About CU South

With the approval of the Boulder Valley Comprehensive Plan Update in 2017, the City of Boulder and Boulder County approved new land use designations pdf and  guiding principles pdf for the CU South property. The guiding principles are now incorporated into Chapter 5 of the comprehensive plan and will be used to guide future decisions around annexation of CU South. The city is working to determine the conditions of annexation for “CU South” under which the University of Colorado’s South Campus would fulfill both the desires of the University system and meet the goals of the City of Boulder. The annexation agreement will be guided by the BVCP CU South Guiding Principles, and a modified annexation process that will provide opportunities to influence the annexation terms through city boards and commissions and the city council meetings.

If annexed, the CU South would come under the city's jurisdiction like the other campuses. Utility services also could be extended to the site. Annexation would  not  mean the city would own the site. Visit the CU Boulder project web page  for frequently asked questions and more.  


  • 1996:  Flatiron Companies sells the CU South property to CU Boulder (previously used for sand/gravel mining).
  • 2000 – 2015:  In response to requests by the university, the city opts to not consider changing the comprehensive plan land use designations for CU South until the “South Boulder Creek Floodplain Study is completed and there are further discussions with the university on the proposed development for the site.”
  • 2015:  City Council approves the South Boulder Creek Flood Mitigation Plan. The plan includes regional detention of flood water upstream of U.S. 36 on the CU South campus and along Colorado Department of Transportation right of way. With the flood mitigation plan adopted, the city reinitiates land use designation changes as part of the 2015 BVCP Major Update.
