The purpose of this article is to describe the
design and construction standards applicable to land use activities
regulated by this chapter.
A.
The standards herein shall be considered to be minimum standards. When literal compliance with the standards and requirements contained in this chapter is clearly not appropriate, the Board of Supervisors may grant a modification of requirements from such requirements under the provisions of Article IX of this chapter.
A.
Land to be subdivided or developed shall be of such
character that it can be used safely for land development purposes
without danger to health, or peril from fire, flood or other menace.
B.
Land subject to hazards such as quarry land, open
ditches and ponds, having side slopes in excess of two horizontal
to one vertical having embankments of three or more feet in height
and the like, shall not be subdivided for residential purposes until
such hazards have been eliminated, or unless safeguards against such
hazards are provided, which are deemed adequate by the Township.
A.
Monuments must be placed so that the scored or marked
point coincides exactly with the point of intersection of the lines
being monumented.
B.
Monuments and markers must be set so that the top
of the monument or marker is level to one inch above the finished
grade.
C.
Monuments must be set at points of intersection in
the perimeter of a subdivision or land development, or at maximum
intersection intervals of 1,000 feet. If points of intersection occur
at intervals of more than 1,000 feet, the 1,000 feet spacing between
the points of intersection is waived.
D.
Street right-of-way lines shall be provided with monuments
at all points of intersection.
E.
Monuments shall be four inches square or four inches
in diameter and shall be 30 inches long.
F.
Monuments shall be made of concrete, stone or by setting
a four inch metallic pipe filled with concrete. Monuments which are
not constructed by filling a four inch metallic pipe shall have embedded
a metallic bar and/or cap to facilitate locating the monument with
electronic locating devices.
G.
Markers must be set at all lot corners except those
monumented, and must be placed before the property is offered for
sale.
H.
Markers shall be 3/4 of an inch square or 3/4 of an
inch in diameter, 30 inches long. Markers shall be made of iron or
steel bars.
I.
All markers and monuments shall be placed by a registered
surveyor.
A.
To the largest degree feasible, natural vegetation
shall be retained and protected.
B.
Stripping of vegetation, regrading or other development
activities shall be done in such a manner as will minimize erosion
and be in accordance with the approved soil erosion and sedimentation
control plan.
C.
On any property being developed pursuant to the provisions
of this chapter, no healthy tree with a trunk diameter equal to or
greater than eight inches measured 36 inches above the ground shall
be removed except for agricultural pursuits, foundations, roads, driveways,
access drives, parking facilities, active public or commercial recreation
areas, sidewalks and walkways, achieving clear sight lines for street
and driveway intersections and utility placement, unless such tree
removal is authorized by the Board of Supervisors as part of the plan
approval. When authorized to remove such trees, the developer shall,
at the Township's request, be required to plant a tree for each tree
removed, at a location approved by the Township, which may be located
on the lands being developed or any publicly owned lands of the Township.
D.
In the event that a developer or builder does not
clear the affected land in accordance with the approved plan, the
Township may issue a cease and desist order, and may revoke the approval
of the development plan and/or building permit for the subject land.
A.
To provide suitable sites for building and other uses,
and to improve surface drainage and control erosion, the following
requirements shall be observed during earth-moving activities:
(1)
The design of the land use activity shall preserve,
to the greatest extent practical, the natural features of the land,
and shall minimize land cuts and fills.
(2)
All land shall be graded to provide proper drainage
away from buildings, and to disperse water without adversely affecting
downstream properties.
(3)
All development activities shall be graded so as to collect and control stormwater as specified in Chapter 174, Stormwater Management.
[Amended 12-21-2010 by Ord. No. 602]
(4)
Where drainage swales are used to carry surface water,
they shall be sodded or otherwise constructed and protected so as
to be stable and noneroding.
(5)
Adequate provisions shall be made to minimize surface
water from damaging the cut face of excavations or the sloping surfaces
of fills.
(6)
Cuts and fills shall be designed to not endanger adjoining
property or public right-of-way.
