Plants adapted to grow in wet soils.
What tool provides approximate wetland locations?
NJ GeoWeb.
Who officially delineates wetlands?

What are the three wetland resource classifications?
Ordinary, Intermediate, and Exceptional.
What is an Ordinary Resource Value wetland?
A small isolated wetland, drainage ditch, swale, or human-made detention basin.
What is an Intermediate Resource Value wetland?
Any wetland that is neither Ordinary nor Exceptional.
What is an Exceptional Resource Value wetland?
A wetland connected to FW1/FW2 trout waters or threatened/endangered species habitat.
What is the transition area for Ordinary wetlands?
0 feet.
What is the transition area for Intermediate wetlands?
50 feet.
What is the transition area for Exceptional wetlands?
150 feet.
What is a transition area?
A protective buffer between uplands and wetlands.
Why are transition areas important?
They reduce stormwater, sediment, and development impacts.
What is an LOI?
Letter of Interpretation from NJDEP.
What does an LOI determine?

How long is an LOI valid?
5 years.
How long can an LOI be extended?
An additional 5 years.
What are the three types of LOIs?
Presence/Absence, Line Delineation, Line Verification
What does a Presence/Absence LOI determine?
Whether wetlands exist on a site.
What does a Line Delineation LOI do?
NJDEP determines the wetland boundaries.
What does a Line Verification LOI do?

150 feet.
How narrow can an Intermediate transition area become?
10 feet.

3–4 months.
How long are freshwater wetland permits valid?
5 years.

What are FW1 and FW2 waters associated with?
Exceptional Resource Value wetlands.
What mapping tool can identify threatened and endangered species habitat?
NJ GeoWeb.
