. Tax adjustments.

When used as parts of a comprehen-
sive program, these measures can reduce
many of the adverse effects of develop-
ment on most floodplains to a con-
siderable extent. However, some
developments detrimental to the natural
values of floodplains are likely to
take place in spite of such a program
because of developments requiring a
ri verfront or seafront location, or
those which derive a particular benefit
from such a site for some other reason.
In those cases, the detrimental effects
of the permitted developments can be
minimized by such things as:

. Prohibiting land fills, septic tanks,
dumping or storing pathogenic or
toxic substances, and the introduc-
tion of plant and animal species not
common to the area which would upset
the natural ecological balance.

. Preserving natural contours
age patterns and
historical cultural sites.

. Minimizing tree cutting and other
removal of vegetation, erosion,
runoff of nutrients, disruption of
wildlife habitat and other ecologi-
cally sensltlve areas, heavy construc-
tion, and alterations in stream flow.

. Discouraging use of
dredges, weeders and
harvesting equipment.

Restoring Diminished Values

Restoration involves reversing
the degradation of the floodplain
caused by residential, industrial and
commercial development or intensive
agriculture, forestry, and other activi-

ties. The primary approaches for
reestablishing a natural setting on the
floodplain are removing harmful exist-
ing developments, minimizing the impact
of developments that remain, and
accelerating natural recovery from
disturbances.

Relocating or removing existing
waterfront developments may be feasible
if only a small number of structures
are involved and the nature of their
use does not make such a location
essential. If so, relocation of the
structures and their contents, or
relocation of the contents and demoli-
tion of the structure, may warrant
consideration. Even if a coastal or
riverfront location is essential, it
may be possible to relocate isolated
activities and structures to an already
developed part of the waterfront, or
group them so that the largest possible
expanse of natural floodplain is left
untouched.

Fish stocking accelerates
recovery and helps restore
floodplain values.

Removing existing developments is
usually impractical where significant
numbers of structures are involved. It
may also be impractical for other
reasons, such as the size or design of
a structure or because of a large
investment in fixed facilities. Reloca-
tion of agriculture, lumbering or
mining is also not usually practical.
For these activities, action should be
