MIXED USE REGIONAL (MUR) DISTRICTS

(A) Process purpose and intent. The purpose of this section is to provide adequate review of applications for rezoning and/or development within the Innovation Districts. These procedures are intended to create an efficient and predictable review process for projects within the Economic Advancement Zone. The timing for reviews and approvals ensure that the EAZ is competitive with research and technology parks in other jurisdictions. Properties within the ID-5 District shall comply with procedures as provided for in § 153.051.

(1) Compatibility. It is the intent to ensure that development projects are completed in a manner generally harmonious with surrounding properties and without the endangerment of the health, safety, and general welfare of existing, prospective, or future owners, users, surrounding and adjoining properties, and the public.

(2) Coordination. These regulations and procedures are intended to ensure that development has adequate and efficient provision of facilities and/or infrastructure, land, rights-of-way, and easements, so as not to burden the fiscal resources of the city. These provisions include the construction of buildings and utilities, streets and sidewalks, landscaping, recreational open spaces, and other provisions meeting the standards of the city and the Community Plan, as required for the public good.

(B) Process summary. The following table provides an overview of the review procedures and requirements used in this section that apply to the Innovation Districts.

MIXED USE REGIONAL (MUR) DISTRICTS

§ 153.045 PURPOSE AND INTENT.

(A) Purpose. The Mixed Use Regional Districts are intended to implement the vision set forth in the Dublin Corporate Area Plan, which promotes a vision of a walkable, mixed use district that is comprised of high quality employment facilities, integrated with or adjacent to complementary retail and commercial uses as well as supporting residential and recreational uses, and pedestrian amenities. The Mixed Use Regional District standards are intended to ensure development is compatible with the surrounding character and uses.

(B) Applicability. Any development proposed to occur on land designated as Mixed Use Regional (MUR)-1, MUR-2, MUR-3, and MUR-4 shall be required to meet the requirements of the MUR Districts as specified herein.

(C) Conflicts. If the regulations within this section conflict in any manner with the City of Dublin Codified Ordinances, the provisions of the districts shall prevail. All matters not covered by the districts and their requirements shall be regulated by the requirements and standards contained in Chapter 153 of the Codified Ordinances.

(D) Relationship to Design Guidelines. In addition to the regulations contained within this section, new development within the MUR Zoning Districts shall comply with the Mixed Use Regional (MUR) Design Guidelines. The guidelines supplement the regulations contained within the Code and will guide the Planning and Zoning Commission in determining requests for approvals. While the Guidelines are not zoning regulations, they are critical to interpreting the intent of these regulations and should be used in unison with them. The Guidelines provide additional detail and explanation of the regulations and provide important guidance in applying the regulations. Applicants should consult the Design Guidelines prior to filing an application, and throughout the approval process.

(E) Intent. The titles of each zoning district reflect the general location of each district within the overall mixed use regional area as depicted in the Dublin Corporate Area Plan. The following further describes the intent of each of the Mixed Use Regional (MUR) Districts.

(1) MUR-1: Metro/Blazer District.

(2) MUR-2: Tuttle/Rings District.

(3) MUR-3: Emerald District.

(4) MUR-4: Llewellyn Farms Office District. The Llewellyn Farms Office District is different in character from the other MUR districts due to its proximity to existing residential neighborhoods. The permitted uses and development standards are sensitive to this and intend to provide a cohesive transition between residential and non-residential development focusing on lower density and intensity to ensure compatibility with the existing residential character.

(Ord. 86-21, passed 12-6-21)

§ 153.046 USES.

(A) Intent. This section establishes the desired uses for land and buildings in each of the MUR Districts. This is achieved through the variety of permitted, conditional, accessory, and temporary uses allowed in each district. In some cases, building location requirements and size limitations to establish the desired development character apply.

(B) General provisions.

(1) Permitted and conditional uses in each of the MUR Districts, shown in Table 1, may be restricted by location, size, period of operation, or other use-specific standards as designated herein.

(2) Explanation of terms.

(a) Listed uses are defined in § 153.002: Definitions.

(b) A “P” in a cell indicates a use that is permitted by right in that zoning district, subject to compliance with any use specific standards referenced in Table 1 and the applicable provisions herein.

(c) A “C” in a cell indicates a use that is allowed in that zoning district only upon approval of a conditional use as described in § 153.236 and compliance with any use specific standards referenced in Table 1 and the applicable provisions herein.

