Re: WA 4-47 Task 5 Final Market Overview Memo for Iowa City
Deliverable 5c
Introduction
This memo summarizes the market conditions in the Riverfront Crossings District, exploring, in
particular, opportunities for residential and mixed-use commercial development. This summary
can be used to provide market context and background information needed to facilitate informed
discussions with key stakeholders as Iowa City’s planning effort progresses. As a summary
document, this memo relies mainly on secondary sources for demographic, land use and
market analysis data. While some of the data reviewed was assembled two years ago1, Iowa
City has experienced some of the most stable market conditions across the country, in part
because it is a recession-resistant college-town, with a captive market2. Current market
conditions and land use patterns were confirmed by discussions with the Iowa City Planning
Department and the community workshops that occurred November 11 – 13, 2009.
The context for this market assessment is two-part. Riverfront properties in the Riverfront
Crossings District were devastated by the floods of 2008, making redevelopment mandatory.
These floods and subsequent destruction led planners to reassess the risks of development
within the floodplain. It is likely that properties at high flood risk will be rezoned as open space
and left undeveloped to minimize future potential damage. This redevelopment presents a
unique opportunity to develop new neighborhood park-land and design an amenity-rich
community that will appeal to existing residents, employers and employees as well as attract
new residential and commercial opportunities.
In addition to necessary redevelopment due to flooding, the district has become a focal point in
discussions regarding transit-oriented development (TOD) in Iowa City. If additional funding is
secured from the State, an Amtrak station could be located in the district in the historic Rock
Island Railroad Depot. This station would provide rail access to Chicago and other major cities
throughout the Midwest. In addition to the Amtrak station, there is an opportunity to provide
access to local passenger rail in the Iowa City/Cedar Rapids region, through the creation of two
transit stops in the district. The CRANDIC rail line is ideally located to provide service from the
heart of the district to the University campus, the University and Veterans hospitals, and

downtown Iowa City as well as a connection to Coralville’s River Landing development, North
Liberty and eventually Cedar Rapids3.
While the reality of transit access in the district is not immediate, it is important that any post-
flooding redevelopment anticipate these opportunities and prepare a neighborhood fabric that
could support TOD around the proposed stations. Transit access often has the ability catalyze
neighborhood development; with proper planning and infrastructure in place the district can
position itself to be Iowa City’s first TOD community. With convenient and cost-effective
transportation links to downtown, the University and other local employment centers as well as
larger cities in the Midwest, the Riverfront Crossings District would be a prime site for smart
growth development; complete with higher density housing, which would in turn support mixed-
use retail and services, entertainment venues, and restaurants.
In preparing this summary, ICF reviewed recent Iowa City market studies, interviewed members
of the City’s Planning Office and participated in a team debrief session to get feedback from the
November workshop. The reports reviewed as secondary sources include:
• Community Profile, City of Iowa Economic Development Division, 2007
• Downtown Iowa City Market Niche Analysis, Iowa City, Iowa, November 2007
• 2007 Iowa City Apartment Rent Survey
• Iowa City Metro Area Affordable Housing Market Analysis, December 2007
• Market and Financial Analysis for a Mixed-Use Development at 434 S. Linn Street, 2009
• City of Iowa Central District Plan, Department of Planning and Community Development,
October 21, 2008.
Community Profile
The first step to any market analysis is an examination of the current community context, both in
terms of existing land use as well as demographics. This community profile will detail the current
land use and zoning patterns in the Riverfront Crossings District, specifically exploring existing
commercial, public and residential uses so that we may understand how the current
neighborhood fabric can accommodate the proposed TOD. Secondly, the community profile will
explore the demographics of the existing and anticipated target markets (community residents,
business owners, employees, university students and visitors) and identify trends that will have
an impact on the demand for the proposed development.
Zoning and Land Use
Before delving into the immediate project area, it is important to understand the broader
neighborhood character and dominant land uses that are at play. Iowa City, well known as the
home to the University of Iowa, is consistently ranked one of the best places in America to live4.
The University, with enrollment of roughly 30,000 as well as 18,000 employees is the single,
largest entity in the region, and its influence on the city and surrounding region is significant. For
the purpose of this study, that influence translates into a stable recession-buffer and increasing
housing and consumer market demand. As enrollment and University real estate development
continues, the market for local housing and goods continues to expand. The University is one of
the main engines of the local economy.
The Riverfront Crossings District is currently defined as the area bounded by Burlington
Street/State Highway 1, the Iowa River, Highway 6, and Boyrum/ Van Buren Street, however,
the district boundaries may be extended westward across the river as a result of the November
workshop discussions. Current zoning patterns site industrial and public/institutional/University
3 While rail was not the focus of this analysis, more information can be found Cedar-Iowa River Rail Transit Project Feasibility Study, November 2006
4 Iowa City Metro Area Affordable Housing Market Analysis, Mullin & Longergan Associates, December 2007
land uses in the north/west portion of the district and general commercial, office and mixed-use
as well as small pockets of residential zoning in the eastern portion. Residentially-zoned land
exists to the east of the site. Based on these zoning patterns, the common land uses in the
project area include a large public waste water treatment plant (which is set to relocate), a
recycling plant, University of Iowa auxiliary buildings (adjacent to the main campus directly to
the north) and various public buildings such as the county administrative offices, and a number
of smaller retail, office and business service establishments as well as some scatter-site
residential. The majority of the residential uses, located in the northern portion of the district,
include multi-family residential dwellings populated predominantly by University students. The
northern portion of the district has somewhat of a downtown feel, however, due to fast-moving
traffic along Highway 1/Burlington Street it is disconnected from downtown Iowa City5. Slower
moving traffic and the availability of on-street parking have attracted a small-scale retail and
personal service district along Kirkwood Avenue, east of Gilbert Street. This area includes some
of the elements of a more traditional main-street commercial zone in terms of scale and
pedestrian orientation. Many of these smaller establishments are locally owned and have been
in business for a long time, providing needed goods and services to local residents. Additionally,
the properties along Gilbert Street have been transitioning away from intensive commercial uses
toward retail commercial uses, although quite a number are the type that require outdoor
storage and display. A small pocket of residential uses exist in the northeastern corner of the
project area. Residential neighborhoods directly to the north and east of the district contain
housing from several different periods, creating a unique patchwork of housing styles ranging
from small contemporary ranch houses to 1900’s era vernacular houses and grand Victorian-era
houses. The Oak Grove Neighborhood Association is active in the neighborhood in the
northeast corner of the district.
