STATISTICS: 1. Site: 900 Baseline Rd., Chautauqua Park 2. Zoning: RL-1 (Residential Low-1) 3. Applicant: Public Works, Brian Wiltshire, Project Manager 4. Owner: City of Boulder STAFF RECOMMENDATION Staff recommends that the Landmarks Board adopt the following motion: I move that the Landmarks Board approve the application for the installation of pedestrian lighting as shown on plans and specifications dated May 10, 2018, finding that, if installed pursuant to the conditions below, the pedestrian lighting will meet the standards for issuance of a Landmark Alteration Certificate in Section 9-11-18, B.R.C. 1981, and will be consistent with the General Design Guidelines, the Chautauqua Park Historic District Design Guidelines and the Chautauqua Park Historic District Lighting Design Guidelines, and adopt the staff memorandum dated June 6, 2018 as the findings of the Board. Agenda Item #6A Page 2 CONDITIONS OF APPROVAL 1. The applicant shall be responsible for installation of the lighting in compliance with the approved plans dated May 10, 2018, except as modified by these conditions of approval. 2. Prior to submitting a building permit application and receiving final issuance of a Landmark Alteration Certificate, the applicant shall submit details confirming the pedestrian light poles are made of real wood, not a wood composite. 3. Prior to submitting a building permit application and receiving final issuance of the Landmark Alteration Certificate, the applicant shall submit design details as required above that shall be reviewed and approved by the Landmarks design review committee (Ldrc) prior to the issuance of a building permit. The applicant shall demonstrate that the design details are in compliance with the intent of this approval and the General Design Guidelines, the Chautauqua Park Historic District Design Guidelines and the Chautauqua Park Historic District Lighting Design Guidelines. 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. Agenda Item #6A Page 3 Figure 1. Map of the Chautauqua Park Historic District. 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. Figure 2. Chautauqua grounds looking northwest, c. 1900-1910. Denver Public Library. 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 1 Colorado Chautauqua. National Historic Landmark Nomination, 2005. Agenda Item #6A Page 6 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. Figure 3. Shelter House and King’s Gate, c1925-1940 (left) and 2018 (right). 2 Chautauqua Lighting Design Guidelines, p. 24. 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 3 Colorado Chautauqua Association. Chautauqua Landscape Assessment. 2014. https://www.chautauqua.com/wp- content/uploads/2014/09/Chautauqua_Landscape_Assessment_2004.pdf 4 Chautauqua Park Historic District Design Guidelines. City of Boulder, 2018, p. 11-16. Agenda Item #6A Page 8 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.’” Figure 5. View of a group of men and women in front of the Ticket Office, 1898-1902. Light fixture visible at left side of photo. Carnegie Branch Library for Local History. 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. Figure 6. Site Plan showing existing (dashed line) and proposed (solid line) lighting fixture locations.

Fixture Cable Agenda Item #6A Page 14 CRITERIA FOR THE BOARD’S DECISION Subsections 9-11-18(b) and (c), B.R.C. 1981, set forth the standards the Landmarks Board must apply when reviewing a request for a Landmark Alteration Certificate. (b) Neither the Landmarks Board nor the City Council shall approve a Landmark Alteration Certificate unless it meets the following conditions: (1) The proposed work preserves, enhances, or restores and does not damage or destroy the exterior architectural features of the landmark or the subject property within an historic district; (2) The proposed work does not adversely affect the special character or special historic, architectural, or aesthetic interest or value of the landmark and its site or the district; (3) The architectural style, arrangement, texture, color, arrangement of color, and materials used on existing and proposed constructions are compatible with the character of the existing landmark and its site or the historic district; (4) With respect to a proposal to demolish a building in an historic district, the proposed new construction to replace the building meets the requirements of paragraphs (b)(2) and (3) above. (c) In determining whether to approve a landmark alteration certificate, the Landmarks Board shall consider the economic feasibility of alternatives, incorporation of energy-efficient design, and enhanced access for the disabled. ANALYSIS 1. Does the proposed application preserve, enhance, or restore, and not damage or destroy the exterior architectural features of the landmark or the subject property within a historic district? Staff considers that provided the conditions listed are met, the proposal for installation of the proposed lighting fixtures will not damage or destroy the character of the Chautauqua Park Historic District. 