E E&OWG Meeting Notes 10/1/13 at 7pm in the Community Room In Attendance: Bob Gubrud, John Howard, Bill Sierks, Andy Harmon, Chuck Prentice, Stacy of CEE and Paul Thompson. 1. Greetings and brief sharing of current happenings. 2. Minutes from 9/3/13 meeting approved unanimously. 3. Residential Energy Usage: CEE Presentation by Stacy. Stacy began by giving some background information on the Home Energy Squad (HES) program: • HES has won awards, well regarded nationally. • No income ceiling for efficiency loans. • CEE works with the MAC for airplane noise abatement. • One homeowner needs to be home during the visit/install. • Periodically hold workshops to do education, attend events to find HES participants. Following the explanation of the program, Stacy provided statistics on home energy use: • Residential use accounts for 23% of energy use - area targeted by HES visit. • For typical home, energy is divided: 10% water heating, 15 % appliances, 20% for lighting, 55% for HVAC. • Triangle sign on water heater is recommended setting, corresponds to about 120 degrees F. Also reduces the likelihood of scalding. • Efficient toilets are 1.5 gallons/flush. Efficient bathroom fixtures can save $35/year. • Front loading washers can use 40 gallons less per wash. • Xcel will buy old fridge for $35. • Recommend power strip to reduce phantom load, could be $14/year savings. • Powering down computer hard drive saves more than turning down/off the monitor. • A CFL saves $5 per year, but needs to be recycled. • LED is an additional charge, costs around $10-15/bulb. • Programmable thermostat could save $91- biggest saver. • All told, $330 savings/year if all options are implemented. • HES puts together a report showing the energy saving potential of different options. 4. EWG & E&OWG collaboration Community solar has hit a snag, seemingly with Xcel. Paul is hosting events at his home about the community solar system on Oct. 11th and Nov. 15th. Community solar is apparently big in Colorado. 10 5. Edina Day of Service: Oct. 26 a. HES installs- Four HES will be available for Edina day of service. Bob is working with Chris at the Edina Resource Center. b. Publicity- may be less than last year although there was an article in Edina magazine recently publicizing the day. It is still possible to make event plans, so John will attempt to plan a buckthorn pull. Paul would like to see an Edina solar tour, could do video of events in the future. 6. Enhanced HES Status: Sign-ups & Installs- 23 are done, 2 are scheduled, so 5 remaining. Publicity Plans; a. About Town Article published in the fall edition. 7. EEC workplan a. April Event ideas - Earth day is around Easter, which may cause the event to be after Earth day (Tues., April 22). Tentative plan is April 17th - Thursday, or the week after at Edina High School. Having local flavor may draw in community, and Paul would like to see local emphasis. Celebrity could add draw, ideas include: Paul Douglas, Jon Foley, Maggie Koerth-Baker, Jon Seeley, or Jon Abraham. Semi famous people that could be a draw include a university president or Mr. Mooty of Dairy Queen. 8. Community Events a. Monthly video discussion groups- Number of films cover possible topics; ones that come to mind are Thin Ice Climate, Planeat, Carbon Nation, and Chasing Ice. Likely there is a licensing fee, often around $100 for public screening. Impression is the commission would be able to cover this cost. b. Partners- Chuck shared his experience periodically hosting environmental movies at libraries over the last 5 years. Chuck would be happy to work with us. Chuck will look into Chasing Ice for our first film. Tentative dates for showings are Nov. 12, Dec. 10th, Jan. 14th, and mid February. Chuck will look into locations and pricing. 9. Next meeting: Flog, 29=3 Rescheduled to Nov. 13. Adjourned at 9:35pm. Andy Harmon and Chuck Prentice are interested in officially joining the working group. Approved at October EEC meeting. 11 Notes from EBR meeting held on Wednesday, October 16th 2013 at Edina City Hall.

Predicted Utility Savings Actual Utility Savings 726 Therms 1,322 Therms Predicted $$ Actual $$ $629 $1,130 180 CCF 487 CCF $1,731 $2,114 Excess Savings $884 The following graphs depict the actual pre and post -flow measurements on specific fixture types. Please see Appendix E for Additional Supporting Information. CITY CF EDINA I YEAR I M&V REPORT 8 QTV 25 4. Conclusions & Recommendations McKinstry recommends utilizing all systems as commissioned to maintain savings obligations. Further savings can be achieved by ensuring the light fixtures in unoccupied spaces are kept off, water usage is kept to minimal necessary levels, and space temperatures and schedules are adjusted for the typical occupancy patterns throughout the year. The following chart depicts the utility rates used to determine dollar savings from the calculated energy savings. The rates are taken directly from the Performance Contract signed between McKinstry and the City of Edina. City Hall $0.07 $0.77 $4. Braemar Arena $0.09 $0.63 $4. Art Center $0.10 $0.82 $4.

Edina, Minnesota 55424 www.EdinaMN.gov • 952-927-8861 • Fax 952-826-0390 33 September 20, 2013 The Honorable James B. Hovland 4801 W 50th Street Edina, MN 55424 Dear Mayor Hovland, As chair of the newly launched national Resilient Communities for America campaign (ResilientAmerica.org), I'm writing to invite you to join me and an elite group of mayors and other local elected officials for an opportunity to demonstrate your leadership in response to America's extreme weather, climate, energy, and economic challenges. Resilient Communities for America is a critical and innovative initiative led by mayors and other local elected officials who are building resilience through infrastructure renewal, clean energy, and preparedness initiatives while strengthening our local economies and improving the health of our communities. Central to the campaign is the Resilient Communities for America. Agreement, a sign -on letter in which local leaders make a commitment to action on resilience. We launched the initiative just a few short months ago and already have more than 80 cities and other local governments on board including the mayors of Cincinnati, OH; Kansas City, MO; New Orleans, LA; Denver, CO; and county supervisors from Arlington County, VA and Broward County, FL. Resilient Communities for America gives shape to an emerging movement and provides a platform for local officials to speak with one voice on the need for better -prepared communities, the leadership of local governments, and the need for collaboration with state and federal agencies and with the private sector. The broad-based campaign is led by four outstanding non-profit organizations ICLEI USA, United States Green Building Council, the National League of Cities and World Wildlife Fund. These organizations and other partners are providing valuable tools and resources to signatory communities, including opportunities for signatories to connect with the White House, FEMA and other federal agencies on particular local needs, and free capacity -building tools for local government staff. Over the past two years extreme weather events have threatened our cities and our nation like never before — they have taken hundreds of lives and cost us an estimated $188 billion in 2012 alone. Meanwhile many of our cities have aging and vulnerable infrastructure, reliance on unsustainable energy supplies and a deep need for creating good paying sustainable jobs that cannot be outsourced. I know you agree that we cannot ignore these interrelated threats to the vitality of our cities. In fact, we must redouble our efforts to create more resilient I C L E I NATIONAL 016 Local LEAGUE ` Governments ,USA o for Sustainability of CITIES Q" WWF 34 communities that are able to bounce back from disruptions and sustain a good quality of life for all. While the White House, federal agencies, and Congressional leaders have all recognized the importance of building resilience, we know that the work and leadership must come from the local level. You and other leaders around the country are taking proven actions to prepare for extreme weather events and the repercussions from a changing climate; to rebuild outdated community infrastructure; and to attract investment and create jobs by building safer and more sustainable places. That's resilience in action. The solutions are here today, and we must not let the opportunities slip away or go unnoticed. I hope you will join me as a signatory of the Resilient Communities for America Agreement. We will be announcing our latest signatories this fall at the National League of Cities meeting in Seattle and I hope we can include you in the announcement. To participate, simply sign the attached Agreement letter, scan and email it to Patrice.parsons@iclei.org, or sign online at www. resitientamerica. org/sign-the-e-agreement-here/ More information can be found on the campaign website, and ICLEI USA's Outreach Director Patrice "Pete" Parsons would be happy to speak with you or an appropriate staff member to answer any questions you may have. Pete can be reached directly at 210-722- 7270. Thank you very much for your leadership and for your consideration of this opportunity.

Utility improvements and repairs amount to ,$X,XXX,000 and will be funded through their respective utility fund. The project'can be completed during the 2014 construction season. Staff 'believes the project is necessary, cost effective and feasible to improve toe infrastructure as initiated by the vision of Edina's Vision 20/20 — "Livable Environment" and "A Sound Public Infrastructure". LOCATION: The project includes 541h Street between the Wooddale Avenue right -of - 'way (ROW) to the west and the France Avenue ROW to the east for a total distance of approximately 2,640 feet (Figure 1). Page 1 of 23 40 INITIATION & ISSUES: The project was initiated by the Engineering Department as part of the City's Municipal State Aid. Street reconstruction program and identified in the Capital Improvement Program. As part of this project the City collaborated with the Minnehaha Creek Watershed District (MCWD) to address`cr6ek issues and needs and develop a separate comprehensive water resource management plan for the Arden Park Area. This feasibility study addresses updating 'aging infrastructure issues associated with the pavement condition, a structurally deficient bridge, and stormwater collection and conveyance within the project corridor. All Engineering projects are reviewed for compatibility with the City of Edina 2008 Comprehensive Plan Update, Comprehensive Bicycle Transportation Plan, the Comprehensive Water Resource Management Plate, the Living Streets Policy and Envision'"' Sustainability Evaluation. City of Edina 2008 Comprehensive Plan Update Sidewalk Facilities Chapter 7 of the plan addresses locations of proposed sidewalks facilities within the City. As shown in Figure 7.10 of Appendix F, a sidewalk is proposed along 54'" Street between Wooddale Avenue and France Avenue. Bicycle Facilities Chapter 7 of the plan addresses locations of proposed bicycle facilities within the City as part of the Comprehensive Bicycle Transportation Plan. Page 2 of 23 41 Figure 7.11 of Appendix F identifies 54th Street as a secondary bicycle route between Wooddale Avenue and France Avenue. City of Edina Comprehensive Water Resource Management Plan The project is located within the Minnehaha Creek Watershed District. The Comprehensive Water Resource Management Plan indicates no storm water issues within the street right of way. Living Streets Policy and EnvisionT"" Sustilhabilliltv Evaluation The vision statement of the Living Streetsolicy, attached in Appendix K, expresses the need to look at projects; differently in the future: Living Streets balance the needs pf motorists,'pedestrians, bicyclists, and transit riders in ways that promote safety `'and , convenience, enhance community identity, create'economic vitality; •., improve environmental sustainability, and provide meaningful opportunities for, active living and better health. Although the Living Streets Plan ,-has not been developed, staff has included elements that pertain to collector streets such as 54th Street in the rehabilitation of the infrastructure and replacement of the road. For the very first time, , taff used : -a sustainability scoring system for this project calledENVISIONTM .to help measure what effect project decisions and recommendations have ;,:on sustainability. ENVISIONTM was developed in joint,, collaboration between the Zofnass Program for Sustainable Infrastructure. at the Harvard Graduate School of Design and the Institute for Sustainable Infrastructure'. ENVISIONlh was created to support transformational, collaborative approaches that.promote sustainable infrastructure development using a .comprehensive, triple bottom line approach toward decision-making. It is intended to foster a, 'necessary and dramatic improvement in the performance and resiliency of physical infrastructure across the full economic, social, and environmental dimensions of sustainability. The rating 's, ystem includes a total of 60 credits organized into five 'categories: '- i Quality of Life: Goal is to improve the project's impact on the surrounding community • Leadership: Goal is to strengthen collaboration, stakeholder involvement, and long-term planning considerations • Resource Allocation: Goal is to wisely manage materials, energy, and water resources used for project • Natural World: Goal is to understand and minimize negative environmental impacts of project ' The Institute for Sustainable Infrastructure is a not for profit education and research organization founded by the American Public Works Association, the American Society of Civil Engineers, and the American Council of Engineering Companies Page 3 of 23 42 Climate and Risk: Goal is to minimize emissions and design for resilience - in both the short-term and long-term Within each credit, points are earned based on revel of achievement obtained from "improved" to *enhanced" to "superior" to "conserving" to "restorative." The project was evaluated based on a set of 52 ENVISIONT"A credits that were determined to be most relevant to this project and the Arden Park Stormwater Management Plan. The ENVISION''" evaluation was conducted at three stages during the planning process. During the first "stage, the project team identified ENVISIONTM credits deemed most relevant to the critical issues identified through stakeholder engagement including intercept surveys and door knocking. During the second stage the project team used ENVISIONT14 to evaluate the alternative desigh scenarios for each of the three .project sections (West End, Middle Section, and East End). Results of this evaluation were presented at the September 30;' final scenario workshop and are summarized in Appendix L. Finally, ENVISIONTm was used by the project team to evaluate the preferred design alternative that is being presented as part of this study. Overall project., scoring is shown in Figure 2 and detailed results of this evaluation are summarized In Appendix L. Overall Scaring 200 ----- 180 - - - 160 140 120 100 80 so "I NATURAL WORLD KI RESOURCE ALLOCATION P LEADERSHIP 40 20 — + QUALITY OF LIFE 0 Total Points Figure 2 -Overall Project Scoring Using Envision-rm Page 4 of 23 43 Overall, the preferred alternative scored 176 points out of a possible ;500 points. The scores will increase substantially as the project moves from the feasibility phase to the detailed design and construction phases. At this stage of the project there was no basis to assign points to a large number of the credits available because decisions related to those credits have not yet been made. The preferred design scored highest in terms of Quality of Life (85 points), Leadership (44 points), and Climate and Risk (27 points). It achieved fewer points for Natural World (11 points) 4hd Resource Allocation (9 points). In terms of Quality of Life, the preferred design scored well because it improves quality of life for the,�heighborhood, encourages alternative modes of transportation, im proves `` site accessibility, safety, and way finding, and enhances public spaces. For Leadership, the pSoject scored well because of the City and project team's effective leadership and commitment to the project, a robust stakeholder involvement process, a id.efforts to improve infrastructure integration (such as Iinking,the,Arden Park and 54th Street reconstruction project planning). In the Climate and Risk category, the project scored moderately well, - reflecting the fact that the design (in,particular raising the bridge) helps the community prepare for long-term adaptability and short-term hazards associated with,changing climate conditions. Minimizing pavement use also helps manage beet island effects. For the Natural World criteria, the project scored very low because at this stage of the project it isnot possible to score several of the credits. The project team and City are addressing a number of these credits, especially those related.`to"the creek, and as the project moves forward there will be an opportunity to capture points associated with factors such as: .protecting surface water, preserving floodplain functions, and preventing surface water contamination. In;terms of Resource Allocation, the project scored very low because at `this stage: there is no formal commitment or design that will support sustainable procurement, use regional materials, divert waste from landfills, reduce excavated materials taken off site, or other related factors. Addressing this category of credits in the next phase of the project will significantly increase scoring. Staff Issues The following existing issues and/or features, some generated by stakeholders, are addressed in this study: • Pedestrian, bicycle and vehicle safety • Minnehaha Creek access/safety • Recreational use at Minnehaha Creek as it relates to 54th Street • Parking capacity • Poor condition of existing pavement surface Page 5 of 23 44 • Storm water quality and drainage • Existing landscaping, retaining walls and driveways • Existing mature trees Summary Stakeholder Engagement Process and Outcomes This robust, collaborative, and transparent engagement served as a pilot/model for the City. Below is a summary of both the process and outcomes. Technical and Engagement Parameters (June 13, 2013): The City and consulting team jointly determined the key engagement issues and "promise" to the public, agreed on core'engagement values, identified and analyzed the project's key stakeholders, and determined the project's technical and engagement parameters. The resulting Stakeholder Engagement Plan drove all engagement activities and communications. The technical parameters framed the project within the context of City policies, plans, and regulations including sidewalks, bike facilities, and special assessments; Watershed policies and plans, and the partnership with the City to help address Minnehaha Creek's iMpalred waterway status; and MnDOT State,Aid requirements for this roadway. Input on Needs and Issues (late June -late July 2013): Over 450 stakeholders offered issues and needs for both projects through doorknockirig, Intercept surveys, online surveys, and small group sessions in response to questions around issues and needs on 54th Street and thb bridge, and stormwater-related issues and needs for Minnehaha Creek ..and Arden Park. All input was documented and reported back to .the"conimunity, and informed the preliminary street design components and stormwater management plan. Broad categories of input- were aesthetics; Creek access and safety; water quality and runoff; parking availability; road geometry and pavement conditions; safety for pedestrians; bicyclists, vehicles, Creek users: lighting and signage; and traffic and speeding. See detailed report in Appendix A. Feedback on Design Components (August 2013): Based on that input, the consulting team developed a variety of design components and received great feedback from over 112 stakeholders attending a workshop or completing an online survey. Participants provided either positive or negative feedback on each design component. See detailed report in Appendix B. Roadway Configurations (sidewalks, bike lanes, arki Many participants still weren't aware of the MnDOT/City 0 roadway requirements. Feedback on specific design components varied considerably and was often highly individualized. Stakeholders with Page 6 of 23 45 Feasibility Study 54'" Street Roadway Reconstruction Improvement No. BA -416 October 21, 2013 children, walkers and bikers, and Arden Park and Creek users more often provided positive feedback on the practical and safety advantages of these requirements. There was generally positive feedback on one vs. two sidewalks, and varied feedback on where parking was needed and why, and the value of boulevards; there were many more concerns about the narrower western section of the roadway. Some drivers and bicyclists were frustrated about the "mixed messages" about bike lanes/sharrows on the east end of the road. Some stakeholders wanted more parking for Park and Creek, as well as church attendees. Others were concerned about the impact on people's property -even though the City owns that right-of-way. Pedestrian and Bicyclist Safety, Speeding: Original stakeholder issues and needs prioritized pedestrian and bicyOist safety, so numerous design components focused on those topics. Feedback continued to support safety as a key priority. Many concerns and opinions reflected the interconnections among effectiveness, cost, and appropriateness of various speed reduction and pedestrian crossing safety design components. There were concerns about flas4ing signals and stakeholders took various positions on pedestrian crossing aesthetics, but there was clear consensus on the need for safe crossings. Bridge Safety and Creek Access: Feedback on the bridge designs varied, and many participants preferred a bridge that maintains the area's "country" feel ;and fits with the residential area. Others focused on designs that allow Creek users sufficient headroom; many were attracted to the possibility of a path underneath the bridge. Stakeholders posed important questions about. Creek access and use as well, including positive feedback on ar) updated canoe landing that is not "slickery" when wet, and how landings or steps can double as places to play, watch, and otherwise have fur' a60 be safe alongside the Creek. Water., Quality,oadi Park : o in While there appeared to be general understand ng . � and support for the need for stormwater management, a number of the design components in this category garnered a range of positive and negative feedback. There was a lot of feedback on filtration design components, with generally positive feelings about including native plants. Stakeholders generally favored maintaining green space and existing park uses, and ensuring that any new design ' cgmponents address water safety especially in 4 play areas. Feedback on Design Scenarios (September 2013): The design team developed alternative scenarios for different segments: west, middle/bridge plus Creek and Page 7 of 23 M Feasibility Study 54th Street Roadway Reconstruction Improvement No. BA -416 October 21, 2013 stormwater, and east. Each of these brought together feedback on the design components with MnDOT and City plans and policies. At the session and subsequent online survey, c. 120 stakeholders offered feedback. See detailed report in Appendix C. Middle/bridge. Creek. stormwater: There was very strong support for Scenario 1 that directly addressed stakeholder -identified safety issues at that intersection for both crossings and vehicle/bicycle stopping, and also maintained the rapids for recreational use. For canoe landing, bridge, and railing designs, etc., there was solid preference for a more natural look, but these component design choices;. merit more specific input and feedback once the process moves for*grd. West end: The scenarios for this narrower section of roadway generated the most response, especially fr�olm residents on 54th Street. The concerns were overwhelmingly focused, on' ways to avoid or minimize property impacts from any of the options. Widespread objections to dedicated bike lanes in Scenario 1 focused, on the property impacts of the additional 10' of pavement; the sharrow option garnered more support. (See West+East below.) East end: These scenarios generated; varied responses, again with many concerns about property ° impacts with an additional sidewalk plus dedicated bike lanes and 'parking in various configurations. The option to mix bike, ,lanes and sharrows caused some to worry this would confuse drivers and bicyclists. Feedback 'generally supported one-sided parking, with mixed feedback and ;questions about the need for extra or special parking on the north side (See West+East below.) •, -West+East: Most stakeholders supported a sidewalk on one side, but the varied' opinions about.north versus south side suggest that the volume of infomnatign may,have resulted in misunderstandings about impacts. Some recommended,'centering the roadway to "share the pain" on both north -and south sides, ' Many questioned the purpose and width of even the smaller 2' curbs. Everyone preferred preserving trees. Most supported more and better lightirig, and many specified the design must be downward-facing/sky-friendly.

