Dear Mr. Hartmann: Colorado River Engineering, Inc. (CRE) has reviewed the proposed stream restoration plans prepared for Main Elk Creek Ranch as outlined in the attached Report entitled "MAIN ELK CREEK RANCH AQUATIC HABITAT IMPROVEMENT PROJECT, SPK -2017-00295, Main Elk Creek, Garfield County, Regional General Permit 12 Application, August 8, 2017". The report was prepared by Five Rivers, Inc. and Claffey Ecological Consulting Inc. as part of a permit application to the US Army Corps of Engineers. The stream improvements will occur along a 6,200 -foot reach of Main Elk Creek located approximately 6.5 miles northwest of the Town of New Castle. The improvements are located within three parcels owned by the Ranch (PIN's 2125-021-00-188, 2125-012-00-100 and 2125-024-00-002). One home and several shop buildings exist on parcel 2125-024-00-002; they are elevated above any flood hazard area. The project location is not within the Garfield County Floodplain Overlay Zone District. In other words, it is outside of a FEMA mapped "Flood Insurance Rate Map" or other past studies completed in Garfield County. However, Section 3-102.A.2.b. of the Garfield County Land Use Development Code (LUDC) identifies the need to regulate "development" in unmapped areas. Research of the definition in Section 15 of the LUDC indicates that the stream restoration project could be covered under the terminology of "development" and therefore, MECR proposes to seek a floodplain permit approval from GARCO. The project improvements outlined in the attached report will restore and stabilize the creek channel and banks. CRE has worked with Five Rivers, Inc. and Claffey Ecological Consulting, Inc on similar projects and have observed that construction techniques utilized are very effective. Past projects have shown substantial improvements to the aquatic habitat and floodplain corridor. It is our opinion that a detailed hydraulic analysis for this project is not needed or warranted because there is not any proposed development related to housing or other improvements that require the determination of base flood elevations. The project proposes to have a net removal of river materials from within the floodplain areas. This, combined with removal of berms, check structures, flattening of bank slopes, and the utilization of riffle and pools will cause a reduction in floodplain extent and elevations as they currently exist. It is our opinion that the proposed project meets the purpose of the floodplain overlay requirements as identified in Section 3-102.A of the P.O. Box 1301 • Rifle, CO 81650 • Tel. 970-625-4933 COLO1DQ ENGINEERING 1KCORPORATI0 Garfield County LUDC. In our opinion, the project will improve the floodplain corridor through the property as well as have a net improvement to the water quality and aquatic habitat. Table 3-301 of the LUDC identifies that bank restoration and stabilization are permitted uses within the floodway and floodplain. Based on our review we believe the proposed work falls under an administrative review and on behalf of Main Elk Creek Ranch LLC request approval of the permit application If you have any questions, please do not hesitate to call me at 970-625-4933.

Introduction Main Elk Creek Ranch proposes a creek restoration and fishery habitat improvement project on Main Elk Creek, near New Castle, Colorado. Mr. Steve Mancini purchased the property in the fall of 2016, and retained Claffey Ecological and Five Rivers Inc to review the creek and develop a creek restoration plan, which we completed in the spring and early summer of 2017. The creek channel and adjacent riparian communities have been impacted by historic grazing and a recent major flow event combined with upstream channel work, and work in the creek by previous property owners. The applicant will continue ranching operations, and build a home on the property. Mr. Mancini wishes to restore the creek channel to a natural condition, improve aquatic and riparian habitats, and improve the fishery. The ranch includes approximately 1 mile of Main Elk Creek. We have submitted an application for a separate property, Meadow Creek Ranch, that adjoins this ranch downstream, and that work is similar. We request authorization of this project under Regional General Permit 12. We met with Colorado Parks and Wildlife, Aquatic Biologist Ben Felt on July 28 to review the project, and have provided him a copy of this application. We hope to have the letter from CPW to you shortly. Five Rivers hopes to start the project in late August of this year and complete the work the work this fall. The client may not complete the work in Reach 2 described below in 2017. II. Applicant Mr. Steve Mancini Main Elk Creek Ranch 42600 R.

