Summary
Ordinance 05-23 was postponed at the February 27, 2023 City Council meeting following additional
direction on the accompanying resolution for the Neighborhood Design Guidelines. As part of the
discussion of the proposed Code amendments, one item was raised for further review regarding
tree spaces. Follow up on this inquiry is provided below.
Update
At first reading on February 13, 2023, Council requested that Section 153.052(B)(3)(d) include two
changes in section 7: remove the word “unbuildable” and spell out NDG. These have been
addressed and are reflected in revised materials.
At second reading on February 27, 2023, Council inquired about increasing tree setback distances
to the sidewalk in the related Code section (153.134(A)(1)(a-g). Planning and Forestry staff
discussed options to address distance requirements and recommend a more holistic approach be
taken with a future Code amendment. Staff agrees with widening the tree lawn to a minimum of
eight feet, providing a four-foot distance from the trunk on either side, to each curb and sidewalk,
as a best-case approach. Spacing should vary depending on the size and species of the tree as
well. Staff has identified there could be impacts to public right-of-way widths as a result. Staff
recommends additional time to understand the impacts of a proposed amendment and will take
on this request as a separate project.
Amendments
The proposed amendments to the City of Dublin’s Subdivision and Zoning Code Sections address
neighborhood design as part of the Neighborhood Design Guidelines effort. The draft Code
Amendments address substantive items along with changes to legally connect the Guidelines to the
Code, specifically in areas of intent and processing. Staff also took the opportunity to address minor
clean-up items. The draft Code amendments are attached, but include amendments to Code
Sections 152.002, 152.086, 153.050, 153.052, 153.054, 153.071, 153.134, and 153.190.
Planning and Zoning Commission Recommendation
On the January 19, 2023, the Planning and Zoning Commission recommended approval of the
Code Amendments.
Recommendation to Council
Council approval of Ordinance 05-23.

Draft Code Amendments – March 27, 2023
§152.002 PLANNED UNIT DEVELOPMENT. An area of land, zoned under § 153.056, in
which a variety of housing types and/or related commercial and industrial facilities are clustered
in an imaginative preplanned fashion to permit the development of the land in an orderly,
coordinated and comprehensive manner by preserving the natural quality and beauty of the
land and providing a more livable housing environment. To foster creative planning, more
flexible standards for streets, drainage, setbacks, lot sizes, etc. are provided within these
subdivision regulations that are designed to meet the kinds of design conditions that exist
within PUDs and which are examined and reviewed with §§ 153.050 through 153.058. The
Planned Unit Development is for the purpose of conserving land through more efficient
allocation of private lots, multi-family dwelling units, common grounds and nonresidential uses,
promoting greater efficiency in providing public and utility services, and securing the benefits of
new techniques of community development and renewal. Within a residential Planned Unit
Development district or zone, the Zoning Ordinance regulations need not be uniform, but may
vary in order to promote the public health, safety and morals, and the other purposes, as
specifically identified in the Neighborhood Design Guidelines and other related documents.
Adopted regulations may require developers to obtain conditional or final certification of
compliance with the zoning ordinance at specified stages of development. As used
herein, PLANNED UNIT DEVELOPMENT means a development which is planned to integrate
residential use with collateral uses, and in which lot size, set-back lines, yard areas and dwelling
types may be varied and modified to achieve particular design objectives and make provision
for open spaces, common areas, utilities, public improvements and collateral nonresidential
uses.
152.086 Open Space Requirements. (A) Land dedication. The basic land dedication
requirement shall be that 2% of the total gross site area, plus .03 acres per dwelling unit
proposed, shall be set aside as open space except that in no case shall the open space
requirement exceed 25% of total gross site area. Such area shall constitute ground suitable for
public parks and playground facilities as reviewed and approved by the Planning and Zoning
Commission. For residential PUDs, location and quality of open space is addressed in the
Neighborhood Design Guidelines.
153.050(A) Purpose. The Planned Unit District (PUD) regulations are based on the premise
that the ultimate quality of a built environment or development proposal is determined not only
by the type, character and allocation of land uses but also by the way in which such land uses
are executed. In many cases, the subdivision regulations and standard zoning district
regulations and procedures do not adequately regulate the design of buildings or enable the
range of uses in a single zoning district that are appropriate in the City. The City has adopted
Neighborhood Design Guidelines to ensure that these higher standards are met.
§153.052(B)(3)(d): Open space. Adequate open spaces shall be integrated throughout the
development to meet the objectives of the Community Plan and shall comply with the open
2
space requirements set forth in Chapter 152, Subdivision Regulations. PUDs that include
residential uses shall include open space that is located and designed as follows:
1. Open space shall be sufficiently aggregated to create large useable areas of planned open
space.
2. Open space shall conserve significant natural features within the PUD to the extent
practicable.
3. Open space shall provide a scenic natural environment along existing public streets
characterized by large building setbacks that enable the preservation of natural features.
4. All open space shall be easily accessible to residents of the PUD.
5. Where possible, open space areas shall be connected with open space areas on abutting
parcels, and wherever possible, by open space corridors
6. Stormwater features shall not count as open space, unless they achieve a superior,
interactive design as outlined in the Neighborhood Design Guidelines.
7. Easements and required perimeter setbacks shall not count toward open space unless they
are integrated into the overall Open Space Framework pursuant to the Neighborhood
Design Guidelines.
§153.054(A): Contents of concept plan application. It is the intent of these regulations that the
concept plan shall generally indicate overall design of the proposed project, including
conformance with the Neighborhood Design Guidelines for residential projects. Information
submitted should be comprehensive enough to enable the staff to understand the existing site
and concept for the proposed development. The applicant shall submit a number of copies as
determined by the Director of Planning. The information submitted should include the following:
§153.054(B): Contents of preliminary development plan application. The application shall
include the maps, plans, and supplementary documentation itemized below and as indicated in
the Neighborhood Design Guidelines for residential projects. The applicant shall submit a
number of copies as determined by the Director of Planning. The information submitted should
include the following:
§153.054(C): Contents of final development plan application. The application shall include the
maps, plans, designs and supplementary documents itemized below, and as indicated in the
Neighborhood Design Guidelines for residential projects. Copies of the maps, plans, designs and
supplementary documents shall be submitted. Final development plans are intended to be
detailed refinements for development and, as such, shall be accurate, detailed representations
of the total aspects of the approved preliminary development plan. The applicant shall submit a
number of copies as determined by the Director of Planning. The information submitted shall
include the following:
§153.071(4)(e): Unless otherwise required in an approved Planned Unit Development,
structures, parking, driveways, vehicular use areas, service areas, pedestrian areas, and other
hard-surfaces or paved areas may cover more than 45% of the total lot area within a residential
PUD District with design following the Neighborhood Design Guidelines.
