The application is organized to correspond to each numbered item under Section 7-35 (b). Project Description The scope of the project includes landslide repairs on a portion of the Minnesota Bluffs LRT Regional Trail in Chanhassen, MN owned by the Hennepin County Regional Railroad Authority (HCRRA). Two areas will be repaired as part of this project – the north repair area and the south repair area. Project access will be from Highview Drive in Eden Prairie, proceeding southwest along the trail to the site, and also from Flying Cloud Drive through the Moon Valley Aggregate operated property (final access route through Moon Valley Aggregate operated property pending property owner authorization). Landslide repairs in the south repair area will include stabilizing the south slope, repairing the south culvert outlet area and constructing a new storm sewer and drainage ditch to direct water into the repaired area. Plans for redirecting the water were provided to the Lower Minnesota River Watershed District for review and comment on December 12, 2019. The response from the watershed district will be provided to the City upon receipt. Existing trail profile grades will be reduced with the embankment slopes regraded to less steep grades and finished with turf reinforcement mats. The existing damaged concrete headwall will be removed and existing riprap will be salvaged for reuse. The south culvert outlet area will be repaired with riprap, boulder cross vanes, and a stilling basin. Work in the north area will include removal of existing pipe debris, placement of riprap fill on north slope, and abandonment of the existing pipe crossing beneath the trail. Drainage will be rerouted from north pipe area via new buried storm sewer and lined drainage channel, which will discharge to the south culvert outlet area. 2 Interim Use Permit Application Item 1: The name and address of the operator and owner of the land, together with proof of ownership. If the operator and owner are different, both must sign the application. Contact Information Owner: Hennepin County Regional Railroad Authority Mailing Address: 701 4th Ave. S, Suite 400, Minneapolis MN 55415 Contact Person: Jessica Galatz, Project Manager Phone Number: (612) 348-2691 Email: jessica.galatz@hennepin.us Alternate Contact Person: Kristine Stehly, Project Engineer 2 Phone Number: (612) 348-6370 Email: kristine.stehly@hennepin.us Proof of ownership is provide in Attachment 1. Item 2: The correct legal description of the property where the activity is proposed to occur. All that part of a variable width strip of land in Sections 34, 35, 36 and 25, Township 116, Range 23, Carver County, Minnesota, being former railroad right of way. Subject to existing public roads and highways, and easements of record, if any. Item 3: A certified abstract listing the names of all landowners owning property within 500 feet of the boundary of the property described above. The City of Chanhassen provided the applicant with a list of landowners located within 500 feet of the property boundary on December 2, 2019. Refer to Attachment 2. Item 4: Specifications of the following, using appropriate maps, photographs and surveys: Full project specifications are provided in the construction design plans as Attachment 3. Draft specifications for horizontal directional drilling (HDD) are provided as Attachment 4. Once a final copy of the HDD specifications is available it will be provided to the city. a. Proposed grading plan Refer to the attached construction design plans, sheet G-08 (Attachment 3). b. Proposed stockpile sites Stockpiling will occur in the areas identified as staging areas on plan sheet G-05 (Attachment 3). There is limited space for stockpiling material on the site. The contractor will likely choose to put any excavated material directly in trucks to export from the site and stockpile temporarily stripped topsoil on site. It is likely that material will also need to be imported and stockpiled at the site within the staging areas on plan sheet G-05 (Attachment 3). Imported material will include riprap, granular filter, and topsoil. c. The physical relationship of the proposed designated site to the community and existing development. The project site is located on a portion of the Minnesota Bluffs LRT Regional Trail in the Rice Lake area just north of Flying Cloud Drive. The project will take place on Hennepin County Regional Railroad Authority property. Two repair areas are part of this project – north repair area and south repair area. A gravel pit owned by Moon Valley Aggregate is located southeast of the south repair area. There are no other residential, commercial or industrial developments immediately adjacent to the north and south repair 3 areas. Residential areas are located on either side of the trail in the northeast portion of the project area (Figure 1). The northeast portion of the trail will be used for construction access only. d. Site topography and natural features including location of watercourses and waterbodies. The trail slopes down from the northeast towards the southwest with an approximate elevation of 880 feet at the northeast access point coming down to 830 feet at the south repair area. Topography on either side of the trail is variable but generally downward sloping. Refer to sheet G-08 (Attachment 3) and Figure 2 for elevation contours within the project area. Wetlands are located on either side of the trail along the access with a small percentage located within the construction limits (Figure 3 and 4; sheets G-05 and G- 06, Attachment 3). A small wetland is located northeast of the north repair area outside of the construction limits (Figure 4). A stream channel runs adjacent to the trail from the northeast. The stream channel is outside of the construction limits at the north repair area and flows under the trail via the south culvert in the south repair area (Figure 4). No other waterbodies are located within the project footprint. The site is not within a designated floodplain (Figure 5). A Public Water Inventory basin (unnamed) is located northwest of the access at Highview Drive but is not within project limits and will not be impacted by construction activities (Figure 6). e. The description and quantity of material to be excavated. Excavated material will include soil and riprap. The total estimated quantity of excavated material is: • Excavation – common (non-contaminated material): 19,990 cubic yards • Excavation – special (contaminated soil): 2824 cubic yards The trail lowering portion of the project will require extensive excavation and some of the material on the surface is contaminated. Contaminated soil will be exported offsite to an approved waste disposal facility. No new soil will be needed as the finished grade is much lower than existing grade. f. The depth of water tables throughout the area. Refer to Figures 7 and 8 for water table depths/elevations. Depth to water table is approximately 0 to 25 feet in most of the south repair area, 25 to 75 feet along the trail and, 0 to 25 feet in the north repair area. g. The location and depth of wells and buried garbage, water and fill. There are no public or domestic wells within the project footprint, refer to Figure 8. No buried garbage or fill was identified at the site. Item 5: The purpose of the operation. The purpose of the planned work is to repair landslides along a portion of the Minnesota Bluffs LRT Regional Trail that occurred in 2014. In addition to the landslide repairs, a new storm sewer and drainage channel are proposed to be constructed on the south side of the trail that will drain to the south culvert area. The south culvert will also undergo repairs. The culvert located in the north repair area will be filled and abandoned in place. 