55 - OUTDOOR LIGHTING AND BUILDING DESIGN
A.
Purpose. The outdoor lighting regulations of this section are intended to help ensure adequate lighting for motorized and nonmotorized travelers; provide for the efficient use of energy; and reduce the impacts of nuisance lighting and glare on nearby areas.
B.
Applicability and Exemptions. The outdoor lighting regulations of this section apply to all outdoor lighting installed after the effective date specified in 17.05.020, unless otherwise specified herein, except that they do not apply to any of the following:
1.
Other than Section 17.55.010.C.4, outdoor lighting on lots occupied by residential buildings containing fewer than four dwelling units;
2.
Public street lights;
3.
Airport runway and aviation safety lights required by the FAA (e.g., warning lights on radio, communication and navigation towers);
4.
Spotlighting of official government flags, provided that spotlighting is contained within the area of the flag;
5.
Outdoor lighting used exclusively for and during public recreational activities, sporting events at stadiums and ball fields or other outdoor public spaces or venues;
6.
Outdoor lighting used for emergency equipment and work conducted in the interest of law enforcement or for public health, safety or welfare;
7.
Outdoor lighting in association with special events approved by the city commission;
8.
Outdoor lighting used for a temporary use lasting no more than ten days;
9.
Lighting fixtures with a light output of no more than one thousand lumens; and
10.
Temporary holiday light displays.
C.
General Standards. All outdoor lighting must comply with the following general standards:
1.
Canopy-Mounted Lights. Recessed fixtures must be used in all under-canopy lighting. No lamps, reflectors, refractors or focusing or diffusing may extend below the underside of the canopy surface.
2.
Shielding. Light sources must be concealed or shielded with cutoffs so that no more than two and one-half percent of the light emitted directly from the lamp or indirectly from the fixture is projected at an angle of more than ninety degrees above nadir and no more than ten percent of the light emitted directly from the lamp or indirectly from the fixture is projected at an angle of more than eighty degrees above nadir.
FIGURE 55-1: REQUIRED SHIELDING
3.
Spillover Light. Light trespass along the lot line of the subject property may not exceed 0.5 foot-candles when abutting an agricultural or residential zoning district and may not exceed 3.0 foot-candles when abutting any other zoning district or public right-of-way. Maximum illumination levels are measured three feet above grade or from the top of any opaque screening fence or wall along the property line.
4.
Residential lighting regulations pertaining to lighting located upon lots occupied by residential buildings containing fewer than four dwelling units:
a.
The location of the lighting fixture together with its cut-off angle shall be such that it does not directly shine on any public right-of-way or any other residential premises;
b.
It shall not have an off-site luminance greater than one thousand footlamberts; it shall not have an off-site luminance greater than two hundred footlamberts measured from any private property in a residential zone.
c.
Where on-site lighting is provided, the location of all light poles shall be indicated on the site plan, plat or survey;
d.
For sites smaller than five acres, the maximum height of a light pole, measured from the finished grade to the top of the pole, shall be twenty feet;
e.
For sites five or more acres, the maximum height of a light pole, measured from the finished grade to the top of the pole, shall be thirty feet.
f.
The regulations contained in this subsection shall take effect immediately after adoption by the city commission.
D.
Lighting Plans.
1.
General. Outdoor lighting plans demonstrating compliance with the standards of this section are required with the submittal of a site plan. If no outdoor lighting is proposed, a note must be placed on the face of the site plan indicating that no outdoor lighting will be provided. Applicants have two options for the format of the required lighting plan:
a.
Submit a lighting plan that complies with the fixture height lighting plan requirements of 17.55.010.D.2; or
b.
Submit a photometric plan demonstrating that compliance will be achieved using taller fixture heights, in accordance with 17.55.010.D.3.
2.
Option 1: Fixture Height Standard Lighting Plan. Option 1 (Fixture Height Standard Lighting Plans) establishes maximum light fixture heights but does not require submittal of a detailed photometric plan.
a.
Information Required. Fixture height standard lighting plans must include at least the following:
(1)
A scale drawing of the site with all outdoor lighting locations shown;
(2)
Fixture specifications, including catalog cut-sheets or generic standards;
(3)
Pole type and height of fixture;
(4)
Lamp type and size; and
(5)
Fixture mounting and orientation.
b.
