Historic Review for HPC24-0026: 410-412 North Clinton Street
General Information:
Applicant/Owner: Jeff Clark jeffmc1973@yahoo.com
Classification: Local Historic Landmark
Project Scope: Demolition of the historic garage and construction of a portion of
the neighboring multi-family unit across the rear portion of the
Landmark property as agreed in exchange for landmark
designation.

Property History:
The Cochrane-Sharpless-Dennis House was built in 1865 as a two-story brick Italianate
House with a low-sloped side-gabled roof. The house has a simple cornice supported
on paired brackets. The symmetrical façade includes a classically detailed center entry
wit narrow sidelights and transom. The first-floor façade has 4-over-6 double hung
windows extending floor to ceiling. The second-floor windows have heavy stone sills
and lintels. The central windows are similar to the first-floor windows and the ones on
each side are a smaller 4-over-4. The house had a small two-story addition by 1899. A
two-story apartment building was built behind the historic house in 1969.
A 2017-2018 landmarking attempt failed due to owner objection. Then the property was
sold to the current owner. Discussions with the owner regarding a landmark designation
tied to a development proposal first came to the Commission in January 2020. In July
2020 the proposal was revisited and both HPC and Friends of Historic Preservation
provided comments and generally supported the basic proposal. The Commission held
the public hearing for landmark designation in December 2020 and the property was
designated by Council in January 2021. In 2023 Staff approved repairs to the front
porch. In March 2024, the Commission approved the rehabilitation plan for the
landmarked house. Recently, the development project has been proceeding through a
design review process and has reached a point where the portion that impacts the
landmark property is ready for review by the Commission.
Detailed Project Description:
This project demolishes the houses at 400 North Clinton Street and 112 East Davenport
Street (which are outside the Commission’s purview) and constructs a 5 story multi-
family structure in their place. As part of the development and landmarking agreement,
a three-story portion of the building and the basement garage entrance extend across
the rear portion of the landmark property to the alley. The demolition of the garage on
the landmark property will also be a part of the project. The Commission’s purview
extends to the review of the garage demolition and the portion of the new construction
on the landmark property.
The portion of the project under review includes a three-story flat roofed, brick wing of
the new development. The lower, base of the building is a darker brick that will match
the historic building. The upper floors are a lighter color that will be compatible to the
historic building. The new construction will have stone coping at the roof edge, a stone
band at the transition between brick colors, stone sills and brick lintels. The windows are
rectangular double hung windows hung individually or in pairs. Areas between windows
(vertically) will be accented with recessed brick panels. Balconies for second and third
floor apartments extend north from the building toward the alley.
Guidelines:
Section 4.1 Balustrades and Handrails recommends:
• Installing turned balusters in balustrades that have an actual diameter of 2 inches
or greater, or square spindles that are 1-1/2 inches or greater in width.
• Installing top and foot rails that are at least 2 inches in thickness.
Section 6.1 New Primary Structures recommends:
• Following the guidelines for new balustrades and handrails in section 4.1
Balustrades and Handrails.
• Using siding that is consistent with the architectural style of the new building.
Most historic siding in Iowa City is wood. Fiber cement siding with a smooth finish
is an acceptable substitute for wood siding in most circumstances.
Section 7.1 Demolition of Whole Structures or Significant Features recommends:
• Retaining historic garages. If the period garage is insufficient for modern-day
vehicles, efforts should be made to construct a new garage on another portion of
the site.
Section 9.0 Design Guidelines for Multi-Family Buildings, Section 9.1 Site Elements
recommends:
• All exterior lighting, including balcony and porch lighting, must be carefully
placed, downcast and shielded so that entrances, sidewalks and stairways are
well lit, but the lighting is non-obtrusive to neighboring properties.
• No exterior light source should be located on poles more than 15 feet high. When
lights mounted on buildings are intended to provide site lighting rather than
corridor or exit lighting, they must be mounted no higher than 15 feet.
• Parking lots, including detached garages and carports, must not be located
between the principle building and the street. Parking must be located behind a
building, below grade, or under a building.
• Where parking is located below a building, any exposed portions of the exterior
walls of the parking area visible from a street must appear to be a component of
the facade of the building. The use of similar building materials, window
openings, and providing facade detailing similar to the upper levels are examples
of how this can be achieved. In no case shall a building have the appearance
from the street of being elevated above a parking level, or “on stilts.”
Section 9.2 Architectural Elements recommends:
• The building should include architectural details to add interest to building
elevations visible from the public street, including but not limited to the following:
Quoins, dentils, cornice moldings, brackets, arches, corner boards, keystones,
decorative lintels and sills, double-hung windows, soldier courses, belt courses,
bay windows, and other decorative features as appropriate for the design of the
overall building and materials being used.
• The purpose of requiring an architectural style is to ensure that the mass, roof
form, window style and configuration, and the basic architectural details of a
building are generally compatible with the historic character of the historic or
conservation district. New buildings should appear similar to a large house or a
small historic apartment building.
• Any building elevation that is within public view (visible from a public street,
public sidewalk, public access easement, or other public way, or from a public
park or other public open space area.), must be designed in a manner that is
consistent with a historic architectural style typical of residential buildings in the
historic and conservation districts. However, building facades that are visible only
from public alleys are not subject to these standards.
• Balconies, decks, exterior stairways, corridors, lifts and ramps should be
designed so that they are integrated into the overall design of the building.
Methods of integrating these elements into the building design may include, but
are not limited to, fully or partially recessing them into the facade of the building,
placing them under a roof that is integrated into the overall roof plan, utilizing
supports that are compatible with the rest of the building in terms of materials
and design, and utilizing supports that reach to the ground rather than append on
the exterior of the building.
