Cottages at Riverton
Exterior lighting for the Cottages at Riverton has been selected to enhance the aesthetics, safety, and
security of this neighborhood. In general, full cut -off lighting is used to reduce glare and to avoid light
trespass onto adjacent properties and into residences. Full cut -off lighting does not emit light above the
horizontal plane, instead, it directs light downward. An exception to this application is the lighting at
residential porches. In this case, a low- energy luminous fixture is provided to assist in wayfinding (i.e.,
enter here) and provide a welcoming glow.
Light Sources: Lighting will utilize metal halide for post- mounted fixtures and compact fluorescent for
building- mounted fixtures to provide high - quality white light. Using metal halide instead of high -
pressure sodium (HPS) will provide better color rendering,
which can enhance the feeling of security.
Streets: Streets will be illuminated to levels as noted in the
Illuminating Engineering Society of North America (IESNA)
Recommended Practice for Roadway Lighting. Streets
internal to the project will be lit to a minimum average
maintained illuminance of 0.4 footcandles, with a
maximum /minimum ratio not to exceed 6:1.
The fixture will a full cutoff luminaire, with a height of
approximately 15 feet. The selected fixture is the Eurotique
Munich Series.

Walkways: Walkways will be illuminated to levels as noted in the IESNA
Recommended Practice for Exterior Environments. Walkways separate from
adjacent streets will be lit to a minimum average maintained illuminance of 0.5
footcandles, with a maximum /minimum ratio not to exceed 10:1.
The fixture will be a full cutoff luminaire, with a height of approximately 12 feet to
reinforce a more pedestrian scale. The selected fixture is the Eurotique Munich
Series, with post -top mounting to provide design continuity throughout the project
while differentiating pedestrian -only spaces from streets.
Residential Entry: Lighting at residential entries will provide a soft, glowing
light. The selected fixture is the Visa Midland ceiling mount with compact
fluorescent tamping.
