A.

Generally. The purpose of this Article is to set out regulations for the erection and maintenance of signs while preserving the right of free speech and expression.

B.

Objectives. The objective of the regulations of this Article is to provide a balanced and fair legal framework for design, construction, and placement of signs that:

1.

Promotes the safety of persons and property by ensuring that signs do not create a hazard by:

a.

Collapsing, catching fire, or otherwise decaying;

b.

Confusing or distracting motorists; or

c.

Impairing drivers' ability to see pedestrians, obstacles or other vehicles, or to read traffic signs; and

2.

Promotes the efficient communication of messages, and ensures that persons exposed to signs:

a.

Are not overwhelmed by the number of messages presented; and

b.

Are able to exercise freedom of choice to observe or ignore said messages according to the observer's purpose; and

3.

Protects the public welfare and enhances the appearance and economic value of the landscape by protecting scenic views and avoiding sign clutter that can compromise the character, quality, and viability of commercial corridors;

4.

Ensures that signs are compatible with their surroundings, and prevents the construction of signs that are a nuisance to occupants of adjacent and contiguous property due to brightness, reflectivity, bulk, or height;

5.

Promotes the use of signs that are aesthetically pleasing, of appropriate scale, and integrated with the built environment, in order to meet the City's Comprehensive Planning objectives related to the quality and character of development;

6.

Enhances property values and business opportunities;

7.

Assists in wayfinding; and

8.

Provides fair and consistent permitting and enforcement.

C.

Authority. The City Council finds that:

1.

The City has the authority to regulate signs under the United States Constitution, the Constitution of the State of Colorado, and the Home Rule Charter of the City of Centennial;

2.

This Article advances important and substantial governmental interests;

3.

The regulations set out in this Article are unrelated to the suppression of constitutionally-protected free expression and do not involve the content of protected messages which may be displayed on signs, nor do they involve the viewpoint of individual speakers;

4.

The incidental restriction on the freedom of speech is no greater than is essential to the furtherance of the interests protected by this Article; and

5.

Certain types of speech are not protected by the First Amendment due to the harm that they cause to individuals or the community, and speech that is harmful to minors may be prohibited in places that are accessible to minors.

D.

General Findings of Fact. The City Council finds that:

1.

The ability to display signs of reasonable size and dimensions is vital to the health and sustainability of many businesses, and the display of signs with noncommercial messages is a traditional component of the freedom of speech, but the constitutional guarantee of free speech may be limited by appropriate and constrained regulation that is unrelated to the expression itself;

2.

The City has an important and substantial interest in preventing sign clutter (which is the proliferation of signs of increasing size and dimensions as a result of competition among property owners for the attention of passing motorists), because sign clutter degrades the character of the community, makes the community a less attractive place for commerce and private investment, and dilutes or obscures messages displayed along the City's streets by creating visual confusion and aesthetic blight;

3.

Sign clutter can be prevented by regulations that balance the legitimate needs of individual property owners to convey their commercial and noncommercial messages against the comparable needs of adjacent and nearby property owners and the interest of the community as a whole in providing for a high quality community character;

4.

Temporary signs that are not constructed of weather-resistant materials are often damaged or destroyed by wind, rain, and sun, and after such damage or destruction, degrade the aesthetics of the City's streets if they are not removed;

5.

The City has an important and substantial interest in keeping its rights-of-way clear of obstructions and litter;

6.

The City has an important and substantial interest in protecting the health of its tree canopy, which contributes to the character and value of the community; and

7.

The uncontrolled use of off-premises outdoor advertising signs and their location, density, size, shape, motion, illumination and demand for attention can be injurious to the purposes of this Article, and destructive to community character and property values, and that, as such, restrictions on the display of off-premises commercial messages are necessary and desirable.

A.

Generally. Hereinafter, all construction, relocation, enlargement, alteration, and modification of signs within the City shall conform to the requirements of this Article, all State and Federal regulations concerning signs and advertising, and applicable building codes. Generally, signs are approved by issuance of a sign permit. However, there are some signs that do not require a permit. These signs are listed in subsection C., below.

B.

Signs Requiring a Permit. A sign permit shall be required for all permitted signs exceeding six square feet in area, unless otherwise exempted by subsection C., below. In addition, a sign permit shall be required at any time the sign area is increased, if the increase is allowable within the zone district in which the sign is located. This subsection shall not be interpreted so as to grant permission for prohibited signs with sign areas less than six square feet.

C.

