EXHIBIT A
Section 30 -23,1 Traditional Neighborhood Design Overlay
(A) Purpose
Traditional Neighborhood Overlay Districts are established to foster strong, vibrant traditional neighborhoods that
consist of well- maintained historic homes and well - designed, architecturally compatible new residential
construction. Such districts are to be applied in neighborhoods with homes and residences mostly constructed
before 1950.
Therefore, the purpose of the Traditional Neighborhood Overlay District is to implement minimum design
standards intended to maintain the unique architectural qualities and features of Oshkosh's older traditional
homes; ensure coordinated, compatible design between existing and new homes; minimize adverse impacts on
adjacent properties from buildings that may detract from the character and appearance of the district as a whole;
and, create strong neighborhood identities and cohesive design through historic home preservation and well -
designed, high quality new construction and site design. New residential construction shall be compatible in
Character with homes in the immediate vicinity, considering scale, style and materials. The Overlay District also
seeks to stabilize and increase neighborhood property values and instill a sense of "pride of place" among
residents and property owners.
(B) Overlay Location
(1) Areas that may be deemed suitable and appropriate for a Traditional Neighborhood Overlay District shall:
(a) Include a grouping of single and/or two - family homes generally constructed prior to 1950 that retain
traditional character of their building styles including, but not limited to, Greek Revival (1830 - 1850),
Gothic Revival (1850 - 1895), Italianate (1856- 1885), Mansard or French Second Empire (1860- 1880),
Stick (1870 - 1890), Queen Ann Revival (1880- 1900), Shingle Style (1885- 1902), Richardsonian
Romanesque (1880 - 1900), Prairie School (1900 - 1920), Craftsman (1900 - 1920), American Foursquare
(1900- 1920), Bungalow (1900- 1940), Tudor Revival (1920s), Colonial Revival (1920 - 1940), Georgian
Revival (1900 - 1930), and Mediterranean (1920s).
(b) The Traditional Neighborhood Overlay District is not intended to be applied to areas where there is no
established architectural character or where the areas building character has been so substantially
altered by modern development (post 1950s) or redevelopment (i.e. housing stock that has been
significantly altered from its original design or has deteriorated to an extent that the styles are no longer
identifiable)
(c) Consist of a minimum area of not less than a block
face (both sides of the street) from intersecting
street to intersecting street. Once the minimum
area is established, additional properties may be
added as deemed appropriate.

(C) Administration and Enforcement
The Director of Community Development, or designee, shall serve as the Administrator of this Overlay Code.
The Administrator shall enforce the provisions of this Code. A Traditional Neighborhood Overlay District may be
adopted through a zoning map amendment as a standard overlay district of itself or the. overlay district can be
used as a model code as a base for the development of a hybrid /modified design standard overlay through the
adoption of a Planned Development Overlay District.
(1) Adoption Process. Upon receipt of a request to consider application of the Traditional Neighborhood
Overlay District or Planned Development Overlay District to an area of the city, an informal review of the
area of -the proposed overlay will be conducted by the Department of Community Development and if
deemed appropriate, a zoning map amendment request and formal review shall be forwarded to the Plan
Commission and Common Council for consideration and action.
The Plan Commission shall review a request for the overlay designation and make a report and
recommendation of denial, approval, or approval with modifications it may deem appropriate to the Common
Council. The Common Council shall act to deny, approve, or approve with modifications any request for the
overlay designation before them for consideration.
(2) Exceptions and Appeals
(a) Exceptions. Exceptions to the building architectural standards set forth in this Section may be granted
by the Director of Community Development, or designee, to permit substitute building materials or
construction methods of comparative quality or design when it can be demonstrated that the provisions
of this Section are infeasible and that the granting of such exception is in keeping with the spirit and
intent of this Section. Decisions rendered by the Director of Community Development or designee may
be appealed to the Plan Commission.
(b) Appeals. The Plan Commission is authorized to grant variances from the strict application of the
standards within the Overlay and an application for an appeal may be made to the Plan Commission
when it is claimed that the intent of the standards in the Overlay have been incorrectly interpreted; do
not apply; or their enforcement cause unnecessary hardship.
(D) Existing Buildings. Windows and Doors
(1) Purpose
The purpose of this section is to manage design changes to the windows and doors of existing traditional
residential homes in overlay districts established by this Section. Along with their primary function of
providing adequate light, ventilation and access to a home's interior, windows and doors contribute
significantly to a house's overall visual proportions, and image and appearance. Original windows and
doors shall be maintained wherever appropriate and technically feasible. New windows and doors shall also
be visually and functionally compatible with the home's architectural style and other character - defining
features.
(2) Applicability
(a) Existing Buildings — The regulations contained in this section of the Overlay Code shall be applicable to
changes to existing buildings front or side facade wall surface. In order to ensure that major changes
and additions to existing buildings are compatible with the surrounding neighborhood, any change or
addition within these districts after the effective date of the Overlay shall be subject to the regulations
contained in this section.

Elements of a typical double-hung window
wall. Doors may be single or double
depending on . the doorway opening and
configuration. Typical door and doorway entrance features include the door, frame, threshold,
transoms, sidelights, and any decorative surround casing or molding. The door itself may be full
paneled with no glazing panes (lights), half or quartered - paneled with lights, or fully lighted. A door may
also be accompanied with storm door that may be constructed in wood, metal, fiberglass, polyvinyl
chloride (PVC), high density polyurethane (HDPE) or wood composite. Storm doors are typically half or
fully glazed or screened.

(c) Front and Side Yard Elevations. A front elevation is
defined as the house wall /facade facing a street. A
corner side yard elevation is defined as a side or
secondary elevation that faces a street and an interior
side yard elevation is defined a secondary elevation
facing an internal lot line .
(d) Primary House Entrance. A primary house entrance is
defined as the main entrance located on a front or corner
side elevation that is visible from the public right -of -way
and originally designed for day -to -day ingress and
egress.

(4) Windows
(a) Window. Casings, Trim Work, and Crown Moldings. Casing, trim work, sills, and crown moldings
around windows and doorways are significant character - defining and decorative features for traditional
homes. They may also provide certain structural functions and protect against water and weather
infiltration around windows. The loss of such features can have considerable impact on a home's visual
appearance and functional operation.
(i) Existing Trim Work. Windows casings, sills, trim work
and crown moldings original to the house and existing.
on front or side facades/elevations shall be repaired
and not be removed and replaced unless there is
evidence of missing trim work and/or they are
significantly deteriorated and beyond feasible repair.
Significant deterioration is defined as extensive and
substantial cracks, holes and rot that have
compromised the trim work's or crown molding's
integrity. All casing and trim work shall be maintained
by filling all cracks and holes and repainting when
necessary.
Existing trim work and casings shall be
maintained wheneverfeasible
(ii) Replacement Trim Work. For. windows on the front or side facades/elevations, replacement trim
shall ideally be made of the same materials as the original trim work. Therefore, wood trim shall be
replaced by new wood trim wherever appropriate. Substitute materials may include fiber - cement,
vinyl, laminated veneer lumber, hardboard, high density polyurethane (HDRE) and other plastic -
wood products. The size (width and height) and profile of the replacement trim shall match the size
and profile of the original trim work where feasible. If no original trim work remains intact, the size
and profile of new trim work shall be compatible with other trim work found on the house or the
house's overall architectural style and visual appearance. If all trim work and casing are to be
replaced, replacements that are consistent in details /type shall be used for all windows.
(iii) Window Sills. Window sills shall only be replaced if there is evidence of significant deterioration. A
wood window sill is considered in deteriorated condition if it has extensive cracks, holes and decay,
and is not sloped away from the building to shed water. Replacement window sills shall be
replaced with similar or other compatible materials and have a drip on the bottom that prevents
water from entering the building under the window assembly. If all window sills are to be replaced,
new replacement sills shall be used for all windows.
(b) Existing Windows. Existing windows on front or side facades/elevations shall be maintained whenever
feasible and not replaced unless there is evidence of significant deterioration or cannot be feasibly
repaired. Significant deterioration is defined as extensive cracks or material rot in window jambs, rails
and muntins. Missing window hardware will not be considered in assessing a window's condition.
(c) Window RT placement. A replacement window on a front or side facades/elevations shall use the
existing window opening and match the original window's height to width dimensions wherever feasible.
A 5 to 10 percent variation in the height -to -width proportion is allowed if standard sized replacement
windows cannot fit into an existing window opening.
City of Oshkosh Traditional Neighborhood Design Oveday 2 -7 -2014 Page 4 of 23
(i) Replacement Window Style and Placement
Patterns. A replacement window's style
refers to the window's operation and
framing (i.e., one over one, double - hung),
materials and glazing (lighting) pattern. In
general, a replacement window shall be
appropriate and compatible with the style of
the original windows and the house's
overall architectural design features.
Replacement windows shall also match
original window placement patterns and
arrangements; for example, if the original Double Hung casement
windows were grouped in 2's or 3's,
replacement windows shall maintain this pattern.
(ii) Replacement Window Framing Options. The first window replacement option is a sash -only
replacement where the existing window frame, sill and exterior trim are maintained and in
good condition. This option is preferred before others are considered. if this option is not
feasible due to significant deterioration of the window frame, block frame replacement
windows are recommended for original recessed windows; nail -in frame replacements for
windows flush with the exterior walls. These frame types are more appropriate in maintaining
the original window profiles on front or side facades/elevations.
(iii) Replacement Window Materials. Replacement window materials shall match the original (i.e.,
wood for wood, metal for metal). Suitable alternative materials include aluminum, aluminum -
clad, fiberglass, steel, vinyl and vinyl -clad windows.
(iv) Replacement Window Operation. For front or side facades/elevations, replacement window
operation shall match the original (i.e. double -hung for double -hung; casement for casement,
etc.) Changes in window operation types are allowed on rear elevations that can't be viewed
from the public right -of -way.
(v) Window Pane Glazing/Lights. A
window's glazing or "divided
light" grid or muntins pattern
provide texture and character to
a building's architectural style
and visual character.
Replacement windows shall
match the original divided light
pattern with "true" or "simulated"
lights with the gridslmuntins
placed on the outside of the
window at a minimum.
City of Oshkosh Traditional Neighborhood Design Overlay 2 -7 -2014 Page 5 of 23
(vi) Storm windows. Storm windows in wood and other substitute materials are acceptable as long
as they match or are compatible with the window's operational configuration (i.e., double or
single -hung for double -hung windows). Substitute materials may include vinyl, aluminum,
metal, wood composite and other plastic -wood products.

Storm - single pane
Typical storm window types
(vii) Shutters. Wood, wood composite and PVC shutters may be used for new shutters. Shutters
shall relate directly to the size of the window. They may be either operable or fixed and shall
be provided with operable hardware (hinges and holdbacks) in either case.
Shutters - acceptable
Shutters - Discouraged
Acceptable and discouraged shutter sizes
(5) Doors
(a) Existing Doors and Entrances. Existing doors and entrances are key architectural and visual features
contributing to the character of most building's front or side facadeslelevations. Original doors and any
surrounding casing, trim work, thresholds and other features shall be retained and repaired unless
significantly deteriorated. Significant deterioration may be defined as large cracks or rotting materials
and features.
(b) Door Replacements. if a door cannot be repaired and must be replaced, the new door shall match the
style of the building and the original door wherever feasible.. The original material is preferred for
replacement doors but composite materials or metal doors are also acceptable. Replacement doors
shall match, as closely as possible, the original doors panel and lighting arrangement. Arched doors
can be replaced with rectangular doors if necessary.
City of Oshkosh Traditional tleighbonccod Design Overlay 2 -7 -2014 Page 6 of 23
(i) Storm Doors. Wood storm doors may be
used with exterior doors if the original screen
door is missing. Aluminum, metal, vinyl and
wood composite storm doors may also be
suitable replacements if they match the front
door's size, style and panel and lighting
pattern.
(c) Door Openings. All existing door openings on
a building's front or side facadeslelevations
shall be maintained and not closed. If
necessary, a primary house entrance (door
opening) may be relocated but shall remain
on the exterior facade fronting the street or as
a side entrance to a front porch. A secondary
house entrance may be allowed on a side
yard elevation viewed from the public right -of-
way as long as the original entrance is not
closed or removed.

(E) Existing Buildings: Porches, Decks, Patios and Terraces
(1) Purpose
The purpose of this section is to manage changes to existing porches as well as the design and installation
of new porches, decks, terraces and patios to traditional residential homes located in overlay districts
established by this Section. Porches are significant architectural and character defining features of a
traditional home, and they serve as the formal connection between the home and the street. In almost all
cases, existing porches and their associated elements shall not be removed or altered to such an extent that
they no longer retain their character- defining features nor serve as the formal connection between the house
and the street. New porches shall be constructed in locations where original porches once existed and be
compatible in style and materials to the existing house. Decks, terraces and patios on existing homes are
only permitted when installed on interior side or rear facades and elevations.
(2) Applicability
(a) Existing Porches, Terraces, Decks and Patios — The regulations contained in this section of the Overlay
shall be applicable to changes to existing porches, terraces, decks and patios, such as the
restoration /rehabilitation of an existing porch, terraces, decks and patios or its elements, as well as
common maintenance repairs, such as the repair of steps, rails, balusters, handrails and skirting of
existing traditional residential homes in overlay districts established by this Section. In order to ensure
that changes to porches, terraces, decks and patios are compatible with the surrounding neighborhood,
any changes or addition within these districts after the effective date of the Overlay shall be subject to
the regulations contained in this section.
(b) New Construction - The regulations contained in this Overlay shall be applicable to all new porches,
terraces, decks or patio construction on existing traditional residential homes in overlay districts
established by this Section. To ensure the compatibility of new porches, terraces, decks and patios
developed within the overlay district with that of the surrounding community, any new porch, terrace,
deck or patio within the overlay district after the effective date of the Overlay Code shall be subject to
the regulations contained in this section.
(3) Definitions
(a) Porch. For the purposes of this Overlay, a porch is defined as a permanent structure attached to a
building on the main and/or corner side /secondary elevation with a roof and without permanent walls,
windows or enclosures. A porch's primary purpose is to protect a building's entrance and to offer
shelter for those entering the house from the street. A porch consists of six primary structural and
decorative elements: the porch foundation, steps, porch skirting, porch floor, columns and railings, and
the porch roof. Porches associated with Queen Anne and Victorian styles were usually constructed in
wood; porches associated with Craftsman and later styles were sometimes constructed in masonry.
(b) Deck. For the purpose of this Overlay, a deck is a roofless structure typically attached to a building's
side or rear elevation. A deck's primary purpose is to provide an outside gathering place. Decks are
usually constructed in wood and are often raised off the ground requiring steps. Decks may also be
constructed on the second story of the side or rear elevation encompassing part or the full width of the
elevation.

