Department of Public Works — See Ch. 34.
Subdivision of land — See Ch. 137.
Zoning — See Ch. 164.
It is the purpose of these specifications to establish minimum acceptable standards of street construction for subdivisions which have been established by the towns of Orange County to conform to legal requirements in the State of New York, which requirements and standards must be met and paid for by the person or firm proposing that the Town take over such road as a Town road. Those specifications include but are not limited to width, design, drainage, construction of base and pavement, curbs and monuments. Dedication of the right-of-way will not be accepted until the developer's professional engineer and the Town Commissioner of Public Works or Town Engineer shall have certified to the Town Board, in writing, that the construction of the street or road has been completed in accordance with the approved plans and specifications that follow and that the total right-of-way area has been cleared of all debris and all construction has been completed in a workmanlike manner. When new road rights-of-way are offered to the Town for dedication, two copies of the final plan and deed description of the right-of-way shall be submitted to the County Superintendent of Highways for approval pursuant to § 170 of the Highway Law.
In his written certification, as required above, the developer's professional engineer 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 specifications.
[Amended 6-23-1988 by L.L. No. 1-1988; 3-24-2005 by L.L. No. 1-2005]
A. 
A plan of the proposed street shall be prepared by a qualified professional engineer licensed by the State of New York. The plan shall clearly define the limits of the proposed right-of-way by metes and bounds and shall include the location, widths, profiles and grades of the proposed roadway, storm drainage, including culverts and other drainage structures, and the location of all easements and utilities. The plans shall also indicate owner of property and name of developer if other than owner. One copy each of the plans shall be submitted to the Town Commissioner of Public Works and Town Engineer at the time of application to make such road a Town road, and to the County Superintendent of Highways when said proposed street drains toward, intersects or may otherwise affect a county highway. It will then be submitted to the Town Planning Board for review and approval under the applicable subdivision regulations of the Town. Such roadway must not be subject to any right or easement in others which will in any way interfere with its use as a road at all times. Such roadway must be granted to the Town by a full covenant and warranty deed containing the correct metes and bounds description as shown on the approved map, which deed must be in such form as may be required to entitle the same to be recorded in the office of the County Clerk of Orange County. A policy of title insurance or other assurance of title satisfactory to the Town Attorney shall be provided to the Town when the road offered is accepted. All expenses incidental to the dedication and acceptance of any road shall be borne by the applicant. The provisions of § A168-3 shall apply to private roads and common driveways, where applicable, as directed by the Planning Board or the Town Engineer.
B. 
Permanent and temporary easements must be furnished in said deed granting to the Town the right to maintain all outlets of culverts and drainage structures for surface water or natural stream drainage which will run from such roadway over private property to a point where a natural watercourse exists and to which such outlet and easement will carry such water. A minimum width of easement of 20 feet shall be required for the maintenance of said easements.
C. 
The proposed roadway must be constructed to conform to the minimum requirements and standards set forth below. The minimum width to be cleared shall include all trees, rock formations, buildings, walls and any such things that would endanger those using the roadway. The removal of such obstructions shall be borne by the person or firm proposing such road.
D. 
A stormwater and pollution prevention plan (SWPPP) shall be prepared for all roadways and/or sites in which roadways shall be constructed. The SWPPP shall be prepared in accordance with the requirements of the New York State Department of Environmental Conservation's most recent State Pollutant Discharge Elimination System (SPDES) general permit for stormwater discharges from construction activity and the Town Engineer. A copy of the SWPPP shall be submitted to the Town Engineer for approval prior to the issuance of a building permit.
E. 
Upon completion of the project and prior to acceptance of the roadway by the Town, a complete set of as-built drawings shall be submitted to the Town Engineer for approval. The as-built drawings shall show all easements, rights-of-way, monuments, structures (both above ground and below ground), utilities, sidewalks, driveways and other pertinent features.