Project Area Description Sections 1 and 2, Township 5 South, Range 91 West, of the 6th principal meridian, Garfield County, Colorado Downstream Limit: 39.639961, -107.574360 Upstream Limit: 39.650420, -107.561404 The project area is located at 6000 to about 6100 feet above msl in Garfield County approximately 4 miles NW of Newcastle, Colorado. Elk Creek is a primary tributary of the Colorado River, and drains the south side of the Flat Tops including Clinetop Mesa and Deep Creek Point (See quad Copy attached). Between the higher elevations of the Flat tops and the project area, Main Elk Creek flows through a steep narrow limestone gorge or canyon. The creek leaves the canyon approximately 2.5 miles upstream of the project area. The ranch includes approximately 1 mile of stream corridor. BLM lands adjoin the ranch on the east and west, and Meadow Creek Ranch adjoins the southern or downstream boundary. Upstream is a private land owner. Land use in the project area is primarily agricultural. Upstream of Main Elk Ranch the land use changes to small properties and newer homes along the creek channel up to the bridge 1 Main Elk Creek Aquatic Habitat Improvement Project Meadow Creek Ranch for the Clinetop Road. There is a large land holding above that and then public land in the canyon. Main Elk Creek Ranch has an existing house and shop buildings. The morphology of the project area is fairly narrow valley with steep hillslopes rising from the valley floor. The channel is entrenched within the first floodplain terrace and multiple terraces occupy the valley bottom. In locations the valley floor is irrigated hay meadow and or pasture, and sagebrush grasslands in areas not irrigated. In narrower sections of the valley bottom is cottonwood riparian communities mixed with oakbrush. The hillslopes are either oakbrush communities or pinyon juniper woodlands, interspersed with sagebrush. On Main Elk Creek Ranch stands of Blue Spruce occur in the riparian areas. Debris flow channels are present entering the ranch. Wetlands are restricted to riverine systems along the creek channel and are limited in width in many locations or not present due to eroding banks, and or past rock riprap work. In the upstream portions of the ranch, a large willow wetland is present in what be an old channel meander. This system appears to be fed by a diversion from the creek but may be an older meander. Water quality appears to be good in this drainage, although we expect that late summer temperatures are not conducive for trout due to irrigation diversions. The watershed above in the canyon is limestone (CNHP Garfield County Report), so water chemistry could be very good for trout fishery. Discussions with Ben Felt the CPW biologists indicates large numbers of brown trout were sampled downstream of the Ware and Hinds irrigation diversion (several miles downstream of this property) during the fall of 2016. Trout Unlimited and the state have an agreement and permits in place to construct a fish bypass through that diversion structure. Channel Description The channel is divided into two reaches, Upstream and Downstream using an existing bridge over the creek as a dividing point. The Upstream Reach is approximately 3,690 linear feet and is primarily a Rosgen C4 stream. The downstream few hundred feet of Reach 1 may be a Rosgen B4 stream. Grade control for this reach is a massive debris flow which crossed the entire channel and created grade control just downstream of the bridge. The debris flow channel entered the valley bottom form the west. Channel gradient is about 1.5 percent and the channel is slightly entrenched into the first terrace. The D-50 varies by location but is generally 6-8 inches. Pools, riffles and point and lateral bars are common features throughout and the streambanks vary by location. In some locations they are fairly well vegetated, in others they are eroding soils. Large rock riprap has been used in several locations, and in one concrete blocks line the bank. One short section of the bank is very old car or truck bodies. Generally pools are not deep except in a few sections where enough scour is maintained to create pool depth. (refer to Design Sheets 1-5 for Station numbers). The channel has high alluvial terraces on the left bank (south) and the abandoned floodplain terrace on the left bank is elevated well above (20-30 feet) the creek channel in many locations. The right bank or north is much lower and the channel is generally in contact with the floodplain except where man-made berms disconnect. 2 Main Elk Creek Aquatic Habitat Improvement Project Meadow Creek Ranch Two of the main elements of this reach are high banks on 2 meanders. The first is at the very upstream end of the project on the left descending bank (Station 1+00 to 2+00). This bank is a large vertical loose soil eroding bank (possibly gypsum type of material with a few large conglomerates) and the channel meanders into this bank and constantly erodes soil during peak flows. A fairly large major collapse is possible and, at the least, it adds fine sediments that impact the aquatic environment. The second tall bank starts at Station 19+00 down to Station 22+00. The left descending bank is a high alluvial terrace that was fairly vertical prior to high water in 2011. The bank eroded severely with approximately 60 feet of bank removed in the downstream section. We are not sure what caused this erosion but it could have been a large number of trees lodged against the bank at the downstream end of the meander, or simply a major channel obstruction (tree) that is no longer present. A floodplain berm just upstream of this bank on the right descending bank (Station 15+00 to 17+75) likely contributed as it does not allow flows above a bankfull discharge to reach the large floodplain meadow on the right bank. We refer to this meander as the big bank. Mr. Mancini intends to build his home on the alluvial terrace above this bank in an oak brush community and smooth brome sprinkler irrigated hay field. The previous property owner repaired the stream bank in this meander using large rock riprap on the upstream end, and a series of rock vanes (upstream angled). The work remains stable and the rock vanes have developed riverine wetlands between the vanes. Rock was stacked outside of OHW between the vanes, and the riprap upstream has an unusual amount of rock above OHW. Gypsum (?) bank at upstream end- Station 1+00 3 Main Elk Creek Aquatic Habitat Improvement Project Meadow Creek Ranch The big bank (July 2017), looking downstream along riprap, Station 15+00 Downstream of the big bank the channel has excess bedload likely from the 2011 erosion event and a number of mid channel bars that exacerbate the bank erosion. There are three rock drop structures (predate 2011 work) in the downstream portions of Reach 1 that have contributed to the mid channel bars as bedload builds up behind the structures. The drop structures are collapsing or have filled with bedload on the upstream side. Reach 2 is downstream of the bridge and is approximately 2,220 linear feet. Reach 2 is Rosgen B3, and is more deeply entrenched into the floodplain than reach 1. Gradient is steeper at about 2.5 % and steeper in locations, and the substrate is much larger. A D-50 would be about 12-16 inches but the D-84 is 18- 20 plus inches. Meanders are significantly less than upstream and the creek would not flood the adjacent hay meadows even in a major flood event. Large rock formations (truck size and larger are common on the left descending bank. The stream banks are not eroded as they are well armored with large natural rock. The reach is series of pools, short riffles and runs but the pools are shallow as the flow does not scour the large rock in the pools. The streambanks are mostly well vegetated with some willow, and cottonwood trees and saplings. The upstream portions contains oakbrush and Douglas fir on a steep bank with some blue spruce. We found a USGS gage station just downstream of the property on Meadow Creek Ranch. The gage is no longer active and appears to have recorded only from 1991 to 1998. I checked with USGS for additional data and none was available. The table below shows peak flows from that time period with more than 1,300 cfs recorded in high water of 1997, and two other high flows about 1,200 cfs in 1993 and 1995. 4 Main Elk Creek Aquatic Habitat Improvement Project Meadow Creek Ranch ZUSGS USS 09086470 MAIN ELK CREEK NEAR NEW CASTLE, CO. 1300 a) a) 1200 u = 1100 C 1000 k IDC O 4 t.