(c) PatiolTerrace. For the purpose of this Overlay, a patio or terrace is a roofless structure typically
attached to a building's side or rear elevation. A patio /terrace primary purpose is to provide an outside
gathering place. A patio or terrace is usually constructed at grade level with materials such as
concrete, stone or brick pavers, and may incorporate railings or balustrades. Terraces and patios
generally do not have a roof and roof structure as with porches but may incorporate awnings and
awning frames..
(d) Stoop. For the purpose of this Overlay, a stoop is a raised uncovered platform approached by steps to
a building's entrance. A stoop is typically constructed in concrete, stone, wood or brick pavers, and is
smaller in dimensions than a porch, deck or terrace and accommodating only ingress or egress into a
house entrance. A stoop may have railings on one or both sides of the steps.
(4) Porches
(a) Existing Porches. Existing porches on front or side facades /elevations shall be maintained or repaired
and not replaced unless there is evidence of significant deterioration that cannot be feasibly repaired.
Significant deterioration is defined as significant rot in materials, structural deficiencies, and failures in
the foundation, flooring, roof, and overall porch structure.
(i) Foundation. Stone, brick and concretelconcrete block used for porch foundations, whether as a
continuous wall or as separate piers, shall be maintained and repaired as feasible using similar or
compatible materials. Porch foundations constructed in masonry can be repaired through re-
pointing and epoxy consolidation as well as the replacement of individual units of stone, brick and
concrete block depending on the construction of the foundation. Wood foundation piers can be
replaced with concrete or other compatible materials if they are significantly deteriorated. If
foundation footings are not stable, they shall be repaired and stabilized to support the porch
structure. Foundation piers constructed in pressure treated wood shall be primed and painted with
colors that match or are compatible with existing porch colors, after a curing /drying period of no
greater than 18 months.
(ii) Steps. Wood steps are common features of Victorian, Foursquare and other vernacular homes in
traditional neighborhoods. Brick and concrete steps were prevalent in homes from the 1920s
onwards. In general, porch steps shall be repaired and maintained with similar materials
City of Oshkosh Traditional Neighborhood Design Overlay 2 -7 -2014 Page 9 of 23
consistent with the materials found in the porch floor and skirting. Durable wood materials such as
cedar and redwood are preferred, although pressure- treated, wood sawdust or mineral
composite/high density polyurethane plastic (HDPF) can serve as suitable replacement materials.
Steps constructed in pressure treated wood shall be primed and painted with colors that match or
are compatible with existing porch and house colors, after a curing/drying period of no greater than
18 months.
(iii) Skirting. Skirting, is an important decorative
porch element. It also serves to keep animals
out while allowing air to circulate underneath
the porch structure. Skirting original to the
existing house and porch shall be maintained
and repaired whenever feasible. Skirting
material is typically constructed in woods such
as cedar, redwood and cypress and produced
in a lattice form or vertical railings. If skirting
needs to be replaced due to significant
deterioration, it shall be replaced with similar
materials such as wood, pressure treated wood,
wood sawdust or mineral compositelhigh
density polyurethane plastic (HDPE;). Vertical
skirting patterns and pre - fabricated lattice board
panels can be used. Skirting shall not be
secured to the outside face of the deck and if
pressure - treated lumber, shall be painted or
stained to match the porch to which it is being
attached, after a curing/drying period of no
greater than 18 months. Plants, bushes and
flowerbeds can be used to screen areas
beneath a porch but care should be taken to
have bushes and flowers planted on a slope
away from porch foundations to avoid moisture Porch skirting types
infiltration and foundation deterioration. Trees
should not be planted near porch foundations.
(iv) Flooring and Ceiling. All original porch ceiling and flooring materials shall be retained, repaired and
preserved whenever feasible. Individual ceiling and floor boards that are significantly deteriorated
can be replaced with similar materials, usually tongue and grove wood boards for flooring and T' x
6" beadboards for the roof. If an entire porch floor or ceiling has to be replaced, new floor boards
shall match the existing in thickness, profile and texture. Woods such as cedar, redwood and
cypress, and synthetic materials, including pressure - treated, fiber cement, wood sawdust or
mineral composite/high density polyurethane plastic (HDPF) can serve as suitable replacement
materials. Floors and ceilings constructed of pressure- treated wood shall be primed and
painted /stained with colors that match or are compatible with existing porch colors, after a
curing/drying period of no greater than 18 months.
(v) Columns. Porch columns are often constructed in wood, brick, or stucco. All original porch
columns shall be retained, repaired and preserved whenever feasible using epoxy filler or other
materials. Porch columns can be replaced if they show significant deterioration, including visible
signs of rot and structural failure if they cannot support the weight of the porch roof. Replacement
columns shall match the original material wherever feasible, although synthetic materials, such as
City of Oshkosh Traditional Neighborhood Design Overlay 2 -7 -2014 Page 10 of 23
(vi)
pressure- treated wood, fiberglass, wood sawdust or mineral composite /high density polyurethane
plastic (HDPE) are acceptable. Replacements must substantially replicate the existing column's
design style, including its length, width, and profile and detailing. If existing columns are simply
square or round or if all columns are replaced in their entirety (at the same time), replacement
columns shall be at least 6 "x 6" in dimension. Columns constructed of pressure - treated wood
shall be stained, or properly primed and painted with paint colors that match or are compatible to
existing porch colors, after a curing /drying period of no greater than 18 months. If not painted,
pressure- treated wood can be wrapped. Brick or stucco columns should only be repaired in brick
and stucco that are of same color, texture and material strength as the original.
Roof. Porch roofs for most traditional homes were constructed with materials and pitches similar to
the main structure and its overall architectural style.
New porch roofs shall be constructed in that fashion and
be compatible . with the home's architectural style. Handrail
Typically, roofs were constructed with asphalt shingles 1
and a pitch suitable to shed water.
Baluster
(vii) Railings and Balusters. Railing elements typically
include handrails, balusters and posts, which shall be ` I Bottom
retained, repaired and preserved whenever feasible. Rau
Some houses, but rarely, may have solid porch walls
rather than railings, which shall also be maintained if
they are original to the house. Railing elements and
balusters in need of repair and replacement shall use Handrail
similar materials as the original. Synthetics, including
pressure - treated wood, wood sawdust or mineral }
compositeNgh density polyurethane plastic (HDPE) can Baluster
serve as suitable replacement materials. Replacement
materials should substantially replicate the existing I Bottom
railings and balusters in length, width, profile, and Rail
detailing. Railings and Balusters constructed of
pressure - treated wood shall be stained, or properly
primed and painted with paint colors that match or are Railing and baluster types
compatible to existing porch colors, after a
curing/drying period of no greater than 18 months. If not
painted, pressure - treated wood can be wrapped. Spindles or balusters shall not be secured to the
outside face of the porch including but not limited to the rails, rim joist, beam and/or columns
(b) Enclosures. Porches may be enclosed with
glass or screens with no less than 60 percent
transparency (of preexisting open areas) and
as long as the construction of the enclosing
elements are readily reversible. Removable,
seasonal storm windows or screens are
recommended over more permanent window or
screening systems. In enclosed areas that are
not transparent, materials used shall match or
be compatible with the primary facade siding
material, including wood clapboard, vinyl, wood
composite, stucco or other synthetic materials.
Brick or masonry is not acceptable as an
City of Oshkosh Traditional Neighborhood Design overlay 2.7 -2014 Page 11 of 23
enclosure material unless it is consistent and compatible with the house's architectural style.
Enclosed porch: 100 percent transparency recommended
Enclosed porch: 30 percent transparency not recommended
(c) New Porches on Existing Buildings. To the extent that it can be documented, missing original porches
shall be reconstructed to be appropriate and compatible to the style and period of the home in regard to
size, style and detail. Where inadequate documentation exists for the original porch, proposed new
porches shall be typical of those built in the style of the house. New porches shall be constructed in
wood or appropriate composite /synthetic materials such as wood sawdust or mineral composite/high
density polyurethane plastic (HDPE). Pressure treated wood can be used but shall be stained, or
properly primed and painted with paint colors that match or are compatible to existing house colors,
after a curing /drying period of no greater than 18 months. If not painted, pressure - treated wood can be
wrapped. Porches constructed in stucco and brick are acceptable as long such materials are
consistent and compatible with the house's architectural style. An open porch base is prohibited and
must be skirted with wood lattice or other suitable materials as listed in Section 4(a)(iii).
City of Oshkosh Traditional Neighborhood Design Overlay 2 -7 -2014 Page 12 of 23
(d) Stoops: Stoops can be used if no adequate space can be found for a porch structure. Stoops serve as
a means to access a house entrance and shall be constructed to serve this function only. Stoops are
generally designed to fit the size of entrance opening and are usually constructed in concrete, stone,
wood or brick pavers and incorporate railings if the stoop steps rise more than 30 inches. Stoops do not
incorporate other porch structure elements such as posts and roof. An awning may be installed over
the stoop to provide protection from the weather.
(e) Decks. New decks, whether located at ground level or a second story, shall be constructed on a
building's rear fagadelelevation or on a interior side elevation not visible from the street. Decks on front
or side elevations visible from the street will be permitted if it can be shown that they are characteristic
of the house's overall architectural style. Decks are also permitted on corner -side elevations of corner
lots facing a lake, park or other amenable feature. Decks shall be designed to be consistent and
compatible with a house's architectural style and include elements such as posts, railings and
balusters, and be constructed in cedar, cypress, redwood, or appropriate composite materials such as
wood sawdust or mineral composite /high density polyurethane plastic (HDPE), plastic and aluminum.
Decks constructed in pressure - treated lumber, shall be painted or stained, after a curing /drying period
of no greater than 18 months. If not painted, pressure - treated wood can be wrapped.

(f). Patios and - Terraces. New patios and terraces shall be constructed on a building's.rear facade or side
elevation using stone, brick, brick pavers, or concrete. Water permeable pavers are also allowed. For
double - fronted lots, patios and terraces are permitted on one front elevation or side elevation. Patios
are also permitted on comer -side elevations of corner lots facing a lake, park or other amenable
feature. Patios and terraces are typically constructed flush at ground grade level and are not elevated,
although landscape treatments and berming can be employed to elevate the patio or terrace to meet
rear or side entrance grades. Patios and terraces may incorporate railings and balustrades.

(g) Ramps and Special Accessibiliy. Where provisions for accessibility for disabled persons are proposed
to be added to a principal structure's front or side facades/elevations, every effort should be made to
integrate the ramp or other accessibility provisions within the overall design of the principal structure.
Ramps shall be placed on a side or rear elevation in a way that does not remove original building
features and materials. Ramps shall also incorporate elements of the principal structure's building
materials and shall be installed in such a way that its removal will not damage important features and
materials of the principal structure. Ramps constructed in pressure - treated lumber shall be stained or

(1) Purpose
The purpose of this section is to manage siting, placement and design of additions and changes to existing
buildings and structures in traditional neighborhoods located within the Overlay districts established by this
Section. Additions and changes shall be compatible with existing buildings and be harmonious with other
traditional homes and structures within the surrounding blocks and the neighborhood.
(2) Applicability
(a) Additions and Changes -- The regulations contained in this section of the Overlay shall be
applicable to all proposed new additions and changes to existing single and two- family buildings and
structures front or side facades /elevations. In order to ensure that new additions are compatible with
the principal structure or house, any additions within these districts after the effective date of the
Overlay shall be subject to the regulations contained in this section.
(3) Definitions
(a) Addition. An addition is an increase in the footprint size of an existing principal structure or house
through the construction of an additional room or rooms to a front, side or rear elevation. A new
addition can also be a new floor, or portion thereof, to an existing house or a dormer addition as defined
below.
(b) Change. A major change to an existing principal structure is considered any alteration or demolition to
the materials, wall plane and/or architectural features of a front or side fagade or elevation visible from
the street.
(c) Dormer: A dormer is a structural element of a house that protrudes from the plane of a sloping roof
surface. Dormers are used, either in original construction or as later additions, to create usable space in
the roof of a building by adding headroom and usually also by enabling addition of windows.
City of Oshkosh Traditional Neighborhood Design Overlay 2 -7 -2014 Page 15 of 23
(4) General Requirements
Over time, many homes and residences within traditional neighborhoods were expanded to provide
additional living space. It is recognized that additions to existing homes will continue to take place and that
the overall intent of this section is to ensure that new additions and changes are compatible and harmonious
with the original house style and the surrounding neighborhood. Achieving compatibility involves a careful
consideration of the placement of the addition or change to the original house, its overall design, use of
materials and overall scale and massing.
(a) Placement and Orientation. Additions to a principal structure and changes that extend the building
footprint shall be placed on a rear facade, or interior side elevation if rear is not practical, in order to
have a minimal impact on the overall scale and character of the original house. New additions can be
built with or without a setback from the wall plane of the original house. A special exception for an
addition that extends from the front wall plane of the Original house, either at a front or corner -side
elevation, may be granted through the appeals process under certain circumstances; in particular, if
there is a lack of sufficient space in the house's rear yard to place the addition and the addition's overall
design meets all other requirements regarding its design (see following requirements "b" through "g ")
City of Oshkosh Traditional Neighborhood Design Overlay 2.7.2014 Page 16 of 23
(b) Height and Scale. Additions and changes that extend the building height shall not be higher than the
principal structure's dominant or highest roof ridgeline and not overpower the principal structure's
overall scale and massing. The addition's footprint shall not be more than 50 percent of the principal
structure's existing footprint. An exception to the height standard can be made if the addition conforms
and is compatible with the principal structure's overall architectural style and roof shapes and becomes
an integral part of the structure's overall building form and design. Exterior materials of new additions
shall be constructed in the same materials, or combination of materials, as the original building (see
requirement "d" below).
Ar P[% h RWA&a i' —ii
Acceptable roof addition (left), Unacceptable— roof addition extending above the ridgeline (right)
(c) Style and Form. New additions and changes shall reflect or be consistent with the principal structure's
architectural style and roof form. It is not required to replicate the principal structure's architectural style
in exact detail, but the addition's and changes overall roof shape, and door and window opening
patterns and rhythms shall be consistent, compatible and blend with the original house. When a
principal structure incorporates elements of various styles due to earlier additions, the addition shall
employ the style characteristics that are the most dominant.
(d) Materials. New additions and changes may be constructed using modern materials although they shall
be complementary as a way to tie the addition and the original house together. Some material contrast
is allowed but shall be subtle in change with the principal structure's original building materials. For
example, if the original house was sided with wood clapboard, then fiber cement or vinyl siding may be
used for the addition. New additions and changes shall not remove significant character and
architectural- defining features or materials of the front or side facades /elevations of the original house,
such as trim work and corner boards, shingle siding, bargeboard, ornamentation and dormers. Such
features may be removed temporarily but must be reinstalled upon completion of the addition. Material
color shall also match or be complimentary to the principal structures color.

