14-2G-4: FRONTAGE TYPE STANDARDS
A. Generally
A building's frontage condition—the transition from public to private space, from indoor to outdoor at the
main entrance, the design treatment of ground floor building facade the configuration of facade projections,
and the disposition of improvements within required setbacks—stro gly influences the quality and character
of public streets and spaces.
All principal buildings in the form -based zoning districts shall be d signed with Frontage Types meeting the
requirements of this section. The standards recognize that differe t types of buildings—as defined in the
Building Type standards in the subsequent section—may call for different frontage conditions. Illustrations
within this section are intended to demonstrate basic frontage ype standards and are not intended to
promote a particular architectural style or represent the archit ctural detail necessary for high quality
buildings.

a. The private frontage area between the public id e alk and the building facade shall be designed for
additional sidewalk width and other pedestri -one ed uses, such as plaza space, outdoor patio space
for restaurant and cafe seating, landscaping public art, r recessed entryways.
b. To encourage commercial activity at the st eet level, priva frontage areas should be seamlessly
integrated with and at the same level as t e public sidewalk the extent possible. With approval of the
FBC Committee, on sloping sites in speci is locations where the is a desire to provide usable outdoor
space the private frontage area may be s ghtly raised above sidew grade to create a level plaza or patio
area. The elevation of the raised area sh II not exceed the elevation the ground floor finished floor (see
2.d below). A transparent, decorative ought iron or similar metal railing may be located at the edge of
the raised area if required for safety, b t shall be limited to 42" max. in height. Opaque railings, fences or

33
establishments, as approved by the City. Any such fencing/railings for outdoor service areas and sidewalk
cafes must include landscaped planters or planter boxes along at least 50% of its length.
c. A minimum 70% of the tetal area of the ground floor facade between 2 and 10 feet in height above
adjacent ground level shall consist of storefront window and doors. Glazing shall be clear and highly
transparent and individual lites for display windows should a as large as possible to invite views into the
interior space. Transom windows are encouraged above sto efront display windows. Residential window

The Urban Flex frontage is a frontage type appropriate for buildings with ground floor commercial uses
where more flexibility is desired for non -retail uses, such as offices, institutional uses, building trade uses,
and live -work uses, or along secondary frontages where views into the interior of the building are not as
34
critical, but where architecturally finished facades with elements that provide visual interest and comfort
to pedestrians are important. See Table 2G-5 to determine appropriate building types. The frontage
provides ground floor storefront conditions with high proportions of transparency, but to a lesser degree
than the Storefront frontage.

14-2G-5: BUILDING TYPE STANDARDS
A. Generally
A
The Building Type Standards differentiate and define a range of principal building typologies deemed
appropriate for the Riverfront Crossings District and the Eastside Mixed Use Subdistrict. The Building Types
describe basic building configuration and massing, pedestri n access, vehicle access, and parking specific to
each typology. The standArds are intended to complemen the Subdistrict Standards and Frontage Type
standards set forth in previous sections. Illustrations are i tended to demonstrate basic Building Type
standards, and are not intende to promote a particular a chitectural style or represent the architectural detail
necessary for high quality buildin s. In the event of con icting requirements the more stringent requirement

Eastside Mixed -Use District
-------------- _

Why create a new

zoning district?
In 2015, the City's Central Planning District was
amended to include this area.
Create a better transition from Downtown Iowa City
to the eastside residential neighborhood.
Establish zoning standards to ensure that
redevelopment is compatible with the character and
scale of the surrounding neighborhood.
A form -based zoning district is a good tool to achieve
these goals.

Current zoning is not a good fit
Forces developers to
build commercial and
mixed-use building
types in an area where
demand for commercial
uses is limited.
Residential uses are not
allowed on the ground
floor.
Mm
Current Zoning - Why it is not a good fit
Forces buildings to be
built lot line to lot line
with little or no green
space in an area where
landscaped front yards
are the norm.
Allows buildings that are
out of scale with adjacent
residential buildings.
Most of the existing
buildings are
nonconforming with the
current zoning

Benefits of the Form -based Code
Form -based Codes are
organized around form and
character rather than use and
density
In the EMU District:
• Similar residential densities
allowed as current Central
Business zoning, while ensuring
building forms that fit into the
residential character of the area.
• Mix of uses possible, but fine-
tuned to ensure a better
transition from Downtown
• Code is tailored to ensure
that the size and placement
of buildings and parking are
consistent with the existing
neighborhood

Street, and Washington Street
Size:
Approximately 7.4 acres
Existing Land Use and Zoning:

File Date:

45 Day Limitation Period: August 21, 2016
BACKGROUND INFORMATION:
In May of 2015, City Council amended the City's Comprehensive Plan to incorporate portions of
the blocks between Van Buren and Johnson Streets, south of Jefferson Street and north of
Burlington Street into the Central Planning District. This area has historically been considered a
transitional area between downtown Iowa City and the residential neighborhoods to the east. In
addition to incorporating this area into the Central Planning District, the City Council established
a goal to develop zoning code amendments to address site and building design standards,
building height and scale, and setbacks to ensure that any redevelopment in this area is
2
compatible with the character and scale of the traditional residential neighborho eeoPyo
downtown Iowa City. Staff has drafted a form based code to create the Eastside Mixed -Use
(EMU) zoning district to help implement the comprehensive plan vision for this area as outlined
in the associated memo in July 21 P&Z meeting packet.
Once the zoning code text amendments are adopted, the properties within the EMU District
must be rezoned in order for the new form -based standards to apply. Staff recommends
rezoning all properties within the EMU District to the new zoning designation to ensure that any
future redevelopment is consistent with the Comprehensive Plan.
The City notified all property owners and surrounding property owners of the proposed rezoning
and held a "good neighbor" informational meeting on June 22, 2016 (see attached letter) to
discuss the new form -based zoning and address questions from area property owners. Staff also
met individually with area property owners to discuss the proposed zoning.
ANALYSIS:
The properties that are the subject of this rezoning are located in the Central Planning District
and primarily contain homes constructed in the early part of the 20th century. Some infill
apartments of more modern design are present. Commercial buildings, such as the University of
Iowa Community Credit Union, New Pioneer Co-op, a small office building, and a gas
station/convenience store are all located along Van Buren Street. A new, larger mixed-use
building was recently constructed on Washington Street in accordance with the CB -2 zoning
standards.
The current zoning of properties in this area is largely Central Business Service (CB -2) or
Central Business Support (CB -5). These central business zones encourage high density urban
mixed use development by requiring new buildings to be designed as mainstreet-style
commercial buildings that require commercial uses on the ground level floor and may have
residential uses on the upper floors with little or no building setbacks from the street or from
adjacent properties. There are two properties zoned RNS-20 that are included in the EMU
District. These properties contain multi -family buildings that are not consistent with the
standards in the EMU District, so the rezoning may create an incentive for redevelopment.
With this proposed area -wide rezoning, the new form -based zoning standards of the Eastside
Mixed Use (EMU) form -based code district will apply to all properties within the designated
boundaries of the EMU District, specifically the portions of the 500 blocks of Iowa Avenue,
College Street, Washington Street, and Burlington Street illustrated on the attached map.
STAFF RECOMMENDATION:
Staff recommends approval of REZ16-00006, a proposal to rezone approximately 7.4 acres of
property between Van Buren and Johnson Streets, south of Jefferson Street and north of
Burlington Streets from CB -2, CB -5, and RNS-20 zones to Eastside Mixed -Use District (EMU)
zone.

Planning and Zoning Commission
July 21, 2016—Formal Meeting
Page 8 of 12
Dyer moved to defer the amendments to the Title 14, Zoning Code to establish standards
for a new form- based code district, the Eastside Mixed Use District, to clarify and refine
the language of certain provisions of the Riverfront Crossings form -based code, to
adjust parking requirements and apartment mix standards to encourage student housing
in areas abutting the University campus and to encourage housing for a broader mix of
populations throughout Riverfront Crossings and the Eastside Mixed Use Districts; and
to ensure that zoning requirements for exterior lighting are applied in the Riverfront
Crossings and Eastside Mixed Use Districts.
Theobald seconded the motion.
A vote was taken and the motion passed 5-0.
j REZONING ITEM (REZ16-00006):
Discussion of an application submitted by the City of Iowa City for a rezoning of multiple
properties encompassing portions of the 500 blocks of Iowa Avenue, College Street,
Washington Street and Burlington Street from Central Business Support (CB -5}, Central
Business Service (CB -2) and Neighborhood Stabilization Residential (RNS-20) to Eastside
Mixed Use (EMU)
Howard said this item is to rezone all the properties located within the boundaries of the new
Eastside Mixed Use District. Once the zoning code text amendments are adopted, the
properties within the Eastside Mixed Use District must be rezoned in order for the new form -
based standards to apply. Staff recommends rezoning all properties within the Eastside Mixed
Use District to the new zoning designation to ensure that any future redevelopment is consistent
with the Comprehensive Plan. The City notified all property owners and surrounding property
owners of the proposed rezoning and held a good neighbor informational meeting on June 22,
2016 to discuss the new form -based zoning and address questions from area property owners.
Staff also met individually with some area property owners to discuss the proposed zoning.
Staff is recommends deferral of this item until the Code Amendments creating the Eastside
Mixed Use zoning district are recommended for approval.
Freerks opened the public hearing.
Pam Michaud (109 South Johnson Street) noted her appreciation that no alcohol sales business
would be allowed in this area and would encourage shop hours to be controlled. Michaud stated
she is glad to see this proposed form -based code is limiting the three bedroom units. However,
she is concerned about new businesses in the area, having hours of operation that are
disruptive to nearby residents, such as DP Dough restaurant that is open until 4 AM. She stated
that if the City wants to make these new form -based districts attractive for long term residents
and not just students that these types of things need to be taken into account, such as hours of
operation, lighting, etc.
Hektoen clarified the Code Amendment does not say no alcohol sales (for example, restaurants
can sell alcoholic beverages), but there are restrictions on drinking establishments and alcohol
oriented retail uses. Howard added that the new EMU District would not allow any new drinking
establishments or alcohol sales -oriented uses in this area. Hektoen clarified that restaurants
that serve alcohol are distinguished from drinking establishments based on the hours of
operation.