• Balconies and exterior stairways, exterior corridors and exterior lifts must comply
with the following standards: The design of any balcony, exterior stairway,
exterior lift or exterior corridor must utilize columns, piers, supports, walls, and
railings that are designed and constructed of materials that are similar or
complementary to the design and materials used for the rest of the building.
• Rooflines should reflect the predominant roof type, orientation, scale and pitch of
existing buildings within the neighborhood.
• The placement of windows and doors on street elevations should be consistent
with the window and door patterns found on other properties in the surrounding
neighborhood, and of a similar size, scale and proportion to the windows of other
buildings in the neighborhood. Individual window units that are located in primary
living spaces, such as living rooms, dining areas, and bedrooms, must have a
height that is at least 1.5 times greater than the width of the window unit.
Section 10.0 Secretary of the Interior’s Standards for Rehabilitation recommends:
• 9. New additions, exterior alterations, or related new construction shall not
destroy historic materials that characterize the property. The new work shall be
differentiated from the old and shall be compatible with the massing, size, scale,
and architectural features to protect the historic integrity of the property and its
environment.
• 10. New additions and adjacent or related new construction shall be undertaken
in such a manner that if removed in the future, the essential form and integrity of
the historic property and its environment would be unimpaired.
Analysis:
The Cochrane-Sharpless-Dennis House was locally landmarked as part of an
agreement where the neighboring structures to the south would be demolished for the
construction of a multi-family building, a portion of which would extend north toward the
alley across the back of the landmarked property, necessitating the demolition of the
garage. During the initial discussions, the Commission and Friends of Historic
Preservation commented on the overall building design including number of stories and
roof configuration. Now, during this formal review, the Commission’s purview only
extends to the portion of the new construction located on the landmark property and the
garage demolition.
While this garage, is in good condition, likely built in the 1930s, it must be removed to
provide access to the underground parking that is included in the project. Staff
recommends approval of the garage demolition if the new construction is approved.
The proposal includes a brick structure that attempts to work with the historic brick
building. Staff had provided initial comments during earlier design phases including the
fact that this portion of the building did not include architectural details that would help it
to comply with the guidelines in section 9.2 that requires such details. The applicant
provided a statement (which is attached here) that indicates that this portion of the
building is meant to be a background building and the lack of ornamentation is
“purposefully simple so that it does not detract for the historic building and the buildings
are clearly distinguishable.” The addition of a brick wall adjacent to SE corner of the
historic building and extending south to the new construction will further obscure the
view of this portion of the new construction.
The north, alley side elevation of the building includes the garage doors at ground level
and below , the stone band above that marking the change from the lower area of brick
to the upper, individual windows on each floor aligned vertically, and a balcony area.
The proposal indicates that the wall in the balcony area will be a different material that
has been indicated to be an aluminum siding. Staff recommends that this material is
revised to follow the guidelines. Staff had also commented on the balconies during the
early review since they were not integrated into the design but appended to the building
surface. The elevation drawings continue to show this configuration as does the third
floor plan. The second floor plan, however shows the balcony mostly, if not completely
recessed into the structure. Staff finds this to be acceptable and recommends that the
third floor balcony and the elevations are revised to show the balcony inset in order to
follow the guidelines.
The east elevation drawing most clearly shows the window patterning and other details
since that will be the most visible portion of the building. Staff notes that the elevation
shows first floor windows that are not shown on the plan drawing. Since the windows at
this level help the building comply with the guidelines for parking areas, staff
recommends that these windows are included in the approved project. Since the west
side is very near the existing apartment building, staff does not think first floor windows
are necessary there.
Staff Recommendation:
Staff recommends approval a Certificate of Appropriateness for the project at 410-412
North Clinton Street as presented in the staff report with the following conditions:
Plans are revised to include the first floor windows on the east elevation and to
inset the balconies as shown on the second floor plan.
Window and door product is submitted for review by staff
Aluminum siding is revised to a product that complies with the guidelines and is
reviewed by staff and Chair.

Project statement from owner and owner’s architect
This is a two- story historic property that has a non-historic addition of approximately the
same height on the east side. The addition also extends to the south where it is
partially visible from the street. The new structure for which a COA is requested, is
located behind both the addition and the historic building. It is two-stories in height and
only about 42 inches taller than the historic building. The view of the new building and
addition will be further obscured with the construction of a 6-foot tall masonry wall in
front of the addition. Thus, given the arrangement of all three structures on the site, the
new building will become a background building and be only partially visible from the
street. The historic building will be the most prominent building on the site.
The color of the new masonry fence and the new building base will match the historic
building. The upper portion of the new building will be a compatible lighter brick color
but of a similar hue. The massing and details are also designed to be purposefully
simple so that it does not detract from the historic building and the building are clearly
distinguishable. Color will be the unifying element of the composition.
Section 3.2. Exceptions to the Iowa City Guidelines allows for exceptions to the
guidelines in Uncommon Situations. The construction of a new building behind a
historic building and an inappropriate addition is an uncommon situation. This provision
also provides for use of the Secretary of the Interior’s Standards for Rehabilitation in
Section 3.3 Additional Historic Preservation Guidelines. SOI Standard #9 states: New
additions, exterior alterations, or related new construction will not destroy historic
materials, features, and spatial relationships that characterize the property. The new
work will be differentiated from the old and will be compatible with the historic materials,
features, size, scale and proportion, and massing to protect the integrity of the property
and its environment.
Staff Report July 9, 2024
Historic Review for HPC23-0070: 937 East Davenport Street
General Information:
Applicant/Owner: Marybeth Slonneger
Classification: Local Historic Landmark
Project Scope: Construct an addition on the back of the hous.