The Floods of 2008, which affected properties north of Highway 6 and west of South Dubuque
Street, provided an impetus to redevelop the district. One aspect of this proposed
redevelopment is to limit development on the floodplain and introduce community open space;
another is the siting of local as well as regional transit stops in the neighborhood. The flooding
of 2008 has caused planners to reassess the risks of development within the floodplain and in
the interest of minimizing the impacts of future floods, any future development or
redevelopment, particularly residential development, in these areas must take the floodplain and
its inherent risks into account. It is likely that properties at high flood risk will be designated as
open space and left undeveloped. The city is already in discussions about relocating the waste
water treatment operations that are currently located along the river to the City’s other treatment
plant6. Only two small parks exist just east of the district: Oak Grove Park and the tiny Highland
Park. This new open space could provide much needed recreation land for the neighborhood.
Furthermore, development of trails and attractive park space along the river may encourage
redevelopment and reinvestment in the area. The concept of designating flood-prone land along
the river for parkland received a lot of support from stakeholders who attended the November
workshop. There was definite buy-in for restricting development on the 100-year flood plain,
although consensus was not reached about limiting development in the 500-year flood plain.
Furthermore, there was great enthusiasm for open space, including a series of parks and
working landscape, such as community gardens. Eighty-two percent of workshop participants
polled indicated that they thought a new riverfront park was a great idea and 44% (the most
common response) indicated that they would use the park weekly. Moreover, 74% supported
the use of tax payer dollars to create such park land.
There is also a proposal to locate an Amtrak station in the center of the district at Lafayette and
Clinton Streets. Furthermore, the CRANDIC rail line runs along Maiden Lane, however, there
are currently no rail stops in the project area. Early discussions have identified a possible light
rail stop in the heart of the project area, north of Lafayette Street, between Clinton and Dubuque

as well as an additional stop in the northwest corner of the project area, adjacent to the
University buildings. The siting of the proposed transit stops could be a catalyst for dramatic
land use shifts in the neighborhood. If the proposed passenger rail service and Amtrak station
are constructed, the district would become an ideal neighborhood for TOD and could support
high density mixed-use development around the train depot and transit stops. Proposed zoning
changes would create a district of intense commercial uses along South Gilbert Court and a
district of commercial and urban mixed-use along Gilbert Street. Adoption of an overlay zoning
district tailored to this important commercial district could help to create a more uniform and
attractive streetscape as redevelopment occurs, and will ensure that it redevelops with a
pedestrian orientation to serve nearby residents, shoppers and employees who are accessing
the neighborhood by transit, high-density residential development and a different mix of retail
businesses and services.
In addition to the proposed transit stops creating a new and expanded market, the district has
already began to transition. Land north of the rail line is being developed to support spillover
demand for downtown housing. As downtown housing bleeds southward, demand for services
and retail will not be far behind.
Demographics
In addition to the zoning and land use implications of redevelopment, it is critical to take into
account the demand of the target market. In Iowa City this market consists of a diversity of
stakeholders, including community residents, business owners, employees, university students
and visitors. The demographic characteristics of the local and regional population can have a
significant impact on what type of development is feasible and what land uses can be
economically supported. In addition to a basic understanding of the general population, it is also
important to explore the characteristics of any niche markets that might be attracted to the
unique offerings of development in the district. Other than the downtown area, which offers
upscale, urban residential housing, the Iowa City region is largely comprised of low-density,
suburban housing stock. The proposed Riverfront Crossings District development will offer a
mixed-income, mixed-use, transit-oriented, urban neighborhood that will likely appeal to various
segments of the young professional market, often dubbed the ‘creative class.’ The term ‘creative
class,’ coined by Professor Richard Florida, has been used by economic development
professionals across the country to describe and attract this desired demographic.
Understanding the demographic trends of the creative class is therefore a key piece of
understanding and capitalizing on the unique market demand of the district.
The most captive market is comprised of those who currently live or work in Iowa City. The
demographics of this market will almost certainly drive commercial as well as housing demand
in the district. The 2008 population of Iowa City is estimated at 67,841. The regional Iowa City
MSA, which consists of Johnson and Washington counties, has an estimated 2008 population of
149,437 while the broader Cedar Rapids/Iowa City Technology Corridor has an estimated
population of 404,8897. Not only does this region boast a significant population in terms of its
size, it has been growing annually and projections indicate that it will continue to outpace the
state’s growth rate by double at the city-level and by triple at the MSA-level. Many people are
relocating to Johnson County from surrounding counties; in 2000 the county had a net-gain of
3,0008. This strong growth is critical to supporting the demand for housing and commercial uses
in the district.

2008.
8 Iowa City Metro Area Affordable Housing Market Analysis, Mullin & Longergan Associates, December 2007
Secondly, the region performs well in terms of socioeconomics. The Iowa City MSA has a lower
than statewide unemployment rate9 and a robust city-wide median household income of
$40,378 and a median family income of $67,22910. Roughly 70% of the city-wide and 67% of
the regional population is employed in white collar jobs. The Iowa City MSA is tied with
Stamford, Connecticut, for the US metropolitan area with the highest percentage of the adult
population holding a bachelor's degree or higher; with 44 percent of adults holding a degree.
The University and its accompanying health care services employ a significant portion of the
local population, supporting nearly 30,000 jobs combined. The socioeconomic profile of the local
and regional residents indicates that Iowa City has a strong and growing market.