Purpose and Need The purpose and need of the project is to improve aquatic habitat in Main Elk Creek and stabilize the stream channel in Reach 1, and improve habitat for adult fish in Reach 2. The creek has been impacted by agricultural activities over the years including work upstream of the property, and lacks suitable habitat components for good fishery. We have observed some fish in the channel in mid march, but a recent walk through with CPW fisheries biologist observed very few adults, although we did observe this year's fry. The fishery and aquatic ecosystem are impacted by irrigation diversions which create low flows in late July through mid September, raising water temperatures. Increasing pool depth overall, and maintaining scour in those pools with constructed or enhanced riffles will help with this impact. Narrowing the channel with lateral bars will restore a better width depth ratio. In the recent past the property was managed better than historically and excess grazing was not an issue, however the previous owners completed some bank armoring that needs correction to improve aquatic habitat, and large rock drop structures that need to be converted to riffles. Reach 1 has also been affected by the bank erosion in the reach and in -stream channel work upstream, with ongoing excess sediment deposition from gypsum bank at the upstream end of the ranch. Mid channel bars have formed creating over wide channels in some locations and the bars also exacerbate further bank erosion. Three rock drop structures in the downstream portion of Reach 1 have deteriorated and have filled with bedload upstream creating a 60-70 foot wide channel that is a few inches deep in mid July. In various locations in Reach 1, streambanks will 5 Main Elk Creek Aquatic Habitat Improvement Project Meadow Creek Ranch be restored: by removing large rock and or concrete blocks, or old car/truck bodies, and in some locations repairing actively eroding banks. The channel lacks depths in most pools and riffles are not formed enough to maintain scour. Mid channel bars will be removed and lateral bars established to decrease width/depth ratios. Reach 2 is a much steeper gradient and impacts from upstream work and massive bank failures are not as apparent except in pools and in a few over wide sections. The pools are shallow and The channel and existing riffles do not appear to have power to maintain scour and pool depth. The project uses natural channel design and techniques Five Rivers and others have employed throughout the west. Natural functioning riffles are used to control grade and maintain scour in pools excavated in the correct locations. Pools provide adult habitat in winter and in summer low flows, a temperature refuge. The riffles and the constructed lateral bars help to narrow the channel in locations to improve the width/depth ratio. Eroded stream banks are stabilized and revegetated with several bio -engineering techniques. A series of log jams, similar to those present, are created to provide scour points and pool depth, protect eroded banks, add large woody debris and provide juvenile refuge habitat. V. Proposed Work and Design The proposed stream work plan view is shown on Sheets 1-5, and the details (typical x -sections and profiles) shown on the 3 additional Figures 1-2. Channel survey from Bookcliff Survey was completed in May, and the cross-sections can be provided. That survey will be used by an engineer to work with County on floodplain management issues. The excavation and fill quantities by stream station shown by station, and per habitat type are included in Appendix A. The pools are shown in blue and the cubic yards for pools is all excavation. Riffle, and lateral bars, bank toes and coir banks features are where there are discharges of material below ordinary high water. That material is generally river cobble excavated at the pool sites. In total 26,310 square feet of channel area would be filled (0.60 acre) would be filled with about 1,370 cubic yards of material. Note, Appendix A does not include 110 cubic yards of large rock (2-3 foot diameter) used as riprap on the 220 feet of loose soil bank at Station 1+00. Approximately 1,261 cubic yards of material would be excavated from the channel at pool sites, and reused in riffles, lateral bars and coir banks. No large rock is added to the channel but existing large rock in drop structures is lowered into the substrate. Five Rivers Inc has developed the proposed plans (attached) for this project, and Claffey Ecological has assisted in the field work for design. Matt Weaver of Five Rivers has extensive experience in cobble bed river restoration projects in Colorado, Montana, Wyoming and New Mexico implementing those projects in the field. Mr. Weaver and/or Mr. Michael Claffey will be on site during all phases of construction, and heavy equipment operators experienced with river restoration will be completing the work in channel. All work proposed is below ordinary high water of Main Elk Creek, with the exception of few spots where we would slope back eroded stream banks. There is no proposed discharge of dredge or fill material in wetlands. We do not provide a delineation of OHW as all work proposed is below ordinary high water, and acreages and cubic yards discharged shown in Appendix B are 6 Main Elk Creek Aquatic Habitat Improvement Project Meadow Creek Ranch all below ordinary high water of the stream. In a few areas, we slope back a vertical stream bank that would not be below ordinary high water, and the cobble harvest area is in uplands. We also remove a cobble dike in Reach 3 which is above OHW. The entire project area is a series of riffle and pool complexes, albeit not stable. Overall design elements: The project will create stability and improve trout habitat by creating a series of riffles, pools, and lateral bars in channel and stabilizing eroding stream banks with bio -engineering techniques. Large rock structures are not proposed, and the in -stream work is basically " actual manipulation of the active channel itself in an effort to improve fish habitat" (from GP 12 Scope of Work). In this case, the design also attempts to narrow the channel where it is overwide, but also to create better habitat