Sign Up to Get Trees this Spring! Sign up with SDEV or the City of Detroit to get trees for your neighborhood. SDEV needs residents to let us know where you need shade, dust blocked, or fruit trees planted. Send an email to firstname.lastname@example.org with the subject “Trees” or leave a message at 313-842-1961 . Include in the message your full name and contact info, the location of the tree, and any other details you’d like us to know.