Applicable Regulations and Guidelines:
4.0 Iowa City Historic Preservation Guidelines for Alterations
4.3 Doors
4.5 Foundations
4.7 Mass and Rooflines
4.9 Paint and Color
4.11 Siding
4.12 Site and Landscaping
4.13 Windows
4.14 Wood
5.0 Guidelines for Additions
5.1 Expansion of Building Footprint
Property History:
The cottage at 937 East Davenport was built before 1874, as a side-gabled one-room cottage
with a loft above for the children to sleep. The front door is centered on the house and there is
a single window to the east of the door. A gable addition was added to the rear of the house
before 1882 and a second, smaller gabled addition was added prior to 1920. Also prior to 1920
an open porch was added to the EL created by the original portion of the house and the first
addition. The house has wood lap siding with corner boards, minimal flat casing surrounding
double-hung windows, and a brick chimney in the end of the first addition. This house has had
very few changes since 1920. At some point, rolled asphalt siding was installed, covering the
original wood. The asphalt siding was removed before 2012 and the roof, which was originally
wood shingle and likely replaced over time with metal, was also replaced by then with the
existing metal roof. The current owners extended the porch to the rear of the house, along the
side of the rear addition. New trim boards have been installed over the original trim which
remains underneath. This alteration could be reversed.
Detailed Project Description:
This project adds a room to the back of the house. That addition is set in an unknown amount,
presumed to be about 1 foot, on the east side and extends to a similar setback on the west
side, enclosing the southern end of the existing porch. The addition will be a single room with a
side-facing gable, similar to the oldest portion of the house closest to the street. The addition
will have wood siding and trim to match the historic house. The drawings mention enclosing
the existing open porches with screens but information about the framing, doors and other
details have not been submitted for review of that alteration. The addition will have one window
in each of the east and west walls. The south wall will have two windows and a centered door.
Guidelines:
Section 4.3 Doors recommends:
• Adding new door openings that are trimmed to match other doors and windows in the
building.
• Substituting a material in place of wood for doors and screen doors only if the substitute
material retains the style and appearance of the historic doors and screen doors. The
substitute material must be durable, accept paint, and be approved by the Historic
Preservation Commission.
Section 4.7 Mass and Rooflines recommends:
• Preserving the original roof pitches and spans.
• Preserving the original walls and vertical corners that define the massing of a historic
building.
Section 4.13 Windows recommends:
• Adding windows that match the type, size, sash width, trim, use of divided lights, and
overall appearance of the historic windows.
• Adding new windows in a location that is consistent with the window pattern of the
historic building or buildings of similar architectural style.
• If an opening is to be relocated, it should not detract from overall fenestration pattern.
• If an opening is to be closed on a framed structure, appropriate siding that matches the
existing should be used with its members being placed across and randomly extended
beyond the opening.
Section 4.14 Wood recommends:
• Substituting a material in place of wood only if the substitute material retains the
appearance and function of the original wood. The substitute material must be durable,
accept paint, and be approved by the Historic Preservation Commission.
Section 5.1 Expansion of the Building Footprint recommends:
• Distinguishing between the historic structure and the new addition. This may be
accomplished easily by offsetting the walls of the addition from the walls of the original
structure.
• Matching key horizontal “lines” on the existing building, such as water table, eave
height, window head height and band boards, in order to provide continuity between the
addition and the historic structure.
• Using a palette of materials that is similar to that used on the historic structure.
• Placing building additions at the rear of a property, if possible.
• Constructing an addition foundation that appears similar to the historic foundation.
• Constructing additions that are consistent with the massing and roofline of the historic
building. This requires that the wall areas and corners, as well as the roof pitches and
spans are all consistent with the existing building and have a proportion that is similar to
that of the existing building.
• Constructing the roof overhang, soffits and eaves of the addition so that they match the
roof overhang, soffits and eaves of the existing building. When the eaves of an addition
intersect the eaves of the existing building, care should be taken to assure that the two
eaves align properly. The trim details of a new eave should match the eave details of
the existing building.
• Applying siding to a new addition that appears similar in size, shape, texture, and
material to the existing siding on the historic building.
• Constructing additions with materials that appear similar to the historic siding, trim,
moldings and other details of the original building.
Analysis:
In Staff’s opinion, a small, simple, single room addition is most appropriate for this house. The
main concern is whether or not the addition can be located as shown on the drawings due to
site setback requirements. While the drawings show the house with a property line located
roughly 5 feet from the existing house, the Johnson County Property Information viewer shows
that the house is located at an angle in relationship to the property line (so the existing setback
changes along the length of the house) and is roughly 1 to 2 feet from the house. The new
addition may need to be revised to meet the zoning code requirements. Staff recommends that
the new addition is set in from the west edge of the existing porch, which aligns with the west
edge of the oldest (north) portion of the house. The drawings do currently show this.
The existing building includes three rooms built at different times with the existing south room
having a different eave height than the earlier portions of the house. Since the new addition will
attach to the south room, staff recommends that the new addition matches this addition in
regard to the requirements of the guidelines.
The drawings appear to show that the new addition will match the roof slope, eave condition
and eave height of the rear addition to which it is attached. The addition will be constructed on
a slab on grade. Staff recommends that the floor height of the existing house is matched in the
new addition. Since this house is not raised above a tall basement, it sits close to grade,
setting the house on a slab could be considered appropriate if the floor elevation is maintained
and the addition is not a step down. It is likely that the proposed new door will need a landing
and two or more steps down to grade. It is also likely that this door will need to be 6’-6” tall to
meet code requirements. Staff recommends that this door is a wood or fiberglass half-lite door
with two or three panels below.
The project says that the new addition will have a standing seam metal roof. This type of roof
is approvable but the approvable roof would not match the existing agricultural metal roof on
the house. Staff recommends that the new addition either has a flat panel standing seam metal
roof or asphalt shingles which are both approvable. The historic house originally had wood
shingles which were covered in a flat panel standing seam roof historically.
