' Central Ames Compatibility Standards
INTRODUCTION The Central Ames Compatibility Standards have been created
' as part of the efforts to protect and preserve the residential area
located north of the Downtown Commercial District in Ames,
Iowa. This area, defined as the Single Family Conservation
' Overlay District (SFCOD), will have multiple layers of
regulations for that purpose. The first layer will be the existing
base zoning regulations. The SFCOD is currently zoned R-3
' (Medium-Density Residential) and R-4 (High-Density
Residential). A portion of the SFCOD is also subject to the
' Historic Preservation regulations.
Many residents of the SFCOD supported a request for the
rezoning of the District to R-2 (Low-Density Residential). The
' SFCOD was originally developed as single-family, but was
rezoned to multi-family in the 1940's. Over the years single
' family homes have been converted to multiple family dwellings
and numerous multi-family structures have been developed
inside the district. The request for rezoning to R-2 was denied
' in part so as to prevent the existing multifamily uses from
becoming nonconforming.

This house is located inside the Old Town Historic District. Note the front porch,
vertical windows,lack of drive way,and steep sloping roof pitch.
The Land Use Policy Plan (LUPP), which was adopted in draft
' in June of 1996, designated the SFCOD area as medium
density residential. The LUPP also recommended that a
"Conservation District" be created and that "compatibility
standards be established to guide the design integration of new
Page 1
' Central Ames Compatibility Standards
development with existing development." The LUPP also
stated that `compatibility standards should address, but not
necessarily be limited to, scale, height, rhythm and style." This
recommendation can be found on pages 35-37 in the Urban
' Core Policy Options section of the LUPP.
As recommended, a Single Family Conservation Overlay
District and Compatibility Standards are being established. The
SFCOD will be the second layer of regulations and will cover
the same boundaries as the compatibility standards. The
' SFCOD will place limits on the maximum number of multi-family
dwelling units as a percentage of total dwelling units allowed to
occur in the district and will establish criteria concerning the
permissibility of new multifamily units.
The compatibility standards, appropriately titled the Central
Ames Compatibility Standards, will be included as one
component of the previously stated will cover the same area as
' the SFCOD. The Central Ames Compatibility Standards will
address the issues of scale, height; rhythm and style by
establishing parking, appearance, width, and height
' requirements for any new construction inside the district.
To facilitate the creation of the Compatibility Standards a seven
member citizen task force was created. This task force was
made up of residents of the district who represented the
interests of single family home owners, multi-family developers,
' and a general citizen perspective. The task force was helpful
in determining the essential qualities and characteristics of the
district and in the creation of standards which will be functional
' with various types of development.
The third layer is the historic preservation regulations for the
' Old Town Historic District, The Old Town Historic District
includes a portion of the SFCOD. Historic preservation
regulations apply design guidelines to alterations, new
construction and demolition in the historic district.
Upon designation of the area as a SFCOD, all new construction
and additions to existing structures would be subject to the
compatibility standards. In cases where the compatibility
standards would conflict with historic preservation regulations
' the most restrictive requirements would apply.

LOCATION The Compatibility Standards will apply to all properties located
inside the Overlay District which is described as the area
bounded by: Sixth street between Grand and Clark Avenue;
Clark Avenue between Sixth and Seventh Street; Seventh
' Street between Clark and Duff Avenue; Duff Avenue between
Seventh and Tenth Street; Tenth Street between Duff and
Kellogg Avenue; Kellogg Avenue between Tenth and Eleventh
' Street, Eleventh Avenue between Kellogg and Grand Avenue,
and Grand Avenue between Eleventh and Sixth Street. Also
included in the district are nine lots which are located north of
' Ninth Street and east of Duff Avenue.
The map on the following page shows the boundary line of the
SFCOD and the location of the Old Town Historic District.

