"A IS~LOOI STREET. CuTD TO ID
| ample for a heavy business street.
A 32-foot street. curb to curb, I'M
INSTRUCTED by street railway tracks,
is ample for a great retail bushes
district.
A 36-foet street, curb to curb, of the
highest class construction, is ample for
| all the demands that can be made or
it as a boulevard, except when located
| in some great metropolis.
AIR SPACE AND LANDSCAPE
EFFECT.
These desirable and imperative char
acteristics can be best obtained by
combining the highest grade of streets
of utility widths with
1st. Very wide sidewalks; or
End. A combination of sidewalks and
grass strips or street lawns; or
| 3rd. A combination of the above and
fixed building line limits, as shown
| in sketch No. 4.
| Tt has been said municipal govern
ment cannot fix building limit that
will legally force compliance in the
case of residences.
am confident the report Of the Gem
mittee on the Reclamation of the
Waikiki District will demonstrate this
restriction can be enacted and enforced.
STREETS OF MACADAM.
Tt is generally admitted that a good
street of this material must be macad-
amized to the depth of at least ten
inches.
That it's surface becomes, within six
to twelve months, irregular and re-
quires renewal of top dressing.
That scarce three years pass before
the macadam must be loosened, added
| to, redressed and rolled.
That the macadam is crowded away
| from the manholes and that the cross
| ings nut be so raised as to cause,
| with other obstacles, a series of dis
agreeable jolting.
| CRETE AND BITUMEN STREETS
CONSTRUCTION.
First. The base soil or earth of the
street should be compact, as compact
as nature and heavy rolling can make
| it. 1t should be graded SO as to be
suitably crowned.
Second. Upon this should be laid
| five or six inches of concrete of a con-
sistency of 1 to to 5, reinforced by
corrugated ga inch bars, laid cross
wise the street, its full width and six
| feet apart. Embedded in the concrete,
covering the entire street, should Be a
| layer of expanded metal. The CORFU
gated bars and expanded metal should
be laid close together. This construc-
ton binds the entire bed of the street
| together.
Third. This bed of concrete may butt
against rock curbing on either side, or
| a reinforced curbing of concrete may
be made and become a part of the
| roadway.
TOP FINISH.
| This should be of bitumen of a suit
| able thickness for the traffic to pass
over it. The consistency or hardness
/ of the bitumen should be regulated to
| the character of the vehicles and mo-
tive power.
SAFE LOAD ON REINFORCED
CONCRETE BASE. -SPECIFICA-
TIONS AS ABOVE.
| The nominal maximum load is above
| SIS pounds per square inch.
The safe load is not less than 120
/ pounds per square inch.
| No such load is likely to be ever
| placed on such a street.
ECONOMIES OF THIS CONsTRUC-
| TION.
! A perfect surface that can handle
more traffi, with less traction exerted
than any other street yet constructed.
| Streets of moderate and perfectly
utilized width.
The doing away with specially con-
structed street crossings and their ir-
| regularity.
| The streets can be easily swept by
human or mechanical means, and, If
desired, can be cleaned by flushing
with water. The surface cannot be
| scraped off.
| Finally, an almost indestructible
street. it's flaws and wear easily re-
paired.
