Drainage
projects and street improvement projects with significant storm drainage components
will be largely based on resident-reported data—that is how the city
knows where the problem areas are. The following is taken from the
current draft of the CIP: Storm Drainage Prioritization Weighting Factors (see Table 2.1 in the CIPPM): Capacity of Existing Storm Drainage System 38% Design Event System Adequacy (40%) Extreme Event System Adequacy (20%) Reported “Non-Structural” Flooding (40%)
Existence of Structural Flooding 38% Reported “Structural Flooding” (65%) Flood Insurance Claims (35%) Drainage Impacts to Mobility 24% Reported “Street Impassable” Flooding (50%) Reported Flooded Underpasses (50%) Thus for Drainage projects, self-reporting through 3-1-1
accounts for 63.90% of the prioritization weight (40% of 38% + 65% of 38% + 100%
of 24%) Direct link - Water Standing In Street Will Not Drain Direct link - Report Flooding General 311 online |
