Perdido River and Bay SWIM Plan

The purpose of the Perdido River and Bay Surface Water Improvement and Management (SWIM) Plan is to provide a framework for resource management, protection, and restoration using a watershed approach. Protecting and restoring watershed resources is a shared responsibility on the part of numerous watershed stakeholders, including local governments, state and federal agencies, private businesses, and the public. It requires building upon past accomplishments to encompass a wide range of management approaches. Protecting and restoring watershed resources is a shared responsibility on the part of numerous watershed stakeholders, including local governments, state and federal agencies, private businesses, and the public. It requires building upon past accomplishments to encompass a wide range of management approaches. Addressing continuing challenges affecting water quality and natural systems requires a range of strategies. Among these are additional improvements in the treatment and management of stormwater runoff; continued implementation of best management practices for agriculture, silviculture, and construction; and additional efforts to improve wastewater treatment and management. To complement these, long-term protection of critical habitats and associated buffer areas will further help protect water resources. Projects identified in the plan include the following:

  • Stormwater Planning and Retrofit
  • Septic Tank Abatement
  • Advanced Onsite Treatment Systems
  • Agriculture and Silviculture BMPs
  • Basinwide Sedimentation Abatement
  • Riparian Buffer Zones
  • Aquatic, Hydrologic, and Wetland Restoration
  • Estuarine Habitat Restoration
  • Strategic Land Conservation
  • Watershed Stewardship Initiative
  • Sub-basin Restoration Plans
  • Wastewater Treatment and Management Improvements
  • Interstate Coordination
  • Analytical Program Support
  • Comprehensive Monitoring Program