In addition to general population demographics, it is important to take into account niche
markets that might be uniquely drawn to TOD-style development in the district. Iowa City is
commonly known as a "college town" as it is home to the University of Iowa, with a student
enrollment of 30,000 and a small campus for Kirkwood Community College. As often is the
case in college towns, many young people choose to stay in the region after graduation;
therefore it is not surprising that the median age is relatively low, 27.6 in Iowa City and 30.3 in
the greater region, compared to the Iowa average of 39. Nearly 20% of the local residential
market area is comprised of young professionals age 25-34, well above the state average of
12%. These young professionals comprise the broader ‘creative class’ market niche. The
creative class, generally attracted to high-density, affordable, urban living, will be drawn to
amenities such as transit accessibility, proximity to entrepreneurial opportunities and cultural
centers downtown as well as proposed riverside open space, making them an ideal market for
the Riverfront Crossings District redevelopment.
ESRI Business Information Solutions developed a market classification tool that identifies 65
neighborhood market segments, or community tapestries, based on a variety of demographic
and socioeconomic characteristics and other determinants of consumer behavior. These
community tapestry segments can be used to identify key cultural aspects of demographic
cohorts. The top five market segments present in regional Iowa City MSA are: Aspiring Young
Families (13.8% of households), Enterprising Professionals (10.9%), Crossroads (7.6%), Dorms
to Diplomas (7.3%), and College Towns (6.9%) while the top five in the local city market are:
Enterprising Professionals (17.2% of households), Dorms to Diplomas (13.5%), College Towns
(12.8%), Metropolitans (10.9%), and Young and Restless (10.6%)11. The descriptions of these
market segments can be useful in identifying the residential and commercial preferences for the
population cohorts that reside in Iowa City and the surrounding region.
The below paragraphs provide descriptions of the demographic characteristics of the niche
cohorts12 that are particularly relevant to the district redevelopment. Later in this summary we
will use to these descriptions to understand the residential decisions and consumer preferences
of the Iowa City market.
Most Aspiring Young Families residents are young, startup families, a mix of married-couple families with and without
children and single parents with children. The average family size is 3.13, near the U.S. average. Approximately two-
thirds of the households are families, 27% are single-person households, and 9% are shared. Annual population
growth is 1.7%, higher than the U.S. growth. The median age is 30.4 years; nearly one-fifth of residents are in their
20s. This market is ethnically diverse. Although most residents are white, other race groups are also represented.
Seventeen percent of residents are black, and 16% are of Hispanic origin. The median household income is $47,200,
and income is derived mainly from wages. The median net worth for this market is $94,300. Approximately 60% of
employed residents have professional, management, sales, or office/administrative support positions. Overall, 85% of
residents aged 25 years and older have graduated from high school, 35% have attended college, and 22% hold a
bachelor’s or graduate degree.

With a median age of 24.5 years, College Towns is the fourth youngest of all the Tapestry segments. Most residents
are aged between 18 and 34 years and live in single-person or shared households. One-fourth of households are
occupied by married couple families. The racial profile of this market is similar to the U.S. profile. Three-fourths of the
residents are white. Education is the key focus of College Towns residents. Approximately 41% of residents are
enrolled in college or graduate school, often at the local college or university. Other residents are on the teaching and
research staffs, because many continued to work at the college they attended. Naturally, College Towns residents are
educated; 40% of residents aged 25 years and older have a bachelor’s or graduate degree. Because many students
only work part-time, the median household income of $28,900 ranks near the low end. Fifty-two percent of the
employed residents in this market are part-time workers. This segment ranks second to the Dorms to Diplomas
segment for the highest proportion of part-time employment. Most of the employed residents work in the service
industry, holding on- and off-campus jobs in educational services, health care, and food preparation. The median net
worth for this market is $30,700.
Crossroads neighborhoods are primarily home to married-couple families with and without children and single-parent
families. These residents are young, with a median age of 31.9 years. Householders tend to be younger than the U.S.
average; half of them are younger than 45 years. The population in this segment is growing more than 1.6% annually,
a faster rate than the U.S. population. Eighteen percent of residents are Hispanic. Although 73% of residents are white,
other racial groups are represented in this market. The median household income for this market is $39,500,
somewhat below the U.S. median; the median net worth is $46,000, less than half the U.S. value. Educational
attainment levels are lower than U.S. levels; only 36% of residents aged 25 years and older hold a bachelor’s or
graduate degree or have attended college. Most of the employed residents work in the manufacturing, construction,
retail trade, and service industry sectors. Labor force participation is comparable to the U.S. level, but unemployment is
slightly higher.
Dorms to Diplomas residents are college students who represent the youngest of all the Community Tapestry
segments, with a median age of 21.8 years. Approximately 81% of residents are enrolled in a college or university. The
rest of the population are not students and reside off campus. Approximately 42% of the households share housing
with one or more roommates; 38% are single-person dwellings. Ethnic diversity is relatively low for this segment.
Approximately 73% of the residents are white and 11% are Asian. To support themselves while they attend school,
nearly three-fourths of the employed residents work part-time in low-paying service jobs. The median household
income for this segment is $17,600; the median net worth is $13,100. Approximately 52% of the residents aged 25
and older hold a bachelor’s or graduate degree. The educational institutions at the center of these communities employ
many residents, especially in the educational services, accommodation/food services, and retail trade industry sectors.
This market is home to young, educated, working professionals. Single or married Enterprising Professionals residents
are singularly young, with a median age of 32.4 years. Forty-three percent of households consist of singles who live
alone or with roommates. Similarly, 43% of households consist of married-couple families. The number of households
in this market is approximately 2% of U.S. households but is one of the fastest-growing markets with household growth
of 2.6% annually. The diversity of the population is similar to that of the United States. The majority of residents are
white; however, 11% are Asian (more than two and one-half times the U.S. level). Household income exceeds
expectations, with a median of $66,000. The median net worth of $150,900 is growing. Ninety percent of Enterprising
Professionals households derive income from wages and salaries; 39% have some form of investment income. This is
an educated group: 46% of the population aged 25 years and older hold a bachelor’s or graduate degree and 30%
have attended college. Nine percent are enrolled in college or graduate school. Ranked second of all the Community
Tapestry markets for labor force participation at 75%, these working professionals are employed in various jobs,
especially management, finance, computer, sales, and office/administrative support occupations.
