[Ord. 154, 9/3/1985, § 705; as amended by Ord.
256, 5/24/2004]
1. General. Where earth moving activities are involved:
A. No subdivision or land development plan shall be approved unless.
(1)
There has been a plan approved by the Planning Commission that provides for minimizing erosion and sedimentation consistent with this section, and an improvement bond or other acceptable security in accordance with §
22-403 is deposited with the Township in the form of an escrow guarantee which will ensure installation and completion of the required improvements.
(2)
There has been a determination by the Planning Commission that
a plan for minimizing erosion and sedimentation is not necessary for
approval under this chapter.
B. The developer shall construct and/or install such drainage systems
as are determined necessary by the Borough Engineer to prevent erosion
damage, and to satisfactorily manage surface waters.
C. Measures used to control erosion, reduce sedimentation and manage
stormwater shall as a minimum meet the standards and specifications
of the Bucks County Conservation District and the Pennsylvania Department
of Environmental Protection. The Borough Engineer shall ensure compliance
with the appropriate specifications, copies of which are available
from the District. The Planning Commission may request a review by
the Bucks County Conservation District and ask for technical assistance.
2. The following measures are effective in minimizing erosion and sedimentation
and shall be included where applicable in the control plan:
A. Stripping of vegetation, regrading, or other development shall be
done in a way that will minimize erosion.
B. During and after construction, development plans shall preserve pertinent
natural features, keep out-fill operations to a minimum, and ensure
conformity with topography so as to create the least erosion potential
and adequately handle the volume and velocity of surface water runoff.
C. All disturbed areas and stockpiles of topsoil or fill which are to
be exposed for greater than 30 days shall be temporarily seeded with
rye seed or other suitable ground cover within seven days of disturbance
or stockpiling.
D. All disturbed areas which are steeply sloped (25% or steeper) or
where there is a severe potential for erosion shall be temporarily
mulched and seeded with rye seed or other suitable ground cover within
seven days of disturbance.
E. The permanent (final) vegetation and mechanical erosion control and
drainage shall be installed as soon as practical in the development.
F. Provisions shall be made to accommodate effectively the increased
runoff caused by changed soil and surface conditions during and after
development. Where necessary, the rate of surface water runoff will
be mechanically retarded.
G. Sediment in the runoff water shall be trapped until the disturbed
area is stabilized by the use of debris basins, sediment basins, silt
traps, or similar measures.
3. Drainage. In order to provide more suitable sites for building and
other uses, improve surface drainage, and control erosion, the following
requirements shall be met:
A. All lots, tracts or parcels shall be graded to provide proper drainage
away from buildings and dispose of it without uncontrolled ponding,
and all land within a development shall be graded to drain and manage
surface water without uncontrolled ponding, except as part of an on-site
stormwater management system where approved by the Planning Commission
upon advice of the Borough Engineer.
B. Where drainage swales are used to divert surface waters away from
buildings, they shall be sodded, planted, or otherwise suitably protected
as required and shall be of such slope, shape, and size as to conform
to the requirements of the State Department of Environmental Protection.
Concentration of surface water runoff shall be permitted only in swales,
watercourses, retention or detention basins.
C. No excavation shall be made with a cut face steeper than 3:1 (horizontal
to vertical), except under one or more of the following conditions:
(1)
The excavation is located so that a line having a slope of 3:1
and passing through any portion of the cut face will be entirely inside
the property lines of the property on which the excavation was made
and shall not result in property damage or be a hazard to adjoining
property, streets, alleys, or buildings.
(2)
The material in which the excavation is made is sufficiently
stable to sustain a slope of steeper than one horizontal to one vertical.
A written statement to that effect from a civil engineer, licensed
by the Commonwealth of Pennsylvania, is submitted to the Municipal
Engineer and approved by him. The statement shall affirm that the
site has been inspected and that the deviation from the slope will
not result in injury to persons or damage to property.
(3)
A concrete or stone masonry wall constructed in accordance with
approved standards is provided to support the face of the excavation.
