03/16/2004, BUS 5 - DOWNTOWN PEDESTRIAN LIGHT STANDARD
i counat �'"D� March 16,2004 j ac cn as Report N.A. s S" CITY OF SAN LU I S O B I S P O FROM: Michael D. McCluskey, Director of Public Works Prepared By: Bridget Fraser, Associate Engineer SUBJECT: DOWNTOWN PEDESTRIAN LIGHT STANDARD CAO RECOMMENDATION Adopt a resolution: 1. approving a downtown pedestrian-scale pole and light fixture as recommended by the Architectural Review Commission (ARC); and 2. establishing an initial Downtown Pedestrian Lighting District as co-terminus with the boundaries of the downtown commercial core. DISCUSSION Summary As part of the City's 2001-03 Financial Plan, Council identified pedestrian-scale street lighting in the historic downtown as an "Other Council Objective." The emphasis focused on improving pedestrian visibility and enhancing the historical and architectural character of the downtown. The first stage of the downtown lighting program - selection of a pedestrian-scale standard pole and light - has been accomplished and is recommended for adoption by Council. Additionally, staff is recommending that Council adopt a downtown pedestrian lighting district. Having the district and light standard adopted now will allow for some installations to occur-as opportunities arise (such as the Copeland's or Garden Street Makeover Projects). Staff will continue to work on the subsequent phases of the plan as resources allow and return to Council at a future date to present recommendations for spacing and light levels, cost estimates, and funding alternatives. Background The idea of pedestrian-scale street lighting in downtown is not recent. Seeds were planted as far back as 1982 where as part of an urban design study for downtown, Council endorsed the idea of a two-tiered street light system: tall poles at intersections and shorter pedestrian-scale poles mid- block. Due to costs, the pedestrian lights were never installed. The issue surfaced several times since then as groups such .as the Chamber of Commerce and the Downtown Association expressed their support for the idea, with the Downtown Association offering to organize a sponsorship program similar to its commemorative bench program to help fund the program and increase private interest. Subsequently, the City Council included the downtown pedestrian lighting plan as an "Other Council Objective" in its 2001-03 Financial Plan, directing staff to establish a historic downtown pedestrian lighting plan in cooperation with the Downtown Downtown Pedestrian Light Standard Page 2 Association. Public Works and Planning staff began work on selection of the light pole and luminaire during the summer of 2002. Design Principle/Selection Criteria Searching for a pedestrian light standard for downtown was not an easy task. Not only were there hundreds of designs and manufacturers to choose from, there was also a need to balance the City's historic preservation objectives with the desire to take advantage of modern materials and technology. The key was to develop a selection criteria that would lead us to find a style that we could call our own. Planning, engineering and maintenance staff developed the following criteria to aid in selecting a standard: 1. Vintage-style luminaire and pole 2. Ease of maintenance and installation ry 3. Durability and quality of materials and workmanship 4. Fixture rated as at least a "semi-cutoff'fixture 5. Flexibility to change lamp types and ballasts 6. Vandal resistant I 7. Offers options and variations such as multi-heads, wall mounts, banner arias and flower basket arms, etc. Most of the "vintage" style lights used today for pedestrian and street , lighting are replicas of gas lamps used throughout history. San.Luis Obispo is fortunate to have used gas lamps to the early 1900s to 1940s original Gas Lamp v- (Attachment 1). This allows us to bring back. a near look-alike of our 1914 original gas lamp rather than "borrow" Courtesy of SLO Historical a design from another city. society Additionally, incorporating today's modern materials and lighting -----^� technology in the design allows us the best of both worlds — historic iL vintage styling that is more durable and is sensitive to the present day oj, issues of light pollution, glare, energy efficiency and maintenance. A _ manufacturer was selected that best met this criteria. From there a selection of styles and options were identified and presented to the Culturalg Heritage Committee (CHC) at their July 22, 2002 meeting. One fixture ! was preferred due to its more traditional styling. However, the CHC ! postponed making a final recommendation until details like globe type, j paint finish, lighting cutoff, and lighting color/intensity could be viewed on an actual working sample. Staff continued to work with the manufacturer to refine the design, resulting in a more functional and historically accurate ^= design. Working samples of the light fixture and pole were obtained and Proposed Pedestrian Light used in a demonstration project as discussed below. Located ar M Higuera Pedestrian Light Committee During the fall of 2002, a committee of representatives from the Downtown Association, Chamber of Commerce, City Administration, Planning, and Public Works departments was formed to discuss and evaluate the fixture and lighting options. The group provided a broad cross-section of expertise and viewpoints ranging from maintenance and technical to aesthetics S' of Downtown Pedestrian Lig.,t Standard Page 3 and business perspectives. The committee also organized and conducted on-site lighting demonstrations during the public review process. Public Review Process During January and February 2003, an on-site demonstration was organized to further evaluate various lighting elements such as lamp color, wattage, globe type and pole height. The site demonstration gave the various advisory bodies (CHC/ARC) a chance to assess the fixtures in a "real" setting prior to the public review meetings. During this demonstration period staff also took the opportunity to gather input from the public at three Thursday Night Farmer's Markets. Advisory bodies and the public were given a chance to compare Metal Halide (white) vs. High Pressure Sodium (yellow) lamps, opaque vs. semi-translucent globes, and 10 foot vs. 12 foot pole heights. The demonstration poles were obtained in the manufacture's dark forest green - the closest match to the Council approved forest green. (Please note that the demonstration fixture outfitted with the recommended lamp, globe and pole at 728 Higuera is operational and available for Council's review.) The CHC, at their meeting of February 24, 2003, reviewed the proposed light fixture and the lanrp/globe options. From this review the CHC recommended that the ARC approve the round semi-translucent globe with a 70W Metal Halide bulb on a textured finish 12' high tapered and fluted pole (See Attachments 2 & 3 for light standard and Attachment 4 for CHC minutes). At their March 17, 2003 meeting, the ARC approved the CHC recommended light fixture, with a condition that the pole color be modified to better match the City's adopted dark green and that the final lighting plan be returned for their approval. A copy of the ARC agenda report and minutes are attached (Attachment 5 and 6). The ARC also recommended that a staggered spacing of 4 poles per side per block be used as a starting point for evaluating of light levels and spacing (Attachment 7). Evaluation of the Various Lighting Elements There are many elements to consider in determining a pedestrian lighting system — height, spacing, uniformity and light levels, globes styles, lamp types, materials, etc — particularly in a downtown environment where emphasis is placed creating ambiance and atmosphere not just putting light on the ground. Some of these elements play against each other, making it difficult to select "the"perfect design. For example, to achieve the best light levels and uniformity on the ground you need more and brighter lights. This is costly, can clutter sidewalks and may cause more discomfort to pedestrians due to the brightness. In turn, you can achieve better uniformity with fewer lights if they are taller, but taller lights will interfere with the tree canopy and/or shine into second story rooms. These are just a few problems that were faced. The recommended light fixture is based on an attempt to reach the best "balance" of all the elements. A discussion of the various elements addressed in selecting the pole and fixture can be found in the attached ARC agenda report (Attachment 5). S- 3 Downtown Pedestrian Ligut Standard - Page 4 Proposed Boundaries of Downtown Pedestrian Lighting District The direction in the 2001-03 Financial Plan was to establish a "historic downtown pedestrian lighting plan in cooperation with the Downtown Association." Staff interprets this as the lighting area being, at least initially, congruent with