Motion carried unanimously. IV. ADOPTION OF CONSENT AGENDA A. Minutes. No Comment. B. Attendance report and roster. No Comment. C. Workgroup list and minutes. Member Anderson requested the Student Working Group be renamed to Student Environmental Leadership Council. Motion made by Member Gubrud and seconded by Member Zarrin to approve the Consent Agenda with student working group being renamed. Motion carried unanimously. V. COMMUNITY COMMENT. No Comment. VI. REPORTS AND RECOMMENDATIONS> A. Vision Edina. Karen Kurt, Assistant City Manager, presented a broad based community visioning process of what Edina will look like in 20yrs. There are four plausible scenarios which are Reinventing Tradition, Nodes and Modes, Complete and Connected and Edina Today Extended. These scenarios are along a horizontal axis of Balancing Edina's Redevelopment and the vertical axis of Community Fabric and Character. The proposed Vision Statement is "Edina holds a well-earned reputation as a city of choice. It is the model of a successful, mature and progressive urban community, which remains relevant in a modern and changing world. We maintain our heritage and attractiveness, and afford our residents the highest quality of life, while actively embracing the future. Within the context of the North America and the Twin Cities, Edina is known as a distinguished location that provides the ideal environment to raise families, run businesses and simply enjoy life." The City Council will approve Vision Edina in May 2015. B. Regional Indicators Initiative. Becky Alexander, Designer, LHB Inc. gave an update on Edina's use of Energy, Potable Water, Travel, Waste, and Greenhouse Gas Emissions from 2007-2013. Minnesota Pollution Control Agency's GreenStep Cities Program of 28 best practices helps the City track their energy usages within their City Limits. Edina's Weather Normalized Greenhouse Gas Emissions per capita emissions is 11% higher than the Regional Indicators Initiative. Edina's per capita costs are 20% higher that the RII. The Edina can use project estimates of population, household and jobs to create a Business As Usual line and compare it to a Target Goal of Reduction through a wedge diagram template. C. Home Energy Squad. Stacy Boots Camp, Center for Energy and Environment, gave an update on Home Energy Squad Enhanced. The company wants to help people save money on energy and improve the comfort in their homes. They have been in Edina since 2010 and partnered with the City in 2013. Over 400 homes have participated in the program. If a home has an Energy Fitness Score of 96 or higher they receive an Energy Fit Homes Certificate and they get recognized on MLS when selling their home. D. Recycling and Solid Waste Annual Summary. Solvei Wilmot, Recycling Coordinator, reviewed what materials can be collected. The Minnesota Pollution Control Agency's Metropolitan Solid Waste Management Policy Plan 2010-2030 established a solid waste management goal of 45% recycling recovery and 3% organics recovery to reduce the amount of materials entering a landfill. In 2014, the Minnesota Legislature expanded the recycling requirements. Commercial buildings in the seven -county metro area that generate four cubic yards or more of trash per week must begin recycling at least 3 (three) materials by January 1, 2016 (MN Statute 115A.151) Edina is currently at 43% recovery and it has substantially increased since Business Recycling has started. The Energy and Environment Commission is taking a look at what can be done to capture organics. Currently, the refuse haulers may provide the service should a resident request organics collection. If the refuse hauler does not provide the service, a citizen may check with other companies to find that service. E. Energy Annual Summary. Ross Bintner, Environment Engineer, gave an update on the City Hall Solar Panels produced 17.66Mwh and Grandview Tire, a similar sized system funded by the EEEP, produced 34.66Mwh. City Hall does have one bad inverter. City Hall's solar panels were installed in Fall and Grandview Tire's was installed in Spring of 2012. The EEC would like the Solar Panels to be inspected and to find out why they are underperforming. The Electric Vehicle has about 5,700 miles of usage in its first year. The Electric Vehicle is comparatively a highly used vehicle in the engineering and building department inspection fleet. The B3 data shows Public Works as being the most energy efficient building. A lot of our Buildings rank in the bottom 20% with 33% of our buildings in bottom 10%. Public Works and Braemar Arena have the biggest square footage.. F. Annual Purchasing Policy Report. Acting Chair Kostuch said the Commission is waiting for the 2014 report from staff. G. 2015 EEC Workplan. Acting Chair Kostuch reviewed the 2015 Workplan with the main focus on Energy Conservation. The Commission will be discussing their Workplan with Council in April. H. Discussion of April Work Session with Council. Member Sierks reviewed the presentation for the Council Work Session.The meeting will discuss how the City can achieve the greenhouse gas reduction goals that are in chapter 10 of the comprehensive plan. VII. CORRESPONDENCE & PETITIONS. No Reports. VIII. CHAIR AND COMMISSION MEMBER COMMENTS. Acting Chair Kostuch welcomed the three new Commissioners; Richard Manser, Lauren Satterlee and Melissa Seely. He also thanked Dianne Latham who has been termed off. A. Building Energy Efficiency Subcommittee. Member Sierks discussed the increasing energy efficiency of City buildings has been EEC's top strategy for 3yrs. Tim Barnes, Facility Manager, will help to focus on deeper energy efficiency. Time and financing are what's holding the projects back. B. Business Recycling Working Group. Member Zarrin encourages Businesses to contact Hennepin County to help them get started with a recycling program. More than half of the total waste in the County comes from Businesses and nearly two thirds of that can be recycled. Hennepin County offers grants, signage, technical assistance and case studies to help business and organizations start or improve recycling programs. 501h & France, International Dairy Queen and Minnesota Lice Lady have received grants. Edina Cinema, Edina Grill and Salut have been recognized by the County for recycling and organic wastes. C. City Environmental Considerations Subcommittee. Acting Chair Kostuch explained how the committee created a one page document to be completed with each Capital Improvement Project by explaining how their project has environmental efficiency. A third of the projects addressed environmental considerations, a third needs improvement and a third didn't have any environmental considerations. D. Community Solar Subcommittee. Member Sierks explained what Community Solar is and proposed that the City might act as a host and residents can purchase panels or shares to receive credits on their electrical bill. The project will need staff and Council commitment in order to be successful. E. Education Outreach Working Group. Member Thompson reviewed the 2014 accomplishments which were 3'd Annual Forum "What Will Turn You on in 2030?", 5th year participating in July 4th Parade "Edina a Deeper Shade of Green", and Edina