D. No fill shall be made which creates any exposed surface steeper in
slope than one and one-half horizontal to one vertical, except when
the plan for subdivision or land development is accompanied by a written
statement prepared by a civil engineer, architect, or landscape architect
licensed by the commonwealth, certifying that he has inspected the
site and that the proposed deviation from the slope specified above
will not endanger any property or result in any property damage. The
plan and statement must be submitted to and approved by the Borough
Council upon advice from the Borough Engineer.
E. Adequate provisions shall be made to prevent surface water from damaging
the cut face of excavations and the sloping surfaces of fills.
F. Fills shall not encroach on natural watercourses or constructed channels.
G. Fills placed adjacent to natural watercourses or constructed channels
shall have suitable protection against erosion during periods of flooding.
H. Grading shall in no case be done in such a way as to divert water
onto the property of another landowner.
I. During grading operations, necessary measures for dust control must
be exercised.
J. Grading equipment shall not be allowed to cross live streams. Provisions
shall be made for the installation of temporary culverts or bridges
subject to the approval of the Department of Environmental Protection.
K. Storm drains and appurtenances may be required to be constructed
by the developer to take surface water from the bottom of vertical
grades and to avoid excessive use of cross gutters at street intersections
and elsewhere.
L. The top or bottom edge of slopes shall be a minimum of five feet
from property or right-of-way lines of streets or alleys in order
to permit the normal rounding of the edge without encroaching on the
abutting property.
M. In the design of storm sewerage systems, the future use of undeveloped
areas upstream within the total drainage areas shall be taken into
account in calculating pipe size.
N. Stormwater retention and/or detention basins shall be designed to
facilitate regular maintenance, mowing, and periodic desilting and
reseeding. Basins shall not be located within floodplains and floodplain
soils shall be avoided.
O. In residential subdivisions, residential developments, and mobile home parks, shallow broad basins are preferred to steep-sided basins. The area of basins which have more than 50% of the perimeter of their sides in slopes of greater than 5% or basins which retain stormwater for more than 24 hours shall not be included in the open space required in the Borough Zoning Ordinance [Chapter
27].
4. Responsibility.
A. Whenever sedimentation is caused by stripping vegetation, regrading
or other development, it shall be the responsibility of the person,
corporation, or other entity causing such sedimentation to remove
it immediately from all adjoining surfaces, drainage systems, and
water courses and to repair any damage at his expense as quickly as
possible.
B. Maintenance of all drainage facilities and watercourses, both existing
and proposed, within any proposed subdivision, land development, or
mobile home park, shall be the responsibility of the developer until
such time as one of the following is accomplished:
(1)
An easement for these facilities is offered for dedication by
the developer and is accepted by the Borough, it shall then be the
responsibility of the Borough.
(2)
A deed restriction acceptable to the Borough is established.
In the case of a subdivision, the maintenance shall then be the responsibility
of the individual lot owners over whose property an easement passes.
For land developments, the maintenance shall then be the responsibility
of the owner.
(3)
A homeowners association, approved by the Borough, assumes responsibility
for the maintenance of the development, including the maintenance
of the watercourse and/or drainage facilities.
C. It is the responsibility of any person, corporation, or other entity
doing any act on or across a communal stream, watercourse or swale,
or upon the floodplain or right-of-way during the period of the activity,
to return it to its original or equal condition after such activity
is completed.
D. No person, corporation, or other entity shall block, impede the flow
of, alter, construct any structure, or deposit any material or thing,
or commit any act which will affect normal or flood flow in any communal
stream or watercourse without having obtained prior approval from
the municipality and/or Department of Environmental Protection, whichever
is applicable.
E. Each person, corporation, or other entity which makes any surface
changes shall be required to:
(1)
Collect on-site surface runoff and control it in a manner acceptable
to the Planning Commission upon advice from the Borough Engineer.
(2)
Handle existing off-site runoff through his development by designing
it to adequately handle one-hundred year, twenty-four-hour storm runoff
and any two, five or ten-year erosive type event from a fully developed
area upstream.
(3)
Pay his proportionate share of the total cost of off-site improvements
to the common natural watercourse, based on a fully developed drainage
area.
(4)
Provide and install at his expense, in accordance with Borough
requirements, all drainage and erosion control improvements (temporary
and permanent) as required by the erosion and sediment control plan.