4 Item 6: The estimated time required to compete operation. Tree clearing will occur prior to the work required to complete the repairs. In total, construction time is expected to be no greater than ten months. Item 7: Hours and months of operation. Work will occur within regular hours, starting no earlier than 7:00 a.m. and finishing no later than 6:00 p.m. on a daily basis. Work is anticipated to occur between the months of February and December of 2020. Item 8: A tree survey indicating the location and type of all trees over six inches in caliper. In a heavily wooded area only the boundaries of the tree areas must be indicated on the survey. A tree survey was conducted to identify trees over 6 inches in diameter at breast height (dbh). The area within the construction limits is heavily wooded. Collecting individual tree locations was not feasible given that the area is heavily wooded. Instead, a square measuring 2,500 square feet was surveyed in three different locations along the south repair area. On average, about 7 trees at or above 6 inches dbh were identified within the surveyed squares. Tree clearing will take place in areas as necessary within the limits of construction (Attachment 3) and will be avoided to the extent practicable. Trees over 6 inches dbh that are removed during construction will be counted and replanted at a 1:1 ratio within the construction limits during restoration as space allows. Some areas where trees will be removed will not be replanted due to new features being constructed. Refer to sheet R-03 (Attachment 3) for the tree replacement plan. Item 9: An end use landscape plan and interim screening plan for the operation period. The restoration plan is provided in Attachment 3, sheets R-01 through R-04. An interim screening plan is not applicable to this project. Item 10: The plan of operation, including processing, nature of the processing and equipment, location of the plant source of water, disposal of water and reuse of water. Not applicable. Item 11: Travel routes to and from the site and the number and type of trucks that will be used. Access to the north repair area will be from Highview Drive along the trail. An access road will be constructed from Highview Drive for truck and equipment access. An application for a right-of-way permit will be submitted to the City of Eden Prairie once the contractor has been selected and construction dates are finalized. The City of Eden Prairie permit is required to obtained authorization for constructing a temporary access route in the City of Eden Prairie right-of-way. The timeline for submitting the application in late winter/spring of 2020 and the application requirements have been discussed with the City of Eden Prairie. Access to the south repair area will be from Flying Cloud Drive via Moon Valley Aggregate property (pending owner approval). Equipment used will include a backhoe or similar excavator, small bulldozers, light bobcat(s), and trucks to transport personnel, equipment and material. 5 Beyond the direct access routes into the project area, it is anticipated that most construction related traffic would use County Highway 1 and County Highway 61. Item 12: Plans for drainage, erosion and sediment control and dust control. No drainage will occur as part of this project. Erosion and sediment control best management practices (BMPs) are outlined in the storm water pollution prevention plan (SWPPP) included in Attachment 3, sheets C-05 and C-06. Item 13: A restoration plan providing for the orderly and continuing restoration of all disturbed land to a condition equal to or better than that which existed prior to the earth work. Such plan shall illustrate, using photographs, maps and surveys where appropriate, the following: a. The contour of the land prior to excavation and proposed contours after completion of excavation and after completion of restoration. Refer to Figure 2 for current topographic contours and refer to Attachment 3, sheet G-08 for topographic contours after project completion (regraded area along trail modifications). b. Those areas of the site to be used for storage of topsoil and overburden. The site does not currently contain much topsoil. It is anticipated that the contractor will strip what topsoil they can and stockpile it in the staging areas, but most of the topsoil used in site restoration will likely need to be imported. c. A schedule setting forth the timetable for excavation of land lying within the extraction facility. Refer to items 6 and 7 for a schedule of the proposed activities. d. The grade of all slopes after restoration, based upon proposed land uses, and description of the type and quantity of plantings where revegetation is to be conducted. Refer to Attachment 3, sheets G-08 for area that will be regraded and sheets R-01 through R-03 for the restoration plans. The construction area will be re-seeded using MnDOT approved seed mixes. Types of seed mixes are outlined on the restoration plan (sheet R-01, Attachment 3) with a total area to be seeded of up to 7.41 acres. e. The criteria and standards to be used to achieve final restoration as well as intermittent stabilization. Intermittent stabilization will be achieved with the use of erosion and sediment control BMPs. Final restoration will be achieved per the restoration plan (sheet R-01 through R-03, Attachment 3). For further information refer to the SWPPP on sheets C-05 and C-06 (Attachment 3). 6 Item 14: A statement identifying the applicant's program to insure compliance with the permit conditions, method of response to complaints and resolving conflicts that may arise as a result of complaints. HCRRA will obtain coverage under the Minnesota Pollution Control Agency’s General Permit for Construction Stormwater. As such, required inspections under that coverage will be completed and will serve as means to oversee compliance with the permit conditions. Conflicts that are brought to the City’s attention can be directed to Jessica Galatz (612) 348-2691. Item 15: Unless exempt under Minnesota Rules, an environmental assessment worksheet, if required by the city. Not applicable. Item 16: A wetland alteration permit, if required by the City Code, which shall be processed concurrently with the excavation permit application. A joint application form for activities affecting water resources in Minnesota was submitted to the U.S. Army Corps of Engineers and serves to fulfill the city’s wetland alteration requirement. It is provided as Attachment 5 for reference. The application materials are supported by field delineations completed in 2015 and 2019. Delineation work was confirmed by the City of Chanhassen’s technical evaluation panel, as noted in the attached application materials.