3
§153.134(A)(1)(a-f): Requirements. It shall be required that all subdividers or developers
plant trees along public streets of their developments in such a manner, type, quantity and
location as approved by the Planning and Zoning Commission and as defined by the following
conditions, and that any undeveloped street or existing street with undeveloped frontage shall
conform to these requirements at the time of the development. Final tree locations may be
adjusted by the City as unusual conditions may warrant.
(a) The tree to be planted shall be an approved street tree as listed in Appendix
E (Approved Street Trees for Dublin, Ohio).
(b) The minimum spacing between this and other trees shall be 40 feet for large trees,
30 feet for medium trees and 20 feet for small trees. See definition below.
(c) The maximum spacing between trees shall be 45 feet for large trees, 35 feet
for medium trees, and 25 feet for small trees. Spacing may be adjusted for
columnar trees, as approved by City Forestry Division.
(d) Size and spacing of street trees shall be designed to emphasize neighborhood
individuality, highlight the importance of intersections and pedestrian facilities, and
compliment the size and massing of surrounding architecture as noted in the
Neighborhood Design Guidelines.
(e) The minimum distance between the tree and the edge of the street shall be two
and one-half feet for a large tree, two feet for a medium tree and one and one-
half feet for a small tree. In areas where a sidewalk exists or is proposed, the
minimum distance between the tree trunk and both the edge of the street and the
sidewalks shall be two feet for a large tree, two feet for a medium tree and one
and one-half feet for a small tree.
(f) The tree location shall be at least 20 feet from street intersections and ten feet
from fire hydrants or utility poles.
(g) A small tree shall be used when planting under or within ten lateral feet of
overhead utility wires. A small or medium tree shall be used when planting within
ten to 20 lateral feet of overhead utility wires.
§153.190(A): Residential appearance. The following findings warrant the need for exterior
appearance requirements for residential development for standard zone districts. PUDs are
required to use the Neighborhood Design Guidelines.
§153.190(B)(2): Residential appearance in Planned Unit Development Districts shall be
evaluated according to the Neighborhood Design Guidelines.
§153.190(C)(3): Houses in districts described below are exempt or must comply with these
requirements as follows:
(a) Houses located within a residential Planned Unit Development district approved
after the effective date of this section shall be evaluated according to the
Neighborhood Design Guidelines.

Ordinance 05-23 – Amendments to Code Sections 152.002, 152.086, 153.050,
153.052, 153.054, 153.071, 153.134, and 153.190 to update the residential
Planned Unit Development references to include Neighborhood Design
Guidelines (Case 23-002ADMC).
Summary
Ordinance 05-23 is a request for review and approval of amendments to the City of Dublin’s
Subdivision and Zoning Code Sections to address neighborhood design as part of the
Neighborhood Design Guidelines effort. The accompanying Code Amendments are necessary to
require the changes envisioned by the Guidelines and also to legally connect the Guidelines to
the PUD process.
Background
As presented in the accompanying memo for the Neighborhood Design Guidelines, the project
began in mid-2020 with staff focused on the development of draft Guidelines. Realizing that
related Code Amendments would be necessary, staff introduced the discussion at the December
8, 2022 PZC meeting and confirmed the following amendment topics:
1) Limiting how stormwater ponds count toward required open space;
2) Allowing greater than 45% max lot coverage in residential PUDs;
3) Allowing flexibility in street tree placement, size, rhythms; and
4) Outlining limitation regarding how easements/setbacks are used as open space.
The draft Code amendments were presented to the Commission on January 19, 2023 and the
Commission requested changes to the easement and setback portion of the amendments, which
have been incorporated in the final version.
Zoning Code Amendments
The draft Code Amendments address the items listed above, but also included changes to legally
connect the Guidelines to the Code, specifically in areas of intent and processing. Staff also took
the opportunity to address minor clean up items. The draft Code amendments are attached, but
include amendments to Code Sections 152.002, 152.086, 153.050, 153.052, 153.054, 153.071,
153.134, and 153.190.

Planned Unit Development references to include Neighborhood Design
Guidelines (Case 23-002ADMC).
Summary
Ordinance 05-23 was introduced on February 13, 2023 as a request for review and approval of
amendments to the City of Dublin’s Subdivision and Zoning Code Sections to address
neighborhood design as part of the Neighborhood Design Guidelines effort. As part of this first
reading, City Council requested two minor language changes be made which have been incorporated
into the draft language.
Amendment Updates
At first reading, Council requested that Section 153.052(B)(3)(d) include two changes in section 7:
remove the word “unbuildable” and spell out NDG. These have been addressed and are reflected
in revised redlined and clean Draft Code language.
The draft Code Amendments address substantive items along with changes to legally connect the
Guidelines to the Code, specifically in areas of intent and processing. Staff also took the opportunity
to address minor clean up items. The draft Code amendments are attached, but include
amendments to Code Sections 152.002, 152.086, 153.050, 153.052, 153.054, 153.071,

Staff Presentation
Ms. Holt provided the presentation for Cases 2 and 3 together, as the two cases are linked. She
reviewed the history regarding the Neighborhood Design Standard s effort. Due to concerns related
to the Hamlet on Jerome and Oak Park developments, City Council referred the need for more
specific expectations for PUDs to PZC for study and recommendations. PZC discussed the topic at
their August and October 2020 meetings and defined a holistic intent for the City’s future
residential developments. The needs and intent of the project were discussed further and refined
in subsequent Commission meetings and joint work sessions, and a work plan was established for
developing the recommendations. The Commission reviewed/provided input on preliminary
recommendations in November 2021. Council reviewed/provided input on the preliminary
recommendations at their April 18, 2022 work session and referred the topic to the Community
Development Committee (CDC) for further consideration. Following CDC review and
recommendations, revised guidelines were forwarded to PZC, and on December 8, 2022, the
Commission reviewed the draft Neighborhood Design Guidelines and Code Amendments that had
been developed to achieve the desired PUD character. Final drafts of the documents have been
prepared to include the Commission’s input and are presented tonight for the Commission’s final
review and recommendation to Council.