Signs that Do Not Require a Sign Permit. The following signs do not require a sign permit, but may require a building permit or other related permit (if subject to building or electrical codes). Temporary signs that do not require permits shall still comply with the standards of Division 6-5, Temporary Signs, and Division 6-3, General Design and Maintenance Standards, or the applicable standards of this subsection.

1.

Official and Legal Notice. Official and legal notice signs that are issued by any court, public body, person, or officer in performance of a public duty, or in giving any legal notice, including signs that are required to be posted to give notice of pending action pursuant to this LDC.

2.

Signs with De Minimus Area. Signs that are affixed to a building or structure (even if wall signs are not permitted in the district or for the use), which do not exceed one square foot in sign area, provided that only one such sign is present on each elevation that is visible from public rights-of-way or neighboring property; and signs that are less than three-fourths of a square foot in area that are affixed to machines, equipment, fences, gates, walls, gasoline pumps, public telephones, or utility cabinets.

D.

Exemption for Addressing. The City Council finds that the posting of the addresses of buildings in locations that are visible from the street is necessary for the effective delivery of public safety services, including E-911. The efficient and timely delivery of emergency services is a compelling governmental interest. Accordingly, the City requires that street addresses shall be posted as follows:

1.

Nonresidential and Mixed-Use Districts. In nonresidential districts, street addresses shall be posted at:

a.

All primary building entrances; and

b.

On detached signage if the address on the building is not visible from the street.

2.

Residential Districts. In residential districts, street addresses shall be posted:

a.

On the façade of the building that faces the street from which the address is taken; and

b.

On the mailbox or mailbox support, if the mailbox is detached from the building.

3.

Exclusion from Sign Area Calculation. Because address signs are required, numbers and letters used for addressing are not included in the calculation of sign area if they are not more than 14 inches in height.

E.

Exemption for City Branding/Wayfinding Signs. City Branding/Wayfinding Signs, as defined by this LDC, that are included within an approved City-wide Branding and Wayfinding Sign Plan are exempt from standards and regulations found in Division 6-4, Permanent Signs.

F.

Exemption for City Installed Murals. City Installed Murals, as defined by Section 12-6-102(C)(11) are exempt from standards and regulations found in Division 6-4, Permanent Signs.

G.

Signs Permitted Before Effective Date. If a permit for a sign has been issued in accordance with all City ordinances in effect prior to the effective date of this Article, and provided that construction is begun within six months of the effective date of this Article and diligently pursued to completion, said sign may be completed in accordance with the approved plans on the basis of which the permit has been issued, subject thereafter, if applicable, to the provisions of this LDC regarding nonconforming signs.

H.

Relationship to Other Regulations. These Regulations recognize other regulations pertaining to signage (i.e., State of Colorado, Department of Highways, "Rules and Regulations Pertaining to Outdoor Advertising," effective January 1, 1984, and as may be amended). Where any provision of this Article cover the same subject matter as other regulations, the more restrictive regulation shall apply.

(Ord. 2023-O-14 §§2, 3; Ord. 2024-O-18 §§2—4)

A.

Generally. The regulations of this Article shall be applied using the measurements set out in this Section.

A.

Generally. The calculations required by the regulations of this Article shall be according to the methodologies of this Section.

B.

Sign Area.

1.

Generally. Sign area is calculated as the area within a continuous perimeter with up to eight straight sides that encloses the limits of text and graphics of a sign, together with any frame or other material or color forming an integral part of the display or used to differentiate the sign's message from the background against which it is placed. The area excludes the structure upon which the sign is placed (unless the structure is an integral part of the display or used to differentiate it), but includes any open space contained within the outer limits of the display face of a sign, or between any component, panel, strip, or figure of any kind composing the display face, whether this open space is enclosed by a frame or border or not. See Figure 12-6-202A, Sign Area, Generally.

Expand

Figure 12-6-202A Sign Area, Generally
The sign area (shown as the blue outline of blue in Figure 12-6-202A) of the illustrative monument sign below is calculated as the area within the smallest eight-sided polygon that encloses all of the text and graphics and framing of the message and graphics of the sign.
The sign area (shown as the blue outline of blue in Figure 12-6-202A) of the illustrative collection of wall signs below is measured as the area within the smallest eight-sided polygon that encloses all of the text and graphics and framing that differentiates them from the wall.

 

2.

Double-Faced Signs. For projecting, suspended, or other double-faced signs:

a.

