EXECUTIVE
SUMMARY
Assumptions and
Analysis:
An interim report is being presented to the Committees at this time in order to generate discussion on lighting options and costs, on the recommended lighting approach set out within the draft policy and to receive comments on the completion of a final Right-of-Way Lighting Policy. The project terms of reference approved by Council last year directed that staff return with an interim report and present a final draft policy for consideration at a later date.
The Right-of-Way Lighting Policy study has been ongoing since the spring of 2006 and has involved the Planning, Transit and the Environment and Public Works and Services, Departments, City Advisory committees, external stakeholders, interest groups and the general public. The draft policy covers street and sidewalk lighting for all urban and rural parts of the city. The policy was formulated based on the principles of energy conservation, mitigation of light pollution and cost savings. The policy addresses lighting requirements in various contexts including, for example, the completion of lighting in existing development areas and lighting upgrades for unlit roadways. The policy identifies two distinct areas for right-of-way lighting - “Special Areas” and “All Other Areas”. Decorative lighting equipment is proposed for lighting “Special Areas” and standard lighting equipment is proposed for “All Other Areas”. The policy references land use areas within the Official Plan for clarity on where the two lighting standards would apply.
The policy introduces new approaches to right-of-way lighting, including lower roadway lighting levels and requiring mandatory use of full cut-off (0% up light) luminaires on local streets in all new residential and employment areas, consideration of the use of full cut-off luminaires for all other right-of-way lighting applications, reducing lamp wattages for marker-type lighting in urban and rural areas, and providing guidelines for lighting installations adjacent to Urban Natural Features.
The study also investigated and considered the implementation of emerging technologies such as Light Emitting Diodes (LED), induction lighting, solar power and “smart lighting technology” in an attempt to find cost-effective alternatives to the current street lighting equipment. Changes to right-of-way lighting in existing communities are not proposed except for upgrades to marker lights where there is no street lighting, and in Special Areas of the city at the time of major relighting or road reconstruction. These changes would be undertaken incrementally over time based on Council-approved capital and operating funding at the time of major road reconstruction or relighting.
A cost estimate to undertake a future study to establish lighting regulations on private land adjacent to the public rights-of-way, which would compliment the Right-of-Way Lighting Policy, is discussed in the report.
Financial
Implications:
If the decorative
lighting approach in the draft Policy is approved as attached to this report,
the following additional average annual budget increases would be
required: $417,000 capital and $17,700
operating budgets for 2.5kms/year decorative lighting on reconstructed roads in
Special Areas and $12,100 operating for 1.0kms/year decorative lighting on new
roads in Special Areas. The total per
year can be rounded up to $500,000.
These averages were based on actual construction/reconstruction of roads
in the last five years but are subject to change based on actual construction
programs and decorative lighting styles selected. The detailed financial implications of approving the draft Policy
are discussed in the body of the report.
The consultant cost of approximately $50,000 for the possible
preparation of a Lighting Zone Study is also discussed in the body of this
report.
Public
Consultation/Input:
The details of consultation with the public,
Advisory Committees and stakeholder groups are set out in Document 3.
RÉSUMÉ
Hypothèses et analyse :
À l’heure
actuelle, un rapport provisoire est présenté aux comités afin de susciter des
discussions sur les options d’éclairage et les coûts, sur l’approche de
l’éclairage recommandée énoncée dans le projet de politique et dans le but de
recevoir des commentaires sur l’achèvement d’une version définitive de la
Politique sur l’éclairage des emprises. Conformément au mandat du projet
approuvé par le Conseil l’an dernier, on demandait que le personnel présente un
rapport provisoire ainsi qu’une version définitive de la politique pour prise
en considération à une date ultérieure.
L’étude sur la
Politique sur l’éclairage des emprises est en cours depuis le
printemps 2006 et les services de l’Urbanisme, du Transport en commun et
de l’Environnement, Services et Travaux publics, les comités consultatifs de la
Ville, des intervenants externes, des groupes d’intérêt et le grand public y
participent. Le projet de politique couvre notamment l’éclairage des rues et
des trottoirs pour toutes les parties urbaines et rurales de la ville. La
politique a été formulée selon les principes de la conservation de l’énergie,
de la réduction de la pollution par la lumière et de la réduction des coûts. La
politique aborde les besoins d’éclairage dans divers contextes, y compris, par
exemple, l’achèvement des travaux d’éclairage dans les secteurs résidentiels
actuels et l’installation de lampadaires sur les routes où il n’y a pas
d’éclairage. Dans la politique, on soulève deux secteurs distincts pour ce qui
est de l’éclairage des emprises, soit les « secteurs particuliers »
et « tous les autres secteurs ». On propose un matériel d’éclairage
décoratif pour l’éclairage des « secteurs particuliers » et un
matériel d’éclairage standard pour « tous les autres secteurs ». La
politique renvoie aux secteurs d’utilisation des terres dans le Plan officiel
pour plus de précision sur les cas où les deux normes d’éclairage s’appliquent.
La politique
présente de nouvelles approches de l’éclairage des emprises, y compris des
niveaux d’éclairage routier moins élevés et l’utilisation obligatoire de
lampadaires à défilement total (0 % d’éclairage dirigé vers le haut) dans
les rues locales de tous les nouveaux secteurs résidentiels et centres
d’emploi, envisager l’utilisation de lampadaires à défilement total pour toutes
les autres applications d’éclairage des emprises, réduire le wattage des
ampoules pour l’éclairage de repérage dans les zones urbaines et rurales et
fournir des lignes directrices pour les installations d’éclairage adjacentes
aux espaces naturels urbains.
Dans le cadre de
l’étude, on a également examiné et envisagé la mise en œuvre de technologies
émergentes, comme les diodes électroluminescentes (DEL), l’éclairage par
induction, l’énergie solaire et la « technologie d’éclairage
intelligent » dans le but de trouver des solutions de rechange rentables à
l’équipement d’éclairage que l’on retrouve actuellement dans les rues.
Dans les
collectivités actuelles, on ne propose pas de modifications à l’éclairage des
emprises, à l’exception de l’installation de lumières de repérage où il n’y a
pas d’éclairage de rue et dans les secteurs particuliers de la ville au moment
de l’installation massive de nouveaux lampadaires ou de la remise en état des
routes. Ces modifications seront apportées graduellement au fil du temps en
fonction du financement d’immobilisations et de fonctionnement approuvé par le
Conseil au moment des grands travaux de réfection des routes ou de
l’installation de nouveaux lampadaires.
Dans ce rapport,
on discute entre autres de l’estimation des coûts nécessaires pour mener une
étude éventuelle visant à établir les règlements régissant l’éclairage sur les
terrains privés adjacents aux emprises publiques et qui compléterait la
Politique sur l’éclairage des emprises.
Répercussions financières :
Dans le cas où
l’approche de l’éclairage décoratif dans le projet de politique est approuvée
telle qu’elle est jointe au présent rapport, les augmentations suivantes du
budget annuel moyen seront nécessaires : un budget d’immobilisations de
417 000 $ et un budget de fonctionnement de 17 700 $ pour
2,5 km/année d’éclairage décoratif sur les routes reconstruites dans les secteurs
particuliers et un budget de fonctionnement de 12 100 $ pour
1,0 km/année d’éclairage décoratif sur les nouvelles routes dans les
secteurs particuliers. Le total par année peut être arrondi à
500 000 $. Ces moyennes sont basées sur les chiffres réels de la
construction/reconstruction des routes au cours des cinq dernières années, mais
peuvent changer selon les programmes de construction actuels et les styles
d’éclairage décoratif choisis. Les répercussions financières détaillées
découlant de l’approbation du projet de politique sont abordées dans le corps
du rapport. On discute également dans le corps du rapport des coûts des
services de l’expert-conseil (approximativement 50 000 $) pour la
préparation possible d’une étude sur les zones d’éclairage.
Consultation publique / commentaires :
Les détails de la
consultation avec le public, les comités consultatifs et les groupes
d’intervenants sont présentés dans le Document 3.
BACKGROUND
In 2001 a residential street lighting policy that
harmonized street lighting methods used by the former municipalities was
approved for the city. Since that time
the need to address a broader range of lighting approaches specific to
community context, and to provide further opportunities for innovation within
the policy has become evident. Public
Works and Services (PWS) staff began a comprehensive update to the harmonized
street lighting policy in 2003. A
considerable amount of inventory work and formulation of criteria necessary to
evaluate possible approaches to Citywide street lighting was completed under
PWS direction. This project was paused
to re-examine the range of lighting opportunities that should be addressed in
the formulation of the policy.
In 2005 interdepartmental discussions with Public
Works and Services resulted in an agreement to have the then Planning and
Growth Management Department participate as an equal partner in the formulation
of the new Right-of-way Lighting Policy so that it could be dovetailed with the
related “Street Design” project.
Council approved the terms of reference for the Right-of-Way Lighting
Policy and the Street Design Policy studies in the spring of 2006.
The intent of the new Right-of-way Lighting Policy
is to clarify the range of permitted types of lighting, determine appropriate
lighting levels in various city contexts, and establish areas where changes to
the existing street light system are warranted. It also provides direction for specific circumstances or
geographic areas in which specialty lighting is appropriate. Within this report on the draft Right-of-way
Lighting Policy are estimated costs to undertake a subsequent study looking at
implementing “lighting zones”, which would limit the maximum light level on
development sites adjacent to the roadway in selected locations of the
city.
The related Street Design policy will be brought to Committee for consideration under separate cover later this year. Updates related to hydro burial and placement of right-of-way lighting are part of the street design policy, which incorporates all other aspects of surface treatment including sidewalks, benches, trash receptacles, bollards, bike racks etc.
DISCUSSION
Study Process
Planning, Transit and the Environment, in collaboration with Public Works and Services Department undertook this project. Staff from a range of branches within the City were provided the opportunity to participate in the decision-making process through the establishment of a Technical Advisory Committee (TAC). City Advisory Committees were also consulted. External stakeholders, interest groups and the general public were also given the opportunity to participate through various circulations, project meetings and two Public Open Houses.
The project commenced in April 2006 with the
development of a “Strategic Directions” discussion paper that provided an
overview of possible lighting options for all parts of the city. The Strategic
Directions document was circulated to City Departments, technical agencies and
stakeholder groups, and was presented to several City Advisory Committees for
input. The first draft of the policy was developed in the fall of 2006 based on
the comments received from the circulation of the Strategic Directions
document. The first draft of the policy
was circulated to various committees, external stakeholders and interest groups
for review and comment late in 2006. The draft policy subsequently was revised
and presented to the public at two Public Open Houses; one in the urban area at
City Hall and the second in the rural area in the Village of Richmond.
The urban area open house was well attended and many
comments were received from the public.
The rural area Open House was not as well attended and fewer comments
were received as a result.
The Open House information as well as the draft
Right-of-Way Lighting Policy was made available on the internet at www.ottawastreetlighting.ca
(accessible through the City’s project site on “Ottawa.ca”) for review by the
public that were unable to attend the Open House meetings. The open house meetings were advertised in
the Citizen and LeDroit as well as several rural weekly newspapers. Also, notice was emailed directly to all
registered community groups. In general, the response to the first draft policy
from the public, committees, external stakeholders and interest groups was
positive. Comments received from the open house meetings, Advisory Committees
and stakeholder groups are set out in Document 3.
Where appropriate, the draft policy was revised to reflect the comments received as a result of the consultation process. Comments received from the Committees and from the public as a result of the presentations of the draft will be used to develop the final draft of the policy. The final draft will then be submitted again to the three Committees and Council late in the summer of 2007 for approval.
Study Organization
The Technical Advisory Committee (TAC) provided recommendations to the core study team in the development of the policy. The TAC comprised City staff from Planning, Transit and the Environment and Public Works and Services. City Advisory Committees were circulated project information and were invited to review and provide comments. Presentations were made to several of the circulated committees in the summer of 2006 and winter 2007. The Advisory Committees involved included Roads and Cycling, Pedestrian and Transit, Parks and Recreation, Rural Issues, Environmental, Taxi, Seniors, Forests and Greenspace, Accessibility, Health and Social Services, Business, Local Architectural Conservation, and Arts, Culture and Heritage. Stakeholders, interest groups and technical agencies consulted in the development of the policy included the Royal Astronomical Society of Canada, Hydro Ottawa, Ottawa Police/CPTED, Fire Services (Urban), Fire Services (Rural), National Capital Commission, Utilities Coordinating Committee, Developer Liaison Group Steering Committee, Ottawa Carleton Home Builders Association (OCHBA), and Building Owners and Managers Association of Ottawa (BOMA).
Right-of-Way
Lighting Policy Overview
General Structure:
The policy contains general design requirements applicable to right-of-way lighting in all locations in the city. For the purpose of identifying select areas to receive decorative lighting, the policy divides the city into two distinct areas: “Special Areas” and “All Other Areas”. The purpose of assigning certain areas of the city to receive decorative lighting is to improve the urban design quality of the streetscape in areas of high pedestrian usage. This in turn may promote increased nighttime use by citizens in these areas of higher density residential and/or commercial activity.
Right-of-way lighting for each of the two lighting policy areas will be selected from a specified list of equipment tailored to each area context. The “Special Areas” are identified primarily in Ottawa’s Official Plan Schedules and include the Central Area, Mixed Use Centres / Town Centres, Arterial and Traditional Mainstreets, Heritage Conservation Districts, Business Improvement Area (BIA) mainstreets, Rural Village mainstreets and “Core Areas” (small town centres such as the future core area located within Riverside South).
Where these “Special Areas” are not identified in the Official Plan, (BIAs, Village mainstreets and Core Areas) the Right-of-Way Lighting Policy contains schedules identifying the location. City rights-of-way not located within the identified Special Areas are deemed to be within the “All Other Areas” policy area for lighting purposes.
The Right-of-Way Lighting Policy applies to roadways and sidewalks within public rights-of-way under the jurisdiction of the City. It does not apply to private properties, parks, open spaces, and pathways. It also does not apply to federal, provincial and greenbelt area roadways or to transitways. Right-of-way lighting on these roadways will be undertaken on a project-by-project basis in cooperation with and approval from the respective roadway authority. Since commencement of the study, Planning and Growth Management was restructured to include the transit portfolio. Staff will review the inclusion of the lighting of transitways as part of the preparation of the final draft of the Right-of-Way Lighting Policy.
At present, there are over 100 different styles of streetlights in the city. Many of the existing luminaires do not have “cut-off” lighting optics and therefore contribute to light pollution and result in wasted energy. The draft policy reduces the number of approved streetlights to 25, comprised of 13 standard and 12 decorative fixtures and associated poles. Only efficient semi-cut-off (maximum 5% direct up light) and full cut-off (0% direct up light) luminaires have been included in the approved equipment list. Of the 25 approved luminaires, five are listed both in the “decorative” and “standard” groups of equipment resulting in a total future inventory of 20 luminaire styles. Also, the Policy permits lighting equipment in Heritage Conservation Districts (HCD) to be selected from either an existing HCD light fixture, from one lighting style from the approved “decorative” lighting group or one “custom” fixture that more accurately represents the heritage nature of the district. Lighting of HCDs is under the control of the City. Several of the HCDs have existing decorative light fixtures on some streets. If the City selected a new custom fixture for each existing HCD, an additional 12 fixture styles could be added to the City’s overall lighting inventory.
All 13 standard fixtures are part of the existing 2001 Residential Street Lighting Policy and therefore have a proven performance track record. Five of the decorative fixtures are also part of the existing 2001 Residential Street Lighting Policy. There are 10 decorative poles and eight standard poles proposed. Of the 18 poles, three are listed both in the “decorative” and “standard” groups of equipment resulting in a total future pole inventory of 15 pole styles.
The majority of streets and sidewalks in the city
are located within the “All Other Areas” lighting policy area and therefore
will be lit with the “standard lighting” equipment with a high-pressure sodium
(yellow) light source. High-pressure sodium light is the existing light type
found on most city roads. Over the long
term, as streets are relit as part of regular lifecycle upgrades, the lighting
inventory will be reduced to the 20 approved styles. This will result in cost savings in maintenance and operation.
“Special Areas” will be lit with decorative lighting equipment with a metal halide (white) light source. Some city streets are already lit with metal halide light but at present it is more commonly found in commercial lighting applications. Laurier Avenue in front of City Hall is an example of a street lit with metal halide light. The style of decorative lighting equipment to be installed in all Special Areas will be selected through a future public consultation process. This could be as part of the preparation of a Community Design Plan or environmental assessment process.
Equipment must be selected from the approved group of decorative lighting equipment except in the case of lighting for Heritage Conservation Districts where a custom lighting design that better reflects the nature of the District may also be chosen.
Decorative lighting
installations with a metal halide light source has higher capital and operating
costs compared to standard equipment, discussed in financial section of this
report, but offers several benefits including:
New Approaches to Right-of-Way Lighting:
Several new approaches to right-of-way lighting are
proposed in the draft policy.
Highlights include the following:
a) City of
Ottawa Official Plan – The draft policy is
linked to the Official Plan map schedules to provide defined boundaries for all
“Special Areas”. The policy uses roadway classification terminology found in
the Official Plan and in the Transportation Master Plan. As the Official Plan
is updated from time to time the Right-of-Way Lighting Policy will
automatically apply to new and modified Special Areas.
b) Addition of
Decorative Lighting Equipment – The policy now
includes decorative fixtures for use in designated “Special Areas”. The use of
the decorative fixtures will highlight and distinguish these recognized
“Special Areas” as unique to their surroundings. To provide flexibility in addressing a variety of lighting design
contexts in Special Areas with the 12 decorative luminaires, three possible
configurations for lighting installations are provided for as follows:
·
Stand alone tall-height
poles (applicable to Arterial mainstreets),
·
Tall-height poles in
combination with a single short-height pedestrian scale pole located midway
between each pair of tall poles. The
tall-height pole may also be fitted with a decorative pedestrian-scale
luminaire (applicable to all Special Areas), and
·
Mid-height poles
(applicable to all Special Areas with the exception of arterial mainstreets
with wide pavement design).
c) Context-Based
Applications – The policy identifies several
lighting situations and provides direction for the installation of right-of-way
lighting. Highlights of the context-based applications include the illumination
of:
a.
New residential,
employment, and mixed-use centre area development: In these
areas there is a requirement on local streets to use full cut-off luminaires
and the maximum level of illumination is set at one-half of that recommended by
the Illuminating Engineering Society of North America (former City of Ottawa
standard).
b. Completion of Existing Subdivision Development:
Existing
lighting equipment style and level of illumination will be required to be
installed up to the nearest adjacent arterial or collector road regardless of
developer ownership. Approved lighting
equipment and level of illumination as set out in the new policy would be
required to be installed in the balance of the community.
c.
Infill Development: Lighting
equipment style and level of illumination that matches or is complimentary with
the adjacent lighting style found in existing development would be required for
infill developments on public roads.
Equipment would be selected from the approved styles in the policy.
d.
Existing Lighting
Installations: Methods for undertaking future lighting projects
along existing rights-of-way in rural and urban areas are set out in the
policy.
d) Design Requirements and Considerations – The policy provides direction on dealing with various lighting design factors. Highlights include:
a.
Establishing the
required minimum lighting levels specific to right-of-way classification
(arterial, collector, local) and highlighting the importance of not excessively
exceeding this level,
b.
Mitigating light
pollution such as light trespass onto private property, ‘sky glow’ and light
glare which can be disabling to the uses of the right-of-way.
c.
Identifying that
street trees along the right-of-way may shade the lighting thereby seasonally
reducing the lighting levels on the right-of-way and that tree trimming will
only take place under special circumstances.
d. Requiring transition illumination from lit to unlit
rights-of-way to help the driver adapt when a vehicle enters / exits the area.
e.
Directing that
lighting equipment is to be attached to existing utility poles where practical
to save costs.
f.
Identifying that
lighting of rights-of-way owned or under the control of other upper-tier
government authorities will be in accordance with the respective authority’s
policies.
e) Lower Light
Levels – The policy reduces the lighting level
requirement for new local roads in urban residential and employment areas to
one half the recommended Illuminating Engineering Society of North America
(IESNA) levels. This one-half IESNA level is the standard used for many years
for local and collector roads in the former City of Ottawa. There is no legal
requirement to light to the IESNA recommended levels. The reduced levels would result in energy cost savings (refer to
Financial section of this report) and reductions in light pollution (sky glow,
glare and light trespass). Recent installations of one-half IESNA light levels
can be seen at Staten Way in the Central Park community and full IESNA light
levels can be seen on Sunvale Way in
Barrhaven. The marker lighting (street
lighting located only at road intersections and super mailbox locations)
wattage standard has been reduced from 150 to 100 watts. In addition, marker lights at all super
mailbox locations must be full cut-off style (0% up-light).
f) Full
Cut-Off Luminaires (Flat Glass) – Full cut-off
luminaires emit 0% up-light into the sky. The City is currently using this
style of fixture on a limited number of streets but the majority of streets
have been lit with the Semi Cut-Off (5% up light) luminaires. In the draft
Right-of-Way Lighting Policy, flat glass luminaires are mandatory for use on
local streets in new residential and employment areas. The full cut-off fixture would also be given
first consideration in any right-of-way lighting design application as opposed
to automatically selecting the semi cut-off fixtures.
g) New Sidewalk
Lighting Levels – The existing Residential Street Lighting Policy, 2001
has lower light levels for all City sidewalks than are recommended by IESNA.
The draft policy maintains the existing 2 lux standard (IESNA is 3 lux) for
sidewalks on local roads to correspond with the proposed lower light levels
(one-half IES) for the street. The
sidewalk lighting levels for collector roads is proposed to be increased to
meet the recommended IESNA lighting levels.
Collector sidewalks would increase from 2 lux to 3 lux and major collector
sidewalks from 2 lux to 5 lux. For
sidewalks along arterial roadway classifications, the level of illumination
would need to be increased from 5 lux to 20 lux if the most restrictive IESNA
light level was met. This would result in a significant overlighting of the
roadway in order to light the sidewalk. Therefore in keeping with the
recommendations of the policy in not “over lighting” City roadways it was
decided to lower arterial sidewalk levels by 50% from 20 Lux to 10 Lux, which
is the same as the resultant light level from the backlighting of the roadway
lighting system. All sidewalks will be
lit to the minimum standards in the policy through “backlighting” provided by
the roadway lighting system. No
separate dedicated sidewalk lighting systems will be installed in the
city. However, decorative pedestrian
scale lights may be installed in certain of the Special Areas.
h) New Approach
to Urban / Rural Lighting Upgrades – The
existing City policy is to upgrade existing streets in the urban area and in
rural estate residential and village subdivisions that are unlit, have marker
or partial lighting to a “full continuous” lighting standard. Under the
existing approach, these upgrades to existing streets would take place over
time when normal lifecycle replacement occurs or major road reconstruction is
undertaken and based on approved capital funding. Under the proposed policy,
changes (upgrades) are not proposed to right-of-way lighting in existing
communities except in the case of upgrading to marker lights where there is no
street lighting and in Special Areas to decorative lighting at the time of
major relighting or major road reconstruction.
Changes in these two circumstances would be undertaken incrementally over
time based on Council-approved capital, maintenance and operating funding.
i) Urban
Natural Features – In recognition of possible
adverse effects of right-of-way lighting on birds, animals, plants and trees,
the policy addresses right-of-way lighting adjacent to Urban Natural Features
(woodlot areas) as identified by the City’s Urban Natural Features Strategy.
The policy identifies measures that must be undertaken to minimize the impact
of right-of-way lighting on Category 1 and 2 Urban Natural Features areas.
j) Light
Pollution – With mandatory use of Full Cut-off
luminaires and the reduction of lighting levels by 50% on local streets in new
residential, employment, and mixed-use centre areas, and given the fixture
consideration in all right-of-way lighting; light trespass, glare and ‘sky
glow’ are reduced. The lamp wattage of
marker lighting in urban and rural areas is proposed to be reduced by 33% from
150 watts to 100 watts, thereby also reducing the amount of ‘sky glow’, glare
and light trespass. The policy also
requires that all lighting fixtures used in the city must be at a minimum, of
semi-cut-off class i.e. the maximum allowable ‘direct uplight’ must be 5% as
opposed to fixtures that have unlimited ‘direct uplight’. This limit of 5% will
reduce the overall amount of ‘sky glow’ within the city.
k) Energy
Conservation – In recognition of rising energy
costs and the desire to reduce green house gas emissions, several measures are
proposed in the policy to reduce the overall energy consumption in right-of-way
lighting. The measures include the reduction of lighting levels on local
streets in new residential, employment and mixed-use centre areas by 50% (i.e.
one half IESNA lighting levels) as well as reduced lamp wattage in rural area
marker lighting by 33% (150 watts lowered to 100 watts).
l) Luminance Method – The existing way of undertaking lighting calculations in the City uses the “Illuminance” method. The new policy proposes use of the Luminance method that takes into account what the driver can actually see in terms of the reflected light off the pavement. Luminance will take precedence in roadway lighting designs. The Illuminance method, however, is proposed to continue to be used to calculate intersection and sidewalk lighting levels as well as unique roadway lighting design situations where the Luminance method is inadequate.
m) Glare Criteria – The use of glare criteria is now also being
introduced in the Policy to be used as part of the lighting design process to
ensure that the quality of right-of-way lighting is neither disabling nor obtrusive
to the users of the right-of-way.
n) National and
International Roadway Lighting Standards – The
policy was developed using the Guide for
the Design of Roadway Lighting by the Transportation Association of Canada
and the RP-8-00 Roadway Lighting by
the Illuminating Engineering Society of North America as benchmarks. In some
instances the policy refers directly to the Guide
for the Design of Roadway Lighting for recommendations and guidelines on
performing lighting warrant analysis and transition lighting.