Ms. Holt stated that Dan Phillabaum, Landplan Studios, LLC has assisted staff in developing these
Guidelines and Code amendments. She explained that the Neighborhood Design Guidelines are
organized into a three-level hierarchy: the broad macro public realm of open spaces and
preservation areas; the micro level public realm of streetscapes as outdoor rooms; and the private
realm of individual lots and the functions of various areas within the lots and lot types. She
reviewed each of the changes that had been made in the Design Guidelines based on the
Commission’s input at their December meeting, including: open space; stormwater features;
street trees; houses fronting open space and public streets; and location of AC units on narrow
lots. Code amendments also are proposed to ensure procedural connection with the new
Guidelines in the introduction, the PUD purpose, and in the open space requirements for PUDs
regarding stormwater, easements and setbacks.
Mr. Fishman stated that his worry is that the proposed language might permit water to be
considered open space.
Ms. Holt responded that it could occur only when the superior and interactive ideals of the
Guidelines were met.
Mr. Fishman responded that developers typically want to minimize the open space they provide.
Because the Commission has stated that open space should be usable and interactive, developers
could try to add a dock or fountain with the argument that they are interactive. The City could
lose significant greenspace, if developers are permitted to replace it with water.
In response to Ms. Call’s query, Ms. Holt described the review process for a PUD application,
including various staff reviews, before it is recommended for PZC consideration. The Commission
Planning and Zoning Commission DRAFT
Meeting Minutes – January 19, 2023
Page 3 of 11
may or may not agree with that recommendation. One of the main goals of the Neighborhood
Design Guidelines is to ensure that excellent design is not precluded by being too prescriptive.
Ms. Call stated that goal is consistent with the intent of a PUD. The Guidelines are not intended
to hinder that, only provide more guidance.
Mr. Fishman stated that he is aware that is the purpose of a PUD, but this Commission will at
some point be comprised of different members. Based on his previous experience with earlier
Commissions, he is aware that some members can be easily persuaded to make concessions. He
likes PUDs but would like to tighten them, rather than making them looser. The trend now is for
higher density, which can work only if there is usable open space. Because PUDs are an
opportunity for developers to get some things they want, they need to be structured sufficiently
tight to ensure the City also obtains what it actually wants.
Ms. Holt continued review of the proposed Code amendments regarding: PUD process steps;
general development standards including lot coverage; street tree requirements; and Section
153.90, Residential Appearance Code, which emphasizes the Residential Appearance Code is for
standard zonings; PUDs are required to follow the Neighborhood Design Guidelines. Staff
recommends the Commission’s approval of both the Guidelines and the Code amendments.
Commission Questions
Ms. Call stated that clarifying the PUD with guidelines will provide opportunity to implement
Council’s vision in future PUD projects. More definition and language have been added to the Code
to assist applicants. Stormwater features were a concern, as they are not really addressed in the
current Code, specifically the coupling of a water feature with a recreational feature or amenity.
The proposed language addresses the qualifications of these features for open space. She
requested Ms. Holt to respond.
Ms. Holt stated that when this item was discussed at the Commission’s December 8 meeting, Mr.
Way suggested the opportunity to use a dry basin as a playing field or passive recreational area.
Staff then began to think about how new stormwater features also could include constructed
wetlands. Individual sites could dictate what kind of stormwater feature might be appropriate.
Ms. Call requested Ms. Holt to comment on three existing examples: in the Glacier Ridge metro
park; the dry basin beside the trail to the North Pool; and the landscaped detention area on the
north side of the North Pool.
Ms. Holt responded that the first example, which is located on the south end of Glacier Ridge Park,
focuses on wildlife. That type of stormwater feature would be an opportunity to preserve/conserve
an existing wetland, integrating seamlessly into a residential neighborhood. It would qualify as
open space. The second example, a dry basin with only an inlet /outlet, would not qualify as open
space; much more would be necessary. It might be possible for a dry basin to be a part of a series
of athletic fields or connected topographically to a playground or other features. The third
example would merit consideration. However, even if beautified, it will be essential to evaluate
dry basins on their merits according to the open space framework plan.
Mr. Fishman stated that he agrees that dry basins can be used recreationally; however, it is
important to keep in mind that different Commissioners will one day sit in these seats. The dry
basins within the Columbus area, for example, are not attractive. Dry basins also require more
maintenance than wet basins, but because HOAs cannot handle that responsibility, the City would
Planning and Zoning Commission DRAFT
Meeting Minutes – January 19, 2023
Page 4 of 11
be asked to provide the maintenance. He would not object to a dry basin counting as open space
if it is an integrated recreational area. This issue would need to be carefully structured to ensure
that the City does not lose usable open space. He understands the tendency of developers to
claim hardship and attempt to call ravines and rocky areas as recreational areas.
Mr. Fishman requested clarification of the Residential Appearance Standards.
Mr. Supelak noted that the Neighborhood Design Guidelines would require PUDs to perform better
than the standards have required.
Mr. Boggs stated that the original intention of the Residential Appearance Standards was to be
applicable to standard zoning. They anticipated the adoption of future guidelines for PUD
applications.
Ms. Harter inquired about the potential maintenance costs of retention ponds/detention basins for
homeowner associations in these PUDs.
Mr. Boggs responded that item, similar to private streets, is a ddressed in the platting process. The
Preliminary Plat would define the maintenance responsibilities. Cost to the City is not a criterion
for this body’s consideration, but it would be considered by City Council in adopting the Final Plat.
