8. Detention basins shall be constructed with emergency overflow spillways with a post development 100-year rainfall peak capacity.
9. Storm water drainage systems, including pipes, streets and gutter, must be designed to effectively convey flows to and from the detention basin for all storm events up to and including the 100-year rainfall event.
10. Flows from detention basin outlet structures and emergency overflow spillways shall be conveyed directly to a City designated storm drain system or street right-of-way without impacting other private property. This standard can be waived if a private property owner gives permission to receive the flow through deeded drainage easement.
11. All required improvements shall be designed and installed to City Engineering Standards.
12. Retention Basins
13. Retention basins shall be sized to retain at a minimum the 100-year, 24-hour post-development rainfall event. Retention basin sizing calculations must be included in a drainage study prepared by a licensed professional engineer in the state of Utah.
14. Retention basins shall be designed and constructed according to recommendations from a licensed profession engineer in the state of Utah specializing in geotechnical engineering. The retention basin design recommendations must be included in the soils report for the development.
15. Retention basins will not be allowed in highly susceptible soil or susceptible soil areas, or in other poor soils areas as recommended by the geotechnical engineer. Refer to the “Relative Hydrocompaction Susceptibility” map.
16. The side slopes of retention basins shall not be steeper than 3:1 (H:V).
17. The maximum depth of retention basins shall be three (3) feet plus one (1) foot of freeboard above the emergency overflow and a maximum water depth of three feet below the emergency overflow.
18. Fencing that will prevent entry is required around retention ponds if the maximum water depth below the emergency overflow is greater than 12 inches in depth. Fence minimum height is to be 42 inches.
19. Retention basins with a maximum water depth below the emergency overflow of 12 inches or less can be landscaped and used as open space for the development.
20. Retention basins shall be designed to drain out completely within 2 days (48 hours) from the end of the storm event. This is to be documented with a certified percolation test of the native sub-grade material and the material to be placed during construction. The percolation rate must be documented in the soils report.
21. Underground utilities (i.e., water lines, sewer lines, gas lines, power lines, telecommunication lines, etc.) shall not be allowed through the retention basin or within 5 feet of the pond side-slopes.
22. All retention ponds must be privately maintained and operated.
23. All required improvements shall be designed and installed to City Engineering Standards.
24. Sewage Disposal. Sewage disposal system shall be provided and must meet municipal and state codes and regulations for each lot in the subdivision. Said sewer systems shall be installed before the installation of road base, surfacing, curbs, gutters and sidewalks.
25. A comprehensive sewer study shall be performed for the development by a licensed Professional Engineer. The sewer study shall provide all necessary data required by this Ordinance or the City Engineer.
26. If the comprehensive sewer study defines additional or enhanced infrastructure outside the development area, the developer is required to build said infrastructure to mitigate the additional impact. (Outside of current impact fee plan/analysis)
27. All required improvements shall be designed and installed to City Engineering Standards.
28. Water Supply. A culinary water supply which must be approved by the City Engineer and the Utah Division of Water Quality shall be available to each lot in the subdivision and shall be provided in conformance with the standards and rules and regulations of the municipality. Where an approved public water supply is available, the subdivider shall install water mains and service lines or laterals from such mains to each lot within the subdivision prior to the installation of road base, surfacing, curbs and gutters and sidewalks. If an approved public water supply is not available, or the public water supply is not capable of providing sufficient culinary water to the development, the City Council may require the development to provide an additional, State approved, culinary water source. When the closest boundary of a development is within 1,320 feet of an active municipal irrigation source, the developer must provide irrigation to said development.
29. A comprehensive water model shall be performed for the development by a licensed Professional Engineer. The water model study shall provide all necessary data required by this Ordinance or the City Engineer.
30. If the comprehensive water study defines additional or enhanced infrastructure outside the development area, the developer is required to build said infrastructure to mitigate the additional impact. (Outside of current impact fee plan/analysis)
