A, based on the following findings:
SECTION 1— FINDINGS
General Plan Findings:
1. The project must be consistent with the goals and policies stated within the City's General
Plan.
The update to the Historic Preservation Design Standards for Old Towne Orange is consistent
with the General Plan goals and policies of the Cultural Resources & Historic Preservation
Element in that the update to the Design Standards directly incorporates the Secretary's
Standards and related guidance from the National Park Service on the treatment of historic
properties. As a result, projects that are in conformance with the Design Standards will also
Resolution No. 11053 2
be in conformance with the Secretary's Standards. The update brings the Design Standards
more closely into alignment with the Secretary's Standards and ensures the long -term
preservation of historic resources by emphasizing the preservation and retention of historic
materials and features.
The Design Standards update is also consistent with the goals and policies of the Urban
Design Element, because the update clarifies the standards for new construction related to
historic buildings, including additions and infill construction, to ensure that the mass, scale,
design, and materials of these projects are compatible with the character of the Historic
Districts and in conformance with the Secretary's Standards. The update improves the
existing Design Standards by clearly describing the expectations for high - quality
rehabilitation of historic buildings and compatible new construction to ensure transparency
for property owners and design professionals working in the Historic District. It continues
the long - standing emphasis of the Design Standards on preservation of the character of Old
Towne as a historic neighborhood, including the incorporation of appropriately scaled and
detailed new construction.
SECTION 2 — ENVIRONMENTAL REVIEW
The update to the Design Standards is categorically exempt from the provisions of the California
Environmental Quality Act (CEQA) per State CEQA Guidelines 15308 (Class 8 - Actions by
Regulatory Agencies for Protection of the Environment) and 15331 (Class 31 - Historical Resource
Restoration/Rehabilitation). The update clarifies and improves the existing Historic Preservation
Design Standards for Old Towne Orange, which were adopted by City Council in 1995 for the
protection for the local and National Register- designated Old Towne historic districts. This update
of existing procedures, policies, and standards is consistent with the City Council's prior action
adopting the Design Standards in order to preserve designated historic resources. It assures the
maintenance and protection of the environment through the preservation of historic resources and
appropriate standards for new construction in the historic districts, as required by the Class 8
exemption.
In addition, the update to the Design Standards is written such that projects found to be in
conformance with the Design Standards will also be in conformance with the Secretary of the
Interior's Standards for the Treatment of Historic Properties (Secretary's Standards). The update
is consistent with and uses extensive guidance from the National Park Service on interpreting and
implementing the Secretary's Standards, including the Guidelines for Preserving, Rehabilitating,
Restoring, and Reconstructing Historic Buildings. The updated Design Standards are in
conformance with the Secretary's Standards and projects designed in conformance therewith will
be categorically exempt from environmental review under the Class 31 exemption for Historical
Resource Restoration/Rehabilitation.
There is no environmental public review required for a Categorical Exemption.