Street The street was originally constructed in 1954. The existing street is surfaced with bituminous pavement. Patches, longitudinal cracking and transverse Page 8 of 23 47 Feasibility Study 54th Street Roadway Reconstruction Improvement No. BA -416 October 21, 2013 cracking are present throughout the street section as shown in Figures 3 and 4. The existing pavement is generally in poor condition. Figure 3- Looking West from OaklaWn Avenue towards Kellogg Avenue Figure 4- Looking East from Halifax Avenue to France Avenue As part of this study, a total of four (4) soil borings were taken along 54�' Street. The borings identified an 8 to 17 -inch thick layer of poorly graded gravel base material beneath the pavement. Plastic sandy loam soils beneath the street section are poor and do not provide proper structural capacity for the existing street section. Page 9 of 23 48 Feasibility Study 54th Street Roadway Reconstruction Improvement No. BA -416 October 21, 2013 The average pavement condition index (PCI) for the City of Edina is 51 and the average PCI for 54`h Street as calculated in 2009 is approximately 20. The City of Edina recently hired a consultant to evaluate all bituminous roadways within the City. The streets were graded based on a number of conditions such as sagging, alligator cracking, raveling and potholes. Streets are rated on a scale from 0 to 100; with 0 being extremely poor and 100 representing a brand new road surface. The City evaluates the PCI values of streets to determine a proper maintenance program. Streets with a PCI less than 45 are evaluated for total reconstruction, PCI's between 45 and 65 are evaluated for mill and overlays,, and PCI's greater than 65 are considered for seal coats. The pavement surface of the street "appears ;to be near the end of its useful life while the costs to maintain and repair the road are steadily increasing. Overlaying or seal coating the pavement is no longer feasible. Street grades vary throughout the area from approximately 0.4 percent to 7.5 percent*. Currently, 54th Street has two (2) distinct and different street typical sections west and east of the bridge at Minnehaha Creek. West Segment Typical Section The existing street between Wooddale.Avenue and the bridge at Minnehaha Creek is abutted by residential, properties. The street varies in width from 29 - feet to 34 -feet with ' no parking,. concrete, curb and gutter or sidewalks on either side. This segment includes 57foot dedicated bicycle lanes on both sides. A three space bump -out vehicle parking area exists west of the bridge at Minnehaha Creek \'. .The existing street between' the bridge at Minnehaha Creek and France `Avenue is abutted ''by residential, commercial and civic properties. The street has an, existing width of 40 -feet with concrete curb and gutter and ;8 -foot parking lanes on both sides. The street is striped with 5 -foot advisory bike lanes m , both directions inside of the dedicated parking lanes. The concrete curb, and gutter. and pavement are generally in poor condition. Metro. Transit operates a total of seven (7) bus stops on each side of 541h Street between and including Wooddale Avenue and France Avenue. The existing bus stops are typically located at each intersecting street. Existing stop signs are in-place at the Minnehaha Boulevard intersection. >''there are nineteen (19) residential and five (5) commercial driveway entrances along the street. Two (2) residential driveway pavements feature decorative concrete textures and brick paver blocks along the west segment of 54th Street. Figure 5 depicts a driveway with brick paver block edging found in the project area. Page 10 of 23 49 Feasibility Study 50 Street Roadway Reconstruction Improvement No. BA -416 October 21, 2013 Figure 5 — 5357 Oaklawn Avenue - Paver Block Driveway and Retaining Walls Sidewalks and Bicycle Facilities Existing sidewalk is present along the south side of 54`h Street beginning east of the Edna Lutheran Community Church parking lot up to 4015 54" Street for approximately 250 -feet and along the north and south side of 54th Street beginning at 3907 54, Street up to the France Avenue ROW for approximately 135 -feet on each side. The existing sidewalk is in satisfactory condition.,.54 Street Is identified as a secondary bicycle route and contains dedicated.,and advisory,lanes on the west and east segments respectively. ,ightino Street lighting in the project area consists of standard cobra head lights mounted on wood pales that are typically located at intersections of side streets. The locations of the existing street lights are shown in Appendix H. Traffic, Parkino and Crash Data Average daily traffic volumes ranged from 1,166 to 2,602 cars per day with 85`h percentile speed ranging from 29.8 to 30.5 mph. Traffic and crash data are included In Appendix G. A parking study was conducted on the east side of the project area from Minnehaha Boulevard to France Avenue to determine existing parking capacity and usage rates. Parking study results are shown In Appendix J. Landscapina Fourteen (14) private retaining walls and decorative landscaping features are located in the ROW in the project area. Many of these landscape items are located directly behind the edge of the street. Figure 6 shows a typical landscaping feature found in the project's ROW. Page 11 of 23 Feasibility Study 54"' Street Roadway Reconstruction Improvement No. BA -416 October 21, 2013 Figure 6 — 5336 Brookview Avenue - Landscaping Feature The existing geometry of the intersections at Park Place and Minnehaha Boulevard creates large surface areas of pavement and intersection corners with long radius curb -lines. This existing geometry allows vehicles to comfortably maneuver through the intersection at speeds higher than typical or desirable for conVentfonal intersections. This situation can lead to diminished pedestrian crossing safety and requires additional city resources during snow removal ope tions. The existing geometric configuration of the intersections'is shown in Figure 7. 5333 EXISTING EDGE OF PAVEMENT %Y �B C,10 *� •� .. 54TH ST EXISTING CURB AND GUTTER ! 4200 4113 Figure 7 — Existing Geometric Configuration at the Park Place and Minnehaha Boulevard Intersections Page 12 of 23 51 Feasibility Study 54'h Street Roadway Reconstruction Improvement No. BA -416 October 21, 2013 Recreational Creek Use and Brida The project area contains unique recreational opportunities at Minnehaha Creek due to its configuration near the existing bridge and the presence of a grade control structure. During moderate to high flow conditions, the existing grade control structure causes the creek water to form rapids that are enjoyed by experienced users. A photo of the existing rapids is shown in Figure 8. Typically, recreational users access Minnehaha Creek by parking on Minnehaha Boulevard or on 54u' Street. Currently, there is an unmarked creek landing area located on the eastern creek bank north of the bridge. Based on observations and stakeholder feedback, lesser experienced users avoid the rapids by crossing 541h Street near the bridge. Stakeholders overwhelmingly identified these crossings as common and unsafe since no clearly marked pedestrian crossing(s) exist(s). The Minnehaha Creek Watershed District recognizes the unique recreational opportunities in this area, but has also identified the grade control structure as a source of inhibiting water quality and aquatic growth upstream of the project area. The existing bridge at Minnehaha Creek was originally constructed in 1935 and widened to the current configuration in 1948. The structure is a single span comprised of steel beams with a ' concrete deck that has been paved over with bituminous as part of previous street surfacing projects. The main span is 32 -feet long and the deck is 33,5 -feet wide including concrete curb and gutter and a 4 -foot sidewalk on the south side. The superstructure is supported on high concrete abutments and wingwalls. The bridge is not eligible for 'the Natkn' al Register of Historic Places. MnDOT's Structure Inventory Report shown in Appendix i; identifies the bridge as Structurally Deficient with a Sufficiency* Rating of 40.2. The existing bridge railing is rated substandard. The bridge is also load restricted and posted. A photo of the existing bridge is shown n Figure 8. :ek Page 13 of 23 52 Feasibility Study 54th Street Roadway Reconstruction Improvement No. BA -416 October 21, 2013 Public Utilities Water Main The existinq� water main system layout is shown in Appendix D. Properties abutting 54t Street east of Halifax Avenue are served from a 8 -inch cast iron trunk water main pipe that was constructed in 1946. The valves are operable and the trunk pipe is in satisfactory condition due to no record of pipe breaks. In 2009, the City repaired two (2) water service pipe breaks at 4109 and 4113 54th Street. All other properties abutting 54th Street are 'served by trunk water main pipes located in north/south intersecting streets. Trunk water main pipe was never installed along 54th Street between Halifax Avenue and Park Place to loop the City's water system. System pressure and water quality needs are satisfactory without this missing trunk pipe, but are,not optimal. Sanitary Sewer The existing sanitary seW6r<system layout is shown in Appendix D. Properties abutting 54th Street east of Halifax Avenue are served from � a 9 -inch clay trunk sanitary sewer pipe that was constructed in 1952. Historical records indicate there have been no sewer; backups or blockages in the trunk or service pipes. All .,other propertiesy abutting 54th Street are served by trunk sanitary sewer pipes located in north/south intersecting streets. Storm Sewer The ,existing storm,_ sewer system layout is shown in Appendix D. The storm sewer system is located within the legal boundary of Minnehaha Creek Watershed. ;Resident feedback identified ice problems near the bridge during Winter. No locations 'of 'either localized surface drainage issues or street a flooding during heavy storm, events were identified by stakeholders. Private Utilitles v Providers of privately "owned gas, electric, communications and cable television utilities are present in the neighborhood. These utilities are either -overhead or buried underground both within and outside the street ROW. The'.decision-making framework used to arrive at the recommended improvements presented in this report is driven by the pilot Stakeholder Engagement Process and Envision Sustainable Infrastructure Rating System summarized previously and detailed in the Appendix. Proposed ':improvements address many of the issues and concerns raised by stakeholders while still balancing and maintaining required minimum State and City engineering standards. The project includes adding to 54th Street shared vehicle and bicycle lanes, a sidewalk on the north side of 54th Street with lighting and a new bridge and railing at Minnehaha Creek. The project involves removing and replacing all existing concrete curb and gutter and reconstructing the bituminous pavement and a portion of the poor subgrade soils. The project also involves installation of storm sewer that meets State Aid standards and connecting Page 14 of 23 53 Feasibility Study 54th Street Roadway Reconstruction Improvement No. BA -418 October 21, 2013 sump pump drain pipe to the storm sewer system as needed. The project will also involve trunk water main pipe installation in order to connect existing water pipe systems on either side of Minnehaha Creek. Street The project will reconstruct the street with a bituminous surface to approximately its existing widths on the west and east segments respectively, The project will recycle and mix the existing bituminous street pavement and the amounts of aggregate base below it together to form a material that can be used as utility trench backfdl or as a suitable material to replace poor subgrade soils on other City street reconstruction projects. The project will remove and replace all of the sections of existing concrete curb and gutter. New concrete driveway aprons are proposed whether they are present today or not. The stop signs at the Minnehaha Boulevard intersection are proposed to remain in place. 54"' Street West Segment Typical Section The proposed street typical section between Wooddale Avenue and the bridge at Minnehaha Creek is shown in Figure 9. The bump -out vehicle parking area west of the bridge at Minnehaha Creek will be reincorporated into the project.

Staff will also inquire about ridership along 54`" Street and determine if bus stops can be consolidated along the corridor. Small concrete bus stop pads may be placed at proposed bus stops where no sidewalk exists. As shown in Figure 12, the project will reduce the curb radii at the intersections of Park Place and Minnehaha Boulevard. These reductions will reduce turning vehicu'ar speeds, make vehicle turns more deliberate for drivers and predictable for pedestrians, and decrease the amount of future maintenance performed by the City at these intersections. 1 AND E�UTtfl nut=RNK 1 1 -- ------ --- <.. µ MZ '00 34TH ST MN GRIN NMl— — ^'.

A number had questions about the purpose and need for the above -water portion of the grade control structure. As of the date Of this draft feasibility study, the MCWD was exploring the feasibility of removing the structure while maintaining a form of rapids for recreational use. Based on feedback receivea, stakeholders generally prefer creek landings similar to the one shown in Figure 13. This natural type of landing is proposed west of the bridge on both the north and south side of 541' Street. Exact types, locations and configurations will be determined once the MCWD completes their evaluation of the modifying the grade control structure. Page 18 of 23 57 Feasibility Study 540h Street Roadway Reconstruction Improvement No. BA -416 October 21, 2013 Figure 13 — Possible Natural Creek Landing Type Based on feedback received, stakeholders prefer a natural looking bridge that they feel fits better into the neighborhood and complements the creek. A conceptual level bridge is proposed as part of this study. The actual type of bridge has not been determined. Staff recognizes several options exist regarding bridge aesthetics and associated lighting and railing elements. Staff is proposing,to gather additional stakeholder feedback on all these elements during final design. The bridge shown in Figure 14 is an arch structure with vertical sidewalls to accommodate the water flow and recreational use of Minnehaha Creek. This arch -type bridge was' generally preferred by stakeholders. It would span 42 - feet of clear width and provide for a 10 -foot wide access bench along the west side'; within the arch, The arch would be supported on piling. The bench wall is oW caintilevered sheet piling. The concrete headwall, wingwalls, and concrete railing base could incorporate a stone texture and coloring to match the local limestone. An ornamental metal railing could be mounted on the concrete traffic base at a safe height for pedestrians.

