Re: Update on Research and Policy Questions regarding Possible City-wide Transfer of
Development Rights Program for Historic Preservation
Introduction
At the City Council's May 29, 2018 meeting the Council considered the local landmark designation
of the property at 410-412 North Clinton Street. At this meeting the property owner's attorney
requested that the Council defer action on the local landmark designation until the City reviews
and analyzes the establishment of a city-wide transfer of development rights (TDR) program for
historic properties. The Council voted to defer action on the local landmark designation until the
end of January 2019 and directed staff to explore the creation of a city-wide TDR ordinance.
At the August 7 work session, the City Council discussed the July 18 memo to the City Manager,
which provided an overview of TDR, summarized the City's existing TDR provisions in Riverfront
Crossings, and outlined potential receiving areas. At the work session, the Mayor expressed
interest in South Johnson and South Van Buren Streets from Court Street to the railroad tracks
being a receiving area if an urban design plan existed for the area.
This memo provides an update on staffs research and analysis and outlines specific policy
questions for the City Council. In order to meet the January 2019 deadline, staff needs direction
from the City Council on the following: the formula for calculating the transfer of development
rights,the priority of preserving historic resources compared to bonus provisions currently offered
for other public benefits, the process for the review and approval of development transfers, and
areas to further pursue as receiving sites. In general, staff recommends a program that is fair,
legally-sound, easy to administer, and simple to understand. Additionally, staff wants an effective
program that preserves historic resources while not compromising the ability to achieve other
important comprehensive plan goals.
Overview of Research &Analysis
Sending Areas
Staff conducted an analysis of possible sending areas in order to estimate the potential for
development transfers. Staff estimated the amount of development that could be transferred
through a city-wide TDR program by applying the existing Riverfront Crossings transfer formula'.
Furthermore, the Riverfront Crossings TDR provisions require that prior to requesting a transfer
of development rights, the property must be designated as a local landmark. Therefore, in this
analysis staff applied the transfer formula to existing landmarks (see Table 1).
1 The formula for calculating the transfer in Riverfront Crossings is Lot Area of the Sending Site X Maximum
Number of Stories Allowed on the Sending Site =Square Footage Eligible for Transfer
August 30, 2018

Sending Sites Development Transfer Potential`
(square feet)
Local Landmarks Only 4,367,0683
Local Landmarks & National Register of 5,368,9974
Historic Places-Listed Landmarks)
The analysis conducted only looks at existing local and national landmarks. There are several
other buildings that are eligible for local landmark designation and the Historic Preservation
Commission has been proactively identifying sites to locally landmark.The City is also in the midst
of a survey of downtown historic properties. Several properties in the downtown are eligible for
local landmark designation.As more properties are landmarked the transfer potential will continue
to increase.
Staff reviewed several other TDR programs. Of the programs reviewed, none applied only to
future landmark designations. In other words, existing and future landmarks qualified as sending
sites. However, some cities required rehabilitation of the historic structure prior to becoming
eligible as a sending site.
Receiving Areas
The areas identified by staff as potential receiving areas include:
• Riverfront Crossings,
• Downtown,
• South Johnson and South Van Buren Streets between Court Street and the Railroad, and
• Land Designated for Multi-Unit Development throughout the city.
Using these areas, staff conducted an analysis to determine the amount of existing development
potential (see Table 2). For the analysis, staff identified vacant and underutilized sites within the
potential receiving areas. The following areas were removed from the analysis: land within the
500-year and 100-year floodplains, local historic landmarks, local historic districts, conservation
districts, and publicly zoned land. In addition, several historic properties in the downtown were
removed from the analysis. For a more detailed outlined of the methodology, please refer to
Attachment 1.

Accommodating the potential development transfers depends on a number of factors, including
the eligible sending and eligible receiving sites. Another option to consider that could also help
preserve historic structures is a parking reduction. Instead of transferring development rights, the
receiving site could purchase the right to receive a parking reduction. Staff has not explored this
thoroughly. More research is required to better understand the viability of this option.
Other Local Jurisdictions' TDR Programs
Staff also reviewed other local jurisdictions' TDR programs across the country that focus on
preserving historic resources. For a more detailed overview of other programs, please refer to
Attachment 2.
Transfer Formulas
There are different ways to approach calculating the transfer rights from a sending site to a
receiving site. Several cities consider the existing development on the sending site. More
specifically, these cities calculate the transfer by taking the maximum development potential of
the sending site less the existing development on the sending site. To provide an incentive, many
cities also allow development to exceed the maximum allowable density/intensity on the receiving
site. Table 3 outlines some examples.
Table 3. Example Transfer Formulas
Local Jurisdiction Transfer Formula
Chico, CA (Max density of the sending zone X Acreage
of sending site) Less (Existing and proposed
Number of dwelling units on the sending site)
*Receiving site bonus above that allowed by
comprehensive plan
Minneapolis, MN (Max allowable floor area of the sending site)
Less (Floor area of existing development on
sending site)
*Receiving site bonus of 30% above max
allowable floor area
Pittsburgh, PA (Max allowable development) Less (Existing
amount of development)
*Receiving site density bonus of between 20%
and 200%
Providence, RI (Max allowable height) Less (Height of historic
landmark)
*Receiving site bonus height of 1.6 times the
max height or 300 ft, whichever is less.
Vancouver, WA (Max allowable floor area of the sending site)
Less (Existing floor area of the sending site)
*Receiving site development must not pose
hazard to low-flying aircraft.
West Hollywood, CA Residential: (Max allowable dwelling units)
Less (Existing number of dwelling units)
Commercial: (Max allowable floor area) Less
(Existing floor area)
*Receiving site FAR bonus allowed through
Planning Commission review and approval.
West Palm Beach, FL (Lot area X Max allowable floors) Less (Floor
area of existing structure)
*Receiving site height bonus.

Compared with these other local jurisdictions, the City's current transfer formula in Riverfront
Crossings is very generous. Unlike the examples above, the formula in Riverfront Crossings does
not take into consideration the existing development on the sending site. In establishing the
transfer formula for Riverfront Crossings, staff anticipated a significant amount of redevelopment
pressure, and therefore, intentionally recommended a generous transfer formula in order to
incentivize the preservation of historic resources.
Approval Process for Transfers
TDR programs also vary in how the sending and receiving of transfers are reviewed and
approved. Many jurisdictions have a process that requires review by either the City Council or a
board or commission. Table 4 provides some examples of how other local jurisdictions review
and approve transfers.
Table 4. Examples of TDR Processes
Local Jurisdiction TDR Approval Process
Chico, CA Non-administrative: City Council approval
required
Minneapolis, MN Administrative: Review and approval by
Planning Director
Pittsburgh, PA Non-administrative: Historic Preservation
Commission approval required
Providence, RI Non-administrative: Downtown Design
Review Committee approval required
Vancouver, WA Non-administrative: City Council approval
required
West Hollywood, CA Non-administrative: Cultural Heritage
Advisory Board reviews and approves
rehabilitation plan
West Palm Beach, FL Non-administrative: Downtown Advisory
Committee review and approval required
The City's existing TDR provisions require that the City Council review and approve any transfer
of development rights request. Although several of the example jurisdictions above include the
equivalent of the Historic Preservation Commission in the review, some also require review and
approval by the City Council. Only one jurisdiction, Minneapolis, MN, reviews and approves
transfers administratively.
Administration & Tracking
Staff also looked at how other local jurisdictions administer and track TDR programs. Table 5
outlines some examples from other jurisdictions.
Table 5. Examples of TDR Administration &Tracking
Local Jurisdiction Tracking Mechanism
Chico, CA Documented in adoption of Specific Plan or
Planned Unit Development or executed

