LED Lighting SSPs to Reduce Ecological Impacts on Terrestrial Wildlife

Summary

In this project we will develop tools and guidelines that allow for the smooth integration of environmental analysis of artificial light at night into Caltrans practices and workflows. This effort will be focused in four areas. First, the project will bridge the gap between biologists and environmental review professionals and lighting engineers during the project design phase, by demonstrating and working through case studies where new lighting is being proposed. Second, it will make recommendations about the taxonomic resolution at which spectral tuning should be considered as an environmental mitigation approach so that such recommendations can be incorporated effectively into standard plans and specifications. Third, it will consider and make specific recommendations for standard special provisions regarding lighting in Caltrans projects, which will focus on spectrum, lighting distributions, and shielding. Fourth, it will review the issues associated with temporary area lighting and make recommendations for standard provisions to reduce the impacts of lighting from nighttime construction.
