1 STORY MILL ECOLOGICAL RESTORATION PHASE I CONSTRUCTION PHOTO JOURNAL SUMMARY BOZEMAN, MONTANA prepared for 111 South Grand Ave Bozeman, Montana January 2015

2 This photo journal provides a summary of pre- and post-construction photos of the Story Mill Ecological Restoration Project. Unless otherwise noted, these photos were taken by RESPEC staff. The photo progression is organized by location, corresponding to the time when construction activities occurred. This summary document is a condensed version of the full photo journal. The photograph numbers correspond to the jpg file names that accompany this photo log. The pre-construction photos presented herein represent select Phase I construction sites throughout the project area and not an all-inclusive catalog of the pre-construction condition of the entire site. This Phase I construction photo journal is intended to be updated once Phase II construction is complete.

5 Bozeman Creek Backwater Slough Bozeman Creek has a history of encroachment and the South Parcel presents an opportunity to interface with Bozeman Creek. The Bozeman Creek Backwater Slough was designed and constructed to provide flood storage for Bozeman Creek, restore wetland area and native plant and habitat diversity, and improve water quality by filtering nutrients through wetlands and reducing velocities allowing suspended sediment to settle. Construction of the slough consisted of several activities including: - topsoil stripping throughout the slough footprint, - utilization of that topsoil for creation of a temporary access road to reduce ground disturbance and wetland impacts, - excavation of the slough using a bulldozer and two excavators, - transportation of the excavated subgrade material with haul trucks to the North Property Fill Repository, - replacement of topsoil, - seeding with native wetland and riparian seed mixes, and - establishment of Best Management Practices (BMPs) such as silt fence, erosion control fabric, and coir logs to reduce temporary construction impacts into Bozeman Creek. The following photographs summarize construction of the Bozeman Creek Backwater Slough.

10 South Parcel Pond Naturalization and Wetland Restoration The interior portion of the South Parcel was a combination of low quality wetlands and historically filled areas. A rectangular shaped pond and ditch network acted as a drain for the site to lower groundwater and facilitate agriculture. The pond naturalization and wetland restoration activities on the South Parcel were designed and constructed to restore wetland area and native plant and habitat diversity, improve visual aesthetics of the pond to a more natural configuration, and to raise local groundwater to support establishment of additional wetland and riparian areas throughout the interior of the site. Construction within the interior of the South Parcel consisted of several activities including: - demolition of old farmhouse buildings, - topsoil stripping for proposed excavation areas, - filling and recontouring of the pond area to raise local groundwater table and provide controlled water flow out of the pond during flooding, - excavation of areas surrounding the old farm houses to be closer to groundwater levels for wetland restoration, - filling and grading of the drainage ditch that traverses the site from the pond to the East Gallatin River to raise local groundwater table, - transport of excavated material with haul trucks to the North Property Fill Repository, - replacement of topsoil, - seeding with native wetland, riparian, and upland seed mixes, and - establishment of Best Management Practices (BMPs) such as silt fence and straw wattles to reduce temporary construction impacts into adjacent surface water. The following photographs summarize construction within the interior of the South Parcel.

15 East Gallatin River Bank Reconstruction The East Gallatin River Bank Reconstruction prior to design and construction consisted of abundant broken concrete slab pieces along the bank and in the channel that did not provide intended erosion protection and in some locations exacerbated bank erosion and produced a split channel. The foreign debris was removed and the bank reconstructed to restore the East Gallatin River to a more natural and functional ecological condition. Bank reconstruction activities along the East Gallatin River consisted of: - removal of all concrete from the banks and channel, - removal of mid-channel bar and filling of split channel, and - establishment of new bioengineered bank consisting of fabric encapsulated soil lifts and willow cuttings. The following photographs summarize bank reconstruction activities along the East Gallatin River.

20 Triangle Parcel Floodplain Restoration The Triangle Parcel contained several design elements to restore floodplains and provide a bioengineered streambank to replace approximately 200 of concrete slab pieces lining the bank. Immediately adjacent to the concrete slab lined bank was a large car park structure. The stream was deeply incised and had no floodplain because of historic filling activities. Hydraulic modeling confirmed the East Gallatin River 100yr flood event was completely contained within the banks at this location. Restoration on the Triangle Parcel included removal of foreign debris lining the streambank, excavation of floodplain areas to provide flood attenuation and water quality improvements, provide a stable but deformable streambank, and to restore wetland area and native plant and habitat diversity. Floodplain restoration and bank reconstruction along the East Gallatin River on the Triangle Parcel consisted of several construction activities including: - removal of all concrete and other foreign debris from the channel and banks, - installation of a temporary access bridge to facilitate excavation of the west floodplain area, - excavation and grading and foreign debris removal of the west floodplain area, - establishment of the east bank consisting of fabric encapsulated soil lifts and willow cuttings, - excavation and grading and foreign debris removal of the east floodplain area, - excavation of former gravel parking areas, - covering of excavated areas with topsoil, - seeding excavated areas with wetland, riparian, and upland seed mixes, - installation of erosion control fabric on all disturbed surfaces, and - willow stake plantings throughout the west floodplain area. The following photographs summarize floodplain restoration and bank reconstruction along the East Gallatin River on the Triangle Parcel.

29 East Gallatin River Riprap and Trash Removal The East Gallatin River contained sidewalk rubble, old machinery and trash embedded in the channel and streambanks along its 2,460 ft reach through the project area. These foreign objects were excavated from the channel, banks, and floodplain areas to restore the natural fluvial processes, important for keeping the stream in a functional balance with its environmental conditions. By restoring these natural processes, the stream will once again be able to scour pools and create spawning and rearing habitat. Cleaning the bed and banks along the East Gallatin River resulted in removal of a variety of debris including: - concrete from the banks and channel - riprap historically placed to lock the river in place - foreign materials such as car bodies, old boilers, and other random metal objects. The following photographs summarize debris removal along the East Gallatin River.

37 North Parcel Fill Repository All excess excavated material was transported and stored at the North Parcel Fill Repository. It was estimated that approximately 11,000 cubic yards of material was transported to the fill repository during Phase I construction, with an additional 4,500 cubic yards of material to be excavated during Phase II. Once all the fill from Phase I was transported to the site, the pile was graded to a gentle slope and concrete debris was stacked and fenced off. Additionally, all concrete debris removed from the stream is temporarily being stored until Phase II when it will transported offsite. All metal was hauled offsite and recycled.
