This is the home page for the Great Lakes Restoration Initiative (GLRI) project titled Land Use Planning Impacts on Near-Shore Pollution Loading in the Great Lakes. This project is intended to facilitate land use planning for reducing runoff and improving water qualiy in the Great Lakes through two separate approaches:

    1. Assessment of shoreline (2 kilometers inland) areas using i-Tree Hydro to determine the impact of current vegetation and impervious surfaces on annual pollution loading and estimate potential changes.

    2. Assessment of all HUC8s in the Great Lakes basin using i-Tree Buffer to map areas of greatest concern for pollutant loading into the Great Lakes.

To view the reports, begin by selecting a Great Lake:
