7. UNFINISHED BUSINESS A. OUTDOOR LIGHTING (MCLEAN)

Commissioner Nuttbrock summarized the proposed changes made to the city engineering standards for street illumination. The recommendation is to not allow new low-pressure sodium lights. LED lighting standards will be specified by road classifications; i.e. local, collector, arterial, etc.

The Commissioners came to the general consensus that limited up-lighting could be allowed on pedestrian oriented streets within commercial zoning districts because the potential height of commercial structures may block glare.

The Commissioners agreed that it is important to get feedback from the community. To the extent feasible, the Commissioners would like the City to install sample light fixtures within one test site to allow the public an opportunity to identify the ideal

environment in the interest of public safety. d. Help protect the natural environment from the adverse efects of artfcial night

lightng.e. Conserve energy and resources to the greatest extent possible.

II. Lightng ZonesThe Lightng Zone shall determine the limitatons for lightng as specifed in this Ordinance. Lightng Zones as discussed below are intended to be descriptve, but not defnitve. The Lightng Zones shall be construed to mean the following:

LZ-0: No ambient lightng – Habitat/Critcal AreasAreas where the natural environment will be seriously and adversely afected by lightng. Impacts include disturbing the biological cycles of fora and fauna and/or detractng from human enjoyment and appreciaton of the natural environment. Human actvity is subordinate in importance to nature. The vision of human residents and users is adapted to the darkness, and they expect to see litle or no lightng. When not needed, lightng should be extnguished.

LZ-1: Low ambient lightng – Residental DistrictAreas where lightng might adversely afect fora and fauna or disturb the character of the area.The vision of human residents and users is adapted to low light levels. Lightng may be used for safety and convenience but it is not necessarily uniform or contnuous. Afer curfew, most lightng should be extnguished or reduced as actvity levels decline.

LZ-2: Moderate ambient lightng – Commercial DistrictsAreas of human actvity where the vision of human residents and users is adapted to moderate light levels. Lightng may typically be used for safety and convenience but it is not necessarily uniform or contnuous. Afer curfew, lightng may be extnguished or reduced as actvity levels decline.

LZ-3: Moderately high ambient lightngAreas of human actvity where the vision of human residents and users is adapted to moderately high light levels. Lightng is generally desired for safety, security and/or convenience and it is ofen uniform

Lighting Code

Attached are my current drafts of the city engineering standard for street lights and the new lighting code. I suggest we continue our review of these two documents at our meeting next week. I have not made as much progress on these as I had hoped and I will be gone next week so I probably will not make any more progress.

For the engineering standard we still need to get confirmation from CPU that they will support the luminaries that we are proposing. I’ve had several email conversations with Tony Cooper on this subject. Holophane recently won the CPU contract to supply street lights. Tony committed to checking with CPU on which Holophane luminaries were in their bid. I have not heard back from him.

The attached lighting code is my current proposed draft. As we discussed at our last meeting, I used the IES MLO lite model code as the starting point for our code. The text highlighted in red is text that modified substantially or text I’ve incorporated from the POLC. Here are some of the changes I made:

1. I’ve restructured the MLO Lite to conform to our LCMC format. At Eric’s suggest, this will be a newchapter in Title 18 - LCMC 18.282. I’ve included a definitions section, but we’ll need to decide if wewant to include the definitions in LCMC 18.40, Definitions, or leave them within LCMC 18.282. I’musing the convention of italicizing word that included in the definitions list.

2. I’m proposing we use only the first three less bright lighting zones from the MLO Lite. I’ve assignedcity zoning districts to the lighting zones. All of the lighting levels for these zones are unchanged fromthe MLO Lite.

3. In the Hardscape Area Method for non-residential lighting I’ve added an additional illuminationallowance for our Pedestrian-Oriented Streets and Pedestrian-Oriented Spaces - see Table 18.282.2.This is to ensure these areas have adequate lighting to create an attractive and inviting environment.We’ll need to discuss the appropriate lumens for these standards.

4. I’ve added backlight BUG rating requirement that was not included in the MLO Lite. For Pedestrian-Oriented Streets and Pedestrian-Oriented Spaces I’m allowing more uplighting that allowed in otherareas and again the intent is to enhance the pedestrian environment. See Table 18.282.4.

(g) Hardscape means permanent improvements to a site including (but not limited to) parking lots, drives, entrances, curbs, ramps, stairs, steps, medians, walkways and non-vegetated landscaping that is ten (10) feet or less in extent measured away from edges ofstructures. Hardscape materials may include concrete, asphalt, stone, gravel and similar substances.

