§ A172-1 Purpose.

It is the purpose of this chapter to establish minimum acceptable standards of construction in the Town of Haverstraw, including but not limited to width, design, drainage, construction of pavement, curbs, sidewalks, monuments, signs, lighting and fire hydrants.

§ A172-2 State specifications.

Wherever reference is made to the Public Works Specifications of the State of New York, Department of Public Works, Division of Construction, the edition as amended shall be utilized.

§ A172-2.1 Clearing and grading.

A. 
Clearing shall consist of the removal and disposal of trees, branches, stumps, fences, debris and miscellaneous structures. No burning will be permitted and all material will be disposed of off-site except, when approved in writing by the Engineer and/or the Building Inspector, disposal in an on-site location may be permitted subject to the preparation of the area to receive the cleared material and placement of earth on top of the material, as directed. Under no circumstances is disposal to be made at a location which is designated to be built upon, or within 20 feet thereof, or in a swamp or wetland.
B. 
Where trees or existing roots/stumps shall be grubbed, excavated and removed from the area above, applicant's attention is called to § A176-17A(6)(d), which requires the depiction of existing wooded areas or trees six inches or more in diameter, measured four feet above ground level," to be presented to the Planning Board at the sketch plat stage. Removal of any tree not designated by the Planning Board to be removed shall require the applicant, for each tree so removed, to place $500 in an account established by the Town solely for replacement tree planting. The use of bulldozers or similar large equipment, rather than the use of a chainsaw, to remove trees may result in a significant loss of trees proposed to remain.
C. 
Grading shall be in accordance with the grading plan as approved by the Planning Board. In general, areas adjacent to buildings shall be sloped to direct surface water, including snowmelt, away from the buildings. Adjacent areas shall have adequate, continuous slopes to drain toward watercourses, drainage swales and roadways.
D. 
Except for approved subdivisions and site plans, any proposal to remove a tree measuring three or more inches, four feet above the original ground surface, and/or placement or removal of fill in excess of 500 cubic yards, and/or the construction of a retaining wall more than three feet in height from the highest adjacent ground level, and/or the creation of slope 20% or greater shall require written approval from the Building Inspector.

§ A172-2.2 Placement of fill.

The placement of fill, for any purpose whatsoever, is deemed to be the setting of material on top of an existing surface which results in a change in elevation of the surface upon which the fill has been placed.
A. 
Material. All material utilized for fill purposes shall be free of any and all foreign items, including, but not limited to, vegetation, bricks, concrete and other masonry materials, rock, wood, including tree stumps and branches, wall coverings, plaster, drywall, plumbing fixtures, insulation, roofing shingles, asphaltic pavement, electric wiring, metals, brush and grass clippings, glass, containers utilized for the holding of liquids, hazardous liquids, materials which may be considered infectious or biohazardous originating from hospitals, public or private clinics, research laboratories, pharmaceutical industries, blood banks, mortuaries, veterinary facilities and other similar facilities, animal carcasses, and similar materials.
B. 
Specific uses. Fill placed for specific purposes such as for public or private roads, subbase course, driveways, sidewalks, under foundations and slabs and at all other locations where the material is to be used for structural support, in addition to Subsection A, above, shall conform to the type, gradation, method of placement and compaction as specified in the Land Use Regulations of the Town of Haverstraw. Nothing shall be installed on top of the fill placed until approval is obtained from the Town Engineer and/or the Superintendent of Highways.
C. 
Nonstructural uses. Where the fill material is to be utilized solely for the purpose of grading, it may contain stone having a maximum dimension of four inches.
D. 
Off-site material. Prior to having any off-site material delivered to the construction area, the Town Engineer and/or the Superintendent of Highways and/or the Building Inspector shall be advised as to the name and location of the material source and, if required by the Town Engineer and/or the Superintendent of Highways and/or the Building Inspector, a certification prepared by the supplier shall be given indicating that the material to be delivered complies with Subsections A and B above.

§ A172-3 Street classifications.

The Town of Haverstraw Planning Board shall determine and designate into which of the five following classifications each proposed street falls:
A. 
Local street: a street whose prime function is to give direct access to abutting residential property.
B. 
Collector street: a street which collects the traffic generated by local streets and serves as a means of access from development areas to the secondary road system.
C. 
Private roads serving subdivisions of not more than three lots.
D. 
Key roads. A "key road" is a private street serving as the primary access through a multifamily residential development, a shopping center, an office development, an industrial development or other such development.
E. 
Private parking lots for multifamily residential developments, shopping centers, office developments, industrial developments and other such developments.

§ A172-4 General construction specifications; conformance required.

All roots and stumps shall be grubbed, excavated and removed from the above areas.
(3) 
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 plan and as otherwise may be directed by the Town Engineer and/or Town Superintendent of Highways. All unsuitable or unstable materials shall be completely excavated and removed from the right-of-way, and all rocks or boulders larger than six inches in diameter shall be excavated at least eight inches below the finished subgrade of road pavement, drainage or drainage structures, curbs and/or sidewalks and shall be replaced with a nonplastic selected material of a granular nature to a depth of at least six inches or as otherwise directed by the Town Engineer and/or Town Superintendent of Highways and shall be thoroughly compacted.
(4) 
The installation of all sewers, stormwater drainage and other utilities shall be made prior to placing the first pavement course.
(5) 
Where fills are necessary to complete the required line and grade or to backfill trenches or other excavation, the materials incorporated in the work shall be acceptable to the Town Engineer and/or Town Superintendent of Highways and shall be placed in layers not exceeding eight inches in depth. Each layer shall be thoroughly compacted by rolling a three-wheel, sheepsfoot, pneumatic-tired or padded-wheel roller or by impact rammer or vibratory equipment. All compaction shall continue until the fills are firm and unyielding. All work shall be certified by a New York state licensed professional engineer.
(6) 
Prior to placing the first pavement course, the Town Engineer and/or Town Superintendent of Highways shall inspect the completed subgrade, and if any unstable areas are found or observed under rolling, the material shall be removed and replaced with an acceptable material and thoroughly compacted to a depth satisfactory to the Town Engineer and/or Town Superintendent of Highways.
(7) 
The rough grade of the road pavement, curb and sidewalk areas shall be completed to within a tolerance of one inch of finished subgrade as shown on the approved cross section of the right-of-way improvement.
(8) 
Construction of road pavement, development of shoulders and drainage as herein specified shall be under the direction of the developer's engineer and to the satisfaction of the Town Engineer and/or Town Superintendent of Highways in accordance with the approval plans.
(9)
