Sidewalks. Sidewalks having a minimum width of five feet shall be installed within the right-of-way along any street frontage serving the property and align with adjacent public sidewalks. In the event public sidewalks are not present, the alignment shall be determined by the community development director. Sidewalks that connect the building entrance(s) to the public sidewalk shall also be installed. All such sidewalks shall be installed at the sole expense of the developer or property owner. Unless otherwise provided, a landscaped area having a minimum width of five feet shall be maintained between the back of curb and sidewalk. Sidewalks may be incorporated into the landscaping, but shall not displace required landscaping. See article 7, Parking and Loading.

(Ord. No. 7-2020, § 1(Exh. A), 10-26-20)

Sec. 3.2.4.1.- Purpose.

The general commercial district is to acknowledge the auto-dependent character of the historic development pattern along Riverdale's arterials such as Highway 85 and Highway 138. This district protects the substantial investments made by the owners of such properties and the contribution of these businesses to Riverdale coffers. Application of the North American Standard Industry Classification (NASIC) uses to these commercial corridors and the interpretive authority of the community development director established in section 9.2, Interpretive authority of the community development director or the zoning administrator affords substantial flexibility in the range of allowed uses. This flexibility will enable business owners to better tap into the market demand represented by the very significant traffic volumes on these corridors.

(Ord. No. 7-2020, § 1(Exh. A), 10-26-20)

Sec. 3.2.4.2.- Allowed uses.

(Ord. No. 7-2020, § 1(Exh. A), 10-26-20)

Sec. 3.3.1.- Purpose.

The intent of city council in adopting the office-institutional district and the hospital overlay as well as the associated standards of this section is to: (1) foster office and institutional development that not only brings expanded services to residents, but expanded employment opportunities as well; (2) promote design and relaxed development standards that will yield quality and more intensive office development; and (3) encourage medical related uses to the exclusion of incompatible and non-complementary uses to support establishment of a dynamic medical center for both professional employment and accessible medical services.

(Ord. No. 7-2020, § 1(Exh. A), 10-26-20)

Sec. 3.3.2.- Office-institutional land uses by zoning district.

The following zoning districts comprise the office-institutional districts in the City of Riverdale:

"O-I" office-institutional district.

"H" hospital overlay.

(Ord. No. 7-2020, § 1(Exh. A), 10-26-20)

Sec. 3.3.3.1.- Purpose.

The O-I district is a typical office-institutional district that should be promoted by Riverdale as a source of high paying jobs. As with the majority of zoning districts in the ordinance, the O-I is an exclusive district, prohibiting low density residential development that could compete with office development in a market where vacant land is limited. Given that reality, development standards that foster high intensity development, in combination with the reservation of open space, are intended to create park-like settings that will attract and sustain office tenants and employees. Institutional uses such as places of worship and schools of all types are also allowed in the O-I District. Buffers and setbacks can facilitate an appropriate transition from office and institutional uses to either neighborhood commercial districts or multifamily districts that would be appropriate uses to step down from O-I District uses to single-family detached neighborhoods.

(Ord. No. 7-2020, § 1(Exh. A), 10-26-20)

Sec. 3.3.3.2.- Allowed uses.

(Ord. No. 7-2020, § 1(Exh. A), 10-26-20)

Sec. 3.6.1.- Purpose.

Located just outside Atlanta, the City of Riverdale has long desired to create a town center area to be the focus of development and redevelopment; a walkable community center where residents are able to live, work, and play. The concept of developing a town center was introduced in the early 2000s, with plans becoming a reality when city hall, a community center, an amphitheater and open space, and a public parking deck were completed in 2010.

With these public improvements in place and with renewed growth of the Metro Atlanta area, the city is in a position to promote development within the town center mixed-use (TCMU) district. The TCMU district standards and related architectural and urban design standards seek to establish the desired mixed-use development necessary to establish a viable town center while maintaining clarity and flexibility in zoning.

