Editor's Note: See Ch. 171, Subdivision of Land.
B. 
All rights-of-way dedicated to the Town of Somerset shall be without cost to the Town. The Town, in its sole discretion and as a condition of acceptance of said dedication, may require the construction of the base and pavement to be done by the Town Highway Superintendent or by an approved independent contractor pursuant to the provisions of the Town Law, and the entire expense thereof shall be paid solely by the applicants.
C. 
The Town Board reserves the right to accept or reject offers of dedication in its sole discretion.
A. 
No construction work of any drainage facilities or pavement shall be started without a construction permit. Said permit will not be issued until a subdivision map or a road dedication map has been approved by the Town Board. No subdivision map or road dedication map shall be offered to the Town Board for its approval until plans and specification for the necessary improvements have been submitted to and reviewed by the Highway Superintendent and the Town Engineer.
B. 
Application for the construction permit for drainage facilities and pavements with appurtenances shall be made to the Town of Somerset Highway Superintendent. For highways connecting to state and/or county highways, approval by the respective agency shall be indicated. Each construction permit application shall be accompanied by two complete sets of previously approved design plans and specifications. The applicant must also submit a time schedule for the work to be completed in accordance with the requirements of these standards.
C. 
Permits will be issued upon payment of a fee to be established by the Town Board. All construction work which is done without the required permit and which is in conflict with the requirements of the Town Board or is not in conformance with approved plans and specifications shall be removed or changed to meet these requirements at the expense of the applicant.
A. 
The rights-of-way for highway purposes shall have a minimum width of 66 feet for their entire length and shall intersect at an angle of not less than 75°. There shall be no dead-end roads with turnarounds unless a reserve of sixty-six-foot-wide right-of-way is provided for the future extension of a Town highway to an adjacent property.
B. 
Culs-de-sac are discouraged, but if needed for approved site development, shall conform to the minimum standards contained herein. Offsets, irregularities and short curves in the right-of-way limits can be sufficient cause for the Town Board to refuse issuance of a construction permit.
The Town Board will accept only those rights-of-way which contain all the necessary roads, shoulders or gutters, storm sewers and appurtenant structures which have been constructed in accordance with the specifications. The rights-of-way located in areas served by a sanitary sewer system and/or water distribution system must contain the facilities constructed in accordance with all permitting authorities.
The applicant shall be held responsible for all phases of the construction work shown on the application for the construction permits and shall be required to protect all adjoining property, existing highway facilities and utilities. The applicant shall be required to repair or replace any such properties or facilities damaged or destroyed by him or his employees through the construction operations.
Legal deed conveyances to the Town of Somerset for rights-of-way shall include a fully dimensioned plot giving all center-line data and measurements in accordance with accepted surveying practices. The plot shall be drawn accurately to a scale of no less than one inch to 100 feet on a sheet, sizes of 8 1/2 inches by 11 inches or 11 inches by 17 inches or 22 inches by 34 inches or 24 inches by 36 inches. The legal deeds must be accompanied by three copies of the plot.
A. 
Observation of construction to obtain compliance with these standards and any special conditions of the permit for construction shall be in accordance with the following procedure:
(1) 
Any person receiving a permit for construction under these standards shall be required to pay for the services of an observer appointed by the Town during the installation of the improvements and shall, before commencing the work, furnish a bond or cash deposit in an amount to be determined by the Town Board to insure payment of such observer.
(2) 
The applicant shall be required to notify the Highway Superintendent in writing before commencing with the work. The Superintendent and the designated observer shall be notified by the applicant no less than 24 hours before the commencement of work and shall keep the observer advised as to the work installation schedule in order that the work may be properly and fully observed at all stages of the installation. Any construction work that is done without the required observation shall be subject to verification of compliance, and the expense for this shall be borne by the applicant.
B. 
Upon satisfactory completion of the work, the applicant will be issued a certificate at completion by the appropriate Town Superintendent.
A. 
Clearing, except as otherwise specified, includes the removal or destruction of all fences, trees, roots, stumps, hushes, timbers and decayed or growing organic matter above and below the surface of the ground within the limits of the work in the right-of-way to the extent shown on the drawings or as determined by the Superintendent.
B. 
