GIWW – Perry Ridge West Bank Stabilization (CS-30)

Settlement plates such as the one pictured here will be used to determine if settling of the structure has occurred. Technicians from NRCS’s Crowley Watershed Office are shown taking baseline elevations before more rock is deposited. Future elevation readings will be taken after the structure is completed.

Location

The project is located along the northern bank of the Gulf Intracoastal Waterway (GIWW) between Perry Ridge and the Sabine River in Calcasieu Parish, Louisiana.

Problems

This section of the GIWW was dredged to allow the use of doublewide barges, and,  consequently, has intensified the occurrence of wake erosion. In addition, the construction of the Calcasieu Ship Channel and the deepening of Sabine Pass have increased the salinity and water currents within the GIWW. These activities have caused the GIWW shoreline to breach, thus impacting the interior marsh of the project area.

Restoration Strategy

Proposed project components involve installation of 9,500 feet of rock riprap along the northern bank of the GIWW from Perry Ridge to its intersection with the Sabine River.
An additional 2,200 feet of rock riprap will be installed from the Sabine/GIWW intersection north along the Sabine River. This proposed work is referred to as “construction unit number 2.” Approximately 22,952 linear feet of terraces will
be constructed in the shallow, open water areas north of the GIWW to reduce fetch (distance a wave can travel) and allow recovery of the interior marshes. Terraces will be
vegetated with 9,400 trade-gallon-sized plantings of California bulrush. This proposed work is referred to as “construction unit number 3.”

Progress to Date

Project construction is complete. The monitoring plan is currently in development and should be finalized in the spring of 2002.

The project is on Priority Project List (PPL) 9.

Project Area: 1,132 acres
Approved Funds: $2.19 M
Total Est. Cost: $2.20 M
Net Benefit After 20 Years: 83 acres
Status: Completed

A Coastal Visit From St. Nicholas

Please enjoy this CWPPRA Parody of Moore’s holiday classic “A Visit From St. Nicholas,” more widely recognized as “The Night Before Christmas.”

 

‘Tis the day we call Christmas and all through the marsh,

The conditions are getting unusually harsh.

Their flowers are wilting, the shrubs getting bare

In response to the cold and dry air that is there.

 

Losing some green as the maples turn red,

Creatures prepare for hard times just ahead.

Drakes coming south, [1] with their females so drab,

Their sexes dimorphic, just like a blue crab.

 

Unlike the crab, though, get out of the water;

The crabs get to rest until it gets hotter.

They bury themselves in the mud and the mash, [2]

Unfortunate ones have to bury in trash! (Please don’t litter.)

 

Our coast doesn’t freeze much but this year might go

To 32 Fahrenheit, maybe below.

Some creatures go far, but some must stay near,

Plants and their roots are anchored right here.

 

Cold can be dangerous, plants can get sick,

Mangroves don’t have a cold-weather trick.

They deal with the salt and they deal with the rain,

But mangroves fear cold, so South they remain. [3]

 

The Turtles, the gators, the lizards, the snakes,

All have cold blood, and so they brumate. [4]

So, hang all your wreaths and deck all the halls,

But think of the wildlife, no matter how small.

 

Habitat loss can hurt plants just as well,

Even those plants that are one simple cell.

Some plants can float and some plants can grow stalks;

yet to be found is a plant that can walk.

 

But wait! We humans have legs we can use

To move plants to places, like in Calcasieu.

Pontchartrain, Breton Sound, Atchafalaya,

These wetland basins now cook jambalaya.

 

We love our heritage and love spicy food;

we also love science that’s been peer-reviewed.

The Delta gets sediment and it slowly grows,

But what of the rest that sits under our nose?

 

Let’s restore our coast, let’s give it a try,

Think about those who can swim, walk, or fly.

Those who are sessile, of course, matter too.

CWPPRA loves wetlands, alive through and through.

 

Our work is important, it always gets better,

sometimes with projects that work well together.

Funding the coastline is not just a show,

It helps our plants and our wildlife grow.

 

Other good things that come from restoring

Are seafood, and commerce, and outdoor exploring.

We protect ports and some habitat too,

We protect cities and we protect you.

 

Enough of the bragging, there’s still more to learn

On techniques we use to reduce the concern!

We nourish beaches to give seabirds refuge

And rebuild salt marsh for protection from deluge.

 

Working away, we burn midnight’s oil

To stop salt intrusion and relocate soils.

We plan with our partners to restore the most

For CWPPRA to work on Protecting Our Coast.