2. Does the proposed application adversely affect the special character or special historic, architectural, or aesthetic interest or value of the district? Provided the listed conditions are met, staff does not consider that the proposed installation of lighting in the Chautauqua Park will adversely affect the historic, Agenda Item #6A Page 15 architectural, or environmental significance of the historic district. 3. Is the architectural style, arrangement, texture, color, arrangement of color, and materials used on existing and proposed structures compatible with the character of the historic district? Staff considers that the proposal will be compatible with the historic character of the Chautauqua Park Historic District. 4. Does the application incorporate energy-efficient design and enhanced access for the disabled? The lighting fixtures were selected to be energy-efficient and to enhance pedestrian access in the Chautauqua Park Historic District by lighting paths that are frequently used by visitors, employees, neighbors and volunteers. 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. Agenda Item #6A Page 18 Chautauqua Park Historic District Lighting Design Guidelines – Analysis 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 Yes Agenda Item #6A Page 19 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 1.7 Scale and size of luminaires should not overwhelm the historic setting and should be compatible with the historic buildings and landscape. 1.7.1 Where possible, integrate lighting into the historic setting through low mounting-level light fixtures such as directional lights mounted in unobtrusive locations, pedestrian scale pole mounted luminaires, and streetlights. Bollards may be appropriate in unobtrusive locations, such as the perimeter of parks, but are discouraged along pathways. The proposal includes directional lights mounted in unobtrusive locations and pedestrian scale (16’ poles, bottom of the hood measuring at 14’ from the ground). Yes 1.7.2 Provide a consistency of scale and size for luminaires throughout each lighting area, appropriate to the scale of the individual building or landscape. Staff considers the proposed scale to be consistent throughout each lighting area and appropriately scaled to the landscape. Yes 1.8 Lighting qualities should respect the historic character of the district. 1.8.1 Light color should be warm and evoke the camp-like character of the historic district. • In all areas except the residential area, light sources should have a CCT of 3000K CRI; light sources in residential areas should have a CCT of 2700K CRI. • Across lit areas, create a balance of lighting that eliminates glare. • Luminaires under 900 lumen output should have a maximum B-U-G rating of G=0; Luminaires over 900 lumen output should have a maximum B-U-G rating of G=1. Light is proposed to be 3000K, which is a warm light. Yes 1.9 Luminaires should be easy to maintain and energy efficient. 1.9.2 Luminaires should have modular lighting components for replacement if failure occurs. Fixtures are modular and can be replaced if failure occurs. Yes The following guidelines apply to the proposed lighting fixtures in the parking lot. 4.0 Parking/Circulation Parking/Vehicular Circulation includes areas along major roadways and parking areas utilized primarily by visitors and staff during evening hours. These include the parking areas at the tennis court and Academic Hall, major intersections, and 12th Street between the picnic shelter and tennis court parking. This does not include parking for cottages or on-street parking. Where appropriate, lighting in parking areas should be adequate for navigation and to address safety and security concerns. Agenda Item #6A Page 22 Guideline Analysis Conforms? 4.1 Lighting in parking/vehicular areas may be appropriate to provide a sense of security and navigation. 4.1.2 Lighting may be appropriate in the following areas: • Select street intersections where conflicts are identified. • Pick-up/drop-off locations. • Vehicular entrances at Kinnikinic and 12th Street. • Parking areas at the Academic Hall; Ranger Cottage; 12th Street; and Tennis Court. Three lighting fixtures are proposed at the Tennis Court Parking Lot. Yes 4.2 If appropriate, parking areas should be lit with low intensity lighting and have no spill light outside of the parking area. 4.2.1 Maximum average should be approximately 0.2 footcandles with 20:1 uniformity. Use house side shields to minimize spill light. Lighting is designed to have no spill outside of the parking area. Yes 4.3 Lighting in parking areas should be managed according to the varied activities occurring within the historic district. 