Local political group PLAN-Boulder County on Tuesday withdrew its request for a hearing to oppose a decision by the Boulder city attorney to decline to approve a petition for this year’s ballot it was hoping to start circulating for voter signatures.

The withdrawal occurred just hours after the hearing had been scheduled for next week.

The petition was crafted by the group that was planning to try gathering thousands of signatures from Boulder voters for a November citywide vote on a measure, that, if passed in the election, would guide the terms of the annexation of the CU South parcel, south of the city where the University of Colorado Boulder plans to build new facilities in the future.

The group initially had intended to challenge the ruling on its petition that was based on advice of City Attorney Tom Carr that the deadline to turn in signatures for a ballot measure of that sort had already passed June 5. After the hearing was scheduled, Peter Mayer, co-chair of PLAN, emailed the city clerk’s office and pulled out of the hearing, according to a copy of the message shared with the Camera by Carr.

“We are formally withdrawing our request for a quasi-judicial appeal and the separate motion submitted earlier today. We have received sound advice that our efforts are better spent focusing on next year. I sincerely apologize for the inconvenience,” Mayer wrote.

PLAN’s proposed requirements for an annexation agreement with CU Boulder included a 500-year flood mitigation plan for South Boulder Creek and limiting development to 87 contiguous acres. City Council last month moved forward with a plan for a 100-year flood mitigation project, and CU Boulder has stated it needs 129 acres of the 308-acre property for development.
