A new audit of Marin County fiscal affairs gives the Civic Center a clean bill of health.

A review by accounting firm Gallina LLP gave the county “an unmodified clean opinion, with no significant deficiencies or material weaknesses noted,” according to Roy Given, the county’s director of finance.

Given said the audit turned up an error involving misclassification of a federal grant fund by health officials, but otherwise found no problem in the county’s books.

Given noted that in 2013, the national Government Finance Officers Association awarded Marin a certificate of achievement for excellence in financial reporting.

The county finance chief’s report came as county supervisors approved allocations of $3.9 million in reserve funding, designating half of it for a “one time” reserve fund for priority projects, and the other half for road and bridge repairs.

County Administrator Matthew Hymel noted the allocations mean that the county has earmarked more than $31 million for road repair over the past six years.

Hymel also reported that the “one time” reserve fund available for projects deemed important by county supervisors now stands at $7.1 million.
