SUBJECT: Chicken Ordinance Update
DATE:March 2, 2011, for the March 7 City Council Workshop
INTRODUCTION
Urban communities throughout the country are considering allowing chickens in residential
areas as a way of promoting urban agriculture and sustainability. There has been an interest by
some Maplewood residents and the Environmental and Natural Resources (ENR) Commission
to allow chickens in Maplewood for this purpose as well. Maplewood’s zoning code prohibits
the raising or handling of poultry (including chickens) in all single dwelling residential zoning
districts.
BACKGROUND
In October 2009 the ENR Commission began to review the feasibility of allowing chickens in
residential zoning districts as a means of promoting more sustainable food products. Since that
time the Commission has reviewed comments from residents, the Maplewood Animal Control
Officer, Chief of Police, and Health Officer in regard to this matter. Staff has conducted
research on other cities in the metropolitan area that have developed chicken ordinances.
The comments reflected both positive and negative impacts due to the raising of chickens in
residential areas. Positive impacts include homeowners producing their own organic eggs and
using the manure for garden fertilizer. The main negative impacts outlined by staff were
possible nuisance complaints from neighbors.
After review of the research and comments, the ENR Commission recommended approval of an
ordinance on July 19, 2010, which would allow up to ten chickens on a residential lot of any size
with a permit. The permit can only be approved if at least 75 percent of the property owners
within 150 feet consent to the permit. The ENR Commission attempted to address all of the
possible negative impacts of raising chickens in residential areas with regulations such as
prohibiting roosters (noise impacts), requiring chickens to be housed in chicken coops located in
the back yard, requiring chickens to be contained in a fenced area, requiring chickens to be
banded for identification in the event they get loose, and prohibiting the slaughtering of chickens
on the property.
In August and September 2010, the Planning Commission reviewed the chicken ordinance.
Several issues were raised by the Commission during the review including requiring larger lot
sizes, requiring 100 percent of the neighbors to approve of a permit, concerns about permit
cost, and chicken coop and run placement. After two meetings, the Planning Commission
recommended denial of the ordinance by a vote of four to three, with some of the
commissioners who voted against the ordinance indicating they would be more supportive of the
ordinance if additional protections were built in for surrounding residential properties such as
requiring larger lots for the keeping of chickens, etc.

Inspection: required before issuing a license
A chicken may be humanely euthanized or sold after it has been impounded for a
violation of the ordinance and no owner has claimed the chicken within five business
days.
Permit Cost
Before the ENR Commission proceeded with the review of allowing chickens in residential
zoning districts, they wanted to ensure the ordinance would not cost taxpayers money. They
requested that staff estimate the time and costs associated with administration and enforcement
of chicken permits. Following are the costs associated with impounding and boarding a stray
chicken, the Animal Control Officer’s fee schedule, and estimates on administrative time and
costs for processing a permit:
Enforcement: In the case of a chicken nuisance in Maplewood, the Animal Control Officer
would address the issue. It may be necessary to impound the chicken after a complaint. The
City of Maplewood sends all stray domestic animals to the Hillcrest Animal Hospital. Fees for
the cost of enforcement and impounding of a chicken are listed below:
3
PacketPageNumber5of61
Fee Charge
Animal Control Officer Time (hourly fee) $38.00/hour
Animal Control Officer Time (call out fee) $82.00
Impound Chicken (Hillcrest Animal Hospital) $42.00
Boarding Chicken (Hillcrest Animal Hospital) 18.00/day or $102-for up to 6 days
If the Animal Control Officer had to pick up and impound a stray chicken, the cost would be $82
for a call out fee and $42 to impound the chicken ($124). If an owner did not pick up a chicken
that same day, the fee would increase $18 a day, for a maximum of six days (up to $232). After
six days the animal becomes the property of Hillcrest Animal Hospital, who would attempt to find
a home for the animal. On some occasions, however, an animal may need to be euthanized.
Permit: The permit process would include a property owner submitting an application and fee to
the Community Development Department. City Planners would review the permit to determine
if all required materials were submitted including a review of the zoning and neighborhood
consents. Once the permit is reviewed, the City Planners would forward the permit to the
Animal Control Officer for an initial inspection. If the inspection was approved, the City Planner
would sign off on the permit and submit it to the city’s Licensing Clerk, who would process the
permit and ensure annual reviews.
