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 1 1000 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.

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 / 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`h 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

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 /I. 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.

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.

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 production 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 (WTP5). 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.
Sanitaiy
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

The Edina Comprehensive Plan was updated in 2008. 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.

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`h 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.

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.
