Article H: Form-Based Zones and Standards This page intentionally left blank P-1A Creating a Solid Foundation for the Form-Based Zones and Standards The Form-Based Zones and Standards implement the Iowa City's Comprehensive Plan vision through the application of zones and standards that reflect a context-specific approach to community character based upon the City's distinct development patterns. These patterns include the historic downtown area and surrounding neighborhoods developed prior to World War II, newer subdivisions and commercial corridors developed since World War II, districts providing employment and services, and natural areas including waterways. These Form-Based Zones and Standards address the walkable development patterns and the natural contexts with standards that carry out the community's expectations reflected in the Comprehensive Plan. P-1B Guiding Principles The Form-Based Zones and Standards are guided by the following principles in implementing the Comprehensive Plan: 1. Across the City, the Form-Based Zones and Standards: A. Promote, preserve, and enhance community design and character in support of the community's vision of a college town with a variety of neighborhoods; downtown as the cultural and commercial heart of the community; and neighborhoods with centers along pleasant and convenient corridors that connect the City; B. Reinforce the urban pattern of a central downtown and waterfront core, employment centers and mixed-use walkable districts, residential neighborhoods, and multi-modal corridors with centers serving as amenities and focal points for community activity; C. Remove barriers to revitalization and reinvestment; D. Ensure appropriately-scaled infill development; E. Support a diversity of housing choices appropriate to their location; F. Ensure that each building plays a role in creating a better whole, not just a good building; and G. Promote development patterns that support safe, effective, and multi-modal transportation options for all users and help reduce greenhouse gas emissions. Preamble: A Community Character-Based Approach to Zoning 1Admin Draft — October 2019 Iowa City - Article H: Form-Based Zones and Standards 2. Within districts and employment centers, the Form-Based Zones and Standards: A. Reinforce downtown as a cultural and commercial destination accommodating appropriate-scaled infill housing, mixed-use, and cultural development compatible with existing historic fabric; B. Facilitate transitions from single-use employment centers to mixed-use districts that are compatible with adjacent residential neighborhoods and public access; and 3. Within residential neighborhoods, the Form-Based Zones and Standards: A. Protect character of established neighborhoods and build upon and reinforce the unique physical characteristics of the City's pre-WWII neighborhoods; B. Support walkable neighborhood patterns through networks of well-designed multi-modal streets that are safe for pedestrians and bicycles; and C. Promote neighborhoods with quality housing and a diversity of context-sensitive housing choices. 4. Along corridors, the Form-Based Zones and Standards: A. Promote a variety of housing choices to shape each corridor; B. Promote small local businesses as an important part of the City's economy; C. Promote incremental infill and revitalization; D. Enable neighborhood main streets as centers to become vibrant social and commercial focal points, with services and amenities for the surrounding neighborhoods located within a safe, comfortable walking distance of homes; E. Balance pedestrian comfort and place making with traffic efficiency; and F. Promote and accommodate high-quality community design at key gateways in the City. P-1C Classifications of Different Context Types in Iowa City The City is characterized by different context types that reflect its pre- and post-World War II development patterns. Historic districts and neighborhoods developed prior to WWII tend to be more pedestrian-oriented, with smaller development blocks, consistent sidewalks, more intense development patterns and services, shopping and/or transit within short walking distance. Newer areas of the City tend to be more auto-oriented, with larger blocks and less amenities within short walking distance. The Form-Based Zones and Standards apply a community-character-based approach to the City that is based upon the classification of three distinct context types. Each context type —Natural, Walkable, and Auto- Oriented Suburban—needs to be regulated differently in order to effectively reinforce the intended context. Walkable and Natural Context Types are most effectively regulated with form-based zones, which apply primarily to mixed-use centers, corridors, and neighborhoods. The Auto-Oriented Suburban Context Type is most effectively regulated through conventional use-based zoning. Figure P-1C-1 (Context Type Descriptions) provides full descriptions of each context type. 2 Admin Draft — October 2019Iowa City - Article H: Form-Based Zones and Standards P-1C The Auto-Oriented Suburban Context Type consist of areas developed mainly after the 1950's. This type of development is driven by the priority to accommodate the automobile. Characteristic of this context type, land uses are segregated and often buffered, leaving large distances between them requiring the automobile for day-to-day functions. Walking and cycling occur in these areas, but generally for recreational rather than destination purposes due to lack of connectivity and amenities within short walking distance. Examples of these areas are commercial big box retail, strip mall centers, single-family residential subdivisions, and industrial areas. These areas typically have a higher environmental impact per capita than Walkable Contexts because of the high degree of land consumption and separation of uses. These areas are implemented through Conventional, use-based zones.Auto-Oriented Suburban ContextThe Walkable Context Type is where a person can walk, bike or ride transit to work to fulfill most shopping and recreation needs. These areas allow for but do not require the use of a vehicle to accommodate most daily needs. These areas, primarily developed prior to the 1940's, were developed in a pattern where a person could live with limited reliance on the automobile and are conducive to destination walking and cycling. These areas are supported through a network of