The applicant shall use every precaution to prevent injury to buildings, roads, curbs, pipes or poles, trees and shrubs and utilities. He shall repair or replace any damage done due to negligence on his part. Materials removed, unless otherwise specified, shall become the property of the applicant and shall be removed from the job site.
C. 
Excavation shall consist of the loosening, loading, depositing rough and fine grading and the compacting of all materials of every name and nature, wet or dry, necessary for the preparation of subgrades or roads, forming ditches, trenches and pits for structures, to grade the site to the elevation shown on the drawings or as required to make embankments and fills for obtaining material from borrow pits, other than borrowed topsoil or for any other operation necessary to complete the work of the contract.
A. 
All road grades shall be established in a manner to provide maximum safety. The minimum acceptable grade is six inches per 100 feet or 0.5%, and the maximum acceptable grade is 10 feet per 100 feet or 10%.
B. 
All changes in grade shall be accomplished by vertical curves, and the maximum change in grade shall not exceed 10%. All vertical curves shall be separated by a minimum of 50 feet of tangent grade. The minimum length of vertical curve for the changes in grade is shown in the following table:

C. 
Where topography is such as to create severe hardships, the Highway Superintendent may grant variations to these requirements.
A. 
Proper drainage on new roadbeds shall be provided as shown on the typical section. Provisions shall be made to have all tiles and storm sewers drain to a natural drainage area. Where it becomes necessary to transfer drainage from one side of the road to the other, proper crossovers of N-12 high-density polyethylene (HDPE) smooth interior, corrugated galvanized iron or concrete pipe shall be used, subject to the approval of the Highway Superintendent.
B. 
Minimum size of culvert pipe is to be 12 inches in diameter. All pipe shall be designed to support an H-20 loading. Corrugated galvanized iron pipe shall be coated inside and outside; arch pipe shall have a paved invert. Culvert pipe crossing the road pavement shall have 12 inches minimum cover from the road subbase. Culverts crossing driveways shall have 12 inches minimum cover.
C. 
On crossovers, precaution should be used not to overload natural drainage ditches with an excessive amount of drainage. Headwalls and/or end sections shall be constructed to Town specifications on all drainage lines within the right-of-way to prevent erosion and washouts of fill around drainage pipes.
D. 
Catch basins, gutters, underdrains and preformed end sections shall be as shown on drawings. When unsatisfactory conditions exist and extra drainage is required, it shall be provided by the applicant when directed by the Highway Superintendent.
E. 
When roadside ditches are deemed acceptable, they shall have a minimum grade of 0.33%. Ditches shall be located within the right-of-way, unless otherwise approved to be located in an easement area. Storm sewers shall be provided in areas that proper shoulder width and ditch slopes cannot be maintained due to ditch depths.
A. 
Subgrades for roadways shall be accurately shaped and crowned to the grades and levels shown on the drawings or as directed. In the process of preparing subgrades for roadways, all topsoil must be removed on both present grade levels and where fill is required to raise the present grade levels.
B. 
If fill is required, it is to be applied in not more than eight-inch layers and rolled before additional fill is added. Fill for subgrades for pavement shall be compacted with an approved self-propelled roller weighing not less than 10 tons. Subgrades shall be rolled only during the time of optimum moisture content and to the satisfaction of the Highway Superintendent.
C. 
In cases where soft clay, quicksand, muck, wet spots or other unsuitable material is encountered in the subgrade, it shall be removed to the limits designated by the Highway Superintendent and properly drained with six-inch perforated pipe weeps to the storm drainage system and then refined with dry material or granular materials as directed by the Highway Superintendent and then properly compacted to maximum density and bearing capacity. Granular material shall be ROC stone, as acceptable to the Highway Superintendent.
D. 
The subgrade material shall be spread in such depths that the thickness of any layer, after compaction, shall have a maximum of eight inches. Water shall be added in such amounts as the Highway Superintendent may consider necessary to secure satisfactory compaction.
E. 
When the moisture content of the layer is within the limits for proper compaction, the entire surface shall be rolled with a pneumatic-tired roller having an operating weight of between 1,000 and 2,500 pounds per tire or a smooth-wheel roller having a minimum weight of 10 tons. Each portion of the layer shall be covered by a minimum of eight passes of the roller.
F. 
