Subject: My mistake on previous note.
In looking at my June 12th email, I realized that several of the comments I made were based on my viewing an older
version of the "Sediment Basin Plan ". I even noted that I was viewing the September 13, 2013 version and you may
have caught that. Therefore, please forgive my inaccurate memo and ignore the following comments:
• On #2, 1 mentioned that I could not find the forebay. I do now see the forebays in the 2/16/14 version.
• On #3, 1 mentioned the "volume provided in the filter area is 13,710 cu. ft." I think that that the 13,710 figure
was from an old drawing. However, the "Water Quality Notes and Calculations" do show a volume in the pond
of 11,060 cu.ft. and the drawing indicates a storage of 12,606 cu. ft. There may be some confusion because of
the forebay volume but I'd appreciate you checking on that.
• Please ignore #4 on the underdrain and filter fabric. I was looking at the earlier version of the drawing.
• Please ignore #10. You found the slope error and corrected it.
I feel much better about the submittal now that I am looking at the updated drawing. I apologize if my mistake caused
you any additional work.
I am, however, having some difficulty seeing the elevation lines (above the 3675.5 line) around the pond and would
appreciate you sending the 2 -6 -14 drawing in a PDF version. Also, I'm not sure if this is an issue but the bottom of the
drop inlet #1 of forebay #2 looks like it will be flooded at the design storm event. This may be your only option but you
might check on that. (PS. Any other drawings, like the drainage area delineation, can also be submitted by PDF.)
I will be out on vacation on Monday the 301h and return on July 14th. I will be in the office some tomorrow and most of
the day on Thursday and Friday. If you feel like you could benefit from talking to me before I go on vacation, please give
me a call.
