My engineers m that the cost OF
increasing the reservoirs capacity at the
Banta site will exceed the same cost at
the Kingland site, about $4,000, based on
prices of today.
This increased cost at the dam and res

NY engineers will be pleased to submit
for your inspection and verlhcation, the
data as to the elevation, areas and guam

made are based.
The elevations herein mentioned are
based upon the differences between the
base of the State Goodetic survey and the
official Jersey City base as determined by
adjacent bench marks in Jersey. City.
Careful levels now being run from tide
water to Boonton may change the hgures
to the extent of two or three inches, but
not the absolute heights.
