Built Environment in the Floodplain

This metric tracks changes in land-use in the floodplain using the Washington Department of Fish and Wildlife’s High Resolution Change Detection (HRCD) data. This dataset quantifies canopy loss, tracks changes in the amount of impervious and semi-impervious surfaces and provides information as to the likely cause of change, allowing FFTF partners to better understand interactions between communities and land in the floodplain. HRCD data is highly accurate and able to detect changes as small as 1/20th of an acre. “Built Environment” is defined as human dominated land cover such as roads, buildings, and warehouses.
