MEMORANDUM
Date: September 23, 2005
To: City Council and Planning and Zoning Commission
From: Robert Miklo, Senior Planner
Re: Zoning Code Work Sessions
On Monday September 26 and Tuesday September 27 at 6:30 P.M., the Planning and
Zoning Commission and City Council will meet to review the proposed zoning code. To
facilitate the discussion we will follow the matrix that the Commission used to review
requested amendments to the~ublic Review Draft (copies of the matrix were provided to
the Council on September 19).'~¢ We have also enclosed a memorandum regarding the
benefit/cost data for alley construction and a response to the Land Development Council's
statements regarding the proposed code.
Cc City Manager
Karin Franklin
The fo/lowing information about the proposed Zoning Code is being widely disseminated
by the Land Development Council. We have provided responses to clarify and address
the issues they have raised.
· How will this code affect future homeowners?
Land Development Council: The design mandates affect not only how the homes look,
but are intended to influence how people live. Often referred to as "New Urbanism",
these design standards are meant to determine how people live by controlling the design
of their homes. The smaller the lot (and hence, more affordable) the more limited back
yard living space will become by having the garage and possibly the driveway placed in
that space instead of patios, gardens and children's play areas. Alley(s) greatly reduce
the privacy of the back yard space. In most situations Homeowners Associations will
have to be established to provide a mechanism to provide general maintenance for the
alleys.
Response: We have heard over and over again from citizens that they desire attractive,
walkable, and safe neighborhood streets. Such streets are easy to achieve in larger lot
neighborhoods. The good news is that safe, walkable neighborhood streets are also
possible in small lot neighborhoods, if a few simple rules are fo/lowed. The intent of the
changes in the proposed code for Single Family Zones is to allow more opportunities to
develop neighborhoods with smaller, more affordable home lots. In the current RS-5
Zone, the minimum lot size is 8000 square feet; the minimum lot width is 60 feet. In the
proposed Code, the minimum lot size remains 8000 square feet and the minimum lot
width is increased to 70 feet. However, the minimum lot width may be reduced to 60
feet if garages are located flush with or set back from the front of the home and take up
no more than 50% of the front facade. In addition, the proposed code allows lot size to
be reduced to 6, 000 square feet and lot width to be reduced to 50 feet if garages are
located on a rear alley. This would be a similar subdivision design to many existing Iowa
City neighborhoods. There are literally hundreds of house plans that have both attached
and detached garages that will fit on lots of this size. There are many production
homebuilders across the country that have developed home plans that fit on these
narrower lots that have all the modern amenities expected by home buyers (attached
garages, wa/k-out basements, large family rooms, decks, patios, private rear yards).
Adopting these changes will allow greater flexibility than surrounding communities. For
comparison, in Coralville's equivalent single family zone (R1), the minimum lot width is
80 feet.
Alleys are not required by the ordinance; they are permitted as an option for those
wishing very narrow lots, not currently a/lowed in Iowa City except through a planned
development rezoning. If developments are built with lots less than 45 feet wide without
alleys, most of the front yard would be paved and there would little room for the
residential aspects of the home, front yards, street trees, and little space along the street
for visitors to park. In the few instances where such development has been a/lowed in
Iowa City without an alley, po/ice and enforcement officials regularly receive complaints
from home owners about driveways and mai/boxes being blocked by cars being parked
illegally.
· But I already own a home, why should I care?
Land Development Council: You may be the exception to the rule, but most people
change residences numerous times as their income, families and age change. If and
when you decide to change, your choices could be limited.
Response: To the contrary, the new standards in the Code should allow a wider variety
of options in Iowa City and certainly a wider variety of options than in surrounding towns.
However, it is the developer/builder that decides what choices to offer. It is typical for a
production home builder to limit consumer choices to only a smafl number of house
plans. Given that there are only a few production homebuilders doing business in Iowa
City and surrounding communities, there are currently a very limited number of house
styles and types to choose from in the moderate price range (homes <$220, 000). In
addition, subdivisions with larger lots (typical lot width in Iowa City over the last 10 years
is over 80 feet), there are often private covenants and restrictions that limit homeowner
choices and drive up the cost of housing, effectively excluding those with limited
incomes. These private covenants include minimum house size requirements,
requirements for 3-stall garages, prohibitions on duplexes, accessory apartments, and
manufactured homes.
In the proposed code, there is only one new standard that applies to single family homes
and it only applies to lots narrower than 70 feet. This standard states that garages must
be located flush with or set back from the front facade of the home and must take up no
more than 50 percent of the length of the front facade. While some current house plans
may have to be adjusted to meet these standards, there are literally hundreds of house
plans that have front-loaded, attached garages that meet the standard. In addition, there
