(Ord. 2009-2 § 2; Ord. 1104 § 1, 1984; Ord. 1040 § 1, 1981; 1964 code § 9.08.020).

12.08.050 Grades.
All grades of streets and curbs shall be a maximum of 10 percent. (Ord. 2009-2 § 5; 1964 code § 9.08.050).
12.08.060 Approach ramps.
A. Number and Width. The width of driveway and driveway approach aprons shall not exceed the following dimensions without approval of the public works director:
1. All driveways shall comply with any applicable Americans with Disabilities Act requirements and with the city of Grandview’s construction standards for curbs, driveways and commercial approaches.
2. For residential driveways, one single driveway up to 15 feet in width or one double driveway up to 25 feet in width shall be permitted to serve a single property. The public works director may approve more than one driveway or driveways with a width of more than 25 feet if traffic concerns warrant a circular driveway (double access) or if the residence has more than two garages.
3. For commercial driveways, no more than two driveways may serve a given property with no single driveway exceeding 35 feet in width; provided, that a raised island of not less than 20 feet of full height curb shall in all cases be provided between driveways serving one property frontage. The public works director may approve more than two driveways and driveways in excess of 30 feet when necessitated by the property, traffic flows and other relevant factors.
4. For industrial properties, driveways may be greater than two and wider than 35 feet and shall be approved by the public works director and as nearly as possible shall conform to the requirements of subsection B of this section.
5. “Property frontage,” as used in this section, includes property for driveway areas directly in front of the property under consideration and adjoining a public street, and such adjacent frontage which may be used for driving purposes by right of access easement or agreement with an adjacent property.
B. Placement with Respect to Property Lines and Intersecting Streets.
1. Driveways shall be located as far away from intersections with public streets and other private driveways as practicable.
2. Driveways, including end slopes, shall be located with the limits of the property lines extended to the street so that no driveway or approach to a driveway shall encroach in front of an adjacent property.
3. Driveways, including end slopes, shall not encroach into curb returns at street intersections.
4. Driveways located within five feet of an alley intersection may be merged with the alley opening width such that the total driving plus alley opening width shall not exceed 40 feet with the approval of the city’s public works director.
C. Angle of Entry. Driveways shall be constructed such that driveway approaches are as close as practicable to 90 degrees to the public street. In no case shall the angle of intersection be less than 60 degrees.
D. Vertical Alignment. Driveways shall be constructed with a maximum gradient of 15 percent and shall have a relatively level landing area (maximum gradient of two percent) of minimum 20-foot length adjacent to the back of curb or back of sidewalk where sidewalk exists.
E. Other Considerations.
1. Driveways shall be located to provide adequate sight distances where driveways access public streets. The following minimum sight distances are published in the latest edition of “A Policy on Geometric Design of Highways and Streets,” by the American Association of State Highways and Transportation.

(a) Corner sight distances measured from a point on the minor road at least 15 feet from the edge of the major road pavement and measured from a height of eye at 3.50 feet on the minor road to a height of object at 4.25 feet on the major road.
(b) At 60 miles per hour, stopping sight distance governs.
2. Driveways and the use of driveways shall not restrict the use of sidewalks adjacent to the property including handicap access ramps.
3. Driveways shall be located and constructed in such a way that the access into the property will be complete and will not cause the blocking of any sidewalk or public street.
4. New driveway locations shall be coordinated with other existing or planned driveway locations on the opposite side of the public street to be directly opposite the existing or planned driveways as practicable, and to avoid closely spaced offset driveway intersections. The objective is to minimize traffic and pedestrian conflict points.
5. There may be property land uses and locations where driveway location and design merit special consideration, including detailed traffic engineering analyses by the property owner and/or the city. These traffic engineering analyses may recommend requirements of greater setbacks from intersections, driveways with only right turn in and/or only right turn out movements permitted, median barriers to prevent left turns, etc. (Ord. 2009-2 § 6; Ord. 1643 § 1, 2002; Ord. 1475 § 1, 1996; Ord. 1454 § 1, 1996; 1964 code § 9.08.060).
12.08.070 Deferral of compliance until start of building construction.
Compliance with the provisions of this chapter may be deferred by written approval of the city council, provided no building permit for construction contiguous to a street hereafter platted, dedicated or resurfaced shall be issued or be valid for construction of any improvement where the street, curb and gutter adjoining the construction fails to comply with this chapter. No street improvements, curbs or gutters shall be installed which are not continuous and uninterrupted. The city council shall, by agreement with the builder or owner, fix a bond or other security for compliance with the provisions of this chapter as it deems advisable in each instance; each such approval shall be subject to review by the full council in regular session. (Ord. 2009-2 § 7; 1964 code § 9.08.070).
12.08.075 Basketball hoops or other items prohibited in street rights-of-way.
No basketball hoops, poles, stands or bases to support such hoops, either portable or permanently affixed, or any other items shall be located in or over city street rights-of-way. Upon finding such items in the public right-of-way, the city may remove such items and place them on the owner’s property with a violation notice attached. If said items are placed back on the city right-of-way, they may be removed by the city and, if unclaimed after five days, disposed of. (Ord. 2009-2 § 8; Ord. 1674 § 1, 2004).
12.08.080 Storm drainage.
Storm drainage shall comply with GMC 16.28.050. (Ord. 2009-2 § 11).
12.08.090 Sidewalks.
Sidewalks shall comply with GMC 16.28.060 and shall not be less than five feet for residential streets and seven feet for arterial streets. (Ord. 2009-2 § 12).
12.08.100 Street signs and traffic control.
Street signs and traffic controls shall comply with GMC 16.28.070. (Ord. 2009-2 § 13).
12.08.110 Civil action to enforce compliance.
The criminal penalties provided in GMC 12.08.120 will not be construed to prohibit a civil action. (Ord. 2009-2 § 9; 1964 code § 9.08.090. Formerly 12.08.080).
12.08.120 Violation – Penalty.
Any person, persons, or corporation found guilty of a violation of this chapter shall be subject to a fine not in excess of $1,000 and be confined in the city jail not to exceed 90 days, or both such fine and punishment. (Ord. 2009-2 § 10; 1964 code § 9.08.080. Formerly 12.08.090).