Only one display face is measured if the sign faces are parallel or form an interior angle of less than 45 degrees, provided that the signs are mounted on the same structure. If the faces are of unequal area, then sign area is equal to the area of the larger face.

b.

Both display faces are measured if:

i.

The interior angle is greater than 45 degrees; or

ii.

The sign faces are mounted on different structures.

Expand

Figure 12-6-202B Double-Faced Signs

 

C.

Signable Area. Signable area is calculated as follows:

1.

Wall Signs. A two-dimensional area on the façade of a building that describes the largest square, rectangle, or parallelogram which is free of architectural details.

2.

Window Signs. The area of glass within a window frame.

3.

Other Signs. The area of the face of the sign which is designed to be used for text and graphics (the signable area does not include the sign's supporting frame or structure, if any, provided that such frame or structure is not designed to display text or graphics).

Expand

Figure 12-6-202C Signable Area
Signable area is shown as the red outline in Figure 12-6-202C.

 

D.

Signable Area Ratio. Signable area ratio is the sign area divided by the signable area. It is expressed as a percentage.

Expand

Figure 12-6-202D Signable Area Ratio
Signable area ratio is the sign area (outlined in blue in Figure 12-6-202D) divided by the signable area (outlined in red in Figure 12-6-202D). It is expressed as a percentage.

 

E.

Relationship Between Maximum Sign Area and Maximum Signable Area Ratio. Where both a maximum sign area and a maximum signable area ratio are set out, the standard that results in the least sign area applies.

(Ord. 2024-O-18 §§5—7)

3.

Illumination Standards. The illumination standards set forth in this subsection B.3. shall apply to all electronic message center signs, including multi-tenant electronic message centers.

a.

Measurement Criteria. The illuminance of an electronic message center shall be measured with an illuminance meter set to measure foot-candles accurate to at least two (2) decimals. Illuminance shall be measured with the electronic message center off, and again with the electronic message center displaying a white image for a full color-capable electronic message center, or a solid message for a single-color electronic message center. Measurements shall be taken after sunset with the site fully illuminated by installed site lighting. All measurements shall be taken perpendicular to the face of the electronic message center at the distance determined by the total square footage of the electronic message center as set forth below:

For multi-tenant electronic message center signs:

Large Sign: 98 feet

Medium Sign: 73 feet for Symmetrical and Asymmetrical sign types; 84 feet for horizontal sign type

Small Sign: 49 feet for Symmetrical and Asymmetrical sign type; 57 feet for horizontal sign type

Other Sign Sizes: Measurement Distance = √ (Area of Sign (in sq. ft.) × 100)

b.

Electronic Message Center Illumination Limits. The difference between the off and solid-message measurements using the EMC Measurement Criteria shall not exceed 0.3 foot-candles on either side of the sign. If there is a difference in measurement of illumination levels on either side of the sign, the side of the sign facing residentially zoned properties shall take precedent.

c.

Dimming Capabilities. All electronic message centers shall be equipped with a sensor or other device that automatically determines the ambient illumination and programmed to automatically dim according to ambient light conditions, or that can be adjusted to comply with the 0.3 foot-candle measurements.

C.

Multi-tenant Electronic Message Centers. Multi-tenant electronic message centers are intended to provide an opportunity for unified, multi-tenant developments to advertise on-site businesses through uniform sign designs subject to the requirements set forth in this subsection C.

(Ord. 2023-O-14 §4; Ord. 2024-O-13 §48; Ord. 2024-O-18 §10)

A.

Generally. There are many forms of detached signs. This section sets out which forms of detached signs are allowed in each zoning district, and the size and height standards that apply to them.

B.

Required Setbacks. All detached signs shall be set back at least 10 feet from all property lines. This standard may be waived if:

1.

The sign is proposed to be affixed to an existing retaining wall, masonry fence, or stucco fence that is closer than 10 feet to the property line (but not across it); or

2.

The waiver would lower the elevation of the base of the sign by more than three feet and:

a.

The sign will be set back at least one foot from any sidewalk;

b.

The sign will not encroach on any utility easement;

c.

The sign will not obstruct a sight distance required by Section 12-11-208, Sight Triangle and Sight Distance Requirements; and

d.

There is at least five feet of landscaped parkway between the edge of pavement and the property line; or

D.

Exceptions and Special Provisions.

1.

