Editor's note—Ord. No. 25-05-575, § 1, adopted May 5, 2025, set out provisions intended for use as § 6.5. Inasmuch as there were already provisions so designated, said section has been codified herein as § 6.6 at the discretion of the editor.


6.1.1. - Purpose and Intent

The City Council finds that the timely exercise of judgment in the public interest by a public body of proposed new development or redevelopment is desirable. Accordingly, the public policy objectives of this article are to guide certain aspects of development in specific areas of the city, such as:

A.

The spatial relationships of structures and open spaces to each other.

B.

The appearance of buildings and open spaces as they contribute to the attractiveness, function, economy, and character of an area. Planning area design standards are intended to be uniformly applied to evaluate the appropriateness of proposed changes to an overlay district to:

1.

Protect and enhance the visual qualities and character of the district.

2.

Provide guidance to design professionals, property, and business owners undertaking construction in the district.

3.

Recommend appropriate design approaches.

4.

Provide an objective basis for review, ensuring consistency and fairness.

6.1.2. - Relationship to Underlying Zoning

A.

Overlay standards are supplemental to the underlying zoning standards otherwise established by this UDC.

B.

Development in overlay districts must conform to underlying zoning district standards in which they are located, as well as all the regulations of the applicable overlay district.

C.

If overlay standards conflict with other regulations in this UDC, or other ordinances or regulations, the overlay governs or prevails to the extent of the conflict.

6.1.3. - Approvals by the City Architect

When an overlay authorizes the City Architect approval, such approval must be given based on consideration of the proposal and its compliance with the purpose and intent of the overlay district.

6.1.4. - Maintenance and Building Code

A.

Ordinary Maintenance or Repair

Ordinary maintenance or repair of any exterior feature visible from a public street in an overlay district to correct deterioration, decay, or damage, or to sustain the existing form, and that does not involve a material change in design, material, or outer appearance thereof, does not require a building, sign, or land disturbance permit.

B.

Failure to Maintain or Repair

Property owners in overlay districts must keep all exterior portions of properties in good repair. Property owners must also keep all interior portions of properties in good repair when not doing so may cause or tend to cause the exterior portion of the property to deteriorate, decay, or become damaged, or otherwise to fall into a state of disrepair.

6.2.1. - General

A.

Purpose and Intent

1.

The City Council declares that the purpose and intent of this section is to establish a uniform procedure to provide for the protection, enhancement, preservation, unity of design, and use of places, sites, buildings, structures, streets, neighborhoods, and landscape features in the State Route 9 Overlay District in accordance with these provisions.

2.

This section is adopted to promote the health, safety, order, prosperity, and general welfare of the City's citizens through the regulation of design, aesthetics, location, bulk, size of buildings and structures, and the density and distribution of population.

A.

Purpose and Intent

1.

The Rural Milton Overlay District, including Birmingham Crossroads, applies to all properties within the area shown in Sec. 6.3.10.F. The City Council finds that historic rural areas and their scenic surroundings are important cultural, recreation, and economic assets critical to the public's long-term interest and hereby declares it to be the purpose of this section to recognize and to establish a procedure to protect and plan for the city's "crossroads communities" (the rural development pattern where commercial buildings are built at the intersections of two major roads and residences are built at the edges). The intent of this section and Sec. 6.4 is:

a.

To develop guidelines to preserve and perpetuate a rural crossroads community which includes Birmingham Crossroads, agricultural related uses, residential development, and existing commercial zoning districts within the overlay district based on the description and analysis of their setting;

b.

To preserve the integrity of the area, which developed during the late 19th century and early 20th century, through architectural design interpretation and application;

c.

To preserve and protect the rural, agrarian and equestrian character of crossroads communities and their surrounding areas;

d.

To preserve and to ensure the harmony and compatibility of the character of the area including its physical appearance, natural setting, and informal landscaping especially along the rural viewsheds, including the implementation of the Milton Trail Plan;

e.

To acknowledge and respect the environment's natural resources and visual qualities;

f.

To preserve open space;

g.

To preserve, encourage, and promote, through the built environment, the sense of place, the sense of ownership, the sense of identity, the sense of evolution, and the sense of community present in the area;

h.

