STAFF REPORT
DATE: 08/10/2022
DISCUSSION
TO: City Council
FROM: Molly Just, Planning Director
Ben Hetzel, City Planner
AGENDA ITEM: Stormwater Reuse for Irrigation
BACKGROUND:
City Council directed the Planning Department to research the possibility of stormwater reuse for
irrigation purposes and report back with findings at the August 10, 2022 City Council Workshop.
Stormwater reuse for irrigation could benefit the City by reducing overall demand for potable
water in Lake Elmo.
ISSUE BEFORE CITY COUNCIL:
Should the City adopt code requirements for stormwater reuse for irrigation?
PROPOSAL DETAILS/ANALYSIS:
Staff researched surrounding communities to see how stormwater reuse for irrigation is
incorporated. Staff found that as of yet no metro communities have adopted code requirements
for stormwater reuse for irrigation purposes. However, there are a couple of metro communities
that are engaging in stormwater reuse for irrigation purposes. Examples of communities that
incorporate stormwater reuse for irrigation are the cities of Hugo and Waconia.
Waconia
The City of Waconia has a stormwater reuse code (Chapter 415). The code does not have a
requirement to construct these systems, but rather focuses on the standards and requirements
residents must abide by shall they decide to voluntarily connect to the City’s system.
Hugo
In order to implement stormwater reuse, the City of Hugo partnered with the Rice Creek
Watershed District and adopted a Stormwater Capital Improvement Plan (CIP). This approach
identified approximately 20 potential projects that could effectively reduce the City’s
groundwater dependence. Three examples are provided in your packet.
The City of Hugo does not have a stormwater reuse for irrigation code. Hugo adopted
Comprehensive Plan policy language to encourage stormwater reuse practices. Many new
developments have incorporated stormwater reuse for irrigation. The City does not provide
developers incentives for implementing stormwater reuse systems. Hugo planned for
stormwater reuse city-wide and regionally allowing developers to meet some stormwater
requirements offsite. Example would be meeting water quality standards offsite and only having
to meet rate control onsite. This is a benefit to developers, as there is a possibility of a reduction
in stormwater construction costs. Hugo has a combination of both City and HOA owned
2
systems. City owned systems and HOA owned system each provide residents with a lower
irrigation cost than regular city water rates.
CATEGORIES TO CONSIDER
Stormwater reuse for irrigation in newly platted development residential development with
Homeowner Associations. The City does not want to manage or own the development-based
part of the irrigation system and so needs the responsible party (HOA) to make it work.
POTENTIAL OPTIONS:
1. Add a requirement in City Code for ALL such newly platted developments to
incorporate stormwater reuse for irrigation.
2. Amend the 2040 Comprehensive Plan to add policy language encouraging
stormwater reuse for irrigation.
Incorporate education opportunities to educate businesses and homeowners on appropriate
techniques for stormwater reuse.
POTENTIAL OPTIONS
1. Use of City’s website
2. Water bill mailings and other recurring mailings
3. The Fresh
4. Facebook
5. The Source
Provide incentives for incorporating stormwater reuse for irrigation.
POTENTIAL OPTIONS
Add an amenity category for advanced stormwater reuse in Planned Unit Development
(PUD) Code. This could be for certain types of projects only or a way to reduce use of
potable water for irrigation in commercial projects that wouldn’t be required to
incorporate it. Council direction is requested.
VALLEY BRANCH WATERSHED COMMENTS
The Valley Branch Watershed District relies on the Minnesota Stormwater Manual for guidance
in stormwater reuse projects. Developers still need to prove that rate and volume control is met
at all points where water leaves a site.
EXAMPLES OF STORMWATER REUSE SYSTEMS
Hugo
Most of these examples were provided in the City of Hugo’s Capital Improvement Plan for
Stormwater Projects. These projects have reduced groundwater demand by approximately 80
million gallons per year.
Water’s Edge Water Reuse - The City working with Homeowners Association to pump water
from selected stormwater ponds within Waters Edge development for irrigation purposes in place
of city water.