(d) An “S” in a cell indicates a use that is allowed in that zoning district only if limited in size, subject to compliance with any use specific standards referenced in Table 1 and the applicable provisions herein.

(e) A “T” in a cell indicates a use that is allowed in that zoning district for a limited period of time pursuant to a permit from the city, subject to compliance with any use specific standards referenced in Table 1 and the applicable provisions herein.

(e) An existing use in operation as of the effective date of this subchapter may be extended throughout any existing buildings or parts of a building that were clearly arranged or designed for that use at the time of adoption of this amendment, but the use shall not be extended to occupy any land outside the existing building except as permitted by this section.

(f) Expansion of existing buildings.

1. An existing building, including accessory structures and parking areas, may be enlarged, increased, or extended to occupy a greater area of the lot on which it is located subject to the applicable approval procedure set forth in § 153.048.

2. An expansion of an existing building, structure, or parking area that does not conform to the MUR dimensional standards may be permitted only after a finding by the required reviewing body that the expansion meets all of the following standards:

A. The expansion does not have a substantial detrimental effect on, or materially impair the use and enjoyment of, adjacent uses or lots, and does not limit the ability for adjacent lots to develop in accordance with this chapter;

B. The area in which the existing building, structure, or parking lot is being expanded complies with all other regulations applicable to the area affected by the proposed expansion, unless specifically exempted by the required reviewing body; and

C. The expansion complies with any reasonable conditions imposed by the required reviewing body that are necessary to ensure that the proposed expansion will not create impacts detrimental to adjacent properties or the surrounding community.

(5) Similar use determination.

(a) When a proposed land use is not explicitly listed in Table 1, the Director shall determine whether it is reasonably included in the definition of a listed use, or that the proposed use meets the following criteria to the extent that it should be treated as a permitted or conditional use in the district.

1. The use is not specifically listed in any of the MUR Districts.

2. The use is generally consistent with the intent of the MUR Districts and this chapter.

3. The use will not materially impair the present or potential use of other properties within the same district or bordering districts.

4. The use has no greater potential impact on surrounding properties than those listed in the district in terms of aesthetics, traffic generation, noise, potential nuisances, and other impacts related to health, safety, and welfare.

5. The use will not adversely affect the relevant elements of the Community Plan, the MUR Design Guidelines, and any other relevant plans or documents.

(b) The Director’s written determination shall be provided to the applicant and may be appealed to the Board of Zoning Appeals.

(6) Principal uses. Any property is permitted any combination of principal uses in accordance with the requirements of this section and other applicable provisions of this Code.

(7) Accessory uses.

(a) Accessory uses are permitted only in connection with a permitted or approved conditional use on the same property and must be clearly subordinate and incidental to that use.

(b) Temporary uses are governed by time limits as provided by this Code.

(c) Exemptions. The requirement to screen roof-mounted or ground-mounted equipment shall not apply if the only feasible location for screening would impede the functioning of solar, wind, or geothermal energy equipment or systems.

(E) Architectural requirements.

(1) Applicability. Architectural requirements as specified in this section shall apply to new construction. New construction is also subject to the MUR Design Guidelines as applicable. Design of additions to structures existing as of the date of this amendment may coordinate with the architecture of the existing structure, but to the extent possible shall meet the requirements of this section.

(2) Windows. Building walls shall incorporate windows or glass openings to effectively avoid blank and undifferentiated elevations, while balancing the needs of internal spaces and operations. Windows and glass openings on second stories or above that abut and face towards a residential zoning district or use are subject to the review and approval of the Planning and Zoning Commission. Applicants shall strategically locate second story and higher windows that face a residential use to avoid direct lines of sight to such uses. Landscaping may be used to buffer direct lines of sight.

(3) Roofs.

(a) Pitched and flat roof types are permitted, unless specified.

(b) Pitched roof shall not be sloped less than a 6:12 (rise:run) or more than 12:12, unless otherwise approved by the required reviewing body.

6. Synthetics. Synthetic siding materials such as fiber cement siding and EIFS may be acceptable if carefully integrated into the building’s design and detailed with a high level of shadow lines and reveals. EIFS is not permitted on the ground story.

7. Other primary building materials may be approved by the Planning and Zoning Commission if demonstrated to be of similar quality to the permitted primary materials.

