Hales, his office says, is moving his boat to California and couldn't rearrange his schedule. "Moving the trip dates, or the Springwater start date, would have been very difficult with the amount of planning that went into both," writes spokesman Brian Worley in an email. "If the mayor had moved the planned coordinated cleanup solely based on his trip, that would be an incredibly irresponsible use of city resources. With the amount of coordinated planning prior to the mayor's trip, the mayor's actual physical presence for the cleanup is unnecessary for the work to proceed."