PURPOSE OF THE DESIGN STANDARDS
The residents of Orange have shown consistently that historic preservation is an important
value of our community. Orange is a special place to live in part because of the historic
buildings that help to create neighborhood character. Beginning in the 1970s, Orange's
historic resources have been preserved through the joint efforts of community groups.
Early preservation achievements included the Chapman College (now Chapman
University) nomination of the Orange Union High School campus to the National
Register of Historic Places (National Register) in 1975 and the Orange Community
Historical Society's nomination of the Plaza to the National Register in 1978.
In 1982, in response to community interest, the City initiated the first historic
resources survey of pre -1940 buildings in Orange, with a focus on the Old
Towne area. That same year, the Orange Community Historical Society and the
City partnered on the National Register designation of the Plaza Historic District,
consisting of the four commercial blocks around Plaza Park. By 1985, a second
community organization was established to advocate for historic reservatiop nm
Old Towne: the Old Towne Preservation Association (OTPA). An update of the historic
resources survey was completed by the City in 1992, and the survey update was used to
establish the local Old Towne Historic District, a nearly mile square area of historic residential,
commercial, institutional and industrial buildings, centered on the historic downtown core.
Working with community groups, the City developed and adopted the Historic Preservation
Design Standards for Old Towne, or Old Towne Design Standards, in 1995 to provide
property owners guidance on how to maintain and repair historic buildings and plan for
new construction. In 1997, a more concentrated version of the local Old Towne Historic District
was listed in the National Register through a nomination prepared by OTPA. The Orange Barrio
Historical Society was also founded by local residents to celebrate and preserve the character of
the Cypress Street Barrio, a neighborhood historically settled by Mexican and Mexican American
families that developed around Cypress Street starting in the 1890s. The Old Towne Preservation
Association, Orange Community Historical Society, and Orange Barrio Historical Society remain
active participants in historic preservation in Orange.
As demonstrated by the dedicated efforts of residents and community groups, Orange's
historic buildings and neighborhoods convey a distinct sense of place. The purpose of the
Historic Preservation Design Standards (HPDS) is to protect this unique character. The HPDS help
property owners, design professionals and residents understand the features that make buildings
and neighborhoods special and provide guidance on how best to preserve those features. The
HPDS also guide the design of new construction so that it relates respectfully to historic buildings.
The HPDS recognize that historic buildings and neighborhoods change over time. New buildings
do not necessarily need to look old, but should closely relate to the mass, scale, form and setbacks
of historic buildings. The review process established through the HPDS ensures that proposed new
construction is compatible with existing historic features through range of flexible design guidelines.
y
the community- driven interest in historic preservation,
ire are sound economic reasons why historic preservation makes sense.
Historic preservation increases property values. Studies have consistently
shown that properties in historic districts with robust design guidelines
have higher property values than surrounding neighborhoods, even when
compared with adjacent blocks that have similar lot and house sizes
Historic preservation creates jobs. Rehabilitation of historic buildings
requires skilled craftspeople who are familiar with local construction
methods and materials. While much attention is given to jobs created
by new construction, rehabilitation of historic buildings also creates
many jobs in local construction trades and supports the local economy
Historic preservation attracts visitors. Heritage tourism is an expanding
industry, and preserving historic buildings enhances the City's tourism
potential, which benefits small businesses and the local economy
Historic preservation is sustainable development. Preservation means maintaining and
re -using existing buildings, which is essentially recycling on a neighborhood scale. If an
existing building is demolished, all of the energy that went into the extraction of raw
materials, transportation, manufacturing, distribution and construction is lost. Demolition
is ultimately a lost investment in the craftsmanship and materials of historic buildings,
while rehabilitation re -uses and reinvests in these assets
RELATED GUIDANCE
Secretary's Standards
The National Park Service has developed historic preservation standards, called the
Secretary of the Interior's Standards for the Treatment of Historic Properties (Secretary's
Standards) that apply to a wide variety of historic properties across the country. The
Secretary's Standards are a series of concepts about maintaining, repairing, and replacing
historic materials, as well as designing new additions or making alterations. The Secretary's
Standards address four treatments for historic properties: preservation, rehabilitation,
restoration, and reconstruction.
Preservation is the act or process of applying measures necessary to sustain the existing
form, integrity, and materials of a historic property. Work generally focuses on ongoing
maintenance and repairs of historic materials and features rather than extensive replacement
or new construction.
WHY HISTORIC PRESERVATION?
Rehabilitation is the act or process of making possible a compatible use for
a property through repair, alterations, and additions while preserving those
portions or features which convey its historical, cultural, or architectural
values.
Restoration is the act or process of accurately depicting the form, features,
and character of a property as it appeared at particular period of time
by means of the removal of features from other periods in its history and
reconstruction of missing features from the restoration period.
Reconstruction is the act or process of depicting, by means of new
construction, the form, features, and detailing of a non - surviving site,
landscape, building, structure, or object for the purpose of replicating its
appearance at a specific period of time and in its historic location.
The Guidelines for Preserving, Rehabilitating, Restoring and Reconstructing
Historic Buildings offer general design and technical recommendations to
assist in applying the Standards to a specific property. Together with the
Standards, they provide a framework and guidance for decision - making about
changes to a historic property.
The Secretary's Standards and Guidelines can be applied to historic properties
of all types, materials, construction, sizes, and uses. They include both the
exterior and the interior and extend to a property's landscape features, site,
environment, as well as related new construction. Federal agencies use
the Standards and Guidelines in carrying out their historic preservation
responsibilities. State and local officials use them in reviewing both
Federal and nonfederal rehabilitation proposals.
In Orange, the Standards and Guidelines guide design review of
projects in Old Towne and are used to supplement and support
the Historic Preservation Design Standards. Projects in the Old
Towne historic districts should be in conformance with both the
Secretary's Standards and the Historic Preservation Design Standards.
The HPDS are written to be consistent with the Secretary's Standards, so
projects that are found to be in conformance with the HPDS generally are
considered to be in conformance with the Secretary's Standards.
Most projects will apply the Rehabilitation Standards, which acknowledge
the need to alter or add to a historic building to meet continuing or new uses
while retaining the building's historic character. The Rehabilitation Standards
consist of ten principles:
1. A property will be used as it was historically or be given a new use that requires minimal
change to its distinctive materials, features, spaces, and spatial relationships.
2. The historic character of a property will be retained and preserved. The removal of
distinctive materials or alteration of features, spaces, and spatial relationships that
characterize a property will be avoided.
3. Each property will be recognized as a physical record of its time, place, and use. Changes
that create a false sense of historical development, such as adding conjectural features or
elements from other historic properties, will not be undertaken.
4. Changes to a property that have acquired historic significance in their own right will be
retained and preserved.
5. Distinctive materials, features, finishes, and construction techniques or examples of
craftsmanship that characterize a property will be preserved.
6. Deteriorated historic features will be repaired rather than replaced. Where the severity
of deterioration requires replacement of a distinctive feature, the new feature will match
the old in design, color, texture, and, where possible, materials. Replacement of missing
features will be substantiated by documentary and physical evidence.
7. Chemical or physical treatments, if appropriate, will be undertaken using the gentlest
means possible. Treatments that cause damage to historic materials will not be used.
8. Archeological resources will be protected and preserved in place. If such resources
lust be disturbed, mitigation measures will be undertaken.
9. New additions, exterior alterations, or related new construction will not
destroy historic materials, features, and spatial relationships that characterize
the property. The new work will be differentiated from the old and will be
compatible with the historic materials, features, size, scale and proportion, and
massing to protect the integrity of the property and its environment.
10. New additions and adjacent or related new construction will be undertaken in
such a manner that, if removed in the future, the essential form and integrity
of the historic property and its environment would be unimpaired.
i ne National Park Service has prepared guidance on how to interpret the
Secretary's Standards. These publications include Preservation Briefs, Preservation Tech
Notes, and Interpreting the Standards Bulletins available on the NPS website: www.nps.
gov /tps /standards.htm. They provide valuable guidance to supplement the HPDS, and we
encourage you to consult them while planning projects for your historic property. Appendix B
provides a complete list of these publications. They are also referenced throughout the HPDS.
Standards for Rehabilitation
Basic Principles for Applying the HPDS
The HPDS are based on the ten rehabilitation principles of the Secretary's Standards. Under
the HPDS, there is hierarchy of recommendations for historic buildings, starting with the least
invasive treatments and moving to those that require the most change. This sequence serves as
a foundation for planning projects involving historic buildings and should direct property owners
looking to maintain and repair the character - defining features of a historic building. Character -
defining features are those visual and physical features that comprise the appearance of a historic
resource. They may include the overall shape of a building, materials, craftsmanship, decorative
details, interior spaces and features, as well as various aspects of the site and environment.
Maintain character - defining features that are in good condition. Regular maintenance is critical
to long -term preservation of historic buildings.
2. Repair character - defining features that are deteriorated to the original condition. In most cases,
repair is better than replacement because it preserves the historic materials on the building.
Replace only the character - defining features that cannot be repaired. Replacement should be
in kind, matching the materials, details, and finish of the feature.
4. Reconstruct missing character - defining features. The reconstruction should be based on
documentary or physical evidence on the building.
5. Design new features or additions to be compatible with the historic building and
minimize the impact to character - defining features.
The HPDS draw from this sequence to establish appropriate treatments for
specific building types and features.
California Historical Building Code
The City of Orange has adopted use of the California Historical Building Code (California
Code of Regulations, Title 24, Part 8) for historic Drooerties. ThP niirnnca of tkn
California Historical Building Code (CHBC) is to provide solutions for the preservation
of qualified historical properties, to promote sustainability, to provide access for
persons with disabilities, to provide a cost - effective approach to preservation,
and to provide for the reasonable safety of occupants or users. The CHBC
allows the City to accept solutions that are reasonably equivalent to the regular
building code when dealing with qualified historical properties. A qualified
historical property is any building, site, object, place, location, district or
collection of structures, and their associated sites, deemed of importance to the
history, architecture, or culture of an area by an appropriate local, state or federal
governmental jurisdiction. Historic buildings are qualified historical properties.
The City's Chief Building Official determines the appropriate use of the CHBC. If you
anticipate that your project will require use of the CHBC, please contact the Historic Preservation
Planner early in the process.

