The Central Okanagan's Emergency Operations Centre will be sending a massive flood prevention bill to the province.

Spokesman Joe Creron says the bill for the 2017 flood event that hit the Okanagan in early May will come in at about $20 million.

The final total could be slightly higher as bills come in for the clean up portion of the event.

Creron says they expect to get the full amount reimbursed from Emergency Management BC.

The $20-million bill is only for mitigation work throughout the region, and does not include damage done to public or private property.

Each jurisdiction is preparing the cost for damage done on public property within its boundaries.

The City of West Kelowna says it has already established damage to public property at $4.1 million.

Much of that was to parks and beaches along the waterfront.

There was also some damage in areas where sand was piled up for residents to use to fill sandbags.

The other municipalities within the Central Okanagan are in the process of determining the amount of damage in their respective areas.

While municipalities will receive the full cost of mitigation, the cost to repair and rebuild damaged infrastructure is paid out at 80 per cent of the entire bill by the province.
