CAMBRIDGE – Sometimes people just get together to make something good happen.

When Donna Towers, a resident of Cambridge Landing, noticed that landscaping in three downtown traffic medians had begun to look worn, she began talking to neighbors about fixing things up.

“I solicited money from all around here – residents and business owners,” Ms. Towers said Nov. 15 as a group of volunteers unloaded gear and prepared to start work.

She said she also coordinated with the Cambridge Police Department, City Commissioners and Cambridge-South Dorchester High School seniors. “We’re trying to pull everybody together to beautify this part of town,” Ms. Towers said.

Dante’ Meekins, Blake Brooks, Jerry Zhuang and Jeremy Curry are seniors at C-SD, who gave their time to help them meet the 75 hours of community service required for graduation.

“We couldn’t do it without them,” Ms. Towers said. For them to come out on their day off, I appreciate it.”

The three medians are on the west side of the drawbridge over Cambridge Creek. Plants, mulch and oyster shells were placed there originally by a group called the Green Team, Ms. Towers said.

Plans now are for the mulch and shells to be removed. Then, a few plants will be placed, followed in the spring by blooming annuals.

All of it is being done by volunteers, using private donations. “It’s not going to cost the city or the taxpayers anything,” Ms. Towers said.