Providence, RI Owners of sending and receiving sites
execute a deed or other agreement to be
recorded with the title to both sites.
West Hollywood, CA City staff maintains a list of eligible sending
sites to assist potential receiving site
developers.
West Palm Beach, FL City staff maintains a registry of development
rights available and transfers. Execution of
City-approved restrictive covenant that
outlines transfer. Covenant recorded against
the sending and receiving sites and added to
City registry.
There are a variety of methods that other jurisdictions employ to administer and track TDR
programs, some are more complex than others. The Riverfront Crossings TDR provisions do not
outline a method for tracking transfers. Currently, planning staff maintains a spreadsheet of
approved transfers and the applicable sending and receiving sites. More formal tracking
mechanisms should be contemplated in a city-wide TDR program and developed in coordination
with the City Attorney's Office.
Receiving Areas
Table 6 outlines other jurisdictions' receiving areas.
Table 6. Receiving Areas
Local Jurisdiction Receiving Areas
Chico, CA Applicant must demonstrate that the proposed
receiving site can accommodate the additional

downtown.
Vancouver, WA Sites with the same zoning district as sending
site.
West Hollywood, CA Medium and high-density commercial zones.
Do not allow transfers into residential zones.
West Palm Beach, FL Specific sites identified in the downtown.
Issues/Constraints
Several cities across the country have adopted TDR programs to preserve historic resources and
some are more effective than others. There are variety of factors that could impact the success
of program, which are outlined below.
Market Potential
At this time staff does not have a market study that examines the market potential for a city-wide
TDR program and completing a market analysis within the timeframe required is not feasible.
Therefore, it is unclear whether a demand for such a program exists.
Lack of Certainty in the Process
Another factor that could impact the effectiveness of a TDR program is how transfers are reviewed
and approved. Programs that allow by-right transfers that are reviewed and approved
administratively provide more certainty for developers. Programs that require a discretionary,
public process provide less certainty and more risk to developers.
August 30, 2018
Page 6
Other Bonus Mechanisms
Some of the more effective TDR programs provide few or no other alternatives to achieving
additional development potential. If other mechanisms exist to developers to achieve more
development potential it could impact the effectiveness of a TDR program. Some examples that
the City currently offers in Riverfront Crossings include bonuses for public art, Class A office
space, affordable housing, and energy and environmental stewardship.
Policy Questions for Council
The most fundamental question for City Council is whether they wish to continue to pursue a city-
wide TDR program to preserve historic resources. If the City Council would like staff to continue
to pursue a city-wide program, staff needs direction on the following policy questions:
1. Should eligible sending sites include existing local historic landmarks or only
future local historic landmarks?
The City has 52 local historic landmarks and the Historic Preservation Commission is
working to identify and designate more local landmarks. In addition, the downtown
includes a number of properties that are eligible for local landmark designation.
Some options include:
a) Eligible sending sites include existing and future local historic landmarks
• Pros:
i. Fair
H. Consistent with the Riverfront Crossings TDR provisions
• Cons:
i. Depending on the transfer formula and the identified receiving sites
the city may not have enough capacity to receive all of the potential
transfers.
b) Eligible sending sites only include future local historic landmarks
• Pros:
i. May be easier to accommodate the transfer potential
• Cons:
i. Inconsistent with the Riverfront Crossings TDR provisions
2. Should a city-wide TDR ordinance apply the existing transfer calculation formula
that is outlined in the Riverfront Crossings form based code or a new formula?
The transfer formula adopted in Riverfront Crossings was intentionally generous to
incentivize preservation in an area anticipated to be redeveloped. The formula does not
take into consideration existing development on the sending site; and therefore, results in
higher transfer potential. Using the same formula for a city-wide program provides
consistency and clarity between the two programs. It would also make administration and
tracking of the program easier. However, depending on the receiving sites identified there
may be an issue with the capacity available for development on the receiving sites.
Some options include:
a) Keep the existing Riverfront Crossings transfer formula.
• Pros:
i. More generous, could provide more of an incentive to developers
H. Consistency in administration, application, and simpler to
understand
• Cons:
i. More generous, may not be able to accommodate the amount of
potential transfers
August 30, 2018
Page 7
b) Establish a new transfer formula that considers the existing development on the
sending site.
• Pros:
i. May be able to accommodate the potential transfers with a less
generous formula
• Cons:
i. More complex and more difficult to administer
ii. May want to revisit the Riverfront Crossings transfer formula to
ensure consistency, which would require more time
3. The City already gives bonuses for certain public benefits provided with
development projects. Should preservation of historic resources be treated in a
similar manner or given a higher priority?
Several other programs across the country provide an incentive to transfer development
rights by allowing a density or intensity bonus on the receiving site. This comes in many
forms: height increases, additional floor area, and additional dwelling units. The City's
zoning ordinance currently includes several bonus provisions.
In the central business district zones (i.e. CB-2, CB-5, and CB-10) bonuses are reviewed
and approved administratively when development projects provide the following types of
public benefits:
• Masonry finish;
• Provision of a theater;
• Funds for street furniture, lighting, and landscaping within the public right-of-way;
• Open space;
• Adaptive reuse of certain historic properties;
• Provision of off-street loading areas that meet specific requirements; and
• Provision of class A office space."
In the planned high density multi-family residential zone(PRM)bonuses are reviewed and
approved administratively when development projects provide the following types of public
benefits:
• Materials, specifically masonry finish;
• Open Space;
• Rehabilitation of a historically significant building;
• Assisted housing;
• Streetscape amenities;
• Landscaping; and
• Installation of window units that have a height that is at least 1.5 times greater
than the width.12
In addition to the bonuses offered for transferring development rights, height bonuses may
be requested in Riverfront Crossings for several public benefits. Requests to exceed the
base height by two stories are reviewed and approved administratively. Requests to
exceed the base height by more than two stories are reviewed and approved by the City
Council. Bonuses are reviewed for the following public benefits:
• Class A office space;
• Public art;
• Energy efficiency and environmental steward through Leadership in Energy and
Environmental Design (LEED) or a similar program;
• Student housing;
11 For more detail on these bonus provisions please see 14-2C-8.
12 For more detail on these bonus provisions please see 14-2B-7.
August 30, 2018
Page 8
• Hotel space;
• Workforce or affordable housing; and
• Elder housing.13
Some options include:
a) Model a city-wide TDR program on the current bonus provisions offered in the
central business district zones, planned high density multi-family residential zones,
and Riverfront Crossings.
• Pros:
i. Simpler and easier to administer
• Cons:
i. Bonuses for multiple public benefits may dilute the effectiveness of
preserving historic structures
b) Allow transfers for historic properties to exceed the City's current bonus provisions
(e.g. offer more height, more density/intensity).
• Pros:
i. Offering more of a bonus may be more of an incentive to preserve
historic resources over bonuses offered for other public benefits
• Cons:
i. Community concerns with additional density/intensity and height
H. An analysis of the potential impact of an additional bonus would
take time to evaluate
4. What type of process should be established for the review and approval of sending
and receiving transfer of development rights?
The City's existing TDR provisions require review and approval by the City Council when
a transfer of development rights is proposed. In staff's review of other TDR programs
several require a non-administrative review and approval; however, some jurisdictions
review and approve development transfers administratively in order to streamline the
process and provide some certainty.
Some options include:
a) Keep the existing Riverfront Crossings review and approval procedure by City
Council.
• Pros:
i. Simpler and consistent with current process
• Cons:
i. Lack of certainty in the approval process
b) Establish a new procedure that allows transfers up to a certain height or
density/intensity to be reviewed and approved administratively. This could be
similar the City's existing central business district bonus provisions or certain
Riverfront Crossings' bonus provisions, which are reviewed and approved
administratively. Any transfers beyond an identified threshold would be reviewed
and approved by the City Council.
• Pros:
i. Streamlines the review and approval of transfers
H. Allows the City Council to review and approve larger transfers that
would potentially have more of an impact
• Cons:
i. Not consistent with current process
13 For more detail on these bonus provisions please see 14-2G-7.
August 30, 2018