[Amended 3-24-2005 by L.L. No. 1-2005]
Plans submitted shall not be altered or amended after having been approved by the Town Commissioner of Public Works and the Planning Board unless amended plans are resubmitted and approved. However, the developer, at his own expense, shall provide additional storm drainage facilities or utilities as may be ordered by the Town Commissioner of Public Works if, during the course of construction, 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 prevent any need for future installations of utilities or culverts within the pavement area, to assure the durability of pavement, future maintenance of rights-of-way or welfare and safety of the public, 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 of said road has not been started within one year from date of final approval by the Town Planning Board, plans shall be resubmitted and approved as above.
[Amended 6-23-1988 by L.L. No. 1-1988; 3-24-2005 by L.L. No. 1-2005]
A. 
Performance bonds.
(1) 
Prior to the start of construction of any street, the developer shall deposit with the Town Clerk a performance bond of acceptable surety, with no expiration date, 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:
(a) 
Within two years the developer will complete all public improvements and all the construction within the right-of-way, including roadway, shoulders, curbs, if any, gutters, storm drainage, etc., and all utilities, including hydrants and house connections for each lot, as well as all stormwater management and pollution control measures in accordance with the approved plans and these specifications; and that all claims for labor and materials in connection with said construction will have been paid in full prior to offering said road for dedication to the Town.
(b) 
Upon certification by the developer's professional engineer and by the Town Commissioner of Public Works and Town Engineer 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 guaranty of dedication shall apply to the owner of the property as well as the developer where the two are not synonymous.
(2) 
As guaranty for the above requirements, the developer shall deposit as hereto 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 plans the rates per unit as established by the schedule of rates hereto set forth and forming a part hereof.

B. 
Maintenance bonds.
(1) 
Prior to acceptance by the Town of the dedication of the street as guaranteed by Subsection A(1)(b) above, the developer 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 one year 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 outside 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 similar routine nature, provided that such work has in no way been caused by the developer's operations.
(2) 
The amount of the maintenance bond shall be at least equal to 10% of the original amount of the performance bond.
(3) 
Subsequent to the dedication of the street and after receipt of the maintenance bond, the Town Board shall release the performance bond.
[Amended 6-23-1988 by L.L. No. 1-1988; 3-24-2005 by L.L. No. 1-2005]
A. 
The developer shall design and construct streets which shall conform to the specifications.
B. 
When fill exceeds three feet, the subgrade and foundation course shall be in place a minimum of three months to allow complete settlement before pavement is laid, unless fill is laid in twelve-inch increments and compacted to the specified density and to the satisfaction of the Town Engineer. Field density tests shall be conducted and submitted to the Town, whether by the Town Engineer or when contractually required by the developer's Engineer. The test data shall clearly include the results of the tests, plus the location of each test.
[Amended 3-24-2005 by L.L. No. 1-2005]
A. 
The developer shall establish and clearly mark on site the limits of road rights-of-way and easements with concrete monuments, and the center line and grades of the finished road pavement and the location and elevations of drainage structures as shown on the approved plans with construction stakes. Such construction stakes shall be maintained at the developer's expense until the construction of road pavement, drainage structures, curbs, sidewalks and shoulders has been completed, inspected and approved by the Town Commissioner of Public Works and the Town Engineer.
B. 
Permanent concrete monuments shall be set on right-of-way lines of streets at all intersections, angle points, point of curvature and beginning and end of streets. There shall be a clear view of adjacent monuments on the right-of-way line. All monuments shall exist on completion of the construction of the streets. The permanent markers shall be made of concrete or granite with minimum dimensions of 30 inches long, four-inch square top and six-inch square bottom with a one-half-inch drilled hole in the top. If a monument should be located in a rock ledge, the surface shall be stripped and a one-half-inch steel rod drilled into the ledge. Monuments shall protrude three inches above the final graded surface.
C. 
The developer's licensed surveyor shall certify that the location of all monuments is accurate before acceptance of the street by the Town Board.