Ms. Call stated that in the Commission’s previous review, undulating, meandering pathways were
suggested; however, it appears that the Transportation & Mobility division was not supportive of
that suggestion.
Ms. Holt stated that shared use paths are encouraged to meander and take a scenic route. On the
other hand, sidewalks are intended to provide direct routes to destinations. The functions of
sidewalks and paths are different.
Ms. Call inquired if calculations or standards are employed in defining which it would be, a sidewalk
or shared-use path.
Ms. Holt responded affirmatively.
Mr. Way referred to p. 30, Architectural Composition, Diversity and Materials, in the Guidelines,
which state that, “the architectural design of the residential building should have a timeless quality
that is based on vernacular forms and clad with exterior materials common to central Ohio.” Under
that definition, would it be possible to build a modern, contemporary building in Dublin?
Ms. Holt responded affirmatively. It does not preclude a modern building. There is a large degree
of flexibility; the Guidelines focus more on the quality and form of the materials.
Mr. Way stated that front-facing garages are not prohibited, only required to be 20 feet back from
the front property line. Is there a way to limit the number of front-facing garages in a PUD,
perhaps using a percentage?
Ms. Holt responded that in the Private Realm, the developer is requested to provide block-by-
block layouts of how the neighborhood will appear and how the streetscape will look.
Mr. Way inquired if the intent of the Guidelines is to require more side or rear-facing garages.
Ms. Holt responded that is the intent. With the larger, manor lots, the emphasis is on side-entry
garages with porte cochere/courtyard driveways. On narrow lots, that is not possible.
Mr. Way agreed that a rear-entry garage would be necessary on a narrow lot.
Public Comment
No public comments were received.

Commission Discussion
Commission members discussed whether the proposed Guidelines and Code amendments
provided sufficient guidance in certain areas to implement the vision of City Council into future
PUDs.
Stormwater Features
Mr. Way stated that he had no objection to the proposed language; interactive is the key word.
Ms. Call recommended that images of what would be acceptable and not acceptable be added.
Mr. Fishman reiterated his concern about watering be counted as open space if a dock, for
instance, were added.
Ms. Call responded that #6 says “it shall not count unless…;” however, #7 says “it may count….”
She would prefer both say, “it shall not count unless.”
[Discussion continued re superior and interactive designs.]
The majority of Commission members were supportive of the proposed language.
Mr. Boggs pointed out that right now, there is no guiding language regarding stormwater basins.
However, because these are legislative decisions, as long as it is not arbitrary and capricious, the
City’s decision should stand. Adopting the Guidelines would provide an extra layer, placing the
burden on the developer to show the Commission that the proposed stormwater feature has a
superior, interactive design. He believes this provides more guidance to applicants, who are willing
to accept that guidance. It provides a framework for the Commission to have its discussion, and
ultimately, to help in the interactive process with the developer to achieve the PUD text and plat,
which will be the governing documents.
Lot Coverage
Ms. Call stated that the proposed language indicates that the lot coverage and setback
requirements for residential development should follow the Neighborhood Design principles;
language was also added about street tree varieties.
Mr. Fishman stated that the trend is to permit more lot coverage to achieve more density, but it
should be necessary to trade something for that additional lot coverage. We have learned from
previous experience where individual lots in a subdivision did not have sufficient room for AC units
or patios; therefore, the language should be tight enough to ensure there is adequate room on
individual lots for those necessities.
Mr. Way stated that there is the opportunity in a PUD to give up individual lot space in order to
build more open space, perhaps by clustering units on tighter lots to preserve open space. There
is the opportunity for trade-off.
Ms. Call stated that the requirement of a build envelope for every lot should ensure future
Commissions have that information before them for their consideration.
Mr. Supelak stated that perhaps, when some developments initially came before the Commission,
that item was not addressed.
Mr. Fishman stated that in the situation he recalls, it was discussed by that Commission, but,
unfortunately, they approved the development without sufficient room on individual lots for the
HVAC units.
Ms. Holt stated that as shown on the Powerpoint, Location K places the HVAC equipment behind
the principal structure; it is prohibited in the sideyard, which will prevent that issue occurring. The
Planning and Zoning Commission DRAFT

applicant will be required to show how their house type will fit on their lot type, meeting the
standards in every block. This is intended to avoid an Oak Park or Hamlet-type situation.
Ms. Call stated that the home product in the Oak Park subdivision is nice; however, the developer
did not anticipate that homebuyers would choose the largest home on the smaller lots. They
anticipated more of a variety, but in that subdivision, many of the lots did not have adequate
space for patios.
Section 153.134A(d) - Street Trees
Ms. Call requested clarification of the landscape plan reviews conducted for PUD applications.
The goal is to permit areas to emphasize neighborhood individuality, highlight intersections and
pedestrian facilities, and complement the size and massing of the surrounding architecture. Those
are clues as to what type of landscaping the City is expecting to see, yet allowing creativity.
Ms. Call requested clarification of the staff review process re. acceptable tree species, placement,
variety, before or after presentation to the Commission.
Ms. Holt responded that the landscape plan would follow the standard review process. The
divisions of Forestry and Zoning review the plans; staff comments are compiled and shared with
the applicant.
Ms. Call stated that with that explanation, she has no objection to the proposed language.
Mr. Supelak inquired if there is merit to having a standard for street tree heights. Trees of less
height do not achieve the desired street character/ambience.
Mr. Way responded that as long as there is a plan or concept that defines what kind of trees and
effect is desired, there is no need for more detail. The PUD design should have a concept for the
street landscape.
Mr. Supelak stated that his concern is that the City might end up with trees that never achieve a
perception of maturity. The focus should be the appearance of the mature tree.
Ms. Call inquired if the mature height of trees is addressed in the landscape review process.
Ms. Holt responded affirmatively.
Mr. Supelak stated that the proposed language addresses alternate block arrangements. The
language in the Guidelines state, “where blocks of dwelling units are arranged to front onto public
open space with garages located at the back of the lot, the distance from the front door to the
public street must be carefully considered to maintain a sense of connectedness to the public
realm and the surrounding community of neighbors.” Is the Commission satisfied with that
language?
