All driveways shall comply with the respective standard engineering specifications adopted by the Public Works Director and the following:

(1) Residential Driveways.

(a) Driveway widths shall be measured at the curb flow line exclusive of the transitions. Where there is no curb line, the driveway width shall be measured at the points where the extension of the two outer edges of the driveway intersect the street right-of-way.

(b) Only one driveway shall be permitted for each lot unless otherwise provided herein.

(c) No single driveway shall be wider than 34 feet or 50 percent of the lot frontage, whichever is smaller.

(d) Circular driveways are only permitted on lots with 100 feet or more of frontage on the street that carries the lot address.

(e) The combined widths of all driveways creating a circular driveway must not exceed a total of 40 feet.

(f) Lots with double frontage may have a secondary driveway off the flanking or side street, but no more than 22 feet in width.

(g) No driveway shall be located closer than 25 feet to an intersection of two streets unless otherwise approved by the Public Works Director or designee.

(h) No driveway shall encase a water meter box or irrigation meter box.

(i) Driveways must conform to the provisions of PMC 25.165.100(1)(p).

(j) Driveways must be positioned to avoid interfering with fire hydrants, utility boxes and equipment. The cost of relocating any utilities to accommodate a driveway shall be borne by the permit holder.

(2) Commercial Driveways.

(a) Driveway widths shall be measured at the curb flow line, exclusive of the transitions.

(b) No single driveway may exceed 35 feet unless the Public Works Director or designee determines a greater width is necessary, based on one or more of the following considerations:

(i) Street classification;

(ii) Street speed limit;

(iii) Traffic volume and turning movements;

(iv) Number of parking spaces within the parking lot served by the driveway;

(v) Whether or not the proposed driveway will serve multiple businesses;

(vi) Safety of pedestrians and motorists;

(vii) Type of vehicles typically using the proposed driveway;

(viii) Shared driveway advantage.

(c) The location and number of driveways permitted to serve a commercial property will be determined by the Public Works Director or designee. The determination of the location and number of driveways shall be based upon the review criteria of subsection (2)(b) of this section as deemed necessary to promote safety to pedestrian users of the public ways, to preclude hazardous or congestive traffic movements, to maintain desirable traffic flow along the arterial corridors, or for any other reason related to public safety. The decision of the Public Works Director is final unless appealed to the Hearing Examiner in writing and stating the reasons therefor within 14 days of the Director’s decision.