are hundreds of house plans that have rear-loaded, side-loaded, or recessed garages
that could be developed on even smaller lots not currently allowed by our zoning code.
The proposed code will open up new opportunities for a variety of home plans not
currently offered by homebuilders. There are many home plans that have front-loaded
and rear-loaded garages that offer afl the private amenities desired by home buyers, but
do so in a manner that ensures that neighborhoods will be pedestrian-friendly with room
for sidewalks, street trees, a front yard and residential aspects of the home that face the
public street.
Will this make housing in Iowa City more affordable?
Land Development Council: No. Unfortunately, the proposed code will actually make
housing in Iowa City, an already expensive place to live, even less affordable for the
average working family. Because of mandates on how homes should look on smaller
lots, developers will be less likely to build more affordable housing. The costs to
construct smaller homes will increase due to design mandates. Additionally, the
mandatory alley provisions for smaller lots will make the smaller lots more expensive
themselves. Homeowners association fees for alley snow removal and maintenance will
be an additional cost not always associated with home ownership.
Response: There is no statistical evidence submitted by the Land Development Council
to support the statement that housing would be less affordable for the average working
family if these standards are adopted. As mentioned previously, the new code allows
development of single homes on lots smaller and narrower than what is currently
allowed. For these smaller lots, there is only one new standard regarding placement of
the garage. There are no standards that dictate style or design of the home and the new
standard certainly does not prevent private rear yards, walk-out basements, or any other
modern amenity desired by home buyers.
A/lowing homes on smaller, narrower lots should substantially reduce the costs of
development, even if a rear alley is used. When lot sizes and widths are reduced, not
only are there savings in land cost, but it costs less per dwelling to extend water, sewer
other utilities, and street pavement. The additional cost per unit for alley pavement is
more than offset by savings in land cost, street pavement, water, sewer, and other
utilities. In addition, the developer reaps of the benefit of getting to sell more home lots
per acre of land.
· What are residential design standards?
Land Development Council: Residential design standards are laws that specify exactly
how a home should or should not look. They can range from requirements on garages,
window trim, doorways and a host of other home features. They can be implemented
either by mandate, such as the proposed Iowa City code, or they can be made optional.
Response: There are n.._qo such design standards for single family homes in the proposed
zoning code, other than placement of the garage on lots narrower than 70 feet.
Development of townhouses is not feasible under the current zoning regulations without
going through a planned development rezoning process. In addition, a rezoning to a
higher density zone is often necessary to develop duplexes.
In the new Code there are new allowances for duplexes on comer lots in the RS-5 Zone,
the most prevalent zoning district in the City and dimensional standards have been
adjusted to allow townhouse development by right without the need for a planned
development rezoning. With these new allowances, some basic standards have been
added to the Code to ensure that these larger, bulkier buildings will fit into
neighborhoods with a mix of housing. These standards are similar to the conditions
often applied dudng the planned development process. The standards address garage
placement, ensure that pedestrian entrances face the street, and require trim around
windows and doorways to prevent large blank facades on these larger buildings. When
there are four or more townhouse units attached, there is also a requirement that there
be some variation in setback or facade between the attached units to prevent
monotonous streetscapes. These are not expensive or onerous requirements and are
what has typically been required and built in townhouse and duplex developments in
Iowa City.
For apartment buildings, the current zoning code contains standards that apply in the
Central Planning District, which ensure that these larger bulkier buildings fit into
neighborhoods that have a mix of housing types. These have been in the code for about
five years and have been working well. In the proposed code, some of the basic
standards are applied citywide to afl new apartment buildings.
· Why does the Land Development Council oppose design mandates on homes?
Land Development Council: Fundamentally, we believe a person has the right to
determine how they want to live and how they want their homes to appear. We believe
this is an inherent property right citizens enjoy. Furthermore, the LDC believes it is
wrong for local government to legislate what they judge to be appropriate life styles and
aesthetically pleasing design in place of the property owners' choices. Trends and
consumer preferences are constantly changing. The law should allow for that natural
change - not resist it.
Response: The Planning and Zoning Commission agrees that the City should not be
dictating the design of homes. Again, the proposed Zoning Code does not dictate home
style or design. It does provide a wider variety of higher density, affordable home
options than currently allowed in Iowa City or in surrounding communities. The Planning
and Zoning Commission does believe that the City has a role in ensuring that
neighborhoods are built with functional, safe, and attractive public spaces along
neighborhood streets. Citizens have repeatedly confirmed this desire and expectation.