Signs questioned why D.P. Dough is allowed to stay open until 4 a.m. Howard replied that they
do not serve alcohol so they can set their business hours. Signs questioned why the code could
have detailed standards such as the opacity of glass in the storefronts or other details that make
buildings fit into the neighborhood, why couldn't it specify hours of operation so there is a better
fit into character of the neighborhood. Howard noted that Staff would take a look at that issue
and understands the concern.
Freerks closed the public hearing.
Parsons moved to defer REZ16-00006 an application submitted by the City of Iowa City
for a rezoning of multiple properties encompassing portions of the 500 blocks of Iowa
Avenue, College Street, Washington Street and Burlington Street from Central Business
Support (CB -5), Central Business Service (CB -2) and Neighborhood Stabilization
Residential (RNS-20) to Eastside Mixed Use (EMU).
Theobald seconded the motion.
A vote was taken and the motion carried 5-0.
REZONING ITEM (REZ16-00004):
Discussion of an application submitted by Larry Digman on behalf of Veterans Liberty Center for
a rezoning from General Industrial (1-1) zone to Intensive Commercial (CI -1) zone for
approximately 35,000 square feet of property located at 2114-2118 S. Riverside Drive and 103
Commercial Drive.
Miklo showed an aerial photo of the location of the property and the two buildings that are on
the property. It is somewhat unique that it is a commercial condominium regime, there are three
condominiums in each building. Three are owned by the Veterans Liberty Center, a non-profit
services organization for veterans. They currently lease out part of that space to an auto repair
shop. The other three condominiums are owned by a contractor/cabinet maker, a construction
company and the third one is owned by the contractor/cabinet maker but leased to a coffee
roasting company.
Miklo said that the auto repair shop moved in not knowing that their use was not allowed in an I-
1 zone. This came to the City's attention when the auto repair shop inquired about expanding
the business to include car sales. Car sales are also not allowed in the 1-1 zone. Therefore the
Veterans Liberty Center approached the City about rezoning the property. During that
discussion it was discovered they did not own the entire property, they only owned their
condominiums. So the staff had discussions with the other two condominium owners and they
did express some concern about car sales. With their business there is a lot of heavy truck
traffic and they need to be assured the docks in the back of the business are accessible They
were concerned that retail customers for a car sales lot would interfere with their use of the
driveway to their buildings.
There was a meeting of all the condominium property owners and they agreed to go along with
the rezoning of their property subject to the car sales being limited to the front of the property
and no retail traffic would come to the back of the property.
Miklo also noted that a letter was received from an adjacent person who has a property to the
east who is also concerned about the CIA zone and the outdoor storage that it allows. He noted
that outdoor storage is also allowed by the current 1-1 zoning that applies to the property.
Planning and Zoning Commission
August 4, 2016 — Formal Meeting
Page 3 of 6
Theobald moved to approve the amendments to Title 14, Zoning Code as described in the
Staff Report of July 27, 2016 and amended in the Staff Memo of August 4, 2016.
Parsons seconded the motion.
Parsons noted that this land with its close proximity to downtown and the historical
neighborhoods to the east will be a desirable area in the future and it is obvious that this code
amendment has been well thought out by Staff.
Signs stated he likes the addition of the set business hours to keep the goal of maintaining that
neighborhood transition.
Freerks asked if property owners were made aware of this change, as there was no public
present this evening. Howard noted the business operation hours wouldn't affect any of the
businesses that are there now, any that are currently open after 11 will be grandfathered in. She
noted that required notifications of this meeting and agenda were followed.
