About the Coalition
The Jefferson County Stormwater Quality Coalition consists of the Jefferson County Drainage District No. 7, Jefferson County, City of Nederland, City of Port Neches, City of Port Arthur, and the City of Groves. The coalition was formed in February 2008 as an effort by the members to assist one another in complying with stormwater quality regulations established by the Texas Commission on Environmental Quality.