for the late summer low flow conditions created by irrigation withdraws. In addition, bio -engineering techniques are used to restore eroding streambanks, and on this project selective replacement and modifications to one large rock riprap bank completed the previous owners. Riffles are natural features that provide grade control in a stream, and help scour pools. Five Rivers creates riffles at grade and excavates the pool downstream to create scour points. The riffles are constructed at the appropriate length, width and grade to remain stable, however, they do move — growing and eroding over time as the channel changes. Riffle are generally constructed with the largest cobble available (D84). Riffles are riffle grade breaks that help maintain water surface elevation upstream as well prevent downcutting. Pools create adult habitat for overwintering and general, but in this case also provide for refuge areas during late summer low flows. Pools are excavated to 3 to 4 feet depths at summer flows. The lateral bars help to reduce overall width in areas where the width -depth ration is off due to mid channel bars and bank erosion. The proposed work of returning the channel to natural configuration of pools, riffles and lateral bars, and the appropriate width will help maintain stability by moving bedload through a reach and/or trapping it on lateral bars as a stable channel would function. The riffles and lateral bars are low profile, developing a narrower channel at low flow conditions but leaving plenty of channel capacity for high flow events. Bank erosion is treated with two techniques — bank sloping/cobble toe and a coir lift. Coir banks (Figure 1) are soil encapsulated lifts constructed with coir fabric (Bio D 90) and supported with a large cobble substrate to prevent scour. The coir lifts are filled with cobble and soil, seeded and under -planted with willows. The containerized willows are placed between the cobble toe and the first coir lift. The lift is anchored into an anchor trench on the end away from the channel. Weaver has extensive experience in stalling these bio -engineered banks, and the coir is anchored into the upland edge in a trench, with willows planted under the fabric as shown. The bank is built out in the channel to help narrow the channel a little in these sections (where needed), and the vertical banks are sloped bank, topsoiled seeded and covered with erosion control fabric. Bank sloping (Figure 2) is used in areas with lower stream velocities, and involves excavating back the vertical bank and building a toe of bank with 6 to 12 inch stream cobble embedded into the channel for scour protection. Containerized willows and some transplants are installed above the cobble toe, and the slope of the bank topsoiled, seeded and covered with erosion control fabric. 7 Main Elk Creek Aquatic Habitat Improvement Project Meadow Creek Ranch Due to excess bedload deposited from bank erosion and events upstream, there will be a net excavation or removal of material. Any material removed is hauled to an upland site on the upper alluvial terrace where the Mancini's intend to build a home. It will be used as driveway material or fill. Any material removed will be placed in uplands, and often the material is placed temporarily and used as cobble toe protection for bank restoration or in riffle grade breaks On Sheets 1-5 all work in Blue is done by the stream restoration contractors, and work in red is done by the ranch manager with a ranch track hoe as it generally involve normal excavation work, and not forming stream habitat features. Five Rivers will manage all work. Left bank is left descending bank and right bank is right descending. Work Description Reach 1 Starting at 1+00, a large rock riprap would be placed at toe of eroding hillside to prevent further erosion. In addition, a large amount of bedload has dropped out in this reach over the years as the bank erodes and the channel is wider. That material has formed a high and over wide lateral bar. In addition, the previous owners left a pile of cobble on the bar that intended to place against the eroding bank (they apparently placed cobble there every so often as it simply eroded away). The lateral bar would be excavated to increase cross-section in this area, and the material hauled off, creating a more appropriate slope on the bar. Just downstream of this at Station 4+00 plus or minus we construct a lateral bar on the left descending bank to narrow this overwide channel section. We also remove concrete blocks used for bank protection on the left bank, and lower the riffle crest approximately 1 foot in elevation and reconstruct as a natural riffle of the same length. The height of the riffle is adjusted to match the constructed lateral bar and reduce erosion against the left bank. From Station 5+00 to 7+00 is a series of riffles and two pools. At Station 7+00 to 8+50 we remove the diversion and ditch in the channel and build a run. From 7+00 to 9+00 on the right bank (RDB) the upstream section is a cobble toe and willow planting. At the downstream end we remove a concrete block stream bank and build a soil encapsulated lift. Between 9+00 and 10+00 is an exisitgn ford of the creek, no work is proposed. From 10+50 down to about 14+00 is a series of riffles and pools with a lateral bar constructed to narrow the channel. At 14+00 we propose to stabilize a headcut developing where a tributary enters Main Elk Creek with about 20 cubic yards of large angular rock. The rock is anchored into the bed of the tributary to prevent further channel incision. From 15+00 down to 18+00 we remove three partial car bodies from the bank, construct three small riffles and three pools. From 18+25 down to about 22+00 is the big bank that eroded severely in 2011. As described above, the previous owner did some large rock riprap and constructed upstream pointing jetties or rock barbs to repair the bank. This work was done between August 2011 and June 2014 by the ranch manager, and as far as we know, a 404 permit was not obtained. We plan to leave the rock barbs in place but lower the overall height (remove a few rocks) to improve the appearance, but they seem to be functioning well. At the upstream end of this reach a riffle