Paducah city commissioners introduced ordinances for two major renovation projects at their Tuesday night meeting. One continues the second phase of the Noble Park swimming pool renovation. It will include gutter and drain replacement, filtration, disinfection, pumping and other repairs. Bidding for the third phase starts in early 2013. The other authorizes the start of renovation on the Market House building and the River Discovery Center. Commissioner Gayle Kaler says she worked with the city manager and the city engineer-public works director for two years to get the buildings repaired.