FOR CENTRAL AMES NEIGHBORHOOD

' Central Ames Compatibility Standards
CHARACTERISTICS One of the notable characteristics of this district is the sense
OF THE DISTRICT of place created by the streetscape. The streetscape is that
general area between facing structures which includes the
street, the street right-of-way and the front yards on either side
of the street. The character created here is one of quiet, shady
streets lined with houses tall enough and close enough together
to frame the street as a visual space. In this neighborhood, the
residential street is the defining open space of the
neighborhood, and the focus of the first level of civic life. Here
neighborly interactions across the street and next door are
encouraged by the intimate scale of the setting.
' The street in this neighborhood functions as a social channel in
addition to providing access. It is common for people to use
their front porches in nice weather, and to walk, bike and skate
' on the sidewalks. It would not be uncommon for youths to
gather and play games in the streetscape. This is possible
because the scale of the street corridor is small, and traffic
' volumes are relatively low.
The visual character, of this district stems from the interplay of
a number of design features: roadway width; setbacks; side
yards; and the "layering" of front yards with plantings, which
help to define the space from roadway to house. The layers of
' the street corridor include a typical pavement width of 24 to 30
feet; a 10 to 15 foot right-of-way tree strip; a 4 foot sidewalk,
and front yards averaging between 20 and 25 feet. The front
facades of houses visually contain this corridor, although the
feeling of visual enclosure is enhanced by the layer of mature
street trees. The boundary between the visually "public" street
' corridor and the private, interior world of the house is commonly
softened with a front porch and other layering devices.
' The visual continuity of the corridor depends, to some extent,
on side yard dimensions. In this district, the total side yard
average between buildings is 27 feet. This sets up the rhythm
' of the neighborhood. A large variety of architectural styles exist
throughout the district, however, it is the visually-contained
street corridor which is the essential component which must be
maintained. It is this which constitutes the basic ordering
device of the neighborhood, and provides its defining imagery.
Neighborhood streets in this district facilitate and control traffic
circulation, function as social channels, and also provide
parking. However, if on street parking were required to
accommodate all of the parking needs for the residents, both
Page 5
1
1 Central Ames Compatibility Standards
1 sides of the streets would be lined with cars, severely impeding
circulation. What is unique about this district is that the majority
of the homes do not have driveways which access from the
street. The system is kept functioning by widespread use of the
alleys for access to parking and garages. Fewer driveways
allows more curb space to be utilized for parking and helps to
1 encourage the pedestrian oriented atmosphere. For this
reason on-street parking, even though limited to one side of the
street, is not congested.
1 The atmosphere created by this parking arrangement does not
lend itself to larger, visible parking lots which are typical of
1 commercial uses or multi-family complexes. In order to
preserve the streetscape as a visual entity, large-scale parking
lots must be located, as is the trend, to the rear of the lots
1 where they are hidden from view:
An unwritten code might have been sufficient in a period when
1 shared architectural tastes, tradition or limited technology
tended to produce a harmonious ensemble of structures.
Today, however, regulations will need to be adopted and
1 enforced which promote a pattern of development which
compliments the specific character of the existing
neighborhood. It is for this reason that the following
1 Compatibility Standards have been produced.

CENTRAL AMES COMPATIBILITY STANDARDS
' PARKING Parking requirements will be used to encourage the continued
use of the alleys for vehicular access to properties. The
following parking requirements shall be used to maintain the
' pattern of driveways and garages being located in the rear yard
and to preserve the existing character of the streetscape.
' Rear Yard Parking All new driveways which are located in the front yard shall be of
a width no greater than twelve (12) feet. This width requirement
shall apply to only that area between the street and the primary
' facade of the structure. The front yard shall always be the
narrowest portion of a lot which faces a street.
2 z
•5
The garage in this photo is facing the alley and is an example of rear yard parking.
Detached garages which open to an alley must be located
' either eight (8) feet from the property line adjacent to the alley
or a minimum of twenty (20) feet from the property line adjacent
to the alley. The eight foot setback is to allow for 43 feet of
' turning radius into the garage, but does not allow enough of a
setback to be used for head-in parking, No setback between
eight feet and twenty feet shall be allowed for the purpose of
' discouraging head-in parking which would potentially block the
alley. The allowance of an eight foot setback for an alley facing
garage is one of two exceptions where the compatibility
standards are less restrictive than the base zoning regulations.
Page 7
' Central Ames Compatibility Standards
A parking lot shall be defined as any portion of a property,
paved or unpaved, which is specifically allocated to the parking
of vehicles, Driveways shall not be considered a parking lot.
' No parking lot shall be located in the front yard or side yard of
any lot inside the district. Therefore, only rear yard parking lots
' are allowed. This requirement is necessary to establish the
structure as the dominate feature of the property, rather than
the parking lot.
' Alleys/Garages For properties which have access to an alley, any new driveway
shall be constructed in the rear yard with access only from the
' alley, Driveways which are currently located in the front yard
and are accessed directly from the street shall only be
permitted for lots which do not have access to an alley.
' Existing front yard driveways may be maintained or replaced,
but by no means shall any existing driveway be widened to
more than twelve (12) feet in width.
' Driveways leading from an alley which provide access to a
parking lot may be constructed at a width of sixteen (16) feet,
' rather than 24 feet, as is typically required. This is the second
example where the compatibility standards are less restrictive
than the base zoning regulations.
' All garages, attached or detached, shall be setback a minimum
distance of eighteen (18) feet behind the primary facade of the
' structure.
APPEARANCE The Compatibility Standards differ from the Historic
STANDARDS Preservation District requirements in that it does not have
specific architectural detail requirements. However, some
' appearance standards are necessary in order to maintain the
character and integrity of the neighborhood. The following
requirements represent reoccurring patterns which have been
determined to be vital to maintaining the character of the
district.
Tree Replacement One of the defining characteristics of the Overlay District is the
abundance of over story trees located in the street right-of-way.
For that reason, every existing tree which is removed from the
' street right-of-way must be replaced in the street right-of-way as
close to the original location as is possible. The replacement
tree must be an over story tree from the City's list of
recommended trees for planting in the public right-of-way.

