(A) Streets shall be completed to grades shown on the construction plans drawn by the subdivider’s professional engineer and approved by the Plan Commission.
(B) Intersections shall be designated with a flat grade wherever practical. In hilly or rolling areas, at the approach to an intersection, a leveling area shall be provided having not greater than a 2% grade at a distance of 100 feet, measured from the nearest right-of-way line of the intersecting street.
(C) At intersections of streets or alleys, property line corners shall be rounded by minimal arcs as follows: Arterial and all streets in commercial and industrial subdivisions shall have a minimum curb return radius of 35 feet. Collector streets shall have a minimum curb radius of 30 feet. Local streets shall have a minimum curb return radius of 25 feet.
(D) If the smaller angle of intersection of two streets is less than 75 degrees, the radius of the arc at the intersection of property lines shall be increased as deemed advisable by the Commission.
(E) Horizontal visibility and vertical visibility on all streets must be maintained along the center line as follows:
(1) Principal and minor arterial streets - 350 feet.
(2) Collector streets - 300 feet.
(3) Local streets - 250 feet.
(F) Curvature measure along the center line shall have a minimum radius as follows:
(1) Principal arterial streets - determined by design speed standards.
(2) Minor arterial streets - determined by design speed standards.
(3) Collector streets - 250 feet.
(4) Local streets - 200 feet .
(G) Between reversed curves there shall be a minimum tangent distance as follows:
(1) Principal and minor arterial streets - 250 feet.
(2) Collector streets - 200 feet.
(3) Local streets - 50 feet.
(H) Maximum/minimum grades for streets shall be as follows:
(1) Principal and minor arterial streets - not greater than 4%.
(2) Collector streets - not greater than 5%.
(3) Local streets - not greater than 8%.
(4) Minimum grade for all streets is 0.5%.
(I) Before any performance bond covering a street installation is released, the Plan Commission, Town Council, or Town Engineer may request that core borings of the street be done at the subdivider’s expense. Cores shall be reviewed by an independent testing laboratory or registered engineer for analysis.
(J) A developer may request permission of the Plan Commission to delay the installation of the one-inch surface layer of asphalt until the binder layer of asphalt has had a sufficient time period to prove its durability under the stress of heavy construction traffic. The developer may be required to submit a separate performance bond to cover the cost of the installation of the one-inch surface layer of asphalt, or at the time of town adoption, or at 80% occupancy.
(K) Design requirements of street pavements to conform with the specifications of the Allen County Highway Department, unless otherwise modified by this chapter.
(L) Dimensional requirements of street pavements.
Street Type | Street Width (Feet) | Dedicated Right-of-Way Width (Feet) |
Major Arterial | 48 | 90 |
Minor Arterial | 44 | 80 |
Major Collector | 38 | 70 |
Minor Collector | 34 | 60 |
Local | 27 | 50 |
Street width is measured from back to back of the curb and gutter located on each side of the street. If no curb and gutter, it would be to edge of the street. | ||