Residential Model Homes. In addition to the signage that is permitted by Table 12-6-402A, Permissible Detached Sign Types, Agricultural and Residential Districts, and Table 12-6-402B, Permissible Detached Sign Types, Nonresidential and Mixed-Use Districts, one monument sign is permitted per model home within an approved subdivision; provided that the surface area of the sign does not exceed 16 square feet, and the height does not exceed five feet. Such signage shall not be required to meet minimum setback requirements of the zone district in which it is located with respect to minor streets that are internal to the subdivision, but shall not be placed in sight triangles or obstruct sight distances required by Section 12-11-208, Sight Triangle and Sight Distance Requirements.

2.

Each sign may be up to 16 feet in height, up to 150 square feet in sign area, and may contain up to 30 items of information. For the purposes of this regulation, a full service hospital (including a medical center) is a hospital that provides overnight and extended in-patient care and 24-hour emergency room services.

3.

Freeway Oriented Commercial Retail and Mixed Use Developments.

a.

The City Council finds that large retail developments that are adjacent to I-25 have unique needs for communicating their messages due to the high rate of speed of Interstate highway traffic, and the elevation of the Interstate compared to abutting properties. The regulations of subsection B.3.b., below apply to development that meets all of the following criteria:

i.

Unified commercial retail developments of more than 100,000 square feet of floor area, or mixed-used developments that contain more than 70,000 square feet of commercial retail floor area and more than 250,000 square feet of total floor area;

ii.

A minimum area of the parcel proposed for development of 10 acres; and

iii.

The parcel proposed for development directly abuts the I-25 right-of-way.

b.

Development that meets all of the criteria of subsection B.3.a., above, may display a monument sign that is subject to the following standards:

i.

Maximum sign height: 32 feet.

ii.

Alternative points of measurement: The point of measurement for sign height is either the centerline of I-25 or the top of the light rail line, whichever is higher.

iii.

Maximum sign area: 150 square feet.

iv.

Setbacks and location: The sign shall be located in the yard that abuts I-25, and shall be set back at least 10 feet from all property lines.

v.

Minimum spacing from other freeway oriented signs: 300 feet.

vi.

The sign must be compatible with surrounding architecture in general appearance and materials.

vii.

The sign shall also include landscaping in the form of shrubs, decorative grasses, perennials, or other ornamental materials around the base of the structure that are maintained by a subsurface irrigation system.

viii.

The sign permitted by this subsection is in addition to the signs that are permitted by Table 12-6-402B, Permissible Detached Sign Types, Nonresidential and Mixed-Use Districts.

4.

Off-Premises Signage for Large Commercial Retail and Mixed-Use Development.

a.

The City Council finds that large retail developments that are not located on property with frontage on a major arterial have unique needs for communicating their messages due to decreased visibility and the high volumes of traffic that seek the use. The regulations of subsection B.4.b., below, apply to development that meets all of the following criteria:

i.

Unified commercial retail developments of more than 100,000 square feet of floor area;

ii.

A minimum area of the parcel proposed for development of 10 acres; and

iii.

A location without frontage on a major arterial, but not more than ¾ mile distant from a major arterial.

b.

Development that meets all of the criteria of subsection B.4.a., above, may display up to two off-premises monument signs, provided that each sign meets all of the following criteria:

i.

The sign must be located within ¾ mile from the parcel proposed for development;

ii.

The sign must be located along a major arterial street;

iii.

The minimum distance between off-premises signs permitted by this Section is at least 300 feet;

iv.

The sign must be compatible with surrounding architecture in general appearance and materials;

v.

The sign shall also include landscaping in the form of shrubs, decorative grasses, perennials, or other ornamental materials around the base of the structure that are maintained by a subsurface irrigation system; and

vi.

The sign permitted by this subsection is in addition to the on-premises signs that are permitted by Table 12-6-402B, Permissible Detached Sign Types, Nonresidential and Mixed-Use Districts.

(Ord. 2021-O-13 §28; Ord. 2022-O-21 §5; Ord. 2023-O-14 §§5—8; Ord. 2024-O-13 §49; Ord. 2024-O-15 §§12—14)

A.

Generally. There are many forms of temporary signs. This section sets out which forms of temporary signs are allowed in each zoning district, and the size and height standards that apply to them. Sign types that are not listed in Table 12-6-501A, Permissible Freestanding Temporary Sign Types, Agricultural and Residential Zoning Districts, or Table 12-6-501B, Permissible Freestanding Temporary Sign Types, Nonresidential and Mixed-Use Zoning Districts, are not permitted as freestanding signs.

B.

