SUPPLEMENTAL STATEMENT

(by J.

D.

Dumeile):

While

I agree with the result

in this case and with the

conditions of the order

I do have a somewhat different emphasis.

I think that the record did demonstrate a reduction in

storm water to

the

54” combined sewer.

At a 1.3 inches per

hour rain about 186,000 gallons an hour would he diverted

from that sewer.

The basement of a home 30

ft. by

20 ft.

in size will hold about 9,000 gallons at a depth of

2

ft.

Thus the 186,000 gallons in one hour,

if not diverted, would

flood

20 homes to about a

2 ft.

depth

in their basements.

If the rain continues then more homes or deeper depths of

flooding would result or both.

Since the proposed development would improve the environ-

mental

situation the usual hardship tests do not apply.

Flooding will lessen in both frequency

and

in

depth,

I believe.

The

“down side”

is more

human

waste.

But

this

waste

is diluted

many times by the rain,

And

the

prime hazards

in basement

flooding are electrocution and property damage

(paneling,

etc.)

which both are dependent on water depth.

Waterborne disease

is not as serious a hazard as

is that of electrocution in base-

ment flooding.

This record was deficient,

The McClure Report was not

entered into it and would have been helpful.

The Village of

Lombard indicated that

it had no copies of this important

1980 report.

An intervenor

had

a copy but did not enter

it.

The McClure Report,

if

entered,

might

have

answered

Board

Member

Forcade’s concerns and saved a dissent.

Lastly,

the reasons for restricting flow to the Grove

Avenue storm sewer were not made clear.

A storm sewer should

handle storms

and ordinarily does not have detention facilities

57-191

upstream.

What happens

to flow to that storm sewer?

Does

it

surcharge manholes and cause

surface flooding?

Does

it surcharge

and reach inlets

to the combined sewer?

Because of the record deficiencies enumerated above

the

conditions added

to the order were necessary.