' Central Ames Compatibility Standards
Solid/ Void Ratios It is the solid /void relationship created by openings in the walls
of buildings which gives each structure its own distinctive
quality. The open character of buildings which have windows
' and doors facing the street help to create that area described
yr' •..k?7' 0' .'�': Y,�.- ��

' Over story trees located in the street right-of-way "frame" the street and are an
essential quality of the street scape.
' as the streetscape. It is the intent of the following solid /void
ratio requirements to promote architectural character and
preserve the nature of the streetscape. This shall be
accomplished by requiring a percentage of street facing
facades to be voids, thus eliminating the "blank wall" effect.
' A solid void ratio shall be required for the primary facade,
including any recessed facades which face the front yard, and
the secondary facade. Windows and door openings shall be
defined as the void and the total surface area of the wall,
including the void areas, shall be defined as the solid. The void
requirement for the primary facade of new buildings shall be a
minimum of 15% and a maximum of 80%.
' The area defined as solid shall be calculated by multiplying the
width of the front facing facade(s) with the height, measured
between the foundation and roof line. A gable area shall not be
' included in this measurement to avoid the encouragement of
facing roof planes toward the streetscape.
' The void area shall be calculated by adding the area of all
window and door openings. These shall be measured around
the perimeter of the frame in determining area. Note that any
front facing window or door shall be included in the void area,
Page 9
Central Ames Compatibility Standards
regardless of its location. For example, a window located in a
' dormer facing the street would be included in the void area
even though it is not located inside the area from which the
solid was calculated.
t
•,z
r -
This picture indicates those areas which are considered voids and that area
which is considered the solid. Note that this house has a solid to void ratio of
only 17%. It is the existence of the porch and dormer which break up the
facade and provide character to this home,
Roof Pitch Roof pitch has a major impact on the perceived scale of a
' structure as well as the overall appearance. In general, the
majority of the structures in the district have distinct vertical
emphasis and are capped with a roof of substantial pitch.
A roof pitch minimum of 6:12 rise to run shall be required.
However, mansard and mansard style roofs will be permitted.
Building additions, with the exception of porches and stoops,
shall be required to have similar roof pitches as the existing
structure to which they are being added. The roof pitch
' requirement shall not apply porches or stoops.
Dormers A dormer requirement shall be used to create visual character,
' break up large street facing expanses of roof, and encourage
street facing gables. In cases where the primary facade does
not have a gable facing the street, a minimum of one dormer
shall be required for every fifteen (15) feet of street facing roof
width, after the first twenty (20) feet. Therefore, a twenty foot
wide roof plane with no gable is not required to have a dormer,
' but a roof plane wider than twenty feet, with no gable, must
Page 10
Central Ames Compatibility Standards
have at least one dormer for every fifteen feet, or fraction of
fifteen feet, of width beyond the original twenty feet.
' For example: a 20 foot wide roof requires no dormer, a roof
width between 20 feet and 35 feet requires at least one dormer,
a roof width between 35 feet and 50 feet requires at least two
' dormers, and so on in increments of fifteen feet.

