EXECUTIVE SUMMARY The Mill Street Trail Improvements, City Project No. 13 -07, was initiated based on the City's Trail Implementation Program. Improvements along Mill Street proposed for construction in 2014 include approximately 2,400 feet (0.45 miles) of bituminous trail to be constructed on the east side of Mill Street between the southern Shorewood City limits with Chanhassen at Lilac Lane and the northern Shorewood City Limits with Excelsior. Trail improvements along Mill Street are proposed for the following reasons: • Provide an off - street access route for pedestrians from the east side of the roadway at the Shorewood City limits with Chanhassen to the Shorewood City limits with Excelsior. • Improve pedestrian and vehicle safety. • Control area drainage and improve existing drainage problems, if feasible. • Improve water quality of storm water runoff in the area. A map illustrating the project location can be found on Figure I in Appendix A. A total estimated project cost for the proposed trail and storm sewer improvements is approximately $699,000, which includes 10% construction contingency and indirect costs in the amount of 24% of the estimated construction costs. The indirect costs include legal, engineering, administrative, and financing items. Easement acquisition will be necessary to construct the trail as proposed herein but due to the variability in land acquisition issues has not been included in the total estimated project cost. Funding for the project will be provided through 100% City funds. No assessments, grants or other funding methods have been proposed with this project at this time. To supplement City funds, the City may wish to apply for various grants identified in Section 3. It is proposed that construction begin in May 2014 and be completed by the end of August 2014, including all restoration items. This project is feasible, necessary, and cost - effective from an engineering standpoint, and should be constructed as proposed herein. The economic feasibility of this project will need to be determined by the City Council.

MILL STREET TRAIL IMPROVEMENTS PROJECT 2.1 Introduction 2.1.1 Authorization On July 8, 2013, the Shorewood City Council authorized the preparation of an Engineering Feasibility Report for the Mill Street Trail Improvements project. This project has been designated as City Project No. 13 -07. 2.1.2 Scope /Project History The Shorewood Trail Implementation Plan was adopted by City Council in October of 2011 and amended in March of 2013 to identify the existing and proposed pedestrian improvements throughout the developed areas of the City. The plan was created to link existing pedestrian facilities to provide a safe and comprehensive network to serve the community. The Shorewood Trail Implementation Plan, shown in Appendix B, identifies a future trail extension along Mill Street between the Chanhassen /Shorewood City limits to the south and the Excelsior /Shorewood City limits to the north and lies within the Minnehaha Creek Watershed District (MCWD). The proposed project is located along the east side of Mill Street. The improvements within this report have been proposed to address trail extensions in accordance with the City's Trail Implementation Plan, MCWD requirements, and Minnesota Department of Transportation (MnDOT) standards and include the following: • Improve pedestrian and vehicle safety • Provide an off - street access route for bicycles and pedestrians • Construct project to Hennepin County standards • Control area drainage and improve existing drainage problems, if feasible. • Improve water quality of storm water runoff in the area • Minimize construction impacts to adjacent properties The project area is identified on Figure I in Appendix A of this report. Feasibility Report Mill Street Trail Improvements City of Shorewood Project No. 13 -07 WSB Project No. 1459 -82 Page 2 2.1.3 Data Available Information and materials used in the preparation of this report include the following: • City of Shorewood Record Plans • Field Observations of the Area • Field Review • Private Utility Maps • Discussions with City and County staff • Topographic survey of the project area • City of Shorewood Trail Implementation Plan, dated October 2011 and amended March 2013 2.2 Existing Conditions 2.2.1 Existing Road Conditions Mill Street general consists of a 40- foot -wide, rural roadway section with no curb and gutter and appears to have followed the original rolling topography with some cutting and filling to achieve the present grade. The road surface includes two 12 -foot lanes with an 8 -foot shoulder on the east and west sides of the roadway. The project area contains mostly residential properties and contains landscaping, overhead utilities, mature trees, and numerous other private improvements beyond the edge of bituminous pavement. The width of the existing right -of -way is generally 66 feet. 2.2.2 Existing Drainage Mill Street is currently graded as a rural- section road with ditches and culverts conveying runoff directly to the existing wetlands. The rolling topography of Mill Street splits drainage at the high points located midblock between Lilac Lane and Brand Circle and midblock between Brand Circle and Hillendale Road. The storm water flows north and south to the low points located at Lilac Lane, Brand Circle, and Apple Road where the runoff discharges to the east to the adjacent respective wetlands. 