Emerging Technologies:
The lighting industry is currently undergoing changes with respect to the available types of equipment. These changes include new types of lamps such as light emitting diode (LED) and induction lighting as well as smart systems that can provide variable lighting levels as part of a central control system. In addition, it is expected that solar powered lighting systems will become more commonplace as the luminaire wattages decline. New lighting technologies considered but not recommended for adoption in the policy at this time are as follows:
Even with the expected energy savings, their payback period is
approximately 7.5 to 14 years. Again,
this technology should be revisited in future updates of the policy.
Right-of-Way Lighting Policy Implementation:
The Right-of-Way Lighting Policy will be
administered by the Public Works and Services Department. In the draft policy,
the Director, Traffic and Parking Operations has the discretionary authority to
vary from the requirements of the policy for unique lighting circumstances not
specifically addressed by the policy. Any new area designations for either
“Special Areas” or new right-of-way designations in “All Other Areas” will apply
without amendment to the policy.
The policy requires review and updating from time to
time. Since the policy references the Official Plan, the review will occur to
coincide with the five-year update of the Official Plan or at an earlier date
as may be required to reflect changes in lighting technology. Minor changes will be made at the staff
level by Public Works and Services Department in consultation with Planning,
Transit and the Environment Department.
More substantive changes, involving changes in lighting technology (i.e.
such as incorporating LED lighting as a new standard) will be brought to
Committee for consideration.
There is now an approved list of lighting equipment
for both “Special Areas” and “All Other Areas” from which all right-of-way
lighting project selections must be made. This approved list helps control the
inventory of lighting equipment and reduces both maintenance and operational
costs. Staff may revise the approved lighting equipment list by substituting
similar style fixtures on an as needed basis due to but not limited to the
following circumstances:
a. The
manufacturer of an approved lighting equipment no longer supports that fixture,
or
b.
The increased cost of the approved lighting
equipment, or
c.
New lighting technologies
The policy will be used in conjunction with the Roadway Lighting Prioritization Database
(RLPD) in determining which right-of-way will be illuminated. The RLPD
(Document 2) was prepared as part of the Right-of-Way Lighting Policy.
It does not form part of the policy but will be used
by Public Works and Services staff as a guide in deciding upgrades to roadway
lighting under the policy. The RLPD
uses a priority ranking approach where roadways are weighted based on specific
characteristics such as:
a.
Road classification,
b.
Average annual daily
traffic,
c.
Presence of schools,
community centres, libraries,
d.
Bus Route, and
e.
Emergency Route.
The final score of each roadway is then ranked in
descending order with the highest scoring roadway given the greatest priority for
the installation of roadway lighting. The RLPD will be revised on a periodic
basis as street lighting is installed by the Public Works and Services
Department. Although a roadway may have priority for street lighting, it still
has to meet lighting warrants before any lighting is installed. The lighting warrants in the policy are
referenced from the Guide to the Design
of Roadway Lighting by the Transportation Association of Canada. The
process under which a roadway is considered for street lighting is illustrated
in the process flow chart shown in Document 4.
Financial
In order to assess the financial impacts of the draft Right-of-Way Lighting Policy, a financial review of the costs associated with the various options contained therein is necessary. Three areas of the policy have therefore been examined as follows:
The
analyses that were conducted are based on a 30-year life cycle and a
one-kilometer section of road. City
standard roadway cross-sections and the equipment proposed in the Policy were
used for all calculations. For
comparison purposes, only a sample of the luminaires was included. All life cycle costs are in 2006 dollars.
Half-IES vs. Full IES
The use of half-IES light levels is recommended in the draft policy for local roads in new residential, employment, and mixed used centre areas. This approach follows the former City of Ottawa practice. The comparison of costs for this alternative involved carrying out lighting calculations using a City standard local road cross-section and then determining the required pole spacing that would satisfy both the half and full IESNA lighting criteria. The calculations were performed using High Pressure Sodium lamps and four different “standard” luminaires recommended for use in the new draft Policy. The luminaire types and cost comparison results are tabulated below.

Regardless of the type of luminaire used, the half-IES design criteria results in fewer poles than a full-IES design and hence an initial construction savings. These savings are further increased when both the reduced energy consumption and maintenance operations are factored in. Overall, the present value savings per kilometer of road range from $18,000/km to $38,000/km. Assuming an equal use of all luminaires used in the analysis, the average savings are $24,000/km. Energy and maintenance savings alone average approximately $10,000/km.
Decorative Lighting vs. Standard Lighting
Equipment in Special Areas
The comparison of decorative and standard lighting equipment installations was achieved by preparing typical designs for various City standard roadway classifications using both a decorative luminaire/pole assembly with metal halide lamp compared with a standard pole/flat glass cobrahead luminaire with a high pressure sodium lamp. For the case of arterial roads, three separate comparisons to standard equipment were prepared; mid-height poles, tall-height poles, and tall-height poles with a short-height pole interspaced between each pair of tall poles. For all other roadway classifications, the decorative option utilized the most expensive option contained in the policy (mid-height poles) in order to illustrate the maximum differential in cost that could be expected. The luminaires used for each analysis are identified beside each of their respective life cycle costs. The results are shown in the table below.

The use of decorative lighting equipment will result
in increased costs in all aspects of the lighting installation life cycle. Generally speaking, decorative lighting
equipment carries a higher material cost than standard equipment which results
in increased initial construction costs.
The increased number of poles required to satisfy the lighting criteria
translates directly to increased energy consumption and increased
maintenance. The cost premium
associated with construction, energy and maintenance of decorative lighting
equipment for the situations analysed above range from 81% to 434% or $119,000/km
to $1,325,000/km. A portion of the
premium cost is associated with the use of metal halide lamps instead of
high-pressure sodium. The costs
associated with metal halide are summarized below.
Metal Halide (MH) vs. High Pressure Sodium (HPS)
The analysis associated with metal halide lamps compared the design requirements for one typical road cross-section of each roadway classification. The equipment style in each comparison remained the same (type C luminaire), only the internal lamp type was changed. The results are summarized in the table below. The intent of this analysis is to demonstrate the potential savings that can be realized if it is decided to use HPS lamps instead of MH lamps in the Special Areas.

The use of metal halide lamps to achieve white light as compared to the yellow light produced by high pressure sodium lamps does result in an increase in costs. As can be seen from the results, the typical premium for MH is approximately 15‑21%. The higher costs are primarily attributed to the fact that metal halide lamps produce less light output (approximately 25% less) than high pressure sodium lamps of comparable wattage. Furthermore, metal halide lamps have a shorter life span (approximately 25% less) than high-pressure sodium lamps and are about twice as expensive to purchase.
The
policy currently identifies that metal halide lamps will be utilized for all
decorative lighting equipment used in special areas. Given the premium cost associated with the decorative lighting
equipment, the metal halide lamps may be considered as optional, i.e. the
decorative lighting equipment may be installed with high pressure sodium
lamps. In the event that it is decided
to use high pressure sodium lamps with the decorative lighting equipment,
savings of $21,000 to $69,000 per km of road can be expected over the life
cycle of the installation (30 years).
Financial Implications
Summary
Having
completed the financial life cycle analyses above, it is necessary to estimate
financial impacts by consolidating the costs/benefits and relating them to the
expected/estimated roadway lighting projects for each type of roadway.
Half IES Lighting
Levels
For
roads built between August 2002 and April 2007 in urban
areas outside the Greenbelt, the total length of new public
local roads built was 151.1 km. Based
on this historical data and for the purpose of analysis, it has been assumed
that the City will inherit from developers approximately 30 km of new local
roads per year. Although the City will
not incur construction costs for these new roads, it will be responsible for
the energy consumption and maintenance of the lighting on these roads. The adoption of half IES lighting criteria
will apply to the 30km of new local roads and therefore the City will realize a
present day savings of approximately $300,000 for each 30km of road ($10,000
per year over the 30 year life cycle) or, $333 per year for one kilometre of
road.
Decorative
Lighting
With respect to decorative lighting, a summary has been prepared which indicates the total lengths of existing roads that qualify for decorative lighting under the policy and their respective additional construction, energy, and maintenance costs as compared to standard lighting. Note that the table below does not include the length of local roads located in the various Heritage Conservation Districts however certain road segments listed pass through these areas. Also, those roads, which already have decorative lighting, are not factored into the cost summary since they will be reconstructed at normal lifecycle replacement time subject to budget approval and the existing decorative lighting will be replaced at that time. It is important to note that costs will be incurred for the replacement of existing decorative lighting. The remaining roads i.e. those without existing decorative lighting are included. For the purpose of the analysis each of the arterial roads have been assumed to receive one of the three different styles of decorative lighting as discussed above. To complete the forecasting estimate of overall costs, other roads have been assigned one of the possible lighting scenarios appropriate for the road type as set out in the draft Policy. The following table summarizes the present value life cycle (30 years) costs for decorative lighting:

The total cost of new decorative lighting construction will be spread out over many years as roads are reconstructed or undergo major lifecycle re-lighting, subject to Council approval of annual capital budgets. The following table summarizes some average road construction costs and separates out average costs for lighting using standard lighting and using decorative lighting. The purpose of the table is to illustrate approximate increases from standard lighting to decorative lighting relative to the total cost of road construction. The sample road costs shown represent the general costs associated with the above-ground components of new road construction including standard lighting, landscaping, pavement, sidewalks, curb and gutter. They do not include utility relocations that may be required as a result of construction nor any underground utilities. These additional works would increase the general costs shown and would have the effect of correspondingly reducing the percentage of lighting costs.

In summary, the inclusion of decorative lighting in road construction projects in Special Areas based on the examples used above requires approximately 4.5% - 10.2% increase in overall construction costs compared to standard lighting. The average increase in road construction cost per kilometre for decorative versus standard lighting based on the four road types illustrated above is $167,000. This average cost will increase or decrease year-to-year depending on the road type reconstructed and the lighting option selected.
Over the past five years approximately 57.5 kms
of City Roadway underwent major reconstruction. Approximately 13 kms (2.5 kms per year) of these roads were
located within the “special areas” as identified in the policy. The average
increase in construction cost for decorative compared to standard lighting
equipment is approximately $167,000 per kilometre. Using this average cost, and assuming that similar lengths of
road are reconstructed in future years as were reconstructed in the last few years, it is possible to
forecast basic future annual increase in capital costs for decorative lighting
in Special Areas. The approximate
annual cost increase would be $417,500
($167,000 per/km x 2.5kms per year).
Note that
this amount is in addition to the budget normally required to pay for standard
street lighting installations. Staff will review the ability to partially
offset the capital cost of installing decorative street lighting through
development charges at the next update to the City’s Development Charges
By-law.
Energy and Maintenance
Costs
An increase in energy and maintenance costs will be experienced with each new installation and hence a mechanism is required to allocate the additional funds required to properly maintain the new decorative lighting. Therefore, for every kilometre of decorative lighting approved for installation at budget time for new roads, an annual budget allocation to cover on-going total increased energy and maintenance costs of $12,100 /km/year should also be approved. For roads with existing standard lighting that are reconstructed with decorative lighting, the increased energy and maintenance budget over that required for standard lighting is $7,075/km/year. This amount represents an estimate of the average total energy and maintenance cost for one kilometer of decorative lighting when each type of road cross section is combined. It is further expected that the City’s maintenance contractor may increase the equipment stocking costs charged to the City as new decorative lighting equipment is required to be maintained in their inventory. These cost increases are not known at this time.
Over the past five–year period, approximately one
kilometer per year of new road that would qualify for decorative lighting was
constructed in Special Areas at developer cost. If this average of one kilometer per year continues in the
future, an average annual increase in the budget for energy and maintenance of
$12,100 would be required. For the estimated 2.5 kms per
year of reconstructed road (discussed above), an on-going annual maintenance
and energy budget increase of $17,700 ($7,075 x 2.5kms) would also be required. Note that these amounts are in
addition to the usual energy and maintenance budget allocation required for
standard street lighting.
The final capital, energy and maintenance cost increases will be refined based on required revisions to the draft Right-of-Way Lighting Policy and will be included in the future report to Committee. The final cost increase estimates would also need to be added to the Long Range Financial Plan.
Based on the preliminary average costing and assumed lighting designs discussed above, the required additional (i.e. over and above standard street lighting costs) operating and capital costs for 2008 if the Policy is approved as drafted are summarized below. Note that these costs cannot be finalized until the actual road construction / reconstruction program for 2008 is finalized and the actual lighting designs for the roadway are selected.
