not exceed 100 nits.
(Ordinance 475 adopted 6/28/22)
A.
For all High-Density Residential, Non-Residential, and Mixed-Use
zoning districts (zoning districts R-4, R-5, MU-N, MU-C, MU-TC, CR,
P, and PDDs with one or more allowed uses consistent with these districts)
or any residential development other than Single-Family Residential
with seven residential units or more and having common outdoor areas,
all outdoor lighting shall comply either with 6.2.4, Prescriptive
Method of Regulatory Compliance or 6.2.5, Performance Method of Regulatory
Compliance. Two methods are provided for assessing regulatory compliance:
1.
Prescriptive method.
(i)
The Prescriptive Method of Regulatory Compliance contains precise
and easily verifiable requirements for luminaire light output and
fixture design that limit glare, upward projected light (uplight),
light trespass, and the amount of light that can be used.
(ii)
The prescriptive method constrains total installed
initial luminaire lumens based on compliant luminaires and project
property conditions and features.
(iii)
The prescriptive method is most suitable for
outdoor lighting projects that do not involve a lighting professional
because they are simple and do not require engineering expertise.
2.
Performance method.
(i)
The performance method allows greater flexibility and creativity
in meeting the intent of this Section 6.2, Lighting.
(ii)
The performance method establishes system performance
metrics for the system as a whole detailing photometric calculations
in addition to individual luminaire compliance.
(iii)
An engineer or lighting professional generally
will be required to design within the performance method.
(iv)
The performance method is most suitable for projects
with the following characteristics:
(1)
Lighting must be evaluated under complex requirements
not suitable under the Prescriptive Method;
(2)
The applicant wants or needs more flexibility in
lighting design;
(3)
The lighting designer plans to aim or direct any
light fixture upward (above 90 degrees); or
(4)
The project requires higher lighting levels compared
to typical area lighting.
(Ordinance 475 adopted 6/28/22)
A.
Total site lumen limit. The total installed initial luminaire lumens
of all outdoor lighting shall not exceed the total site lumen limit.

Area Method).
2.
Only one method shall be used per permit application, and for
sites with existing lighting, existing lighting shall be included
in the calculation of total installed lumens.
3.
The total installed initial luminaire lumens is calculated as
the sum of the initial luminaire lumens for all luminaires.
B.
Limits to off-site impacts. All luminaires shall be rated and installed
according to subsection 6.2.9, Lighting Design Standards and Metrics.

(Ordinance 475 adopted 6/28/22)
A.
Total site lumen limit. The total installed initial luminaire lumens
of all lighting systems on the site shall not exceed the allowed total
initial site lumens. The allowed total initial site lumens shall be
determined using the applicable metric listed in subsection 6.2.9,
Lighting Design Standards and Metrics. For sites with existing lighting,
existing lighting shall be included in the calculation of total installed
lumens. The total installed initial luminaire lumens of all luminaires
is calculated as the sum of the initial luminaire lumens for all luminaires.
B.
Limits to off-site impacts. All luminaires shall be rated and installed
using one of the options below:
1.
Categorical assessment option. All luminaires shall be rated
and installed according to Section 6.2.2.
2.
Software modeling option. The entire outdoor lighting designs
shall be analyzed using industry standard lighting software including
interreflections in the following manner:
(i)
Input data shall describe the lighting system including luminaire
locations, mounting heights, aiming directions, and employing photometric
data tested in accordance with IES guidelines. Buildings or other
physical objects on the site within three object heights of the property
line must be included in the calculations.
(ii)
Analysis shall utilize an enclosure comprised
of calculation planes with zero reflectance values around the perimeter
of the site. The top of the enclosure shall be no less than 33 feet
(10 meters) above the tallest luminaire. Calculations shall include
total lumens upon the inside surfaces of the box top and vertical
sides and maximum vertical illuminance (Footcandles or lux) on the