Tolerances 1. Pipe installed by the directional drilled method must be located in plan as shown on the Drawings, must be no shallower than shown on the Drawings, and must be no closer than minimum offsets shown on the Drawings, unless otherwise approved. Plot the actual horizontal and vertical alignment of the pilot bore at intervals not exceeding 30 feet. This "as built" plan and profile shall be updated as the pilot bore is advanced. At all times, provide and maintain instrumentation that will accurately locate the pilot hole and measure drilling fluid flow and pressure. Grant Engineer access to all data and readout pertaining to the position of the bore head and the fluid pressures and flows. 2. Employ experienced personnel to operate the directional drilling equipment and, in particular, the position monitoring and steering equipment. No information pertaining to the position or inclination of the pilot bores shall be withheld from Engineer. 3. Each exit point shall be indicated with an over-length tolerance of 5 feet for directional drills of 1,000 linear feet or less and 20 feet for directional drills of greater than 1,000 linear feet and an alignment tolerance of 5 feet left/right with due consideration of the position of the other exit points and the required permanent easement. The alignment of each pilot bore must be approved by Engineer before pipe can be pulled. If the pilot bore fails to conform to the above tolerances, Engineer may exercise option to require a new pilot boring to be made. 4. After the pipe is in place, cleaning pigs shall be used to remove residual water and debris. After the cleaning operation, provide and run a sizing pig to check for anomalies in the form of buckles, dents, excessive out-of-roundness, and any other deformations. The sizing pig run shall be considered acceptable if the survey results indicate that there are no sharp anomalies (e.g. dens, buckles, gouges, and internal obstructions) greater than 2 percent of the nominal pipe diameter, or excessive ovality greater than 5 percent of the nominal pipe diameter. For gauging purposes, dent locations are those defined above which occur within a span of five feet or less. Pipe ovality shall be measured as the percent difference between the maximum and minimum pipe diameters. For gauging purposes, ovality locations are those defined above which exceed a span of five feet. I. Ream and Pullback 1. Reaming: Reaming operations shall be conducted to enlarge the pilot after acceptance of the pilot bore. The number and size of such reaming operations shall be conducted at the discretion of Contractor. 2. Pulling Loads: The maximum allowable pull exerted on the HDPE pipelines shall be measured continuously and limited to the maximum allowed by the pipe manufacturer so that the pipe or joints are not over stressed. 3. Torsion and Stresses: A swivel shall be used to connect the pipeline to the drill pipe to prevent torsional stresses from occurring in the pipe. 4. The lead end of the pipe shall be closed during the pullback operation. 5. At all times, handle the HDPE pipe in a manner that does not over stress the pipe. Vertical and horizontal curves shall be limited so that wall stresses do not exceed 50% of yield stress for flexural bending of the HDPE pipe. If the pipe is buckled or otherwise damaged, the damaged section shall be removed and replaced by Contractor at Contractor’s expense. Take appropriate steps during pullback to ensure that the HDPE pipe will be installed without damage. 6. Tracer wire shall be pulled along with the HDPE pipe in order to locate it in the future. Conductivity between HDPE sections shall be continuous. J. Handling Drilling Fluids and Cuttings 1. During the drilling, reaming, or pullback operations, the Contractor shall make adequate provisions for handling the drilling fluids, or cuttings at the entry and exit pits. To the greatest extent practical, these fluids must not be discharged into a waterway. When Contractor's provisions for storage of the fluids or cuttings on site are exceeded, these materials shall be hauled away to a suitable legal disposal site. After completion of the directional drilling work, the entry and exit pit locations shall be restored to original conditions. Comply with all permit provisions. 2. Pits constructed at the entry or exit point area shall be so constructed to completely contain the drill fluid and prevent its escape. Excess drilling fluid shall be contained in a lined pit, a containment pond, or via another Engineer approved containment method at exit and entry points until recycled or removed from the site. 3. Utilize drilling tools and procedures which minimize the discharge of any drill fluids. Comply with all mitigation measures listed in the required permits and elsewhere in these Specifications. 4. To the extent practical, maintain a closed loop drilling fluid system. 5. Minimize drilling fluid disposal quantities by utilizing a drilling fluid cleaning system which allows the returned fluids to be reused. 6. Make all diligent efforts to minimize the amount of drilling fluids and cuttings spilled during the drilling operation and provide complete clean-up of all drilling fluid overflows or spills. 