SUMMARY
• In 2012, the Boulder City Council adopted the Colorado Chautauqua Guiding Principles
for Place Management and Fiscal Sustainability, a collaborative approach to changes in
the park, which has been used as a guide in the planning of this project.
• In 2016, the Landmarks Board approved a Landmark Alteration Certificate to
complete pedestrian improvements as part of the Community, Culture and Safety
Tax passed by voters in 2014. The work included the construction of new sidewalks,
retaining walls, and improved pedestrian crossings, as well as making the transit
stop ADA compliant. Pedestrian lighting was proposed as part of the application
but was removed to provide time for the City of Boulder and the Colorado
Chautauqua Association (CCA) to jointly develop lighting design guidelines.
• In 2017, the CCA and the City of Boulder developed the Chautauqua Park Historic
District Lighting Design Guidelines (“Lighting Design Guidelines”) to provide
guidance for exterior lighting.
• Due to the amount of public input in the development of the Lighting Design
Guidelines, review by the full Landmarks Board in a quasi-judicial hearing is
appropriate pursuant to Section 9-11-14(b) B.R.C. 1981.
• Staff recommends approval of the installation of the pedestrian lighting within the
historic district, with final details to be reviewed and approved by the Ldrc. See
Attachment B-1: Project Narrative for additional information on the project
background.

PROJECT BACKGROUND
In 2014, the Community, Culture and Safety tax (Ballot Measure 2A) was approved by
voters for a “Chautauqua Pedestrian Safety, Access, and Lighting Improvements
Project.” In 2015 and 2016, the Landmarks Board reviewed two Landmark Alteration
Certificate (LAC) applications for the public improvements, including installation of
lighting from the King’s Gate entrance to the parking lot east of the tennis courts and at
Agenda Item #6A Page 4
the King’s Gate Shelter House and the Arbor in the Chautauqua Park Historic District.
The Landmarks Board approved pedestrian improvements, including construction of a
sidewalk on the south side of Baseline Road from 6th Street to the King’s Gate,
construction of a sidewalk on the east side of Kinnikinic Road into the park from
Baseline Road and reconstruction of the drainage swale along the east side of Kinnikinic
Road. The Board did not approve the lighting applications, presented by the Public
Works Department and based on the CCA’s Master Exterior Lighting Plan (MELP).
The 2015 LAC application proposed installation of the following light fixtures:
• Ten lights at the Arbor, drilled into the log beams to minimize visibility;
• A single light fixture in the interior of the King’s Gate Shelter House;
• Six 14’7” tall “acorn” light fixtures located between King’s Gate and the Tennis
Courts, three 18.5’ tall arched light fixtures (two located at the Tennis Court
Parking Lot and one replacing the street-light along Sumac Drive northwest of
the Arbor).
The Landmarks Board decision not to approve the application was based upon the
Board’s finding that the proposed lighting was inappropriate and that the MELP,
developed by the CCA but not adopted by the Landmarks Board, did not provide
adequate guidance to determine the appropriateness of exterior lighting within the
historic district. The review process highlighted the need for comprehensive lighting
design guidelines to assess whether the proposal met the standards for a Landmark
Alteration Certificate.
In 2017, the City of Boulder and the CCA jointly developed the Chautauqua Park Historic
District Lighting Design Guidelines, using the Collaborative Stewardship Framework. The
document provides a framework for decision-making through the documentation of the
historic use of lighting at Chautauqua, assessment of current needs, guiding principles,
recommendations and design guidelines. The city hired consultants Mundus Bishop
and Clanton and Associates to complete the project. The nine-month process included
feedback from CCA Board representative, the Landmarks Board, city departments, a
community working group, public open houses and online surveys. The current
lighting proposal is based on the newly-adopted design guidelines.
CHAUTAUQUA PARK HISTORIC DISTRICT – DESCRIPTION AND HISTORY
The Colorado Chautauqua is located in southwest Boulder at the foot of Green
Mountain, bounded by City of Boulder Open Space and Mountain Parks land on three
sides and Baseline Rd. on the north. The historic district, which encompasses 40 acres,
includes five large public buildings, more than 100 residential cottages, and several
landscaped open spaces. Chautauqua Park was designated as a local historic district in
Agenda Item #6A Page 5
1978 and was designated as a National Historic Landmark (NHL) in 2005 in recognition
of its exceptional significance and intact historic integrity.1 Currently, there are only 25
NHLs in the state of Colorado. It is widely recognized as being the best preserved
surviving Chautauqua in the country.