2.2.3 Wetlands Three wetlands are present near the proposed proj ect location. The wetlands are within close proximity to where construction is proposed, but should not be affected directly by the proposed project. Feasibility Report Mill Street Trail Improvements City of Shorewood Project No. 13 -07 WSB Project No. 1459 -82 Page 3 2.3 Proposed Improvements 2.3.1 Proposed Trail Mill Street is a Hennepin County Arterial roadway with a few intersectiong local side streets to residential neighborhoods. Trail improvements along the east side of Mill Street will provide an off - street route for pedestrians between the Shorewood City limits with Chanhassen to the south and the Shorewood City limits with Excelsior to the north. The east side of the roadway is the ideal location for the trail improvements as an 8 -foot bituminous trail currently exists on the east side of Mill Street south of Rose Lane in Chanhassen and a narrow sidewalk, approximately 4 — foot - width, along the east side of the roadway north of 3rd Avenue in Excelsior. There will remain a gap in the trail system between cities and direct connections to the existing Chanhassen and Excelsior trail system will require extensions north and south of the Shorewood City limits by Excelsior, Chanhassen, and /or Hennepin County. These two sections have been considered in the design review, but have not been included in cost estimates or further planning in relation to this report. Discussions regarding these potential gap connections have been discussed with Chanhassen, Excelsior, and County Staff informally. Proposed trail improvements along Mill Street include installing new concrete curb and gutter along the east side of Mill Street to provide separation from the trail and to convey drainage of the roadway, reducing the existing roadway width from 40 -feet (edge of bituminous -to -edge of bituminous) to 36 -feet (edge of bituminous -to -face of curb). The proposed roadway will generally consist of a 12 -foot lane with an 8 -foot shoulder on the west side (as exists today) and an 11 to 12 -foot lane with 4 -foot shoulder on the east side. The proposed trail would be constructed with a variable 1 to 5 -foot wide boulevard and a 2 -foot wide grass buffer from the outside edge of the trail to the right -of -way line where possible. The design will consider the preservation of neighborhood features such as trees, landscaping, driveways, and wetlands. A number of utility poles are currently located along the east side of Mill Street. Impacts to existing utilities may be mitigated by relocation to the boulevard areas. In areas of limited right -of -way or natural features, retaining walls are proposed to minimize impacts and reduce the number of easements required. The trail is proposed to be installed where off -road pedestrian facilities do not currently exist which will impact adjacent properties. Typical impacts associated with the construction of a new trail include tree removal, fence removal /replacement, grading within front lawn areas, irrigation relocation, removal and replacement of driveway approaches, relocation of existing private utilities, storm water facilities, and modifications to existing driveway grades. Work associated with these items will primarily occur within the public right -of -way, but driveway removal and grading within the yard may extend further into adjacent properties. Detailed impacts to properties are typically determined during the final design process. The proposed pavement section for the trails will consist of 3 inches of bituminous pavement and 6 inches of class 5 aggregate base (100% Crushed Limestone), over an Feasibility Report Mill Street Trail Improvements City of Shorewood Project No. 13 -07 WSB Project No. 1459 -82 Page 4 acceptable, compacted subgrade. The existing subgrade material is generally suitable for use; however there will likely be areas where unsuitable subgrade materials will be encountered during construction. Unsuitable materials will need to be excavated and replaced with suitable granular material. A geotextile fabric will be placed to separate the existing underlying materials from the granular materials as required in these corrected subgrade areas. A typical section can be found in Figure 2 of Appendix A. 2.3.2 Accessibility /Americans with Disabilities Act (ADA) Considerations The proposed trail will meet ADA design standards and will be constructed in accordance with the MnDOT standard plans found in Appendix C. 2.3.3 Storm Sewer Improvements The proposed trail and curb construction will eliminate the ditch on the east side of Mill Street. The addition of storm sewer inlets and pipes are necessary to convey runoff from the roadway to the existing wetlands and low lands. The proposed storm sewer system is designed to convey the 10 -year peak flow rates as required by State -Aid standards and the policies identified