Riparian Areas
Land along the banks of a
river, lake or other body of water is known as a “riparian” area. The riparian area is a transition from
aquatic habitat to terrestrial habitat, and as such is often very ecologically
sensitive. Small changes can have a
huge impact both on the plants and animals that live on the banks of the water
body, and on the aquatic habitat itself.
60% of B.C.’s species use riparian habitat in whole or in part.
Development in riparian areas
can have impacts that might not be obvious.
For example, removing vegetation from the banks of a stream can cause
the stream to become muddied and the bank to become unstable without the
support of plant roots. In addition,
the loss of shelter and shade can increase the temperature of the stream,
killing fish or resulting in toxic algae blooms.
Provincial Responsibility for Riparian
Protection
The constitutional
responsibility for managing riparian areas lies primarily with the provincial
government. The federal government does
have a role, through the Fisheries Act, when
development in a riparian area directly impacts on fish habitat. However, with this notable exception, the
riparian environment is protected by provincial legislation and planning
processes.
The provincial government has
created a number of legal tools to protect riparian areas.
The Province’s Water Act is primarily concerned with allocation of
water. However, it does contain one
very powerful tool for protecting riparian areas. Section 9 of the Act provides that any person making a “change in
or about a stream” must either:
·
Have a water licence under the Water Act
authorizing the change;
·
Have received written government approval before making
the change; or
·
Be acting under regulations created under the Water
Act.
Changes “in or about a stream”
includes any significant modifications within the banks of any watercourse
(whether it has water in it at the time or not). Through the Water Act government officials can impose conditions
setting out exactly how any “changes” must be made, or refuse to allow changes
at all.
Three other acts are of minor
importance in regulating certain types of changes in or about streams. The Drainage, Ditch
and Dike Act and the Dike Maintenance Act regulate the construction and
maintenance of artificial anti-flooding measures. The River Protection Act
authorizes the Minister of Transportation to take action to stabilize river
banks in danger from erosion.
Other legislation deals with
riparian protection in the context of different industries. For example, the Forest and Range
Practices Act [link to O14-2] requires that a strip of trees be left
alongside certain classes of streams when logging occurs on public lands. Read the Guide pages concerning the industry
that you are concerned about for more information on industry-specific measures
for riparian protection.
This page of the Guide
concentrates on actions that alter the riparian area itself. For information on actions which pollute or
alter the river itself, as opposed to the banks, see the page on rivers, streams and lakes.
Local Government
The Fish
Protection Act gives the provincial cabinet the power to create “directives” for streamside protection. Local governments must then pass by-laws
implementing the directive or providing equivalent or better protection for
riparian areas. The province currently
has a Streamside Protection Regulation under which local governments will have
to pass by-laws requiring that development be set back a specific distance from
streams by 2006 at the latest.
Although local governments are
not yet required to have such by-laws in place, many local governments have
created requirements around set-backs and/or designated streamsides as
environmentally sensitive. The tools
available to local governments to protect streamsides are found in the Local Government Act.
Common Law and Riparian Rights
Under the judge-made common law the owner of riparian land had rights of
access and use of water from the stream or lake that the property
bordered. The right to use water from a
river has been limited or eliminated in B.C. under the Water
Act. However, downstream
riparian owners probably continue to have riparian
rights against flooding or against pollution caused by upstream changes
to riparian areas.