5. Compliance with Regulations and Procedures.
A. The Planning Commission, in its consideration of all preliminary
plans of subdivision or land development, shall condition its approval
upon the execution of erosion and sediment control measures as contained
in this section.
B. The installation and design of the required erosion and sediment
control measures, listed below, shall be in accordance with standards
and specifications available through the Bucks County Conservation
District.

excess of 320 acres, or in those cases where downstream hazards exist,
shall be approved by the Pennsylvania Department of Environmental
Protection prior to development.
D. Final plans for minimizing erosion and sedimentation as approved
will be incorporated into the agreement and bond requirements as required
by the municipality.
E. The approval of plans and specifications for the control of erosion
and sedimentation shall be concurrent with the approval of final plats
of subdivision or land development, and become a part thereof.
F. At the time a building permit is applied for, a review shall be conducted
by the Engineer to insure conformance with the plan as approved. During
the construction, further consultative technical assistance will be
furnished, if necessary, by the Borough Engineer and the Bucks County
Conservation District. During this development phase, the Borough
Engineer shall inspect the development site and enforce compliance
with the approved plans.
[Ord. 154, 9/3/1985, § 706]
1. General.
A. At the time any application, petition or request is filed by any
person, partnership, association, or corporation for the approval
of the construction, opening, or dedicating of any proposed road or
street, the Borough shall be assured that said proposed street or
road shall be completed and said assurance shall be governed by the
provisions of § 609, as amended, of the Pennsylvania Municipalities
Planning Code.
B. Any person, partnership, association, or corporation making any application
or request for the approval of the construction, the opening, or dedication
of any proposed road, shall bear all costs of inspection of such roads
and any drainage facilities connected therewith, all engineering costs,
all costs of survey, and all other expenses and costs incidental to
construction, approval, and dedication of such street or road for
public use, including legal fees.
C. Proposed streets shall conform to such Borough and state street and
highway plans as have been prepared, adopted, and filed as prescribed
by law.
D. If lots resulting from the original subdivision are large enough
to permit resubdivision, or if a portion of the tract is not subdivided,
adequate street right-of-way, to permit further subdivision, shall
be provided.
E. Streets that are extensions of existing streets shall bear the names
of the existing streets. Street names shall not be repeated within
the Borough and all street names shall be subject to the approval
of the Borough Council.
F. Dead-end streets shall be prohibited, except as culs-de-sac.
G. A private road is permitted in the Borough for access to and from
no more than two single-family residential dwellings.
H. New half or partial streets shall be prohibited except where essential
to reasonable subdivision or land development of a tract in conformance
with the other requirements and standards of these regulations and
where, in addition, satisfactory assurance for dedication of the remaining
parts of the street is secured by escrow funds or surety bonds that
said construction will be completed.
I. Wherever a tract to be subdivided or developed borders on an existing
half or partial street, the other part of the street shall be platted
within such tract.
J. Any applicant whose property encroaches within the legal right-of-way
of a state highway is required to obtain a highway occupancy permit
from the Pennsylvania Department of Transportation.
K. Streets shall be logically related to topography so as to produce
reasonable grades, satisfactory drainage, and suitable building sites.
Streets shall be so arranged to be generally parallel to rather than
cross contour lines as well as to prevent the necessity for excessive
cut and fill. Streets shall be laid out to avoid hazardous areas such
as floodplains, steep slopes, and other hazardous natural features.
L. Where possible, streets shall be oriented east-to-west to provide
better solar access to lots.
2. Existing Streets.
A. Classification. Existing streets are classified in the Comprehensive
Plan. Unclassified streets shall be classified according to their
function, at the request of the applicant during plan review. The
Borough Council shall also refer to the Revitalization and Visioning
Plan for Dublin Borough when classifying streets.
[Amended by Ord. 312, 4/24/2017]
B. Dimensional Standards.

The cartway and right-of-way widths in this Part are minimum
requirements. Additional widths of right-of-way and/or cartway may
be required along the frontage of the proposed development if, during
the course of review, the Borough determines that these increases
are necessary to relieve traffic congestion and to provide safety
from fire and unsafe turning movements.