3
Beaver Pond Park – Pumping stormwater from a nearby pond to irrigate the park. The park used
to use thousands of gallons on potable water.
Oneka Ridge Golf Course- Stormwater pond created along the 18th tee and now collects runoff
from 915 acres of land. The water is pumped and used for golf course irrigation. Excess water
beyond what is needed is sent to an infiltration system.
Carver County
Carver County Club West Development – The developer worked with Carver County Watershed
Management Organization to harvest and utilize stormwater draining from the new development
for irrigation of common areas of the 60-unit development.

Guiding Principles
The goals and policies outlined in the WRMP are grouped by their relationship to the key issues listed below:
• Section 5.2 – Volume Management
• Section 5.3 – Water Quality
• Section 5.4 – Runoff Management and Flood Control
• Section 5.5 – Wetlands
• Section 5.6 – Erosion and Sediment Control
• Section 5.7 – Groundwater
• Section 5.8 – Recreation, Habitat and Shoreland Management
• Section 5.9 – Education and Public Involvement
• Section 5.10 – Public Ditch System
A general goal of the City is to cooperate, collaborate, and partner with other entities, such as the Watershed Districts and the MPCA. Cooperation, collaboration, and partnering results in projects that are less likely to conflict with the goals of the affected entities, are better able to meet long-term goals, and are generally more cost-effective.
Strategies
Hugo pursues a reduce, reuse, and replenish philosophy through its stormwater management policies. Hugo’s policies are designed to:
• Reduce stormwater runoff to prevent the damage that occurs to lakes, streams, and wetlands from urbanization.
• Reduce reliance on groundwater by encouraging projects that reuse stormwater for irrigation.
• Favor a regional approach to preserve and replenish underground drinking water supplies. This regional approach substitutes surface water for groundwater where possible and seeks to replenish groundwater supplies by active regional management of existing appropriations and by consideration of an aquifer recharge and storage program.
CITY OF HUGO WATER RESOURCES MANAGEMENT PLAN
SECTION 5 Page 1
5. GOALS AND POLICIES
5.1. General
The goals and policies in the City of Hugo’s Water Resource Management Plan are consistent
with the goals of the Rice Creek Watershed District (RCWD), Brown’s Creek Watershed District
(BCWD), Carnelian-Marine-St. Croix Watershed District (CMSCWD), and Washington County
Groundwater Plan, while meeting the more specific and changing needs of the City. The goals of
this plan were established in accordance with the guidelines contained in Minnesota Statutes
103B and Minnesota Rules 8410. Furthermore, each goal has several corresponding policies.
These goals and policies provide for future development and redevelopment while minimizing
surface water problems and enhancing the environment. These goals and policies are subject to
conformance with current Watershed District policies and standards as well as Washington
County groundwater management policies.
The City currently has permitting authority over RCWD Rules C, D, E, and F for areas of the City
within the RCWD boundaries. The City adopts and enforces the most recent RCWD Rules for
which the City has permitting authority as listed previously. The City does not have permitting
authority in BCWD or CMSCWD as such, any permit review or approval required within these
jurisdictions must be applied to and approved by the respective watershed district. In accordance
with Minnesota Statutes section 103B.211, subd. 1(a)(3)(iii), the City of Hugo defers exercise of
regulatory authority over the activities subject to the BCWD’s rules and CMSCWD’s rules to each
watershed district. Additional goals and policies of the City are contained throughout this section.
A general goal of the City is to cooperate, collaborate, and partner with other entities, such as the
watershed districts and the MPCA as much as possible as the City implements this plan.
Cooperation, collaboration, and partnering results in projects that are less likely to conflict with the
goals of the affected entities, are better able to meet long-term goals, and are generally more
cost-effective.