Metropolitans residents favor city living in older neighborhoods. Approximately half of the households are composed of
singles who live alone or with others. However, married-couple families comprise 40% of households. Compared to the
United States, there is a higher proportion of residents aged 20–34 in this market. The median age is 37.1 years.
Diversity is low; a white population dominates. At 71%, labor force participation is well above average; the
unemployment rate of 5% is below average. Metropolitans residents are educated: 75% of the population aged 25
years and older have attended college or completed a degree program; 28% hold a bachelor’s degree, and 21% have
a graduate degree. Half of employed persons hold professional or management positions. The median household
income is $57,600. Nearly half of the households earn income from interest, dividends, and rental properties. The
median net worth is $134,500.
Change is the constant for Young and Restless households. This young, on-the-go population has a median age of
28.9 years. Slightly more than one-half of them are younger than 35. Fifty-nine percent of these households are either
single person or shared. Neighborhoods are diverse. Sixty percent of the residents are white; however, there is an
above-average representation of other cultures including 19% who are black, 8% who are Asian, and 18% who are
Hispanic. Socioeconomic: The median household income is $40,900, and the median net worth is $87,000. Although
the median household income is below the U.S. median, because only 23% of these households include children,
discretionary income is higher than for segments with similar income levels. Young and Restless is an educated
market; one-third of residents aged 25 years and older hold a bachelor’s or graduate degree and another one-third
have attended college. Thirteen percent are enrolled in college or graduate school. Career is a common element
shared by these ethnically diverse residents. Both men and women participate in the labor force at much higher rates
than the U.S. rates. The 75% labor force participation rate is the highest among all the Community Tapestry segments;
the female labor force participation of 73% is also the highest. Most employed residents work in professional, sales,
service, and office/administrative support positions.
Lastly, in addition to understanding the demographics of permanent residents, the visitor market
must be considered as it can have a significant influence on commercial demand. According to
a recent market analysis report, roughly 50,000 tourists are attracted annually by Iowa City’s
River and Jazz festivals. The downtown Sheraton Hotel books 2,570 night rooms per year.
Additionally, the University, with major events and attractions ranging from sports and arts to its
top-of-the-line health care facilities, attracts over 1.5 million local and nationwide visitors
annually. Overall, Johnson County ranked fourth of Iowa’s 99 counties for tourism dollars with
over $244 million in domestic travel spent in 200513.
Housing Demand
Housing demand is directly related to household demographics; therefore this section will begin
by reviewing the demographic findings identified in the previous section in the context of certain
regional housing trends. The strong demographic trends identified in the previous section are
indicative of a growing market for housing in the district. Between 1990 and 2007 population in
the Iowa City MSA grew an average of 1.63% annually and household growth had an average
annual growth of 2.34%.14 While 2012 projections indicate slightly slower rates for the next five-
year period, the region will continue to grow more quickly than the state and will add an average
of 1,064 new households to the residential market area annually. Market area population is
projected to reach nearly 170,000 with nearly 70,000 households in 2012. Moreover, the
number of households is growing faster that overall population growth. This trend can be seen
throughout the country, and is indicative of smaller family size, however, in particular for Iowa
City, it might mean a subtle shift from dorm-style living with 5-6 unrelated roommates to housing
for couples and young families. When the number of households grows faster than total
population, it sparks housing demand as an increase in units is required to accommodate the
same number of people15.
A more in-depth look at income by age trends identifies three distinct residential markets in Iowa
City, the college and immediate post-college individuals, the ‘creative class’ professionals and
lastly the older, more affluent demographic. Not surprisingly the most affluent age cohort is the
householders between 45 and 64 and the lowest income group are those in the college / post
college cohort. Nearly 40% of college/post-college market (householders under 25 years old)
has incomes below $15,000. This is in sharp contrast to both the creative class and older
professional cohorts. Over 30% of those 25-34 years old and over 40% of those 35-44 years old
have household incomes between $50,000 - $100,000. In Iowa City the creative class will be
particularly important to the newly developing housing market. In addition to their socioeconomic
characteristics, there are other cultural elements of this market demographic that will be
discussed in further detail below that make this group particularly interested in higher-density,
urban living.

14 Downtown Iowa City Market Niche Analysis, Iowa City, Iowa, Marketek, November 2007
15 Iowa City Metro Area Affordable Housing Market Analysis, Mullin & Longergan Associates, December 2007
As identified by the tapestry data, the two largest regional market segments are Aspiring Young
Families and Enterprising Professionals with 13.8% and 10.9% of households, respectively.
While the residential preferences of the former segment favor single family detached homes or
townhouses, the latter enjoy living in newer, higher density housing and prefer to own rather
than rent. Other top market segments whose members tend to live in high density, mixed-use
environments are College Towns (6.9% of households), Metropolitans (6.3%) and the Young
and Restless (5.8%)16.
Housing Supply
This section will profile the existing housing supply in Iowa City, including housing
characteristics and sale and rental market price trends. This current profile will act as a
foundation for understanding the future residential demand. The table below summarizes the
most salient characteristics of the existing housing supply. As can be seen, while Iowa City is
pretty evenly split between renters and owners, the majority of units in the MSA are owner-
occupied. The high percentage of renters in Iowa City can be attributed to college students and
young professionals, who are typically renters. City and MSA owner and rental unit values are
consistent with a slight price premium for rental units in the city. In both the city and MSA, the
most common housing type is single family, detached, however, 10+ unit structures comprise
over a quarter of units in the city, compared to only 17% in the MSA.

The number of issued building permits is strong indicator of the future housing supply. In Iowa
City, the number of issued permits for residential buildings has declined across all structure
types since 2002/2003, when it was at a ten-year high. At the MSA level, the total number of
permits declined, however, single family permits increased at 1% annually18.
Price is another key indicator. Home prices in the Iowa City region increased roughly 5%
annually from 2001 to the first quarter 2007. Iowa City, like other college towns across the

country, has fared fairly well compared to other regions, despite the national real estate crisis19.