· The total budget required to reconstruct 2.5kms of roadway based on the average costs shown is $5,566,875 of which an average of $254,375 (4.5%) would be the cost for standard street lighting. The additional average capital budget to pay for the cost premium associated with installing decorative lighting on 2.5 kms reconstructed roadway in Special Areas is $417,500 (7.5%) which would increase the total average lighting cost to $671,875 (12.1%).
· Additional average operating (energy and maintenance) budget to pay for cost premium associated with installing decorative lighting on 2.5kms reconstructed roadway in Special Areas: $17,700.
· Additional average operating (energy and maintenance) budget to pay for cost premium associated with installing decorative lighting on 1.0km of newly constructed roadway in Special Areas: $12,100.
· Therefore, the net average 2008 budget increase would be: $417,500 + $17,700 + $12,100 = $447,300 / rounded up to $500,000.
Comparison with
Lighting Ordinances and Policies of Other Municipalities
As part of the development of the Right-of-Way Lighting Policy, the polices/practices of other municipalities were reviewed. The lighting policies of North Vancouver, Calgary, Edmonton, Toronto, Hamilton, Kitchener, Burlington, Windsor, Vaughan, Mississauga, Oakville, Oshawa, Kingston and Mississippi Mills were reviewed and/or discussed with municipal staff. All the municipalities that were investigated recognize the Illuminating Engineering Society of North America (IESNA) or the Transportation Association of Canada (TAC) as authorities for defining the lighting criteria. The primary differences between the other municipalities’ practices and Ottawa’s relate to when and where decorative equipment is used. Although some municipalities have practices in place relating to the use of decorative equipment on a case-by-case basis, Ottawa’s Policy is unique in how decorative lighting equipment is required to be used in specified “Special Areas” and that the Special Areas match Official Plan land use designations. These land use designations include for example the Central Area, Mixed-Use Centres / Town Centres, and Traditional Mainstreets.
Existing Lighting
Policies Reaffirmed
The Right-of-Way Lighting Policy incorporated parts
of the existing Residential Street
Lighting Policy, 2001 including;
Future Lighting Zone
Study
The proposed Right-of-Way Lighting Policy only deals
with street and sidewalk lighting located within the public rights-of-way. At the time the terms of reference for the
Right-of-Way Lighting Policy were approved by Council in 2006, staff were asked
to provide in the interim report to Committee the cost to undertake a
subsequent lighting study looking at ways to regulate and provide guidelines
for maximum light levels for lighting on private land adjacent to the public
right-of-way. For example, private lighting of commercial properties (e.g. car
dealerships) can adversely affect adjacent public right-of-way users, more so
the drivers than the pedestrians, as they have to adapt to the increased light
levels adjacent to the roadway. Unregulated private lighting contributes to
light pollution, e.g., poorly aimed floodlighting for signage or building
frontage that in turn wastes energy and increases green house gas
emissions. At this preliminary stage it
has been assumed that the Lighting Zone Study would apply to commercially-zoned
land and to high-density residential zones.
The locations and applicable zone types would be refined through
development of the terms of reference and further through the actual study. The study for lighting properties located off the
public right-of-way would look at:
With direction from Committee, the terms of reference
for this future study will be finalized and the cost included for consideration
in the 2008 budget discussions. The
study is estimated at this time to cost approximately $50,000.

CONSULTATION DETAILS DOCUMENT 3
CONSULTATION PROCESS AND NOTIFICATION
A
Strategic Policy Directions Paper was prepared and circulated to City
departments, Advisory Committees, technical agencies, stakeholder groups and to
Council members in June 2006. The
document summarized for discussion purposes possible approaches to roadway and sidewalk
lighting citywide. The purpose of the
circulation was to receive input early in the project to guide subsequent
preparation of a first policy draft.
Presentations were made to six Advisory Committees
at their request (Accessibility, Seniors, Rural Issues, Pedestrian and Transit,
Roads and Cycling and Forests and Greenspace).
Oral comments were received from Advisory Committees as follows:
Comment: Inquired if
the policy will address trimming of trees to accommodate street lighting?
Response: The draft policy will include that tree
trimming will not be undertaken to accommodate street lighting except under
special circumstances and provided that tree planting was carried out in
coordination with streetlight placement as part of the design of the street.
Comment: Concerned about the effect of light on trees.
Response: Staff agreed to look into this issue and to address it as may be needed in preparing the draft policy.
Comment: Are lawn
lamps to be used in the new policy to light streets?
Response: Lawn lamps are not proposed to be used for
street lighting. Existing lawn lamps
located in the right-of-way in two Kanata communities are planned to be phased
out over time.
Comment: Inquired if
LED lighting technology was considered for the new policy.
Response: LED was considered but not adopted at this
time since it is at present an emerging technology and is not at a point where
it can be used cost-effectively on a citywide basis.
Comment: Asked about
annual energy cost for street lighting and if the new policy would result in
energy cost increases.
Response: The annual energy cost for
the City is approximately $4 million. Metal halide (white) light is proposed
for use in “Special Areas”. This style
of lighting has a slightly higher energy cost but that increase is expected to
be partially offset by savings realized through other lighting efficiencies
proposed in the policy. Costs will be
presented to Committee for consideration in an interim report later in the
project.
c) Pedestrian and Transit
Advisory Committee
Comment: Is hydro
burial part of this policy?
Response: Consideration of Hydro burial is part of a related “Street Design” policy project being
undertaken by other staff.
Comment: Asked who
is responsible for streetlight maintenance in the City.
Response: Streetlight maintenance is carried out by
contract between the City (Public Works and Services) and electrical
contractors Black and MacDonald.
Comment: Inquired if
solar lighting technology was considered for the new policy.
Response: Solar was considered but not adopted at this
time since it is at present unproven for use on a citywide basis.
d) Rural Issues Advisory Committee
Comment: Thought
that public consultation approach was good but asked if more than one rural
area public open house meetings could be held.
Response: Project budget constraints prevent staff
from undertaking additional open house meetings but it was agreed to email
notice of the rural public open house meeting to all registered rural community
organizations to ensure greater awareness of the proposed policy.
e) Seniors Advisory Committee
Comment: Inquired as
to whether or not night time safety for seniors was improved through use of
proposed metal halide (white) light source in “Special Areas”.
Response: It is accepted in lighting design that there
is improved colour recognition (clothing, vehicles, buildings, landscape,
etc.) in white compared to yellow (high
pressure sodium) light and therefore may be a perceived increase in level of
safety and security.
Comment: Inquired if
LED lighting technology was considered for the new policy.
Response: LED was considered but not adopted at this
time since it is at present an emerging technology and is not at a point where
it can be used cost effectively on a citywide basis.
f) Accessibility Advisory Committee
Comment: Can the
policy address lighting of street name signs?
Response: Street sign lighting is not part of the
scope of the project as approved by Council.
This approach would also be costly for the City to operate and
maintain. Not needed since high
reflective sheeting is used for all street signs.
Comment: Are
Transitways included in the lighting policy?
Response: Transitways are excluded from the policy but
are to be lit as may be required based on site-specific review with appropriate
City departments.
Comment: Regarding
the two proposed light levels for sidewalks (higher for sidewalks along
arterials and lower for sidewalks along other streets), are the IES standards
being followed?
Response: The first draft of the policy adopted the
sidewalk levels of the 2001 Residential Street Lighting Policy that are lower
than the current ANSI/IESNA recommendations.
Upon further review during the technical analysis, it has been
determined that certain sidewalk design criteria can be increased to satisfy
ANSI/IESNA recommendations for Major Collector (now 5 Lux as opposed to 2 Lux),
Collector (now 3 Lux as opposed to 2 Lux) and Local (unchanged at 2 Lux). The
design level for sidewalks on arterial roads has also been increased in the new
policy from 5 Lux to 10 Lux .
This
arterial road sidewalk level however does not satisfy the 20 Lux criteria
recommended in ANSI/IESNA since the roadways would need to be correspondingly
“over lit” to achieve the brighter sidewalk standard. It is worth noting that 10 Lux is an ANSI/IESNA recommendation
for sidewalks adjacent to arterial roads but not directly beside
the traveled lanes.
Comments were received from stakeholder groups as follows:
g) Royal Astronomical Society of Canada (RASC)
Comment: RASC would like City to adopt Small Target Visibility (STV) method of undertaking lighting calculations.
Response: Not recommended since STV is at present an unproven street lighting calculation method.
Comment: RASC wants City to use full cut off luminaires located at pole spacing used for semi-cut-off fixtures and thereby accept less light in-between fixtures in order to achieve further reductions in energy cost, light levels, glare and light trespass. RASC suggests that the reduction of glare provided by full cut-off luminaires will compensate for the possibility of reduced visibility caused by lower light levels in-between fixtures.
Response: Not recommended since in addition to reduced levels, the uniformity may become sub-standard. Staff agreed that use of full cut-off luminaires on growth-area residential, employment, and mixed-use centre area local streets with spacing in accordance with IES calculations could be introduced into the draft policy. (These areas are also subject to the proposed 1/2 IES light level.) Glare criteria in accordance with IES criteria has been introduced as part of the policy.
Comment: RASC agrees with the need to use semi-cut-off luminaires for rural area marker lighting but would like the City to use lower wattage lamps.
Response: Staff agreed to review by area application and include lower maximum wattage lamps where possible in the rural area. Reduction to 100 watts from the current standard of 150 watts is proposed for all rural area marker lights in the draft policy.
Comment: RASC would like City to review use of 1/2 IES illumination on collector roads and less than 1/2 IES (1/3 or 1/4) on local roads in residential areas.
Response: Not recommended given
higher traffic volumes and increased pedestrian traffic on collector roads. 1/2
IES light level is proposed given its use as a standard lighting approach in
former Ottawa. Staff and consultants
are unaware of any municipality where less than 1/2 IES is being used except
where marker lighting or no lighting is the adopted municipal standard.
Comment: RASC wants City to use programmable photo controllers to turn off streetlights in specified areas after normal business hours – at for example 2am or 3am.
Response: Not recommended given that the cost of installing and maintaining such devices may be greater than cost savings realized through energy reduction. In addition, evening shift workers and others on City streets during late evening hours should enjoy the same level of perceived safety afforded to all citizens.
h) Ottawa-Carleton Home Builders Association
Comment: I have been
asked to comment on the proposed policy as presented in the power point
presentation that you distributed to OCHBA.
We are encouraged by the approach taken of identifying different
development styles, road categories and options for both luminaries and poles
and differing lighting levels for those categories. We are obviously very interested in pursuing these standards with
the City. Unfortunately, as you
explained, we do not know the impact of the new lighting levels and, therefore,
it is difficult to provide any specific comments at this time.
We would appreciate being included in any
information packages that become available as the policy develops as well as
the opportunity to comment along the way.
Response: Draft Right-of-Way Lighting policy was
circulated to the OCHBA in March 2007 for its consideration and comments.
2. General Comments From The Public
The following general comments were received prior to public release of the first draft of the Right-of-Way Lighting Policy:
a)
Comment:
You made a presentation June 20th for RIAC with regard to subject
above. Because you are asking for input, as an individual, I have taken
the liberty to post to you a copy of an article in last week's Almonte Gazette
entitled "Town praised for its decision to preserve night sky
viewing." Perhaps you have already had the opportunity to read this article
or one similar. I have spoken to Mr. Forbes Symon about his
"responsible lighting" policy and as a nearby resident who has
participated in area astronomy events in the past, I have followed the leading
attitude Mississippi Mills has developed with regard to lighting in a mainly
rural area. Mr. Symon recently received an award from the RASC given
"in recognition of Mississippi Mills being the first municipality in
Canada with policies in place that preserve night sky observing as well as a
bylaw that regulates lighting issues for all site plan agreements."
Symon later says "When discussing the Official Plan, one of the questions
we asked was 'what is rural character?'
One thing that struck us was how you can go into your backyard, look up
into the sky and see the stars. That is something that is distinctly
rural.'" As well "The reason we have been so successful with
this is because aside from the whole night sky thing, it also saves money,
reduces energy consumption and stops light pollution onto other people's properties,
which ties in with property rights."
In the case you might want to speak to Mr. Symon or add him to
your circulation list (and he is always glad to share his views) his number is
256-2064 X 259.
Hopefully the work you are engaging on will save us money and
preserve the beauty that is a brilliant rural evening sky. Thank you
again for your initial presentation and questions answered.