(e)
Window and Door Openings. The relationship of the height and width of windows and doors shall be
consistent to those of the original house
or principal structure. Building addition and change designs that create blank _ �-
walls on any front or side facade are not
permitted. A front or side
fagadelelevation must have 25 percent
of its wall space devoted to window I®

requirement. -� PS% MISuOarehaonNnYAd cnssnsnb-wnwawopzr"
(f) Dormers. New dormers shall be placed
on a principal structure's side or rear
facades and limited to no more than one -half the roof area. A dormer may also be allowed on a front
facade if it is found to be a typical or customary feature of the house's architectural style. Dormers shall
not be constructed to be higher than the roof's dominant ridgeline in order to preserve the original scale
and form of the building from the street level and the public right -of -way.

(g) Foundation. Foundation heights for new additions shall match the same height as the original
structure's foundation. Foundation paneling of "false" stone or brick, and landscape screening with
bushes and vegetation may be used in circumstances to mask the appearance of different foundation
materials.
City of Oshkosh Traditional Neighborhood Design Overlay 2 -7 -2014 Page 18 of 23
(G) New Principal Structure Construction and Infill Development
(1) Purpose
The purpose of this section is to manage placement and design of new principal structure construction on
emptylunimproved or redeveloped lots in traditional neighborhoods. New construction. shall be compatible
and harmonious with other traditional homes and structures within the surrounding blocks and the larger
neighborhood. The overall intent of this section is to ensure that new buildings and homes are compatible
and harmonious with the surrounding neighborhood.
(2) Applicability ,
(a) New Construction /lnfill Development - The regulations contained in this Overlay shall be applicable to
all new construction that is not considered an addition or change to an existing building or structure. To
ensure the compatibility of new development of principal buildings and structures within the overlay
district with that of the surrounding community, any new building or structure developed after the
effective date of the Overlay shall be subject to the regulations contained in the Overlay.
(3) Definitions
(a) New Principal Structure Construction. New principal structure construction is defined as the
construction or building of new single or two- family houses on existing lots or parcels.
(4) General Requirements
A new principal structure located within the Overlay shall be compatible with the size, scale, set back,
massing, material, and character of the buildings which surround it on the same block. Achieving
compatibility must involve a careful consideration of the new building's placement on its lot, its overall
design, use of materials and overall scale and massing in relation to adjacent homes.
(a) Front Setbacks. Front setbacks for new principal structures shall be consistent and align with the
prevailing building setbacks found along the block and surrounding neighborhood. Generally, a
dominant rhythm of spacing is established along a street by uniform lot and building width and new
buildings shall reinforce that rhythm. A distance equal to the average of the existing front yard setbacks
of the two lots principal buildings abutting it is required for new construction. Where there are no
adjacent buildings, the maximum setback is 30 feet, and the minimum setback is 15 feet.

City of Oshkosh Traditional Neighborhood Design Oveday 2 -7 -2014 Page 19 of 23
(b) Side and Rear Yard. Side and rear yard setback reductions for principal structures may be considered
in the determination for special exceptions allowed by the Director of Community Development , or
designee, based on the following circumstances:
(i) Existing setback of primary structures and accessory structures found in the immediate vicinity;
(ii) Setbacks of like structures historically found on the site as determined by historic maps, site plans
Or photographs;
(iii) Shape of lot;
(iv) Alley access or lack thereof;
(v) Proximity of adjoining structures; and
(vi) Preservation of natural or historic features of the site.
Stoops /entrance platforms and porches may encroach into required setbacks by no more than 4 feet.
Encroachments beyond 4 feet will require approval for a setback variance.
(c) Scale and Height. The height of the main roof of a new principal structure shall be compatible by not
contrasting greatly with those of surrounding buildings. For predominantly single and two - family
residential neighborhoods, the height of a new principal structure shall not exceed the height of
surrounding
structures by more
than one story. The
_

and not overpower
adjacent homes in its
height or width.
(d) Orientation. A principal structure and its front elevation and entrance shall be oriented to the primary
street. On comer lots, the principal structure could be oriented to the side street as long as it meets all
setback requirements and includes the front entrance and a minimum of 25 percent of wail space is
devoted to window or door openings. A porch may include an entrance that is side- entered as long as
the entrance is oriented to the building front. Entrances with door glazing and sidelights may be
counted to the 25 percent window opening requirement.
(i) Front entrances shall be identified by a stooplentrance platform (with or without a staircase), or
entrance porch. Full front and wrap - around porches that include the front entrance are also
acceptable. A front entrance can also be accessed by porches, stoops or terraces oriented to the
side of the front elevation.
(e) Style and Form. New principal structure construction shall reflect and/or be consistent with the
architectural styles found along the block and adjacent neighborhood. It is not required to replicate a
certain architectural style in exact detail, but a new building's overall roof shape, and door and window
opening patterns and rhythms shall be consistent with that particular style.
(f) Building Materials. The materials of the principal structure's facades front or side facades /elevations
shall be visually compatible, by not contrasting greatly, with surrounding buildings in the block and
surrounding neighborhood. Modern and latter -day materials can be used as long as they are suitable
City of Oshkosh Traditional Neighborhood Design Overlay 2 -7 -2014 Page 20 of 23
to the style and overall design of the house or principal structure. Some contrast is allowed if such
materials were typically used within a given architectural style's material palette or if a certain part of
house requires certain building materials, such as a sunroom.
(g) Windows and Doors. In new principal structures, the relationship of the height and width of windows
and doors, and the rhythm of solids (walls) to voids (door and window openings) shall be compatible, by
not contrasting greatly, with surrounding buildings in the block or surrounding neighborhood. New
principal structures that create blank walls and elevations are not permitted. A front or side
fagadelelevation shall have at least 25 percent of its wall space devoted to window openings, which
shall follow a width -to- height ratio of 2:3 or 2:1. Doors with glazing and sidelights may be counted
towards the 25 percent requirement. Window openings on the primary street - related front facade of
new construction shall be representative of the window patterns of similarly massed structures and
architectural styles within the surrounding block and neighborhood. In addition, windows on upper floors
on front or side fagadelelevation shall not be taller than windows on the main floor since, typically, first
floors have higher ceilings than upper floors. If no consistent or predominant window patterns can be
found within the adjacent block, this standard will not apply. Permitted window materials are the same
as those specified in Section D(4)(c) in the Existing Buildings: Windows and Doors of this Overlay
Code.
(H) New Accessory Structure Construction and Driveways
(1) Purpose
The purpose of this section is to manage design changes to existing garages and the construction of new
garages and driveways to traditional residential homes in overlay districts established by this Section.
Garages and driveways are considered important architectural and landscape elements that contribute to
the overall appearance of a traditional home and its site. Their preservation, maintenance and design are
also important to ensure visual compatibility and harmony within the larger neighborhood setting.
(2) Applicability
(a) Existing Garages /Carports — The regulations contained in this section of the Overlay shall be applicable
to common changes to existing garages and accessory structures, such as the restorationlrehabilitation
of garage doors and windows and exterior siding and roof materials. In order to ensure that common
changes and repairs to existing garages are compatible with the principal structure or house, any
changes or addition within the Overlay shall be subject to the regulations contained in this section.
(b) New Garages /Carport - The regulations contained in this Overlay shall be applicable to all new garages
and accessory buildings within the Overlay District. To ensure the compatibility of new garages and
accessory structures within these districts with that of the principal structure, any garage or accessory
structure within these districts shall be subject to the regulations contained in this section.
(3) Definitions
(a) Garage. A covered building or structure constructed primarily to park and shelter vehicles. A garage
may be attached or detached from the principal structure.
(b) Carport. A carport is a covered structure that offers limited protection and shelter for vehicles. A
carport may be free - standing or attached to the house or principal structure.

