Passed this day of 008. r - Presidinu Officer ATTEST: Clerk of Council 1 Office of the City Manager 52QQ Emerald Parkway • Dublin, OH 43017-1Q06 CITY OF DUBI.IN_ Phone: 614-41Q-44QQ • Fax: 614-410-4490 M e m o TO: Members of Dublin City Council FRONI: Jane S. Brautigam, City Manager DATE: February 14, 2QQ8 INITIATED BY: Steve Langworthy, Director, Land Use & Long Range Planning RE: Ordinance 08-08 {Amended) -Amending Chapter 153 of the Dublin Zoning Code to Establish Exterior Lighting Requirements. (Case No. 07-109ADM) Request The purpose of this Code modification is to add regulations to govern exterior lighting for development within the City of Dublin. The proposed Code modification outlines site lighting requirements, including fixtures, light trespass and pedestrian and landscape lighting, as well as administration procedures. Currently, certain provisions included in this Code have been applied through the Exterior Lig7~ting Guidelines. This proposal will strengthen the applicability and enforceability of these requirements by adopting them as a part of the Zoning Code. Reconmtendation of Plamwtg and Zo~wig Coriunission The Planning and Zoning Commission recommended approval of the Code modification on November 15, 2007. Issues discussed by the Commission included adequacy of site lighting, effects on neighboring properties, and "night sky" protection. The Dublin Police Department asked for consideration of potential safety concerns associated with a provision calling for reductions to parking lot lighting after occupancy. At the Police Department's suggestion, and to address the Commission's comments, Planning has provided additional language that gives the Chief of Police the oppo7-tunity to request a waiver from the lighting reduction requirements for a given site, based on business operations or safety statistics. City Council Comments This ordinance was introduced by City Council at the February 4, 2008 meeting and revisions were made in response to concerns regarding sign lighting restrictions, parking lot light reduction and compliance for existing sites. The revised ordinance deletes the previous restrictions on sign illumination and requires that only new developments with parking lots in excess of 250 spaces reduce lighting by 50 percent. This reduction can be accommodated through a combination of light level adjustments or through the extinguishing of fixtures. In addition, a property owner may maintain full lighting levels within 1 ~0 feet of the main entrance for security purposes. The revised ordinance also includes requirements for compliance of nonconforming lighting when the modifications exceed a specified percentage, 50 percent for expansion or 25 percent for fixture replacement. Additional Information At the February 4, 2008 City Council meeting, additional infornlation was requested regarding the International Dark Sky Association, as well as current examples of businesses that reduce Memo to Council re. Code Amendment to Establish Exterior Lighting Requirements. February 14, 2008 Page 2 of 2 lighting after hours. The International Dark Sky Association is a nonprofit organization that. focuses on the use of quality outdoor lighting in an effort to protect the night sky environment and reduce the adverse effects of light pollution. The organization «~as established in 1988 and provides resources regarding appropriate outdoor fixtures, and lighting regulation guidelines, as well as educational information about light pollution and its affect on the environment. Planning has found four examples of businesses that currently strive to minimize light trespass onto adjacent sites. These include the King Thompson office building at 7240 IVluirfield Drive, the Dublin Community Recreation Center, The Preserve office buildings at 5350 Frantz Road and Radiant Life Church at 7100 Post Road. These businesses utilize a variety of methods to reduce lighting levels, which include the use of designated fixtures that are shut off at a specified time, the use of lower wattage fixtures, decreased pole height, and the installation of light shields. In addition to the existing locations, the following developments were recently approved with reduced lighting requirements: Shamrock Crossing development including Leo Alfred Jewelers and Germain Service Center, Sunrise Senior Living and the commercial portion of the Tartan Ridge development. Description The proposed Code section is based on, and expands the existing Exterior Lighting Guidelines, providing requirements that are more specific. Lighting has been a continuing issue during the review of recent development proposals and how nearby uses affect or are affected by site lighting. During these discussions, it was clear that the Guidelines did not always adequately deal with the wide variety of situations being encountered, and the fact that they were not part of the Zoning Code called their enforceability into question. The inclusion of Exterior Lighting Requirements within the Zoning Code will help ensure that City-wide standards for site lighting are met and that light trespass is minimized. The new Code language is divided into four sections: • Purpose and Intent; • General Requirements; • Site Lighting Requirements; and • Administrative Procedures. The site lighting requirements identify the types of shielding and fixtures to ensure reasonable levels of lighting for security, but limit the levels of intensity to surrounding properties. In addition, the site lighting requirements provide for a reduction of parking lot lighting to 50 percent for certain new developments. The administration provisions outline submission requirements and processes for existing lighting and modifications to exterior lighting after approval. Recommendation Planning recommends Council approval of Ordinance 08-08 (Amended) at the February 19 Council meeting. 08-08 (<~mended) AN ORDINANCE AMENDING CHAPTER 153 OF THE DUBLIN ZONING CODE TO ESTABLISH EXTERIOR LIGHTING REQUIREMENTS.

