Description
Storm drain nearest fire hydrant, at intersection of Greenwich Ave. & Second Street is completely clogged. (Nearest address = 375 Greenwich Ave.) As you can see in attached photo, drain across street works fine; also drain hidden by garbage toters on left of photo (at 86 Second St.) works fine.
During heavy downpours, this intersection completely floods because of this one non-functioning drain next to fire hydrant. When water finally clears, there is nothing on the catch basin grate, and the catch basin does not have much junk in it
--so the clog is INSIDE the sewer pipe.
In the past, the clog has been located approximately under the manhole in the Second Street crosswalk:
i.e. the pipe that goes between the drain near the fire hydrant at 375 Greenwich and the drain in front of 86 Second Street (hidden by the toters in photo).

This was investigated on 8/14/15. It appears the blockage has been caused by stone chippings and mulch being washed in to the catch basin, these having been placed on the snow shelf in an apparent attempt to beautify the area by residents. This area has combined sewers, where the stormwater flows into the sanitary sewer. There are siphons at the point of entry of the storm drain to prevent odors escaping from the sanitary sewer. It is believed this is where the blockage has occurred.
As these siphons date from the 1880s, and are made of vitreous clay, they are not strong enough to withstand strong jetting. They have two 180 degree bends, and cannot be rodded either.
We are requesting whoever placed the stones and the mulch to remove them, and restore the grass that was originally present. When this is done we will jet the pipes from the catch basin. There is no guarantee this will be successful.