DO THE HPDS APPLY TO MY PROJECT?
The Historic Preservation Design Standards apply to properties located in established historic
districts. Orange has three established historic districts: the National Register Plaza Historic
District, the National Register Old Towne Orange Historic District, and the local Old Towne
Orange Historic District. These three overlapping historic districts are collectively called the Old
00, Towne historic districts.
Each historic district contains contributing and non - contributing structures which are identified
in the National Register designation form and the City's Historic Resources Inventory Update
adopted by City Council in 2010. A contributing structure is a structure that was constructed
within the period of significance for the historic districts and retains design elements and
materials from that period. A contributing structure must retain integrity, or the ability to convey
its associations with events, people or designs from the past through its historic materials and
forms. Contributing buildings are historically significant. Accessory structures that appear to have
been constructed during the period of significance are considered to be contributing structures
unless the property owner presents substantial evidence that the structure was not constructed
during the period of significance or has lost integrity. A non - contributing structure either was
constructed outside of the period of significance or has been altered so much that it no longer
retains the design elements and materials that identify it as being from that period. Non-
contributing buildings are not historically significant within the context of the historic district.
Period of significance is the span of time during which the significant
events or activities occurred. A period of significance can range from a
single day to many tens or hundreds of years, depending on the reason
why the property has historical significance. The periods of significance
for the Old Towne historic districts are found on pages 12 -13.
In some cases, properties that are identified as non - contributing to the Old Towne historic districts
may be separately significant as individual historic resources. This might occur if the property is
an important architectural style or associated with an important person or historical event,
separate from the context of the historic districts. If you are proposing changes to a
building that is more than 40 years old, please consult with Planning Division staff
early to determine the review process that may be required under the California
Environmental Quality Act (CEQA).
The HPDS apply to all properties in the three Old Towne historic districts, but a
different range of standards are used for contributing versus non - contributing
properties. Please visit the City's website gis /cityoforange.org /flexviewers/
HistoricPreservationViewer or contact Planning Division staff to determine if your
property is a contributor to the historic districts.
The different sections of the HPDS will apply based on the historical use of the
property. The Standards for Historic Building Features apply to all contributing properties.
The Standards for Historic Residential Buildings apply to all historic single - family and
multi - family residences and any buildings that were constructed as residences and have
since been converted to other uses. Similarly, the Standards for Historic Commercial
Properties apply to historic commercial buildings and any buildings that were constructed
for commercial use and have since been converted to other uses. Design guidelines for
historic industrial properties are included in the Santa Fe Depot Specific Plan and will apply
to projects involving changes to historic industrial properties.
DESIGN REVIEW
Design review is the approval process that ensures that projects in the historic districts
conform with the HPDS and the Secretary's Standards. To streamline review of repairs
and rehabilitation, many types of minor design review projects are delegated to staff of the
Planning Division in the Community Development Department. These projects are reviewed
by staff as Minor Design Review (MDR) applications. For work that qualifies for an MDR, you
can contact staff to review application materials during a visit to the Planning Division at the
Orange Civic Center.
Major projects are reviewed by the Design Review Committee. The Design Review
Committee (DRC) is a body of five professionals who have training, knowledge and
experience with architectural and site planning projects and are appointed by the City
Council. Members of the DRC may include landscape architects, architects, urban planners,
engineers, and general contractors. At least two of the members must have professional
experience with urban planning, architectural history or historic preservation. The DRC may
also serve as an advisory body to the Planning Commission or City Council for projects
involving substantial new construction.
A summary of common projects and their required review is provided in a table on
page 10.
Minor Design Review (MDR): An MDR is required for minor work on both contributing and
non - contributing properties in the historic districts. The MDR is a streamlined review process
for projects involving repairs or minor alterations that do not result in a substantial change
to the features or materials of the building. The applicant must file an MDR application with
the Planning Division. The following projects may be reviewed through an MDR application:
Repair or replacement of exterior doors, when compatible materials will be used
Repair or replacement of windows, when compatible materials will be used

The majority of projects will be reviewed and approved administratively. However,
ending on the complexity of the changes to the historic building, staff may refer
your project to the DRC for final determination.
If staff determines that your project does not meet the HPDS, it will not be
approved until changes are made to bring the project into conformance
with the Standards. You may choose to appeal staff's determination to the
DRC. All appeals shall follow the process described in Orange Municipal
Code Section 17 08 050, but shall be heard by the Design Review
Committee.
Design Review Committee (DRC): DRC is required for all major work on 2
both contributing and non - contributing properties in the historic districts.
The applicant must file a Design Review application with the Planning
Division, following the procedures outlined in Orange Municipal Code Section
17 10 070. The DRC will conduct a public meeting and make a determination on
the proposed project.
The Committee may approve, approve with conditions, deny or continue the project. A
continuation may be granted if the applicant is willing to make changes to the project as
recommended by the DRC. A DRC determination may be appealed pursuant to Orange
Municipal Code Section 17.08.050.
Larger or more complex projects may also require review by the Planning Commission and/
or City Council, depending on the review process required under the Orange Municipal Code.
If the project has the potential to significantly impact a historic property, it may also require
an associated environmental review process under the California Environmental Quality Act
CEQA). Staff will advise you of the required approvals. The following types of projects are
reviewed by the DRC and require a DRC determination:
Addition to a contributing or non - contributing building
Addition to a contributing or non - contributing accessory structure,
resulting in a structure larger than 120 square feet
Alterations to the roofline of any building
New accessory structure greater than 120 square feet
Demolition of contributing or non - contributing accessory structures
Demolition of a non - contributing building
Infill construction
Relocation of a structure
New signs or sign programs
Visibility from the street is determined by Planning Division staff. Generally,
visibility includes all portions of the front and side elevations that are visible from the
adjacent street or sidewalk. Areas that would be visible but are currently obscured by
landscaping are considered to be visible.
Demolition of any building requires Demolition Review under OMC 17.10.090. The
proposed replacement project must be reviewed at the same time as the proposed
demolition.
Building permits will be required for the majority of DRC projects and will only be issued
by the Building Division after approval by the DRC.
Exemptions: The following types of projects are exempt from the DRC or MDR process for
both contributing and non - contributing properties.
Interior alterations that do not cause a change to the exterior appearance of the building
Rear yard landscape or hardscape that is not visible from the street and does not involve
the removal of any historic features of the site
Minor front and side yard landscape projects, involving installation of new plantings.
This exemption does not apply to installation of new fences, walls or hardscape or to the
removal of mature trees. The City's Tree Preservation Ordinance protects mature and/
or historic trees from removal. If you are considering removal of a mature tree on private
property, please consult the Community Services Department to obtain a Tree Removal
Permit. If you have questions about maintenance or removal of a street tree, please
contact the Public Works Department
General maintenance or limited repairs to correct deterioration that does not involve
a change to the design or materials of the building and does not involve abrasive or
destructive cleaning methods
Exterior paint, where no paint is being applied to previously unpainted surfaces such
as masonry, stone or naturally finished wood
Summary of Common Project Types and Required Review Process
This table is a summary of typical projects and their required review process. However,
depending on the complexity of the project, staff may refer the application to the DRC for final
determination. Larger and more complex projects may also require additional review by the
Planning Commission or City Council under the Orange Municipal Code.