(b) Secondary materials.

1. Any primary material listed above may be considered as a secondary material.

2. Gypsum fiber reinforced concrete (GFRC), wood siding, fiber cement siding and Exterior Insulation and Finishing Systems (EIFS) may be used for trim, detailing, and architectural features.

3. Other secondary building materials may be approved if demonstrated to be of similar quality to the permitted secondary materials.

(5) Accessory structures. Attached or detached accessory structures shall be constructed similar in design, style, quality, and appearance with identical materials as the principal structure.

(F) Landscaping and tree preservation.

(1) General.

(a) The provisions of §§ 153.130 through 153.149 shall apply to the MUR Zoning Districts, unless specifically exempted, modified, or waived by the Planning and Zoning Commission.

(b) Site landscaping shall comply with the general character and design components as prescribed in the Dublin Corporate Area Plan and the MUR Design Guidelines.

(2) Perimeter landscape buffer. The following landscape regulations apply to properties contained within the MUR Zoning Districts:

(a) Perimeter landscape buffer is required when a non-residential land use is adjacent to a residential zoning district or use (regardless of whether there is an intervening street, alley, driveway, or easement). The intent of the buffer is to provide multiple levels of screening. The buffer shall be a minimum of 25 feet wide and be planted with one tree per 20 lineal feet or fraction thereof as a combination of evergreen and deciduous planted in a staggered line. The tree requirement should include a combination of small, medium and large trees to ensure a variety of heights within the buffer. The buffer shall also include a continuous six-foot high opaque screen constructed out of plantings, a hedge, wall, fence, earth mound, or combination thereof.

(b) Existing healthy and non-invasive trees and underlying plant material located within the required buffer area shall be preserved and counted toward the perimeter landscape buffer. Protective measure should be taken to ensure the drip line and root system of the existing trees are preserved.

(c) These requirements apply when a site that is subject to these requirements is developed or redeveloped. No existing development shall be required to install perimeter landscape buffering because of a change in the nature, character, or zoning classification of an adjacent parcel.

(d) The required perimeter landscape buffer area may be located within a utility or other easement with the prior approval of the City Engineer provided all of the landscape requirements are met.

(e) Required buffer materials must be placed on the parcel where development or redevelopment is occurring, unless both the parcel providing the buffering and the parcel being buffered are in common ownership, in which case the buffer may be provided on either or portions of both properties.

(f) Vehicles or other objects shall not overhang or otherwise intrude upon the required perimeter landscape buffer. Refer to division (G)(7) of this section for curb and wheel stop requirements.

(g) Existing landscape material in good or fair condition may be used to satisfy these requirements with the prior approval of the Director.

(3) Surface parking and circulation area landscaping. All surface parking lots located within the MUR Zoning Districts that contain ten or more parking spaces and other vehicular use areas shall provide landscaping as required by this section.

(a) Street frontage screening. Surface parking lots and other vehicular use areas located within 40 feet of a public street shall be landscaped along the parking lot boundary facing the street to create a visual edge along the public right-of-way.

(b) Perimeter buffering. Where a surface parking lot is located within 50 feet of a side, or rear lot line, and the adjacent property contains a residential zoning district or use, the property owner shall install perimeter buffering meeting the requirements of division (F)(2) of this section.

(c) Interior landscaping. Parking lot islands shall be strategically distributed throughout paved parking areas and shall be consistent with section 3.4 of the MUR Design Guidelines. Interior landscaping is not required in the interior of service courts and loading docks.

(4) Foundation planting. Building foundation landscaping is required along all sides of a building facing a public street or private drive, a residential zoning district or use, open space, or facing a surface parking area located on the same lot.

(5) Use of mounding. The general design of sites shall avoid the use of uniform mounding to meet screening and buffering requirements. Integration of mounding as one of the forms of screening should focus on landforms of varying width and height that will achieve a more natural and less “engineered” appearance.

(6) Street trees. Street trees are required along all public streets per the regulations set forth in § 153.134.

(7) Tree preservation. All sites within the MUR Districts are expected to retain and protect natural features to the greatest extent practicable as part of the development process. Sites shall also comply with the procedures for §§ 153.140 to 153.149.

(G) Parking requirements.

(1) Parking shall comply with §§ 153.200 through 153.212, unless specifically provided herein. In the case of conflicts, regulations for the MUR Districts will prevail.

