The District developed its first Regulatory Plan in 1990 to address issues with localized flooding. There have been three different Regulatory Plans developed throughout the years. The latest and current Regulatory Plan was adopted in 2013. The 2013 Regulatory Plan requires permitted well owners located in Regulatory Area A to reduce their groundwater usage by 30% of the total water demand by 2014 as well as reduce their groundwater use by 60% of their total water demand by 2025.
