A. 
The following improvements shall be required in all subdivisions except where waived by a specific resolution of the Commission: storm sewers and pavement on proposed streets, as well as curb and pavement between the edge of the existing pavement and the new curbline on existing streets which bound or intersect the proposed subdivision. The developer shall also be required to install street signs, wire utilities, monuments, driveway aprons, loam and seeding and shade trees. The Commission may also require the installation of street lights, sidewalks, curbs, sanitary sewers and fire hydrants. Such improvements shall be installed in accordance with Town, state highway or utility company standards. In any event, no site improvement work including grading shall be started for any contemplated subdivision or resubdivision before the Commission has granted approval of the subdivision plan and until a bond in compliance with Article V of this chapter has been furnished. The Commission may accept assurance, in writing, from each utility company whose facilities are proposed to be installed in the subdivision, in lieu of bond, covering such utilities.
B. 
All construction shall be in accordance with the Woodbridge Road Specifications on file in the Office of the Commission.
C. 
"The Rules and Regulations of the State Board of Registration for professional engineers and land surveyors" shall apply to all technical work done in conjunction with subdivisions. The technical responsibilities of the licensed professional engineer and land surveyor in regard to subdivision work are:
(1) 
The design of roads, both horizontal and vertical alignment; drainage systems, including the design and location of structures and pipe; sanitary sewer systems; sewage disposal systems; and water supply and distribution constitute professional engineering and as such shall be signed and sealed by a licensed professional engineer. A land surveyor's seal or an architect's seal is not acceptable for this phase of land subdivision design.
(2) 
The phase of land subdivision which relates to topographic maps and the delineation of the boundary lines of the outside perimeter as well as the interior lots and street constitutes land surveying within the meaning of the statute and as such shall be certified and sealed by a licensed land surveyor. A professional engineer's seal or architect's seal is not acceptable.
A. 
Layout. The roads and highways shall conform to the plan of development for roads and highways.
B. 
Road arrangements. The arrangement of the roads in the subdivision shall provide for the coordination of principal roads and existing roads, and for proper projection of principal roads into adjoining properties which are not yet subdivided, in order to make possible necessary fire protection, movement of traffic, and the construction or extension, presently or when later required, of needed utilities and public services such as sewers, water and drainage facilities. When topographic or other conditions make such continuance impracticable in the opinion of the Commission the above requirements may be modified in compliance with Article X of this chapter.
C. 
New roads. Where the subdivision adjoins unsubdivided land capable of being subdivided, the Commission may require new roads to be carried to the boundaries of the proposed subdivision. Where proposed roads do not extend to, or are not adjacent to, the boundaries of the tract, they shall be separated from such boundaries by a distance of not less than 200 feet. Reservation of title in any land controlling access to roads is otherwise prohibited.
D. 
Reserved rights-of-way. When required by the Commission the subdivider shall dedicate to the Town a reserved right-of-way for future road connections to adjoining properly susceptible of being subdivided. Such reserved right-of-way shall be included into an adjoining lot subject to a permanent easement to the Town. All yard measurements shall be made from the center line of the reserved right-of-way with said yard to be treated as front yard. Necessary slope rights outside of such reserved right-of-way shall also be shown and reserved to the Town. This right-of-way shall have necessary radial intersections. When adjoining property is subdivided the developer of said adjoining property shall be required to connect and build the road over the reserved right-of-way at his own expense.
E. 
Road widths. Minimum width for roads shall be as required by the Woodbridge Road Specifications. Wider roads than those specified above may be required where the Commission deems them to be necessary. Where a subdivision abuts or contains an existing road which does not comply with the specified width requirements, the subdivider shall dedicate the necessary area to the Town for road widening and show such widening on the subdivision plan. The subdivider shall also be responsible for the construction of such improvements at his cost.
F. 
Side slopes. Roads in cut or fill shall be provided with side slopes not steeper than six feet horizontal to one foot vertical. In all areas where the side slopes are steeper than four feet horizontal to one foot vertical and slope down from the road, protective devices shall be installed in accordance with the Woodbridge Road Specifications. Where new roads abut private property and such property is affected by the proposed cut or fill, necessary slopes rights shall be obtained by the developer and these slope rights shall be shown on the subdivision plan submitted to the Commission. The developer shall investigate the effect of fills an adjacent private property within the slope right area. The developer shall also provide the Town with evidence that no drainage problems or other problems shall arise on adjacent property due to construction or fill operations.
G. 
Relation to topography. The road of a proposed subdivision should bear a logical relationship to the topography, and all roads should be arranged so as to obtain as many of the building sites as possible at or above the grade of the road. All natural features shall be preserved where so required by the Commission.
H. 
Energy conservation and solar access. All subdivisions shall consider using passive solar energy techniques in planning the street layout as provided for in Article I, § 490-2A of this chapter.
I. 
Intersections.
(1) 
No more than two roads shall intersect or meet at any one point and the center line of all roads entering an intersection shall pass through a single point. Except where impracticable because of topography or other conditions, all roads shall join each other so that for a distance of at least 100 feet the road is approximately at right angles to the road it joins. Except where impracticable because of topographic or other conditions a road shall not have a grade in excess of 3% for the first 100 feet from the center point of the road intersection and it shall not have a grade in excess of 5% for the next 100 feet. At all road intersections all sidewalks required to be installed by the Commission shall be provided with ramp access for handicapped persons.
(2) 
The center line of any new road shall not join or intersect an existing Town or state highway at a distance less than specified below from the point at which any other road joins or intersects the same existing Town road or State Highway, unless, at the point of such center line juncture or intersection, such road is a continuation of an existing Town road or State Highway.

(3) 
The subdivision plan shall be submitted by the applicant to the Bureau of Highways, Connecticut Department of Transportation, if a proposed road in the subdivision intersects with a State Highway. In such instance the approval of the Bureau of Highways, Connecticut Department of Transportation shall be obtained in writing and submitted to the Commission with the application for a subdivision plan.
J. 
Sight vision protection on corner lots. On all corner lots sight vision protection by grading and removal of barriers, shall be provided and maintained as required by the Zoning Regulations of the Town. The sight vision protection area of a corner lot within a proposed subdivision shall be delineated and identified as such on the subdivision plan.
K. 
Watercourses. Where access from a road to property which is to be subdivided requires the crossing of a watercourse provision shall be made to carrying such water course by means of culverts or other structures. Any new drainage ditch shall be constructed so that it shall have a flat bottom of sufficient width to carry the anticipated flow of water and shall have sides at a grade of no greater than one foot vertical to 1 1/2 feet horizontal, such sides shall be laid in stone, rip-rap or maintained in grass. The Commission may also require that stormwater be piped.
L. 
Maintenance of unaccepted subdivision roads. The developer shall be responsible for the complete maintenance of all subdivision improvements including snow plowing, road sweeping, drainage, etc., until such improvements are accepted by the proper Town authorities. In the event that the developer fails to comply, this chapter authorize the proper Town department to perform the necessary work, without incurring any liability therefor, and such work shall be charged to the developer.
M. 
Dedication of road. Approval of a subdivision plan shall not be deemed to constitute or effect an acceptance of any road by the Town. However, the filing of an approved subdivision plan shall constitute an irrevocable offer of dedication of said road to the Town for highway purposes.
N. 
Street signs. Street name signs shall be erected by the developer at his cost at points designated by the Commission and shall be shown on the subdivision plan. They shall be of a material and installation in accordance with Town specifications.
O. 
Vertical design criteria. The minimum grade of all roads shall be 1%, except at the intersection of vertical curves. The maximum grade on Class B roads shall be 5% and on Class C roads 10%. All changes in grade shall be connected by vertical curves so that clear visibility shall be provided for a minimum stopping sight distance of 250 feet on Class C roads and 350 feet on Class A and B roads. Vertical curves shall be designed in accordance with AASHTO (American Association of State Highway and Transportation Officials) standards for stopping sight distance for sag and curves.
P. 
Horizontal design criteria. Where road lines deflect from each other within a block, the inside radius shall be not less than 100 feet. At road intersections, the property lines shall be on a curve with a radius of at least 25 feet.
Q. 
Specifications and details. All improvements shall be constructed in accordance with the Woodbridge Road Specifications on file in the Office of the Commission.
A. 
Land adjacent to the proposed subdivision which is not capable of satisfactory independent subdivision into lots of the size specified by the Zoning Regulations of the Town shall not be excluded by the subdivider nor shall there be created any fragment of a lot or remainder in the subdivision which has an area of less size then specified for lot dimensions in the Zoning Regulations of the Town.[1] Fragments and remainders of land must be incorporated into adjacent lots.
[1]
Editor's Note: See Ch. 495, Zoning Regulations.
B. 
No lot, regardless of size, which is rendered useless for building due to utility easements, rights-of-way, wetlands, water courses, topography or any other reason shall be shown as building lots on any subdivision. Such property shall be included as part of adjoining lots.
C. 
On lots located on the outside of sharp curves (120° or more) and cul-de-sacs the Commission may allow the frontage requirement to be applied at the building line instead of the street line.
D. 
On corner lots the lot frontage may be determined from the point of intersection of the two street lines.
E. 
Side lines of lots, insofar as practicable, shall be as close to right angle or radial to street lines as possible. Variations from this rule shall be made only where it is impractical to do otherwise.
F. 
Proposed development on the lots should consider the use of passive solar energy techniques.
All storm drainage improvements shall be constructed in accordance with the Woodbridge Road Specifications on file in the Office of the Commission. The storm drainage system proposed for a subdivision shall be designed by the applicant's engineer and shall be accompanied by a narrative report. The design shall take into account the total drainage area of which the subdivision is a part and the required pipe size(s) for the drainage system to serve the area. The construction of the drainage system to serve the proposed subdivision shall be the responsibility of the subdivider.
All subdivision improvements to be dedicated to the Town shall be inspected by the Board of Selectmen or such agent and at such times as may be designated by the Board of Selectmen in accordance with the Woodbridge Road Specifications on file in the Office of the Commission.
Monuments shall be placed at all lot corners, at angle points, and the points of curves in roads and at such intermediate points as may be necessary. The location of all monuments shall be indicated on the subdivision plan. They shall be installed by the subdivider and their accuracy certified by a licensed land surveyor. The monuments shall be made of concrete, and shall be 36 inches in length. The top shall be four inches square and a point cast into it. The base shall be six inches square. The monument shall be set with the top six inches above finished grade.
The developer must certify to the Commission through a licensed land surveyor that monuments have been installed in compliance with the subdivision plan. No bond release shall be made until this certification is received by the Commission.
Where a proposed road or storm drain joins a state highway or state drain, the applicant shall obtain a permit for such connection from the Department of Transportation and shall present a copy of such permit to the Commission with the application. The applicant shall have furnished the Department of Transportation with a copy of the proposed subdivision plan of improvements, and said copy, with appropriate notations by the Department of Transportation, shall accompany the permit.
