[HISTORY: Adopted Orangetown Town Board 4-25-1960. Amendments noted where applicable.]
It is the purpose of these specifications to establish minimum acceptable standards of street construction for subdivisions in the Town of Orangetown including but not limited to width, design, drainage, construction of base and pavement, curbs and sidewalks, monuments and signs. Dedication of the right-of-way will not be accepted until the developer's professional engineer or qualified licensed land surveyor and the Town Superintendent of Highways shall have certified to the Town Board in writing that the construction of the street or streets has been completed in accordance with the approved plans and the specifications which follow.
In his written certification, as required above, the developer's professional engineer or qualified licensed land surveyor shall state clearly that he or his authorized representative has inspected all phases of the street construction and that all work has been completed in accordance with the approved plans and these specifications.
Plans of the proposed street shall be prepared by a qualified engineer or qualified land surveyor properly licensed by the State of New York. The plan shall clearly define the limits of the proposed right-of-way and shall include the location, widths, profiles and grades of proposed roadways, storm drainage including culverts and other drainage structures, and the location of easements and utilities. Plan shall first be submitted to the Town Superintendent of Highways and Town Engineer; and then to the County Superintendent of Highways, when any street drains toward or may otherwise affect a county highway; and then to the Town Planning Board for review and approval under the applicable subdivision regulations of the Town. Such plans so submitted shall not be altered or amended after having been approved by the Planning Board, unless amended plans are resubmitted and approved as above. However, the developer shall at his own expense provide additional storm drainage facilities as may be ordered by the Town Superintendent of Highways if, during the progress of the work, in the opinion of the Town Superintendent of Highways, the Town Engineer and/or the County Superintendent of Highways such additional structures or facilities are necessary to assure the durability of pavement, the future maintenance of right-of-way, or the welfare or safety of the public. If construction has not been started within one year from the date of final approval by the Town Planning Board, plans shall be resubmitted and approved as above.
A. 
Performance Bond. Prior to the start of construction of any improved street, the developer shall deposit with the Town Clerk a Performance Bond of acceptable surety or shall deposit with the Chief Fiscal Officer of the Town acceptable negotiable government bonds, cash or certified check drawn upon a national or state bank payable at sight to the Town Board, guaranteeing:
(1) 
That within two years the developer will complete all the construction within the right-of-way including roadway, shoulders, sidewalks, curbs, gutters, storm drainage, etc., and all utilities including hydrants and house connections for each lot in accordance with the approved plan and these specifications.
(2) 
That, upon certification by the developer's professional engineer or licensed land surveyor and by the Town Superintendent of Highways that the construction of the street has been completed in accordance with the approved plans and specifications, the developer will dedicate the completed street to the Town for use as a public highway free and clear of all liens and encumbrances. This guarantee of dedication shall apply to the owner of the property as well as the developer, where the two are not synonymous.
As guarantee for the performance of the above requirements, the developer shall deposit, as heretofore set forth, a surety bond, negotiable government bonds, cash or certified check, the minimum total amount of which shall be determined by applying to the quantities or dimensions shown on the approved plan the rates per unit as established by the schedule of rates attached hereto and forming a part hereof (Figure 1).

B. 
Maintenance Bond. Prior to acceptance by the Town of the dedication of the street as guaranteed by Paragraph (2) under Performance Bond, above, the developer shall deposit with the Town Clerk a Maintenance Bond of acceptable surety or shall deposit with the Chief Fiscal Officer of the Town acceptable negotiable government bonds, cash or certified check drawn upon a national or state bank payable at sight to the Town Board, guaranteeing that, for a period of two years from the date of acceptance of the dedication of the street by the Town, the developer will maintain the street to the standard of construction set by these specifications, normal wear and tear excepted. This shall be interpreted to mean that the developer will, at his own expense, repair and make good any defects or damage which may develop during this maintenance period as a result of faulty construction within the right-of-way or as a result of other construction by the developer off the right-of-way. During the maintenance period the Town shall be responsible for snow and ice control, street cleaning, cleaning of culverts and catch basins and other work of a similar routine nature, provided such work has in no way been caused by the developer's operations.
The amount of the maintenance bond shall be at least equal to 20% of the performance bond.
A. 
Also prior to acceptance by the Town of the dedication of the street, the developer shall file with the Town Clerk evidence that he has taken out for the same period of time as the Maintenance Bond an insurance policy in the amounts of $100,000/$300,000 for public liability, and $50,000 for property damage naming as the insured the Town Board and/or the Town Highway Department and/or the Town Superintendent of Highways.