Mr. Schneier stated that he would object if it were the Code la nguage, but the Guidelines language
provides guidance in developing the PUD development text.
Commissioners had no objection to the language.

Mr. Schneier moved, Mr. Way seconded to revise the word “per” to “pursuant to” in #7 of Section
153.052(B)(3)(d) - Open space, and recommend City Council approval of the following Code
Amendments:
§152.002 PLANNED UNIT DEVELOPMENT. An area of land, zoned under § 153.056, in
which a variety of housing types and/or related commercial and industrial facilities are clustered
in an imaginative preplanned fashion to permit the development of the land in an orderly,
coordinated and comprehensive manner by preserving the natural quality and beauty of the land
and providing a more livable housing environment. To foster creative planning, more flexible
standards for streets, drainage, setbacks, lot sizes, etc. are provided within these subdivision
regulations that are designed to meet the kinds of design conditions that exist within PUDs and
which are examined and reviewed with §§ 153.050 through 153.058. The Planned Unit
Development is for the purpose of conserving land through more efficient allocation of private
lots, multi-family dwelling units, common grounds and nonresidential uses, promoting greater
efficiency in providing public and utility services, and securing the benefits of new techniques of
community development and renewal. Within a residential Planned Unit Development district or
zone, the Zoning Ordinance regulations need not be uniform, but may vary in order to promote
the public health, safety and morals, and the other purposes, as specifically identified in the
Neighborhood Design Guidelines and other related documents. Adopted regulations may require
developers to obtain conditional or final certification of compliance with the zoning ordinance at
specified stages of development. As used herein, Planned Unit Development means a development
which is planned to integrate residential use with collateral uses, and in which lot size, set-back
lines, yard areas and dwelling types may be varied and modified to achieve particular design
objectives and make provision for open spaces, common areas, utilities, public improvements and
collateral nonresidential uses.
152.086 Open Space Requirements. (A) Land dedication. The basic land dedication
requirement shall be that 2% of the total gross site area, plus .03 acres per dwelling unit proposed,
shall be set aside as open space except that in no case shall the open space requirement exceed
25% of total gross site area. Such area shall constitute ground suitable for public parks and
playground facilities as reviewed and approved by the Planning and Zoning Commission. For
residential PUDs, location and quality of open space is addressed in the Neighborhood Design
Guidelines.
153.050(A) Purpose. The Planned Unit District (PUD) regulations are based on the premise
that the ultimate quality of a built environment or development proposal is determined not only
by the type, character and allocation of land uses but also by the way in which such land uses are
executed. In many cases, the subdivision regulations and standard zoning district regulations and
procedures do not adequately regulate the design of buildings or enable the range of uses in a
single zoning district that are appropriate in the City. The City has adopted Neighborhood Design
Guidelines to ensure that these higher standards are met.
§153.052(B)(3)(d): Open space. Adequate open spaces shall be integrated throughout the
development to meet the objectives of the Community Plan and shall comply with the open space
Planning and Zoning Commission DRAFT
Meeting Minutes – January 19, 2023
Page 8 of 11
requirements set forth in Chapter 152, Subdivision Regulations. PUDs that include residential uses
shall include open space that is located and designed as follows:
1. Open space shall be sufficiently aggregated to create large useable areas of planned open
space.
2. Open space shall conserve significant natural features within the PUD to the extent
practicable.
3. Open space shall provide a scenic natural environment along existing public streets
characterized by large building setbacks that enable the preservation of natural features.
4. All open space shall be easily accessible to residents of the PUD.
5. Where possible, open space areas shall be connected with open space areas on abutting
parcels, and wherever possible, by open space corridors
6. Stormwater features shall not count as open space, unless they achieve a superior,
interactive design as outlined in the Neighborhood Design Guidelines.
7. Unbuildable easements and required setbacks may count toward open space when they
are integrated into the overall Open Space Framework pursuant to the Neighborhood
Design Guidelines.
§153.054(A): Contents of concept plan application. It is the intent of these regulations that
the concept plan shall generally indicate overall design of the proposed project, including
conformance with the Neighborhood Design Guidelines for residential projects. Information
submitted should be comprehensive enough to enable the staff to understand the existing site
and concept for the proposed development. The applicant shall submit a number of copies as
determined by the Director of Planning. The information submitted should include the following:
§153.054(B): Contents of preliminary development plan application. The application shall
include the maps, plans, and supplementary documentation itemized below and as indicated in
the Neighborhood Design Guidelines for residential projects. The applicant shall submit a number
of copies as determined by the Director of Planning. The information submitted should include the
following:
§153.054(C): Contents of final development plan application. The application shall include the
maps, plans, designs and supplementary documents itemized below, and as indicated in the
Neighborhood Design Guidelines for residential projects. Copies of the maps, plans, designs and
supplementary documents shall be submitted. Final development plans are intended to be detailed
refinements for development and, as such, shall be accurate, detailed representations of the total
aspects of the approved preliminary development plan. The applicant shall submit a number of
copies as determined by the Director of Planning. The information submitted shall include the
following:
§153.071(4)(e): Unless otherwise required in an approved Planned Unit Development,
structures, parking, driveways, vehicular use areas, service areas, pedestrian areas, and other
hard-surfaces or paved areas may cover more than 45% of the total lot area within a residential
PUD District with design following the Neighborhood Design Guidelines.
§153.134(A)(1)(a-g): Requirements. It shall be required that all subdividers or developers
plant trees along public streets of their developments in such a manner, type, quantity and location
as approved by the Planning and Zoning Commission and as defined by the following conditions,
Planning and Zoning Commission DRAFT
Meeting Minutes – January 19, 2023
Page 9 of 11
and that any undeveloped street or existing street with undeveloped frontage shall conform to
these requirements at the time of the development. Final tree locations may be adjusted by the
City as unusual conditions may warrant.
(a) The tree to be planted shall be an approved street tree as listed in Appendix E
(Approved Street Trees for Dublin, Ohio).
(b) The minimum spacing between this and other trees shall be 40 feet for large trees, 30
feet for medium trees and 20 feet for small trees. See definition below.