Goals 1. Stop the adverse effects of light pollution, including; • Energy waste, and the air and water pollution caused by energy waste • Harm to human health • Harm to nocturnal wildlife and ecosystems • Reduced safety and security • Reduced visibility at night • Poor nighttime ambience; and 2. Raise a~;rareness about light pollution, its adverse effects, and its solutions; and 3. Educate about the values of quality outdoor lighting. To achieve these goals, IDA takes an award-winning unified approach that supports the individual efforts of our members and of others who advocate quality outdoor lighting. In fighting light pollution we work with communities, astronomers, ecologists, and lighting professionals. We are active on local, national, and international stages and have already accomplished much, but our work is not yet done. Fact Sheet IDA's goal: To preserve and protect the nighttime environment and our heritage of dark skies through quality outdoor lighting. IDA works collaboratively worldwide-with the public, industry, and government to halt the adverse environmental impact of light pollution on the nighttime environment Icy educating everyone about the value and effectiveness of quality nighttime lighting, conducting research, and engaging in outreach activities. IDA was founded in 1998 as a 501(c}3 non-profit educational organization. IDA activities include: Publishing the award-winning quarterly publication, l~jrghtscape Publishing an electronic newsletter International Dark-Sky Association Page 2 Developing and distributing practical guides and information sheets, brochures, leaflets, economic information, good lighting design examples, images, CDs, videos, and other resources and references Promoting and supporting viable and effective Sections and Affiliates in communities, regions, and countries Conducting and sponsoring annual general and specialty conferences around the globe Disseminating press releases and other media communications Conducting light pollution education and awareness programs Creating photo and video documentation of good and bad lighting Presenting Good Lighting Awards Participating in Speakers Bureau events and other media. lUlaintaining effective and efficient operations; 2008 SASIE Award Finalist for best innovative use of technology Sum~nai-y of the Issues: Quality nighttime lighting is the key to reducing light pollution. It means better visibility at night, freedom from glare, an improved and comfortable nighttime ambiance, and very significant energy savings. Everyone wins. Nlost existing astronomical observatories suffer from light pollution, radio interference, or the effects of space debris. Amateurs and professionals alike are adversely affected by these environmental obstacles. C~bsei•~~atories are increasingly being threatened by these problems. The profoundly human experience of the inspiring beauty of the night sky is at risk for all people, not just scientists, as light pollution destroys our view of the cosmos. ©vervie~~ ID 4 is still rapidly growing and now has over 10,000 members, from all 50 states in the USA and 70 other countries. About five percent of the membership are organizations, including astronomy departments, observatories, amateur astronomy clubs and organizations, lighting companies, and cities. More than 25 percent of those t~-•ho join or renew have done so at more than the standard $30 membership rate. There are currently 130 IDA lifetime members, 17 of them organizational members. International Dark-Sky Association Page 3 IDA has published newsletters since its founding in 1988 and developed more than 100 information sheets and practical guides. Lists of these are available on the IDA Web Site, «•«•«•.darksky.org. There are currently 8 slide sets of 20 slides each, t~~~ith captions. IDA has held an Annual Conference in Tucson each year since 1988. There have been numerous regional meetings as well, in many locales throughout the USA and in other countries; the frequency of these is increasing. IDA Sections also have regular meetings. The IDA newsletter gives details of upcoming IDA meetings, as well as other meetings of interest to members. The IDA Web site contains a lot of useful information, including copies of most of the IDA information sheets, the latest newsletters, many images, and other resources for those interested in the issues. The International Dark-Sky Association ~~~as incorporated in 1988 as atax-exempt, non- profit organization, exclusi~•~ely for educational and scientific purposes «~ithin the meaning of Section 501(c)(3) of the United States Internal Revenue Code of 1987 (IDA's Federal Identification Number is 74-2493011). IDA operates under formal bylaws, established