Commissioners said they could use discretionary funds from the 1-cent sales tax to build a sidewalk on Mullikin Road from Furys Ferry Road to Hunter's Cove, near the Savannah River.
Scott Herring, the county's director of Construction and Maintenance Services, estimated the cost at $575,000.
The commission also approved a resolution to include a general obligation bond referendum for the construction of a natatorium and tennis courts on the ballot for the November general election.
Should voters approve it, the referendum would allow county officials to issue up to a $17 million bond, paid back with a property tax increase.
The commission approved a second resolution Tuesday to add a new 1-cent sales tax referendum to the November ballot.
Should it pass, officials expect the sales tax to raise about $180 million from 2011 to 2016.
