Some local big-box stores are challenging their property assessments. Four prominent chains all filed mid-July challenges in state Supreme Court in an apparent attempt to lower their property taxes.

Walmart, a big part of the Route 60 business strip, wants its town of Pomfret assessment set at $475,000. It is currently $1.9 million.

Another sizable Route 60 establishment, this one in the town of Dunkirk, is going to court over its assessment. Home Depot wants the town to assess its property at $2.5 million. The assessment is currently $4,702,000.

Tractor Supply Co. is going up against the town of Westfield over two parcels at its 21 Nichols Ave. store. Tractor Supply wants the assessment to be just 10% of what the town has — it wants it at $161,000 instead of $1.61 million.

Dollar General is challenging the town of Chautauqua over the assessment of its store at 199 W. Lake Road. Assessed at $750,000, Dollar General wants it to be $187,500.

Here’s three more recent assessment challenges noticed by the OBSERVER:

— Main St. Fredonia Co. LLC is challenging Pomfret on four parcels in Fredonia, two on East Main Street and two on Clinton Avenue. The parcels border one another and are in and around the Dollar General plaza — but don’t appear to include the store.

Three of the parcels are assessed at less than $5,000 each and Main St. Fredonia Co. LLC wants those cut in half. The most valuable parcel, by far, currently holds a developmental disabilities services office that’s next to Dollar General. The assessment there is $356,810. An assessment of $85,550 is sought.

— Cockaigne Holdings wants a change to the assessment at 346 Central Avenue in Fredonia, a residential property located near the Dunkirk city line. The property was assessed by the town of Pomfret at $159,000, but Cockaigne Holdings wants it to be $88,000.

— The owner of a trailer park at 5772 Ellicott Road in the town of Portland, Jean Gerardi, wants the property assessment of $564,800 changed to $329,835.
