Project Summary: 
 
1. 
Brian Vaccaro, on behalf of Earl & Curley, is requesting a Special Use Permit (SUP) to facilitate 
the reconstruction of a static billboard into a digital billboard on the subject parcel. The applicant 
is applying for this SUP due to the existing billboard not meeting the 1,000’ spacing requirements 
from other billboards per MCZO 1403.3.1.A.1.B, with an existing billboard approximately 500’ 
west at the northeast corner of Country Club Dr. and Iron Avenue. It should be noted the existing 
billboard, in its current location, would also not meet this distancing requirement. The applicant 
is proposing to rebuild the billboard in the new location, approximately 29’ east from the west 
parcel line, in a ‘v’ shape to allow for added visibility along the Superstition Freeway right-of-way. 
The billboard will be 60’ from the eastbound on-ramp and 137’ from the eastbound travel lane. 
 
2. 
Available records show no existing permits or a Plan of Development on the subject site except 
for those relating to the existing billboard. The billboard had originally been erected in 1979 under 
permit 79-9724. Contemporary site aerials show the site currently being used for the storage of 
construction vehicles. Based on historical aerials, it appears that vehicles have been stored on 
the site since at least 1996. Staff would note that legally continuing this use would require 
additional entitlements unrelated to this application. The site otherwise contains no other 
structures except lighting and perimeter fencing. 
 
3. 
The billboard on the site 500’ west, APN 139-50-001Z, was legally non-conforming per entitlement 
LU20130064, but is now entitled under a CUPD, entitlement Z2022053. The CUPD overlay for that 
billboard allows a billboard separation distance of less than 1,000’. The staff report for the 2013 
entitlement indicates that that billboard had originally been built in 1982 under permit 82-5938. 
This means that the billboard on the subject site predates the billboard for which the distancing 
requirement is being requested. Billboards, at the time of permitting for the adjacent site billboard, 
were allowed to be 400’ from other billboards on the same side of a street.

Staff Analysis: 
 
12. 
Staff considers the applicant’s request for this special use permit for billboard digitization to be 
reasonable and consistent with the existing character along the Superstition Fwy. This site is 
surrounded by industrial uses and bordered by a freeway.  Areas closest to a freeway typically 
comprise the highest areas of intense commercial and industrial activity due to the accessibility 
of the transportation node and are therefore appropriate for the use proposed. Staff is also 
supportive of replacing the static billboard with a digital face billboard. It is staff’s opinion that a 
digital face billboard with light mitigation is preferable to a traditional illuminated billboard. The 
applicant submitted all documents required to meet public participation requirements.  Staff 
notified the City of Mesa about the request and received no comments.  Staff received no public 
opposition and reviewing agencies (Engineering and Environmental Services) have no objections 
to the request. 
 
 
 
Recommendation: 
 
13. 
Staff recommends the Commission adopt a motion recommending that the Board of Supervisors 
approve Z2023022 subject to the following conditions ‘a’ – ‘f’: 
 
a. 
Development of the site shall be in substantial conformance with the Site Plan entitled 
“Site Plan“, consisting of 1 full-size sheet, dated March 30, 2023, except as modified by 
the following conditions. Staff may determine slight refinements to remain in substantial 
conformance with the approved site plan.  Minor and major amendments to the site plan 
will be determined in accordance with Chapter 3 of the Maricopa County Zoning 
Ordinance. 
 
b. 
Development of the site shall be in substantial conformance with the Narrative Report 
entitled “SUP Application for Digital Conversion of an Existing Billboard”, consisting of 8 
pages, dated March 31, 2023, except as modified by the following conditions.

