PRESENTATION
Rick Carter Architect with LHB, on behalf of the Urban Land Institute Regional Council of
Mayors gave a presentation about the Regional Indicator Initiative project. This project was an
inventory of energy, potable water, travel, waste, costs, and greenhouse gas emissions for twenty
Minnesota Cities from 2008 to 2011, which did include the City of Eagan. The Initiative supports
planning for sustainability by defining a baseline, tracking a business as usual trajectory,
establishing targets, and measuring outcomes of sustainable strategies at a city wide scale. Trends
for energy that occurred, in most cases, were energy use went down in 2009-2010 and back up in
2011 due to many different factors. Some interesting data trends discovered commercial/industrial
energy use averaged 60% and residential energy use averaged 40%. Trends for water were not
significant except that people were surprised about how much water is used. Residential water use
averaged 58%, which was higher that the commercial/industrial water use average of 42%. There
was not a significant change with travel. Total greenhouse gas emissions mimic the energy use
levels. Rick briefly discussed the correlation with the Greenstep Cities program.
Rick stated that all the information contained in this report will be available on a website in a
couple of weeks. After further discussion by Commission Members the presentation concluded with
a request from the Commission to be provided a copy of the PowerPoint presentation for their
review.

COMMITTEE REPORTS & DISCUSSION
Low Maintenance Landscaping (Amir, Mike, Jon) – Member Wisniewski gave an overview of
the low maintenance landscaping proposal in order to reduce the need for irrigation on residential
properties, encourage sustainable landscaping, and make this process easy for residents. The
proposal was sent to the City Attorney’s office for review and came back to the Commission with
notes and recommendations. Member Wisniewski stated these recommendations go against the
original intent of this proposal. Director Johnson gave a brief overview on the City Attorneys
perspective when reviewing this ordinance change and the struggle to interpret the model ordinance
format which was not the same format as regular ordinances for the City of Eagan. Jon Hohenstein,
Director of Community Development, addressed the Commission to recommend a meeting with the
City Attorney, Subcommittee, and City Staff to discuss recommendations for this ordinance and to
put this ordinance in a language that may be able meet the needs of all parties involved. If not able
to meet the needs of all parties, the Subcommittee will create a clear list of pending issues between
the Commission, City Attorney, and City Staff to provide to the City Council at the June meeting.
After further discussion by the Commission and City Staff the Commission agreed to direct the
Subcommittee to have a meeting with the City Attorney and City Staff within the next 30 days. If
changes are needed the Commission will hold a special meeting and a work session before the June
meeting with the City Council. Member Bintner made a motion that the Energy and Environment
Commission expresses support for Section 10.21 as it is drafted on pages 90 thru 94 of the packet,
Member Wisniewski seconded, with all member present voting against the motion 0 Aye and 5 Nye.
Solar (Amir, Mike, Jon) – Member Nadav gave a brief overview of this work plan item. A letter
was received letter from the Minnesota Solar Project listing potential barriers with the City’s
ordinances regarding solar energy development. The Community Development Department has
received this letter and it is currently being reviewed. Member Nadav requested the Commission
review the recommendations from the Planning Commission before City Council for approval.
Director Hohenstein spoke briefly and recommended the Commission Subcommittee meet with City
Staff to work through the details of this ordinance. Member Bintner requested a motion to
recommend that City Council direct City Staff to create an ordinance amendment pursuant to the
options in the letter from the Minnesota Solar Challenge, forward the proposed changes to the City
Attorney for review and copy all recommendations to the Energy and Environment Commission for
review before going to the City Council, Member Wisniewski seconded, with all member present
voting in favor of the motion.
Water Conservation (Amir, Ross) – Member Bintner gave an overview of the water
conservation report and proposal. The water conservation subcommittee proposed the Energy and
Environment Advisory Commission recommend the following items to City Council for consideration:
Adopt a city-wide goal of reducing per capita daily water use by 10% by 2020 and 15% by
2025 below a baseline of the average per capita daily water use from 2005 - 2010.
Register the City in the free and voluntary WaterSense partnership program and appoint
water utility staff to administer program implementation.
Authorize water utility budget funds for water conservation education, training, efficiency and
conservation upgrades to city facilities, including rebates, or financing, for rain sensors,
rainwater capture and use, and WaterSense certified appliances and devices installed on
private property.
Direct the Eagan water utility, with input from the Energy & Environment Advisory
Commission, to develop and implement a water conservation plan to achieve or exceed the
city’s water reduction goal.