5. What areas should a city-wide TDR ordinance identify as receiving areas?
Staff has proposed a few options for potential receiving sites:
• Riverfront Crossings,
• Downtown,
• South Johnson and South Van Buren Streets between Court Street and the
railroad tracks, and
• Sites throughout the city that allow multi-unit development.
Based on the analysis staff conducted there is limited development potential in the
downtown due to the number of historic structures. There is also limited potential for
redevelopment along South Johnson and South Van Buren Streets since none of the sites
in this area met the threshold needed to be identified as vacant or underutilized.
Furthermore, the Mayor expressed interest in this area as a receiving site only if
accompanied by an urban design plan. Staff could explore the development of an urban
design plan for this area, but completing a plan by the January 2019 is not feasible. The
most capacity exists on multi-unit zoned parcels city-wide. Riverfront Crossings also has
capacity, if the area is rezoned to the Riverfront Crossings zoning designation.
Some options include:
a) Riverfront Crossings, and/or
• Pros:
i. Current receiving area
ii. Master Plan and form-based code encourage higher
densities/intensities
• Cons:
i. May not be able to accommodate the amount of transfer potential
for a city-wide program
b) Downtown, and/or
• Pros:
i. Core of the community with existing infrastructure
ii. Commercial zoning allows for higher densities/intensities
• Cons:
i. Significant amount of historic buildings; and therefore, not able to
accommodate much transfer potential
c) South Johnson and South Van Buren Streets between Court Street and the
railroad tracks, and/or
• Pros:
i. Transfers could provide an incentive for redevelopment
ii. Zoned for higher density housing
• Cons:
i. May require the development of an urban design plan, which would
take time
ii. May not be able to accommodate much transfer potential
d) Sites throughout the city that allow multi-unit development, and/or
• Pros:
i. Provides the most capacity for transfers
• Cons:
i. Could potentially be more impactful and cause concern from
neighbors
ii. Areas with sensitive features (e.g. wetlands, slopes, woodlands)
require a sensitive areas development plan which often leads to
August 30, 2018
Page 10
clustering. Transfers to these areas could result in even higher
densities.
e) Other sites or areas

Methodology for Vacant & Underutilized Sites Analysis
1. Potential Receiving Areas:
a. Riverfront Crossings'
b. Downtown
c. South Johnson & South Van Buren Streets between Court Street &the Railroad
d. Land zoned for multi-unit development, including commercial zones that allow
multi-family (city-wide)
2. Removed the following from the potential receiving areas:
a. Land within the 100 & 500-year floodplain
b. Local Historic Landmarks, Local Historic Districts, and Conservation Districts
c. Historic properties within the downtown
d. Publicly zoned parcels and other parcels that do not allow multi-unit development
3. Vacant& underutilized sites analysis:
a. Used Assessor data to identify vacant sites
b. Underutilized sites include the following:
i. Improvement-to-land value ratio of less than 1.0, which indicates that the
buildings on the site are less valuable than the land, and therefore, more
likely to be redeveloped
c. Staff also referred to the Riverfront Crossings Master Plan and the areas
identified for potential redevelopment
d. Additional sites were included based on staff's knowledge of potential future
developments
4. Calculated development potential of vacant & underutilized sites:
a. Commercially-zoned properties: Floor area ratio (FAR)
i. FAR converted to square footage by multiplying the maximum height by
the lot area
b. Residentially-zoned properties: Density (dwelling units/acre)
i. Density converted to maximum allowable dwelling units
c. Applied 80% discount factor assuming that maximum allowable density/intensity
will not be achieved

