A. 
Before the Planning Commission may approve a subdivision plat containing residential units, such subdivision plat shall also show, when required by such Commission, a park or parks suitably located for playground or other recreational purposes. Such park or parks shall contain no less than 10% of the gross land area of the subdivision.
B. 
Land for park, playground or other recreational purposes may not be required until the Planning Commission has made a finding that a proper case exists for requiring that a park or parks be suitably located for playgrounds or other recreational purposes within the village. Such findings shall include an evaluation of the present and anticipated future needs for park and recreational facilities in the village based on projected population growth to which the particular subdivision plat will contribute.
C. 
In the event that the Planning Commission makes a finding pursuant to Subsection B above that the proposed subdivision plat presents a proper case for requiring a park or parks suitably located for playgrounds or other recreational purposes but that a suitable park or parks of adequate size to meet the requirement cannot be properly located on such subdivision plat, the Planning Commission shall require a sum of money in lieu thereof, in an amount to be established by the Board of Trustees. In making such determination of suitability, the Commission shall assess the size and suitability of land shown on the subdivision plat which could be possible locations for park or recreational facilities, as well as practical factors, including whether there is a need for additional facilities in the immediate neighborhood. Any moneys required by the Planning Commission in lieu of land for park, playground or other recreational purposes pursuant to the provisions of this section shall be deposited into a trust fund to be used by the village exclusively for park, playground or other recreational purposes, including the acquisition of property.
D. 
Existing features which would add value to residential development, such as large trees, watercourses, historic spots and similar irreplaceable assets, should be preserved insofar as possible, through harmonious designs of the subdivision.
E. 
The layout of the proposed subdivision shall be in general conformity with the features or developments proposed in the Master Plan of the Village of Colonie.
F. 
All roads, parks and required easements shall be indicated on the plat. Formal offer of cession to the public of all roads and parks to be offered to the public shall be filed with the Planning Commission prior to approval of the plat by the Planning Commission. The applicant may add, as part of the plat, a notation, if he so desires, to the effect that no offer of decision of such roads and parks or any of them is made to the public.
As to utilities required by the Planning Commission, the Commission may accept assurance from each public utility company whose facilities are proposed to be installed. Such assurance shall be in writing, addressed to the Commission, stating that such public utility company will make the installation necessary for the furnishing of its services within a specified time in accordance with the approved construction detail sheets submitted.
Construction standards for all required improvements shall be in accordance with the standards established by the Village Planning Commission. The standards shall also conform to the Official Map, as adopted. Alternate improvement standards may be permitted if the Planning Commission deems that they are equal or superior in performance characteristics to the specified improvements.
Monuments shall be placed so that the scored or marked point shall coincide exactly with the intersection of the lines to be marked and shall be set so that the top of the monument or marker is level with the surface of the surrounding ground.
A. 
Monuments shall be set at the intersection of all lines forming angles in the boundary of the subdivision.
B. 
Markers shall be set at the beginning and ending of all curves along street or highway 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 lot corners. Markers shall consist of steel bars at least 15 inches long and not less than three-fourths (3/4) inch in diameter.
C. 
Permanent monuments shall be set at block corners and at intervals of approximately 500 feet or such other distance as the Planning Commission may determine appropriate, and their location shall be shown on the subdivision plat. Unless embedded in concrete, iron pipes shall not be considered permanent monuments for the purpose of these regulations. Permanent monuments shall be set to prevent their movement due to normal frost upheaval pressures and movements.
A. 
The developer shall be required by the Planning Commission to carry away, by pipe or open ditch, any spring or surface water that may exist either previously to or as a result of the subdivision. Such drainage facilities shall be located in the road rights-of-way, where feasible, or in perpetual unobstructed easements of appropriate width.
B. 
A culvert or other drainage facility shall, in each case, be large enough to accommodate potential runoff from its entire upstream drainage area, whether inside or outside the subdivision. The subdivider's engineer shall determine the necessary size of the facility, based on conditions of total potential development and guidelines of the New York State Department of Environmental Conservation. The developer shall submit to the Planning Commission three copies of computations and data in sufficient detail to make possible the ready determination of the adequacy of the proposed drainage installation.
C. 
The subdivider's engineer shall also study the effect of each subdivision on existing downstream drainage facilities outside the area of the subdivision. Where it is anticipated that the additional runoff incident to the development of the subdivision will produce downstream flows which will exceed the guidelines of the New York State Department of Environmental Conservation, in such case the Planning Commission shall not approve the subdivision until provision has been made for the improvement of said potential condition.
(1) 
Lots shall be laid out and graded to provide positive drainage away from buildings.
(2) 
Culverts and related installations shall be provided to:
(a) 
Permit unimpeded flow of natural watercourses.
(b) 
Ensure adequate drainage of all low points along the line of streets.
(3) 
In the design of storm installations, special consideration shall be given to avoidance of problems which may arise from concentration of stormwater runoff over adjacent properties.
A. 
The developer shall be required by the Planning Commission to pipe such location or locations as the Planning Commission may require all present or future sanitary sewage generated within or tributary to his development, as determined by the Planning Commission.
B. 
All pipe and appurtenances shall, in each case, be of sufficient size to accommodate such flows as will be developed by the design requirements established by the Superintendent and/or the Albany County Department of Health and meeting the approval of the Planning Commission. The developer shall submit to the Planning Commission for review and approval three sets of computations and data in sufficient detail to make possible the ready determination of the adequacy of the proposed system.
C. 
The Planning Commission reserves the right to reject any proposed development which will exceed the capacity of the downstream system.
D. 
Where the required system or any part thereof cannot be accommodated within the right-of-way of any presently existing or proposed street or road, the developer shall provide an unrestricted easement in perpetuity extending a minimum of 15 feet on either side of such system or part thereof.
All bonds, letters of credit or cash required under these regulations will be released by the Planning Commission after certification by the Village Engineer that the work covered by the bond, letter of credit or cash has been satisfactorily completed, except that 10% of the original amount shall be retained for a period of two years to cover repairs to the work covered by the original bond, etc., including replacement of trees required by the Planning Commission. The requirement to replace trees shall be enforced by the Chief Code Enforcement Officer. The remaining 10%, or as much of it as is left over after paying for any repairs or replacements during the period of retainage, will be released by the Planning Commission on recommendation of the Village Engineer after the expiration of the two-year retainage period.