B. 
The purpose of this requirement for insurance is to protect and defend the Town against any claims which may arise because of the operations of the developer or of possible defects in work performed by him.
C. 
Subsequent to the acceptance of the dedication of the street and after receipt of the Maintenance Bond and evidence of insurance by the Town, the Town Board shall release the Performance Bond.
The Town Planning Board shall determine and designate into which of the four following classifications each proposed subdivision street falls on the basis of one or more of the criteria hereinafter set forth:
A. 
Major or through streets.
B. 
Commercial or industrial streets.
C.

Major or through streets.
(1) 
The proposed street is the direct and logical continuation of a street that carried 500 or more cars during a twelve-hour period as shown on the latest traffic count.
(2) 
The proposed street creates a shorter and more convenient through-traffic artery so that it can be reasonably expected that traffic will be diverted from other major streets to such an extent that it will reach at least 500 cars in 12 hours, two years after opening.
(3) 
The proposed street is the principal collector for 300 or more homes in the neighborhood.
(4) 
The proposed street could logically be expected to become a major street because of future construction or other foreseeable circumstances.
B. 
Commercial and industrial streets.
(1) 
The proposed street is in an area zoned for commerce or industry.
(2) 
The proposed street is on or so close to the dividing line between a residential and a commercial or industrial area that it may reasonably be expected to carry a substantial volume of commercial or industrial traffic.
(3) 
The proposed street creates a shorter and more convenient route between a commercial or industrial area and a major traffic artery.
(4) 
The proposed street for any other reason may be expected to carry a substantial volume of commercial or industrial traffic.
C. 
Suburban-type streets.[1]
(1) 
The proposed street will serve subdivisions with lots under one acre in size.
(2) 
The proposed street shall not be or be reasonably expected to become a through, commercial or industrial street.
(3) 
The proposed street shall be a dead end, loop or other minor street within a development as distinguished from a principal collector as described in Paragraph (3) of Criteria for Major or Through Streets.

(1) 
The proposed street shall serve residential subdivisions with lots of a minimum size of one acre, where rezoning to small lot size is not designated in the zoning ordinance or contemplated in the Comprehensive Plan.
(2) 
The proposed street is not or cannot reasonably be expected to become a continuation or extension of a street of one of the three above-described classifications. Should such be the case, the proposed street shall take the classification of the street of which it is a continuation or extension.
(3) 
The proposed street does not or cannot reasonably be expected to carry a substantial volume of traffic.
A. 
The pages immediately following (Figures 2, 3, 4 and 5) show cross sections of each of the four classifications of subdivision streets. These give the required design, dimensions and construction details which are applicable to a particular classification.

Whenever, in the opinion of the Town Superintendent, ground conditions or other circumstances require it, larger or heavier materials, additional materials, reinforcing or other modifications and improvements in design and construction shall be made as directed by the Town Superintendent at any time prior to paving.
E. 
Location. Catch basins shall be constructed at all points of change of slope or alignment and at all junction points. At no time shall catch basins be spaced farther apart than 300 feet on slopes less than 3%; 250 feet on slopes from 3% to 6%; and 200 feet on slopes over 6% in steepness.
F. 
Excavation and concrete base. Hole for catch basin shall be excavated to a depth of 35 inches below the designated elevation of the invert of the effluent pipe. Crushed stone or run-of-bank gravel to a uniform depth of nine inches leveled and compacted over the entire area under the base shall be laid in the hole. On this stone or gravel shall be laid an eight inch-thick slab of 1-2-4-mix portland cement concrete. The slab shall extend four inches beyond the outside of the walls of the catch basin on every side. The slab shall be smooth and level. Through the center of the slab there shall be an opening for drainage one square foot in area which shall be protected and kept clean of concrete, mortar or other obstructing materials during construction.
G. 
Walls.

From five feet to a maximum depth of 10 feet below the finished surface, the walls shall be constructed of solid concrete catch-basin corner and stretcher blocks eight inches thick, similar or equal to those manufactured by the Multiplex Concrete Company, Inc.
(3) 
Below 10 feet from the finished surface, the catch-basin walls shall be 12 inches thick and shall be constructed of concrete block conforming to A.S.T.M. Designation C-139. All hollows in or between blocks in each course shall be completely filled with mortar before the succeeding course is laid so that finished wall is solid.
(4) 
All blocks forming the catch-basin walls shall be laid up with mortar composed of portland cement and mortar sand conforming to New York State Department of Public Works specifications in the proportion 1:2.
