To report flooding issues or to offer your flooding observations related to Irma and/or the August 25th – 27th rain event, you can submit information online or contact the Lee County Flood Hotline at 239-533-8888.

Sign up for Email Notifications for Flood related information and optionally complete a flooding questionnaire to enhance our consultants' data by uploading photos, providing observations and sharing data for flooding experienced during the August 25-27 Rain Event or Hurricane Irma.  This information is helpful in our evaluation of the flood events and identifying possible solutions.

Update #1 - Hurricane Irma and flooding issues


Overview

The County experienced two historic rainstorms in 2017 between the dates of August 25 and September 10. While these two storm events covered a great deal of the County, some areas received more than 20 inches of rain during this short period of time. Rainfall at this intense level coupled with Hurricane Irma’s storm surge exceeded the carrying capacity of our natural and manmade drainage features. Consequently, the County is working on its stormwater system using the multi-faceted approach explained below.


Phase 1: Clearing Bodies of Water

The county immediately identified and removed trees and other debris from waterways that were potentially impeding flow and contributing to flooding. This work continues based on field reports. Estimated completion of the first pass of phase 1 is mid-December. Additional passes may be required.



Phase 2: Initial Flooding Assessment Projects

The county is in the process of identifying causes and contributing factors to the recent flooding and looking at what can be done to improve drainage on a relatively short-term basis.  Local consultants are in the field identifying blocked pipes, culverts, ditches, canals, creeks and streams for clearing. They are also reviewing development permits to determine if they are causing or contributing to the flooding problem. Data from this effort will enable the county to proceed with early activities that will provide relief prior to next rainy season. All this information will be documented on an interactive website where the public can track progress and participate and share their observations. Estimated completion of initial assessments is January 2018.

Initial Flooding Assessments Map

This map depicts the study areas for the initial flood evaluation. Specifically, the outlined areas are the watersheds that caused or contributed to neighborhood flooding during the rainfall events of August 25-27 and Hurricane Irma. The different colors indicate the consultant chosen to conduct the work. Individual neighborhoods that experienced flooding are not shown.

Phase 3: Flooding Long Term Recovery

The goal is to establish a plan to reduce flooding on a larger regional scale. It is important to understand that water management in our area is a complex system and has to be addressed holistically. What you do in one part of the system or watershed can have unintended consequences elsewhere. To consider larger projects such as dredging, diking, diverting, berming or storing water, a series of tools are used to evaluate projects to ensure the project would perform as intended. Those with the most promise are then selected for budgeting and implementation. This next step includes grant applications, land acquisition (if necessary), permitting, design, bid and construction. We expect to present options to the board in late 2018.
