Home My WebLink AboutAGENDA REPORT 1993 1103 CC REG ITEM 11HTO: FROM: DATE: ITEM 199-5 AGENDA REPORT CITY OF MOORPARK The Honorable City Council Jaime R. Agullera, Director of Community Development Prepared by Kathleen Mallory, Associate Planner K /'n October 29, 1993 (City Council meeting of November 3, 1993) SUBJECT: CONSIDER A REPORT REGARDING THE INSTALLATION OF THE DOWNTOWN STREET LIGHTS BACKGROUND On August 18, 1993, the City Council considered a report by staff regarding preliminary cost estimates for an electrical engineer to prepare a photometric plan for High Street. During this meeting, the Council reached consensus regarding the following: a photometric plan should be prepared for both the north and south sides of High Street (if possible, obtain the photometric plan from the light fixture supplier at no cost or a lesser cost than the cost outlined within the bids received; the selected light pole should be black marbelite - with a mounting height of 14 feet; that the existing light poles, in their current positions, should not be included in the photometric plan; and that the funding of the downtown street lights be referred to the Moorpark Redevelopment Agency. During this Council meeting, the Council determined that the Public Works, Facilities and Solid Waste Committee (Councilmembers Montgomery and Wozniak) should review the issue of street lighting and develop recommendations regarding the following: is the light pole and selected lighting fixture appropriate; what illumination level would be appropriate for High Street; and what light source should be utilized. The Committee also developed recommendations regarding the light wattage and street width. The purpose of this staff report is to present to the Council the Committee's recommendations, to receive Council concurrence that the lighting system on High Street will be an Edison owned system and that Edison will be responsible for electrical planning, and possibly construction and installation. *AP- 10.M93(12:02pm)A:1CC113. RPT The Honorable City Council October 29, 1993 Page 2 DISCUSSION On August 25, 1993, the Committee discussed the scope of services required to develop a photometric plan for the downtown street lights. On September 20, 1993, the Committee heard a presentation by the lighting engineer regarding acceptable wattage levels. During the August 25, 1993 meeting, the Committee drafted recommendations regarding the following: Lighting Pole and Light Fixture The Committee selected the single luminaire black Washingtonian street light pole. The pole is constructed at a standard height of 14 feet. For the Council's information, the pole is 14 feet in height; once the luminaire is mounted, the total height of the pole and luminarie will be 15 feet 8 inches. The Committee was informed by staff that the Acorn lighting fixture (King luminaire) had been designed specifically for the Washingtonian light pole and that, under the LS -1 utility rate, the King luminaire was the most efficient luminaire for the selected pole. The Washingtonian street light is the on Edison approved decorative street light. There are other decorative street lights; however, these poles are not Edison approved and subsequently, the rate structure for energy costs are significantly higher. Committee Recommendations - 1 -3 The Committee recommended: (1) that the Washingtonian light pole, under the LS -1 utility rate schedule (ie., Edison owned) and (2) King Acorn lighting fixture be installed within the downtown; and that (3) the manufacturer apply the anti - graffiti spray to all light poles ordered for High Street. Light Source, LS-1 Utility Rates, See Attachment Number 1 Given that almost all of the street lights within the City are High Pressure Sodium, the Committee recommended that High Pressure Sodium be utilized for the downtown street lights; however, a variety of light sources are available for the Acorn light fixture. Light sources available for the selected pole and lighting fixture include: Incandescent Lamps, Mercury Vapor, High and Low Pressure Sodium. Metal Halide has not been listed as a light source option on the LS -1 utility rate schedule due to cost and energy inefficiency. Edison has indicated that Metal Halide may be available for the proposed light fixture; however, the cost would be roughly 30% higher than the LS -1 utility rate for High Pressure Sodium. KMP- 10- 08-93(12:02pm)AACC11.3. RPT The Honorable City Council October 29, 1993 Page 3 Committee Recommendation - 4 The Committee recommended: that the lighting plan be based upon High Pressure Sodium for the downtown street lights, seen within Attachment Number 2 and 3. Light Sources, as R relates to Astronomy The selected light source is important because different light sources give off different wave lengths of light. These wave lengths of light give off bands of color which are used to identify components of celestial objects. Concern has emerged regarding the use of Low Pressure Sodium vs. High Pressure Sodium in the application of astronomy. If astronomers are doing spectroscopy (which is the study of individual components of color given off by celestial objects) then astronomers would be concerned with the selected light source. In this circumstance, astronomers would support the use of Low Pressure Sodium because this type of light source produces only two wave lengths of light or bands of color. If astronomers are just observing celestial objects, then astronomers would not be especially concerned with the selected light source and subsequently the bands of light produced by the