TO: Honorable Mayor and Members of the Common Council
FROM: Darryn Burich
Director of Planning Services
DATE: February 6, 2014
RE: Approve Amendment to Chapter 30 Zoning Ordinance to Create Section 30-
23.1 Traditional Neighborhood Design Overlay District (Plan Commission
recommends approval)
Approve Amendment to Chapter 30 Zoning Ordinance to Create Section 30-
35(M) Design Standards for Single and Two Family Structures (Plan
Commission recommends approval)
BACKGROUND
In 2012, Common Council directed staff to develop a proposal to implement residential
design standards for Oshkosh's traditional neighborhoods for the purpose of helping to
stabilize the quality of housing stock and neighborhoods throughout the community. The City
contracted a planning /design firm (Lakota Group) to develop the design standards proposal
after they visited the community and met with a wide range of stakeholders to solicit input
from which the standards were developed.
A joint workshop was held with the Common Council, Plan Commission, Landmarks
Commission and Sustainability Advisory Board in December 2012 to review the design
standard concepts and provide direction for future action regarding the proposal. In 2013
planning staff formed a stakeholder advisory group representing various community interests
to help staff further develop and refine the Lakota concepts that staff would use in developing
the actual zoning ordinance proposals. With input from that advisory group, staff developed
two ordinance proposals; one for standards that would be applied to one and two family
houses citywide (universal standards) and another set of standards that.could be applied as
an overlay on a case by case basis in the proposed Traditional Neighborhood Design Overlay
District.
Another joint workshop was held in December 2013 to present the two ordinances to' officials
and receive feedback. An open house was held in January 2014 to introduce the two sets of
standards to the public and receive additional feedback. On January 21St, 2014 the Plan
Commission held a public hearing on the ordinance proposal to receive public feedback on
the proposals, On February Ott' the Plan Commission was asked to act on the ordinance
recommendations which Council is now being asked to approve in the current form as
recommended by the Plan Commission.
ANALYSIS
The design standard regulations are proposed to consist of two independent sections in the
Zoning Ordinance that will apply to single and two family homes on a universal /citywide basis
and in separately adopted traditional neighborhood overlay districts. The universal standards
are a relatively simple set of defined basic standards designed to eliminate some of the more
egregious architectural alterations that detract from the character of a house (and resulting
impact -the appearance and quality of life in a neighborhood) such as boarding up windows on
front and side facades; additions of decks and patios to front facades, major changes and
additions, and in -fill construction.
.The traditional neighborhood overlay design code contains specific /detailed model design
standards based on traditional type /style of structures and neighborhood physical and visual
character in regard to compatible design that will be established through the creation of
Traditional Neighborhood Overlay Districts that will be mapped in the future on a
neighborhood by neighborhood basis s, similar to the process followed for all other area wide
zone changes (i.e. neighborhood meetings, public open houses, etc.). The design overlay
district includes regulating common elements that can be viewed from the public right -of -way
with the focus on maintaining original materials but allowing modern replacement materials
that match in size, profile, and detailing to the home's design style. This overlay would
address existing windows, doors, porches, stoops, decks, patios, terraces, additions and
major changes, new construction, in -fill development, new accessory construction and
driveways.
Both sections include an exception process administered by the Director of Community
Development and an appeals process through application to the Plan Commission (versus
the Board of Appeals) to help to expedite the building process for conflicts that may
potentially occur. Since the Plan Commission's meeting on February 4th, staff has made
some minor adjustments to this language to permit more flexibility at the staff level and Plan
Commission for dealing -with unique circumstances that will occur given the age of the
housing stock. In this case "infeasible" was replaced with "unreasonable" and "unnecessary
hardship" with "unreasonable hardship" with the previous language thought to be too limiting
to allow for appeals.
Plan Commission Recommendations
At its February 0 meeting that the Plan Commission was asked to make a recommendation
on the ordinance proposals there was a discussion regarding "outstanding items for Plan
Commission Discussion and Direction" (see attached discussion document) where staff
asked the Plan Commission to make specific recommendations for changes to the proposed
ordinance based on discussions /feedback provided at previous meetings. Staff identified 6
items that either needed direction /clarification or needed to be noted. These items were:
.1. Should porch enclosure language be included in the universal /city -wide design
standards? (Plan Commission recommended against)
2. Should metal doors be an acceptable replacement on a building's front facade? (Plan
Commission recommended to permit metal doors)
3. Should there be a requirement placed in the overlay to require that a specific number
of owners (suggested at 75% by- Realtors Association of Northwest Wisconsin and
the Winnebago Home Builders'Association) be in support of the overlay before an
application can be considered or to the process to repeal? (Plan Commission
recommended against)
4. Multiple sections of both the universal and overlay standards discuss "sides visible
from the street" and applicability of the ordinance to the respective facade. (Plan"
Commission recommended applying the standards to front and side facades
whether visible or not from the street)
5. Multiple sections of both the universal and overlay standards trigger the design
regulations at 50% change to the facade. (Plan Commission recommended
removing the 50% trigger and apply standards to all new alteration activity)
6. Multiple sections of both standards include the word "should" instead of "shall ". (Plan
Commission was in agreement with changing the applicable wording to "shall"
where necessary in the proposals).
The Plan Commission's recommendations have been formatted into the ordinance language
submitted for Council approval It should be noted that Plan Commission recommended
ordinance language is stricter than the advisory stakeholder group's consensus with respect
to items #4 and # 5 above. With respect to #5, it was felt by the Plan Commission that
permitting 50% of a facade to be altered prior to triggering the design regulations would do
little to preserve the architectural integrity of a facade and that it could destroy the fagade
incrementally without reaching the 50% limit. With respect to #4, it was felt that the
determination of what side of a facade was visible from the public street would be too difficult
to administer because almost all side facades are visible from some point along the street
(see staff commentary in document "Amendments made by the Plan Commission
Discussion" for more information).
FISCAL. IMPACT
The full extent of fiscal impact is undetermined given the wide variety of building applications
and methods covered by the proposed regulations. In working with the stakeholder groups
staff has tried to build into the regulations enough flexibility to use alternate building materials
and methods and to allow for exceptions where possible but there will be additional costs for
things such as painting or staining decks and porches constructed in "green treated" lumber
or requiring a minimum level of windows and doors (25 %) for facades fronting a public street.
RECOMMENDATION
The Plan Commission recommended the ordinance proposals at its February 4th, 2014
meeting. If Council would like to make changes to the proposed ordinances for consideration
at the February 25tt' Council meeting, staff is requesting that the Common Council provide
direction at its February 11th meeting so those changes may be incorporated into the final
document for consideration without having to officially amend each individual section of the
proposed ordinance on February 251h. Staff has attached a document titled "Amendments
made by the Plan Commission Discussion" for possible discussion and direction.
Approved,
City Manager
Outstanding Items for Plan Commission Discussion and Direction
I. Potential New Section in Universal/City -Wide Standards: Should porch enclosure Ianguage be
included in the universal/city -wide design standards?
Staff evaluated this suggestion and is hesitant to recommend the porch enclosure language be added to the
universal /city -wide design standards for single and two-family structures as manypost -1950 1nontraditional
style homes do not contain this structural element and staff feels it is a standard more appropriate to
include in the overlay only.
2. Overlay Section D (5)(b): Should metal doors be an acceptable replacement on a buildings front
facade?
This suggested amendment is felt to be reasonable by staff; however, allowing metal doors is not in
character with traditional homes and does have the ability to affect the overall image of the homes front
elevation or facade.
3. Potential New Section in Overlay: Should there be a requirement that a specific number of property
owners (suggested at 75 %) be in support of the Overlay before application can be considered or to start
the process to repeal?
Staff is not in support of this amendment and feels that it could potentially hinder or derail the ability to
place the overlay district on areas that maybe appropriate and desirable but have a sib ificant number of
income producing-properties. Additionally, this practice is a great departure from normal zoning practice
that allows application of zoning districts desio ation or removal through regular legislative processes.
4. Multiple Sections of both Universal/City -Wide
Standards and the Overlay: The definition and
Iimits on "sides visible from the street" needs
adjustment because in most cases all side facades will
be visible,
Staff agrees that the definition and limits on "sides visible
fi°om the street" does need_adjustment as it will overreach
the intent of regulating side elevations and facades
visibility fi -om the ROW /street. Staff suggests refining the
language to better define what is meant by side elevation
visible from the street, such as:
a) Side facades or elevations visible from the street shall
include 15- 20 -25.., linear feet of the side facade or
elevation extending from the frontfavade; or
b} Side facades- or elevations visible from the street shall
include -2216-50%.. of the side facade or elevation
length extending from the front facade.
Staff's preference is to use the straight linear foot method
with a 15joot distance quaker because the percentage
based method could unfairly regulate longer /deeper
homes and may, not result in. a consistent view from the
ROW /street. Additionally, the straight linear foot method is much simpler to convey to hon:eoN�ners and
Contractors as well as admi�zistratively regulate. The 15 foot distance is recommended as the view of a
buildings side facade fi-om the street in traditional neighborhoods is often obscured (if viewed at even a
slight angle) by the proximity of adjacent structures which are not typically setback a great distance from
their neighbors.
5. Multiple Sections of both Universal/City -Wide Standards and the Overlay: Discuss
refining/changing the definition ofmajor change - "50 % change to farrade ". Concern has been
expressed whether the limit is too high in that it would destroy the fagade incrementally without
reaching the 50% limit.
Staff agrees that the 50% change to facade benchmark-for design standard applicability is far too great and
recommends that the term `Major Change" be amended to simply be "Change", with no benchmark or
minimum percent of area of a elevation or facade visible from the street being affected. 777e calculation
example below illustrates how much area andsignificantfeatures can be affectedat even a 30% elevation
or facade area level.,

b. Multiple Sections of both Universal/City -Wide Standards and the Overlay: Replace wording
within codes that currently is "should" to "shall ".
A change in verbiage throughout both the Universal /City -Wide and the Overlay must takeplace as the use
Of the term "shall" is not appropriate ordinance language and is generally not enforceable /defendable
fi-om a legal standpoint.

Plan Commission Amendment
Plan Commission did not support this amendment.
2. Overlay Section D (5)(b): Should metal doors be an acceptable replacement on a buildings

Staff Recommendation
Staff believes this suggested amendment is reasonable, however, allowing metal doors is not in
character with traditional homes and does have the ability to affect the overall irnage.of the homes

Plan Commission Amendment
Plan Commission recommended amending the code to allow metal doors as an acceptable
replacement on a buildings front facade.
3. Potential New Section in Overlay: Should there be a requirement that a specific number of
property owners (suggested at 75 %) be in support of the Overlay before application can be .
considered or to start the process to repeal?
Staff Recommendation
Staff is not in support of this amendment and feels that it could potentially hinder or derail the
ability to place the overlay district on areas that may be appropriate and desirable but have a
significant number of income producing properties. Additionally, this practice is a departure from
normal zoning practice that allows application of zoning district designation or removal through
regular legislative processes.

4. Multiple Sections of both Universal/City -Wide Standards and the Overlay : - The definition
and limits on "sides visible from the street" needs adjustment because in most cases all side
facades will be visible.
Staff Recommendation.
Staff agrees that the definition and limits on "sides visible from the street" does need adjustment as
it will overreach the intent of regulating side elevations and facades visibility from the
ROW /street. Staff suggests refining the language to better define what is meant by side elevation
visible from the street, such as:
a) Side facades or elevations visible from the
street shall include 15- 20 -25. , ; linear feet
of the side facade or elevation extending
from the front facade; or
b) Side facades or elevations visible from the
street shall include 25 %- 50 %... of the side
facade or elevation •Iength extending from
the front facade.
Staffs preference is to use the straight Iinear
foot method with a'15 foot distance qualifier
because the percentage based method could
unfairly regulate longer /dccper homes and
may not result in a consistent view from the
ROW /street. Additionally, the straight linear
foot rhethod is much simpler to convey to
homeowners and contractors as well as
administratively regulate. The 15 foot
distance is recommended as the view of a
buildings side facade from the street in
traditional neighborhoods is often obscured (if
viewed at even a slighf angle) by the proximity
of adjacent structures which are not typically
setback a great distance from their neighbors.
Plan Commission Amendment
Plan Commission recommended amending the code to require that all standards applicable to
"sides visible from the street" be extended to include the full extent of the side facade /elevations,

refining/changing the definition of major change - "50% change to facadc". Concern has been
expressed whether the limit is too high in that it would destroy the facade incrementally
without reaching the 50 %Emit.
Staff Recommendation
Based on public input at workshops, staff agrees that the 50% change to facade benchmark for
design standard appli cability is too great and recommends that the term "Maj or Change" be
amended to simply be "Change ", with no benchmark or minimum percent of area of a elevation or
facade visible from the street being affected. The calculation example below illustrates how much
area and significant features can be affected at a 30% or 50% elevation or facade area level.
Example Facade Area Change Calculation
Front )Facade Area is 25'X 20' 500 sf
Window/Trim "A" Area is 5'X 6' = 30 sf
Window/Trim "B" Area is 5' X 6" =3 0 sf
Window /Trim "C" Area is 5' X 6" = 30 sf
Window/Trim —L)" Area is 5' X 6" = 30 sf
Door /Trim "B" Area is 4'X 8' = 32 sf
Total Facade Change is 152 sf 130.4%
Exam Ie Facade Area Change Calculation
Front Facade Area is 25'X 20'= 500 sf
First Floor Area is 25 'X 10' � 250 sf
Total Facade Change is 250 sf / 50%
Plan Commission Amendment
Plan Commission recommended amending the. code to chang6 the term "Major Change" to
"Change" and remove the 50% change to facade thereby requiring any changes to trigger the
applicability of the various standards.

ITEM: TEXT AMENDMENT TO THE ZONING ORDINANCE ESTABLISHING
DESIGN STANDARDS FOR SINGLE AND TWO- FAMILY STRUCTURES
OR HOMES AND ESTABLISHING A TRADITIONAL NEIGHBORHOOD
DESIGN OVERLAY DISTRICT
Plan Commission meeting of February 4, 2014
GENERAL INFORMATION
Applicant: Department of Community Development
Owner: NIA
Actions Requested:
The City Department of Community Development requests review and approval of two additions to the
City of Oshkosh Zoning Ordinance, as follows:
A) Creating Section 30 -35 (M): Design Standards for Single and Two - Family Structures or Homes;
and
B) Creating Section 30- 23.1(A -J): Traditional Neighborhood Design Overlay.
Applicable Ordinance Provisions:
The Zoning Ordinance, Section 30 -8, establishes the ability of the Common Council, on its own motion, or
on petition after first submitting the proposal to the City Plan Commission, to amend, supplement or change
Zoning District boundaries or regulations of the Zoning Ordinance.
BACKGROUND INFORMATION
In spring of 2012, the Common Council directed staff to develop a proposal for residential design standards
for Oshkosh's traditional neighborhoods. The City contracted the Lakota Group, a planning/urban design
firm out of Chicago, to perform consulting work involving development of residential design and in -fill
standards for the City of Oshkosh. During late summer of 2012, the Lakota Group visited the community
and met with various stakeholders. A set of design standard concepts was developed based on their ,_
observations and input received from stakeholders. A joint workshop with the Common Council, Plan
Commission, Landmarks Commission and SustainabiIity Advisory Board was held in December of 2012 to
review the design standard concepts and gauge support for the direction proposed. Following the
workshop, the Department of Community Development, with assistance from the Winnebago County UW
Extension, formed a Design Standard Review Group who met throughout 2013 and reviewed, discussed and
evaluated the design standard concepts. Feedback from these meetings was used to draft a very general set
of design standards for all single and two- family homes as well as to draft a detailed Overlay District
designed to protect the character and equity of the city's traditional neighborhoods. Another joint workshop
was held in December of 2013 to introduce the two products to officials and receive feedback. Based on a
positive reception at the workshop, a public open house was held on January 15, 2014 to introduce the two
sets of standards to the public and receive feedback. Comments received have been evaluated and
incorporated into the two Zoning Ordinance Sections with several items requiring further discussion.
ANALYSIS
The design standard products are proposed to consist of two independent ordinance sections. The first is a
set of design standards for single and two - family structures or homes that are relatively simple but well
defined basic standards with city-wide application. The second is a traditional neighborhood overlay design
code that contains specific /detailed model design standards based on traditional type /style of structures and
neighborhood physical and visual character in regard to compatible design that will be established through
the creation of Traditional Neighborhood or Planned Development Overlay Districts. Both sections include
an exception process administered by the Director of Community Development and an appeals process
through application to the Plan Commission.
30 -35 (M): Design Standards for Single and Two - Family Structures or Homes
The purpose of the design standards for single and two - family structures is to maintain the basic
architectural quality of residences within the community and to minimize adverse impacts on adjacent
properties and neighborhoods resulting from inappropriate architectural and building construction practices.
It is also the intent of the standards to ensure compatible design between existing and new homes. These
minimal standards are proposed to apply to all single and two- family structures within the City and are
summarized below:
Windows and Doors
• Windows and doors fronting or visible from the street may not be removed by closure or total
filling.
• Windows and doors may not be boarded up for greater than 30 days
Decks and Patios
• Decks and Patios must be located on rear or side facades, with some exception
• Decks visible from the street must include posts, rails and balusters and include requirements for
finish and spindles not to be secured to the outside of the decking components
Major Changes /Additions
• Materials and color must be complementary and tic into the original building, though modern
buildinggmaterials are permitted
• Additions be placed on the rear or side of the original building unless architecturally compatible
and they may not exceed 50% of existing buildings footprint or be higher /taller than existing
dominant roofline
• Fagades facing a public street must not create a blank wall and must have at least 25% of the wall
area devoted to window and/or door openings
In -Fill Construction
• Houses street presence must align with the prevailing front yard setbacks of the adjacent properties
30- 23.1(A -J): Traditional Neighborhood Design Overlay District
The traditional neighborhood design overlay district is intended to foster strong, vibrant traditional
neighborhoods that consist of well- maintained historic homes and well- designed, architecturally compatible
new residential construction. The purpose of the traditional neighborhood design overlay district is to
implement suitable design standards to maintain the unique architectural qualities and features of Oshkosh's
traditional homes; ensure coordinated, compatible design between existing and new homes; minimize
adverse impacts on adjacent properties from buildings that may detract from the character and appearance
of the district as a whole; and create strong neighborhood identities and cohesive design through historic
home feature preservation and well- designed, high quality new construction and site design. The proposed
overlay also seeks to stabilize and increase neighborhood property values and instill a sense of "pride of
place" among residents and property owners in traditional neighborhoods.
The overlay standards are proposed to apply through the
adoption of individual overlay districts to yet undetermined