3.07 ENVIRONMENTAL PROVISIONS A. The Horizontal Directional Drilling operation shall be operated in a manner to eliminate the discharge of water, drilling mud and cuttings to adjacent waters or land areas during construction. Provide equipment and procedures to maximize the recirculation or reuse of drilling mud to minimize waste. All excavated pits used in the drilling operation shall be lined by Contractor with heavy duty plastic sheeting with sealed joints to prevent the migration of drilling fluids and/or ground water. B. Visit the site and become aware of all structures and site limitations at the directional drill locations. Contractor is responsible for providing a drilling plan outlining procedures to prevent drilling fluid from adversely affecting the surrounding area. C. The general work areas at the entry and exit shall be enclosed by a berm to contain unplanned spills or discharge. D. Waste cuttings and drilling mud shall be processed through a solids control plan, comprised as a minimum of sumps, pumps, tanks, centrifuges, material handlers, and haulers all in a quantity sufficient to perform the cleaning/separating operation without interference with the drilling program. The cuttings and excess drilling fluids shall be disposed offsite and shall be dewatered and dried by Contractor to the extent necessary for offsite disposal. Water from the dewatering process shall be treated by Contractor to meet permit requirements and disposed of locally. The cuttings and water for disposal are subject to being sampled and tested. The construction site and adjacent areas will be checked frequently for signs of unplanned leaks or seeps. E. Equipment (graders, shovels, etc.) and materials (such as groundsheets, hay bales, booms, and absorbent pads) for cleanup and contingencies shall be provided in sufficient quantities by Contractor and maintained at all sites for use in the event of inadvertent leaks, seeps or spills. F. Waste drilling mud and cuttings shall be dewatered, dried, and stock piled such that it can be loaded by a front end loader, transferred to a truck and hauled offsite to a suitable legal disposal site. The maximum allowed water content of these solids is 50% of weight. G. Treatment of water shall satisfy regulatory agencies before it is discharged. 3.08 POST-INSTALLATION TELEVISING A. Televise pipeline after completion of installation. The pipe shall be cleaned prior to any televising. The Contractor shall be responsible for cleaning the pipe, and keeping it free of debris until final project acceptance by Engineer.

Attachment 5 Joint Application Form for Activities Affecting Water Resources in Minnesota Minnesota Interagency Water Resource Application Form February 2014 Page 1 of 15 Joint Application Form for Activities Affecting Water Resources in Minnesota This joint application form is the accepted means for initiating review of proposals that may affect a water resource (wetland, tributary, lake, etc.) in the State of Minnesota under state and federal regulatory programs. Applicants for Minnesota Department of Natural Resources (DNR) Public Waters permits MUST use the MPARS online permitting system for submitting applications to the DNR. Applicants can use the information entered into MPARS to substitute for completing parts of this joint application form (see the paragraph on MPARS at the end of the joint application form instructions for additional information). This form is only applicable to the water resource aspects of proposed projects under state and federal regulatory programs; other local applications and approvals may be required. Depending on the nature of the project and the location and type of water resources impacted, multiple authorizations may be required as different regulatory programs have different types of jurisdiction over different types of resources. Regulatory Review Structure Federal The St. Paul District of the U.S. Army Corps of Engineers (Corps) is the federal agency that regulates discharges of dredged or fill material into waters of the United States (wetlands, tributaries, lakes, etc.) under Section 404 of the Clean Water Act (CWA) and regulates work in navigable waters under Section 10 of the Rivers and Harbors Act. Applications are assigned to Corps project managers who are responsible for implementing the Corps regulatory program within a particular geographic area. State There are three state regulatory programs that regulate activities affecting water resources. The Wetland Conservation Act (WCA) regulates most activities affecting wetlands. It is administered by local government units (LGUs) which can be counties, townships, cities, watershed districts, watershed management organizations or state agencies (on state-owned land). The Minnesota DNR Division of Ecological and Water Resources issues permits for work in specially-designated public waters via the Public Waters Work Permit Program (DNR Public Waters Permits). The Minnesota Pollution Control Agency (MPCA) under Section 401 of the Clean Water Act certifies that discharges of dredged or fill material authorized by a federal permit or license comply with state water quality standards. One or more of these regulatory programs may be applicable to any one project. Required Information Prior to submitting an application, applicants are strongly encouraged to seek input from the Corps Project Manager and LGU staff to identify regulatory issues and required application materials for their proposed project. Project proponents can request a pre- application consultation with the Corps and LGU to discuss their proposed project by providing the information required in Sections 1 through 5 of this joint application form to facilitate a meaningful discussion about their project. Many LGUs provide a venue (such as regularly scheduled technical evaluation panel meetings) for potential applicants to discuss their projects with multiple agencies prior to submitting an application. Contact information is provided below. The following bullets outline the information generally required for several common types of determinations/authorizations. • For delineation approvals and/or jurisdictional determinations, submit Parts 1, 2 and 5, and Attachment A. • For activities involving CWA/WCA exemptions, WCA no-loss determinations, and activities not requiring mitigation, submit Parts 1 through 5, and Attachment B. • For activities requiring compensatory mitigation/replacement plan, submit Parts 1 thru 5, and Attachments C and D. • For local road authority activities that qualify for the state’s local road wetland replacement program, submit Parts 1 through 5, and Attachments C, D (if applicable), and E to both the Corps and the LGU.

