The town's Grand List of all taxable properties grew about 1.3 percent over the previous year, according to figures released Friday by Assessor Paul Friia.
The net 2013 Grand List totals $9,940,413,732, Friia said, compared to $9,804,698,690 in 2012, Friia reported. The list represents the total assessed value of all taxable properties in town, including real estate, motor vehicles and personal property.
Motor vehicles and personal property are valued annually, while real estate properties are updated based on market values determined by the revaluation completed as of Oct. 1, 2010.
The growth of the town's property base was slightly slower than year-to-year rise of 1.5 percent recorded in 2012 from 2011.
However, there was growth in all three categories of the tax rolls last year.
The 1.25 percent increase in real estate is a result of new residential and commercial construction and renovations over the past year, and indicates the continued strength of the Westport market, Friia said.
Motor vehicles notched a 2.5 percent increase, while personal property record a 4 percent boost, reflecting what the assessor said is a continued increase in commercial business activity.
The 2013 Grand List subtotals are:
• Real estate, $9,324,118,980
• Motor vehicles, $319,602,814
• Personal property, $296,691,938
Those figures compare with 2012 figures of $9,208,096,610 for real estate; $311,509,693 for motor vehicles and $285,092,387 for personal property.
The new Grand List figures will be used by town officials in preparing the tax rate to finance the 2014-15 municipal budget that will adopted this spring.
Friia noted that the figures released Friday are subject to change pending the outcome of Board of Assessment Appeals hearings in March.