HOW TO PLAN FOR A SUCCESSFUL PROJECT USING THE HPDS
The following steps will help you navigate the process for projects reviewed
under the HPDS:
Become familiar with the Historic Preservation Design Standards.
Review the HPDS and determine which sections apply to the project. Be sure that you are
addressing all applicable design standards during project development.
2. Review the property's context and building's features.
After reviewing the HPDS, determine what are the character - defining features of the
property and how they will be affected by the project. Look at how the project will fit into the
neighborhood in which it is located. The project should address the design standards related to
both the context and the individual buildings on the property.
3. Consult with Planning Division staff.
We strongly recommend that you meet with staff prior to creating final drawings or submitting
an application. Staff can provide you with guidance to identify how your project meets or is in
conflict with the HPDS.
4. Engage professional design help.
You are encouraged to engage an architect with experience in historic preservation to assist
with the project. Working with a professional to develop a clear set of project drawings will
likely save time and money during the review process. While this is not required, it is strongly
encouraged for all projects.
5. Prepare and submit a complete application for review.
A DRC /MDR application must be submitted for all projects requiring review. The type
of application will depend on the scope of work. The application must provide enough
information to adequately understand the proposed project, and typically must include
drawings. The drawings should be to scale and clearly depict the work proposed.
6. Staff reviews the application.
For a MDR application, staff will review your application when you submit it at the Planning
Division Counter. If the information provided is complete and the project meets the HPDS, it
will be approved at the counter. For a DRC application, staff will review your application within
30 days of submittal. Depending on the complexity of your project, staff may request additional
information or revisions to the plans. Staff will schedule the project for a DRC meeting and will
make a recommendation to the Committee only after you have responded to comments and
your application has been deemed complete.
7. Attend the scheduled Design Review Committee meeting.
The Design Review Committee meets on a regular schedule established by City Council
resolution and available on the City website: cityoforange.org. You and any design
professionals who worked on the project should attend the meeting to answer questions and
comments from the DRC. You will receive a copy of the meeting agenda and staff report for
your project in advance of the meeting.

HISTORIC CHARACTER
The intent of the HPDS is to preserve the unique features of Orange's
established historic districts. The following is a summary of the character -
defining features of the Plaza Historic District and the Old Towne Historic
Districts (both local and National Register). These features are critical to the
significance of the historic districts and should be preserved as part of any
proposed project in the historic districts. These character - defining features
include specific aspects of setting, mass, scale, design and materials.
You should consult these lists to confirm that any project involving
rehabilitation or new construction retains these character - defining features.
The Cypress Street Barrio is not a separately designated historic district
but it is an important neighborhood within the Old Towne Historic
Districts. The barrio's cultural significance comes from its long- standing history
as the center of the Mexican and Mexican American community in Old Towne. Thi:
heritage is described in a separate section below.
Similarly, the Railroad /Packinghouse Corridor is not designated as a separate Plaza Park, ca.1915
historic district, but it reflects the character of Orange's early agricultural heritage.
The history and significance of the Railroad /Packinghouse Corridor is described in the
Santa Fe Depot Specific Plan. For design guidelines specific to historic industrial buildings
in this area, consult the Santa Fe Depot Specific Plan on the City's website.
Character- Defining Features of the Plaza Historic District
The Plaza Historic District is the original commercial downtown of Orange. The
late 19th and early 20th century buildings surround Plaza Park at the center of a
roundabout. Plaza Park was laid out in 1886 and retains its pattern of walkways
and landscape areas from that period. The fountain at the center of the park
dates to 1937.
Period of significance: 1871 -1931
Commercial district anchored by elliptical Plaza Park and round-
about street configuration at the intersection of Chapman Avenue
and Glassell Street
Buildings located at the sidewalk with no front or side setbacks
Dense, primarily two -story development with commercial
storefronts at the ground floor and office or residential uses above

Character- Defining Features of
the Old Towne Historic District
The Old Towne Historic District reflects the early
development of Orange. It includes the late 19th and
early 20th century business district around the Plaza,
surrounding residential neighborhood and industrial area
along the Atchison, Topeka & Santa Fe Railroad. The
Historic District includes a variety of architectural styles
in commercial, residential, institutional and industrial
buildings.
Period of significance: 1888 -1940

Cypress Street Barrio
The Cypress Street Barrio is a small historically significant neighborhood in the
northeast corner of the Old Towne historic districts. The neighborhood first
developed in the 1890s with construction of several fruit packinghouses along
the Atchison, Topeka & Santa Fe Railroad. The growth of the citrus industry
brought Mexican American workers and their families to the area to pick and
pack the flourishing crops. Early on, Mexican American families in the barrio
lived in older houses that were moved to the properties surrounding the
railroad. As the neighborhood developed, additional houses were constructed,
ranging from simple tenements to Queen Anne cottages and Craftsman
bungalows. The residences were interspersed with small businesses including
grocery stores, bakeries, tortillerias, restaurants, barbershops, pool halls, and
automobile shops, most owned and operated by the Mexican American families living in
the neighborhood. Faced with segregationist policies and attitudes from the white residents
of Orange, the barrio's residents developed a rich tradition of institutions to support the
neighborhood, including The Friendly Center which provided healthcare, homemaking
classes and childcare to residents and jamaicas, or church street fairs held on Cypress Street.
Adapted from the Cypress Street Barrio Historic Context Statement by Chattel, Inc.)
Bounded approximately by Rose Avenue to the north, Glassell Street to the east, Almond
Street to the south, and the Atchison, Topeka & Santa Fe railroad to the west
Packinghouses and other industrial buildings along the railroad. Development
was closely tied to the citrus industry and the Mexican American workers
who supported the industry
Primarily one story residential buildings in a variety of early 20th
century architectural styles. Features of these houses are similar to
the rest of the Old Towne Historic District
Small number of commercial buildings that housed small
businesses or institutions serving the neighborhood. Important
examples include:
Luna's grocery store at 418 N. Cypress Street
The Friendly Center at 424 N. Cypress Street
Cypress Street School at 544 N. Cypress Street and Killefer
School at 541 N. Lemon Street

