D. Parking Lot Design Requirements. The following requirements shall apply to parking lots located in the B-3 zone: 1. The parking lot shall be separated from the public sidewalk by a landscape planter located outside of the public right-of-way which is a minimum of five feet wide (measured as specified in Section 35.060.A of this title) and contained within a planter bed raised a minimum of six inches above the abutting parking lot surface. Landscape areas shall be irrigated and maintained in accordance with Section 35.130. 2. The planter shall be planted with shrubs which are maintained at a minimum height of twenty-four inches and a maximum height of thirty inches above the abutting parking lot surface, spaced at five feet on center. Deciduous trees as specified by the planning director shall be planted in the planter spaced at not more than twenty feet on center. The spacing of trees may be modified by the planning director if the type of trees planted will be of a size which, at maturity, requires a greater spacing. 3. When a parking space which takes access from the alley is located behind a building and abuts the sidewalk, screening between the sidewalk and the off-street parking space may be provided in the form of a solid screen or wall not more than thirty inches above the surface of the parking area, in lieu of providing the landscaping required by subsection D.2 of this section. 4. Landscaping is not required in the interior of parking lots containing sixty or fewer parking spaces. For parking lots containing more than sixty parking spaces there shall be planted canopy -type trees in the interior of the parking lot at the rate of one tree per each twenty parking spaces. When this computation results in a fraction of one-half or greater, the fraction shall be rounded up to the next whole number. Tree wells shall be a minimum size of five foot square positioned so as not to eliminate parking spaces and built with raised six-inch curbs which act as wheel stops. 5. Parking lots shall be surfaced in accordance with the requirements of Section 34.080 of this title. Wheel stops shall be provided where needed to prevent damage to plant materials. 6. When the parking lot abuts an alley, access to the parking lot shall be taken from the alley. This requirement may be waived by the city engineer based upon extenuating topographic conditions or efficient traffic movement objectives. E. Off -Street Parking. 1. The required off-street parking spaces listed in Table #22-1 indicate the parking requirement for new buildings or additions to an existing building in the B-3 zone. As an alternative to the off-street parking standards contained in Table #22-1 for the B-3 zone, an applicant may propose an alternative parking standard which shall be reviewed by the planning director in accordance with Section 34.030. 2. Exceptions. a. Existing buildings which were built prior to zoning regulations or under a prior zoning code shall be permitted to be occupied without providing the additional off-street parking required by Table #22-1 for the B-3 zone. b. When an expansion of an existing building is proposed which adds the lesser of ten percent of the gross floor area that existed as of January 13, 1990, or one thousand square feet, no additional off-street parking shall be required for the new portion of the building.
