[Amended 12-15-1993 by L.L. No. 13-1993]
No street, highway or road will be accepted for dedication as an improved road or street by the Town Board or Town Superintendent of Highways unless constructed to the following specifications and to the satisfaction of the Town Superintendent of Highways. These specifications shall apply only to those areas that cannot, by virtue of being a preexisting private road or some other special condition deemed by the Highway Superintendent, be subject to town road construction specifications found in Chapter 178, Subdivision of Land.
No road right-of-way shall be less than 60 feet in width.
[Amended 5-2-2012 by L.L. No. 1-2012]
No road pavement or metal shall be less than 28 feet in width.
Foundation course shall be laid to a compacted thickness of not less than eight inches.
Bottom course shall be laid to a compacted total thickness of three inches.
Top course shall be a three-inch asphalt concrete, Type IA.
Gutters or curbs shall be installed. Curbs shall be installed when road pavement exceeds 28 feet.
Sidewalks and planting strips between lot line and pavement shall be provided on either side of the street.
Subgrade shall be properly prepared to the satisfaction of the Town Superintendent of Highways.
Culverts used for underdrains or road crossings shall not be less than 12 inches in diameter or larger if recommended by the Town Superintendent of Highways and/or designated Town Engineer.
Catch basins shall be installed every 400 feet or as designated by the Town Superintendent of Highways.
Ditches for drainage are prohibited.
Dead-end streets are prohibited except for culs-de-sac shown on the recorded plat.
No concrete shall be laid on frozen ground.
Underground drain tile for gutters and curbs must be installed.
No road material shall be laid or placed when the air temperature in the shade is below 50° F., except with written permission from the Town Superintendent of Highways.
At all intersecting public highways, a smooth riding and satisfactory junction shall be produced by grading back to a sufficient distance with acceptable material, at no expense to the town.
All roads constructed between November 15 and April 15 will not be accepted for dedication by the Town Board until 12 months after completion and they are recommended to the Town Board for dedication by the Town Superintendent of Highways.
Embankments shall be constructed to the satisfaction of the Town Superintendent of Highways. Embankments at intersecting roads are prohibited.
Sixty-foot right-of-way of road shall be cleared of all brush, weeds, fence, stumps and other obstructions within the limits of the right-of-way.
No pavement material shall be laid until necessary drainage has been provided and the subgrade properly prepared as specified below.
The subgrade shall be properly prepared after proper drainage has been provided. All boulders, muck, quicksand, soft clay, spongy material, topsoil and any other objectionable material shall be removed as directed by the Town Engineer and Town Superintendent of Highways. All spaces from which objectionable materials have been removed shall be refilled with acceptable materials, such as stone or slag, as directed. After all drains have been satisfactorily completed and the subgrade has been properly shaped, it shall be thoroughly rolled and compacted with an approved self-propelled roller weighing not less than 10 tons. Care should be taken not to roll clay foundations enough to develop a plastic condition. All hollows and depressions which develop shall be filled with acceptable materials and subgrade shall again be rolled. This process of filling and rolling shall be repeated until no depressions develop. In places where the character of the material makes the use of such a roller impracticable, a lighter eight-ton roller may be permitted. The subgrade shall not be muddy or otherwise unsatisfactory when the pavement is placed upon it. All necessary drainage to effectively drain the roadway must be completed before the placing of any pavement will be permitted thereon.
The foundation course shall not be laid in excess of 500 linear feet without being rolled and thoroughly filled so as to render it waterproof and thereby prevent the softening of the subgrade. Should the subgrade material become churned up into or mixed with the foundation course, through any reason whatsoever, this mixture of subgrade material shall be removed and the foundation course shall be replaced to the satisfaction of the Town Highway Superintendent.
The materials may be slag or stone. Broken stone shall be Types A, B or C, New York Public Works Specifications M-4 for course aggregates. Broken slag or broken stone shall be of sizes No. 3, 4 or 5 or a uniform mixture of any of the above sizes. Crusher-run slag may be used if approved by the Highway Superintendent.
The course shall be spread, vibrated and rolled. However, the operation of filling will be required in two separate layers.
After the foundation course of stone has been spread evenly so that it will have the required thickness, after compaction, it shall be compacted over the entire surface by a mechanical vibrating tamper approved by the Engineer. Vibration shall continue until the course is keyed sufficiently to permit rolling with an approved roller without displacement of the course. The entire area of the foundation course shall be then thoroughly rolled with an approved roller weighing not less than 10 tons. Rolling shall begin at the sides and continue toward the center and shall continue until there is no movement of the course ahead of the roller. After the course is thoroughly compacted, stone screenings or sand, or a mixture of these two, in an amount approximately equal to 50% of that required to fill the voids, shall be uniformly spread upon the surface either by hand labor or by an approved mechanical device. The screenings or sand shall then be vibrated into the voids of the foundation course by a single pass of the vibrator over the entire area. This shall be followed by a second application of stone screenings, spread as specified above in an amount sufficient to fill the remaining voids in the foundation course. These screenings or sand shall then be vibrated into the voids by a single pass of the vibrator over the entire area. No further mechanical vibration shall be applied. Any area not completely filled by the above operations shall be filled by hand spreading and brooming. Care shall be exercised to see that the voids in the foundation course are completely filled, but the quantity of stone screening or sand used and the operation of filling shall not be such as to cause floating of the coarse aggregate.
