1. Spacing. Driveways providing access to arterials must be spaced in accordance with the distances shown in Table 11.80.110.A-1.

Distances between adjacent one-way driveways with the inbound drive upstream from the outbound drive may be one-half the distance shown. Shared driveways are encouraged in order to meet the required separation. Driveways should align with existing driveways on the opposite side of the street.

2. Corner Clearance. To provide adequate corner clearance, the tangent curb length between the nearest edge of a driveway on an intersecting side street and an arterial street, or a driveway on an arterial street and an intersection with a cross street, will be 50 feet. Where the intersection is signalized or is planned for signalization, driveways will be limited to right-turn movements only if located within 125 feet on a collector and 250 feet on principal and minor arterials.

Where frontage is less than the required spacing, the driveway must be placed adjacent to the far property line in accordance with the property line spacing requirements specified in Section 11.80.110(A)(1).

Driveways providing access to arterial streets must be constructed in accordance with these requirements and the appropriate City standard plans. Distances for spacing and corner clearance will be measured between the BCR of the intersecting street and the nearest edge (wing) of the driveway.

3. Width. Driveways providing access from a residential property to an arterial must be 15 to 25 feet in width. Shared driveways serving two residential lots may not exceed 35 feet in width. When permitted, a commercial two-way driveway onto an arterial will be 25 to 40 feet in width.

4. Number of Driveways.

1. Spacing. Driveways providing access to a non-arterial streets must be spaced a minimum of 5 feet from the nearest property line and 10 feet from the nearest adjacent driveway, excepting when a property fronts on the bulb of a cul-de-sac. Where two driveways are permitted to provide access to a single parcel, a minimum separation of 30 feet is required between the two driveways.

2. Corner Clearance. To provide adequate corner clearance, the tangent curb length between the nearest edge of a driveway on a non-arterial street and the BCR on an intersecting non-arterial street is a minimum of 30 feet.

Where a corner lot is located at the intersection of a non-arterial street with an arterial street, the requirements specified in Section 11.80.110(A)(3) apply to the non-arterial street.

Where the frontage is less than the required spacing, the driveway must be placed adjacent to the far property line in accordance with the property line spacing requirements specified in Section 11.80.110(B)(1).

Driveways providing access to non-arterial streets must be constructed in accordance with these requirements and the appropriate City standard plans. Distances for spacing and corner clearance should be measured between the BCR of the intersecting street and the nearest edge (wing) of the driveway.

3. Width. Driveways providing access from a residential property to a non-arterial must comply with the width requirements specified in Table 11.80.110.B-1.

If a second driveway is permitted, the maximum width of the second driveway is 15 feet.

Driveways providing access from a commercial property to a non-arterial must comply with the width requirements specified in Table 11.80.110.B-2.

The minimum width for all service driveways is 20 feet at the bottom of the ramp. If more than one service driveway is desired for frontage up to 100 feet, the maximum width of each driveway is 20 feet, and not more than two such driveways will be permitted. The minimum frontage width for property on which two service driveways are constructed is 75 feet. If two service driveways are desired, they must be spaced a minimum of 20 feet apart.

4. Number of Driveways. A maximum of two driveways may be permitted for a residential or commercial lot. Shared or joint-use driveways are encouraged.

Requests for additional driveways beyond what is permitted herein must be justified by a traffic engineering study.

5. Additional Improvements. The installation of other improvements, e.g., turn lanes, acceleration lanes, deceleration lanes and traffic signals, may be required by the Director where they are found necessary on the basis of a traffic engineering study.

6. Temporary Driveway. A temporary driveway may be allowed when, because of conditions beyond the control of the developer, minimum driveway separation cannot be achieved at the time of application. The Director may approve a temporary driveway when an access plan shows future removal of the temporary driveway and a new driveway which will be installed and will meet the spacing standards shown above.

1. Medians and Channelization Standards. The purpose of medians and channelization is to manage vehicular traffic so that its flow is safe, efficient, and effective. In general, full-access intersections, signalized and non-signalized, on arterials will be permitted only with other county, state, and City arterial and residential streets. Circulation and access to adjacent land from such intersections will be provided in most cases by these permanent access points. However, if a median opening is requested, a traffic study must be performed under the requirements of Section 11.80.130. The proposed median opening or left-turn channelization may be approved only if the study shows:

2. Hierarchy of Access to Roadways. In situations where access to a property can be provided by multiple arterial or non-arterial streets, access will be provided by the street with the lowest functional classification, lowest volume, or as approved by the Director. (Ord. M-4026 §10, 2012)
