Subject: Re: Copper Falls - Calculated 100 Year Water Surface
The words "was unchanged." were lost ....
If you want, I can send you the ras files (which are pretty neat) showing the little storage area and lateral
structure, and then you can see the output hydrographs and calculations... but it just shows "no change" which
is what you wanted to see in the first place. (and we'll have problems with Ass paths because the hydrological
input is in a different directory....)
Please call me if you want more stuff.

To best analyze the effect of the little bit of fill in the calculated water surface, I converted the HEC-RAS model
to an unsteady model and modeled the effect of
1. the storage as a storage area, and
2. the effect of the new impervious cover as a separate hydrology analysis.
I have attached the output table showing the post construction water surface and the pre -construction water
surface.
Per your request I have attached the grading plan which shows the erosion control plan.
Please call me if you need something else.
Thanks
Joel

Hi Joel,
When you send the email regarding the 1.1" rise in BFE, please include Grading and Erosion Control Plan so I
can print one for Donnie's inspections.

Veronica ... Considering the use of the development, the associated trips, the full two lanes of the frontage road with shoulders and the
geometry, a deceleration lane is not mandatory for this location.

Chad,
thanks for talking with me regarding our office building project. As you can see on the attached site plans and T1A letter we have very
little traffic impact from this office use. If you could send me an email back for my records regarding your requirement (or not) for a
decel lane on SH6 frontage for this project i would appreciate it.