Inside dimensions of the catch basin shall remain constant from top to bottom and shall match the frame opening of the curb inlet to be used.
H. 
Installation of pipes.
(1) 
Concrete blocks around all pipes entering or leaving catch basin shall be cut to fit the contours of the pipes as closely as possible. Remaining interestices shall be solidly filled with mortar for the full thickness of the wall. Ends of all pipes shall be cut off flush with the inside surfaces of the catch basin walls.
(2) 
When the diameter of the effluent pipe is greater than that of an influent pipe, the elevation of the top of the influent pipe shall be no longer than the elevation of the top of the effluent pipe.
(3) 
When the diameter of the effluent pipe is the same as or smaller than that of an influent pipe, the elevation of the invert of the influent pipe shall be no lower than the elevation of the invert of the effluent pipe. In no case shall the top of any influent pipe be more than five feet above the invert of the effluent pipe.
I. 
Curb inlets.
(1) 
All catch basins shall be capped with curb inlets having a minimum frame opening of 30 inches by 48 inches. Curb inlets shall be similar or equal to either Campbell Foundry Company Pattern #2501 or Campbell Foundry Company Pattern #2541 (Stream Flow Grating), as designated by the Town Superintendent.
(2) 
Curb inlets shall be installed so that the top of the grating is two inches below the finished grade and the pavement shall be sloped toward the inlet as shown on the drawings which follow.
(3) 
Curb-front openings on all curb inlets shall have, centered in the opening, a solid horizontal bar to prevent the ingress of small children. This bar shall be part of the casting or solidly welded in place subsequent to manufacture.
J. 
Steps. Catch basins having a depth greater than 48 inches from the finished surface to the top of the concrete base shall be provided with steps. Steps shall be of wrought iron having a minimum diameter of 3/4 inch which shall be hot-bent to shape and hot-dipped galvanized after bending. They shall be solidly set in the masonry at the time of construction and shall extend all the way through the wall. The steps shall extend 4 1/2 inches inside the wall of the catch basin. The top step shall be not more than 18 inches below the finished surface and thence to the base steps shall be no more than 18 inches apart.
A. 
Before fine grading or construction of curbs and sidewalks is started, all storm and sanitary sewers and all utilities, including house connections and hydrants, shall have been installed and all fill and backfill shall have been thoroughly compacted to the satisfaction of the Town Superintendent of Highways.
B. 
Also before fine grading or construction of curbs and sidewalks is started, all heavy trucking for building or site construction purposes shall have been completed.
C. 
After completion of the rough grade and prior to the laying of the foundation course, the subgrade shall be shaped to line and grade and thoroughly 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 again rolled, this process to be continued until no depressions develop. The subgrade shall not be muddy or otherwise unsatisfactory when the foundation course is laid upon it.
D. 
Any soft or unstable portions of the subgrade which develop under the roller shall be completely excavated and removed from the right-of-way and shall be replaced with acceptable granular material and the area regraded and compacted as above.
E. 
Fine grade shall conform to the prescribed width of pavement and shall extend equidistant from the center line of the road right-of-way and shall conform to the typical cross section of the road pavement and to the approved line and grade.
After the fine grade and all curbs have been constructed to the satisfaction of the Town Superintendent of Highways, the developer shall furnish and place a foundation course of approved run-of-bank gravel, crusher-run stone or crusher-run gravel, to the depths as called for in these specifications. All materials acceptable for this course shall be hard, durable and sound and shall be well graded from coarse to fine, the maximum diameter of the large particles not exceeding 2/3 of the thickness of the compacted foundation course and 90% to 100% by weight of the particles shall be of such size as will pass through four inch square hole, not more than 70% by weight pass the #40-mesh sieve, and not more than 10% by weight pass the # 200-mesh sieve.
The materials shall be placed on the finished subgrade by means of mechanical spreaders and shall be thoroughly compacted by rolling with a self-propelled ten-ton roller. Water shall be added to the materials in such amounts as the Town Superintendent of Highways may consider necessary for proper compaction. After compaction, the course shall be true to grade and cross sections, and any depressions shall be eliminated by the use of additional granular materials, thoroughly rolled in place. In all cases, the foundation course must be so thoroughly compacted that it will not weave under the roller.
A. 