Day of Service doing Home Energy Squad visits. Member Howard reviewed the Films Series showings of "Chasing Ice", "More Than Honey", "Bag It" and "Troubled Waters: A Mississippi River Story". "Cowspiracy" will be shown April 17, 2015 in the Council Chambers. Member Thompson announced the 4th Annual Forum "Here Comes the Sun" on April 8th with Keynote Speaker Paul Douglas. F. Home Energy Squad Subcommittee. Member Gubrud said the Home Energy Squad is a program for reducing residential energy usage and GHG emissions in Edina. It's proven awareness and action initiatives. Publicity and financial incentives are essential for success. There have been 401 visits since 2010. G. Local Food Working Group. Dianne Latham, Chair LFWG, reviewed the group's two goals. They wanted to change the Apiary Ordinance to allow honey bees and the Livestock Ordinance to allow Hen/Chicken keeping. The second reading for both ordinances will be March 17th H. Recycling and Solid Waste Working Group. Member Zarrin thanked Dianne for Chairing the Working Group for many years. Member Zarrin would like to add composting to recycling. L Student Subcommittee. Member Anderson explains the Student Environmental Leadership Council (SELC) is to bring students together in the Community to work on promoting green initiatives and allow better communication between environmental groups in the schools, EEC Education & Outreach Working Group and Council. Students in SELC are from Edina High School Project Earth, South View Middle School Environmental Group and Valley View Middle School Environmental Action Now Group. Member Padmanabhan said the students are helping with the April Forum event. J. Urban Forest Task Force. Dianne Latham said the EEC passed the ordinance and now the Park Board is reviewing it. They adopted the Emerald Ash Bore proposal. They also adopted the change to the ordinance on boulevard trees. The section 36 changes were forwarded to the Planning Commission. The Living Streets initiative was forwarded to the Transportation Commission. The Green Steps Cities best practices were tabled to their working group on urban forest task force. The recommendation to adopt Minneapolis's park board do not plant list was tabled to their work group. Certifying selected city parks as autobahn cooperative sanctuary was tabled to their strategic plan. Buckthorn maintenance will follow up with a maintenance plan was tabled to their strategic plan. The garden council will help cleanup buckthorn in Bredesen Park. The tree preservation ordinance was passed by council. K. Water Quality Working Group. Member Waddick said there are six Master Water Stewarts in the Working Group. Storm drain stenciling and passing out door hangers to educate citizens on what improper run off does to our water system was a priority in the Summer. During Winter, they do salt usage outreach by passing out two flyers, Residential Snow and Ice Care and Winter Maintenance Hiring Someone. Also, outreach to Arden Park houses along creek to install buffers. Acting Chair Kostuch thanked Ross Bintner and Rebecca Foster for their staff support. IX. STAFF COMMENTS A.

Tuesday, March 10, 2015 WQWG members in attendance: Catherine, LouAnn, Sue, John & Steve EEC Environmental outreach movie is scheduled "Cowspiracy" the impact of cattle raising 7:00 p.m. 3,' Thusday in April (April 17,") at City Hall in Edina. John Howard gave the information. EEC Forum (4," annual) education and outreach Wednesday, April 8'" @ 6:00 is the Action Resource Center and the program is @ 7:00 p.m. Key note speaker is Paul Douglas. Located at the Fick Auditorium Edina High School. Storm drain stenciling program: Julie Bascom (Service -Learning -Coordinator) was re -contacted by Steve and Julie said that she was going to get the teachers to say when they will want to conduct the "train the trainer's" training session. Waiting on Julie to respond to when the teachers want to schedule that training session. It will either be before the school day or after the school day, per Julie. More specifics to follow. We need to alert Laura Adler about getting additional stenciling kits. How to get the word out to kick-off another stenciling campaign: Nextdoor.com both for our own neighborhoods and for the City to put out an announcement (Leaves, garbage, sediment, storm drain in your neighborhood- Sue said she would forward her writing on this to us. Sue said that she would contact the Edina Boy Scouts Master. High School outreach hours for environmental work. Catherine said she'd call the High School. Sue needs a little training on how to present the stenciling program when Sue meets with the Boy Scouts. Sue suggested to have some way to have a `gauge' for people to see what progress we're making with stenciling the storm sewers. Certificates for the storm sewer stenciling participants was discussed as an important policy to continue and that when the 4" grade class participates we'll need many more of them. Sue also shared her draft for public outreach communication that answers questions about the stenciling campaign and motivates the reader to action. Noticeable amounts of excess salt (chloride/snow melt) was in the parking lot and on the walk ways of the City hall property. The WQWG found this ironic considering our current chloride reduction outreach campaign to help educate the public on proper chloride use. Sue went out to the City Hall parking lot and took photo's of the excess. We're going to submit the photos to Laura Adler and Ross Bitner. LouAnn will do the follow-up to see if the salt can get swept up before the next rains come and dissolve the salt into stormwater run off. Sue shared a project that she and her husband (Randy) initiated at their church. The contractor spread a huge amount of salt that far exceeded the necessary amount needed for the church property. Sue and Randy organized others to put in a significant effort to bag the excess salt that was on the church parking lot property. Sue had photo's to share what their salt clean up project entailed. Arden Park outreach. Becky Christopher at Minnehaha Creek Watershed District said that Becky would get back to LouAnn regarding Project 14 (target neighborhoods along the creek to install `riparian buffers' for the creek bank) and come up with a new project, "Project 15" along the lines of project 14. List of names and addresses sent by Becky said to start with the list. Becky sent the home owner list to Louann. Louann will meet with Becky and Laura D. at the district watershed office on March 18th. Sara Moran is getting a neighborhood association set up in Arden Park. Carl Malmquist is maybe interested in getting involved. There are other (non -Arden Park residents) who are interested. Language in the flyer would include that the City `supports' the idea of a "project 15"? Sue suggested that the meeting could be at St. Stevens Church if getting a meeting at someone's home doesn't pan out. LouAnn said she would contact the City to find out when we can get fliers. Sue and Steve Brown might be a possible contact. Jennifer Benerotte & Crystal Caron said to go through Laura Adler for city communications in: Utility bills (twice per year maybe, cleaning storm drains, mow high etc.) Sun