The CWPPRA Legislation
The Coastal Wetlands Planning, Protection and Restoration Act, (CWPPRA pronounced
kwǐp-rŭh), is federal legislation enacted in 1990 that is designed to identify, prepare,
and fund construction of coastal wetlands restoration projects. Since its inception,
151 coastal restoration or protection projects have been authorized, benefiting over
110,000 acres in Louisiana. The legislation (Public Law 101-646, Title III CWPPRA)
was approved by the U.S. Congress and signed into law by former President George
H. W. Bush.
The annual budget for CWPPRA funded restoration has varied through the nearly twenty-year life span of the Act. The budget has ranged between approximately $30 million
per year to nearly $80 million per year. The funded Louisiana projects provide for
the long-term conservation of wetlands and dependent fish and wildlife populations
with cost-effective plans for creating, restoring, protecting, or enhancing coastal
CWPPRA Restoration Techniques
CWPPRA project managers, scientists, and engineers use a variety of techniques to
protect, enhance, or restore wetlands. Each restoration project may use one or more
techniques to repair delicate wetlands. These techniques include:
- marsh creation and restoration
- shoreline protection
- hydrologic restoration
- beneficial use of dredged material
- sediment trapping
- vegetative planting
- barrier island restoration
- bank stabilization
Below is an example of the restoration technique known as the beneficial use of
dredged material: CWPPRA Project BA-39 Mississippi River Sediment Delivery – Bayou
Sediment is used from the Mississippi River to rebuild wetlands in a new location.
The red boat near the levee is pumping sediment to the fragile wetlands in top left

water, creating new wetlands.
The sediment from the river is delivered from the river to then newly created marshlands.

Why Protect Louisiana
Louisiana wetlands are unique and vital ecological assets worth saving. Wetlands
act as a storm buffer against hurricanes and storms. They act as flood control devices:
holding excess floodwaters during high rainfall (much like a sponge). Wetlands replenish
aquifers, and they purify water by filtering out pollutants and absorbing nutrients.
CWPPRA funds have been instrumental in helping to restore Louisiana’s vanishing
Approximately 40 percent of the coastal wetlands of the lower forty-eight states
are located in Louisiana. Unfortunately, this fragile environment is disappearing
at an alarming rate. Louisiana has lost up to 40 square miles of marsh per year
for several decades – that’s 80 percent of the nation’s annual coastal wetland loss.
To date, Louisiana has already lost coastal land area equal to the size of the state
of Delaware. This loss is at an average rate of an acre every 38 minutes. If the
current rate of loss is not slowed by the year 2040, an additional 800,000 acres
of wetlands will disappear, and the Louisiana shoreline will advance inland as much
as 33 miles in some areas.
Wetlands also provide habitat for a variety of wildlife. Coastal Louisiana lands
are the breeding grounds and nurseries for thousands of species of aquatic life,
land animals, and birds of all kinds – including our national symbol, the bald eagle.
This ecosystem also provides a migratory habitat for over five million waterfowl

People also benefit from Louisiana’s coastal lands. Louisiana is responsible for
a major part of our nation’s oil and gas production, shipping commerce, fisheries
industry, fur harvesting, and oyster production, accounting for over 55,000 jobs
and billions of dollars in revenues. Additionally, wetlands are wonderful recreational
resources and are part of Louisiana’s growing ecotourism business. To learn more
about the economic value of our wetlands, read “The Cost of Doing Nothing” in WaterMarks (Summer 1999).

Although current funding levels do not support all of the necessary restoration
required for a sustainable ecosystem, CWPPRA continues to address immediate restoration
needs while establishing a foundation of strong science, public participation, and
agency cooperation that will continue to serve as the cornerstone of future programs.
