The Murfreesboro city council took care of some much need maintenance at their December 15th meeting.  The Street & Sign Department's street sweeper engine will have to be replaced at a cost of about $10,000, and the city renewed their annual contract for traffic signal maintenance, which includes upkeep to everything from traffic lights, to school zone signs and traffic cameras.  City Hall continues to be retrofit with energy efficient upgrades, and a 3 year lease was signed for a property along South Rutherford Boulevard, to be used by the Criminal Investigations Division of the Police Department.  That building will now house additional office space, interview/interrogation rooms, evidence processing areas, as well as conference rooms and storage space.  In addition, the department is set to upgrade their gear as well, setting up to order nine new vehicles as well as extra communications systems and electronic equipment.  Finally, the weeks-old amendment restricting building height was finally passed through upon third and final reading, and three public hearings were held, the first to approve a certificate of compliance for Stop-N-Shop Discount Liquor & Wine on St. Andrew's Drive, the second to consider rezoning 50.92 acres along SE Broad Street, and the final, an application from Mr. Peter Demos to rezone 0.42 acres on North Maney Avenue from residential to commercial, to renovate the property to serve as the new location of their main office buildings.  A public hearing to consider rezoning 0.4 acres along East Main Street has also been scheduled for January 12th.