Current Edition Edina (supplement) and About Town. LouAnn called Jennifer to follow-up. Rebecca Foster From: Karin Schaefer <karin@mnbeef.org> Sent: Friday, March 27, 2015 10:34 AM To: Ross Bintner; James Hovland; Kevin Staunton; swensonannl@gmail.com; Robert Stewart, Mary Brindle Subject: Rethink "Cowspiracy: The Sustainability Secret" Dear Mr Bintner and the City of Edina's Leadership: I was disappointed to hear that your public entity has agreed to show and promote an inaccurate movie, called "Cowspiracy: The Sustainability Secret." My family and I raised beef cattle in Wright County. I also work for Minnesota's 18,000 beef farmers and ranchers through the Minnesota Beef Council. Our organization is charged with correcting misconceptions of the general public about how cattle are raise and beef's role in a healthy diet. It says on your webpage that you will have a discussion after the movie. Have you thought about including an actual beef farmer or rancher in on that discussion? Have you considered a registered dietitian or University of Minnesota professor? Have any of your City's staff or leadership actually visited a real life, working farm or ranch? Though I am sure your city does not have "active' farms within its borders, farms in Minnesota do feed your residents. Farmers in out -state MN do visit Edina to shop, eat and in my case, give birth to our children in your hospitals. Too often, people who know nothing about agricultural topics, sciences and technologies are making critical decisions or making public judgments about our industry. SEEK FIRST TO UNDERSTAND! I have included facts below that may encourage you to reconsider this one sided documentary. o The entire premise of the film, that the U.N. FAO report Livestock's Long Shadow proved that cows are causing global warming is flawed. That is NOT the conclusion of the report. Even the statement in the introduction to the report that global livestock production generates more greenhouse gasses than transportation, has been recanted by the lead author, Dr. Pierre Gerber. ■ Livestock's Long Shadow looks at the impact of ALL livestock production, globally, specific to greenhouse gas emissions. One major source discussed in the report is deforestation in the Amazon, which the report concludes is responsible for 1/3 of the GHGs attributed to livestock production. ■ We are not deforesting in the United States to make room for cattle grazing or feed crops because we developed a production model that reduces the amount of land and feed required to produce a pound of beef. In fact, we are increasing forest acreage. ■ A more recent UN FAO study, published in 2012, documented a global reduction in GHGs from livestock since the original study (from 18% to 14%) and pointed to two key areas for further improvement: feed efficiency and animal health. These are the key strengths of the U.S. beef production model, which many experts agree is the model for global livestock production. o Cattle are not a major source of greenhouse gas emissions in the United States. In fact, their contribution to global warming is much less than most people think. According to numbers from the Environmental Protection Agency (EPA), cattle production is not a top contributor to greenhouse gas emissions. ■ According to the US Environmental Protection Agency in 2011: ■ All of Agriculture= 6.9% of total US greenhouse gas emissions. ■ All Livestock=3.1% of total US greenhouse gas emissions. ■ Methane from all livestock=2.8% of total US greenhouse gas emissions. ■ Methane from beef cattle= 1.5% of total US greenhouse gas emissions. ■ To compare with other industries: ■ Electricity Generation = 33% of total greenhouse gas emissions. • Transportation = 26% of total greenhouse gas emissions. ■ Industrial Use = 11% of total greenhouse gas emissions. ■ Residential and Commercial Use = 8% of total greenhouse gas emissions. The beef community agrees that taking care of the environment is very important. Cattlemen and women believe beef and the environment can exist together without damaging it. ■ The beef industry completed a first -of -its -kind sustainability and life cycle assessment (LCA) - certified by NSF International - that provides benchmarks on its economic, environmental and social contributions in the United States and a roadmap for the journey toward more sustainable beef. This research examined the sustainability of the entire US beef supply chain from pasture to plate and beyond, also examining the impact of food waste on sustainability. ■ After two years of data collection and research, the beef community has proven it's on the right path forward with a 7 percent improvement in environmental and social sustainability from 2005 to 2011. Innovation and enhancements in management and practices have led to some major improvements in US beef sustainability, such as: ■ 32 percent reduction in occupational illnesses and accidents ■ 10 percent improvement in water quality ■ 7 percent reduction in landfill contributions ■ 3 percent reduction in water use ■ 2 percent reduction in resource consumption and energy use ■ 2 percent reduction in greenhouse gas emissions Karin Schaefer Executive Director Minnesota Beef Council Office: 763-479-1011 E-mail: karin@mnbeef.org Visit us on the web: www.mnbeef.ora f in T J DATE: March 3, 2015 TO: Mayor and City Council CC: Scott Neal — City Manager, FROM: Chad Millner PE — Director of Engineering, Brian Olson PE — Public Works Director RE: 2015 State of the Utilities This memo reviews notable accomplishments for 2014, upcoming utility projects and initiatives for 2015 and future opportunities. Executive Summary The City of Edina water, sanitary and stormwater public utilities provide critical public health, sanitation and public safety services. These utilities operate over generations, continuously providing reliable service to every Edina resident and business. Given their high reliability public utilities are generally out of sight and out of mind, but these services rely on aging infrastructure components that occasionally fail. The 2015 "State of the Utilities" report is meant to continue to tell the story of the people, equipment and infrastructure that support these core public services. Utility services are primarily provided by physical infrastructure including extensive pipe networks, pumps, reservoirs and electronic control systems, and are dependent on and constrained by energy and natural water resources systems and available financial and human resources. The fundamental challenge can be easily summed up - the infrastructure providing utility services are aging. While continual repair and renewal of this infrastructure is taking place, it is sometimes reactionary. This issue of aging infrastructure challenges utility operators and engineers to continually improve operations and maintenance, and, design and construction techniques to protect, extend the life and renew or replace utility infrastructure. In addition to the information provided in this memo, the 2015 Water, Sanitary and Stormwater Utility System Report provides a more detailed summary of utility services and reflects the state of the practice in managing city utilities to sustain the existing service, and plan and react to short term risks and emergencies and long term trends in service demand. Accomplishments Last year saw the sanitary and storm sewers challenged as a significant June rainfall event compounded with an already wet spring resulted in an overwhelming volume of requests for service for flooding, wet basements, and surcharging sanitary sewers. Although Public works pre -staged 11000 sandbags flows in Minnehaha Creek hit all-time records resulting in over 150 calls for service over the course of several hours. Tracy lift station failed after four days of continuous maximum capacity pumping and the threat of flood continued to loom into August of 2014, necessitating Public Works monitor creek levels. The results of this flood event continue into 2015 with bridge repairs and FEMA reimbursement requests. In 2014 the public work department also saw over 70 frozen water services and the failure of one of the City's 18 wells. ENGINEERING DEPARTMENT 7450 Metro Boulevard • Edina, Minnesota 55439 www.EdinaMN.gov . 