Manhole 6883 at Lake Roland
“Manny” the manhole at Lake Roland was repaired after it blew in August, 2019.

Want to learn about sanitary sewer overflows in the flood plain at Lake Roland? Since the big overflow at Manhole 6883 in August 2019, the manhole has been repaired, but the addition of more toilets, showers, and other sewer volume have been added upstream of the Jones Falls sewer system. GTA members will hike into the wetlands on the West Bank of the Jones Falls River to learn where this manhole is. Then you can drive on Lakeside Drive into Lake Roland Park to keep an eye on this manhole after heavy rainstorms. We are happy to show you where to walk and what to watch for.  We will all wear masks and socially distance from people who are not in our own family. This news article explains what happened in August, 2019.

Wrap Young Native Trees with mesh to protect them from Cicada Brood X

Weekends of April 17-18 and 24 – 28

A 17-year Cicada.

Help wrap young trees’ branches with fine mesh so cicadas can’t harm the twigs and weaken and possibly kill the trees. The trees planted in our Neighborhood Native Shade Tree program in 2019 and 2020 (in liaison with Bluewater Baltimore) are the greatest risk from cicada damage in Aigburth Manor, Anneslie, Knollwood, Lutherville, Stoneleigh, West Towson and other neighborhoods. Masks and social distancing from people not in our own families are required. Please message us on the GTA Facebook page, or email us at if you’d like to pitch in with this effort.
