FEBRUARY 2010 DRAFT COLLIERVILLE DESIGN GUIDELINES PAG E

F. LIGHTINGLighting plays an important role and can reinforce an image within a siteor along a corridor, or at an intersection when coordinated between sites. Light-ing serves to illuminate parking areas and pedestrian paths and may be used tohighlight architectural features and displays. Collierville takes a strong lead in

ensuring that developments do not install excessive lighting and that lightsources are shielded so that they only serve the specific function for which theywere intended. The intent of these guidelines are not to be inclusive of all of theTowns regulations about lighting. It will serve as a guide for design profession-als, Board of Mayor and Alderman, Design Review Commission, staff, develop-ers, and property owners by providing a checklist that can be used by the appli-cant during the Preliminary Site Plan process, and will ultimately produce a morecomplete Final Site Plan, which is reviewed administratively by staff. It providesguidance for those seeking approval of lighting as well as a guide for the Townto review lighting request. For complete information about Colliervilles Light-ing Regulations, see the Collierville Zoning Ordinance, Sec. 151.003 and151.190, herein referred to as, The Lighting Ordinance.

1. General Lighting Guidelines

Is the proposed lighting plan providing appropriate and desirable nighttimeillumination for all uses as well as relating it to the site promoting safety, andkeeping the minimum level necessary for safety?

Has light pollution control been applied to the proposed lighting to mini-mize the impacts of misdirected upward and trespass light?

Does the lighting plan coordinate with the landscape plan removing con-flicts between trees/landscape material and light fixtures?

Will all pedestrian areas be well lit? Has protection of adjoining neighboring uses been factored into the lighting

plan design; specifically verifying that the proposed lighting will not nega-tively impact the residents?

2. Architectural Lighting Guidelines

Has the lightingbeen designed to blend with the architectural and landscapethemes of the site by coordinating it with the design of light fixtures, othersite elements, architecture of the building, and with the lighting of surround-ing developments and public spaces?

Will the light poles will be a neutral color? Will the concrete bases of the light poles will not be painted? Are the anchor bolts will be concealed with a matching cover? Is the lighting illuminating the building facades for design purposes? If so,

vertical foot-candle calculations must be submitted for review per the Light-ing Ordinance. Only accent lighting used to enhance architectural characterof specific structural elements in a selective fashion and kept to a minimumis allowed.

3. Light Source Shielding

Will all light fixtures be shielded and directed from neighboring properties,sidewalks, pathways, driveways, or public rights-of-way in such a manneras to prevent distractions to traffic as required by the Lighting Ordinance?

Is there a canopy at this site such as a gasoline station canopy, an entrancecanopy, a bank or restaurant drive through canopy, an entrance canopy?If so, are the light fixtures proposed under the canopy fully recessed withthe bottom of the lens flush with the bottom of the canopy as required bythe Lighting Ordinance?

Is the lighting proposed for signage screened as required by the LightingOrdinance?

Are the pole mounted lights full cutoff fixtures? Are the buildingmounted lights (other than decorative only fixtures) cutoff or full cutofftype fixtures?

Are all fully shielded light sources ( full cut-off ) shielded so that lightemitted from the fixture, directly or indirectly, are projected below a hori-zontal plane through the lowest point of the fixture where light is emitted?

Are all flood light lamp sources shielded by using barn doors, glareshields, fixed hoods, or grid louvers?

Are the decorative wall mounted fixtures have the lamp source shielded asrequired by the Lighting Ordinance?

Are the lights used for illuminating a sign are aimed and shielded so thatdirect illumination is focused exclusively on that sign? Top down mount-ing of lighting fixtures is acceptable.

4. Light Fixture Height

Are the building-mounted light fixtures and the free-standing light fixturesare in proportion with the building and do not exceed the building height?All freestanding light fixtures proposed to exceed the height of the build-ing shall be noted and have been submitted as a special case for approval.For example, in a development with multiple buildings of various heights,fixture height may be permitted to exceed the height of the shortest build-ing because providing the same fixtures throughout the development maybe more appropriate than limiting fixture heights to the height of eachindividual building.

Are all pedestrian areas lighted with appropriately scaled poles and lumi-naries that are typically ten (10) to fourteen (14) feet?

Are any ground-oriented, pedestrian-scale lighting used as an alternative tostandard pole-mounted fixtures along pedestrian paths to parking lots andother destinations?