Staff Recommendation:
Staff recommends approval a Certificate of Appropriateness for the project at 937 East
Davenport Street as presented in the application with the following conditions:
Window, door, and roofing product information is submitted for review by staff.
The eave and floor height of the existing southern room is matched in the new addition.
The addition has wood lap siding, corner boards and other trim to match the historic
house.
The windows match the proportion of the south-facing window in the rear addition.

MINUTES PRELIMINARY
HISTORIC PRESERVATION COMMISSION
JUNE 13, 2024 – 5:30 PM – FORMAL MEETING
EMMA J. HARVAT HALL, CITY HALL
MEMBERS PRESENT: Margaret Beck, Carl Brown, Andrew Lewis, Jordan Sellergren, Noah
Stork, Deanna Thomann, Nicole Villanueva, Frank Wagner
MEMBERS ABSENT: Christina Welu-Reynolds
STAFF PRESENT: Jessica Bristow
OTHERS PRESENT: Simon Andrew, Martha Norbeck, GT Karr, Mark Russo
CALL TO ORDER:
Sellergren called the meeting to order at 5:30 p.m.
PUBLIC DISCUSSION OF ANYTHING NOT ON THE AGENDA:
None.
CERTIFICATE OF APPROPRIATENESS:
HPC24-0038: 426/430 Church Street – Goosetown/Horace Mann Conservation District (garage
demolition):
Bristow noted this is in the Goosetown/Horace Mann Conservation District on the corner of Church and
Van Buren. 426 Church Street is the house and it had aluminum siding removed recently so some of
the photos she showed were old. 430 Church Street had a long-term owner and it has recently
changed hands. The subject of the project is the shared garage between the homes. The houses were
built on a lot that used to extend all the way to the alley and then it was divided in half north and south
and then divided again in half east and west. Both homes are catalog homes built about the same time
and have a shared driveway and a shared garage.
Bristow said the issue with the garage is that it's 16ft by 16ft and a legal parking spot is 9ft by 18ft so it
is too short to fit modern cars. Since the 426 property was purchased by the current owner they've
been talking about this garage. With the previous owner there was no need for the corner property to
have driveway or garage space but then the property changed hands and now both property owners
are interested in being able to park on their property so that they don't have to park on the street. Staff
has been working through this for a long time with the homeowners trying to figure out ways to first
save the garage but there was no way to just add to it and make it workable, especially for two cars,
and Iowa City's zoning code does not allow a garage to be built that crosses property lines. They need
to have required setbacks, which can be reduced, but not to zero. The current garage not only crosses
the property lines but it also is within a foot or two of the rear property line and all of the properties have
to maintain a certain amount of open space. For the corner property, adding a driveway off the side
street and putting a garage in the backyard would mean that they have no open space. So the solution
they came to was that the garage would need to come down.
Typically the Commission would look at the condition of the garage prior to approving demolition and
this one does need repair. It has been repaired in the past, the doors are bead board with the framing
HISTORIC PRESERVATION COMMISSION

on the outside but garage doors can be replaced and they can also repair the garage itself as it is not
beyond repair to the point where they would normally allow demolition. However, in this case the only
way to allow both of the properties to have a place to park is to remove the garage.
The proposal is to take down the garage and have a parking pad on each side of the property line.
They do plan to separate it by 6 inches, Bristow is not really sure exactly why they plan to do that
perhaps due to some code requirements that a property owner doesn’t have water that drains from one
property to another. Also, when driveways are on the property line it's required to curb them so that
the water just does not run onto the adjacent property but in this case it would be difficult for either
vehicle to really get from the shared driveway and the apron into the space if it was curbed so it will just
become a parking pad.
Bristow stated that again they don't tend to approve a demolition for a building that is not beyond repair
and if they have a contributing building and it's going to come down they typically require a new one is
constructed, especially a garage to avoid surface parking, especially in a rental neighborhood. She
explained that is not possible with this project so staff does recommend that the Commission approves
the demolition so that the property owners can have parking. Bristow stated it would need to be
approved through the use of an exception, and the recommended motion is to approve the project
using an exception for the uncommon situation of very small lots with a shared driveway.
The guidelines related to this special exception are that sight and landscaping, the provided parking is
behind the primary structure which they'll be doing. There is not a new driveway, they're using the
same one, but the guidelines talk about driveways being 8ft to 10ft in width which this does comply
with. The guidelines also stated to have driveways typically from an alley if possible but there's no alley
here. In the guideline section about demolition it talks about retaining historic garages and designing
replacement garages but again that will not work in this situation.
Lewis asked about the limitations on where a garage can go and why that is not the same for parking
pads. Bristow believes the parking pads can be closer to the property lines as it is just concrete on
grade.
Stork asked if they would be allowed to put any type of covering over these parking pads. Bristow
replied no, they would not be able to have a carport due to City zoning code. Stork asked if carports
have the same limitations as garages. Bristow doesn’t know if they're exactly the same but they're
similar as again they don't want a structure near the property line because if there's a structure fire it
spreads to the other property, that's one of the reasons for setback requirements.
Thomann asked if there is any way for them to come back in a couple years and request a garage.
Bristow replied again no, there's no possible way. Had this garage been taken out by say a tornado
they could rebuild it within a certain limited time period regardless of the zoning code because if
something's taken out by weather or fire it is allowed. However, they wouldn't have been able to make
it bigger to fit two cars. Bristow also noted they had looked at options to add weird little bump outs so
that they could come in and park, or to add a lean-to extension and that would solve the length issue
but it wouldn't solve the problem with only one being able to park one car in it.
