[HISTORY: Adopted by the Town Board of the Town of Wallkill 5-24-1973; amended in its entirety 6-26-1997 by L.L. No. 5-1997. Subsequent amendments noted where applicable.]
GENERAL REFERENCES
Building construction — See Ch. 82.
Streets and sidewalks — See Ch. 205.
Subdivision of land — See Ch. 209.
Zoning — See Ch. 249.
Sewer specifications — See Ch. A252.
It is the purpose of these specifications to establish minimum acceptable standards of street construction for subdivisions or other new public roads to be constructed in the Town of Wallkill, including, but not limited to, width, design, drainage, the construction of base and pavement, curbs and sidewalks, monuments and signs. Dedication of the right-of-way will not be accepted until the Town Engineer or the Commissioner of Public Works shall have advised 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, and recommended acceptance of dedication.
In the written certification, as required above, the Town Engineer and/or the Commissioner of Public Works 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.
A plan of the proposed street shall be prepared by a qualified engineer 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. The plan shall be submitted to the Commissioner of Public Works and the Town Engineer, and then to the County Superintendent of Highways when any street drains toward or may otherwise affect a county highway, and then shall be returned 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 Commissioner of Public Works if, during the progress of the work, in the opinion of the Commissioner of Public Works, the Town Engineer and/or the County Superintendent of Highways, such additional structures or facilities are necessary to assure the durability of the pavement, the future maintenance of the right-of-way or the welfare or safety of the public, except that the Town Planning Board may vary the requirements of such order where there are practical difficulties or unnecessary hardships in the way of carrying out the strict letter of such order, unless such variance conflicts with the provisions of a town or county official drainage map, in which event the official map shall prevail. If construction has not been started within two years from the date of final approval by the Town Planning Board, plans shall be resubmitted and approved as above.
A. 
Prior to the start of construction of any improved street, the developer shall deposit with the Town Clerk a letter of credit or a performance bond of acceptable surety or shall deposit with the chief fiscal officer of the town acceptable negotiable government bonds, cash or a 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 the roadway, shoulders, sidewalks, curbs, gutters, storm drainage, etc., and all utilities, including hydrants and house connections for each lot, in accordance with the approved plans and these specifications.
(2) 
That, upon certification by the Town Engineer or by the Commissioner of Public Works, 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 guaranty of dedication shall apply to the owner of the property as well as the developer where the two are not synonymous.
B. 
As a surety for the performance of the above requirements, the developer shall deposit as heretofore set forth a letter of credit, surety bond, negotiable government bonds, cash or certified check, the minimum total amount of which shall be calculated by the developer's engineer and submitted to the Town Engineer and Commissioner of Public Works for review and approval. The amount of surety shall not be less than 100% of the public improvement costs, and estimates of these costs shall be calculated utilizing current costs for municipal construction and prevailing wage rates.
(1) 
If a building permit is requested to be issued prior to completion of public improvements, the surety shall be in the form of cash or certified check.
C. 
Prior to being deposited with the Town Clerk or chief fiscal officer as described in Subsection A above, surety instruments shall be submitted to the attorney for the town for review and approval. When deposited with the Town Clerk or chief fiscal officer, surety instruments shall be accompanied by a written acknowledgment by the attorney for the town that the instrument is acceptable.
D. 
No surety instruments shall be allowed to expire until the work is complete, the improvements have been dedicated to the town and the Town Board has passed a resolution allowing expiration of the surety. Each surety instrument shall include language acknowledging that the instrument shall remain in effect until the above conditions are met.
[Amended 3-23-2006 by L.L. No. 3-2006]
The owner/developer is responsible for the payment of all inspection and as-built drawing fees for work required in § 249-42 C(2). Initially, an inspection fee of a percentage to be set by resolution of the Town Board, of the amount of the construction costs shall be paid to the town prior to the time that the Chairman of the Planning Board signs the final plat and the start of any site improvement work. The inspection fee will be held in escrow by the town (project inspection escrow fund) and will be used to pay any and all town engineering, legal and staff expenses associated with the inspection, as-built drawing preparation and dedication of the improvements. If during the construction of the improvements the project inspection escrow fund is reduced to a level that the Commissioner of Public Works or the Town Engineer deems is insufficient to complete the required inspections, the owner/developer shall, within 30 days notification by the Commissioner of Public Works, furnish such additional inspection fees to the town. If said additional inspection fees are not furnished to the town within said thirty-day period, the owner/developer must cease any and all construction of site improvements until the additional inspection fees are paid. The project inspection escrow fund shall be held in an interest bearing account, and any balance of the account, including interest, shall be returned to the owner/developer after completion and dedication of the improvements.
A. 
Prior to acceptance by the town of the dedication of the street as guaranteed by § A251-4A(2) above, the developer shall deposit with the Town Clerk a letter of credit or a maintenance bond of acceptable surety or shall deposit with the chief fiscal officer of the town acceptable negotiable government bonds, cash or a certified check drawn upon a national or state bank payable at sight to the Town Board, guaranteeing that, for a period of one year from the date of acceptance of the dedication of the street by the town, the developer will maintain that 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 that such work has in no way been caused by the developer's operations.
B. 
The amount of the maintenance bond shall be at least equal to 10% of the original amount of the performance bond.
C. 
Subsequent to the acceptance of the dedication of the street and after receipt of the maintenance bond, the Town Board may release all or part of the performance bond.
A. 
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:
(1) 
Major or through street.
(2) 
Commercial or industrial street.
(3) 
Suburban-type street.
(4) 
Rural-type street.
B. 
Final plans shall be drawn to show, and the developer shall construct each street in accordance with the particular specification for its designated classification, as also hereinafter set forth, as well as in accordance with the specifications and details common to all classifications.
C. 
Fire lanes or fire apparatus access roads shall be constructed generally equivalent to the standards established for rural roads.
A. 
A proposed street shall be designated a major or through street when any of the following conditions exist as determined by the Town Planning Board at the recommendation of the Town Engineer and/or the Commissioner of Public Works:
(1) 
The proposed street is the direct and logical continuation of a street that carries 500 or more cars during a twelve-hour period as shown by the latest traffic count.

