Why
Is
Accessibility
Important? 


Why
Is
Accessibility
Important?


• Under
the
ADA,
a
person
with
a
disability
is
a
person
who:



‐Has
a
physical
or
mental
impairment
that
substantially
limits
one
or

 

more
major
life
activities.
 
‐Has
a
record
of
such
an
impairment.
 
‐Is
regarded
as
having
such
an
impairment.



Why
Is
Accessibility
Important?


• 1
in
5
Americans
have
a
disability

• The
disability
population
is
growing
due
to
aging,
war,
and


identification.


• The
disabled
population
is
the
largest
minority
group
in
our
country.


Why
Is
Accessibility
Important?


• Accessibility
does
not
always
only
benefit
wheelchair
users.

Accessible
Ramps,
Slopes
and
Cross
Slopes
 
‐The
slope
of
a
ramp
is
important
for
a
person
in
a
wheelchair
going
 both
up
and
down
the
ramp.

 
‐Too
steep
of
a
slope
going
down
the
ramp
could
result
in
a
wheelchair
 user
losing
control.
This
could
lead
to
an
uncontrolled
descent.

 
‐Too
steep
of
a
slope
going
up
the
ramp
could
limit
wheelchair
users
 from
even
using
the
route.
Many
people
with
mobility
disabilities
have
 limited
strength
to
overcome
changes
in
elevation.

 
‐Users
with
or
without
disabilities
benefit
from
having
ramps
that
 comply
with
the
accessibility
standards,
including
bicycle
riders
and
 parents
pushing
baby
strollers.

 ‐The
steepness
of
a
ramp
will
either
encourage
or
discourage
use
of
a
 route.

‐Landings
are
important
because
they
provide
rest
between
ramp
 segments
and
they
provide
an
opportunity
to
turn
around.

 
‐Rest
and
turn
around
space
is
beneficial
for
all
users,
not
just
users
in
 wheelchairs.

‐No

‐Concrete

and

of

have

 

changes
in

greater
than

‐Wheelchair

are

‐Changes

can
be
tripping
hazards
for
fully
mobile
users
of

 

the
ramp.