(7)
Fills shall be placed and compacted so as to minimize
sliding or erosion of the soil and shall not encroach on natural watercourses
or drainage swales.
(8)
When adjacent to natural watercourses or drainage
swales, cuts and fills shall have suitable protection against erosion
during periods of flooding.
(9)
Trenches shall be backfilled in such a manner to minimize
settlement. This represents Township minimum standards and shall not
supersede any more stringent requirements of any other utility and/or
agency which may apply, such as the Derry Township Municipal Authority's
"Standard Construction and Material Specifications for Wastewater
Collection System Extensions," 1993, or as may be amended.
(10)
Settlement shall be minimized by placing fill
material in loose lifts not exceeding eight inches and compacted to
its optimum moisture content, plus or minus two percentage points,
to 95% of its maximum dry density as determined by the modified proctor
compaction test ASTM Designation D-1557-70.
(11)
Each compacted lift in a public right-of-way
may be inspected by the Township or its representative before placing
additional fill material.
(12)
Grading equipment shall not cross permanent
streams.
B.
In the event a developer initiates earth-moving or
other activities which disturb the site, and the developer's failure
to complete the development as scheduled creates the potential of,
or an actual environmental hazard, or is otherwise detrimental to
the health, safety and welfare of the public, and it appears the developer
has abandoned serious development activities at the site, the Township
may give the developer a written notice stating that the developer
must take corrective action to eliminate the potential or existing
harm within 10 days of receipt of said notice, or the Township will
proceed to take corrective action to do so. If the developer fails
to initiate good faith corrective action by the 10th day after receiving
said written notice, the Township may take the minimal corrective
action necessary to protect the health, safety and welfare of the
public, and may charge developer's performance security for the costs
of the same if not reimbursed by the developer within 30 days of receipt
of a written request for payment of the costs of the corrective work,
including engineering and administrative costs. Such written request
for payment shall be accomplished by a complete itemization of the
cost incurred. In an emergency situation, when the threat of harm
is immediate, notice to take corrective action may be made by telephone
or direct verbal communication and the Township may take immediate
action if the developer fails to indicate they will promptly undertake
the appropriate corrective action. In an emergency situation the Township
may act without giving actual notice if it has made reasonable attempts
to do so without success and the potential danger from failure to
act would be imminent and substantial in nature.
A.
An erosion and sedimentation control plan shall be included with preliminary and final plan submissions and shall consist of such graphic plans, details, calculations, written narrative, etc., as necessary to explain the proposed earth disturbance activity and demonstrate compliance with the requirements of the Pennsylvania Department of Environmental Protection, "Erosion Control Rules and Regulations" (Title 25, part I, Subpart C, Article II, Chapter 102 — Erosion Control). The design criteria and requirements for the erosion and sedimentation control plan may be obtained from the Dauphin County Conservation District, or directly from the Pennsylvania Department of Environmental Protection.
B.
The plan shall be submitted to the Dauphin County
Conservation District for review with evidence of such submission
forwarded to the Township. A letter indicating that the plan complies
with the relevant Department of Environmental Protection rules and
regulations may be required by the Township prior to final plan approval.
When an earth disturbance permit is necessary, the Township may require
the issuance of said permit prior to final plan approval.
C.
Construction shall be in accordance with the approved
erosion and sedimentation control plan. Controls shall be installed
at the initial stages of earth-moving activities and shall remain
in effect until final stabilization of the project occurs.
A.
General.
(1)
The design of all streets shall, at a minimum, conform
to this chapter and all other applicable standards and specifications.
(2)
All proposed streets shall be considered in their
relation to existing streets, to planned streets, to the Derry Township
Comprehensive Plan, to topographical conditions, to public conveniences
and safety and to their appropriate relation to the proposed uses
of the land to be served by such streets.
(3)
Private streets are prohibited except to the extent that common driveways are permitted as part of a conditional use grant for a cluster development as described in § 225-501.43 of Chapter 225, Zoning; or as part of a conditional use grant for a master plan development as described in § 225-501.58 of Chapter 225, Zoning.
[Amended 3-28-2017 by Ord. No. 684]
B.