Item -test amendment Res Design Slandards
The traditional neighborhood design overlay district includes common elements such as regulating facades
or elevations that can be viewed from the public ROW /street; applying to new additions or major changes
as well as new in -fill construction of single and two- family homes located within an overlay district;
focuses on maintaining existing/original materials, when possible but allowing modern replacement
materials that match the originals in size, profile, and detailing and are appropriate to the home's design
style; and requiring pressure treated woods to be stained or painted. Specific components of the traditional
neighborhood design overlay are summarized below:
Existiniz Windows and Doors
• Maintain existing windows unless significantly deteriorated with replacements being required to be
compatible with existing house style and not have more than a 5 to 10% variation in height to width
pattern.
• Maintain existing casings, trim work and sills unless significantly deteriorated with
replacement/new trim work and sills to be compatible to the existing principal structure and match
original in width/profile
• Original door openings on primary (front) elevation not being closed or relocated with the
allowance of a secondary door entrance on side elevation viewed from ROW /street
• Original door and surrounding trim work to be maintained as feasible with replacements matching
design and profile including storm doors matching the front door's size, style, panel and lighting
pattern
Existing Porches, Stoops, Decks, Patios and Terraces
• Original porches, stoops, and patios to be maintained as feasible with replacement parts required to
be similar in profile and detailing
• New or replacement porches must be compatible to house's original porch or established
architecture style
• Regulation specific to foundation piers, steps, skirting, flooring and ceilings, columns, railings and
roofing
• Porch enclosures limited so at least 60 percent of an existing porch is transparent
• Decks and patios limited to a side or rear elevation, with exceptions
• Accessibility ramps encouraged to be placed on side elevation and designed to be integrated into
the house's overall design
Existing Buildings Additions and Major Change
• Applies to any additions that increase the building's footprint size/height or major changes that
affect 50% or more of the front or side elevation that can be viewed from the ROW /street
• Requires additions and major changes to be appropriate to the existing house's design character,
style and form including placement; height and scale; style and form; materials; and window and
door openings
• Limits additions to the side or rear elevations or facades, with exceptions for front elevation or
fa+ ade additions of appropriate design character
• Requires a minimum of 25% percent of a new addition's wall space facing a ROW /street to be
devoted to window /door openings with windows following a proportionate height -width ratio
• Limiting new dormers to be no higher than the existing roof ridgeline and to be placed on side or
rear fagade unless a typical feature of an architectural style
New Principal Structure Construction and Infill Development
• Requires compatible design of new construction in regard to size, form, placement, scale, material
use and setbacks of adjacent homes
• Addresses setback by requiring alignment of in -fill to substantially match adjacent structures and
provides some relief to side and rear setbacks
• Limits heights of in -fill to no greater than one story taller than surrounding structures
• Orients the in -fill structure's front fagade to the ROW /street with required entrances and 25%
window /door openings
Item -text anrendnreni Res Design Standards
• States that the style and form of the in -fill must reflect or be consistent with the architectural styles
found along the block and adjacent neighborhood
• Requires materials of the in -fill structure's facades or elevations that can be viewed from the
ROW /street to be visually compatible, by not contrasting greatly, with surrounding buildings in the
block and surrounding neighborhood
• Prescribe that the relationship of the height and width of windows and doors, and the rhythm of
solids (walls) to voids (door and window openings) be compatible, by not contrasting greatly, with
surrounding buildings in the block or surrounding neighborhood
New Accessory Structure Construction and Driveway
• Require that detached garages should be placed in rear portion of lot or side yard if there is a lack of
sufficient space in the rear
• Requires attached garages to be set back a minimum of 5 feet from principal structure's front
elevation and be compatible with the design of the principal structure or house, including its
materials, color and style
Infill Construction: Driveways
• Allows single, shared, and two -track driveways to be constructed in concrete, asphalt, blacktop,
stone, brick and permeable pavers
As mentioned, the multiple comments staff received from the workshops, open house and general inquiry
have been evaluated with many items directly incorporated into the two Zoning Ordinance Sections.
However several very significant items have surfaced that require further discussion and recommendation
from the Plan Commission and Council. Listed below are changes that have been incorporated into the
ordinance sections as well as items that are outstanding that staff asks for Plan Commission direction.
Changes incorporated_ in the draft ordinances
1. Universal Section 2(a -b): Added an administrative section to the Universal/City-Wide Standards.
2. Universal Section 2(a -b) and Overlay Section (C)(2)(a -b): Adjusted appeal process for both the
Universal/City-Wide Standards and the Overlay to direct appeal requests to the Plan Commission rather
than the Board of Appeals.
3. Universal Section 3(a)(ii): Augmented the Universal/City-Wide Standards to allow a 5 -10% variation
in height to width proportion for windows, if standard sized replacement cannot fit into existing
openings.
4. Universal Section 4(b)(ii): Higher quality woods such as cedar, cypress, redwood, etc. are no Ionger
required to be painted or stained and only pressure treated wood is required to be painted or stained,
after a curing/drying period of no greater than 18 months.
5. Universal Section 4(b)(iii): Redrafted the language that states "Screws and fasteners of railings to
posts shall not be visible from the street" to "Spindles /balusters shall not be secured to the outside face
of the deck including but not limited to the rails, rim joist, beam and/columns ".
6. Universal Section 5(h)(iii): Added a section in the Universal/City-Wide Standards to prohibit multi-
textured or multi - colored patchwork repair or construction if not consistent with the overall design
character of the structure.
7. Universal Section 6(a)(ii): Added condition to setbacks for in -fill construction to determine average
setback if adjoining lots are vacant.
Item -text amendment Res Design Standards
Outstanding Items for Plan Commission Discussion and Direction
1. Potential New Section in Universal/City -Wide Standards: Should porch enclosure language be
included in the universaUcity -wide design standards?
Staff evaluated this suggestion and is hesitant to recommend the porch enclosure language be added to the
universal /city -wide design standards for single and two- family structures as many post -1950 /nontraditional
style homes do not contain this structural element and staff feels it is a standard more appropriate to include
in the overlay only.
2. Overlay Section D (5)(b): Should metal doors bean acceptable replacement on a buildings front
facade?
This suggested amendment is felt to be reasonable by staff; however, allowing metal doors is not in
character with traditional homes and does have the ability to affect the overall image of the homes front
elevation or facade.
I Potential New Section in Overlay: Should there be a requirement that a specific number of property
owners (suggested at 75 %) be in support of the Overlay before application can be considered or to start
the process to repeal?
Staff is not in support of this amendment and feels that it could potentially hinder or derail the ability to
place the overlay district on areas that may be appropriate and desirable but have a significant number of
income producing properties. Additionally, this practice is a great departure from normal zoning practice
that allows application of zoning districts designation or removal through regular legislative processes.
4. Multiple Sections of both Universal/City -Wide
Standards and the Overlay: The definition and
limits on "sides visible from the street" needs
adjustment because in most cases all side facades will
be visible.
Staff agrees that the definition and limits on "sides visible
from the street" does need adjustment as it will overreach
the intent of regulating side elevations and facades
visibility from the ROW /street. Staff suggests refining the
language to better define what is meant by side elevation
visible from the street, such as:
a) Side facades or elevations visible from the street shall
include 15- 20 -25... linear feet of the side facade or
elevation extending from the front facade; or
b) Side facades or elevations visible from the street shall
include 25 %- 50 %... of the side facade or elevation
length extending from the front facade.
Staff's preference is to use the straight linear foot method
with a 15 foot distance qualifier because the percentage
based method could unfairly regulate longer /deeper homes
and may not result in a consistent view from the
ROW /street: Additionally, the straight linear foot method
is much simpler to convey to homeowners and contractors
Item -text amendment Res Design Standards
as well as administratively regulate. The 15 foot distance is recommended as the view of a buildings side
fagade from the street in traditional neighborhoods is often obscured (if viewed at even a slight angle) by
the proximity of adjacent structures which are not typically setback a great distance from their neighbors.
5. Multiple Sections of both Universal/City -Wide Standards and the Overlay: Discuss
refining/changing the definition of major change - "50% change to fagade ". Concern has been
expressed whether the limit is too high in that it would destroy the fagade incrementally without
reaching the 50% limit.
Staff agrees that the 50% change to fagade benchmark for design standard applicability is far too great and
recommends that the term "Major Change" be amended to simply be "Change ", with no benchmark or
minimum percent of area of a elevation or fagade visible from the street being affected. The calculation
example below illustrates how much area and significant features can be affected at even a 30% elevation
or fayade area level.
RE COMMENDATION /CONDITIONS
Example Fagade Area Change Calculation
Front Fagade Area is 25' X 20' = 500 sf
Window /Trim A Area is 5' X 6' = 30 sf
Window/Trim B Area is 5' X 6" = 30 sf
Window/Trim C Area is 5' X 6" � 30 sf
Window/Trim D Area is 5'X 6" = 30 sf
Door/Trim E Area is G' X 8' = 32 sf
Total Fagade Change is 152 sf/ 30A%
Staff recommends that the Plan Commission recommend that Section 30 -35 (M): Design Standards for
Single and Two - Family Structures or Homes and Section 30 -23.1: Traditional Neighborhood Design
Overlay be established within the Zoning Code - Chapter 30, with amendments as determined by the Plan
Commission.
The Plan Commission approved of the Design Standards for Single and Two - Family Structures or Homes
and the Traditional Neighborhood Design Overlay to be established within the Zoning Code - Chapter 30 as
requested with amendments noted. The following is the Plan Commission's discussion on this item.
Mr. Buck presented the item and discussed the procedures involved to develop the proposed design
standards which began in 2012 and continued throughout 2013. The draft ordinance was developed after
workshops, an open house for public comment, and a public hearing at the last Plan Commission meeting.
Mr. Burich stated that this ordinance was not developed by just City staff only but through a cooperative
effort involving an advisory stakeholder group with a goal to reach consensus on as many items as possible.
He further stated that the proposed ordinance is a starting point at this time and provides basic framework to
begin with which can, and likely will, be adjusted as the process is implemented.
Mr. Buck reviewed the two sets of design standards for the single and two- family structures or homes
which will be city -wide and the traditional neighborhood design overlay district which will apply through
the adoption of individual overlay districts to yet undetermined areas. He also discussed the focus of the
design standards ordinance and what it was meant to address. He discussed the traditional neighborhood
Item -fexl anrendment Res Design Standards
design overlay district which contains specific standards based on style of structures and neighborhood
character in older areas and would apply to a block face of properties. He reviewed what is addressed with
this overlay district and discussed some items that need to be changed or addressed by the Plan Commission
prior to the final draft ordinance being completed. He also reviewed changes made by staff since the public
hearing such as clarification of language in some sections of the code. The following six items require
direction from the Plan Commission to determine how the ordinance should be adjusted:
1) Should porch enclosure language be included in the universal /city -wide design standards?
Mr. Buck stated that staff was not recommending to include this language in this ordinance section and to
include it in the overlay district section only.
Ms. Propp and Mr. Nollenberger agreed with this recommendation.
2) Should metal doors be an acceptable replacement on a building's front fagade?
Mr. Buck stated that staff felt this was a reasonable amendment as metal doors can be made to look like real
wood.
Mr. Thoms stated that metal doors are used for both safety and insulation issues and he felt language could
be added to allow metal doors as long as they stay within the character of the home.
Mr. Buck responded that the current draft includes that metal doors are acceptable on only the rear or side
facades.
Mr. Thoms felt that the language could be adjusted to allow metal doors on the front fagade if they
consisted of an acceptable appearance.
Ms. Propp commented that the front door of a home is the most important feature of the structure and was
concerned if it would be the right thing to do to allow metal doors.
Mr. Borsuk stated that slab doors are all the same and we are looking to improve appearance in which case
as long as the door is still appropriate, the material it is comprised of should not matter.
Mr. Cummings commented that as long as it fits the style of the home, the material is not as relevant.
Mr. Thoms questioned if non -wood doors would be required to be painted.
Mr. Buck responded that colors were not addressed in the proposed ordinance just what will be seen from
the public right -of -way.
Mr. )~ojtik questioned if the draft ordinance could be altered to state that the doors would be required to
match the appearance of the house.
Mr. Buck suggested adding language that the door would be required to have a finished coating.
Mr. Borsuk felt that this was getting too technical and from an administrative standpoint, difficult to
enforce.
Mr. Bowen commented that in the traditional overlay district, he felt that the homeowners will make sure
that any renovations would be finished correctly and it would be too difficult to regulate too many small
items.
Item -text ainendinent Res Design Standards
Mr. Hinz stated that we have already heard comments from landlords regarding this ordinance and he felt
they would look for loopholes in it but the ordinance language could be adjusted to address issues at a later
date if the city finds it is being abused.
Mr. Burich agreed and stated that a good foundation is most important and minor details can be addressed
in the fixture if necessary.
3) Should there be a requirement that a specific number of property owners (suggested 75 %) be in
support of the overlay before application can be considered or to start the process to repeal ?.
Mr. Buck stated that staff does not support this amendment as it could potentially hinder the ability to place
the overlay district on some areas that may be appropriate and it would be a great departure from normal.
zoning practices through regular legislative process.
Mr. Burich added that ultimately what an area is zoned is a political decision and he had discussed that
matter with the City Attorney and the percentage method may conflict with state statutes and the proposed
overlay districts could still be initiated by Common Council or staff and what would really be accomplished
through this provision.
Mr. Borsuk questioned how the city would distinguish between owners and residents in an area.
Mr. Buck responded that the property owner on record would possess the only vote that would count.
Mr. Bowen stated that he would not support the percentage method.
Mr. Nollenberger, Ms. Propp, and Mr. Borsuk agreed as they felt it would take all the ability of the
intention of the overlay district out of the code.
4) The definition and limits on "sides visible from the street" needs adjustment because in most
cases all side facades will be visible.
Mr. Buck commented that staff was considering either a method using linear feet of the side fagade
extending from the front fagade or a percentage of depth of the house. Staff's preference would be the
linear feet method as it would be easier to calculate and does not make it more difficult for homes with
more depth. He reviewed examples of both methods and how it would affect the home.
Mr. Nollenberger stated that lie would prefer the linear feet method over the percentage method but 15%
seemed a little short. He felt 20 -25% would be more adequate if this was the method decided upon.
Mr. Thorns questioned the definition of "visible from the street" and how this would be used.
Mr. Buck explained the effects of any alterations equating to 50 percent cumulative change and what
constitutes a major change and to what degree of either side elevations should count as being considered
"visible from the street" or would only the front fagade be considered.
Mr. Thorns commented that if an owner would have the ability to change whatever they desired after the
first 15 feet, more than that could be visible from the street.
Mr. Hinz stated that corner lots would be more difficult as more is visible from the street that interior lots.
Rein -lest amendment Res Design Standards
Ms. Propp felt that 15 feet from the front fagade is not enough as why would the city want homeowners to
have the ability to do inappropriate renovations to.the back third of the home.
Mr. Buck indicated that the goal of the ordinance was to maintain the street presence of the property.
Mr. Thoms commented that he felt all of the sides of the home should be included as visible from the street
and that the ordinance should not be limited to a portion of the side elevation.
Mr. Burich stated that this alteration would involve the entire facade and the intention of the proposed
ordinance was to preserve the general curb appeal of properties.
Mr. Hinz felt that the city needed a starting point for the ordinance and it was a matter of if we should start
out small or heavier handed. Either way, the ordinance could be adjusted to address concerns at a later date.
Mr. Cummings commented that the width of the lot could be a concern with either the linear or percentage
method as it would effect what was visible from the street and he felt that both sides and the front should be
treated the same.
Mr. Burich indicated that the city was attempting to find ways to protect the facades of homes and do so in
a manner that would be administratively enforceable.
Mr. Borsuk stated that some of these details we may not have another chance to alter and he was
comfortable with applying the 25 linear feet method.
Mr. Bowen felt that the easiest thing to regulate in the proposed code was exceptions and appeals to the
code and if both front and side facades were protected within the ordinance, property owners could bring
forward an appeal if they had issues with complying with it. He stated that the entire side elevations should
be addressed by the ordinance.
Mr. Thorns commented that the intent of the proposed ordinance was to preserve the heritage of older
homes and the appeals could be addressed. He felt we could stay within what the ordinance was supposed
to address which is to protect the appearance of the home's fagade.
Mr. Hinz stated that a corner home would have no sides that are not protected under this adjustment to the
ordinance.
Mr. Burich commented that those homeowners would still have the appeals process and some things such
as a wrap around deck in the rear yard may be affected by this alteration.
5) Discuss refining/changing the definition of major change — "50% change to fagade. Concern has
been expressed whether the limit is too high in that it would destroy the fayade incrementally
without reaching the 50% limit.
Mr. Buck stated that staff was attempting to more clearly designate what would be considered the definition
of major change and displayed examples of what would be considered 50% change to the faqade. Staff felt
that the benchmark of 50% was too great and was recommending amending the ordinance to simply be
"change" only and remove the percentage issue from it.
Ms. Propp commented that she felt the diagram says it all and suggested the Commission recommend
proceeding with the "change" only reference and not applying a percentage in the ordinance.
Ilem -text amendment Res Design Standards
Mr. Thoms questioned,if this would constitute any change that would impact the home such as changing a
light fixture.
Mr. Burich responded that the proposed ordinance would apply to building elements only and things such
as a light fixture would not be considered a building element.
Mr. Buck reviewed the architectural features description of the proposed ordinance and reviewed the items
that would qualify as building elements and items such as door knobs, etc. that would not.
Mr. Cummings commented on the Jackson Street neighborhood where homes mostly all have porches
which are pail of the neighborhood style and removal of the porch can change the continuity of the
neighborhood.
6) Multiple sections of the ordinance use the word "should" instead of "shall ".
Mr. Burich informed the Plan Commission that staff was going to change applicable wording in the
proposed ordinances from "should" to "shall" in order to be able to actually enforce the ordinance
provisions. Should is generally found in guidelines or advisory language.
Mr. Buck summarized the Commission's findings on the six items that required additional direction as
follows:
1) Porch enclosure language should not be included in the Universal/City -Wide Standards.
2) Metal doors would be an acceptable replacement on a buildings front facade.
3) A percentage of property owners would not need to support the overlay before application is
considered or repealed.
4) The definition and limits on "sides visible from the street" will include the entire side elevation.
5) The definition of major change was determined to be any change and not have a percentage applied
to it.
6) The word "should" in the ordinance will be changed to "shall" in all areas.
Motion by Nollenbet ger to approve the text amendment to the zoning ordinance establishing design
standards for single and nvo family structures or homes and establishing a h- aditional neighborhood

