 inclusive.