The Chautauqua movement began in upstate New York in 1876 as a center for political,
educational, and recreational programs. By 1924, nearly 40 million people were
annually attending events at various Chautauquas across the country. In the late 1890s,
a group of Texas educators, including the president of the University of Texas, wanted
to open a Chautauqua and looked to the Rocky Mountains as a location. Boulder was
chosen for the site and its citizens, thrilled to have a Chautauqua nearby, raised $20,000
towards construction costs to further encourage the venture. The Texas-Colorado
Chautauqua was opened on July 4, 1898 on 171 acres that the City of Boulder purchased
from the Bachelder Ranch. Since its inception, the City of Boulder and the Colorado
Chautauqua Association have managed the site in partnership.
Chautauqua saw a number of improvements during the 1910s and 1920s. By 1910, the
tents had been replaced with small frame cottages, which today define the residential
area of the park. In addition, a few new public buildings were constructed, including
the Mission House, Community House, and the Columbine Lodge. In 1923, a large

reservoir was dug at the southern end of the park. Due to economic pressures and
changing trends in recreation during the Great Depression, Chautauqua saw an overall
decline in attendance and programs during the 1930s. As the buildings became
increasingly dilapidated due to reduced use, the University of Colorado took over
about half of Chautauqua’s cottages as housing for students, which helped contribute to
Chautauqua’s survival. By 1955, Boulder’s Chautauqua was one of only six remaining
in the country. The programs and activities continued as they had from the beginning,
but the buildings continued to deteriorate, and by 1975 the City of Boulder considered
demolishing Chautauqua’s buildings. However, widespread concern about the future
of the park resulted in the listing of Chautauqua in the National Register of Historic
Places in 1978, sparking the park’s revival.
Chautauqua Today (2017)2
The cultural and educational mission of the Chautauqua continues today through
concerts, lectures, and social events. Use tends to peak during the summer, however, the
Dining Hall and special events draw people to Chautauqua year-round and at various
times during the day. In 2016, forty community events were held at the Community
House in the evening, hosting 4,675 attendees. Numerous private events, including
wedding receptions and award programs were also held.
Visitors and newcomers alike enjoy the different amenities Chautauqua has to offer. Over
40,000 people attended performances at the Auditorium in 2016 and the Dining Hall
averages 3,500 customers per week. Staff and volunteers support various activities and
events, often arriving earlier and staying later than the scheduled event times. Cottagers,
lodging guests and hikers navigate through the historic district on a regular basis.
King’s Gate and the Arbor
Note: The LAC application proposes the installation of lights at the King’s Gate Shelter House
and the Arbor.

Agenda Item #6A Page 7
The King’s Gate entrance and Shelter House, also referred to as the Trolley Stop, is
located along Baseline Road and is located at the original entrance to the Chautauqua
when it opened in 1898. The following description is excerpted from the Chautauqua
Landscape Assessment3:
The Shelter House is the second structure constructed on were site, built in 1917 as a
waiting area for streetcars and replacing an earlier carriage gateway. The stone shelter,
concrete terrace and steps, and its adjoining walls are of the rustic style that was
prevalent during the early 1900s. The pedestrian opening in the walls that surround the
shelter directly aligns with the Dining Hall and the Arbor. The two shelters replaced the
original ticket booth that was built in 1898 and moved during the early 1900s.
Through the development of the Lighting Design Guidelines, it has been determined
that the King’s Gate “lanterns” were not historically lit.
Figure 4. Arbor, 1915 (left) and 2018 (right).
The rustic 1917 arbor is located on the walkway from King’s Gate to the Dining Hall
and was built as a resting stop for those walking up or down the path. Composed of
several squared stone rubble piers that taper in width, the roof of the arbor is made up
of an oval pergola of log beams, most of which have been replaced over the years. Stone
benches are located in the interior.
History of Lighting at Chautauqua4
The introduction of electric lighting at Chautauqua in 1898 followed the development of
lighting elsewhere in the city. Electric lights were first installed in downtown Boulder in

1886, through funding by private business owners, who sought to reduce the need to
carry personal lanterns “to avoid falling in mud-holes or irrigation ditches.”
In 1890, the Boulder City Council passed a motion to build 27 street lights in
collaboration with the Electric Light Company. The Boulder County HERALD reported
on this development in an article “Splendidly Lighted: Boulder to Have Twenty-Seven
Arc Lights on the Streets,” in which they describe security as being an “important
element” of the lighting installation, as well as the experiential quality of arriving to a lit
town, which they considered to be impressive, grand, friendly and warm. The paper
considered “the move a grand, good one.” These sources indicate that electric street
lighting was viewed as mainly utilitarian in nature and also signified safety, comfort,
and enjoyment of a place at night time.