light source. Moorpark College is not concerned with identification of new planets or doing scientific research (spectroscopy) but is instead interested in observation. Therefore, the use of High Pressure Sodium should not be of concern to the College provided that appropriate shields and Caps are installed as part of the street lighting system. Committee Recommendation - 5 The Committee agreed that the use of High Pressure Sodium for the lighting of High Street will not result in impacts to spectroscopy or general observation. Photometric Wattage At the Committee's August 25, 1993 meeting, the Committee directed staff to obtain two (2) photometric plans based upon different wattage levels, to be determined by the lighting consultant with sensitivity to light pollution. The intent in having the lighting consultant prepare two photometric plans at different wattage levels would enable the Committee and staff to compare lighting impacts associated with varying wattage levels. WP- 10- M93(12:02pm)A:1CC113.RPT The Honorable City Council October 29, 1993 Page 4 The consultant recommended preparing a photometric plan based upon 100 and 70 watts. Photometric plans based upon the aforementioned wattage levels were presented to the Committee on September 20, 1993. The Committee's recommendations are as follows: Committee Recommendations - 6-8 The Committee determined that: (6) the lighting system should be based upon a single post top light pole, 100 watt Acorn luminaire (see Attachment Number 4), with the "house - side" shield removed at time of installation; (7) the underground electrical system should be designed based upon a double arm light pole and a 150 watt Acorn luminaire; and (8) that the lighting system be designed in order to provide electrical wiring for decorative lighting, such as Christmas lights, etc. (the wattage level for decorative lighting should be recommended by Edison). Removal of the "house- side" shield will result in additional lighting of the sidewalks. The shield is normally left inside of the light fixture, except when additional lighting in a specific location is needed. Furthermore, by installing a below ground system which provides the capability to supply more light than is presently needed, upgrade costs are reduced if, in the future, the lighting system needs to be upgraded. Street Width The lighting engineer designed the street light system at a street width of 50 feet; the Committee recommended that the street light system be designed at 46 feet. The existing street varies between 46 and 62 feet 10 inches, at its widest point. The poles will be placed 3 feet behind the curb - providing illumination in the most important locations, the sidewalk and parking lane. While the street may be wider than 50 feet in certain locations, the important locations (the sidewalk, where one exists, and the parking lane) will still be illuminated. In those locations where the street width is greater than 55 feet, illumination levels will be reduced by approximately 1 /10th of a footcandle; the reduced footcandle level will be nominal, and according to the lighting engineer, will not significantly reduce desired footcandle levels. Electrical Planning. Construction, and Installation In order to install the lights and other electrical lines, an electrical plan will need to be prepared for High Street, with construction and installation to follow. Given that all of the street lights within the City are Edison owned, it is staff's opinion that the downtown street lights should also be Edison owned. KMP- 10- 08-93(12:02pm) AACC113. RPT The Honorable City Council October 29, 1993 Page 5 Edison Owned System Since the September 20, 1993 Committee meeting, staff was informed that for an Edison owned system, the City has no option but to have Edison design the electrical system for each street light. The electrical plan is done by SCE, at no charge to the City and no charge is absorbed into the LS-1 utility rate. With an Edison owned system, the City would have the option to either hire a company to perform the necessary construction (open /close trench and provide any required conduits) consistent with the Edison electrical plan, or pay Edison a flat rate per foot for the construction/installation. An estimate of this rate will be provided to the Council at a later date once the electrical plans are drawn. This cost is not included within the LS-1 utility rate. The Council should be aware that in 99% of the cities within Califomia, the street lights are owned by public utilities and not cities. Non - Edison Owned System ff the City wishes to own the lights and undergrounded electrical system, the City would be responsible for hiring an electrical engineer to design the system consistent with Edison requirements. Further, the City would also be responsible for hiring a construction company to install the street lights. RECOMMENDATIONS Concur with recommendations 1-8 made by the Public Works, Facilities and Solid Waste Committee. 2. Staff recommends that the Council support the idea of an Edison owned system. If the Council concurs, the following recommended actions should be authorized: a. Authorize staff to begin working with Edison to design the electrical system and to ask Edison to complete the electrical plan by January 1994. b. Direct staff to procure from Edison the fiat rate fee per foot for construction and installation. Staff shall present this information to the Council /Redevelopment Agency for their decision as to whether the City /Agency should contract with Edison or pursue a competitive bid process.