Plan Commission Feb 4, 2014 Draft
Section 30 -23.1
Draft Traditional Neighborhood Design Overlay
(A) Purpose
Traditional Neighborhood Overlay Districts are established to foster strong, vibrant traditional neighborhoods that
consist of well - maintained historic homes and well- designed, architecturally compatible new residential
construction. Such districts are to be applied in neighborhoods with homes and residences mostly constructed
before 1950.
Therefore, the purpose of the Traditional Neighborhood Overlay District is to implement minimum design
standards intended to maintain the unique architectural qualities and features of Oshkosh's older traditional _
homes; ensure coordinated, compatible design between existing and new homes; minimize adverse impacts on
adjacent properties from buildings that may detract from the character and appearance of the district as a whole;
and, create strong neighborhood identities and cohesive design through historic home preservation and well-
designed, high quality new construction and site design. New residential construction should be compatible in
character with homes in the immediate vicinity, considering scale, style and materials. The Overlay District also
seeks to stabilize and increase neighborhood property values and instill a sense of "pride of place" among
residents and property owners.
(B) Overlay Location
(1) Areas that may be deemed suitable and appropriate for a Traditional Neighborhood Overlay District shall:
(a) Include a grouping of single and/or two- family homes generally constructed prior to 1950 that retain

(C) Administration and Enforcement
The Director of Community Development, or designee, shall serve as the Administrator of this Overlay Code.
The Administrator shall enforce the provisions of this Code. A Traditional Neighborhood Overlay District may be
adopted through a zoning map amendment as a standard overlay district of itself or the overlay district can be
used as a model code as a base for the development of a hybrid /modified design standard overlay through the
adoption of a Planned Development Overlay District.
(1) Adoption Process. Upon receipt of a request to consider application of the Traditional Neighborhood
Overlay District or Planned Development Overlay District to an area of the city, an informal review of the
area of the proposed overlay will be conducted by the Department of Community Development and if
deemed appropriate, a zoning map amendment request and formal review shall be forwarded to the Plan
Commission and Common Council for consideration and action.
The Plan Commission shall review a request for the overlay designation and make a report and
recommendation of denial, approval, or approval with modifications it may deem appropriate to the Common
Council. The Common Council shall act to deny, approve, or approve with modifications any request for the
overlay designation before them for consideration.
(2) Exceptions and Appeals
(a) Exceptions. Exceptions to the building architectural standards set forth in this Section may be granted
by the Director of Community Development, or designee, to permit substitute building materials or
construction methods of comparative quality or design when it can be demonstrated that the provisions
of this Section are infeasible and that the granting of such exception is in keeping with the spirit and
intent of this Section. Decisions rendered by the Director of Community Development or designee may
be appealed to the Plan Commission.
(b) Appeals. The Plan Commission is authorized to grant variances from the strict application of the
standards within the Overlay and an application for an appeal may be made to the Plan Commission
when it is claimed that the intent of the standards in the Overlay have been incorrectly interpreted; do
not apply; or their enforcement cause unnecessary hardship.
(D) Existing Buildings: Windows and Doors
(1) Purpose
The purpose of this section is to manage design changes to the windows and doors of existing traditional
residential homes in overlay districts established by this Section. Along with their primary function of
providing adequate light, ventilation and access to a home's interior, windows and doors contribute
significantly to a house's overall visual proportions, and image and appearance. Original windows and
doors should be maintained wherever appropriate and technically feasible. New windows and doors should
also be visually and functionally compatible with the home's architectural style and other character- defining
features.
(2) Applicability
(a) Existing Buildings -- The regulations contained in this section of the Overlay Code shall be applicable to
major changes to existing buildings that involve 50 percent or more of the front facade wall surface or
any side elevation that may be visible from the public right- of- waylstreet. In order to ensure that major
changes and additions to existing buildings are compatible with the surrounding neighborhood, any
change or addition within these districts after the effective date of the Overlay shall be subject to the
regulations contained in this section.

(3) Definitions
(a) Windows. For the purposes of this overlay fern
code, windows are defined as wall openings
fitted with a frame and glass to admit light and
air into a building's interior. Windows are Han Un
located primarily along a home's surface wall
openings and in dormers, and include features
such as frames, sills, jambs, sashes, muntins
and glazing panes (lights). Other features
may include casing trim and crown moldings, Lower Sash
and decorative wood or stone hoods and
lintels. Window types include double or triple

(4) Windows
(a) Window Casings, Trim Work, and Crown Moldings. Casing, trim work, sills, and crown moldings -
around windows and doorways are significant character - defining and decorative features.for older
traditional homes. They may also provide certain structural functions and protect against water and
weather infiltration around windows. The loss of such features can have considerable impact on a
home's visual appearance and functional operation.
Existing Trim Work. Windows casings, sills, trim work
and crown moldings original to the house and existing
on elevations in view of the public right -of -way should
be repaired and not be removed and replaced unless
there is evidence of missing trim work and/or they are
significantly deteriorated and beyond feasible repair.
Significant deterioration is defined as extensive and
substantial cracks, holes and rot that have
compromised the trim work's or crown molding's
integrity. All casing and trim work shall be maintained
by filling all cracks and holes and repainting when necessary.
Existing trim work and casings should be
maintained whenever feasible
(ii) Replacement Trim Work. For windows viewed from the public right -of -way, replacement trim shall
ideally be made of the same materials as the original trim work. Therefore, w_ ood trim shall be
replaced by new wood trim wherever appropriate. Substitute materials may include fiber- cement,
vinyl, laminated veneer lumber, hardboard, high density polyurethane (HDPE) and other plastic -
wood products. The size (width and height) and profile of the replacement trim shall match the size
and profile of the original trim work where feasible. If no original trim work remains intact, the size
and profile of new trim work shall be compatible with other trim work found on the house or the
house's overall architectural style and visual appearance. if all trim work and casing on the primary
structure are to be replaced, replacements that are consistent in details /type shall be used for all
windows.
(iii) Window Sills. Window sills should only be replaced if there is evidence of significant deterioration.
A wood window sill is considered in deteriorated condition if it has extensive cracks, holes and
decay, and is not sloped away from the building to shed water.. Replacement window sills should
be replaced with similar or other compatible materials and have a drip on the bottom that prevents
water from entering the building under the window assembly. If all window sills on the primary
structure are to be replaced, replacement sills shall be used for all windows, even though not
original to the structure.
(b) Existing Windows. Existing windows viewed from the public right -of -way (front or side -yard elevations)
shall be maintained whenever feasible and not replaced unless there is evidence of significant
deterioration or cannot be feasibly repaired. Significant deterioration is defined as extensive cracks or
material rot in window jambs, rails and muntins. Missing window hardware will not be considered in
assessing a window's condition.
Draft; City of Oshkosh Traditional Neighborhood Design Overlay
Plan Commission Feb 4, 2014 Draft
(c) Window Replacement. A replacement window on an existing building elevation that is viewed from the
public right -of -way shall use the existing window opening and match the original window's height to
width dimensions wherever feasible. A 5 to 10 percent variation in the height -to -width proportion is
allowed if standard sized replacement windows cannot fit into an existing window opening.
(i) Replacement Window Style and Placement
Patterns. A replacement window's style
refers to the windows operation and
framing (i.e., one over one, double - hung),
materials and glazing (lighting) pattern. In
general, a replacement window should be
appropriate and compatible with the style of
the original windows and the house's
overall architectural design features.
Replacement windows should also match
original window placement patterns and
I
arrangements; for example, if the original Double Hung
windows were grouped in 2's or Ts,
replacement windows should maintain this pattern.

