There is a city of Waltham storm-drainage easement at the border of our property on Winthrop Street. Following hurricane Irene, a large sinkhole developed in our backyard, next the city drainage system . A large tree next to this manhole shifted, and is now leaning over this sinkhole.

We have been in continuous correspondence with the city engineering department over this matter. City staff who have visited the site, are in agreement that the manhole is broken, that the sinkhole is due to the break in the city drainage system, and that it is the responsibility of the city  to repair the storm drain, and the damage to our backyard. However, we were told that the city is unable to budget the funds for such repairs, so nothing was done. Meanwhile, the sinkhole continues to enlarge after every rainstorm.

What is a resident of Waltham to do?

 

 

In Response to Re: Sorry State of storm drains in Waltham:
The storm drains are appalling all over Waltham.   I don't know why the city isn't doing more to keep up with them.  Blocked storm drains
cause wet basements to many people.  Trying call the Mayor's office.  You shouldn't have to, but that seems to be the only way to get the problem addressed. 
The city website has a section to address sink holes and pot holes.  You will have luck there.
