Some areas of the Hobe Heights neighborhood that was hit by 11-12 inches of rainfall this past week are still underwater on Friday June 5, 2020, in Hobe Sound. The flood water damaged several homes and some residents say more needs to be done to prevent flooding in the area. "We have seen this before but not like this," said Linda Wassuta (not pictured). "This is just totally chaotic."

MARTIN COUNTY — While climate change brings with it more flooded streets and property damage, the county is developing a plan to prepare for rising sea levels.

After analyzing how vulnerable the county’s coastal areas were to flood risks, staff members made recommendations to county commissioners on how to improve the resilience of the county’s shores. They include retrofitting existing infrastructure, promoting rainwater harvesting and improving community discussions on the impacts of climate change on the county.

“We don’t (want to) take a one-, two- or three-year shot at this and then it just kind of drifts off the radar,” Commissioner Doug Smith said during Tuesday’s commission meeting.

According to projections by the National Oceanic and Atmospheric Administration, from average sea levels in 2010, Martin County sea levels will rise 17 inches by 2040 and 40 inches by 2070.

The county received a $75,000 grant from the Florida Department of Environmental Protection in 2019 to analyze current and future effects of flooding from sea level rise, storm surge, heavy rains and other sources; develop resilience plans; and implement those plans.

According to the Public Works Department, flooding is becoming worse, happening more frequently and remaining longer. Last week’s storm left several areas submerged, including commonly flooded areas Port Salerno, Sewall’s Point and near Jupiter Island.

“By identifying these areas, we can begin to focus our planning effort… so we can better understand what actions are the most efficient to solve the problems,” said county Coastal Engineer Kathy Fitzpatrick.
