Report Overview
Page 2
This Report provides information on an amendment to Clarington's Property Standards
Bylaw 2007-070, for the inclusion of a nuisance lighting provision, in response to Council's
request.
1. Background
1.1 At the September 14, 2020 Joint Committees meeting, Council considered
correspondence from Raymond Kiomall requesting Council to enact a by-law to
regulate nuisance lighting and referred the correspondence to staff to report back.
1.2 Issues regarding nuisance lighting are seldom brought to the attention of the Municipal
Law Enforcement Division. Over the past five years, our dispatch records reflect that
only two concerns have been brought forward related to residential lighting being a
nuisance for residential areas.
1.3 Current Municipal regulatory by-laws do not address nuisance lighting for residential
lighting.
1.4 During the September 14, 2020 Joint Committee meeting, Council did raise questions
regarding residential lighting issues and commercial lighting issues. According to the
Municipal Law Enforcement Division dispatch records, approximately five concerns
have been reported concerning commercial lighting. As was conveyed to Council by
the Acting Director of Planning Services, commercial lighting is regulated through the
site plan process and as well, the Property Standards By-law 2007-070 also addresses
light trespass from Commercial Properties. See Attachment 1.
2. Discussion
2.1 Mr. Kiomall's correspondence referred to the Town of Ajax's Property Standards Bylaw
and suggested that Clarington enact similar regulations. Staff reached out to the Town
of Ajax and confirmed that their Property Standards By-law 46-2017 states as follows:
Exterior lighting fixtures shall be installed and maintained so as to prevent the
light source from shinning directly into a dwelling unit
2.2 Ajax enforcement staff indicated they infrequently have to rely on this regulation but
admitted that it has proven useful when it was appropriate to apply it. They further
noted that the regulation purpose is specifically for direct lighting and is not intended for
light trespass.

Report LGS-001-20
2.3 Should Council choose to enact a regulation to regulate direct lighting as a nuisance
(not light trespass) emanating from residential properties, staff recommends that the
Property Standards By-law be amended to include the same clause as is used by the
Town of Ajax (stated in 2.1 above).
3. Concurrence
Not applicable.
4. Conclusion
Should Council wish to regulate direct lighting emanating from residential properties, it
is respectfully recommended that the By-law attached to this Report as attachment 2 be
approved.

Re: Lighting in Commercial and Industrial Developments
At the Joint Committee meeting of the September 14t", Councillor Neal raised regarding
lighting requirements/standards for commercial and industrial developments. This
memo has been prepared in response to those concerns.
Council approved Lighting Guidelines in March 2010. The purpose of the Lighting
Guidelines is to provide effective measures to mitigate the impacts of excess and
unnecessary external lighting. The guidelines are used as part of the site plan approval
process for new development applications for commercial, industrial, institutional and
multi -unit residential developments. The guidelines were introduced to address
concerns about direct glare and light trespass. They are not intended for municipal
street lighting or residential development. The guidelines can be found hers.
Lighting plans are required as part of the site plan approval process. Applicants are
required to submit a Photometric Lighting Plan, prepared by a qualified design
professional.
The standard requirement is for full cut-off lights (e.g no light trespass across the
property boundary). These are lights designed and/or shielded in such a way that all the
light rays emitted by the fixture are project below the horizontal plane. In other words,
as much as possible the light shines down, rather than in a larger circumference or up
into the sky.
The guidelines establish a set of maximum illumination values for different lighting
zones. The zones range from lighting requirements for sensitive land uses, for example
agricultural and natural areas which require low level illumination to urban uses, such as
commercial plazas, dealerships, and institutional uses where higher level illumination is
permitted.

Once the Site Plan is approved, the Owner enters into a Site Plan Agreement. The owner
agrees to install the lighting in keeping with the approved Photometric Lighting Plan. Once
all the new site lighting has been installed on the subject lands, the owner agrees to obtain
a letter from the project's lighting engineer certifying that the lighting has been installed in
accordance with the approved drawings, prior to release of the landscape securities.
In the case of Owasco, site plan approval was issued in July 2018. The municipality
does retain landscape securities. These securities will not be released until the
certification from the consulting engineer has been received.
If you have additional questions, please contact Cynthia Strike.

APPROVED BY COUNCIL ON
MARCH 22, 2010
PREFACE
In 2005, the area municipalities of Durham Region began the process of formalizing the review criteria of lighting systems
for new development and redevelopment proposals subject to site plan approval. The municipalities, comprising
representation from the Durham Regional Planning Department, Town of Ajax, Township of Brock, Municipality of
Clarington, City of Oshawa, City of Pickering, Township of Scugog, Township of Uxbridge, and Town of Whitby, formed a
committee, known as the Inter -municipal Lighting Committee, in order to develop a set of Lighting Guidelines. Lumetech
Engineers Inc. was retained to provide expert advice and assist in the development of the technical data. The Durham
Region Astronomical Association (DRAA) also provided input and advice for the Guidelines.
The purpose of the Lighting Guidelines is to provide a set of effective standards, consistent across the Durham Region,
that are designed to mitigate the impacts of excess and unnecessary external lighting. These Guidelines are intended to
be used as part of the site plan approval process for new development applications. Proponents installing new lighting
systems or retrofitting existing systems as part of the site plan process should refer to these Guidelines and ensure that
they are in compliance with all requirements herein.

LIGHTING GUIDELINES
1. PURPOSE
The purpose of these guidelines is to provide a set of
effective standards designed to limit the impacts of
excess and unnecessary external lighting. Specifically,
these guidelines are intended to be used as part of the
site plan approval process for new development
applications.
These guidelines are not intended to regulate lighting for
single family dwellings (including single detached
dwellings, semi-detached dwellings, linked dwellings, and
street townhouse dwellings) or municipal street lighting.
Figure 1: Urban Sky Glow Effect
PAGE 1
2. BACKGROUND
Excessive and unnecessary site lighting can have a
number of detrimental environmental and safety impacts.
Specifically, excessive lighting can be inefficient in terms
of energy consumption, as well as create glare levels that
can be a detriment to drivers, pedestrians and
neighbouring properties. From an environmental
perspective, the over lighting of towns and cities creates
a phenomenon known as Urban Sky Glow (refer to
Figure 1), that renders the night sky effectively
unviewable to town and city dwellers. Furthermore, poor
outdoor lighting design can create light trespass which is
a nuisance that can negatively affect the enjoyment of a
person's property.
The uneven application of lighting standards can create
issues around transition; moving from an under lit area to
an over lit one. This can have a significant effect on the
night vision of drivers, cyclists and pedestrians.
These guidelines are designed to mitigate these issues
through introducing standards that will address concerns
about direct glare and light trespass. In addition, these
standards factor in safety issues, such as those
addressed by Crime Prevention Through Environmental
Design (CPTED) principles and, in particular, safety
issues that pertain to shadowing, peripheral visual
detection and clarity of vision, with respect to seeing
other people and objects.
MUNICIPALITY OF CLARINGTON
LIGHTING GUIDELINES
3. SCOPE
The scope of the lighting guidelines is to create a set of
standards that are applicable for land uses across
Clarington. These guidelines are intended to address,
but are not limited to:
• Lighting for buildings and structures, including
building entrances, canopies or overhangs;
• Parking lot lighting;
• Pedestrian and landscape lighting;
• Recreational area lighting;
• Display, service and advertising lighting;
• Wall mounted lighting;
• Security lighting;
• Ornamental/decorative lighting;
• Lighting in heritage areas.
4. AUTHORITY
The Planning Act, through Bill 51, allows for lighting
studies to be requested as part of the municipal site plan
process. As such, applicants will be required to submit
information from a qualified lighting design professional
with respect to any proposed external lighting as part of
the site plan process. The required information will
include:
• Light fixture (luminaire) design sheets, containing:
o Lamp (bulb) types;
o Fixture specifications (full cut-off required);
• Lighting Plan in foot candle values showing
photometric data (refer to Figure 2), containing:
PAGE 2
o Pole specifications such as height, spacing and
placement; and
o Photometric information, showing areas of
illuminance illustrated with isometric lines.