3. New Residential and Rural Streets - General.
A. Purpose. The purpose of these provisions is to establish appropriate
standards for the design of streets in residential subdivisions that
will:
[Amended by Ord. 312, 4/24/2017]
(1)
Promote the safety and convenience of vehicular traffic.
(2)
Protect the safety of neighborhood residents.
(3)
Minimize the long-term costs for the maintenance and repair
of streets.
(4)
Minimize crime in residential areas.
(5)
Protect the residential qualities of neighborhoods by limiting
traffic volume, traffic speed, noise and fumes.
(6)
Encourage the efficient use of land.
(7)
Minimize the cost of street construction.
(8)
Minimize the construction of impervious surfaces.
(9)
Meet the street design specified in the Revitalization and Visioning
Plan of Dublin Borough.
B. Street Hierarchy. The intent of this section is to create an integrated
residential street system by creating varying street standards within
which the designer may design a residential subdivision or land development.
The street hierarchy is related to average daily traffic (ADT) levels,
lot frontage, and the need for on-street parking. Except for streets
in the PVD Planned Village Development District, the following hierarchy
of new streets is hereby established:
[Amended by Ord. 312, 4/24/2017]
(2)
Residential subcollector.
C. Classification. Except for streets in the PVD Planned Village Development
District, new residential streets will be classified according to
the expected ADT level of the street. If subdivision lots are large
enough for further subdivision, the Borough Council may require that
the street be constructed to the standards of a higher classification,
unless deed-restricted against further development.
[Amended by Ord. 312, 4/24/2017]
D. Stub Streets. Stub streets will be permitted only within subsections
of a phased development as a temporary condition in which the stub
street is a portion of the overall street system.
E. Design Options.
(1)
Except for streets in the PVD Planned Village Development District,
all new residential streets shall be designed to meet the standards
in the Table of Street Design Options and the following sections for individual street types.
New residential streets in the PVD Planned Village Development District
shall meet the following and be consistent with the design sketch

street if the expected ADT from the new development will exceed the
allowable ADT level for that street classification.
(3)
Table of Street Design Options.
F. Trip Generation Rates. The Zoning Ordinance [Chapter
27], §
27-1308, Impact Statement, shall be used to determine trip generation rates.
G. Spillover Parking.
(1)
Spillover parking spaces are parking spaces that are needed
to accommodate the vehicles of infrequent visitors such as guests
or repairmen, when on-street parking is not provided for. These spaces
are required in addition to the number needed to accommodate the residents.
Spillover parking may be provided on the individual lots, in separate
parking areas, or in the common parking areas.
(2)
When off-street spillover parking is required in the Table of Street Design Options, it shall be provided at the following rates in addition to the minimum off-street parking requirements of the Zoning Ordinance [Chapter
27].
|

(3)
When spillover parking is provided on the individual lots, the
following criteria must be met:
(a)
Each space shall be 9 1/2 feet by 19 feet.
(b)
The spaces may be provided in the driveway or in a turn-around.
(c)
The spillover spaces shall be clearly shown and noted on the
subdivision or land development plan.
4. Residential Access Streets.
A. Residential Access Streets. This is the lowest order street in the
hierarchy. It is intended to carry the least amount of traffic at
the lowest speed. It will provide the safest and most desirable environment
for a residential neighborhood. Developments should be designed so
that all or the maximum number possible of the homes will front on
this class of street.
B. Service Restrictions. Each residential access street shall be designed
so that no section of the street conveys a traffic volume greater
than 200 ADT. Each half of a loop street may be regarded as a single
local access street, and the total traffic volume conveyed on a loop
street shall not exceed 400 ADT.
C. Street Access. A residential access street may intersect or take
access from any existing street type. Both ends of a loop street,
however, must intersect the same collecting street and be laid out
to discourage the passage of through traffic.
D. Street Width and Curbing. As required by the Table of Street Design
Options.
E. Shoulders. When curbing is not required, two-foot wide stabilized
shoulders shall be provided on both sides of the cartway.
F. Length of Cul-de-sac. No cul-de-sac shall exceed a length of 500
feet unless specifically authorized by the Council. Cul-de-sac length
shall be measured along the center line of the intersecting through
street to the center point of the turnaround.