Russ Matthys, Director of Public Works, had a couple of questions on the proposal from the
Subcommittee. Director Matthys asked if the water reduction rate was referring to residential or city
wide reduction. After discussion with Commission Members it was agreed to provide both options
for the Council to review. Director Matthys also indicated on page four of the proposal the first
Energy and Environment Commission October 8, 2013 Page 3

April 9, 2013
Page 3
sentence should be “Eagan Finance Director” instead of “Eagan CFO Pepper”. Member Bitner
motioned for the Energy and Environment Commission to express support for the Water Efficiency
Subcommittee recommendations dated April 2013 as amended above, Member Wisniewski
seconded, with all members voting in favor of the motion.
COMMITTEE UPDATES
PACE Funding for Renewable Energy and Energy Efficiency (Ross, Amir, Tim) - Director Johnson
stated this item is ready to go with your recommendation back to City Council.
Communications (Kari, Jon, Tim) – Member Drucker provided three communication items the
committee would like to be posted on the City of Eagan Facebook page. Director Johnson will review
items with City Staff and post once approval is received.
Member Nadav requested a recommendation for Communications to work with Dakota
Valley Recycling to have them provide the City regular content to post on the City of Eagan’s
Facebook page regarding waste reduction and recycling. Director Johnson stated Dakota Valley
recycling regularly provides information to post in other City of Eagan publications. Leigh Behrens is
the dedicated recycling/environmental technical person for the city of Eagan and also a Facebook
editor. Member Drucker will take this as an action item and follow-up on this directive.
Commission Members reviewed the waste haulers rate report contained in the packet.
Member Nadav thanked City Staff for compiling and posted these rates on our website. After further
brief comments by the Commission there was no more discussion.
STAFF REPORTS
Director Johnson gave verbal update on Coal Tar Sealant. The City Council directed this to be
forwarded to the City Attorney for review. The City Attorney stated the State of Minnesota is
considering legislation dealing with this topic. The City Attorney recommended waiting for the
legislation. The City Attorney had some reservations about having the ability to ban the sale of
something that is legal to sell in the State of Minnesota. After further discussion Commission
Members agreed to wait to see if the legislation passes in mid May before proceeding further.
Member LeClair requested an explanation from the City Attorney’s office explaining why this
ordinance change is being discouraged.
Russ Matthys, Director of Public Works, discussed a meeting he attended recently related to
diminishing groundwater levels in the metro area. Director Matthys would like to consider joining the
Southwest Metro Groundwater Group. This would be a proactive action and may preempt and
possibly help guide future decisions about the use and regulation of ground water in the metro area.
Member LeClair requested that any correspondence generated by this group be forward to the
Energy and Environment Commission for review. Member Bintner motioned that the Energy and
Environment Commission support the concept that the City of Eagan join the Southwest Metro
Groundwater Group to proactively lead in water conservation, Member Drucker seconded with all
present members voting in favor.
Director Johnson provided information regarding the going green carnival at Market Fest
June 19th. The Commission has the opportunity to have a booth and provide community outreach
and education on energy and environmental conservation topics. Director Johnson also provided
the Commission information on the upcoming Showcase Eagan on Sunday September 15 th. Item
was referred to the Communication Subcommittee for review and come up with a proposal for the
Commission. Deadline for the first event is April 26th. Commission Members briefly discussed
creating a residential survey that could be posted on the website for community input on
Energy and Environment Commission October 8, 2013 Page 4

Department of Transportation. Member Nadav will provide a link for those who are interested in this
topic. Member Nadav commented on a national complete streets report recently available. He
stated the City of Northfield was mentioned in this report as having one of the best complete streets
policy’s in the entire country. Member Nadav would encourage continued work on active living and
complete streets into the next work plan. There is a complete street workshop on May 16th an email

Landscaping Ordinance Committee
Recommendations for October 8, 2013 Meeting
Proposed overarching questions for discussion with the City Council:
1. What are the city of Eagan’s goals with respect to landscaping and maintenance of
vegetation in residential areas and on the adjacent public right-of-way?
2. To what extent should Eagan residents be allowed to plant vegetation or establish ground
cover other than turf grass on their yards?
3. To what extent should permitting processes be applied to landscaping projects? Are
clarifications or modifications to existing permitting processes appropriate?