at the time of incorporation and revised at the first annual meeting, February 1989, and again in September 1990, April 1999, and May 2000. SAMPLE LIGHTING ORDINANCE NASHVILLE, INDIANA ORDINANCE 2000-O1 AN ORDINANCE OF THE TOWN OF NASHVILLE RELATING TO LIGHTING TRESPASS WITHIN THE TO«'N OF NASHVILLE AND THE GENERAL REGULATION THEREOF WHEREAS, the Nashville Town Council is aware that businesses may desire to use various forms and types of lights to attract the attention of passer byers to said business and that residents may wish to install or maintain lights to provide a sense of security; and WHERE:~S, the Nashville Town Council is aware that Nashville has been recognized nationally as a unique place to shop and dine in that it contains over tluee hundred craft and specialty shops and that until 1999, the town has maintained a quaint appearance without billboard, neon, flood and other types of lighting that is found in other famous resort areas; and ~'VHEREAS, the Nashville Town Council has conducted an extensive review of the unique historic, rustic and quaint attributes of the Town of Nashville as well as its architectural styles and general building design and have concluded that the improper use of exterior lighting by businesses or home owners detracts from these attributes and the natural environment of Brown County; and WHERE:4S, the Nashville To«~n Council has considered that such lighting creates glare, visual clutter and urban sky glow which can distract the attention of drivers of motor vehicles and thereby pose a significant risk for public safety; and ~?VHEREAS, the Nashville Town Council has received input from the public at large in duly noticed open meetings, and has considered and discussed the pros and cons of such regulation. NO~V THEREFORE, the Town Council of the Town of Nashville does ordain as follows; SECTION 1. DEFINITIONS Fixture -the assembly that holds the lamp (bulb} in a lighting system. It includes the elements designed to give light output control, such as a reflector (mirror) or refractor (lens), the ballast, housing, and the attachment parts. Full-cutoff (fco) -alight fixture which cuts off all upward transmission of light. Fully shielded -- a fixture with housing or attachment thereto which prevents a line of sight to the bulb l~~hen viewed from another property and l~~hich prevents a line of sight to any part of the light source at or above a horizontal plane running through the to«-~est portion of the fixture. IESNA -Illuminating Engineering Society of North America. Lumens -measure of brightness of the illumination exiting a bulb. Spotlight. - a luminaire or bulb which projects light in a specific direction in a narrow beam, typically 45 degrees or less. Sample Ordinance -Nashville, Indiana Page 2 Flood light - a luminaire or bulb «~hich projects light in a specific direction in a wide beam, typically 100 degrees or more. Glare -discomfort experienced by an observer with a direct line of sight to a light source which often results in annoyance, discomfort or loss of visual performance causing visual impairment. Horizontal (or vertical) foot-candles -the amount of light striking a vertical or horizontal plane. Light source -the bulb and lens, diffuser, or reflective enclosure. Light trespass -light projected onto a property from a fixture not located on that property. SECTION 2. REGULATION It is unlawful for any person, firm or corporation to install, erect or maintain any floodlight, searchlight, security light or other forni or type of light source within the limits of the Town of Nashville in such a manner that the light rays from such floodlight, searchlight, security light or other light source fail to conform with the tei7ns and conditions of this Ordinance. Further, it is unlawful for any person, firm or corporation to install, erect, or maintain any floodlight, searchlight, security light or other form or type of light source within the limits of the Town of Nashville in such manner that the light there from may distract the attention of any vehicle driver from the operation of a vehicle in a safe and prudent manner. On all properties except those zoned Rl and R2 the installation or replacement of any outdoor lighting fixtures shall require approval. Approval may not be issued unless the proposed installation is found by the Nashville Town Council to conform to all applicable provisions of this section. However, all properties within the To«7n of Nashville must comply with the terms of this Ordinance. SECTION 3. LIGHT TRESPASS The maximum illumination at five feet inside an adjoining residential parcel or public right-of- way or beyond, from an artificial light is 0.05 horizontal footcandles and 0.05 