Lighting at Chautauqua was also regarded as adding to the beauty of the place: “There
were few buildings or trees between the University and the Chautauqua grounds, and
the ‘brilliant cluster’ of the lights glittered, according to one reporter, ‘like so many
gems in the distance.’”

The Boulder County HERALD reported in June of 1899 that the “The Chautauqua
grounds were lighted up last night with arc lights for the first time this year. They
looked exceedingly beautiful.” The original lighting fixtures were mounted to tall wood
electrical poles and supplied lighting to key locations within the campus, including the
Dining Hall, Auditorium, and parking area. The lighting poles and fixtures appear to
Agenda Item #6A Page 9
have been utilitarian in style and did not provide any daytime aesthetic or decorative
purpose.
Historic photographs show utility poles with suspended luminaires and literature refers
to arc lights at the Chautauqua. Arc lamps were astringent and brilliant, with a very
high color temperature and a very small source. They were much more powerful than
the contemporary incandescent lamps of the time. The lit areas directly below an arc
lamp would have been very bright with distinct shadows. The wide spacing of the
lights would have had very high ratios of uniformity so that spaces between lit areas
would seem very dark. The surrounding context was dark, with the night sky and
foothills as a background, so the contrast between illuminated and dark areas would
have been very great. Photographs indicate little or no shielding to the lights, so the
output was not controlled but cast an even amount of light in most directions. Overall,
the original lighting at Chautauqua would have been glary and the uniformity very
wide.
PROJECT DESCRIPTION
The current project proposes the installation of five pedestrian light fixtures along the
path between King’s Gate and the Dining Hall, three light fixtures at the Tennis Court
parking lot, four lights at the Arbor and one light at the King’s Gate Shelter House. See
Attachment A: Current Photographs and Attachment B-1: Project Narrative.

DESIGN GUIDELINES
The Historic Preservation Ordinance sets forth the standards the Landmarks Board
must apply when reviewing a request for a Landmark Alteration Certificate and the
board has adopted the Chautauqua Park Historic District Lighting Design Guidelines, the
Chautauqua Park Historic District Design Guidelines and the General Design Guidelines to
help interpret the ordinance. The following is an analysis of the submitted proposal
with respect to relevant guidelines. It is important to emphasize that design guidelines
are intended to be used as an aid to appropriate design, and not as a checklist of items
for compliance.
CHAUTAUQUA LIGHTING DESIGN GUIDELINES
The Chautauqua Park Historic District Lighting Design Guidelines were developed and
adopted by the CCA Board of Directors and the City of Boulder Landmarks Board in
2017 to assess the appropriateness of exterior lighting proposals at Chautauqua. The
design guidelines identify seven lighting areas to acknowledge the variety of spaces
and uses within the Chautauqua Park Historic District. In addition to the general
approach to lighting, recommendations are made for each lighting area. The lighting
areas are intended to be broad, illustrative and not to represent firm boundaries; some
locations may fall into two lighting areas.
Agenda Item #6A Page 16
Figure 13. Lighting Areas Map, Chautauqua Lighting Design Guidelines
Needs Assessment 5
Input was gathered over the course of the development of the Lighting Design
Guidelines through meetings, study sessions, open houses, a feedback booth, an online
survey, and an evening walking tour. Participants included representatives of five city
departments and CCA staff, five community groups, the Landmarks Board and CCA
5 Chautauqua Lighting Design Guidelines, p. 24-26.
Agenda Item #6A Page 17
Board of Directors, community members, concert-goers and Dining Hall employees.
While there was a wide variety of opinions, there was general agreement in a number of
areas. Namely, that a conservative approach to lighting is appropriate, that different
areas of Chautauqua require specialized approaches to lighting, that the need for
lighting should be clearly documented. In terms of lighting qualities, the majority of
participants considered that lighting approaches should minimize light pollution and
light trespass and provide lighting only when and where it is necessary. To that end,
there were many suggestions that lights be programmed to be turned down or off when
they are not needed.
Most participants indicated that lighting is needed for safety, to reduce tripping
hazards, and wayfinding. While there were many people who considered lighting is not
needed for security purposes, the majority of Dining Hall employees that responded to
a survey expressed a desire for increased lighting between the Dining Hall and the
Tennis Court Parking Lot, which they typically access late at night and early in the
morning. Residents and staff reported interactions with bears and other animals acros s
the campus after dark.
