The Boston area experienced 62 events in 2021 (down from 212 in 2018). As of 2022, local utility company Eversource is replacing 38,000 maintenance hole covers, starting in high-traffic areas, with a safer design. A rail allows the cover to lift up to 4 inches (100 mm) and let gases escape, but prevents it from flying into the air and damaging buildings or cars or injuring pedestrians. In some places where road salt is not a concern, the covers have vents to let gases escape. To prevent and mitigate safety problems, the company is also installing monitoring equipment to detect dangerous gases and fires, and increasing inspection frequency.[15]

Do no block the manholes!
The Sanitary Authority requires free and clear access to its manholes in case of emergency. Covering or placing decorative planters on top of manholes makes them difficult to locate in adverse conditions.
Heavy planters could inadvertently be damaged by Sanitary Authority staff attempting to move them. More importantly, lifting heavy planter could injure workers in their attempts to access the manhole for maintenance or in the event of a backup. CTSA Rules and Regulations governs the policy for excavation and raising of buried manholes to grade.
Utilizing standing bike racks promotes cycling, which has numerous environmental benefits. With increasing concerns about climate change and urban air quality, encouraging more people to cycle instead of driving can significantly reduce carbon emissions and traffic congestion. Cities equipped with efficient bike storage solutions like standing bike racks are more likely to see an uptick in bicycle usage, contributing to a healthier environment and fostering a culture of sustainable transportation.
- Prevention of Flooding During heavy rainfall or snowmelt, excess water can quickly accumulate on surfaces, leading to potential flooding. A 6% wide trench drain efficiently diverts this water, protecting structures and landscapes from damage.