This wetland delineation report was approved on December 18, 2015 (Appendix A). A second wetland delineation was completed on September 2019, for the expanded project area. This wetland delineation has been reviewed by the technical evaluation panel and the approval letter is attached. Minnesota Interagency Water Resource Application Form February 2014 Page 4 of 15 Describe the project that is being proposed, the project purpose and need, and schedule for implementation and completion. The project description must fully describe the nature and scope of the proposed activity including a description of all project elements that effect aquatic resources (wetland, lake, tributary, etc.) and must also include plans and cross section or profile drawings showing the location, character, and dimensions of all proposed activities and aquatic resource impacts. Project Description: The scope of the project includes landslide repairs on a portion of the Minnesota Bluffs LRT Regional Trail (trail) in Chanhassen, MN owned by the Hennepin County Regional Railroad Authority (HCRRA). Two areas will be repaired as part of this project – the north repair area and the south repair area. Project access will be from Highview Drive in Eden Prairie, proceeding southwest along the trail to the site, and also from Flying Cloud Drive through the Moon Valley Aggregate operated property (final access route through Moon Valley Aggregate operated property pending property owner authorization). Landslide repairs in the south repair area will include stabilizing the south slope, repairing the south culvert outlet area and constructing a new storm sewer and drainage ditch to direct water into the repaired area. Existing trail profile grades will be reduced with the embankment slopes regraded to less steep grades and finished with turf reinforcement mats. The existing damaged concrete headwall will be removed and existing riprap will be salvaged for reuse. The south culvert outlet area will be repaired with riprap, boulder cross vanes, and a stilling basin. Work in the north area will include removal of existing pipe debris, placement of riprap fill on north slope, and abandonment of the existing pipe crossing beneath the trail. Drainage will be rerouted from north pipe area via new buried storm sewer and lined drainage channel, which will discharge to the south culvert outlet area.Please refer to Appendix B for the complete set of design plans and layout of the aforementioned project featrues. Project Purpose and need In 2014, a large rain event (presidential declared disaster 41823) caused the slopes supporting the trail to fail. The trail has since been closed due to slope instability and public safety concerns. The purpose of the proposed project is to stabilize the trail slopes, reopen the trail, and thereby reconnect a six-year closure of a Tier 1 Alignment of the Regional Bicycle Transportation Network. Aquatic Resources Two wetland delineations were conducted within the project area. The first delineation was completed in August 2015. The Second wetland delineation was completed in September 2019 to accommodate the proposed construction limits in their entirety. The wetland delineations identified two wetland areas (0.49 acres) and one unnamed stream channel within the project area (Figure 2). The two wetland areas (Wetland 1, wetland 2) are incidental wetlands located within the ditch of the trail. Both wetlands contained of three communities; shallow marsh, shrub-carr, and wet meadow. The shallow marsh segment of the wetland is located on the northern end of the proposed access route. As the wetland extends southwest, the slopes gradually increase causing the plant community to change from a shallow marsh to shrub- carr and wet meadow. Using the Cowardin classification method the wetland areas were classified as palustrine emergent wetlands that are partially seasonally flooded and temporarily flooded and ditched (PEMAd/PEMCd). The unnamed stream was originally delineated as part of the 2015 wetland delineation report. The stream channel was classified as a type 1 (RUBA) seasonally flooded sparsely vegetated stream channel. Work conducted in Aquatic Resources The proposed repairs will require work to be conducted within the two delineated wetlands and unnamed stream. A constructed 10-foot wide access road is required along the existing trail to provide access for construction materials and equipment. Portions of the trail corridor are too narrow and require placement of temporary fill in the existing ditches (wetlands 1 and 2) to create the required 10-foot wide access route. Approximately 0.06 acres of temporary fill will be placed within wetlands 1 and 2 (Appendix B, Pg G-05). Once construction is completed, the fill will be removed and the ditches will be returned to as close to the pre-project existing conditions as possible. Minnesota Interagency Water Resource Application Form February 2014 Page 5 of 15 The proposed repair work requires 0.025 acres (86 cubic yards) of riprap be placed within approximately 79 linear feet of the existing stream channel. This portion of stream has been previously impacted due to installing riprap for an emergency repair in 2016. An additonal, 0.092 acres (64 cubic yards) of riprap will be placed below the ordinary high water level downstream from the emergency repair area. The placement of this riprap will impact approximately 294 linear feet of stream channel and help further protect the stream banks and prevent further bank erosion and sedimentation downstream (Appendix B, pg C-13). Schedule Tree clearing would be completed in the spring of 2020. Construction is anticipated to begin in the summer/fall of 2020 and commence by the end of 2020. Special considerations Threatened and Endangered Species A threatened and endangered species assessment was completed for the proposed project. The review identified two federally listed species and five state listed species occurring within one-mile of the project area (Appendix C). Rare natural Communities No records of rare natural communities are shown in the NHIS database within the project area. Special Fish and Wildlife Resources The project is expected to improve fish and wildlife habitat along the unnamed stream channel. The stream is an intermittent stream and does not support fish populations. Stabilization of the adjacent slope and stream bank will help improve downstream water quality by reducing the amount of sediment loading into the stream channel. The project will not block or impede potential fish passage. Cultural Resources In 2015, a review of records at the Minnesota State Historic Preservation Office (MSHPO) was requested to identify any previously recorded archaeological, historical, or architectural resources within the project area. Per the Minnesota Archaeological Inventory and Historic Structures Inventory for the project area, no archaeological sites were identified and one historic feature was identified within Section 25, T116N, R23W (Appendix D). This property will not be affected by the proposed project. In November 2019, a second record search was submitted to MSHPO for the expanded project area. No additional cultural resources were identified. Groundwater sensitivity The project will not directly impact groundwater since excavations will occur up to 10 feet below the ground surface. Sensitive Surface Waters The MDNR Pubilc Waters Inventory (PWI) did not identify any basins or watercourses within the Project area. No sensitive surface waters such as impaired waterbodies or trout waters were identified within the project area. Tree Removal It is anticipated the proposed project will require tree removal around the north and south repair area. Large trees will be avoided to the degree practical. Tree clearing will be conducted between November 1 and March 31 to limit impacts to sensitive wildlife species. All trees removed with >6” dbh will be replaced in accordance with the City of Chanhassen’s permit requirements (Appendix B, R-02).