Response:
The Lighting Policy for Mississippi Mills
covers public road rights-of-way as well as private property. It requires the
use of full cut-off luminaires (0% up-light emanating from the light fixture)
for all lighting applications. Although not as comprehensive as the Ottawa
Right-of-Way Lighting Policy, there is one similarity relating to reduced
lighting levels. The Town’s by-law
identifies ranges of lighting levels for each classification of road (major,
collector and local). These levels
range from 66% of IES recommendations at the lower end up to 94% of IES
recommendations at the higher end. The proposed Right-of-Way Lighting Policy for the City applies only to
public rights-of-way. The draft policy
for the City does propose to require use of full cut-off luminaires for all new
local roads in residential and employment areas and also requires that full cut-off
lighting be considered for all other roadway lighting designs. Maximum wattage for marker lighting is
also100 watts (reduced from 150w).
b) Comment:
In section 2.4 of the policy entitled “illumination equipment”, several
different types of equipment were listed within the inventory of lighting
currently used by the city of Ottawa.
As your policy will aim to reduce the variety of lighting equipment
within the city, this is a perfect opportunity to focus investments in
equipment that can potentially improve efficiency and reduce detrimental
effects on bird populations.
Many species of birds migrate at night, including numerous species of
warblers, thrushes, and wrens (Graber 1968).
Collision with man-made structures is a problem that is continent-wide
for migrating birds (Ogden 1996).
Nocturnal migrants have demonstrated a form of attraction to light, with
lighthouses as the first man-made structures to attract birds (Reed 1985). A scientist by the name of Richard Graber
(1968) described birds’ reluctance to leave a lighted area and to fly out into
the dark upon entering. This reluctance
is currently noted as a hazard today by a concerned group of residents who
collect dead and injured birds within the city of Toronto.
The
birds that they collect for rehabilitation have become trapped within the city
itself, upon entrance (Ogden 1996). A
study performed by Reed demonstrated that light shielding decreased the
attraction of endangered seabirds in Hawaii.
He found that fledgling birds were attracted more to light sources
themselves, rather than the areas they illuminated (Reed 1985). This indicates that the effectiveness of
lighting for human purposes need not be lessened in order to decrease avian
attraction, or light pollution in general for that matter.
Cut-off
lighting which reflects additional light downward would increase the efficiency
of lighting. Meanwhile shielding of
low-level lighting such as the potential streetlights being considered, may
reduce the attraction of migrant birds to light shining upwards from Ottawa
(Ogden 1996). This could potentially
increase the survival rate of these birds by avoiding their entrapment within
the city.
Two
criteria for the lighting policy currently under consideration could be met
with cutoff lighting: cost effectiveness, and abatement of light pollution. As
a result, we could save money and maintain our continued enjoyment of the night
skies while additionally mitigating the effects that a large city like Ottawa
has on night migrants.
Response:
The draft policy requires use of full
cut-off luminaires for all new urban area residential and employment area local
streets. The policy also directs that
full cut-off luminaires should be considered for use first in lighting design
for all other roads (with semi cut-off being the only other option on an as
needed basis). Light levels are also
proposed to be reduced in urban residential and employment areas as well as on
marker lights in rural areas. The
policy also requires special consideration of lighting design for all roads in
proximity to Urban Natural Features areas.
c) Comment:
We
have a committee working on Beach Protocol with respect to the waterfront
access lanes (rights of way) in Constance Bay. As part of our scope we are
examining whether or not the community wants improvements to the access
lanes. Perhaps further down the road, lighting could be considered a
possible improvement, depending the committee's finding and recommendations.
Would this policy apply to the waterfront (rights of way) access lanes?
Response:
The intent in early
drafts of the policy was that marker lighting would only be considered for
installation at the intersection of two opened public roads (public
rights-of-way that have constructed roadways within them). A new subsection dealing with marker
lighting has been added to the draft policy to clarify this issue. Specific site review is required to
determine if the beach access roads referred to in this comment would qualify
for marker lighting.
In March 2007 City departments, technical agencies and stakeholder
groups were asked to review and comment on a preliminary draft of the policy
prior to public release of a revised draft at the April 10th and 11th
2007 public open house meetings. The
following comments were received:
a) Royal Astronomical Society of Canada (RASC)
Comment:
1.2 Intent
We would like to see a specific reference to the reduction of light
pollution
Response:
Revision made.
Comment:
1.3 Purpose of Lighting
Item “iv” in last list of section - amend to ...resulting increased
cost for electricity, and greenhouse gas emissions.
Response:
Revision made.
Comment:
2.1 Lighting Design Calculations
The use of a 0.7 maintenance factor will result in illumination of 40%
above the recommended values. We ask that it be increased to reflect the
degradation of the light output over the life of the bulb. The flat glass of
the FCO luminaires does not suffer the same dirt build up as the drop glass
lenses. As long as the sealing gaskets for the fixtures are serviceable,
insects should not be able to enter the enclosure.
Response:
The 0.7 factor is the standard used by
many authorities responsible for roadway lighting. It is derived by combining the losses associated with not only
dirt but also lamp lumen depreciation in order to account for the effect of an
aging lamp. Sealed luminaires are
susceptible to interior dirt depreciation regardless of the fact that they are
sealed with a gasket. No known evidence
to support less exterior dirt build up on full cut-off luminaires as compared
to semi-cut-off luminaires.
Comment:
2.2 Required Average Roadway Lighting Levels
The maximum glare ratio does not factor in the higher sensitivity to
our aging population or the scratches and pits of an automotive windshield.
Although this is virtually impossible to accurately characterize - they are
important factors and some correction should be made. We can suggest at least a
factor correction that would lower the limiting glare from 0.3 to 0.15
(specified later in the document) until research can suggested a more
statistically determined number.
Response:
The 0.3 factor is based on IES
recommended values. The suggestion to
reduce it from 0.3 to 0.15 may likely necessitate an increase in the Pavement
Luminance lighting levels since the Disability glare is the ratio of Maximum
Veiling Luminance (LV) to Average Pavement Luminance (LP).
Comment:
Table 2.1 - Under Rural Area - Arterial. We suggest lowering the
average luminance from 0.8 to 0.6. The roads are typically much narrower and it
is in keeping with the rural character of small towns and villages. We do not
think the Rural Collectors should be lighted to the same level as the Urban
Collectors. Similarly, the Rural Local streets should be lighted to lower
levels than the Urban Local streets.
In footnote #3, we feel the reconstructed roadways should not be
re-lighted to the original levels. They should be lighted to the new levels.
Response:
Footnote #3 - The policy does not
require that reconstructed roadways be lit to new (lower) lighting levels. If the Policy is approved as presently
drafted, residents on streets that have marker street lighting or that have
full street lighting for example will not have lighting changes made to their
communities. The reason for this is
that citizens presumably were aware of and preferred the style of lighting on
their chosen street when they selected to live in the community. Also, the cost of installing full street
lighting with lower light levels on streets that presently have marker lighting
or changing to lower light levels (which may require new pole spacing) on
streets that have existing full lighting would be considerable. Rural collector and rural local roads will
only receive marker lighting unless the roads are classified as village
mainstreets under a future public consultation process
Comment:
Table 2.2
This table should be corrected for the suggested changes to Table 2.1.
Response:
No changes required.
Comment:
2.4 Sidewalks
We
suggest that waist level fixtures be used to “mark” pedestrian walkways
(bollards?). These are used in some parks in Toronto (Willowdale Park in North
York). Although some see damage by vandals, so do the 3 m high luminaires.
Response:
Bollard (waist level) lighting is
highly susceptible to vandalism. The
minimum height for “through-block pedestrian walkways” in the policy is 4.5
metres which is high enough above the ground to avoid most forms of vandalism.
Comment:
2.5 Underpass, Tunnel, etc.
The
light from these fixtures reflects off the concrete walls resulting in more
light that scatters onto the road surface. We feel the illumination levels can
be reduced because of this effect unless the calculation accounts for this
effect. (One feels trapped by the walls of light). Also, these luminaires are
well sheltered from the weather. So the maintenance factor should be increased
to only account for bulb degradation.
Response:
Underpass illumination does not
consider reflections from the concrete surfaces since the light output is
typically directed away from these surfaces and therefore the reflected light,
if any, is minimal. Tunnel illumination
will be dealt with on a project by project basis. In these cases, tunnel illumination design will consider the wall
reflectance since these walls are typically of a highly reflective material and
the luminaires, when ceiling mounted, direct the light both downward and
towards the walls.
Underpass luminaires accumulate more
dirt as compared to typical street light fixtures because they are sheltered
from the weather elements such as wind and rain which aids in the natural
cleaning of the fixture. Also because
they are in a semi-enclosed environment and mounted at almost half the height
of typical fixtures they are more susceptible to moisture and dirt spray from
passing vehicles, especially in the winter months, thereby requiring more
frequent cleaning. The current
maintenance factor of 0.7 takes into account the regular scheduled maintenance
of underpass lighting fixtures by the City.
Increasing the factor would result in increased maintenance costs as the
City would have to clean the fixtures more often to maintain the light levels
within the underpass.
Comment:
3.2 “Special Areas”
If
lantern style is preferred by businesses and residence it should be made
explicitly clear to them that the quality of lighting (referring to
illumination, glare and light trespass) will be inferior to that of the FCO
luminaires. Further, in order to illuminate
the roadway to the required levels will result in much brighter bulbs and
electrical usage. Also, they should be made aware of the higher cost for these
fixtures.
Response:
The draft policy has both semi and
full (FCO) cut-off style lantern style luminaires. The project consultants are to ensure that efficient, high
quality lighting was recommended and have evaluated all Special Area
equipment. The wattage for lantern
fixtures has been set at a range of 70 to150 watts (in the low range) to reduce
potential for light glare. With lower wattage
lights, (decorative) poles will be placed more frequently along the
street. This adds to the urban design
quality of the street and helps to improve lighting uniformity. The additional cost of lighting with
decorative lighting equipment is discussed in the body of the staff report.
Also the lantern fixtures are only
being used on Collectors and Local roadways where the road cross-section is
small as compared to an Arterial roadway.
For these smaller road cross-sections the lighting performance of the
lantern fixtures are actually comparable to the FCO cobra head fixtures in
terms of pole spacing and lamp wattage.
Comment:
3.3.1 Rural Local Roads / 3.3.2 Existing Unlit Urban
Local Roads
“Super Mailbox” locations
should be lighted with FCO fixtures. There will be sufficient vertical surfaces
to scatter light to assist in “locating” the boxes and provide light to access
the boxes.
Marker lighting should be with the lowest practical wattage (70 watt
HPS or lower wattage LPS).
Lighting sharp horizontal curves should not be used. When
retro-reflective markers only mark curves, on-coming traffic can be seen as
motorists enter the curve. If the curve is illuminated by pole mounted
fixtures, the lights from on-coming traffic cannot be seen. We suggest that it
is safer to not light these curves.
Response:
Revision made – marker lights at super
mailbox locations will be full cut-off style.
The standard marker lighting wattage
presently in Ottawa and in most other Canadian municipalities is 150
watts. The policy proposes to reduce
the wattage for all marker lights by one-third to 100 watts.
Staff is not of the opinion that
lighting the curves will result in a negative impact on safety since studies
have shown that lighting reduces night time accidents by 30%. Therefore, the
draft policy directs that unlit roadway curves that do not meet the geometric
design standards of the Canadian Roads and Streets design manual would receive
partial lighting subject to site specific review and available funding.
Comment:
3.3.2.1 Existing Urban
Local Roads with Marker Lighting
We feel existing marker lighting should be reduced to70 watt during
reconstruction.
Response:
The standard marker lighting wattage
presently in Ottawa and in most other Canadian municipalities is 150 watts. The
policy proposes to reduce the maximum wattage for all marker lights by
one-third to 100 watts. It is recommended not to reduce this further as a
standard.
Comment:
3.3.4 Lighting Strategy
As the city grows outward, boundaries between “rural” and “urban” areas
will continually change. This is not a slow wave of development. Rather, we see
housing developments being built in “very rural” locations as farms are turned
into homes and business areas. As they are built, these areas can be deemed to
be “urban” and the proposed increase in illumination will dramatically increase
the sky glow over our members “dark observing sites”. We would like to see the
illumination levels remain at rural levels until the space between these
enclaves has been in-filled.
Response:
Urban style housing development only
occurs on approved urban area land as designated in the Official Plan. This land is often used for agriculture
until development occurs. Leaving new
streets in new urban area subdivision developments at rural lighting levels (no
lighting) is not recommended as an interim measure prior to full lighting. Light levels for growth area development is
already proposed to be reduced compared to the existing standard. The draft policy sets urban residential and
employment area local street lighting levels at one-half the IESNA recommended
lighting levels. Marker lighting is
also proposed to be the new standard for rural estate subdivisions. Marker light wattage is proposed to be
reduced from 150 to 100 watts.
Comment:
3.3.7 Pedestrian Walkways
We suggest that low-level bollards be used to mark and illuminated the
ground along these pathways. Since there is no motor traffic, they do not have
to be illuminated to the level of sidewalks along streets.