vertical footcandles. Said illumination likewise measured inside an adjoining commercial or industrial parcel or on a public roadway, or beyond, shall not exceed 0.1 horizontal footcandles or 0.1 vertical footcandles. No line of sight to a glaring light source is permitted from 5 feet or more inside a residential or public right-of-«~ay property line by an obseY-~~er vie«~ing from a position that is level ~~~ith or higher than the ground belo~~~ the fixture. Compliance is achieved with fixture shielding, directional control designed into the fixture, fixture location, fixture height, fixture aim, or a combination of these factors. SECTION 4. GENERAL LIGHTING DESIGN The bulbs in outdoor light fixtures emitting from 600 to 1200 lumens shall be frosted glass or covered by frosted glass or other similarly translucent cover. An outdoor fixture emitting more than 1200 lumens except motion detector activated lighting, shall be full cutoff and fully Sample Ordinance -Nashville, Indiana Page 3 shielded to an observer at the property line. This can be achieved with fixture location, mounting height, natural or artificial barriers on the fixture owner's property, fixture shielding, and other fixture design features. A spotlight of less than 1800 lumens need not be full cutoff or covered by a translucent cover if its center beam is aimed at a point not beyond any property lines and no higher than forty five degree below horizontal, and is motion detector activated and cycles off after five minutes. Generally, luminaires should not be located closer to the property line than a distance equal to three times the fixture's mounting height above grade at the property line. The use of search lights, laser lighting, or lights that pulse, flash, rotate or simulate motion for advertising or promotions is prohibited. Emergency lighting and traffic control lighting is exempt. Tower lighting shall not be permitted unless required by the FAA. Required lighting shall be of the lowest allowed intensity and red unless specifically forbidden under FAA requirements.

The ratio of the average illumination to the minimum illumination shall be 4:1. Lig ting of Exterior Display/Sales Areas: Lighting levels on exterior display/sales areas shall be adequate to facilitate the activities taking place in such locations. Lighting of such areas shall not be used to attract attention to the business. Signs allo~~ved under local Ordinance are to be used for the purpose. The applicant shall designate areas to be considered display/sales areas and areas to be used as parking or passive vehicle storage areas. This designation must be approved by the Town Council. i) Areas designated as parking or passive vehicle storage areas shall be illuminated in accordance «-~ith the requirements for parking areas suggested else«~here in this section. ii) Areas designated as exterior display/sales areas shall be illuminated so that the average horizontal illuminance at grade level is no more than 5.~ foot-candles. The ratio of average to minimum illuminance shall be no greater that 4:1. The average and minimum shall be computed for only that area designated as exterior display/sales area. iii) Light fixtures shall be cut-off fixtures, and shall be located, mounted, aimed, and shielded so that direct light is not cast onto adjacent streets or properties. Sample Ordinance -Nashville, Indiana Page 5 iv) Fixtures shall be mounted no more than 20 feet above grade, and mounting poles shall be located either inside the illuminated area or no more than ten (10) feet away from the outside edge of the illuminated area. Li ting of Walkways/Bikeways and Parks: t~'here special lighting is to be provided for walkways, bikeways, or parks, the following requirements shall apply. i) The walkway, pathway, or ground area shall be illuminated to a level of no more than 0.5 foot-candles. ii) The vertical illumination levels at a height of five (5}feet above grade shall be no more that 0.~ foot-candles. iii) Lighting fixtures shall be designed to direct light downward, and light sources shall have an initial output of no more than 1000 lumens. Lighting of Gasoline Station/Convenience Store Aprons and Canopies: Lighting levels on gasoline station/convenience store aprons and under canopies shall be adequate to facilitate the activities taking place in such locations. Lighting of such areas shall not be used to attract attention to the business. Signs allowed under local Ordinance are to be used for the purpose. i) Areas on the apron away from the gasoline pump islands used for parking or vehicle storage shall be illuminated in accordance with the requirements for parking areas set forth else~~vhere in this section. If no gasoline pumps are