We have a client with a flag pole and they would like to leave a flag pole light which shines from the ground up to the flag. Is there an exception to the light tresspass or night sky issue?

Our project site has a foutain/pond that has underwater lights. They are about 500 watts but down't really illuminate the surrounding areas.

Has anyone had any experience on how to document this credit for buildings that have parking garage space taking up the first several above-ground floors of a large office tower?