interconnected, tree-lined streets, a diversity of housing choices, and a mix of appropriate commercial and residential uses in a compact form. These areas also support public transit due to their compact nature. These areas are implemented through the T3–T5 Form-Based Zones.Walkable ContextThe Natural Context Type consist of undeveloped land interspersed throughout the City and along its periphery. In these areas, nature dominates a person's experience, but may include an occasional recreation-oriented or utility building or other man-made feature. The use of cars is integrated, but does not dominate the character of natural areas. The proximity of natural areas to the developed portion of the City is an important component in defining the City's unique character. These areas are implemented through the T1 Form-Based Zone.Natural ContextFigure P-1C-1: Context Type Descriptions 3 Admin Draft — October 2019 Iowa City - Article H: Form-Based Zones and Standards P-1C 4 Admin Draft — October 2019Iowa City - Article H: Form-Based Zones and Standards This page intentionally left blank P-1D A Hybrid Approach for Iowa City In zoning, a hybrid zoning code brings together the zoning and operating systems of form-based zoning and conventional, use-based zoning to address the unique qualities of the context types that make up a community. In general, form-based zoning is applied to Walkable Contexts, and conventional, use-based zoning is applied to Auto-Oriented Suburban Contexts. This hybrid approach directs development and uses within each context type to thrive with standards that respond to their respective, unique needs and objectives. For example, a neighborhood main street is regulated through form-based zoning with the intention that the standards will generate walkable development. Standards encourage buildings to be scaled to the pedestrian and to existing and future neighboring buildings, and placed to shape a public realm for pedestrians. Uses are less important than the overall environment and public realm that the uses can occupy. A suburban strip mall is regulated through conventional, use-based zoning with the intention that the standards will generate Auto-Oriented Suburban development. Standards control uses, overall heights and intensities with less predictability as to their placement on a site or how each building shapes the public realm. In this hybrid approach, the Form-Based Zones and Standards are applied only to walkable development and conventional, uses based zones and standards continue to apply to Auto-Oriented Suburban development. What is a Form-Based Code? Form-Based Coding (FBC) represents a paradigm shift in the way that the built environment is regulated. The formal short definition of a Form-Based Code is as follows: Form-Based Codes foster predictable built results and a high-quality public realm by using physical form (rather than separation of uses) as the organizing principle for the code. These codes are adopted into city or county law as regulations, not mere guidelines. Form-Based Codes are an alternative to conventional zoning. -Form-Based Codes Institute Unlike conventional, use-based codes, FBCs utilize the intended form and character of a context type, rather than use as the organizing framework of the code. Further, FBCs regulate a series of important elements not just to create a good individual building, but a high-quality place. The terminology in FBCs reflects the intended physical form and hierarchy of different places. For example, instead of a zone being labeled "commercial" or "mixed use," it might be called "main street." The term "main street" ties back to the intended physical form or place, which includes a mix of uses, civic spaces, thoroughfares, frontages, and building types that create vibrant walkable urbanism. It is also important to note that while FBCs primarily regulate the intended physical form, they regulate use secondarily. FBCs allow a range of uses that are carefully chosen to maximize compatibility between uses and the intended physical form of the zone. The use tables are simplified and categorized by use type, and clearly defined, to allow a greater degree of administrative decision-making related to particular uses. Most FBCs use an organizing principle called the Natural-to-Urban Transect. This enables a customized framework of zones for a community that are based on intended physical character, as is explained in the following sub-section. 5 Admin Draft — October 2019 Iowa City - Article H: Form-Based Zones and Standards P-1D The Natural-to-Urban Transect: The Framework for the Form-Based Code The Natural-to-Urban Transect is the organizing principle used in most Form-Based Codes (FBC). It establishes a hierarchy of physical environments or 'zones' from the most natural to the most urban. The designation of each zone along this hierarchy is determined first by the character and form, intensity of development, and type of place, and secondly by the mix of uses within the area. This hierarchy of physical environments becomes the framework for the entire FBC, replacing use as the organizing principle as in conventional, use-based zoning. Each transect is used to reinforce existing or create new walkable environments. The Natural-to-Urban Transect is a means for considering and organizing the human habitat in a continuum of intensity that ranges from the most natural condition to the most urban. It provides a standardized method for differentiating between the intentions for urban form in various areas using gradual transitions rather than harsh distinctions. Each transect is primarily classified by the physical intensity of the built form, the relationship between nature and the built environment, and the complexity of uses within the transect. ~ Form-Based Codes Institute The model transect for American communities is divided into six individual transects: Natural (T1), Rural (T2), Sub-Urban (T3), General Urban (T4), Urban Center (T5), and Urban Core (T6), together with a District (D), often referred to as a Special District, designation for areas with specialized purposes (e.g., heavy industrial, transportation, or university districts, among other possibilities). Each T-zone is given a number. Higher numbers designate progressively more urban zones, and lower numbers designate less urban and natural zones. The City's form-based zones are customized based on the T1, T2, T3, T4, T5, and T6 Transects.

