Background on Pima County’s Lighting Code Update

Pima County has been diligently working on updating its outside lighting code, collaborating with the City of Tucson and the Fred Lawrence Whipple Observatory representatives. This move aims to address the longstanding issue of light pollution, which has significant implications for astronomical observatories in the area.

Historical Context and the Need for Regulation

The first ordinance to curb artificial-light pollution dates back to 1972, recognizing the significance of preserving dark skies for the state’s federal and university observatories, many of which are located within a few hours of Tucson. This historical context underscores the importance of regulations to mitigate the adverse effects of excessive outdoor lighting.

The Forum on Light Pollution Education

The Green Valley Council’s Planning and Architecture Committee is organizing a forum in January to educate residents about the impending changes in the lighting code. This educational initiative aims to raise awareness about the impact of light pollution and inform the public about the importance of compliance with the updated regulations.

Importance of Public Education and Community Discussions

During recent discussions within the GVC committee and community members, emphasis was placed on the significance of educating the public, especially homeowners associations (HOAs), about the revised code. Committee Chairman Bill O’Malley highlighted the observatory’s proximity, indicating that Green Valley resides in stringent areas subject to light restrictions, and anticipates the new code to be more restrictive.

Strategies for Mitigating Light Pollution

Ellen Cox emphasized the need for continuous education efforts, proposing that HOAs provide informational materials to new residents. Chris Balka advocated for education on light color, brightness, and direction, stressing the importance of directing light downwards instead of outward. Moreover, Balka suggested launching a campaign to encourage local stores to carry “dark sky-approved” light fixtures.

Beyond Stargazing: Impact on Wildlife

Pam Weston of Canoa Canyon Estates highlighted the broader consequences of light pollution. It’s not merely about stargazing; it also adversely affects local wildlife such as birds and bats. This aspect underscores the multifaceted impact of excessive outdoor lighting on the environment beyond human concerns.

Statistics and Research on Light Pollution Impact

Studies have shown that light pollution disrupts ecosystems, affecting animal behavior, migration patterns, and the reproduction of various species. According to research published in the Journal of Animal Ecology, artificial lighting at night can interfere with crucial ecological processes and contribute to population declines in certain wildlife species.

Conclusion

Pima County’s efforts to update its lighting code underscore the growing awareness of the detrimental effects of light pollution. Through education, revised regulations, and community involvement, the county aims to strike a balance between human needs for outdoor lighting and preserving the natural environment for astronomical observation and wildlife conservation.
