The Mayor is thrilled and we have seen a noticeable difference in so many areas including litter reduction, and increased recycling in the use of the bins. The on-time delivery schedule and implementation of the BigBelly units worked well. They are well received by the community and we have had very few problems with vandalism and graffiti.” “The project is working according to plan in terms of reducing collections while actually increasing capacity and adding recycling downtown for the first time.” “The City plans to purchase 250 more for the neighborhood commercial corridors using a beautification grant.” Mayor Michael A.
