The Tampa Bypass Canal, including several concrete control structures, was built in the 1960s and 1970s to reduce the potential for flooding by redirecting floodwaters from the Hillsborough River to Tampa Bay. More recently, the floods of 1960 included a stationary front that lay across north-central Florida from March 15 to 18 and two major storms in September, hurricane "Donna" and tropical storm "Florence," with the most intense rainfall being associated with hurricane "Donna," which passed over central Florida on September 10 and 11. The largest flood of record was the flood of 1933, which was caused by intense rainfall associated with a tropical hurricane passing across central Florida from the Atlantic Ocean on September 4, 1933. * National Flood Insurance Changes Backgrounder * Homeowner Flood Insurance Affordability Act Fact Sheet Click on the documents below about these changes and how they may affect your coverage. Important changes in the National Flood Insurance Program took effect April 1, 2015, making flood insurance more affordable for most homeowners. This standard is used to make accurate measurements of flood elevations, ground elevations, building elevations, and to calibrate gages that supply water level data. Gage data and local elevations are all surveyed in North American Vertical Datum 1988 (NAVD88).
The closest monitoring gage for the Temple Terrace area is the Hillsborough River Gage at Fowler Avenue. There are several gages along the Hillsborough River that provide current and historical information, including water flow, water level, rate of discharge, and peak flow. When flooding spreads out across the floodplain, its energy is dissipated, which results in lower flood flows downstream, reduced erosion of the riverbank, deposition of sediments higher in the watershed, and improved groundwater recharge. Understanding and protecting the natural functions of floodplains helps reduce flood damage and protect resources.
Although the Tampa Bypass Canal, which includes several concrete control structures, and the dam located downstream from the City provide some defense against flooding, there remains a potential for a flood disaster.įloodplains are a natural component of the Hillsborough River. Flooding can occur as a result of heavy rainstorms, tropical storms, and hurricanes. Storm drain systems are also susceptible to annual flood events. The same information will be provided at all the meetings.The potential flooding source in the City of Temple Terrace is the Hillsborough River. Representatives from FEMA, Hillsborough County, and the city of Tampa will be in attendance.

He is also considering hiring an engineer to look at the validity of the proposed new coastal flood plain. He is organizing a community meeting to learn more. South Tampa realtor John Hudson agrees it’s nerve-wracking. “Alarmed concerned afraid not understanding, and what needs to happen is communication so they understand what it’s going to do to our housing market,” said Kathy Walsh, CEO of Coast to Coast Insurance.

The city of Tampa also sent a letter to residents about the preliminary maps. “It's really all the coastal area started in Ruskin, the old Sun City, goes all the way up to Town 'N Country and Oldsmar and then Pinellas is going through the same thing, so it goes completely around the bay,” Henry said.