M Liahtmo Stakeholder feedback favored low impact downward -directed lights, which is dons'istent with established City lighting standards. Staff is proposing to gather additional stakeholder feedback on preferred light styles during final design. Public Utilities Water Main Since the existing trunk water main pipe is in satisfactory condition, reconstruction is not proposed as part of the project. New trunk water main pipe will be installed along 541' between Halifax Avenue and Park Place to loop the water main systems. By installing these pipes, the City will improve Page 20 of 23 59 Feasibility Study 64th Street Roadway Reconstruction Improvement No. BA -416 October 21, 2013 system pressures and water quality. Pipe installation will occur by horizontal directional boring to minimize the construction footprint and protect Minnehaha Creek. Sanitary Sewer Since the sanitary sewer trunk and service pipes east of Halifax Avenue are in satisfactory condition, no improvements are proposed. The Arden Park Area has a 24 -inch diameter clay sanitary sewer trunk pipe that follows the Minnehaha Creek corridor. This pipe may be part of a separate future City infiltration and inflow reduction project that Would include manhole repair and pipe lining by the cured -in -place -pipe (CIPP) method. Storm Sewer The project will install new concrete curb and gutter and a trunk storm sewer pipe and inlet system meeting State Aid minimum design standards to capture and convey stormwater. The project will install two (2) separate storm sewer catch basin manholes with 3 -foot vertical sumps and screens that will serve to catch sediment and debris from storm water runoff before it enters Minnehaha Creek. Based on stakeholder feedback, rain' gardens are generally supported by stakeholders to help treat storm water runoff before it enters Minnehaha Creek. Staff will determine exact locations of rain gardens near the creek once_.MCWD determines the creek's future configuration. Installation of sump drains will be installed where feasible to allow the property owners to. connect their. sump pump discharges directly into the storm sewer system: ,, Private Utilities -The local gas utility, company, CenterPoint Energy, has indicated that they. <: may upgrade or replace gas mains within the. project limits.] This work is not part of the City's. project `but,will be coordinated to occur prior to the start of const�`uction The City will coordinate other private utility relocations or upgrades prior to the startof construction. Any,, damage to privately -owned pet containment and irrigation systems caused by street and City utility reconstruction activities will be repaired by the City. RIGHT-OF-WAY & EASEMENTS: ' Existing right-of-way on all streets in the project area is 60 -feet wide. No ;additional right-of-way or easements are anticipated to complete the proposed improvements. PROJECT COSTS: The total estimated project cost is $X,XXX,000 and is summarized in Table 1. The total cost includes direct costs for engineering, clerical and construction finance costs from the start of the project to the final assessment hearing. Funding for the entire project will be from a combination of special assessments and State Aid and City utility funds. The estimated Page 21 of 23 t - Feasibility Study 50 Street Roadway Reconstruction Improvement No. BA -416 October 21, 2013 roadway_ _construction cost, including the bridge, sidewalk, and lighting is .roadway and will be 80 percent funded by State Aid funds; with the remainder funded by special assessments.

ENVISION'"' is a rating system for infrastructure developed in joint collaboration between the Zofnass Program for Sustainable Infrastructure at the Harvard Graduate School of Design and the Institute for Sustainable Infrastructure' ENVISION"' was created to support transformational, collaborative approaches that promote sustainable infrastructure development using a comprehensive, triple bottom line approach toward decision-making. It is Intended to foster a necessary and dramatic improvement In the performance and resiliency of physical infrastructure across the full economic, social, and environmental dimensions of sustainability. The rating system includes a total of 60 credits organized into five categories: • Quality of Life: Goal is to improve the project's impact an the surrounding community • Leadership: Goal is to strengthen collaboration, stakeholder involvement, and long-term planning considerations • Resource Allocation: Goal is to wisely manage materials, energy, and water resources used for project • Natural World: Goal is to understand and minimize negative environmental impacts of project • Climate and Risk: Goal is to minimize emissions and design for resilience - in both the short-term and long- term Within each credit, points are earned based on level of achievement obtained, with five levels of achievement ranging from "improved" to "enhanced" to "superior" to "conserving" to "restorative." The project was evaluated based on a set of 52 ENVISION'" credits which were determined to be most relevant to the 54"'street reconstruction and Arden Park Stormwater Management Plan. The ENVISION'" evaluation was conducted at three stages during the planning process. During the first stage, the project team identified ENVISION' credits deemed most relevant to the critical issues identified through stakeholder engagement including intercept surveys and door knocking. During the second stage the project team used ENVISION'" to evaluate the alternative design scenarios for each of the three project sections (West End, Middle Section, and East End). Results of this evaluation were presented at the September 30"' final scenario workshop and are provided in the appendix. Finally, ENVISION" was used by the project team to evaluate the preferred design alternative which is being presented as part of this report. Results of this evaluation are summarized in the figure below and in the appendix. The Institute for Sustainable Infrastructure is a not for profit education and research organization founded by the American Public Works Association, the American Society of Civil Engineers, and the American Council of Engineering Companies SEN 3 M overall, the preferred alternative scored 235 points out of a possible 687 points. It should be noted that the scores will increase substantially as the project moves from the feasibility phase to the detailed design and construction phases. At this stage of the project there was no basis to assign points to a large number of the credits available because decisions related to those credits have not yet been made. As can be seen in the point summary, the project scored relatively high in the Quality of Life and Leadership categories in particular. This reflects a number of factors including a very thorough stakeholder engagement program, a holistic planning approach that pro -actively considered infrastructure integrat*on opportunities, and the extensive efforts to design the project in a manner that will preserve community quality of life, promote alternative transportation modes, and preserve cultural and natural resources. 150 200 166 150 - a.+ Q rs. 100 50 0 QL Envision TM Scores M Unachieved Points 0 Total Points Earned 144 107 LD RA Credit Category /A SEH 188 NW 82 CR H yWhails.10111 4 67 intlroduction Project Backgromid The City of Edina is working hard to protect the environment for future generations — through programs and initiatives such as "Go Green Edina," the draft "Living Streets" Policy, the Edina "Emerald Energy Program" and participation in Minnesota's "Green Step Cities" program. The reconstruction of SA`h Street provides another opportunity for Edina to lead the way - by ensuring the project is designed and built In a manner that maximizes the social, economic, and environmental benefits of the project. To do so, the City is using ENVISION" - a sustainable Infrastructure rating system designed by the institute for Sustainable Infrastructure". The City has included sustainability evaluations in prior planning studies, and has used the three E's framework which provides an analysis of how a project performs In terms of Equity, Environment, and the Economy. The ENVISION'" analysis in this report is intended to provide the City with another option for conducting future sustainability evaluations on a wide range of project types. Purpose of this Report The purpose of this report is to summarize the results of applying the ENVISION"`" rating system to the 50, Street Reconstruction and Arden Park Area Stormwater Management Plan. The report includes an overview of how ENVISON"" was used at different stages throughout the project along with illustrative examples. It includes a more detailed summary of the final results of applying ENVISION"" to the preferred alternative. 'rhe ENVISION T" Rating System This unique new framework unites over900 sector specific systems into a comprehensive tool to evaluate and rate the community, environmental, and economic benefits of infrastructure projects. It was developed jointly by APWA, ACEC, and ASCE in partnership with Harvard University's Zofnass Program for Sustainable infrastructure. ENVISION"was created to support transformational, collaborative approaches that promote sustainable infrastructure development using a comprehensive, triple bottom line approach toward decision-making. It is intended to foster a necessary and dramatic improvement in the performance and resiliency of physical Infrastructure across the full economic, social, and environmental dimensions of sustainability. The rating system includes a total of 60 credits organized into five categories: Quality of Life, Leadership, Resource Allocation, Natural World, and Climate and Risk (Figure 1). Quality of Life credits are intended to improve the project's impact on the surrounding community. Leadership credits are design to strengthen collaboration, stakeholder involvement, and long-term planning considerations. Resource Allocation credits are intended to promote the wise use of materials, energy, and water resources. Climate and Risk credits encourage projects that minimize emissions and design for resiliency. 2 The Institute for Sustainable Infrastructure (1511 is a non-profit established by the American Public Works Association (APWA), the American Society for Civil Englieers (ASCE), and the American Council of Engineering Companies (ACEC) A SEH 'i (IU,�LI l Oi' LIFE I Purpose, Community, Wellbeing LEADERSHIP Collaboration, Management, Planning RESOURCE ALLOCATIO14 Materials, Energy, Water NATURAL WORLD Siting, Land & Water, Biodiversity 4,' t;LI�W�ttlt Emission, Resilience Figure 1 ENVISION Rating System Within each credit, points are earned based on level of achievement obtained, with five levels of achievement ranging from "improved" to "enhanced" to "superior" to "conserving" to "restorative," • Improved: Performance that is above conventional, but not by much. Encouraging, but mostly limited improvement in sustainable performance. • Enhanced: Sustainable performance that is on the right track but not particularly remarkable. Indications that superior performance is within reach. • Superior: Sustainable performance that is noteworthy, but falls slightly short of conserving. Point scores are designed to provide incentives for achieving conserving or restorative performance. • Conserving: Performance that has achieved essentially zero impact. May be combined with restorative If restoration is not applicable. • Restorative: highest level possible Methodology for Incorporating ENVISION'" into 4411" Street PI'oject ENVISION'"' was incorporated into the study in several different ways, each briefly described below, I)efining Relevant ENVISION'" Credits There are many different definitions of sustainability. One of the benefits of the ENVISIONT"' rating system is that it can provide a clear framework for defining sustainability at the project level. At the onset of the project, the project team including City staff reviewed the ENVISION"' credits and determined which were most applicable to the project. The intent was to help ensure consistent and clear communications and stakeholder engagement around sustainability. 52 of the 60 ENVISION'" credits were Identified as relevant to the project and summarized into a single document (See Appendix for 541a Street ENVISION" Credit List). The document was made available on the project website and shared with members of the project team. -A SEH .• Linking Credits to Key Issues for Component Workshop Following a rigorous stakeholder engagement process that helped identify key planning issues such as safety, aesthetics, creek issues, parking, signage, and traffic, the project team identified which ENVISION"" credits were most relevant to those issues. This analysis was used to help prepare materials for the August 19t4 Design Component Workshop. Figure 2 below shows one of the design component cards that were prepared for the workshop. At the workshop participants also received a brief explanation of the ENVISION" rating system and how it is being incorporated Into the project. { li&pdrnllp I TMA.