952-826-0371. Fax 952-826-0392 In 2014 the Engineering Department lead projects that construct, reconstructed or rehabilitated 15,822 feet (3.00 Miles) of road, 15,729 feet (2.97 Miles) of water main 14,304 feet (2.71 Miles) of sanitary sewer and 1,894 feet (0.36 Miles) of storm sewer. In addition to the many reconstruction projects, the Engineering department's continuous improvement initiatives led to changes in: • Public right of way management, stormwater and erosion control permitting, inspection and enforcement relating to residential redevelopment drainage issues • Correction to errors in pending FEMA floodplain elevations areas • Improvements in neighborhood street reconstruction program resident communications • Use of innovative technology to extend water main life (detailed below) Last year also saw the roll out of a mobile application "Edina To Go." This project was led by Communications and Technology Services Department and upon roll out was linked directly to Public Works service requests in the Cityworks asset management software. Now residents have access to an app to request: Damaged mailbox or sod, fire hydrant inspections, weed issues, street light out, traffic safety, water leaks and more. 2015 Initiatives and Future Opportunities This section will highlight and describe utility issues, and the 2015 departmental work plan initiatives that staff intends to consider addressing each. Neighborhood Street Reconstruction Program I Selection Criteria The trend of aging infrastructure challenges the City to find efficient ways to renew and rehabilitate utility infrastructure. The method of project deliver in this case, matters greatly. The City's neighborhood street reconstruction program continues to provide a cost effective project delivery method that bundles a variety of system improvements. Street reconstruction projects allow the City the opportunity to rehabilitate streets and utilities at the same time for less capital compared to stand-alone projects. While stand-alone utility projects make sense in some cases. In 2014, the City spent a total $2,500,000, $1,500,000, and $1,100,000 in water, sanitary, and storm infrastructure, respectively, with a majority of the work timed to coincide with a street reconstruction. Note that these values were lower than expected due to the delay of the 54' Street and Birchcrest Neighborhood Projects. The ability to rehabilitate multiple systems as part of a single project provides cost savings to the City and reduces impact on residents. This type of integrated project scope decision requires more work up front, and high quality data linking system needs and service and is well supported by the 'asset management approach' described in below. In 2015 Engineering will continue to refine our selection criteria for utility, neighborhood and Municipal State Aid projects, consider alternative pavement management funding sources, and schedule 2019 neighborhood reconstruction projects. Asset Management Approach Water, sanitary, and stormwater public utility services are provided using extensive physical infrastructure and modest programmatic efforts. Each utility is planned, operated, maintained, expanded, replaced, and managed by professional staff in the City's Public Works and Engineering departments. Engineers and system operators use a process called "asset management" to set service levels, assess the present condition of the infrastructure, judge system performance, plan for repair, replacement, or future upgrades, and assess risks. ENGINEERING DEPARTMENT 7450 Metro Boulevard • Edina, Minnesota 55439 www.EdinaMN.gov . 952-826-0371 . Fax 952-826-0392 The tools, methods and processes used to manage aging infrastructure are becoming increasingly data intensive. Engineering and Public Works share geographical information systems (GIS) records, and collaborate on the development of the Cityworks service request, work order and asset management software (AMS). Development and staff training supporting these software tools enable increasingly efficient records management, workflow tracking and process improvement, and trend and system analysis. The rate of adoption for these information systems is currently limited. In 2015 the City will be considering its options for organizing and staffing enterprise GIS solutions. As the City's earliest adopter and most advanced user of these software solutions, Engineering and Public Works will take an active role in planning and implementing GIS/AMS to enable increasingly complex street reconstruction decision making, track reliability trends, and increase service and response by providing annual reporting on outages, repair costs, and performance metrics. Additional information on this topic is available in the 2015 Water, Sanitary and Stormwater Utility Systems Report. In addition to information management system improvements, the technology to assess utility condition continues to develop. In 2015 Engineering will continue to refine its water main selection criteria for replacement and rehabilitation. Planning for sanitary demand growth Growth in service demand in southeast Edina is expected to continue, and our initial review show need for additional trunk sanitary capacity in southeast Edina in the next decade. Capacity in the regional trunk sewer than serves southeast Edina is ample, and while there may be capacity limitation in the local trunk system, remedying these constraints are entirely within our control. The schedule for trunk sewer capacity additions in the Pentagon Park neighborhood is heavily dependent on Met Council action. In 2015 Engineering will work with a consultant to make recommendations to serve this demand growth and funding strategies to pay for the needed infrastructure and lay the groundwork for a sewer plan that will support the upcoming Comprehensive Plan update. Innovative Technology to Extend Water Main Life A testing technique implemented as part of the continuous improvement initiative provided major savings to the City was the use of non-destructive water main testing in the Arden Park D Neighborhood. This data provides a better understanding of the remaining life of those pipes and led to better replacement