shall be completed by the developer in accordance with the requirements
of the Township and this article.
The developer shall place permanent reference
monuments in all subdivisions as required herein. Any monuments or
markers that are removed during construction and/or grading of the
site shall be placed in original locations by a registered engineer
or surveyor at the expense of the person removing them.
A. Monuments.
(1) Monuments shall be made of precast concrete with a
minimum diameter of six inches and a minimum length of 36 inches,
and shall be set flush with the finished grade. A brass pin shall
be set in the top of each monument and scored or marked to indicate
the exact point of crossing of the intersecting lines.

At the intersection of all lines forming angles
in the boundary of the subdivision or land development; and
(b)
At the intersection of all street lines.

(1) Markers shall consist of magnetic metal pipes or bars
at least 36 inches long and not less than 1/2 inch in diameter, and
shall be set flush with the finished grade. They shall be scored to
indicate the exact point of crossing of intersecting lines.
(2) Markers shall be set permanently at all lot corners.
All streets, except those approved as private
drives, shall be irrevocably dedicated, in writing, by the developer
to the Township of Lawrence immediately on completion and acceptance
of construction. Such streets shall be graded to the elevations and
dimensions shown on the plans, profiles, and cross sections submitted
by the developer for final plan review, and as approved by the Township
Supervisors.
A. Local street construction. All Township streets shown
on the approved final plan shall be constructed in accordance with
the specifications for street construction of the state and Lawrence
Township.
(1) Preparation of subgrade. The subgrade shall be formed
by shaping the graded roadway surface to the approved profile. The
surface shall be brought to a firm, thoroughly compacted condition
for the width of the base course by rolling with a power roller. Any
soft or unsuitable material shall be removed and replaced with suitable
material.
(2) Installation of cartway. Installation of the cartway
by the developer shall comply with PennDOT 408 Construction Specifications
unless otherwise approved by the Board of Township Supervisors.
(a)
CP-2 surfacing.
[1]
Course aggregate. The first course shall conform
to Pennsylvania Department of Transportation standards for No. 4 aggregate
and shall be graded gravel, crushed gravel, crushed stone, or crushed
slag, meeting the approval of the Township. This shall be compacted
to a four-inch layer.
[2]
Top course. The top course shall consist of
granulated slag or graded gravel equivalent to Pennsylvania Department
of Transportation standards for No. 2-A aggregate, spread and compacted
into a four-inch layer. The depth after final compaction shall be
as indicated on the approved plans and the surface shall be brought
to a crown.
[3]
Surface course. This is a standard CP-2 surface
course with initial primer and a No. 2-B stone dragged and rolled
as applied; then three successive layers of No. 1-B stone, and tar
applied to build up the appropriate tar-and-chip surface.
(b)
Bituminous surfacing.
[1]
Base course. The base course shall consist of
a layer of hot-mixed, bituminous, concrete base course BCBC installed
according to PennDOT Specifications, 408. This shall be compacted
by an approved power roller to a three-inch layer.
[2]
Surface course. This surface course shall consist
of a layer of one of the following: 1D-2, FB-1, or FB-2 mixed and
installed according to PennDOT specifications, Form 408. This shall
be compacted to a one-inch layer. If the base course has deteriorated
prior to the installation of surfacing, it shall be brought to a suitable
condition prior to laying the surface course.
B. Collector and major street construction. Specifications
for the construction of collector and major streets shall be established
by the Board of Township Supervisors after consultation with the Pennsylvania
Department of Transportation.
If water is to be provided by means other than
by private wells owned and maintained by the individual owners of
lots within the subdivision, applicants shall present evidence to
the Township Supervisors, as the case may be, that the subdivision
is to be supplied by a certified public utility, a cooperative association
of lot owners, or by a municipal corporation, authority or utility.
A copy of a certificate of public convenience from the Pennsylvania
Public Utility Commission or an application for such certificate,
a cooperative agreement or a commitment or agreement to serve the
area in question, whichever is appropriate, shall be acceptable evidence.
Where deemed necessary by the Township Supervisors,
its Planning Commission, and the Clearfield County Conservation District,
the developer shall provide the subdivision with an adequate stormwater
drainage system. This system shall be consistent with the Pennsylvania
Stormwater Management Act and any Township regulations. In the absence of such regulations,
a stormwater drainage system shall be reviewed by the Clearfield County
Conservation District, and shall meet the following objectives:
A. Assure that the maximum rate of stormwater runoff
is no greater during and after development than prior to development;
and
B. Manage the quantity, velocity, and direction of stormwater
runoff in a manner which adequately protects health and property.
Street name signs shall be installed in the
Township of Lawrence in all major subdivisions containing a new street
and shall be installed according to standards established by the Township.
Proposed street names shall be reviewed by the local post office and
the Township Planning Commission.