MOTION: Wagner moves to approval of a certificate of appropriateness for the project at 426
and 430 Church Street as presented in the staff report using an exception for an uncommon
situation. Villanueva seconded.
Thomann noted it really is an uncommon situation and feels bad because the garage reminds her so
much of her own garage but of course she does haven’t to share it.

Sellergren is curious if they are planning on just fully demolishing it or if they going to put it up on
Craigslist. She always asks about garages because she needs one. Bristow is unsure.
Stork is curious how common this is in districts to have shared garages. Bristow replied she knows of a
few shared garages but all of the other garages that she knows about are of a size where two cars can
actually park in them.
A vote was taken and the motion passed 8-0.
HPC24-0040: 726 Ronalds Street – Brown Street Historic District (new construction):
Bristow noted there may be some places in the report and agenda that list the address as 728 but the
address is 726 Ronalds Street.
This is in the Brown Street Historic District and previously the property had been divided with the
student-built house built on the western lot and this application is for the house construction on the
eastern lot. Bristow noted there are quite a few guidelines, and they're all listed in the packet, but one
of the important parts of new construction in a district is choosing a style. The Foursquare style was
chosen partly because of the fact that there are so many in the neighborhood. While it's definitely
prevalent in the neighborhood there's quite a variation between them. A basic Foursquare is generally
cube shaped, often slightly rectangular, with a hip roof and then a regular pattern of windows basically
in each corner of the square. Some of these houses are from a transitional period so the roof type may
vary. The Foursquare came out of the development of the Prairie Style so they often have a wide
overhang. Submitted as part of the application were some catalog homes that provided inspiration for
the design.
Bristow shared the site plan noting where the first house that was built on the west side and the
property line that divides the lot in half, she reminded the Commission there was an odd sewer
easement that very much impacted the depth of the house on the western lot which then impacted the
style and what type of architecture would be used. This house on the eastern lot has a little bit more
room but there is a steep drop off from the sidewalk, there is only about 10ft or so and then it drops off
sharply to the backyard and so that also impacted the design.
Bristow said it will be a rectangular Foursquare with a full width front porch and a walkout basement in
the sunken area of the backyard with retaining walls around it. The front facade of this house will have
three columns, it is typical to often have three columns if they're the thinner columns. However many of
the Foursquares with Classical Revival details, like in the Longfellow neighborhood to the south, have
large piers and box or ganged columns and so they'll have two instead of three. Bristow pointed out the
pattern of double hung windows in a matching pattern. She showed the rear elevation and where on
the foundation a door will be cutting through grade and the stairs going down away from the door. The
retaining wall will require a railing along it because it'll be greater than 30in. tall. The basement plan
walks out and there's the steps up to grade, so it is a sunken patio area, there's a bedroom with an
egress window, a bathroom and mechanical stuff. On the first floor is the main entry with the dining
room, the kitchen, living room and a bedroom and bath. Upstairs is a series of bedrooms and a
bathroom.
Bristow said the Housing Fellowship owns the property and has a goal to be able to house some larger
families so having this many bedrooms would allow them to do that. Bristow also noted the building
HISTORIC PRESERVATION COMMISSION
June 13, 2024

inspections and zoning code staff have noted that they would not be able to turn the basement into an
accessory dwelling unit so it would not be able to be a separate living space.
All new buildings follow guidelines related to how big the façade is and this one is just over half the
limitation so it's fine, the height of the building being one and a half or two stories, the front setback is
consistent with the neighboring property, adding doors that match what is typically seen on a historic
building and using siding that is consistent, in this case a smooth LP product with a flat casing. The
windows have been submitted as part of the project and is a window that has been approved before.
One of the issues is the guidelines do require that a new construction in a historic district is built so the
first floor is at least 18in above grade. Iowa City has had very few new constructions in a historic
districts, one of them was a Habitat home over in the Dearborn Neighborhood which is a Conservation
District so they did require that the front porch on that house be 18in above grade as they were able to
create their zero step entry, which is required on all new constructions, at the back door which was right
next to the garage and would be the main way that the occupants of the home would enter the house.
In this case because of the fact that the lot slopes so drastically off in the back it's not possible to have
a zero step entry into the main living space at the back. This is also the case with the property next
door they're creating that zero step entry at the front porch and therefore an exception needs to be
made to allow that. Also, because the porch floor will be concrete and the guidelines would have any
new porch on any property traditional porch construction, an exception would need to be made for
having just a concrete slab on grade.
Bristow said the American Foursquare styles often have attic dormers or roof dormers on their hipped
roof but this one does not, partly to reduce cost and complexity since they do have students that are
building the house. There are many examples in town of Foursquares without roof dormers so staff
finds this acceptable. One of the questions was about the porch columns. The porch columns as
drawn are considered a round classical revival column but because of ease of construction and
everything they would prefer to do a square column and staff finds that it would be acceptable to do a
square column but with some added conditions to make sure that they're sized properly. The staff
recommendation for this application includes conditions that the door product information and the porch
column design are reviewed by staff.
Sellergren is curious if there is a side door on this house. Bristow replied no, there's the rear door on
the basement level but no side door.
Bristow noted an entry canopy is something that they might want to consider adding over the back
door.
Wagner stated it's not required because of the grade, but he noted they might consider some type of
porch railing for accessibility and ease of access to the home at the front door. Bristow said it’s not
required but they did consider that.
Simon Andrew (The Housing Fellowship) stated they are very pleased with how the first house turned
out and they are excited to get the second one going.
Bristow also wanted to point out the plan for the basement shows a window on the side and it's not
included in the elevation because of the fact that they have already accomplish the required egress
window on the bedroom on the back. Staff would assume that this is a traditional basement window
size as that would also prevent them from having to put a window well into the side of the hill and the
setback requirements that are involved with that.
