Preparing for the Storm:
Recommendations for Management of Risk from Coastal Hazards in Massachusetts
Chapter 3 - Infrastructure Inventory
Table 1 - Rating system for the condition of coastal structures (modified after Bourne Consulting Engineering, 2006).
| Condition |
Definition* |
Action Required |
| A |
Excellent |
Structure is like new and expected to withstand major coastal storm without damage. Landform (beach, dune, or bank) is stable and will provide adequate protection from major coastal storm. |
None |
| B |
Good |
Structure exhibits very minor problems, superficial in nature. Minor erosion to landform is present. Structure and landform are adequate to provide protection from a major coastal storm with no damage. Actions could be taken to prevent or limit future deterioration and extend life of structure. |
Minor |
| C |
Fair |
Structure is sound, but may exhibit minor deterioration, section loss, cracking, spalling, undermining, and/or scour. Structure is adequate to withstand major coastal storm with little to moderate damage. Actions should be taken to reinforce structure to provide full protection from major coastal storm and to extend life of structure. Moderate wind or wave damage to landform exists. Landform may not be sufficient to fully protect shoreline during a major coastal storm. Actions should be taken to provide additional material for full protection and extended life. |
Moderate |
| D |
Poor |
Structure exhibits advanced levels of deterioration, section loss, cracking, spalling, undermining, and/or scour. Structure should be monitored until repairs or reconstruction can be initiated. Reconstruction is required to regain full capacity of structure to resist a major coastal storm. Landform is eroded and its stability is threatened. Landform is not adequate to provide protection during major coastal storm. Actions to recreate landform to provide full protection from a major coastal storm are required. |
Major |
| F |
Critical |
Structure exhibits critical levels of deterioration, section loss, cracking, spalling, undermining, and/or scour. Structure provides little or no protection from a major coastal storm. Complete reconstruction of the structure is necessary to regain full protective capacity. Landform is eroded and integrity is lost. Landform stability is severely compromised, rate of erosion or material loss may be increasing, and landform does not provide adequate protection from a major coastal storm. Actions to recreate landform to provide full protection from a major coastal storm are required. Conditions of structure and landform may warrant emergency stabilization as failure may result in potential loss of property and/or life. |
Immediate |
* Based upon perceived immediacy of action and potential to cause damage if not corrected.