__ MEMORANDUM
Date: August 30, 2018
To: Geoff Fruin, City Manager
From: Juli Seydell Johnson, Director of Parks & Recreation
Zachary Hall, Park Superintendent
Re: Emerald Ash Borer
This memo is in response to a number of concerns and questions from City Council Members
and the public regarding the City's management of Ash Trees in response to infestation by the
Emerald Ash Borer. It is important to note that although many cities, in the early stages of EAB
infestation, removed all ash trees, this is not the response happening in Iowa City. Forestry
personnel are monitoring the health and condition of all trees, including ash, removing only
those that show signs of decline or need to be removed for a City infrastructure project. Tree
removal due to decline is necessary in order to maintain a healthy tree cover and limit public
safety concerns.
Staff has been asked to specifically consider chemical treatment of ash trees. The Staff
recommendation is to continue the current program of monitoring tree health, removing and
replacing trees as warranted by tree conditions. Chemical applications can prolong the life of
the tree, but do not ensure long-term survival. Instead, staff recommends that resources be
prioritized to continued efforts to reforest the community with diverse tree species throughout
the City. Additional information and rational for this recommendation follows.
Background
Emerald Ash Borer (EAB) has had the opportunity for large scale national invasion due to past
urban forestry practices in the aftermath of Dutch Elm Disease (DED). Dutch Elm Disease is
caused by the fungi Ophiostoma ulmi and Ophiostoma novo-ulmi carried by the Banded Elm
Bark Beetle Scolytus multistriatus. Most Elm tree varieties were/are susceptible to infestation
and the American Elm is the most susceptible. During the 1930s DED swept across the nation
spreading from Ohio outward and reached Iowa in 1956. By the 1970s the effects of DED were
realized nationwide with many communities condemning and removing the majority of their
urban Elm populations. This practice of sanitary removal of infested Elm trees left a void in
many urban forests that needed filled. Ash tree varieties were then seen as a new viable
resource adapted to harsh urban environments. Ash trees are hard wooded, fairly quick
growing, require little maintenance and, depending on variety, provide good shade and fall
color. During this time-period and, until the detection of EAB, American communities planted
varieties of Ash trees, particularly Green Ash, without restraint.
The Emerald Ash Borer (EAB) is an invasive wood boring beetle native to central Asia that
destroys Ash (Fraxinus) trees by using the tree as a food source and breeding host. EAB was
first introduced to the United States in Michigan in 2002 as the result of infested pallet shipping
material. Since its discovery EAB has spread to 32 states and 4 Canadian Provinces.
Diseased Ash trees pose a great public health and safety risk because the speed of decay,
leading to death of the tree, can be within a year of initial contact. Dying Ash trees become very
unstable and brittle and are easily prone to breaking, dropping limbs and collapsing.
Pre-EAB Infestation
Beginning in 2004, in response to the new tree pest (at that time), the City of Iowa City Forestry
division discontinued planting all Ash varieties on public property. In 2010, Emerald Ash Borer
August 30, 2018
Page 2
was discovered in Iowa in Allamakee County. That same year the City of Iowa City Forestry
division began removing marginally viable Ash trees located in the right-of-way, at the request of
property owners. This approach was to proactively prepare for and minimize the effects of a
future EAB infestation, educate homeowners about EAB and replant new trees where
appropriate. In June of 2014 an adult male EAB beetle was discovered at a private residence in
Iowa City. Despite the identification of the beetle, Johnson county was not added to list of
counties with confirmed infestations. At that time, 12 counties in Iowa had confirmed infestations
of EAB.
At the October 21, 2014 City Council work session, information was presented on the history of
EAB, status in Iowa and Iowa City and the strategy to remove and replace public ash trees with
a diverse mix of trees. Chemical treatment was not explored at that time due to a lack of
definitive research regarding long term effectiveness and a general move by the City toward
using less chemicals throughout our public lands.
In 2015, 223 trees were removed by the City. Thirty-four of these were ash trees (18 by staff, 16
by contract). That same year 384 trees were planted (84 by staff, 100 by contract, 200
saplings). In October 2015, Emerald Ash Borer was discovered in Linn County at an 1-380 rest
area, less than a mile from the Johnson County border. At that time 25 counties in Iowa had
confirmed infestations of EAB. Johnson County was still not considered to have the EAB
infestation.
Post-EAB Infestation
In February 2016 an EAB infested tree was discovered at Gibson's Square on the University of
Iowa Campus. In November of 2016, Forestry staff removed the first infested ash tree located
on city property. In 2016, 177 trees were removed in the City. Forty-one of these were ash
trees (16 by staff, 25 by contract). That same year 355 trees were planted. (75 by staff, 80 by
contract, 200 saplings.) During the FY 2017 budget process City Council allocated funds to be
spent on a comprehensive tree inventory to identify and assess 50,000 publicly owned trees.
In 2017, 297 trees were removed. One hundred seven were ash trees (41 by staff, 66 by
contract). That same year 578IsAl] trees were planted (102 by staff, 276 by contract, 200
saplings). In 2018, to date, 240 trees have been removed. Eighty-one were ash trees (27 by
staff, 54 by contract). 491 trees are scheduled to be planted in 2018 (50 by staff, 241 by
contract, 200 saplings).
Tree Survey and Urban Forestry Management Plan Development
In March of 2018, the comprehensive Tree Inventory was completed. 45,000 trees were
inventoried. Approximately 8 percent (3,500) were identified as ash trees. At the time of the
survey -7% of the ash trees were judged to be in poor or critical condition. However, this is
rapidly changing as the EAB infestation spreads, currently -9% of ash trees are in poor or
critical condition. Ash trees infected by EAB decline rapidly from the inside out, often making
the trees immediate safety hazards when the beetle or beetle damage is discovered.
The tree inventory is a planning tool for the City. It has given staff a better understanding and
identification of the urban forest, its makeup, health and areas of improvement. The tree
inventory provides data such as specific location, species, condition, and potential planting
sites. Staff will provide an overview of the inventory at the Council work session.
In addition, an Urban Forest Management Plan based upon the inventory data will be completed
by the end of the year. At that time a Tree Advisory Board will be created as a sub-committee
August 30, 2018
Page 3
of the Parks and Recreation Commission. This advisory board will help review and guide
forestry efforts on a regular basis.
Prioritizing Removals and Selecting Replacement Trees
The City of Iowa City Forestry Division, a part of the Parks & Recreation Department, is
comprised of five full-time staff. The Forestry staff includes some of the most credentialed
forestry professionals in the state with more than three decades experience in urban forestry
and arboriculture. Educational training includes an A.A. Degree in Parks and Natural Resource
Management, B.S. in Forestry with an emphasis in Urban Forestry and M.S. in Land Use and
Environmental Planning. Certifications include International of Society of Arboriculture Certified
Arborists, Certified Municipal Arborist and Tree Risk Assessment Qualification.
Forestry staff prefer to work in the management and improvement of trees. This includes
regular pruning. monitoring for health and advising on the best type and location for new trees.
The primary reasons that trees are removed by City forestry staff are either decline/damage
which makes the tree a public safety hazard or removal for a public infrastructure or park
project. A notification process is in place for communicating with homeowners before City trees
in the right-of-way are removed in front of any private property. Home owners are also
consulted on the species of replacement tree.
Chemical treatment of trees has not been used by the City of Iowa City for any species of tree.
This has been due to lack of long-term effectiveness versus the cost of many treatments.
Negative effects on pollinator plants and other plants and animals are not widely researched for
many of these treatments. Ash trees are not the only species affected by pests and disease
with an option for treatment. Treatments are also available for Oaks, Maples, fruit trees and nut
bearing trees.
Adhering to the Remove and Replace approach, staff have been removing marginal ash trees
and achieving approximately a 2:1 replant/remove ratio for all tree removals. Staff is
incorporating a diverse mix of species attempting to do better than the industry standard.

Diversification of the Iowa City tree canopy has been an effort of the forestry division since Ash
tree planting stopped in 2004. Examples of this diversification strategy can be seen with the
2017 Public Works planting project along South Sycamore totaling —200 trees with a diversity of
12.5% different genera, and the 2018 Public Works planting project along Camp Cardinal and
Lower West Branch Rd. totaling —200 trees with a diversity of —9% different genera. Industry
standards and best management practices recommend tree diversity of no more than 30% of
the same Family, 20% of the same Genus and 10% of the same species. Currently, the top
three genera identified in the City of Iowa City tree inventory are Maples (20%), Oaks (8%), and
Ash (8%). In the state of Iowa the top three genera of trees on public property are Maples,
Oaks and Ash.
Other Tree Pests and Disease
Emerald Ash Borer is the most current major pest and disease affecting the urban forest in Iowa
City. There are other pests and diseases on the horizon that may be as equally, if not more
damaging than Emerald Ash Borer. Gypsy Moth caterpillars feed on the leaves of oaks,
hickories and maples, defoliating the tree potentially to the point of death. Asian Longhorn
Beetle (ALB) is a wood boring beetle that attacks maple varieties using them as a feeding and
breeding host. Thousand Canker Disease (TCD) is a wood boring beetle that attacks walnut
trees using them as a breeding host. Bur Oak Blight is a fungus that damages, wilts, and can
defoliate Bur Oak trees. Oak Wilt is a fungus that fungus that damages, wilts, and can defoliate
Red Oak and White Oak trees.
Looking Ahead
Emerald Ash Borer management continues to evolve with researchers developing chemical
treatment options, biological controls and pest resistant strains of ash varieties. Communication
with state forestry officials, contractors and other communities in Iowa and the U.S. have made
it clear each community's response to EAB is different. For example, Cedar Rapids and
Coralville have chosen to implement a level of chemical treatment into their management
strategy. Both communities fully recognize this will not guarantee their ash trees will be saved,
but delay the time of removal to stay as much ahead of the rapid rate of infestation and tree
death as possible. The University of Iowa has taken the same Remove and Replace approach
as the City of Iowa City.
Currently, the best form of chemical treatment is a trunk injection of ememactin benzoate. This
treatment is recommended every two years, throughout the life of the tree. Current research
suggests trunk injections of ememactin benzoate have up to a 99% success rate for trees that
have not been infested or in decline. Current pricing for treatment is —$6.00 per diameter inch
per tree. Data from the tree inventory suggests there are —400 trees that may be candidates for
treatment given size, location and health. The cost for treatment could be —$50,000 every two
years for the next 10-20 years. Treatment does not eliminate the removal cost, but may delay
the expense of removal.
All chemical product labels warn of the potential effects they can have on pollinators and other
organisms. The Iowa State Extension Office PM2084 and ENT45 discusses application and
procedure to minimize effects. The current chemical use policy for the City of Iowa City limits
application to invasive and noxious plant material. Treating trees with an insecticide will require
an adjustment to the City's Chemical Use policy, which is an administrative policy from the City
Manager's Office.
Recommendation
The loss of any tree, especially mature trees that are a defining characteristic of a
neighborhood, is devastating. Staff is sensitive to this reality and understand it has a great
impact on the community. Removing mature trees is a difficult decision to make each time.
August 30, 2018

Staff recommendation regarding chemical treatment is not limited to Ash Trees. Although Ash
Trees are the current focus, there are several other tree diseases and infestation that will likely
have a similar impact of other varieties in the future. Chemical treatment may prolong the life of
a tree but staff believes this is only a temporary stop-gap measure. Most will still need to be
removed eventually regardless of treatment. Staff believes the best use of City resources is to
continue a long-term strategy of tree removal at a pace that mirrors the public safety risk. This
maintains a focus on heavy replanting with diverse species.
We will investigate neighborhood infill planting programs through the upcoming budget process
to help anticipate and mitigate the impacts.
Staff looks forward to discussing this issue with the City Council at the September 4'h, 2018
work session. In order to help provide a broader perspective to the issue, staff has also invited
Mike Kintner, Entomologist and EAB and Gypsy Moth Outreach & Regulatory Coordinator with
the Iowa Department of Land Stewardship, and Mark Vitosh, Iowa DNR District Forester to
attend the work session and offer their thoughts and answer questions.