Architectural style sheets with information on common types of historic residential
architectural styles in Old Towne are available on the City's website or at the Planning
Division Counter at the Civic Center. Please consult these style sheets when you are planning a
project to ensure that any changes preserve the historic character of the property.
16
STANDARDS FOR HISTORIC BUILDING FEATURES
The following standards address the treatment of specific elements anc
features of a historic building. These standards apply to all building
types, whether residential, commercial, institutional, or industrial.
Roofs
The roof is a major character- defining feature for most historic
buildings. Similar roof forms repeated on a street help to create a
sense of visual continuity for the neighborhood. Roof pitch, materials,
size, orientation, eave depth and configuration are all distinct
features that contribute to the overall integrity of a historic roof. The
13 location and design of chimneys as well as decorative features such as
dormers, vents and finials are also often character - defining roof features.
Certain roof forms and materials are strongly associated with particular
architectural styles, and altering roof shapes or materials may impact the
integrity of the historic building. Care should be taken to ensure that the
character of the roof is retained.
I . The historic roof shall be preserved and maintained.
a. Changing the slope or orientation of a historic roof is inappropriate.
b. The depth of the eaves is an important character - defining feature of a historic building and
should be preserved. Adding fascia, cutting off exposed rafter tails, or boxing in exposed
rafters is inappropriate.
c. Other important historic roof details include vents, corbels, dormers, finials and built -in
gutters. These elements should be preserved and repaired as necessary.
2. Specialty historic roofing materials shall be preserved.
a. Deteriorated sections of specialty historic roofing materials, such as clay tile, may be
replaced with materials that exactly match the historic materials.
3. Replacement roofing materials should be substantially similar in scale, texture,
and color to materials used historically.
4. New dormers should not be added to elevations that face the street.
5. New skylights should not be added to elevations that face the street.
a. New skylights must be flush with the roof plane.
b. New roof vents should be low profile and coordinated with the color of the roofing material.

Windows and doors are essential components of
the character of a historic building. The placement,
grouping and size of historic openings on each
elevation are important parts of each building's
architectural style. The construction and materials
of each window or door are also integral to the
building's character. Because windows and doors
are so critical to the character of a historic building,
they generally should not be replaced. Replacement
is only appropriate where the window or door is too
deteriorated to be repaired. To maintain the character
of the historic building, the replacement must exactly
match the original in dimensions, materials and
details, which often requires building custom windows
or doors. Maintaining historic windows and doors is
often the most cost - effective method to preserving
the character of your home while improving energy
efficiency. The windows and doors in your home
may be more than 100 years old and, with regular
maintenance, can outlast modern replacements.
Historic windows and doors shall be preserved and
maintained.
Do not alter the location, number, size, pattern,
or proportion of historic windows and doors on
elevations visible from the street.
Enclosing a historic opening or adding a new
opening on elevations visible from the street is
generally inappropriate.
c. Historic grillwork on windows should be retained.
New security bars should not be added to
c
windows or doors on street - facing elevations.
d. Simple screens that are compatible with the
architectural style of the building are appropriate.
Typically, wood frame screens will be most
compatible with houses in the historic district.
Clear anodized aluminum screens are generally
not appropriate.

e. Awnings and shutters should only be used where they are compatible with
the architectural style of the building. They should be similar in materials,
design, and operation to those used historically and should
match the shape of the window on which they are installed.
2. Historic windows and doors with signs of damage or
deterioration shall be repaired, rather than replaced.
a. Repairs should follow the recommendations of NPS
Preservation Brief 9 — The Repair of Historic Wooden
Windows and other applicable technical guidance from
NPS Technical Preservation Services. See Appendix B for a
complete list of Preservation Briefs.
71 b. If glass in historic windows or doors must be replaced, clear
glazing is appropriate. Reflective coatings or dark tints are
not appropriate. Limited use of frosted or opaque glass may
be appropriate on side or rear elevations, if privacy from
adjacent properties is a concern.
3. A historic window or door that is beyond repair may be
replaced in kind.
i
AWNING
CASEMENT

Typical window styles
a. The replacement window
or door should match the
size, shape, arrangement of
panes, materials, method
of construction and profile
of the historic feature.
b. The replacement window or door will likely need to be
custom -made to match the historic design and materials.
4. Restoring original windows and doors that have been removed
or altered is encouraged.
a. If a window or door has been replaced with non - historic
materials, a new window or door that is compatible with
the architectural style of the building may be installed
in its place. Design of the replacement should be based
on historic photographic evidence. If no such evidence
exists, the replacement should be based on a combination
of physical evidence (indications in the structure itself)
and evidence of similar openings on the building and on
buildings of the same architectural style. The new window
or door should reflect the size, shape, materials, and
arrangement of panes of historic features.
21
Architectural details and building materials are key to each historic building's
character. The characteristics of primary building materials, including the
scale, texture and finish, and features such as lintels, brackets, cornices
and columns, also contribute to a particular architectural style.
Decorative details should be maintained and repaired to enhance
their original character. Regular maintenance of these features
will prolong the life of the historic building. Repairs may include
stabilizing or consolidating deteriorated portions of the historic
materials. These options should be carefully considered before
an architectural detail is replaced.
1. Historic architectural details and building materials shall be
preserved.
a. Regularly check historic materials for conditions such as
moisture accumulation that can cause deterioration.
b. Do not remove historic materials that are in good condition.
i. All materials weather over time and a scarred or uneven
surface does not mean that a particular building element
is too deteriorated to be preserved.
C19
ii. Materials that show signs of age are part of the
character of historic buildings.
c. Distinctive architectural features and
examples of skilled craftsmanship are
particularly important to the character
of a historic building and should receive
sensitive treatment. Distinctive features
may include decorative elements, such
as brackets, exposed rafter tails, and
columns, or the pattern of materials
used in construction, such as decorative
shingles or masonry. Removing or
covering these details is inappropriate.
d. Do not alter historic finishes. Unpainted
historic masonry or wood elements should
not be painted. Similarly, wood elements
that were painted historically should have
a painted finish to protect the materials
from deterioration.