To ensure existing design characteristics of crossroads communities and surrounding areas are the standard against which plans for new construction are judged for harmony, compatibility, and appropriateness;

i.

To encourage and ensure that contemporary development designs and materials are still compatible with the existing character of the area through their proportion, scale, design, style, placement, position, and architectural qualities;

j.

To develop a community setting that has individuality and is unique and does not imitate building types or styles unrelated to the crossroads community;

k.

To provide for the construction of buildings and spaces that are human in scale, welcoming, and approachable;

l.

To encourage containment of existing commercial areas, to provide for transition between commercial areas and residential areas, and discourage encroachment of the commercial areas into the residential areas; and

m.

To promote sustainable development.

2.

This section and Sec. 6.4 are adopted as part of a strategy designed for the purpose, among others, of preserving and protecting these areas and enhancing their important aesthetic appearance through regulatory measures, while advancing community development goals, promoting economic development and substantially protecting and promoting health, safety, order, prosperity, and general welfare of the City's citizens.

B.

Building Size, Orientation, Setback, Height, Scale and Parking

The design and layout of a commercial or non-single-family development must build upon and complement the design of crossroads communities as opposed to creating a new one. The size, orientation, setback, and scale of buildings are integral elements of crossroads communities. A building's orientation and placement must complement and relate to adjacent buildings, structures, and properties. The placement of buildings must create an informal grouping and relationship between them as opposed to being orderly and uniform. The location of a building must take into consideration its rural surrounding and take advantage of this by maintaining open views and spaces. Buildings must be in proportion, in scale and characteristic to their rural and natural setting. The building design and material must contribute to the style and feeling of its rural surrounding. The visual impact of parking must be minimized by placing it to the rear and by screening. Accessory structures such as outparcel buildings, accessory structures, fences, and walls must have architectural features and exterior materials consistent with the principal building and are not required to meet the requirements except for height listed in Sec. 6.3.4.G.4 below. Such developments must comply with the following:

1.

Building size.

b.

Accessory structures must be in the location that is least visible from a public street and must conform to underlying zoning district standards.

c.

Driveways must be perpendicular to the street.

3.

Setbacks.

a.

For all property and lots located adjacent to public rights-of-way and 400 feet or less from an intersection, buildings except for accessory structures must be set back no more than 20 feet from the edge of the required landscape strip or easements. This 20-foot front yard area may be developed with a combination of landscape and hardscape elements, such as plazas, fountains, benches, and tables. Additional shade tree plantings are encouraged within public gathering places and alongside pedestrian paths. Building setbacks must vary to create the informal crossroads community setting.

b.

For all property and lots located adjacent to public rights-of-way and more than 400 feet from an intersection, buildings except for accessory structures must be set back no more than 30 feet from the edge of the required landscape strip or easements. This 30-foot front yard area may be developed with a combination of landscaping and hardscape elements, such as plazas, fountains, benches, and tables. Additional shade tree plantings are encouraged within public gathering places and alongside pedestrian paths.

c.

Buildings within a development must have at least 20 feet of separation between buildings. This area must be developed as greenspace or with a combination of hardscape and landscaping.

d.

If a building in a development cannot front a public street and meet the requirements of this section because other buildings are located there and no more space is available along the public street, then the building may front on an internal street in the development. The standards in this section regulating a building's position and relation to the street apply to a building fronting an internal street. The internal streets will also have to meet the standards specified for the public right-of-way, including landscape and streetscape requirements.

4.

Height. The maximum building height is two stories with a maximum height of 30 feet from average finished grade to the bottom of the roof eave.

5.

Scale. For every 80 feet of building length on a single face, there must be variation in the exterior or as approved by the City Architect accomplished through the following means:

a.

For each 80 feet of building exterior wall, the building exterior and roof must be offset by at least 10 feet. Overhangs and roof lines must follow the building's location.

b.

For each 80 feet of building exterior wall, there must be a change in details, or a change in patterns, or a change in materials.

6.

Parking.

a.

Parking must be shared among users within a common development. Parking shall be reduced according to the shared parking standards of Sec. 9.1.3.A. Additional reduction in the number of parking spaces is encouraged.

b.

All parking spaces built in excess of the minimum number required by Sec. 9.1.2 must be constructed of pervious material.

c.