Fellow Councilors:
During council time, I will be seeking your support for a work session on additional remedial measures relating to Kinnick
Property. I am very concerned about issues with storm water adjacent to the property. I also believe that we should
consider additional measures to ensure that appropriate procedural and substantive safeguards are in place to ensure
that another Kinnick type structure does not happen again in our community.

Johnson County Social Services Mobility Coordinator
FY 2018
July 15',2017—June 30th, 2018
History and Purpose:
Social Services Mobility Coordinator position started on March 20th, 2017. Funding supports for this position include Job
Access Reverse Commute federal funding provided through the Iowa DOT,Johnson County, City of Iowa City, and City
of Coralville. The Social Services Mobility Coordinator serves as the County's single point of contact for transportation
referrals, education and community outreach. This position aims to increase awareness of public transit and expand
potential ridership.Also,strives to improve overall mobility for elderly, low-income persons, and persons with
disabilities.
Accomplishments:
Housed in the Johnson County Social Services Department in the Health and Human Services building, anyone is able to
utilize the services of the Social Services Mobility Coordinator. Below are on-going program initiatives and services that
the position has developed during fiscal year 2018:
• Travel Training: The Coordinator provides travel training,the practice of teaching people how to ride the bus in
individual and group settings.This service targets new riders with specific travel needs who lack the support needed
to learn the system or could benefit from personalized coaching.Underserved populations such as seniors,persons
with disabilities, low-income persons and other special populations such as re-entry group and refugees have been the
focus of this service.During FY 2018 the Coordinator performed the following Travel Training sessions on the bus:
• Iowa City senior from her home to Walmart
• Iowa City refugee from his home to IC Compassion for English classes
• Coralville senior refugee with a disability learning to travel from home to Iowa Workforce Development and
Vocational Rehabilitation in Iowa City
• Collaboration with Goodwill Employment Services working with a Coralville resident with a disability riding
the bus to new employment in Coralville. Trained on the transfer step and the downtown interchange
• Coralville resident with a disability riding the bus from home to Eastdale Plaza and Goodwill Services in
Iowa City
• Trip Planning:The Coordinator offers step by step for individuals looking to get to and from Point A to Point B
using Iowa City Transit, Coralville Transit and Cambus. The Coordinator fulfilled 55 trip plans in FY 2018. Plans
include details on start and stop times,bus routes,bus stops and transfers.
• Targeted Transit EducationaVlnstructional Guides: Multiple trip planning requests to the same locations helped
the Coordinator identify the opportunity to collaborate with local community service organizations and develop
resources explaining how to access these hot spots by public transit. From there, specified travel guides were created
by the Coordinator.The guides contain visual and written instructions and incorporate trip planning, maps,bus routes,
bus stops,and Bongo.Transit guides were created for:
• Services on Gilbert Court,accessing Johnson County Crisis Center,Free Lunch Program, Salvation Army and
more
• Riding the bus from Hope House Re-Entry program to the Abbe Center and Prelude Behavioral Services for
walk-in hours
• Riding the bus from DVIP to the Crisis Center and Souper Bowl event
• Ecumenical Towers to Social Security Office,Towncrest Area and Iowa City Marketplace
• Coralville Senior Residences to the Coral Ridge Mall and Senior Center
• Chatham Oaks to R Place Peer Center
• Transportation Referrals and Resources: The Coordinator responds to transportation related inquires via in-person
visits,drop-ins, email,and phone. Provides information and referrals on public transportation options,criteria for
public transit discounts,where to buy bus passes,which bus passes/fares work between each systems,Non-
Emergency Medical Transportation,where to get bus pass assistance,intercity busing(Trailways,Megabus),
specialized accessible transportation, non-profit volunteer programs such as Elder Services RSVP,American Cancer
Society. Also explains how to use Bongo,Corridor Rides rideshare and vanpool,and ridesharing smartphone
applications(Uber/Lyft). The Coordinator also maintains online resources on www.johnson-county.com/mobility.
• On Site Trainings--How to Ride and Public Transportation in Johnson County: Presentation training the
audience how to ride the bus and educating them on public transportation options in Johnson County. Trainings were
facilitated with the following groups in FY 2018:
• Coralville Seniors: Primetime Potluck
• Ecumenical Towers
• IC Compassion English Learner's Class
• Coralville Senior Residences
• IC Compassion Women's Refugee Group
• Crisis Center Food Bank Volunteers
• YES! Youth Empowerment to Serve Summer Employment Skills Training
• Goodwill and Vocational Rehabilitation Summer STEM Program for High School Students with Disabilities
• Shelter House Outreach:The Coordinator started open office hours at Shelter House twice each month for 2 hours
on January 24th,2018 (midway through FY 2018).This opportunity proved to be a successful way to connect with
individuals experiencing homelessness.The Coordinator finished the rest of the FY connecting with a total of 28
individuals staying at Shelter House.Conversations were commonly about how to apply for public transit discounts
such as the Disabled Bus Pass and Senior Passes,employment options on/near the bus route or how to get to medical
appointments. A lot of the time residents of Shelter House are new to Johnson County and the Coordinator will
explain how the bus system works, fare structure and transfers.
• Transportation Forum: Car Free and Carefree:Maintaining your Independence by utilizing local transportation
options. The Coordinator co-facilitated the forum with Johnson County Livable Community Transportation Action
Team during Older Adults Month on May 8th 2018. The forum offered a panel consisting of the Coordinator, local
transit directors and elected officials who all had an opportunity to talk about their services and transportation options
for seniors. Questions and discussion topics from the audience occurred as well. Filmed by Coral Vision with 29
attendees.

Previous Goals Progress:
• Marketing and Training Videos: Discussions with Iowa City—City Channel 4,Jack Brooks, identified a need
for introducing the Mobility Coordinator as a resource during the upcoming Transit Study. Any production is still
in the phases of development.
• Bus Outing Excursions: During FY 2018 the coordinator implemented a on the bus training with a group of
newly resettled refugees from the Lakeside area to Walmart in Iowa City. One of the participants of the group
spoke English and was able to translate information in French to the new English speakers.The group of women
and children enjoyed themselves and remarked that it was a great opportunity for them to visualize the different
points of interest on the route and see the downtown interchange transfer location from a firsthand point of view.
The group also got to practice asking for a transfer and pulling the request a stop cord.A 10—Ride pass incentive
was provide to each of the women for completely the training.
Future Goals:
• Translate Educational Materials: Translate transit educational materials into languages appropriate for Johnson
County non-English speaking populations to ensure their access to public transit information.
• GIS Project"Ride.Relax.Repeat.": Collaborate with University of Iowa Student, Erich Martin, on a GIS
Project,tentatively called"Ride. Relax. Repeat." The goal of the project is to integrate bus routes with landmarks
or points of interest on print friendly materials usable for the public. The project will serve as a tool for anyone
accessing the community by public transit. The idea to have the maps printable to serve as visual guide for
individuals without intemet or technology to be able to determine where critical services and employment are
located on the bus routes.
• SEATS Rural Ridership/Special Projects Funding: Collaborate with Johnson County SEATS to increase
ridership in rural areas. Consider applying for Iowa DOT State Transit Assistance: Special Project Funding.