the downtown commercial core boundaries (See Exhibit B of Attachment 8). This makes particular sense considering the .possibility that a portion of the funding for the lights may be through a Downtown Association (DA) administered sponsorship program similar to the commemorative bench program. However, consideration should be given to extending the downtown pedestrian lights outside of the downtown core boundary. There have been discussions and comments regarding the lighting being used as a "gateway" feature into the downtown; lining Monterey Street to its north boundary and Higuera and Marsh Streets south to the Marsh Street/Highway 101 on/off ramps. The Mission Sidewalk District most resembles this expanded area and could be used as the pedestrian lighting boundary if Council chooses. Staff recommends initially establishing the lighting boundary as the downtown commercial core area. Expansion into other areas such as the Mission Sidewalk District can be addressed a future date. Where are we headed? Once a standard and boundary is adopted, subsequent phases of the program can be initiated in the following manner: 1) Evaluate current street light system—Should new pedestrian lights replace the current street light system or supplement the current system? (Currently staff recommendation is leaning towards leaving the tall "cobra head" lights installed at the intersections; removing the mid-block cobra heads and replacing them with pedestrian lights. However, more in-depth research is required before a final recommendation can be given.) 2) Determine appropriate spacing and light levels - How many poles per block and what level of brightness is appropriate to provide adequate security without being overly bright or overly cluttered. (ARC has given us a recommended spacing as a place to start this evaluation. Light levels and coverage will be evaluated using this initial spacing and adjusted as needed.) 3) Develop a plan for prioritizing location and placement. (Which areas of downtown would benefit the most from better lighting?) 4) Identify the extent of the existing underground conduits and electrical services. 5) Develop cost estimates. 6) Evaluate funding alternatives and secure funding. 7) Develop a policy for installations. (For example, install 1 or 2 lights at a time or complete 1 or 2 blocks at a time.) 8) Begin installations. Staff concurs with ARC Commissioner Root's (See ARC Minutes) recommendation to move forward in "baby steps" and proposes that one block of "test" lights be installed based on the initial spacing and light levels determined in Step 1. The installation can then be reevaluated before committing to large quantities of installations. Adjustments can easily be made—small or large- without a significant loss of investment. Two possible locations appropriate for "test" �r Downtown Pedestrian Ligin.Standard Page 5 installations include the block of Garden Street between Marsh and Higuera (subject to funding) and the block of Higuera between Broad and Chorro Streets. This block is very dark and could greatly benefit from the installation of lights. CONCURRENCES ■ The Cultural Heritage Committee reviewed and approved the downtown pedestrian light standard at its February 24, 2003 meeting. ■ The Architectural Review Commission reviewed and approved the downtown pedestrian light standard at its March 17, 2003 meeting.. ■ The Downtown Association has been involved in the evaluation and selection process and is committed to assist the program through sponsorships. FISCAL IMPACT There is no direct fiscal impact in adopting the standard. The adoption will provide a uniform fixture to those wishing to install vintage lighting. Installations would compete with other projects through the budget process. ATTACHMENTS 1. Historic photos of old gas lamps 2. Photos of recommended light fixture 3. Diawings of light fixture 4.

PUBLIC COMMENTS: Mary Beth Schroeder, 2085 Wilding Lane, objected to the proposed relocation. of the historic Pinho house. MINUTES: On a motion by Committee member Crotser, seconded by Committee member Whittlesey, the minutes of the January 27, 2003 meeting were approved as submitted on a 6-0 vote (Committee member McDonald absent). PUBLIC HEARING ITEMS: (Items 1 and 3 through 6 omitted) 2. Downtown Historic District. ARC 193-02. Review results of Historic Street Light Demonstration and recommend lighting globe and bulb types. City of San Luis Obispo, Applicant. Jeff Hook presented the staff report and displayed working samples of the two types of globes and light bulbs being considered for Downtown. He discussed the results of the public survey done over six weeks and explained that public preference was about evenly split between High Pressure Sodium and Metal Halide lamps, and between the POND (partially clear) and the Opaque (white) globes. After discussion, and on a motion by Committee member McMasters, seconded by Committee member Crotser, the Committee voted 7-0 to determine that the round POND globe, dark green textured pole, and 70-watt Metal Halide bulb are compatible with the Downtown Historic District and with the City's Historic Preservation Program Guidelines, and referred the project to the Architectural Review Commission with a recommendation to approve the historic pedestrian street lighting with the features noted. Committee members reiterated that the round globe, and not the acorn shaped globe, was preferred because it most closely resembled the City's original gas street lamps. 1 �) Attachment 5 EXCERPT OF.

Downtown. ARC 193-02; Review of a downtown historic street lighting program; City of San Luis Obispo Public Works Department, applicant. Associate Planner Michael Cod ron presented the staff report recommending approval of the light standard, based on findings and subject to conditions of approval. Bridget Fraser, Associate Engineer, gave a brief description on the many things to consider on a light system, such as height, spacing, lamp types, and maintenance cost. She explained that their recommendation for the downtown light standard is based on an attempt to reach the best balance of all the elements. She explained the importance of using a design that resembles the old fixtures. She offered a few examples of lamps and lamp poles to choose from. Commr. Smith questioned the preference of aluminum versus cast iron. Ms. Fraser replied staff prefers the aluminum due to its strength, durability, lightness and has the look of cast iron. Chairperson Stevenson questioned the location for these lights. Ms. Fraser replied that it is not definite, but would most likely start with the Downtown Association area. Chairperson Stevenson mentioned he would eventually like to see lighting coming in off the freeway along Marsh when the budget allows, feeling it would be a great entry feature. ARC Minutes _ Attachment 5 March 17, 2003 Page 2 Commr. Lopes noted that the color is lighter than the City's designated color and wondered what is the next darker shade of green. Ms. Fraser replied this is the darkest green available from the manufacturer's standard choices, but noted they could get any custom color for an additional cost. Commr. Howard asked how the applicant felt about the scale and spacing of these poles. Dave Relyea, Prudential Lighting, explained they are trying to minimize the number of Poles. PUBLIC COMMENTS: Dr. Bob McQuade, Light Designer, commented on how they came up with such a unique design that fits San Luis Obispo. Gary Wong, SLO, asked who presently maintains the streetlights. Ms. Fraser replied the City maintains the streetlights. There were no further comments made by the public. COMMISSION COMMENTS: Commr. Howard moved to approve the downtown pedestrian light standards as Proposed by staff; recommended a spacing of four light poles per block per side and to come back to the ARC for review and approval of a final lighting plan. Seconded. by Vice-Chair Schultz. Commr. Root expressed concerns about the lighting that is being recommended and felt the light is to create an atmosphere. He recommended they be cautious of the lumens they are putting on the street and suggested they take baby steps. Chairperson Stevenson asked if they could suggest that the wattage be reduced. Ms. Fraser responded yes, and explained they are just asking for a recommendation on spacing, noting they will come back.to the ARC with a definite spacing and the wattage of luminaire that would be used. Commr. Lopes requested a condition that the color be as approximate as possible. The motion maker and seconder accepted the request for a condition. Chairperson Stevenson requested they add on to that condition that an alternative that includes a.banner arm attachment for some of the boles. The motion maker and seconder accepted the request to add on to the condition. ARC Minutes Attachment 5 March 17, 2003 Page 3 Ms. Fraser replied this could be done. AYES: Commrs.

