Marsh Edge Erosion
The marsh edge loss vector data layer was created to identify, quantify and visualize erosional changes in the footprint of the coastal back bay marshes from 1977 to 2012. This layer is focused on loss of marsh edge and does not examine areas that advanced through sediment accretion.
Mapping Inequity - Historical Redlining Data
Redlining is a historic practice with present-day implications. During the 1930s and 1940s, several cities were mapped by the HOLC (Home Owners’ Loan Corporation) to assess neighborhoods based on the financial security of providing mortgages. Neighborhoods were graded in four categories (A, B, C and D), where A implied a minimal risk for investors and D, colored red, implied a “Hazardous” risk. The identification of hazardous neighborhoods was driven by several factors, including race, limiting the access to home ownership to African American communities and segregating cities. The data comes from The Mapping Inequality Project. Please note that areas without data mean that there is no data available, not that these areas were necessarily free of redlining.
NJDEP Environmental Justice Overburdened Communities
Census blocks identified as overburdened communities based on thresholds for low-incomes households, minority status, and limited English proficiency are used to evaluate the contributions of certain commercial and industrial facilities to existing environmental and public health stressors in these communities when reviewing certain permit applications.

Tide Gauge: Atlantic City, NJ Tide Gauge Total Water Levels Table
Emission Scenario: Moderate emissions
Timeframe: 2030 Planning Horizon
SLR Estimate: At least a 95% Chance of Exceeding - 0.3 ft.
Flood Event: Permanent Inundation - 0 ft. above MHHW
Total Water Level Estimate: 0.3 ft.
Total Water Level Estimated Mapped (nearest ft.): 0 ft.
Emission Scenario Selection
Choose an emissions scenario based on future fossil fuel use and policy decisions.
- High GHG emissions - Corresponds to a future consistent with the strong, continued growth of fossil fuel consumption.
- Moderate GHG emissions - Corresponds to a future consistent with current global policies.
- Low GHG emissions - Corresponds to a future consistent with the global goal of limiting warming to 2°C above early industrial (1850-1900) levels.
Tide Gauge Selection
Choose the nearest tide gauge or the ‘most suitable’ tide gauge based on your own experience and judgement.
Timeframe Selection
Select Planning Horizon
Choose an appropriate planning horizon relevant to your planning task.
2030 to represent a near-term planning horizon for assets that may be short-lived.
2050 to represent longer-term regional planning horizons (e.g., long-range transportation planning) or the life of a current 30-year mortgage. It is also the currently assessed point to which sea-level rise values are “locked in” regardless of whether emissions increase or decrease.
2100 to represent a planning horizon for long-lived assets that will last for decades or investments that need to be designed to adapt to uncertain long-term projections for sea-level rise.
2150 to represent a planning horizon considering multiple future generations and policy decisions through the early part of the next century.

Flood Hazard Overlays
Total Water Level
Total Water Level - The ‘stillwater’ inundation above Mean Higher High Water. These water levels allow you to visualize the impact of future sea level rise combined with potential flood events up to 20ft of inundation.
Sea Level Rise
Levels represent inundation at high tide. Areas that are hydrologically connected are shown in shades of blue. Low-lying areas, displayed in green, are hydrologically "unconnected" areas that may flood.
SLR Mapping Confidence
Confidence level of Sea Level Rise estimates. Blue areas denote a high confidence of inundation, orange areas denote a high degree of uncertainty, and unshaded areas denote a high confidence that these areas will be dry given the chosen water level.
HAND Inundation Levels
Height Above Nearest Drainage (HAND)-based inundation modeling provides an approximation of flood inundation from the nearest water stream and is calculated across HUC6 watershed units.
Sandy Surge Extent
Areas impacted by Hurricane Sandy storm surge. Created from field-verified High Water Marks (HWMs) and Storm Surge Sensor data from the USGS.
