Community Rating System Special Flood Hazard Areas

The Community Rating System (CRS) is a voluntary incentive program that recognizes and encourages community floodplain management practices that exceed the minimum requirements of the National Flood Insurance Program (NFIP). Over 1,500 communities participate nationwide. In CRS communities, flood insurance premium rates are discounted to reflect the reduced flood risk resulting from the community’s efforts that address the three goals of the program: * Reduce and avoid flood damage to insurable property * Strengthen and support the insurance aspects of the National Flood Insurance Program * Foster comprehensive floodplain management An area having special flood, mudflow or flood-related erosion hazards and shown on a Flood Hazard Boundary Map (FHBM) or a Flood Insurance Rate Map (FIRM) Zone A, AO, A1-A30, AE, A99, AH, AR, AR/A, AR/AE, AR/AH, AR/AO, AR/A1-A30, V1-V30, VE or V. The SFHA is the area where the National Flood Insurance Program's (NFIP's) floodplain management regulations must be enforced and the area where the mandatory purchase of flood insurance applies. For the purpose of determining Community Rating System (CRS) premium discounts, all AR and A99 zones are treated as non-SFHAs.
Floodplain FIRM Panels

Location and attributes for FIRM hardcopy map panels. The spatial entities representing FIRM panels are polygons. The polygon for the FIRM panel corresponds to the panel neatlines. FIRM panels must not overlap or have gaps within a study. In situations where a portion of a panel lies outside the jurisdiction being mapped, the user must refer to the S_Pol_Ar table to determine the portion of the panel area where the FIRM Database shows the effective flood hazard data for the mapped jurisdiction.
Hawaii Lava Flow Hazard Zones

Feature layer for the tutorial [Analyze volcano shelter access in Hawaii]. This layer is a copy of the [Volcano Lava Flow Hazard Zones] layer by HawaiiStateGIS. The boundaries and classification of lava flow hazard zones on Hawaii Island were first mapped by the US Geological Survey in 1974. This [classification scheme] divides the island into 18 major zones that are ranked from 1 through 9 based on the probability of coverage by lava flows. The risk levels are based primarily on the location and frequency of historic eruptions (those for which there are written records or that are known from the oral traditions of the Hawaiians) and the geologic mapping and scientific dating of the old flows from prehistoric eruptions. Much of the USGS work was based on a paper called [Geologic Map of the Island of Hawaii] by Edward Wolfe and Jean Morris.
AirNow Monitoring Site Data (Last 24 hours – Ozone and PM only), US EPA, OAR, OAQPS

This United States Environmental Protection Agency (US EPA) feature layer represents site data, updated hourly concentrations and [Air Quality Index (AQI)] values for the last 24 hours received from each monitoring site that reports to [AirNow]. The values are for Ozone and Particulate Matter (PM) only. Map and forecast data are collected using federal reference or equivalent monitoring techniques or techniques approved by the state, local or tribal monitoring agencies. To maintain "real-time" maps, the data are displayed after the end of each hour. Although preliminary data quality assessments are performed, the data in [AirNow] are not fully verified and validated through the quality assurance procedures monitoring organizations used to officially submit and certify data on the [EPA Air Quality System (AQS)]. This data sharing, and centralization creates a one-stop source for real-time and forecast air quality data. The benefits include quality control, national reporting consistency, access to automated mapping methods, and data distribution to the public and other data systems. The U.S. Environmental Protection Agency, National Oceanic and Atmospheric Administration, National Park Service, tribal, state, and local agencies developed the [AirNow] system to provide the public with easy access to national air quality information. State and local agencies report the [Air Quality Index (AQI)] for cities across the US and parts of Canada and Mexico. [AirNow] data are used only to report the AQI, not to formulate or support regulation, guidance or any other EPA decision or position.
National Shelter System Facilities

The National Shelter System feature class/shapefile contains facilities that can house individuals in the event of an issued evacuation for the facilities area. This feature class/shapefile’s attribution contains physical, demographic, and capacity information for facilities in the continental United States and some of its territories. The purpose of this feature class/shapefile is to provide accurate locations for a potential shelter in the event of a disaster. The facilities included have been designated as a Shelter by either the Federal Emergency Management Agency (FEMA) or the American Red Cross (ARC). THIS LAYER SHOULD NOT BE USED TO DETERMINE THE OPERATIONAL STATUS OF A FACILITY DURING AN ACTIVE EMERGENCY.

RISPP - Bridge Assets Exposed to Storm Surge and SLR by 2100

This layer was created by the Rhode Island Statewide Planning Program as part of the 2016 Municipal Transportation Assets Vulnerable to Sea Level Rise and Storm Surge Project. The layer depicts bridges over 25 ft. in length potentially exposed to storm surge and sea level rise before 2100, based on predictions of seven feet of sea level rise for the State of Rhode Island by the Rhode Island Coastal Resources Management Council (CRMC). The bridge locations, and much of the attribute data, originates from a layer maintained internally by the Rhode Island Department of Transportation. The scenario depicting seven feet of sea level rise plus the storm surge from a 100-year storm event, and the attendant water heights, originated with the STORMTOOLS data set created by CRMC. Other data came from the Rhode Island Public Transportation Authority. This layer was created by the Rhode Island Statewide Planning Program as part of the 2016 Municipal Transportation Assets Vulnerable to Sea Level Rise and Storm Surge Project.

Drought Regions of New Jersey

This data delineates New Jersey drought regions. Drought regions provide a regulatory basis for coordinating local responses to regional water-supply shortages. The six drought regions are based on watershed and water-supply considerations. Drought region boundaries coincide with municipal boundaries as referenced by the N.J. Dept of Environmental Protection (NJDEP). Each municipality in New Jersey is assigned to a drought region based on the watershed covering and supplying water to the municipality. Each data record of the file includes name of the drought region. This is the second version of the drought regions. It differs from the original delineation in two ways: 1) The number of drought regions were expanded from five to six in order to account for water-supply issues identified for the New Jersey coastal plain. The original version included the north part of the Coastal Plain in the central region. Version 2 separates a north coastal region, consisting of Monmouth and northern Ocean Counties, from the coastal region to the south. 2) Municipalities in Mercer County receiving water from the Trenton Water Dept. were moved into the southwest region from the northwest. Pennington and Hopewell boroughs were also moved to the southwest region. This is the third version of the drought regions and was released in May 2004. There are two changes from the second version. Roosevelt Boro in Monmouth County was moved to the southwest drought region (from the coastal north) and Berlin Twp in Camden County was moved to the coastal south drought region (from the southwest). Both changes were made in recognition of the location of actual water supply to these municipalities.