and repair decisions. This change resulted in estimated savings to our water utility fund of approximately $500,000. We are now using this data collection technique on most of the street reconstruction projects 2 -years in advance to make better decisions about our water infrastructure. This effort will continue water main assessment in 2015 for upcoming neighborhood reconstruction projects. Redevelopment A near doubling of permit applications and residential redevelopment activity between 2009 and 2014, consistent staffing levels, and specific concerns for the impact of construction activities and associated drainage issues on nearby residents and property has led to an evolving community consensus that has raised the expectation of service for permitting redevelopment. Water quantity and erosion and sediment control are specific areas Engineering gets involved though the review of flooding risk, site hydrology, erosion and sediment control precautions. ENGINEERING DEPARTMENT 7450 Metro Boulevard • Edina, Minnesota 55439 www.EdinaMN.gov • 952-826-0371. Fax 952-826-0392 Continuing on the last two years of work, the Engineering Department will continue to engage with Planning, and Building Departments to identify permit review gaps, proactively improve and streamline plan review, permitting and inspections, and assist in site -by -site inspection and enforcement response. In 2015, the Engineering department will promote related drainage policy and flood ordinance development to support redevelopment enforcement and this effort is described below. Flood Risk Assessment / Unified Local and Regional Flood Planning Flooding is assessed and regulated on both a regional and local level. The Federal Emergency Management Agency (FEMA) Flood Plain Maps define regional flooding areas surrounding larger water systems, such as Minnehaha and Nine Mile Creeks. These areas are subject to flooding from a large area, and floodwaters tend to stay high for a significant amount of time when there is a flood. The City regulates these regional flood plains through the Zoning Ordinance, limiting the types and amount of development allowed in the flood plain. Local flooding, however, affects smaller areas. The Comprehensive Water Resources Management Plan (CWRMP) includes a hydrologic model of the City's storm water system. It identifies local flooding areas throughout the city. The CWRMP also gives general guidelines for redevelopment within these areas. Through road reconstruction projects and residential and commercial redevelopment, staff has found gaps in policy for regulating both regional and local flooding areas. There are gaps in the level of protection provided; many buildings are protected from flooding that occurs during a 100 -year storm, while others are only protected to a 50 -year storm or less. There are gaps in redevelopment standards, such as minimum low floor elevations, for both types of floods, but these often conflict with other requirements, such as portions of the zoning ordinance that requires the first floor elevation stay close to the existing elevation. In 2014, the City hired Barr to look at six local flooding areas that require study. The results from this study show that some of these areas can be fixed with upcoming road reconstruction, but some have no solution or potential solutions are prohibitively expensive. While the City is working towards solutions to existing local and regional flooding areas, there is opportunity to prevent new flooding issues or reduce flooding in existing areas through clear policy and redevelopment requirements. It is necessary to have reliable data in order to regulate flooding areas. The CIP includes a 2016 project to update the entire model included in the CWRMP. Model updates will include changes to the storm water system since 2004, updated rainfall data, and flow information. Staff begins preparation for the model update in 2015. FEMA is in the process of revising the Flood Plain Maps for Hennepin County. The City will need to update flood plain ordinance language in order to adopt the new maps. This is an opportunity to examine the regulations and make changes. FEMA has a voluntary program called the Community Rating System (CRS). By completing and documenting activities in four areas, cities can reduce the cost for flood plain insurance for residents and businesses by 10-45%. The flood plain ordinance revision is an opportunity to implement some of these activities. Staff will also look at policy for local flood areas at this time to ensure that requirements are cohesive and complete. Stormwater Project Scope Example A continuous improvement initiative Engineering is implementing in 2015 that will provide a savings to the storm water utility fund related to the sump drain pipe. As part of our street reconstruction projects, sump ENGINEERING DEPARTMENT 7450 Metro Boulevard • Edina, Minnesota 55439 www.EdinaMN.gov . 952-826-0371 • Fax 952-826-0392 drain pipe is installed wherever feasible. The sump drain pipe allows homeowners to connect drain tile and sump pumps. Past practice has been to provide a sump drain service pipe to every home. We have seen a low percentage of homes connecting to that system until they are redeveloped, and in most redevelopment cases, the location of the sump drain service pipe in not in the location they want. Therefore, in 2015 sump service pipes will be provided without a dedicated service connection. In the future property owners will be able to make the connect to that system with the flexibility to connect at any point along their property. This initiative will save our stormwater utility fund approximately $200,000 per year. Engineering will still work with the handful of residents that want to connect immediately as part of the project. Alignment of Watershed District and City Clean Water Goals The Minnesota Pollution Control Agency (MPCA) issued a new storm water permit for cities in 2014. The new permit requires additional storm water education, public involvement, illicit discharge detection and elimination, construction site erosion control, post -construction storm water management, and internal good housekeeping activities. The City's Storm Water Pollution Prevention Plan (SWPPP) guides and documents these activities. There are changes required for ordinances, policies, and procedures for storm water that will be implemented this year. Partnership agreements between the City and the watershed districts, currently under development, will address several of the requirements while increasing city and watershed district efficiency and ability to work together. Some of the activities in the SWPPP also align with the work on redevelopment and flood plain. Private Sanitary Service 1/1 Source control of infiltration and inflow (1/1) waters is an important, but historically neglected strategy to manage peak, storm related, events that can cause surcharge of the sanitary system and backups into low basements. The June 2014 rainfall, and subsequent surcharge notice from the Met Council, reminds us the importance of these long term programmatic efforts to reduce 1/1. Engineering has reviewed three leading metro area communities and their different approaches to