Staff estimates that it would take a City Planner approximately one hour to complete their work,
the Animal Control Officer’s review and inspection would take one hour, and the Licensing Clerk
would take one hour to input and process the permit. Overall staff time is estimating that it
would take three hours to process a chicken permit on average. Based on this estimate and
using the Animal Control Officer’s hourly fee of $32 an hour, the city should charge $96 for an
initial permit in order to recoup costs. Less could be charged for the annual renewals as that
would not require as much time to process.
If a chicken ordinance were adopted with a permit requirement, the City Council would set the
fees associated with permitting on an annual basis. After review of the above estimates, the
ENR Commission stated that a fee of $96 would be cost prohibitive for an applicant and the city
could probably process the permits for less time and money. They based this on research from
cities that allow chickens with a permit. The ENR Commission recommended Maplewood
charge the fees currently being charged by the City of Minneapolis, $50 for a permit and $30 for
a renewal. Minneapolis representatives have stated these fees cover their costs. The ENR
Commission recommended the city monitor the fees to ensure coverage of administrative and
enforcement costs. If the fees are found to be too low, the city council could adjust the fees
during their annual fee reviews.
Since the ENR Commission’s recommendation, staff reviewed the process and fees associated
with dog and cat permits for comparison. The city issues a dog or cat permit at city hall or by
mail. An applicant submits an application, fee, and proof of rabies vaccination and the city
issues the permit. Permits run for two years with a fee of $21.00 for a non-spayed or non-
neutered dog or cat ($19.00 if the owner is a senior) and $18.00 for a spayed or neutered dog or
cat ($16.00 if the owner is a senior). The dog and cat permit process takes less time than the
proposed chicken permitting process, which would require verification of neighbor consent and
a site inspection.

Proposed Ordinance Amendment
Residential Zoning:
1. Following is an amendment proposed to the Maplewood Zoning Code that would allow
chickens in residential areas (additions are underlined and deletions are stricken from
the original ordinance):
Chapter 44 (Zoning), Article II (District Regulations), Division 3 (R-1 Residence District)
Sec. 44-6. Definitions.
Poultry means domesticated birds that serve as a source of eggs or meat and that
include among commercially important kinds, chickens, turkeys, ducks, geese, peafowl,
pigeons, pheasants and others.
Sec. 44-103. Prohibited uses.
The following uses are prohibited in the R-1 Residence district:
(1) The raising or handling of livestock, poultry (except for chickens as outlined in
Sections 10-476 through 10-487, Chickens) or animals causing a nuisance,
except for licensed kennels.
2. Most of the city’s single dwelling residential zoning districts have a permitted and
prohibited uses section. The R-1 zoning district lists the specific uses, and subsequent
single dwelling zoning districts should refer to those same uses as well. There are five
single dwelling residential zoning districts as follows: R-1, R-1S, RE-30,000, RE 40,000,
and R-1R. Two of those single dwelling zoning districts (R-1R and R-1S) do not have
the reference to permitted or prohibited uses, and as such require an amendment as
follows:
Chapter 44 (Zoning), Article II (District Regulations), Division 5 (R-1S Small-lot Single
Dwelling District)
Sec. 44-192. Permitted uUses.
(1) Permitted uses. The only permitted uses allowed in the R-1S small-lot single-
dwelling district are the permitted uses in the R-1 district.
(2) Prohibited uses.
(a) Accessory buildings without an associated dwelling on the same
premises.
(b) The raising or handling of livestock, poultry (except for chickens as
outlined in Sections 10-476 through 10-487, Chickens) or animals
causing a nuisance, except for licensed kennels.
Chapter 44 (Zoning), Article II (District Regulations), Division 3.5 (R-1R Rural
Conservation Dwelling District)
5
PacketPageNumber7of61
Sec. 44-118. Uses.
(a) …
(b) …
(c) Prohibited uses. The city prohibits the following uses in the R-1R zoning
district:
(1) Accessory buildings without an associated single dwelling on the
same property.
(2) The raising or handling of livestock, poultry (except for chickens
as outlined in Sections 10-476 through 10-487, Chickens) or
animals causing a nuisance, except for licensed kennels.
Animals:
Following is proposed language which would specify the permitting requirements for chickens in
residential areas. All of the proposed language is new and would be added to the animal
chapter of the city code. Much of the language is reflective of the city’s existing dog section of
the animal ordinance.