Response:
Bollard (waist level) lighting is
highly susceptible to vandalism. The
minimum height for “through-block pedestrian walkways” in the policy is 4.5
metres that is high enough above the ground to avoid most forms of vandalism.
Comment:
4.1 Background
Explicitly state the option for bi-level lighting.
Response:
Bi-level lighting (dims at off-peak
periods) requires installation of special lighting ballasts in addition to the
dimming equipment on every luminaire.
Lights also become susceptible to premature failure when they are dimmed
which may increase maintenance costs. This approach has not been proven as
being cost-effective and is still a relatively new technology. On streets that are lit, the same level of
safety should be provided to citizens using roads and sidewalks at all hours of
the nighttime.
Comment:
4.4 “Special Areas” - The phrase “areas that may also use”
suggests that two systems of lighting can be used. This is both expensive and
adds visual clutter along the street. The cost of the second system (capital
and maintenance) should be borne entirely by the residence.
Response:
The intent was not to permit two lighting systems along any right-of-way. The wording in the draft policy has been clarified.
Comment:
4.4.1 Lighting Strategy for “Special Areas”
We feel the opening statement “Special lighting shall be used ...”
should be relaxed to read, “Special lighting MAY be used ...”. This would avoid
the automatic use of non-FCO fixtures where people of the areas may prefer FCO
fixtures (see earlier suggestion in paragraph 3.2 “Special Areas”).
Similarly in the second paragraph, we would prefer “The first option
MAY be installed ...”
4.4.2
Special Lighting Equipment
In the second paragraph we prefer, “Special lighting MAY be ...”.
Response:
Use of the word shall is needed so
that decorative equipment is used in Special Areas. It does not mean that non-full-cut-off fixtures are automatically
used in these areas. Non-cut-off fixtures are also not part of the approved lighting
equipment for the City.
Comment:
Table 4.1
We discussed this table during our meeting. We understand some entries
will be reviewed and revised (400 watt levels). We note that the higher
wattages are restricted to FCO luminaires and lower wattages are used in the
lantern type. We also note that the higher wattage lanterns use higher wattages
than the clear glass lanterns.
I question the entry that places lantern-type fixtures under the semi
cut-off column. From my practical experience, I very much doubt that only 2.5%
of the light from these fixtures shine above the horizon. I suggest it is more
like 20%. Further, with a frosted glass it is probably higher than 20%
“up-light”. Similarly for the Acorn-, Hat- and Cage-style fixtures.
We understand our proposed reduction in limiting glare from 0.3 to 0.15
(papa. 2.2) will place constraints on the selection of lantern-type fixtures.
However, these types of fixtures, for all their daytime and twilight
aesthetics, are very distracting during the night for senior citizens and
drivers behind windshields.
Response:
The semi-cut-off designation is based
on independent photometric testing as per IESNA luminaire designations (note:
semi-cutoff is 5% and cutoff is 2.5%
uplight). 400 watts are still to be
used in “All Other Areas” and it has been deleted from “Special Areas”.
Comment:
4.5.3 Roadway Lighting Equipment Context
We are concerned that lantern-style fixtures will require very high
wattage to illuminate the roadway to the specified levels. This will result in
severe glare, light trespass. The public MUST be made aware of this when these
fixtures during open (public) meetings.
The images in this section show lantern fixtures used in residential neighbourhoods and during daylight hours. By using promotional images in the document, they are displayed in an “attractive way”. They do not show how they look in operation at night.
Response:
The maximum lamp wattage for all low
and mid-height decorative fixtures in the policy has been set at lower than the
manufacturers permissible levels to reduce glare. In addition, any semi-cut-off decorative fixture has frosted
glass to further diffuse the light and reduce glare. Light trespass will not be an issue with use of semi-cut-off and
full cut-off luminaires.
The intent of showing pictures of
lighting equipment in daylight hours is to clearly show the intended equipment
style (design) to assist in selection for future lighting designs. It is difficult to accurately demonstrate
the appearance of illuminated fixtures at night through photography since the
image can easily be manipulated to look brighter or darker through adjustments
to photo exposure time.
Comment:
Table 4.2
We understand this table is to be reviewed and revised (Rural Areas -
250 watt). We suggest lantern -type fixtures not be used in high traffic
environments due to glare and its contribution to “visual clutter”. These mask
hazards and reduce the safety of the roadway for both pedestrians and
motorists.
B1 Lantern-type fixtures should not be used into rural areas. The light
trespass has a profound impact on the natural night time environment.
Response:
Rural arterial and collectors only get
marker lighting unless they are designated as a Village Rural Mainstreets. Therefore maximum wattage will be 100 Watts.
The use of 250 watts in rural arterial and collectors have been deleted. The lantern styles proposed for use in the
policy for rural (and urban) areas are full or semi-cut off styles that will
minimize light pollution.
Comment:
Please change to, “ 150 watts to 100 watts or 70 watts ...”.
Response:
The standard marker lighting wattage
presently in Ottawa and in most other Canadian municipalities is 150 watts. The
Policy proposes to reduce the maximum wattage for all marker lights by
one-third to 100 watts. It is recommended not to reduce this further as a
standard.
Comment:
5.2 Horizontal Curves
Please include explicit reference to the use of
retro-reflectors.
Response:
Establishing
use of roadway reflective safety marking for curves is not within the scope of
this project.
b) City of Ottawa Environmental Advisory Committee
Comment:
This project falls under the Community
Design Plans and related studies 2007 item in the Development Application Review (DAR) Working Group’s 2007 work
plan.
Positive Points |
p.2: “The Policy strives to
achieve the following over time… vii. Reduce energy
consumption by lowering lighting levels in specified areas and using energy
efficient fixtures…” p.2: “the designer should
always attempt to minimize the amount of ‘over lighting’” p.18: The Policy calls for a
decrease in excessive lighting on arterial roads in the former Ottawa area
(implemented at the time of major roadway reconstruction). p.22: “”(LED) lamps were
considered for street lighting…but at this time more testing and technical
information is required…the LED should be re-visited at the time of the next
Policy update.” p.32: Full Cut-Off luminaires
produce zero “uplight”, so they will be preferred over Semi-Cut-Off in
locations other than Special Areas.
(Full Cut-Off versions aren’t always available for special lighting
styles.) p.37: Light Pollution is
Design Consideration number 1. p.37: “Street trees will not
be trimmed to accommodate the street lighting except as may be approved for
special circumstances by the Director, Traffic and Parking Operations” |
1. Would it be possible to also look into the feasibility
of a solar-powered pilot (or small scale use of solar power) as well as an LED
pilot? For example, if the technology isn't advanced enough to use large solar-powered
lights on all major streets, perhaps solar power could be considered for weaker
lights, such as the ones lighting municipal paths between two illuminated
rights of way.
Response:
The technology for both
LED and solar powered is not at the stage where they could safely and
cost-effectively be adopted for street lighting on a Citywide basis. Solar powered lights for through-block
pedestrian walkways have at present not proven to be reliable or cost-effective
in existing City applications.
2. On page 27: "LED should be re-visted at the time of
the next Policy update". Would it be possible to put in a similar
statement for solar-powered lights?
Response:
The draft policy directs that the City
review these emerging technologies and consider implementing them as they
become efficient and cost effective for citywide use.
The EAC brought forward the following
motion regarding the draft Policy:
Draft EAC Motion (March 28, 2007 version)
WHEREAS the City of Ottawa’s draft (March 12, 2007) Right of Way
Lighting Policy balances roadway safety, present technological limitations and
environmental considerations, as indicated in the attached brief;
THEREFORE BE IT RESOLVED THAT the Environmental Advisory Committee
recommend that City Council propose solar power for implementation of the Right
of Way Lighting Policy when this technology is sufficiently advanced;
BE IT FURTHER RESOLVED THAT the Environmental
Advisory Committee recommend that City Council support the new Right of Way
Lighting Policy, and that City Council direct staff to fully implement the
Policy.”
4. Public Open House Meetings – Public Release of Draft Policy
Two public open house meetings were carried out as
part of the public consultation phase of the study. Comments on the revised
draft policy were submitted as a result of the open house meetings and as a
result of public review of the open house materials and draft policy on the
project web site “ottawastreetlighting.ca”.
Notification of the public open house
meetings was carried out as follows:
Open House #1 Urban Area–April 10/07 and Open House #2 Rural Area–April 11/07
The purpose of the open house meetings was to
introduce and seek comments on the draft Right-of-Way Lighting Policy. The meetings consisted of a walk-through
open house display, which highlighted the study process and components of the
draft policy. There was a timed
PowerPoint presentation that provided an overview of the draft policy. City
staff and project team consultants were on-hand to answer questions from the
public. Twenty-two written comments
were submitted by the public and stakeholders on the draft policy released for
the open house meetings:
a) Comment:
I am an educated on-road cyclist. Desire Kanata streets to move to full
lighting rather than decorative lighting.
Desire lighting in greenbelt where safety warrants. Lawn light not be required for street or
sidewalk lighting. Condo and corner street name light signs should be replaced
– use reflective street name signs on all streets. Lights should illuminate sidewalk beside road. Special lighting on mainstreets should be
maintained. Support moving Kanata
streets to full lighting rather than limited corner lighting as is now the case
on Bellview Drive for example.
Response:
The areas
of the Katimavik and Hazeldean neighbourhoods that have lawn lamps on the
public right-of-way will be upgraded to full continuous lighting to the new
suburban standard (one-half IES light levels).
Greenbelt roads are excluded from the policy but may be lit subject to
separate review and approval with relevant agencies. Illuminated street name signs are not included in the
policy. Streetlights will be used to
light the sidewalk to minimum standard.
All street lights are part of a maintenance contract with Black and
MacDonald. No changes to existing
streets that have marker, partial or full lighting are proposed.
b) Comment:
What information do you have on the effect of light
on trees. Are there effects on tree
physiology, flowering, fruiting, budbreak, dormancy, growth?
Response:
Undertaking
detailed analysis of the effect of light on trees was not part of the scope of
the project. However staff and project
consultants carried out limited research and met with persons with expertise in
this area. There was varying opinions
on the degree of impact, the colour and intensity of light that may affect
trees and the types of trees that may be impacted. Given general consensus that there may be some impact, the draft
policy was revised to include special attention to lighting design when in
proximity to any identified Urban Natural Feature (woodlot).
c)
Comment:
Encouraging that plans proposed will maintain
infrastructure at lesser cost by streamlining options for renewal /
maintenance. Use of technology which
limits energy consumption positive. Consider next step to reduce excessive use
of energy by “Box Stores” ie. Innes Rd.
A by-law could reduce power failure such as the experience last week in
Orleans.
Response:
Staff will
discuss cost of undertaking a second lighting study dealing with private
property at the interim report stage of the right-of-way lighting project.
d) Comment:
It is important to consider street safety for
pedestrians when considering the type of lighting to be installed. White light is better than colour light for
visibility purposes. Please also consider
global warming and choose energy efficient lamps over the appearance of the
lamp.
Response:
Pedestrian
safety was a consideration in preparing the policy. All lighting equipment is energy efficient. Lighting design using proposed luminaires
was also undertaken to ensure cost effective lighting would result.
e)
Comment:
Sandy Hill needs more lighting. I hope it doesn’t
take a persons life to do it. I lived
in Centretown for 17 years and it needs more light on side streets.
Response:
Both
Centretown and Sandy Hill are located in former Ottawa and therefore the
existing lighting standards reflect that municipality’s policy of full lighting
to IESNA standards on Arterial roads and one-half IESNA standard light level on
Local and Collector roads.
f) Comment:
Wish to retain local lighting (essentially
“driveway” lights). Overall trying to
obtain “special” status for Beaverbrook.
Response:
The
direction in the draft policy for the areas of the Katimavik and Hazeldean
neighbourhoods that have lawn lamps on the public right-of-way is to upgrade
them to full continuous lighting to the new suburban standard (one-half IES
light levels) when the lawn lamps reach the end of their useful life
cycle.
g) Comment:
I support the proposal that new local roads be lit
to one-half of the IESNA recommendations.
This level has proven to be safe and sufficient in the old City of
Ottawa. I support the use of full
cut-off lighting for “All Other Areas”.
This will provide low glare, reduce light pollution, while still providing
light for roadways and sidewalks. I
support the use of decorative lights as well in Special Areas to encourage
pedestrian use in these areas.
Response:
(None
required)
h) Comment:
Glad to see that trees and lighting are components
of downtown urban design. As long as
there is enough lighting to see and be seen on main intersections where traffic
is greater (especially in winter). That
will be very important. Although
suburbs need less light – safety of pedestrians should be prime concern. Congratulations – looks reasonable but
burying overhead wires would be an attractive feature.
Response:
Tree
trimming to provide for proper intersection lighting may be undertaken under
the “special circumstances” provided for in the policy.
i) Comment:
Addition of decorative lighting for mainstreets is a
positive change to enhance mainstreets.