In addition to the goals and policies outlined below, the City will annually review and update its
Storm Water Pollution Prevention Plan (SWPPP) to effectively manage its stormwater system
and be in conformance with the NPDES MS4 Program. The following are components of the
SWPPP:
Public information and education plan relating to water resources and stormwater
An inspection and maintenance schedule
City housekeeping practices (e.g., street sweeping priorities)
BMPs used by the City to control and/or reduce pollutants
Methods used to control and manage post-construction stormwater
Illicit Discharge Detection and Elimination
Hugo implements a reduce, reuse, and replenish philosophy through its stormwater
management policies. Hugo’s policies reduce stormwater runoff to prevent the damage that
occurs to lakes, streams, and wetlands from urbanization. Hugo’s policies reduce reliance on
groundwater by encouraging projects that reuse stormwater for irrigation. Hugo’s policies favor
a regional approach to preserve and replenish underground drinking water supplies. This
regional approach substitutes surface water for groundwater where possible and seeks to
replenish groundwater supplies by active regional management of existing appropriations and
by consideration of an aquifer recharge and storage program. The City will work with the
appropriate watershed district when developing regional programs and obtain necessary
approvals by those districts prior to implementation.
5.2. Volume Management
CITY OF HUGO WATER RESOURCES MANAGEMENT PLAN
SECTION 5 Page 2
5.2.1. Goal
Hugo will reduce its annual stormwater discharge of runoff volume by infiltrating and
reusing stormwater runoff.
5.2.2. Policies
1. The City of Hugo has adopted a “Reduce, Reuse, Replenish” strategy for the usage
of water. This strategy will reduce the impact on aquifer draw down and allow for
increased aquifer recharge through strategic direct injection infiltration and
stormwater based irrigation practices.
2. The City of Hugo has adopted Atlas 14 rainfall precipitation data and will incorporate
this data into future analyses.
3. Any development or redevelopment within the City of Hugo will give first preference
to infiltration and stormwater reuse as a means to maintain existing runoff volume in
accordance with RCWD Rule C.
4. Reuse projects should function to reduce or eliminate the use of City potable water
for irrigation.
5. Development and redevelopment projects shall reestablish turf according to Hugo’s
turf establishment design guidance: providing sufficient topsoil and organic matter to
sustain turf without excessive irrigation (whether using potable water, reclaimed
water).
6. As allowed by RCWD Rule C.5(f), for properties within the RCWD boundary, the City
of Hugo will develop Comprehensive Stormwater Management Plans (CSMPs) to
manage stormwater at a regional scale within Resource Areas of Concern. These
CSMPs must be approved by RCWD’s Board of Managers prior to City
implementation. The focus of these CSMPs will help to quantify a system of regional
volume reduction projects, mostly stormwater reuse for irrigation, to generate volume
reduction credits on select city roadway and redevelopment projects. Hugo will use
these credits on land development or linear projects where physical constraints do
not allow for cost efficient BMP implementation to address volume reduction. Rate
control requirements will still need to be met for any projects within these CSMP
areas.
7. The City will work with the BCWD and CMSCWD on permitting and stormwater
management as required for possible future development in areas of the City under
their jurisdictions.
8. Development that results in the creation of impervious surfaces must explicitly
address use of BMPs to first limit the loss of pervious area; and second, to:
a. Infiltrate runoff which does occur from impervious areas to the extent feasible
considering site-specific conditions, and/or
b. Reuse runoff for irrigation and other appropriate uses.

CHAPTER 415
STORM WATER REUSE
415.01 Findings and Purposes.
The City of Waconia has an extensive storm water drainage system that includes
storm pipe, holding ponds, drainage ways, infiltration basins and creeks to serve the
needs of the community. The City Council finds that water conservation is a
sustainable strategy that allows for population and economic growth while meeting
the increased demands for water. Storm water reuse supports conservation and
sustainability by reducing impacts on potable water used for irrigation and by
supporting efforts for meeting increasingly stringent storm water requirements. As
competition for water increases and supply becomes more uncertain, implementing
conservation measures will help ensure the City’s economic viability in the decades to
come while preserving its environment.