Maximum Fixture Heights. Allowable heights of light fixtures must be measured from the light-emitting surface to finished grade at the base of the pole. Maximum allowed light fixture heights are based on the (ground-level) horizontal distance between the light fixture and any agricultural or residential zoning district or public right-of-way, as established in Table 55-1:
TABLE 55-1: MAXIMUM LIGHT FIXTURE HEIGHTS
3.
Option 2: Photometric Study. Under Option 2 (Photometric Study Lighting Plan) no maximum fixture heights are established, but applicants are required to submit a photometric study in sufficient detail to demonstrate that all applicable outdoor light standards will be met. The photometric study must include at least the following:
a.
A scale drawing of the site with all outdoor lighting locations shown;
b.
Fixture specifications, including catalog cut-sheets or generic standards;
c.
Lamp type and size;
d.
Fixture mounting heights, mounting orientation, and tilt angles if applicable; and
e.
A representative point-by-point illumination array for the site showing property lines and all off-site lighting impacts.
E.
Measurement of Illumination. Light levels must be measured with a direct-reading, portable light meter, calibrated annually by an independent laboratory regularly engaged in the calibration of such instruments. The meter's sensor must be located at the top of the visual screening fence or wall along on the property line (or at a height of three feet above finished grade at the property line if there is no fence or wall), aimed towards the subject property in horizontal position. Readings must be recorded after the value has stabilized. Measurements are made after establishment of darkness with the light sources to be measured illuminated, and then with those light sources extinguished. The difference between these two readings must then be compared to the maximum allowed illumination at the property line. In this way, contributions to light levels by the moon and other ambient light sources are eliminated and the light intensity from the subject light sources can be accurately determined.
(Ord. No. 2122-2019, § 3, 6-20-19; Ord. No. 2137-2020, § 2, 10-15-20).
A.
Applicability. The regulations of this section apply to all new construction of metal buildings and metal-clad buildings visible from and located on lots abutting arterial or collector streets. The regulations also apply alterations and remodeling of existing buildings that result in an increase the building's floor area by fifty percent or more.
B.
Buildings with Visible Roof Lines.
1.
Buildings that have a roof line visible from the abutting arterial or collector street (gable front) must comply with the following minimum regulations:
a.
Eaves and overhangs must extend at least twelve inches beyond the sidewall and be fully trimmed with gutter and down spouts.
b.
For buildings with an eave height of twelve feet or less, there must be a minimum four-foot overhang at the front of the building. For buildings with an eave height of more than twelve feet, there must be an overhang of at least six feet at the front of the building.
c.
The roof must have a minimum of a 3:12 pitch, and must have a twenty-year or greater color cladding finish.
d.
Each building must have either:
(1)
A brick or stone wainscot, at least thirty-five percent of sidewall height at the front of the building, and on any side of the building that is visible from an abutting arterial or collector street; or
(2)
A full stucco facade at the front of the building and on any side that is visible from an abutting arterial or collector street.
C.
Buildings without Visible Roof Lines.
1.
Buildings with a roof line that is not visible from the abutting arterial or collector street (parapet or mansard) must comply with the following minimum regulations:
a.
Eaves and overhangs must extend at least twelve inches beyond the sidewall and be fully trimmed with gutter and down spouts.
b.
There must be a four-foot covered porch on any arterial or collector street frontage, except above overhead style doors. Required covered porch areas must have an overhang of at least twelve inches at gable overhang.
c.
Each building must have either:
(1)
A brick or stone wainscot, at least thirty-five percent of sidewall height at the front of the building, and on any side of the building that is visible from an abutting arterial or collector street; or
(2)
A full stucco facade at the front of the building and on any side that is visible from an abutting arterial or collector street.
D.
Anti-Monotony. In order to promote a variety of building designs and as a means of providing visual interest and avoiding monotony, repetitive building facade designs are prohibited. Adjacent building facade designs must, at a minimum, differ from one another by at least four of the following eight design options:
1.
Surface material;
2.
Color of building;
3.
Reversed floor plans;
4.
Roofing styles;
5.
Variation and building heights;
6.
Location and shape of windows and doors;
7.
Variations in front porches, walls, etc.; or
8.
Variation in front setback (minimum five-foot variation).
(Ord. No. 2122-2019, § 3, 6-20-19).
