  1. Bridges Predicted to be at High Flood Risk Benjamin Davis Michael Kazalis

  2. Factors to Consider • Streams and Road Intersections • Soil Drainage Class • Land Cover • Predicated Precipitation Change • Flood Zones • Bridges at Risk • Bridge Condition

  3. Soil Drainage Class • Well drained areas assigned a value of 1 • Moderately well drained areas assigned a value of 2 • Poorly drained areas assigned a value of 3

  4. Land Cover • Forests and shrubs get a value of 1 • Wetlands and open water get a value of 2 • Developed lands and cultivated crops get a value of 3

  5. Predicted Precipitation • Looked at the projected change in 50 years • Precipitation is projected to increase everywhere in Oswego County in 50 years • Split these increase into three groups • Low increase was given 1 • Medium increase was given 2 • Large increase was given 3

  6. Combining Factors • Soil Drainage Class • Land Cover • Road and Stream Intersection • Predicted Precipitation change

  7. Flood Zones • Low Risk (X, X500) - given a 1 • Medium Risk (VE) - given a 2 • High Risk (A, ANE, ANI, AO) – given a 3

  8. Consider Bridges • With all of the factors considered there are still a significant amount of high risk flood areas • We decided to consider only bridges at a flood risk

  9. Bridge Condition • The bridge file contains the condition of each bridge as a value from 253 – 999, with 999 being the best condition. • Bridges with values of 801 – 999 were assigned minimal • Bridges with values of 501 – 800 were assigned moderate • Bridges with values of 376 – 500 were assigned high • Bridges with values of 253 – 375 were assigned critical
