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.
B. 
Proposed land uses shall comply with Chapter 225, Zoning.
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:
(a) 
Public safety and convenience.
(b) 
In commercial and industrial areas or in high density residential development.
(c) 
Widening of existing streets which do not meet the requirements of this section.
(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.

Alley
75 feet
(4) 
Vertical curves shall be used in changes in grade exceeding 1%. The minimum lengths (in feet) of vertical curves shall be 15 times the algebraic difference in grade. For example, if a 3% upgrade is followed by a 4% downgrade, the algebraic difference in grade is 7 [+3-(-4)=7]; the minimum length of the vertical curve would then be 105 feet (15 by seven equals 105).
(5)

(2) 
When required, guide rail shall meet PennDOT specifications for the Strong Post Type 2 system, and shall be installed in accordance with § 620 of the Pennsylvania Department of Transportation 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.

(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.
[Amended 4-10-2007 by Ord. No. 562]
