76-175. Parking lot landscaping requirements.

Interior parking lot landscaping. All interior parking lots shall incorporate and provide curbed tree planting spaces providing not less than seven feet at their least dimension and a minimum 50 square feet of land area per each tree planted. Trees shall be placed somewhat evenly, either symmetrically or asymmetrically, throughout the parking area. The number of trees required shall be based on a ratio of one tree for each six parking spaces, or fraction thereof. Small parking areas of less than 20 spaces may place the required trees next to the parking area, rather than within the lot proper. The minimum size of all parking lot trees, shall be 1 1/2 inches caliper at the time of planting. The following types of trees or similar types are considered to be suitable for parking lots and other intense urban conditions:

Frontage landscaping. Street landscaping shall be required in a linear order along any public right-of-way line of any street, road or highway in the required front yard setback in districts where parking is not permitted. One tree shall be planted for each 30 linear feet of the landscaping strip and shall be located within such required front yard setback.

Vision clearance. To ensure that landscape materials do not constitute a driving hazard, clear vision site triangles shall be established at all street intersections and at the intersection of site driveways and streets. See section 76-79. Internal parking lot landscaping improvements should be located to avoid blocking the vision of drivers within the parking lot.
