§ 22.54.020. Site Access and Driveway Requirements.
All projects that are subject to land use or construction permit approval shall be provided adequate vehicular and pedestrian access, as follows:
A.
Minimum site access. No land use or construction permit shall be approved for any site unless the site has legal access and all-weather physical access to a public road; except that installation of all-weather physical access improvements may be provided prior to final building inspection, or prior to occupancy where allowed by Section 19.04.042 (Occupancy or use of an incomplete structure), where such improvements do not currently exist.
B.
Site access location. The provisions of this Subsection apply only to land uses that are required to have six or more parking spaces. Land use permit approval shall not be granted to a proposed use unless at least one driveway serving the use is located on the type of street specified by this Section. These requirements are based on the traffic volume and turnover rate generated by a new land use, determined by the number of parking spaces required and the intensity of use of the parking lot (see Chapter 22.18 - Off-Street Parking Required, or Article 4 for a special use).
1.
Required street type for access. At least one vehicle access driveway shall be located on any street with a capacity equal to or greater than the minimum specified by the following table. These standards do not apply to a parking lot that is a principal use (see Section 22.30.630 - Vehicle Storage).
Number of Spaces in Parking Lot Required Access Location Based on Parking Lot Turnover (1)(2)
High Medium Low 6 - 20 Local Local Alley 21 - 40 Collector (3) Local Local 41 - 80 Collector Collector Local 81 +
Collector (4)Collector Local (5) Notes:
(1)
Expressed as the type of street (arterial, collector, local) on which a proposed use must be located. Actual access driveways may be located on a cross-street where the site abuts the required type of street.
(2)
Parking lot turnover is determined by Chapter 22.18 (Parking and Loading), for the specific land use.
(3)
For the purposes of this Section, collector streets include freeway frontage roads that extend between two collectors, between two freeway access points (which must include access and egress for both freeway directions), or a combination of the two situations.
(4)
At least one site access driveway on a collector shall be within 800 feet of an arterial, measured along the roadway.
(5)
At least one site access driveway on a local street shall be within 400 feet of a collector, measured along the roadway.
2.
Alternative street types for access. Driveway access locations other than those required by Subsection B.1 above are allowable subject to Minor Use Permit approval, provided that the Review Authority first finds that the alternate location will not result in traffic congestion or traffic volumes inappropriate or substantially detrimental to the site vicinity. Where a Conditional Use Permit is otherwise required, the approval can be granted by the review authority through the Conditional Use Permit subject to the same required finding.
C.
Driveway placement. A driveway from a street to a parking area with four or more parking spaces shall be located and designed as follows:
1.
Distance from street corner. Driveways shall be located a minimum of 50 feet from the nearest street intersection, as measured from the centerline of the driveway to the nearest travel lane of the intersecting street.
2.
Number of driveways. Driveways serving a single site shall be limited to two along the frontage of any street, except where additional driveways are authorized by Minor Use Permit. The centerline of such driveways shall be separated by a minimum of 30 feet.
3.
Distance from property line. Where a driveway intersects a street, the driveway shall be located a minimum of four feet from a side property line, except that the driveway transition may extend to within one foot of the property line, and except where adjoining lots use a shared driveway.
D.
Driveway design and construction. Proposed driveways shall be designed and constructed as follows. These requirements are in addition to any applicable provisions of Chapter 13.08 of this code (Encroachments).

Adjustments. An adjustment to the standards of Section 22.54.020.D or E. may be granted where proposed by the applicant and mitigated practices are approved by the fire inspection authority, where the mitigation provides for the ability to apply the same degree of accepted fire suppression strategies and tactics and fire fighter safety as these regulations overall, towards providing a key point of defense from an approaching fire or defense against encroaching fire or escaping structure fires.
1.
