Watershed: Palouse Basin
Stream Name: Paradise Creek
Date Established: 06/26/2001
Project Status: Complete
Overview
The 100 foot project was done to stabilize the downstream end of the Bridge Street park project. The steep streambanks were resloped to reduce the amount of sediment entering the stream. The Palouse-Clearwater Environmental Institute staff and the AmeriCorps NCCC team laid out erosion control blankets and installed coconut fiber-filled logs planted with wetland plants along the streambanks. These measures helped to stabilize the bank and improve water quality through the water-filtering qualities of wetland plants.

Previous Conditions
Bridge culvert was contributing to erosion on the downstream bank. Steep banks were mowed to the edge by residential neighbors.
Photo History:
Bridge W Before E 06/25/01: Highlighted in this photograph are the previously existing site conditions before excavation began. The east view displays the culvert through which the water flows.
Bridge W Restored E 06/26/01: This photograph was taken in the same location as the previous photograph. The yellow colored streambank is the straw erosion control fabric that minimizes soil runoff. The other exposed bank was seeded with grass.
Bridge W Bledsoe N 06/25/01: The excavator in this photograph is trying to tie the streambank into the culvert. A concrete wall was constructed to armor this steep bank out of material unearthed during the excavation.
Bridge W Before W 06/25/01: This west view before photograph shows the raised streambank and the reed canary grass.
Bridge W Restored W 06/26/01: Taken from the same location as the previous photograph, the gradual grade of the new streambank is quite evident. Also present is a row of coir logs highlighting the location of the toe of the slope.
