Tax revenue has increased for the third year in a row in Union Gap. City officials say the extra money will help pay for a temporary city hall. Union Gap pulled in $3.7 million in sales taxes last year. That is about $500,000 more than 2010. City officials say that extra money helped pay for the new city hall modular unit. One woman wants some of the money spent on projects like improving parks. Union Gap says the sales tax revenue also went to new streets and the water system.
