The engineers are available to determine if your property is located in a Special Flood Hazard Area and answer questions about flood maps, flood zones, base flood elevations (BFE), flood protection, and flood insurance. Land Development engineers can provide one-on-one information regarding the FEMA mapping of the Special Flood Hazard Areas (SFHA) at the Public Works Land Development Permit Counter, located in the Marin County Civic Center, Room 308 or via phone at 41. These maps are for planning, awareness and educational purposes only and should not be used for site-specific analysis.The County of Marin administers the Federal Emergency Management Agency (FEMA) National Flood Insurance Program (NFIP) and the Community Rating System (CRS) Program for unincorporated areas of Marin County. These limitations may result in an over-estimation of flood risk in some areas and an under-estimation of flood risk in other areas.
No coverage of inland coastal areas on Eyre Peninsula and Limestone Coast beyond the extent captured in the project, so any land further in-land will not show in the scenarios. No consideration of coastal erosion hazard. can enough sea water flow through a restriction to fill the low lying area during the duration of the storm surge event). No consideration for hydraulic flow restrictions, such as the width and depth of channel flow paths for flooding (i.e. No allowances for future changes to the landform, through uplifting or movement of tectonic plates or through the installation of man-made structures since the original data were captured. The coastal flood mapping has limitations which users need to be aware of, including: Inform policy-making and strengthen partnerships in managing coastal hazards.Įxample of limitation: identified as being at risk of flooding during a 1 in 100 year storm with a 1m sea level rise, but there is no current connection, or pathway, for the sea to reach this area. Visualise the potential impacts from different sea level rise scenario’s through maps, and. Identify areas that may be vulnerable to coastal flooding at a regional scale,. The main goals of the coastal flood maps are to: The maps identify areas on Eyre Peninsula and the Limestone Coast that may be vulnerable to coastal flooding due to storm surge and/or sea level rise. This interactive Flood Mapping Tool has been developed as a result of the partnerships between the Limestone Coast Local Government Association, the Eyre Peninsula Landscape Board, the Eyre Peninsula Local Government Association, the Coast Protection Board and the Department for Environment and Water. Therefore it is important to identify areas that are likely to be affected by storm events to determine the most appropriate management strategies, such as avoid, retreat, accommodate or do nothing. Sea level rise leads to increased frequency and depth of flooding in coastal areas. Significant coastal storm events in recent years have highlighted the need for better information to identify areas that may be vulnerable to coastal flooding and prioritise areas that require adaptation strategies.Ĭlimate change is expected to increase the frequency, intensity and impacts of some weather events, such as coastal storms.
