A. 
Minimum improvements and construction standards required of all subdivisions shall be as set forth in this article and as listed in Table 3. Where not set forth, they shall be in accordance with the prevailing standards as established by the Planning Board. Alternate improvement standards may be permitted if the Planning Board deemed them equal or superior in performance characteristics to the specified improvements. Additional or higher type improvements may be required in specific cases by the Planning Board in order to create conditions essential to the health, safety, morals and general welfare of the citizens of the municipality.
B. 
The Planning Board may, subject to appropriate conditions, waive the provision of any or all such improvements and requirements which, in its judgment, are not required in the interest of the public health, safety and general welfare or which are inappropriate because of the inadequacy of connecting facilities.
A. 
Monuments.
(1) 
Monuments shall be placed so that the scored or marked point shall coincide with the intersection of the lines to be marked and shall be set so that the top of the monument is level with the surface of the surrounded ground. Monuments shall be readily visible and shall be set at the intersection of all lines, forming angles in the boundary of the subdivision and at all block corners. Monuments may be of the following two types.
(a) 
Cut stone four inches by four inches by 48 inches long, with a drill hole in the center.
(b) 
Concrete four inches by four inches by 48 inches long, properly marked at the center.
(2) 
The proposed replacement of any existing monuments shall be clearly indicated on the final plat.
[Amended 3-10-1988 by L.L. No. 1-1998]
B. 
Markers' Iron pin markers shall be set at the beginning and ending of all curves along street property lines; at all points where lot lines intersect curves, either front or rear; at all angles in property lines of lots; and at all corner lots. Markers shall consist of a steel pipe at least 18 inches long and not less than 3/4 inch in diameter.
A. 
The provision of street pavement, curbs and sidewalks on all proposed or required public streets shall be as shown on Table 4. All streets shall be graded, surfaced and improved to the grades and dimensions shown on plans, profiles and cross sections submitted by the subdivider and approved by the Planning Board.
B. 
Table 4 specifies those improvements which are the responsibility of the subdivider. In the case of arterial and connector streets, the State Department of Transportation may provide additional improvements over and above those required to be installed by the subdivider.

NOTES:
1
The letters in the table (A through E) refer to the following proposed construction standards:
Street pavement.
A.
Two and one-half inches of asphalt concrete, Type 2A surface course placed over a stone base course, both in accordance with the latest specifications of the State Department of Transportation. The thickness of the stone base course shall be 12 inches for arterial streets, 10 inches for connector streets, eight inches for collector streets and six inches for minor streets.
B.
Two inches of asphalt concrete, Type 3A surface course in accordance with the latest specifications of the Department of Transportation, placed over six inches of run-of-bank gravel in accordance with the specifications of the Planning Board.
Curb types.
C.
Plain cement, reinforced concrete curb eight inches at the top, nine inches at the bottom and 24 inches in height, with the slope to the street side.
D.
Valley gutter: plain cement, reinforced concrete curb 24 inches wide, nine inches at maximum width.
Sidewalks.
E.
Concrete sidewalk four inches in thickness placed on a four-inch cinder or crushed stone base.
2
When the arterial street and connector street are under the jurisdiction of the New York State Department of Transportation or the Livingston County Highway Department, the respective agency will determine the requirements.
3
The indicated width will be used except for a marginal access street, where a pavement width of 24 feet shall be required.
A. 
Street signs, streetlighting and fire alarm signal devices shall be provided at appropriate locations on all streets. The type, height and design shall be approved by the Planning Board.
B. 
Trees shall be provided in all residential subdivisions of a type compatible with local conditions. Such trees shall be planted in the front yard setback area, spaced at intervals of not more than 50 feet. The size, type and species of such trees shall be approved by the Planning Board.
A. 
Provision of water supply. Where public water supply, in the opinion of the Planning Board, is reasonably accessible, the subdivision shall be provided with a complete water distribution system, including a connection for each lot and appropriately spaced fire hydrants, which shall not be greater than 500 feet apart. Where public water supply is not within reasonable distance, an alternate supply, approved by the State Department of Health, shall be furnished.