Tributary impacts must be reported in linear feet of impact and an area of impact by indicating first the linear feet of impact along the flowline of the stream followed by the area impact in parentheses). For example, a project that impacts 50 feet of a stream that is 6 feet wide would be reported as 50 ft (300 square feet). 3This is generally only applicable if you are applying for a de minimis exemption under MN Rules 8420.0420 Subp. 8, otherwise enter “N/A”. 4Use Wetland Plants and Plant Community Types of Minnesota and Wisconsin 3rd Ed. as modified in MN Rules 8420.0405 Subp. 2. 5Refer to Major Watershed and Bank Service Area maps in MN Rules 8420.0522 Subp. 7. If any of the above identified impacts have already occurred, identify which impacts they are and the circumstances associated with each: 1 The term “impact” as used in this joint application form is a generic term used for disclosure purposes to identify activities that may require approval from one or more regulatory agencies. For purposes of this form it is not meant to indicate whether or not those activities may require mitigation/replacement. Minnesota Interagency Water Resource Application Form February 2014 Page 9 of 15 Project Name and/or Number: Attachment A Request for Delineation Review, Wetland Type Determination, or Jurisdictional Determination By submission of the enclosed wetland delineation report, I am requesting that the U.S. Army Corps of Engineers, St. Paul District (Corps) and/or the Wetland Conservation Act Local Government Unit (LGU) provide me with the following (check all that apply): Wetland Type Confirmation Delineation Concurrence. Concurrence with a delineation is a written notification from the Corps and a decision from the LGU concurring, not concurring, or commenting on the boundaries of the aquatic resources delineated on the property. Delineation concurrences are generally valid for five years unless site conditions change. Under this request alone, the Corps will not address the jurisdictional status of the aquatic resources on the property, only the boundaries of the resources within the review area (including wetlands, tributaries, lakes, etc.). Preliminary Jurisdictional Determination. A preliminary jurisdictional determination (PJD) is a non-binding written indication from the Corps that waters, including wetlands, identified on a parcel may be waters of the United States. For purposes of computation of impacts and compensatory mitigation requirements, a permit decision made on the basis of a PJD will treat all waters and wetlands in the review area as if they are jurisdictional waters of the U.S. PJDs are advisory in nature and may not be appealed. Approved Jurisdictional Determination. An approved jurisdictional determination (AJD) is an official Corps determination that jurisdictional waters of the United States are either present or absent on the property. AJDs can generally be relied upon by the affected party for five years. An AJD may be appealed through the Corps administrative appeal process. In order for the Corps and LGU to process your request, the wetland delineation must be prepared in accordance with the 1987 Corps of Engineers Wetland Delineation Manual, any approved Regional Supplements to the 1987 Manual, and the Guidelines for Submitting Wetland Delineations in Minnesota (2013). http://www.mvp.usace.army.mil/Missions/Regulatory/DelineationJDGuidance.aspx Minnesota Interagency Water Resource Application Form February 2014 Page 10 of 15 Project Name and/or Number: Attachment B Supporting Information for Applications Involving Exemptions, No Loss Determinations, and Activities Not Requiring Mitigation Complete this part if you maintain that the identified aquatic resource impacts in Part Four do not require wetland replacement/compensatory mitigation OR if you are seeking verification that the proposed water resource impacts are either exempt from replacement or are not under CWA/WCA jurisdiction. Identify the specific exemption or no-loss provision for which you believe your project or site qualifies: WCA: 8420.0105 Subp. 2. D. USACE: Nationwide Permit 13: Bank stabilization and Nationwide Permit 3: Maintenance Provide a detailed explanation of how your project or site qualifies for the above. Be specific and provide and refer to attachments and exhibits that support your contention. Applicants should refer to rules (e.g. WCA rules), guidance documents (e.g. BWSR guidance, Corps guidance letters/public notices), and permit conditions (e.g. Corps General Permit conditions) to determine the necessary information to support the application. Applicants are strongly encouraged to contact the WCA LGU and Corps Project Manager prior to submitting an application if they are unsure of what type of information to provide: WCA Under 8420.0105 Subp. 2. D WCA does not regulate impacts to incidental wetlands. The two delineated wetlands that would be temporarily impacted by the proposed project are manmade ditched wetlands. These ditches are meant to convey water away from the trail. However, due to the lack of slope, water has ponded in the trail area creating a narrow wetland within an upland area. The project will place approximately 0.06 acres of fill within the incidental wetland area. This fill will be temporary and removed upon completion of the project. The ditches will then be restored to as close to the pre-project existing conditions as possible. USACE: It is anticipated that work within Waters of the U.S. can be completed under Nationwide Permit 3 and/or Nationwide Permit 13. Maintenance Activities: The proposed project would need to repair 0.025 acres (86 cubic yards) of riprap within approximately 79 linear feet of the existing stream channel. Some riprap was originally placed in this segment of the stream channel as part of a previous emergency repair needed to stabilize the south culvert outlet. Since then the riprap has been displaced during subsequent flood and runoff events. The proposed project would salvage existing riprap and also install additional riprap to further protect the area from future erosion. Bank Stabilization Activities: Bank stabilization activities necessary for erosion control or prevention, such as vegetative stabilization, bioengineering, spills, riprap, revetment, gabion baskets, stream barbs, and bulkheads, or combination of bank stabilization techniques. In order to stabilize the bank of the unnamed stream, 0.092 acres (64 cubic yards) of riprap will be placed below the ordinary high water level. The placement of riprap will impact approximately 294 linear feet of stream channel.

