F. 
Guarantee.
(1) 
A certified check, bond, or other security acceptable to the Town in the amount agreed upon with the Town Highway Superintendent as to the value of the work to be performed by the developer shall be deposited with the Town Clerk of the Town of Cazenovia prior to construction of the road and before the road is offered for dedication to insure completion as to time and specifications. This deposit shall be returned at the time of satisfactory completion of the work as indicated by the Town Highway Superintendent.
(2) 
A certified check, bond, or other security acceptable to the Town in the amount of 5% of the roadway construction cost will be offered as a retainer for a period of one year after final acceptance of the road by the Town Highway Superintendent as a guarantee against any repairs within that period. The Town Board will not accept the dedication of any new road or street or development in any year from November 15 to April 30 of the next succeeding year.
A. 
General.
(1) 
The developer shall remove all rock, earth and other material required by the plans for the full width of the roadway. He shall dispose of this material as required.
(2) 
Earth embankments shall be constructed to established lines and grades for the full width of the roadway at the locations shown on the plans. Embankment material shall be natural soil free from excessive moisture, frost, stumps, trees, roots, sod, muck, marl, vegetation or other unsuitable materials. Embankment material shall be obtained from approved borrow pits and shall be well graded from fine to coarse with not more than 15% passing a two-hundred-mesh sieve.
(3) 
Where embankments are to be placed under water, only acceptable granular material shall be used. All materials shall be suitable for compaction in layers not exceeding eight inches in thickness and shall remain stable when wet.
B. 
Stripping.
(1) 
Prior to the commencement of excavation or fill, stripping shall be conducted to remove all topsoil, roots, organic matter, rubbish or other debris for the full width of the pavement and adjacent disturbed land.
(2) 
Usable topsoil from stripping may be stockpiled for future use at approved locations outside the limits of the road right-of-way.
C. 
Materials to be used.
(1) 
If there is not sufficient excavated material of a suitable quality at the site to complete the embankment, subgrades, and backfilling to the required lines and grade, the developer shall borrow the necessary additional materials. The source and acceptability of the borrow material shall be subject to the approval of the Town Highway Superintendent or the designated engineer.
(2) 
The developer shall request approval of proposed borrow areas at least five days before taking any material from such areas. All test pits, explorations, and laboratory tests required by the Town Highway Superintendent or Engineer to evaluate the acceptability of borrow shall be done by the contractor at his own expense.
D. 
Placing.
(1) 
In general, embankment materials shall be placed in horizontal layers not exceeding eight inches in thickness measured prior to compaction and shall be thoroughly compacted. Stones, if any, shall not exceed four inches in greatest dimension and shall be well distributed through the mass.
(2) 
Each layer of embankment material shall be thoroughly tamped or rolled to the required degree of compaction by sheepsfoot or pneumatic rollers, mechanical tampers or vibrators. Successive layers shall not be placed until the layer under construction has been thoroughly compacted.
(3) 
Trucks or other heavy equipment shall not be operated over pipelines until a minimum of 18 inches of backfill above the crown of the pipe has been placed and properly compacted.
E. 
Compaction control.
(1) 
Embankment shall have a minimum dry density of 95% of the maximum dry weight density in pounds per cubic foot as determined by the AASHTO standard density test or the proctor compaction test.
(2) 
All laboratory tests required by the Town Highway Superintendent or the Engineer shall be done by an approved testing laboratory at the developer's expense.
(3) 
When the test results indicate that insufficient compaction has been obtained in any layer, the developer shall take such action as the Town Highway Superintendent or the Engineer may direct to modify or alter the moisture content of the soil, to provide additional compaction or otherwise to increase the in-place soil density.
The developer shall prepare the subgrade to receive the pavement and concrete gutters in conformity with the lines and grades as shown on the plans. Before the subbase course material is placed upon the subgrade, it shall be shaped to line and grade and compacted with an approved self-propelled roller weighing not less than 10 tons. All hollows and depressions which develop under rolling shall be filled with acceptable granular material and shall again be rolled. Granular materials used to fill depressions shall consist of approved hard, durable particles 100% of which shall pass a one-half-inch sieve and not more than 5% of which shall pass a No. 200 sieve. This process of shaping and roll and filling shall be repeated until no depressions develop. The subgrade shall not be muddy or otherwise unsatisfactory when the subbase material is placed upon it. If soft spots develop during the rolling, the material shall be removed and replaced with acceptable granular material as above.
The granular subbase course shall be constructed in accordance with the plan and complying with NYSDOT Specifications dated January 3, 1978, Section 304 or as amended.
