The location of the LOMA is referenced in the legal description of the letter itself. If you cannot clearly see the location of the roadway, do not attempt to drive through floodwaters.FEMA National Flood Hazard Layer Interactive MappingįEMA Flood Insurance Rate Map information can also be found on the Nassau County Property Appraiser's Interactive Mapping site. Attempting to drive through flood waters can be very damaging to the automobile.Submerged culverts can create very strong currents and the locations of roadside canals and ditches are often not recognizable.The calm water surface is often very deceiving, but can be very harmful or fatal. Rainfall-induced flooding generally rises very slowly with almost no horizontal flow movement. Stay Out of Flood WatersĬoastal surge flooding is generally considered as posing the greater risk to life due to the rapidly changing water levels and other accompanying dangers associated with a tropical cyclonic storm event. Driving conditions are also seriously impacted with standing water over roads. This broad shallow flooding can create severe property damage conditions for older houses and buildings that were constructed to prior building code. Roughly 80% of the 52” average annual rainfall occurs during the months of May through October, with approximately 65% of that occurring during the months of June through September.Ĭombining the intense rainfall with a topography that averages approximately 1 foot of elevation change for 1 mile of travel can produce broad expanses of shallow sheetflow flooding conditions. The summer “wet” season is vital to the region’s environment to offset the winter “dry” season. Surge flooding can occur quite rapidly with extremely damaging impacts to structures and quickly create life threatening conditions.Ĭollier County is located within a sub-tropical environment and is subject to intense thunderstorms and tropical cyclones (hurricanes). The combination of atmospheric pressure differences in the storm and the effect on the Gulf waters from the high wind speeds creates a “mound” of seawater that is pushed onshore. Because tropical systems spin in a counterclockwise direction, in Collier County the highest storm surge occurs along the coastline just south of the center of the storm. Coastal Surge FloodingĬoastal surge flooding is primarily caused by tropical storms and hurricanes. Visit the Flood Map Information webpage to view the DFIRM. The DFIRM delineates the broad areas subject to shallow flooding. This combination of flat terrain, sub-tropical climate, and coastal boundary creates large areas subject to flood risk. The DFIRM shows the areas subject to flooding from coastal surge as well as rainfall. The County is also subject to severe impacts from tropical cyclones (tropical storms and hurricanes). The climate is sub-tropical which can create large numbers of intense thunderstorms during the summer “wet” season. 2021 Collier County BCC Redistricting InformationĬollier County is a very flat community along the Gulf Coast of Florida.Approved Updates to the Administrative Code.Administrative Code for Land Development Amendments.Administrative Code for Land Development +.Annual Update and Inventory Report (AUIR).Collier Boulevard/Interstate 75 Innovation Zone Overlay (CBIIZO).US 41 East Corridor Zoning Overlay Project Archive.East Naples Community Development Plan Archive.East Naples Community Development Plan +.Rural Lands Stewardship Area History and Archive.TDR Program Rural Fringe Mixed Use District.Rural Fringe Mixed-Use District Archive.Collier County Planning Commission (CCPC) +.Historic & Archaeological Preservation Board Archive.Historic & Archaeological Preservation Board +.Short-Term Vacation Rental Registration.Development Services Advisory Committee (DSAC) +.Consumer Information: Working with Contractors.Right-of-Way (ROW) Ordinances, Resolutions, and ROW Permitting Handbook. ![]()
