Subsequently, 24 vegetation plots, 18 stream cross sections, and 3,600 feet of stream longitudinal profile were monitored for a period of 5 years to track project condition and evaluate success. Based on year -5 data collection, the vegetation plots averaged 470 planted stems per acre which exceeds the year-5 success criteria of 260 planted stems per acre. Repeat surveys of stream cross sections document stability of channel capacity with only subtle changes related to filling or scour, mostly in pools units. Similarly, repeat surveys of the Unnamed Tributary I longitudinal profile document maintenance of thalweg heterogeneity and as-built channel grade. Channel stability was documented along with multiple bankfull events per year along the project. Stage monitoring sites 13132 and BD3 recorded bankfull events in 2 or more separate months during 2009, 2010, and 2011. Year-5 stream visual stability assessment indicated that all categories (riffles, vanes, rootwads, etc.) rated at or above 96% successful. Goals and Objectives The speck goals for the Beaverdam Creels Restoration Project were as follows: • Preserve /Restore/Enhance 15,806 LF of stream channel. • Create geomoiphically stable stream channel and floodplain conditions along UT1, UT2 and their associated tnibutaties within the Beaverdatu Creek watershed. • Improve the local hydrology through increased groundwater recharge, groundwater storage; and hydrologic connectivity between the channel and the adjacent floodplain. • Improve water quality in the Beaverdam Creek watershed by increasing dissolved oxygen concentrations and reducing nutrient and sediment loads. • Improve aquatic and riparian terrestrial habitat through improved hydraulic and biologic diversity.

The final vegetative success criteria will be the survival of 260 5 -year old planted trees per acre at the end of year five of the monitoruig period. The approved Mitigation Plan requires the following criteria be met to achieve stream restoration success: Bankfidl Events: Two bankfull flow events must be documented within the five -year monitoring period_ The two bankfull events must occur in separate years. • Cross- Sections: There should be little change in as -built cross - sections. If changes to channel cross - section take place, they should be minor changes representing an increase in stability (e-g., settling; vegetative changes, deposition along the banks, or decrease in widtiv'depth ratio)_ Longitudinal Profiles: The longitudinal profiles should show that the bedforrn features are remaining stable (not aggi -ading or degrading). The pools should remain deep with flat water surface slopes and the riffles should remain steeper and shallower than the pools_ • Bed Material Analysis: Pebble counts should indicate maintenance of bed material. • Photo Reference Stations: Photographs will be used to subjectively evaluate charnel agWadation or degradation, bank erosion, success of riparian vegetation and effectiveness of erosion control measures. Photos should indicate the absence of developing bars within the charnel; no excessive bank erosion or increase in channel depth over time, and maturation of riparian vegetation.

EEP Recommendation and Conclusion Based on 5 years of stream morphologic and riparian vegetation monitoring data it is apparent that the Beaverdam Creek stream project has performed successfully. Stream and vegetation components have met success criteria stated in the project mitigation plan as there has been little change in channel capacity, slope, or riffle particle caliber, and vegetation plots have exceeded 260 planted stems/acre when averaged. Additionally there have been numerous bankfull flow events across numerous years during the monitoring period. Based on this documented performance EEP considers the project successful and proposes it for regulatory closure with 13, 534 stream mitigation units. Contingencies There are no project closeout contingencies at this time.
