In addition to relating streets to topography as recommended in Section 1137.01, streets should be designed according to the function served, the use of abutting land and standards of width, intersections, maximum grades and curvatures, as set forth in the following subsections.
(a) Major streets function primarily for the movement of fast traffic between points of heavy traffic generation. Where a subdivision adjoins a major street, the Commission shall require a plan wherein access drives do not cut onto a major street in order to protect the residential property from the movement of heavy traffic, to avoid traffic congestion and to minimize hazards to traffic. Such a plan shall provide for access drives to cut only onto a local street or streets.
(b) Local streets shall allow for access to each lot. The layout shall be related to the topography and natural features. The street pattern should be indirect and yet continuous and formed of straight, moderately curved, loop, angular or ell streets. There shall be an underlying systematic pattern, but gridiron and other rigid geometrical patterns shall be avoided. The street pattern shall limit the number of local streets intersecting with a major street in order to protect the residential property from the movement of heavy traffic and to minimize hazards to the traffic on the major street.
(c) All streets shall be designed to allow for safe and convenient access and circulation of police, fire and medical vehicles.
(d) Right-of-way widths for all streets shall not be less than sixty feet.
(e) Intersecting streets shall be provided so that no block shall be longer than 2400 feet. "Dead-end" streets shall terminate at a turning circle having an outside diameter of not less than 150 feet. All intersections at side lines of streets shall be provided with a turnout which has a radius of not less than thirty feet.
(f) Grades of streets in vertical alignment shall not exceed ten percent. Grades of streets which are curved or provide access in only one direction shall not exceed eight percent. Street grades shall be not less than one percent in order to provide adequate surface drainage. The rate of change of grade shall not exceed four percent per 100 feet of length.
(g) Street names shall be selected which will not duplicate or be confused with the names of existing streets within the zip code area of the Village irrespective of modifying terms such as street, avenue, boulevard, etc. Streets that are or will eventually be continuations of existing or platted streets shall be named the same as such streets. Street names shall be subject to the approval of the Commission.