[Amended 6-23-1988 by L.L. No. 1-1988; 3-24-2005 by L.L. No. 1-2005]
Where surface water from streets must lead through other than gutters and storm drains or existing stream channels outside the right-of-way, permanent drainage easements having a minimum width of 20 feet shall be provided to a point where a natural watercourse exists. In some cases this may include easements over property outside the boundaries of the subdivision involved. Natural stream or ditch channels shall have a minimum fifteen-foot-wide permanent easement and be shown on the proposed plans of subdivision. All permanent easement lines shall be monumented as a right-of-way.
[Amended 3-24-2005 by L.L. No. 1-2005]
A. 
The developer shall clear the entire area within the limits of:
(1) 
The road right-of-way.
(2) 
Stream channels and ditches.
(3) 
Easement areas (as determined by the Town Commissioner of Public Works).
B. 
All stumps, roots, walls and buildings shall be excavated and removed from the above areas.
[Amended 6-23-1988 by L.L. No. 1-1988; 3-24-2005 by L.L. No. 1-2005]
A. 
The developer shall complete the shaping of the road right-of-way, streams and ditches and easement areas to the line and grade as shown on the approved plans and as otherwise may be directed by the Town Commissioner of Public Works. In the construction of the roadway, all topsoil, loam, rocks and organic material shall be removed until a firm, unyielding subgrade is established. All fills shall be made with acceptable material as approved by the Town Commissioner of Public Works. Such fills shall be made in loose layers of not more than 12 inches thick and properly compacted with a vibratory roller or equivalent to a minimum of 90% of the maximum dry density as determined by the modified proctor tests (ASTMD1557).
B. 
The subgrade shall be shaped to line and grade with no depressions. The subgrade shall be stable in all respects to the satisfaction of the Town Commissioner of Public Works and Town Engineer before the foundation course is laid. No large stones, rock ledges or organic material shall protrude into the foundation course. The subgrade shall be approved to be suitable for supporting overlying pavement section by a licensed professional engineer familiar with pavement design and construction.
C. 
Also, before the foundation course is laid, all storm and sanitary sewers and all utilities, including house connections for existing and future homes, and hydrants shall have been installed to the satisfaction of the Commissioner of Public Works and Town Engineer. All utilities shall be marked by placement of warning marker tape, directly above the utility, 18 inches to 24 inches below grade, when completing the work. All slopes and sidewalk areas shall be graded before the foundation course is laid, and all loose and exposed stones will be removed.
D. 
Design, testing and certification.
(1) 
Criteria. All pavement sections should be designed based on natural undisturbed (cut) or embankment fill subgrades having a modulus of subgrade reaction (Mr) equal to or greater than 5,000 pounds per square inch. If, in the design engineer's opinion, the natural or embankment fill subgrade material cannot, within a reasonable factor of safety, provide the minimum support noted above, the subgrade shall be modified in accordance with Subsection D(3) below.
(2) 
Testing.
(a) 
Proposed subgrades along planned roadway alignments shall be tested in the field by the use of test pits and/or soil borings, at a spacing no greater than every 200 feet, excavated to a depth suitable for determining the existing conditions at the planned roadway subgrade elevation. The minimum depth shall be as required to penetrate through any existing fill or unsuitable materials and reach firm natural soil, but no less than eight feet below the existing ground surface. Representative samples shall be taken from these field tests for laboratory testing of the soil characteristics.
(b) 
Tests shall also be performed at prospective on-site source areas for embankment fill materials. Samples shall be taken from a minimum of two locations within each source area for laboratory testing.
(c) 
Laboratory testing shall be performed on soil samples collected during the field investigation to determine design characteristics of the soils encountered. Laboratory testing shall include, but not be limited to, determination of particle size distributions, Atterburg limits, maximum dry densities (by the Modified Proctor Method) and other tests determined to be necessary by the design engineer.
(3) 
Design.
(a) 
If, upon completion of testing, the design engineer determines that the proposed roadway subgrade meets the criteria given in Subsection D(1) above, the standard pavement design provided below shall be utilized. If upon completion of testing, the design engineer determines that the proposed roadway subgrade does not meet the criteria given in Subsection D(1) above, the existing subgrade shall be remediated to the extent necessary to meet the specified criteria.