2. Historic materials shall be repaired in place
to the greatest extent feasible.
a. Repairs should maintain as much historic
material as possible by patching, splicing
and consolidating deteriorated materials.

b. Materials that can be repaired in place
should not be removed or replaced.
c. When cleaning or repairing historic
materials, use the gentlest means
possible.
3. Historic materials that are too deteriorated
to be repaired shall be replaced in kind.
a. Replacement is a last resort when historic
materials cannot be repaired.
b. Replacement should be limited to only
those portions of the historic elements that
cannot be repaired. For example, complete
replacement of a window is not appropriate
if only the sill is deteriorated beyond repair.

historic materials
c. Replacement elements shall match the
historic design, materials, scale, size,
proportion, finish, texture, details, profile, reflectivity, and durability.
d. Synthetic replacement materials, such as vinyl siding or synthetic stucco,
are not appropriate for use on a historic building.
e. Replacement of a historic material with an alternate material may be
considered in limited circumstances.
i. The proposed alternate material will be evaluated using the criteria
described in National Park Service Preservation Brief 16: The Use of
Substitute Materials on Historic Building Exteriors.
ii. The applicant will provide justification for the use of an alternate
material including information on the availability and performance
of an in -kind replacement material. The applicant will also provide
samples and specifications of the proposed alternate material,
including information on performance and durability.

24
4. Removing non - historic features where possible is encouraged.
a. In some cases, these later additions may be obscuring original historic materials
that can be recovered.
5. If historic features are missing, replacement should be based on historic
documentation. If historic photographs or physical evidence, such as remnant marks on
the structure, are not available, the design of replacement details should be based on
similar elements on buildings of the same architectural style in the neighborhood.
6. Adding architectural details or elaborate decorative elements that are not appropriate
to the architectural style of the building or are not clearly based on evidence from the
building's history should be avoided.
7. Paint colors that are appropriate to the period and style of the building are strongly
encouraged.
Mechanical Systems
Mechanical systems help to adapt historic buildings to contemporary uses. With careful
planning, most can be located where they cannot be seen from the street and will not detract
from the character of the historic district.

b. Roof- mounted equipment is only appropriate on flat roofs with existing
parapet walls to fully screen the equipment.
c. Satellite dishes and similar equipment shall be located in areas that are least
visible from the street.
d. Ground - mounted or building- mounted equipment shall be appropriately
screened from view from the street.
2. Solar panels shall be located in areas that are least visible from the street.
a. Rooftops of detached garages or rear - facing roofs of primary buildings are
the most appropriate locations for solar panels.
T On flat roofs with parapet walls, solar panels may be installed on the full
extent of the roof, provided that the panels are not visible above the
parapet walls.
c. On sloped roofs, solar panels shall be installed on the rear
50 percent of the roof of the primary building.
d. On corner lots, for buildings with sloped roofs, solar
panels shall be installed on the interior 25 percent of
the roof of the primary building.
e. If the permitted locations for solar panels in Standard
2c or 2d cause the installation to be visible from
the street, staff may require the proposed system to
be modified to reduce its visibility. The modification
shall not significantly increase the cost of the system or
significantly decrease its efficiency, as defined by California
Civil Code Section 714.
f. Solar panels shall be parallel to the roof plane, shall not
extend more than 10 inches above the roof surface, and shall
not overhang or alter existing rooflines.
g. Solar panels shall be attached to roofs using the least
invasive method possible, without damaging historic
features.
h. Solar panels shall be neatly arranged in a rectangular format
with no gaps between the panels.

STANDARDS FOR HISTORIC RESIDENTIAL BUILDINGS
These standards apply to single - family structures, multi - family structures,
and structures that were originally constructed for residential use and
have since been converted to other uses. The Standards for Historic
Building Features also apply to all historic residential buildings.
Setting
The setting, or streetscape, is a critical component of the sense
of place that is important to historic districts. Front yards in historic
residential neighborhoods are typically characterized by a progression
from the public street to private interior spaces. Streetscapes frequently
have common front and side yard setbacks shared by the majority of buildings
on the block. Preservation of this streetscape pattern is essential. The
streetscape includes the visual character of the street, sidewalks and walkways,
buildings, landscape, and street lighting working in concert. Relationships
of buildings to each other, setbacks, fencing patterns, views, driveways,
walkways, lighting, and street trees all contribute to the character of historic
streetscapes.
1 - The prevailing pattern of open space in the front and side yards of
contributing properties should be preserved.
2. Historic walkways, driveways, and other hardscape features in the front yard
shall be preserved.
a. Unpainted historic walls, curbs, or planters should not be painted.
Landscaped parkways and
front yards flanking the
sidewalk create a pleasant
place to walk
3. Repairs or expansion of paving or hardscape features should match the historic
features in materials, color, texture, and finish.
a. The appropriate concrete paving material for driveways or walkways is a natural
grey concrete, textured to expose the fine aggregates through an acid wash or
light retardant finish.

Alternate paving materials in front or side yards visible from the street may be
considered, if they are compatible with the building and the streetscape.
Parkways, front yards, and side yards should be reserved for landscape. Paving
or non - porous surfaces should be minimized.
Parking areas should be located at the rear of the site and should be screened from
public view by appropriate fencing or landscaping.
Widening an existing driveway is generally not appropriate.
Driveways between 9 and 12 feet are generally appropriate and
provide adequate room to maneuver vehicles.
Driveways may have a center planting strip. The planting strip
should be a minimum of 18 inches wide.
Front yard fencing may be installed, provided that it matches
the prevailing pattern of fencing in the streetscape.
Front yard fencing should be low and transparent, using
materials that are in keeping with the character of the house.
Wrought iron fences may be appropriate for Spanish Colonial
Revival or Tudor Revival houses.
Wood picket fences may be appropriate for Craftsman or Folk
Victorian houses.
Utilitarian wire and wood or steel post fences were frequently
used during the historic districts' period of significance
and are an appropriate style for new front yard fencing.
Solid masonry walls in the front yard are generally
not appropriate.
The use of a traditional color palette is
encouraged.
g. Front yard fences are strongly encouraged to have
an 18 -24 inch planting strip between the sidewalk
and the fence.
8. Rear yard opaque fencing for privacy may be
appropriate, provided that the design and materials are
compatible with the building and the neighborhood.

a. If a six foot rear or side yard fence is located next to
the street, it is strongly encouraged to have a 24 inch
planting strip between the sidewalk and the fence.
9. Vinyl, chain link, and plastic fences are prohibited.
10. Mature trees and hedges should be retained
whenever possible or replaced with matching
plantings as necessary.
11. Drought tolerant alternatives to lawns may be
appropriate if the alternatives are compatible with the
character of historic front yards and parkways. Front
yards are generally characterized by low- growing lawns
with foundation plantings at the base of the buildings or
cottage gardens with a variety of plantings. Low -water
alternative plant species appropriate to the climate may be
used, if they are compatible with the historic character of
front yards and parkways. In areas visible from the street,
yards that are primarily gravel, mulch or unplanted soil are
generally not compatible.
Compatible drought - tolerant landscape
12. Artificial turf is prohibited in parkways, front yards, and side yards visible from the street.
Porches
In residential neighborhoods, porches function as an outdoor
living space and a sheltered transition into the house.
The various components of porches, including steps,
balustrades, columns, pilasters, doors, and cornices, and
decorative embellishments, add to the character of
historic neighborhoods and help to establish a sense
of community. Porches are often a primary character -
defining feature of a historic house.
1. Historic porches shall be preserved.
a. Maintain the location, shape, details, posts,
railings, balustrades, and decorative brackets of the
historic porch.
b. Repair deteriorated decorative elements or replace
missing elements to match the existing.