Z2023022 
Page 6 of 6 
c. 
The following standard shall apply: 
 
1. Minimum billboard separation distance: 505’ 
 
d. 
The following engineering conditions shall apply: 
 
1. 
Engineering review of planning and/or zoning cases is for conceptual design  
only. All development and engineering design shall be in conformance with  
Section 1205 of the Maricopa County Zoning Ordinance; Drainage Policies and  
Standards; Floodplain Regulations for Maricopa County; MCDOT Roadway  
Design Manual; and current engineering policies, standards and best practices  
at the time of application for construction. 
 
e. 
Noncompliance with any Maricopa County Regulation shall be grounds for initiating a 
revocation of this Special Use Permit as set forth in the Maricopa County Zoning 
Ordinance.  
 
f. 
The granting of this change in use of the property has been at the request of the applicant, 
with the consent of the landowner.  The granting of this approval allows the property to 
enjoy uses in excess of those permitted by the zoning existing on the date of application, 
subject to conditions.  In the event of the failure to comply with any condition, and at the 
time of expiration of the Special Use Permit, the property shall revert to the zoning that 
existed on the date of application.  It is, therefore, stipulated and agreed that either 
revocation due to the failure to comply with any conditions, or the expiration of the Special 
Use Permit, does not reduce any rights that existed on the date of application to use, 
divide, sell or possess the property and that there would be no diminution in value of the 
property from the value it held on the date of application due to such revocation or 
expiration of the Special Use Permit.  The Special Use Permit enhances the value of the 
property above its value as of the date the Special Use Permit is granted and reverting to 
the prior zoning results in the same value of the property as if the Special Use Permit had 
never been granted.

Introduction & Purpose of Request: 
 
This application seeks to change the illumination method of an existing Off-Site Sign 
(14’x48’; 672SF) from traditional lighting to the newly approved digital lighting.  The 
existing sign is located east of the southeast corner of the US-60 and Country Club 
Drive in the Mesa area of unincorporated Maricopa County. 
 
Clear Channel Outdoor (CCO) proposes a full removal of the existing off-site printed 
sign and the installation of a new off-site LED digital sign with 30’ V-shape in 
accordance with the Maricopa County Ordinance.  The height will not exceed 48’ per 
the Ordinance.

Description of Proposal: 
 
This SUP application is solely to convert an existing legal non-conforming off-site sign 
from a conventional lit printed billboard to a digitally LED illuminated billboard.  The new 
off-site sign will be in the V-shape and will include digital illumination on both the east 
and west face.  The digital panel will conform to all ordinance requirements regarding 
digital illumination, including hours of operation and duration.   
 
This SUP application is required due to the existence of another off-premise sign 
located approximately 505’ to the west, as shown below.  The sign to the west has been 
approved for digital and has been installed.

Relationship to Surrounding Properties: 
 
The subject property is located along the southern frontage of the US-60 in an industrial 
area.  The zoning and characteristics of the surrounding properties are as follows: 
 
North: 
US 60 Freeway 
South: 
Iron Avenue and LI zoned industrial property 
East: 
LI zoned industrial property 
West: 
C-3 CUPD and IND-2 zoned industrial property

3 | P a g e  
 
 
 
There is no residential with 150’ of the subject property, nor is there a park/school or 
rest area within 500’ of the subject property.  
 
When the Board of Supervisors approved a pathway for these non-conforming 
billboards to change illumination methods to digital, there was strong support for 
allowing digital. We see the location of the subject billboard as being right in line with 
the Supervisor’s vision for digital conversions. Indeed, we see this board as an ideal 
candidate for conversion.  
 
 
Location and Accessibility: 
 
The subject site is accessed by Iron Avenue. The billboard will be approximately 60’ 
from the on-ramp to the US-60 and approximately 137’ from the nearest eastbound lane 
on the US-60.   
 
Development Schedule: 
 
The new off-site sign will be constructed within 8-12 weeks of receiving permit. 
 
Digital Illumination 
 
As for the digital billboard face, the illumination level of the proposed digital face is 
tightly controlled by the County regulations. The lighting must be controlled (with a 
sophistical internal device) to automatically adjust to ambient conditions during the day 
and night and must be reduced to a maximum 300 NITS during evening hours. It must 
then be automatically and completely extinguished between the hours of 11:00 p.m. and 
sunrise. If for any reason the dimmer device malfunctions, the billboard illumination will 
be extinguished until the dimmer can be replaced.   
 
It is sometimes mistakenly assumed that digital billboards will produce more light at 
night than traditionally illuminated billboards. But this is not the case. That is partly 
because of the County’s strict regulations on digital billboards. The ambient light level 
around the proposed digital billboard will not vary significantly from that of a traditional 
billboard display. (In many cases it will be less.) Clear Channel will set the light levels to 
be appropriate for the surroundings.  Given this fact, the conversion from printed to 
digital at this location will not have an adverse impact.

