Dark sky Wildomar, a standard for preservation

I'm using the Milky Way as a metric for local light pollution. I don't expect to restore the skies of ten years ago, rather, I hope only to keep the Milky Way visible from typical backyards. Below is a photo of the Milky Way on August 12, 2010 from my backyard. Though the contrast is poor, our galaxy is still visible to the naked eye and to the camera.

Photo: Region near Sagitarius and Scutum.