c. Alterations for accessibility should be designed and built
to be minimally visible and to require minimal alterations to Historic porch with turned
historic materials, while allowing equal access to the building. wood columns
29
Front porches in Old Towne have a variety of piers and columns, all
Historic porches may include rear or side service porches, which are typically
characterized by a wood -sided half wall with a band of windows above. A service
porch might look like an addition because it may have a different roof line than the
house. These porches usually started as screened indoor - outdoor spaces early in
the building's history and have been gradually enclosed over time. Intact service
porches are character - defining features and should be preserved.
2. Original steps should be preserved. If the steps are so deteriorated that they
must be replaced, they should be replaced utilizing compatible materials.
a. In general, wood steps are appropriate for a wood porch and
concrete steps are appropriate for a concrete porch. However,
other combinations do occur on contributing buildings.
All or part of a historic porch or entrance should not be enclosed in
areas visible from the street.
In many cases, historic porches did not include a guardrail, and one should
not be added unless there is evidence that a guardrail existed on the porch
historically or there is a safety issue to be addressed.

5. The addition of a handrail for safety at the front steps may be appropriate, if the handrail is
simple in design and uses materials compatible with the historic building.
6. If porch posts have been replaced with non - historic or non - compatible materials,
replacing those elements to match the historic building in scale, proportion
and materials is encouraged.
a. The design of replacement porch posts should be based on historic
photographs, physical evidence, and study of buildings with a
comparable architectural style.
7. New wood posts, handrails, and guardrails should use concealed
fasteners.
Garages and Accessory Structures
Many historic properties in Old Towne contain small accessory
structures in the back yard. These structures are typically utilitarian
carriage houses, garages or sheds, constructed to store equipment or
vehicles. Some accessory structures reflect the architectural style
of the house, but many are simple wood frame structures with
modest architectural details and materials. In many cases, these
structures reflect the development pattern of the late 19th and
early 20th centuries in Orange. The historic resources survey
form for a property may not identify accessory structures
as historic features of the site. However, these structures
may be character - defining features of the historic property
and contribute to the character of the historic district. The
following criteria will be used to determine if an accessory
structure is a character - defining feature of the property. If an
accessory structure:
1) was constructed during the Historic District's period of
significance (1888- 1940); and
2) retains physical features from that time period
Then it is likely a character- defining feature of the
property and should be preserved. If you would like
to find out if an accessory structure on your property
may be a character - defining feature, please provide the
City's Historic Preservation Planner with photographs of
the structure.

b. A one story addition to the side or rear of an accessory structure may be an
appropriate way to provide additional parking or storage area.
c. The addition of a new second floor or substantial modifications to the rooflines of
garages or accessory structures are inappropriate.
d. Adding small dormers to an existing roof may be appropriate, provided that the scale,
design and materials of the dormers are compatible with the historic accessory structure.
d. Historic garage doors are typically utilitarian wood doors that swing open or slide on a metal
track. If the accessory structure has a historic garage door, it should be preserved.
i. A replacement of a non - historic garage door should be compatible with the materials
and design of the historic accessory structure. A roll -up sectional door may be
appropriate if the design and materials are compatible with the historic structure.
2. In limited cases, a historic accessory structure may be relocated on the property.
a. If relocation of a historic accessory structure is proposed, the structure must remain intact
during the relocation. A qualified structural engineer or house mover shall provide a plan
for bracing and relocation of the structure to ensure that it can be relocated intact and with
minimal loss of historic material.
b. The new location of the accessory structure on the lot shall maintain the historic relationship
between houses and accessory structures that are typical of the Historic District. Relocation
shall not substantially change the prevailing development pattern of houses and accessory
structures in the neighborhood. In general, accessory structures should be relocated within
rear yards only and should not be relocated in front of the house.
32
c. Relocation shall maintain the original orientation of the structure to the street.
d. Relocation should retain the existing driveway to the greatest extent feasible.
3. The majority of historic accessory structures can be preserved and rehabilitated.
In limited cases, a historic accessory structure may be too deteriorated to be
repaired. If a property owner believes that a historic accessory structure
cannot be repaired, the property owner may submit a report to the
Historic Preservation Planner requesting demolition and reconstruction
of the structure.
a. The report shall include:
i. A detailed analysis of the condition of the existing
structure and feasibility of repairs by a qualified structural
engineer and /or historic preservation contractor.
ii. A comprehensive proposal for accurate
reconstruction and reuse of salvaged historic
materials from the structure.
b. The report will be reviewed by the Historic
Preservation Planner who will make a
recommendation to the Design Review
Committee on the proposed demolition and
reconstruction.
c. The request for demolition of a historic
accessory structure shall comply with the project
review process outlined in the Demolition Review
Ordinance (OMC 17.10.90).

structures in the historic districts.
a. A garage attached to a historic house is generally inappropriate. New garages
and accessory structures typically should be located behind the rear wall of the
historic house.
b. New garages or accessory structures should not compete visually with the historic
residence and should be subordinate in height, width, and area in comparison to
the existing primary structure.
similar materials, windows, roof patterns, and simplified architectural details.
Basic rectangular forms, with simple hip or gable roofs, are appropriate for most
new garages and accessory structures.
e. Single -bay garage doors are more appropriate than double -bay garage doors on
new structures.
STANDARDS FOR HISTORIC COMMERCIAL BUILDINGS
The following standards apply to existing commercial structures and structures
that were originally constructed for commercial use and have since been converted
to other uses. The Standards for Historic Building Features also apply to all historic
commercial buildings. Both the Historic Preservation Design Standards and the Santa Fe
Depot Specific Plan Design Guidelines apply to historic industrial buildings.
Setting and Building reatures
The Old Towne Historic District includes several commercial areas with distinct character.
The Plaza Historic District is the earliest commercial center in Orange. It consists primarily of
the properties fronting Glassell Street and Chapman Avenue one block around Plaza Square.
These properties create a continuous street face with zero setbacks from the sidewalk. Large
storefronts on the ground floor are oriented toward pedestrians with offices or apartments
above. Parking areas are located at the rear of buildings.
The Downtown Core encompasses eight blocks around the Plaza bounded by Maple
Avenue on the north, Grand Street on the east, Almond Avenue on the south, and Lemon
Street on the west. The perimeter blocks of the Downtown Core provide a transitional space
between the taller, denser development of the Plaza and the surrounding residential

streets contain historic residential buildings converted
to commercial uses. These properties retain their
residential character with landscaped front and side
yards and modestly sized buildings. Rear yards may have

