If you've driven through our town center in recent days, you've seen some massive changes! The Town Common effort is split into four phases: Site Characterization, Demolition, Remediation, and Build Out. We've now completed phase 2 the demolition phase of the project and will move on to Remediation in the spring.
Over the last 10 days we've removed the three buildings, exposed the cement cap over Great Brook, graded the building areas, and placed loam, seed and hay on top for erosion control, all in compliance with a very detailed Wetlands Order of Conditions issues by the Bolton Conservation Commission. During the grading of the property we discovered three buried heating oil tanks which were not previously identified. The first tank was a 300 gallon tank which was empty and badly corroded, the second tank was a 4,000 gallon tank with 2,663 gallons of an oil/water mixture, and the third tank was a 600 gallon tank with 550 gallons of heating oil. All three of these tanks were located within ten feet of Great Brook. From an environmental perspective they posed a significant challenge requiring Clean Harbors to pump the tanks, Trident Environmental to cut open and clean the tanks, the Bolton Fire Department to do inspection and our Environmental Consultant to do soil testing. Once all this was done we were able to remove and dispose them at a licensed recycling facility. The one benefit is that we were able to provide the Bolton Highway Department with 680 gallons of waste oil to be used to heat their garage this winter!
On the demolition side, our contractor Cataldo Landscape and Construction hauled away 187.2 tons of organic material to the Devens Recycling Center as well as 16 tons of metal to Reisner recycling and 325 tons of concrete to be pulverized and reused as fill. We also saved much of the timber framing, and wide pine flooring to be re-used in future projects. Cataldo also made a generous donation of 500 feet of granite curbing, which you can now see lining the site.
Although we have made a huge step toward our goal, we still have a long way to go. Remediation in the spring will require us to remove hundreds of yards of soil from 5 contaminated locations on the site. The soil will be replaced with clean material. Once the site has been cleaned we can start the fun process of building out our town common.
Now that we can all see the open site, we can really start start envisioning the possibilities.