Chapter 10 (Animals), Article IX (Chickens)
Sec. 10-476. Definitions.
Brooding means the period of chicken growth when supplemental heat must be
provided, due to the bird’s inability to generate enough body heat.
Chicken means a domesticated bird that serves as a source of eggs or meat.
Coop means the structure for the keeping or housing of chickens permitted by the
ordinance. Coop may be permitted with or without a run.
Hen means a female chicken.
Officer means any person designated by the city manager as an enforcement officer.
Rooster means a male chicken.
Run means a fully enclosed and covered area attached to a coop where the chickens
can roam.
Sec. 10-477. Purpose.
It is recognized that the ability to cultivate one’s own food is a sustainable activity that
can also be a rewarding past time. Therefore, it is the purpose and intent of this
ordinance to permit the keeping and maintenance of hens in a clean and sanitary
manner that is not a nuisance to or detrimental to the public health, safety, and welfare
of the community.
6
PacketPageNumber8of61
Sec. 10-478. Investigation and Enforcement.
Officers designated by the city manager shall have authority in the investigation and
enforcement of this article, and no person shall interfere with, hinder or molest any such
officer in the exercise of such powers. The officer shall make investigations as is
necessary and may grant, deny, or refuse to renew any application for permit, or
terminate an existing permit under this article.
Sec. 10-479. Limitations for each dwelling unit in residential zones.
(1) No more than ten (10) hens shall be housed or kept on any one residential lot in
any area of the city zoned for single dwelling residential with a permit as outlined
below.
(2) Roosters are prohibited.
(3) Slaughtering of chickens on the property is prohibited.
(4) Leg banding of all chickens is required. The bands must identify the owner and
the owner’s address and telephone number.
(5) A separate coop is required to house the chickens.
(6) Chickens must not be housed in a residential house or attached or detached
garage, except for brooding purposes only.
(7) Chicken coops and runs are limited to the rear yard only.
(8) Chicken coops and runs require at least a five (5) foot setback to the side and
rear property line.
(9) All premises on which hens are kept or maintained shall be kept reasonably
clean from filth, garbage, and any substances which attract rodents. The coop
and its surrounding must be cleaned frequently enough to control odor. Manure
shall not be allowed to accumulate in a way that causes an unsanitary condition
or causes odors detectible on another property. Failure to comply with these
conditions may result in the officer removing chickens from the premises or
revoking a chicken permit.
(10) The coop must be constructed and maintained so as to be rodent proof.
(11) All grain and food stored for the use of the hens on a premise with a chicken
permit shall be kept in a rodent proof container.
(12) Hens shall not be kept in such a manner as to constitute a nuisance to the
occupants of adjacent property.
Sec. 10-480. Permit required.
The officer shall grant a permit for chickens after the applicant has sought the written
consent of seventy-five (75) percent of the owners or occupants of privately or publicly
owned real estate within one hundred fifty (150) feet of the outer boundaries of the
7
PacketPageNumber9of61
premises for which the permit is being requested, or in the alternative, proof that the
applicant’s property lines are one hundred fifty (150) feet or more from any structure.
Consent is also required where a street separates the premises for which the permit is
being requested from other neighboring property if it meets the distance requirements
specified above. Where a property within one hundred fifty (150) feet consists of a
multiple dwelling or multi-tenant property, the applicant need obtain only the written
consent of the owner or manager, or other person in charge of the building. Such written
consent shall be required on the initial application and as often thereafter as the officer
deems necessary.
Sec. 10-481. Application.

(2) The breed and number of chickens to be maintained on the premises.
(3) A site plan of the property showing the location and size of the proposed chicken
coop, setbacks from the chicken coop to surrounding buildings (including houses
and buildings on adjacent lots, and the location, style, and height of fencing
proposed to contain the chickens). Portable coops and cages are allowed, but
portable locations must be included with the site plan.
(4) Statements that the applicant will at all times keep the animals in accordance
with all of the conditions prescribed by the officer, or modification thereof, and
that failure to obey such conditions will constitute a violation of the provisions of
this chapter and grounds for cancellation of the permit.

the council pursuant to this article, or with any state or local law governing cruelty to
animals or the keeping of animals. Any person whose permit is revoked shall, within ten
days thereafter, humanely dispose of all chickens being owned, kept or harbored by
such person, and no part of the permit fee shall be refunded.
