From page 18... ...
The interim FEMA policy (Appendix B) on existing levees requires map development contractors to determine that design standards have been met and that a field inspection or "suitable alternative" be performed to verify that levees appear structurally sound and adequately maintained.

From page 19... ...
Where federal participation can not be arranged, FEMA must use state agencies and private sector capabilities. INSPECTION AND EVALUATION PROCEDURES FOR EXISTING LEVEES Many existing federal and state levees have been built consistent with the recommended design and construction criteria.
|
From page 20... ...
For levees that were built by federal or state forces and assigned to local entities for operation and maintenance, however, the committee believes independent evaluations are necessary as project conditions may have changed considerably since the assignment. Individuals needing information concerning levees may wish to check with state floodplain agencies.

From page 21... ...
This process is similar to NFIP procedures for changing flood insurance maps to reflect new data or the impacts of new flood control structures. In the case of existing levees, the Flood Insurance Study process may or may not have already given a levee credit as providing protection from the 100-year flood.
|
From page 22... ...
Previously Recognized Levees The committee recommends: • FEMA should inventory all levees previously credited as providing protection from the 100-year flood, set priorities, and schedule communities for restudy to reevaluate the levees. Communities with levees credited with removing areas from the 100-year floodplain should have those levees restudied to ensure that the levees meet adopted hydrologic and engineering criteria.
|
From page 23... ...
Levees requiring the greatest and earliest attention should be studied first, and FEMA would finance the preliminary studies to determine if an earlier FEMA decision should be changed. The community would not be required to pay for this preliminary study unless an on-site check gave FEMA reasonable belief that the levee should no longer be considered adequate.
