This bill would require the Department of Transportation (DOT), when installing a new or replacement street lighting fixture on a residential street, to install a shielded fixture that is controlled by a motion sensor to automatically dim at certain times, subject to certain exceptions. DOT would also be required to conduct a study on the possible citywide use of shielded street lighting fixtures that utilize adaptive lighting controls. Until the completion of such study, DOT would be required to submit annual reports regarding its progress on such study, as well as on the installations on residential streets.
