Andrew,
The city has been approached by the developer of the Nancy J. Petterson property about the possibility
of adding an additional inlet on the north side of Sandy Lake at or around station 84+75. This would
allow them to slope their street down from Sandy Lake, but not take on any of the water in the
gutter. They are asking us to price this addition through the contractor, but before we do that I wanted
you to give a cursory review of the drainage design to ensure we would not cause a capacity problem in
the system if we picked up this water at that location.
Since line F is already in place, a capacity problem that would require us to increase the pipe size would
now involve removing and replacing a portion of the line.
Please take a look at this and give me your thoughts.
Thank you.
Keith Marvin, P.E.