(c) The maximum spacing between trees shall be 45 feet for large trees, 35 feet for
medium trees, and 25 feet for small trees. Spacing may be adjusted for columnar trees, as
approved by City Forestry Division.
(d) Size and spacing of street trees shall be designed to emphasize neighborhood
individuality, highlight the importance of intersections and pedestrian facilities, and compliment
the size and massing of surrounding architecture as noted in the Neighborhood Design Guidelines.
(e) The minimum distance between the tree and the edge of the street shall be two and
one-half feet for a large tree, two feet for a medium tree and one and one-half feet for a small
tree. In areas where a sidewalk exists or is proposed, the minimum distance between the tree
trunk and both the edge of the street and the sidewalks shall b e two feet for a large tree, two feet
for a medium tree and one and one-half feet for a small tree.
(f) The tree location shall be at least 20 feet from street intersections and ten feet from
fire hydrants or utility poles.
(g) A small tree shall be used when planting under or within ten lateral feet of overhead
utility wires. A small or medium tree shall be used when planting within ten to 20 lateral feet of
overhead utility wires.
§153.190(A): Residential appearance. The following findings warrant the need for exterior
appearance requirements for residential development for standard zone districts. PUDs are
required to use the Neighborhood Design Guidelines.
§153.190(B)(2): Residential appearance in Planned Unit Development Districts shall be

board members identified the need for additional architectural resources and support. Planning
staff already provides a similar resource to the Architectural Review Board, but to meet the
increasing needs of Planning staff and boards and commissions, staff has contracted with Ford
and Associate Architects to provide on-call professional architectural services. Mr. Ford has nearly
30 years of experience, including past consultant work for the City of Dublin.
Mark Ford, Ford and Associates Architects, Grandview, Ohio stated that he established his
Columbus-based firm in 1993, and has presented before the Planning and Zoning Commission
numerous times, primarily on commercial projects. He looks forward to working with the City on
future projects.
COMMUNICATIONS
Future Proposed Code Amendment re. open and uncovered structures.
Ms. Holt stated that in February 2022, the BZA heard an administrative appeal regarding the
encroachment of a pergola into a setback. Although the Board di d not approve the encroachment,
they directed staff to work on a Code definition for open and uncovered structures. If the
Commission has suggestions/comments to share, she would be happy to provide them to staff for
consideration, as they work on this Code amendment.
Ms. Call suggested that if appropriate, solar accessory structures be included in this Code
amendment, as well.
Mr. Schneier stated that it would be helpful to have photos provided as examples of what
might/might not be acceptable.
Mr. Way stated that he has concerns about permitting some encroachments, but not others.
Ms. Call requested that with the presentation of the Code amendment, staff provide the history
regarding what encroachments the City has permitted.
Ms. Harter stated that often, amenities, such as fans or hot tubs, are placed in pergolas, and they
can cause distraction or noise issues for the neighbors. These structures could cause issues, as
well, for HOAs, which might have rules that prohibit them.
Mr. Boggs responded that the intent of the proposed Code amendment is to clarify the ambiguity
over open and uncovered structures versus a pergola, etc. The City will decide what its standards
will be. Ultimately, it is up to the HOA to enforce their own restrictions, whatever they may be.
Community Plan Update Kick-off event - March 28-30, 2023.
Mr. Will stated that much has changed in the City since its last Community Plan update in 2007.
Staff has contracted with Houseal Lavigne, a Chicago-based urban planning and design firm to
facilitate the anticipated 18-month process. The City will host the consultant team for a kick-off
event March 28-20, 2023. He inquired if Commission members had any conflicts with the dates.
Commission members indicated they had no date conflicts.

Re: Neighborhood Design Guidelines Update, Case 22-177ADMO
Related Zoning Code Amendments, Case 23-002ADMC
Summary
City Council and the Planning and Zoning Commission (PZC) have discussed the
opportunity for more creative and sustainable residential neighborhoods in Dublin relative
to community character, open spaces, amenities, setbacks, and lot coverage. Recent
residential developments reviewed by PZC and Council have raised concerns about the
overall design character and development standards, and they have asked staff to
address these concerns in a more comprehensive way. Planning staff conducted a series
of Work Sessions with City Council and PZC to gather information on key areas of concern.
Based on that input, staff and our consultant have created design guidelines that support
the Code’s PUD intent language and encourage the desired outcomes.
The draft Guidelines were shared with the Community Development Committee (CDC) on
September 28, 2022, and the Committee Members provided feedback to staff. A status
update was provided to CDC on November 28, 2022, and the Committee confirmed the
project direction and how the comments were addressed. The project was then brought
to PZC on December 8, 2022 for a final discussion prior to a recommendation. The
Commission was given the opportunity to provide further thoughts and edits, which have
been incorporated in the proposed draft. Accompanying Code amendments are outlined
below for the Commission’s review and recommendation in conjunction with the draft
Guidelines. Staff requests a formal recommendation be made to City Council on the draft
Guidelines and Code Amendments.
Background
The topic of residential development standards was initially referred to PZC by Council
on June 22, 2020 following concerns related to the Hamlet on Jerome and Oak Park
developments. PZC was introduced to the topic on August 20, 2020 and subsequently
discussed it on October 1, 2020. The Commission’s discussion centered on defining a
holistic intent for future residential developments to be timeless, provide a sense of
community, and maintain the desired character of Dublin. Other goals included:
1. Avoid being so prescriptive as to limit development and design opportunities;

2. Understand the community’s needs and wants for housing, as well as
what other communities are experiencing with residential development; and
3. Retain existing Code standards for lower density development with
exemptions for higher density where quality of life attributes are provided.
Since these initial discussions, PZC and Council have had further discussions resulting from the
Dublin Gateway, Overlook at Tartan Ridge, Ayrshire, and Hyland Glen projects. Both groups
have raised additional topics of lot coverage, building coverage, setbacks, building materials,
open space amenities and connectivity. Numerous v ariance applications at the Board of
Zoning Appeals were also discussed as part of the joint meeting between the Boards, Commission
and Council on December 14, 2020. As part of their work plan for 2021, PZC identified this topic as
a target item for the latter part of the year. Staff outlined a comprehensive project work plan at
the November 4, 2021 PZC meeting and provided an overview of the existing regulations that
govern general residential development. The Commission supported the proposed plan, provided
additional feedback, and recommended that the proposed solution should focus on residential
PUD projects only, given the limited amount of standard zoning acreage remaining for residential
development.