Energy and Environment Commission October 8, 2013 Page 8
1. What are the city of Eagan’s goals with respect to landscaping and maintenance of
vegetation in residential areas and on the adjacent public right-of-way?
EEAC Findings:
a) The 2011 - 2012 City Council Goals included the following:
i. Maintain a broad-based and comprehensive commitment to energy efficiency and
environmental sustainability by adopting conservation and alternative energy strategies
pursuing the use of local, non-polluting, renewable, and recycled resources, while
encouraging residents and businesses to do likewise.
b) The purpose section of Code 10.21 “Planting and maintenance of trees and grass on
private property” states:
i. The regulations set forth in this section are for the purposes of protecting and promoting
the public health, safety and general welfare of the people of the city by regulating the
planting and maintenance of trees in order to protect trees and to prevent and abate
hazardous and nuisance conditions within the city.
2. To what extent should Eagan residents be allowed to plant vegetation or establish ground
cover other than turf grass on their yards?
EEAC Findings:
a) Current city code addresses meadows, woodland, turf grass, and noxious weeds. It is
mostly silent on edible vegetation, native grasses and forbs, ornamental plants, rain
gardens, and ground covers such mulch, gravel, or ornamental rocks.
b) According to University of Minnesota Extension, traditional turf lawns require 1 to 1.5
inches or water per week during the summer months. [1] For a 4,000 sq. ft. lawn, that
could amount to 44,000 gallons of water per summer. A quarter of an acre is equivalent
to 10,890 square feet.
c) A DNR test well shows that the average water level of Eagan’s aquifer has declined
approximately 35ft over a 35 year period. [2] The Metropolitan Council predicts a 20-40
foot drawdown of aquifer levels under the city of Eagan by 2030 under business as usual
conditions. [3]
d) In 2011, Eagan’s average daily water use was 13.2 million gallons of water per day in the
summer months and 5.8 million gallons of water per day in the winter months. [4]
e) Compared to traditional turf grass, native vegetation requires less moisture, fertilizers,
and pesticides and places less stress on the public’s water resources. [5]
f) Landscaping such as rain gardens filter and infiltrate stormwater, thereby protecting
surface water from polluted runoff and recharging groundwater resources. [5]
Energy and Environment Commission October 8, 2013 Page 9
g) Gas powered garden tools emit 5% of the nation's air pollution. Forty million
lawnmowers consume 200 million gallons of gasoline per year. One gas-powered
lawnmower emits 11 times the air pollution of a new car for each hour of operation. [6]
h) Minnesota is at risk of non-attainment with National Ambient Air Quality Standards for
particulates and ozone. Estimated cost of compliance with federal regulations for
nonattainment ranges from $140 - $260 million. [7]
3. To what extent should permitting processes be applied to landscaping projects, particularly
the items listed below? Are clarifications or modifications to existing permitting processes
appropriate?
Fencing
Raised beds
Landscaping within the Right-of-Way (ROW)
EEAC Findings
a) ROW and Zoning permits provide educational opportunities to help property owners
comply with codes and standards in their initial investments.
b) City staff members estimate that as many as 10-15% of zoning permit applications
submitted include structures or improvements that would have been in violation of
setbacks or other regulations if they had been installed as originally proposed.
Fences
a) A zoning permit is required for residential fences.
b) Communication with city staff has indicated that the permit may not be required for small
garden fences, although this is not stated on the permit form.
Raised Beds
A zoning permit is required for retaining walls less than 4 feet in height.
The permit requires submittal of
o Two copies of plans showing how the wall will be constructed, including plan
view, cross section and elevation drawings.
o Two copies of a site survey drawn to scale indicating the location of the wall on
the property, structures on the site, and all easements.
Benefits of raised beds include: [8]
o Handicap-accessible gardening
o Better drainage than in-ground beds
o Longer growing seasons due to warmer soil temperature
o Protection of soil and plants from foot traffic compaction
o Enabling gardening in challenging areas (e.g. above buried utilities, uneven slope,
contaminated soil.)