Karr, Quentin Pitzen, Lee Shope
MEMBERS ABSENT: Gosia Clore, Sharon DeGraw, Cecile Kuenzli
STAFF PRESENT: Jessica Bristow
OTHERS PRESENT: Kevin Hanick
RECOMMENDATIONS TO COUNCIL: (become effective only after separate Council action)
CALL TO ORDER: Chairperson Boyd called the meeting to order at 5:30 p.m.
PUBLIC DISCUSSION OF ANYTHING NOT ON THE AGENDA:
There was none.
CERTIFICATE OF APPROPRIATENESS - CONSENT AGENDA:
706 East College Street.
Bristow said there did not need to be discussion for this item. She showed a photograph of the
property. Bristow said the consent agenda works by having Commission members read the
material and then vote on a motion. She asked if anyone had questions about the project.
Burford asked what the window was for. Bristow said staff doesn't really know. She said there
is one on each side. Bristow said the window is metal-framed. She said staff doesn't know
when it was installed, although it is not in the historic photograph, which has a wide-ranging
date possibility of 1920 through 1966.
Pitzen asked if the window was operable. Bristow responded that it once was operable but is
not any longer.
Burford said she was not present for the original discussion of the changes to this building. She
asked if anything was said about restoring the palladium window and the fenestration details.
Bristow said that with the overall project, the owner removed all of the synthetic siding. She
said that some of the trim details above the palladium window will be put back. Bristow said the
owner is being very faithful to what he sees as the scars of the removed trim that are on the
house, and that is being replaced.
MOTION: Builta moved to approve a certificate of appropriateness for the casement
window removal at 706 East College Street as presented in the application. Karr
seconded the motion. The motion carried on a vote of 7-0 (Clore, DeGraw, and Kuenzli
absent).
HISTORIC PRESERVATION COMMISSION
August 9, 2018
Page 2 of 11
CERTIFICATE OF APPROPRIATENESS:
1154 East Court Street. •
Bristow said this property is in the Longfellow Historic District. She said the Commission has
never reviewed any work for this property. Bristow said this house is a foursquare that is
covered in what is probably asbestos siding.
Bristow stated that there are multiple parts to this project. She said that the first part involves
the front step condition and treatment. Bristow said one can see that the front steps were pre-
cast concrete steps that were just put in, so they are not the original stairs for this property at all.
Bristow said, given that this is a wooden porch, it may have had a wooden set of stairs. She
said that there are some potential examples of similar houses and similar piers with concrete
stairs and block sidewalls that match the piers on the house.
Bristow showed an example from Ronalds Street. She pointed out that even though these are
concrete and block, they do deteriorate. Bristow said it is not known what was originally on the
Court Street house, because these do deteriorate as well. Bristow said it is not something that
can be determined by the Sanborn maps, as they do not show the steps or stoops.
Bristow showed an example from Iowa Avenue. She said that they all follow the similar idea
where the sidewalls come off flush with the inside of the piers. Bristow said that is what is
proposed.
Bristow pointed out the new drawings to Commission members. She said they were just
updated with a little bit thicker sidewalls - more constructible. Bristow said that the slide images
also show the new drawings, as the old ones were in the packet.
Bristow said this therefore involves two steps of a sidewall with limestone caps and a black
metal handrail that will be mounted to the steps themselves. She said staff finds this to be an
acceptable way to put on new steps that would be more compatible than the existing, non-
historic stairs.
Bristow said that another element of the project involves replacement of the rear stairs as well,
with a handrail that meets the guidelines. She said that the bigger part of this, on the back, is
converting the sleeping porch, which appears to be original, on the second floor to a bathroom,
which would mean enclosing it a little bit more than it already is. Bristow said that it is an
enclosed part of the house. She said that it probably had an open porch below it, based on
some of the siding, but it is all enclosed now.
Bristow said that the plan is to retain the central windows in the sleeping porch but to replace
the glass with an obscure glass. She said that the side windows next to that and right around
the corner would be replaced with slightly smaller windows. Bristow said it fits within the scaling
of the original windows so that it accommodates the bathroom fixtures.
Bristow said that the windows that are closer to the house though would be removed, partly
because there is a shower in one corner and to balance it out. She said that since those are
against the house anyway, they will not be very visible, so it is an acceptable compromise to
HISTORIC PRESERVATION COMMISSION
August 9, 2018
Page 3 of 11
make for the bathroom. She said one would still have a lot of the language of the sleeping
porch. Bristow said that below the bead board there are three little openings across the bottom
from where the original porch was for drainage on the original open porch. Then below that
there is some of the newer siding that is not an historic siding. She said that the plan would put
a band board across the bottom of the beadboard to clarify that condition a little bit more.
Bristow stated that the siding would continue to be bead board like it is now, so this would keep
a lot of the same language that is going on with this property.
Bristow showed what the exterior would look like on one side. She showed where the window
next to the house would be removed and the window at the corner would be a shorter window.
Bristow showed the rear elevation of the house.
Bristow said that window product information still needs to be approved, so she recommends
including that in the motion. She said staff finds that all of the parts of this project are
appropriate.
Hanick, the owner of the property, referred to the rear elevation of the house. He said he has
looked into what windows would be available, including a wood, double hung window for the
larger, center ones. Hanick said he thinks he can get it so that just the bottom is obscure and
the top would be clear, which he thinks would be better for the interior. He said then the same
window would be partly obscure and partly clear.
Bristow said that brings up the question of whether or not those are the original windows reused
or if the owner plans to replace them. Hanick said they would be replaced. He said that the
current windows are rotten. Bristow said she was unsure if, since this was a screened porch
originally, they were actually windows or not. She said this house has probably not had much
maintenance on it for a long time. Hanick agreed.
Hanick said he thinks the new front porch drawing where the sidewall is thickened up will look a
lot nicer. He said there will be a.limestone cap on that. Hanick said he found a company in
Indiana that makes what they are calling authentic, rock-faced block, which he'll use. He said
he hopes the colors will be compatible.
Hanick said the ones on the foundation are slightly different. He said he thinks the new block
will be more like those, and they will weather together over time and shouldn't be a problem.
Bristow said that some people doing this type of project have actually just stained the new block
to match, sometimes just a very slight gray stain.
Hanick said the only other thing that is not on the application involves an old coal chute that
currently exists on the west side of the house along the driveway. He said there is currently a
piece of plywood over that. Hanick said he would like to order enough block to fill that in to
make it a consistent rock face foundation.
Bristow said that could be added to the application. She said that is the kind of thing the
Commission would find acceptable, especially if there is not an original metal chute cover or
anything to put in its place. Bristow said that typically one likes to see holes like that repaired
with the block toothed in.
Karr referred to the window elevation for the porch. He asked about the plan to have the top
sash be clear and the bottom will be obscure. Hanick said that more natural light would be
HISTORIC PRESERVATION COMMISSION
August 9, 2018
Page 4 of 11
better than having it obscure all the way around, and this is for the back yard. He said he would
like to do that if possible.
Hanick said that there is a little 1960s addition on the main level. He said there is one rotten
window there that he would like to replace with the same thing that is there. Bristow said that
should be part of the application as well.
Bristow said it is up to the Commission whether it wants to add the coal chute and/or the other
window to the motion. She said that staff would find that appropriate. Bristow said that the
1960s addition probably has casement windows right now. She said that if all of the windows
were going to be replaced, she would say that using something that fit the house would be
better. Bristow stated that for only one window, making it match the others would be an
appropriate way to go. She said that if the Commission did not want to add these items to the
motion, they could be addressed as minor reviews to be looked at by staff.
MOTION: Agran moved to approve a certificate of appropriateness for the project at 1154
East Court Street as presented in the application with the following conditions: window
product information for the sleeping porch renovation to be approved by staff; the repair
of the coal chute as discussed at this meeting to be approved by staff; and the repair to
the casement window in the 1960s addition, since it is not for all four windows, to be
approved by staff. Karr seconded the motion. The motion carried on a vote of 7-0 (Clore,
DeGraw, and Kuenzli absentl.
REPORT ON CERTIFICATES ISSUED BY CHAIR AND STAFF:
Certificate of No Material Effect- Chair and Staff Review.
1424 Center Avenue.
Bristow said this project involves the replacement of shingles on a non-contributing property in
the Longfellow Historic District.
622 North Van Buren Street.
Bristow said this project involves the repair of column bases, storm window repair, and a little bit
of trim reconstruction.
1036 Woodlawn Avenue.
Bristow said the carriage house at this address was damaged by a tornado, and most of the
foundation walls were replaced at that point in time. She said that now, because of drainage
and a collapsing wall issue on the south face, that wall is being replaced as well, as is the
concrete apron that goes into the carriage house.
423 Ronalds Street.
Bristow said this house has an addition on the back with casement windows that open out that
are being repaired and with screen windows that open in. She said the windows had water and
air leaking for awhile.
HISTORIC PRESERVATION COMMISSION
August 9, 2018
Page 5of11
Bristow said that a conference she attended provided a sample of information of the Indow
product, which is basically a storm window that is flexible so that one can squeeze it in and put it
there and squeeze it out as well. She said that it does not have any fasteners and does not do
anything to the window opening itself.
Bristow said the owner was having difficulty finding a solution for these windows, because she
did not want to put any holes into the frame. Bristow said the owner found these, and so that
storm window has been approved as part of the preservation fund for this particular house. She
said the new product does not seem to be very expensive, so this will be a kind of test as to how
they work.
427 North Dodge Street.
Bristow said this house has a carport that had plywood siding all the way to the ground that was
wicking up moisture. She said that was permanently removed, and a couple of structural
members were replaced.
701 East College Street.
Bristow said this project is to replace the wood shingles on the house.
Minor Review- Staff Review.
15 North Johnson Street.
Bristow said the site stairs on this building are being replaced to match the existing, and
hopefully the railing will be replaced with a black metal rail instead of the wood rail. She said
that will be done if the wood cannot be reused.
737 Grant Street.
Bristow said there is an attic window in the front of this bungalow, and the window on the back
was enlarged and did not match. She said the owners wanted to replace it and remove the
through-wall air conditioner next to it. Bristow said there will be some stucco repair. She said
the owners wanted to replace the window with that size but found the original window in the
attic, so they are just going to reinstall the original window.
1049 Woodlawn Avenue.
Bristow said this project consists of replacing the front wood steps and replacing the handrail
with a metal handrail.
Intermediate Review- Chair and Staff Review.
833 Rundell Street.
Bristow said that because of budgetary constraints, the screened-in porch on the back is being
replaced with a simple entry stoop and entry canopy with stairs. She included the drawing
which is marked-up, because there were some other changes that are under the Commission's
HISTORIC PRESERVATION COMMISSION
August 9, 2018
Page 6 of 11
purview, such as making the dormer the same height as the roof, which is not appropriate so it
will be lower like it is supposed to be.
727 Dearborn Street.
Bristow stated that this house is not really contributing, because it has been remodeled. She
said it is unknown what is original on this house and what is not.
Bristow said the Commission approved an addition on the back, and the approval was
conditioned on matching the foundation material, rock-faced concrete block. She said the
owners came back with asking to just use smooth, concrete block. Bristow said that typically,
one wants this to match, but it is also a factor to be able to tell what is original and what is not.
She said that chair and staff decided that using the smooth concrete would be fine in this
instance, because then it would be forever known that this is an addition.
Bristow said that as the owners got into the project, they removed the aluminum siding on the
house and were able to get in and realized that most of the windows had been replaced and all
of the sills had been cut down. She said that hopefully this will add some general clarity to this
house.
Karr asked about the application regarding the flexible from the inside storm windows. Bristow
confirmed that storm windows, even on the outside, do not require Commission approval. They
were reviewed because the project was using the Historic Preservation Fund.
CONSIDERATION OF MINUTES FOR JULY 12, 2018:
MOTION: Agran moved to approve the minutes of the Historic Preservation Commission's July
12, 2018 meeting, as written. Shope seconded the motion. The motion carried on a vote of 7-0
(Clore, DeGraw, and Kuenzii absent).
COMMISSION INFORMATION AND DISCUSSION:
Commissioner vacancies.
Bristow stated that the City Council has asked that staff and the Communications Department
work together to try to recruit someone for the Jefferson Street District, which staff has always
thought might be an empty seat, and for the East College Street Historic District. She asked
Commission members who know someone who resides in either district to find out if he/she
would be interested in serving on the Commission.
Bristow said the City will be putting out a mailing shortly that will go directly to every resident.
She said that a Commission member must be a resident of the district; someone who is an
owner of property in the district but does not live in the district would not be eligible.
727 North Lucas Street Garage Demolition.
Bristow said this is not coming before the Commission, because there is not currently a plan to
build a new garage. She said that the building official determined that the garage had to come
down. Bristow said she just wanted to let the Commission know about the situation.