B. 
Locations of waterlines. Where public waterlines are installed, all such waterlines shall be located between the curbline and the property line within any street right-of-way.
A. 
Public sewer system. Where the public sanitary sewer, in the opinion of the Planning Board, is reasonably accessible, sanitary sewers shall be installed to adequately serve all lots with connections to the public system.
B. 
On-lot sewage and water tests. Where evidence indicates that the minimum lot size requirements specified in other sections of these regulations or in any applicable Zoning Ordinance are not adequate to permit the installation of individual on-lot water supply and/or sewage disposal facilities, the Planning Board may require that the subdivider request the State Department of Health to make such tests as are necessary to determine the adequacy of the proposed facilities in relation to the proposed lot size, existing grade and soil conditions. In all such cases, a certificate from such Health Department indicating that the proposed facilities are adequate shall be prerequisite to final approval of the plan.
C. 
Capped sewers. Where the municipality has a plan for extending the public sanitary sewer system into an area that is being subdivided and it is reasonably expected that the area will be served by the public system within a period of five years, capped sewers shall be installed to adequately serve all lots in the proposed subdivisions.
D. 
Location of sewer lines. Whenever sanitary sewers are provided, they shall be located as near to the edge of any street right-of-way, out of the paved area, as is reasonably possible, and all such sewer lines shall provide service connections being properly capped.
[Amended 3-10-1988 by L.L. No. 1-1998]
E. 
Type of sewer system. No combined sanitary and storm sewer systems will be permitted.
F. 
Manholes. Sanitary sewer manholes will be provided at all changes in grade and direction, and in no instance shall the distance between said manholes exceed 400 feet.
A. 
Provision of storm sewers. Storm sewers and related drainage facilities shall be installed. Such facilities shall provide a clear channel adequate to handle runoff from a ten-year storm.
B. 
Purpose of storm sewers. When storm sewers, culverts and related installations are provided, they shall be designed as follows:
(1) 
To permit unimpeded flow of natural watercourses.
(2) 
To ensure adequate drainage of all low points along the line of streets.
(3) 
To intercept stormwater runoff along streets at intervals reasonably related to the extent and grade of the area drained and at all intersecting streets.
C. 
Special problems. In the design of storm sewerage installations, special consideration shall be given to avoidance of problems which may arise from concentration of stormwater runoff over the adjacent properties.
D. 
Construction standards. All drainage structures, culverts, boxes, grates, etc., shall conform to the current specifications of the Department of Transportation, as approved by the Planning Board.
A. 
Electric power, telephone and television community antenna lines. All subdivisions shall have easements provided for the installation of electric power and telephone utility lines to serve each and every lot, and provision shall be made, when necessary, for the location of television community antenna lines to be installed in said easements. Electric power and telephone utility lines shall be installed underground.
B. 
Gas transmission lines. When any subdivider proposes to provide gas transmission lines within a subdivision, said gas transmission lines shall be installed underground between the curbline and the property line of any street right-of-way located on the opposite side of the street from waterlines.
[Amended 3-10-1988 by L.L. No. 1-1998]
The subdivider shall install the required improvements under the supervision of the Zoning Enforcement Officer. Subdivisions may be developed in stages or sections and the subdivider shall guarantee the installation and maintenance of the minimum improvements in each such stage or section in the following manner prior to the approval of the final plat:
A. 
By posting with the Planning Board a certified check or bond running to the municipality in an amount sufficient to cover the full cost of installing the required improvements in such stage or section as estimated by the Zoning Enforcement Officer. In case of a bond filed, it shall also be with surety satisfactory to the Planning Board and it shall specify the time for the completion of the improvements and installations in such stage or section, such time to be satisfactory to the Planning Board.
B. 
By posting a maintenance bond to guarantee maintenance and repair of the streets in the subdivision for one year after the construction has been approved by the Planning Board and acceptance of improvements has been completed by the municipality.