Street classification.
(1)
Four functional classifications of public streets
are established as follows:
(a)
Arterial. This classification includes public
streets which provide intercounty and intermunicipal traffic of substantial
volumes.
(b)
Collector. This classification includes those
public streets which connect minor public streets to arterial public
streets and which generally serve intra-county and intra-municipal
traffic. They may serve as traffic corridors connecting residential
areas with industrial, shopping and other services. They may penetrate
residential areas.
(c)
Minor. This classification includes those public
streets that provide direct access to abutting land and connections
to higher classes of public streets. Traffic volumes will be low and
travel distances generally short.
(d)
Alley. This classification includes those public
streets that are primarily used for service or parking access to the
rear or side of a property.
(2)
The Township shall determine the street classification
based on existing proposed and anticipated conditions. The developer
shall meet with the Township prior to preparing a preliminary plan
to obtain necessary classification information.
C.
Street system design.
(1)
The arrangement of streets in new subdivisions or
land developments shall make provisions for the continuation of existing
streets from adjoining areas.
(2)
Where adjoining areas are not developed, the arrangement
of streets in the proposed subdivision or land development shall make
provision for appropriate projection of streets by constructing them
to the boundary between the new development and adjoining areas or
by providing an area reserved for future street extensions, unless
the future projection of such streets is clearly impractical.
(3)
Streets terminating in a cul-de-sac shall not exceed
500 feet in length and shall not serve more than 14 dwelling units.
Not more than 20% of the dwelling units in a development shall be
served by streets terminating in cul-de-sacs.
(4)
The cul-de-sac portion of streets shall be provided
with a paved turnaround having a right-of-way and paving radius as
specified in Table 185-22.
(5)
Dead-end streets shall be permitted only when terminated
in a permanent cul-de-sac.
(6)
If a developer chooses to develop an area represented
on an approved preliminary plat in stages, and streets are planned
to extend into other sections represented on the preliminary plat,
temporary cul-de-sacs shall be provided for a period of use not to
exceed three years.
(7)
Temporary cul-de-sacs shall be stabilized all weather
turnarounds having the same radius as required for a permanent cul-de-sac.
Minimum stabilization shall consist of an eight inch 2-RC stone base
on a natural or compacted subgrade.
(8)
When temporary cul-de-sacs are proposed, security
guarantees must be provided to the Township to ensure that if, after
the three years, the street is not extended, the cul-de-sac will be
improved to a permanent type of construction, complete with curbs
and sidewalks.
(9)
When establishing phase lines for preliminary plan,
the phase lines shall be laid out so that if the development does
not progress beyond any particular phase, the streets will not remain
as streets terminating in a cul-de-sac which are contrary to the street
design standards contained herein.
(10)
Reserve strips providing an area reserved for
future marginal access streets may be required along collector or
arterial streets.
(11)
A development activity which abuts a collector
or arterial street may be required by the Township to use marginal
access streets, double frontage lots or such other design which will
reduce the number of street or driveway intersections with collector
or arterial streets.
(12)
Half or partial streets will not be permitted.
(13)
Whenever a tract to be developed borders an
existing half or partial street, the other part of the street shall
be plotted within such a tract.
(14)
All lands subdivided and/or all lots developed
which are to be the site of 10 or more dwelling units shall provide
for at least two street connections to existing public streets.
(15)
In situations involving the subdivision or development
of land for nonresidential purposes, the Board of Supervisors may
require at least two street connections, or if the land is to be accessed
by driveways, two driveway connections to existing public streets
where necessary to ensure safe and efficient traffic flow.
D.
Street right-of-way and cartway widths.
(1)
Based on the criteria provided in § 185-22B of this article, the Township shall determine whether a street shall be classified as an arterial, collector, minor street or alley.
(2)
Street right-of-way and cartway widths shall not be
less than as shown on Table 185-22.
