5-8(F)   LIGHTING DESIGNATION FOR ZONE DISTRICTS

Table 5-8-2: Lighting Designations by Zone District specifies 129 the equivalent llowed in each zone district based on allowable land uses. Where multiple designations are specified for a zone district, the notes in the table identify which designation shall be used depending on context.

5-8(F)(1)   Planned Development Zone Districts

5-8(F)(1)(a)   Existing PD or PC zone districts that did not establish lighting standards must come into compliance with the requirements of the lighting designation that most closely matches their current land use and surrounding contexts as established in Table 5-8-2 pursuant to Subsection 14-16-6-8(G).

5-8(F)(1)(b)   Any new PD or PC zone districts shall establish the lighting designation(s) that most closely matches the allowable uses of the zone districts in Table 5-8-2 and the lumen limits from Subsection 14-16-5-8(F) in the Site Plan - EPC, pursuant to Subsection 14-16-6-6(I), or Framework Plan, pursuant to Subsection 14-16-6-7(H), as relevant, with an outdoor and site lighting performance analysis pursuant to Subsection 14-16-6-4(H)(3).

5-8(F)(2)   Non-residential Sensitive Use (NR-SU) Zone District

5-8(F)(2)(a)   Existing NR-SU zone districts that did not previously establish lighting standards must come into compliance with the requirements of the lighting designation that most closely matches their current land use and surrounding context as established in Table 5-8-2 pursuant to Subsection 14-16-6-8(G).

5-8(F)(2)(b)   Any new NR-SU zone district shall establish the lighting designation(s) that most closely matches the allowable uses of a zone district in Table 5-8-2 and the lumen limits from Subsection 14-16-5-8(F) in their Site Plan - EPC pursuant to Subsection 14-16-6-6(I) with an outdoor and site lighting performance analysis pursuant to Subsection 14-16-6-4(H)(3).

5-8(F)(3)   Non-residential Parks and Open Space (NR-PO)

5-8(F)(3)(a)   City Parks & Recreation staff shall identify environmentally sensitive areas that need protection from anthropogenic light and design outdoor and site lighting based on the lowest possible lighting designation in Table 5-8-2. Pedestrian walkways and bicycle paths in parking areas shall be lit with pedestrian-scale lighting.

5-8(F)(3)(b)   City Parks & Recreation staff shall identify adjacent properties and design outdoor and site lighting based on the appropriate lighting designation in Table 5-8-2.

5-8(F)(4)   Light Trespass

5-8(F)(4)(a)   Unless specified elsewhere in this IDO, all outdoor luminaires shall be located or optically shielded such that the point light source is not visible from adjacent property or public right-of-way.

5-8(F)(4)(b)   The total illumination from outdoor light sources and interior light escaping from windows shall not exceed light trespass limits in Table 5-8-3, as measured at any location along the property line in both of the following ways:

   1.   Horizontally at finished grade with the light meter facing upward.

   2.   Vertically at 5 feet (1.5 meters) above finished grade with the light meter aiming toward the subject property.

 

TABLE 5-8-3: LIGHT TRESPASS LIMITS BY LIGHTING DESIGNATION
	NDZ	Lz0	Lz1	Lz2	Lz3
Foot Candles (fc)	0.02	0.05	0.1	0.3	0.8
Lux (lx)	0.2	0.5	1.0	3.0	8
Luminance (cd/m2)	0	1	20	40	80

 

5-8(F)(4)(c)   If the total illumination from outdoor light sources and interior light escaping from windows exceeds light trespass limits in Table 5-8-3 at any point along the property line, lighting must be re-aimed, removed, turned off, or dimmed until compliance is reached. 130

5-8(G)   TOTAL LUMEN ALLOWANCE

All sources of light visible from the exterior of a property shall meet the requirements of this Subsection 14-16-5-8. Only 20 percent of the total allowable site lumens in Table 5-8-4 or Table 5-8-5 is allowed to be uplight (i.e. light emitted above 90 degrees from nadir).

5-8(G)(1)   Residential Uses

5-8(G)(1)(a)   Total Lumen Allowance

Table 5-8-4 specifies 131 the total exterior lumens allowed for each dwelling on a subject property.
