That's an excellent and practical question! The answer is: it depends entirely on the specific bench and how it's installed. In modern urban planning, the mobility of park furniture is a key consideration for maintenance.
Many cities now intentionally install benches that are designed for relatively easy relocation. These are often secured with simple, removable anchor systems like bolts into concrete footings or sleeves in the ground. Public works crews can quickly unbolt or lift them using small equipment when scheduled street sweeping or snow plowing is due. This proactive design prevents damage to both the benches and the maintenance machinery.
However, you'll also find older, permanently fixed benches. These are typically cemented deeply into the ground or welded to permanent bases. Moving them is a significant task requiring construction equipment and is usually not done for routine cleaning.
For snow removal, the protocol is crucial. In heavy snow areas, municipalities often have a map and schedule for bench removal or temporary relocation to designated areas. If a bench isn't moved, snow plows must navigate around it, often leaving piles of snow and creating inaccessible spots.
So, while not *all* park benches are easily moved, contemporary urban design strongly favors movable or semi-permanent solutions to facilitate efficient city maintenance like street sweeping and snow removal, ensuring cleaner and safer public spaces for everyone.