public and private 1/1 reduction. Other Future Opportunities Other future initiatives to address the challenges of aging infrastructure include the following: Consideration of sanitary and water service levels definitions and long term needs assessments as part of the upcoming update to the Edina Comprehensive Plan, additional risk based operation and maintenance procedures that rate key individual system components in terms of its likelihood and consequence of failure, additional standardization of system design and components, and consideration of non -infrastructure programmatic source and demand controls such as sanitary inflow and infiltration reduction, user education and assistance to prevent grease or flushing materials that clog sanitary pipes, street sweeping for clean water, and others. Conclusions Water, sanitary and stormwater public utilities provide critical public health, sanitation and public safety services. These services rely on aging infrastructure systems, the operations, maintenance, engineering and design of which support their continual function. Edina's commitment to its utility infrastructure is evident in its mission: "Our mission is to provide effective and valued public services, maintain a sound public infrastructure ... ... in a manner that sustains and improves the uncommonly high quality of life enjoyed by our residents and businesses." This tradition of stewardship pays dividends for generations. G:\PW\CENTRAL SVCS\ENVIRONMENT DIV\Asset Management\State of Utilities\150303 State of Utilities Memo.docx ENGINEERING DEPARTMENT 7450 Metro Boulevard • Edina, Minnesota 55439 www.EdinaMN.gov . 952-826-0371 • Fax 952-826-0392 DATE: March 3, 2015 TO: Mayor and City Council CC: Brian Olson PE, Chad Millner PE., Patrick Wrase PE FROM: Ross Bintner PE - Environmental Engineer RE: 2015 Water, Sanitary and Stormwater Utility Systems Report This memo summarizes domestic water, sanitary sewer, and storm sewer systems, system risk and resilience and system understanding. Background Development that initially drove construction of Edina's infrastructure proceeded from the northeast to the southwest. This phased development is shown in Figure I — Residential Periods of Construction and Figure 2 — Age of Buildings. A portion of northeast Edina was constructed in the 1940s and earlier. The majority of infrastructure in the City of Edina was constructed in the 1950s and 1960s. Minor infill development occurred in the 1970s and 1980s. With the bulk of its infrastructure in the 1950s and 1960s cohorts, the City has begun reconstructing significant portions of its streets and portions of its pipe infrastructure to maintain service reliability as the systems age. Figure 3 — Local Bituminous Street Reconstruction History shows areas of street reconstruction over the past 16 years. Figure 4 — Anticipated Local Bituminous Street Reconstruction shows potential areas of reconstruction over the next five years. Services Delivered The City of Edina operates a public utility providing water, sanitary and stormwater services. These utility services provide: 1) Clean and reliable drinking water to: a. promote public health, and b. waters to suppress fire for public safety. 2) The collection, treatment and disposal of sanitary sewer waste to: a. prevent disease, and b. promote public health. 3) Management of flood waters and floodplain to: a. promote public safety, and b. protect property. 4) Management of stormwater runoff to: a. prevent pollution, b. promote the public health, and c. improve the health of local water bodies and the environmental services they provide. ENGINEERING DEPARTMENT 7450 Metro Boulevard • Edina, Minnesota 55439 www.EdinaMN.gov . 952-826-0371. Fax 952-826-0392 Decision-making for Maintenance and Reconstruction The water, sanitary, and stormwater public utility services are provided using extensive physical infrastructure and modest programmatic efforts. Each utility is planned, operated, maintained, expanded, replaced, and managed by professional staff in the City's Public Works and Engineering departments. Engineers and system operators use a process called "asset management" to set service levels, assess the present condition of the infrastructure, judge system performance, plan for repair, replacement, or future upgrades, and assess risks. The tools used to manage aging infrastructure are becoming increasingly data intensive, but lead to better decisions. Also increasing management complexities are the better scientific understanding of both the chemical, physical and biological processes acting on the systems and the infrastructure's interaction with the natural systems on which each utility service depend. Evolving methods of assessing system condition such as non-destructive water main sounding, and closed circuit television allow nuanced replacement decisions. Changing methods of inspection such as nondestructive water main sounding, and construction, including trenchless installation and robotic pipe rehabilitation technology also have changed project scope choices, and continue to lower overall cost of repair. Understanding of Infrastructure The following is a brief description of each of the utilities in the City of Edina including: 1) Description of service: An overview of the service(s) provided, system extents and critical design considerations. 2) Infrastructure summary: A description of major components of the system, scale of system and current estimated replacement value (not including potential restoration costs such as pavement or sod.) 3) System understanding: List of the most recent plans, review of the key design variables, reliability and risks. 4) Function and condition assessment: Review of methods to assess system and overview of issues with age and existing materials. Water 1) Water ptoduction and distribution infrastructure is built to provide uninterrupted service of clean drinking water citywide, and is made available in abundance for firefighting. Water is supplied from groundwater aquifers through wells spread throughout the community and distributed via a network of pipe. Some wells are connected to water filtration plants and are used to provide water in normal use periods. The remaining wells are unfiltered and rotate into service during summer peak use periods. A small portion of the City is served by Eden Prairie, Bloomington, Saint Louis Park or Minneapolis water supply. 2) The domestic water system is made up of two parts. The first is a water distribution system that includes: 220 miles of pressure water main ranging from 4-16" in diameter, nearly 5000 main valves, 2000 hydrants, and 13800 service connections, valves and meters and equal numbers of private service pipes. The second is a water production, storage and treatment system that includes: 18 wells, 4 treatment plants, 4 water towers, and I reservoir. The estimated 2015 total replacement value of this infrastructure is over $160 million. ENGINEERING DEPARTMENT 7450 Metro Boulevard • Edina, Minnesota 55439 www.EdinaMN.gov • 952-826-0371 • Fax 952-826-0392 3) The current system understanding is based on the 2002 Water Distribution System Analysis by SEH and the 2013 Wellhead Protection Plan by Source Water Solutions. The City also has a current InfoWater model that describes the distribution system, and regional agencies maintain a variety of regional groundwater models used to understand and assess groundwater risk and supply. Modeling that enhanced the system understanding include a 2013 Water System Demand and Capacity Analysis for Water Treatment Plan 5 (WTPS). The water distribution system is sized based on geometric constraints, system wide supply and demand, design pressure, and fire flow capacity. Supply systems include pumps with reliable power backup, to keep the distribution system under constant pressure to meet demand and keep contaminants out. The production system is designed to meet peak day and peak week demands, assuming the largest well in the system is out of service. 