Total. ............................ 716, 800
wThis estimate is somewhat In excess OF So.
100000, but the Board OF Engineers give their
estimate at about ~, ,5o0, 900. Tho cost can bo
sections ! and 2, at one foot above the freshet
slope of 1877, instead OF three feet, rs tho
Board OF Engineers recommended. Tho esti.
mated cost can bo reduced to S2,621,O5
by liking the grade above Long Bridge at two
foot above the froshot slope OF 1877, and
instead OF vertical wall FOR the exterior ro.
Tho saving, In either case however, would
not, In my opinion, compensate for Its dis.
advantages.
''The price, 1s cents per cubic yard for
dredging and depositing the material, is con.
sidered low. IL is hardly to DO expected that
the work can be done at a lower 4 gure, unless
n contract could be made for at least one.half
OF the entire work Mt ono time.
"There are several other matters intimately
connected with tho project OF reclaiming tho
flats, but their cost is not included in this es.
Innate.
"These are the disposition OF tho sewerage
that now discharges Into the Washington chan
mel, retaining walls for tho B.street sower-
canal and the rebuilding OF the Long Bridge
with wider spans that Will offer less obstruc.
tion TO the flow OF water.
"Tho amount appropriated by act passed
August 2, 1882, for carrying this improvement
into effect is 100000, and recommend that
1t be applied to that end in tho following
'Apply 100000 to dredging n channel
twenty feet deep at low tide and as wldo as 1t
deep water near Giesboro' Point to Georgetown.
ut is estimated that channel twenty feet
deep and four hundred feet wide can be made
such channel will measure about 100000
cubic yards, about two.thirds OF which should
come from the portion above Long Bridge
and the other third from the bar near Giesboro'
Point. That portion taken from the channel
above Long Bridge should be deposited In sec-
tion 1. That excavated below Long Bridge
should be deposited In section 8, as tho towage
GrteaDOrO' 1
add considerably to tho last. Seventy thou
sand dollars should bo allotted to tho
ways referred to In the project for nlllng tho
lakes In section 1 and purifying tho water
in the Washington channel. The estimated
Major Twining, was $40, 600 Tor ono and s3O,.
600 for the other. Detailed estimated for
them can only be given after careful study
as 1t is inexpedient to begin their construc,
tion before spring, there Is ample time for this
purpose. The remaining $4,000 should be
allotted to contingencies, office expenses etc.
"1n some respects II would bo advantageous
to concentrate the dredging operations to that
portion OF tho river about Long Bridge, leav
Ing section for later period OF operations,
but 1t is desirable to open a channel all the
way TO Giesboro Point. A finished section Of
the channel above Long Bridge would be more
likely TO I'LL up with sediment brought down
the river In time OF frcshets, If the bar below
the bridge remained intact, than n narrow
channel Of the full length. The project hero
submitted VIII not In any, way prevent mOdin-
cations being made should they become, after
more careful study OF the subject, either ad-
vantageous or expedient.
"Thc Work TO be Pushed.
"There is no reason In my mind why the
work Of dreding and filling may not be car
ried on with advantage during the greater
part OF the winter. further suggest that the
work can be done more advantageously by
contract after due advertisement of proposals,
In accordance with the laws and regulations
on the subject, and commend that 1t be done
in that manner.
81 submit with this project map showing
the proposed plan of improvement, In accord.
ance with the act of August 2, 1882.
"Very respectfully, your obedient servant,
