Ordinance 3312-13 - Laserfiche WebLink

a. Lighting and Glare Site Lighting. The intent of this provision is to encourage the use of lighting as an integral design component to enhance buildings, landscaping, or other site features; increase night sky visibility and to reduce the general illumination of the sky; reduce horizontal light glare and vertical light trespass from a development onto adjacent parcels and natural features; use lighting in conjunction with other security methods to increase site safety. 1. All site lighting shall meet dark-sky standards. 2. Site lighting levels. All publicly accessible areas shall be lighted with average minimum and maximum levels as follows: a. Minimum of 0.5 foot candles; b. Maximum (for high volume pedestrian areas and building entries) of 4 foot candles. 3. Lighting shall be provided at consistent levels, with gradual transitions between maximum and minimum levels of lighting and between lit areas and unlit areas. Highly contrasting pools of light and dark areas shall be avoided. 4. Parking area lighting fixtures shall be full cut-off(0% candlepower at 90° horizontal and 10% maximum candlepower at 80° from vertical), dark sky rated, and mounted no more than 30 feet above the ground, with lower fixtures preferable so as to maintain a human scale. 5. Lighting for parking areas within 300' of areas designated for residential uses shall be on light standards not exceeding 20' or the height of any building situated between the parking area and the area designated for residential use, whichever is taller. 6. Pedestrian-scaled lighting (light fixtures no taller than 15 feet) is encouraged in areas of pedestrian activity 7. Lighting must not trespass onto adjacent private parcels, nor shall a light source (luminaire) be visible at the property line. All building lights shall be directed onto the building itself and/or the ground immediately adjacent to it. The light emissions shall not be visible above the roofline of the building. 8. Building wall mounted parking lot lighting is prohibited. A lighting plan demonstrating compliance with these standards shall be submitted for review and approval at time of submittal for any permit that includes site lighting. b. Noise i. Noise of machines and operations shall be muffled so as to not become objectionable due to intermittence or beat frequency, or shrillness. ii. Any use that would potentially generate significant noise shall submit a study by an independent acoustical engineer during the applicable review process. The study must describe mitigation measures necessary to ensure the development will comply with the City's noise regulations, such as site design, types of facilities and equipment, and facilities operations. 30