After the foundation course has been completed as the applicable sections of these specifications dictate and to the satisfaction of the Town Superintendent of Highways, the developer shall construct a base course of clean, dry, 1 1/2 inch crushed stone. The stone shall be evenly spread by means of an approved mechanical spreader in such quantities that after being compacted with a 10 ton roller, the thickness of the course shall be as called for in these specifications. Since it is imperative that this course conform accurately to the line, grade and cross section specified and as called for on the plans, the developer shall set up pins and lines or other controlled devices to attain the desired accuracy. Rolling shall begin at the sides or curbline and continue towards the center and shall continue until there is no movement of the course ahead of the roller.
B. 
After the stone base course has been completed and only between the dates of May 15th and October 31st, and when the stone is dry and clean, free of frost, and the atmospheric temperature is above 50° F., bituminous material shall be applied to the base course by means of a pressure distributor at a rate of not less than 1/2 gallon of bituminous material per square yard per inch of compacted thickness of stone, but in no event less than two gallons per square yard. Bituminous material shall be 100 to 120 penetration paving asphalt heated to a temperature of 275° F. to 350° F. and shall conform to N.Y.S.D.P.W. specifications of 1957 for Item 64P. Immediately after the application of the bitumonius material and while the liquid is still warm and in tacky condition, the surface of the base course shall be filled with clean, dry 5/8 inch stone, after which it shall be thoroughly rolled with a self-propelled ten-ton roller. Additional stone shall be applied and broomed about the surface during rolling until all voids in the surface of the stone base course are completely filled. Rolling shall continue until the cover stone is thoroughly keyed in the bitumen. Surplus stone shall then be removed from the surface.
Between November 1st and May 14th, with the prior written approval of the Town Superintendent of Highways, one of the two following alternate base courses may be substituted for the penetrated macadem base course specified above:
A. 
Stone- or sand-filled base course.
(1) 
Under this alternate the developer shall increase by 20% the compacted thickness of the 1 1/2 inch crushed stone base specified for penetrated macadam base course.
(2) 
After the stone base course is thoroughly compacted, stone screenings or washed concrete sand shall be uniformly spread upon the surface in sufficient quantities to fill the voids in the stone-base course and shall be swept into the voids by means of a gang drag-broom or by hand and then the base thoroughly rolled with a ten-ton roller. Additional stone screenings or sand shall be added and broomed about the surface until the voids in the stone base are filled to the satisfaction of the Town Superintendent of Highways. Water shall be sprayed on the surface if, in the opinion of the Town Superintendent of Highways, further consolidation or filling of the base can be effectuated. Care shall be exercised to insure that the voids in the stone base are completely filled, but the quantities of stone screenings or sand used and the operation of filling and rolling shall not be such as to cause floating of the coarse aggregate. All surplus filler shall be removed from the base course surface until the top surface of the coarse aggregates are exposed.
(3) 
If for any reason the subgrade or foundation course materials shall become churned up into or mixed with the stone base course, the developer shall remove such mixture and replace it with clean crushed stone thoroughly compacted and properly filled, as above.
B. 
Asphaltic concrete base course.
(1) 
Under this alternate, the developer shall substitute an asphaltic concrete base course equal in compacted thickness to that specified for penetrated macadam base course.
(2) 
After the foundation course has been completed to the satisfaction of the Town Superintendent of Highways, asphaltic concrete conforming to the current specifications of the N.Y.S.D.P.W. of 1957 for Item 45SX, Bottom Course Asphaltic Concrete, Type 1A, shall be uniformly spread by self-propelled mechanical spreader equipped with tamping bars and heating unit and in sufficient depth as to provide a finished compacted thickness after rolling equal to that specified for penetrated macadam base course. The base material in place shall be thoroughly rolled with a ten-ton roller.
(3) 
No trucking or construction traffic shall be permitted on any base course until the wearing surface has been constructed.
A. 
After the stone or asphaltic concrete base course has been completed to the satisfaction of the Town Superintendent of Highways, a two course bituminous concrete wearing course shall be constructed conforming to the N.Y.S.D.P.W. specifications of 1957 for Item 51M. Asphalt Concrete.
B. 
After the base course has been thoroughly cured and cleaned of all foreign material, a bituminous concrete binder course shall be uniformly spread by a self-propelled mechanical spreader with tamping bars and heating unit in sufficient depth as to provide a finished compacted thickness after rolling of not less than one and 1 1/2 inch. The course in place shall be thoroughly rolled with a ten-ton roller.
C. 
After the binder course has been completed and thoroughly cleaned of foreign material, and a tack coat of asphalt emulsion applied to the surface at the rate of 1/10 gallon to 1/20 gallon per square yard, in the event that the binder course has been subject to traffic for an extended period of time, a final wearing course of fine bituminous concrete shall be uniformly spread by a self-propelled mechanical spreader equipped with tamping bars and heating unit and in sufficient depth as to provide a finished compacted thickness after rolling of not less than one inch. The fine wearing course in place shall be thoroughly compacted with a two or three wheel tandem roller weighing approximately 10 tons.