Parking/Vehicular Circulation
In general, participants indicated that streetlights, located at key intersections, provided
adequate lighting, but that the fixtures could be improved by reducing the level of spill
onto lawns and into houses and by carefully trimming vegetation that currently
obscures the light source. Improved lighting is needed along the path to the Tennis
Court parking lot and at the parking lot to provide a consistent level of light to see one’s
car and to address security concerns of employees and volunteers that use this lot. Stairs
and other tripping hazards should be adequately lit.
Primary Pedestrian
The network of sidewalks is used on a daily basis by concert-goers, Dining Hall and
Colorado Music Festival employees and volunteers, residents and visitors of all ages
and abilities. Lighting is needed for navigation and to reduce tripping hazards (safety).
Some participants indicated that lighting was needed at the Arbor and between the
King’s Gate entrance at Baseline Road and the Auditorium, to address security and
wayfinding concerns.

1.0 General Lighting Design Guidelines
Guideline Analysis Confor
ms?
1.1 Improve existing lighting by modifying or removing inappropriate luminaires.
1.1.1 Ensure existing and new luminaires are
properly installed so light is directed
downwards and does not spill onto
adjacent areas.
Fixtures are full cut-off and
designed so the light will not
spill beyond the intended area.
Yes
1.2 Approach lighting holistically to avoid incremental change that may lead to a
higher overall illumination of the historic district.
1.2.1 In new lighting proposals, consider lighting
either by building or area, taking into
consideration the overall impact of existing
and proposed illumination.
The application considers the
pedestrian path from the King’s
Gate Shelter House to the
Tennis Court Parking lot, taking
into consideration the existing
street lights near the green and
along Baseline Road.
Yes 1.2.2 Ambient light from adjacent buildings and
fixtures may contribute to lighting levels
and should be considered when designing
new lighting.
1.2.3 Provide a consistency of luminaire design
and aesthetic within the historic district.
Lighting qualities, including color
temperature, should have a consistent
warmth and appearance across the
landscape.
The light fixtures have been
selected to establish an
aesthetic that fits these
recently-adopted design
guidelines.
The color temperature is a
consistent 3000K (warm white)
across the proposed fixtures.
Yes
1.2.4 Consideration should be given to users
with visual impairments, and the variety of
users in age and ability.
The project is part of the
Community Culture and Safety
tax which aimed to provide the
community with safer,
accessible pedestrian routes.
The proposed lighting is along
the path that is frequently used
by visitors, employees and
neighbors.
Yes
1.3 Preserve the night sky, architectural character, views, and historic integrity of the
historic district by lighting areas and features only when and where need has been
demonstrated.
1.3.1 Avoid lighting where and when it is not
required and illuminate only where need
has been clearly established.
The Design Guidelines identify
a need for lighting in the Tennis
Court Parking Lot to address
security concerns and along
the path, at the arbor and

King’s Gate Shelter House for
navigation and to reduce
tripping hazards. (p. 24)
1.3.3 Light spill onto adjacent properties outside
of the historic district should be avoided.
Lighting is designed to be
contained within the intended
area and not spill into the
adjacent Chautauqua Green or
private properties to the east.
Yes
1.3.4 Design lighting utilizing Dark Sky Friendly
qualities, including the following.
• Lights should be no brighter than
necessary. • Fixtures should have no spill
or limited spill, be Full Cut-off or have a B-
U-G Rating with Uplight=0.
The fixtures have been
selected utilizing Dark Sky
qualities, including a B-U-G
rating of Uplight = 0; be Full
Cut-off; and be 3000K to not be
excessively bright.
Yes
1.4 Design lighting to facilitate navigation and address safety concerns.
1.4.1 New fixtures may be appropriate at
destination points with points of light at the
beginning and end of paths so a
pedestrian may find their way.
• Additional points of light may be
appropriate where needed to further
facilitate navigation and address safety
concerns. • The greatest uniformity should
not exceed 15:1.
Plans show fixtures at the
beginning and end of the
pedestrian path, with additional
points of light at the Arbor to
facilitate navigation and
address safety concerns.
Yes
1.5 Utilize a programmable control system to turn off lights when they are not needed
and to dim the output for the time of night and occasion.
1.5.1 Recognize the varied use of the campus
throughout the day, week and season and
modify lighting times and locations as
needed. The lighting will be turned on
an hour before dusk, dimmed
to 50% at 2 am, and then
turned off at dawn.
Yes 1.5.2 Luminaires should have addressable
wireless control modules that
communicate with the programmable
control system.