Concurrence with a delineation is a written notification from the Corps and a decision from the LGU concurring, not concurring, or commenting on the boundaries of the aquatic resources delineated on the property. Delineation concurrences are generally valid for five years unless site conditions change. Under this request alone, the Corps will not address the jurisdictional status of the aquatic resources on the property, only the boundaries of the resources within the review area (including wetlands, tributaries, lakes, etc.). Preliminary Jurisdictional Determination. A preliminary jurisdictional determination (PJD) is a non‐binding written indication from the Corps that waters, including wetlands, identified on a parcel may be waters of the United States. For purposes of computation of impacts and compensatory mitigation requirements, a permit decision made on the basis of a PJD will treat all waters and wetlands in the review area as if they are jurisdictional waters of the U.S. PJDs are advisory in nature and may not be appealed. Approved Jurisdictional Determination. An approved jurisdictional determination (AJD) is an official Corps determination that jurisdictional waters of the United States are either present or absent on the property. AJDs can generally be relied upon by the affected party for five years. An AJD may be appealed through the Corps administrative appeal process. In order for the Corps and LGU to process your request, the wetland delineation must be prepared in accordance with the 1987 Corps of Engineers Wetland Delineation Manual, any approved Regional Supplements to the 1987 Manual, and the Guidelines for Submitting Wetland Delineations in Minnesota (2013). http://www.mvp.usace.army.mil/Missions/Regulatory/DelineationJDGuidance.aspx BWSR NOD Form – November 5, 2019 1 Minnesota Wetland Conservation Act Notice of Decision Local Government Unit: City of Chanhassen County: Carver Applicant Name: Jessica Galatz, Hennepin County Regional Rail Authority Applicant Representative: Sarah Johnson, Barr Engineering Project Name: HCRRA Minnesota River Bluffs LRT Regional Trail Slope Stabilization Delineation Update LGU Project No. (if any): Date Complete Application Received by LGU: 10/30/2019 Date of LGU Decision: 12/5/2019 Date this Notice was Sent: 12/9/2019 WCA Decision Type - check all that apply ☒Wetland Boundary/Type ☐Sequencing ☐Replacement Plan ☐Bank Plan (not credit purchase) ☐No-Loss (8420.0415) ☐Exemption (8420.0420) Part: ☐ A ☐ B ☐ C ☐ D ☐ E ☐ F ☐ G ☐ H Subpart: ☐ 2 ☐ 3 ☐ 4 ☐ 5 ☐ 6 ☐ 7 ☐ 8 ☐ 9 Replacement Plan Impacts (replacement plan decisions only) Total WCA Wetland Impact Area: Wetland Replacement Type: ☐ Project Specific Credits: ☐ Bank Credits: Bank Account Number(s): Technical Evaluation Panel Findings and Recommendations (attach if any) ☐ Approve ☐ Approve w/Conditions ☐ Deny ☒ No TEP Recommendation LGU Decision ☐ Approved with Conditions (specify below)1 ☒ Approved1 ☐ Denied List Conditions: Decision-Maker for this Application: ☒ Staff ☐ Governing Board/Council ☐ Other: Decision is valid for: ☒ 5 years (default) ☐ Other (specify): 1 Wetland Replacement Plan approval is not valid until BWSR confirms the withdrawal of any required wetland bank credits.