D. 
Extreme care shall be exercised in the placing of bituminous concrete to insure 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.
A. 
Six inch portland cement concrete curbs shall be constructed on both sides of the street as shown on Figures 2, 3, 4 or 5 and to the dimensions and specifications shown on Figure 8.

The approved porous material to be held as a foundation course of the concrete sidewalk as shown in Sidewalk Details in Figures 2, 3 and 4 shall be washed gravel, crushed stone or hard steam cinders approved by the Town Engineer or Superintendent of Highways.
[Added 6-11-1962]
Developer shall construct all street intersections in accordance with Figure 12, except in the case of a new street intersecting an existing narrow road, when it shall be modified as shown on Figure 13.
Developer shall furnish and install a four way street name sign at every street intersection made by the streets he constructs. Signs and posts shall conform to the standards established by the Town Board.
A. 
Monuments shall be set on all right-of-way lines of streets at all street intersections, angle points, points of curve and subdivision corners. There shall be a clear foresight and backsight to adjacent monuments on the right-of-way line or lines on which a monument is set.
B. 
Monuments shall be 36 inches long, five inches square at the top tapering to six inches square at the bottom and shall have centered in the top a 3/8 inch or 1/2 inch drill hole, a 3/8 inch or 1/2 inch steel rod slightly protruding, or some other permanent and satisfactory center mark. Monuments shall be of cut granite free from imperfections or of concrete and similar or equal to those supplied by Bergen Building Block, Inc., Ridgefield Park, New Jersey.
C. 
Monuments shall not be set before final grading has been completed nor shall they be set while frost is in the ground. They shall be set so that the top is flush with the finished grade. They shall be so set and tamped as to prevent settlement or shifting.
D. 
Developer's engineer and/or licensed land surveyor shall certify that the location of all monuments is accurate before acceptance of the street by the Town Board.
Where surface water must be led through other than right-of-way gutters and storm drains or existing stream channels, drainage easements having a minimum width of 15 feet shall be provided in the approved plans. A greater width than 15 feet shall be provided where called for by other provisions of these specifications.
A. 
With the approval of the Town Superintendent of Highways and Town Engineer, open ditches may be used in lieu of storm drainpipes when the grade of the land traversed is flat or when it is desirable to drain and dry up the surrounding area.
B. 
Open ditches shall be constructed in accordance with Figure 14 of these specifications, but in no case shall the grade of an open ditch exceed 3%. Riprap, when called for, shall consist of field stone or rough, unhewn quarry stones as nearly cubical in form as is practicable, placed upon a slope not steeper than 1:2 and so laid that the weight of the large stones is carried by the soil and not by the stone adjacent. All stones shall weigh between 50 - 150 pounds each and at least 60% of them shall weigh more than 100 pounds each.
C. 
The largest stones shall be placed first, roughly arranged and in close contact. The spaces between the larger stones shall be filled with spalls of suitable size.

Roof and cellar drains shall in no case be allowed to flow onto the street right-of-way. With the approval of the Town Superintendent of Highways and Town Engineer in writing, these drains may be piped to the street stormwater pipe drain to which they shall be connected on top only. Such drains must be installed prior to the start of fine grading of the streets.
Wherever a temporary or permanent dead-end is allowed on a subdivision street, a turn-around shall be constructed. This turn-around shall take the form of a tee or a circle as required by the Town Planning Board and shall be constructed as shown on Figures 17 and 18. The temporary type of construction shall be used only when authorized by the Town Planning Board because of the foreseeable future extension of the street. The circular-shaped turn-around shall be completely paved with no center island.
A. 
Streets shall be so designed that finished tangent grades will not be less than 0.7% or more than 10%.
B. 
Every change in grade shall be effected with a vertical curve of sufficient length to insure adequate stopping sight distance and to provide for smooth transition. These vertical curves shall be designed in accordance with the graph shown on Figure 19 of these specifications which is taken from New York State standards for 30 M.P.H. speeds.
Final decision as to the interpretation of any part of these street specifications shall rest with the Town Superintendent of Highways.
In the event that any part or parts of these Street Specifications for Subdivisions, or of any ordinance or regulations which may govern or otherwise affect them, is for any reason modified or invalidated, the other portions of said specifications not affected thereby shall remain in full force and effect.
