A.
Intent. The intent of the Traditional Neighborhood District is to
create a design framework for new or infill residential development
that generally includes a interconnected network of streets and blocks,
a clear neighborhood center, a mix of uses and housing types, a compact
form of pedestrian-oriented design with an emphasis on quality civic
or green spaces.
B.
Purpose.
(1)
The purpose of the Traditional Neighborhood District is to create
a residential zoning classification that encourages a pattern of neighborhood
development that was commonly built in Steelton in the early 1900's.
These neighborhoods are characterized by a diversity of housing types
integrated with pathways to schools, parks, civic spaces and commercial
uses. This traditional pattern is based on a pedestrian environment
that is more people-friendly than auto-oriented and incorporates attractive
streetscapes. Parks and small green spaces are amenities throughout
the district that are accessible by pedestrian and bicycle transportation.
(2)
This zoning district includes both design standards (mandatory elements
of a traditional neighborhood) and design guidelines (desired elements
of a traditional neighborhood which may vary depending on the individual
development). Design standards are part of requirements of the district,
which design guidelines are recommended techniques for achieving the
standards and are advisory.
C.
Permitted uses.
(1)
All types of residential uses up to three multifamily and mixed uses.
(3)
Commercial uses, including:
(a)
Commercial child or adult day-care centers.
(b)
Personal services.
(c)
Professional, business or administrative offices.
(d)
Fitness center.
(e)
Music/art/cultural studios.
(f)
Bed-and-breakfast establishments.
(g)
Eating establishments excluding taverns and drive-through establishments.
(h)
Day care, child or adult.
(i)
Retail, including grocery stores, pharmacies, bakery, bookstores,
gift shops, newsstands, specialty food stores, florists, art galleries,
studios and shops of artists.
D.

F.
Traditional neighborhood principles. Although each neighborhood of
Steelton has its own differences, there are a number of basic, fundamental
principles found in traditional neighborhood designs. These principles
can be summarized with respect to: land use; streets; streetscape;
architecture and design.
(1)
Land use. Residential use is the basic building block of this zone.
A diversity of residential types, styles, and densities can exist.
A diversity of housing types per block gives neighborhood homeowners
the opportunity to move to different types of housing within the same
neighborhood depending on their state in life, such as young couples
moving to homes with yards for children. These options support a wider
range of housing prices, thus increasing the supply of dwellings available
to households of modest means. The compact, walkable nature of a traditional
neighborhood is supported by the opportunity of its residents to have
nonvehicular access to neighborhood services, facilities, and outdoor
spaces. A wide range of parks and small green spaces are requirements
of a traditional neighborhood to establish the identity and focus
for each individual neighborhood.
(2)
Streets. The street system of a traditional neighborhood is an integral
part of a design process and is the key element in maintaining or
creating a neighborhood. Streets must encourage alternative modes
of transportation, including automobile, pedestrian, transit, bicycle.
Must have a high level of connectivity to adjacent and neighboring
street systems either existing or proposed. Numerous ingress, egress
and internal circulation are required. Safety, utilities, street network
and level of service identifying street classification must be addressed.
In Steelton there are three types of streets existing or potentially
proposed in designated traditional neighborhood districts: main streets,
neighborhood streets and alleys. Adequate sight triangles at all intersections
shall be designed.
(a)
Main streets. The main street provides access to higher density
residential and commercial and mixed uses. Alleys are required. Most
often this type of street will contain utility infrastructure that
serves the greater demands of the commercial uses as well as mixed
residential uses. Main streets must retain a forty-two foot minimum
cartway width (curb to curb) to which on-street parking is expected.
Streetlighting and tree installation are required and should be consistent
with the Steelton streetscape design guidelines.
(b)
Neighborhood streets. A neighborhood street will serve residential
land uses ranging from single-family to multifamily residential dwelling
unit types. Neighborhood streets must retain a thirty-two-foot street
cartway width (curb to curb) to which on-street parking is expected.
A minimum of 66 feet is required between building faces on opposite
sides of the street. This 66 feet includes (on both sides of the street)
a five-foot easement for dry utilities; five-foot sidewalk; seven-foot
tree lawn and fire hydrant and lighting area; and the thirty-two-foot
street cartway. Streetlighting and tree installation are required
and should be consistent with the Steelton streetscape design guidelines.
The utility easement is not required if dry utilities are located
in an alley. Water and wastewater infrastructure can be located within
the thirty-two-foot street cartway width or located in alleys.
(c)
Alleys. Shall provide access to rear parking, residential parking
lots and garages, service and delivery vehicles. Dead-end alleys are
prohibited. There shall be a minimum of 30 feet of distance between
building faces on opposite sides of the alley. Dry utilities, large
telecommunication vaults and electric meters should be located in
alleys. Alleys must retain a sixteen-foot cartway plus must maintain
an unobstructed six-foot utility easement on both sides of any alley.
Alleys should be no greater than 400 feet in length. Utilities are
not restricted to the required alley length. All alleys shall be paved.
Landscaping materials shall be limited to ground covers, shrubs, annuals
and perennial plants and flowers.
(3)
Streetscape. The streetscape is defined as that area that lies between
the street curb and the front facade of the adjacent buildings. The
combination of the adjacent land uses, with the public and semi-public
spaces of the streetscape, are what make the street a dynamic and
inviting space to the pedestrian. The streetscape design will address
the following:
(a)
The proportional relationship between the street width and the
building height.
(b)
The building-to lines and the structures that define this line.
(c)
The semi-public space.
(d)
The public realm.
(e)
The tree lawn improvements.
(f)
Street furniture.
(g)
Off-street parking.
(h)
Garage placement.
(i)
Streetscape design standards:
[1]
The build-to line shall be designated on the development plan.
Each building's primary facade shall be set on the build-to line.

plan, including benches, trash receptacles, streetlighting.
[3]
Transit should be incorporated into the development plan, including
signage and shelters.
[4]
Street trees should be maintained to provide 14 feet of vertical
clearance above driving lanes and eight feet above sidewalks.
(4)
Architecture and design. Building design must be architecturally
distinctive, enhancing to the streetscape and must create definitive
character for its neighborhood. Elements such as front porches, rear-loaded
garages, front door stoops, and pedestrian scale wooden picket style
fencing must be incorporated into each housing plan. The following
architecture and design standards are required:
(a)
Existing streets within a traditional neighborhood zone are
classified as neighborhood streets.
(b)
Public and private lighting systems.
(c)
Shielded light fixtures in parking lots.
(e)
Front porches shall be included for all one- and two-family
homes. Front porches shall have a minimum depth of five feet and shall
have a minimum area of 50 square feet. A second story area above a
first story porch that encroaches into a build-to zone may be constructed
as a balcony but shall not be roofed or enclosed, except with a porch
railing or porch wall. Porch walls may be opaque and porch railings
shall not exceed 42 inches in height. One-story porches shall be allowed
to encroach into the build-to zone, but shall not be allowed into
the public right-of-way or a dedicated easement.
(f)
As an incentive for incorporating porches into the development
plan, up to 50 square feet of the porch area shall be excluded from
calculations to measure lot coverage.
(g)
All residential units shall have at least one entrance oriented
towards the front build-to line. A building front entrance may not
front on an alley.
(h)
Front porches shall be open on the streetside and any enclosures
on the sides above any porch wall shall be transparent.
(i)

of architectural features and stepping back upper floors.
[x]
The front of the building should have the greatest
articulation.
[xi]
For commercial space, a minimum of 50% of the
area of the front facade on the ground floor shall be transparent,
consisting of office or display windows, door openings both allowing
