Requirement to Maximize On-Street Parking Spaces. The placement of driveway openings, fire hydrants, street trees, lampposts, signs, and any other potential obstacles to the usability of on-street parking shall be arranged so as to maximize the number of usable on-street parking spaces immediately in front of, and adjacent to, the lot containing the activity. Where the lot containing the activity has frontage on more than one street, the number of usable on-street parking spaces shall be maximized along all frontages. The method for calculating the number of required usable on-street parking spaces shall be as set forth in Subsection B of this Section.

B.

Calculation Rules for Required On-Street Parking Spaces. The number of usable on-street parking spaces required by Subsection A. of this Section shall be determined as set forth in steps 1 through 4 below. All measurements shall be in feet.

1.

Measure the distance between the nearest parking obstructions on either side of the lot containing the activity.

2.

Subtract the width of the driveway opening or openings provided pursuant to Section 17.94.080, plus one and one-half (1½) feet on either side of each driveway opening.

3.

Subtract the width of any other parking obstructions immediately in front of the lot that presently exists or that would be constructed, located, or moved in conjunction with construction of the proposed driveway opening or openings.

4.

Divide the number obtained in step 3 by twenty (20) feet.

The number thus obtained, disregarding any fractional part thereof, shall be the number of usable on-street parking spaces required by Subsection A. of this Section.

C.

Definition of Parking Obstructions. For purposes of this Section, parking obstructions are any features, other than posted time limitations, which preclude or restrict the parallel on-street parking of an automobile, including but not limited to, the following:
