Design Criteria

Design storm return periods (years)

10-year, 25-year, 50-year, 100-year

“The City of South Salt Lake requires 100 years 24 hours storm event for the new development/re-development hydrology calculations... Table 5-1 South Salt Lake City 24-hr Storm Event Intensity Rate... 10-year* 25-year* 50-year* 100-year”
Section 5.2 and Table 5-1, Pages 5-9 to 5-10

Water quality volume method

80th percentile storm volume using 0.6-inch precipitation depth (d80) with volumetric runoff coefficient (Reese or NRCS soil group method); V80 = RV × d80 × A.

“For new developments, the new MS4 permit requires 80th percentile storm precipitation for the total disturbed area... 80th Percentile: 0.6 inches... V80 = RV × d80 × A”
Sections 3.1 and 3.2, Pages 3-4 to 3-5

Peak flow calculation method(s)

Rational Method, NRCS Curve Number Method (TR-55)

“The City of South Salt Lake allows Rational Method and SCS Curve Number Method (NRCS TR-55 Hydrology Design Method) for the design of hydrology system.”
Section 5.1, Page 5-9
