Description

When designing a lighting system for residential streets, there is a wide spectrum of criteria to consider, including local jurisdiction regulations for both light levels and trespass and the desires of the community as a whole. This document will attempt to provide the designer with typical criteria and guidelines and provide a step-by-step procedure for developing a safe and friendly lighting environment. IES DG-21-15 should be viewed in conjunction with the main recommended practice for the current version of ANSI/IES RP-8-14 American National Standard for Roadway Lighting. It is intended to be used to assist the designer in developing a lighting system for residential streets that will meet the standards and criteria set out in ANSI/IES RP-8-14 along with local ordinances and concerns for landscape design. There are many general objectives that can be achieved in a residential street lighting installation. A few of these are listed here: • Pedestrian and driver safety • Obtrusive light control • Minimized power usage • Community and neighborhood ambience • Crime reduction • Comfortable use of residential neighborhood streets after dark