Right-of-Way
a) According to the Eagan Citizens Support Center:
i. Approximately 12-13 feet behind the curb is designated City Right-of-Way
Energy and Environment Commission October 8, 2013 Page 10
ii. The Right-of-Way is intended for underground utility installations and winter snow
storage and should be kept clear of any item that may be damaged.
iii. The City is not responsible for damage to sprinkler systems or other items located in the
Right-of-Way.
b) A permit is required for planting of trees, shrubs, or installation of landscaping or
irrigation systems within the city ROW.
c) City code requires the owner of the abutting property to maintain turfgrass or other
shrubs and landscaping within the ROW.
d) Landscaping within the ROW is fairly common in residential areas in Eagan. City staff
estimate that the majority of landscaping within the ROW was established without a
permit.
e) State law governing excavations that require utility locates does not apply to gardening
unless it disturbs the soil to a depth of 12 inches or more; trees or shrubs unless
disturbing to a depth of 18 inches or more (Statute 216D.01).
f) Examples of materials that other cities allow in the ROW and setbacks:
i. Eden Prairie city code states that the right-of-way boulevard is composed of regularly
mowed turfgrass, trees, shrubs, wood chips, rock, and/or gravel. It also permits garden
beds, in addition to the aforementioned items, in setback areas
ii. Edina city code states that the setback areas from streets, side and rear yards, shall be
composed of pavement, rock, gravel, wood chips, regularly mowed turfgassses, trees or
shrubs.
iii. St. Paul city code allows property owners to plant and maintain gardens and flowers in
boulevard areas adjacent to their properties. Vegetation is limited to 36” in height or 18”
in certain areas.
iv. Minneapolis city code states that flowers under 36” (or 18” in certain areas), grass, and
certain trees are allowed in the boulevard without a permit.

EAGAN ENERGY & ENVIRONMENT ADVISORY COMMISSION
WATER EFFICIENCY SUBCOMMITTEE RECOMMENDATIONS
October 2013
Actions for Consideration:
The Eagan Energy & Environment Advisory Commission recommends the following items to
City Council for consideration:
● Adopt a city-wide goal of reducing per capita daily water use 10% by 2020 and 15% by
2025 below a baseline of the average per capita daily water use from 2005 - 2010.
● Register the City in the free and voluntary WaterSense partnership program and appoint
the water utility to administer program implementation.
● Direct the Eagan water utility, with input from the Energy & Environment Advisory
Commission, to develop and implement a water conservation plan to achieve or exceed
the city’s water reduction goal.
Background information
The City of Eagan uses an average of 3 - 3.5 billion gallons of water each year and sends an
average 2 - 2.5 billion gallons of water each year to the Seneca Wastewater Treatment plant.
On a typical year, about 30% of the water used in the city of Eagan does not go down a drain,
some of which is composed of water uses classified under Minnesota Statutes as “sixth priority
non-essential uses.” While this water goes through an expensive treatment process, some non-
essential water uses such as lawn irrigation could be met in part through alternatives such as
rainwater, or reduced via rain sensors, water-efficient landscaping, and other mechanisms.
In the Summer of 2010, the City of Eagan implemented a water conservation rate structure.
Average summer water use has trended slightly lower in the first two years, although the impact
of the rate structure on annual city-wide water usage has not yet been determined.
Eagan’s water use over the past decade has remained relatively constant and trended slightly
downward since peaking in 2006. Nearly 70% of Eagan’s housing units were constructed before
1990. In 1992, new federal water efficiency standards were enacted, which reduce per capita
water usage for new construction and can improve the water efficiency through retrofits and
remodels to existing buildings.
As an example, toilets installed before 1990 used anywhere from 3 - 7 gallons per flush. Toilet
models today can use 1.6 gallons per flush, and high-efficiency WaterSense-certified toilets use
even less. Water efficiencies for dishwashers, washing machines, faucets, showerheads, and
other water-using devices have also improved.
The City of Eagan’s Water Supply and Distribution Plan projects a roughly 20% increase in
average per capita daily water use in Eagan and a 33% increase in per capita maximum day
Energy and Environment Commission October 8, 2013 Page 12
2
water use, compared to a projected increase in population of around 14% (see reference
material).1 To meet this growing need, the plan identifies investments in new supply and storage
of over $7 million. City staff note that of the $7 million figure in the plan, around $3 million is
intended for storage and not based on demand.
Communities across the country are achieving significant water savings by implementing water
efficiency programs. These programs may include a variety of approaches such as rainwater
harvesting, water efficient landscaping, and incentives to encourage private investment in the
existing building stock to improve water efficiencies partially in lieu of public investments in new
supply. Such an approach in Eagan may potentially offer a cost-effective use of resources with
co-benefits and complement, or partially offset, the 2008 Water Supply & Distribution Plan’s
projected investments of over $7 million in new supply and storage.