G. Cul-de-Sac Turnaround. A paved area with an outside turning radius
of 40 feet shall be provided at the terminus of every permanent cul-de-sac.
Ring-shaped culs-de-sac shall provide a continuous twenty-foot wide
paved cartway. Other alternative designs may be approved, provided
that they meet these minimum radius and cartway width requirements.
Center line grade in the turn-around shall not exceed 4%.
H. Engineering Criteria. All features of the geometric design of residential
access streets that are not specified below shall be designed for
a design speed of 25 miles per hour.
(3)
Horizontal curvature: minimum center line radius of 100 feet.
(4)
Minimum tangent length between reverse curves: 50 feet.
(5)
Stopping sight distances: 175 feet minimum.
(6)
Maximum grade within 50 feet of intersection: 4.0%.
5. Residential Subcollector.
A. Residential Subcollector Street. This is the middle order street
in the hierarchy. It will carry more traffic than the residential
access street. It should provide an acceptable if not an optimum environment
for a residential neighborhood.
B. Service Restrictions.
(1)
Each subcollector street shall be designed so that no section
of it conveys a traffic volume greater than 500 ADT. (Each half of
a loop subcollector street may be regarded as a single subcollector
street and the total traffic volume conveyed on a loop street shall
not exceed 1,000 ADT).
(2)
Subcollector streets shall be designed to exclude all external
through traffic which has neither origin nor destination on a subcollector
or its tributary residential access streets.
C. Street Access. Every subcollector must be provided with no fewer
than two access intersections to streets of higher classification
in the streets hierarchy, namely existing or proposed collector roads
or arterial highways, if the total traffic volume exceeds 500 ADT
on the street. For subcollector streets designed not to exceed 500
ADT, a subcollector with one access intersection to a street of higher
order is allowed. In no case shall a subcollector end in a cul-de-sac.
D. Street Width and Curbing. As required by the Table of Street Design
Options.
E. Shoulders. When curbing is not required, two-foot wide stabilized
shoulders shall be provided on both sides of the cartway.
F. Moving Lanes. All subcollector streets shall be provided with two
continuous moving lanes within which no parking is permitted.
G. Engineering Criteria. All features of the geometric design of subcollector
streets that are not specified below shall be designed for a design
speed of 30 miles per hour:
(3)
Horizontal curvature: minimum center line radius of 140 feet.
(4)
Minimum tangent length between reverse curves: 100 feet.
(5)
Stopping sight distance: 200 feet minimum.
(6)
Maximum grade within 50 feet of intersection: 4.0%.
6. Residential Collector.
A. Residential Collector Street. This is the highest order street that
could be classed as residential. It will carry the largest volume
of traffic at higher speeds. In large residential developments, this
class of street may be necessary to carry traffic from one neighborhood
to another or from the neighborhood to streets connecting to other
areas in the community. This level of street is unsuitable for providing
direct access to homes and such access to homes should be avoided.
B. Service Restrictions.
(1)
Provision of a residential collector street or road system is
mandated whenever any proposed development is of sufficient magnitude
to render it impossible to meet the maximum anticipated service volume
(ADT) standards established for local access and subcollector streets.
Generally, a non-frontage collector may be necessary whenever a development
exceeds 150 dwelling units, or when it carries external through traffic
in addition to traffic generated by the development.
(2)
Residential collectors shall be laid out to discourage excessive
external through traffic, except where linkage between bordering roads
may be determined to be desirable as indicated in the Borough Comprehensive
Plan, or by the Borough during plan review. The Borough, upon recommendation
of the Borough Engineer, may impose additional standards on the design
of the roadway, if additional external through traffic shall so warrant.
(3)
Whenever possible, residential collector streets should be designed
to have no residential lots directly fronting on them. When this is
not possible, the amount of residential frontage per length of collector
street length shall not exceed the limits set forth in the accompanying
chart. In addition, only lots having frontages of 100 feet or greater
may front on collector roads, and space shall be provided on these
lots for turnarounds so that vehicles will not have to back out onto
collector roads.

C. Street Access. Every residential collector must be provided with
no fewer than two access intersections to streets of equal or higher
classification in the streets hierarchy.
