In the area you have selected (San Diego) coastal flood hazard is classified as medium according to the information that is currently available. This means that there is more than a 20% chance of potentially-damaging coastal flood waves occurring in the next 10 years. Based on this information, the impact of coastal flood should be considered in different phases of the project for any activities located near the coast. Project planning decisions, project design, and construction methods should take into account the level of coastal flood hazard. Further detailed information should be obtained to adequately account for the level of hazard.
Climate change impact: According to the IPCC (2013), there is high confidence that extremes in sea level will increase with mean sea level rise yet there is low confidence in region-specific projections in storm surges. Projects in low-lying coastal areas such as deltas, or in island states should be designed to be robust to projected increases in global sea level.
