Kirk Brooks To: Jane Zimmerman Cc: Alan Locke; Tim Tyler; Jeff Heilman Subject: RE: new house at northeast corner of 35th and Nassau Jane, Thanks for the info. Alan Locke and I are already aware of this problem and have been discussing solutions. Most of the runoff should go away as part of the continued construction process. The roof top will be connected to the sewer, a trench drain for the driveway runoff would be useful and grass on the exposed areas should provide the majority of relief for the issue. Some sort of infiltration pit at the low area may also be useful. We hope to discuss these things with the builder shortly.

This used to be a drainage corridor, however, almost all of the upstre,,m contributing runoff has been diverted to the combined system. Any local runoff that accumulates is essentially pumped out of the low areas by residents' sump pumps. Normally, they don't have a significant problem. However, during the heavy rains on April 16th, a lot of water came down the old swale area, and we received some flooding complaints. The neighbors are concerned about the additional impervious area associated with the new home. They are also concerned that a pond was filled in, and pipes are point discharging water at the south property line. I couldn't tell what water was being conveyed in the pipes, and I don't know what the ultimate plans are for handling runoff from impervious areas on this site. However, I think it would be an appropriate location to require this runoff to be conveyed to the combined sewer per our archaic ordinance... Also, I talked with Keith about something else I observed. During the construction of the home, the sidewalk along the north side of 35th has been disturbed. It looked to me like the runoff from the uphill sidewalk, instead of running down the sidewalk and into Nassua Street, is instead ponding and heading down into the construction site (and then downstream to the neighbors' sump pumps) instead. A berm along the north side of tile old sidewalk area, combined with a shallow ditch, would divert this water back into 3511h - which would help the problem. I'll be dealing with other aspects of the complaint, but if you would see that these construction aspects are addressed, I would be grateful. Thanks! Jane