RECOMMENDATION
The ENR Commission has recommended approval of the chicken ordinance after several
months of review and research into the subject matter. The Planning Commission
recommended denial of the chicken ordinance after two reviews by a vote of four to three, with
some Commissioners who voted against the ordinance indicating they would be more
supportive of the ordinance if it offered additional protections to surrounding property owners
such as requiring larger lots for the keeping of chickens, etc. City staff receives a few calls a
month with inquiries from residential property owners wanting to keep chickens on their
property. City staff has invited these property owners to attend the March 7 workshop. Prior to
moving forward with the chicken ordinance, staff is recommending that the City Council review
the draft ordinance (as outlined above) and offer feedback.

MEMORANDUM
TO: James Antonen, City Manager
FROM: Shann Finwall, AICP, Environmental Planner
SUBJECT: Renewable Energy Ordinance Update
DATE: March 2, 2011 for the March 7 City Council Workshop
INTRODUCTION
The city adopted an energy efficiency and conservation strategy in December 2009. The
strategy was required as part of the city’s energy efficiency conservation block grant. One
purpose for the strategy is to help establish policies and priorities to move Maplewood in the
direction of improved long-term operational energy efficiency.
Implementation of the strategy includes the adoption of energy policies that will ensure
achievement of the city’s energy goals. The renewable energy ordinance, which will assist in
the promotion of renewable energy sources throughout the city, will help Maplewood meet that
goal. During the March 7, 2011, workshop, staff will update the City Council on the proposed
ordinance which addresses regulations for wind, solar and geothermal energy sources.
BACKGROUND
George Johnson, senior scientist with SEH, drafted the renewable energy ordinance for the
Environmental and Natural Resources (ENR) Commission’s review in early 2010. Since that
time the ordinance has gone through a number of reviews and changes. Nick Carver, assistant
building official, reviewed the ordinance for building code compliance. Melissa Doperalski,
central region ecologist with the Minnesota Department of Natural Resources, reviewed the
ordinance for environmental considerations, particularly placement and design of wind turbines
to lessen impacts to birds and bats. The ENR Commission recommended approval of the
renewable energy ordinance on December 9, 2010.
In January and February 2011, the Planning Commission began their review of the renewable
energy ordinance. During their review, the Planning Commission expressed concern over
allowing wind turbines in residential zoning districts.
DISCUSSION
Following is a brief summary of the regulations proposed for wind, solar, and geothermal energy
in the renewable energy ordinance:
Wind
Large Wind Energy Conversion System (WECS):
Definition:Large WECS - A WECS of equal to or greater than 100 kW in total nameplate
generating capacity. These are commercial grade wind turbines. The energy must be used on-
site with excess energy distributed into the electrical grid.

constant temperature of the earth or a body of water to provide heating in the winter and cooling
in the summer. System components include closed loops of pipe coils or plates and fluid that
absorb and transfers heat and a heat pump unit that processes heat for use or disperses heat
for cooling and an air distribution system. The energy must be used on site.
Location: A permitted use in any zoning district
Placement: Setback at least 5 feet from interior and rear lot lines. GSHPS can be located
within stormwater ponds.
RECOMMENDATION
The ENR Commission has recommended approval of the renewable energy ordinance. The
Planning Commission will continue their review over the next few months. Prior to moving
forward with that review, staff is recommending that the City Council review the draft renewable
energy ordinance and offer feedback.

ORDINANCE NO. XXX
DRAFT 7 (January 11, 2011)
AN ORDINANCE TO THE MAPLEWOOD MUNICIPAL CODE REGARDING
RENEWABLE ENERGY SYSTEMS (Wind, Solar, Geothermal)
The Maplewood City Council approves the following addition to the Maplewood Code of
Ordinances. This ordinance creates a new renewable energy ordinance which will be placed in
the Environment Chapter (Chapter 18) of the city code.
Section 1. Scope.
This ordinance applies to the regulations of on-site renewable energy systems within the City of
Maplewood, Ramsey County, MN. The ordinance focuses on wind turbines, solar photovoltaic
systems, and geothermal ground-source heat pumps which are located on the site for which the
generation of energy will be used, with excess energy distributed into the electrical grid.
Section 2. Purpose and Intent.
It is the goal of the city to provide a sustainable quality of life for the city’s residents, making
careful and effective use of available natural resources to maintain and enhance this quality of
life. Cities are enabled to regulate land use under Minnesota Statutes 394 and 462 for the
purpose of “promoting the health, safety, morals, and general welfare of the community.”