Iowa City-Hosted Preserve Iowa Summit Postponement.
Bristow said there was a lot of debate last calendar year about the Preserve Iowa Summit and
holding off until 2020 or holding off until 2021. She said the decision was made to have it in
2020, and staff was starting to compile information to apply for the grant that is due September
1 to start planning for that.
Bristow said that department directors and upper level staff decided that this should be
postponed, because of the fact that it will take more planning than just the Commission and
herself can complete. She said it will take assistance from some of the other urban planners,
who are all very new, so that the decision was made to postpone this.
Bristow said the State was caught off guard a little bit, because of the late notice to them as
well. She said this is being worked through, and staff will try to do this again at the next
available opportunity. Bristow said it may be 2021, although she assumes the State may try
again for a location in Western Iowa. She said staff will coordinate with the State on when the
next available time will be.
Iowa City Public Library Historical Iowa City Newspapers Website.
Boyd said that the Iowa City Public Library added a really great feature - a searchable database
of all the Iowa City newspapers from the 1870s to 1925. He said it is searchable by words and
phrases and is a good resource for people looking into older homes.
Boyd referred to the two pages he found that were worthwhile for the Commission to know
about. He said that part of the Commission's job is to help people understand the shared
history of Iowa City. Boyd said the Library does a lot of that work also, and he wanted to make
sure people knew about the resource.
Clinton Street and Railroad Depot Historic District Update.
Boyd said that some of the City staff would like this to go to the City Council very soon. He said
that the Commission moved kind of quickly on this once the report came back. Boyd said that
often, for something like this, the proposed district boundary would go to the State Historic
Preservation Office, which would review the boundary because it would also be a boundary for
a National Register nomination.
Bristow said that typically, not for every district but for many of the districts, they have been
National Register districts before being local districts. She said that means that the National
Register nomination goes to the State for review prior to the local process.
Boyd said the State had reviewed a previous iteration of this district and said that it would be
acceptable but has not had a chance to review the current district. He said that being on the
National Register is an additional benefit to the property owners. Boyd said that what staff and
the Commission wanted to do was to get feedback from the State Historic Preservation
Commission Office (SHPO) to make sure the proposed boundary would also be an acceptable
boundary for the National Historic Register.
Bristow said there is actually a grant to do that revised boundary National Register nomination
for this district. She said the consultants are working on creating their contract now so that