(2) Parking shall not be located within a setback, as outlined in Table 2, except that parking areas may extend across contiguous lots in developments with coordinated site design, shared access points and/or shared parking arrangements.

(3) Applicability. Any existing structure which does not have the minimum number of parking spaces or loading areas as required by this section, and which thereafter provides additional parking and/or loading spaces in conjunction with an improvement, shall be required to meet the minimum number of parking spaces as provided by Table 3 unless an adjustment is granted per § 153.048 (parking adjustments).

(4) Parking requirements.

(a) Minimum amount required.

1. Each use shall provide the minimum amount of parking required for that use listed on Table 3, except as may be modified by the Planning and Zoning Commission.

2. When calculating minimum parking requirements, fractional numbers shall be increased to the next whole number.

3. Unless otherwise noted, all square footage requirements are based on indoor gross floor area.

4. Except as noted in Table 3, no additional parking is required for accessory or temporary uses when the square footage of the uses is included in the parking calculation for the gross floor area of the principal use.

5. Parking and loading spaces for uses not addressed in Table 3 shall be determined by the Planning Director based on the anticipated parking impacts of the proposed use, its similarity to characteristics of other listed uses, and supporting documentation that may be provided by the applicant.

8. Applications requesting shared or phased parking arrangements; or

9. Other circumstances determined by the Director to require a parking plan, which shall be reviewed with the minor project application.

(b) A parking plan shall include, at a minimum, the following, as applicable:

1. Required parking and loading computations in accordance with Table 3 and Table 4 and the numbers of parking spaces and loading spaces to be provided.

2. Information regarding any requested parking adjustments.

3. Signed and executed easements, agreements, or other documentation required to ensure that spaces counted toward the parking requirements are properly secured.

4. Plan(s) for planned parking areas covered by the parking plan indicating locations of planned parking, names of property owners for properties not under direct control of the applicant, and any other related site details relevant to the parking plan application.

5. Any other information required by the Director to ensure an adequate review of the parking plan information.

(c) Demonstration of parking need. The Planning and Zoning Commission shall be permitted to approve a parking plan for fewer than the minimum required parking spaces based on a demonstration of parking need by the applicant. The required reviewing body shall consider:

1. The land use and development character of the area to be served by the parking facility;

2. The availability of other publicly available parking in the area;

3. The timing of parking use relative to other uses in the area;

4. The parking requirement for similar uses as may be determined by the Director;

5. Whether the provided parking meets the location requirements;

6. Whether compliance with Table 3 is made to the maximum extent practicable;

7. Whether other adjustments as described in this section should apply in conjunction with or in lieu of the requested need-based adjustment; and

8. Whether supporting documentation, if provided, adequately demonstrates that sufficient parking is available to meet projected typical demand.

9. Off-street parking requirements may be met in a shared parking lot located within 600 feet of building/structure served.

(6) Alternative parking space dimensions.

(a) A property owner may request an adjustment to parking space dimensions for no more than 5% of required parking spaces, based on documentation of a formal policy or program to encourage the use of compact vehicles by employees or visitors, as approved by the PZC.

(b) Where alternative dimensions are approved, which would have the effect of reducing the number of required spaces meeting the standard dimension requirements, the remaining standard spaces shall be subject to the deferred parking requirements.

(7) Curbs and wheel stops.

(a) Raised or rolled concrete curbs or wheel stops at least five inches high shall be installed to prevent vehicle conflicts with abutting landscape areas, sidewalks, streets, buildings, or lot lines. There shall be a minimum of four feet of clear walkway area and at least two and one-half feet between a curb or wheel stop and any property line, planting area, street, or building.

(b) Planted areas shall be installed at a lower grade than the parking lot pavement, include curbing at the edge of a landscaped area and have openings or gaps allowing drainage from the pavement to enter and percolate through the landscaped areas when used for stormwater management purposes, or if required by the City Engineer.

(c) Wheel stops may be used in conjunction with accessible parking spaces where an adjacent walkway is installed at the same grade as the parking space. Wheel stops may be used in addition to raised curbs where necessary to prevent vehicle overhang onto adjacent walkways or near buildings, or in conjunction with curb breaks used for stormwater drainage. Curbs shall be required in all other circumstances.

(8) Bicycle parking.

