The road and drainage plans submitted by the subdivider shall be complete enough to be used as construction plans for the roads and drains in the plat. Plans shall be approved by the Engineer prior to the start of construction. All plans shall be prepared by an engineer licensed in New York State.
The crushed stone or gravel base shall be placed as shown on Illustration No. 1.
It shall meet the following gradation requirements (United States standard sieve):
Requirements for soundness, plasticity and elongation shall meet those set forth for Item 304, Subbase Course, in the New York State Department of Transportation "Standard Specifications" of latest issue.
Surfacing shall consist of a double layer of asphalt concrete; the lower layer shall be four-inch-thick Type 3 binder course; the upper layer shall be one-and-one-half-inch-thick Type 7 top course; the asphalt surface shall be 24 feet in width.
Where the proposed subdivision lies entirely along a road which is maintained by a public agency, road surfacing shall be omitted. All other sections shall apply as to their effect on an existing road.
Editor's Note: Said illustration is on file in the village offices.
The subdivider shall incorporate concrete rolled gutters along both sides of the new roadway. The gutter shall have a minimum thickness of six inches and a width of three feet. (See Concrete Curb Section Illustration No. 1-A for details.)
The concrete shall adhere to the following mix design:
All curb sections, plans and profiles shall be submitted for approval by the Village of Springville.
Editor's Note: Said illustration is on file in the village offices.
Sidewalks will be required by the Planning Board and shall be not less than four inches thick except at driveways, where the thickness shall be six inches. Concrete design mix shall be as described for concrete gutter and shall contain reinforcing. The reinforcing shall be either six inches by six inches by ten-gauge welded wire mesh or fibrous reinforcement acceptable to the Village of Springville. Installation and construction techniques shall follow guidelines set in the New York State Department of Transportation "Standard Specifications" of latest issue.
Other items not included in these specifications shall be approved by the engineer prior to design completion or start of construction.
No utility shall be placed under the roadbed, except for crossings, unless all service lines for each lot are installed as part of initial utility construction. Water main service lines shall end with the curb box at the property line. Sanitary sewer laterals shall end at the right-of-way line and shall be marked using pressure-treated two-by-fours that reach from the lateral vertically to a point two feet above finish grade.
All roads, including existing public roads, shall be provided with facilities for adequate surface and subsurface drainage.
If subsurface drainage is deemed necessary by the village, the subdivider shall provide for the same in a manner acceptable to the Engineer.
Any areas of the subdivision which do not drain into the subdivision drainage system shall be shown on the plan with a note indicating disposition of water accumulating on such areas.
Drainpipes under roads or driveways shall be designed to withstand New York State highway loadings.
A certified analysis of all intended material (includes bituminous, culverts, concrete, gravel, stone, etc.) shall be filed with the Engineer for approval prior to placing the material.
The analysis may include an affidavit from the supplier or may be made by a laboratory approved by the Engineer, or both, as required.
All brush, shrubs and roots thereof shall be entirely removed from the right-of-way of all roads and alleys in the proposed plat. All trees, including the roots thereof, within the roadway and ditch lines shall be entirely removed. Trees outside the roadway and ditch lines may not be removed unless approved by the village.
All topsoil shall be removed from the roadway before any surfacing material is placed. No topsoil or other fill material may be removed from the subdivision without approval from the Planning Board.
Any deleterious material in the subgrade shall be removed and replaced with material which is approved by the Engineer.
The earth grade shall be brought to the required elevation, smoothed, trimmed, drained and compacted before any surfacing material is placed.
Soft spots in the earth shall be corrected by removing improper materials and replacing with materials approved by the Engineer.
The subgrade and crushed stone or gravel base shall be rolled and thoroughly compacted with a ten-ton roller.
Upon completion of installing and compacting base material, the entire roadway surface shall be treated with an asphalt emulsion Type MC-30 at an application rate of 0.5 gallon per square yard. This sprayed application shall be allowed to set for 24 hours prior to paving.
Place and roll asphalt concrete binder course and top course in accordance with the New York State Department of Transportation "Standard Specifications" of latest revision.
All construction must be done under the supervision of a New York State licensed engineer.
All work not provided for elsewhere in these specifications shall be done in a manner approved by the village.
Tree planting. At least two trees, having a minimum of a one-inch thick or a five-foot height, shall be planted on each lot and located between the right-of-way line and setback. Such trees shall be maintained in healthy condition for a period of at least one year. Species and location shall be approved by the Planning Board. This item may be waived where established trees are in existence.
The following drawings are annexed to this chapter and depict the specifications and engineering details of the required plans, methods and materials to be applied and used in presenting, constructing and installing the referenced road and drainage improvements shown thereon:
[Added 3-20-2006 by L.L. No. 2-2006]
Editor's Note: Said drawings are included at the end of this chapter.
After construction is completed, the subdivider shall request approval, in writing, of the work. The request shall be accompanied by a sealed certification from the subdivider's engineer that he has supervised and inspected all construction and that all work is in accord with the approved plans and specifications.
Such certification shall include as-built plans where revisions in the approved plan were required by conditions encountered during construction.
As-built plans shall be submitted for sanitary sewers and water mains. The location of all service Y's and laterals shall be shown on the as-built plans. Service Y and lateral locations shall be witnessed by a dimension, in feet, to the nearest downstream manhole center or water main valve. Where a service lateral is extended from a Y, the end of the lateral shall be witnessed by an appropriate dimension and angle. In addition to witness measurements, a pressure-treated two-by-four shall reach from the service lateral vertically to a point two feet above finish grade.
The Engineer and department heads shall inspect the work as soon as possible after the requirements of Subsection A are complete. If the work is complete and acceptable, recommendations shall be given to the Planning Board for acceptance by the village. If the work is not approved, the developer shall be notified as to deficiencies. A reinspection will be required if deficiencies are found.