HISTORIC PRESERVATION COMMISSION

Martha Norbeck (C-Wise) stated these are her drawings so everything mentioned she has thought
about. With the basement window they need to have a 24in deep open web trust so that they can run
the duct work so that means that basement window is suddenly 24in down from the water table and
they have to have a window well and that adds so much cost and complexity and they already the door
with the light and the egress window they’re going to wind up with no window there. It would have been
great to have the extra light in there but from a logistical standpoint it just won’t work and again since
this is a student build they don’t want to be too complicated. Also, a lot of these decisions are being
driven by cost for the Housing Fellowship as well as the constructability for the students. They’ve
already got the guard rail necessary for the entry in the back and had the stairs there so to add the
railing going up to the upper level made the kitchen/living room situation untenable by creating that
access to that door. She wound up actually deciding to make that first floor room an accessible
bedroom and accessible bathroom, which takes up a lot of space, and to make the living room and
kitchen work in a way that actually felt like a place she would want to live and therefore got rid of the
first floor back door which saves the cost of the overhang over that exit and then it also saves the railing
and the landing at the at the top.
GT Karr (General Contractor, Sueppel’ s Building and Remodeling) wanted to take the opportunity to
talk about the positive things and how things turned out at 728 Ronalds Street. They had 16 students
on the build, they’re going to have a family that's a block away from Mann moving in and they got
affordable housing ,LEED gold certification, historic district house on the Parade of Homes. He noted
they had a 20-year hiatus from student builds but have 26 students involved for next year. His favorite
story is it's been on the parade and other than just seeing the kids and the turn out from the
neighborhood and all the positive feedback, the Parade of Homes is judged by other home builders’
associations, people in construction from Des Moines and Davenport, they judged this home against
the half million dollar homes. He’s had 150-200 people go through the house last weekend as well but
when people in construction who are doing it for a living think they just redid a house and not build from
scratch, that is showcasing the good work the students did.
MOTION: Lewis moves to approve a certificate of appropriateness for the project of 726
Ronald's Street as presented in the staff report with the following conditions: the door product
information and porch column design are reviewed by staff. Beck seconds the motion.
Thomann noted she was able to be at the open house on Saturday to see the new home there and it
does look like an old home that got a facelift so they did a really good job and she is also pleased with
this design too and excited to see something that will accommodate even a bigger family.
A vote was taken and the motion passed 8-0.
HPC24-0045: 1210 Sheridan Avenue – Longfellow Historic District (rear addition):
Bristow stated this house is in the Longfellow Historic District and is a Minimal Traditional with an
entryway that is Tudor Revival because of the asymmetrical steep angle of the roof. The lap siding with
the mitered corners is pretty much the only ornamentation on this home, there had been shutters on it
at one point in time, but it is unknown if those had been added or were historic. Bristow noted the
grade dropping off behind the house. The windows on the house have been repaired recently.
Showing an image of the back elevation of the house Bristow pointed out a little door and a bump that
she is not entirely sure when that was done.
Bristow showed the 1933 Sanborn Fire Insurance Map and noted this house was pasted in and that
means that it's an alteration to that Sanborn Map. Iowa City’s copy of the maps were altered eight
HISTORIC PRESERVATION COMMISSION
June 13, 2024
Page 6 of 11
different times up until the 1970s and so there are a lot of pasted in pieces but that is consistent with
the fact that they think this house was built in the 1930s and it would have been built after 1933. The
picture on the map does have that projecting entry but it does not have a bump out on the back.
Bristow did note sometimes Sanborn Maps have errors but not too often so she would tend towards
thinking this is accurate. She also looked back through the old housing inspector’s forms where they'd
sketch properties and make notes of things and the first time they visited this house was 1973 and it did
have the bump out at that point in time so she is assuming because of the Sanborn Map it was an
addition that happened within the first 30 years or so of the house being built. When she was talking to
the owner who proposed an addition Bristow noted that little bump out complicated things quite a bit as
they have a very small house and so they want to make any addition simple and not complicate the
house too much. She was not sure how they would resolve the roof and some of the set-in
requirements because of the grade falling off.
Bristow used the property information viewer image and sketched in where an addition would be and it
looked like they do drop two feet or so by the time they get from where the current back is to the new
back of the house. Bristow showed the existing house plan with a living room, kitchen, two bedrooms
and a tiny hall bathroom. The proposed addition is to increase accessibility because as of right now to
come into this house and go to either of the bedrooms one would have to enter into the small hallway
with doors that don't allow for wheelchair accessibility. The plan proposes an addition where that bump
out is. Where the bedrooms were in the original plan, one is now labeled closet and it will have the
window replaced with a door that goes into a large bathroom that's accessible and a large bedroom that
is also accessible through the kitchen area. The roof issue is resolved by basically removing one wall
of the bump out and the roof will be replaced to go over the entire addition including the porch.
Bristow compared the existing rear elevation noting the existing door and the two windows and looking
at the new addition elevations. She noted that the new addition is set-in on the west side and the wall of
the new bedroom is technically set-in on the east side as well by encapsulating both the existing bump
out and the new addition under the one roof it keeps it simple for a small house. Staff would
recommend approving this addition even though it doesn't necessarily fit some of the ways they
normally like to see additions done as they’re not maintaining the roof on that little bump out but
removing it and basically keeping the little salt box that was probably built historically with a crossing
gable coming off the back. The main gable roof of the house is much taller so they won't be seeing this
addition from the front and since the new wall is set-in that won't be visible either. The porch will have
the beam that is typically seen on a porch. The one thing that did come up in the guidelines was the
guidelines are very clear that a new porch must be built with traditional porch construction which means
that the one column will have a pier under it and whether or not there is skirting under there would be
up to them because it's going to be close to grade but it would need to still have that traditional porch
construction. Also doing so would help them reduce the size of their foundation so it might help reduce
the cost too.
