1. Widths. Minimum widths for each type of public street shall be as follows:
Type of Street | Right-of-Way Width | Cartway Width |
|---|
Collector street | 60 feet | 40 feet |
Local street | 50 feet | 36 feet |
A. Where a subdivision abuts or contains an existing street of inadequate width, sufficient additional width shall be required to meet the above standards.
B. Additional right-of-way and cartway widths may be required by the Borough to promote public safety and convenience when special conditions require it, and to provide parking space in areas of intensive use.
2. Alignment.
A. Changes in street direction shall be made by horizontal curves with minimum center-line radii as follows:
(2) Collector streets: 300 feet.
(3) Major traffic streets: 500 feet.
| Minimum radius curves shall be avoided, if possible. |
B. Except on minor streets, a tangent shall be required between curves; however, a long radius curve shall be preferred in all cases to a series of curves and tangents. Tangents of 100 feet shall be required between reverse curves.
C. Proper superelevation shall be required when curve radii are less than the following:
(1) Six hundred feet on major traffic streets.
(2) Three hundred feet on minor, collector and marginal access streets.
D. Clear-sight distances shall be maintained along the center line of streets as follows:
(1) Minor and collector streets: 200 feet.
(2) Major traffic streets: 500 feet.
3. Grades shall be subject to the decision of the Borough Engineer.
4. Intersections.
A. No more than two streets shall cross at the same point.
B. Street intersections shall be at right angles, wherever possible, and intersections of less than 70° (measured at the center lines) shall be permitted).
C. Intersecting streets shall not enter into a major traffic street at intervals of less than 1,000 feet (measured from center line to center line).
D. Streets entering the opposite sides of another street shall either be directly across from each other or offset by at least 200 feet from center line to center line.
E. Where the grade of any street at the approach to an intersection exceeds 7%, a leveling area shall be provided having not greater than 4% grade for a distance of 25 feet, measured from the nearest right-of-way line of the intersecting street.
F. Maximum grade within any intersection shall not exceed 1%, and approaches to an intersection shall follow a straight course for 100 feet.
G. Curb radii at intersections shall be according to the following schedule of minimum lengths:
(2) Collector streets: 25 feet.
| Where streets of different categories intersect, the requirements for the more-important one shall hold. |
H. The right-of-way radii at intersections shall be at least 15 feet.
I. At intersections, the street right-of-way line shall be parallel to the curbline.
J. At all intersections, a clear-sight triangle of 75 feet shall be required.
5. Drainage.
A. Storm drainage facilities shall be provided to permit unimpeded flow of natural watercourses, to drain all low points along streets and to intercept stormwater runoff along streets at intervals reasonably related to the extent and grade of the area drained.
B. Stormwater shall not be dumped on neighboring tracts in laying out subdivisions.
C. The slope of the crown of minor and collector streets shall be as directed by the Borough Engineer. Where drainage is provided in the center of the cartway, slopes shall also be as directed by the Borough Engineer.
D. Storm sewers, as required, shall be placed in front of the curb when located in a street right-of-way. When located in undedicated land, they shall be placed within an easement not less than 15 feet wide, as approved by the Borough Engineer. Open ditches shall be avoided.
E. Inlets and manhole covers and frames shall conform to Borough standards.
F. All stormwater design must conform with the Borough of Quakertown MS4 Stormwater Management Ordinance (Chapter
21A).
G. All stormwater design must conform with Part
8 of this chapter.
6. General Development Standards.
A. Street cuts shall be provided with side slopes no steeper than one vertical to one horizontal, and streets on fill shall be provided with side slopes no steeper than one vertical to 1 1/2 horizontal. Such slopes shall be suitably planted with perennial grasses or other vegetation to prevent gullying and erosion.
B. Sidewalks shall generally be required in residential and commercial areas. Sidewalks shall be located as required by the Borough in the street right-of-way, with grade and paving continuous across driveways.
C. Hedges, fences and walls or other obstructions shall not be placed or planted within the right-of-way of any street.
D. Curbing shall be provided for the full length of all streets.
E. Material and construction standards for streets, curbs and gutters, storm and sanitary sewers, and sidewalks shall conform to Borough specifications and be subject to inspection by appropriate Borough officials.