(ii) Replacement Window Framing Options. The first window replacement option is a sash -only
replacement where the existing window frame, sill and exterior trim are maintained and in
good condition. This option is preferred before others are considered. If this option is not
feasible due to significant deterioration of the window frame, block frame replacement
windows are recommended for original recessed windows; nail -in frame replacements for
windows flush with the exterior walls. These frame types are more appropriate in maintaining
the original window profiles on elevations viewed from the public right -of -way.
(iii) Replacement Window Materials. Ideally, replacement window materials should match the
original (i.e., wood for wood, metal for metal). Suitable alternative materials include aluminum,
aluminum -clad, fiberglass, steel, vinyl and vinyl -clad windows.
(iv) Replacement Window Operation. For front elevations and side elevations or facades
visible from the street, replacement window operation should match the original (i.e. double -
hung for double -hung; casement for casement, etc.) Changes in window operation types is be
allowed on side and rear elevations that can't be viewed from the public right -of -way.
(v) Window Pane Glazing /Lights. A - --
window's glazing or "divided

(a) Existing Doors and Entrances. Existing doors and entrances are key architectural and visual features
contributing to the character of most building's front elevations and facades. Original doors and any
surrounding casing, trim work, thresholds and other features should be retained and repaired unless
significantly deteriorated. Significant deterioration may be defined as large cracks or rotting materials
and features.
(b) Door Replacements. If a door cannot be repaired and must be replaced, the new door should match
the style of the building and the original door wherever feasible. The original material is preferred for
replacement doors but composite materials are also acceptable. Non -wood doors are acceptable for
rear or side doors. Replacement doors should also match as closely as possible the original door's
panel and lighting arrangement. Arched doors can be replaced with rectangular doors if necessary.

(E) Existing Buildings; Porches, Decks, Patios and Terraces
(1) Purpose
The purpose of this section is to manage changes to existing porches as well as the design and installation
of new porches, decks, terraces and patios to traditional residential homes located in overlay districts
established by this Section. Porches are significant architectural and character defining features of a
traditional home, and they serve as the formal connection between the home and the street. In all cases,
existing porches and their associated elements should not be removed or altered to such an extent that they
no longer retain their character - defining features nor serve as the formal connection between the house and
the street. New porches should be constructed in locations where original porches once existed and be
compatible in style and materials to the existing house. Decks, terraces and patios on existing homes are
only permitted when installed on side or rear facades and elevations.
(2) Applicability
(a) Existing Porches, Terraces, Decks and Patios --The regulations contained in this section of the Overlay
shall be applicable to changes to existing porches, terraces, decks and patios, such as the
resto ratio nlrehabiIitation of an existing porch, terraces, decks and patios or its elements, as well as
common maintenance repairs, such as the repair of steps, rails, balusters, handrails and skirting of
existing traditional residential homes in overlay districts established by this Section. In order to ensure
that changes to porches, terraces, decks and patios are compatible with the surrounding neighborhood,
any changes or addition within these districts after the effective date of the Overlay shall be subject to
the regulations contained in this section.
(b) New Construction - The regulations contained in this Overlay shall be applicable to all new porches,
terraces, decks or patio construction on existing traditional residential homes in overlay districts
established by this Section. To ensure the compatibility of new porches, terraces, decks and patios
developed within the overlay district with that of the surrounding community, any new porch, terrace,
deck or patio within the overlay district after the effective date of the Overlay Code shalt be subject to
the regulations contained in this section.
(3) Definitions
(a) Porch. For the purposes of this Overlay, a porch is defined as a permanent structure attached to a
building on the main and/or corner sidelsecondary elevation with a roof and without permanent walls,
windows or enclosures. A porch's primary purpose is to protect a building's front entrance and to offer
shelter for those entering the house from the street. A porch consists of six primary structural and
decorative elements: the porch foundation, steps, porch skirting, porch floor, columns and railings, and
the porch roof. Porches associated with Queen Anne and Victorian styles were usually constructed in
wood; porches associated with Craftsman and later styles were sometimes constructed in masonry.
(b) Deck. For the purpose of this Overlay, a deck is a roofless structure typically attached to a building's
side or rear elevation. A deck's primary purpose is to provide an outside gathering place. Decks are
usually constructed in wood and are often raised off the ground requiring steps to meet an existing door
or entranceway. Decks may also be constructed on the second story of the side or rear elevation
encompassing part or the full width of the elevation.

(c) Patio/Terrace. For the purpose of this Overlay, a patio or terrace is a roofless structure typically
attached to a building's side or rear elevation. A patio/terrace primary purpose is to provide an outside
gathering place. A patio or terrace is usually constructed at grade level with materials such as
concrete, stone or brick pavers, and may incorporate railings or balustrades. Terraces and patios
generally do not have a roof and roof structure as with traditional porches but may incorporate awnings
and awning frames.
(d) Stoop. For the purpose of this Overlay, a stoop is a raised. uncovered platform approached by steps to
a building's primary or secondary entrance. A stoop is typically constructed in concrete, stone, wood or
brick pavers, and is smaller in dimensions to a porch or terrace and accommodating only ingress or
egress into a house entrance. A stoop may have railings on one or both sides of the steps.
(4) Porches
(a) Existing Porches. Existing porches viewed from the public right -of -way (front or side elevations) shall
be maintained or repaired and not replaced unless there is evidence of significant deterioration that
cannot be feasibly repaired. 'Significant deterioration is defined as significant rot in materials, structural
deficiencies, and failures in the foundation, flooring, roof, and overall porch structure.
(i) Foundation. Stone, brick and concrete/concrete block used for porch foundations, whether as a
continuous wall or as separate piers, should also be maintained and repaired as feasible using
similar or compatible materials. Porch foundations constructed in masonry can be repaired
through re- painting and epoxy consolidation as well as the replacement of individual units of stone,
brick and concrete block depending on the construction of the foundation. Wood foundation piers
can be replaced with concrete or other compatible materials if they are significantly deteriorated. Il
foundation footings are not stable, they should be repaired and stabilized to support the porch
structure. Foundation piers constructed in pressure treated wood should be primed and painted
with colors that match or are compatible with existing porch colors.
(ii) Steps. Wood steps are common features of Victorian, Foursquare and other vernacular homes in
traditional neighborhoods. Brick and concrete steps were prevalent in homes from the 1920s
onwards. In general, porch steps should be repaired and maintained with similar materials
consistent with the materials found in the porch floor and skirting. Durable wood materials such as
Draft: City of Oshkosh Traditional Neighborhood Design Overlay
Plan Commission Feb 4, 2014 Draft
cedar and redwood are preferred, although pressure - treated, wood sawdust or mineral
composite/high density polyurethane plastic (HDPE) can serve as suitable replacement materials.
Steps must be painted regardless of materials, unless constructed of concrete or brick. Paint
colors should match or be compatible with existing porch and house colors.
(iii) Skirting. Skirting is an important decorative
porch element. It also serves to keep animals
out while allowing air to circulate underneath
the porch structure. Skirting original to the OEM=
existing house and porch should be maintained
and repaired whenever feasible. Skirting
material is typically constructed in woods such
as cedar, redwood and cypress and produced
in a lattice form or vertical railings similar to the
ones installed along the porch floor between
columns. If skirting needs to be replaced due to
significant deterioration, it should be replaced
with similar materials such as wood, pressure
treated wood, wood sawdust or mineral
composite/high density polyurethane plastic
(HDPE). Vertical skirting patterns and pre-
fabricated lattice board panels can be used.
Skirting should not be secured to the outside
face of the deck and it should be properly
painted or stained to match the porch to which it
is being attached. Plants, bushes and
11 11 11 11 11 11 11 11 1, 11 11_H_U_U_LLLLLULU_L_U_LL
flowerbeds can be used to screen areas
beneath a porch but care should be taken to
have bushes and flowers planted on a slope Porchskirtinq types
away from porch foundations to avoid moisture
infiltration and foundation deterioration. Trees
should not be planted near porch foundations.
(iv) Flooring and Ceiling. All original porch ceiling and flooring materials should be retained, repaired
and preserved whenever feasible. Individual ceiling and floor boards that are significantly
deteriorated can be replaced with similar materials, usually tongue and grove wood boards for
flooring and 1" x 6" beadboards for the roof. if an entire porch floor or ceiling has to be replaced,
new floor boards should match the existing in thickness, profile and texture. Woods such as cedar,
redwood and cypress, and synthetic materials, including pressure - treated, fiber cement, wood
sawdust or mineral composite/high density polyurethane plastic (HDPE) can serve as suitable
replacement materials. Floors and ceilings constructed of pressure - treated wood should be primed
and painted/stained with colors that match or are compatible with existing porch colors, after a
curing /drying period of no greater than 18 months.
(v) Columns. Porch columns are often constructed in wood, brick, or stucco. All original porch
columns should be retained, repaired and preserved whenever feasible using epoxy filler or other
materials. Porch columns can be replaced if they show significant deterioration, including visible
signs of rot and structural failure if they cannot support the weight of the porch roof. Replacement
columns should match the original material wherever feasible, although synthetic materials, such
as pressure - treated wood, fiberglass, wood sawdust or mineral composite /high density
polyurethane plastic (HDPE) are acceptable. Replacements must substantially replicate the
Draft; City of Oshkosh Traditional Neighborhood Design Overlay 10
Plan Commission Feb 4, 2014 Draft
existing column's design style, including its length, width, and profile and detailing, If existing
columns are simply square or round or if all columns are replaced in their entirety (at the same
time), replacement columns should be at least 6 "x 6" in dimension. Columns constructed of
pressure - treated wood should be stained, or properly primed and painted with paint colors that
match or are compatible to existing porch colors, after a curing /drying period of no greater than 18
months. If not painted, pressure - treated wood can be wrapped if visible from a primary or
secondary street. Brick or stucco columns should only be repaired in brick and stucco that are of
same color, texture and material strength .as the original.
(vi) Roof. Porch roofs for most traditional homes were constructed with materials and pitches similar to
the main structure and its overall architectural style. New porch roofs should be constructed in that
fashion and be compatible with the home's architectural style. Typically, roofs were constructed
with asphalt shingles and a pitch suitable to shed water.
(vii) Railings and Balusters. Railing elements typically
include handrails, balusters and posts, which should be
retained, repaired and preserved whenever feasible.
Some houses, but rarely, may have solid porch walls
rather than railings, which should also be maintained if
they are original to the house. Railing elements and
balusters in need of repair and replacement should use
similar materials as the original. Synthetics, including
pressure4reated wood, wood sawdust or mineral
composite/high density polyurethane plastic (HDPE) can
serve as suitable replacement materials. Replacement
materials should substantially replicate the existing
railings and balusters in length, width, profile, and
detailing. Railings and Balusters constructed of
pressure - treated wood should be stained, or properly
primed and painted with paint colors that match or are
compatible to existing porch colors, after a
curing/drying period of no greater than 18 months. If not
painted, pressure- treated wood can be wrapped if Ralling and baluster types
visible from a primary or secondary street. Spindles or
balusters shall not be secured to the outside face of the
porch including but not limited to the rails, rim joist, beam and/or columns

(b) Enclosures. Porches may be enclosed with glass
or screens with no less than 60 percent
transparency (of preexisting open areas) and as
long as the construction of the enclosing elements
are readily reversible. Removable, seasonal storm
windows or screens are recommended over more
permanent window or screening systems. In
enclosed areas that are not transparent, materials
used should match or be compatible with the
primary fagade siding material, including wood
clapboard, vinyl, wood composite, stucco or other
synthetic materials. Brick or masonry is not
acceptable as an enclosure material.

(c) New Porches on Existing Buildings. To the extent that it can be documented, missing original porches
can be reconstructed to be appropriate and compatible to the style and period of the home in regard to
size, style and detail. Where inadequate documentation exists for the original.porch, proposed new
porches shall be typical of those built in the style of the house. New porches should be constructed in
wood or appropriate composite /synthetic materials such as wood sawdust or mineral composite/high
density polyurethane plastic (HDPE). Pressure treated wood can be used but must be stained, primed
and painted, or wrapped. Porches constructed in stucco and brick are acceptable as long such
materials are consistent and compatible with the house's architectural style. An open porch base is
prohibited and must be skirted with wood lattice or other suitable materials as listed in Section 49a)(iii).
(d) Porch Stoops. Porch stoops can be used if no adequate space can be found for a porch structure.
Stoops serve as a means to access a primary or secondary house entrance and should generally be
constructed to serve this function only. Stoops are generally designed to ft the size of entrance opening
and are usually constructed in concrete, stone, wood or brick pavers and incorporate railings if the
Draft: Ciiy of Oshkosh Traditional Neighborhood Design Overlay 12

stoop steps rise more than 30 inches. Stoops do not incorporate other porch structure elements such
as posts and roof. An awning may be installed over the stoop to provide protection from the weather.
(e) Decks. New decks, whether located at ground level or a second story, should be constructed on a
building's rear faradelelevation or on a side elevation not visible from the street. Decks on front or side
elevations visible from the street will be permitted if it can be shown that they are characteristic of the
house's overall architectural style. Decks are also permitted on corner -side elevations of corner lots
facing a lake, park or other amenable feature. Decks should be designed to be consistent and
compatible with a house's architectural style and include elements such as posts, railings and
balusters, and constructed in cedar, cypress, redwood, or appropriate composite materials such as
wood sawdust or mineral composite/high density polyurethane plastic (»DPE), plastic and aluminum.
Decks constructed in pressure - treated lumber, shall be stained, painted or wrapped, after a
curing /drying period of no greater than 18 months.

(g) Ramps and Special Accessibility. Where provisions for accessibility for disabled persons are proposed
to be added to a portion of a principal structure visible from the public right -of -way, every effort should
be made to integrate the ramp or other accessibility provisions within the overall design of the principal
structure. Ramps should be placed on a side or rear elevation in a way that does not remove original
building features and materials. Ramps should also incorporate elements of the principal structure's
building materials and should be installed in such a way that its removal will not damage important
features and materials of the principal structure. Ramps constructed in pressure - treated lumber, shall
be stained or painted, after a curing /drying period of no greater than 18 months. Installing ramps on the
front facade should be avoided unless it can be demonstrated that there is not inadequate space on
secondary/side or rear elevations to install a ramp or other accessibility provision.