For human environments, this cross-section can be used to identify a set of habitats that vary by their urban character, in a continuum ranging from rural to urban. This range, rural to urban, provides a rational basis for organizing the components of the built work: buildings, lots, land use, open space, streets, all elements of the human habitat. Form-based coding describes the desired volume of buildings and their interaction with public space.

Walkable is described as an environment that is pedestrian-oriented in nature, where bicycling and walking are viable daily options because services, retail, or restaurants are within a short walking distance of most residences. 14-2H-1E Relationship to Title 14 (Zoning Code) Article H (Form-Based Zones and Standards) is coordinated with Title 14 (Zoning Code) as described in Table 14-2H-1E-1 (Relationship to Title 14 (Zoning Code), Title 15 (Land Subdivision) and Title 18 (Site Plan Review)). 15Admin Draft — October 2019 Iowa City - Article H: Form-Based Zones and Standards Introduction 14-2H-1E Note to City Staff: Sub-Section 14-2H-1C Quick Code Guides, need to be revised after trip no.3 Table 14-2H-1E-1: Relationship to Title 14 (Zoning Code), Title 15 (Land Subdivisions), and Title 18 (Site Plan Review) Title 14 Chapter Description Status 1 Introductory Provisions Article H (Form-Based Zones and Standards) relies on this Chapter. 2 Base Zones Replaced by form-based zones within form-based zone boundaries.

The Form-Based Zones are for the purpose of generating and supporting the variety and physical character of the intended natural and walkable environments. 14-2H-2B Form-Based Zones 1. Form-Based Zones and Standards. This Section describes the form-based zones and standards. Each zone is established based on the intent of the desired physical form and character of the environments described in the Preamble of this Article. These zones focus on mixed-use, walkable environments and range in function and intensity from primarily residential to areas with a mix of lower intensity building types (T3 Neighborhood Edge), to moderate intensity neighborhoods (T4 Neighborhood Medium) and centers (T4 Main Street) to high intensity neighborhoods (T5 Neighborhood General) and centers (T5 Main Street) to a regional-serving downtown (T6 Core). The naming of the form-based zones is based on a spectrum of context types in the City from less urban to more urban as listed in Table 14-2H-2B-1 (Iowa City Transect). Section 14-2H-2: Form-Based Zones Table 14-2H-2B-1: Iowa City Transect T1 T2 T3 T4 T5 T6 Natural Rural Walkable Neighborhood General Urban Urban Center Urban Core Less Urban More Urban Form-Based Zones Neighborhood Center Reserved Main Street Main Street Reserved Core ReservedNaturalRural Developed Reserved Rural Natural Reserved Neighborhood General Neighborhood Edge Neighborhood Medium Neighborhood Small Neighborhood General Reserved A zone identified as reserved denotes a zone that will be needed when this Article is applied to areas needing that form-based zone. 17Admin Draft — October 2019 Iowa City - Article H: Form-Based Zones and Standards 14-2H-2C Sub-Zones 1. Sub-zones are slight variations of the base zone, are parcel-specific, and mapped on Figure 14-2H-2D-1 (Regulating Plan). This Article includes two types of sub-zones: A. Open. The open sub-zone is applied for either or both of the following purposes: (1) To allow more uses than the base zone allows in specific areas but within the same form and character of the base zone; and/or (2) To more easily allow certain uses that are already allowed in the base zone. In this way, the open sub-zone can provide additional flexibility to lots located at or near intersections that function or can function as a neighborhood node of non-residential uses. B. Limited. The limited sub-zone is applied for either or both of the following purposes: (1) To allow less uses than the base zone allows in specific areas, within the same form and character of the base zone; and/or (2) To further restrict certain uses already allowed in the base zone for specific areas. 2. Table 14-2H-3B-1 (Uses) identifies the sub-zones and its requirements for the particular uses. 14-2H-2D Regulating Plan The zones established in this Article are mapped on Figure 14-2H-2D-1 (Regulating Plan). In addition to identifying the zoning for each parcel, Figure 14-2H-2D-1 (Regulating Plan) identifies specific urban design requirements. 14-2H-2E Form-Based Zones Overview Table 14-2H-2E-1 (Form-Based Zones Overview) provides an overview of each zone and its intent. This information is to show how the broader transects in Table 14-2H-2B-1 (Iowa City Transect) have been applied and, as background on the intended physical character, allowed range of uses, and direction for the detailed standards in each zone. 18 Admin Draft — October 2019Iowa City - Article H: Form-Based Zones and Standards Form-Based Zones Figure 14-2H-2D-1: Regulating Plan 19Admin Draft — October 2019 Iowa City - Article H: Form-Based Zones and Standards Form-Based Zones Note to City Staff: Figure 14-2H-2D-1 Regulating Plan, Plan in progress.

