Attention: Graham Foster
Reference: Maloney Road/Box Culvert
Dear Graham:
As instructed at the last Town Board meeting, I have analyzed the drainage
area tributary to the existing culvert on Maloney Road just west of Daley
Road that has recently experiencing failure. A field inspection with you
has confirmed this impending failure.
The existing culvert is approximately a 44" x 74" coated corrugated metal
pipe. The date that the existing culvert was installed is unknown at this
point, but is failing along the mid-point of the pipe to the extent that the
roadway runs the risk of being impassable. The existing culvert has a
cross-sectional area of 1 8 square feet.
I have analyzed the drainage area tributary to this culvert and find it to be
in the neighborhood of 1,400 acres. For a 25 year storm this would
dictate the installation of a culvert with a significant area, probably in the
neighborhood of 80 - 100 square feet.
In a subsequent field inspection, we looked at the culverts just north of
this area on Daley Road, and the railroad culvert further north. The
existing culvert on Daley Road is a rectangular box culvert with a cross-
sectional area of approximately 40 square feet. The railroad culvert north
of this has an approximate area of about 14 square feet.
I would then recommend that you install an aluminum box culvert with a
cross section area of between 30 - 50 square feet. To that end, I have
sent you a copy of the Contech aluminum box culvert pricing and sizing
sheet.

Another alternative would be to install dual, 10-gage aluminized, Type 2,
corrugated metal pipe with the size approximately between 30-40 sq. ft.
A dual 47" x 71" pipe will have an area of approximately 36 square feet.
As you can see from the sheet, it will cost significantly less than the
aluminum box culvert.
It would appear, and as verified by our discussion, that this would be the
way to go.
It also has become evident that a permit will be needed from the New York
State Department of Environmental Conservation for this project. We are
proceeding with that application presently.
If there are any Questions, please do not hesitate to contact this office.
Very truly yours,
