Lower Platte Cumulative Impact Study

Land use has changed dramatically in the Lower Platte River Corridor over the past 80 years, and the rate of change has been accelerating since the early 1990s. A multi-year study is underway to determine how those changes could impact the future of the corridor.

Using historical data from six different time periods, the Cumulative Impact Study (CIS) is examinining the cumulative effects of activities and practices over time and their impact on the habitat and Platte River. The project is being sponsored by the Lower Platte River Corridor Alliance and the US Army Corps of Engineers.

Project Timeline

Phase I - Scope Development was completed in August 2005.

Phase II- Data Acquisition currently is underway and includes acquisitions of aerial photos and transect data for six time periods (1850, 1938, 1950's, 1970's, 1993, and 2003), land classification, a hydrologic study looking at changes in the river over time, and the development of an online internet mapping service to access the GIS information (via the NRD MapMaker system).

Phase III - Prediction Model Development is an optional phase that could be used to predict the impact of future projects such as levees on the river corridor.
