Part IV: Employment Zoning Districts

Article 9. Innovation Mixed-Use Zoning District: IMU

9.1 PURPOSE

The IMU Innovation Mixed-Use Zoning District is intended to accommodate those areas that have typically developed as industrial areas, but are transitioning from an exclusively industrial orientation to a broader mix of light industrial, artisan industrial, commercial, and moderate density residential uses, within a more walkable environment. As such, IMU Zoning District standards encourage and accommodate the adaptive reuse of existing structures.

9.2 USES

Article 15 lists permitted, temporary, and accessory uses for the Innovation Mixed-Use Zoning District. Use definitions are found in Article 15. Prescribed conditions applicable to certain principal uses, temporary uses, and accessory uses are also found in Article 15.

9.3 DIMENSIONAL AND DESIGN STANDARDS

The tables below include the dimensional and design standards for the Innovation Mixed-Use Zoning District. Standards within the tables below may contain specific regulations organized by frontage type (Section 3.5). In the tables below, where a cell contains a standard or a “✔” the standard is applicable. Where a cell is blank and shaded, the standard does not apply.

A. General

1. Within the IMU Zoning District, the following shall apply to multi-family attached residential developments:

a. If a minimum 25’ Class B landscape yard, measured from the future right-of-way line, abuts and runs parallel to an arterial street, the portion of the arterial street abutting this landscape yard shall not be considered a frontage for the standards of this article. The portion of the arterial street abutting this landscape yard shall still be considered a frontage for the standards of the remainder of this Ordinance. No parking lots shall be located between these landscape yards and permitted uses.

2. For sites with three or more frontages, see Section 3.6 for alternative standards for ground floor activation, required prominent entrances, prominent entry design, and ground floor transparency.

B. Building Siting
Building siting standards govern the placement of buildings on lots and are intended to ensure that development maintains compatibility with its surrounding context and the intent of the applicable zoning district.

¹ On local and collector streets, measured from the curb location for Office/Commercial Wide Local Street Cross Section in CLDSM or the existing back of curb, whichever is farthest from the centerline. If SSI standards require the installation of curb, the relocation of the back of curb, or the back of curb is voluntarily relocated, that shall be considered the existing back of curb location.

² In no case shall any building entry be located closer than six feet to an existing or proposed off-street public path or shared use path.

³ For the transit station, off-street public path, public park frontage, shall be measured from a property line or right-of-way line. If there is an easement in place for any frontage, then the measurement shall be taken from such easement. For any frontage abutting a reservation for a future frontage, the frontage setback line shall be measured from the edge of the reservation area.

⁴ When an existing Charlotte Water easement, other utility easement, or overhead utility clearance requirement conflicts with the build-to zone requirement, a build-to line shall be established at the edge of the easement or edge of the overhead utility clearance requirement closest to the build-to zone. A build-to zone shall not be required along frontages which abut a man-made or natural physical feature 35 feet in width or greater such as, but not limited to, a railroad line, rapid transit line, gas pipeline, SWIM buffer, or a buffer related to post-construction stormwater requirements. This does not include any stormwater control measure as required by this Ordinance.

⁵ Where a lot has more than two frontages that require a build-to zone, the build-to zone shall be increased by 100% for those frontages that exceed two. Such an increase should be applied to those frontages that are lowest in the established hierarchy of frontages (Section 3.5.D).

C. Building Height

Image from document

Building height standards govern the minimum and maximum heights of buildings as applicable and are intended to provide flexibility while maintaining appropriate transitions to adjacent areas.

		IMU
A	Minimum Building Height (feet)¹	24
B	Maximum Building Height (feet)^2,3	80
C	Maximum Height with Bonus (feet) (Section 16.3)^2,3	120

1 Lots of one-half acre in area or less are exempt from any applicable minimum building height requirements. Buildings of 2,000sf or less of gross floor area are exempt from any applicable minimum building height requirements.

2 The height and location of structures may be restricted by the limitations set forth in the Code of Federal Regulations (CFR) Title 14 Part 77: Safe, Efficient Use, and Preservation of the Navigable Airspace. A notice of proposed construction FAA Form 7460-1 must be filed with the FAA for construction or alteration that impacts any of the imaginary surfaces as defined in 14 CFR Part 77 or is more than 200 feet in height above the ground at its site at least 45 days prior to construction. The Aviation Department Planning Division may serve as a point of contact for information regarding building notification requirements and obstruction evaluation

3 The maximum building height of any structure within 200 feet from the lot line of residential uses or vacant land in a Neighborhood 1 Place Type is limited as follows: Portions of a structure within the first 100 feet are limited to a maximum height of 50 feet. Portions of a structure located between 100 and 200 feet are limited to a maximum height of 65 feet. Beyond 200 feet, the building height is limited by the maximum height of the zoning district. Building heights for all portions of a structure shall be measured from the average grade established for the whole building. This limitation does not apply to public parks of three acres or greater within a Neighborhood 1 Place Type, nor to an area of two or fewer parcels totaling no more than three acres within a Neighborhood 1 Place Type.

