Chilmark selectmen took up a series of summer housekeeping items this week, approving the Chilmark Road Race, wrapping up harbor repair projects and reviewing advertising bylaws.

The selectmen approved the annual road race at their weekly meeting on Tuesday with one requirement: There must be more portable bathrooms throughout the course.

Delayed state approval for 2012 property assessments will force the town of Chilmark to operate on borrowed money for the early part of the fiscal year, the selectmen learned this week. Without certified assessments from the Massachusetts Department of Revenue, the town cannot set a tax rate, and without a tax rate it cannot send out property tax bills for the second half of the year. Preliminary tax bills for the first half of the year went out in October.
