Wetland Loss in the Matanuska-Susitna Borough
1.5 Mb .pdf (July 2018) This report quantifies the wetlands filled by type and watershed in an expanded “Core Area” of the Mat-Su Borough. Historic imagery was compared to recent high-resolution imagery and elevation data to delineate all the wetlands that had been filled since the modern era of settlement.
Homer Wetland Complexes and Strategies
2.4 Mb .pdf.(29 December 2013) This is a 24″x 38″ map poster that defines the wetland complexes in the City of Homer and the describes management strategies associated with each complex. The management strategies should be addressed in an application for a permit to discharge fill into City of Homer wetlands.