5. LIGHTING FIXTURE REQUIREMENTS
A wide number of lighting fixture designs and lamp types
exist today. Light sources, or lamps, are available in a
variety of styles. Each lamp type has different attributes
and can be installed where most suitable. For example,
metal halide lamps and LED lamps produce a white light
which is ideal when colour rendering is required for
purposes such as security. High pressure sodium, on the
other hand, produces a yellowish light that is ideal when
colour rendering is not required. This is an appropriate,
energy efficient lamp for purposes such as ornamental or
accent lighting.
Apex
PAGE 3
The issue of light fixture design refers to the nature of the
fixture itself. The standard requirement is for full cut-off
lights. These are lights that are designed and/or shielded
in such a way that all of the light rays emitted by the
fixture are projected below the horizontal plane. In
technical terms, there should be no light emission at the
vertical angle of 90 degrees or greater above the nadir
(the point at ground level directly below the source of
light), and no more than 10% at the angle of 80 degrees
above the nadir (refer to Figure 3).

LIGHTING GUIDELINES
6. ILLUMINATION REQUIREMENTS
In addition to setting standards for acceptable lamps and
fixture types, these guidelines have established a set of
maximum illumination values for different Lighting Zones.
The illumination requirements are expressed in the form
of tables pertaining to each Lighting Zone's maximum
illumination at the property line (refer to Appendix 1).
The lighting zones are intended to recognize that not all
areas can achieve the same lighting levels. At the pre -
consultation stage, the applicant will work with the
Planning Services Department to determine which
Lighting Zone the proposal falls under. Four Lighting
Zones have been established. Lighting Zone 1 is the
most stringent and includes environmentally sensitive
and open space areas. The majority of development
proposals will be designated as part of Lighting Zone 2.
Locations with unique constraints and dense
development may be classified as Lighting Zone 3. The
Lighting Zone 4 designation is reserved for those sites
with extreme constraints, requiring special consideration.
Lighting Zone 4 will typically constitute development
within downtown areas.
Non -essential external lighting is encouraged to be
switched off during non -operating hours, or placed on
senor -activated timers (where lighting does not serve
security purposes).
PAGE 5
The land uses that these guidelines will apply to are:
• Commercial uses such as plazas, retail outlets, car
dealerships, offices, personal service uses, and
others;
• Industrial uses such as warehousing, manufacturing,
fabrication, aggregate extraction and processing
uses;
• Institutional uses such as, places of worship, schools
(public and private), hospitals, and government
facilities;
• Recreational uses such as golf courses, driving
ranges, soccer pitches, domes and baseball
diamonds and ski hills;
• Residential uses with three or more units (save and
except for street townhouses) and retirement homes.

7. SUBMISSION REQUIREMENTS &
STANDARDS
When requested, site plan applications should be
accompanied by a lighting plan and lighting fixture details
that demonstrate that the proposal meets the guidelines.
The following submission requirements and standards
will apply:
Unacceptable
Unshielded
Fixtures
Acceptable
"Full cutor I~"
Full cutoff or shielded
Fixtures I
"Colonial -type" fixtures
Figure 9: Lighting Fixture Examples