Based upon the above findings, the City desires to install and operate storm water
reuse systems where it is feasible to do so. Nearby property owners will be allowed
to voluntarily connect to these systems to both drain storm water to designated
ponds and to reuse collected storm water for irrigation.
To help defray the cost of establishing, constructing, repairing, replacing, maintaining,
and improving storm water reuse systems within the City, the City Council finds it is
appropriate to establish connection and consumption charges. The City Council
further finds it is appropriate to levy such charges against the property owners using
such systems.
415.02 Authority.
Connection and reoccurring charges shall be levied and assessed against benefiting
properties pursuant to Minn. Stat. Sec. 444.075, Subd. 3, and pursuant to agreements
with property owners voluntarily using storm water reuse systems. Further, the City
Council finds that, although Minn. Stat. Sec. 444.075, Subd. 3b prohibits setting storm
water charges based upon the volume of water used, this prohibition should be
interpreted to only prohibit charging storm water rates based upon the volume of
potable water supplied to a property through the City’s waterworks system. As such,
this prohibition does not prohibit charging property owners for recycled water based
on volume of recycled water used.
415.03 Definitions.
The following terms, as used in this Chapter, shall have the meanings stated in this
section:
“Chapter 415” means this Chapter 415 of the Waconia City Code, as amended.
“Delivery point” means the primary irrigation box for an owner’s irrigation system.
“Drainage and reuse agreement” means a written agreement between the City and
2
an owner that controls, subject to this Chapter 415, the owner’s use of the system
and grants appropriate easements to facilitate such use.
“Irrigation season” means, regarding each calendar year, the period starting on the
day the City first provides reuse water to the delivery point for use on an owner’s
parcel and ending on the day that the City terminates the delivery of reuse water to
the delivery point. Subject to weather conditions, each irrigation season will generally
start in early April and end in late October.
“Owner” means the owner of fee simple title to a parcel, whether by sale, assignment,
inheritance, operation of law, trustee’s sale, foreclosure, or otherwise, but not
including the holder of any lien or encumbrance on such parcel unless such holder
becomes a fee simple owner thereof.
“Owner’s irrigation improvements” means the facilities and apparatus installed,
maintained and operated on an owner’s parcel to disperse reuse water on such parcel
for landscape irrigation uses.
“Parcel” means a parcel of real property.
“Public Services Director” means the person acting as the public services director for
the City, however titled, or such person’s designee.
“Public Services Department” means the department of the City overseeing
waterworks and storm water facilities, however designated.
“Reuse water” means moderately treated storm water. If at any time the City does
not have enough moderately treated storm water to meet the City’s obligations, then
the City may substitute other water of at least equal quality (e.g., potable water) in
lieu of moderately treated storm water and all references to reuse water shall be
deemed to include the substituted water.
“System” means the pressurized pumps, pumping systems, distribution systems, and
water treatment units maintained and operated by the City for the purpose of
delivering reuse water from a storm water retention pond to parcels of real property
connected to the system for landscape irrigation uses, as the same may be modified,
reconstructed, replaced or improved from time to time.
415.04 Systems.
Subd. 1 Establishment of Systems. The City may, from time to time, establish systems and
determine the parcels eligible to connect to such systems. The City may add a system
by amending this ordinance to list the system and the parcels eligible to connect to
such system in Subd. 6 below.
Subd. 2 Public Utility. Each system shall be owned, operated and maintained by the City and
operated as a public utility pursuant to Minnesota Statutes Section 444.075 et. seq.
and this Chapter 415. Each system shall be under the administrative oversight of the
Public Services Director. All revenues shall be derived subject to the provisions of
Minnesota Statutes, this Chapter 415 and the agreements between the City and each
3
owner. All systems will be designed and monitored to meet filtration development
requirements as established by agreement between the City and the Carver County
Water Management Organization.