· Is it normal for a City to mandate housing designs?
Land Development Council: While some cities have codes on residential designs, many
are only optional as part of a broader package of incentives or as part of a specifically
identified area with specific architectural history or importance. It is rare to find sweeping
design mandates on all residential housing.
Response: See above.
· Does the location of a garage really make a difference?
Land Development Council: Yes. As with most housing design, the placement of the
garage can fundamentally affect the structural design of the entire home. With the
current proposals in the development code, many popular housing designs will now be
literally i/legal.
Response: The location of the garage can have a significant effect on the quality of our
neighborhoods, particularly in neighborhoods with small, narrow home lots. Some of the
best information and research on these affects are available from the National Home
Builder's Association. That is why some of the nation's largest production home
builders, those that are building the more affordable homes on smaller lots, have
developed numerous house designs that incorporate all the modern features desired by
home buyers and also respect and enhance the public streetscape. Alternative home
designs, very similar in every way to the popular designs mentioned by the Land
Development Council are currently available from other production homebuilders in the
Midwest. These are no more costly to build and have the added benefit of ensuring that
new small lot neighborhoods have the same public street amenities enjoyed by
neighborhoods with larger lots.
· What impact will requiring alleys have on the cost of a home?
Land Development Council: While the design standards will allow narrower street
pavement in front of lots with alleys, there will still be more square yards of pavement
required in the development of the subdivisions. Additionally, if the garage is not
detached from the house and placed adjacent to the alley, there will be a significant
portion of the back yard covered with pavement thus rendering it marginally useful for
private passive or active recreational space.
Response: The proposed zoning code does not require alleys. However, developers can
take advantage of the bonus density provisions and build on lots smaller and narrower
that what is currently allowed. Reducing lot sizes results in cost savings on land, street
paving, and the extension of utilities, so that on a per lot basis, homes will be less costly.
For the narrowest home lots, these savings more than offset the cost of bu#ding rear
alleys and the developer also reaps the benefit of getting to sell more home lots per acre
than what would otherwise be allowed.
· What i~ I can't afford a home on a larger lot but don't want to live on an alley?
Land Development Council: The code mandates that alleys be installed on any
developments with lots 45 foot or less in width. So the most affordable entry level homes
will be required to have alleys. Not to mention their garages must be located in the rear
of the house.
Response: The City currently does not allow single family home lots that are less than
45 feet wide (nor does Coralville). In fact, many communities avoid these issues entirely
by establishing large minimum lot sizes. Requiring minimum lot sizes of 10,000+ square
feet with minimum 100 foot frontages is not an uncommon practice. Duncan Associates
confirmed that Iowa City allows smaller lot sizes than many communities. Continuing this
progressive trend toward encouraging compact affordable neighborhoods, the proposed
zoning code will allow single family homes on lots as narrow as 30 feet wide. Given that
each side yard must be at least 5 feet wide to ensure separation from the neighboring
house, homes on these lots will be 20 feet or narrower in width. Given that a typical 2-
car garage is 20+ feet wide, it is not possible to fit both the house and a front-loaded
garage on such a narrow lot, without serious consequences for the public street
frontage. There will literally be no room for a front door, a front yard, a public sidewalk, or
street trees. The entire frontage along a street built with such homes would be paved.
Rather than disallowing such narrow lot development as many communities have done,
the Commission is recommending new allowances for narrow lot development, provided
that certain minimum standards are met to ensure that the public spaces along
neighborhood streets are not compromised.
· Will the City at least be responsible for the maintenance and upkeep of the alley?
Land Development Council: No. The proposed code only says the City will be
responsible for the "useful life" of the pavement. After that undefined period expires, the
property owners will be responsible for repairs and maintenance and assessed property
taxes accordingly. Snow removal, general maintenance and cleaning will be the
responsibility of the homeowner or homeowners association.
Response: It has always been the case that property owners have to share in the cost of
City services and infrastructure. If, however, more compact neighborhoods are built,
there will be less infrastructure needed per household. If a home buyer chooses to buy
a home with a rear alley, they will have to share in the cost of upkeep, just as they have
to share in the cost of maintaining the streets and sidewalks in front of their homes.
Each homeowner's share of public infrastructure costs is dependent on the size of their
home lot. For those with larger lots, their share is larger, since it costs more to extend
streets, utilities, and sidewalks along their wider frontage. For those with narrower lots
that have alleys, they will spend less on costs for street pavement, utility extensions, and
sidewalks, which in most cases will more than offset the cost of alley pavement.

