Linking Land Use to Coastal Water Quality

• Coastal GA NEMO is an educational program that
  provides information for land use decision makers
  addressing the relationship between land use and
  natural resource protection.

3
NEMO History

• 1991 Developed at University of Connecticut
• Sea Grant
• Cooperative Extension
• Connecticut Natural Resources Department
• 2000 National Network established
• Coastal GA joined National Network
• 2006 32 NEMO programs

4
The National NEMO Network
A group of educational programs focused on the
relationship of land use to natural resource
protection, sharing information, materials and
educational models.

The NEMO Philosophy

• EDUCATION is the method
• LOCAL LAND USE DECISION MAKERS are the target
  audience
• The IMPACT OF LAND USE on water resources is the
  issue
• NATURAL RESOURCE BASED PLANNING is the solution
  offered
• GEOSPATIAL TECHNOLOGY is used to enhance the
  education

The Issue How Land Use Impacts Water Resources
Linking Land Use to Coastal Water Quality

• Increasing Population
• Coastal GA
• ? 62 1970-2000
• Camden County
• ? 43 2000-2015
• Increasing land consumption density
• Development in undisturbed areas
• Overloading or destruction of natural ecological
  systems
• Loss of Green Infrastructure

Green Infrastructure

• Georgia has 1/3 of the remaining salt marsh on
  the Atlantic coast
• One Acre Marsh 14,000/year
• 5,600,000,000/year
• Center for a Sustainable Coast

The Issue How Land Use Impacts Water Resources
The Old Era of Water Pollution
12
Polluted Runoff is the 1 Water Quality Problem
in the U.S.
Every 8 months, nearly 11 million gallons of oil
run off our streets and driveways into our waters
the equivalent of the Exxon Valdez oil spill

• US EPA
• Pew Oceans Commission Report

13
What is NonPoint Source Pollution? (NPS)
NPS occurs when water washing over the land picks
up contaminants and carries them into waterways,
either directly or through storm drain collection
systems.

Development Impacts on the Water Cycle

Impervious Surfaces

• Materials like cement, asphalt, roofing, and
  compacted soil that prevent percolation of runoff
  into the ground.

• Indicate intensive land uses that cause pollution
• Inhibit recharge of groundwater
• Prevent natural processing of pollutants in soil
  plants
• Provide a surface for accumulation of pollutants
• Provide an express route for pollutants to
  waterways

Imperviousness varies by use
0 5 Natural
0 15 Rural
5 - 65 Suburban
50 - 95 Urban

The NEMO Solution

• Prevent NPS through improved planning
• Minimize impacts with integrated site design
• Mitigate impacts through stewardship and Best
  Management Practices

21
The NEMO Solution

• Prevent the Problem

Catalyze Empower Local Land Use Decision Makers
to

• Ask the right questions
• Put development in a greater context
• Get started on natural resources based planning

22
The NEMO Solution

• Minimize Mitigate Impacts

Encourage integrated stormwater management