Action Item: Adopt a city-wide goal of reducing per capita daily water use 10% by 2020 and
15% by 2025 below a baseline of the average per capita daily water use from 2005 - 2010.
Background
According to the Metropolitan Council2:
Water pumped from aquifers has risen from approximately 20% of the Twin Cities 7-
county metropolitan region’s supply in 1950 to 70% today.
Aquifer levels are declining, in some locations as much as one foot per year.
By 2040 the region may add over 800,000 residents.
Conservation strategies have had an effect. Some communities have documented 20%
less water use per person over the past decade.
According to the Urban Land Institute’s Regional Indicators Initiative3:
Eagan ranked 3rd highest among the 20 Minnesota cities for total per capita daily water
use, and roughly 26% above the 20-city average.
Eagan ranked 4th highest among the 20 Minnesota cities for per capita residential sector
water use, and roughly 35% above the 20-city average.
WaterSense
Action Item: Recommend to City Council Approval of the WaterSense Partnership Agreement
and Designation of Eagan Water Utility as the Implementing Entity
Background
1 Potential reasons for growth include a new large industrial customer, redundancy in supply and conservative
engineering estimates.

WaterSense is a free and voluntary national partnership program among federal, state and local
government agencies, builders, manufacturers, water utilities, retailers and other entities. The
goal of the program is to encourage water conservation. WaterSense offers free educational
materials, technical assistance and a national certification for appliances and devices that are
20% more water efficient than conventional models as determined by independent, third-party
testing.
Since the program’s inception in 2006, WaterSense reports helping consumers save a
cumulative 287 billion gallons of water and over $4.7 billion in water and energy bills. As of
January 2013, over 3601 organizations across the country were WaterSense partners. Public
sector partners in Minnesota include the cities of Farmington, Oakdale, Roseville, Luverne,
Marshall Municipal Utilities, Rochester Municipal Utilities, Minnesota Department of Natural
Resources, Minnesota Pollution Control Agency, and the Minnesota Technical Assistance
Program.
GreenStep Cities provides credit for cities that implement educational programs and incentives
for use of WaterSense-labeled appliances. Joining the WaterSense program will provide the city
of Eagan with access to materials and assistance that will help the city complete GreenStep
best practice action 20.7 and enhance the city’s implementation of GreenStep action 2.5.
By joining, the city agrees to promote the value of water efficiency and the meaning of the
WaterSense label, provide annual data about city activities to promote water efficiency, feature
the WaterSense label on the website and promotional materials, and allow the U.S.
Environmental Protection Agency to recognize the city’s participation in the program. In return,
partners receive access to a partners-only website with free resources (such as tutorials, public
education materials, and access to a peer network of examples from other locales) that the city
may use to implement its water savings program.

Water Conservation Plan
Action Item: Direct the Eagan water utility, with input from the Energy & Environment Advisory
Commission, to develop and implement a water conservation plan to achieve or exceed the
city’s water reduction goal.
Background
A water conservation plan would identify a portfolio of strategies best suited for achieving the
proposed water conservation goal based on the opportunities and needs in Eagan. Potential
strategies that could be explored for consideration and potential incorporation into a water
conservation plan include:

● Install rain barrels, cisterns or surface water reuse on city facilities, where appropriate,
and utilize rainwater for grounds irrigation. Provide public education signage at high
visibility demonstration sites
● Install and expand low-water landscaping on city facilities, where appropriate, and
provide educational signage and tours at high visibility demonstration sites
● Provide regular water saving tips on city facebook page, newsletter, Eagan TV, city utility
bills
● Partner with energy utilities serving Eagan on the promotion and distribution of their free
water-saving kits for Eagan Households
● Provide educational seminars or tours for the public on water conservation, reuse, and
rainwater capture and use
● Offer water assessments for private properties to help identify opportunities for water
efficiency, conservation, and reuse
● Develop a financial incentive program to encourage water efficiency and conservation
upgrades on private property along with possibilities for reuse, and rainwater use
practices by prioritizing water utility funds for these activities over investments in new
storage and supply
● Explore, with Eagan CFO Pepper, revisions to the water utility conservation rate
structure to encourage conservation and equitable cost-allocation
● Explore enforcement mechanisms and penalties to discourage repeat violations of
existing water conservation ordinances

Toilets, Sink Faucets and Showerheads
6 According to the City of Eagan Public Works Annual report, actual maximum daily demand in 2010
equaled 18.7 million gallon/day, http://www.cityofeagan.com/upload/images/PublicWorks/Eng/ARUA.pdf
Energy and Environment Commission October 8, 2013 Page 17
7
The 1992 Federal Energy Policy Act required all toilets, sink faucets and showerheads
manufactured in the United States after January 1, 1994 be low-volume fixtures. Toilets
must use no more than 1.6 gallons per flush (gpf); sink faucets no more than 2.5 gallons
per minute (gpm); and showerheads no more than 2.5 gpm, respectively. Fixtures
installed before 1994 were not required to be retrofitted; therefore, 5 to 7 gpf toilets and
3 to 4 gpm sink faucets and showerheads are still in extensive use throughout the United
States.
