(A) In any new subdivision the street layout shall conform to the arrangement, width and location indicated on any official plans or maps for the village. In areas for which such plans have not been completed, the streets shall be designed and located in proper relation to existing and proposed streets, to the topography, to such natural features as streams and tree growth, to public convenience and safety, and to the proposed use of land to be served by such streets.
(B) The proposed street layout shall be made according to good land planning practice for the type of development proposed, and shall be coordinated with the street system of the surrounding areas. All streets must provide for the continuation or approximate projection of principal streets in surrounding areas and provide reasonable means of ingress and egress for surrounding acreage tracts. All streets shall be located a minimum distance of 150 feet from the boundary of the village, provided, however, that subject to the approval of the Village Council this provision shall not apply to the dead end of a street where it intersects with the village boundary.
(C) Minimum street right-of-way width shall be as follows:
(1) Inside Municipal Jurisdiction Where Permitted by Resolution
Major thoroughfare 90 feet
Minor thoroughfare 70 feet
Local streets (residential) 60 feet
Frontage road 60 feet
Cul-de-sac 60 feet
Cul-de-sac (turnarounds) 100 feet
All other public rights-of-way 50 feet
(2) Subdivisions along existing streets of inadequate right- of-way to meet the minimum widths specified above. The entire right-of- way shall be provided where any part of a new subdivision is on both sides of an existing street, and one-half the required right-of-way measured from the center line of the existing street shall be provided where a new subdivision is located only on one side of an existing street.
(D) Where curbs and gutters are provided, the paving widths back- to-back of curbs shall be not less than the following:
Major thoroughfares 32 feet
Minor thoroughfares 32 feet
Local Streets (residential) 29 feet
Frontage roads 29 feet
Cul-de-sac 29 feet
Cul-de-sac (turnarounds) 80 feet
(E) Where curbs and gutters are not provided, the paving widths shall be not less than the following:
Minor thoroughfares 20 feet
Local streets (residential 20 feet
(F) Unless necessitated by exceptional topography and subject to the approval of the Planning Board, the grades shall be not more than 10% nor less than one-half of one percent on any street.
(1) Grades approaching intersections shall not exceed 5% for a distance of not less than 100 feet from the center line of the intersection.
(2) Street grades shall be established wherever practicable in such a manner as to avoid excessive grading, the promiscuous removal of ground cover and tree growth and general leveling of the topography.
(3) In the interest of public safety, no less than the minimum sight distance applicable shall be provided in every instance. Vertical curves that connect each change in grade shall be provided and calculated using the parameters listed below. (General practice calls for vertical curves to be multiples of 50 feet. Calculated lengths shall be rounded up in each case.)
Local Street | Minor Thoroughfare | Major Thoroughfare |
Local Street | Minor Thoroughfare | Major Thoroughfare | |
Design Speed, mph | 30 | 40 | 50 |
Stopping Sight Distance - | |||
i. Minimum Stopping Distance, Feet | 200 | 275 | 350 |
ii. Minimum K* Value For: | |||
a) Minimum Crest Vertical Curve | 28 | 55 | 85 |
b) Minimum SAG Vertical Curve | 35 | 55 | 75 |
Passing Sight Distance - | |||
i. Minimum Passing Distance, Feet (2 lane) | 1100 | 1500 | 1800 |
ii. Minimum K* Value for Crest Vertical Curve | 365 | 686 | 985 |
* is a coefficient by which the algebraic difference in grad may be multiplied to determine the length in feet of the vertical curve which will provide maximum sight distance. | |||
Sight distance provided for stopping vehicles at intersections should be in accordance with, "A Policy on Geometric Design of Rural Highways."
(G) Superelevation for shoulder section shall not exceed .08 feet/foot of width and for curb and gutter section shall not be less than 0.02 feet/foot of width nor more than .06 feet/foot of width.
(H) When a continuous street center lines deflects at any point by more than ten degrees, such center shall follow the area of a circle having a radius as follows:
Major thoroughfares 300 feet
Minor thoroughfares 200 feet
Local streets 100 feet

(I) A tangent at least 100 feet long shall be provided between reverse curves on all streets.
(J) Streets shall be laid out so as to intersect as nearly as possible at right angles and no street shall intersect any other street at less than 60 degrees.
(1) Street jogs with center line offsets of less than 150 feet shall be avoided.
(2) Intersections with a major thoroughfare (primary highway) or minor thoroughfare (major county road) shall be at least 800 feet apart.
(3) Property lines at street intersections shall be rounded with a minimum radius when required by the Planning Board.
(K) Permanent deadend streets or cul-de-sac shall be no longer than 600 feet and shall be provided at the closed end with a turnaround having an outside roadway diameter of at least 80 feet, and a street property line diameter of at least 100 feet.
(L) Street names for all subdivision plats shall be subject to the approval of the Village Council. New street names shall not duplicate or be similar to existing street names and existing street names shall be projected wherever possible.
(M) Where a tract of land to be subdivided adjoins a federal or state highway, the subdivider may be required to provide a frontage road parallel to the highway or reverse frontage on an interior street for the lots to be developed adjacent to the highway. If reverse frontage is required, then the subdivider shall be required to provide a ten-foot easement parallel and adjacent to the right-of-way of the highway. Such easement shall be restricted to the planting of trees or shrubs for screening purposes and shall be in addition to all other easements required by this ordinance.
(N) Where curbs and gutters are not installed, a minimum of 44 feet shall be left between drainage ditches along dedicated streets right-of-way.
(O) Drainage pipes, with a minimum diameter of 15 inches, shall be installed under driveways which cross drainage ditches. In some cases, a depression or swale may be substituted when the driveway is paved so that drainage is not obstructed, and approval is obtained from the Division of Highways.

(P) Except where curbs and gutters are installed, driveways shall be constructed so that surface water will not drain into the road or highway.
(Q) All unpaved areas of street rights-of-way shall be seeded and mulched according to Division of Highway specifications prior to being added to the highway system.