Setbacks. All temporary signs shall be set back at least five feet from all property lines, except as provided in Section 12-6-502, Prevention of Visual Clutter in Principal Corridors. Temporary signs that are not visible from public rights-of-way or abutting property are not restricted by this Section.

C.

Exceptions and Special Provisions.

1.

Off Premise Directional Signs. The City Council finds that due to the configuration of streets and the patterns of traffic in the City of Centennial, there is a need to enhance wayfinding to emergency services and real estate developments. As such, temporary off-premises wayfinding signage is permitted for a period of not more than one year if it meets the criteria of Table 12-6-501A, Permissible Freestanding Temporary Sign Types, Agricultural and Residential Zoning Districts, or Table 12-6-501B, Permissible Freestanding Temporary Sign Types, Nonresidential and Mixed-Use Zoning Districts, and it is demonstrated that:

a.

The signs are located on private property with permission of the landowner;

b.

The signs are located along an arterial frontage;

c.

The signs are located in compliance with Section 12-6-502, Prevention of Visual Clutter in Principal Corridors; and

d.

The signs are separated by a distance of at least 300 feet.

(Ord. 2024-O-13 §50)

A.

Generally. The City Council finds that the proliferation of temporary signage along the principal corridors of the City causes visual clutter that is detrimental to the character of the community, and tends to be distracting to motorists. The City Council also finds that the application of this Section does not restrict the ample alternative ways that residents and business owners may communicate their messages.

B.

Corridor Setback Requirement.

1.

No temporary sign shall be placed within the right-of-way (as provided in Section 12-6-302, Prohibited Sign Locations), or within 30 feet of the edge of pavement (whichever creates a greater setback from the edge of pavement), along the following street corridors:

•

E. Arapahoe Road;

•

E. Briarwood Avenue;

•

E. Broncos Parkway;

•

E. County Line Road;

•

E. Dry Creek Road;

•

E. Easter Avenue (East of S. Havana Street);

•

E. Fremont Avenue (West of S. Jordan Road and east of S. Tucson Way);

•

E. Orchard Road;

•

E. Peakview Avenue;

•

E. Smoky Hill Road;

•

S. Broadway;

•

S. Buckley Road;

•

S. Colorado Boulevard;

•

S. Chambers Road;

•

S. Chester Street;

•

S. Clinton Street;

•

S. Dayton Street;

•

S. Parker Road;

•

S. Picadilly Street;

•

S. Peoria Street;

•

S. Potomac Street;

•

S. Quebec Street;

•

S. Reservoir Road;

•

S. Tower Road;

•

S. University Boulevard; and

•

S. Yosemite Street.

2.

The setback requirement of this Section shall not apply in the following circumstances:

a.

Where the front yard of any lot that is used or zoned for single-family residential purposes abuts any right-of-way identified in subsection (1) above.

b.

Where an intervening private fence, wall, or other structure clearly delineates the boundary of private property outside of the prescribed public right-of-way, in which case the required setback shall include only the area up to and including the outside surface of such private fence, wall, or other structure.

c.

To information signs posted on private property by a school, homeowner, or civic association, special district organized under Title 32 of the Colorado Revised Statutes, or other public entity for the sole purpose of advertising events and meetings to constituents, provided such signage, on its face, is clearly marked with date of posting, name of entity posting sign, and statement that sign is posted with permission of property owner and provided such signage is removed within forty-eight (48) hours of the conclusion of the event or meeting.

(Ord. 2021-O-13 §29)

A.

Generally. Attached and detached temporary signs are permitted subject to the standards of this Section, for a duration as set out in Section 12-6-504, Duration of Temporary Signs.

B.

Banners. Banners are permitted in the CG, AC, UC, EC, BP, I, ED, and OSR districts, provided that:

1.

There is only one banner per tenant per principal building;

2.

The banner is attached to the principal building or accessory structure, and complies with the standards of Section 12-6-302, Prohibited Sign Locations; and

3.

The sign area on the banner is not larger than the sign area allowed for a wall sign on the building.

; Ord. 2024-O-18 §11

C.

Sock Signs and Temporary Wall Signs. Sock signs and temporary wall signs are permitted in CG, AC, UC, EC, BP, I, ED and OSR districts, and may be installed upon issuance of a building permit. Such signs shall have a sign area that is not more than 15 percent larger than that which is permitted for the permanent sign for which the permit application was filed.

D.

Window Signs. Temporary window signs are allowed in all locations where permanent window signs are allowed, provided that the transparency standards of Section 12-6-401, Attached Signs, are met.

