These design standards are intended to reduce the problems created by improperly designed and installed outdoor lighting. It is intended to reduce problems of glare, minimize light trespass, and help reduce the energy and financial costs of outdoor lighting by establishing regulations which limit the area that certain kinds of outdoor-lighting fixtures can illuminate and by limiting the total allowable illumination of lots located in Hayden.
A. Applicability:
1. All business, residential, and community driveway, sidewalk, and property luminaires should be installed with the idea of being a “good neighbor”, with attempts to keep unnecessary direct light from shining onto abutting properties or streets.
2. Lighting provided for freeways, expressways, limited access roadways, and roads on which pedestrians, cyclists, and parked vehicles are generally not present. The primary purpose of roadway or highway lighting is to help the motorist remain on the roadway and help with the detection of obstacles within and beyond the range of the vehicle’s headlights.
B. Zones Established: The street-lighting system and the City is divided into separate zones to reflect the intensity of illumination required to provide safe travel and protection of property within each zone. These zones shall be as follows:
1. Highway Illumination Zone: The Highway illumination zone shall include all areas requiring illumination along the streets where there is no direct benefit accruing to any particular improved real property owner or occupant. Such zone includes freeway interchanges, the limited access portions of U.S. Highway 95 from Aqua Avenue to Lancaster Road, and other such areas as determined by the City Engineer and/or Public Works Director, where no direct benefit is accrued to any particular improved real property.
2. High Illumination Intensity Zone: The high illumination intensity zone includes areas requiring 20,000 lumen lights to provide for public safety and the safety of the improved real property. The streets in this zone carry the highest traffic volumes. This zone shall include improved real property with frontage on the following streets: Government Way, Hayden Avenue, Prairie Avenue between Wayne Drive and Cornerstone Drive, and other such areas as determined by the City Engineer and/or Public Works Director, where no direct benefit is accrued to any particular improved real property.
3. Moderate Illumination Intensity Zone: The moderate illumination intensity zone includes areas requiring 10,000 lumen lights to provide for the general public safety and the safety of improved real property. The streets in this zone do not have the traffic volume of the high illumination intensity zone, but have greater traffic volumes than residential areas. This zone shall include improved real property with frontage on the following streets: Honeysuckle Avenue between Wayne Drive and Davis Circle, Orchard Avenue between Government Way and Hess Street, Dakota Avenue between Government Way and Highway 95, Lacey Avenue between Government Way an Highway 95, Wyoming Avenue between Government Way and Highway 95, Lancaster Road between Government Way and Warren Street, Ramsey Road between Prairie Avenue and Lancaster Road, and other such areas as determined by the City Engineer and/or Public Works Director, where no direct benefit is accrued to any particular improved real property.
4. Central Business District Illumination Intensity Zone: This illumination intensity zone has been established by the existing luminaires within the district. Any changes to the existing lighting requires approval of the City Engineer and/or Public Works Director.
5. Residential Illumination Intensity Zone: The residential illumination intensity zone includes areas requiring less than 10,000 lumen lights to provide for general public safety and the safety of improved real property. The residential illumination intensity zone includes all improved real property not included in subsections A, B, C and D of this section.
C. Criteria and Standards for Street Lighting: The following streetlight criteria and standards have been applied and shall hereafter apply to provide uniform lighting within each zone sufficient for public safety and the protection of improved real property:
1. In the highway illumination zone, lights shall be placed at all intersections and at all highway overpasses; provided, however, that the placement of such lights shall be determined by the City Engineer in conformance to the policies and purposes expressed in this chapter.
2. In moderate and high illumination intensity zones lights shall be placed at every intersection where practical. Where blocks are longer than 1,800', an additional light shall be placed near the middle of the block.
3. In the residential illumination intensity zone, lights shall be placed at intersections where practical. Where blocks exceed 600' in length, lights shall, where practical, be placed so that no property frontage is a distance of more than 300' from the nearest light.
D. On site, or site specific lighting shall meet the following standards:
1. Parking lot lighting (or building lighting directed into site circulation, pedestrian, or parking areas) shall comply with the following requirements:
a. Lighting shall be energy-efficient and shielded or recessed so that:
(1) The light source (i.e. the bulb) is not visible from off-site;
(2) Glare and reflections are confined to the maximum extent feasible within boundaries of the site.
(3) Each light fixture shall be directed downward and away from adjoining properties and rights-of-way.
(4) A minimum illumination of 0.2 foot-candles per square foot is required.
(5) No lighting shall produce an illumination level greater than 1.0 foot-candles on adjacent residential lots or parcels.
(6) No permanently installed lighting shall blink, flash or be of unusually high intensity or brightness, as determined by the Community Development Director or his/her designee.
(7) Outdoor fixtures shall be limited to a maximum height of 18' or the height of the nearest building, whichever is less.
b. When parking lot lighting is proposed, a photometric plan shall be submitted which demonstrates compliance with these standards.
2. Residential on-site lighting (i.e. accessory building lighting) shall comply with the standards as identified above.
E. Exceptions to the standards above may be granted where the intent of this section is met for the following exterior applications where the lighting is equipped with a control device is independent of the control of the non-exempt lighting. For areas within 300 feet of the airport property boundary, approval of the proposed exception must be approved by the Coeur d’Alene Airport.
1. Specialized signal, directional, and marker lighting associated with transportation.
2. Advertising signage or directional signage.
3. Lighting integral to equipment or instrumentation and installed by its manufacturer.
4 Theatrical purposes, including performance, stage, film production, and video production.
5. Athletic playing areas where lighting is equipped with hoods or louvers for glare control.
6. Temporary lighting.
7. Lighting for industrial production, material handling, transportation sites, and associated storage areas where lighting is equipped with hoods or louvers for glare control.
8. Theme elements in theme and amusement parks.
9. Roadway lighting required by governmental authorities.
10. Lighting used to highlight features of public monuments and registered landmark structures.
11. Lighting for swimming pools and water features.
F. Standards to be considered when reviewing lighting plans, may include but are not limited to the following:
1. Factors to consider when reviewing the temporary/permanent special lighting request:
a. Public and/or private benefits that will result from the temporary lighting;
b. Any annoyance or safety problems that may result from the use of the temporary lighting; and
c. Duration of the temporary nonconforming lighting.
2. Has sustained every reasonable effort to mitigate the effects of light on the environment and the surrounding properties, supported by a signed statement describing the mitigation measures. Such statement shall be accompanied by the calculations required for the Performance Method.
3. All fixtures used for lighting shall be fully shielded as defined in this Code, or be designed or provided with sharp cut-off capability, so as to minimize up-light, spill-light, and glare.
4 All events shall be scheduled so as to complete all activity before or as near to 10:30 p.m. as practical, but under no circumstances shall any illumination of the playing field, court, or track be permitted after 11:00 p.m. except to conclude a scheduled event that was in progress before 11:00 p.m. and circumstances prevented concluding before 11:00 p.m. (Ord. 619, 4-13-2021)