Subd. 3 Availability of Systems. Each system shall be generally available during each irrigation
season. The City reserves the right to determine when a system is available and when
weather dictates the system should be connected and disconnected for the irrigation
season. The City shall provide written notice to all owners prior to system start-up and
shut-down each year. The City Council may, by resolution, regulate, restrict, or limit
the use of reuse water during water shortage periods and shall have the power to
enact any necessary regulations, as circumstances may require, to protect the City’s
water supply.
Subd. 4 Minimum and Maximum Reuse Water Volumes. Each owner connecting a parcel to a
system shall be informed, as part of the application process described in Section
416.06 below, of the minimum and maximum reuse water volume amounts applicable
to the parcel. During each day of the irrigation season, the parcel will be required to
consume not less than the minimum volume, subject to abatement as described in
the drainage and reuse agreement for the parcel. Such volume amounts shall be
calculated based upon the size of the parcel by the Public Services Director and
memorialized in the drainage and reuse agreement for the parcel.
Subd. 5 Owner’s Irrigation Improvements. The City will deliver reuse water to a single delivery
point on each parcel connected to the system. Owner’s irrigation improvements shall
be installed at owner’s expense and shall have the capacity to meter and disburse not
less than the maximum volume of reuse water assigned to the owner’s parcel. Each
meter shall be approved by the Public Services Director before it is installed. Frost
protection of Owner’s irrigation improvements must be coordinated with the Public
Services Director annually each season prior to winter.
Subd. 6 List of Approved Systems.
A. 10th Street Regional Pond System. The 10th Street Regional Pond System has a
pond located on real property legally described as Outlot B, Sudheimer
Homestead Addition, Carver County, Minnesota. In addition, there is an
associated pump house located on real property legally described as Outlot B,
Sudheimer Retail Addition, Carver County, Minnesota. Owners of the following
parcels may voluntarily connect to this system:

The parcels listed above and their owners shall not acquire any rights
regarding the 10th Street Regional Pond System until a drainage and reuse
agreement is fully executed by the City and the parcel owner. As such, the City
may amend this ordinance to remove any parcel from the list of eligible parcels
if such an agreement does not exist. Further, the City may amend this
ordinance to add any parcel to the eligible list of parcels notwithstanding the
existence of drainage and reuse agreements with other parcel owners. If a
parcel listed above is subdivided, the provisions of any drainage and reuse
agreement for the parcel shall control.
Subd. 7 Conditions and Prohibitions Regarding Use of Systems.
A. No owner or other person shall waste or allow any reuse water to be wasted
by improperly maintained facilities (i.e., valves, leaky joints or pipes).
Additionally, reuse water shall not be wasted by allowing reuse water to run
continuously from faucets, broken pipes or sprinkler heads or other apparatus,
or to use the reuse water in such a manner as to cause it to overflow into the
neighboring properties, streets, or sidewalks.
B. No owner or other person shall, after a parcel has been shut off for non-
payment of charges or for violation of City Code, turn on or allow reuse water
to be turned on or used without authorization from the Public Services
Director.
C. No owner or other person shall destroy, deface, injure, or interfere with the
operation of any part of the system.

source of reuse water utilized as part of the system) any matter, substance,
chemical, or compound without express authorization from the Public Services
Director.
5
E. No owner or other person shall connect any part of the system to any part of
any drinking water (potable) system, creating a cross-connection whereby
reuse water could be introduced into any system that provides potable
drinking water.
F. No owner or other person shall use reuse water from the system for flood
irrigating any parcel unless the Public Services Director has granted prior
authorization in writing. Except for incidental watering of shrubs, flowers, and
other limited use applications, reuse water from the system used for
landscape irrigation must be applied through either a sprinkler or drip
irrigation system, including sprinklers attached to garden hoses.
G. No owner or other person shall permit any person to use or obtain reuse water
intended for one parcel for another parcel.
H. No owner or other person shall terminate a connection to a system without
the Public Services Director’s consent.
I. No owner or other person, except under the direction of the Public Services
Director, shall be allowed to dig into the street, sidewalk, or other public