4.3.1 Parking area luminaires should be 3000K CRI, Type III distribution and employ a House Side Shield (HSS) to minimize spill light. Maximum B-U-G rating of B1-U0- G1 (without HSS). The luminaire should be installed plumb for Dark Sky Friendly operation with the distribution aligned with the parking area, and no higher than 20’. The parking lot fixtures meet these specifications. Yes 4.3.2 Parking lot lighting controls should utilize a programmable control system to preset the high and low output levels based on time of night and occasion with motion sensors to trigger the lights between the preset levels. The lighting will be turned on an hour before dusk, dimmed to 50% at 2 am, and then turned off at dawn. Sensors are not proposed as part of the light controls. Maybe Agenda Item #6A Page 23 The following guidelines apply to the proposed lighting fixtures along the path from the King’s Gate Shelter House and the Tennis Court Parking Lot. 5.0 Primary Pedestrian Primary pedestrian routes are major pedestrian circulation routes, sidewalks, and pedestrian crossings. These include the route between the Auditorium and King’s Gate; the route from the Dining Hall to the Tennis Court parking; King’s Gate; the Arbor; the south side of Clematis Drive; and along Kinnikinic from Clematis to the Baseline entrance. Lighting along primary pedestrian routes should be visually comfortable, without glare, and should provide lighting for navigation and to illuminate tripping hazards. The use of wayfinding lighting may be appropriate to direct pedestrians to their destination with intermittent pools of light and beginning and ending points along paths. Guideline Analysis Conforms? 5.1 Where appropriate, provide pedestrian lighting for navigation, to guide users to destinations. 5.1.1 Lighting should be visually comfortable without glare. Lighting designed to be visually comfortable without glare. Yes 5.1.2 Lighting should only occur at intervals sufficient enough to provide adequate navigation, to see from one light location to another. Proposed lighting is located at intervals to provide navigation along the path, while still creating a balanced level of light along the path. Yes 5.1.3 Where appropriate, paths may be illuminated with pedestrian scale luminaires. Pole mounted luminaires should be Type II Distribution, Dark Sky Friendly, either with a Full Cutoff classification or a B-U-G rating of U=0, and 3000K CRI. The parking lot fixtures meet these specifications. Yes 5.2 Operation of pedestrian lighting should be programmed to meet operational needs, based upon business and event hours. 5.2 See above The lighting will be turned on an hour before dusk, dimmed to 50% at 2 am, and then turned off at dawn. Yes 5.3 Sensitively designed lighting may be appropriate in these areas: • Interior of the Arbor and King’s Gate trolley stop, taking care to protect historic material and integrate fixtures to be minimally visible. • The pedestrian path between the Dining Hall, Auditorium and Tennis Court Parking area, and the stairs near the Tennis Court Parking area. • The pedestrian path from the Auditorium to King’s Gate. • Along Clematis Drive. 5.3 See above Lighting is proposed along the pedestrian path between the Dining Hall and Tennis Court Parking area and at the Interior of Yes Agenda Item #6A Page 24 the Arbor and King’s Gate shelter house/trolley stop. The lights at these structures will are designed to protect historic material and integrate fixtures to be minimally visible. 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.

Agenda Item #6A Page 35 Attachment B: Applicant Materials Attachment B-1: Project Narrative 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 Reference Attachments: Lighting Map, Lighting Detail, Chautauqua Pedestrian Light Rendering, Pedestrian Wood Pole Specification Sheet, Pedestrian Wood Pole and Metal Base Stain and Finish Sheet, Parking Metal Pole Specification Sheet, Type II Skirted Bell Specification Sheet, Type III Skirted Bell Hood Specification Sheet, Skirted Bell Hood Finish Sheet, Arbor Lighting Detail, Arbor Lighting Finish Specification Sheet, Arbor Lighting Installation Detail, Kings Gate Lighting Detail, Kings Gate Lighting Finish Specification Sheet, and Kings Gate Lighting Installation Detail which show the proposed pedestrian and parking light fixtures, the Arbor and Kings Gate light fixtures, the methods of installation, and locations of the lighting which meet the project purpose, budget and applicable regulations and design guidelines. 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.