(Ord. 2021-O-13 §31; Ord. 2024-O-13 §51)

A.

Generally. The purpose of temporary signs is to display messages for a temporary duration. Temporary signs shall not be used as a subterfuge to circumvent the regulations that apply to permanent signs or to add permanent signage to a parcel proposed for development in addition to that which is permitted by Division 6-4, Permanent Signs.

B.

Duration of Display.

1.

In general, temporary signs shall be removed as of the earlier of the date that:

a.

A commercial message is obsolete and has become misleading or off-premises (e.g., a "for lease" or "for sale" sign in front of a building that is fully occupied);

b.

The sign falls into disrepair (see Section 12-6-306, Sign Maintenance); or

c.

The number of days set out in Table 12-6-504A, Duration of Detached Temporary Signs, or Table 12-6-504B, Duration of Attached Temporary Signs, expires.

2.

For signs posted in accordance with Section 12-14-311, Public Notice, the sign shall be removed within five days after the date of the noticed hearing or event.

C.

Administrative Interpretations. The City Council finds that materials technology is a rapidly evolving field of study, and that materials for signage that are not listed in Table 12-6-504A, Duration of Detached Temporary Signs or Table 12-6-504B, Duration of Attached Temporary Signs, may be introduced into the market. When an unlisted material is proposed, the Director shall determine to which class of materials the new material is comparable, based on the new material's appearance, durability, and colorfastness. No sign displays shall be longer in duration than the longest permitted display in Table 12-6-504A, Duration of Detached Temporary Signs or Table 12-6-504B, Duration of Attached Temporary Signs regardless of the material.

(Ord. 2021-O-13 §32; Ord. 2024-O-13 §§52, 53; Ord. 2024-O-18 §§12, 13)

A.

Generally.

1.

Purpose. The requirements of Division 6-1 to Division 6-5 ensure that signs that meet certain minimum standards that are consistent with the character and quality of development in Centennial may be quickly approved and displayed. For some developments, alternative standards may contribute to the aesthetic qualities of the development. Approval of a Sign Design Program pursuant to the standards of this Division allows for unified presentation of signage throughout a Parcel Proposed for Development, flexibility to provide for unique environments, and pre-approval of designs and design elements to make subsequent applications for sign permits more efficient.

2.

Sign Design Program Flexibility. Signage which is proposed as part of a Sign Design Program may deviate from the standards found in Division 6-1 to Division 6-5 in terms of the types and numbers of signs allowed, the maximum sign area, the maximum signable area ratio, and materials and illumination standards (including electronic message centers), subject to compliance with a Sign Design Program that is approved according to the approval criteria set out in this Section. The Director shall review all Attached, Detached, and Temporary Sign types for the Parcel Proposed for Development, to determine the degree of compliance with this Article.

B.

Sign Design Program Requirements.

1.

An application for a Sign Design Program may be initiated by property owner(s) with a majority ownership interest within the Parcel Proposed for Development, or by the City of Centennial. For purposes of this Section 12-6-601, majority ownership interest shall mean the owners of at least 50% of the total land area which constitutes the Parcel Proposed for Development. Prior to application submittal, an Applicant submitting a Sign Design Program shall mail or otherwise deliver a courtesy notice to all property owners and tenants impacted by the proposed Sign Design Program so that the notice is given least three (3) days prior to application submittal.

2.

A Sign Design Program shall set forth a master plan for all signage for an entire Parcel Proposed for Development. For example, shopping center Sign Design Programs shall include all tenants and lots; and office or industrial parks shall include all types of signs for wayfinding and tenants or uses within the development. Parcels Proposed for Development comprising a single tenant and single parcel shall not be eligible for a Sign Design Program.

3.

Attached and Detached Signs within a Sign Design Program shall be architecturally integrated into or complimentary to the design of the buildings and character of the site, and shall use similar and coordinated design features, materials, and colors. The Sign Design Program shall establish an integrated architectural vocabulary and cohesive theme for the Parcel Proposed for Development.

4.

The Sign Design Program's maximum permitted sign area shall be based on the following formula:

a.

Attached Signage. The maximum area permitted for Attached Signs shall not exceed six (6%) percent of the building façade to which the sign is to be attached.

b.

Detached Signage. The maximum total permitted area of all Detached Signs shall not exceed one-hundred ten (110%) percent of the total sign area that would otherwise be permitted by Section 12-6-402, Detached Signs.

c.

