Improperly planned rain gardens and fences can lead to water retention issues, mosquito concerns, and potential flooding. In areas like Cape Coral and Lee County, Florida, floodplain and easement rules may restrict fence placement to prevent obstruction of water flow and ensure compliance with local regulations. Poorly designed fences can redirect runoff, damage neighboring properties, or interfere with drainage systems. Homeowners must also consider the impact of saturated soil and strong winds on fence stability. The study highlights the importance of addressing these risks during the planning and installation process.
