The Knoxville City Council is looking to tackle weed problems at Auld Park and near the Recreation Center.  City Manager Dick Schrad says the council received a proposal on getting a professional to apply weed killer to those areas.  But Schrad says the council wanted to compare that cost with the city getting its own equipment and having city employees certified to apply the chemicals.  Schrad says a proposal on the estimated “in-house” weed killer application is expected in the future.
