You are correct. I was measuring with the wrong scale.

Kent,
I think it is just a typo, but this cross section should be in the neighborhood of 31 feet at the narrowest, correct?
Thanks - Josh

Josh and Alan,
Attached are two documents regarding the revised cross slope for WS Phillips Parkway as we discussed earlier
today. We have applied the new cross slope (2.5 %) using the same spreadsheet that is normally used for this
calculation in our drainage report. The half street that we are building now is 42 feet wide at its narrowest. The
spreadsheet shows a maximum spread of water of 10.19 feet using the revised cross slope. Thus we conclude that it
will still allow one lane of traffic in each direction under this revised design. If you concur with our figures, please
let me know so we can proceed with the construction. Thanks for your consideration on this.