SUMMARY RECOMMENDATION: Approve the light standard,based on findings and subject to conditions of approval. BACKGROUND: Situation As part of the City's 2001-03 Financial Plan, Council identified pedestrian scale street lighting in the historic downtown as an"important city objective." The emphasis focused on improving pedestrian visibility and enhancing the historical and architectural character of the downtown. The first stage of the downtown lighting program is underway - selection of a standard pole and light for eventual adoption by Council. Once a standard is adopted, the subsequent phases of the program will include 1) creating a plan for location and placement of the pedestrian lights, 2) identifying the extent of the existing underground conduits and electrical services, 3) developing a policy for installation and, 4)evaluating funding alteratives. Data Summary Address: Downtown Applicant: City of San Luis Obispo Representative: Bridget Fraser, Associate Engineer Zoning: C-C-H (Central Commercial—Downtown Historic District) General Plan: General Retail Environmental: Categorically Exempt(CEQA Guidelines, Section 15303) Site Description Exact locations for the new light standards have not yet been identified. The project boundary for the new lighting has not been established at this point. The direction in the Financial Plan was for lighting in the "historic downtown." Using the Downtown Association boundary as an initial project area has been discussed because potential funding for the lights may be through a program similar to the "adopt-a-bench" program 3�1 .TTACHMENT 6 ARC 193-02 (Downto,* .ighting) Page 2 of 7 administered by the Downtown Association. Other existing boundaries that could be used are the Downtown Historic District, Central Commercial Zoning District, or the Mission Sidewalk District. The project area may expand in the future depending on financing. Project Description The proposed light standard is reminiscent of the historic gas lamps that were used throughout the City in the early 1900s through 1940s. The pole, globe, and fixture closely match the style of gas lamps seen in historic photos, while the bulb, ballast, and optic system will fulfill modern lighting needs(Attachment 1). A The cast aluminum pole is fluted and tapered, 12' tall, and has a green textured finish. The polycarbonate globe has a partially obscured non-diffused (POND) finish which is transparent. Above the globe is a green top hat with a decorative finial. The light source is a 50, 70 or 100 watt (depends on light level and spacing) frosted Metal Halide (MH)bulb. Similar light standards with a 70-watt bulb are currently installed at the Mitchell Park playground. Once a light standard is approved a lighting plan will be developed and will return to the ARC for approval if necessary. Proposed Light Standard Public Survey A committee of representatives from the Chamber of Commerce, Downtown Association, and the City Administration, Planning, and Public Works Departments was formed to discuss the fixture and lighting options and organize lighting demonstrations. Samples of the light fixture and pole were installed downtown for the demonstration project. In the demonstration, opaque (white) vs. partially obscured non-diffusing (POND) globes and High Pressure Sodium (HPS) vs. Metal Halide (MH) bulbs were compared. Patrons of the Thursday night Farmers Market were surveyed to determine which globe and bulb combination was aesthetically preferred. Opinions were also collected through an online survey. A description of the survey is contained in the memo that was distributed in January (Attachment 2) The results of the survey indicate there was not a strong preference for any particular combination. The specific survey results show that the opaque globe was preferred when the HPS bulb is installed and the Pond globe is preferred with the MH bulb. When comparing the two light bulbs, when each pole had a POND globe, the BPS bulb had the majority of votes. The results show that there is a slight preference for the HPS bulb and if it is used then the opaque globe is preferred (Attachment 2). The differences in �Ia ARC 193-02 (Downtc. ` ighting) - ATTACHMENT 6 Page 3 of 7 opinions that were collected about the globes and bulbs is slight and do not reflect a strong preference either way. EVALUATION: The criteria used in choosing a light standard included; high aesthetic quality, compatibility with the historic character of downtown, low cost, high lighting quality, low levels of light pollution,ease of maintenance and flexibility. Aesthetic quality The proposed light standard style is decorative and interesting but simply designed. The light standard is made of high quality materials and the color, green, will match the standard color of the sidewalk benches. The style is consistent with the community's expectations of quality and character in architecture and urban design. Compatibility with the Historic Character of Downtown The style of the proposed light standard is very similar to the old gas lamps of the early 1900's seen in historic photographs (Attachment 4). Although the top hat is a different shape than the gas vent on the historic lamps, it was chosen for its functional ability to prevent light pollution which will be discussed in the light pollution section. The proposed 12' pole will illuminate a larger area of the sidewalk than a 10' pole, therefore fewer lights are necessary. Photo simulations show that the 12' pole is not so high that it will shine into second story windows or get lost in the existing trees (Attachment 5). A shorter pole could put the globe within reach of potential vandals. CHC Review—On February 24, 2003,the CHC reviewed the proposed light standard and recommended that the ARC approve the light with the round POND globe, a 70W MH bulb,and textured finish on the pole (Attachment 6). Cost Comparisons A detailed cost analysis is in the attached cost comparison,prepared by Bridget Fraser (Attachment 7). Taking into consideration the lamp cost and the energy efficiency of the lamp and globe, the MH lamp is approximately $19/yr less expensive than the HPS and the POND globe is $9/yr less expensive than the opaque. Light Quality Glare —Glare is difficult to precisely define and is a response that varies from individual to individual. This is demonstrated by comments collected during the survey where some people commented that the POND globe has more glare and others said the opaque globe has more glare. Glare is divided into two classifications, disability glare and discomfort glare. Disability glare occurs when the bright light close to the line of sight keeps a IS- 3�3 _ATTACHMENT 6 ARC 193-02 (Downto ,: ighting) Page 4 of 7 person from seeing adequately. Discomfort glare doesn't necessarily prevent a person from seeing but is bothersome. Glare can be experienced differently by pedestrians and drivers. A pedestrian would be more sensitive to a view of a bright lamp and uneven lighting along the street where a driver would be affected by glare from light at high angles that isn't shielded by the roof of their car. Therefore glare is a factor of light level, lamp position, lighting uniformity, and the amount of light cutoff from the fixture. The 70 watt bulb provides a light level that is adequate for safety but not excessive and the semi-cutoff fixture is a balance between directing the light downward instead of into the eyes of drivers and pedestrians and maximizing lighting uniformity. Light Effectiveness—As described in the cost comparison, recent research shows that the color output of light sources used for lighting has a significant effect on how well we see at night. In typical low lighting conditions, the "seeability" of the white light produced by the MH lamp is greater than the yellow/orange light of the BPS lamp. Although the lumen output of High Pressure Sodium (HPS) lamps is higher, , most of the light is yellow rather than blue,therefore the effective lumens are reduced. (Attachment 8). Color Rendering — In general the Color Rendering Index (CRI) is an indication of a lamps ability to show individual colors. The higher the CRI, the better the different colors will show. On a scale from 1-100, natural daylight has a CRI of 100, BPS has a CRI of around 22 and MH has a CRI of 75-85. Thus MH is better showing colors more naturally. Lighting standards used today assume that all lumens are equal without considering that the eye sensitivity to the type of lumen output. It is important to consider the quality of light as well as the amount of light from various light sources. Light Pollution Light pollution is light which is directed into the sky, adding to the glow that surrounds urban areas, and reducing the ability to view the nighttime sky. Light into the sky can come directly from the light fixture or be reflected off of the ground. The term cutoff is used to describe the optical performance of a light fixture. There are four classifications of cutoff, full-cutoff, cutoff, semi-cutoff, and non-cutoff (Attachment 9). The classification is determined by the amount of light that is directed at or above a horizontal plane at the bottom of the shield. The proposed fixture is semi-cutoff with a maximum of 5%of the lumen output going above the horizontal plane. The semi-cutoff fixture allows for wider spacing between poles than the full-cutoff or cutoff fixtures, therefore less lights are necessary for the same lighting level. In order to maintain even lighting uniformity along the sidewalk, fewer semi-cutoff lights are required than full-cutoff or cutoff. 