(3)
Additional street width (right-of-way, cartway, or
both) may be required to be dedicated adjacent to existing streets
with substandard right-of-way of cartway widths with respect to Table
185-22 of this article, in specific cases for:
(4)
Short extensions of already existing streets with
right-of-way or cartway widths less than the requirements above may
be permitted provided the Board of Supervisors determines that such
an extension would be reasonable and necessary for the orderly and
efficient completion of the street.

The developer shall notify the Township a minimum
of 24 hours in advance of the start of curb construction.
(5)
Existing adjacent streets abutting development sites
shall be provided by the developer with curbing along the abutting
side of any adjacent street. Restoration or placement of paving between
the curbing and the existing cartway shall also be provided by the
developer.
F.
On-street parking. Streets shall provide street widths
and right-of-way widths to accommodate parking as specified in Table
185-22.
G.
Street alignment and grade.
(1)
Streets shall be logically related to the terrain
and topography so as to produce usable roads with reasonable alignments
and grades.
(2)
Horizontal street alignments shall be measured along
the centerline. Horizontal curves shall be used at all angle changes
in excess of one degree, and shall have a minimum length of 50 feet.
Single, long radius curves shall be used rather than a series of curves
with varying radii and/or a series of short curves separated by short,
straight segments.

Specifications, Form 408, 1994, as amended.
J.
Retaining walls adjacent to right-of-way. Retaining
walls adjacent to the right-of-way shall be placed a minimum distance
from the right-of-way line that would allow the angle of natural repose
of the material being retained to not encroach on the right-of-way
area if the retaining wall would fail or be removed. All such retaining
walls shall be designed by a professional engineer licensed in the
Commonwealth of Pennsylvania.
K.
Minimum sight distance requirement.
(1)
The minimum vertical and horizontal sight distance
at intersections of streets and driveways shall be measured and provided
as shown in Appendix C-1[2] as minimum sight distance requirements.
[2]
Editor's Note: The Appendices and Sample Documents
are included at the end of this chapter.
(2)
If the minimum sight distance can be achieved only
by a line of sight across lands which are not public street rights-of-way,
a clear sight easement shall be established and recorded with the
deed of each affected property. The easement shall prohibit the existence
of structures, vegetation, or change in grade in excess of 24 inches
in height within the clear sight easement. The easement shall establish
the right of the Township to enter and remove any above described
obstructions at the property owner's expense if, after being notified
by the Township to remove said obstructions, the property owner fails
to respond.
L.
At-grade intersections.
(1)
Streets shall be laid out to intersect at right angles.
(2)
The Township may require additional traffic lanes
to facilitate vehicular turning movements at existing or proposed
street intersections which are affected by the development activity.
(3)
Intersections involving the junction or crossing of
more than two streets are prohibited.
(4)

The distance between the centerline of streets intersecting
at grade with an arterial street shall be no less than 600 feet measured
along the centerline of the street being intersected.
(8)
Where the centerline grade of any street approaching
an intersection exceeds 7% a leveling area shall be provided with
a grade not greater than 4% for a distance of not less than 50 feet
measured from the nearest right-of-way line of the intersecting street.
(9)
The minimum curb radii at street intersections involving
minor streets shall be 20 feet. Intersections involving collector
or arterial streets shall have minimum curb radii of 35 feet.

Driveway entrances or aprons within the street
right-of-way shall be surfaced with asphalt or concrete to their full
width.
M.
Street names and signs.
(1)
Streets shall be provided with street name signs at
all intersections. The signs shall identify the names of each street
involved in the intersection.
(2)
Such signs shall conform to Township specifications
as set forth in the Appendices of this chapter[3] and shall be installed by the developer at the developer's
expense.
[3]
Editor's Note: The Appendices and Sample Documents
are included at the end of this chapter.
(3)
Names of new streets shall not duplicate existing
or platted street names, or approximate such names by the use of suffixes
such as "lane," "way," "drive," "court" or "avenue." In approving
the names of streets, cognizance should be given to existing or platted
street names within the postal delivery district served by their local
post office. New streets shall bear the same name of any continuation
of alignment with an existing or platted street.
(4)
Final selection of street names shall be made by the
Township although proposals are encouraged to be made by the developer.