1.6 Select new fixtures that are simple in design and respect the utilitarian character of
the historic district’s original lighting.
1.6.1 New lighting in the historic district should
generally be unobtrusive and compatible
with the overall historic character of the
buildings, sites, and streetscapes of the
historic district.
Staff considers the proposed
lighting qualities and fixtures
will be unobtrusive and
compatible with the overall
historic character of the historic
district.
Yes
Agenda Item #6A Page 20
1.6.2 Select poles and luminaires that are
neutral in design, and do not create a new
aesthetic or ahistorical character.
Staff considers the proposed
fixtures are neutral in design
and do not create a false sense
of history.
Yes
1.6.3 New fixtures with
components that
reference, but that
do not replicate,
character-defining
features of the
original fixtures
may be
appropriate.
Character-defining
features include
orthogonal cross
beams, a cone-
shaped pendant,
tapered pole and
unornamented
design. Reference
Figure 1.
The proposed fixtures were
based on Figure 1 of the
lighting design guidelines, and
seek to reference the
orthogonal cross beams,
tapered pole and
unornamented design. A
suitable cone-shaped pendant
was not identified in the
selection of the fixture
components.
Yes
1.6.4 Select materials, colors, and finishes that
are simple and blend with the existing
materials in the historic district.
The fixtures along the
pedestrian path are proposed
to be a combination of wood
and painted metal. Staff
considers natural wood to be
an appropriate material that will
age over time and blend in with
the setting. Staff considers the
metal fixtures in the parking lot
and the bell hoods to be
appropriate and should be
finished with a matte black
paint. Confirm real wood
materials on poles; staff
considers a synthetic, wood-
like product would be
inappropriate.
Maybe
1.6.6 It is not appropriate to introduce replica
luminaires that mimic a time or place other
than what is documented at Chautauqua,
as these create a false sense of history.
The proposed fixtures do not
create a false sense of history. Yes
Agenda Item #6A Page 21

Chautauqua Park Historic District Design Guidelines – Analysis
PUBLIC IMPROVEMENTS
Public improvements are especially important to the character of Chautauqua, and include
such elements as streets, public parking, curbs, gutters, stone walls, benches, street lights,
water foundation, and signs. The addition of contemporary examples of these elements
have a greater impact on Chautauqua than on some other historic areas because so much of
the Chautauqua site remains little changed. Whenever considering public improvements or
changes to existing improvements, every attempt should be made to fit them into the
existing historic site character. This may require modification, waiver of change to
standards applied elsewhere for public improvements.
Analysis:
This pedestrian lighting proposal is based on the recently adopted Lighting
Design Guidelines, which were collaboratively developed by CCA and the City of
Boulder over the course of 9 months. The proposed lighting seeks to integrate and
not detract from the character of the historic district, and provide the minimum
amount of light to meet the needs determined in the Lighting Design Guidelines
and the objectives of the Community, Culture and Safety Tax.
STREET LIGHTS, STREET SIGNS, BENCHES, FOUNDATION AND OTHER
SITE FURNITURE
These elements were originally simple and utilitarian, not elaborate and ornate.
There are a number of companies that manufacture historic reproductions from
many periods. Since the development of Chautauqua spanned several decades,
there may be a good selection of appropriate site furniture; however, simplicity is
the most important consideration.
Analysis:
The proposed lighting fixtures are simple and utilitarian, not elaborate and ornate.
Agenda Item #6A Page 25
General Design Guidelines – Analysis
8.5 Lighting
Traditionally, site lighting was very limited in residential districts. While today there is typically
a need for more lighting and higher levels of illumination, both building lighting and site
lighting should respect the quality of lighting that characterizes historic residential districts.
When selecting specific fixtures and locations, it is also important to consider the impact of
site lighting on adjacent properties
Guideline Analysis Conforms?
8.5.2 It is inappropriate to introduce or
eliminate exterior lighting fixtures
if doing so will detract from the
overall historic character of the
building, site, or streetscape
Due to the simple style of the
lighting fixtures, the lighting
qualities, and the programmable
controls, staff considers the
lighting fixtures will not detract
from the overall historic character
of the building, site or streetscape.
Yes
8.5.3 Lighting should be functional ―
not just decorative
Lighting is designed to meet the
needs assessment of the Lighting
Design Guidelines and the
objectives of the Community,
Culture and Safety Tax and not be
decorative.