31� -ATTACHMENT 6 ARC 193-02 (Downto._ , !Lighting) Page 5 of 7 Flexibility Changing lamps and ballasts—The proposed lights allow for easy toolless replacement of the lamps and ballasts. The globe is removed by turning it and lifting it off the pole. Then the lamp and ballast can be removed with a twist. Ballasts are connected by a plug.The fixture is maintenance friendly and is compatible with other lamp/ballast types which allows the flexibility to change to other lamp types.. Accessories — The proposed light standard can be modified for various functions. The same pole and globe can be used in a double arm version or the globe can be wall mounted with a single arm. The pole can also accommodate hanging baskets or banners. These features are not a part of the current project but the flexibility of the standard is important to allow for other applications and functions in the future. Lighting Plan A lighting plan will be developed based on the approved light standard. The goal of the plan is for uniform pedestrian oriented lighting without detracting from the current character of the downtown. The spacing and number of lights is an important part of the plan since too many would clutter the sidewalks and take the focus away from the buildings. Staff would like the ARC's recommendation on light spacing and/or how many per block may be aesthetically appropriate. Since spacing is a function of lamp wattage, light levels, and uniformity, this would be a general recommendation or a target, to help staff develop a lighting plan. A condition of approval that the lighting plan return to the ARC for approval is included but may be removed if the ARC feels that it is not necessary. Public Comments In addition to the comments received as part of the public survey, some were sent by email directly to staff(Attachment 10). A letter was also received from Robert McQuade. in support of MH bulbs(Attachment 11). Compliance With General.Plan LU 4.5 Walking Environment Downtown should provide safe, exciting places for walking and pleasant places for sitting... The installation of the lighting will provide asafer walking environment downtown. EC 13.9 Lighting Sources The City wil replace incandescent and fluorescent outdoor lighting with more efficient sources, such as sodium vapor illuminators. 3)5 5 r I"I ARC 193-02 (Downtov L ighting) ^ TTACHMENT 6 Page 6 of 7 The MH bulbs are more efficient than incandescent and fluorescent bulbs because of its higher direct lumen/watt efficiency than incandescent and better optical performance (control of light) than fluorescent. When considering quality lighting and appropriate light levels the MH lamps are more efficient than the HPS. The MH is also more appropriate for this application because of its higher color rendering abilities. Compliance With Community Design Guidelines The project meets the objective of the Design Guidelines to promote design that is architecturally distinctive, at the pedestrian scale, and integrated with the natural environment. The lighting style is consistent with the gas lamps that used to be in downtown SLO and are unique to this community. The lights will primarily function to light the sidewalk and'provide a safer environment for pedestrians. The MH bulbs will allow an observer to see the true colors of the trees, while the semi-cutoff fixture will limit the amount of light that is directed upwards and impacting views of the night sky. 6.1(C). Lighting(Attachment 12) Light will be directed downward by the top hat and optical system. The POND globe, with better optical performance than the opaque globe, allows the light to be directed towards the sidewalk where it is needed. For this application increased numbers of lights at lower intensity would conflict with the goal of compatibility with the downtown environment. Increasing the number of light poles would crowd the sidewalks and detract the focus from the architecture of the buildings. The MH lamp will enhance the building architecture, landscaping, and merchandise displays in the downtown because it has a high color rendering, making things look more like they would in daylight. The light standard style compliments downtown architecture and its durability will ensure that the style and quality are long lasting. RECOMMENDATION: Approve the downtown pedestrian light standard, give recommendations on spacing, and give direction on whether the final lighting plan will need ARC approval. Approval of the project is based on the following findings and conditions of approval: Findings: 1. The light standard is consistent with the Community Design Guidelines and the General Plan. The lighting is reminiscent of the gas lamps that lit the downtown in the past, pedestrian oriented, and will minimize impacts to the natural environment. The project will also increase pedestrian safety downtown. �- t4 TTACHMENT 6 ARC 193-02 (Downto,..__Lighting) Page 7 of 7 2. The project is compatible with the Downtown Historic District and with the City's Historic Preservation Program Guidelines because the light standard is closely matched with the style of the historic gas lamps that lit downtown SLO in the early 1900's and will not impact the historic character of the downtown. 3. The project is categorically exempt from environmental review (CEQA Guidelines, Section 15303). Conditions: I. The final lighting plan shall returnfor ARC review and approval prior to the installation of the lights. Attached: Attachment 1: Proposed light standard.

City staff, under Bridget Fraser's (Public Works) lead and in cooperation with the Chamber of Commerce and the Downtown Association, is in the process of developing such a program. At its July 22, 2002 meeting, the Cultural Heritage Committee (CHC) endorsed a light pole and fixture design. This standard combines the advantages of contemporary optics and ease of maintenance with historic styling that recalls the City's early gas street lamps. Committee members postponed making a recommendation on details like globe type, textured v. smooth paint finish, lighting cutoff, and lighting color/intensity until sample light standards could be installed downtown. Two samples of the CHC preferred light standards with different globes and lamps will be set up on Higuera Street, between Broad and Garden Streets. The demonstration, starting the evening of January 13" and continuing through February 24`x, will allow the City's advisory bodies and the public to compare the visual effects of High Pressure Sodium (HPS) or Metal Halide (MH) lamps, and partially obscured (Pond) or opaque globes. Approximately every two weeks, the demonstration will be changed so that different combinations of globes and lamps can be compared. The demonstration schedule will be as follows: Light 1 Light 2 Jan 13-Jan 26 HPS HPS Pond Opaque Jan 27-Feb 9 MH MH Pond Opaque Feb 10-Feb 24 HPS MH Preferred Globe Preferred Globe This schedule will allow Committee and Commission members, as well as the public,to view the options at night in the downtown setting. In addition, City and Downtown Association staff will have a table set up at the Farmer's Market on.January 16n, January 30', and February 13" to 3)9 - - Attachment 6 explain the demonstration and gather opinions from the public. Its important to note that there are many factors involved in selecting a new pedestrian light standard. This demo will serve to evaluate only the aesthetics of the light and pole itself using different lamps and globes as well as evaluate the light's effect on the surroundings (sidewalks, buildings, pedestrians, etc.). The solicited public opinions will be purely for determining which light looks best in our downtown. Other issues such as the lighting impacts, spacing, and efficiency will be addressed later and will eventually be added to the mix before coming up with a fmal recommendation. The CHC is scheduled to review the lighting again on February 24`x, and to forward its recommendation to the Architectural Review Commission (tentatively scheduled for March 17") for its review and recommendation to the Council.

Web survey comments: Feb 3,2003 "12'is too tall." Feb 6,2003 "I like the.pole in front of the Frog & Peach that has the MH/Pond illumination. The lamp is a frosted, 70 watt unit that looks good and renders colors well. I definitely do not want the RPS in our downtown at the pedestrian level. I am a lighting designer and here are important points .to consider. RPS has the lowest color rendering of all lamp types. It is a monochromatic light that only renders the orange/yellow/and muddy colors. We have a lot of greenery downtown and HPS doesn't render green'at all. HPS doesn't render merchandise in the stores and skin tone is rendered orange/gray. HPS isn't safe for pedestrians on sidewalks. It is difficult for drivers to distinguish objects under HPS. Pedestrians entering cross-walks or crossing Higuera between parked cars, outside of cross-walks will be in more danger of not being seen by oncoming cars under,HPS lighting. MH is a whiter light that renders colors reasonably well. It does a good job of bringing out the greens in foliage. Drivers and pedestrians have better visual acuity and seeing three-dimensional shapes under MH lighting. By using lower wattage, higher color rendering MH lamps, there will be no glare and the light will be a soft-white in appearance. The only place for HPS is in industrial and large roadway illumination. Our downtown deserves the best quality lighting that promotes safety, inviting, pleasant color rendering and beautifies our down town and historical architecture. Thanks for all of your outstanding effort and bringing these attractive fixtures to our city. Sincerely, Bob McQuade SLO resident of 25 years and lighting designer." Feb 13,2003 "Would strongly prefer a black pole over the green color selected." Feb 16,2003 "I love downtown. The only problem is my love hate relationship with the trees that have grown so large in the downtown area. Will the lamps be visible over the giant trees? It is too bad that the lamps cannot be installed in other areas of the City such as Monterey Street going north. A lot of tourists do use this part of the Community. The major area for the hospitality..industry such as hotels and restaurants, are on the northern part of the City, and numerous tourists come into this area from both North and South. I think the tourist customer is the one we want to impress since they bring in outside revenue. Anyway, just my recommendation." Feb 18,2003 "During the times I observed the lights, the fixtures on the Posie's side had too much glare." E-mail comments: Feb 13,2003 "I am writing to express my support of the Metal Halide light fixtures(as opposed to the High Pressure Sodium)recently installed on Higuera Street. The Metal Halide has a much better color rendition. High Pressure Sodium is what gives Santa Maria such a drab appearance at night. I also prefer the partially obscure globe as opposed to the opaque one. 3��3 Attachment g With regard to the globe,I believe an"acom" shape is more in keeping with an older downtown than a round globe more typical of the 60'2 and 70's. Thank you for your careful research. The selection of proper lighting will have a huge impact on the night time appearance of downtown and can attract people or drive them away.