The entire area shall then be rolled until free of visible voids, ruts, loose foundation course material and surplus filler.
After rolling, the foundation course shall be true to line and grade.
The bottom course shall not be laid until the foundation course has been properly laid and inspected and approved by the Town Superintendent of Highways.
The material shall be crushed slag, No. 3, rolled with a roller weighing not less than 10 tons, after which bituminous material (64P) heated to a temperature between 275° F. and 350° F. shall be evenly spread over the surface by the use of an approved pressure distributor, operating under a pressure of at least 50 pounds per square inch. The quality of bituminous material shall be not less than one and one-half (11/2) gallons per square yard of surface. The surface shall then be immediately filled with clean No. 1 broken slag, after which it shall be compacted with a self-propelled roller weighing approximately 10 tons. The entire surface shall then be rolled again.
Top course shall be a course of binder, Type 1A, with a compacted total thickness of two inches followed with one inch of fine asphalt topping.
An eight- to ten-ton roller shall be used to compact the asphalt concrete. The pavement shall conform to the grade and cross section shown on plans that have been approved by the Town Highway Superintendent and/or designated Town Engineer.
Material of culverts shall be of corrugated iron or cast iron of sufficient strength to prevent breaking under the weight of the heaviest loads the road will carry.
At all intersecting public highways a smooth riding and satisfactory junction shall be provided and produced by grading back to a sufficient distance with acceptable material, or as directed by the Town Superintendent of Highways, at no expense to the Town of Evans. Intersections of more than 75° are prohibited. Curb should be cut back at turns 30 feet from the center line of pavement.
A cul-de-sac shall provide a minimum street right-of-way of 60 feet.
Minimum transition in pavement shall be 100 feet in radius.
Minimum interior pavement radius shall be 50 feet.
Minimum pavement width shall be 28 feet.
A radius interior island of 15 feet shall be paved or landscaped.
All public utility lines, such as gas, sewers, water and drain lines, shall be installed underground before commencing construction of the road or highway.
Embankment shall be filled with only approved material. Material shall be free from frost, stumps, trees, roots, sod or muck. Material shall not be placed on frozen ground.
Embankments shall be compacted with an approved caterpillar, light tamping roller, an approved pneumatic roller or mechanical device.
Stones in earth fill shall be well distributed. No stones over four inches in diameter shall be left within 12 inches of the finished subgrade. All objectionable material shall be removed from the surface.
[Amended 12-15-1993 by L.L. No. 13-1993]
Backfill, when required, on front of pavement side or curb, shall be filled with unshrinkable fill, a controlled-density backfill that is self-compacting to reach 95% to 100% of relative optimum density. No earth fill will be allowed.
All concrete placed in cold weather must have both mixing water and aggregates heated. The concrete mix, when deposited, shall have a temperature of at least 70° F., with a maximum temperature of 110° F.
All concrete placed in cold weather shall be fully protected from the elements by being covered with suitable material for at least 10 days.
Sidewalks must be cement concrete and constructed according to FHA specifications (Date Sheet SN-101).
Minimum width of any sidewalk shall be four feet.
Minimum thickness of any sidewalk shall be four inches.
Minimum grade of sidewalk shall be not less than two inches above gutter grade.
Minimum width of a planting strip shall be five feet, measured from edge of gutter or curb to edge of sidewalk.
Minimum width of a planting strip from front lot line to sidewalk shall be one foot.
A planting strip between sidewalk and gutter or curb shall be rolled with a roller weighing not less than three tons.
All planting strips between the front lot line and edge of gutters or curbs shall be sloped, shaped, formed and trimmed to lines and grades and seeded with grass seed.
Street name signs shall be provided. Erection, location and material shall be approved by the Town Superintendent of Highways before installation.
Whenever reference is made to the furnishing of materials and specifications, the latest edition shall be used.
All materials shall be secured from approved sources and meet New York State specifications.
All construction shall be completed in accordance with the specific conditions of the commitment and the accepted drawings and specifications and in a manner acceptable to the local authorities having jurisdiction. When changes from the accepted drawings and specifications become necessary during construction, written acceptance by the civil authorities having jurisdiction shall be secured before the execution of such changes.
