Landscaping. All new development and redevelopment areas shall be landscaped with trees, ornamental shrubs, and green areas to provide visual buffering, and to enhance the entryway to the community created by the historic Route 66, a National Scenic Byway, that is scenic and welcoming. Landscaping standards in this district are as follow:
(1)
Landscape maintenance. The property owner is responsible for maintaining a landscape plan as originally approved and for the replacement of plant materials that have died, been damaged, or removed, for a period of five years after issuance of a certificate of occupancy or project completion.
(2)
Buffer.
(a)
A fifty-foot-wide buffer outside the ODOT right-of-way and with the required building setback along road frontage is required.
(b)
Planting. Planting is required to screen industrial activities and parking areas from Historic Route 66. If the grade of the site, or other condition, prevents the buffer from accomplishing this purpose, then the minimum requirements may be modified. Minimum requirements include:
[1]
Canopy trees: planted at a ratio of five trees for every 100 feet of frontage.
[2]
Understory trees: planted at a ratio of three trees for every 100 feet of frontage.
[3]
Shrubs: 12 shrubs for every 100 feet of frontage are required.
(3)
Berms. Planting requirements may be reduced by 50% if berms are constructed to provide buffering and screening. Berms shall vary in height and width and must be planted with native drought-tolerant plants. Berms are to be constructed and planted as follows:
(a)
Construction of an earthen berm requires a permit from the City. The permit application shall be signed by the owner and accompanied by a site plan indicating the exact location of the berm, the width, height and length of the berm, existing land contours and proposed contours.
(b)
The height of the berm shall not exceed 12 feet, and the slope of the berm shall not exceed one foot of vertical rise per three feet of horizontal distance (a maximum slope of 3:1).
(c)
Construction of the berm shall comply with applicable portions of the zoning ordinance dealing with stormwater runoff and, if located in a floodplain, shall comply with the provisions contained in the flood damage prevention ordinance.[1]
(d)
Berms adjacent to paved surfaces must be graded to capture all irrigation runoff or to convey it to an appropriate stormwater management feature.
(e)
The berm shall be landscaped; its landscaping shall be maintained by the property owner and shall comply with the provisions of Subsection A(3)(e)[1] through [5] below:
[1]
Grass or ground cover shall be planted on the berm. Proper siltation control shall be effected until such grass or ground cover is established.
[2]
Trees or shrubs shall be planted on the berm. At least 1/2 of the plant material shall be evergreen trees or shrubs. Evergreen trees shall be a minimum of six feet in height, and deciduous trees shall be not less than two inches in diameter measured one foot above the ground when planted.
[3]
All plant material shall be maintained by mowing, trimming, and removal of trash on a regular basis. Dead plant material shall be removed and replaced.
[4]
The construction, maintenance, and landscaping of a berm shall not unreasonably interfere with traffic sight lines on an adjacent street or highway.
(4)
Fences and walls.
(a)
If a fence or wall is constructed in the buffer, the minimum planting requirements may be reduced to:
[1]
Canopy trees: planted at a ratio of four trees for every 100 feet of frontage.
[2]
Understory trees: planted at a ratio of two trees for every 100 feet of frontage.
(b)
Height. Fences and walls shall be a minimum of five feet and no taller than eight feet.