Bristow showed the west elevation and the entryway to the existing house and the addition. She noted
the windows will be separated by framing with a piece of trim instead of being ganged directly together.
On the east elevation she pointed out where the existing bump out area was on the existing house and
the recessed area for the new addition. She noted they don't want to see a large expanse of wall that
doesn't have a window in it but because this is also recessed into the porch staff doesn't find it really
concerning. Bristow shared some of the guidelines such as doors trimmed to match other doors,
preserving the original roof pitches and spans at least with that front salt box at the entry and all of that,
preserving the original walls and vertical corners that define the massing of a historic building and while
they are not preserving the roof for that bump out they are setting in from the northwest corner and
preserving the actual bump out, adding windows that match the type and everything of the historic
windows, adding new windows in a location that's consistent and this does have a few more paired
HISTORIC PRESERVATION COMMISSION
June 13, 2024
Page 7 of 11
windows on the back that are somewhat traditional in spacing so staff didn't find that concerning.
Bristow noted again they want the addition to be set-in so they can distinguish between the historic
structure and the new but yet still need to match the eave lines, the window sill and head heights and
those other horizontal lines on the building. The siding will match, it will be a lap sighting that has
mitered corners to match the historic house, the foundation will need to match.
The recommended motion for this project is to approve it with the conditions that the porch follows the
traditional porch construction since the drawings didn't indicate that and that the windows are revised
as noted and approval of the door product.
Thomann is curious as they’ve got the porch that's at the back of the house but the stairs are coming
off to the side, why not off the back. Bristow stated in this case it is because of the slope and change in
grade to avoid a larger number of stairs.
Sellergren asked if there are any guidelines about having a porch or stairs off the side. Bristow is not
aware of any, it is required that the stairs have closed risers and some other things that are part of the
design but the only time they would really want a stair on the back is if it was a two-story stair for
something that's maybe not as historical. But if that is an issue for the Commission they could discuss
it further.
Mark Russo (1210 Sheridan Drive) is here with his wife Diana and stated the whole purpose of this
addition is that as they age they want to get into a simpler arrangement and this is all one floor. He
acknowledged the grade doesn't cooperate real well but it would be easy to grow old in this house
because it’s all one level. He noted the reason the stairway is on the side is because there's a flat area
of grade at the back of the existing bump out that’s about 8ft and then there's a drop off of at least 30in
or more and there's nothing in the back except a yard so that stairway needs to return whoever is using
it to the front which is unfortunately where they have to park because whoever landscaped this house
years ago did not allow for any garage nor the ability to put in a garage unless they build a 10-ft
retaining wall to the east and that’s just not going to happen. If they did go to the north with the
stairway it would have to be probably a 15ft stairway they’re trying to avoid those issues. Also,
regarding the age of the bump out, it wasn't in that original drawing but the siding is all continuous, so
he has a hard time believing that this siding was removed to accommodate the bump out. The siding is
mitered so it starts at the south end and goes all the way to the north end and additionally in the
basement the cement wall was framed and not cut because there is a funny little storm shelter
underneath, and somebody built a cement bench. This was all likely done in 1939 or 1940, prior to the
nuclear age but that's what he knows about that and it might have been original. He will have to go
back and look at it all more closely, it's an odd little structure that is a little dining area off of the kitchen
and it's about 6 by 6 so two people can have breakfast or dinner in there but that’s all. They did
recently rebuild the windows by Wadsworth Construction and bought storms from Adams Architectural
so all the fenestration is original and completely working. His hope is they can find a manufacturer that
at least in terms of look can replicate that. This house has been gone through the mill apparently it was
owned by a an anthropology professor who left every summer for an archaeological dig and turned the
yard over to the neighborhood as a community garden but it was really never attended to and up close
the siding is really an issue because it's all peeling and there's so many layers of paint that have been
applied and then blistered off.
Bristow noted when she looked at the past inspector's notes both of the times they said it desperately
needed to be scraped and painted. Russo stated four years ago they had it scraped and painted and
now are right back to it looking as it did before. He is afraid he’ll have to be a little more aggressive do
a project and perhaps have the siding removed and run through a machine to get it off because they
HISTORIC PRESERVATION COMMISSION
June 13, 2024

just can't scrape it off and there are also issues of lead, but that would be a different project to discuss
later.
Wagner had a question about which Sanborn Map Iowa City has because he stated one can go to the
Library of Congress and go to their Sanborn Maps and they have each year that it's issued. Bristow
acknowledged that but said they just don't have the 1930s ones and that may have something to do
with what's in the public domain.
MOTION: Beck moves to recommend approval of a certificate of appropriateness for the project
at 1210 Sheridan Avenue as presented in the staff report with the following conditions: the
porch follows traditional porch construction, windows are revised as noted, and door and
window product information is reviewed by staff. Wagner seconded the motion.
Beck noted this is a lovely house and appreciates them sharing their stories about it and really respects
and appreciates that they're wanting to age in place.
A vote was taken and the motion passed 8-0.
REPORT ON CERTIFICATES ISSUED BY CHAIR AND STAFF:
Bristow noted in an effort to not have as many projects without a permit they are going back to what the
Zoning Code really says and it does require that they review anything that requires a regulated permit
that makes a material change and is in a historic district. So that means they will be reviewing some
basic venting and stuff like that. Generally these are issued a certificate of no material effect and as
long as it's not in an impactful area staff is approving it. However now the Commission will see these in
the staff report.
Certificate of No Material Effect -Chair and Staff review
HPC24-0035: 722 East College Street – College Green Historic District (mechanical venting):
Bristow stated they have a kitchen area down in the basement of this church and are putting in some
vents. There will be one on the side wall and the rear, both in areas where they are not visible from the
street.