The Applicant shall develop a comparison model of Attached and Detached Signage for the Parcel Proposed for Development to determine the maximum Attached and Detached Signage allowed for the Parcel Proposed for Development in comparison to what is allowable in the underlying zone district.

5.

The height, area, number and location of signs permitted through the Sign Design Program shall include the following considerations:

a.

The overall size of the Parcel Proposed for Development and the scale of the use or uses located or anticipated to be located there (larger land areas and scales of use tend to favor larger signs and/or more signs);

b.

Relationship between the building setback and sign location. Additional signage may be appropriate for buildings with less visibility, particularly where buffering is providing an aesthetic and/or environmental benefit to the City;

c.

Frontage (larger frontages may justify more or larger signs, particularly if the size of the frontage tends to prevent sign clutter from multiple adjacent parcels);

d.

Access and visibility to the site;

e.

Intended traffic circulation pattern and the need for wayfinding;

f.

Hierarchy of signage; and

g.

Relationship between the site and adjacent uses.

6.

Elimination of Nonconforming Signs. All existing Detached and Attached Signs shall be brought into conformance with the standards of the approved Sign Design Program. The Sign Design Program shall establish a reasonable timeline for bringing existing non-conforming signs into compliance with the Sign Design Program.

7.

Prohibited Signs and Sign Elements. Prohibited signs and sign elements are not eligible for inclusion in a Sign Design Program unless specifically indicated in this Article.

8.

Modification of Sign Setbacks. Setbacks for detached signs may deviate from the requirements of this Article if it is demonstrated that there is no negative impact on public safety or utility easements, and all other requirements for approval of a Sign Design Program are met.

9.

Sign Permit Review and Approval. All Sign Design Programs shall include a provision that sets forth that all sign permits submitted to the City require a property owner or property owner representative (such as a landlord or management company) to review proposed signs against the Sign Design Program prior to a sign permit being submitted for review to the City. If the City requests any modification to the owner or property owner representative sign permit submittal, the owner or property owner representative shall have the opportunity to review and approve any of the modifications prior to the City's issuance of a sign permit.

10.

Lighting. Lighting standards for signs shall not deviate from the standards of this Article, unless the signs:

a.

Are not visible from outside of the Parcel Proposed for Development;

b.

Do not create Light Pollution under normal conditions; and

c.

Do not shine into windows of residential units located within or adjacent to the Parcel Proposed for Development.

C.

Sign Design Program Application. The Director shall promulgate a standard application form for a Sign Design Program which application shall include, at a minimum, the following:

1.

A letter of intent that addresses the overall vision of the Sign Design Program.

2.

Sworn proof of ownership and a notarized letter of authorization from property owner(s) constituting the majority ownership interest within the Parcel Proposed for Development permitting a representative to process the application.

G.

Amendments to a Sign Design Program. Amendments to Sign Design Programs shall follow the procedures of this Section and meet the approval criteria set forth in Section 12-6-601(D). The Director may waive or modify application requirements upon a finding that the requirements do not relate to the amendment of the Sign Design Program for which the waiver is requested.

H.

Repeal of a Sign Design Program. A repeal of a Sign Design Program may be initiated by property owner(s) with a majority ownership interest within the Parcel Proposed for Development, or by the City of Centennial. An application to request the repeal of a Sign Design Program shall be accompanied by a letter that provides contact information, the applicable Sign Design Program, the reason for requesting the repeal of the Sign Design Program, and any evidence or documentation that supports the request. In considering the repeal, the Director shall make a finding that the Sign Design Program is no longer appropriate based on changes to the use of the Parcel Proposed for Development, changes to the allowable signage in the underlying zone district, or a rezoning of the Parcel Proposed for Development. Following repeal of a Sign Design Program, the underlying zone district's sign standards shall govern. Signs that remain on the Parcel Proposed for Development after the repeal of a Sign Design Program shall be considered non-conforming signs if they do not meet the standards of the underlying zone district.

(Ord. 2024-O-07 §2)

Editor's note— Ord. 2024-O-07 §2, adopted June 11, 2024, repealed § 12-6-602, which pertained to flexibility criteria and derived from the City of Centennial Zoning and Subdivision Regulations.

A.

Generally. It is the purpose of this Division to define practical and effective measures by which the obtrusive aspects of excessive and/or careless outdoor light usage can be minimized, while preserving safety, security, and nighttime use and enjoyment of property. These measures will help to curtail the degradation of the nighttime visual environment by encouraging lighting practices that direct appropriate amounts of light where needed, decrease the waste of energy associated with exterior lighting, help reduce glare associated with the use of poorly shielded or inappropriately aimed lighting fixtures, and reduce the contribution to light pollution from exterior lighting.

