The Seattle Post-Intelligencer (Greg Johns) reports: Attorneys for the city of Seattle and Clay Bennett’s Professional Basketball Club agreed Wednesday to extend the deadline for completing the settlement agreement that allowed the Sonics to end their KeyArena lease and move to Oklahoma City. The PBC and city initially set an Aug. 1 date to wrap up their July 3 settlement, but now have asked Judge Marsha Pechman to extend that to Aug. 18. Additionally, Pechman’s original Order of Dismissal listed Aug. 6 as the deadline to reopen the case. That date now would be Aug. 25. The additional time is needed in part because of the possibility of a voters’ referendum on the City Council’s approval of the settlement.
