ARTICLE 5
MEASUREMENTS AND COMPUTATION

Section 21-5-1. Determining Sign Area.

(a)

Wall Signs.

(1)

For a wall sign which is framed, outlined, painted or otherwise prepared and intended to provide a background for a sign display, the area shall include the entire portion within such background or frame.

(2)

For a wall sign without a distinguishable frame or outline, the area shall be determined by the following:

(A)

The area of the sign shall encompass a regular geometric shape (rectangle, circle, trapezoid, triangle, etc.), or a combination of regular geometric shapes, which form, or approximate, the perimeter of all elements in the display, the frame, and any applied background that is not part of the architecture of the building.

(B)

When multiple elements are organized to form a single sign, but are separated by open space, the sign area and dimensions shall be calculated by determining the geometric form, or combination of forms, which comprises all of the display area, including the space between different elements.

(C)

Minor appendages to a particular regular shape, as determined by the Director, shall not be included in the total area of a sign.

(b)

Freestanding Signs.

(1)

The sign area shall include the frame, if any, but shall not include:

(A)

A pole or other structural support unless such pole or structural support is internally illuminated or otherwise designed to constitute a display device, or a part of a display device.

(B)

Architectural features that are part of a freestanding structure, and not an integral part of the sign, and which may consist of landscaping, building or structural forms complementing the site in general as determined by the Director, shall not be included in the total area of a sign.

(2)

Multi-faced signs are measured as a total of all sign faces. However, when two (2) identical sign faces are placed back to back so that both faces cannot be viewed from any point at the same time and are part of the same sign structure, the sign area shall be computed as the measurement of one (1) of the two (2) faces. When the sign has more than two (2) display surfaces, the area of the sign shall be the total area of largest display surfaces that are visible from any single direction.

(c)

Disputes. If an applicant does not agree with the determination of sign area, the applicant can submit a formal application to the Board of Adjustment in accordance with Section 11-42-5 of the City of Northglenn Zoning Ordinance.

Section 21-5-2. Determining Sign Height.

(a)

The height of a freestanding sign shall be measured from the base of the sign or supportive structure at its point of attachment to the ground, to the highest point of the sign. A freestanding sign on an elevated base of any kind, including a graded earth mound, shall be measured from the grade of the nearest pavement or top of any pavement curb.

(b)

Clearance for freestanding and projecting signs shall be measured as the smallest vertical distance between finished grade and the lowest point of the sign including any framework or other embellishments.

Section 21-5-3. Illumination.

(a)

Lighting for signs shall not create a hazardous glare for pedestrians or vehicles either in a public street or on any private premises.

(b)

The light source, whether direct, indirect, or internal, shall be shielded from view. This requirement is not intended to preclude the use of diffused exposed neon or electronic message centers (EMC).

(c)

Illumination for directly or indirectly illuminated signs shall utilize focused light fixtures that do not allow light or glare to shine above the horizontal plane of the top of the sign or onto any public right-of-way or adjoining property.

(d)

Each internally illuminated sign (including EMCs) shall be designed so that illumination does not exceed five hundred (500) nits (candelas per square meter).

(e)

Each directly or indirectly lit sign shall be designed so that illumination does not exceed one hundred (100) luxes (10 footcandles) measured at a distance of ten (10) feet from the sign.

Section 21-5-4. Building Façades.

(a)

The building façade shall include the building walls that face a public street or a parking lot which serves the uses therein.

(b)

The area of any building façade shall be defined as the square footage of all wall areas parallel, or nearly parallel, to a street frontage, excluding any such wall area determined by the Director as clearly unrelated to the facade criteria.

(c)

Buildings with two (2) or more façades. The square footage of the wall and allowable sign area shall be calculated separately for each such building façade.

(d)

Multiple-tenant Building. The sign area for a multiple tenant unit shall be determined by measuring the square footage of that tenant unit's building facade.

Section 21-5-5. Vision Triangles.

(a)

A vision triangle free of sign obstructions is required where a driveway intersects a public right-of-way or where property abuts the intersection of two (2) public rights-of-way. Unobstructed sight distance shall be provided at all times within the vision triangle area of the property adjacent to the intersection in order to ensure that safe and adequate sight distance is provided for the public use of the right-of-way.

(b)

Planning and Development staff will determine the classification of all adjacent roadways used in calculating the required unobstructed sight distance at all intersections.

(c)

Table 1 below depicts the required linear flow line distance for each leg of a vision triangle in correspondence with the listed street classification system.