4 | P a g e  
 
 
 
 
 
This is an industrial area, not a residential area. Moreover, it is along the US-60, where 
tens of thousands of cars travel, each shining bright headlights. The proposal will not 
rise above ambient conditions.  
 
 
 
 
Addition of Light Directional Technology 
 
We also propose to utilize a light directional product for the east and west panel of the 
proposed digital billboard structure to mitigate views of the billboard face from areas 
outside of the travel lanes of the freeway.  This technology employs additional louvers 
within the display to direct billboard illumination. The narrative below explains how the 
technology works. For a more detailed and technical explanation of how the technology 
functions, we have attached a narrative from the manufacturer.  
 
The light directional product we will incorporate employs physical limitations on the 
lighting, including additional vertical louvers and the specific orientation of the RGB 
LED’s. With this technology, the farther away a viewer moves to the left or right from 0 
degrees from center, the less light from the billboard face is visible.  
 
This technology can be seen employed in the images below. The images show that as 
the car with the mounted camera passes the intended viewing angle, the image 
illumination becomes increasingly less visible to the point where it appears that the 
billboard’s image is fully extinguished.  This additional louver technology allows us to 
target digital illumination much more precisely.

For an additional demonstration of how this technology works, scan the QR code to the 
right or go to:   
https://www.youtube.com/watch?v=2Lr3RrdZmPQ

6 | P a g e  
 
 
 
Screen clips of this video are shown below. As the drone moves to the right (i.e., west in 
this case), and further away from the target viewing angle on the 101 Freeway, the 
image of the billboard lessens very quickly, to the point where the billboard image 
appears to be completely extinguished.  
 
 
 
 
To be clear, this technology can only be added to billboards with digital internal 
illumination. If we are approved to convert the subject billboards to digital illumination, 
we will add this new light mitigation technology to both the east and west face.

7 | P a g e  
 
 
 
 
Our request to convert to digital illumination with additional louver control will create an 
improved situation for the surrounding area.  
 
Additionally, the LED digital technology allows Clear Channel to utilize the billboard face 
display for emergency and public service announcements (such as “Amber Alerts” and 
extreme weather conditions) whenever the need may arise.  The digital billboard will 
also be incorporated into a messaging “network” with other such signs to provide 
updated emergency and/or public service messages across the system.  
 
For example, note that in 2020 the following images ran on Clear Channel digital 
billboards in support of the Governor’s campaign to combat the pandemic.  
 
 
 
Digital illumination will result in a higher-quality viewing experience; it will be turned off 
at 11:00 PM each night its brightness is tightly controlled; it will allow for the use of light 
directional technology, which provide controls over extreme viewing angles that cannot 
be done with printed billboards; it provides small businesses in the area an opportunity 
to advertise on this effective medium; and it will create additional opportunities for Clear 
Channel to display important governmental messages (both emergency and 
non-emergency messages).  
 
Conclusion: 
 
Conversion to Digital changeable message technology will result in a high-quality 
viewing experience; it will be turned off at night; and it will provide the County with a 
medium for important governmental messages (both emergency and non-emergency 
messages).  
 
The reconstructed sign will be enhanced with architectural improvements that will 
improve its visual appearance.  This request will not result in any harm to the area. 
 
In our opinion, the Supervisors’ recent approval of a pathway to digital was intended for 
billboards like this one.

Key Considerations for 
Light Trespass Mitigation.
Blocking and Non-blocking sides
In the majority of applications, MRI has found that light trespass mitigation is only needed in one direction, 
rather than to both directions of the digital billboard face. Therefore, SITELINE-30 is designed with an asym-
metric design that has a blocking and non-blocking side. The blocking side is the direction where light trespass 
is to be controlled. Orientation-wise, we define the direction from the forward viewing position when looking 
at the face of the board, i.e. “right-blocking” means that the display will block light from emitting to your right 
side if you are viewing it from the front.
 
