Flood Hazard Areas
What is a Flood Hazard Area?- Floodway- Flood Fringe- “Regulated Water” - Water that drains
greater than or equal to 50 acres, excluding certain canals and coastal wetlands

Flood Hazard Areas
- Inundated by a “Design” Flood– Tidal (100-year)– Fluvial (100-year + Safety Factor)
- 100-Year Flood – 1% Chance of Being Equaled or Exceeded Within A
One-Year Period

Riparian Zones
Different, and also regulated in N.J.A.C. 7:13
Like a buffer 50, 150 or 300 feet from a regulated
water Follows the channel, not the floodway

Riparian Zones
300 Feet: Category One waters and certain upstream tributaries
150 Feet: Trout waters, T&E habitat, acid producing soils
50 Feet: All else ….

Goals
Flood storage, unobstructed flow Keep new construction out of the flood
hazard area Protect plants and critters No adverse impact from one property
owner upon another

The NJPDES Program
New Jersey Pollutant Discharge Elimination System
Federal model Pollutant – broad definition Discharge of a pollutant without a permit is
prohibited Permits
– Five years, generally– Individual permits & general permits

Example
Discharge to surface water (DSW) permit- Specifies pollutants that can be discharged- Specifies quantity of allowable discharge
(effluent limitations)- Must measure specified pollutants- Report / self-certify on monitoring report
forms (MRFs)- Responsible corporate officials

- Discharge to ground water (DGW)- Underground injection control- Treatment works approvals- Indirect users / delegated local agencies
(DLAs) – industrial pretreatment program– Mini-NJDEPs

Treatment Works Approvals
Wastewater NJDEP evaluates design and ability to meet effluent
standards – and the evaluation and approval actually occurs after the NJPDES permit issues
Projected flow criteria– Example: bowling alley = 200 gpd / alley
More than two buildings or greater than / equal to 8000 gpd
No single family residences, except single property with aggregate wastewater design flow > 2000 gpd
Other