provided, the entire apron shall be treated as a parking area. ii) Areas around the pump islands and under canopies shall be illuminated so that the minimum horizontal illuminance at grade level is no more than 5.5 foot-candles. The ratio of average to minimum illuminance shall be no greater that 4:1. This yields an average illumination level of no more than 22.0 foot-candles. iii) Light fixtures mounted on canopies shall be recessed so that the lens cover is recessed or flush with the bottom surface of the canopy andlor shielded by the fixture or the edge of the canopy so that light is restrained to no more than 85 degrees beyond the vertical plane. iv) Lights shall not be mounted on the top or sides of the canopy, and the sides of the canopy shall not be illuminated. Lighting of Outdoor Facilities: Outdoor nighttime facilities (concerts, athletic contests, etc.) have unique lighting needs. Illumination levels vary, depending on the nature of the activity. The regulations in this section are intended to allow adequate lighting for such events while minimizing sky glow, reducing glare and unwanted illumination of surrounding streets and properties, and reducing energy Sample Ordinance -Nashville, Indiana Page 6 consumption. The design plan shall include a discussion of the lighting requirements of j=arious areas and how those requirements will be met. SECTI©N 5. SITE PLANS Outdoor lighting installations involving the installation or replacement of two or fewer lighting fixtures may be approved by the Town Manager, provided that no single lamp exceeds 150 watts, and that the total wattage of all bulbs in all fixtures does not exceed 300 watts. All other installations must be approved by the Town Council. The applicant shall submit to the Town sufficient information, in the form of an overall exterior lighting plan, to enable the Town to determine that the applicable provisions «~ill be satisfied. The lighting plan shall include at least the following items: i) A site plan, drawn to a scale of one inch equaling no more than t«~enty (20) feet, showing buildings, landscaping, parking areas, and all proposed exterior lighting fixtures. ii) Specifications for all proposed lighting fixtures including photometric data, designation as cut-off fixtures, and other descriptive information on the fixtures. iii) Proposed mounting height of all exterior lighting fixtures. iv) Analysis and illuminance level diagrams showing that the proposed installation conforms to the lighting level standards in this Ordinance. v) Drawing of all relevant building elevations showing the fixtures, the portions ofthe ~~~alls to be illuminated, the illuminance levels of the walls, and the aiming points for any remote light fixtures. Wherever practicable, lighting installations shall include timers, dimmers, and/or sensors to reduce overall energy consumption and eliminate unneeded lighting. t~'hen an outdoor lighting installation is being modified, extended, expanded, or added to, the entire outdoor lighting installation shall be subject to the requirements of this Ordinance. Expansions, additions, or replacements to outdoor lighting installations shall be designed to avoid harsh contrasts in color and~'or lighting levels. Electrical service to outdoor lighting fixtures shall be underground unless the fixtures are mounted directly on utility poles. Proposed lighting installations that are not covered by the special provisions in this Ordinance may be approved only if the To«~n Council finds that they are designed to minimize glare, do not direct light beyond the boundaries of the area being illuminated or onto adjacent properties or streets, and do not result in excessive lighting levels. In general IESNA standards shall be used to determine the appropriate lighting design. Sample Ordinance -Nashville, Indiana Page 7 For the purpose of these regulation, the mounting height of a lighting fixture shall be defined as the vertical distance from the grade elevation of the surface being illuminated to the bottom of the lighting fixture. The Town Council may modify the requirements of this section if it determines that in so doing, it will not jeopardize achievement of the intent of these regulations. SECTION 6. EZENIPTIONS The temporary use of low wattage or low voltage lighting for public festivals, celebrations, and the observance of holidays are exempt from this Ordinance except where they create a hazard or nuisance from glare. However, consideration to light trespass requirements shall be demonstrated prior to commencing the use of the temporary lighting. Commercial activities exempt under this provision of the Ordinance shall only be able to use this exemption for one occurrence per year.