STOREFRONT WINDOW
Storefronts
One of the most important character- defining features of a
historic commercial building is the storefront. Although storefront
character varies from building to building, there are specific features
common to almost all storefronts. The most typical historic
storefront configuration consists of a low base wall, known as a
bulkhead, topped by large panes of glass, or storefront glazing.
The main store entrance is located in the center or to one side
of the storefront, often recessed from the main facade. Often,
storefronts will include a second, less prominent door leading to
second story offices or apartments. Above the storefront glazing,
there is often a band of narrow, horizontal panes known as
transoms or clerestory glazing. The store's signage was historically
located on awnings over the storefronts, was painted on the glass
itself, or was located in a sign area above the clerestory or transom
glazing.
Historic commercial storefronts and their component elements,
such as display windows, bulkheads, transoms, prism glass, doors,
pillars, and pilasters, shall be preserved.
a. Do not alter the location, number, size, pattern or proportion
of historic openings, particularly on primary elevations.
b. Interior spaces should be designed so that new partitions do
not impact the appearance of the historic storefront.
2. Transparent, clear
glazing is appropriate
for ground floor
storefronts. Reflective

rances at new storefronts shall be used in the Plaza
ict and are encouraged in other locations.
fronts in the Plaza and Downtown Core should maintain
sting pattern of glass at the building wall along the
Jewalk. Removing storefront glazing to create recessed
outdoor areas at the front of commercial buildings is
generally discouraged and will only be appropriate
if the building is a non - contributor to the Historic
District or if the building has a documented
history of a recessed storefront in that location.
Security bars or roll -down gates are
prohibited.
Awnings should be similar in materials, design,
and operation to those used historically.
An awning should typically fit within each of the
building's structural bays, exactly over the display
windows.
Internally illuminated awnings or vinyl awnings are
prohibited.
c. New awnings shall use anchors and attachments that do not damage the historic
building materials and /or structure.
6. Reconstructing historic storefronts that have been removed or
altered is encouraged.
If a historic opening has been replaced with non - historic
materials, a new one that is compatible with the
architectural style of the building may be installed
in its place. Design of the replacement should
be based on available photographic evidence. If
no such evidence exists, the replacement should
be based on a combination of physical evidence
indications in the structure of the building) and
evidence of similar elements on buildings of the
same architectural style in the historic district. The
new opening should reflect the size, shape, design and
materials of similar openings.

STANDARDS FOR NEW CONSTRUCTION RELATED
TO HISTORIC BUILDINGS
Additions
A small addition may be an appropriate way to encourage
contemporary uses of a historic building. A thoughtfully designed
addition will have limited impacts to the streetscape of the historic
district and the materials of the historic building. The compatibility of
an addition is based on a number of elements related to mass, scale,
design, materials and detailing. If you are considering an addition to
your historic building, please contact Planning Division staff early in the
design process to discuss opportunities and constraints related to new
construction in the historic district.

a. If the addition were removed in the future, the essential form and integrity of the historic
building should be unchanged.
b. The roofline of the historic building should be retained on elevations visible from the street.
Infill Construction
Infill in historic districts may consist of constructing a new building on a vacant lot (primary
building) or constructing additional buildings (secondary buildings) on a lot containing
an existing building. Successful infill construction takes cues from the surrounding historic
neighborhood and its buildings without creating an exact replica of a historic architectural style.
New construction should be consistent with the mass, scale, materials, height, roof form, setbacks,
and pattern of windows and doors of existing buildings on the street. The site design of an
historic structure is an essential part of its character. The spacing and location of buildings on each
lot within an historic neighborhood usually establishes a rhythm that is essential to the character
of the neighborhood. The grouping of buildings, with uniform setbacks and street features, gives
each neighborhood a strong sense of place. One of the first steps to designing an infill building
is to look at other buildings on the block and determine what are the common design elements
that create a consistent streetscape and neighborhood character. Contemporary interpretations of
historic architectural styles are not discouraged, but the primary goal of infill construction should
be to create a building that responds to its context within a historic neighborhood.
1. The location of new primary and secondary structures on a lot should be consistent with the
historic pattern of front and side yard setbacks.
2. New buildings should be similar in mass and scale to surrounding buildings.
a. If a new building is larger than its neighbors, it should be modulated so that the
appearance of the mass is located back from the street and is less visible.
b. Properties with new construction are recommended to use the average Floor Area Ratio of
historic properties on the surrounding street as a model for compatible new development.
See the description on the following page for instructions on determining an appropriate
Floor Area Ratio for your project.
3. The height and roof form of a new building should be comparable to surrounding historic
buildings.
a. Roofing materials and details should be similar to those found on historic properties.
b. Dormers should be similar in size and style to historic properties.
46
6. Window and doors openings in an addition should reflect the size, shape, and pattern of
4. A new primary building should have a main entrance and fagade
parallel to and facing the street.
5. The progression of public to private spaces from the street should be
maintained.
A sheltered building entrance or front porch may be appropriate
to create a transitional space from the street to the interior of the
building.
b. New construction should have a similar pattern of windows and doors
on elevations visible from the street to those found in surrounding
historic buildings.
7. The use of traditional building materials found on historic buildings in
the Historic District is encouraged for new construction.
Exterior materials shall be compatible with the size, scale, design, texture,
reflectivity, durability and color of historic materials used on comparable historic
buildings in the Historic District.
b. Use of simplified versions of traditional architectural details is encouraged.
c. Alternates to traditional building materials may be considered, if the alternate material
is compatible with the design and appearance of comparable historic features on
similar contributing buildings in the Historic District.
8. The height, mass and scale of new secondary buildings should be minimized as much as
possible.
a. In general, secondary buildings should be no taller than the primary building. In
limited areas, secondary buildings may be taller than primary buildings, if this

the character of the neighborhood.
Non - contributing properties shall comply with the
Standards for Historic Residential Buildings — Setting or
Standards for Historic Commercial Buildings — Setting.
2. Non - contributing properties shall comply with the Standards
for Historic Building Features — Mechanical Systems.