5. Decorative Architectural Lighting of Buildings, Arbors, Land-scaping, and Similar Features

Will there be decorative lighting other than holiday decorating lighting,which is considered to be illuminated tubing or strings of lights outlining

property lines, rooflines, or wall edges of buildings? Such lights, if notprohibited, will include string lighting, added to arbors, pergolas, betweenbuildings over pedestrian ways and outdoor seating areas, and will be re-viewed on a case-by case basis.

Will all decorative architectural lighting be selected, located, aimed andshielded so that direct illumination is focused exclusively on the buildingfaade, plantings, and other intended site feature and away from adjoiningproperties and the public street right-of-way?

6. Sports Lighting

If sports lighting is proposed, has it been furnished with glare controlwith the lighting fixtures, mounted, and aimed so that illumination falls

within the primary playing field and immediate surroundings so that nodirect light illuminations is directed off site? All sports/recreational light-ing will be reviewed on a case-by-case basis.

Does the mounting height of outdoor sports field and outdoor perform-ance area lighting fixtures exceeding eighty (80) feet from finished grade?

Is there a note on the plans that outdoor recreational facility/outdoor per-formance facility is illuminated after 11:00 PM except to conclude recrea-tional activity or performance conducted at the facility prior to 11:00 PM.

7. Exempt Lighting

Individual residential lighting is not reviewed as part of a site plan. Lighting associated with permitted temporary uses, provided that the light-

ing meets standards of this ordinance.

Temporary outdoor light fixtures used as holiday decoration provided perSec. 151.175(Q) Holiday Lighting.

Government facility lighting necessary for public safety. All outdoor fossil fuel lighting producing light directly from the combus-

tion of fossil fuels.

Emergency lighting, provided the use of said lighting is temporary anddiscontinued immediately upon abatement of the emergency necessitatingsaid lighting.

Underwater lighting used for illumination of swimming pools and foun-tains.

8. Fixture Style

Fixtures shown within these Guidelines that are identified with by (T) are ap-propriate fixture styles in Traditional Areas and those by (C) are consideredappropriate fixture styles in Conventional Areas. Traditional-style fixtures areconsidered appropriate everywhere in town.

9. Technical Provisions

Are light corridors provided per Section 1006 of the 2003 InternationalBuilding Code? These light corridors have been measured from each exitused as a means of egress from a building to a public way have been pro-

vided with a minimum width of 10 feet and a minimum of 1.0 footcandlemeasured at ground level as Will the accent lighting and sign illuminationbe incandescent, LED, or compact fluorescent as allowed. Are all the pro-posed outdoor lighting metal halide?

Will the accent lighting and sign illumination be incandescent, LED, orcompact fluorescent as allowed.

Is the same light source used for the same or similar types of lighting onthe site/development?

Will the parking lot lighting and building lighting be metal halide? Is the wiring for outdoor lighting concealed? Does the proposed lighting meet the minimum Illuminating Engineering

Society (IES) standards, and not exceed 200% of the recommended val-ues?

Does all parking lot lighting proposed comply with the standards in Table151.190-03, Parking Lot Lighting Levels and Table 151.190.02, MaximumSpillover in foot candles of the Lighting Ordinance.?

Does the lighting plan maintain the uniformity in light levels across thesite/development and prevents or minimize dark areas? The ratio of maxi-mum to minimum lighting levels on a given site or parcel of land as meas-ured in foot-candles at ground level, shall not exceed twenty-to-one (20:1)in residential developments or fifteen-to-one (15:1) in nonresidential andmixed-use developments. Some high security areas such as ATMs, ve-hicular canopies may need to be calculated separately. Furthermore large

landscape areas that are non-illuminated may need to be calculated sepa-rated to maintain the uniformity.

Are the light pole fixtures height and building fixtures height withinproximity of residential districts located per TABLE 151.190.02?

Are wall pack lights used only to light unsafe service areas and are not in-tended to draw attention to the building or provide general building or sitelighting?

Is the lighting proposed under a vehicular canopy, considered a high secu-rity area, exceed an average of 20 foot-candles?

Does the owner/developer/builder understand that a final letter of certifi-cation from the lighting engineer, qualified lighting professional, or light-

ing manufacturer will be submitted to the Town verifying that all site light-ing is installed on the site according to Town standards, the approvedplans, and any applicable conditions before certificates of occupancy arereleased?