Similar to the Design Component Workshop, ENVISION'" was also incorporated into the September 30th Design Scenario open house. For each of the three sections, ENVISION'" was used to rate the alternative scenarios against each other. The results were summarized by credit category (Quality of Life, Leadership, etc...) and by total points scored and presented on large poster boards, Figure 3 below illustrates the Total Score for the Middle Segment of the project. A SEH 7 70 Figure 3 Total ENVSION Score Middle Segment Scenario #1 (raised bridge, retain whitewater features) outperformed Scenarios #2 (remove whitewater features, maintain existing vertical geometry) in terms of overall scoring. Scenario #1 scored higher in terms of quality of life — reflecting the extent to which stakeholders value the recreational and aesthetic qualit'es of the existing rapids. Scenario #1 also scored higher in terms of climate and risk credits, because it provides greater resiliency in the face of short-term hazards such as flooding. Scenario #2, on the other nand, scored higher in terms of Its potential impact on the environment, with greater opportunities for improving aquatic biodiversity, improving upstream water quality, and the overall ecological health of the creek.

For each credit, brief comments were made to support the level of achievement given. In addition, opportunities for improving the credit score were identified. Results Figure 5 presents a graphic summary of the total points achieved based on an evaluation of the preferred alternative presented In the feasibility report. Overall, the preferred alternative scored 223 points out of a possible 687 points. While the scoring shows a large number of unachieved points, it should be noted that the ENVISION" rating system was designed to push the boundaries of project design and therefore it was anticipated that most projects would not achieve anywhere close to a perfect score. For example, based on the preliminary scaring, the 54`" Street project would be eligible for a Silver Award through the Institute for Sustainable Infrastructure. 250 200 166 150 0 a. 100 5o 0 QL Envision T" Scores Unachleved Points ■ Total Points Earned 144 107 LD RA Credit Category 188 Figure S Overall ENVISION Scvre Preferred Alternative J'../► SEH NW 82 CR Mobcharls.cool) V 72 Table 1 below provides a breakdown of applicable points (reflecting total number of points available based on which credits were deemed relevant to the project), actual points earned, Innovation points earned, total points pursued, and percentage of available points.

John D. Chlebeck, PE Date: 10/22/13 Short Elliott Hendrickson Inc. 3535 Vadnais Center Drive Saint Paul, MN 55110 Lic. No.: 47125 83 84 Executive Summary The City of Edina is planning to begin construction on Water Treatment Plant No. 5 in 2017 per the current capital improvement plan. The facility would provide iron and manganese removal for Wells 5 and 18, through oxidation and granular filtration. A site has been selected near the City's existing water tower at 69th Street and France Avenue. This study was undertaken to evaluate the current timeline for construction of Water Treatment Plant No. 5, along with the hydraulic impacts to the distribution system of putting the planned facility online at the selected location. This study evaluates current supply and treatment facility capacity in comparison with existing and projected water system demands through 2030. In addition, impacts from the use of unfiltered wells such as Wells 5 and 18 are considered. This includes a review of well water iron and manganese concentrations in comparison with established regulatory guidelines for these naturally -occurring chemicals in drinking water. The City's existing water distribution system computer hydraulic model was used to evaluate the geographic extent of unfiltered water coming from Wells 5 and 18 during peak water demand conditions. Wells 5 and 18 both have iron and manganese concentrations that exceed the Secondary Maximum Contaminant Levels (SMCLs) for these chemicals. Iron in the wells is relatively low compared with other wells in Edina, but manganese is relatively high. The SMCLs are not enforceable regulations, but recommended standards to avoid aesthetic concerns in the water distribution system. These aesthetic concerns include taste and odor, discoloration, staining of laundry, and fouling of plumbing fixtures. In addition, the Minnesota Department of Health (MDH) has established Risk Assessment Advice for manganese, which provides recommended maximum concentrations to avoid potential neurotoxicity effects. Two values have been established by MDH, one for infants under one year of age, and a second for the remainder of the population. The manganese levels for Wells 5 and 18 exceed the guideline for infants according to water analysis from 2007. The City's four existing water treatment plants provide a total treatment capacity of 9.66 million gallons per day (MGD) for water supplied from eight wells. An additional ten wells provide water directly to the distribution system without filtration, and are used as needed to meet peak water demands typically encountered in the summer. By 2014, Wells 9 and 15 are expected to be connected to Water Treatment Plant No. 6, which will increase treated water capacity to 13.75 MGD. The planned addition of Water Treatment Plant No. 5 to provide treatment for Wells 5 and 18 will increase treated water capacity to 16.63 MGD. Average daily demands on the Edina water system have ranged from 6.8 MGD to 8.2 MGD over the previous ten years. Maximum daily demands have ranged from 13.1 MGD to 21.8 MGD over the same period. Supply and treatment facilities are often sized to meet maximum daily demands, with peaks in water usage over the course of a given day met by storage reserves. When the capacity of the City's water treatment plants cannot meet the daily demand during peak water use periods, the City currently utilizes unfiltered wells such as Wells 5 and 18 to make up the difference. A review of daily pumping records for the City indicates that it is typical for the City to utilize unfiltered wells to meet water demands approximately 120 days of the year. Population and associated water demands are expected to increase in Edina through 2030 and beyond. The 2010 recorded population of 47,941 is projected to increase to 51,500 by 2030. The corresponding potential maximum daily demand rate is projected to increase to 23.57 MGD by 2030. This is expected to increase the typical number of days with demand exceeding treatment capacity to 140 days per year given the existing treatment capacity. With the expansion of treatment capacity at Water Treatment Plant No. 6, and the planned construction of Water Treatment Plant No. 5, this is expected to be reduced to approximately 5 days per year. 85 Based on the analysis conducted for this study, it is recommended that the City maintain its current plan to begin work on Water Treatment Plant No. 5 in 2017. During preliminary design for the water treatment plant, the costs and benefits of increasing the capacity of Water Treatment Plant No. 5 should also be considered. Adding filtration capacity that could accommodate future wells could be a cost effective means to provide additional treated water capacity as water demands continue to increase, and might allow the construction of Water Treatment Plant No. 7 to be delayed for a longer period of time while continuing to meet water quality goals. The chosen site for Water Treatment Plant No. 5 also appears to be a good location for the plant from a hydraulic point of view. The water system hydraulic model indicates that the distribution system around the proposed location is equipped to handle potential flow rates from the facility.