in the City's Surface Water Management Plan. The proposed storm sewer improvements maintain the existing drainage patterns and discharge points to the greatest extent possible. In areas where the proposed trail is not adjacent to the curb, drain tile will be installed within the boulevard. The new curb and gutter will improve conveyance of runoff along Mill Street, but will require inlets to collect runoff and meet spacing requirements. The State -Aid standard that will control the design is the catch basin spacing and location in conjunction with the existing wetlands and low lands. Wherever possible, connection to existing culverts will be utilized to maintain discharge points. Prior to storm water discharge, sump manholes are proposed to collect sediment to improve water quality. 2.3.4 Storm Water Quality Improvements Storm water quality improvements are not required by the Minnehaha Creek Watershed District (MCWD) as part of this project. 2.3.5 Wetlands Wetland impacts are not anticipated as part of this project. 2.4 Easements and right -of -way 2.4.1 Existing and Proposed Right -of -Way The majority of existing right -of -way for Mill Street is 66 feet wide. The properties from which right -of -way or permanent easement must be obtained before construction of the trail can occur are listed below. Feasibility Report Mill Street Trail Improvements City of Shorewood Project No. 13 -07 WSB Project No. 1459 -82 Page 5 * Temporary easements required during construction will be evaluated during final design. 2.4.2 Drainage and Utility Easements In addition to the above - listed properties, there are a number of properties that will require drainage and utility easements and temporary construction easements due to the loss of storm water storage, storm water conveyance in the east ditch, and slope impacts within the right -of -way. Easements required for storm sewer improvements will be evaluated during final design. 2.5 Street Sign/Private Utility Relocation Existing signs and private utility poles within the limits of the proposed trail are proposed to be relocated to accommodate the new trail. Signs and private utility poles will be relocated to provide a 2 foot clearance zone from the roadway and the trail within the boulevard areas. Easements required for private utility relocation will be evaluated during final design. 2.6 Permits An NPDES permit for construction activity will be required since more than one (1) acre will be disturbed by construction activities with the project. A permit from the Minnehaha Creek Watershed District (MCWD) will be required for erosion control and storm water management for the proposed trail and storm sewer improvement. 2.7 Construction Access /Staging The contractor will be responsible for providing access to all properties throughout the project. Adequately signed traffic control will be identified to direct traffic around the construction zones and notify users of the increased truck and construction activity.

CONCLUSIONS AND RECOMMENDATIONS The Mill Street Trail Improvements project includes trail and storm sewer improvements along the east side of Mill Street between the Shorewood City limits with Chanhassen and the Shorewood City limits with Excelsior. Based on the preceding discussions, the following conclusions have been made: The trail widths and alignments proposed for reconstruction have been set in an effort to minimize disturbance to adjacent properties and to improve pedestrian and vehicle safety of the area. Construction of the trail as proposed presents a minimally disruptive approach to trees, natural resources, and existing surface water facilities in the area to the greatest extent possible. 2. Extensive use of retaining walls will be required to minimize disturbance to adjacent properties and wetlands. Reduced lane widths and /or traffic restrictions on Mill Street will be necessary during construction to accommodate storm sewer installations. 4. The trail improvements as proposed herein can accommodate both bicyclists and pedestrians Most of the underlying soils in the area are generally suitable for construction. Soil corrections will be necessary in some locations of the project. Both options proposed have similar pavement sections. 6. The Contractor will be responsible for protecting the existing bituminous surface on the road from damage by saw cutting the edge and adding the curb and gutter. 7. This project does not propose to assess benefitting properties and therefore will not require a formal public hearing process for the Council to order the project, but it is in the City's best interest to hold public meeting(s) to present and discuss the project. The total estimated cost for the Mill Street Trail Improvements project, including trail and storm sewer improvements, is $699,000. Proposed funding for the project is provided through 100% City funds. This project is feasible, necessary, and cost - effective from an engineering standpoint. The project feasibility is subject to financial review by the City. Based on the information contained in this report, it is recommended to proceed with the improvements as outlined in this report.