(h) Hardscape Area means the area measured in square feet of all hardscape. It is used to calculate the Total Site Lumen Limit.

(i) Illuminance means the quantity of light striking a surface, which varies with distance and angle. Also known as luminous flux density.

(j) LED means Light Emitting Diode.

(k) Light Pollution means any adverse effect of artificial light including, but not limited to: glare, light trespass, sky-glow, energy waste, compromised safety and security, and impacts on the nocturnal environment.

(l) Light Trespass means any light that falls beyond the legal boundaries of the property it is intended to illuminate.

(m) Initial Lumens means the total luminous flux of luminaire assuming it is new and not subject to diminution of light output due to age or condition.

(n) Lumen (lm) means a unit of luminous flux used to quantify the amount of light produced by a lamp or emitted from a luminaire that is independent of the distance between the lamp and the viewer. If a light source emits one candela of luminous intensity uniformly across a solid angle of one steradian, the total luminous flux emitted into that angle is one lumen.

(o) Luminaire means the complete lighting unit (fixture), consisting of a lamp, or lamps and ballast(s) (when applicable), together with the parts designed to distribute the light (reflector, lens, diffuser), to position and protect the lamps, and to connect the lamps to the power supply. The lumen rating of a luminaire assumes the lamp or luminaire is new and has not depreciated in light output; see Initial Lumens.

(p) Nadir means the local direction corresponding to the vector between any point on the surface on the Earth and the center of the Earth, which may be visualized with the use of a plumb bob.

(q) Pedestrian-Oriented Space means a public outdoor space intended to feature a concentration of commercial and pedestrian activity. Such spaces feature have a

pedestrian scale and feature multiple pedestrian amenities such as benches and tables, artwork, drinking fountains, decorative waste receptacles, bicycle racks, landscaping, andfountains. Pedestrian-Oriented spaces may include plazas, court yards, or parkways. A Pedestrian-Oriented Space shall be specifically designated by the review authority.

(r) Pedestrian-Oriented Street means a street intended to feature a concentration of commercial and pedestrian activity. Such streets feature multiple pedestrian amenities, pedestrian scale features, slow moving traffic, narrow travel lanes, limited on-street parking, wide sidewalks. A Pedestrian-Oriented Street shall be specifically designated by the review authority.

(s) Skyglow means the brightening of the nighttime sky that results from scattering and reflection of artificial light by moisture and dust particles in the atmosphere and has the effect of reducing one's ability to view the night sky.

(t) Uplight means the luminous flux radiated in the hemisphere at or above the horizontal plane defined perpendicular to the nadir direction at the photometric center of exterior luminaire.

2.27 Street Illumination

A. Plats and Short Plats.

Street lighting is required for all public streets. The street lighting design shall bereviewed and approved by the Engineer prior to final plat approval. The cost of allstreet lighting shall be paid for by the developer.

Street lighting is not required on private streets within a plat. However, a streetlighting system is encouraged. The City does not install or maintain private streetlighting systems. On private streets, all street light maintenance and power cost shallbe paid by the developer, homeowner, or homeowners association.

B. Existing Residential Areas.

If a resident or group of residents desires the installation of a new street light they must apply to the Public Works Director.

C. Commercial.

Street lighting is required on all public street frontages. The developer is responsiblefor design, installation or relocation of new or existing lighting. Commercialdevelopment shall replace existing lighting systems on power poles with a newlighting system serviced by underground power if the system will not conflict withessential distribution lines.

D. General Considerations.

All public street light designs shall be prepared by a licensed engineer experienced inlighting design. The design calculations should indicate illuminaire spacing,illumination levels, uniformity ratio, line losses, and the electrical and physical layoutof the system, including its connection to the existing system.

All public street light systems shall be accessible for public maintenance by a wheeled vehicle weighing twenty-thousand pounds (20,000 lbs.).

All street light installations including wiring, conduit, and power connections shall belocated underground. Exception: existing residential areas with existing above groundutilities may have street lighting installed on the existing power poles with approvalfrom the lighting authority.

As-built drawings on (22") x (34") mylar and in AutoCAD .dwg format are required for all new or relocated underground street lighting systems prior to receiving a final occupancy permit.

All street lights shall be on two-hundred and forty (240v) volt single phase systems. Howabout solar lights. The exact location of the power source should be indicated togetherwith the remaining capacity of that circuit. System continuity and extension should beconsidered.

Contractor cabinets equipped with electrical meters, time clocks, circuit breakers andother required components are required on commercial installations of five (5) or morestreetlights.
