would deprive the applicant of the reasonable use
of his land; and
That the variance is necessary for the r-eservation

the applicant; and

detrimental to the public health, safety, or
welfare, or injurious to other property in the

other land in the area in accordance with the pro-
visions of these regulations. Such findings of the

which such findings are based, shall be incor-
porated into the official minutes of the council
meeting at which such variance is granted.

Method of Calculation of Run -Off - Storm water run-
off shall be computed by the Rational Method which
is an analysis of the run-off problem for each
drainage area along rational lines and includes the
analysis of the flow of storm water from the sur-
face on which it falls to the inlet that leads to
the storm sewer and then through the storm sewer,
culvert, and/or channel to the point of disposal.
The formula for calculation of run-off by the
rational method is Q = CIA.
Q = the maximum rate of run-off discharge
expressed as cubic feet per second.
C = a run-off coefficient which varies with
the topography land use and moisture content
of the soil. The run-off coefficient shall be
based on the ultimate use of the land as
recommended by the master plan for the city
and shall be selected from below

Streets and underground storm drains shall be
designed to accommodate a five (5) year frequency
storm with adequate overland relief for the twenty-
five (25) year storm. Design of all bridges, cul-
verts, underpasses and open channels are to be
based on a twenty-five (25) year frequency;
The five-year storm run-off may be carried in the
streets at a depth up to the curb height, that is
to the full capacity of the street;
When the five-year storm run-off exceeds the street
capacity then storm drains must be added;
When there is no overland relief for a 25 -year
storm, then the combined street and storm sewer
capacity must be adequate to accommodate the
25 -year storm;
Where the storm sewer leaves the street right-of-
way, if there is not an overland Swale, then the
storm sewer must be enlarged to a 25 -year storm
design capacity;
Sufficient and adequate inlets are to be installed
to allow entry of required quantity of water into
storm sewers. Inlet openings shall be about seven
inches (7") high. openings shall be as determined
on the basis of one (I) linear foot of inlet per
cubic foot per second of storm water to be picked
up except at the jag of a street where emergency
overflow is provided, 1.5 cubic foot per second per
foot of inlet opening will be allowed;