7.1 GUIDING STANDARDS
• Light fixtures should be positioned across a site so as
to give a uniform distribution of light over the relevant
area. This assists in the avoidance of the creation of
"hot spots" (areas of over -illumination that make
adjacent areas seem darker);
• The conservation of energy should be encouraged;
• Lamps shall be located in such a way as to direct light
away from neighbouring properties;
• Except where lighting is strictly ornamental,
photometric performance (the glare, intensity and
uniformity of the light produced) will be a more
important factor in assessing the suitability of
proposed lighting than aesthetics;
• Only down -lighting or back lighting will be permitted
for on -site signage;
• Areas as identified as unsafe or provide security
concerns may require additional lighting based on
CPTED principles.
7.2 LIGHTING FIXTURE SUBMISSION
REQUIREMENTS
• Detail specifications, including lamp type, fixture type,
lumens rating of lamp, wattage, colour, etc. shall be
submitted;
• Only full -cut off fixtures shall be accepted;
• Fixtures shall be positioned such that they focus light
down, preventing light from emitting above the
horizontal plane (90 degree position relative to the
ground) and preventing light trespass.
MUNICIPALITY OF CLARINGTON
LIGHTING GUIDELINES
7.3 LIGHTING PLAN SUBMISSION REQUIREMENTS
• The illumination levels shall be expressed in foot
candles and in the form of isolux curves showing the
predicted lighting levels at the property line and
throughout the development site;
• Pole specification such as height, spacing, foundation
details, and placement shall be provided. Pole heights
will generally be between 6.0 metres (for smaller,
pedestrian scaled development) and 7.5 metres for
larger scale development. Municipal recreation uses,
such as baseball diamonds, are not regulated by
these guidelines;
• Lot boundaries must be shown;
• Location of all structures must be shown;
• Location and height of all proposed luminaires,
including wattage, and lamp type must be shown;
• The illumination levels at all property lines should
strive to achieve `01 foot candles;
• A photometric diagram showing the predicted lighting
levels from each of the proposed light sources shall
be provided;
PAGE 7
• The lighting plan is to be signed by the qualified
lighting design professional responsible for the plan;
• Five (5) copies of the lighting plan and fixture details
are to be included in the final submission.
7.4 UNIFORMITY RATIOS
In lighting design the average maintained illuminance and
uniformities are calculated. The uniformity ratio is
computed to make sure that certain minimum levels are
achieved in the design, creating uniform lighting across a
site. For outdoor lighting applications, Average to
Minimum ratio is considered essential in order to control
the creation of "hot spots", which are areas with very high
illumination that are surrounded by darker areas. As part
of a lighting plan submission, designers are required to
submit the Average to Minimum ratio, which is to be
designed in accordance with the Illuminating Engineering
Society (IES).

LIGHTING GUIDELINES
APPENDIX 2: DEFINITIONS
Foot Candles: Lumens per square foot.
Illuminance: The amount of light that actually falls on an
object. It is the density of light on a particular surface —
measured in lux or lumens per square foot (foot candles
— fc).
Lamp: A bulb or other light producing source.
Light: Visible wavelength energy that enables you to
see.
Light Pollution: The overall impact that the lighting of
cities and towns has on the night sky.
Light Trespass: The projection of light from one site
onto another.
Lumens: Measurement of the total amount of light
emitted by a bulb, known as luminous flux. A 100 watt
incandescent bulb will put out roughly 1,800 lumens,
while a high pressure sodium street lamp of the same
wattage will emit about 8,550 lumens.
Luminaire: The lighting fixture itself. It is a combination
of the bulb, socket, reflectors or lenses, ballast, and
housing.
PAGE 10
Luminance The light that the eye sees — i.e., light that
has been reflected by a surface. It is measured in
Candelas per square foot or metre.
Lux: The measure of illuminance, expressed in units of
Lumens per square metre.
Metal Halide: Produces white light, which the eye sees
well for scotopic vision. The yellow light produced by low
and high pressure sodium is not seen well by the eye in
low light situations.
Pole Height: Height of a light standard, measured from
the grade (ground level) to the highest point on the
luminaire.
Qualified Lighting Design Professional: A person with
the appropriate qualifications to design lighting systems.
This may include those with the L.C. (lighting
certification) or Professional Engineers registered in
Ontario in Electrical Engineering. Others with similar
credentials may be considered Qualified Lighting Design
Professionals on a case by case review.
Vertical Illuminance: Lighting levels measured on the
vertical plane at a height of 1.5m (5ft) above ground
level. This is a normalized observer eye height, and
represents effects on humans at eye level.
