Renewable energy is a valuable resource.Removing barriers to this resource will ensure
community inclusiveness. It will allow all residents and businesses to capture the benefits of
appropriately designed and sited renewable energy sources.Operational effectiveness will be
achieved with the removal of barriers and promotion ofrenewable energy. It will assist the City in
meetingits Comprehensive Plan energy goals. One of the goals states that the City will encourage
and support renewable energy by obtaininga minimum of 50 percent of all electric energy from
renewable sources by 2040.
Background
During the September 17, 2018, Environmental and Natural Resources Commission meeting, the
Commission finalized its review of the Renewable Energy Ordinance amendments. The
Commission held off on making a motion on the ordinance amendments until they reviewed the
SolSmart presentation in October.
Cameran Bailey, SolSmart Advisor with the Metropolitan Council, presented details of the SolSmart
programduring the October 15, 2018, Commission meeting. Maplewood is currently designated at
the Silver Level. To achieve the Gold Level the City needs to enact a three-day review process for
solar permits. The presentation also detailed additional resources for promoting solar energy in the
community including:
Solar PV building and structure integration
Supporting existing policies, goals, and strategies with solar PV
Potential social, environmental, and economic co-benefits of solar PV deployment
Renewable Energy Ordinance Amendments
Following is a summary of the proposed renewable energy ordinance amendments:
Wind
Electrical Grid: Remove the requirement that a wind energy system be connected to the
electrical grid.
Neighborhood Consent: Require60 percent neighborhood consent instead of 100 percent
for a ground mounted residential wind energy system.
Wind Energy Systems in Parks: Allow wind energy systems in parks with the same controls
as allowed in other zoning districts.
Setbacks: Modification of wind energy system setbacks.
Solar
Electrical Grid: Remove the requirement that a solar energy system be connected to the
electrical grid.
Screening: Modified the screening requirements for solar energy systems.
Community Solar Gardens: Added language that would regulate community solar gardens.
Geothermal
No proposed changes to the geothermal section of the ordinance.
Solar Permittingand Design Review
Building permit fees: Commercial solar permits are based on the cost of the job. In
December the CityCouncil will be considering a reduction in the residential solar permitfees
to a flat $200fee.
Community solar gardenconditional use permit fees: The proposed ordinance amendment
requires ground mounted community solar gardens to obtain a conditional use permit.
Conditional use permits cost $1,650 to process. In December the City Council will be
considering a reduction in the community garden conditional use permit fees,half the cost of
a regular conditional use permit. The reduction in fees is warranted since community
gardens do not require review of a building or detailed engineering plans, and will help
promote local foods in the City. The same is true for community solar gardens. They do not
require review of a building or detailed engineering plans, and will promote renewable
energy in the City. The Environmental and Natural Resources Commission should offer
comment and feedback on the fees for community solar garden conditional use permits.
Commercial and multi-family solar and community solar garden design review requirements:
Exterior improvements to a commercial or multi-family building require design review by the
City. If the projectis $200,000 or less, the project can be reviewed administrativelywith a
15-day review which costs $500.All new commercial or multi-family development (including
community solar gardens), and project to existing commercial or multi-family developments
that are over $200,000, would require design review by the Community Design Review
Boardwhich costs $1,650. The Environmental and Natural Resources Commission should
offer comment and feedback on requiring commercial and multi-family buildings and ground
mounted community solar gardens to receive design review approval for solar projects.

ORDINANCE NO. _____
An Ordinance Regulating Renewable Energy Systems (Wind, Solar, Geothermal)
The Maplewood City Council approves changes to Chapter 18 (Environment), Article V
(Environment and Natural Resources), Division 5 (Renewable Energy) as follows:
Section 1. Scope.
This ordinance applies to the regulations of on-siterenewableenergy systems within the City of
Maplewood,Ramsey County, MN.The ordinance focuses on wind turbines,solarsystems, 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 asustainable 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. Citiesare 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, Maplewoodbelieves 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. WhileMaplewood strongly encourages increased energy
conservation and improved energy efficiency, the city also finds that increased use of
appropriate renewableenergy 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 renewableenergy systemswith concerns for preservation ofpublic health,
welfare, and safety, as well as environmental quality,visual and aesthetic values, and existing
neighborhoodsocial andecological stability.With these regulations, Maplewood is concerned
that renewableenergy systems, particularly windenergy systems, be designed to minimize the
negative impacts on bird and bat species which are vulnerable to mortality from these energy
gathering machines.