Committee member McDonald arrived late. . Staff: Michael Codron and Jeff Hook, Associate Planners. PUBLIC COMMENTS: Mary Beth Schroeder, 2085 Wilding Lane, objected to the proposed relocation of the historic Pinho house. MINUTES: On a motion by Committee member Crotser, seconded by Committee member Whittlesey, the minutes of the January 27, 2003 meeting were approved as submitted on a 6-0 vote (Committee member McDonald absent). PUBLIC HEARING ITEMS: 1. 487 Marsh Street ARCPR 1-03. Plan revisions to The Mame.On Marsh Street residential care facility, including relocation of the historic Pinho House. Chris Skiff, Applicant. Committee member Whittlesey stepped down due to a possible conflict of interest. Michael Codron presented the staff report. He recapped past city actions and described proposed project changes. Chris Skiff, the applicant, explained the proposed changes and the reasons behind them. He questioned whether the Pinho house could still be considered historically significant given past architectural modifications and noted that Mr. Pinho lived in the house less than 40 years, the time period identified in the Historic Program Preservation Guidelines for establishing an historic association between a person and property. He felt the project would be improved if the Pinho house and the summer kitchen" were both moved to another site and restored together. Chairperson Wheeler opened the public hearing. Mary Beth Schroeder, 2085 WIding Lane, objected to the proposed relocation of the historic Pinho house and felt that moving the house would reduce its historic value to the community. She felt the City and the applicant should show respect for the property and its original owner. Diane Shirvem objected to changing the project after public hearings and comment had already taken place and a compromise reached. She felt that the proposed changes 3l� s� � Attachment 6 CHC Meeting Update, February 24, 2003 Page 2 raised new environmental issues that merited public scrutiny. Eric Myron, P.O. Box 16060, San Luis Obispo, 93406, said that he and his sister would like to move the house to their property at 463 Broad Street and that he would carefully restore the house and kitchen to their original architectural character. He cited his work experience in doing other similar projects. Michelle Stoutenbrough, 463 Branch Street, said that she intended to live in the house if it could be moved to her property and that she had great respect for the house and its historic significance. Hearing no further comment, Chairperson Wheeler closed the public hearing. Committee members did not support the proposed change and did not feel Mr. Skiff offered any new information to change the CHC's and the Council's previous actions on the property. Members noted that the Council's decision to preserve the historic Pinho house on its original site represented a carefully considered compromise and an excellent example of the type of "adaptive reuse" city policies encourage. They also noted the house's historic significance was due, in part, to its setting and location on Marsh Street, close to residences of other prominent San Luis Obispo citizens.. Based . on the Secretary of the lnterioes Standards for Rehabilitation, moving the building off site would adversely affect the integrity of the historical resource and is likely to trigger the requirement for additional environmental studies. They noted that the city attorney had determined the °40 year" timeframe was a guideline and not a strict requirement, and that Mr. Pinho had lived 33 years in the house and also had died there— enough of an association to clearly establish historic significance. s On a motion by Committee member Schrage, seconded by Committee member McMasters, the Committee voted 6-0 to recommend to the Architectural Review Commission that it deny the project based on the following findings: 1. The project is inconsistent with Finding #3 of Council Resolution No. 9295, which states that the location of the house and the detached building (formerty a kitchen and washroom for the residence) reflect the social status of the original builder and occupant and exhibit important information regarding the social context of the building and occupant because other significant individuals in the history of San Luis Obispo, including the Jack Family and the Higuera Family, lived on this part of Marsh Street. 2. The project is inconsistent with Finding #4 of Council Resolution No. 9295, which states the building's locations are significant because Marsh Street is important to the history and development of San Luis Obispo as one of its main thoroughfares and the historic residence is one of a few original residences remaining from the 19' century. 31n -OI Attachment 6 CHC Meeting Update, February 24, 2003 Page 3 3. Findings Nos. 5, 6, and 8 of Council Resolution No. 9295 establish Antonio Pinho as a long time Marsh Street resident, where he lived for 33 years with neighbors such as R. E. Jack and Thomas Higuera. Relocating the house would sever Pinho's connection with this historic section of Marsh Street. 4. The project is inconsistent with Finding #12 of Council Resolution No. 9295 because relocating the Pinho House will detract from the environmental design continuity of Marsh Street that is created by the Pinho House together with the Jack House (536 Marsh), Wi/kenson House (460 Marsh), and the Kaetzel House (547 Marsh). 5. The project is inconsistent with the City's Historical Preservation Program Guidelines because one of the Program's stated goals is to safeguard the heritage of the City by providing for the preservation of Historical Resources which represent significant elements of its history, and is inconsistent Secretary of the Interior's Standards discouraging the removal or relocation of historic buildings or landscape features, thus destroying their historic relationship within the setting. 6. Antonio Pinho was an important historic figure at a statewide level, since he served as the sixth Supreme President of IDES administration in 1906-1907, a statewide Portuguese-American fraternal organization in 1906-1907, and was locally significant in the development of the City, serving two terms on the Board of City Trustees. Committee member Whittlesey returned to the meeting. 2. Downtown Historic District. ARC 193-02. Review results of Historic Street.Light Demonstration and recommend lighting globe and bulb types. City of San Luis Obispo, Applicant. Jeff Hook presented the staff report and displayed working samples of the two types of globes and light bulbs being considered for Downtown. He discussed the results of the public survey done over.six weeks and explained that public preference was about evenly split between High Pressure Sodium and Metal Halide lamps, and between the POND (partially clear) and the Opaque (white) globes. After discussion, and on a motion by Committee member McMasters, seconded by Committee member Crotser, the Committee voted 7-0 to determine that the round POND globe, dark green textured pole, and 70-watt Metal Halide bulb are compatible with the Downtown Historic District and with the City's Historic Preservation Program Guidelines, and referred the project to the Architectural Review Commission with a recommendation to approve the historic pedestrian street lighting with the features noted. Committee members reiterated that 3�A6 s�3a Attachment 6 CHC Meeting Update, February 24, 2003 . Page 4 the round globe, and not acom shape, was preferred because it most closely resembled the City's original gas street lamps. COMMENT AND DISCUSSION: 2. Recognize and thank Committee Member Steve McMasters for seven years of service to the community on the Cultural Heritage Committee. Committee members thanked Steve McMasters for his service to the CHC and the community, and Steve shared his thoughts about changes to the CHC membership and role during his tenure. 3. Nomination of the CHC for the 2003 Governor's Historic Preservation Award. This award is given each year by.the Governor to promote broad public awareness and support for historic preservation. This item was briefly discussed, then continued to the March 24, 2003 meeting. 5. Staff A. Agenda Forecast Staff provided a brief agenda forecast, noting that a handicapped ramp addition for the Zion Lutheran Church was tentatively scheduled for the March meeting. The Committee adjoumed at 8 p.m. to the regular CHC meeting on Monday, February 24, 2003, at 5:30 p.m. in the Council Hearing Room (Room 9), 990 Palm Street, San Luis Obispo. ala► 5-33 Attachment 6 Attachment 7 COST COMPARISONS The overall cost of the pole and luminaire is the same for any combination of globe and ballast. However there are cost differences between a MH and a HPS installation due to lamp replacement costs and energy costs. There are also energy.cost differences due to optical performance between the pond and opaque globes. MH versus HPS Costs: • Lamp Replacement Cost: The average price for a HPS bulb is $20 compared to $32 for a MH. The life of a HPS bulb is approx 5.5 years (24,000 hrs) versus 3.4 years (15,000). Applying a$10/lamp labor costs for each replacement,the yearly lamp cost is approximately: HPS =($20+$10)/5.5 yrs =$5.45/yr MH =.