(Barr) has completed a threatened and endangered species desktop review for the Hennepin County Regional Railroad Authority (HCRRRA) Slope Failure Project. The project area consists of 9.58 acres centered on the Minnesota River Bluffs LRT Regional Trail. Located within the City of Chanhassen and City of Eden Prairie Minnesota, Section 23, T116W, R23N. Federally listed species are protected by the federal government under the Endangered Species Act and require consideration for projects involving federal permits. State listed species are protected under Minnesota’s Endangered and Threatened Species Law and must be considered for state level permitting requirements. The project area was reviewed for federal and state listed species and their associated habitats that may be found in the project area. This desktop review was completed in November 2019 using a combination of data available from the United States Fish and Wildlife Service (USFWS) and the Minnesota Department of Natural Resources (MNDNR). 1.1 Federally listed species The USFWS Information, Planning, and Conservation System (IPaC) identified two federally listed species as occurring within the project area, the northern long-eared bat (Myotis septentrionalis; federally threatened) and the Rusty patched bumble bee (Bombus affinis; federally endangered). No designated critical habitat for any federally listed species is located within the project area. The northern long-eared bat inhabits caves, mines, and forests. According to the MNDNR, the nearest hibernacula is over 6.7 miles southwest of the project area, and no maternity roost trees have been identified within the vicinity of the project area. To minimize the potential impact on the species tree clearing will be conducted between November 1 and March 31. Therefore, project clearing activites completed prior to April 1, 2020 are anticipated to have no effect on northern long-eared bat. Rusty patched bumble bees are typically found in grasslands with flowering plants from April through October. They are typically nesting in underground and abandoned rodent cavities or clumps of grasses above ground as nesting sites. During the winter months, queens typically overwinter in underground cavities in upland forests dominated by maple-basswood or oak-hickory trees. The project area is located within USFWS designated High Potentail Zone for the rusty patched bumble bee. The USFWS Section 7 guidance recommends USFWS consultation for projects located within the High Potential zone.

(Barr) has a license agreement (LA-898) with the MNDNR for access to the Natural Heritage Information System (NHIS) database, which was queried in November 2019 to determine if any rare species could potentially be affected by the proposed Project. Two state-listed species have been previously recorded within the project area; American ginseng (Panax quinquefolius), and smooth rock cress (Boechera laevigata). In addition, the NHIS database identified five, state-endangered, threatened, special concern or watchlist species have been documented within one mile of the proposed project area (Table 1). Five native plant communities were also noted. Table 1 Rare Species Documented within One Mile of Proposed Project Area According to MNDNR NHIS Common Name Scientific Name Federal Status State Status Habitat1 Kitten-tails Besseya bullii N/A Threatened Primarily found in oak savanna communities, though it occurs in dry prairies and oak woodlands. Plants show a preference for partial to open light and upper slopes. Some populations exhibit a preference for less xeric north facing slopes in prairie habitats. Soils are most often sandy to gravelly, well-drained soil derived from alluvium or limestone. Smooth Rock Cress Boechera laevigata N/A Special concern Found to occur on slopes in mesic deciduous forests. Lark Sparrow Chondestes grammacus N/A Special concern Typically in dry short prairie grasslands in areas with sand or gravel spoils with some bare ground and scattered trees. American Ginseng Panax quinquefolius None Special concern Typically found in well-developed forest soil, mesic loamy soil. Gophersnake Pituophis catenifer None Special concern Prefers well-drained, loose sandy and gravel soils. 1: Habitat information obtained from MDNR Rare Species Guide: https://www.dnr.state.mn.us/rsg/index.html Kitten tails is the only state listed threatened species identified within one mile of the project area. Primary habitat for the species consists of oak savanna communities on north facing slopes. No such habitat is present within the project area. The majority of the project area is densely wooded deciduous forest with a southeast facing slope. No dry prairie is present. Therefore it is unlikely for the species to be located within the project area. The remaining state listed species are listed as species of special concern. These species are monitored by the DNR but are not protected under state law. APPENDIX D SHPO Historical/Architectural Resource CR-CHC-049 Memorandum Technical Memorandum To: Jessica Galatz From: Joel Swenson Subject: SHPO Historical/Architectural Resource CR-CHC-049 Date: 09/15/2015 Project: 23101014.00/004-100 c: Kristin Alstadt As part of finalizing Task 2 and moving into final design, Task 3, the HCRRA (Hennepin County Regional Rail Authority) and the Barr design team needed to understand the existence and extents of any wetlands or fens within HCRRA right-of-way. This would include anything that would impact the design option selected by HCRRA. A preliminary desktop review of the site was performed by Barr staff in February, 2015. A complete wetland delineation was recently performed June 17, 2015. A report summarizing the preliminary and final wetland delineation findings was submitted to the HCRRA in July. In addition to the wetland delineation, the Minnesota State Historical Preservation Office was contacted by Barr staff to perform a database search for potential historical and archaeological resources within this area of Section 25 and 36, of Township 116, Range 23 in the City of Chanhassen within Carver County. According to the SHPO database, a historic feature (CR-CHC-049) is placed south of the landslide as shown on Figure 1 (also attached). Figure 1. Historical/Architectural resource database results To: Jessica Galatz From: Joel Swenson Subject: SHPO Historical/Architectural Resource CR-CHC-049 Date: 09/15/2015 Page: 2 P:\Mpls\23 MN\10\23101014 Landslides in Chanhassen HCRRA\WorkFiles\Wetland Evaluation\SHPO\Technical Memorandum_SHPO.docx The Historic feature is listed as a house (highlighted in yellow in Figure 2). Figure 2. Historical/Architectural Inventory To further investigate the potential for cultural resources within the project area or vicinity, Barr staff scheduled a visit to the SHPO office to pull the file for this Inventory Number CR-CHC-049. Upon arriving at the office, it was determined that a file had not been created for this inventory number as of the afternoon of July 10, 2015. Julie Hillenbrand (a grant process facilitator at SHPO) left a voicemail with Barr staff KNA the next morning on July 11, 2015 stating that their independent contractor who they hire to create the files has not provided them with any documentation for this inventory number. Julie and Tom Cinadr (property information/database searches at SHPO) both indicated that they had no idea when they expected to receive files for this inventory number.