V"OTE: 6 - d. RESULT: This Administrative Request for an additional section to the Zoning Code Section 153.149 was al~proved as presented in the draft ordinance writh minor modifications. It will be forwarded to City Council with an approval recommendation. STAFF CERTIFICATION ~,,~ m.c~ Jennifer M. Rauch, AICP Planner II Planning and Zoning Commission Minutes - 11/15/2447 Page 1 Exterior Lighting Requirements Administrative Request 07-109 ADNI Code Amendment Jenny Rauch said currently staff uses the Exterior Lighting Guidelines as the lighting proj=ision for ne~~~ developments. She said with recent development applications commercial and residential uses are located in close proximity to each other. She said concerns were raised from City Council, the Planning and Zoning Commission and residents of how the lighting will impact the surrounding areas. She said in an effort to address the concerns and formalize the standards Planning has created a new section within the Zoning Code for exterior lighting. She said the proposed language is di~~ided into four different sections: the purpose and intent, general requirements, site lighting requirements and administrative procedures. Ms. Rauch said the proposed language tries to balance proper illumination, ensure safety, but minimize glare and over lighting, as outlined in the purpose and intent. She said the general requirements section is the general overview as to when and where the lighting requirements apply. IVIr. Rauch said site lighting requirements identify more specifics, such as the types of shielding and fixtures needed to meet the requirements and ensure reasonable lighting levels. She said determining a maximum pole height for specific types of developments and the use of cut-off fixtures are some examples. Ms. Rauch said this section also outlines the reduction of parking lot lighting and sign illumination to 54% after 14 p.m. or one hour after the business closes ~~~hichewe~r is later. Ms. Rauch said the final section is the administrative portion which outlines the process and application requirements, similar to the current process. Kevin ~A~alter asked if the exceptions for holiday lighting have been addressed in the Code and if language can be added to emphasize that holiday lighting is only appropriate during a specific season. ~'arien Fishman said he is concerned about the ability to abuse the holiday lighting code. He said someone may deem any specific day as a `special' day to display holiday lighting. Mr. Langworthy said Planning can add wording stating there are appropriate seasons for holiday lighting. Chris Amorose Groomes asked if there is a requirement regarding illumination of outdoor staircases which are utilized after sunset. Nis. Rauch said that is not a requirement as part of the proposed Exterior Lighting Requirements. Mr. Langworthy said there should be lighting prior to the stairs and from the doorway which would illuminate the stairway. Mr. Amorose Groomes said any place which will have outdoor seating should be required that the steps are illuminated for safety purposes. Tammy Noble-Flading said she thought it would be a Building Code requirement. l~Ir. Langworthy said wording addressing that issue can be added to the Code. He said the issue would need to be dealt with on a case by case basis. Planning and Zoning Commission Minutes - 11/15/2447 Page 2 1VIr. Langworthy said the proposed language was reviewed by Police Department and from a safety point of view they would like everything to be well lit all of the time. Rick Gerber said some of the parking areas in Historic Dublin need to have more sufficient lighting for safety. Mr. Lang«~orthy said the intent is to haj=e parking lots lit during business hours. He said when the establishment closes for the night the parking lot lights will be reduced to 54%. N1r. Langworthy stated a public lot not in association with a particular business would remain lit at all times, unless Council states otherwise. 11i1r. Gerber said there is al«-ays a possibility of crime ~~~hen the lights are turned ofT. Mr. Walter said the UDF at Tara Hill is extremely dark due to lack of lighting; this can become a dangerous situation. He asked how this problem can be balanced. He said when the UDF was created the neighboring residents were very sensitive to lighting. IVIr. Walter said a balance needs to be established for safety reasons. Todd Zimmerman asked if a business closes at 7 p.m. are the lights going to remain on until 14 p.rn. Ms. Rauch responded yes. Mr. Langworthy said in order to enforce the Code a time had to be selected across the board. 