CE36.12 Yirn PrrtidPnt Resolution 4+hctc,t�m INFORMATION SHEET NUMBER 12 (Edition No. 2, December 1989): 10I INTERNATIONAL DARK -SKY ASSOCIATION 3545 N. Stewart Tuc-son AZ 85-16 U.S-A. Recommendations about Effective Outdoor Lighting In order to carry out astronomical and other space related research, a dark nighttime sky is essential. Contributions of light from the earth, both direct emissions and reflected light, tend to brighten the night sky background. The same brightening ruins the view of the heavens for amateur astronomers and the general public. Many people have never seen the Milky Way, much less other interesting objects. The type of light emission is also important because some types may be filtered at the telescope more efficiently than others, low pressure sodium being the most preferred source. The following gives suggested uses, by light source type: Low Pressure Sodium (LPS) Roadways, Walkways, and Parking Areas Outdoor areas needing security lighting Residential security lighting Any area where color rendering is not critical High Pressure Sodium (HPS) Sport parks, and Tennis Courts Security areas where color rendering is critical Metal Halide (MH) Display lighting where color rendering is critical Some sports lighting, where color rendering is critical Mercury Vapor (MV, or HG) Not an energy efficient source, not recommended. Use MH instead. Older installations, where shieldin j5 gjQ-�J, can remain in use, of course. Incandescent, including Quartz Not energy efficient, but OK for low wattage applications. Low wattage lamps for porch lights, and other low wattage usages. Should be well shielded. In general: All outdoor fixtures should be fully shielded and installed in such a way that no light is emitted above a horizontal plane running through the lowest part of the fixture. Thus glare, light trespass, and light pollution will be minimized, and energy savings will be maximized. Low pressure sodium should be used wherever possible (where color rendering is not critical). Use time controls or motion sensors to turn lamps off when not needed. (Relative to use as security li ghting: LI'S has the ability to restnke immediately after a momentary power failure, while HPS must cool before restnking.) of ATTACHMENT 3 Incandescent Lamps (which looks like Natural Light, same spectrum as the sun) This type of light source is the most common lamp used in homes, indoors and outdoors. It is the most energy inefficient of the common lamp types. Incandescent lights are one eighth ( %) as energy efficient as Metal Halide, one half ('/2) as energy efficient as Mercury Vapor, one fifth (1/5) as energy efficient as High Pressure Sodium, and one tenth (1/10) as energy efficient as Low Pressure Sodium (source information for the International Dark Sky Association). Mercury Vapor (which looks like Purple- Greenish Light) This type of light source is the most commonly used for outdoor applications, such as "security" lighting. This type of light source is not energy efficient. This type of light source requires a "ballast", which is a spark increaser (like a spark plug) which is an expensive part of the light fixture. High Pressure Sodium (which looks like Yellow Light) This type of light source is primarily used in the outdoors, for street lighting and parking lot lighting. This type of lighting is the most energy efficient with good color performance. It is more energy efficient than metal halide and is a good choice when white light (Metal Halide) is not needed, but where vv yellow light is not desired. Based upon the LS -1 utility rate schedule, this type of light source is the most cost efficient. The maintenance cost for High Pressure Sodium will be lower than for Low Pressure Sodium. This is due to the fact that High Pressure Sodium is the most commonly used light source, therefore, parts are more readily available and the cost is lower for the replacement of these parts. Low Pressure Sodium (which is Vern Yellow Light) This type of light source is the most energy efficient, but is not the most cost efficient. Additionally, the very yellow light results in poor aesthetic value. This type of light source produces a very yellow light and glare. Prolonged exposure to Low Pressure Sodium lights tends to cause eye irritation, headaches and color distortion. The Police Department does not support the use of this light source because it does not render colors accurately and may wash out signal colors. *AP- 10.08-93(12:02pm)A:=11 -3. RPT Metal Halide (which Is White Ught) These lamps are used for both outdoor and indoor applications. They are currently the most energy efficient of the "white light" source and approximately twice as energy efficient as mercury lamps. Edison has not established a utility rate for this type of light source and, tentatively, would be able to develop a utility rate for Metal Halide. Preliminary cost estimates indicate that the LS-1 utility rate for Metal Halide would be roughly 30% higher than the LS-1 utility rate for High Pressure Sodium. *AP- 10- M93(12:02pm)A: \CC11 -3.RPT 2 South ea-f-ut -444 y & ? wow 28052 CAMINO CAPISTRANO #209 LAGUNA NIGUEL.
