I. SITE PLANNING Fig. 14: Interior and perimeter landscaping reduce the visual affects of large paved parking areas. Interior landscaping should be increased as parking lots get larger. A single 42 space parking ZOL 30. When do parking lots become too big? Four to six spaces, is pedestrian and human in character, while over twelve cars becomes "car dominated territory." The critical number seems to be ten. This marks the breaking point between a human lot and a sea of cars. Small lots can be accomplished by breaking large parking areas into sections divided with landscape areas. Each section should serve not more than 10 to 12 cars. Landscape islands and areas should be located to protect cars as well as to break up seas of asphalt. 31. A landscaped area shall be placed at the end of each interior row in the parking area with no more than 10 stalls between the landscape areas. Parking area design should also incorporate the following: • All driveways onto public streets should be located a minimum of 50 feet from the intersection. • All maneuvering needs should be provided for entirely on-site. • All areas not necessary for vehicular maneuvering or parking should be landscaped. Landscape areas within parking lots should not be less than 5 feet in width and protected with curbing. An average 15 square feet of interior landscaped area per parking space for parking areas with more than 40 spaces should be provided as a general rule. The minimum 12 square feet per parking space is intended to be applied only in unusual situations where site constraints severely limit developable area or where superior site design effectively break up the effects of large paved areas and create a pedestrian friendly design. 9
