REMARKS: On May 24 th, 2016, Beach Hastings (USFS) conducted an inspection in conjunction with a visit by Forest Botanists, who were there to observe the emergence of Sacajawea s Bitterroot. The primary focus of this inspection was to identify spring conditions and any items of concerns from winter snow melt and spring runoff. The secondary purpose was to escort the botanists to known population areas of Bitterroot. This was the first visit to the site this year due to access and weather conditions. We traveled through much of the project site. No exploration activities took place during the 2015 operating season so no new disturbances was observed. Most of the identified maintenance needs (outlined below) is related to road maintenance and erosion control. ACTION ITEMS: Initiate follow-up site visit with CuMoCo and FS employees (Hydro & Botany) to identify areas of concern and necessary repairs and maintenance. Possible items to address: o o o Review preventative maintenance of storm water BMPs such as cleaning out sediment traps at water relief points along the roads, replacing straw waddles as needed, clean-out culverts and repair gullies in road as needed. Visit two culverts on front access road (FSR382C); both culverts were plugged and caused gullying across road. See photo #1 of lower culvert. Possible runoff improvements to the main road above the gully forming between main road and upper middle road. The gully is present in occupied Bitterroot habitat. Gully varies in width from a few inches to over 18 inches; depth varies between a few inches and 16 inches deep. I is believed this feature was the result of a series of major thunderstorms in August of 2014 that caused road damage and debris flows throughout the Forest. While the presence of vegetation in the feature would suggest it is fairly stable to normal runoff events, corrective action should occur per Page 1
recommendations of the district hydrologist and engineer. Action should occur prior to the summer monsoon season in the event of another significant rain event occurring to prevent any further down cutting. See photos #2, #3, #4. o Possible need to stabilize inside headwall road cut of Upper Middle Road. See photo #5. PHOTOS: Photo #1: Plugged and washed out culvert on FSR382C.
