News & Updates

LEVEL 1 CLOSURE NOTICE:  March 11th- April 15th

Level 1 will be closed for 5 weeks beginning on Monday March 11th to allow us to make necessary floor repairs and to resurface the entire level.  Our long-time customers know we plan to repair and recoat one level each year.   With 220 fewer spaces available, we expect to be full between 10am and 1pm on Tuesday –Thursday during the repair period.  Our Preferred Card holders are guaranteed parking, even when the Garage is full.  We do encourage all other customers to arrive earlier on these days, or to consider parking on Mondays or Fridays if your schedule allows.  We will have valet staff onsite to accommodate as many customers as we can, but please do allow extra time during these times.   We apologize for the inconvenience and thank you for your patience while we make improvements to the Garage. 

Jayne’s Flowers is in our lobby on Tuesdays, Wednesdays & Thursdays from 11:00 AM – 6:00 PM. 

Dirty Windshield?  We installed a windshield washing station on our Lobby level near the tire inflation station.  

 

     Going Even Greener and Leading the Way

While many businesses were hibernating during the pandemic, we installed 30 more Level 2 Electric Vehicle charging stations, bringing our facility total to 41 stations! Our stations are part of the Chargepoint network. There are eleven on the Lobby Level and six near the elevators on each of Levels 1-5. There is no fee to use the stations, but regular parking rates apply as you exit the Garage. In order to provide access to the stations, EV’s must be moved to regular parking spaces once fully charged.  In February 2024, 411 unique drivers used our stations for 1,324 charging sessions!   We have avoided more than 578,086 kg of greenhouse gasses, the equivalent of planting over 14,823 trees and letting them grow for 10 years. 

Post Office Square is mitigating 100% of its electricity footprint with renewable energy under a 25-year Power Purchase Agreement, partnering with MIT and Boston Medical Center, to purchase all of the output from Summit Farms, a solar project in North Carolina. It is the largest renewable energy project ever built in the US through an alliance of buyers and in aggregate, the expected 146 gigawatt-hours of emissions-free power per year will result in the abatement of 119,500 metric tons of carbon dioxide emissions — the equivalent of removing 25,250 cars from the road.

Why is Blue Green?

To conserve drinking water, The Garage at Post Office Square has recently installed an Integrated Water Management & Green Infrastructure system which uses reclaimed groundwater to flush our toilets. We use a blue dye to easily identify the non-potable water.

Integrated Water Management & Green Infrastructure

The Garage at Post Office Square pioneered several novel and award-winning construction technologies. As part of our sustainability effort to conserve resources and enhance efficiencies, Friends of Post Office Square has invested in an innovative system which allows the Garage to use much less water, without minimizing our first-class building operation.

The seven-level Garage extends 80 feet beneath the street to a depth where groundwater saturates the soils. In order to prevent flooding, groundwater is collected in a deep well beneath Level 6. Since the Garage opened in 1990, excess groundwater in the well has been pumped into Boston’s combined stormwater/sewer system.

Our new groundwater reclamation system allows us to re-utilize the groundwater to flush the toilets and wash the floors in the Garage, reducing the amount of high-quality drinking water the Garage uses in its operation. We are saving thousands of gallons of drinking water every week, water that is transported to Boston all the way from the Quabbin Reservoir in Western Massachusetts. By using the groundwater before it is pumped off-site, we are also dramatically reducing the Garage’s sewer output.

Our project conserves drinking water, recycles the local groundwater that is pumped for dewatering, reserves treatment capacity at the MWRA treatment plant at Deer Island, and reduces our annual water and sewer bills by more than $10,000. The design is an example of Integrated Water Management and Green Infrastructure – a new way of thinking about our water resources. It focuses on sustainability of resources: using local sources of water and re-thinking our use of limited high-quality drinking water for non-potable purposes.
