No person shall erect or maintain any sign or signboard extending over any street, alley, sidewalk or other public place without having first obtained a permit therefor. Permits for such signs shall be issued by the clerk and shall state the location of the proposed sign.
All signs extending over any sidewalk, street, alley or other public place must be securely fastened and constructed so that there will be no danger of the same being dislodged by ordinary winds or falling from any other cause.
The lowest part of any sign or its support which extends over any public way shall be at least eight feet (8') above the level of the walk or public way over which it extends; but no sign shall be maintained over any public way used by vehicles if any part of its support or of the sign is less than fifteen feet (15') above the level of such public way. (1928 Code §111)