(a) One bicycle parking space shall be required for every 20 parking spaces required, or fraction thereof. A minimum of four spaces shall be provided whenever bicycle parking is required. Parking lots containing less than 20 spaces are not required to provide bicycle parking.

MUR-4 (joint identification)	N/A	N/A	50	8	8	6	N/A	N/A	N/A

(2) Table of numbers. The following summarizes the number of signs permitted within the MUR Zoning Districts. The intent of the Districts is that each site is permitted one monument and wall or projecting sign as its primary identification. For designated uses an additional window sign can be used to identify main entrances. An additional sign may be permitted in instances where support services available to the public area integrated within the first floor of a primary structure such as a large office complex. In no case shall more than one sign identifying a particular business be oriented toward the same property line.

Table 6: Sign Type and Number
Sign Type	Number Permitted
Wall Sign	• 1 sign per building or use. • For multiple street frontages, 1 sign per frontage, not to exceed a total of 2 (provided a minimum of 100 feet of frontage on each street). • For multi-user buildings where tenants have individual entrances, 1 wall sign per tenant space is permitted to a size as defined by the Sign Code. • In larger office/research complexes with multiple building wings connected by a shared atrium, 1 wall sign may be permitted for each wing.
Monument Sign	• 1 sign per lot or multiple lots if devoted to one specific use or user. • For multiple street frontages, 1 sign per frontage, not to exceed a total of 2 (provided a minimum 100 feet of frontage on each street).
Window Signs	• 1 sign per business or use when the use has an individual entrance (in addition to any monument, wall, or projecting sign).
Projecting Signs	• Generally limited to 1 per building or use.

(3) Joint identification signs. No more than four tenant panels may be provided on one monument sign. Tenant panels must include a frame to visually separate the individual panels.

(4) Wall signs. Based upon the specific architecture of buildings, wall signs may be administratively approved by the PZC at a greater building height, not to exceed the primary roof line.

(5) Secondary image. Secondary images for signs within the MUR Zoning Districts may be designed up to 30% of the maximum permitted area of the sign face.

(6) Sign types. To better accommodate contemporary architecture, sites permitted multiple signs may utilize a combination of sign types.

(7) Sign lighting. Signs may be illuminated per the requirements in § 153.159(E) except that no internally illuminated signs shall be located on a building wall that faces a residential zoning district or use.

(J) Site lighting. The lighting standards within this section are intended to allow adequate nighttime lighting to protect public safety while also protecting adjacent residential uses, where applicable, from excessive nighttime light and glare, protecting motorists from glare among public rights-of-way, reducing consumption of electricity for lighting purposes, and prohibiting excessive light trespass beyond property lines.

(1) Exemptions.

(a) Pedestrian walkway ground lighting; and

(3) Shielding.

(a) All exterior light sources and lamps that emit more than 900 lumens shall be concealed or shielded with an Illuminations Engineering Society of North America (IESNA) full cut-off style fixture with an angle not exceeding 90 degrees to minimize the potential glare and unnecessary diffusion on surrounding property. No portion of the lamp, reflector, lens, or refracting system may extend beyond the housing or shield, with the exception of pedestrian lighting.

(b) All light sources shall be designed, located, and installed so that the light source is not directly visible from any surrounding property in a residential district.

(4) Lighting uniformity. Lighting across a horizontal surface shall have an average range from one to three footcandles.

(5) Light trespass. Light generated on site shall not add more than one footcandle to illumination levels at any point at grade level ten feet beyond the property line.

(6) Lighting plans. Lighting plans submitted as part of applicable minor projects or final development plans shall include existing lighting from streets and surrounding buildings developed under these standards, and proposed lighting generated from light poles and building lighting.

(7) Light poles.

(a) The base of light poles in parking areas and non-parking areas shall be either flush with grade or mounted on a concrete foundation projecting no more than six inches above grade.

(b) Light poles should be a maximum of 20 feet in height.

(8) Wall lighting.

(a) Decorative wall lighting may be used to provide up-lighting, downlighting, or other types of lighting accents for buildings within the MUR Districts.

(b) Decorative lighting shall not exceed 900 lumens unless installed and shielded in accordance with this section.

(K) Utility undergrounding and screening.

(1) In the MUR Zoning Districts, all utility lines including but not limited to water supply, sanitary sewer service, electricity, telephone and gas, and their connections or feeder lines shall be placed underground.