No on-site parking may be located in front of a building or between a building and the public right-of-way (see Sec. 6.3.4.B.2 for landscaping standards if parking is visible from the right-of-way). Parking must be adjacent to internal streets, not a public right-of-way.

d.

If an internal street is developed for use by the general public, one row of parallel or diagonal parking is allowed between the street and the curb.

H.

c.

No on-site parking may be located in front of a building or between a building and the public right-of-way (see Sec. 6.3.5.B.2 regarding landscaping if parking is in view from the right-of-way). Parking must be located adjacent to internal streets, not a public right-of-way.

d.

If an internal street is developed for use by the general public, one row of parallel or diagonal parking is allowed between the street and the curb.

G.

Building and Other Structure Design

Construction of buildings in styles and types not found in Milton is prohibited. Modern style using traditional elements and the reinterpretation of a style, rather than the mimicking of a style, is encouraged. Exaggerated or excessively large or small architectural elements are prohibited. Elements must be in proportion with the overall building. In addition, buildings must reflect a specific style and not mix elements of different styles. The design and architectural elements of the buildings must be compatible with those of the area.

The overlay district seeks to replicate the crossroads community pattern by having future nonresidential construction, built within 400 feet from the edge of the right-of-way of an intersection, include elements of the historic commercial buildings, and nonresidential buildings, constructed over 400 feet from the edge of the right-of-way of an intersection, include elements of the historic residential buildings.

6.3.10. - Characteristics of Rural Milton Overlay

A.

The Rural Milton Overlay is based on the overall setting and characteristics of the rural crossroads communities in the City. In order to determine their qualities, a visual survey was conducted of Crabapple and Birmingham, as well as commercial buildings in Hopewell and Arnold Mill, and the main crossroads communities in the City. Commercial development in the City has been historically located in the crossroads communities that developed at the intersection of two or more roads. In these communities, commercial uses are close to the intersection, with institutional uses, such as churches and schools, next to them and residential uses extending along the roads. Large tracts of agricultural land, with rural vistas and views, border the residential areas. Crossroads communities maintain their historic integrity, as well as their informal character, rural atmosphere, and charm.

Generally, the commercial buildings at the crossroads are oriented to the street, are close to the street and have varying setbacks (from zero to 20 feet). Buildings are grouped informally and asymmetrically to each other to form a village atmosphere. Parking is located to the side or to the rear. Landscapes and the space between the buildings are informal, asymmetrical, rural, and picturesque. They avoid modern styles that emphasize ordered plantings, over planting, and often geometric placement. Informality of place provides for human scale, comfort, and a welcoming atmosphere. The setting, building design, and architectural details are elements that maintain the value of the communities and contribute to the sense of place in the city. More than being a place for commerce, they provide the sense of identity, ownership, community, and evolution.

Many of the commercial buildings were built from the late 1800's to the late 1930's in various types and style and have a rural and agrarian character. The buildings are generally small, one story with a square or rectangular footprint. Buildings are in scale and in proportion to each other.

The principal building materials are brick and clapboard siding, however, stone is also used. The roofs are gable or hip and are made of standing seam metal or asphalt shingles. Many of these also have a small, recessed porch. Several window types are present including double-hung sash, casement, fixed and fixed with an arch. In the double-hung sash windows, the sashes are divided into six lites over six, 4/4 and 2/2. The windows are in proportion to the building and most have a vertical orientation. The doors are usually wood paneled doors with glass in the upper half. The entryways and main façades are more articulated than the rest of the buildings. This is achieved by recessing the entrance or flanking the door with sidelites and transom lites. The buildings have limited stylistic elements. Some of the features that are present include: round and square columns, frieze board, exposed rafter ends, and triangle gable braces.

B.

Crossroads communities blend with their surroundings and thus avoid abrupt beginnings and endings. Commercial buildings transition into smaller residential buildings. Uses also transition down from commercial to office and then to residential. Many residential buildings that extend along the roads are now being used for retail and office. These residential areas also share similar characteristics: they are one-story, oriented to the street, often a walkway leads from the street to the front door or from the driveway to the front door, and the driveway is perpendicular to the street. Parking is to the side or the rear. The buildings are set back 10 to 40 feet from the sidewalk. In addition, wood fences, retaining walls, and hedges often define the boundaries of the property.