Building Types are categorized into two groups: House-Scale buildings and Block-Scale buildings. House- Scale buildings are those that are the size of a house, typically ranging in footprint from as small as 25 feet up to 80 feet overall. Block-Scale buildings are individually as large as most or all of a block or, when arranged together along a street, appear as long as most or all of a block. 2. The lot size standards for each building type are set in each zone to generate pedestrian-oriented buildings. The lot size standard identifies the range of lot sizes on which the given building type is allowed to be built. 3. Each lot shall have only one primary building type, except as follows: A. Where allowed by the zone and as allowed in Sub-Section 14-2H-7D (Carriage House), one Carriage House is allowed in addition to the primary building type; B. The Cottage Court (Sub-Section 14-2H-7I) may consist of up to nine individual Cottages; C. More than one building type is allowed on a parcel that identifies proposed multiple lot lines that meet the standards of this Section. See Figure 14-2H-7B-1 (Example of Multiple Lots on an Existing Parcel). 14-2H-7C Overview Table 14-2H-7C-1 (Building Types Overview) provides an overview of the allowed building types. The names of the building types are not intended to limit uses within a building type. For example, a House Large may have non-residential uses within it, including, but not limited to a restaurant or office, as allowed by the zone. Section 14-2H-7: Building Type Standards 87Admin Draft — October 2019 Iowa City - Article H: Form-Based Zones and Standards Figure 14-2H-7B-1 Example of Multiple Lots on an Existing Parcel Existing parcel.

Provide a range of thoroughfare types to support the intended physical character of each zone. 2. Provide only thoroughfares that are multi-modal and interconnected in a network that disperses vehicular traffic with multiple routes to destinations. 14-2H-11B Complete Streets Each improvement to existing streets and the design of new streets is required to be reviewed by the City to ensure compliance with the following: 1. Multi-Modal. Each street serves all users by balancing the needs of automobiles, transit, and service vehicles with those of pedestrians and cyclists. This is done in different ways depending upon the situation and ultimately intended to provide many options for moving throughout the City. 2. Context Sensitive. Each street is designed to accommodate the different users while working with the existing or intended physical context of the area to enhance the appeal of adjacent real estate. 3. Substantial Compliance as to Location. Where Figure 14-2H-2D-1 (Regulating Plan) identifies the required location of a new Thoroughfare Type, its location is approximate within 100 feet in either direction of the identified location. Substantial compliance for the purposes of this requirement mweans that the required thoroughfare must be within 100 feet of the identified location. Review for compliance is part of the City's review of the associated Walkable Neighborhood Plan (WNP) per Section 14-2H-5 (Walkable Community Design Standards). Section 14-2H-11: Thoroughfare Type Standards 161Admin Draft — October 2019 Iowa City - Article H: Form-Based Zones and Standards 14-2H-11C Thoroughfare Types 1. This Section identifies the allowed thoroughfare types consistent with the intended physical character of each zone. 2. The individual standards of each thoroughfare type in this Section may be adjusted administratively by the Director. In considering adjustments, the Director of Public Works and the Director of Neighborhood Development services shall make the following findings. The proposed adjustment: A. Supports the intended physical character of the zone(s). B. Maintains multiple modes of transportation (transit, pedestrian, bicycles, automobiles). C. Maintains sidewalks at least six feet wide. D. Maintains on-street parking for a majority of each block face. E. Maintains regularly spaced street trees. 3. Additional thoroughfare types may be developed, subject to City review and approval, using the components and standards in Sub-Section 14-2H-11P (Intersections), Sub-Section 14-2H-11Q (Pedestrian Crossings) , and Sub-Section 14-2H-11R (Curb Radius). 14-2H-11D Overview Table 14-2H-11D-1 (Thoroughfare Types Overview) provides an overview of the allowed thoroughfare types.

