Local Mat-Su salmon habitat situation:

+Borough passed a Fish Passage Ordinance

  • Borough’s riparian setback is not enough
  • Corps not requiring wetlands mitigation on all projects
  • Lack of enforcement on habitat issues on state lands

Potential improvements:

+Borough is pursuing local wastewater treatment +Riparian setback ordinance may be introduced next year +Borough will implement stormwater management +Tri-borough Salmon Commission to address Cook Inlet
