The arrangement, character, extent, width, grade
and location of all streets shall conform to the General Community
Plan and shall be considered in their relation to existing and planned
streets, to topographic conditions and to public convenience and safety
and in their appropriate relation to the proposed uses of the land
to be served by such streets and shall conform to the following design
standards in a manner acceptable to the Planning Commission:
A.
Where not shown on the General Community Plan, the
arrangement of streets in a subdivision shall either:
B.
Minor streets shall be so laid out that their use
by through traffic will be discouraged.
C.
Where a subdivision abuts or contains an existing
or proposed arterial street, railroad right-of-way or rail crossings,
access thereto shall be limited to a minimum number of intersections
as is practicable, and such major access intersections with arterial
streets and/or rail crossings shall be determined with due regard
for sight distance, distance between intersections, approach grades
and requirements for future grade separations.
D.
Marginal access streets paralleling such limited access
arterial streets shall be required, in such cases where practicable,
reversing the frontage of residential properties with a screen planting
contained in a nonaccess reservation strip along the rear of and between
the property line and the arterial street right-of-way. Such reserve
strips shall be prohibited except where their control is definitely
placed with the municipality.
E.
Street jogs with center-line offsets of less than
125 feet shall be avoided.
F.
A tangent at least 100 feet long shall be introduced
between curves on arterial and collector streets.
G.
When connecting street lines deflect from each other
more than 10°, they shall be connected with a curve with a radius
adequate to ensure sight distance.
H.
Streets shall be laid out to intersect as nearly as
possible at right angles, and no street shall intersect any other
street at less than 60°.
I.
Alleys shall be permitted only in cases where necessary.
J.
Street right-of-way widths shall be not less than
as follows:
|

K.
Dead-end streets designed to be so permanently shall
not be longer than 600 feet and shall be provided with a turnaround
having an outside road diameter of at least 80 feet and a property
line diameter of at least 100 feet.
L.
No street grade shall be less than 1/2 of 1% or more
than 10%, unless topographic conditions make a steeper grade necessary.
Easements across lots centered on rear or side
lot lines or where necessary for utilities, watercourses, drainageways,
channels or streams shall be not less than 10 feet wide.
A.
The length, width and shape of blocks shall be determined
with due regard to:
B.
Block lengths shall not exceed 1,800 feet.
C.
In cases where the block length exceeds 600 feet and/or
where deemed essential to provide pedestrian circulation to schools,
playgrounds, shopping centers and other community facilities, an easement
for a crosswalk shall be provided of not less than 10 feet wide.
A.
The lot size, width, depth, shape and orientation
and the minimum building setback lines shall be appropriate for the
location of the subdivision and for the type of development and use
contemplated.
C.
Corner lots for residential use shall have an extra
width of at least 10% of the above-required width to permit appropriate
building setback from and orientation to both streets.
D.
The subdividing of the land shall be such as to provide,
by means of a public street, each lot with satisfactory access.
A.
In reviewing subdivision plans, the Commission will
consider the adequacy of existing or proposed community facilities
to serve the additional dwellings proposed by the subdivision.
B.
Where a proposed park, playground, school or other
public use shown on the Official Map is located in whole or in part
in a subdivision, the Commission may require the reservation of such
area as may be deemed reasonable. Where said area is not dedicated,
it shall be reserved for acquisition by the municipality for a period
of not more than one year.
C.
Areas provided or reserved for such community facilities
shall be adequate to provide for building sites, landscaping and off-street
parking as appropriate to the use proposed.
D.
The layout of the proposed subdivision shall be in
general conformity with the features or developments proposed in the
Master Plan of the Borough of Danville.
E.
Streets which are obviously in alignment with existing
streets shall generally bear the name of the existing street. Street
names applied to completely new streets shall not duplicate or closely
approximate, phonetically, the names of existing streets in the Borough.
F.
The subdivider shall plan the layout to preserve the
natural features of the site.
A.
When a subdivision is reasonably accessible to a municipal
sewer system, the subdivider shall provide the subdivision with a
complete sanitary sewer system to be connected to the municipal sanitary
sewer system.
B.
When no municipal sewer system is available or one
is not reasonably accessible to the subdivision, the subdivider shall
provide the subdivision with a complete sanitary sewer system which
shall connect with a sanitary sewer outlet approved by the Pennsylvania
Department of Environmental Protection; except that when such approved
outlet is not available, one of the following methods of sewerage
shall be used:
(1)
A complete sanitary sewerage system to convey the
sewage to a treatment plant, to be provided by the subdivider in accordance
with minimum requirements of the Pennsylvania Department of Environmental
Protection, with adequate provisions for the maintenance of such plant.
(2)
Private sewage disposal systems on individual lots,
consisting of septic tanks and tile absorption fields or other approved
sewerage disposal systems, when laid out in accordance with minimum
standards approved by the Pennsylvania Department of Environmental
Protection.
(3)
Cesspools. Under the terms of this chapter, no new
installation of cesspools for the disposal of sewage shall be permitted.
C.
The plans for the installation of a sanitary sewerage
system shall be prepared by the subdivider and approved by the Engineer
and the Pennsylvania Department of Environmental Protection. The Engineer
shall inspect the sewer line before it is covered over. Upon the completion
of the sanitary sewer installation, one copy each of the plans for
such system, as built, shall be filed with the Commission and the
municipality.
D.
Storm sewers shall not be connected with sanitary
sewers.
[Amended 12-9-2002 by Ord. No. 447[1]]
A.
Where not prohibited by this chapter or any other laws or ordinances, land located in flood-prone areas may be platted for development with the provision that the developer construct all buildings and structures to preclude flood damage in accordance with this chapter; Chapter 102, Construction Codes, Uniform, of the Danville Borough Code; and other laws and ordinances regulating such development.
B.
If the Borough determines that only a part of a proposed
plat can be safely developed, it shall limit development to that part
and shall require that development proceed consistent with this determination.
C.
When a developer does not intend to develop the plat
himself and the Borough determines that additional controls are required
to ensure safe development, it may require that developer to impose
appropriate deed restrictions on the land. Such deed restrictions
shall be inserted in every deed and noted on every recorded plat.
D.
All subdivision proposals and development proposals
containing at least 50 lots or at least five acres, whichever is the
lesser, in flood hazard areas where base flood elevation data are
not available, shall be supported by hydrologic and hydraulic engineering
analyses that determine base flood elevations and floodway information.
The analyses shall be prepared by a licensed professional engineer
in a format required by FEMA for a Conditional Letter of Map Revision
or Letter of Map Revision. Submittal requirements and processing fees
shall be the responsibility of the applicant.
