Somerville Climate Action is sponsoring two "de-paving parties" in June.

If you don't know what de-paving looks like, check out this time-lapse video.

As you all know, Somerville is the most dense city in New England, and much of it is a concrete jungle. A number of home owners in the city want to rip up the pavement on their property and replace it with grass and gardens.

Somerville Climate Action helps people do that with de-paving parties. Volunteers come with pickaxes, sledgehammers, wheelbarrows, food and some good tunes, and they cut up the pavement and cart it away.

There are two de-paving parties scheduled for June:

• Saturday, June 2: 1 p.m. to 4 p.m. at Gail Strickler's house, 50 Francesca Ave. (near Davis Square)
• Saturday, June 16: 12 p.m. to 3 p.m. at John Ringeling's house, 15 Vinal Ave. (across from the Growing Center)

If you want to volunteer, you can sign up here.

Somerville Climate Action is also planning more de-pavign parties later in the summer. You can visit their website here.
