Which outdoor lighting zone is characterized as the darkest and is often designed for government parks?

The correct choice refers to Zone 1, which is characterized as the darkest outdoor lighting zone. This designation is particularly relevant for areas such as government parks where minimal artificial lighting is desired to preserve natural night-time conditions. Zone 1 is designed to minimize light pollution and often emphasizes the use of dark sky-friendly lighting techniques.

In such a zone, the intention is to create a serene and natural atmosphere conducive for wildlife and the local ecosystem while providing enough light for safety and navigation only where absolutely necessary. This aligns with the principles of sustainable landscape architecture that prioritize ecological balance and minimizing human impact on natural environments. Therefore, Zone 1 serves to enhance the experience of the outdoor space while also addressing environmental considerations.