More regular encroachment of turning vehicles into opposing lanes will occur at compact intersections. Therefore, frequency of access, traffic volumes and the speeds on intersecting streets at those intersections shall be considered when designing intersections. For fire and rescue, determination of the importance of that street for community access is to be considered in the design of intersections, (e.g. primary or secondary access). 2. The designer shall use turning templates or software to evaluate intersections to ensure that adequate operation of vehicles can occur. Location of on-street parking around intersections may be evaluated during this analysis to identify potential conflicts between turning vehicles and on-street parking. Bike lanes and on-street parking will increase the effective curb return radius, when curb extensions are not applied, by providing more room for the wheel-tracking of turning vehicles. 3. Roundabouts are to be considered as an alternative to traffic signals. Roundabouts provide reduced vehicle speeds, reduced conflict points, separation of vehicle-vehicle conflict points from vehicle- pedestrian conflict points, and provide a two-step crossing for pedestrians. At multi-lane roundabouts, benefits for bicyclists and pedestrians are greatly diminished due to multiple-threat scenarios and bicycle weaving, so additional considerations are necessary, including installing a traffic signal or other appropriate traffic safety feature. 177 Thoroughfare Type Standards Admin Draft — October 2019 Iowa City - Article H: Form-Based Zones and Standards 14-2H-11P 14-2H-11Q Pedestrian Crossings Table 14-2H-11Q-1 (Pedestrian Crossings) provide standards to be applied in the design process for improvements to existing streets and in the design of new streets. Table 14-2H-11Q-1: Pedestrian Crossings Type Description Directional Curb Ramps Diagonal corner ramps are preferred when feasible. When not feasible, perpendicular corner curb ramps with a separate ramp installed in each direction shall be used. Crosswalks Crosswalks shall be designed per the City's applicable standards and applicable State/County guidelines and standards. Medians Medians, where provided, shall provide a median refuge at the intersection. At signalized intersections, median refuges shall not be used to stage pedestrians. Pedestrians shall be accommodated to get entirely across the roadway.10' min.12' or length of crosswalk min.Mid-block Crossings Mid-block crossings, where provided, require approval of the Public Works Director and shall have mid-block curb extensions and cross signals. 178 Thoroughfare Type Standards Admin Draft — October 2019Iowa City - Article H: Form-Based Zones and Standards 14-2H-11Q 14-2H-11R Curb Radius Table 14-2H-11R-1 (Curb Radius) provides standards for the curb radius when improving existing intersections or designing new intersections.

The purpose of this Section is to provide regulations for nonconforming uses, structures, developments, and lots that were lawful before the adoption or amendment of Article H (Form-Based Zones and Standards) but which are no longer in conformance with current applicable standards. 2. The Section is intended to encourage the continuing improvement of existing nonconforming uses, structures, developments, and lots by limiting the extent to which they may continue to be used, altered, expanded, and moved, or replaced, while allowing for reasonable improvements for appearance, maintenance, and safety, consistent with existing regulations. 3. Exceptions for nonconforming situations in Article H (Form-Based Zones and Standards) area are also provided. 14-2H-12B Exceptions for Form-Based Zones 1. This Sub-Section establishes provisions to allow for reinvestment in nonconforming uses, structures, developments, and lots in form-based zones to achieve public safety, aesthetic, environmental, economic or fiscal benefits to support the long-term goals of the City. Nonconforming situations in the zones may be expanded, enlarged, and improved in a manner not entirely consistent with Article E (Nonconforming Situations) of Chapter 4 (Use Regulations) in Title 14 (Zoning Code) if the following findings are made by the Review Authority: A. It can be demonstrated that the nonconforming situation provides an economic, fiscal, public health, safety, aesthetic, or environmental benefit to the community; B. The change does not significantly extend or expand the existing structure’s floor area or the intensity of the situation unless the extension or expansion brings the structure into more conformance with applicable standards in Sections 14-2H-2 (Form-Based Zones) or 14-2H-4 (Site Standards); C. Any extension or expansion in the life of any nonconforming situation results solely from the improved operational efficiency and is incidental to the primary purpose of improving public health and safety or providing economic, fiscal, aesthetic, or environmental benefits; and D. Any changes will not unreasonably impede implementation of the Comprehensive Plan over the long-term. 2. Compliance with the number of parking spaces required may not be prioritized over other standards during review of the exceptions in this Sub-Section.