The water from these wells varies in quality and chemical composition. The City has continued to add water treatment capacity to the water system as economically feasible, to make continued improvement to the quality of water supplied to its customers. The water treatment processes at the City's four existing water treatment plants function to address aesthetic concerns such as iron and manganese minerals from the well water, as well as health concerns such as those posed by radium and vinyl chloride. The City has been planning for some time to construct a fifth water treatment plant (Water Treatment Plant No. 5) to provide filtration for the water supplied from Wells 5 and 18 in the southeastern portion of the system. A site has been identified for this plant near the City's existing water tower on 69h Street and France Avenue. Raw water transmission main has been previously constructed, as it was convenient in conjunction with road improvements, to bring water from Wells 5 and 18 to this planned site. Wells 5 and 18 are currently used to provide water during peak summer demands. The wells contain levels of iron and manganese that exceed the EPA Secondary Maximum Contaminant Levels for drinking water. Secondary Maximum Contaminant Levels are recommended values for water constituents that cause aesthetic concerns in drinking water. They are not enforced, and are not based on health impacts. Iron and manganese are naturally -occurring minerals that are commonly found in Minnesota groundwater supplies. They are common sources of complaints from utility customers, causing taste and odor, laundry staining, and fouling of plumbing fixtures. Complaints in Edina have been kept to a minimum by limiting the use of Wells 5 and 18, along with other unfiltered wells on the water system. Water system operations staff maintain constant awareness of which wells are pumping, and need to frequently shift the sequencing of wells in the controls system to minimize impact from iron and manganese in the system. This has caused increased operational complexity while limiting the use of existing well infrastructure. It has also put additional burden on those wells that do pump to water treatment plants, causing some of these wells to be operated continuously throughout the year. This causes shortened equipment life expectancies, and reduces operational flexibility to regularly take equipment out of service for maintenance. M Current projections indicate a strong demand for high density and mixed use redevelopment in Edina over the next 20 years. Much of this redevelopment activity is expected in the southeastern portion of the City, which is served by Wells 5 and 18. There is concern that with planned growth, the accompanying increase in water demand will cause a need to utilize Wells 5 and 18 more frequently. Therefore, it will be more difficult over time to maintain system water quality through operational adjustments. This study examines the City's current use of unfiltered well water and the potential impacts within the distribution system. In addition, projected growth in water demand and water use patterns are presented in order to quantify how the use of Wells 5 and 18 will increase and how additional use will impact the water system and its customers. The study aims to clarify the rationale used in deciding when to construct the planned Water Treatment Plant No. 5. Additional distribution system hydraulic analysis was also conducted as part of this study to further evaluate the current plan to construct Water Treatment Plant No. 5 at the 69h Street and France Avenue site. 89 2.0 Water System Supply and Treatment Facilities The City of Edina's water supply is provided by a network of wells and water treatment plants that are distributed throughout the City. The wells provide groundwater from two aquifer systems: the Prairie du Chien - Jordan system and the Mount Simon - Hinkley system, with the majority of the City's water supply coming from the Prairie du Chien - Jordan aquifer system. Water is processed at four existing water treatment facilities. Plants 2, 3, and 4 are filtration plants that are designed primarily for the removal of iron and manganese through oxidation and granular filtration. Plant 6 is the most recent addition to the system. This plant was designed to remove vinyl chloride that was impacting Well No. 7. Vinyl chloride is a contaminant that entered the aquifer from activities at the land surface, and a plume of the chemical was migrating into Edina from an unknown source in St. Louis Park. The treatment process at Plant 6 includes air stripping which effectively removes vinyl chloride from the water supply. The plant also contains facilities for radium removal, and will be used to treat water from Wells 9 and 15 in the near future. These wells contain radium from natural sources, and are currently on emergency reserve status. A summary of well and treatment capacities follows in Table 1.

The EPA has set Secondary Maximum Contaminant Levels (SMCLs) for both of these minerals. SMCLs are established as guidelines to assist public water systems in managing their drinking water for aesthetic considerations such as taste, color, and odor. These contaminants are not considered to present a risk to human health at the SMCL. Therefore, these standards are not regulated or enforced by EPA or the Minnesota Department of Health. Iron and manganese are both common causes for customer complaints at water utilities in Minnesota. Complaints are typically related to staining or fouling of plumbing fixtures. Taste and odor can also be a concern with iron or manganese above the SMCL. In addition to aesthetic issues, more recent research by the Minnesota Department of Health (MDH) indicates there may be potential health impacts due to the consumption of manganese in water at high concentrations. In 2011, MDH began a review of recent human and animal studies related to manganese exposure. Based on that review, a tiered manganese guidance was issued for drinking water in 2012. This guidance established a Risk Assessment Advice for manganese concentrations of less than 0.1 mg/L for infants less than one year of age, and less than 0.3 mg/L for children greater than one year of age and adults. Manganese is a known neurotoxin at high concentrations. MDH has established the Risk Assessment Advice to protect populations from nervous system damage. The levels are not regulated at the current time, but are recommendations for human consumption based on a review of manganese exposure research. Additional information on MDH and EPA health advisories related to manganese can be found on the MDH website: http://www.health.state.mn.us/divs/eh/risk/guidance/ wg /manganese.html Table 2 lists the iron and manganese levels measured in Edina's wells in 2007, along with the SMCL for each. 91 Table 2 Iron and Manganese Concentrations in Edina Wells *Currently unfiltered Table 2 indicates that all of the water sources in Edina have iron levels that exceed the SMCL, and most have manganese levels that exceed the SMCL. Through the City's current filtration processes, many of the problems that could result from these mineral concentrations have been mitigated. However, current filtration capacities do not meet all water demand conditions on the system. Wells 5 and 18, for which treatment is planned with Water Treatment Plant No. 5, have similar levels of iron and manganese as measured in 2007. Both wells are on the lower end of the spectrum for iron levels, but have relatively high manganese levels.

The total water use in 2010 was 2,478,000,000 gallons. This results in an average daily (AD) demand rate of 7.61 million gallons per day (MGD). On a per capita basis, the water use in Edina in 2010 averaged 142 gallons per capita per day (gpcd). Water demand comes not only from residential sources, but also from commercial, industrial, and institutional land uses. However, where the relative proportion of these land uses remains fairly constant, it is a sound assumption that the water use per capita will also remain constant. Per capita water demand has ranged from 142 gpcd and 171 gpcd between 2003 and 2012. For future water use projections of AD demand, a value of 171 gpcd is used in this study. This value is representative of the highest of the previous ten years. Using the highest expected per capita demand is a common practice in utility infrastructure planning, to ensure that future budgets are adequate to meet potential needs of the system. Maximum daily (MD) demands, representing the highest daily water use on the system over a given year, are often of greater interest to utility planners. This is because supply facilities typically need to be able to meet MD demands reliably in order to provide continuous water service. The per capita MD demand has ranged from 274 gpcd to 458 gpcd between 2003 to 2012. The fluctuation is typically correlated to climate parameters, such as precipitation and temperature. This is due to the fact that the majority of peak water use serves lawn irrigation, especially in suburban communities. For future water use projections of MD demand, a value of 458 gpcd is used in this study. The historic per capita water use for Edina over the last ten years is presented graphically in Figure 1. There is a slight downward trend in per capita water use in Edina over the last ten years. However, it is unclear if this is related to normal climate variation, or if it is indicative of changes in water use behavior.

Based on the assumptions discussed previously of a constant per capita average day demand of 171 gpcd and a per capita maximum day demand of 458 gpcd, the potential maximum day demand rate is projected to increase to 23.57 MGD by 2030. This is represented graphically, along with historical water demands of the previous ten years, in Figure 2.

This projected population growth is not considered likely by City planners. It is mentioned here, however, as a possible outcome. If population was to increase to that level by 2040 by a linear growth trajectory, the projected population for 2030 would be 62,953 rather than 51,500. This outcome could result in a maximum daily demand of 28.8 MGD as compared to the 23.6 MGD projected in this study. It is recommended that these projections are revisited in five years to reevaluate the population trajectory of the City. 94 5.0 Filter Plant Capacity Evaluation The capacities of existing wells and water treatment plants were listed in Table 1. Future planned water treatment plant capacities are presented in Table 3. The existing plant capacity of 9.66 MGD will be increased by 2014 to 13.75 MGD with the addition of Wells 9 and 15 to Water Treatment Plant No. 6. Water Treatment Plant No. 5 is currently in the City's capital improvement plan for 2017, with an estimated start-up date of 2019. The total treatment plant capacity with the addition of Plant 5 would be 16.63 MGD. With the future construction of Plant 7, the total plant capacity would rise to 20.95 MGD.

With the existing water treatment capacity, a certain amount of water is supplied from system wells such as Wells 5 and 18 during peak summer demands, which provide unfiltered water to the system. The previous three years of daily pumping data from all of the wells was analyzed to evaluate the frequency of use of unfiltered system wells. Figure 3 shows a graph of the daily pumping data along with AD demand and MD demand for each of the three years for which data were available.

The number of days each year in which demand exceeds plant capacity is clearly related to the maximum daily demand and the level of peak season water usage. Table 4 lists the number of days exceeding plant capacity, along with demand parameters for each of the three years. Table 4 Summary of Daily Pumping Data No. of Days Percentage of Demand Days Demand Estimated Per Estimated Per Exceeded Exceeded Plant AD Demand MD Demand Capita AD Capita MD Year Plant Capacity Capacity (%) (MGD) (MGD) Demand (gpd) Demand (gpd) 2010 57 15.6% 6.789 13.13 141.6 273.9 2011 96 1 26.3% 6.910 14.12 1 142.8 1 291.8 2012 123 1 33.6% 7.614 17.08 1 155.9 1 349.8 M Of the three years for which daily pumping data were available, 2012 is viewed as a more typical year - with a per capita MD demand closer to the 10 -year average of 360, and a per capita AD demand closer to the 10 -year average of 154 gpd. For this reason, the daily distribution of water demands for 2012 was used as a model for future years. The total daily water demand for each day in 2012 was divided through by the average daily demand for the year, thus producing a demand multiplier for each day of the year. These daily multipliers can then be applied to future projected values of average daily demand in order to estimate the number of days in future years that are expected to exceed the water treatment plant capacity. The results are shown in Figure 4.