($32+$10)/3.4 yrs =$12.35/yr • Energy Costs (efficiency): Of these two lamps, MH has a more balanced spectrum with strong peaks in the blue/green/yellow region of the spectrum, while HPS emits more light energy in the yellow/orange/red region of the spectrum. HPS lasts longer and have traditionally been considered more efficient when measured in "lumens per watt." However, research conducted over the last 10 years shows that the blue/green rich light of metal halides provides better "seeability" under low light levels of parking and street lighting. As light levels decrease, the effectiveness of orange/yellow HPS deceases and the effectiveness of blue/green MH increases. At night, the human eye can see more of the lumens produced from a MH light. Thus when comparing "effective lumens per watt," MH is considered more efficient. According to the results of the research conducted by Lewis,' in street lighting applications, MH was found 4-8 times more effective than HPS. He suggests using the average factor of 6X. Applying this factor, it would take a20OW UPS bulb to be nearly equivalent to a 70W MH bulb. Even applying the lowest factor of 4x, it would take a 150W BPS bulb as shown below in the example Example: 70W MH w/a mean lumen output of 3400 lumens (5200 initial)would require a HPS mean lumen output of 4 x 3400=13,600 lumens. This is close to a 150W HPS w/ a mean lumen output of 13,800 lumens (16000 Initial). Yearly energy costs (per PGE rates)for each system are estimated as follows: MH 70W = $2.305/mo x 12 mos. =$27.66/yr HPS 150W =$4.434/mo x 12 mos. =$53.66/yr (4X factor) HPS 20OW =$5.925/mo x 12 mos. =$71.10/yr (6X factor) • Total yearly costs for each system: MH 70W =$27.66/yr+ $12.35/yr= $40.01/yr HPS 150W =$53.66/yr+ $ 5.45/yr= $59.11/yr HPS 20OW = $71.10/yr+ $ 5.45/yr= $76.55/yr Lewin,Ian 1996.On the road again.LD+A 26(no.5):66-73. IESNA Lewin,Ian. 1999.Better Roads.www.beterroads.com/articles/broct99b.htm S � O � Attachment 6 Opaque versus Pond globe costs: The manufacturer states that there is a 40-50% light output loss when using the opaque globe instead of the Pond globe. Staff confirmed this through simple light meter readings while swapping the two different globe types. The results suggested a loss of about 46%. Taking this into account, a 70W MH would need to be increased to a 100W MH to account for the loss. The yearly added energy costs of using the opaque instead of the Pond globe would be around $9.37 per year. MH 100W =$3.086/mo x 12 mos. =$37.03/yr MH 70W = $2.305/mo x 12 mos. =$27.66/yr Added cost: $ 9.37/yr Additionally, it is staff's opinion that the white globe would be prone to showing more dirt and grime thus requiring more frequent cleanings. This would be some undetermined additional yearly labor cost added to the above figure if using the opaque globe alai Should vision influence roadway lighting design? Page 1 of 6 Attachment 6 Attachment 8_, Better oa s For the Government/Contractor Project Team October 1999 Back to Article Index Should vision influence roadway lighting design? by Ian Lewin Nighttime visibility is a critical issue to users of our highways and to those involved in street lighting design. Roadway accidents occur at a much greater rate during night hours than during the day. While there are many reasons for this, the major cause is believed to be reduced visibility due to low light levels. Economics and technical obstacles prevent lighting professionals from designing nighttime lighting equal to natural daytime lighting or even equal to the lighting in interior spaces. As a result, they must create the best nighttime visibility possible within the limits of practical design. One important step in this process is to identify the factors that affect visibility. Based on results of previous studies, The Illuminating Engineering Society of North America developed a proposed calculation procedure for lighting design based on visibility. The IESNA visibility calculation procedure does not,however,take into account the color output of the light sources, although they acknowledge its importance in their report. Recent research shows that the color output of the light sources used for roadway lighting has a significant effect on how well we see at night. Moreover, vision scientists have known for most of the twentieth century that the eye's response to color depends upon the amount of light available. Nevertheless, this important fact is often ignored when we measure the lumen output of light source. A lumen or not Lumens are the standard measure of light output. Lamp manufacturers and lighting professionals generally assume that all lumens are equal in terms of the visibility they create. This assumption can be proven incorrect. Standard measures of defining and measuring lumens provide a rated lumen output for a given lamp without considering that the eye sensitivity to the lumen output from a given light source varies, depending on the visibility conditions. http://www.betterroads.com/articles/broct99b.htrn 9/11/2002 Should vision influence roadway lighting design? =• Page 2 of 6 Attachment 6 A true assessment of the lumen output of a lamp should be based on the eye's response to the visibility conditions. Since any given lamp type is used under many viewing conditions,numerous lumen output values can be calculated for that lamp depending upon which condition is present. When the light level is very low, the viewing conditions are no longer photopic(high light levels). Instead, they are referred to as scotopic. Typical scotopic conditions are starlight levels at night. In between photopic and scotopic, mesopic conditions refer to twilight and typical street lighting levels. Under scotopic conditions, the eye's visual response changes dramatically. The eye's sensitivity to yellow and red light is greatly reduced, while the response to blue light is greatly increased. Clearly, if lamp lumen output under scotopic viewing conditions has been determined using photopic measurements, the lumen output value does not accurately measure the true amount of light produced by the lamp. In reality, the eye response does not shift suddenly from photopic to scotopic conditions. A gradual change occurs as light levels are reduced. This twilight zone is the mesopic condition in which the eye's response lies somewhere between photopic and scotopic. The change in the eye's spectral response is due to the presence of two types of light receivers in the retina of the eye. One receiver is called rods and the other, cones. Cones are active at high light levels and are located mainly in the central part of the human field of view. When we look directly at an object, we are using our cone receivers. The cones respond to photopic light. The rods are responsible for human vision at low.light levels and are located in the peripheral field of view, away from our direct line of sight. As the light level reduces, cones become less active, rods become more active. The rods are sensitive to scotopic light. Under nighttime driving conditions, both rods and cones are active. Objects viewed directly by the eye are seen by the cones. Peripheral objects gaze seen primarily by rods. Peripheral objects may be a car approaching down a side road or a child running towards the roadway. Rod vision is obviously very important in night driving. Color and lumens As an illustration, the blue output of an incandescent lamp is low. The eye sensitivity to blue light under photopic conditions is also low. The blue output of this lamp therefore produces few lumens under photopic conditions. The red power of the lamp is very high, In� 3)95 http://www.betteroads.com/articiestbroct99b.htm 9/1 V, Should vision influence roadway lighting design! rage s or o Attachment E but the response of the eye to red under photopic the red output produces only moderate lumens. On the other hand,the yellow output of the incandescent lamp is moderate, but the eye's sensitivity to yellow light under photopic conditions is very high. As a result,the yellow output of the lamp produces much of its lumens. This is why an incandescent lamp produces a slightly yellowish light, even though its main output is red. With this understanding, the high lumen output of high-pressure sodium lamps can be readily explained. Sodium produces light that is primarily yellow. The eye sensitivity to yellow under photopic conditions is very high. As a result,high-pressure sodium lamps have high lumen ratings as perceived by the eye. On the other hand, under scotopic conditions, the effective lumens are greatly reduced because sodium produces very little blue and green light. These effects with low-pressure sodium lamps are even more dramatic. Almost all energy output with this lighting source is in the yellow region, giving very high photopic lumen output. At.low light levels, LPS has drastically reduced effectiveness. The lumen output of a lamp is modified when the shifting color sensitivity of the eye at low light levels is taken into consideration. The term effective lumens can be used for this modified lumen output. The effective lumens will be different from the measured photopic lumens. Metal halide lamps A typical metal halide lamp has strong light output in the blue, green, and yellow regions. The result is a high lumen output for this light source at all light levels. The blue light output of metal halide is in the high sensitivity region of the eye for low light levels. This means that the effective lumens actually increase for a metal halide lamp as the light level reduces the.eye shifts to a blue/green peak sensitivity. As the light level diminishes from photopic,through meso-pic, to scotopic conditions,the effective lumens of yellow light sources are reduced and the effective lumens of blue/green sources increase. But has this effect actually been demonstrated in real life situations? Several research projects conducted with human subjects support these conclusions. For example, Dr. Alan Lewis, Dean of the Michigan School of Optometry, and his colleagues conducted vision experiments using various light sources, including mercury, metal halide, high-and