A healthy job market has supported growing housing demand that has offset some of the
negative impacts of the nationwide economic turmoil. Forty-one percent of residential sales in
Iowa City in 2006 were in the less than $150,000 categories, while 67% of sales were under
$200,000. The largest proportion of sales, almost one-third, was in the $100,000 to $150,000
range and more than a quarter of sales were in the $150,000 to $199,999 range. Sales over
$300,000 comprise only 10% of total sales20. Local sales trends indicate that condominium
sales have also been strong. With a few exceptions, condominium units in these areas have
historically been characterized as either “apartment style” or “suburban style” units, with prices
that generally top out at around $125,000.
This analysis will focus on the apartment-style condominium market, as it is likely that this is the
type of housing stock to be developed in the Riverfront Crossings District. Moreover,
discussions at the November workshop confirmed that there is a strong market for this type of
development as there is a current lack of for-sale units targeted towards young professionals.
The urban rental market in Iowa City is bifurcated between units marketed toward University of
Iowa students and apartments targeted at professionals. According to Cook Appraisal, there
were an estimated 1,852 rental units in downtown Iowa City in 200721. Downtown is an ideal
location for students and professionals who work downtown, thus, rents tend to be higher than
in non-downtown Iowa City. The average downtown rent in 2005 was $747. It is estimated that
rents have increased by 3% to 4% over the past few years to roughly $770. Non-downtown
rents are estimated at roughly $69822. The vacancy rate in downtown is estimated at roughly
2% and roughly 4.5% in the rest of the city. Vacancy rates have been relatively stable over the
past few years. The low rates indicate a tight apartment market, particularly downtown, that is
likely due to demand from students and young professionals seeking housing near school or
work. This demographic would similarly be attracted to housing in the Riverfront Crossings
District as it also offers transit-accessible, proximate, urban, mixed-use living. Again, looking at
comparable units in the rental market provides us with a sense of what can be expected for the
proposed units in the district23.
Apartments marketed toward students are typically three- to four bedroom units in mid-rise
buildings with fewer than 100 units and ground-floor retail. A good example of student-focused
housing is the recently completed Telluride Building at 355 S. Linn Street. The development
contains roughly 5,400 square feet of ground floor commercial space with four floors of student
apartments in the form of 1 to 5 bedroom units. The development also includes approximately
40 parking slots24. The student residential units are almost fully occupied, however, the first floor
commercial is vacant25. In addition to student-oriented apartments that dominate the Iowa City
rental market, there are a few higher-end rentals in downtown Iowa City that target graduate
students, professionals and young couples. Rents for these units run from moderately priced
one-bedrooms at $660 to nearly $3,000 penthouses. Rents generally cover all utilities, as well
as community amenities such as a spa/sauna, fitness center, basketball court, game room and
tanning room. In-unit amenities include equipped kitchens, furnished living and bedrooms and
walk-in closets. The price per square foot ranges from $1.44 to $1.90. These units experience
few vacancies and tend to lease in December for the following fall26. A good example is the

Moen Group’s Plaza Towers, a 14-story, mixed-use high-rise that was developed on a
pedestrian mall in downtown Iowa City in 2005. The residential component of the building
initially consisted of 28 for-sale condo units and 27 rental apartment units. The initial
condominium pricing was roughly $210/SF, with an additional $13,000 for parking. However,
prices rose quickly after the first few units sold and continued to increase as the units sold out.
In the end, six of the 27 rental units were sold as condominiums. In 2007, units were valued at
roughly $350/SF ($450/SF for penthouses) with an additional $18,000 for parking. The price
point of the downtown condo market ranges from $150,000 to $230,00027.
Housing Demand
As one aspect of the Downtown Iowa City Market Niche Analysis, Marketek conducted a
statistical demand assessment for the residential for-sale and rental market. The report cautions
that despite the fact that finite numbers were used for the analysis, the end result should be
interpreted as an approximation of market depth, balanced by the ever-changing characteristics
of the competitive supply. New household growth and turnover are the two main sources of
potential housing demand. New household growth is traditionally used to project market growth
and is based on population and household growth projections. The owner and renter analyses
use the average annual increase in households beginning with the estimated household base in
2007 and the projected 2007-2017 annual increase in new households. For both the for-sale
and rental market, the more significant source of potential demand is turnover, which is
estimated by owner and renter turnover rates derived from census data and preference
information from the household tapestry data. The results of this analysis conclude that annually
from 2007 - 2017, there will be 906 residential households who will potentially buy newly
developed higher density market rate housing. Additionally, there will be an estimated 1,298
new renters of market rate, urban units.
New housing development in the district will be particularly well positioned to satisfy the growing
demand for housing in Iowa City and regionally. The district can support higher-density infill
housing and its proximity to the heart of downtown Iowa City and nearby recreational and
cultural activities will mean that it can target the same demographic as the downtown housing
market. The city-wide growth of professional jobs and proposed University expansion plans
suggest that the traditional downtown area will need to extend southward into the district in the
near future. Demand from developers of student housing has already been expressed, and two
new apartment buildings are being developed on the north-side of the district.
One of the best methods of evaluating the strength of a new market is by looking at comparable
proposed developments. The Linn Street Market Assessment conducted in March of 2009
determined that it was feasible to develop approximately 90 affordable and market rate
condominium units at the project site in the northern portion of the district. The sales rates
ranged from approximately $219 to $325 per square foot, meaning that a typical 800-square-
foot one-bedroom affordable unit would be $175,000, and the market-rate price for a similarly
sized unit would be $300,00028. Another project, the Hieronymus Square Tower was sited for
314-328 South Clinton Street, also along the northern border of the district. The project is
currently on-hold due to financing, however, once it is completed it will contain 114
condominiums, including a mix of workforce and high-end units. In addition to residential space,
it will contain 9,000 square feet of retail space, 39,400 square feet of commercial space, and
from three to four floors of condominium office space. Lastly, another development is proposed
for 228 E. Court Street, at the site of the St. Patrick’s Church School. The demolition of the
existing buildings will likely occur in 2010 pending the decision to proceed with the construction
of the proposed mixed-use facility, including 25-75 units of workforce (affordable) housing,
27 Ibid
28 Market and Financial Analysis for a Mixed-Use Development at 434 S. Linn Street, 2009
25,000 – 35,000 square feet of commercial space and a parking facility to accommodate
approximately 600 parking spaces29.
