Property not required to be landscaped with a Site Plan Permit approval shall be required to be maintained.
1.18.035 REQUIRED BUFFER WIDTHS AND IMPROVEMENTS.
The table below defines the standards for minimum required buffer widths and improvements for adjacent land uses. Where the combination of land uses are not found in the table, the Land Use Authority Board (LUAB) shall then determine an appropriate buffering requirement. The LUAB may also approve alternative buffering requirements that may be more or less restrictive than the standards contained in the table when the LUAB determines that the alternative standard eliminates nuisance concerns. Required buffers may be crossed by driveways, utility lines, sidewalks, and trails. Permitted freestanding signs may be based in required buffers. Outdoor sales, displays, or storage shall not be permitted within a required buffer.
|REQUIRED BUFFER WIDTHS AND IMPROVEMENTS|
|LAND USE 1 ¹||LAND USE 2 ¹||REQUIRED BUFFER WIDTH ²||REQUIRED IMPROVEMENTS 3 4 5|

¹ Note: In such cases where a specific or multiple combinations of land uses is not found in the table the Land Use Authority Board shall then determine an appropriate required buffering widths and improvements.
² Note: Buffer widths are spaces of improved landscaped areas along property lines. Each zoning district establishes setbacks, which are the distance or amount of space between buildings and property lines. The LUAB may reduce buffer width when site plan shows improvements within the buffer or set-back area.
3 Note: Trees. Deciduous Trees shall have a minimum trunk size of two (2) inches in caliper measured at ground level when planted. Evergreen trees shall have a minimum size of five (5) feet in height when planted. The applicant may elect to use either deciduous or evergreen trees to meet this requirement. Trees may not be spaced more than forty (40) feet apart. See Chapter 8-700 of the Revised Tremonton City Ordinances for placing and planting trees in Park Strips.
4 Note: Walls or Fences. Where required, screening walls or fences shall not be less than six (6) feet in height and site obscuring, unless approved otherwise by the Land Use Authority Board as part of Site Plan review. Masonry is the suggested type of fence. See Title III General Public Works Construction Standards and Specifications Detail 15, 15A and 15B for fencing types. Such wall, fence, and landscaping shall be maintained in good condition with no advertising thereon. Automobile Sales lots are exempt from fencing requirements, see Section 1.17.045.

I. Additional Restrictions. Many of the Covenants, Conditions, and Restrictions (CC&R’s) recorded with property contain restrictions on fencing. Property owners shall refer to these standards prior to installation.
1.18.045 CLEAR VISION TRIANGLE.
Clear lines of sight shall be provided at intersections by delineating triangular areas adjacent to all intersections, within which no parking, building, structure, berming, or landscaping over three (3) feet in height above the street shall be permitted. Driveways are prohibited within the clear vision triangle of local streets unless there is no other feasible placement of a driveway on a lot. Clear Vision Triangles may not be required if an approved chain link or other non-sight obscuring fence is used. The size of the clear vision triangles shall be as follows:
A. Local Streets. At intersections of local streets the triangle shall be defined by drawing a line between two (2) points that are thirty (30) feet from the intersection. See Diagram 18.2 Clear Vision Triangle.
B. Driveways and Local Streets. At intersections of driveways (this includes private driveways) and local streets: the triangle shall be defined by drawing a line between two (2) points that are fifteen (15) feet from the intersection along the lot lines or driveways and thirty (30) feet on the street side.
C. Other Streets. Larger clear vision triangles may be required by the City Engineer where local streets enter arterial streets, major collector streets, or parkways.