low-pressure sodium and incandescent. The tests were carried out over a range of lighting levels from photopic 31ab http://www.betterroads.com/articiestbroct99b.htm 9/11R/20 Should vision influence roadway lighting design? Page 4 of 6 Attachment 6 down through mesopic to scotopic. In the first series of tests, the ability of the eye to see the difference, or the contrast, in brightness between an object and its background was measured under different conditions. In one experiment, the subjects were shown a grating where the amount of contrast between the lines in the grating was varied. Five different light sources were used to light the grating. Under the metal halide source, the ability to detect fine contrasts is significantly better than under sodium sources. Other experiments measured the reaction time of the test subjects, meaning how fast they were able to distinguish contrasts. The tests were conducted under different light sources, and the light levels were varied. In one test, the subjects were required to identify whether a grid of lines was horizontal,or vertical under a wide range of light levels. In another study, subjects were shown a photographic transparency of a woman standing at the side of a roadway near trees and a fence. In some cases,the woman in the photograph was facing the roadway while in other cases she was facing away from the roadway. Test participants were required to identify which way she was facing; and the time it took them to make this identification was recorded. At low street lighting levels,there is considerable difference in results for the various light sources. The reaction times for high-and low-pressure sodium are roughly 50% longer than for metal halide. These results clearly demonstrate that the color output of a light source has an important influence on visibility and that the effects are real and significant. Effectiveness of lamps In other tests, Dr. Lewis has compared the response time of test subjects under different light sources. Dr. Lewis has evaluated sources at both high and low street levels for the same reaction time and task. The testing was conducted first at a fairly high street lighting level such as might be found on major roadways. Since Dr. Lewis has found metal halide to be the most effective source,he used it as the basis of comparison. His results indicate that a high-pressure sodium lighting system needs to produce a light level 3.9 times higher than metal halide, to be equivalent to a metal halide system, under the test conditions evaluated. For low-pressure sodium,4.8 times more light is required to be equivalent to the metal halide level. Dr. Lewis conducted similar research at low light levels found in fairly dark areas of a roadway. This may be the most significant http://www.betterroads.com/articlesibroct99b.htm 9/11/200-2 Should vision influence roadway lighting design! rage --i or b Attachment E data of all, because accidents are more likely to occur in dark areas. Such dark areas are;also common off the roadway in areas where a driver needs to detect a hazard approaching from the side using peripheral vision. These results show that 7.8 times as much high-pressure sodium luminance must be provided to be equivalent to metal halide. For low-pressure sodium, 14.6 times the light level must be produced to be equivalent to metal halide light. A high-pressure sodium lighting system will require approximately 6 times the luminance level of an equivalent metal halide system. Consequently, a roadway lighting system powered by 150-watt metal halide lamps will be equivalent to a high-pressure sodium system using lamps of six times the lumen output. The initial lumen output of a 150-watt metal halide source is 15,000 lumens, and therefore the high-pressure sodium lamp for equivalent visibility under the described conditions must have an output of 90,000 lumens. This would require high-pressure sodium lamps of about 700 watts to match the 150-watt metal halide lamp. Even assuming a faster lumen depreciation for metal halide versus high-pressure sodium,this is a huge difference. The comparison between metal halide and low-pressure sodium lighting showed that between roughly 8 and 14 times as much light is required from the LPS system to have the same effectiveness as metal halide under these conditions. The 6 times greater average luminance level of halide versus high- pressure sodium occurs where it is strongly needed,that is, in side or peripheral viewing and dark areas, where otherwise hidden hazards may be present. The increased visual effectiveness of white light with a high blue/green content under these nighttime conditions is dramatic. The powerful, independent data,which has been corroborated by several researchers, is worthy of serious consideration by roadway lighting design professionals.

My biggest concern about this project is that it will increase the amount of light pollution in San Luis Obispo. Poorly designed lights can increase glare (actually reducing effective visibility) and increase light directed towards the night sky, causing the unsightly light pollution common in many large cities. To quote "http://www.darksky.ora/fixtures/posttot)D.html":. (Post Top "Period" lights) should be used with the minimum amount of lumens possible,and be thought of as decoration. Hence they look as good. at night as in the day. With too much lumens,no one can see the fixture at night anyway. The problem is trying to do two things with one fixture: historical look and street lighting. The needs are different and should be met by different schemes. If they must be used,then the following examples are much better choices than many others that exist,for they at least do some control of the light output. If design and fixture selection are not carefully done,then glare, light trespass, and energy waste may well be maximized, rather than enhancing ambiance and visibility. It is essential to understand that there are products available to address the issues of glare, light trespass, uplight, light pollution, energy waste and still provide historic appearance. As so often happens in historical areas or even in older parts of cities and towns, old fixtures are retrofitted with much higher light output lamps(ruining the ambiance) or new fixtures are selected with no consideration for optical performance. I strongly encourage you to look at the following websites as they contain a wealth of information on this important topic and will help guide you in the selection of lighting that minimizes the glare and pollution to the night sky: http:llwwW.darksky.org/fixtures/posttopp.html http://www.niagaramohawk.com/lighting/non html/naomi.pdf http://Www.netacc.net/—ooulsenjacorns.htmi httl)://www.darksky.org/ http://WWw.monmouth.com/—ksears/litepoll.htm Please don't hesitate to contact me if you would like to discuss this or would like further information. Thank you for your time. - Christopher Ellwood Bridget Fraser Associate Engineer City of San Luis Obispo Public Works Department 805-781-7192 fax 805-781-7198 Response from Bridget Fraser, 1/28/03 3131 !�;-43 Attachment 6 Mr. Ellwood, Thanks for your comments and website references. You'll be happy to know that we are familiar with the Dark Skies organization and have been to 4 of the 5 web sites you listed. The issues of light pollution, efficiency, etc will be taken in to consideration when making the final selection of luminaire to use downtown. With the push for less light pollution manufactures are coming up with many post top designs that are rated as semi-cutoff or better. We were fortunate in being able to come up with a historic design that was still rated as semi-cutoff. In the current demo installation downtown,the globe near Frog and Peach is semi-clear and the other across the street is opaque.The semi-clear fixture is rated as a true semi-cutoff fixture. The other fixture in front of Posies, although equipped with the same optical system is not technically considered semi-cutoff. This is due to the light being diffused outward by the opaque globe and not passing through the globe to the ground. (However with the large "tophat" much of the light is kept from going upward.)The advisory bodies and Council will need to take this into consideration when finally choosing a luminaire. There will be a balance between historic styling, efficiency and cutoff features among many other things. I welcome you to come in and talk with me anytime or come down to Farmers Market on Thursday night of this week as we will have a booth set up to take public opinion. Again, I thank you for taking the time to express your concerns. >>> Brian Starr 02/13/03 02:51 PM >>> I am writing to express my support of the Metal Halide light fixtures las opposed to the High Pressure Sodium) recently installed on Higuera Street. The Metal Halide has a much better color rendition. High Pressure Sodium is what gives Santa Maria such a drab appearance at night. I also prefer the partially obscure globe as opposed to the opaque one. With regard to the globe, I believe an"acom" shape is more in keeping with an older downtown than a round globe more typical of the 60'2 and 70's. Thank you for your careful research. The selection of proper lighting will have a huge impact on the night time appearance of downtown and can attract people or drive them away. Brian Starr Bridget Pierre Rademaker contacted me and said he fees VERY strongly that we picked the wrong globe. He feels an acom shape (available from the same manufacturer)is much more historically accurate, and that the round shape is refelective of the 60s. Pierre is a very knowledgable dign person with much experience with this kind of thing,.