and pool are constructed, and then an existing riffle is re -enforced at 19+50. The sandstone riprap bank is very high along the left bank and extends for about 320 linear feet. Five Rivers will selectively remove rocks up high that serve no erosion protection 8 Main Elk Creek Aquatic Habitat Improvement Project Meadow Creek Ranch purpose, and replace rocks along the channel with more natural river rock. There would not be a net fill of material but removal and replacement of rock. At the downstream end, an exisitgn riffle is re -enforced to help maintain scour in the pool excavated downstream. In addition, between station 19+00 and 22+00, the applicant will slope back the big bank to reduce the slope to a more stable angle. All of this work is in uplands and is 30-40 feet higher than the river at the top and would extend to no closer than 15 feet above the river at the lower end. It is not part of the river project, and has no direct value to the aquatic enhancement project except long term prevention of a major soil collapse into the creek, if the bank ever erodes again. At the downstream end, an exisitgn riffle is re -enforced to help maintain scour in the pool excavated downstream. From Station 23+00 to 25+00 a soil encapsulated coir left is constructed on the right bank to repair eroded banks and remove large rock riprap. A riffle and pool are constructed as well in this reach. From 25+00 down to 26+50 a cobble toe and willow plantings are used on the eroded bank, and riffle and pool constructed. From 26+50 downstream to about 38+00 a series of pools, riffle grade breaks and lateral bars are constructed to improve habitat conditions and reduce the width of the channel. At 30+25 and 31+75 the two large rock drop structures is converted to a riffle grade break by lowering the large rock into the bed and adding cobble. At 33+00 to 34+00 the eroding stream bank is repaired using a soil encapsulated lift, and floodplain berm is removed at about 34+75 to 35+25. At station 38+00 to 39+50 tow large rock drop structures are rebuilt and lowered to function as riffles and two pools excavated. Reach 2 For Reach 2 the work proposed is a series of riffle grade breaks constructed or re -enforcing exisitgn riffles, pools excavated for late summer and winter habitat, and two lateral bars constructed at the downstream end of the project to narrow an over wide section. Plan sheets 4 and 5 describe the work in detail. VI. Terms and General Conditions Item 5 of information required includes pre -project photos at fixed GPS points depicting the physical setting to be compared with post project photos. These pre- project photos are included with GPS location, and bearing. Photos will be submitted from the same points and bearing with each monitoring report. A representative selection of riffles, pools and lateral bar work areas will be selected within each reach, and most of the bank restoration sites. The project has or will comply with the 30 general conditions of RGP 12. Endangered Species Act and Section 106 are discussed below as well as sediment control during construction. Endangered Species Act: I did a search on the US Fish and Wildlife Services' web site for listed species and their habitat in Garfield County and then specifically the project area. The project area is listed as potential habitat for Ute Ladies' Tresses (Spiranthes diluvialis), and 9 Main Elk Creek Aquatic Habitat Improvement Project Meadow Creek Ranch further checking with Ecological Services Grand Junction office (Dara Taylor, personal communication June 2017) revealed the project area was in the Section 7 survey area for Spiranthes. Ms. Taylor indicated I could provide a rationale for why surveys for this plant should not be required, and they would consider that rationale. On July 3, 2017 I submitted a letter report to Ms. Anne Timberman of the Ecological Service office providing a rationale of why surveys were not required for this species and copied Mr. Travis Morse of the Western Colorado Regulatory. The letter briefly described the project area and the restoration project, and explained that no proposed work would occur in possible habitat for this species. The FWS responded on July 7 by email from Dara Taylor that Spiranthes surveys would not be required, and they copied Mr. Morse on that email (copy enclosed). No other listed or candidate species occur in the project area or whose habitat would be affected by the project. Section 106 of the National Historic Preservation Act: It does not appear that any cultural resource sites would be affected by the project. To facilitate review for the Corps we have requested a Class 1 Files Search through Metcalf Archaeology of the river corridor in the project area (including Main Elk Creek Ranch upstream). That report is included in Appendix B. The project area is an active fluvial environment and little if any cultural resources could last within the active channel where we propose work. We did not notice any cultural features during the field work for this project, and none were located by Metcalf. Sediment Control: Work in the river will generate sediment which is unavoidable. The contractors will employ techniques to reduce sediment plumes, although work of this nature has occurred in many miles of stream son the western slope with little if any measurable sediment impacts downstream. Wheeled vehicles such as trucks and front end loaders will not work in the river. It is expected only one tracked excavator will be working in the channel. If sediment plume becomes excessive, more than the creek flow can dissipate in several hundred feet, the work will stop for a duration of time to allow for absorption of the sediment. In the past that has been anywhere from 10 minutes to 1/2 hour. We do not expect major problems as there are very few clays or fine particle soils in the area, and the substrate is small to large cobble. In addition, irrigation diversions that the ranch controls will be kept to a minimum or cease while the river work is underway to keep flows high. If necessary the irrigators will irrigate in the evening and night when river work ceases. Bank restoration work by its nature can generate sediment as often the cobble and gravels have been