Document title
City C Subdivision Regulations - Stormwater Peak Flow Requirements
Importance
high
Used by
Firm BWJ (design obligation), City Engineer J (compliance review), Firm IBM (independent verification)
Used in context
Establishes the binding performance standard that Firm BWJ's subdivision design was required to satisfy: post-development 25-year recurrence interval peak stormwater flows must not exceed pre-development conditions. IBM's independent review found this standard was not met.
Version
Current at time of subdivision approval
Source Evidence
Source text
City C's subdivision regulations require that post-development 25-year recurrence interval peak stormwater flows must be equal to or less than pre-development conditions
Text references
City C's subdivision regulations require that post-development 25-year recurrence interval peak stormwater flows must be equal to or less than pre-development conditions
Firm IBM found storm runoff flows to be substantially larger for the 25-year, two-hour storm event after the subdivision was completed