Yes
Staff considers that care has been taken in the selection of light fixtures, light qualities
and proposed locations. The proposal was shaped by the recently-adopted Chautauqua
Park Historic District Lighting Design Guidelines, which determined that lighting at the
Arbor and King’s Gate Shelter House, along the pedestrian path from the Shelter House
to the Auditorium, and at the Tennis Court Parking Lot may be appropriate. The
proposed lighting fixtures follow Guideline 1.6.3: “New fixtures with components that
reference, but that do not replicate, character-defining features of the original fixtures
may be appropriate. Character-defining features include orthogonal cross beams, a cone-
shaped pendant, tapered pole and unornamented design.” Additionally, the light
qualities meet the specifications in the design guidelines, including a warm color
temperature, limited light spill, Dark Sky Friendly, and programmable controls to dim
the lights from 2 a.m. until dawn and turn the lights off during the day.
Staff considers wood to be an appropriate material for lighting fixtures in the Chautauqua
Park Historic District. The natural material may contribute to the district’s rustic
character without creating a false history, and the material is intended to age over time.
A sample of the material is anticipated to be available for the board’s review on June 6;
staff considers confirming the authenticity of the wood material is an important factor in
the recommendation to approve the application. If the wood pole is wood composite
material, staff considers a metal pole may be an appropriate alternative.
Agenda Item #6A Page 26
Staff considers the proposed lighting will meet the applicable design guidelines and
recommends the board approve the application.
FINDINGS
Subject to the conditions stated in the June 6, 2018 staff memorandum, staff recommends
that the Landmarks Board approve the application and adopt the following findings:
Providing the listed conditions are met, this decision will be consistent with the purposes
and standards of the Historic Preservation Ordinance (Chapter 9-11, B.R.C. 1981) in that:
1. The proposed installation will not adversely affect the special character or special
historic, architectural, or aesthetic interest or value of the historic district. Sec. 9-
11-18(b)(2), B.R.C. 1981.
2. The proposed new construction will generally comply with Sections 1.0 General
Lighting Guidelines, 4.0 Parking/Circulation and 5.0 Primary Pedestrian, of the
Chautauqua Park Historic District Lighting Design Guidelines; with the “Public
Improvements” and “Street Lighting” sections of the Chautauqua Park Historic
District Design Guidelines; Section 8.5 “Lighting” of the General Design Guidelines
and; Section 9-11-18(b)(3), B.R.C. 1981.

Landmarks Alteration Certificate Application--Lighting
May 24, 2018
Chautauqua Pedestrian Safety, Access and Lighting
Improvements Project
In 2017, the City of Boulder Public Works department completed the majority of the improvements
listed in the 2014 voter-approved Community, Culture and Safety tax, which aimed to provide the
community with safer, accessible pedestrian routes at Chautauqua. Improvements completed as part of
the Chautauqua Pedestrian Safety, Access and Lighting Improvements Project (Chautauqua Project)
included:
• Constructing a sidewalk on the south side of Baseline Road from 6th St. east to the historic
trolley and current transit stop (also known as King’s Gate) near the park boundary west of 10th
Street;
• Improving pedestrian crossings at intersections within the project area;
• Providing pedestrian connections from Baseline Road to Open Space and Mountain Parks
(OSMP) designated access trails and existing Chautauqua Park paths; and
• Making the existing transit stop compliant with the Americans with Disability Act (ADA).
For additional information on the Community Culture and Safety Tax projects, see the Aug. 4, 2014 City
Council Memo.
The current Landmark Alteration Certificate (LAC) application proposes the installation of pedestrian
lighting within the Chautauqua Park Historic District. The lighting portion of the Chautauqua Project was
put on hold as the City of Boulder and Colorado Chautauqua Association (CCA) collaboratively developed
Lighting Design Guidelines. In November 2017, the Landmarks Board and CCA Board of Directors
unanimously adopted the Chautauqua Park Historic District Lighting Design Guidelines (“Lighting Design
Guidelines”).
Project Purpose
The project team seeks to honor Chautauqua’s National Historic District designation and the
Chautauqua Lighting Design Guidelines through design and material selection for the proposed lighting,
while providing important pedestrian safety improvements. The installation of lighting will complete the
improvements listed in the 2014 Community Culture and Safety tax.