(b) 
Subgrade remediation may consist of removal of the unsuitable soils and replacement with embankment fill materials meeting the requirements of Appendix F of these specifications.[1] Alternatively, the design engineer may specify a soil improvement technique to achieve the criteria given in Subsection D(1) above. Soil improvement techniques may include, but shall not be limited to, the use of: geotextiles for soil separation or stabilization, geogrid reinforcement beneath and within embankment fills, or other methods of subgrade stabilization. The design engineer shall provide adequate written documentation (including calculations) detailing the design of the modifications to the Town Engineer for approval prior to commencement of construction.
[1]
Editor's Note: Appendix F is included at the end of this chapter.
(c) 
Wherever testing indicates that the foundation fill is to be placed over soil containing more than 25% of the material, by weight, passing the No. 200 sieve, the foundation course shall be separated from the underlying soils by a separation fabric. The separation fabric may be either woven or nonwoven and shall have both trapezoidal tear and puncture strengths of at least 50 pounds. The design engineer shall specify a geotextile with an apparent opening size that is determined to be suitable for separating the subgrade from the foundation course.
(4) 
Construction.
(a) 
Upon removal of all topsoil and unsuitable materials, as described in Subsection A of this section, all natural roadway subgrades shall be proofrolled under the supervision of a licensed professional geotechnical engineer or his or her designated subordinate(s). All natural subgrades shall be approved by the licensed engineer prior to the placement of embankment fill or the foundation course. If, during the course of subgrade inspections, the inspecting engineer determines that the subgrade is unsuitable for supporting the embankment fill or foundation course, the subgrade shall be modified in accordance with Subsection D above.
(b) 
All embankment fill and subgrade fill shall be tested for compliance with the specified material characteristics as well as degree of compaction. All fill materials shall be compacted to the consistency defined in Subsection A of this section. Compaction testing shall be in-place nuclear method and/or the in-place sand cone method, as specified by ASTM. Field density tests shall be performed at no less than one test lift per 100 feet of roadway alignment.
(5) 
Certification. At the conclusion of construction, a professional engineer licensed in the State of New York shall certify that all roadway subgrades were observed to be suitable for supporting embankment fills and pavement sections, and that fills have been placed and compacted in accordance with these and the project specifications. This certification shall be submitted to the Commissioner of Public Works and the Town Engineer, whether the testing is performed by the Town Engineer or, where contractually required, performed by the developer's engineer.
[Amended 6-23-1988 by L.L. No. 1-1988; 3-24-2005 by L.L. No. 1-2005]
A. 
The foundation course shall consist of select granular subgrade (§ A168-23A) (NYSDOT Item 203.20) to a minimum thickness of six inches, with a top of 12 inches of subbase material (§ A168-23A) (NYSDOT Item 304.12) as approved by the Commissioner of Public Works. It shall contain stones no larger than four inches in thickness and be well-graded from coarse to fine. The material shall be placed on the prepared subgrade in two layers, and each layer shall be thoroughly compacted by rolling with a vibratory roller or other equivalent compaction equipment to a minimum of 95% of the maximum dry density, as determined by the Modified Proctor Test (ASTMD1557). After compaction, the foundation course shall be fine graded to an elevation allowing for the six inches of wearing course and approved by the Commissioner of Public Works. A minimum of three months shall be allowed for the street to settle and compact before pavement shall be constructed, or as ordered and approved by the Town Engineer or the Commissioner of Public Works. Stakes with final line and grade shall be maintained by the developer at all times to check the foundation course as well as pavement. The inclusion of the six-inch thick layer of select granular subgrade shall not be required if the Engineer can demonstrate that either the undisturbed, firm, natural subgrade solid or embankment fill meets the requirements given in § A168-23A.
B. 
Testing and certification.
(1) 
The materials to be used for the subgrade and subbase courses shall be tested in the laboratory for compliance with material specifications given for each material in the NYS DOT Standard Specification items given in Subsection A of this section of the street specifications.