With the planned connection of Wells 9 and 15 to Water Treatment Plant No. 6, this is expected to drop to about 41 days in 2014 (11% of days) and range up to 46 days by 2030 (13% of days). With the construction of Water Treatment Plant No. 5 to provide iron and manganese removal for Wells 5 and 18, the days 97 with demand exceeding plant capacity drops further to about 5 days per year (1% of days). The ultimate plan to construct Water Treatment Plant No. 7 for the treatment of Wells 16, 19, and 20 would allow the City to meet nearly all demand conditions projected through 2030. Figure 5 presents another perspective on the water treatment capacity. Many communities set the goal of meeting maximum day demands with their water treatment plant capacity, thereby allowing all water provided to the distribution system to be filtered.

Water Treatment Plant No. 5 is currently on the City's capital improvement plan for 2017, which could allow the plant to come online in 2019. M 6.0 System Impacts from Pumping Wells 5 and 18 In order to gain an understanding of the geographic extent of impacts of the use of Wells 5 and 18 in the distribution system, the City's existing computer hydraulic model of the distribution system was used to run a source trace analysis under a series of peak demand days. The source trace calculates the amount of water at any node in the distribution system model that comes from a given source of supply. In this case, the sources of supply tracked were Wells 5 and 18. Figures 6 and 7 show the results of this analysis. The geographic distribution of water from Wells 5 and 18 is dependent on system hydraulic parameters such as the demands assigned geographically throughout the network, the hydraulic properties of the well pumps, the pipe sizes in the water main network, and the location of other supply or storage facilities. As water use fluctuates over the course of a day, the distribution of water from these wells will expand and contract. The results presented represent the maximum distribution over three days with maximum day demands on the water system. 3� E4, �E Legend ■ Well a Water Storage Tank % of Water from Well 5 • 0-10 • 11-20 • 21-30 31-40 • 41-50 • > 50 Water Tower )II 18 ThN map NnaXNr Np.ry nmNed map nor•eurwY map oral'srW nluided[oMwed xoro.

First, the distribution system will need to handle greater flow rates from the location of the new water treatment plant. This tends to cause greater frictional energy losses in the distribution system, and to increase pressures locally around the water treatment plant location in order to overcome the greater frictional losses. Second, with the addition of Water Treatment Plant No. 5, the City will want to utilize this facility to a greater degree than current Wells 5 and 18 due to improved water quality. The wells and plant high service pumps will be placed higher in the priority list for use. This could create a concern due to the plant's proximity to the Southdale water tower. The water produced by Water Treatment Plant No. 5 will tend to fill the Southdale tower quickly, which could cause the other towers on the system to lag the Southdale tower. The existing computer hydraulic model of the distribution system was used to evaluate the hydraulic impacts of operating the new water treatment plant at the planned location. The first concern of increased distribution system pressure is easily evaluated in a hydraulic model. Pressures in the distribution system around Southdale were examined in the model with the existing system and with the proposed system after Water Treatment Plant No. 5 is added. Both scenarios were run with average day demands on the system, with water towers at 2 feet below overflow, with the high service pumps at Water Treatment Plant No. 6 producing about 2600 gpm, and with Well 4 on at Water Treatment Plant No. 2. The new water treatment plant was modeled as an input to the network of 2000 gpm at the intersection of 69h Street and France Avenue. The comparison is shown in Figure 8, with pressures at model nodes shown in psi. Due to the proximity of the Southdale tower, the distribution system frictional losses are minimized at the planned location for Water Treatment Plant No. 5. It can be seen in Figure 8 that pressures in the vicinity of the water treatment plant can be expected to increase around 1-2 psi with the additional pumping at that location. Evaluation of the effect on hydraulic balance of the water towers on the distribution system is a little more difficult as it depends on many factors such as the geographic distribution of system demands and on the accuracy of pump controls. Most often, it is during peak demand conditions that tower balance becomes a concern. This is because there is a greater amount of water being moved through the distribution system from supply sources and storage facilities to points of use. Under these conditions it becomes more difficult to push water long distances, and towers tend to drain quickly during periods of the day when demands are highest. Therefore it becomes difficult to keep some towers full without overflowing other towers under these conditions. 102 Figure 8 — Distribution System Pressure Impacts of Water Treatment Plant No. 5 SOIOMOAIE 103 For the purposes of this analysis, a typical peak operation control scheme for the well and water treatment plant high service pumps was obtained from the City. This was input into the model to control pumps in an extended period simulation (EPS). The model was run for three consecutive days, with average July water demand, to evaluate tower levels over time. Water Treatment Plant No. 5 was placed in the pump sequencing as the last water treatment plant to be run, but before any unfiltered wells were used to maintain water tower levels. The comparative EPS results are shown in Figures 9 and 10. Due to the distribution of water demand in the model, the Southdale tower is drawn down faster than the other towers during peak demand periods. This is apparent in Figure 9. Because the Southdale tower is lagging the other towers in the existing condition, the addition of Water Treatment Plant No. 5, and the increased pumping at that location actually helps with tower balance. Figure 10 shows the results of the EPS with the addition of Water Treatment Plant No. 5 to the model.

These costs are based on projects of similar scale and scope completed by SEH recently. These preliminary numbers are conservative, with a high level of contingency due to unknowns about the site and project -specific requirements. It is recommended that the City review planned expenditures in the current capital improvement plan, as construction costs for water treatment plants have increased significantly in the last two years. Table 5 Preliminary Cost Estimate for Water Treatment Plant No. 5 Item Cost Estimate Construction Cost Estimate (3 MGD Pressure Filter Plant) $4,800,000 Contingency (20%) $960,000 Engineering, Administrative, and Legal (20%) $1,152,000 Total Estimated Project Cost $6,912,000 106 9.0 Conclusion Water system operations personnel have been successful in minimizing complaints on the Edina water system. However, they have reported difficulty with current operations, requiring constant vigilance in ensuring that the use of system wells, which are currently not filtered, is minimized during the summer season. Examination of prior pumping records shows that there are a significant number of days each year in which water system demands exceed the capacity provided by the City's existing water treatment plants. In addition, the wells that are currently sent to filtration plants are being over -utilized, limiting operational flexibility, reliability, and equipment life expectancy. The City of Edina has set a goal of continuing to improve on the existing water quality and operational constraints through the expansion of water treatment plant capacity where it is economically feasible, ultimately eliminating the need to pump unfiltered well water into the distribution system under most demand conditions. With projected population and associated water demand increases in Edina over the next 20 years, additional water treatment plant capacity will be needed to meet this goal. The current plan to add two additional wells to Water Treatment Plant 6 by 2014 will help the City to reduce the number of days under which filtration capacity does not meet demand by about 60%. Water Treatment Plant No. 5 has been planned for some time, to filter water from Wells 5 and 18. This facility is on the current water utility capital improvement plan for 2017. The additional filtration capacity provided by Plant 5 will further reduce the need to pump unfiltered water into the distribution system, providing filtration capacity to meet approximately 99% of demand days. Hydraulic analysis indicates that the planned location for Water Treatment Plant No. 5 will allow the planned facility to pump greater than 2000 gpm to the distribution system without negative impacts on system pressures or hydraulic balance. The proximity to the Southdale water tower limits frictional backpressure at the proposed facility location. Modeling of system operations with the new facility indicates that the proximity to the Southdale tower will also help to keep that storage tank full during peak demands. Therefore, the proposed location appears to be hydraulically feasible without significant distribution system modifications. Based on the results of this analysis, it seems as though the current plan to begin construction in 2017 for Water Treatment Plant No. 5 is a sound course for the City to continue to make progress on the improvement of water quality and system operations. While there has been discussion about the construction of a future Water Treatment Plant No. 7, to provide treatment for Wells 16, 19, and 20, a date has not been established for that facility. During the feasibility study phase for Water Treatment Plant No. 5, consideration should also be given to building additional treatment capacity into the plant - to expand treatment to other future wells in the vicinity of the plant. While this study looked at water demand projections through 2030, prior planning documents have indicated the potential for redevelopment activities to continue to increase the population of the City of Edina beyond the values considered here. The most recent preliminary population projections from the Metropolitan Council also indicate a potentially higher rate of population increase in Edina. With continued growth in the City, there will be additional needs for water treatment capacity. This added capacity might be built more cost effectively in conjunction with Water Treatment Plant No. 5 as opposed to additional facilities in the future. Additional capacity at 107 Plant 5 may also allow the City to delay the construction of Plant 7 further, while achieving the same water quality results. jdc
