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.

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