revised nomination will probably be reviewed by the State in December. Bristow said it won't go
to their review committee until June, but they will review a draft in December.
Boyd said then there would be some sense and feedback as to whether this is on the right track.
He said he would recommend that the Commission hold off on moving this nomination forward
to the City Council. Boyd said it is his understanding that the only way to do that is to withdraw
the nomination and then have it go through the process again.
Boyd said the Commission is trying to be responsive to making sure the owners have maximum
benefits and making sure the Commission is being thoughtful to the concerns raised before the
Planning and Zoning Commission. He said the timing of taking this to the City Council
sometime in the late fall or winter might be better. Boyd said there is a lot going on at the City
Council right now. He said there will be a full City Council on October 6.
Boyd said this is being done because of the boundary issue. He said he thinks the Commission
should try to be sensitive to any concerns and work out as many of them as possible before
moving this to the City Council.
Boyd said that the upcoming grant will help move the potential district to the National Register.
He said that SHPO will kind of weigh in on the front end as to whether this is on the right track.
Boyd said that if SHPO says this is headed the right way, by the time it gets to City Council, the
Commission will be able to say that this is eligible to be on the National Register. He said the
Commission is really trying to tie those two things together, because there has been confusion
about why they are separate.
Burford asked when the Planning and Zoning Commission discussed this. Bristow said she
thought it happened in June or July.
Karr said that in this situation there is a property owner who owns a large portion of the
properties that is against this and asked if there is still a moratorium. Boyd replied that there is
not one currently. He said the moratorium starts when the City Council sets the public hearing.
Boyd said that what staff and the Commission are trying to do is to take care of this before that
starts. He said it would be communicated to the property owner what the timeline is and what
the Commission is trying to do. Boyd said it should also be made clear that the maximum
number of benefits are available to him, which would include a National Register nomination.
Karr said the downside, if one were in favor of having this as a district, is that there would be
several months with the possibility that buildings could be altered and changes could be made.
Boyd confirmed this. He said that all of the properties appear to be rented at the moment.
Bristow said that if the nomination is withdrawn, the Commission will have to start over. She
said there would be an owner meeting, an Historic Preservation Commission meeting, and a
Planning and Zoning Commission meeting again. Bristow said that the Commission could start
the process as soon as comments are received from SHPO.
2018 National Alliance of Preservation Commissions Forum - Des Moines.
Boyd said he and Bristow both went to this conference in Des Moines a few weeks ago.

Boyd discussed a presentation by Karcher, which is actually a power washing company. He
said that the company cleans cultural resources for free. Boyd said the company has done a lot
of big projects and is now working on more and smaller projects to try to move into more places.
They clean historic stone with steam and a low-pressure sprayer. The steam kills organic
materials like moss and lichens.
Boyd said he e-mailed the University Facilities Department and Geoff Fruin to share this
information, as well as Juli Seydell-Johnson, the Parks and Recreation Director. He said this
may or may not be an opportunity, but he thought it was very interesting and wanted to share
the information.
Boyd said the City of Ottumwa has; through a public/private partnership between the City,
Wapello County, and private development; really restored a lot of its historic storefronts. He
said the work done there is really driving a lot in the community in terms of engaging in
downtown, a lot of community events, pop-up stores - some of which have become permanent
stores, etc. Boyd said they have added a lot of housing diversity to the community. He said it
was a great example of how historic preservation can help both build community and help with
economic development in a community like Ottumwa.
Boyd discussed the Dubuque Heart Program. He said that the non-profit Four Mounds in
Dubuque, through the Heart Program, works with the Dubuque School District to identify mostly
high-risk students. Boyd said they attend a half day of learning techniques that are not taught
as much anymore to use on older homes, such as window restoration and plaster repair.
Boyd said they have been doing this long enough that some graduates of the program have
taken the knowledge and have businesses to provide these types of services. He said that the
neighborhood north of downtown has been historically troubled, but this program has taken
sometimes a whole block at once and rehabilitated it. Boyd said that a lot of these students in
the program are residents of the neighborhood, and this is reshaping the neighborhood and
reshaping the lives of these people.
Boyd said that at the conference there was a lot of discussion with other commission members
and people from around the country about the work they are doing to make sure historic
properties are celebrated. He said that Iowa City's Historic Preservation Commission is doing
that with the grant for the Tate Arms Building and the Iowa Federation Home.
Boyd said that some of the recognition consists of plaques, some is social-media driven, and
some of it uses mapping software. He said it involves the democratization of historic
preservation in that it gives people somewhere to share their own stories about places that add
to a richer history.
Bristow agreed that the mapping is an interesting concept. She discussed the Lucas Farms
Neighborhood, where neighbors are very active and engaged. Bristow said that in some cases,
we have historic resources that we know nothing about. She said the first step for that is a kind
of windshield survey of what is there, what the ages are of the houses, and what the styles are.
Bristow said that volunteers could do that type of work, with mapping applications that can be
done on a phone.

Bristow said there is also potential for tying together sustainability and historic preservation.
She said they work together well, and adding a little bit of sustainability to each section of the
guidelines could help a lot with that.
Bristow said there are also some opportunities for education. She said there could be sessions
for design reviews and other things. Boyd said that one city appointed a high school student
who was interested in historic preservation to its commission.
Bristow stated that there is a potential for an emergency project on a local landmark building
that is downtown. She said that it is a signage issue, which comes to the Commission
automatically. Bristow asked if Commission members would be able to attend a special
meeting if it is called for this project.
Boyd said the Commission is technically scheduled to potentially meet on the fourth Thursdays
of the month but has not needed to historically. He said this business is a downtown historic
landmark, and the Commission should try to be as responsive as possible. Bristow agreed but
added that an application has to be submitted at least 24 hours before a meeting to allow time
for it to be reviewed and to get it on the agenda.
Bristow said she will give the date of the 23rd as a potential option and let the applicant know
that consideration will be based on being able to have a scheduled meeting.
Agran said he has been asked about the status of the downtown survey and about whether
facade funds could be available from the City. Bristow said there have been some delays. She
said that the Commission's project creates a multi-property document, which is the long story of
downtown. Bristow said that it will create a report and site inventory forms.
Bristow said that part of the story is the City's urban renewal. She said this was submitted to the
State for comments, but it turns out that the State will not even be able to review it until October
3. Bristow said that the City has therefore pulled back and decided not to do that.
Bristow said that now it's a matter of figuring out the timing for a public meeting and having a
review of it coming to the Commission. She said the Commission will read the report and
review the documents to some degree. Bristow said then the Commission will make some
determination on a National Register as soon as possible, partly because that makes funding
available to people, although that process takes at least a year.
Bristow said then it would be up to the Commission or a Commission subcommittee to
determine local district designation and the timing for that. She said that it would probably
happen soon but likely after national designation process has begun.
Bristow said there is a potential for the report to come to the Commission for the September
meeting, but it may not be until October. She said the public meeting will also happen in this
time period from early September through mid-October.
