3. The private drive or right-of-way serving the property is paved with either concrete or asphalt at least twelve (12) feet in width if there are no more than two (2) lots served by the drive and at least twenty four (24) feet in width if more than two (2) lots are served by the drive. The private drive or right-of-way shall be designated on the Final Plat as a perpetual public utility and right-of-way easement.

4. A private drive or right-of-way shall not service more than four (4) lots and each deep lot shall have no more than one (1) single-family dwelling per lot.

5. A flag lot shall serve no more than one (1) building lot.

D. The City Engineer may waive or modify the requirement for a public utility easement under this section if the easement has not been recorded and the City Engineer determines that the public utility easement is not needed for existing or future utilities.

2.06.090 DITCHES, CANALS AND NATURAL WATERWAYS.

A. Anytime a ditch, whether irrigation, drainage or a canal is piped, the developer shall obtain from the person or entity operating the ditch or canal and the City Engineer, approval regarding the design, construction size and type of pipes, cleanout boxes, diversion boxes, grates etc. to be used. The irrigation system shall then be constructed and installed in accordance with the approved design.

A retaining wall exceeding four (4) feet in height is required to be designed and engineered by a licensed engineer; however, any wall in the rear yard shall not exceed eight (8) feet in height.

2. Construction of a retaining wall shall include a drainage plan, which provides for containment of run off water on site or drainage to a City approved location. Any person constructing a retaining wall that exceeds four (4) feet in height requiring engineering shall also be required to obtain a building permit prior to construction, which shall also include a stamped engineered plan for that wall at that location.

3. A person who constructs a retaining wall within a public utility easement shall be financially responsible for removal or reconstruction if that easement is needed per Utah Code 54-3-27. A typical lot in Tremonton may include a seven foot-six inch (7′-6″) minimum to fifteen (15) foot public utility easement entirely around the boundary of each lot. Any person constructing a retaining wall within a public utility easement where utilities do not exist shall install conduit or sleeve for future use.

4. Retaining walls shall not be permitted within public utility easements where a storm drain, culinary water line, pressurized irrigation line, or sewer line is installed.

D. Every lot intended for building construction shall have a minimum buildable area behind the front setback line of at least forty(40) percent of the minimum lot area required by the zone in which the lot is located, prior to any grading.

E. Any area within a subdivision, which has an average, slope of thirty one (31) percent or greater shall remain ungraded.

F. Any area within a subdivision that has an average percent of slope between twenty (20) percent and less than thirty one (31) percent may be graded, provided, however, the grading area shall be less than one half of the area of such slopes. Developer shall provide a slope analysis with shade areas according to slope to determine areas that may be graded.

G. Any fill material shall be prepared and compacted as specified in Section 1804 of the International Building Code. Developer shall provide a compaction test report to the City Engineer and Building Official.

H. Cut slopes shall be no steeper than one and one-half (1½) feet horizontal to one (1) foot vertical (1½:1).

I. Fill slopes shall be no steeper than two (2) feet horizontal to one (1) foot vertical (2:1).

K. Areas that have been graded shall be planted within one hundred-twenty (120) days after the completion of final grading with natural vegetation or materials approved by the City Engineer. If the City determines that the area is subject to erosion danger, then the developer shall plant actively growing sod with an appropriate irrigation system. If final grading is completed between October 15th and March 15th of the next year, then organic cover material shall be placed on the graded area to eliminate erosion until such time that the soil can be permanently planted.

L. Natural vegetation shall remain in areas where grading is not permitted, and additional vegetation may be required by the City in such areas. The City may also require additional landscaping in areas that were graded in order to supplement the natural vegetation and to prevent erosion and slope failures.

M. Surface water runoff drainage shall be designed and installed to prevent both on-site and off-site flooding and erosion. Such drainage design shall channel water runoff away from cut and fill slopes and away from all buildings.

N. Any buildable area or portion of a buildable area shall be no closer than thirty (30) feet to any man-made or natural drainage channel.
