Walter,

 

I just thought we would designate the rest of the area from the end of the runway to Lindbergh as impervious and call it good.

 

On the second page, I think the routing needs to be revised to reflect the drainage ditch.  It will impact the drainage areas and the time of concentration for those basins although
probably not substantially, but I do think the model needs to be as accurate as possible.

 

If you have any other questions, please let me know.

 

Thanks,

Clay Barnett, P.E.

sorry, forgot the link.  Also, does your aviation department have anything on the proposed EMAS.  Looks like it will have to be shorter than recommended, which is allowable.  Just looking
to give some guidance to PK.

Clay,

 

I have been reviewing your comments.  Could you please clarify your comment on the second sheet?  Are you talking about a need to correct the flow path?

 

Thanks,

                Walter

Walter,

 

I read through the drainage study.  My comments are attached.  I believe we discussed the first and third sheet of the attachment.  On the second sheet, the red circled area is actually
a drainage ditch instead of a roadway.  Could you incorporate these items into your comments back to me?  Also, I believe that you were going to add some additional items that were a
result of the meeting.  If you could incorporate these changes, I will get them sent to John Hill for review.

 

Thanks,

Clay Barnett, P.E.

Clay,

 

For your review; we have not shared these with PK.
