Dear Basil:

We have surveyed the as constructed elevations of the detention pond, outlet ditch and
street drain pan at the Cobblestone Comers development. The as built elevations are shown in
red on the attached print.
Also, we surveyed the swales between buildings and found that additional grading must be
done to provide adequate drainage. The existing elevations of the swales are shown in green on
the attached plan. I met at the site with Mr. Ed Seier and his grading contractor on February 9,
1995, and they are now doing the additional grading.
Mr. Seier has a closing scheduled for February 10, 1995 on Lot 24 and would like the
C.O. released on Lot 24. This seems a reasonable request as he is going ahead with the necessary
grading.
The detention pond volume as constructed is adequate, and he has graded the outlet ditch
along Shields to the requirement of the Engineering Inspector.
I will provide additional red lines when the swale grading is completed.
Sincerely,
Phillip I. Robinson, P.E. & L.S.
Vice President J
