The Murfreesboro City Council is cracking down on overgrown yards, passing an aggressive new measure at their July 14th meeting.  The new ordinance provides that if the city finds an unkempt lawn, the city may go in and mow the yard and then bill the resident for the service. The homeowner could also be cited in city court, which includes a $50 fine plus any court fees.  The mayor announced a community meeting to discuss the upcoming bicentennial celebration, to which anyone can contribute, to be held on July 21st, 10a.m., at Patterson Center.  Evidently remembering last year's shortage, the Street & Sign Department Director requested additional orders of roadway salt, 932 tons to be exact, and Presidio Networked Solutions was hired to provide technical support and enhancements for the city's new fiber-optic network infrastructure, recently constructed by Comcast, which allows for streamlined data communications between buildings at various locations.  The Water & Sewer Board plan improvements to Old Fort Park by elevating the walking trail over drainage channels, and requested the city's help in reducing the growth of Parrot's Feather, an invasive plant found in the wetlands area of the Discovery Center.  The council also executed a grant contract with the Transportation Director, which will allow the city to draw funds from both the state and the Federal Transit Administration to use towards further expansion of the Rover system, and to covering past costs incurred on public transportation.  Chief of Police Chrisman requested 21 new video systems for inside department patrol vehicles, and, bringing the department into the new age, 50 tablet computers for the Criminal Investigations Division, to expedite the on-scene collection of statements and evidence.  Finally, four public hearings were held, to rezone an area north of Kimbro Road and west of Barfield Road, and along Memorial Boulevard to residential districts, and to rezone 49.2 acres along South Rutherford Boulevard to a residential multi-family district, presumably to build a new apartment complex, as University Villas was the applicant.