4) The current method of condition assessment is through maintenance records, continuity comparison between pumped and metered flow, and visual inspection of the main during water main repair work. The water system is remotely controlled by a data collection and control (SCADA) system, and this system also provides insight into system function. System age affects service reliability as spot repairs are made due to water main and service breaks. Figure 5 — Watermain and Service Breaks shows recent repair density on water main currently in service across the city. Note sections in north east Edina with few breaks or service breaks were recently fully replaced. Figure 6 — Water Pipe Material Distribution shows material type distribution citywide. Some areas of northeast Edina have had full pipe replacement or pipe lining with new high-density polyethylene (HDPE). Additional looped connection pipes are considered to raise service levels in areas with low pressure or stagnant water complaints. Sanitary 1) Sanitary collection system infrastructure is built to transmit peak flows without surcharge and reduce risk of human exposure. Wastewater is collected and routed via private service connections to lateral and trunk sanitary pipes and then on to the regionally operated Met Council system. There it is conveyed to either St. Paul Metro or Eagan Seneca treatment plants for treatment and disposal of waste. The system functions via gravity flow, with intermittent pump lift stations and sanitary force main when needed. 2) The sanitary system is made up of three parts. The first includes privately owned service pipes. The second is a City -owned collection system that includes: 194.2 miles of gravity main ranging from 4-33" in diameter, over 5000 maintenance access manholes, 4.5 miles of force main, and 23 lift stations. The third is a regional trunk conveyance and treatment system owned and operated by the Met Council, to which the City pays fees based on use. The estimated 2015 total replacement value of the City portion of infrastructure is just under $70 million. System costs for the Met Council systems are prorated metro area wide by metered flow volume. 3) The current system understanding is based on a 2006 XP-SWMM model by Barr and a 1997 Sanitary System Evaluation by TKDA. Inflow and Infiltration is document sin reports by CH2M Hill, 1992 and by Donohue, 1983. The collection system was designed based on expected total and daily peak flow, estimated based on land use, density, average population per household, average per capita water use, and an allowance for inflow and infiltration during storm events at the time of development. The system is metered continuously at three locations by the MCES, and modeling and calibrated flow metering are periodically conducted to predict and track flow trend, most recently in 2006 and 2012. Reducing inflow of floodwaters ENGINEERING DEPARTMENT 7450 Metro Boulevard • Edina, Minnesota 55439 www.EdinaMN.gov . 952-826-0371. Fax 952-826-0392 through manholes, basement foundations, parking garages, and other structure flooding can increase reliability and reduce costs. Reducing infiltration of stormwater though pipe and service lining can reduce treatment costs. 4) The current method of condition assessment is through closed circuit televising of lines, maintenance records, and visual inspection of manholes. Sanitary lift stations are remotely controlled by a supervisory control and data acquisition (SCADA) system, and this system also provides insight into system function. Lining of clay pipe (VCP) is considered a high priority to increase reliability and reduce infiltration. Figure 7 — Sanitary Pipe Material Distribution shows the majority of the system as VCP, with three of the four major trunk lines primarily made of reinforced concrete (RCP). Locations of cast in place cast in place pipe (CIPP) liner, and PVC and HDPE show the extent of pipe rehabilitation work. Stormwater 1) Storm sewer conveyance system infrastructure is built to carry the water from a storm with a 10% chance of occurring in a given year for neighborhood and lateral systems, and water from a storm with a I% chance of occurring in a given year for trunk and regional systems. Floodplain is managed to minimize damage and maintain flood storage and conveyance capacity. Stormwater treatment infrastructure is built to meet regulation defined pollutant removal targets, and is complemented by programmatic pollution prevention techniques and system maintenance such as street sweeping, stormwater education, illicit discharge enforcement and sediment trap manhole cleaning. 2) The stormwater system includes over 127 miles of gravity main ranging from 12-84" in diameter, 6800 manholes, 900 outlets, 38 miles of sump drain, I I stormwater lift stations, one-half mile of stormwater force main, 150 ponds and wetlands, and numerous sediment trap structures. The estimated 2015 total replacement value of this infrastructure is over $65 million. 3) The current system understanding is based on the 2011 Comprehensive Water Resources Management Plan by Barr. The collection system is designed to provide drainage and manage flood risk. Recent upward revisions to storm frequency probability (NOAA Atlas 14) mean portions of the system previously meeting design standards are now considered under sized, and flood storage areas now have higher peak flood elevations. Treatment systems are designed to meet pollutant removal standards set by the State and Watershed Districts. Clean water service demand due to water body specific Total Maximum Daily Load (TMDL) regulation is increasing. There is no reliable estimate for future liability. 4) The current method of condition assessment is through visual inspection of storm manholes and outlets and some closed circuit televising of lines where needed. System function is checked with a calibrated computer model and though visual inspection after large storm events. Pollution removal is estimated with an un -calibrated computer model. Comprehensive Plan and Areas with Local Demand Growth Areas of the City are subject to future redevelopment. This redevelopment is expected to result in significant demand growth primarily around Southeast Edina including Pentagon Park. Local commercial nodes such as 50' and France, Grandview, Cahill and Valleyview/Wooddale also expect modest demand growth. In anticipation of this redevelopment, staff completed various infrastructure system studies to verify capacity or ENGINEERING DEPARTMENT 7450 Metro Boulevard • Edina, Minnesota 55439 www.EdinaMN.gov . 952-826-0371. Fax 952-826-0392 identify system needs to accommodate growth. In addition to those system studies referenced above, the conclusions in this memo and project recommendations are informed by the following studies. Water I.