These projects are indicative of the type of development that can be expected throughout the
district. While ‘comparables’ are a good indicator of demand, it is important to remember they
represent single sites and thus need to be considered against a broader area market
assessment. Demand is greatly affected by location and amenity characteristics, and thus
demand for these units will not apply to all residential development in the district, nor do they
attest to the overall district demand.
The Downtown Iowa City Market Niche Analysis conducted in 2007 provides an assessment of
the downtown housing market. For many reasons the market assessment of downtown’s
potential demand is relevant for the Riverfront Crossings District. Most importantly, mixed-use
development in the district will appeal to a similar market demographic in search of urban,
transit-accessible living. The Riverfront Crossings District is considered a less expensive
alternative to downtown and retaining affordable housing in the district is very important to the
community, according to stakeholders who participated in the November workshop. As it is
expected that the district development will continue to be more affordable than downtown
development, we can assume that district development will actually attract a wider demographic
that includes the downtown market as well as those that would be priced out of downtown.
Marketek estimates that from 2007 to 2017 downtown Iowa City has the potential to absorb
approximately 2,257 units of market rate for-sale and rental housing. It is expected that 39% (or
874 units) will be for-sale units, while 62% (or 1,383 units) will be rental properties. Marketek
estimates that downtown Iowa City has the potential to capture 9.7% of residential market area
demand for higher density, for-sale product and 10.7% of residential market area demand for
higher density, rental product over the next ten years. It can be expected that mixed-use
residential development in the district can capture a similar percentage. Using recent regional
home sales and the socioeconomic demographics of the residential market, opening price
points for urban housing should range from $150,000 to $230,000. Smaller, more affordable
units will likely appeal to first time homebuyers, while larger, more expensive units will appeal to
more established professionals30. Although there is clearly demand for units priced above
$350,000, this market is better served in the downtown area, where existing market demand
can support the prices. Housing in the district should include affordable units that would appeal
to the area’s workforce and recent graduates who are launching their careers.
Current rental market trends and occupancy rates in other high-density neighborhoods, such as
downtown, suggest a strong market that could support rents in the range of $800 to $1,200 for
one-bedroom units that offer a unique set of amenities such as ample parking, balconies,
laundry facilities, dishwashers/disposals, cable-readiness and high-speed internet (i.e. not
targeted towards the student market)31. New housing in Iowa City’s urban areas should target
upwardly mobile households as well as affordably priced workforce housing to providing a
variety of options that meet the needs of the city’s workforce and creates diverse vibrant and
sustainable communities.
Returning again to the tapestry data analysis, we can identify niche segments of the population
that are likely to have the highest demand for urban, mixed-use housing in the district. Entry-
level professionals, higher-level professionals, creative professionals and students are likely to
be the most important segments for new urban housing. Additionally, with those markets in
mind, certain amenities become particularly important. The descriptions below detail the niche
29 Iowa City Planning Office 30 Downtown Iowa City Market Niche Analysis, Iowa City, Iowa, Marketek, November 2007

demographics, price points, key amenities that should be considered for new residential
development in the district32.
Entry-level Professionals: This market segment consists of recent college graduates age 25 to 35 employed in
professional careers. Most households consist of a single person or couple, with few having children. Household
income ranges from $30,000 to $75,000. Higher income households ($45,000 to $75,000) are potential buyers of
housing priced from $150,000 to $250,000, while lower income households ($30,000 to $45,000) are potential renters
of units priced from $750 up. Consumer survey results indicate that most members of this age bracket interested in
living in downtown Iowa City would prefer to own condominiums or lofts with two to three bedrooms and two baths.
Parking garages, windows/natural light and affordability were the top ranked housing features by this group.
Higher-level Professionals: Households within this market segment are composed of 1 or 2 persons, some with
children, age 30 to 50 employed in professional occupations. Having advanced in their careers, householders are
earning more ($45,000+) and spending more on housing ($230,000 for owners and $1,100-$1,400 for renters). Survey
results indicate that members of this market favor condominiums or high-rise apartments with two to three bedrooms
and two baths. They look for affordability, parking garages, windows/natural light and balconies/patios when choosing
housing.
Creative Professionals: Young adults employed in creative occupations (i.e., artists, designers, architects, media
workers) and knowledge workers (i.e., doctors, lawyers, scientists) form a subset of the entry-/higher-level professional
markets. Drawn to lively, vital urban environments offering a variety of entertainment options, members of this market
are potential buyers/renters of both traditional housing and larger adaptable live/work space in downtown Iowa City.
Students: University of Iowa students currently occupy the majority of rental housing in downtown Iowa City and will
remain an important market as development continues. Young (age 18-25) with incomes typically below $25,000,
these households will rent units priced between $700 and $1,200, depending on household size (i.e., presence/number
of roommates). Survey respondents age 19-24 showed the greatest interest in living in downtown Iowa City when
compared to other age groups. The vast majority (approximately 80%) preferred to rent and 2-bedroom, 2- bath high-
rise apartments or condominiums were the most desired housing types. Affordability, parking, security systems and
washer and dryers were selected by respondents as key features when looking for housing.
Housing Demand Opportunities
One of the best indicators of increasing housing demand is the presence of other local projects.
As is the case with most types of development, neighborhood momentum builds once there is a
critical mass of housing, and thus while nearby residential development is a sign of potential
competition, it is an even better indicator of potential opportunities. The handful of proposed
mixed-used developments indicates growing demand in the northern portion of the study area.
These developments include high-quality, amenity-rich housing with appropriate ground-floor
commercial space, ideal housing (and commercial activity) suited for development throughout
the district. As these developments gain momentum, they will upgrade the physical character of
the neighborhood, stimulate demand for surrounding uses, and increase pedestrian activity,
which will improve the neighborhood ‘feel’ in the district33.