(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. 
A proposed street shall be designated a commercial or industrial street when any of the following conditions exist:
(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. 
A proposed street shall be designated a suburban-type street (NOTE: This classification is intended to cover the majority of subdivision streets) when any of the following conditions exist:
(1) 
The proposed street will serve subdivisions with lots under one acre in size.
(2) 
The proposed street shall reasonably not be expected to become a through, commercial or industrial street.

The proposed street shall serve residential subdivisions with lots of a minimum size of one acre where rezoning to a smaller lot size is not designated in the Zoning Ordinance.[1] or contemplated in the Comprehensive Plan.
[1]
Editor's Note: See Ch. 249, Zoning.
(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.
Figures 1, 2, 3, 4 and 5[1] 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. Following is a comparative summary sheet which lists the major items of construction for all types of streets and may be useful as a checklist of requirements. Thereafter are set forth the general and more detailed specifications for design and construction applicable to all streets. The developer shall design and construct streets which shall conform to both the specific and the general specifications.

A. 
Design. The storm drainage system shall be designed in accordance with the criteria established by the Town of Wallkill in these specifications. The minimum grade of any drainage pipe shall be 1%. Any deviations from the criteria herein shall be specifically noted and approved by the town during the Planning Board review and approval process.
B. 
Excavation, laying and backfilling.
(1) 
The width of the trench in which the pipe is placed shall be sufficient to permit thorough tamping of the backfill under the haunches and around the pipe and shall not exceed the pipe's outside diameter plus 24 inches when measured at the top of the pipe. Where rock in either boulder or ledge formation is encountered, it shall be removed below grade and replaced with suitable materials in such a manner as to provide a crushed stone bedding of 3/4 inch having a thickness under the pipe of not less than eight inches. In all other areas, the pipe shall be placed on a crushed stone bedding of 3/4 inch having a thickness of not less than six inches. In no case shall the top of any drainage pipe be less than 18 inches below the finished grade of the pavement. Where soft, spongy or other unstable soil is encountered at the pipe subgrade established, all such unstable soil under the pipe and for a width of one diameter on each side of the pipe shall be removed and replaced up to the pipe subgrade elevation with 3/4 inch clean crushed stone or other acceptable material. In all cases, the crushed stone pipe bed of 3/4 inch shall be thoroughly compacted and shall provide a firm foundation for the pipe.
[Amended 5-26-2016 by L.L. No. 11-2016]
(2) 
Pipe shall be laid to true line and grade on the prepared bed of the trench. All connections for making field joints in corrugated metal pipe shall consist of corrugated metal bands so constructed as to lap on equal portions of each of the culvert sections to be connected.

