(2) Paving design is based on overall soil conditions in the Borough.
The Borough Council may require additional paving, base or subbase
materials where soil types are inferior, wet or otherwise unsuitable
as indicated by the Soil Survey of Chester and Delaware Counties,
Pennsylvania, prepared by the U.S. Soil Conservation Service or where,
in the opinion of the Borough, such conditions exist.
(3) Alternate paving sections may be approved by the Borough Council
and the Borough Engineer, as long as the proposed alternative meets
the structural strength achieved with the above pavement specification.
B. Subgrade.
(1) The area within the limits of the proposed road surface shall be
shaped to conform to the line, grade and cross-section of the proposed
road.
(2) All unsuitable subgrade material shall be removed.
(3) All wet or swampy areas shall be permanently drained and stabilized,
subject to the approval of the Borough Engineer.
(4) Fills, within the roadway, shall be made with suitable materials
approved by the Borough Engineer and thoroughly compacted for full
width in uniform layers of not more than eight inches thick. No more
than two eight-inch layers of fill shall be laid or placed between
inspections by the Borough Engineer.
(5) The subgrade shall be thoroughly compacted by rolling with a minimum
ten-ton three-wheel roller. Equivalent vibratory, sheep's foot
or rubber-tired rollers may be used upon approval of the Borough Engineer.
Subgrade shall be compacted tight and dry, to 95% compaction at optimum
moisture, according to ASTM D1557, and shall not be soft and spongy
under the roller. Compaction of the subgrade shall extend the full
width of the cartway, including the width to be occupied by shoulders.
(6) In fill areas over three feet thick, compaction tests are required
in each eight-inch layer at one-hundred-fifty-foot intervals. The
tests must be performed by a certified testing laboratory and results
submitted to the Borough Engineer. All compaction must be 95% compaction
at optimum moisture. Any layer not coming up to standard will be removed
or re-rolled until suitable compaction is obtained.
C. Paving.
(1) Paving and base thickness and materials shall be as specified in Subsection
A of this section.
(2) The subbase course, where required, shall be installed and compacted
in accordance with Pennsylvania Department of Transportation specifications
and shall extend a distance of eight inches for base course and wearing
course and 18 inches for crushed aggregate base course on all street
ledges beyond the paving line when curbs are not to be installed.
(3) Bituminous base, binder and surface courses shall be laid to the
specified thickness measured, after compaction. All bituminous courses
shall be laid with a mechanical bituminous paver in accordance with
specifications of the Pennsylvania Department of Transportation Specifications,
Publication 408, and latest edition thereof.
(4) Delivery slips for all material deliveries shall be furnished to
the Borough Engineer.
(5) Failure to adhere to the above specifications shall give the Borough
Council cause to refuse to accept streets for dedication.
(6) All wearing courses shall be sealed to the concrete curb with a solid
one-foot-wide Class BM-1 bituminous gutter seal.
(7) Paving shall not be placed when surface temperatures are below 45°
F.
D. Grading and shoulders.
(1) Roadways shall be graded for the full width of the right-of-way on
each side, unless modified by the Borough Council to permit less grading
to avoid disturbance of significant trees, historic structures, or
other significant natural or cultural resources. Shoulders or berm
areas, including planting strips behind curbs, shall be graded with
a minimum slope of 1/2 inch per foot and a maximum slope of one inch
per foot. Beyond the limits of this grading, banks shall be sloped
to prevent erosion, but this slope shall conform to details included
in Appendix A-2.
(2) Seeding. All unpaved areas between the street line and the curb or
shoulders (as the case may be) shall be covered with not less than
six inches of topsoil, fertilized, seeded, and mulched in a manner
and with materials approved by the Borough Council.
E. Underdrains may be required by the Borough Council or Borough Engineer
to mitigate wet road conditions.
F. Utility trench construction (storm sewer, wastewater lines, water
main, gas main etc.) within existing streets shall be backfilled with
2A modified stone placed and compacted in eight-inch lifts. The trench
shall be paved with Superpave Asphalt Mixture Design, HMA Base Course,
PG 64-22, 0.3 to 3 M ESALS, 25 mm mix (four inches compacted depth),
Superpave Asphalt Mixture Design, HMA Binder Course, PG 64-22, 0.3
to 3 M ESALS, 19 mm mix (two inches compacted depth), and the entire
roadway shall be paved with a full width overlayment (edge of road
to edge of road) of Superpave Asphalt Mixture Design, HMA Wearing
Course, PG 64-22, 0.3 to 3 M ESALS, 9.5 mm mix, SRL-L (1 1/2
inches compacted depth). Utility trenches within proposed streets
shall be backfilled with clean, dry, select material and compacted
in eight-inch lifts to not less than 100% of the determined dry weight
density of the backfill material. Trenches within easements shall
be backfilled with clean, dry, select material and compacted in twelve-inch
lifts to not less than 100% of the determined dry weight density of
the backfill material as set forth in ASTM D 1557 and PennDOT Form
408, latest revised.
G. During construction of roads, the contractor shall provide maintenance
and protection of traffic meeting Pennsylvania Department of Transportation
standards.

All subdivisions or land developments shall provide for adequate stormwater management in compliance with the requirements set forth in the Media Borough Stormwater Management Ordinance, Chapter
251, as applicable.
All subdivisions or land developments shall comply with the
requirements set forth in the Media Borough Zoning Ordinance, as applicable.
All proposed earth disturbances shall comply with the following
standards related to grading and earthwork:
A. Natural and/or existing slopes exceeding one vertical unit to four
horizontal units shall be benched or continuously stepped into competent
materials prior to placing all classes of fill. Cut slopes shall not
exceed one vertical unit to three horizontal units, except that cut
slopes up to one vertical unit to two horizontal units may be permitted
where the Borough is satisfied that such steeper cut slopes will reduce
negative impacts of grading disturbance overall and that adequate
erosion control is provided.
B. Fills toeing out on natural slopes steeper than one vertical unit
to three horizontal units shall not be made unless approved by the
Borough after receipt of a report, deemed acceptable by the Borough
Engineer, by a soils engineer certifying that he/she has investigated
the property and made soil tests and that in his/her opinion such
steeper slopes will safely support the proposed fill.
C. Fill areas shall be properly prepared prior to the placement of any
new material. The area should be closely examined to determine whether
excessive wetness, springs, or other seepage of water can be observed.
If such conditions exist, drainage must be provided before placement
of fill is undertaken. Under no circumstances shall fill be placed
upon frozen ground or ground underlain by tree stumps, branches, or
other vegetative material subject to rot and decomposition.
D. Fill should begin at the lowest section of the area. Fill should
be spread in six-inch layers prior to compaction.
E. Each layer of fill should be inspected prior to compaction. All roots,
vegetation or debris should be removed. Stones larger than six inches
in diameter should be removed or broken.
F. Each layer of compacted fill should be tested to determine its dry
density as per ASTM D1556, including latest revisions. The density
of each layer should be not less than 95% of maximum dry density as
determined by ASTM D1557. The moisture content of the compacted layer
should be not more than 4% less nor 2% greater than the optimum moisture
content as determined by ASTM D1557.
G. The top or bottom edge of filled or cut slopes shall be at least
three feet from property or right-of-way lines of streets in order
to permit the normal rounding of the edge without encroaching on the
abutting property.
H. When required, adequate provisions shall be made for dust control
measures as are deemed acceptable by the Borough.
I. All graded surfaces shall be seeded, sodded and/or planted or otherwise
protected from erosion as soon as practicable and shall be watered,
tended and maintained until growth is well established at the time
of completion and final inspection.