Lastly, when considering housing demand, it is important to take into account the implications
that increased demand can have on housing affordability. According to the Iowa City Metro Area
Affordable Housing Market Analysis conducted in 2007, housing price increases have outpaced
income gain making Iowa City housing increasing unaffordable to the city’s residents. This is
particularly an issue as Iowa City tries to attract and retain a diverse population of the region’s
workforce. Affordable housing availability is compromised by escalating demand for market rate
housing. However, density is one way to increase the housing stock and support mixed income
housing development34. The Riverfront Crossings District is an ideal location to develop this
type of higher-density, mixed-income housing, in part because it is an area in transition, but
32 Ibid 33 Market and Financial Analysis for a Mixed-Use Development at 434 S. Linn Street, 2009
34 Iowa City Metro Area Affordable Housing Market Analysis, Mullin & Longergan Associates, December 2007
more importantly, because high-density TOD offers characteristics that are particularly relevant
to lower income households, such as transit accessibility and a broader mix of housing
size/styles. Many regions across the country have successfully instituted inclusionary housing
stipulations in new high-density housing development. Inclusionary housing policy would be a
win-win for the district, as it would ensure the development of affordable, workforce housing
and, because density bonuses and streamlined permitting are often used as incentives for
inclusionary set-asides, it could lead to fast-tracked, high-density development.
Mixed-use/Commercial Demand
Socioeconomic trends discussed in the first section of this summary indicate that Iowa City and
its surrounding metro region continue to grow, attracting highly-educated professionals.
Population and median income have continued to rise, indicating an expanding consumer
market. As noted in the last section, Iowa City continues to draw permanent residents,
particularly in the downtown area, with increased spending potential and desire to work, shop
and live in close proximity. The growth of this local and regional market provides great
opportunities for commercial activity in the district.
Commercial Supply
Existing regional commercial development falls into two main categories, mall and strip-mall
development and downtown mixed-use retail, services and entertainment. The latter is the type
of commercial activity proposed for the district. However, it is important to acknowledge that the
former exists, and to be successful, district development must be unique, authentic and
distinguishable from the existing shopping plazas and free-standing retail stores and restaurants
that line Highway 6 and 1. Downtown commercial development is comprised mainly of ground-
floor, mixed-use-style construction. Retail and restaurants make up the majority of downtown
commercial space (435,490 square feet), in addition to roughly 175,000 square feet of office,
municipal, civic and religious uses as well as vacant space. Restaurants and bars are the most
common commercial use, comprising roughly 45% of the space, followed by retail (28%) and
personal services (17%). The vacancy rate in downtown is 3.8%35.
There is currently one main commercial node in the district known as South Gilbert Street,
located south of the rail tracks, along South Gilbert Street. South Gilbert currently contains a mix
of intensive commercial uses, industrial uses, and a number of retail, office, and business
service establishments, but, according to the Central District Plan, it lacks aesthetic appeal with
typical strip-mall development of parking lots located at the front of the lots and buildings set
back from the street. This type of development is not conducive to pedestrian clientele or higher
density, mixed-use. It was cited in the Central District Plan that property owners and businesses
were interested in a more attractive and pedestrian-friendly streetscape as well as a welcoming
commercial identity to attract nearby residents and shoppers36. Stakeholders who attended the
community workshops identified Gilbert Street, second to Burlington, as good choice for
streetscape improvements37.
Commercial Demand
There are three main demand sources of mixed-use commercial development that will be
discussed in this section, regional demand, very-local demand and visitor demand.
The Riverfront Crossings district can expect to capture demand from the broader Iowa City and
regional market. The district is particularly well placed geographically, as it serves as an

37 Riverfront Crossings Workshop Audience Poll, November 13, 2009
important entryway to Iowa City’s Downtown. Three arterial streets — Kirkwood Avenue, Benton
Street and South Gilbert Street — converge in the area and serve as major travel corridors
between downtown Iowa City and Highway 6. Business and property owners have cited high
visibility along Gilbert Street and Kirkwood Avenue as an impetus to the creation of local retail.
According to the Central District Plan, some commercial property owners along Kirkwood
Avenue have expressed interest in developing residential units above storefronts to help
support the commercial area and to provide a better transition between the commercial zone
and the residential neighborhood to the east38.
Estimating the dollar amount of commercial demand is not an exact science as the consumer
marketplace is in constant flux, even when local demand exists and goods are available,
consumers often purchase non-local goods, particularly with the increase in internet shopping.
That said, it is possible to estimate the magnitude of current demand based on residential
demographic trends. This analysis, prepared by Marketek using ESRI Business Information
Solutions, applies expenditure potential by type of merchandise to market area population
figures in order to obtain potential sales demand. Potential sales are categorized into five
merchandise and service categories: shopper’s goods, convenience goods, food and
beverages, personal services and other retail expenditures. The table below estimates current
and potential demand generated by the local Iowa City market. The analysis indicates that
currently local area residents have the potential to support 2.44 million square feet of retail
space, with a projected net gain of 324,000 by 201739.

Further analysis estimated the potential retail sales for the greater regional market area through
2017. The regional market had the potential to support approximately 4.56 million square feet of
retail space in 2007. By 2017, an additional 794,000 square feet of retail space could be
supported by population increases in the greater market area41.

While it is clear that new development in the district could not capture even the majority of the
potential demand, it should plan accordingly and hope to capture some of it. According to
Marketek estimates, downtown Iowa City has the potential to capture roughly 25% of projected
local market expenditure increases and nearly 20% of projected regional market expenditure
increases through 2017. This translates into roughly 83,000 additional square feet of retail
space supported by local demand and roughly 150,000 additional square feet of retail space
supported by regional demand. While the district does not have all of the same competitive
advantages of downtown, it should be able to leverage its assets to capture a percentage of the
new demand42. Current demand for commercial space has not kept up with residential demand,
thus not all development in the Riverfront Crossings District should be required to be mixed-use.
As mentioned, the majority of the residential units are occupied in the recently completed
Telluride Building, however, the first floor commercial is vacant43. Workshop participants agreed
that while ground-floor retail should be prioritized, it should not be required, so as not to over-
saturate the nascent retail market in the district.
