Orange County Water & Wastewater Multi-Jurisdictional Hazard Mitigation Plan 2024
hazard mitigation. By collaborating with other agencies, outreach will engage larger audiences across a variety of platforms. Evaluate and study the practicality of an alternate regulatory lab, in the case of failure at Michelson. Consider the feasibility of locating and certifying an alternative regulatory lab site at LAWRP. Conduct an inflow & infiltration study to determine where 50 year and 100 year flood waters would collect. Study outcomes should include the following: ·What assets, including the collections conveyance system, would be affected? ·What facilities or equipment would need rehabilitation or replacement after a 50 year or 100 year flood? How should that work be prioritized? ·What would be the cost of the necessary temporary equipment to get the service area up and running, during the replacement/rehabilitation project? ·How would these impacts on the wastewater system affect potable water operations? Will they contaminate storage wells? ·How would this affect IRWD's recycled water business? ·What measures could IRWD take to prevent or mitigate any of the identified damage? Designate alternative locations for residual dirt and fill storage, away from the Michelson Yard. Continue coordination with police and public safety agencies for IRWD-preferred response actions during localized flooding incidents, to prevent increased flood waters impacting IRWD facilities associated with the lifting of manhole covers. Evaluate and study critical facilities and facilities of concern that could benefit from protective retaining wall installation.
