CRSSA TECHNICAL REPORT:
Lathrop, R.G. and S. Haag. 2007. Assessment of Land Use Change and Riparian Zone Status in the Barnegat Bay and Little Egg Harbor Watershed: 1995-2002-2006. Rutgers University, Grant F. Walton Center for Remote Sensing and Spatial Analysis, New Brunswick, NJ, CRSSA Report#2007-04.

The user agrees to abide by the following terms of use:
1. The Grant F. Walton Center for Remote Sensing and Spatial Analysis (CRSSA), Rutgers University, disseminates this data layer as-is and makes no warranty, expressed or implied, nor does the fact of distribution consitute such a warranty.
2. The spatial resolution of the raster data may not be appropriate for some site specific applications.
3. The user will read all metadata for this data product as well as any documents stated in the Cross Reference section.
4. CRSSA, Rutgers University, will not be held responsible to further maintain the disseminated data.

A. Flood-prone areas as defined by: 1. NJDEP/USGS documented and undocumented flood-prone areas. The flood-prone designation represents an average 1 in 100 change that the designated areas will be inundated in any year. The DEP-distributed flood-prone documentation was taken directly from USGS flood-prone maps, itself distributed by the USGS as county-wide Integrated Terrain Unit Mapping (ITUM) layers. 2. Special Flood Hazard Areas (SFHAs) were mapped from the county level FEMA Q3 datasets. SFHAs are areas subject to inundation by a flood having a one-percent or greater probability of being equaled or exceeded during any given year. This flood, which is referred to as the 1% annual chance flood (or base flood), is the national standard on which the floodplain management and insurance requirements of the NFIP are based.
B. Riparian Soils as defined by the NRCS SSURGO county soil surveys: 1. Hydric soils were defined as soil association where at least one major component soils (greater than 25% average representation in the association) was defined as hydric. 2. Soils with seasonal depth to high water table of 18" or less were extracted for all soil association with a minimum annual water depth of 46 cm (18") or less.
C. Wetlands as defined by NJDEP 1995/97 landcover updated with the CRSSA 2000/1999 development update. All wetland types as well as 'Agricultural Wetlands (Modified)' that fall within 33 feet of a stream were considered to be hydrologically connected to streams. The 33 foot threshold was used as this distance represents the National Mapping Accuracy Standard for the possible inaccuracy in the spatial location of a mapped feature.
D. 300 foot buffer of all water features as defined by NJDEP 1995/97 landcover.