Project Description
This application proposes the installation of pedestrian lighting along key paths within the Chautauqua
Park Historic District, from the historic trolley and current transit stop (King’s Gate) and along the path
to the 12th Street parking lot. Specifically, the application proposes:
• Five (5) 18-foot tall wood pedestrian light poles stained Ebony (S7) with Jet Black (C7) metal
bases mounted at 14-feet with Type II skirted bell hood fixtures with a black (BLK) finish on the
path between King’s Gate and the 12th Street Parking Lot (Tennis Court Parking Lot)
• Sensitively integrated lighting within the historic Arbor (four downward directed fixtures) with a
Satin Bronze (BZP) finish and King’s Gate Shelter House (1 upward directed fixture) with a
Bronze Hammertone finish
Agenda Item #6A Page 36
• Three (3) 18-foot tall metal parking lot light poles with a Black Finish Painted (FP) mounted at
14-feet with Type III skirted bell hood light fixtures within the 12th Street Parking Lot with a black
(BLK) finish

Guidance
Chautauqua Lighting Design Guidelines
The project team developed this proposal based on the recently approved Lighting Design Guidelines,
and in consultation with the Colorado Chautauqua Association Building & Grounds Committee. The
Lighting Design Guidelines determined that pedestrian scale, programmable, Dark Sky friendly lighting,
selected to be sensitive to the historic setting, located along the existing pedestrian paths from King’s
Gate to the parking area on 12th Street may be appropriate. The design guidelines also state that lighting
the interior of the Arbor and King’s Gate Shelter may be appropriate, taking care to protect historic
material and integrate fixtures to be minimally visible.
All lighting options presented within this application follow the recommended approach and design
guidelines in the design guidelines.
Special considerations:
• Lighting from the existing street-lights was taken into account in determining the placement
and need for new fixtures (1.2.2)
• Lighting is proposed only where need has been determined (1.3.1)
• Fixtures were selected to utilize Dark Sky Friendly qualities (1.3.4) and facilitate navigation and
safety concerns (1.4)
• The fixtures utilize a programmable control system to turn off lights when they are not needed
(1.5)
• The fixtures were selected to be simple in design and respect the utilitarian character of the
historic district’s original lighting (1.6)
• The poles are located on the east side of the path from King’s Gate to minimize the visual
impact on the view toward the Flatirons
• The pedestrian and parking lot poles are proposed to be 18’ in height, a scale that will not
overwhelm the historic setting and be compatible with the historic buildings and landscape
(1.7)
• The lighting qualities, including color temperature, glare and balance, respect the historic
character of the district (1.8)
• The proposed fixtures are energy efficient and meet the city’s Energy Conservation Code (1.9)
• The proposed lighting in the Park/Vehicular Circulation area is limited to major intersections
and have a limited spill (4.1.1)
• Lighting is designed to be managed according to daily/weekly/seasonal uses (4.3 and 5.2)
Agenda Item #6A Page 37
• Lighting in the Primary Pedestrian area is designed to provide for navigation, in intervals
sufficient to see from one light location to another (5.1.2)
• Lighting in the interior of the Arbor and King’s Gate takes care to protect historic material;
fixtures will be minimally visible (5.3)
City of Boulder Land Use Code
The City of Boulder Land Use Code, 9-9-16 Lighting, Outdoor, also provides guidance and requirements
in the selection, location, operation and maintenance of exterior lighting. All lighting options presented
here meet the requirements of the Land Use Code.
Boulder Energy Code
All proposed lighting options meet the City of Boulder Energy Conservation Code, which regulates
energy use and control strategies.
Sequence of Review
At their April meeting, the Colorado Chautauqua Association Building & Grounds Committee has
reviewed and voted in support of the light fixtures, locations and installation methods proposed in this
Landmarks Alteration Certificate. The recommendation of the committee will be shared with the
Landmarks Board during the presentation for this application (June 6).
The project team requests that the Landmarks Board approve this Landmarks Alteration Certificate for
the installation of the proposed light fixtures and locations at their June 6, 2018 meeting.
Need for Lighting (Current Context)
Chautauqua Park, Open Space and Mountain Parks (OSMP) trails and CCA lodging, programming and
venues, combined, attract more than half a million visitors per year to Chautauqua. Use tends to peak
during the summer, however, the Dining Hall and special events draw people to Chautauqua year-round
and at various times during the day. In 2016, 40,000 people attended performances at the Auditorium
and the Dining Hall averaged 3,500 customers per week.
Such special events, programming and other attractions bring visitors, performers and employees to
Chautauqua during low light conditions, such as evening musical performances or talks. Staff and
volunteers support various activities and events, often arriving earlier and staying later than the
scheduled event times. Cottagers, lodging guests and hikers navigate through the historic district on a
regular basis. Residents and staff reported interactions with bears and other animals across the
Chautauqua campus after dark.
