NB-1: Environmental Stewardship Stream Restoration Site Corridor 1 and Corridor 2

This document contains summaries of the existing conditions and proposed restoration concepts for several sites along the North Branch. Site NB-1 is located on public property and experiences bank erosion and stability issues. The restoration objectives are to reconnect the stream to its floodplain, reduce erosion, enhance the riparian buffer, and improve habitat. For NB-2C, located in Cashell Manor, the objectives are similar: reconnect the stream, reduce erosion and flooding, and enhance habitat. For NB-3, made up of two reaches on private property, the objectives are the same as the other sites.