D. Building Articulation

Building articulation standards govern the dimensions of building facade elements and entry features and are intended to facilitate the enhancement of a pedestrian-oriented environment.

¹ Where a minimum building length as a percentage of lot width applies to multiple frontages, the highest frontage classification in the hierarchy (per Section 3.5.D) shall meet the established standard. In the case of a lot with two frontages, the second frontage shall only meet a standard of 40%. If there are more than two frottages subject to the standard, there is no minimum requirement for any frontage beyond the two highest frontages in the hierarchy. This requirement does not apply to Parkway or Limited Access frontages.

² Maximum building length along a frontage does not apply to any frontage located along a Limited Access road. If any applicable minimum building length exceeds a maximum building length requirement, the maximum building length shall control.

³ To achieve maximum building length with additional design elements, the following is required:

A. Where a building abuts two parallel frontages with pedestrian facilities, or one frontage with pedestrian facilities and a parking lot, public park or other publicly owned open space on the side of the building opposite the frontage, a pedestrian passage is required. Such passage shall meet the following criteria:

1.General Requirements

a. Passages shall be designed to accommodate pedestrians. Vehicular access and circulation shall not be allowed as a component of a passage.

b. Passages shall be a minimum of 30 feet in width and 20 feet in height and shall be located within the middle third of the building, measured along the frontage.

c. Passages shall be designed to maintain views from one end through to the other.
d. Inclusion of decorative elements such as lighting installations or public art within passages is encouraged.

e. Passages shall align with the street grid or other points of access to sidewalks, public paths, parking lots, public parks or other publicly owned open space where feasible.

f. For the purposes of any build-to zone requirement, a building passage is considered part of the building façade that meets such requirement.

2.Passages in nonresidential and mixed-use buildings.

a. Ground floor uses shall be oriented toward the passage, including public entrances.

b. Ground floor façades facing into building passages in nonresidential and mixed-use buildings shall maintain a minimum transparency of 35% of the wall area of the passage.

3.Passages in residential buildings.

a. Passages in residential buildings may be closed off to the public with gates and/or fencing but shall be of open design to allow for a clear view through the passage.

b. Passages in residential buildings shall be designed with elements for use by residents, such as seating areas.

c. Ground floor façades facing into building passages in residential buildings shall maintain a minimum transparency of 25% of the wall area of the passage

B. Where a building does not abut two parallel frontages with pedestrian facilities, a break in the building massing is required as follows:

1. Building mass shall be recessed a minimum of 20 feet in depth for no less than 30 linear feet along the façade. Such recess shall extend the full height of the building, and shall meet the following criteria:

a. The recess shall be located within the middle third of the building, measured along the frontage.

b. For nonresidential and mixed-use buildings, ground floor uses shall be oriented toward the recessed area, including public entrances.

c. The recessed area is subject to all transparency requirements.

d. The recessed area shall be designed as public or common space including amenities such as seating areas, landscaping, lighting, decorative elements, and public art.

⁴Does not apply to multi-family attached units when on sublots.

⁵The ground floor of residential developments is still considered residential when leasing or management offices and/or tenant facilities, such as gyms and community/party rooms associated with the development are located on the ground floor.

⁶ Applies only if non-convertible residential; for convertible residential, nonresidential standard applies.

⁷ At least 70% of the total ground floor for nonresidential uses and 30% for residential uses, measured as a percentage of the interior space, shall meet the minimum ground floor height requirement.

⁸ Minimum ground floor heights can be reduced by the Zoning Administrator if there are site constraints that would cause practical difficulty.

⁹ On a site bounded by three or more street frontages, public open space that abuts a street frontage shall be counted as meeting building length for the purpose of calculating Minimum Building Length as a Percentage of Lot Width Along Frontage, subject to the following standards:

A. This provision shall only be applied to a single street frontage.

B. The abutting public open space shall comply with any applicable public open space standards of Table 16-2: Design of Open Space.
C. The abutting public open space is no more than an average of 24 inches above or below grade of the adjacent sidewalk.
D. The abutting public open space is a minimum of 50 feet in depth measured from the future right-of-way line.
E. If no building abuts the public open space, or no building is located along the subject frontage, the established setback shall be determined as the terminus of any required build-to zone along the subject frontage.
F. Any provided off-street parking shall be located behind this determined established setback.

¹⁰ Required landscape yards are excluded from the lot width dimension for the purposes of calculating Minimum Building Length as a Percentage of Lot Width Along Frontage.

E. Transparency
Transparency standards govern the required amount of ground floor and upper floor transparency and are intended to facilitate the enhancement of a pedestrian-oriented environment. These standards do not apply to multi-family attached development when units are on sublots.