stripped away by the erosion events, and only soil is being worked. As bank work is completed, small cobble coffer dams can be placed at the upstream end to deflect flows away from the bank while the major excavation work is underway. Those coffer dams are then moved downstream as needed, and incorporated into the next feature when the bank work is completed. Monitoring Reports: A construction report will be submitted in the fall of 2017 after the project is complete including site photographs of construction techniques, and the same photo points at GPS locations as the pre -project photos with a brief description of the site conditions. A monitoring report will be submitted after high water in the first year after construction (2018) to include all photo points submitted with pre -project photos, and include a brief description of 10 Main Elk Creek Aquatic Habitat Improvement Project Meadow Creek Ranch site depicted. A second monitoring report would be submitted after high water 3 years (2020) after construction using the same photo points and a description. VII Conclusion The proposed project will improve aquatic habitats in this reach of Main Elk Creek, and restore eroding streambanks and repair some of the exisitgn large rock work completed. The stream will be stabilized with the proposed bank restoration and developing stable riffle, pool and lateral bars, and having the channel width back to an appropriate width, and width/depth ratio. Mr. Mancini does not plan to graze cows or sheep and horses are kept in fenced corrals. We request Regional General Permit 12 authorization for the proposed work, and to authorize and maintain some of the work as described above installed by the previous owner. 11 Main Elk Creek Aquatic Habitat Improvement Project Meadow Creek Ranch ; • � r -- � :_-A-,--.y I �i\+ 2` I � �✓ 2 -'r t � � -. / J r- 5 `_ m Li 71`,-.,„ l te�I —`4-1.-.' fit `r 1 '` "�'r °c i - J1 .,, ,f I /�f I1 ; •,, �, •I , 6 w )'''''-j $ 1 1 ;Doafnsre�rtt limits 1 _.Y.� • 11 7003 `t C(- yjt Declination 7- .11 MP MN 10.33° E r SCALE 1:24000 1 MILE 1000 YARDS I 1 KILOMETER Name: DEEP CREEK POINT Date: 08/08/17 Scale: 1 inch = 2,000 ft.

Wetlands -Streams -Wildlife -404 Permitting -NEPA July 3, 2017 Ms. Anne Timberman Western Colorado Supervisor US Fish and Wildlife Service, Ecological Services 445 West Gunnison Avenue, Suite 240 Grand Junction, Colorado 81501-5720 Dear Ms. Timberman: I am representing two clients on river restoration projects on Main Elk Creek in Garfield County, and we will be applying for a Regional General Permit 12 from the Corps in the near future. These are adjoining properties, and cover in total about 6 miles of the creek. The upstream property contains about 1 mile of creek corridor and is called Main Elk Creek Ranch and the downstream property is about 5 miles of creek corridor and is known as Meadow Creek Ranch. I spoke to you briefly about this project, and in more detail with Dara Taylor of your office. Dara responded by email after reviewing quad location map I provided that the projects were in the Section 7 consultation area for Ute Ladies'Tresses (Spiranthes diluvialis), and that we would need to provide a rationale for why habitat is not present to avoid survey requirements. I hope to provide that rationale in this letter report. Elk Creek is a tributary to the Colorado and drains the southern portion of the Flat Tops. The stream is generally high to moderate gradient, with small to large cobble substrate and a bankfull width of about 30-45 feet. The stream and riparian habitats are heavily impacted by grazing and stream flows are affected by irrigation diversions in the late summer. Highly eroded stream banks, mid channel bars and over wide sections of channel are common. Water quality appears to be good. The restoration project has been designed by Five Rivers, Inc and includes creation of a series of pools, riffles and lateral bars, as wells as restoring eroded stream banks to re-establish a natural self sustaining channel and improve aquatic habitats. Plans include extensive riparian fencing to keep cows and sheep out of the riparian habitats, and better management of water use. We have 4000 native willows shrubs growing in a native plant nursery to be used in bank restoration. Spiranthes diluvialis (SPDI) occurs in moist meadows associated with perennial streams, floodplains, and oxbows, seasonally flooded river terraces, sub -irrigated or spring fed abandoned stream channel. It has also been found in irrigated meadows, excavated gravel pits, roadside barrow pits, reservoirs, irrigation ditches, berms, and other human modified wetlands (FWS ECOS website). In Colorado, SPDI was primarily found on the front range and along the Yampa River in the northwest corner in Moffat County, but more recently found in the Roaring Fork 970-640-3783 mclaffey@acsol.net valley in Garfield County. Colorado Natural Heritage Program (CNHP) lists the habitat as along streams and open areas in cottonwoods, moist meadows on floodplains in the vicinity of abandoned stream channels and meanders where vegetation is not too dense or overgrown (CNHP website). Fertig et al (2005 — Rangewide Status Review of Ute Ladies' Tresses) report the habitat for SPDI as the same conditions but also noted that most populations occur in habitats that were not overly dense or heavily grazed. The main elements of SPDI habitats are they occur in wetlands, either natural or man-made. The associated plants found with SPDI are wetland species. For these two river restoration projects, the work will occur in the active channel of the river, or on severely eroded stream banks, and no work is proposed in wetlands. Work is proposed in the upper 3 miles of the stream. The downstream sections of Meadow Creek Ranch would be completed later. The irrigated meadows near Main Elk Creek are very dry, produce one hay crop in spring, and do not contain wetlands or irrigation return flow wetlands. The surrounding habitats are oakbrush and pinyon juniper. Oakbrush is often a riparian plant in some locations. The soils are well drained, and the main species in the irrigated meadows are smooth brome, orchard grass and wheatgrass. There are not any abandoned stream channels or oxbows in the