F
This photo illustrates the effective use of a dormer to break up a street facing
roof expanse. Notice also the use of vertical oriented windows and a stoop on
the primary facade.
' Window Orientation Windows used in new construction will need to have a vertical
emphasis to correspond with the predominant pattern in the
surrounding neighborhood. Orientation will be determined by
the framing of the window. For example, a series of windows
may be placed in a horizontal row, provided that each individual
window has the required vertical orientation.
A minimum width to height ratio of 2:3 shall be required.
Allowed windows will have a width no greater than two thirds
' their height. This requirement shall only apply to the primary
facade, front facing recessed facades, and the secondary
facade. In addition, an exception will be made for decorative
' windows, gable windows, or a single large window where the
interior floor plan contains a space where such a window type
' would be expected.
Entrances In keeping with the character of the district, an entrance shall
be required which opens to the streetscape on primary facade
' of any new structure. This entrance must face the street and be
Page 11
' Central Ames Compatibility Standards
accessible by means of a sidewalk. No more than one
entrance shall be placed on any primary or recessed facade.
Porches/Stoops Front porches represent a very frequent pattern of design and
' shall be required on the primary facade of any new building
inside the district.
' In order to maintain proper scale, porches and stoops will be
defined as separate entities and will have different
requirements.
Where a porch is constructed, the porch must have a depth of
not less than six (6) feet, and must extend a minimum of fifty
(50%) percent of the width of the facade to which it is attached.
A stoop will be required to be of a width not greater than thirty
(30%) percent of the width of the facade to which it is attached
and must be of a depth not less than four (4) feet.
a
' This picture illustrates the use of a bracket supported stoop and the use of
foundation plantings.
' Porches and stoops shall not be enclosed by walls, windows,
or solid doors. The roof of a stoop wich is supported by
brackets must project from the building theminimum depth of
four (4) feet, Porches and stoops shall not exceed ten (10) feet
in height, This distance shall be measured from the floor of the
first story to the roof line of said porch or stoop.
Foundation The typical construction method used on the majority of the
structures located inside the district consists of raised first floors
' with full foundations. Newer buildings are commonly
Page 12
Central Ames Compatibility Standards
' constructed slab on grade and therefore have a very different
appearance. In order to minimize the impact on new
construction, full foundations will not be mandatory. Rather,
' substantial foundation plantings shall be required to screen the
base of the primary and secondary facade of any new building.
The first floor elevation shall be constructed a minimum of one
' and one half (1 .5) feet above grade. Grade shall be
determined at the high point of the sidewalk. In addition,
ground mounted mechanical units shall be screened with
plantings. Evergreen shrubbery is recommended as the most
appropriate type of planting for screening .
Facade Orientation In keeping with the existing pattern of development, new
structures shall continue to be situated at right angles with the
street. Primary facades shall be required to be parallel with the
street to which they front and buildings shall be oriented
perpendicular to the front facing facade.
WIDTH Width requirements are necessary to maintain the scale and
REQUIREMENTS rhythm of the district. The following requirements are based on
the existing averages of side yards, building widths, and lot
widths found inside the district. The average side yard was
calculated by means of aerial photographs and was determined
to be 27 feet. The average building width for the district was
also determined by use of aerial photographs. Buildings which
1 face north-south streets average 32 feet in width. Buildings
facing east-west streets have an average width of 33 feet. The
average lot width for the district is 62.3 feet.
' Lot Width No lot may be created which has an average width or street
frontage of more than 120 feet.
Building Width A maximum building width shall be used to preserve the scale
and rhythm in the district. The maximum allowed width of any
' building constructed within the district shall be seventy-six (76)
feet. Although a building width requirement of 76 feet is far
more than the district average building width, it does place
some limitations of wide buildings on the streetscape. The
distance of 76 feet was determined because it works well with
typical building patterns and with the required facade
treatments of the compatibility standards.
' Facade Width/Setback Primary facades shall have width and recess requirements for
the purpose of maintaining the rhythm of the streetscape and
Page 13
Central Ames Compatibility Standards
' to prevent the `blank wall" effect of large uninterrupted
expanses of wall.
' The primary facade of a building shall have a width between the
range of twenty-four (24) feet and thirty-eight (38) feet. Any
portion of the building which is wider than the primary facade
' shall be recessed from the primary facade a distance of not
less than eight (8) feet. A second primary facade will be
permitted, provided that it is separated by a recessed facade
' which conforms to the minimum facade width of twenty-four
(24) feet
HEIGHT A height maximum shall be placed on all buildings in order
REQUIREMENT'S to sustain the single-family nature and general scale of the
structures located within the district.
The maximum height of any new structure shall be no greater
than three (3) stories and/or forty (40) feet,
APPLICABILITY The Central Ames Compatibility Standards shall apply to all
new construction inside the Overlay District, New buildings
shall be constructed in full compliance of these standards.
Building additions shall be constructed in compliance with the
compatibility standards. However, building additions or
remodeling shall not mandate that existing structures be
brought into full conformance, only that they do not increase the
level of nonconformance_