Per the work plan, a series of workshops were held in January 2022 for PZC members and
incoming/outgoing Council representatives. Staff requested PZC review a series of discussion
topics for feedback: different housing types and details for further study; information about
housing types, trends and consumer needs to inform the conversation; and specific dimensional
standards. Members were also asked to provide positive and negative examples of residential
developments (local/national/international) for discussion. A summary of the feedback was
provided, along with recommended solutions, and each were confirmed by the group.
A City Council Work Session was held on April 18, 2022 to share the results and preliminary
recommendations from the PZC discussions. Council Members provided input on the preliminary
design standards which are organized from the broad, foundational framework of the overall
neighborhood, to the street network and streetscape design, then to specific details of individual
lots. The design guidelines were further refined and expanded based on their feedback.
More recently, Council raised questions regarding stormwater basins and whether they should be
counted toward required open space in residential projects. Concerns were raised that the size of
the basins are a significant portion of open space within these neighborhoods, leaving limited
usable open space for residents. The topic was referred to CDC and discussed on September 28,
and November 28, 2022. At that time, CDC agreed that the project was ready for PZC
consideration and discussion, which occurred on December 8. Subsequent to a very positive
discussion, staff requested that any more detailed comments be provided by December 16, and
these comments have been incorporated into the final draft Guidelines and Code attached. Once
the Commission recommends approval, staff will schedule the Guidelines and Code for City
Council adoption.
Neighborhood Design Guidelines
The draft Neighborhood Design Guidelines provides a series of design solutions for evaluation of
future residential PUD projects to ensure the City’s desired design goals are met. The Guidelines
are organized into a hierarchy of three levels from the broad macro public realm of open spaces
Memo re. Residential Development Standards Update
January 19, 2023
Page 3 of 6
and preservation areas, to the micro level public realm of streetscapes as outdoor rooms, to the
private realm of individual lots and the functions of various areas within the lots and lot types.
Public Realm, Macro Level
The macro level of the public realm is the organization of neighborhoods around a designed
framework of public open space, including both the preservation of existing natural features and
the thoughtful creation of new open spaces as neighborhood amenities and focal points. The
Guidelines reference the applicability of conservation design within PUDs and offer an alternative
for projects of any size and location in the new Open Space Framework requirement.
Public Realm Micro Level
The micro public realm focuses on the design character of neighborhood streetscapes as high-
quality public and semi-private spaces. The Guidelines reference the applicability of the
Residential Appearance Code as the minimum, emphasize that PUD expectations are higher based
on Code intent language, and provide aspirational ideas and images appropriate for PUDs.
Private Realm
The private realm addresses the need to ensure adequate private space within each lot,
independent of lot size. Included are requirements for setbacks, AC locations, yards, and buildable
areas. Multiple-lot exhibits would be required as part of a Concept Plan application to better
understand development patterns within a typical block of a proposal.

Zoning Code Amendments
In addition to the proposed Neighborhood Design Guidelines, staff has identified a series of
Code amendments that need to be considered to achieve the desired character. These were
presented to the Commission for discussion and confirmation on December 8. Staff identified
additional Code amendments that were needed to ensure the procedural connection between
residential development activities and the new Guidelines are made, and these are outlined
generally below. Draft Code language is attached for review.
1. §152.002: In order to link the Subdivision Regulations platting activity in PUDs, with the
new Neighborhood Design Guidelines, a reference to the Guidelines is made.
2. §152.086: The Open Space Requirements refer to the Guidelines for residential PUDs.
3. §153.050: The PUD section of the Code should also have specific links to the Guidelines
as part of the purpose and application introductory section.
4. §153.052: A request was made from Council that stormwater ponds not count as open
space. Staff has drafted a Code amendment that will describe that they only be
permitted to count with superior design.
Current Code permits the use of easements and required setbacks as open space, and
these areas, unless carefully designed, can become straight, unimaginative alleys. Staff
has drafted a Code amendment about how these areas shall be integrated into a
broader and more meaningful open space network.
Memo re. Residential Development Standards Update
January 19, 2023
Page 6 of 6
5. §153.054(A), (B), and (C): Links the submittal requirements for Concept Plan, PDP, and
FDP to the Neighborhood Design Guidelines.
6. §153.071(4)(e): During the interviews, all PZC and Council members indicated that they
would not be opposed to higher densities where design is superior. Current maximum
lot coverage is capped at 45 percent per the Code, which limits higher densities and
different housing products. Staff has drafted a Code amendment, with goal language, to
allow this possibility within PUDs.
7. §153.134(A)(1)(a-f): Commission and Council members agreed that creative
landscaping, especially street trees, is imperative to making a sense-of-place within a
neighborhood. This section of the Code currently permits a variety of large, medium,
and small street trees with corresponding spacing requirements. The corresponding
Guidelines III, D speak to these goals, so staff proposes code language to emphasize
that design intent.
8. §153.190(A), (B) and (C): Clarifications that the Appearance standards apply only to
standard zoning and are not intended for residential PUDs; these use the Neighborhood
Design Guidelines.
Recommendation
Planning recommends the Planning and Zoning Commission make a recommendation of approval
of the Neighborhood Design Guidelines and associated Zoning Code amendments to City Council.