(2) 
The compaction of each lift of material in the foundation course shall be verified by in-place density tests performed by utilizing the in-place Nuclear Method and/or the in-place Sand Cone Method, as specified by ASTM. Tests shall be performed at no less than one test per lift per 100 feet of roadway alignment.
(3) 
At the conclusion of construction, a licensed professional engineer shall certify that all roadway foundation courses have been placed and compacted under his/her supervision to a condition suitable for supporting this overlying pavement. This certification shall be provided in writing to the Town Commissioner of Public Works and the Town Engineer, whether the testing is performed by the Town Engineer or, where contractually required, performed by the developer's engineer.
[Amended 6-23-1988 by L.L. No. 1-1988; 3-24-2005 by L.L. No. 1-2005]
A. 
The drainage system and/or culverts shall be designed in accordance with established engineering principles and approved by the Town Engineer. A design condition of a twenty-four-hour storm having a return frequency of 10 years shall be used. Plans for any drainage structure other than pipe culverts, when existing or proposed, shall be submitted in detail to the Commissioner of Public Works for approval. The minimum grade of any drainage pipe or culvert shall not be less than 1%. The approved plans shall show invert elevations of the inlet and outlet of all drainage structures. Any deviation from the approved plans shall be on approval of the Town Commissioner of Public Works or Town Engineer, in writing. No culvert pipe shall be less than 15 inches in diameter unless by approval of the Town Commissioner of Public Works and Town Engineer. Pipe for culverts may be reinforced concrete, which shall conform to the attached specifications for materials, or HDPE pipe, which shall be in accordance with the New York State DOT Specifications.
B. 
The width of the trench in which the pipe is laid shall be sufficient to permit thorough tamping of the backfill around the pipe. A cushion of select granular fill at least six inches shall be laid in line with grade prior to laying the pipe. No rock over three inches in thickness shall protrude or lie in this cushion. The soil below the cushion shall be stable enough that there will be no settlement of pipe after backfilling the trench. All pipe bedding and backfill shall conform with the subsections listed below, as excerpted from § 203-2.02C, 203-3.15 and 603-3.03 of the New York State Department of Transportation Standard Specifications for Construction and Materials, 2002, revised 2004.

(2) 
Along the uphill sides of the roadways within cuts.
(3) 
In locations deemed necessary by the developer's engineer or the Town Engineer.
[Amended 3-24-2005 by L.L. No. 1-2005]
Roof and cellar drains shall in no case be allowed to flow onto the street right-of-way. With the approval of the Town Commissioner of Public Works or Town Engineer in writing, these drains may be piped to existing stormwater pipe drains, if any, to which they will be connected on top only. Such drains must be installed prior to the start of the application of the foundation course. Drains from sanitary sewers or septic tanks will not be permitted to flow into road ditches or storm drains under any circumstances.
[Amended 3-24-2005 by L.L. No. 1-2005]
The grade of the street shall not be in excess of 10% nor less than 1%. By permission of the Town Commissioner of Public Works only shall a grade of more than 10% be allowed due to topographic conditions. Differences in grade will be affected with a vertical curve of sufficient length to allow a vertical sight distance of no less than 250 feet, based on a four-foot elevation.
[Amended 6-23-1988 by L.L. No. 1-1988; 3-24-2005 by L.L. No. 1-2005]
Where installed, concrete curbs shall be constructed on both sides of the street as shown in Figure 1C prior to laying street pavement to the dimensions and specifications shown in Figure 4.[1] A base course of six inches of subbase material, tamped and free of stone over two inches in thickness, shall be laid under all curbing. An air-entrained concrete mix of 4,000 pounds per square inch after 28 days shall be used and shall be finished and cured to the satisfaction of the Town Commissioner of Public Works and Town Engineer. The developer, at his own expense, shall replace any curbing that has settled, cracked, scaled or has become damaged in any way by the developer before and within the one-year maintenance period after dedication. Curbs shall be depressed four inches at all driveways. Stone curbs or precast curbs may be substituted on approval of the Town Commissioner of Public Works and Town Engineer.
