[HISTORY: Adopted by the City Council of the City of Harrisburg
by Ord. No. 23-1990. Amendments noted where applicable.]
The applicant shall provide all improvements required by these
regulations pursuant to the specifications for the improvements contained
herein or in the City Engineering Specifications or in Title 9, Public
Works, of these Codified Ordinances.
C.
Monuments and markers shall be the following sizes and made of the
following materials:
(1)
Monuments shall be six inches square or four inches in diameter
and shall be 36 inches long. Monuments shall be made of concrete or
stone or by setting a four-inch cast or steel pipe filled with concrete.
(2)
Markers shall be 3/4 of an inch in diameter and 36 inches long.
Markers shall be made of iron or steel bars.
D.
Monuments and markers must be placed so that the scored or marked
point coincides exactly with the point of intersection of the lines
being monumented. They must be set so that the top of the monument
or marker is level with the finished grade of the surrounding ground.
Monuments must be marked on top with a copper or brass plate or dowel
set in the concrete.
A.
Streets must be surfaced to the grades and dimensions drawn on the
plans, profiles, and cross sections submitted by the applicant and
approved by the City Engineer. Before paving the street surface, the
applicant must install the required utilities and provide, where necessary,
adequate stormwater drainage for the street acceptable to the City
Engineer. The pavement base and wearing surface must be constructed
in accordance with Pennsylvania Department of Transportation Publication
70 and material specifications in Form 408.
B.
Driveway entrances or aprons within the street right-of-way shall
be surfaced to their full width. The width of access roads or driveways
shall be in accordance with the following standards:
(1)
For multifamily residential, mobile home parks, and all nonresidential
developments or subdivisions, access roads shall be no less than 24
feet in width at the street line and shall clearly be defined by the
use of curbing.
(2)
For single-family residential subdivisions, driveways shall
be no less than 10 feet in width and no greater than 20 feet in width
at the street line.
C.
Where proposed driveways provide access onto a state highway, the
design of such driveway access and drainage shall be prepared in accordance
with the requirements of the Pennsylvania Department of Transportation
and shall be subject to the approval and issuance of permits by that
Department.
D.
Where a driveway or access road gives access to a municipal street,
approval by the City Engineer shall be required and a highway occupancy
permit obtained.
E.
The curb height at driveway entrances may be reduced to a minimum of 1 1/2 inches for driveway entrances along streets where curbs are required. The maximum width of reduced curb height shall be 20 feet for residential driveways and 35 feet for commercial or industrial driveways. Sidewalks across driveway entrances shall be concrete, a minimum of six inches thick, of Class A concrete, six-inch by six-inch ten-gage steel reinforcing mesh laid with a minimum of two inches of cover, on a four-inch bed of Type 2A stone aggregate on compacted or undisturbed soil. These sidewalks shall also be constructed in accordance with the requirements of § 7-511.7 of this chapter.
F.
Intersection curb cuts shall be provided where sidewalks and curbs
are required for handicapped accessibility.
A.
Subdivisions and land developments located in the City shall connect
to City water and sewer. Private sewage disposal systems are not permitted
in the City.
B.
Sanitary sewers shall not be combined with stormwater sewers and
shall not be constructed to receive effluents from any stormwater
collection system.
A.
The applicant shall install storm sewers, culverts, and related facilities
as necessary to permit the unimpeded flow of the natural watercourse,
ensure the drainage of all low points along the line of streets, and
collect and convey stormwater runoff along streets at intervals reasonably
related to the extent and grade of the area drained.
C.
Where adequate existing storm sewer mains are readily accessible,
the subdivider must connect the development's stormwater facilities
to these existing storm sewer mains by means of a manhole.
D.
In the design of storm drainage facilities, consideration must be
given to prevent runoff onto adjacent developed properties. In no
case may a change be made in the existing topography which would result
in increasing any portion of the slope steeper than one foot of vertical
measurement for four feet of horizontal measurement for fills or one
foot of vertical measurement for four feet of horizontal measurement
for cuts within a distance of 20 feet from the property line unless
an adequate retaining wall or other structure is provided.
E.
All slopes must be protected against erosion.
F.
A street must be designed so as to provide for the discharge of surface
water from its right-of-way. The slope of the crown on a street shall
be 2% per foot. Adequate facilities must be provided at low points
necessary to intercept runoff.
G.
Storm drainage facilities shall be designed in accordance with the
City's Engineering Specifications.
Curbs shall be installed on each side of the street surface
in accordance with the following specifications:
A.
Curbs shall be constructed according to the specifications set forth
in Section 630 of the Pennsylvania Department of Highways Specifications,
1987, Form 408, of the Pennsylvania Department of Transportation,
as amended, except that fiber reinforcement shall be added to cement
construction IAW manufactures instructions.[1]

Editor's Note: So in original.
B.
Where vertical curbs are provided, they shall not be less than seven
inches wide at the top and eight inches wide at the bottom. The overall
depth of the curb shall not be less than 18 inches. Eight inches of
curb reveal at the street is required. Curbs must have expansion joints
every 20 feet and be placed between abutting material. The curb shall
rest on a six-inch crushed stone base or concrete footing at the joints
if, in the opinion of the City Engineer, conditions warrant. The City
may require that the curb material be of the same material as curbs
surrounding the site.
C.
Curbs shall be set and finished to the lines and grades given on
the approved drawings.
Sidewalks shall be installed on each side of the street in accordance
with the following specifications:
A.
Sidewalks shall be within the right-of-way of the street.
B.
Sidewalks must be at least four feet wide. In the vicinity of shopping
areas, schools, recreation areas and other such facilities, sidewalks
must be at least five feet wide and located within the street right-of-way.
However, where located next to an existing sidewalk, the width of
the existing sidewalk is to be continued.
C.
In order to provide for the drainage of surface water, sidewalks
shall slope from the right-of-way line toward the curb. Such slope
shall be 2% per foot.
D.
Concrete sidewalks shall have three-fourths-inch expansion joints
every 10 feet; the material shall be premolded in conformance with
the Pennsylvania Department of Transportation Form 408, Section 705.
Sidewalks must have contraction joints every five feet, or uniformly
as approved by the City Engineer. Additionally:
(1)
Expansion joints are to be placed wherever concrete abuts any
other material except soil.
(2)
Any structure (i.e., pole, manhole, etc.) placed in the sidewalk
must be surrounded by expansion joint material. An eight-inch clearance
around the object (forming a square) of expansion joint material is
also required.
(3)
An expansion joint is necessary where the sidewalk abuts the
curb.
E.
The City may require other material to be used that may be more appropriate
to the neighborhood character. The specifications for alternative
material and installation specifications must be approved by the City
Engineer.
F.
Sidewalks in residential zones shall be constructed of concrete,
a minimum of four inches thick of Class A concrete, in accordance
with the Pennsylvania Department of Transportation Form 408, Section
704. The concrete is to be laid on a four-inch bed of Type 2A stone
aggregate on compacted or undisturbed soil, in accordance with the
Pennsylvania Department of Transportation Form 408, Section 703.
G.
Sidewalks in nonresidential zones shall be constructed of concrete,
a minimum of six inches thick of Class A concrete, a minimum of six-inch
by six-inch ten-gage steel reinforcing mesh laid with a minimum of
two inches of cover, on a four-inch bed of Type 2A stone aggregate
