The land is regulated by the city's La Cima Development Agreement and is split into two lots and a section of road.
The new San Marcos Fire Station No. 2 is located on the 4.31-acre Lot 1, which has a planned public and institutional zoning.
The 1.2-acre Lot 2 sits empty, and the developer is seeking a community commercial zoning classification. The developer does not have a plan for the lot yet, city staff said during the meeting.
A 1.52-acre section of Flint Ridge Road would also be annexed under the proposed ordinance.
The zoning and annexation requests will first go before the San Marcos Planning and Zoning Commission on April 13, and it will make a recommendation to council members.
City Council set the first reading of the annexation ordinance for May 4 with a final reading and vote scheduled for its May 18 meeting.