This application proposes adding pedestrian lighting to the existing unlit pedestrian paths that link the
12th St. parking lot and King’s Gate to the Dining Hall and performance areas and venues. Performers
and Chautauqua staff are assigned parking in a lot on 12th Street, while the HOP 2 Chautauqua, a free
City of Boulder transit service to the Colorado Music Festival and Chautauqua Summer Series events,
provides service to the King’s Gate transit stop on Baseline Road.
In approving the 2014 Community, Culture and Safety tax, visitors, the Colorado Chautauqua Association
and the voters identified the unlit paths as a safety concern. The Lighting Design Guidelines further
assessed the need for lighting within the boundaries of the Chautauqua Park Historic District through
board and working group input, community open houses, a walking tour and survey of Dining Hall
employees and concert-goers. The Lighting Design Guidelines acknowledge that the increased number
of evening events and the diverse set of users, including people of all ages and abilities, necessitated
exterior lighting of a design to have the least amount of impact while meeting the safety, security and
navigational needs that have been expressed through the public process.
Agenda Item #6A Page 38
The Lighting Design Guidelines identified the areas where lighting is currently proposed as
“Parking/Vehicular Circulation” and Primary Pedestrian.” The following are excerpts from the Need
Assessment of the Lighting Design Guidelines:
Parking/Vehicular Circulation
In general, participants indicated that streetlights, located at key intersections, provided
adequate lighting, but that the fixtures could be improved by reducing the level of spill onto
lawns and into houses and by carefully trimming vegetation that currently obscures the light
source. Improved lighting is needed along the path to the Tennis Court parking lot and at the
parking lot to provide a consistent level of light to see one’s car and to address security concerns
of employees and volunteers that use this lot. Stairs and other tripping hazards should be
adequately lit.
Primary Pedestrian
The network of sidewalks is used on a daily basis by concert-goers, Dining Hall and Colorado
Music Festival employees and volunteers, residents and visitors of all ages and abilities. Lighting
is needed for navigation and to reduce tripping hazards (safety). Some participants indicated
that lighting was needed at the Arbor and between the King’s Gate entrance at Baseline Road
and the Auditorium, to address security and wayfinding concerns.
Funding & Budget
The 2014 voter-approved Community, Culture and Safety tax provides $250,000 for selection and
installation of lighting in the project area. To date, approximately $75,000 of these funds has been used
on design, including the development of the Chautauqua Park Historic District Lighting Design
Guidelines.
Background
October 7, 2015
The project team introduced the Chautauqua project to the Landmarks Board under Matters on October
7, 2015. Regarding lighting, the Landmarks Board’s initial response expressed concern for lighting within
the park and its impact to its historic character. In response, the project team changed the style of the
proposed pedestrian lighting to match the existing acorn style lighting currently installed within the
historic district boundary.
February 3, 2016
The project team submitted a Landmark Alteration Certificate (LAC) application for consideration at the
February 3, 2016 Landmarks Board meeting. The Landmark Board opposed pedestrian lighting, stating:
• Lighting is inappropriate for the “camp like feel” of Chautauqua; installing lighting would ruin
the ability to view stars from inside the park; lighting is unnecessary in Chautauqua because no
data shows the lack of lighting is unsafe; and the lighting associated safety concern could be
resolved through distribution of flashlights to performers, visitors and staff
o Only lighting King’s Gate was supported by the majority of board members
The project team removed lighting from that application to allow for the Colorado Chautauqua
Association and the Landmarks Board to develop lighting design guidelines over the next year (2016-
2017), anticipating that the Chautauqua project would be the first application under the new design
guidelines.
Agenda Item #6A Page 39
April 6, 2016
The project team submitted a third LAC application and received approval for the remaining project
improvements within the historic district:
• Fieldstone swales along both sides of Kinnikinic Road, from Baseline Road to Bluebell Road on
the west and Baseline Road to Sumac Drive on the east
• Crusher fines social path from the re-constructed Queen’s Gate, at Baseline Road and Lincoln
Place, into Chautauqua Park to guide park users away from historic oak tree roots
• Five-foot wide, exposed-aggregate concrete detached sidewalk on the east side of Kinnikinic
Road within the historic district boundary
Nov. 7, 2017
The Chautauqua Park Historic District Lighting Design Guidelines (“Lighting Design Guidelines”) were
unanimously adopted by the City of Boulder Landmarks Board and CCA Board of Directors, following an
8-month collaborative process.
Jan. 25, 2018
The Lighting Design Guidelines went into effect, following an amendment to provide addition guidance
on the selection of fixtures and following a 15-day public comment period.
