I am working on updating our landscaping and screening ordinance. Currently we require 1 tree per 10,000 sf of parking lot area. We are proposing to increase that to 1 tree per 6,000 sf of parking lot area. I am putting together a comparison of other cities. I am interested in all cities but cities with the same climate would be most effective. We are also proposing to increase the minimum planting area around each tree from 36 sf to 50 sf.
Can you tell me what the requirements are in your areas relative to trees per parking lot area (or per parking space) and include the minimum planting area for each tree?
I am in the eastern Nebraska/western Iowa area.
Thanks for your help!
