In mid 1941, the Civil Aeronautics Authority (CM) was still considering the airport as an “auxiliary field” according to Earl Bender, airport manager. The plan included a 3500-foot runway and navigation and meteorology stations, but would require the acquisition of additional 35 acres of land surrounding the airport to make it a class 3 airport. In July, the County Supervisors agreed to the plan, and with the help of the City, acquired an additional 5 acres, with $7000 from City and County funds. Those developments cleared the way for the CM to propose the expenditure of roughly $30,000 for runway development field drainage, 51 foot beacon tower, field shed, 51 boundary lights and a 64 by 80 foot hangar to house aircraft, as well as a classroom, office, and workshop space. Work was started in October, 1941, but no details are available on the completion of any of the items.
