Attached are your mark-ups and two sets of revised plans. We have made all revisions per
your letter of May 19 except for the fonowing:
Comment No. 3 - We do not think these inlets present a problem and prefer to
leave them where they are.
Comment No. 5 - We have calculated a hydraulic elevation in these inlets
including an inlet loss and find the elevation to be 506.86. This compares to a
top-of-curb of 507.61.
CQmment No. 6 - Positive overflow is achieved via Round Rock Drive to Harris
Street. Note that the highest gutter grade is well below any finished floor
elevation.
If you have any questions, please let me know.
