FLOOD PLAIN MAP SERIES
The International Water Institute has created a series of "LIDAR Viewers" that are available on their website to view elevation information in two foot intervals for the entire Red River Basin. This site allows the user to anticipate at what flood stage property may be threatened and also allows them to calculate their approximate sandbag needs through easy to use measuring tools. The County has created an interactive website that allows residents to view parcel and building critical elevation information based on flood models provided by a third party. See where the Flood Control District has projects around Maricopa County. This information is delivered to the public in a number of formats. Find out if your property in Maricopa County is in a floodplain. Elevation contours are acquired using light detection and ranging (LIDAR) methods and available upon request in the NAVD 1988 datum. Elevation contours have been created for the County in two foot intervals, and for the metro area in one foot intervals. Other Water Resource Links and InformationĬass County has obtained data over the years that can assist homeowners in planning for flooding on their property.Northern Cass Public School District #97.Central Cass Public School District #17.NOAA Sea Level Rise: data from the National Oceanic and Atmospheric Administration Office for Coastal Management depicting potential sea level rise (SLR) and its associated impacts on the nation's coastal areas.It represents all of the public and many of the private roadways in Massachusetts.
MassDOT Roads: official state-maintained street transportation dataset developed by the Massachusetts Department of Transportation.The data also provides critical information to citizens who live or work in areas that may need to be evacuated as a hurricane approaches. It provides critical information to aid local public officials in evaluating evacuation decisions as a hurricane approaches. Hurricane Evacuation Zones: data layer depicts areas that may be inundated by storm surge or isolated by storm surge waters.Hurricane Inundation Zones: data representing worst-case Hurricane Surge Inundation areas for Category 1 through 4 hurricanes striking the coast of Massachusetts.FEMA Q3 Flood Zones: data layer showing areas for which the newer National Flood Hazard Layer are not available.This dataset represents the areas inundated in a 100-year and 500-year flood. FEMA’s National Flood Hazard Layer: a compilation of effective Flood Insurance Rate Map (FIRM) databases and any Letters of Map Revision (LOMR) that have been issued.Tidal flooding can also result in the salinization of land leading to loss of shaded areas and green space. Rising sea levels may erode shorelines, threaten coastal drinking water supplies with salt-water intrusion, disrupt septic systems and sewage treatment, and displace residents. Furthermore, flooding can temporarily or permanently displace residents. Flooding can result in exposure to contaminated flood water, debris and physical hazards such as downed wires, loss of electricity and/or heat, unsafe food and drinking water, and mold growth. Projected increases in precipitation levels may exceed the capacity of existing infrastructure, such as drainage systems, bridges, culverts, and sewers, to divert water. Rising sea levels which can cause increased tidal flooding and higher storm surges.Increasing storm-related inland and coastal flooding In accordance with FEMA, a multi-year project to reexamine Baltimore Countys flood zones and develop detailed, digital flood hazard maps has been completed.
