Description: These zones represent monthly tide inundation areas (areas that would be flooded by normal tides once per month, on average). The water level mapped in these inundation areas is the Extreme Monthly High Water (EMHW) level, which is a high water level that is reached approximately once a month. These zones do not, however, consider coastal erosion or wave overtopping, which may change the extent and depth of regular tidal flooding in the future. There are two types of inundation areas: (1) areas that are clearly connected over the existing digital elevation through low topography, (2) and other low-lying areas that don’t have an apparent connection, as indicated by the digital elevation model, but are low-lying and flood prone from groundwater levels and any connections (culverts, underpasses) that are not captured by the digital elevation model. This difference is captured in the “Connection” attribute (either “connected” or “connectivity uncertain”) in each rising tides dataset. We recommend these be mapped as separate colors. -------------------------------This feature is one in a series of coastal flood and erosion hazard zones developed as part of the Santa Barbara County Coastal Hazard Modeling and Vulnerability Assessment. For detailed documentation about how these hazard zones were developed, please see "Santa Barbara County Coastal Hazard Modeling and Vulnerability Assessment: Technical Methods Report," a report prepared by ESA for The County of Santa Barbara in June 2015, as well as “Santa Barbara County Coastal Resiliency Phase 2 Coastal Hazard Modeling: Technical Methods Memorandum,” a report prepared by ESA for the County of Santa Barbara in July 2016.-------------------------------The name of this shapefile reflects the future scenarios and planning horizon that the hazard zone represents, as follows:"emhw_area" + _ + sea level rise scenario + planning horizon-------------------------------Sea level rise scenarios:ec – Existing conditions (2010 water level)s1 – Low sea level rise (27 cm by 2100)s2 – Medium sea level rise (78 cm by 2100)s3 – High sea level rise (153 cm by 2100)-------------------------------Planning horizons:2010 (Existing conditions)203020602100
