Any lane, way, opening, construction entrance or privately owned road entering upon any public road within the Borough of Glen Gardner, excepting field openings to nonresidential land used exclusively for farming purposes.
MODIFIED
An existing driveway is modified within the meaning of this chapter when it is paved, widened or narrowed, when its horizontal location or vertical elevation is changed or when drainage facilities are installed or replaced.
UPHILL DRIVEWAY
A driveway whose grade rises in elevation from the existing grade at the edge of the municipal roadway.
[Amended 9-4-1990 by Ord. No. 90-4; 10-19-2010 by Ord. No. 2010-8]
No driveway which connects with an existing or proposed Borough road may be constructed or modified unless the owner first obtains a driveway permit from the Borough Zoning Officer upon the approval of the Borough Engineer. The applicant for a permit shall pay the Borough an application fee of $50 upon application. In addition, the applicant shall deposit with the Borough an escrow deposit in amount of $700 to cover the estimated cost of professional review and inspection of the application by the Borough Engineer and other professionals. The escrow deposit shall be administered by the Chief Financial Officer in accordance with the procedures set forth in § 104-74 of the Land Use Chapter of this Code, and the Borough may require replenishment of such escrow in accordance with such procedures.
All driveways to be constructed or modified shall be done in accordance with the following minimum requirements:
A. 
The maximum number of driveway openings permitted from a commercial or industrial lot to any one road shall be limited as follows:
Length of Lot Frontage
(feet)
Permitted Number of Driveway Openings
150 or less
1
151 or more
2
B. 
Adjacent driveway openings. A minimum clear distance of 25 feet shall separate any two driveways (on the same premises or on adjoining lots) entering upon a single municipal roadway, as measured along the right-of-way line.
C. 
Drainage facilities. Each driveway shall be constructed with suitable and adequately designed draining facilities. Wherever possible, driveway drainage shall be directed into natural drainage channels. Driveway drainage may be connected with existing drainage facilities within the municipal roadway, provided that said connection does not interfere with existing drainage, or cause erosion or deposits of sediment in the municipal drainage system. Driveway drainage systems shall not discharge onto adjoining properties causing erosion or sediment damage or flooding and shall not discharge onto the paved or traveled portion of any public right-of-way.
D. 
Sight distance required.
(1) 
Exit driveways. Any exit driveway shall be designed in profile, grading and location to permit a minimum sight distance of 150 feet measured in each direction along the center line of the intersecting road. The sight distance measurement shall be from a sight point on the center line of the exit driveway 15 feet behind the curbline of the thoroughfare, or, if no curbline exists, a minimum of 30 feet from the center line of the intersecting road. A clear sight triangle shall be established connecting the "sight points" described above, and shall be graded and otherwise kept free of shrubbery, fences, structures, etc. in order to maintain clear vision between sight points.
(2) 
Entrance driveways. Any entrance driveway shall be located to permit a minimum sight distance of 150 feet, for left-turning vehicles, from the intersection of the driveway and roadway center lines.
(3) 
Dual-purpose driveways. A single driveway utilized for both exit and entrance purposes shall conform to the requirements of both Subsection D(1) and (2) above.
(4) 
Commercial or industrial driveways. For a commercial use as defined by Chapter 104, Land use, the above minimum sight distances shall be increased by 50%. For industrial uses, sight distances shall be increased by 100%.
E. 
Permitted slope at intersection. The portion of any driveway within the road right-of-way shall be constructed so that the grade at the right-of-way line is not less than three inches nor more than six inches above the edge of the existing pavement or traveled way.
All driveways constructed or modified shall intersect perpendicular to the existing road pavement or traveled way. Any curved or angular approach of the driveway for aesthetic or topographical reasons shall be accomplished outside of the road right-of-way, or beyond 25 feet from the center line of the existing pavement, whichever is greater.
To assure adequate access for motor vehicles, any vertical curve on a driveway shall be flat enough to prevent the dragging of any vehicle undercarriage. Vertical curves shall not exceed a three-and-one-fourth-inch crest or a two-inch depression in a ten-foot chord.
All driveways shall be designed and constructed to the width standards herein specified. Driveway width shall be the curb-face-to-curb-face dimension, or pavement edge-to-edge dimension where curbs are not required, and shall be measured at the road right-of-way line or at a point 25 feet from the center line of road, whichever is greater.
A. 
Single-family residential driveways shall have a minimum width of 12 feet, and may taper to a minimum width of 10 feet beyond the right-of-way line. Driveways shall be flared on each side as it touches the intersecting road pavement or traveled way. (See Figure 1 and Figure 2 for typical residential driveway intersection details.[1])

B. 
Multifamily, commercial and industrial driveway widths shall be designed to accommodate commercial vehicles and higher traffic volumes, but in no event shall exceed a maximum width of 35 feet.
No new driveway shall be constructed at a profile grade exceeding 15% at any point. If a proposed uphill driveway will exceed a profile grade of 8% anywhere within the first 200 feet, as measured from the road right-of-way line along the driveway center line, then that portion of the driveway which exceeds 8% within the first 200 feet shall be paved with a bituminous concrete, macadam or portland cement concrete surface.
A. 
All driveways shall be constructed and maintained at all times in such a manner as to prevent erosion of soil and materials from them and the land behind them. Water and silt shall be prevented from running onto and accumulating upon the traveled way of municipal roads, or filling up road gutters, catch basins, inlets or pipe drains with sediment or debris.
B. 
In the event that the construction of any particular driveway in the Borough of Glen Gardner is subject to the provisions of Chapter 104, Land Use, Article XXIV, Soil Erosion and Sediment Control, the standards contained in such ordinance shall apply whenever such standards are more stringent, detailed or comprehensive than the standards contained herein.
All driveways shall be constructed so as not to block or interfere with the drainage within gutters or along the existing road pavement or traveled way. Under no circumstances shall the driveway be allowed to extend beyond the edge of the existing ditch line at an elevation creating an uneven flow line in the gutter or ditch, or beyond the existing edge of pavement creating a hump or uneven driving surface.
A. 
Paved gutter. The construction of a properly sized dish-type gutter will be permitted, provided that the existing water flow will not be blocked, altered or changed in any manner.
B. 
Culvert or piping. The installation of a suitably sized reinforced concrete pipe or culvert will be required in the event that the existing flow line or ditch cannot be crossed with a shallow dish-type gutter. The size of the pipe or culvert required shall be determined by the Borough Road Supervisor or Engineer.
