The assessed value of a 230-year-old graveyard on Nova Scotia's South Shore increased by 600 per cent this year because assessors have just discovered it's on the ocean, the local cemeteries committee says.

"The previous assessment of the Old Cemetery had shown it as a property 'without water value,'" Dan Sinclair, secretary of the Port Medway Cemeteries Committee, wrote in an email to CBC News.

Sinclair said he was contacted by Nova Scotia's Property Valuation Services Corporation after CBC reported the 2014 assessment went from $15,000 to $105,000.

Sinclair said a Property Valuation Services Corporation official told him Tuesday the assessors have increased the dollar value of a properties with "water value," which "caused the assessment to jump the extra $90,000."

Sinclair did not indicate how the assessors discovered only this year that the cemetery overlooks the ocean.

The cemetery is tax exempt but filed an appeal notice on Tuesday, fearing the assessment could lead to higher taxes for the several hundred people living in Port Medway.

Sinclair said if the assessment stands, the overall value of all properties in the area would be artificially inflated.

"Then the municipality can either maintain or decrease the mill rate and still increase their tax revenues because of the higher assessment total," he said.
