§ 634. Nonresidential driveways.

Nonresidential driveways shall meet the following requirements. Driveways serving agricultural properties shall not require compliance with all of the requirements of this section; provided, however, that farms with poultry houses or livestock operations may be required by the public development director to meet any of these specifications or other alternatives for the safe ingress and egress of trucks and trailers in a manner that does not damage public improvements including roadway drainage structures.

(a)

Number. Along any county road, each lot shall be permitted no more than two points of vehicular access to each abutting public road; provided however, that lots with 150 feet of frontage or less shall have no more than one point of access to any one public street. The public development director shall determine whether the points of access may be unrestricted or will have to be designed for right-in, right-out traffic flow.

(b)

Two-way width: 24 feet minimum and 32 feet maximum.

(c)

One-way width: 12 feet minimum and 18 feet maximum.

(d)

Spacing from road intersection. Spacing of nonresidential driveways shall be as required by standard drawing T-10 (see article 23) for purposes of observing minimum required sight distance, unless specifically approved otherwise as part of final plat approval for a common development or per individual driveway permit.

(e)

Distance from property lines. Curb cuts may be located no closer than 20 feet from a property line, unless a common access driveway is approved by the public development director, in which case there is no setback from the common property line.

(f)

Locations. Driveways will be restricted to locations where movements into and out of them can occur in a safe and orderly manner, subject to the approval of the public development director.

(g)

Angle of intersection with street. Right angled (80 degrees to 100 degrees).

(h)

Driveway apron. Installation of an asphalt or concrete driveway apron may be required for any nonresidential driveway connecting to a county road. When a driveway apron is required, the minimum driveway radius for a shall be 15 feet for commercial and multi-family residential development and 25 feet for industrial development.

(i)

Slope and elevation. Any driveway entering on a roadway or street may be required to be sloped down from the street or roadway at a rate of one-half inch per one foot for a minimum of ten feet. In any case, the finished driveway surface within the right-of-way where it abuts the adjacent road must be no higher in elevation than the roadbed.

(j)

Drainage. As a condition of driveway approval, the public development director is authorized to require a driveway applicant to install a storm drainage culvert of a size as approved by the public development director in consultation with the county road superintendent (18-inch culvert typical where curb and gutter do not exist). All waters from driveways must enter onto the shoulders of adjacent roads and into the ditch or gutter. No water shall be permitted to enter onto the adjacent road surface or pavement.

(k)

Sidewalk transitions. Where a sidewalk is provided or planned, the driveway shall be designed and constructed with sidewalk transitions as appropriate.

(l)

Sight visibility clearance. With the exception of sign posts and other structures less than eight inches in diameter, structures and landscaping shall not exceed three feet in height within a triangle measuring 20 feet along the edge of a driveway and 20 feet along the street right-of-way line.

(m)

Alignment. Non-single-family residential driveways may be required to be aligned with existing or planned driveways on the opposite side of the road.

(n)

Additional location restriction. A driveway shall not be allowed along a right-of-way miter.

(o)

Additional travel lane. If the centerline of a driveway entrance on a major collector or arterial street is less than 400 feet from the centerline of an intersection, a continuous travel lane shall be constructed by the developer from the intersecting street to the driveway.
