Annexation Cover Opens in new windowThe City of Manchester is pursuing the annexation of an area of unincorporated Saint Louis County.

The City of Manchester is inviting our neighbors to the east to join the City through annexation. Annexation is a long process, ultimately in the hands of voters living in Manchester and the unincorporated area that the City seeks to annex. While a vote will not take place until at least 2023, we are starting the conversation now - and you’re invited!

The City recently compiled a special edition of the Manchester Message that was mailed to residents within the unincorporated area that we are pursuing to annex. Click on the cover on the right to read a digital version of this Message! 

We believe neighbors in the City of Manchester and the annexation area already enjoy many strong connections. Our lives intersect in meaningful ways on a daily basis through our schools, houses of worship, where we shop, and where we play. Joining the City of Manchester with our neighbors in this adjacent area of unincorporated St. Louis County is a natural and logical next step in strengthening the community and infrastructure we share.

The City of Manchester invests in the high quality of life enjoyed in our area through excellent services, police protection, and a hometown culture that lessens the distance between us.
