OFFICIAL.

The Honorable ClCy CouHSL,
of Alexandria Va,
Gentlemen:--
For your information I submit the
following: In recent years we nave
repaved about fifty squares in
manner satisfactory to The property
owners and meeting the require
merit, of modern traffic. The larger
portion Of this work is of high
class Of paving on concrete bass:and
costing from $3.50 to @2.lo per
square yard.
Il looks. however, as if the demand
for smooth roadways is far eX-
reedinr our financial ability to con-
tinue as q policy the laying OF TINS
high class pavement, ana that moss
careful consideration should be CIV
en- 10 make what money we have Tor
repairing extend over greater area
This can be done only by reducing
the roadway area, or adopting class
cf roadway paving of less first cost
or both. ~
The development of broken stone
roadway. with an asphalt or coal
or flIer commonly called bitumln-
us McAdarl, or bltuminous concrete:
has reached stage that seems &c
insure conditions : of reasonable
chcapness ard lasting qualities Tor
medium class traffic especially "hen
laid on a concrete base. Under Or
dinarv conditions: this pavement
should be laid for about sl.lO PEI
SQUARE yard.
With the above idea in view, ana
for your honorable consideration IN
deciding the class Of paving to be
used on various strees, J. SUBMIT 'he
following comparisons Of cost. :,
In these statements &c s assumed
tbat granite curb and 2 IL 1T. vitri-
fed brick gut;ers and concrete Dase
arc used on bcI.h CLASSES OF paving
and both widths Of streets, ana are
considered permanent, or that repairs
r. curb and cutters would be tne
same on both widths of streets. Also
that the average frs: cost OF hlgh-
or class roadways, is Sl.9u per square
ward and that the average !lrst eoss
Of lower class roadways IS Div pr
square yards; that sum saved "ouio
hear Az per ent.compond interest
semi-annually; that no credit is CIV,
removed, and that inc, saving IN IN.
sweeping a 27-foot roadway, IS sl6
per annum, which would also Deai
4 IL per cent. compound interest,"
and that the cheaper ciais OF Ioao
viii require no repairs the firSt three
Years and rhat the comparisons are
between the total costs. o1
would also state that the genera
onin;on seems to be that the Dllu,
n,;nous movements can be resur1aceo
nmnnallv for from four to hve
cents per square YARD.