MEMORANDUM
Date: April 19, 2005
To: Plannin9 and Zonin§ Commission
From: Tokey Boswell, Plannin9 Intern
RE: Benefit/cost data for alley construction
At the request of the Plannin9 and Community Development Department, I have completed
a benefit/cost analysis that examines the effects of buildin§ alleys into new subdivisions.
Usin9 ~luidelines from the proposed zonin§ code, I have completed several development
comparisons for a theoretical parcel of land in Iowa City. The parcel size has been held
constant (550 by 240 feet, approximately one block) for accurate comparison. The
resultin9 block arrangements have differences in the number of parcels possible for any
9iven zone, based on the presence of alleys. The difference in the number of lots per block
translates into different costs for the provision of infrastructure. Future analyses that use
differently sized parcels will result in slightly different numbers, but the trends and overall
results will be the same.
I believe that two points of interest emer§ed from the analysis. The first is that buildin§
alleys into residential subdivisions, even on this fairly small scale of just one average block,
9reatly increases the number of lots possible on a 9iven parcel of land. The expanded
number of lots leads to reduced per-lot infrastructure costs, even though §ross expenses
increase by the cost of alley construction. Lower per-lot infrastructure costs benefit
homebuyers because the overall cost of housin9 is lower. Alley costs are therefore not
prohibitive for homebuyers. Alley costs, on a per-lot basis, are not prohibitive to developers
either, because the potential financial 9ains from the 9rearer number of lots permitted make
the investment profitable for a developer in every example. In this example, it costs
approximately $25,000 to build an alley into the subdivision, and developers are awarded
between six and sixteen additional lots for doin9 so.
The second point of interest is the relationship amon§ alley provision, lot size, and the
amount of pavin9 per lot. In my examples of alley construction for the RS-5 and RS-12
zones, buildin9 alleys into the block decreases the amount of pavin9 per lot - more people
are served by the same amount of cement. (The same point can be made for other
elements of infrastructure - in blocks with alleys and smaller lots, more people are served
by the same amount of water pipe, TV cable, etc). In the RS-8 example, pavin9 per lot
increases slightly with alley construction, due to the relatively small difference in lot widths
permitted with and without alleys in this zone - the difference is larger in the RS-5 and RS-
12 zones. Servin9 more people with the same amount of infrastructure is a positive
measure of efficiency in service provision, and a powerful tool to prevent urban sprawl.
The table below hi§blights the most important financial aspects of constructin§ alleys. If I
assumed a per-square foot lot sale value, I could calculate the 9ross return expected for
developments with and without alleys. I was hesitant to do so, however, as the numbers
will vary based on other features of the lot and home. At almost any sale price, the number
of lots is more significant in determinin9 the profitability of development than the costs of
alley provision, on this and larger scales. This is because the cost of buildin9 an alley dust
over $25,000 in this example) will usually be recouped by sellin9 only one additional lot.

