lot shall be considered the front of such lot, and in cases
where the two sides are equal, the Mayor and Common Council
of Riverdale shall determine which is the front and which is
the side of such lot, and such determination shall be final and
conclusive; and provided, that in cases of lots abutting on
more than two streets, and of lots of irregular or unusual
shape, and in cases of lots abutting on two or more streets
where in one or more of such streets, roadbeds, sidewalks,
curbs, gutter and street improvements, or any or all, have
been, or are about to be, constructed under such circumstances
as not to subject such lots to a special assessment by the
Mayor and Common Council of Riverdale, the Mayor and Com-
mon Council of Riverdale shall have full power and authority
to adjust assessments to be made against such lots for the
cost of improvements herein authorized abutting such lots to
such an amount as shall be just and equitable, and the cost of
improvements thus exempted shall be included in the assess-
ments to be made against the abutting property included in
the project, and such adjustments as may be made by the
Mayor and Common Council of Riverdale shall be final and
conclusive.

In any case in which the Mayor and Common Council of
Riverdale are authorized to assess the cost of the construc-
tion of street Improvements consisting of roadbeds, sidewalks,
curbs, gutters, or any or all of them, against the abutting land
and such an improvement results in an excessive cost on ac-
count of unusual excavation or unusual fill, or the construc-
tion of a drain, culvert, or bridge, at an expense entirely out
of proportion to the improvements being constructed, the
Mayor and Common Council of Riverdale may, in its dis-
cretion, exclude from the total cost of such improvements to
be assessed upon abutting land the cost, or any portion there-
of, of such excavation, fill, drain, culvert, or bridge, and to
pay the amount of the costs so excluded out of any fund prop-
erly chargeable with such an expense; and the ten-year pay-
ment plan provided by Chapter 50 of the Acts of the General
Assembly of Maryland of 1933 (special session) shall extend
to and be accorded the Mayor and Common Council of River-
dale in such regard in the same manner as any other property
owner paying assessments hereunder. The determination of
the Mayor and Common Council as to the assessments against
abutting land and the proportion to be paid out of other funds
in any such case shall be final and conclusive.

The Mayor and Common Council of Riverdale are hereby
authorized, in their discretion, whenever petitioned therefor
by the owners of more than 50 per cent of the land abutting
on any street, or part thereof proposed to be improved, for
the construction of sidewalks, curbs, gutters and roadbeds, or