Clothes Washers and Dishwashers
The efficiency of clothes washers and dishwashers installed between 1980 and the early
2000s are estimated to range from 27 gallons per load (gpl) to 51 gpl and 7 gpl to 14gpl,
respectively. Although recent models (since year 2000) are twice as water-efficient as
those of 20 years ago (1980), water conservation measures are still important because
as population increases so does total water use.
Implementation Status of Relevant GreenStep Cities Actions
Best Practice 20.7
Create a demand-side management program to reduce demands on water and wastewater
systems. http://greenstep.pca.state.mn.us/bestPracticesDetail_actions.cfm?bpid=20&aid=883
Status: Eagan has not yet reported completion of this action
Implementation Guidance (from GreenStep website)
○ 1 Star: Offer incentives to homes and businesses to reduce use of water and to limit
wastewater, such as using WaterSense rated appliances, smart lawn-watering
techniques, replacing old toilets, harvesting rainwater for landscaping, and water re-use
where appropriate and allowed under Minnesota code. Report building or development
code water efficiency, as part of Green Building efforts, under best practice 2, action 5.
○ 2 Stars: Achieve 1 Star rating AND study the cost-savings from deferring capacity
additions and reducing energy and maintenance operating costs if demand is reduced.
Report demand-reduction savings to residents and businesses.
○ 3 Stars: Achieve 2 Star rating AND modify rate structures to target peak-use times and
discourage or defer use, OR create a sustainable water use plan.
Best Practice 2.5
Energy and Environment Commission October 8, 2013 Page 18
8
Conserve drinking/groundwater resources by adopting a watering ordinance, conservation rate
structure, dynamic user feedback, model landscaping ordinance, or WaterSense purchasing
program. http://greenstep.pca.state.mn.us/bestPracticesDetail_actions.cfm?bpid=2&aid=725
Status: Eagan has reported implementing a tiered rate structure and odd-even watering.
Implementation is complete at a 1 star level. The city’s information on the GreenStep website
appears below.
The City of Eagan has permanent conservation program for outside water usage. If your address
ends in an odd number such as 311, outdoor watering is allowed on the 1st, 3rd, 5th, 7th, etc.,
day of the month. If your address ends in an even number such as 312, outdoor watering is
allowed on the 2nd, 4th, 6th, 8th, etc., day of the month. This permanent system is in effect
throughout the entire outdoor watering season. The State has enacted legislation requiring cities
with a water utility to adopt a rate structure that encourages water conservation. To comply with
the law, most cities, including Eagan, have chosen to adopt a tiered rate structure. Eagan has a
two-tier system in place. Effective July 1, 2010 residents pay the same rate they are accustomed
to paying$1.40 per thousand gallons for the normal indoor usage. The normal usage level will be
defined as water used in the winter quarter, a period void of outdoor use such as watering lawns,
washing cars, and filling swimming pools. Water used in the non-winter quarters in excess of
normal will be billed at $1.75 per thousand gallons." found on the Cities web page at
http://www.cityofeagan.com/live/page.asp?menu=21444.
Implementation Guidance (from GreenStep website)
○ 1 Star: Implement a robust water ordinance OR robust conservation rate structure.
Report water use changes (which can be reductions of around 10%) or the rate
structure/pricing.
○ 2 Stars: Modify and adopt a model landscaping ordinance that encourages low water-
use landscaping, OR arrange for water users to see their water use history/use
compared to similar users.
○ 3 Stars: Achieve 1 Star rating AND create a rebate or feebate program to promote
purchases of WaterSense- and/or Energy Star-rated appliances, consistent with best
practice 20, action 5. Report on rebates granted by appliance type and estimated
water/energy savings.
