Here is a link to a Neighborhood Watch Sign Request Form. The form allows for request of multiple signs, so ask your neighbors if they would like a sign too. You can submit your request in two ways:
1) Fill out the form I’ve provided and mail it in to:
St. Louis Street Department
1900 Hampton Ave.
St. Louis, Mo. 63139
Att: Kim Coleman Or
2) Email Kim Coleman directly at firstname.lastname@example.org
Make sure in your email to include what hundred block you would like the sign(s) and in front of what specific address or addresses you want them posted.
