A. 
Clearing and grubbing.
(1) 
All trees, perishable matter, boulders, structures, fences and debris of whatever nature shall be cleared from the full width of the roadway section, including both cut and fill slopes, except that trees located not closer than three feet from the edge of pavement may remain subject to the approval of the Superintendent. All roots and stumps within the limits of the road section shall be grubbed and excavated, except that no grubbing will be required where the finished roadway surface will be six feet or more above the original ground surface where foundation soil is satisfactory. Where trees are cleared and grubbing is not required, the trunks shall be cut off flush to the ground if possible, and in any instance not more than six inches above the ground.
(2) 
Specially designated trees or other objects which have been designated to remain within the right-of-way shall be protected and preserved by whatever means necessary to ensure that no damage will be incurred during the construction.
(3) 
At intersections and on curves additional clearing may be necessary to provide adequate visibility.
(4) 
This work shall all be as approved by the Superintendent.
B. 
Topsoil. Topsoil shall be stripped from all surfaces of the roadway area which will be disturbed by the cut or fill operation. Topsoil so stripped shall be stockpiled on the site and shall be reserved for roadway landscaping unless approval for other usage has been granted by the Superintendent.
C. 
Subgrade.
(1) 
The subgrade shall be brought to the required grade by excavation or filling.
(2) 
The subgrade material in cuts or fills shall be excavated or placed as the case may be so that the compacted and shaped subgrade surface is at least 19 inches below the finished grade of the proposed pavement surface.
(3) 
All objectionable materials, including soft clays, muck, peat and organic material lying below the proposed subgrade elevation within the paved area of the roadway shall be excavated to good bottom and replaced by crushed stone, gravel or other approved granular material.
(4) 
Excavated material, if suitable, may be used in forming embankments.
(5) 
Rock, when encountered, shall be removed to the slopes and lines shown on the Standard Details contained herein or as directed by the Superintendent.[1] Excavated rock shall be replaced with suitable material in a manner that will provide a compacted earth layer to a minimum thickness of 12 inches below the subgrade surface and at least eight inches below the bottom of pipes, conduits, cables, drainage structures or manholes. Blasting shall be performed only by licensed, competent personnel. Blasts shall be properly covered and safety measures observed, all in accordance with the Safety Code of the State of New York governing storage and use of explosives, § 764, Subdivision 3, of the General Business Law, as amended, and all other pertinent laws, ordinances or codes. Insurance coverage shall be as required, and proof of adequate insurance shall be presented to the Superintendent prior to commencement of any blasting work.
[Amended 6-16-1998]

Editor's Note: The Standard Details are included at the end of this chapter.
(6) 
The subgrade shall be constructed by rolling, shaping and such rerolling and reshaping and removal and replacement of unsuitable material causing soft spots as required to provide a uniform, stable, dense surface properly crowned to drain water laterally to the roadway edges.
(7) 
Where an embankment is required, the fill shall be spread in layers not to exceed six inches in depth, loose, bladed to an even surface free from clods and compacted by rolling with an approved power roller. Boulders or rock fill shall not be deposited within two feet of the finished subgrade elevation. Areas not accessible to the power roller, such as in the vicinity of catch basins, manholes, culverts, underground utilities and the like, shall be adequately compacted by approved mechanical hand tampers. Filling, compacting and shaping operations shall continue alternately until the roadway section, free of all soft spots, both cut and fill, conforms in all respects to the lines and grades shown on the approved construction plans and to the standards contained herein.
(8) 
Crushed stone or gravel may be substituted for earth fills if specifically approved by the Superintendent.
(9) 
Smooth steel wheel rollers, when approved, shall have a minimum weight of 10 tons. Rollers of other types shall be as approved by the Superintendent.
(10) 
Approval of the subgrade elevations must be obtained prior to the installation of any underground utility.
D. 
Base course. The base course shall be constructed to the lines, grades and typical cross section as shown on the approved plat and construction plan and to the Standard Details contained herein.[2] The thickness of the base course after compaction shall be 12 inches. All material shall be approved by the Superintendent.
(1) 
Materials. All materials used in the construction of the base course shall consist of selected sand, gravel and soil binder, free from injurious quantities of flaky materials. The particles shall be well graded from coarse to fine and of such size as will pass a two-inch-square sieve, 30% to 65% by weight shall pass the one-fourth-inch-square sieve and not more than 10% by weight shall pass a No. 200 sieve. Particles passing a No. 40 mesh sieve shall have a plasticity index of zero.
(2) 
Construction. No segregation of large or fine particles will be allowed, but the material as spread shall be well graded with no pockets of fine material, and the thickness of any layer shall have a maximum depth of six inches after compaction. Water shall be added in such amounts as the Superintendent may consider necessary to secure satisfactory compaction. When the moisture content of the layer is within the limits for proper compaction, the entire surface shall be rolled with a smooth wheel roller having a minimum weight of 10 tons. After compaction, the course shall be tested with a straight edge 16 feet in length, and any depression over 1/4 inch shall be eliminated by the use of the same material and the surface rerolled. In all cases, this course must be so thoroughly compacted that it will not weave under the roller.
[2]
Editor's Note: The Standard Details are included at the end of this chapter.
E. 
Surface course. The penetration macadam surface course shall be composed of broken stone and bituminous material applied by the penetration method. It shall be constructed on the prepared base course in conformity with the lines, grades, compacted thickness and typical cross section shown on the plans. The thickness of the surface course after compaction shall be five inches. All materials shall be approved by the Superintendent.
(1) 
Materials.
(a) 
The coarse aggregate and key stone shall be crushed stone. The crushed stone shall consist of hard, durable particles or fragments of stone, free from flat, elongated, soft or disintegrated pieces, dirt or other objectionable matter. Crushed stone for coarse aggregate and key stone shall meet the requirements for grading given in Table I.

