The Lawrence Chamber of Commerce may soon weigh in on the city’s proposed sales tax increase. The chamber on Wednesday afternoon sent out an e-mail to its members asking them to participate in a survey asking whether they support the three sales tax questions that will be on the Nov. 4 ballot. The message says the chamber’s board of directors will meet next week to decide whether to take an official position on the three sales tax questions. Previously, chamber leaders had said they were not sure whether the organization would make an endorsement in the election. As a reminder, voters will be asked to decide three sales tax questions:¢ Question No. 1: A 0.30 percent sales tax for streets and infrastructure. ¢ Question No. 2: A 0.20 percent sales tax for transit operations. ¢ Question No. 3: A 0.05 percent sales tax for expanded transit services and new transit equipment.