B.

Exterior Lighting Standards. The exterior lighting standards designate illuminance, uniformity and spill light criteria for properties based upon the Lighting Zone (LZ) in which the property is located. In addition to criteria based upon Lighting Zone, the exterior lighting standards include restrictions on connected load, lamps, lighting equipment, mounting conditions and hours of operation, as well as submittal requirements to demonstrate compliance. An alternate submittal and approval process is provided for a lighting submittal which meets the intent of these restrictions but which may be in violation of specific regulations in this Division.

A.

Generally. The exterior lighting standards are applicable to all land uses except single-family detached residential dwelling units on individual lots not governed by a site plan (subdivision development lighting for streets and residential developments are not exempt). For single-family detached residential dwelling units on individual lots not governed by a site plan, all exterior lighting, including but not limited to floodlights, spotlights, and security lighting, shall be fully shielded to prevent glare and light trespass. Additionally, floodlights and similar directional lighting shall be externally shielded, and all lighting shall comply with the maximum foot-candle limits set forth in Table 12-6-705(C).

B.

Existing Lighting Systems. Existing lighting legally installed and operational as of September 17, 2011 shall be permitted to remain in operation until any of the thresholds for compliance established in this Section are met. Additionally, lighting designs previously reviewed and approved by the City but not yet constructed, through either an unexpired Administrative Site Plan, Subdivision Development Plan, or Final Development Plan or a vested property right through a site specific development plan, shall be exempt from the exterior lighting standards provided that such systems are constructed in accordance with the previously approved plan.

C.

Threshold for Compliance. Compliance with the requirements of this Division shall apply in any of the following scenarios:

1.

New development or redevelopment pursuant to Section 12-12-402, Sliding Scale Compliance Requirements; or

Because of the unique requirements for nighttime visibility and their limited hours of operation, ball diamonds, playing fields, tennis and pickleball courts, and other similar outdoor recreation uses and recreational facilities, are exempted from conformance with the requirements of this Division, except:

1.

Lighting for areas where the outdoor recreation is conducted shall not exceed 125 percent of the values cited in the current Illuminating Engineering Society of North America (IESNA) recommended practice for that sport, level of play and class of facility approved by the City;

2.

The maximum permitted mounting height is 80 feet;

3.

The maximum permitted illumination at the property line is 2 footcandles; and

4.

Limits on hours of illumination require that exterior lighting shall be extinguished no later than 11:00 p.m. unless a different requirement is established for a particular use or activity.

F.

Exempted Lighting Systems. The following lighting systems are exempted from conformance with the requirements of this Division:

1.

Lighting used to control and regulate the flow of pedestrian and motor vehicle movement on public rights-of-way;

2.

Temporary lighting for construction, provided that such lighting is of a temporary nature and is discontinued daily immediately upon completion of the construction work for the day. Where safety is a concern, this lighting may be allowed to remain in operation after daily construction operations are complete through a written request to the Director;

3.

Lighting used as decoration for any national, state, local or religious holiday provided that the lighting is of a temporary nature and energized for no more than 90 nights in any contiguous 12 month period;

For driveways between parking areas and roadways where the roadway is permitted a greater illuminance than the parking area, the maximum illuminance for the driveway shall be allowed to equal the roadway's maximum illuminance. Further, this driveway area shall be considered separate from the parking area for the purposes of calculating the uniformity ratio.

D.

Spill Light Limits. Lighting Zones designate how much spill light is permitted onto a property from an adjacent property. The relevant Lighting Zone is the one for the property receiving the light from an adjacent property. Spill light may be measured by either horizontal measurements at grade or by vertical measurements at the property line up to the height of the highest window on the property receiving the spill light. Where vertical measurements at the property line are impractical, measurements at windows may be substituted.

E.

Exceptions to Spill Light Limits. All exterior lighting shall comply with the spill light limits set in Table 12-6-705C, Spill Light-Maximum Limits, except:

1.

Spill light onto public rights-of-way at entries to a property may be the greater of one third of the maximum allowed illuminance for the parking area on the property or one third of the maximum allowed illuminance for the roadway; and

2.

When the maximum light spill at a boundary between two properties exceeds the limits specified in Table 12-6-705C, Spill Light-Maximum Limits, due to the contributions from existing lighting located on either the receiving property or another adjacent property not subject to the proposed development or redevelopment.