White light is preferable to yellow light – if high pressure sodium then
ensure maintenance to keep them from getting too yellow. Adequate lighting is important for security. The inner City is well lit at the moment –
keep it this way.
Response:
White light
(metal halide) is proposed for all “Special Areas” (mainstreets, town centres,
mixed use areas, etc.).
j)
Comment:
Light should be directed downward with none escaping
into the sky. The Glebe would be a
great place to test new types of energy efficient lighting.
Response:
All lighting equipment proposed in the
Policy directs between 95% and 100% of the light downward. Selecting locations for any possible future light
testing area was not part of the scope of this project.
k)
Comment:
The combo light standard – hydro pole concept shown in “Street Design” should also be incorporated into the “Lighting Policy”. Is a “Special Street” the same as “Special Area”? Term should be the same in both policies. Please try to reduce the amount of jargon for public consultations (ie, full cut-off luminaires) to encourage more dialogue.
Response:
Lighting equipment on existing hydro poles
is permitted in the policy. “Special
Streets” are located within “Special Areas” but will also be subject to
decorative street furniture subject to the outcome of a separate Street Design
Study scheduled to be completed later this year. Technical language was necessary to describe accurately the
proposed equipment. Annotated pictures were provided at the open house to
explain “full cut-off luminaire”.
l)
Comment:
I am very impressed by the work city staff has done on the lighting and street design policies – Bravo! I feel very strongly that all of Bank Street from Wellington to Billings Bridge should have decorative lighting as the services below the street are replaced.
Response:
Bank Street from Wellington to Queensdale is
designated in the Official Plan as either Arterial Mainstreet or Traditional
mainstreet. Much of the northerly
section already has or is under design/construction for decorative
lighting. The balance of Bank Street
(to Queensdale) will receive decorative lighting as major road reconstruction
takes place under the proposed policy.
m)
Comment:
Adequate lighting that is energy efficient is more important to me than the “style” of the fixture.
Response:
All the decorative and standard lighting
equipment selected for use in the City
is energy efficient.
n)
Comment:
And here is a URL pointing to a wide variety of bylaws in the U.S.: http://www.darksky.org/ordsregs/usamunis and here
is a moderately technical overview of a range of factors http://www.darksky.org/handbook/lc-hb-v1-14.html#lamptypes --
which by the way seems under the section on the eye and dark adaptation) seems
to support metal halide for its colour spectrum.
I just skimmed the Tucson bylaw. Do you (or your lighting
engineer colleagues) have any idea why they seem so strict with metal
halide lights? Could there be something about the colours (spectral
range)?
I was talking to you at this evening's presentation on the City's draft
policy, and asking the questions about light pollution. Here are two
references for Tucson, Arizona (I mistakenly remembered Phoenix -- right state,
wrong city): Tucson's ordinance http://www.darksky.org/resources/information-sheets/is091.html
and a short newspaper article http://www.kold.com/Global/story.asp?S=4104183 (found
with Google).
I like the idea of a per acre (or hectare) limit on light. Why
doesn't Ottawa adopt something similar? I'll try to get you and your
colleagues some more info...
Response:
Tucson, from brief review of its
lighting ordinance, appears to regulate use of metal halide light in certain
districts. Metal halide is prohibited
in Area ‘A’ except where the design engineer deems that colour rendering is
critical in which case the metal halide luminaires must be fully shielded.
Metal halide is regulated as it
produces white light which spans the full colour spectrum. Since it is not a
monochromatic light source like high pressure sodium, it is difficult if not
impossible to filter by astronomers.
With regard
to the reference to “per acre limit on light”, staff believe this is referring
to what is called “Unit Power Density” as practiced by the state of California.
The purpose of this is to limit the amount of power per unit area (e.g. 1
Watt/ft2) consumed by a lighting installation. The restriction is applied to private
lighting installations that are not part of the mandate of this policy. Roadway lighting is not included because
Unit Power Density minimum levels must be satisfied for safety reasons.
o) Comment:
General point:
Reduce light pollution.
Options: mandate
full cut-off everywhere (including decorative fixtures). Use more marker versus continuous
lighting. Lower wattages as much as
possible (subject to trade-offs of number of light poles); maybe even better to
lower lux (light flux) requirements.
Use expertise of International Dark Sky (?) Association (astronomers)
for technical expertise re: low light pollution approaches. Study leading edge cities’ approaches – eg.
I think Tucson Arizona (near Kitt Peak Observatory) has done some innovative
work. Explain to the general public
that brighter lights do not mean safer streets: a) bright lights lead to glare
and lower visibility in shadow areas. b) the normal human eye does not “dark
adapt”, so after exiting a brightly lit area a dim street will look dark at
first; but after a few minutes of adjustment visibility can be better! Use satellite photos of Ottawa at night (or
equivalent means) to monitor Ottawa’s lights pollution. Set as an objective of City policy to reduce
overall light.
Response:
One of the main objectives of the study was to reduce
light pollution. Full cut-off luminaires are proposed in all new residential,
employment, and mixed-use centre area developments and are required to be
considered for all other lighting designs in the city. Marker lights are proposed for rural estate
residential (reduction in light from current standard of full continuous
lighting). Upgrades from marker to full lighting in urban area residential are
not proposed in the new policy. Maximum
wattages are mandated based on luminaire type in the policy to avoid
over-lighting and glare issues. The
study team has involved representatives from the Royal Astronomical Society of
Canada in all stages of policy development.
The study team reviewed lighting policies from Tucson other
municipalities. Transitioning from lit streets to unlit or to streets lit at
lower levels will be carried out in accordance with accepted practice from the
Transportation Association of Canada.
Use of satellite photos to monitor light levels in Ottawa is one method
of monitoring on a qualitative basis light distribution and intensity in the
area. This approach may be more effective over the long term and particularly
if the City implements restrictions on maximum light levels on private
property.
p)
Comment:
I have been an amateur astronomer for some time, and I have built an observatory in my backyard. In the past I have contacted the City about the possibility to retrofitting the existing street lighting so that the light faces downward, rather than sideways (with the existing "cobra" style lights). My concerns seem to fall on deaf ears, despite words of encouragement by my local councillor Maria McRae. It would be encouraging for the City to work on this issue. Other Canadian cities such as Edmonton and Calgary have made progress in addressing this issue, with strong programmes to retrofit street lighting.
The lack of darkness is not only an issue for
astronomers but it also has an impact on health (lack of darkness leads to
sleep problems for people) and on wildlife (e.g. birds migrating). Also, it seems a waste of energy to not
shine lights properly. Good luck on
this issue.
Response:
Many of the streets in Councillor McRae’s ward have
street lighting at the former Ottawa standard of semi-cut-off light
optics (maximum 5% up light) and light levels at the lower one-half IESNA
standard.
Calgary,
for example, is replacing all existing luminaires with full cut-off luminaires
on existing poles except where the pole spacing is too large, ie., full cut-off
luminaires don’t distribute the light as well as cut-off or semi-cut-off
luminaires and hence may not always work with the existing pole spacing.
q)
Comment:
There should be mention of illumination levels
needing to be higher where the roadway is in an underpass. During the daytime
our eyes are accustomed to higher illumination levels and as a consequence when
entering underpasses our ability to see is impaired. With the impending
widening of the Queensway, underpasses become longer and darker during daytime.
Note that presently where Queen Elizabeth Drive and Col By Dr go under the
Queensway, the lights are on all the (albeit many of the lamps don't work).
Nice to see the use of halide lights instead of sodium, but what is the
increased operational and capital cost of this decision? It would nice to see
what the policy is with respect to maintenance of lights. I often request
repairs and find some take a long time to get done and there does not seem to
be systemic examination of by city employees that lights are out and rather
seems to rely on a complaints-based system. I note also that there are
increased numbers of lights that must be supplied by overhead lines as the
underground connections are no longer operational. It seems to take a long time
to get the underground connections fixed. You missed showing under
"Existing Light Equipment Used", Pg 8, the lights we have a lot of
here in downtown where a lamp arm has been stuck onto a hydro pole. Looks like
we will never get rid of that ugly configuration.
Response:
Underpasses are lit to the same levels as the
approach roads as this provides the best adaptation for the eye rather than
having to adapt to a higher level as you enter the underpass and then a lower
level after you exit. Tunnel lighting
on the other hand utilizes various lighting zones to allow the eye to adapt
from bright levels such as sunlight. In
these cases the tunnel lighting is on during the day. The design of tunnel lighting will be dealt with on a project by
project basis.

Comment:
When you're considering factors in ROW lighting policy, please
consider including a component requiring attention to potential impact on
adjacent natural habitat. There is quite a body of research indicating that
artificial lighting inhibits/ degrades breeding success by many of the small
wildlife species that contribute substantially to the long-term ecological
performance of natural habitats - especially woodlands. Some breeding
passerine (perching) birds, for example, do very poorly in woodland habitat
that is within the glare of artificial lighting. In its narrowest terms, such
an impact already constitutes a violation of the Migratory Birds Act and
some folks are getting more exercised recently about enforcing that legislation
more diligently. As you probably already know, this concern was factored into
the design requirements for sections of West Hunt Club Road through the
Greenbelt. Forgetting for the moment whether the light standards
selected were the most appropriate design to address the issue, the consideration
was most appropriate.
Any ROW lighting plan should include consideration of potential
light impact on natural habitat within 50 m of the ROW (that figure is a
guesstimate; there may be a more useful rule-of-thumb figure in the
technical literature). ROWs passing by
or within any of the City's ±190 designated Urban Natural Areas, for instance,
should be so flagged. (I'm working with the guys at Dillon who
are designing the Terry Fox Road section over the South March
Highlands and we've had just such a discussion). While you wouldn't need
biodiversity inventories or the like, a defendable landscape
assessment should be required in such cases to determine if native
breeding birds and/or other potentially light-sensitive fauna (e.g. amphibians,
indicator invertebrates) utilize the impact zone for breeding. If so, a
lighting design that minimizes such impact should result.
The evaluation is not a big deal and is not a big cost but should result in the conservation and/ or restoration of natural functions in hundreds of hectares of natural habitat in the City over the coming years. Might even reduce light pollution and energy use (operational cost) too ... win, win, win.
Response:
The draft policy was amended to include a section
dealing with lighting considerations for all right-of-way lighting projects
located within 50 metres of Category 1 and Category 2 Urban Natural Feature
areas.
A presentation was given to one Advisory
Committee as a result of circulation of the draft policy:
Comment:
Peter Hall, an OFGAC member, attended the Lighting Policy public
consultation at City Hall on Tuesday 10 April 2007. You were also kind enough to provide our Advisory Committee with
two briefings on the policy as it was developed – thank you.
It is beyond the Committee’s mandate to make comments about the majority of the items in the draft policy. We do note, however, that Section 5.3 (page 37) acknowledges that streetlights are occasionally shaded (seasonally) by trees. The policy further notes that “street trees will not be trimmed to accommodate the street lighting except as may be approved for special circumstances by the Director, Traffic and Parking Operations”.
Those “special circumstances” are not spelled out in the policy and we
hope that to the best of your units’ abilities, the City Forester will be
involved in any decision to remove a tree or severely prune it because of a
conflict with street lighting.
We also suggest that if shorter poles are used, especially in new installations
or when streets are being rehabilitated, trees will grow above the light
fixture and conflict will be avoided once that has occurred.
From an environmental perspective, moving to full or 95% cut-off
fixtures is a wise choice.
Night-lighting is becoming an increasing problem all over the
world.
Although there are little data on the impact of street lighting on
trees, it is possible that night lighting could affect a tree’s normal
physiological processes. So, reducing
night glare is a positive step. Dr.
Hall submitted a written comment on April 10 as to whether any investigation
had been done concerning the possible impacts on various types of lights
(spectrum, intensity etc.) on tree physiology.
If you do find data, we would appreciate a reply at some point on what
you learn. I had earlier consulted Dr.
Tito Scainio, an expert on photochemistry at the University of Ottawa, on this
very subject. He acknowledged that it
was an interesting question but one that had not been well studied. His expertise is the effect of light at the
cellular level and if leaves are impacted by artificial light, quality or
quantity, it would be at the leaf cellular level. May we suggest that the City urge the Canadian Forests Service of
Natural Resources Canada to consider conducting research on this subject as
part of its Urban Tree/Forests Program. Thank you again for your briefings and
for the opportunity to comment.