project area. The upstream property (main Elk Creek Ranch) has a large wetland area fed by irrigation water but the habitat is dense willow cover and no work is planned in or near these habitats. There not any sub -irrigated meadows or springs where we plan to work. The irrigated meadows are on higher terraces and based on limited irrigation water in mid to late summer, and the arid conditions, sub -irrigated wetlands simply do not occur. Access points are dry meadows at eroded banks (we repair the bank as we leave that reach of stream), existing ranch roads, and drier upland areas near the creek. This is a restoration project, and any vegetated wetlands or riparian habitats are generally avoided as it is difficult to establish this type of community during restoration, and we are also under review by the Corps for wetland impacts. A track hoe enters the creek and typically stays within the active channel. Pools are excavated and the material excavated used to create riffles to maintain scour in the pools. Lateral gravel bars are created with the excavated material in reaches that are over -wide due to bank erosion to also maintain scour in the pools and runs. The bar is formed in the open water of the overwide section to narrow the channel and maintain scour. Heavy equipment will not be driving through wetlands to access the channel, and there are not any out of channel disturbances in wetlands or riparian habitats proposed. The heavy equipment operators specialize in this type of work, and are well aware of the restrictions and a project manager is on site at all times. The downstream sections of Meadow Creek Ranch include a more meandering stream channel with dense willow wetlands (Salix exigua) in riverine conditions. There locations in this downstream reach were mid channel bars and erosion as has created back water areas, and low gradient side channels across point bars. These areas are left as is because they create excellent refuge habitat for juvenile and YOY trout, improve diversity of the aquatic ecosystem, and also because the Corps and CPW (Corps solicits CPW comments on all GP 12 applications) would not generally approve impacts in these types of habitats. There is also not a need to work in these areas and the heavy equipment work is costly. 2 There is one area where we currently plan to harvest some whole live willows clumps to use in restoration of the eroded stream bank in this reach. This is a dense coyote willow stand (Salix exigua) with closed canopy of willows and is not SPDI habitat due to canopy closure. Approximately 30 clumps would be removed for use in stabilizing the stream bank. We do not believe that habitat for this species is located in the areas we intend to work for this restoration project. There are not any permanent fills or removal of vegetated habitats that would affect SPDI as work occurs in the live stream or on eroded stream banks. I will provide a disc with the plans or send them electronically if google drive would work. We request that survey requirements for SPDI are not required for these two projects, and that your office either notifies me, or the Corp of Engineers, Grand Junction office (Mr. Travis Morse) that surveys are not required. Thank you for your time and consideration. Sincerely, Michael Claffey Claffey Ecological Consulting, Inc.

The purpose of this study is to provide information to Claffey Ecological Consulting, Inc. and its client with information on known cultural resources in the project area, as well as a summary of cultural resource inventory that has already occurred. The majority of this project is located on private lands; however a tiny part of the corridor extends onto lands administered by the Bureau of Land Management, Grand Junction Field Office in Section 2. The information in this report will be used for future project planning. It is our understanding that this project will require federal agency oversight (USACE, and possibly BLM) for permitting when it proceeds. The proposed 400 foot wide corridor for restoration along Elk Creek is shown in the attached Maps 1 and 2, prepared by us from kmz files provided by you, showing the location of the proposed project area relative to the footprint of previous cultural resource inventories conducted. A second set of maps, Maps 3 and 4, shows the locations of previously recorded cultural resources near the project footprint. Those resources within the 400 foot corridor are shown in red. These maps are included in agency copies of this report only. They are for official use only and not for public distribution. Disclosure of site locations is prohibited by federal law (43CFR7.18). FILES SEARCH RESULTS A total of eight previous cultural resource inventories have been conducted within the legal sections containing the creek restoration corridor (see included table and Map 1). A large portion of the corridor was covered by a previous block inventory (OAHP #GF.R.R4) in 1978 by the UNC Office of Public Archaeology. However, in our experience, reviewing federal agencies, including USACE, require that surveys older than about 15 years be completely re -done. The other previous inventories in the project area only intersect small portions of the corridor. Therefore, we anticipate that a 100% inventory of the creek restoration corridor will be required for project permitting. (970) 328-6244 Fax: (970) 328-5623 P.O. Box 899 Eagle, CO 81631 www.metcalfarchaeology.com Metcalf Archaeological Consultants, Inc. Beyond Compliance Est. 1980 Two previously recorded cultural resources (5GF316 and 5GF401) are located within the 400 foot creek restoration corridor (Maps 3 and 4). Neither of these sites have official recommendations for eligibility to the National Register of Historic Places (NRHP). At a minimum, these sites will need to be re -visited and evaluated for eligibility to the NRHP; it is also likely that new site forms will need to be completed for them. To arrive at these recommendations, we requested and received GIS site and survey data from the Office of Archaeology and Historic Preservation (OAHP) on July 11, 2017. We also queried OAHP's online Compass database for information specific to previous inventories and previously recorded cultural resources.