In acknowledgement of the continued pressure to redevelop to mixed uses around existing commercial and office districts and the increase in development density envisioned in Chapter 4, Chapter 8 describes broad trends in system capacity and the ability of the existing infrastructure to meet future service demand. Two development scenarios were reviewed for sanitary and water capacity during the development of the plan; Scenario I included Met Council estimates for growth in population and employment and Scenario 2 describes an ultimate possible development density. The Met Council estimate in Scenario I assumed a change from 48,500 residents and 52,100 jobs in 2010 to 50,000 residents and 57,400 jobs in 2030. The ultimate development density assumed in Scenario 2 was 70,149 residents and 70,000 jobs. Both scenarios assume the bulk of growth will occur in the southeast quadrant of the City in existing commercial areas. The new 2030 population and job projections due out this year appear to be falling on the mid to low side of the range of these two scenarios. The following is a more detailed review of each utility, with a focus on growing areas in southeast Edina: Water Comprehensive Plan Chapter 8 describes trends and challenges to the public water supply. Generally, the City has a resilient water system that can produce clean, safe and plentiful water for public use. The increasing occurrence of groundwater quality issues and contamination (vinyl chloride and radium) has led to increased treatment needs. Providing water for the peak demand is also a concern. The demand for water increases in the evenings due to in-home use and in the summer due to irrigation systems. The average daily demand in Edina is between 7 and 8 million gallons per day (mgd). The peak demand is between 14.5 and 22 mgd, which is about three times higher than the average daily demand. This is known as the peaking factor, and Edina (with a peaking factor of 3.0) is in the high end of the range that is typical for similar suburban communities. ENGINEERING DEPARTMENT 7450 Metro Boulevard • Edina, Minnesota 55439 www EdinaMN.gov . 952-826-0371. Fax 952-826-0392 Under Scenario 1, two additional wells and no additional water storage would be needed assuming no decrease in the peaking factor, or one additional well with a reduction in the peaking factor resulting from conservation efforts. Under Scenario 2, even with aggressive conservation efforts and a corresponding reduction in the peaking factor from 3.0 to 2.75, an additional 7 wells or equivalent supplementary sources will be needed. No major upgrades to the distribution system are required for either scenario assuming aquifer capacity is available and water supply is sources by local wells. Upgrades to the distribution system may be required under Scenario 2 if water purchase agreements with nearby communities were pursued. Additional filtration capacity is desirable under both scenarios. Sanitary System flow in the water and sanitary systems are closely linked. In general, declining trends in system flow were noted in the sanitary sewer between 1980 and 2000, with a flat trend between 2000 and 2010. Reasons for decreased demand include changing demographics (fewer people per household) and increasing retrofit of buildings to include efficient modern fixtures and appliances. Reasons for increasing demand on system use include redevelopment and leaky aging pipes. The Met Council expects to see continued pressure for redevelopment along the 494 corridor, and has improved regional trunk sewer conveyance capacity as a result. This additional capacity is extended to the City boundary at Xerxes and 75`' and can be extended into the southeast quadrant of the City with additional trunk infrastructure investment. Both the 2006 XP-SWMM analysis and 2008 Comprehensive Plan concluded that Scenario I could be accommodated without major trunk line upgrades but Scenario 2 would require major system upgrades, dependent on redevelopment density and pattern. In 2013, the Engineering Department directed Barr Engineering to review the sanitary sewer model for flow capacity constraints in southeast Edina. In general Southeast Edina is well served in the near term with some excess capacity available for growth. The review shows most lateral lines have excess capacity, and trunk lines are running nearer to design capacity. The review also shows a trunk line serving western Edina and the Hwy 100 / Cahill industrial area running at capacity. The portion of southeast Edina that serves the hospital and flows to MCES meter RF -490 (65th/Xerxes trunk) has limited remaining capacity. Stormwater Storm system flows are linked to hydrologic, geologic and geometric attributes such as the connectivity in a drainage area, the percent of a site that is impervious, condition of the soil, and vegetation. In general, the service demands for clean water and flood protection are growing based on increased understanding of natural systems and regulation by state and local watersheds to remediate and protect local waters. While Nine Mile Creek capacity in southeast Edina show some flooding risk, infrastructure used to provide local flood protections is generally robust, and soil conditions in much of the area are favorable to reducing runoff. There is an increasing pressure on flow due to redevelopment at higher densities, but local controls require much of the flow and water quality treatments to happen on-site for large lot and commercial development. This trend will lead to less utilization of city infrastructure for small storm events, and a continued reliance for large storm events. Residential redevelopment runs counter to this trend because treatment and control is not required for lots less than one acre in size. ENGINEERING DEPARTMENT 7450 Metro Boulevard • Edina, Minnesota 55439 www.EdinaMN.gov . 952-826-0371. Fax 952-826-0392 Additional demand analysis was conducted for the Grandview area, and aside from minor sanitary lift station and looped water recommendations, the area is well served to meet future demand. Demand analysis for the Gateway/Pentagon park area was studied in detail in the June 2013 Update to the September 26, 2007 Alternative Urban Areawide Review (AUAR) by WSB Engineering. Demand growth in this area will require the improvement of flow capacity at a Met Council lift station, and additional local sanitary capacity in Edina and Bloomington. Conclusions Water, sanitary and stormwater public utilities provide critical public health, sanitation and public safety services. These services rely on aging infrastructure systems, the operations, maintenance, engineering and design of which support their continual function. The City is well served by its aging utility infrastructure and the level of investment is favorable to support localized demand growth and its continued function.
