Completed up to date ECA’s for domestic watersheds utilizing LiDAR derived digital elevation models integrated with hydrological and hypsometric analysis in ArcGIS using python-based models. Developed a custom ArcGIS model to automate parts of the process for future ECA calculations. Utilized LiDAR canopy height models to estimate hydrological recovery of existing disturbances. Projected impact of proposed harvesting and road building activities were analyzed, including for partial cut silviculture systems.