In addition, there are two paleontolocial localities in OAHP's records. These include: State No. Resource Type Date Recorded NRHP Evaluation Comments 5GF313 Prehistoric Open Camp 1978 Officially Not Eligible 5GF314 Prehistoric Open Camp 1978 Officially Not Eligible 5GF315 Prehistoric Open Camp 1978 Field "Needs Data" 5GF316 Prehistoric Open Camp 1995 Officially "Needs Data" May need limited testing to make an NRHP recommendation; 92 feet from the creek 5GF348 Isolated Find 1978 Not Eligible 5GF400 Historic Agricultural Complex 1975 Field Not Eligible 5GF401 Historic Log Barn, Unknown 1977 Unknown Little information on record; 147 feet from the creek 5GF2169 Historic Habitation 1995 Officially Not Eligible 5GF2170 Historic Ditch 1995 Officially Not Eligible 5GF2569 Paleontological Bone Bed 1994 No assessment given 5GF2572 Paleontological Unknown 1996 Field Not Eligible The previously recorded resources include four prehistoric open camps, one prehistoric isolated find, one historic agricultural complex, one historic log barn, one historic habitation, and one historic ditch. In addition, there are two paleontological localities in the project area. All of the resources are outside of the planned creek restoration area, except for site 5GF316 and 5GF401, which are within the 400 foot wide corridor. Site 5GF316 is a prehistoric open camp that is officially listed as "needs data"; it is located 92 feet from the center of the creek. This recommendation indicates that an NRHP recommendation of eligible or not eligible could not be confidently made by the surface expression of the site alone. "Needs Data" sites often require limited subsurface testing to prove whether or not they retain potential for additional data and are NRHP eligible. Site 5GF401 has very little information on record in OAHP's database, but appears to be a historic log structure. It is located 147 feet from the center of the creek. It does not currently have an NRHP recommendation listed in the records. (970) 328-6244 Fax: (970) 328-5623 P.O. Box 899 Eagle, CO 81631 www.metcalfarchaeology.com Claffey Ecological Elk Creek Restoration Class I DISCUSSION AND EXPECTATIONS Metcalf, using results of the OAHP records files search, concludes that there is good potential for encountering cultural resources within the proposed Elk Creek restoration project area. Previous work indicates a moderately high site density in the area, and the margins of creeks have always been a favorable location for habitation in both prehistoric and historic times. Although one large block inventory has occurred within the project corridor and covers a large portion of the restoration area, it is too old (1978) to be considered adequate by federal agencies for cultural resource permitting. The other previous inventory within the area of potential affect only intersects the corridor in a small area, so it does not provide substantial coverage. RECOMMENDATIONS Because the proposed restoration area has not been systematically surveyed within the last 39 years, Metcalf recommends planning for a Class III inventory of the entire 400 foot wide corridor if the projects require it for permitting; or if federal funding is involved and Section 106 review is required. Furthermore, based on previous work the area appears to have prehistoric and historic site potential. Both of the known archaeological sites will need to be revisited and evaluated for NRHP eligibility. If an NRHP recommendation cannot be made from the surface expression of the site alone, limited testing might be needed to determine whether or not the sites retain research potential. For scheduling purposes, a Class III inventory of a project this size can be completed fairly quickly, start - to -end probably over the course of a month including reporting. Limited site testing to determine NRHP eligibility can be done quickly, usually within a day at each site. The consultant's report then is reviewed by the lead agency, a process that typically takes 2-4 weeks and depends entirely on the agency's staff availability and internal agency priorities. If sites are found that are known to be, or recommended to be, eligible for the National Register, the agency is usually obligated to consult with the OAHP on findings and recommendations, a review process that can take up to an additional 30 days. If there is need to conduct mitigative work—if the project is found to have an adverse effect on an eligible site, and the project design cannot be changed to avoid the site—a plan for that work is prepared, reviewed, and then accepted by the lead agency and OAHP, after which it can implemented. This can take several weeks or months. All of this usually needs to happen before any restoration work is allowed to proceed. For projects that anticipate mitigation, Metcalf recommends planning to begin the Class III inventory process as early in project planning as possible. Inventory work can begin as soon as the ground is 80% free from snow. For projects that do not end up requiring some form of mitigation, a three month time frame from initiation of cultural resource work to agency acceptance of a final report of that work, is reasonable.

Box 899 Eagle, CO 81631 www.metcalfarchaeology.com Claffey Ecological Elk Creek Restoration Class I The files search indicated the presence of two paleontological localities in addition to the cultural resources. The lead federal agency may require that a paleontology survey of the restoration area is conducted in addition to cultural resource inventory, if they judge that the area has potential for these kinds of resources. Metcalf does not have a paleontologist on staff, but we do routinely sub -contract with several paleontology consultants in northwest Colorado. We would be happy to provide this service directly if needed for this project, or provide references to Claffey Ecological.