EXISTING CODE LANGUAGE RELATED TO SFR PUDs
and NEIGHBORHOOD DESIGN GUIDELINES
§152.002 PLANNED UNIT DEVELOPMENT. An area of land, zoned under § 153.056, in
which a variety of housing types and/or related commercial and industrial facilities are clustered
in an imaginative preplanned fashion to permit the development of the land in an orderly,
coordinated and comprehensive manner by preserving the natural quality and beauty of the land
and providing a more livable housing environment. To foster creative planning, more flexible
standards for streets, drainage, setbacks, lot sizes, etc. are provided within these subdivision
regulations that are designed to meet the kinds of design conditions that exist within PUDs and
which are examined and reviewed with §§ 153.050 through 153.058. The Planned Unit
Development is for the purpose of conserving land through more efficient allocation of private
lots, multi-family dwelling units, common grounds and nonresidential uses, promoting greater
efficiency in providing public and utility services, and securing the benefits of new techniques of
community development and renewal. Within a residential Planned Unit Development district or
zone, the Zoning Ordinance regulations need not be uniform, but may vary in order to promote
the public health, safety and morals, and the other purposes, as specifically identified in the
Neighborhood Design Guidelines and other related documents. Adopted regulations may
require developers to obtain conditional or final certification of compliance with the zoning
ordinance at specified stages of development. As used herein, PLANNED UNIT
DEVELOPMENT means a development which is planned to integrate residential use with
collateral uses, and in which lot size, set-back lines, yard areas and dwelling types may be
varied and modified to achieve particular design objectives and make provision for open spaces,
common areas, utilities, public improvements and collateral nonresidential uses.
152.086 Open Space Requirements. (A) Land dedication. The basic land dedication
requirement shall be that 2% of the total gross site area, plus .03 acres per dwelling unit
proposed, shall be set aside as open space except that in no case shall the open space
requirement exceed 25% of total gross site area. Such area shall constitute ground suitable for
public parks and playground facilities as reviewed and approved by the Planning and Zoning
Commission.
153.050(A) Purpose. The Planned Unit? District (PUD) regulations are based on the premise
that the ultimate quality of a built environment or development proposal is determined not only
by the type, character and allocation of land uses but also by the way in which such land uses
are executed. In many cases, the subdivision regulations and standard zoning district
regulations and procedures do not adequately regulate the design of buildings or enable the
range of uses in a single zoning district that are appropriate in the city.
§153.052(B)(3)(d): Open space. Adequate open spaces shall be integrated throughout the
development to meet the objectives of the Community Plan and shall comply with the open
space requirements set forth in Chapter 152, Subdivision Regulations. PUDs that include
residential uses shall include open space that is located and designed as follows:
1. Open space shall be sufficiently aggregated to create large useable areas of
planned open space.
2. Open space shall conserve significant natural features within the PUD to the extent
practicable.
3. Open space shall provide a scenic natural environment along existing public streets
characterized by large building setbacks that enable the preservation of natural features.
4. All open space shall be easily accessible to residents of the PUD.
5. Where possible, open space areas shall be connected with open space areas on
abutting parcels, and wherever possible, by open space corridors
§153.054(A): Contents of concept plan application. It is the intent of these regulations that
the concept plan shall generally indicate overall design of the proposed project. Information
submitted should be comprehensive enough to enable the staff to understand the existing site
and concept for the proposed development. The applicant shall submit a number of copies as
determined by the Director of Planning. The information submitted should include the following:
§153.054(B): Contents of preliminary development plan application. The application shall
include the maps, plans, and supplementary documentation itemized below. The applicant shall
submit a number of copies as determined by the Director of Planning. The information submitted
should include the following:
§153.054(C): Contents of final development plan application. The application shall include
the maps, plans, designs and supplementary documents itemized below. Copies of the maps,
plans, designs and supplementary documents shall be submitted. Final development plans are
intended to be detailed refinements for development and, as such, shall be accurate, detailed
representations of the total aspects of the approved preliminary development plan. The
applicant shall submit a number of copies as determined by the Director of Planning. The
information submitted shall include the following:
§153.071(4)(e): Unless otherwise required in an approved Planned Development, structures,
parking, driveways, vehicular use areas, service areas, pedestrian areas, and other hard-
surfaces or paved areas shall not cover more than 45% of the total lot area within a residential
PUD District.
§153.134(A)(1)(a-f): Requirements. It shall be required that all subdividers or developers
plant trees along public streets of their developments in such a manner, type, quantity and
location as approved by the Planning and Zoning Commission and as defined by the following
conditions, and that any undeveloped street or existing street with undeveloped frontage shall
conform to these requirements at the time of the development. Final tree locations may be
adjusted by the city as unusual conditions may warrant.
(a)The tree to be planted shall be an approved street tree as listed in Appendix E
(Approved Street Trees for Dublin, Ohio).
(b)The minimum spacing between this and other trees shall be 40 feet for large trees, 30
feet for medium trees and 20 feet for small trees. See definition below.
(c)The maximum spacing between trees shall be 45 feet for large trees, 35 feet for
medium trees, and 25 feet for small trees.
(d)The minimum distance between the tree and the edge of the street shall be two and
one-half feet for a large tree, two feet for a medium tree and one and one-half feet for a small
tree. In areas where a sidewalk exists or is proposed, the minimum distance between the tree
trunk and both the edge of the street and the sidewalks shall be two feet for a large tree, two
feet for a medium tree and one and one-half feet for a small tree.
(e)The tree location shall be at least 20 feet from street intersections and ten feet from
fire hydrants or utility poles.
(f)A small tree shall be used when planting under or within ten lateral feet of overhead
utility wires. A small or medium tree shall be used when planting within ten to 20 lateral feet of
overhead utility wires.
§153.190(A): Residential appearance. The following findings warrant the need for exterior
appearance requirements for residential development.
§153.190(B)(2) Planned Development Districts. Residential appearance objectives for
Planned Development Districts shall be adopted by City Council. These objectives explain more
general intents regarding appearance in order to allow for creativity in meeting them through
the Planned Development District process. Planned Development District proposals must
demonstrate how the proposal addresses the residential appearance objectives and replace
these minimum requirements.
§153.190(C)(3): Houses in districts described below are exempt or must comply with these
requirements as follows:
(a) Houses located within a planned district approved after the effective date of this
section shall comply with the requirements of this section, or with specific substitute residential
appearance requirements contained in the adopted planned district ordinance. These residential
appearance requirements shall apply unless specifically stated substitute requirements are
approved in the planned district ordinance. In the case of absent, or non-specific requirements
in the planned district ordinance, the more restrictive requirement will apply.