(b) 
Bituminous materials used for this course shall meet the requirements of New York State Department of Public Works. Specifications of January 2, 1972, for asphalt emulsions, Grade MS-2h.
(c) 
No bituminous material shall be applied at any time without the approval of the Superintendent.
(2) 
Construction.
(a) 
Upon a prepared subgrade, coarse aggregate conforming to Gradation 3 shall be spread in the required amount by approved mechanical spreaders to a uniform depth and true to line and grade.
(b) 
No stone with a dust coating will be permitted for use in this course. If any stone spread for this course becomes wet or dirty, it must be allowed to dry to the full depth of the course, and dirty stone removed and replaced with clean stone before the spreading of bituminous material proceeds. The coarse aggregate shall be dry rolled with a self-propelling roller weighing approximately 10 tons, until compacted and keyed. Rolling shall progress gradually from the sides to the center parallel to the center line of the road and shall continue until the aggregate does not creep or wave ahead of the roller.
(c) 
After the coarse aggregate has been thoroughly compacted, bituminous material, heated to a temperature between 75° F. and 170° F., shall be evenly spread over the surface by the use of an approved pressure distributor, operating under a pressure of 50 pounds per square inch or more as the Superintendent may direct. The quantity of bituminous material used in the first application shall be 2 1/2 gallons per square yard, or as directed by the Superintendent.
(d) 
Immediately following the application of bituminous material, key aggregate conforming to Gradation 1 shall be spread evenly over the surface until the voids are filled. Rolling of the surface shall start immediately after spreading while the bituminous material is still warm and shall continue until the course of stone is thoroughly compacted and its surface is true and even to the established grade.
(e) 
After this portion of the work shall have been completed, all loose stones shall be swept from the surface.
(f) 
After the penetration course has been completed and thoroughly cleaned of foreign material, a tack coat of asphaltic emulsion shall be applied to the surface at the rate of 1/10 gallons to 1/20 gallons per square yard. The tack coat shall be required in all cases unless specific approval for omitting this requirement has been granted by the Superintendent. A final wearing course of fine bituminous concrete shall be uniformly spread by a self-propelling mechanical spreader equipped with tamper bars and heating unit in sufficient depth as to provide a finished compacted thickness after rolling of not less than two inches. The fine wearing course in place shall be thoroughly compacted with a two- or three-wheel tandem roller weighing approximately 10 tons.
(g) 
Extreme care shall be exercised in the placing of bituminous concrete to ensure that all longitudinal joints shall be lapped in the placing of adjoining strips and that all lateral joints are trimmed before continuing with the placing of additional materials on that strip.
(h) 
The aforementioned top course bituminous concrete wearing course shall be constructed conforming to the New York State Department of Public Works Specifications of January 2, 1973, or as amended, for hot-mix asphalt concrete pavement, Section 403.
F. 
Curbs. Curbs shall be constructed along the edge of any new street pavement in accordance with the dimensions and details shown in the Standard Details.[3]
[3]
Editor's Note: The Standard Details are included at the end of this chapter.
G. 
Slopes. Cut or fill sections beyond the sidewalk area shall not be steeper than one unit vertical to 1 1/2 units horizontal except in rock. The Superintendent may require a decrease in the amount of slope to whatever extent necessary to maintain the stability of the bank under the particular soil conditions. All earth slopes and areas that have been disturbed in any way due to construction of the road shall be covered with a minimum four inches of topsoil and suitably seeded or planted with perennial rye grass to prevent erosion. The Superintendent may require the removal of or adjustment of slopes adjacent to intersections in order to assure adequate sight distance at the intersection. Excess excavated material may be used to flatten slopes as approved by the Superintendent.
Storm drainage shall be designed in accordance with the following standards:
A. 
Pipe.
(1) 
Sufficient pipe shall be installed within the subdivision to carry existing watercourses and to drain the proposed roads and roads which may reasonably be expected to be constructed at some future date on adjoining property which normally drains across the area of the proposed subdivision. If, in the judgment of the Superintendent, there will be no substantial danger from soil erosion or danger to the public health and safety, the Superintendent may permit the discharge of stormwater and established watercourses in open ditches across proposed lots of 40,000 square feet or larger. All pipe shall be of such diameter, not less than 15 inches, as will be sufficient to properly carry stormwater expected to enter the pipe from the proposed subdivision and from other properties, when developed, which normally drain across the area of the proposed subdivision.
(2) 
Storm sewers shall be designed to safely carry loads resulting from storms of the maximum intensity which can be expected to occur on an average of once in 10 years without being surcharged. Culverts crossing under existing or proposed public streets shall be designed to accommodate flows resulting from storms of the maximum intensity which can be expected to occur on an average of once in 25 years without causing flooding of the roadway or adjacent properties.
B. 
Method of design. The following criteria are intended to act as a guide for engineers designing storm drainage facilities for installation in the Town of Southeast. They are intended to indicate the minimum acceptable stormwater runoff quantities. Special conditions may warrant the use of more stringent design criteria.
(1) 
Stormwater flows may be computed by use of the Rational Method or by use of the methods described in the U.S. Soil Conservation Service publications SCS-TP-149 and Technical Release No. 55.
(a) 
Where the Rational Method formula is used:
Q
=
ACR
Where:
Q
=
Quantity of flow, in cubic feet per second.
A
=
Contributing drainage area, in acres.
C
=
Runoff coefficient.
R
=
Rainfall intensity, in inches per hour.
[1] 
Rainfall intensities shall be computed as follows:
Storm sewers, R = 170 divided by (t + 23)
Culverts, R = 230 divided by (t + 30) (25-year storm frequency only)
Where "t" is the time of concentration, in minutes.
