Flooding of barrier islands: the meeting of the Bay and the Atlantic Ocean

 

 

The percentage of claimants that have flood insurance is 64.07%.

Using the county flood coverage:

  1. We selected from each of the 21 counties everything that was not a in a flood plain (zone <> 'X')
  2. Converted the results into a shapefiles
  3. Queried the shapefiles to find the 100 year flood plain and 500 year flood plain in each county
  4. Converted those results into shapefiles of the 100 and 500 year flood plain
  5. Merged the 100 year flood plain areas of all the counties into one shapefile and did the same for the 500 year flood plain area of all the counties
  6. Selected by theme all the points in the flood points shapefile that intersected the 100 year flood plain of the state and did the same for the 500 year floodplain

From this analysis, it was found that 85.03% claimants are found in the 100 year flood plain, 2.48% were in the 500 year flood plain, and 12.49% were not in the flood plain.

See map below (figure 1) for graphically display.

  Cape May County and the South Jersey shore area had, by far, the largest number of flood points, repeat claims and insurance money paid out. (See figure 2)

Data presented on this web page were gathered from a data table of all flood points in the State of New Jersey since 1978. Specific data were selected from this large database by summarizing the data by specific fields on the data table. For example, in order to find the total insurance money paid out according to zip code, the zip code field on the data table was highlighted and then summarized with the total money paid field. In the summarize window, we selected for the sum function to find the sum of all money paid out according to zip code. This produced a new data table which arranged the desired data into a readable, workable format. This same procedure was used several times to retrieve desired data (total flood points, total repeat claims, and total insurance money paid out) for specific areas (counties, municipalities, and zip codes). This new data sets were then joined with existing data sets to produce new GIS coverages, views, and layouts which can be found in figures 2 & 3.

The planning/zoning policies in these areas do not seem to discourage the siting of businesses and residences in known flood plains due the amount of flood insurance money paid out and the large amount of repeat claims as seen with the figures and the numbers.

 

 

 

 

 

 A suitable policy for municipalities and flood insurance companies regarding flood related reimbursement may be that buildings located in the 100-year flood plain and have been flooded repeatedly (greater than 3 times) in the last 30 years should pay a greater amount of money for their insurance. To live in these flood prone areas, the people will have to pay more money. Municipalities should be denied Federal flood insurance if they allow construction of homes and businesses in both the 100 and 500-year flood plains and have repeated flooding (greater than 3 times in 30 years) because it is a waste of the tax payer's money. Instead of allowing the people to rebuild in these areas, they should be encouraged to build in other areas less prone to serious and destructive flooding. For example, reimburse the people for their losses only if they will relocate. Additionally, 100 and 500-year classifications should be reevaluated, which can result in making better policies regarding flood insurance reimbursements.