1VIr. Walter asked how amulti-tenant facility would be handled. Mr. Langworthy said the last tenant would determine the time the lights are scaled back. Mr. Gerber asked if staff is expecting the proposed Code changes to be voted on this evening. Mr. Gunderman said if Commission is comfortable «~ith the proposed modifications as presented they can be voted on tonight. 11~Zotion and Vote I~Ir. Gerber made a motion to approve this Administrative Request for an additional section to the Zoning Code (Section 153.149) to govern exterior lighting. Mr. Zimmerran seconded the rnotion. The vote was as follows: Mr. Walter, yes; Mr. Fishman, yes; IV1r. Saneholtz, yes; Ms. Amorose Groomes, yes; N1r. Zimmerman, yes; 11~1r. Gerber; yes. (Approved 6 - 4.)

Request: RevieKT and recommendation for approval to City Council of new Code Section 153.149 Exterior Lighting Requirements under the provisions of Code Section 153.234. Applicant: City of Dublin, Jane S. Brautigam, City Manager. Planning Contact: Jennifer NI. Rauch, AICP, Planner. Contact Information: (614) 410-4690, jrauch@dublin.oh.us Case Summary This is a request for review and recommendation to City Council for a proposed addition to the Zoning Code to govern exterior lighting. The new Code Section provides for site lighting requirements, including fixtures, light trespass and pedestrian and landscape lighting, as well as administration procedures. Case Backbround: Currently, site lighting is governed by the City of Dublin Exterior Lighting Cruidelines. Planning is recommending that the Guidelines be updated and formally included in the Zoning Code to ensure their proper enforcement and effectiveness. Recent development has included a mix of uses, such as commercial, office and residential, located within close proximity, vThich has been met with some concerns from the Planning and Zoning Commission, City Council and residents regarding potential light pollution. While these projects have been approved with conditions aimed to address the concerns, the inclusion of Exterior Lighting Requirements within the Zoning Code titrill ensure that CityKride standards for site lighting are met and that light trespass is minimized. SECTION II - RE~'IE~V STAND_~RDS Case Procedure Code Section 153.234 grants City Council the ability to change or amend the text of the Zoning Code and Code Section 153.232(B)(2) grants the Plaruung and Zoning Commission the ability to review amendments to the Zoning Ordinance and reco7nrliend action to City Council. The Planning and Zoning Commission November 15, 2007 -Planning Report. Case No. 07-1091~D1v1-Page 2 of 2 purpose of this discussion is to revie«7 the proposed language for the Exterior Lighting Requirer~2ents and make a recommendation to City Council. Proposed Code Section The proposed Code Section is based on the existing Exterior Lighting Guidelines, but provides for more specific standards as a result of recent development. The new Code language is divided into four sections that include the overall purpose and intent and general requirements, as well as site lighting requirements and administrative procedures. The site lighting requirements identify the types of shielding and fixtures to ensure reasonable levels of lighting for security, but limit the levels of intensity to sun•ounding properties. In addition, the site lighting requirements outline the reduction of parking lot lighting to 54 percent and turning off of sign illumination to ensure that light trespass to surrounding properties is kept to a minimum after business hours. The administration portion outlines submission requirements and processes for existing lighting and modifications to exterior lighting follo~~~ing approval. SECTION III - RECOMl~~IENDATION: Recommendation for Approval to C"ity Council. In Planning's opinion, the additional Code Section outlines the requirements, and provides adequate guidance and enforcement for exterior lighting and a recommendation to City Council for approval is requested.
