5-8(E)   GENERAL DESIGN AND ILLUMINATION STANDARDS

All sources of light visible from the exterior of a property subject to this Section 14-16-5-8 shall meet the following standards.

5-8(E)(1)   Uplight Restrictions

5-8(E)(1)(a)   Unless specified otherwise in this IDO, luminaires shall be fully shielded or have a U0 rating (i.e. a luminaire that emits zero lumens above 90 degrees from nadir). Unshielded floodlights with articulated mounting are prohibited.

5-8(E)(1)(b)   Luminaires installed under canopies, porte cocheres, or beneath similar structures shall meet all of the following requirements.

   1.   Luminaires shall be mounted to aim downward and installed flush-mounted or recessed above the lowest edge of the canopy such that the lowest part of the luminaire is shielded from view beyond the property line.

   2.   The vertical fascia shall not be internally illuminated.

   3.   All light emitted shall be substantially confined to the posts, facades, and ground surface directly beneath the perimeter of the canopy or similar structure.

5-8(E)(2)   Correlated Color Temperature (CCT) and Color Rendering Index (CRI) 127

5-8(E)(2)(a)   Unless specified elsewhere in this IDO, outdoor lighting shall have a maximum CCT of 3000K. The minimum CRI for these light sources shall be 65.

5-8(E)(2)(b)   Light sources below 2700K with limited spectral emission and (CRI) values below 65, such as low-pressure sodium or amber LED, are allowed within NDZ or Lz0 lighting designations, pursuant to Subsection 14-16-5-8(E)

5-8(E)(3)   Light Poles

Table 5-8-1 specifies 128 the maximum height of light poles, measured from the finished grade to the top of the pole.

 

Table 5-8-1: Maximum Height for Light Poles
Location, Development Type, or Type of Light	Maximum Height, (ft.)
Bollard and pathway luminaires	4 ft.
Residential zone districts and HPO zones	12 ft.
Within 100 feet of Residential zone districts	16 ft.
Mixed-use development or allowable uses in the Offices and Services Sub-category of Table 4-2-1	20 ft.
Allowable uses in Table 4-2-1 in the following categories: Civic and Institutional Uses Commercial Uses other than the Offices and Services Sub-category Industrial Uses	25 ft.

 

5-8(E)(4)   Façade, Wall/Fence, Landscape Feature, or Sculpture Lighting

Lighting to illuminate vertical surfaces to help people navigate and detect threats at night shall follow all the following requirements.

5-8(E)(4)(a)   Non-white colored lighting is allowed for lighting vertical surfaces.

5-8(E)(4)(b)   Articulated lights emitting light above 90 degrees from the nadir shall be shielded to contain light to their targeted surface/object. Windows in a dwelling are not allowed to be a target.

5-8(E)(5)   Steps, Stairs, and Pedestrian Walkway Lighting

Lighting to illuminate trip and fall hazards such as stairs, curbs, and raised pavement shall follow ANSI/RP-43 standards.

5-8(E)(6)   Deck and Outdoor Dining Lighting

5-8(E)(6)(a)   Lighting used to illuminate patios, decks, balconies, terraces, gazebos, pergolas, or any other accessory structure, including festoon lighting, is subject to an outdoor lighting curfew.

5-8(E)(6)(b)   Festoon lighting is exempt from the point light source restriction in Subsection 14-16-5-8(E)(4)(a).

5-8(E)(7)   Security

Security lighting shall not be used continuously as a general deterrent during outdoor lighting curfew. Lighting to boost illumination levels for security as the primary objective, as described in IES G-1 Security Lighting, shall meet all of the the following requirements.

5-8(E)(7)(a)   Security lighting controlled by a motion sensor shall turn off or return to a dimmed level no more than 10 minutes after motion was detected.

5-8(E)(7)(b)   Security/surveillance cameras emitting infrared light are allowed.

5-8(E)(7)(c)   Illumination different from ANSI/IES standads may be reviewed and decided by requesting a Site Plan - EPC pursuant to Subsection 14-16-6-6(I) and providing an outdoor and site lighting peformance analysis pursuant to Subsection 14-16-6-4(H)(3).