For heavier and more efficient types of rolling equipment, the minimum number of passes required on all portions of the layer shall be determined by the Highway Superintendent after appropriate field tests to evaluate the efficiency of the equipment. In limited areas where the use of a roller is impractical, approved mechanical tampers shall be used to compact the material.
G. 
After compaction, the course shall be true to grade and cross section. Any depressions that develop during rolling shall be filled with additional granular material and further rolled until the entire surface of the subgrade is true to grade and cross section. Should subgrade become churned up into or mixed with the granular material through any cause whatsoever, the applicant shall, at his own expense, remove such mixture of soil and granular material and replace with additional granular material.
A. 
Minimum drainage requirements shall consist of four-inch perforated pipe in stone or approved equal for underdrains at each edge of pavement with underdrain relief, not more than 400 feet to the storm drainage system, as shown on the Highway Standard Detail. Where extraordinary conditions exist, additional drainage provisions, as directed by the Highway Superintendent, shall be provided.
B. 
All waterlines, storm sewer and sanitary sewers shall be installed prior to the work or preparing the subbase and the pavement drainage. Where waterlines, storm sewers and sanitary sewers are to cross the roadway, such crossings shall be made before the placement of any pavement material.
C. 
Trenches for these utility crossings in the pavement and gutter or shoulder areas shall be backfilled with No. 2 run-of-crusher stone or slag from the elevation of the initial bedding of the utility to the elevation of the subgrade. These crossings of the pavement areas shall be reviewed by the Highway Superintendent or his designated representative before the commencing of paving operations.
D. 
All storm sewer pipe, catch basins, manholes, grating, etc., will be provided as shown on the construction standard detail drawings.
After the subgrade has been prepared, the filter fabric shall be installed as shown on the highway cross-section detail and in accordance with New York State Department of Transportation (NYSDOT) standards.
If gutters are required after the subgrade has been prepared, the filter fabric placed, and the proper drainage provided and the Highway Superintendent has reviewed the work for compliance with the plans, the first six-inch bottom course may be placed and compacted for the total width of the pavement, or not less than four feet in width centered over the drain tile. The contractor shall then place the forms and construct the standard gutters. After the forms are pulled, the outside voids shall be backfilled before the second course is spread and compacted.
A. 
After the subgrade has been prepared, the filter fabric placed and the proper drainage and gutters, if required, have been provided and the Highway Superintendent has reviewed the work for compliance with the plans, a course of approved run-of-crusher stone shall be evenly spread with spreader equipment to an even thickness so when rolled it will produce two courses with a compacted thickness of not less than six inches for each course.
B. 
The roller shall be an approved self-propelled type weighing not less than 10 tons. Rolling of each course shall begin at the sides and continue toward the center of the road. Rolling shall be repeated until the stone particles are thoroughly keyed in place and until there is no movement or weaving of the course ahead of the roller.
C. 
It is imperative that the second course conform accurately to the line and grade specified and shown on the plans. If the subgrade material shall become churned up into or mixed with the bottom course through any reason whatsoever, the applicant shall, at his own expense, remove such mixture of subgrade material and crushed stone or slag and replace with new crushed stone or slag placed in accordance with the procedure outlined above.
D. 
After proper compaction has been attained for each course and inspected and approved by the Highway Superintendent, the surface of each course shall then be immediately filled (chinked) with Clean No. 1 broken stone, after which it shall be compacted with a self-propelled roller weighing not less than 10 tons.
E. 
After compaction, the top surface of these courses shall not extend above the theoretical grade elevation for these courses.
A. 
After the bottom courses are properly prepared, the contractor shall install the bituminous plant mix surface pavement, as per Section 401 of the New York State Department of Transportation Specifications.
B. 
The surface pavement shall consist of four inches followed with a top course of 403.16 with a compacted thickness of two inches. A ten-ton self-propelled, steel-wheeled roller or an approved equal shall be used to compact these surface courses.
C. 
The surface shall be tested with a sixteen-foot straight edge or string line placed parallel to the center line of the highway or on any portion of the highway surface. Variations exceeding 1/4 inch shall be satisfactorily eliminated or the pavement relaid at the expense of the applicant.
The Town Highway Superintendent may vary or modify any of the requirements herein which he determines to be in the best interest of the Town of Somerset.