(F) Existing Buildings; Additions and Major Changes
Accessible ramp on side elevation porch
(1) Purpose
The purpose of this section is to manage siting, placement and design of additions and major changes to
existing buildings and structures in traditional neighborhoods located within the Overlay districts established
by this Section. Additions and major changes should be compatible with existing buildings and be
harmonious with other traditional homes and structures within the surrounding blocks and the neighborhood.
(2) Applicability
(a) Additions and Major Changes — The regulations contained in this section of the Overlay shall be
applicable to all proposed new additions and major changes to existing single and two - family buildings
and structures that can be viewed from the public right- of- waylstreet. In order to ensure that new
additions are compatible with the principal structure or house, any additions within these districts after
the effective date of the Overlay shall be subject to the regulations contained in this section.
(i) Side elevations or facades visible from the street shall include XXX of the side facade or
elevation extending from the front fagade
(4) Definitions
(a) Addition. An addition is an increase in the footprint size of an existing principal structure or house
through the construction of an additional room or rooms to a front, side or rear elevation. A new
addition can also be a new floor, or portion thereof, to an existing house or a dormer addition as defined
below.
(b) Major Change. A major change to an existing principal structure is considered any alteration or
demolition equating to 50 percent cumulative change to the materials, wall plane and/or architectural
features of a front or side fagade or elevation visible from the street.
(c) Dormer: A dormer is a structural element of a house that protrudes from the plane of a sloping roof
surface. Dormers are used, either in original construction or as later additions, to create usable space in
the roof of a building by adding headroom and usually also by enabling addition of windows.
(5) General Requirements
Overtime, many homes and residences within traditional neighborhoods were expanded to provide
additional living space. It is recognized that additions to existing homes will continue to take place and that
Draft: City of Oshkosh Tradilional Neighborhood Design Overlay 15
Plan Commission Feb 4, 2014 Draft
the overall intent of this section is to ensure that new additions and major changes are compatible and
harmonious with the original house style and the surrounding neighborhood. Achieving compatibility
involves a careful consideration of the placement of the addition or major change to the original house, its
overall design, use of materials and overall scale and massing.
(a) Placement and Orientation. Additions to a principal structure and major changes that extend the
building footprint should be placed on a rear facade, or interior side elevation if rear is not practical, in
order to have a minimal impact on the overall scale and character of the original house. New additions
can be built with or without a setback from the wall plane of the original house. A special exception for
an addition that extends from the front wall plane of the original house, either at a front or comer -side
elevation, may be granted through the appeals process under certain circumstances; in particular, if
there is a lack of sufficient space in the house's rear yard to place the addition and the addition's overall
design meets all other requirements regarding its design (see following requirements "b" through "g ")

Plan Commission Feb 4, 2014 Draft
(b) Height and Scale. Additions and major changes that extend the building height should not be higher
than the principal structure's dominant or highest roof ridgeline and not overpower the principal
structure's overall scale and massing. The addition's footprint shall not be more than 50 percent of the
principal structure's existing footprint. An exception to the height standard can be made if the addition
conforms and is compatible with the principal structure's overall architectural style and roof shapes and
becomes an integral part of the structure's overall building form and design. Exterior materials of new
additions shall be constructed in the same materials, or combination of materials, as the original
building (see requirement "d" below).

(c) Style and Form. New additions and major changes should reflect or be consistent with the principal
structure's architectural style and roof form. It is not required to replicate the principal structure's
architectural style in exact detail, but the addition's and major changes overall roof shape, and door and
window opening patterns and rhythms should be consistent, compatible and blend with the original
house. When a principal structure incorporates elements of various styles due to earlier additions, the
addition should employ the style characteristics that are the most dominant.
(d) Materials. New additions and major changes may be constructed using modem materials although
they must be complementary as a way to tie the addition and the original house together. Some
material contrast is allowed but should be subtle in change with the principal structure's original building
materials. For example, if the original house was sided with wood clapboard, then fiber cement or vinyl
siding may be used for the addition. New additions and major changes shall not remove significant
character and architectural- defining features or materials of the original house that are visible from the
street, such as trim work and corner boards, shingle siding, bargeboard, ornamentation and dormers.
Such features may be removed temporarily but must be reinstalled upon completion of the addition.
Material color should also match or be complimentary to the principal structures color.

may be counted towards the 25 percent
requirement.
(f) Dormers. New dormers should be placed on a principal structure's side or rear facades and limited to
no more than one -half the roof area that is visible from the primary or secondary/side street. A dormer
may also be allowed on a front fagade if it is found to be a typical or customary feature of the house's
architectural style. Dormers should not be constructed to be higher than the root's dominant ridgeline in
order to preserve the original scale and form of the building from the street level and the public right -of-
way.

(g) Foundation. Foundation heights for new additions should match the same height as the original
structure's foundation. Foundation paneling of 'false" stone or brick, and landscape screening with
bushes and vegetation may be used in circumstances to mask the appearance of different foundation
materials.

(G) New Principal Structure Construction and Infill Development
(1) Purpose
The purpose of this section is to manage placement and design of new principal structure construction on
emptylunimproved or redeveloped lots in traditional neighborhoods. New construction should be compatible
and harmonious with other traditional homes and structures within the surrounding blocks and the larger
neighborhood. The overall intent of this section is to ensure that new buildings and homes are compatible
and harmonious with the surrounding neighborhood. ,
(2) Applicability
(a) New Constructionllnfill Development - The regulations contained in this Overlay shall be applicable to
all new construction that is not considered an addition or major change to an existing building or
structure. To ensure the compatibility of new development of principal buildings and structures within
the overlay district with that of the surrounding community, any new building or structure developed
after the effective date of the Overlay shall be subject to the regulations contained in the Overlay.
(3). Definitions
(a) New Principal Structure Construction. New principal structure construction is defined as the
construction or building of new single or two- family houses on existing lots or parcels.
(4) General Requirements
A new principal structure located within the Overlay should be compatible with the size, scale, set back,
massing, material, and character of the buildings which surround it on the same block. Achieving
compatibility must involve a careful consideration of the new building's placement on its lot, its overall
design, use of materials and overall scale and massing in relation to adjacent homes.
(a) Front Setbacks. Front setbacks for new principal structures must be consistent and align with the
prevailing building setbacks found along the block and surrounding neighborhood. Generally, a
dominant rhythm of spacing is established along a street by uniform lot and building width and new
buildings should reinforce that rhythm. A distance equal to the average of the existing front yard
setbacks of the two lots principal buildings abutting it is required for new construction. Where there
are no adjacent buildings, the maximum setback is 30 feet, and the minimum setback is 15 feet.

(b) Side and Rear Yard. Side and rear yard setback reductions for principal structures may be considered
in the determination for special exceptions allowed by the Director of Community Development, or
designee, based on the following circumstances:
(i) Existing setback of primary structures and accessory structures found in the immediate vicinity;
(ii) Setbacks of like structures historically found on the site as determined by historic maps, site plans
or photographs;
(iii) Shape of lot;
(iv) Alley access or lack thereof;
(v) Proximity of adjoining structures; and
(vi) Preservation of natural or historic features of the site.
Stoops /entrance platforms and porches may encroach into required setbacks by no more than 4 feet.
Encroachments beyond 4 feet will require approval for a setback variance.
(c) Scale and Height. The height of the main roof of a new principal structure shall be compatible by not
contrasting greatly with those of surrounding buildings. For predominantly single and two- family
residential neighborhoods, the height of a new principal structure shall not exceed the height of
surrounding
structures by more
than one story. The
overall scale and
height of the principal ;
structure should
reference existing
homes in the
surrounding block - _ x'
and not overpower
adjacent homes in its
height or width.
(d) Orientation. A principal structure and its front elevation and entrance should be oriented to the primary
street. On corner lots, the principal structure could be oriented to the side street as long as it meets all
setback requirements and includes the front entrance and a minimum of 25 percent of wall space is
devoted to window or door openings. A porch may include an entrance that is side - entered as long as
the entrance is oriented to the building front. entrances with door glazing and sidelights may be
counted to the 25 percent window opening requirement.
(i) Front entrances should be identified by a stoop /entrance platform (with or without a staircase), or
entrance porch. Full front and wrap - around porches that include the front entrance are also
acceptable. A front entrance can also be accessed by porches, stoops or terraces oriented to side
of the front elevation.
(e) Style and Form. New principal structure construction should reflect and/or be consistent with the
architectural styles found along the block and adjacent neighborhood. It is not required to replicate a
certain architectural style in exact detail, but a new building's overall roof shape, and door and window
opening patterns and rhythms should be consistent with that particular style.
(f) Building Materials. The materials of the principal structure's facades or elevations that can be viewed
from primary and secondarylside streets shall be visually compatible, by not contrasting greatly, with
surrounding buildings in the block and surrounding neighborhood. Modern and latter -day materials can
Draft: City of Oshkosh Traditional Neighborhood Dosign overlay 20
Plan Commission Feb 4, 2014 Draft
be used as long as they are suitable to the style and overall design of the house or principal structure.
Some contrast is allowed if such materials were typically used within a given architectural style's
material palette or if a certain part of house requires certain building materials, such as a sunroom.
(g) Windows and Doors. In new principal structures, the relationship of the height and width of windows
and doors, and the rhythm of solids (walls) to voids (door and window openings) shall be compatible, by
not contrasting greatly, with surrounding buildings in the block or surrounding neighborhood. New
principal structures that create blank walls and elevations that can be viewed from the public right-of-
way/street, including a primary or secondary/side street, are not permitted. A front or side elevation(s)
facing the public right -of -way must have at least 25 percent of its wall space devoted to window
openings, which should follow a width -to- height ratio of 2:3 or 2:1. Doors with glazing and sidelights
may be counted towards the 25 percent requirement. Window openings on the primary street - related
front facade of new construction should be representative of the window patterns of similarly massed
structures and architectural styles within the surrounding block and neighborhood. In addition, windows
on upper floors on primary and secondary facades viewed from the right -of -way should not be taller
than windows on the main floor since, typically, first floors have higher ceilings than upper floors. If no
consistent or predominant window patterns can be found within the adjacent block, this standard will not
apply. Permitted window materials are the same as those specified in Section D(4)(c) in the Existing
Buildings: Windows and Doors of this Overlay Code.
(H) New Accessory Structure Construction and Driveways.
(1) Purpose
The purpose of this section is to manage design changes to existing garages and the construction of new
garages and driveways to traditional residential homes in overlay districts established by this Section.
Garages and driveways are considered important architectural and landscape elements that contribute to
the overall appearance of a traditional home and its site. Their preservation, maintenance and design are
also important to ensure visual compatibility and harmony within the larger neighborhood setting.
(2) Applicability
(a) Existing Garages/Carports. — The regulations contained in this section of the Overlay shall be applicable
to common changes to existing garages and accessory structures, such as the restoration /rehabilitation
of garage doors and windows and exterior siding and roof materials. In order to ensure that common
changes and repairs to existing garages are compatible with the principal structure or house, any
changes or addition within the Overlay shall be subject to the regulations contained in this section.
(b) New GarageslCarport - The regulations contained in this Overlay shall be applicable to all new garages
and accessory buildings within the Overlay District. To ensure the compatibility of new garages and
accessory structures within these districts with that of the principal structure, any garage or accessory
structure within these districts shall be subject to the regulations contained in this section.
(3) Definitions
(a) Garaqe. A covered building or structure constructed primarily to park and shelter vehicles. A garage
may be attached or detached from the principal structure.

from the property line to a garage, carport or parking area(s).
(1) GarageslCarports
(1) New garages/carports for existing principal structures shall be constructed as a detached or attached
structure located in the rear portion of the lot.
(a) Where the rear lot area cannot accommodate a detached garage or attached garage/carport, an
attached garage or carport located on the side of the principal structure may be considered if:
(i) Designed as an integral element of the principal structure
(il) Recessed a minimum of 5 feet behind the principal structure's front facade
(iii) The roof line(s) of the principal structure is maintained
(b) Attached garages/carports facing the street should be designed and detailed to match or
compliment the roof form and scale employed on the principal structure. Attached garages/carports
may also be connected to the house through a breezeway.
(2) Design. New garages/carports that are visible from the street shall be architecturally compatible and
complimentary with the design of the principal structure or house, including its color and style. Variation
in regard to roof shape and slope and the use of materials is allowed.

MEMORANDUM
TO: Honorable Mayor and Members of the Common Council
FROM: Oshkosh Landmarks Commission
DATE: February 13, 2014
RE: Recommendation on Amendment to Chapter 30 Zoning Ordinance to Create
Section 30 -23.1 Traditional Neighborhood Design Overlay District and
Amendment to Chapter 30 Zoning Ordinance to Create Section 30 -35(M) Design
Standards for Single and Two Family Structures
At its February 12, 2014 meeting, the Landmarks Commission was asked to review and make a
recommendation on the two single and two - family ordinance amendment proposals; one for
standards that would be applied to one and two family houses city -wide (universal /city -wide
standards) and another set of standards that could be applied as an overlay on a case by case basis
in the proposed Traditional Neighborhood Design Overlay District.
The Landmarks Commission unanimously concurs with the Plan Commission's recommendation
to approve the text amendments with changes including the removal of the 50% facade alteration
trigger for standard applicability as well as the determination that the entire side
facades /elevations should be included in reviews rather than simply a portion of them. The
Commission felt that the proposed amendments are not as strong as what they could be,
especially for designated Historic Districts, but that they are a good start to direct and encourage
appropriate changes and/or alterations to traditional homes and neighborhoods within the
community and especially within future designated/adopted areas.
The Landmarks Commission would like to ask the Council to consider relocating the
exception/appeals sections to the back or end of each code section rather than the beginning to
place less emphasis on them. Additionally, the Commission would like to register a statement
that design standards be considered in future code revisions for institutional, commercial and
multiple family structure rehabilitation or in -fill projects, when located within our traditional or
historic neighborhoods.