To complete the analysis, I had to make several assumptions about street, alley, water, and
sewer infrastructure costs. I used the best available data for each category, and
documented the assumptions in the attached spreadsheets. It is most important to note
that I held my assumptions steady for all comparisons. The only variations are in the
provision of alleys and the lot sizes permitted under each zoning designation.
In summary, I find that:
1. The alley provisions contained in the proposed zoning code have the potential to
decrease the cost of housing in Iowa City (due to lower per-lot infrastructure costs
associated with smaller lots).
2. Building alleys into new subdivisions has a positive financial effect for developers (due
to the increased number of units possible on a given parcel).
3. Encouraging smaller residential lots through the provision of alleys has the potential to
increase the City's service efficiency and to reduce urban sprawl by serving a greater
number of citizens with equivalent investments.

Excel workbook with comparisons

Notes on the alley analysis:
1) "Infrastructure costs" include costs for street construction, alley construction, water line
extension, and sewer line extension, as documented in the excel workbook. Estimates for the
first two were obtained from the Engineering department, and used the same price per square
yard. Estimates for the latter two were obtained from an MMS employee, and were based on
averages for several new residential projects. Gas lines, electricity lines, and cable TV
extension were not calculated into the costs, as they are usually provided free of charge to the
developer. Sidewalks and driveways were not calculated - sidewalks will lower per-lot prices for
developments with alleys (same gross price, more units), but driveways will depend upon
arrangement.
These are the best numbers we have, and should not be subject to debate. Even if these
numbers are off significantly, though, the results are the same - more lots equals smaller per-lot
costs at any infrastructure price.
2) Some claim that subdivisions with alleys are less attractive and sell for less than do conventional
developments. I could not find good data to prove or disprove this idea; there are simply too
many variables in determining home prices. In this analysis, the value between with and without
could change drastically and it would still be beneficial to provide alleys.
For example, in the RS-5 zone: gross revenue from selling 14 lots at $40,000 is $560,000, and
for selling 20 lots at $30,000 each it is $600,000. The cost of the alley ($25,000) is the only
difference in gross costs. Therefore, at this level, even a 25% reduction in sale price is still
profitable to build in alleys. For the RS-12 zone this is true to a much greater extent (up to 40%,
eg. 20 lots at $20K=$400K and 36 lots at $12K=$432K), because the bonus in number of lots is
so significant.
This comparison must be' done with lots, not with homes. Once you start factoring in costs for
construction it gets confusing and there are simply too many variables. Instead, assume that
developers will understand how to build the structures in order to make the profit they want on
each unit regardless of lot size or arrangement.
3) The difference in paving infrastructure costs per lot in the RS-8 zones is due to two phenomena.
First, the difference between lot size permitted with and without alleys in this zone is smaller
than those in other zones:
RS-8: without 55, with 40, difference =15, relative difference = 15/55 = 27%
RS-5: without 70, with 50, difference=20, relative difference = 20/70 = 29%
RS-12: without 55, with 30, difference =25, relative difference = 25/55 = 45%
Second, this example allows for an exact hit on the 55' lots and not on the 40' lots. A more
contrived example could have reversed the trend slightly (but would have been ingenuine). In all
cases, though, the difference here will be less than the other zones.
4) A note on average parcel sizes: this sample tract has some sizes that fit better than others, and
that will be the case for all examples. Nevertheless, it is easier to divide a large tract into smaller
units than larger units - that is, it's easier to divide a foot into two-inch long segments than into
five-inch long segments. There will almost always be less "waste" or unused space with smaller
lot sizes. On large tracts, using alleys allows developers to get ever closer to the absolute
minimum lot size.

On larger lots, this is not as much of a concern because there is more

in the last 10 years in Iowa City were built with lots greater than 70 feet

know what the underlying standards are before they can be modified or varied. Subsection

underlying zoning requirements. In addition, there is also an overarching "exceptions"
section that allows modifications to the approval criteria (See 14-3A-7 on p. 115).
Unlike the current ordinance, the provisions of Article 14-3A state clearly what standards are

should become more prevalent in these zones. According to
the Housing and Inspection Services Department all.of the new
12-plexes being built around town have accessible apartments
on the first floor and most of these are two-bedroom units.
Due to the age of the housing stock near downtown, there are
apartments that do not have accessible units. However, given
that many of these properties also contain more apartment units
than would be allowed today under the current zoning, it woUld

Given the complexity of designing and implementing an

Commission concurred that such an effort should be considered
separately from the zoning code rewrite project. In addition, the
City has convened a Scattered Site Housing Taskforce that has

not support the amendment proposed
Requestor: Larry Svobada The reason that there is a break given on the parking in the by Mr. Svobada.
PRM Zone in the current zoning code is that this zone is
intended for areas close to downtown and the University.
When the PRM Zone was established, the City predicted
that fewer parking spaces would need to be provided,
because some tenants would choose not to own a car when
living close to campus and downtown commercial services.
However, the demand for parking was higher than
anticipated for these properties despite their proximity to
campus and downtown, resulting in spillover parking onto
nearby neighborhood streets. This is particularly true for 4
and 5-bedroom apartments. In effect, this allowed more
people to live on a property with fewer parking spaces
required. In the proposed Code, therefore, the parking
requirement is increased to 3 parking spaces for each 4 and
5-bedroom apartment in the PRM Zone. The parking
requirement for 2-bedroom apartments is actually decreased
to I parking space for each unit.
These changes in the parking requirements should
encourage the development of apartments with smaller
numbers of bedrooms on properties that have limited space
for off-street parking. 4 and 5 bedroom units would still be
allowed, but will likely occur on larger properties that have
space for the off-street parking that is needed for these
larger units. The overall effect will likely lessen the impact of
spillover parking onto surrounding streets.