I want to thank Ms. Bridget Fraser from the city engineering department and your commission for bringing new pedestrian lighting to our downtown. I understand your commission will be making a decision about the type of globe and the lamp or bulb that is used in the new pedestrian lighting. I would encourage you to consider health, safety and welfare issues as well as the esthetics inmaking your choice. With regards to health, safety and welfare issues,-the scientific research is quite clear on this subject. People can see better at night under the lighting of metal halide bulbs. The reason is that metal halide is a whiter light and the physiology of the eye is such that our visual acuity is significantly improved at the white/blue end of the color spectrum. High pressure sodium emits an orange light. Well researched studies indicate people cannot see as clearly under this light at night because it doesn't activate the rods in the eye which we use for night or low light vision. This means that metal halide lamps are safer lights to drive by. Motorists driving down Higuera at night will be able to clearly see pedestrians on the side walk or pedestrians coming out between cars to cross the street. Elderly motorists generally have decreasing visual acuity so they will appreciate being able to drive more safely where the light source is the whiter light given off by the metal halide bulbs. Another major safety concern is how bright must the street be for drivers to see safely. The Electrical Engineering Society of North America (EISNA) publishes illumination guidelines that many cities and agencies refer to when looking for lighting standards. The EISNA is developing new 333 1�-, W AttachmPnt 6 guidelines on rating the perceived brightness or lumen output of different lamp types such as high pressure sodium vs. metal halide. The results of considerable scientific research indicates that metal halide is best for night vision in comparison to high pressure sodium and we need less of the metal halide light to see more clearly. Because the eye utilizes white light more efficiently we don't need as much. Recently, new multipliers are listed in EISNA literature that give metal halide a bonus factor over high pressure sodium when determining perceived brightness at mid-street. An additional benefit of lowering the light out put of the metal halide lamps, is that they are perceived as less bright and more esthetically appealing as well a easier to see by. Our downtown lighting should also take into consideration the needs of the store owners and vendors selling their goods on Thursday nights. Store owners and vendors will appreciate the improved color rendering of metal halide lighting over the orange high pressure sodium. The colors of-store fronts and merchandise are more accurately depicted with metal halide. The green trees that line the street look green under metal halide light. Trees, shops, merchandise and people do not look good under high pressure sodium light. The reason for this is that high pressure sodium is like having one orange crayon and a few muddy shades to color with. To color a green tree, store front, merchandise or people and their skin tones, you're basically stuck with orange. The scientific fact is that high pressure sodium has the worst color rendering capability of all light sources. When you take into consideration the safety and esthetic factors in making a decision about whether to use metal halide or high pressure sodium, it is my professional opinion that the metal halide lamps are the best source of light for the task of illuminating our new fixtures. At first glance, high pressure sodium may look appealing to some people because of its orange look. As you research further, you realize that it is not as safe to drive under near pedestrians and is the worst source of light for color rendering. Metal halide light may appear to white and bright to some people. Using lower wattage bulbs that are frosted can mitigate this. By lowering the wattage and brightness you still achieve the number of foot candles on the street because of the bonus factor given to metal halide when rating its light output. I hope this information will help you make a decision about a choice of lighting based on the latest scientific research and esthetic (3)31 S'-qLP Attachment 6 considerations.

Design Guidelines 61-Miseellaeuous Design Details C. Lighting. Exterior lighting should be designed to be compatible with the architectural and landscape design of the project,and not create a nuisance for adjacent and nearby properties. 1. All outdoor lighting shall be directed downward and not spill onto adjacent properties. 2. An appropriate hierarchy of lighting fixtures/structures and intensity should be considered when designing the lighting for the various elements of a project(i.e.,building and site entrances,walkways,parking areas,or'other areas of the site). 4. To achieve the desired lighting level for parking and pedestrian areas,it is preferred to have more,smaller scale lights instead of fewer,overly tall and large lights. Parking lot lights shall be as low in height as possible,and shall not exceed a height of 20 feet from the approved finished grade to the top of the fixture. Fixtures should be down-type lights with shields,preferably with metal halide lamps. Illumination levels at the finished grade below the each light fixture shall not exceed 10 footcandles under the fixture,and three footcandles at the dimmest point. S. The design of outdoor light fixtures should be in keeping with.the architectural style of adjacent structures. Outdoor wall-mounted fixtures should not exceed a height of 14 feet or the height of the building,whichever is less. Photometrics must accompany a request for taller lighting fixtures,and will require specific ARC approval. 6. The use of exterior lighting to accent building architecture is encouraged. All lighting fixtures should be properly shielded to eliminate light and glare from impacting adjacent and other properties,and passing vehicles or pedestrians. When neon tubing is used to illuminate portions of a building it should be concealed from view by parapets,cornices or ledges. Small portions of exposed neon tubing may be used to add special emphasis to an architectural feature,but this must be well thought out and integrated into the overall design 7. No lighting on private property shall produce an illumination level greater than one footcandle on any property within a residential zoning district except on the site of the light source. 8. No permanently installed lighting shall blink,flash,or be of unusually high intensity or Z- brightness. 9. Exterior lighting should enhance building design and landscaping,as well as provide for safety and security,but should not create glare for residents or neighbors. Cut sheets or details of lighting fixtures shall be submitted with plans to confirm that lighting will be cast downward,rather than spreading glare onto adjacent properties. 0 d 10. Lighting fixtures should be durable,and of a design that complements building design and �v landscaping. r 3J� Chapter 6-Site Planning dz Other Design Details November 2002 C01 Attachment 7 ----------._ _--- ...._._.......... a _ t � v _ 'COO Co W LU Co LU 2 � v _ Q W I � '-' -H U . ....... - - - - IT v f i i GVOld 9 Attachment 8 RESOLUTION NU.