HPC24-0036: 903 Iowa Avenue – College Hill Conservation District (mechanical venting):
Bristow explained on the back of the house it will have a vent between a back entry and a window that
for a bathroom venting as they're adding a bathroom this house. This property is very interesting, it is a
key property in this Conservation District and yet it has synthetic siding. It was damaged during the
tornado.
HPC24-0042: 1501 Center Avenue – Longfellow Historic District (siding replacement):
Bristow stated one of the recent storms blew off the siding of this Moffit house. This house is
contributing to the District and has had synthetic siding applied but in this case they approved them to
just replace what's in the gable and they could match it and are going to paint it because that gable was
the only part that was damaged from the storm. Also the porch is a reconstruction, it would not have
had these spindle columns.
HPC24-0049: 515 Rundell Street – Longfellow Historic District (concrete stoop replacement):
Bristow noted this house changed hands recently and it's been glorious to see its transformation. It
was probably just a rental house before and now has been purchased by an owner who is completely
HISTORIC PRESERVATION COMMISSION
June 13, 2024
Page 9 of 11
reworking things which is exciting. This project is replacing the concrete stoop.
Minor Review – Staff review
HPC24-0017: 818 Rundell Street – Dearborn Street Conservation District (railing replacement and
exhaust venting):
Bristow stated this is a house on Dearborn that has synthetic siding, the porch has been reconstructed,
it is actually a house that would have never had these spindled columns or this spindled railing, the
railing is off the shelf from Menard's and it's way too small and too far apart in spacing. They needed to
replace the railing now since it's falling apart and staff suggested square spindles and to matching the
guidelines with the spacing.
HPC24-0047: 830 E Davenport Street – Goosetown/Horace Mann Conservation District (enlarged rear
stoop and stairs):
Bristow explained they're replacing the railing and on the back the house has several bump outs and
additions and several little stoops. One will be enlarged slightly and the railing will now follow the
guidelines.
Intermediate Review -Chair and Staff review
HPC24-0037: 820 Park Road – Local Historic Landmark (roof shingle replacement with shingle-style
metal roof):
Bristow explained it's time to replace the roof on this house and it has actually always had an asphalt
roof. This was a house built by an engineer and the City proposed to do a metal shingle and the Chair
and staff agreed that could fit within what Ned Ashton probably would have wanted to do given the fact
he was an engineer and given the fact that they have come pretty far in being able to make these
shingles look like historic shingles now. Bristow showed some examples of what the shingle tends to
look like when it's installed and the color that they're going with.
CONSIDERATION OF MINUTES FOR MAY 22, 2024:
MOTION: Wagner moves to approve the minutes of the Historic Preservation Commission's May
22, 2024. Beck seconded the motion. The motion carried on a vote of 8-0.
COMMISSION DISCUSSION:
Work Plan and subcommittees:
Bristow stated they started emailing about the awards and stuff so that's good. She was going to get a
list of potential landmarks from the past hasn’t done that yet.
Sellergren noted Ginalie from Friends of Historic Preservation sent out an email to all of their members
requesting nominations this afternoon. Bristow noted they try not award the same properties and the
same people all the time and also do awards for residential rehabilitation on anything on the exterior if
anyone has nominations. There are also stewardship awards for anyone who has maintained it for a
very long time over time. Sellergren stated the goal is to have a good list by July and the next thing
they'll need to do is pick a date and find a location.
COMMISSION INFORMATION:
Sellergren went to the forum but was only there for a few hours but it was very interesting and they got
a tour of Mount Pleasant. The town square is very nice with some really cool brick buildings like a large
HISTORIC PRESERVATION COMMISSION
June 13, 2024
Page 10 of 11
brick hotel in the corner of the square and the first woman lawyer in the United States was sworn in at
one of the buildings that's facing the square, the first courthouse in Iowa was located, there's also Iowa
Wesleyan College there which just recently closed, it has a lot of old buildings and was the oldest
college west of the Mississippi.
Bristow did a lot of tours and attended a session that was more geared to mid-century properties and
what's historic and working with them. One of the tours had to do with the Underground Railroad and
what's interesting is a town south of that had a large Quaker population and the Quakers felt that they
were not beholden to the laws of the land but beholden to higher laws and so they helped the Freedom
Seekers. They toured a house owned by a Quaker family where they had places basically below the
floor where people could hide. She also went on a tour that included the house that James Van Allen
lived in and one of the descendants of one of his brothers was there for part of the tour. There was
also a house that was lived in by one of Abraham Lincoln's sons and his wife. Sellergren and Bristow
both saw a tour related to rehab and Bristow went on another one that was adaptive reuse. Their city
hall building now is offices down below and apartments above. It’s a tiny city hall and not anything like
what Iowa City would have but interesting. It was a very good conference, and she made notes for
things that relate to Iowa City. Sellergren noted next year it's in Muscatine which will be interesting as a
river town.
Bristow stated the only other thing is Commissioner elections will need to happen at the July meeting.
Beck was reappointed and Stork is cycling off the Commission. Bristow thanked Stork for his service
and noted it has been very good to have him on the Commission because it is necessary to have a
dissenting opinion as they do not need to be a unanimous voting body and it's very valuable to have
people like him who live in the District and know what's going on be on the Commission.
Wagner discussed the Terrace Mound open house on Saturday, it’s a house he has been working on at
5053 Highway 6 East, right across from Kinder Farm. It is an 1873 house that has been renovated and
restored, the open house is Saturday from 1pm to 4pm.
ADJOURNMENT:
Villanueva moved to adjourn the meeting. Lewis seconded. The motion carried on a vote of 8-0.