(Ord. No. 7-2020, § 1(Exh. A), 10-26-20; Amd. of 7-24-2023(2))

Sec. 3.6.2.- Guiding principles.

Support mixed-use development. The intent of the TCMU district is to create a separate location with retail, residential, office and civic uses that collectively create a walkable, mixed-use setting that is people friendly with parking. New residential, commercial, office, and institutional development will provide the opportunity for people to live, work, shop and engage in civic and cultural activities.

This is accomplished with the development of vertical mixed-use, with retail, restaurants, or office on the lower floors and residences above. Development in the town center should include medium to high-density mixed-use buildings with above ground-floor residential and townhouses. Residential density is an important component of a successful mixed-use area to support walkable retail and restaurants. Compatibility with adjacent development in terms of density and intensity is necessary and shall be considered. Higher residential density and higher intensity commercial uses should be established near similar existing development and along prominent corridors. Mixed-use development will promote employment, residential, commercial and cultural opportunities and enrich the varied social life of the TCMU district.

Promote a pedestrian-oriented environment through design. New development should focus on human-scale design that is compatible with the Riverdale context to create a walkable environment that accommodates all ages and abilities. Streetscape elements shall complement building form and orientation to create a well-defined pedestrian zone. The visitor experience shall be enhanced through the provision of community amenities, including but not limited to sidewalks, crosswalks, street trees, lighting, and pedestrian oriented spaces. In addition, connections to open spaces, public buildings and public transportation shall be included in the network of pedestrian infrastructure.

Establish a unique architectural identity for Riverdale that balances consistency and variety. The design standards established in the architectural and urban design standards apply to development within the TCMU district and are intended to ensure that new buildings are compatible with existing and future development in the district. Variety in architectural elements is encouraged to define a unique character for Riverdale.

(Ord. No. 7-2020, § 1(Exh. A), 10-26-20; Amd. of 7-24-2023(2))

Sec. 3.6.3.- Applicability.

These standards apply to all proposed development within the TCMU district that is subject to site plan approval. Development within the TCMU district is also subject to the architectural design standards set forth in article 5, Architectural Design Standards. Planning commission, at its discretion, may ap-prove minor deviations from the design standards if, in the opinion of the commission, such deviations contribute to the principles articulated in section 3.5.2 more effectively than strict compliance with specific standards. Applicants shall clarify how proposed deviations advance the goals of the town center as defined by the guiding principles. These design standards do not exempt applicants from obtaining all required permits and complying with all applicable building codes, laws, and regulations in force.

(Ord. No. 7-2020, § 1(Exh. A), 10-26-20)

Sec. 3.6.4.- Land uses.

Generally. Land uses shall provide an orderly relationship and function with other uses in the development, including existing land uses. Land uses shall also be consistent with the 2018 comprehensive plan update, Riverdale's livable centers initiative (LCI) town center study, and Riverdale Zoning Ordinance. A combination of the following use types are allowed in the mixed-use district as presented in section 3.0, Uses Table 3, provided a minimum of two use types per lot, including commercial, retail, residential or office/institutional, are proposed.

Commercial, office and institutional uses. The TCMU district shall consist of commercial (retail and service) uses, office uses, and institutional uses. Commercial development in this district should be limited to uses that are compatible with a traditional town center setting. Commercial establishments in TCMU districts shall be consistent with the desired character and functionality of this area as defined in sections 3.5.1 and 3.5.2 of this article.

Residential uses. The TCMU shall consist of residential uses as specified in this section.

Mixed-uses. Development within the TCMU District should provide a minimum of one "mixed-use" building that includes a combination one residential component and a minimum of one commercial component, or similar combination of uses that supports the intent of this district. A common example of this scenario is a building with upper floor residential units above commercial/retail-oriented uses. A combination of use types are also allowed in the TCMU District as presented in section 3.0, Uses Table 3, provided a minimum of two use types per lot or development site, including commercial, retail, residential or office/institutional, are proposed.

Open space. Open space shall be required as set forth in section 3.6.5, Development standards.
