general requirements and all applicable Borough specifications. In
the absence of a governing applicable specification, the applicable
standards and requirements of the Pennsylvania Department of Transportation
shall govern.
A. Grading. All details of the cross-section, crowns, curb, pavement,
subgrade, subdrains, and roadside ditches, shall be graded and/or
constructed to conform to the designated cross-section as provided
by the Borough Engineer and approved by Borough Council.
B. Subgrade.
(1) The subgrade shall be graded and shaped to conform to the approved
plans with a minimum width of the pavement plus two feet. It shall
be thoroughly compacted and stabilized to the satisfaction of the

be removed and replaced with a suitable granular material as directed
by the Borough. Unacceptable materials are all materials with a C.B.R.
(California bearing ratio) value of 21.5 or less and is not of proper
quality to develop the required stability and provide for adequate
drainage. These are primarily soft plastic clays or silty material
where the clay or silt content is over 50%. The subgrade shall be
inspected and approved by the Borough Engineer prior to placement
of the subbase.
(2) The prepared subgrade shall be protected by the contractor to prevent,
undue rutting from trucks or other equipment, and if such damage does
occur, the subgrade shall be reshaped and compacted prior to placing
the subbase material.
C. Subdrains under pavement.

Borough Engineer. Blind or side drains at intervals, as required by
the Borough Engineer, shall be installed leading into the main subdrain.
The required interval for side drains shall be related to ground water
conditions, but in no case shall this interval be greater than 100
feet. If conditions require, six inches corrugated metal perforated
pipe shall be installed in the side drains. Blind or side drains shall
extend to the curblines.
(2) In parts of the Borough where the natural ground is a well drained
gravel, subdrain requirements may be relaxed. Deviation from the subdrain
requirements will be considered upon written request and each case
considered separately.
D. Subbase.
(1) All utilities, including water, gas, sanitary sewers, storm sewers,
buried conduits of any kind or any other structures or lines shall
be placed prior to the laying of the subbase.
(2) The subbase shall be made of approved gravel or stone and shall have
a minimum thickness at any point of six inches when compacted. Additional
depth of the subbase may be required.
(3) The material and method of construction used shall conform to PADOT
Publication 408, Section 350.
(4) The subbase shall be thoroughly compacted and shaped to the proper
grade and cross-section to receive the base course.
(5) The finished subbase shall be inspected and approved by the Borough
Engineer before placing of the base course.
E. Base. The base shall be constructed in accordance with Borough and
PADOT specifications.
F. Pavement. The pavement shall be constructed in accordance with Borough
and PADOT specifications. The base shall have been in place for a
minimum of one year before placement of a wearing surface.
All new or rebuilt streets shall be constructed with concrete
curbs in accordance with accepted standards and in accordance with
Borough specifications.
Every lot in a subdivision shall be capable of being served
by gas, electrical and telephone utilities and the necessary easements
shall be provided. Utility distribution lines shall be installed within
street rights-of-way or within properly designated easements. To the
fullest extent possible, underground utility lines should be located
in easements along the rear property lines, but when local conditions
require installation in street rights-of-way, lines should not be
installed beneath existing or proposed paved areas and in any case
shall be installed prior to the placement of any paving.
The developer shall be responsible for making the necessary
arrangements with the Borough and the appropriate public utility company
to install streetlighting fixtures. However, whether or not streetlights

utility easements for future streetlighting installations upon consultation
with the public utility company involved and the Borough Council.