Optimal viewing region (>80%)
The optimal viewing region as the angular region in which the display visual quality is unaffected by blocking. 
It is important for advertising purposes that the intended viewer is kept mostly in the optimal viewing region. 
The period of time where the audience is not in the optimal viewing region should be considered and mini-
mized (and quantified where possible). In the best applications, the viewer should make the entire approach in 
the optimal viewing region, and only move into the transition region as they pass by the display during the last 
few seconds where the digital billboard is already at an oblique angle to the car direction. 
 
As a pleasant side-effect of the SITELINE light mitigation system, the visual contrast is actually typically greatly 
enhanced compared to standard models, therefore the optimal viewing region of a SITELINE display will fre-
quently look better than a standard digital display configuration.
 
We define the optimal viewing region typically on the blocking side as where luminance remains above 80%.
 
In our third generation of SITELINE-30, we’ve increased the optimal viewing region slightly on the blocking 
side and greatly increased it on the non-blocking side, thereby making it more ideal for the majority of situa-
tions where readability on the non-blocking side should be maximized.
 
Protected region (<10%)
The protected region is the angular region in which the luminance of the digital billboard has dropped to less 
than 10% of the forward direction. Without light trespass mitigation technology, the luminance typically does 
not drop to less than 10% until over 75 degrees off center. At 10% of the forward luminance, most applications 
will typically see such a drop in light trespass in those directions that the corresponding foot candles or lux will 
satisfy requirements. It is important to point out that it is infeasible to achieve this level of protection using only 
head-rotation on traditional displays because copy cannot be reasonably read at 75 degrees off center.
 
Terminal Protected Region (<1%)
For SITELINE light blocking technology, we achieve a terminal performance figure less than 1% of the normal 
luminance at a given range This effective negates any light trespass concerns from the billboard, making the 
billboard look completely off during the day-time, and at night-time providing a very faint silhouette of the 
copy as a result of small reflections. In the terminal protected region, no LEDs can project light directly to the 
viewer thereby satisfying language where projection of light is prohibited. Be conscientious however with the 
language and avoid commitments that the display cannot be seen, rather focusing that there will no light tres-
pass as measurable in foot candles or lux.
 
Version 3.0 of SITELINE-30 achieves a terminal protection region that is actually less than 0.5% of the forward 
view.

 Transition Region (80% to 10%)
The transition region is the single most critical consideration when deciding whether a site is suitable for 
SITELINE light trespass mitigation. It is an unavoidable/inevitable angular region in which the viewers will have 
a degraded view of the digital billboard, and yet the light trespass mitigation is also incomplete, rendering it 
non-ideal for protection. We say it is inevitable because light trespass mitigation is physical, and LED diodes 
are not perfect point sources, therefore it is impossible to cover the entire light emitting area on the diode 
instantly with any transition region.
 
Important features to consider in the transition region are 
a. uniformity of the image during transition. Since the physical blocking of LEDs is very sensitive to 
tiny mechanical variations, any deformation however slight in the louvers (due to heat, stresses or 
production imperfections) results in a blocky, quilted and uneven look on the display. Version 3.0 of 
SITELINE-30 has the most advanced handling of optical-mechanical tolerances to date and pro-
vides improved uniformity during transition.
 
b. color accuracy during transition. LED digital displays are made with independent red, green and 
blue LEDs. If a blocking system does not properly handle each primary colors, the result is a change 
in displayed content color in the transition region, essentially ruining the advertising copy as soon 
as the transition begins. SITELINE maintains the same color throughout all angles of the transition, 
reducing only the total luminance.
 
c. width of the transition region. The transition region is an unwanted physical limitation to be man-
aged. A well-designed light trespass mitigation system will address this by minimizing the angular 
width of the transition region, thereby increasing the number of applications where it is suitable, 
and maximizing both viewing time for the intended audience, and minimizing the light trespass 
outside of the intended audience. SITELINE has been tuned over several generations to continually 
reduce the transition region width as we recognize it to be a key metric of a successful light mitiga-
tion module design. We’ve improved from 16 to 11 to 10 degrees across three generations.
With the newest SITELINE product, it may be practical to deploy light trespass mitigation with only 10 de-
grees of angular separation between intended audience and areas requiring protection!