As part of this regulatory power, Maplewood believes it is in the public interest to encourage
renewable energy systems that have a positive impact in energy conservation, with limited
adverse impact on the community. While Maplewood strongly encourages increased energy
conservation and improved energy efficiency, the city also finds that increased use of
appropriate renewable energy systems will be an important part of improving urban
sustainability.
The renewable energy regulations are intended to supplement existing zoning ordinances and
land use practices, and ensure these systems are appropriately designed, sited and installed.
These regulations are in place to balance the need to improve energy sustainability through
increased use of renewable energy systems with concerns for preservation of public health,
welfare, and safety, as well as environmental quality, visual and aesthetic values, and existing
neighborhood social and ecological stability. With these regulations, Maplewood is concerned
that renewable energy systems, particularly wind energy systems, be designed to minimize the
negative impacts on bird and bat species which are vulnerable to mortality from these energy
gathering machines.
Section 3. Wind Energy Sources and Systems

AGENDA REPORT
TO:
James W. Antonen, City Manager
FROM:
Nick Carver, Assistant Building Official/Green Building Manager
Charles Ahl, Assistant City Manager
SUBJECT:Green Building Program Presentation
DATE:
February 28, 2011 for the March 7, 2011 Council Workshop
INTRODUCTION
Nick Carver, the Maplewood Assistant Building Official/Green Building Manager, will give a
presentation to the City Council regarding the city’s proposed “Green Building Program”.
BACKGROUND
The intent of this program is to present the International Green Construction Code and the
National Green Building Standards as the base documents for a responsible jurisdictional
“Green Building Program”. The contents and philosophy of these documents insure an equal
understanding of sustainability and cost effective energy saving outcomes for present and future
generations. This program allows jurisdictions to lead by example by adopting the mandatory
options for city buildings and providing an array of incentives to residents and the business
community by choosing the voluntary option.
This program is more than a rating system. It can be used by manufacturers, design
professionals, contractors, building department and jurisdictional leadership. Creating these
partnerships leaps ahead of the curve in establishing what is a revolutionary movement in the
built environment. Jurisdictions are now able to customize a program to meet geographical and
political agendas by using the minimum standards, special jurisdiction requirements and project
electives.
DISCUSSION
Maplewood Building Division staff has acquired the knowledge, training, experience and vision
to implement this program. In addition this “Green Building Program” is an instrument to
accomplish the 2010-2012 City Council Goals. The program objectives can be matched to the
council goals as such:
The Building Department Division has developed a
1. Restore Reputation of Maplewood
“Green Building Program” that demonstrates sensible leadership by a professional and
dedicated staff. This program and the partnerships constructed will help to re-establish
Maplewood’s reputation as a viable community leader with a good management team
and financial stability.
PacketPageNumber27of61
2. Good Government Jurisdictional leadership has presented this program to all the various
City Boards in an open and transparent format. All leadership and staff have been
trained and partnered together to customize this program to create the best possible
program to date.
3. Parks and Recreation Department This program protects park land, open space, water
and conservation areas as part of its minimum requirements. Maplewood is not only a
Green place to live and work, but is also a Green place to play.
4. Environmental Planning All the homes and commercial buildings in Maplewood use
energy and water. The primary purpose of this program is to efficiently reduce the use of
those resources without decreasing resident’s standard of living and promote
businesses ability to thrive. The decisions we make today will improve the quality of life
for generations to come.
5. Fiscal Responsibility By adopting this program Maplewood leadership leads by example.
The city’s priorities are focused on doing what’s right the first time by accurately
researching the possibilities boldly moving forward knowing the risks and the rewards.
6. Infrastructure All city buildings are currently being evaluated to meet the requirements of
the International Green Construction Code for existing buildings and existing building
sites. This policy will immediately begin to upgrade Maplewood buildings in a step by
step organized fashion with positive results.
7. Redevelopment Plan The city Master Plan will include the use of existing developments,
greyfields and brownfields. Existing buildings are the foundation for “Green”
redevelopment and all efforts shall be made to save and use those resources.
RECOMMENDATION
It is recommended that the City Council review the content of the material presented and
determine the course of staff to adopt this “Green Building Program” as a City of Maplewood
policy or ordinance.