Response :
The City
Forester is aware of and agrees with the wording in the policy dealing with
tree trimming. City Environmental staff
was involved in the preparation of the section of the policy dealing with the
effect of light on trees and the approach to recognise and mitigate potential
impacts through future lighting designs.
t) Rockcliffe Park Residents Association
Comment :
Further to a letter to Scott Edey from Jane Dobell, then-President,
Rockcliffe Park Residents Association (RPRA) dated 27 October 2004 (copy
appended), the preferred option for lighting in the Heritage Conservation
District (HCD) of Rockcliffe Park is a metal halide 50 watt bulb having a
colour temperature of 3200K. That bulb
would be fitted in an acorn luminaire installed at the same height and on the
same type of bracket as the existing incandescent lights. We would hope that there would be continued
use of wooden poles and that the spacing between poles would remain “as
is”. As they burn out, the sodium
vapour luminaries would be replaced by acorn luminaires of the model manufactured
by Cooper Lighting. The same would be
true of the incandescent bulbs.
This replacement practice is, in fact, being followed now and we thank
you.
That said, Section 3.2.2 of the March 12 draft Right-of-Way Lighting
Policy states that “The style of poles, luminaires and light sources will be
selected as part of a future public consultation process on a
district-by-district basis… “. Should
you wish to hold further consultations with us, please let us know.
This letter also confirms that, except for Birch Avenue (a collector road on the east side of the HCD), there are no other collectors or arterial roads in Rockcliffe Park. The stretch of Maple Lane between Acacia and Springfield forms another boundary of the HCD. The Rockcliffe side of Maple Lane has several sodium vapour cobra-head luminaries on very tall concrete poles. If the opportunity arose, replacement of those fixtures with smaller scale poles and metal-halide bulbs in acorn-style luminaries would be an appropriate topic for consultation both with the RPRA and residents on both sides of the street. A precedent was set during the reconstruction of Birch Avenue for the installation of a shorter pole and residential-scale fixture.
We also note, that Section 5.3 acknowledges that street lights are occasionally shaded (seasonally) by trees. The policy further notes that “street trees will not be trimmed to accommodate the street lighting except as may be approved for special circumstances by the Director, Traffic and Parking Operations”.
Rockcliffe Park has many old and fine trees, some of which are in close
proximity to street lights. The
“special circumstances” are not spelled out in the policy and we request that
the Environment Committee of the RPRA together with City Forester will be involved
in any decision to remove a tree or severely prune it because of a conflict
with street lighting.
Finally, Appendix E illustrates lighting styles in existing HCDs but does not show the acorn-style luminaire nor does it mention Rockcliffe Park as a HCD. We suggest that you add both the acorn-style luminaire and mention of Rockcliffe Park in the final policy due out in June.
Response:
The Rockcliffe community is a
designated Heritage Conservation District the lighting of which, under the
policy as drafted, will be subject to a future public consultation process to
select lighting equipment. The City Forester is aware of and agrees with the
wording in the policy dealing with tree trimming.
u) National Capital Commission (NCC)
Comment: I am forwarding, for your consideration, consolidated
comments from NCC staff on the draft City of Ottawa Right-of-Way Lighting
policy. Thank you for the opportunity
to provide input. We trust it will be
useful in the finalization of your policy documents.
The policy is a good document, well written and easy
to use, with complementary graphics and illustrations. A general comment would
be that the City’s policy should be flexible in order that staff are empowered
to use their judgment, expertise and common sense in dealing with situations
where jurisdictions/ownerships overlap or transition from one to the other,
where there are special circumstances, or where there are partnerships or
agreements that may not fit existing Official Plan designations but require
special treatment. We realize that the
City is trying to regularize and standardize to the extent possible, and
commend this objective, but we also believe that there are special
situations that arise in the Capital on a regular basis that require
flexibility from a range of stakeholders.
Response:
Policy text revised to
allow for flexibility to address special or unforeseen circumstances.
Comment:
We note, in the final paragraph of this section, that this
policy does not apply to federal, provincial and greenbelt area roadways. For the Greenbelt in particular, the NCC
strives to create a unique setting and ambiance characteristic of a rural
area. We recognize that major arterials
pass through the Greenbelt, and are encouraged to see your reference to
project-specific reviews of proposed roads and lighting schemes. In this
respect, and in giving effect to the urban/rural transition and
illumination levels referenced in sections 3.3.4 and 3.3.5, special regard
should be given to these Greenbelt objectives, and wherever possible a shift
from an “urban to rural” lighting setting as quickly as is safely possible
should be fostered. We also wonder if
the Central Experimental Farm could be regarded as a unique rural setting,
albeit within the urban context, where a lower level of lighting, and
transition lighting from adjacent arterial roadways, could be considered.
Response:
Policy text in Section 3.4
already identifies that roads through land under the control of the NCC and the
MTO are subject to the lighting design requirements of those agencies. The text has been revised to also include
more generally that all land under the control of Federal and Provincial
governments is subject to other right-of-way lighting design requirements.
Comment:
Section 3.2: Special Areas
We are pleased to see identification of "special
areas" where pedestrian level lighting would be allowed, and where metal
halide ("white light") lamps would be used (as a superior light
source to high-pressure sodium). In
Section 3.2.1, we see the logic of these Special Areas from the Official Plan
policy perspective. Would it be appropriate to add Confederation Boulevard
or Federal Roads under the ownership of the NCC as an additional Special Area
within the Central Area in 3.2.1iii.)?
Regarding the last paragraph of
3.2, "when approved by Council.....without amendment to this Policy",
this seems to leave the "door open" for the City to add things to
their own policy. If a reference to Confederation Boulevard or Federal Roads
were added to the preceding paragraph, the possibility of future federal
options being included could also be possible.
Response:
Special Areas are
rights-of-way in locations under the control of the City of Ottawa. The text in Section 3.4 has been revised to
reflect that rights-of-way under Federal or Provincial control are to be lit on
a case-by-case basis in consultation with the appropriate agencies.
Comment:
Section 3.4: Other
Jurisdictions
This section further recognizes the jurisdiction and
lighting policies of the NCC and other federal and provincial governments,
departments or agencies. Our concern
here is attempting to be exhaustive in listing these situations, and also
providing a means for allowing new roads or cases to be included here, for
example, as site-specific approvals involving federal-municipal lands or
projects are granted in the future. The
list that appears in this section should perhaps be written as a non-exclusive
list or a list of main examples, as there may be changes to this list over
time. Major roads such as Experimental
Farm Drive and Lady Grey Drive should be added to the list. The sixth entry in the list just says
'parkways', which may be a typo. There are a
number of minor roads within the
City that are under the ownership of the NCC (Middle, Mill, Birch, Vimy, etc.)
which are not on the list.
Response:
The text of section 3.4 has been
revised to reflect that the list is partial and that other roads or areas under
the jurisdiction of upper tier governments exist and are subject to the
lighting requirements of those agencies.
Comment:
Confederation Boulevard is on this list, recognizing that
there is a unique agreement and set of policies that govern Confederation
Boulevard and which take precedence over this ROW policy. Perhaps more
reference to OP policies and maps would reinforce this, such as OP Annex 9,
Central Area Gateways, Nodes and Distinctive Streets or Policy excerpts from
the OP consolidation (January 2007) Volume 1, Section 3.6.6, policies 2 and 7,
referencing important considerations such as heritage, unique identity, view
sequences, linking points of political, cultural, historic and architectural
importance.
Response:
Changes to this section
are not recommended. The policies and
design requirements that will influence future lighting design on all
rights-of-way excepted from the policy will be identified and considered
appropriately at the time lighting design commences through that design
process. In this way the most current
and relevant influences on lighting design can be considered when the lighting
design occurs.
Comment:
There are other roads and bridges where special agreements
exist that govern the provision of lighting, including the Mackenzie King
Bridge and the Airport Parkway. In
other locations, such as Prince of Wales Drive, a special situation exists
where a section of Prince of Wales connects two parkways (QE and Experimental
Farm Drives), and ornamental lighting already exists. Should this section of Prince of Wales be included in a Special
Area due to its character and function?
Could the Special Area list or criteria be somewhat flexible, or perhaps
a schedule could be attached to the policy, to which additional existing
situations outside of your list, or future situations that are considered
special or subject to specific agreements could be added ? Perhaps the City would like to add a
statement referring to how it enters or might enter into negotiations and
agreements with other parties such as the NCC, and how context-specific
lighting specifications or undertakings could thus be developed.
Response:
All roads excepted from
the Policy in Section 3.4 are subject to the lighting design requirements of
the relevant agency. The text of this section has been changed so that it is a
partial list and that all such rights-of-way are to be lit on a case by case
basis in consultation with relevant agencies.
Comment:
Where developments occur on lands abutting certain federal
holdings, such as parkways, recreational pathways, intersections of pathways
and municipal infrastructure, bridge crossings etc., the NCC will be
implicated in a range of land use and design approvals in many instances.
These give rise to situations where the City's lighting policy document could
allow for the resulting recommendations from NCC's approval processes to be
implemented, if they are over and above what these standard specs are, without
an amendment to this policy? This recognizes that such recommendations may have
more to do with aesthetics than illumination levels.
Response:
The text changes made to
section 1.2 will allow the City to respond appropriately to special lighting
design input not foreseen in the Policy.
Comment:
Other Considerations
The intersection of NCC and federal roads and rights-of-way
may require transition level requirements to vary from the guidelines in the
TAC Guide for the Design of Roadway
Lighting. They may require lighting fixtures, lamps and reflectors, as well
as lamp post placement, to vary from normal standards. Merivale Road north of
the Queensway (connecting to Island Park Drive) is a good example, and it
would be better to light this short section according to NCC standards.
Response:
The text changes made to
section 1.2 will allow the City to respond appropriately to special lighting
design input not foreseen in the Policy.
Comment:
Federal facilities may have security lighting requirements
that could lead to requests to vary or alter the lamps, fixtures, placement or
intensity of light on public rights-of-way. Your policy could reference
the appropriate IESNA guidelines - G-1-03 “Guideline on Security Lighting for
People, Property, and Public Spaces”.
Response:
The text changes made to
section 1.2 will allow the City to respond appropriately to special lighting
design input not foreseen in the Policy.
Comment:
Lighting near airports must comply with the Aeronautics Act and its regulations.
Response:
A new section has been
added to the policy to clarify this requirement.
Comment:
There may be requirements for lighting to be reduced or
modified in order to avoid adverse effects on wildlife and wildlife habitat, on
nearby federal lands. For example, should evidence be found that lighting
negatively affects fish hatching areas or bird migration routes, there may be
situations where conditions for modified lighting approaches would be
appropriate.
Response:
The Policy has been
revised to address mitigating the potential effect of light on wildlife in
proximity to Urban Natural Features Areas. To address specific circumstances,
the NCC and other agencies would have opportunity for input to road lighting
design through the road design Environmental Assessment process.
v) Comment (public):
Having lived in Ottawa and still paying federal taxes remotely for its
upkeep, I welcome the opportunity to see Ottawa and its environs become a dark
sky friendly region in which the beauty and grandeur of the night sky can be
enjoyed by all of its citizens. It is important that Ottawa gets it right since
the resultant policy and bylaws will become a valuable template for the rest of
the Canada and whole world.
I've read the draft Ottawa Right-of-Way Lighting Policy - http://www.ottawastreetlighting.ca/
, and I see it as a step in the right direction.
But there are some areas which have not been adequately addressed, such as:
- showing the impact of light pollution on human health and their
circadian rhythms,
- showing the impact of light pollution on wildlife in the urban forests,
near the highways and streets and the residential areas,
- encouraging minimal wattage, motion-sensing, curfews and turning off
lights when they are not needed,
- explaining clearly that any light shone upwards or horizontally resulting in
sky glow, is wasted energy and is a major cost saving if it is mitigated.
- strongly deprecating the use of globes which are essentially glare bombs,
- providing guidance to show how existing fixtures can be replaced with dark
sky friendly fixtures such as sharp cutoff light fixtures.
- providing in the policy that the light trespass, glare, and its concomitant
sky glow are considered under the city's nuisance laws for which the
perpetrators can be fined

Attached are some useful references in dealing with the mitigation of
light pollution in Ottawa.
Response:
Carrying out detailed research on the
impact of light on human health was not part of the mandate of the study as
approved by Council. However, reducing
light trespass (light spillage) onto adjacent properties was a consideration in
selection of all lighting equipment styles in the policy. Use of full cut-off luminaires and lighting
at one-half the IES recommended light levels is proposed for all new
residential area lighting designs. This
will reduce the amount of light from streetlights entering adjacent residences.
A new section was added to the draft policy dealing with the effect of light on
trees and wildlife. The policy
encourages use of lower wattages in lighting design. Use of smart lighting systems was reviewed but not recommended
for use in the City at this time. Globe
lights are not part of the approved lighting equipment in the new policy. Use of full cut-off fixtures, depending on
the street being lit, will be used for future relighting projects. Light trespass, glare, and sky glow are not
proposed to be regulated by by-law given that this policy deals only with
public rights-of-way. Illuminated signs are regulated under the City’s Signs
By-law.
