Was your property included in the 2017 Municipal Annexation Policy / Plan area?
As a result of changes to state law, the City of McKinney will be amending its 2017 Municipal Annexation Policy over the coming months to ensure conformance with new changes to Chapter 43, which will go into effect later this year.

Did you receive a letter from the city informing you of upcoming annexation and/or a development agreement? See below to learn more about what this means for you. 

During the August 28, 2017 Special Meeting, McKinney City Council approved Resolution 2017-08-160, identifying a preferred approach for carrying out municipal annexations for the remainder of 2017.  

Over the next several months, the city is also taking a strategic approach to annexing property based on sound municipal planning principals while keeping residents and long-term fiscal responsibility in mind. 

As it has with previously strategic annexations, City Council is offering a development agreement to properties with existing wildlife management, timberland and agricultural tax exemptions as authorized by state law. These agreements would allow properties to remain in the city's extraterritorial jurisdiction (ETJ) for a period of 5 to 10 years in exchange for the property owner agreeing to limit the use of the property to agricultural purposes.