The focus of the proposed commercial development in the district is mixed-use retail and
service, however, many of the mixed-use developments proposed for the northern section of the
district, such as Hieronymus Square Tower and the proposed development at the St. Patrick’s
Church School site include flexible office space. It also should be noted that there is steady
demand growth for office space in downtown Iowa City. Marketek estimates that downtown has
the potential to attract approximately 353,000 square feet of additional office uses from 2007-
2017. Furthermore, their research indicates that there is a lack of large space leases (5,000
square feet or more) downtown, and a waiting market for small, for-sale spaces. Due to its
proximity to downtown, the Riverfront Crossings District might be able to capture some of the
downtown market, particularly if it is able to build more flexible space profiles44.
In addition to the regional and Iowa City demand that the district should compete for, there is the
very-local neighborhood demand that already exists, but is yet, untapped. Because of a number
of large municipal and institutional employers, the daily workforce population in the district is
significant. The University of Iowa’s auxiliary uses and county municipal buildings, to name only
two, provide a daytime population of employees as well as students who comprise a captive
market for neighborhood commercial activity. This population is expected to remain strong, and
42 Downtown Iowa City Market Niche Analysis, Iowa City, Iowa, Marketek, November 2007
43 Iowa City Planning Office
44 Downtown Iowa City Market Niche Analysis, Iowa City, Iowa, Marketek, November 2007
even expand as the University continues to develop its properties. This very local market should
be one of the main targets for district commercial activity.
Lastly, Iowa City has a strong regional visitor market. According to research conducted by the
Travel Industry Association of America (TIA) for the State of Iowa, shopping consistently tops
the list of activities for the state’s visitors, noted by 23% of visitors surveyed in 2005, followed by
dining (21.3%), entertainment (15.2%), touring (10%), and sports events (8.4%). Within Johnson
County, visitor spending has grown steadily from $193 million in 2000 to over $244 million in
2005, with an average annual increase of 5.3%. With its proximity to downtown and the
University of Iowa, the district is well positioned to attract Iowa City visitor spending.
Furthermore, a new performing arts center may be located adjacent to the Main University
Campus directly north of the project area. This arts center would almost certainly become a
visitor draw and allow the Riverfront Crossings District to capture some of the visitor spending45.
Commercial Demand Opportunities
In the long term, the many geographic and potential transit advantages of the district can be
leveraged to enable it to become a robust mixed-use neighborhood. If the proposed transit
stops are developed, TOD offering mixed-use commercial and housing will create a
neighborhood where residents can live and work, with easy and efficient access to downtown
Iowa City. One of the key advantages of mixed-use development is that, in combining housing
and commercial activity, it provides a ready market of residents who can support very local
demand. Once a critical mass of housing is accumulated, retail and services to serve this
community generally follow. This type of transit-friendly, mixed-use development will not only
appeal to the existent employment base and create a self-sustaining commercial district, but it
will become a key amenity to a residential market niche comprised of young professionals who
want to live in close proximity to their place of work. Increased residential demand from this new
population will further support commercial activity. Lastly, as the entire south side of Iowa City
experiences redevelopment and growth, the district, the land between the south district and
downtown will receive increased traffic and greater retail and commercial demand. This too will
lead to an increase in the importance of this corridor as an entryway into Iowa City.
According to stakeholders who participated in the November workshop, there is currently a
perceived lack of scarcity for commercial space. Similar to housing development, commercial
activity often begets further activity, so the proposals for various mixed-use buildings in the
northern portion of the study area are a strong indicator of future district growth and opportunity.
Despite current vacancies, every opportunity will look more attractive once momentum builds.
As commercial sites begin to run out, interest will skyrocket46.
In many ways the proposed developments along the northern boarder of the district are ideal
‘igniters’ to stimulate similar development continuing southward. Sites in the northern portion of
the district have the particular advantage of being in close proximity to downtown and the
existing college-residential market, which provides an existing customer base47. These sites will
appeal to retail, office, and residential tenants that wish to be located near downtown
employment centers, entertainment venues and cultural amenities, however, for price or space
reasons might prefer to locate in the district.

Conclusion
The Riverfront Crossings District has the potential to market itself as the up-and-coming TOD
neighborhood in Iowa City. With this goal in mind, there are a few key land use and
development principles that Iowa City should consider as it redevelops the Riverfront Crossings
District.
• Limit development in the 100-year flood plain: This limitation not only reduces the risk of
future infrastructure flooding, but also supports the creation of a riverfront district with
open space amenities.
• Support the creation of diverse open spaces: Iowa City should leverage the opportunity
to create a series of open space venues, including park land, athletic fields, green trails
and community gardens to add neighborhood amenities to the Riverfront Crossings
District.
• Connect with neighboring districts: As the Riverfront Crossings District develops into a
destination in its own right, it is important that it integrate with adjacent neighborhoods to
allow for pedestrian activity to flow freely. Workshop participants agreed that adding
streetscape improvements to Burlington Street would reduce the barrier between the
district and downtown Iowa City.
• Create residential development that attracts the creative class of young professionals:
To attract the key residential market demographic, young professionals, the district
needs to develop mixed-use, mixed-income housing options, which include a range of
amenities.
• Use residential demand to drive commercial demand: While it appears that residential
units are being absorbed faster than commercial space, the district can leverage its high
residential occupancy rates to create a captive market for local commercial activity by
creating and leasing commercial space that caters to its residential population.
• Leverage transit opportunities to create TOD: Just because transit access is available in
the district does not mean that true TOD will be created. Iowa City needs to ensure that
the land uses and density patterns in the district foster TOD. Strong support for TOD
was voiced by stakeholders at the November workshop, indicating that the community
favors a denser, mixed-use environment where they can live, work and play.
As mentioned previously, Iowa City has fared better than other U.S. cities throughout the recent
real estate turmoil. Iowa City’s real estate market has remained strong and the city has been
successful at attracting and keeping the creative class, in part due to the University of Iowa and
the regional Technology District. The Riverfront Crossings District should leverage this existing
regional advantage and its own local advantages, such as transit accessibility, proximity to large
employers (downtown and the University) and a unique opportunity to redevelop the
neighborhood fabric, to create a high-density, transit-oriented, mixed-use, mixed-income district
that offers housing and retail opportunities to the current and future residents of Iowa City.