D. Street Width and Curbing. Curbs should not be provided along residential
collector roads except as they are found to be essential for storm
water management. The width shall be provided as indicated in the
Table of Street Design Options.
E. Shoulders. Four-foot wide stabilized shoulders are required along

|
|
All others required by the Borough Zoning Ordinance [Chapter 27].
|
2. These impact studies will be reviewed by the Borough and must be
found to be satisfactory prior to granting preliminary approval. Any
improvements identified by the studies will be required improvements
at the time final plan approval is granted.
3. Traffic Impact Study. The study will enable the Borough to assess
the impact of a proposed development on the traffic system. Its purpose
is to ensure that proposed developments do not adversely affect the
traffic network and to identify any traffic problems associated with
access from the site onto the existing roads. The study's purpose
is also to delineate solutions to potential problems and to present
improvements to be incorporated into the proposed development. Traffic
impact statements shall be based on the following criteria:
A. General Site Description. The site description shall include the
size, location, proposed land uses, construction, staging and completion
date, or types of dwelling units. A brief description of other major
existing and proposed land developments within one-half mile of the
proposal which shall constitute the study area.
B. Traffic Facilities Description. The description shall contain a full
documentation of the proposed internal and existing highway system.
The report shall describe the external roadway system within the area.
Major intersections in the area shall be identified and sketched.
All future highway improvements which are part of proposed surrounding
developments shall be noted and included in the calculations.
C. Existing Traffic Conditions. Existing traffic conditions shall be
measured and documented for nil roadways and intersections in the
area. Existing traffic volumes for average daily traffic, peak highway
hour(s) traffic and peak development-generated hour(s) traffic shall
be recorded. Manual traffic counts at major intersections in the study
area shall be conducted, encompassing the peak highway and development-generated
hour(s), and documentation shall be included in the report. A volume/capacity
analysis based upon existing volumes shall be performed during the
peak highway hour(s) and the peak development-generated hour(s) for
all roadways and major intersections in the study area. Levels of
service shall be determined for each location. This analysis will
determine the adequacy of the existing roadway system to serve the
current traffic demand. Roadways and/or intersections experiencing
levels of Service E or F, as described in Report 87: Highway Capacity
Manual, Highway Research Board, 1965, shall be noted as congestion
locations.
D. Traffic Impact of the Development. Estimation of vehicular trips
to result from the proposal shall be completed from the average daily
peak highway hour(s). Vehicular trip generation rates to be used for
this calculation shall be obtained from the Trip Generation: An Informational
Report, Institute of Transportation Engineers. These development-generated
traffic volumes shall be provided for the inbound and outbound traffic
movements as estimated, and the reference source(s) and methodology
followed shall be documented. All turning movements shall be calculated.
These generated volumes shall be distributed to the area and assigned
to the existing roadways and intersections throughout the area. Documentation
of all assumptions used in the distribution and assignment phase shall
be provided. Traffic volumes shall be assigned to individual access
points. Any characteristics of the site that will cause particular
trip generation problems shall be noted.
E. Analysis of Traffic Impact. The total future traffic demand shall
be calculated. This demand shall consist of the combination of the
existing traffic expanded to the completion year (straight line projections
based on historical data), the development generated traffic, and
the traffic generated by other proposed developments in the study
area. A second volume/capacity analysis shall be conducted using the
total future demand and the future roadway capacity. If staging of
the proposed development is anticipated, calculations for each stage
of completion shall be made. This analysis shall be performed during
the peak highway hour(s) and peak development-generated hour(s) for
all roadways and major intersections in the study area. Volume/capacity
calculations shall be completed for all major intersections. All access
points shall be examined as to the necessity of installing traffic
signals. This evaluation shall compare the projected traffic to the
warrants for traffic signal installation.
F. Conclusions and Recommendations. Levels of service for all roadways
and intersections shall be listed. All roadways and/or intersections
showing a level of service below C shall be considered deficient,
and specific recommendations for the elimination of these problems
shall be listed. This listing of recommended improvements shall include,
but not be limited to, the following elements: internal circulation
design, site access location and design, external roadway and intersection
design and improvements, traffic signal installation and operation
including signal timing, and transit design improvements. All physical
roadway improvements shall be shown in sketches.
