“Wise water management for a safer and stronger New Orleans”

We are a group made up of organizations who strive to

educate individuals about wise water management for a

safer and stronger New Orleans.

Water Wise NOLA

1) Neighborhood Water Wise

Workshops: Introduce green infrastructure and how

to incorporate it on your lot.

• Lower 9th Ward: April 2015

• Gentilly: May 2015

• Algiers: June 2015

• Mid City: July 2015

3) Professional Development: Online training to provide professional

development for stormwater

management.

2) Capacity Training: Build capacity in neighborhoods to

address rainwater management.

New Orleans receives 63 inches of rainfall on average per year

making it the second wettest metropolitan in the USA.

Flooding

Flooding due to rainfall will cost Greater New Orleans $8 billion

dollars over the next 50 years.

Grey Infrastructure: pipes, canals, pumping stations,

water treatment plants, etc

The S&WB of New Orleans currently accomplishes draining 63,000 acres by utilizing 90

miles of covered canals and more than 80 miles of open canals to convey storm water

runoff to 21 drainage pumping stations.

Green Infrastructure: Green Infrastructure is the use of

plants and trees to manage rainwater and reduce

flooding.

How it Works

Green Infrastructure:

Why it is important

Green Infrastructure and low impact development allows individuals to actively

participate in small scale flood protection through a distributed approach to

managing water. When water is slowed down, held temporarily, and directed

into the soil (infiltrated), it can provide direct benefits on the property.

This approach also reduces the amount of stormwater trying to enter into the

city’s system of pipes until after the peak rains have passed, which reduces the

frequency of street flooding during small scale storm events and also improves

water quality in Lake Pontchartrain and other surrounding water bodies.

Green infrastructure is another tool for flood protection.

Living with Water

Assessing your property

Begin with a sketch showing a general

outline of the property, structures and

other hard surfaces

Locate points where rainwater is

concentrated, such as downspouts and

pipes through curbs or walls, and where

it runs off hard surfaces.

Managing Rainwater on Your Lot

Identify where water can be intercepted

(what opportunities exist to manage on-site)