C.

The houses themselves also have similar characteristics. The principal building material is wood clapboard siding, and some are made out of stone. The common roof forms are gable, cross gable, and hip and are made of standing seam metal or asphalt shingles. The houses are raised on a foundation. Most of these also have a front or wrap around porch. Most of the windows are double-hung sash with the sashes divided into six lites over six (6/6), 3/1, 9/9, 1/1, and 2/2. Some have sidelites and transom lites around the front door and fixed arched windows.

D.

Several house types are present, including: hall parlor, double pen, central hallway, gable ell cottage, new south cottage, Georgian cottage, bungalow, and side gable cottage. House type refers to the height of the house, as well as the general layout of the interior rooms.

E.

Many of these houses do not have a high style but rather have a vernacular interpretation of a style. Style refers to the external ornamentation and the overall form of the house. In many cases, style elements are associated with a certain house type. For instance, craftsman elements are present in bungalow type houses. The architectural features present in these houses, by style, are listed below and are discussed in this subsection.

1.

Greek Revival. Frieze board, round columns, Doric columns, flute columns, gable returns, corner pilasters, dentil molding, pedimented gable.

2.

Queen Anne and Folk Victorian. Decorative cut shingles, verge board, turned posts, ionic columns, porch with turned balusters, frieze board.

3.

Craftsman. Wood or brick battered columns on brick or stone piers, exposed rafter ends, overhanging eaves, gable braces, frieze board, gable returns.

F.

6.5.2. - Historic District Regulations

A.

Scope and Intent

The regulations set forth in this Sec. 6.5.2 are the H district regulations. The H district is intended to allow for a historic structure to be used, protected, renovated, and preserved, based on its historic value to the community. The H district may allow a specific, previous use to continue in a structure where that use would be considered nonconforming as defined in this UDC. This designation will help preserve the rich traditions of history and culture evident in Milton's original settlement.

B.

Use Regulations

Within the H district, land and structures must be used in accordance with its standards.

1.

When approving H district classification for a property, the City Council may designate as a condition of zoning any limitations on the use of the subject property or structures located thereon. If no such condition is included, the use of the subject property will be limited to the most intense use allowed on any property adjacent to the subject property.

2.

H district classification is only available for property on which a proposed historic use would be deemed non-conforming under the existing zoning classification. Existence of the historic use of the subject property may be established by, among other things, historic pictures of the subject property, deeds, bills of sale, and personal affidavits. If personal affidavits are submitted as part of the H district zoning application, such affidavits must be supplemental to other evidence of historic use and must not be the sole evidence of same.

3.

The proposed historic use must be limited to those historic structures identified on the subject property and must not be expanded.

4.

Any structure for which a non-conforming historic use is proposed must first be designated as historic by the City of Milton Historic Preservation Commission. The historic designation process must be completed before the City accepting a rezoning application for the subject property, unless the Director determines that it is in the best interest of the City to process the designation and zoning applications together because of the risk of probable demolition.

5.

The proposed historic use shall be compatible with the surrounding land uses.

6.

The proposed historic use shall not result in the removal of historical characteristics of the structure or site, including mature landscaping.

C.

Development Standards

In order to allow for the unique nature of the properties receiving the H district classification, there are no district-specific development standards. However, all other requirements of the subject property's overlay district and this UDC shall be maintained. In addition, the City Council shall consider the subject property's overlay district and this UDC as it pertains to the proposed historic use, and may adopt reasonable conditions of zoning with respect to the following, without the need for a variance:

1.

Maximum structure height.

2.

Minimum lot area.

3.

Maximum density.

4.

Minimum lot width.

5.

Minimum development frontage.

6.

Minimum lot frontage.

7.

Minimum heated floor area.

8.

Minimum front yard setback.

9.

Minimum side corner setback.

10.

Minimum side yard setback.

11.

Minimum rear setback.

12.

Accessory structure requirements.

Buffer requirements.

14.

Parking requirements.

15.

Parking lot tree requirements.

16.

Lighting requirements.

17.

Fencing requirements.

18.

Signage limitations.

Notwithstanding any provisions to the contrary found in this UDC, the zoning conditions adopted by the City Council will have precedence over any conflicting requirement, regulation or standard found in either the overlay district regulations or this UDC.