(3) 
Immediately after pipes have been laid, backfilling shall commence. The material surrounding the pipe, the pipe embedment zone, shall be crushed stone of 3/4 inch, carefully placed and thoroughly compacted in such a manner that the line and grade of the pipe are not disturbed. Backfill material shall be placed evenly and carefully on both sides and over the pipe in six-inch lifts, and each lift shall be thoroughly compacted until one foot of crushed stone cover exists over the pipe.
(4) 
Where the drainage pipe is installed outside the paved limits of right-of-way, the trench above the pipe embedment zone may be backfilled with material excavated from the trench, if approved by the Commissioner of Public Works. This backfill shall contain no stones larger than eight inches in any dimension. The backfill shall be placed in eight-inch lifts and thoroughly compacted. This backfill will be carried to an elevation 12 inches below finished grade. Eleven inches of NYSDOT Item 4 shall then be placed on top of the trench, covered by one inch of clean topsoil and seed.
[Amended 5-26-2016 by L.L. No. 11-2016]
(5) 
Where the pipe is installed in any paved area subject to vehicular traffic, the entire trench above the embedment zone shall be backfilled to grade with NYSDOT Item 4, placed in eight-inch lifts and thoroughly compacted.
(a) 
Where NYSDOT Item 4 is referred to in these specifications and is proposed below pavement or other hard surfaces, the material shall be compacted to 95% modified proctor.

A. 
The 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 Commissioner of Public Works.
B. 
The developer shall submit proposed street names to the Commissioner of Public Works for approval.
C. 
The developer shall also furnish and install all necessary regulatory and warning signs as determined by the Town Engineer and/or Commissioner of Public Works in accordance with the standards established in the Manual of Uniform Traffic Control Devices (MUTCD).
A. 
Monuments shall be set on all right-of-way lines of streets and at all street intersections, angle points, points of curvature 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 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.
C. 
A licensed land surveyor retained by the owner/developer shall certify that the location of all monuments is accurate and provide an as-built right-of-way map and a metes and bounds description of the as-built right-of-way to the Commissioner of Public Works before the acceptance of dedication of the street by the Town Board.
D. 
Monuments shall be solid concrete, 36 inches long, four inches square at the top, tapering to five inches square at the bottom. A No. 3 zinc-coated rebar shall be embedded in the concrete. The rebar shall protrude 1/2 inch to 3/4 inch from the top of the concrete. Monuments with the embedded rebar and a two-inch square brass plate set in the top shall be considered equal.
E. 
Monuments of aluminum pipe may be provided if approved by the Commissioner of Public Works. Aluminum monuments shall be constructed of thirty-six-inch-long, two-and-three-eighths-inch aluminum pipe, with a three-and-one-fourth-inch diameter aluminum magnetic cap riveted to the top.
Where surface water must be lead through other than right-of-way gutters and storm drains or existing stream channels, drainage easements having a minimum width of 30 feet and a temporary width of 50 feet for working access shall be provided in the approved plans. A greater width shall be provided where called for by other provisions of these specifications or where necessary to conduct future maintenance.
A. 
With the approval of the Commissioner of Public Works and Town Engineer, open ditches may be used in lieu of storm drain pipes 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[1] of these specifications, but in no case shall the grade of an open ditch exceed 10%. Riprap, when called for, shall consist of field stone or rough, unhewn quarry stones as nearly cubical in form as is practicable. A weed barrier fabric shall be placed under the riprap, and then the stones shall be placed upon a cross-section slope not steeper than 1V to 2H and so laid that the weight of the large stones is carried by the soil and not by the stone adjacent. All stones shall be sized as necessary to ensure their permanent stability.

Editor's Note: Copies of Figures 1 through 17 are at the end of this chapter.
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.
D. 
Whenever a drainage pipe enters an open ditch, the bottom and sides of the ditch shall be riprapped for a distance of at least 15 feet beyond the end of the pipe.
A. 
Roof and cellar drains shall in no case be allowed to flow into the street right-of-way. These drains shall be daylighted well back from the street so that water flows from them do not enter upon the public right-of-way.
B. 
With the approval of the Commissioner of Public Works or the Town Engineer, in writing, these drains may be piped directly to an adjacent catch basin. Such drains must be installed prior to the start of fine grading of the streets, and any such piping within the right-of-way shall be permanently maintained by the owner of the property serviced by the piping installed.
Wherever a temporary or permanent dead end is allowed on a subdivision street, a turnaround shall be constructed. This turnaround 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 16 and 17.[1] The temporary type of construction shall be used only under special conditions when authorized by the Town Planning Board because of the foreseeable future extension of the street. The circular-shaped turnaround shall be completely paved with no center island.

Editor's Note: Copies of Figures 1 through 17 are at the end of this chapter.
Streets shall be so designed that finished tangent grades will not be less than 1% nor more than 10%. Every change in grade shall be effected with a vertical curve of sufficient length to ensure adequate stopping sight distance and to provide for smooth transition. These vertical curves shall be designed in accordance with New York State standards for speeds of 30 miles per hour unless the street is to be posted for a speed limit in excess of the current town-wide limit.
The final decision as to the interpretation of any part of these street specifications shall rest with the Commissioner of Public Works. He shall have the authority to modify the requirements of these specifications when, in his opinion, conditions make it impracticable to follow the strict letter of these specifications or when conditions make it unnecessary to do so.
