From December 1933 to December 1936 the Napa County Mosquito Abatement District (Napa MAD) was involved in numerous water management and reclamation projects that received both federal and state funding. The Civil Works Administration (C.W.A.), the State Emergency Relief Administration (S.E.R.A.) and the Federal Works Progress Administration (W.P.A.), were programs that provided funds and oversaw proposed projects throughout the state. Napa MAD submitted numerous projects to address levee erosion, drainage and flooding. The majority of the work was in the south county marsh areas, with more than 13,000 cubic yards of excavation, 20,000 feet of hand ditching, numerous culverts and tide gates, and hundreds of acres of discing having been completed. S.E.R.A. funding was severely curtailed during December 1936, as well as in future years, resulting in Napa MAD and the local citizenry trying to find other means to complete both those projects in progress and future proposed projects.

C.W.A. / S.E.R.A. Projects

Project #SLF1044-X (SLF-205)

May contain: plot
  • Located at Calistoga, in Northern Napa County
  • Number of men employed 21.
  • The breeding areas were swamp and marsh spots caused by seepage from mountains and overflow from numerous geysers in a 530-acre area.
  • This area was considered important because Calistoga was a summer-resort city and the many types of mosquitoes were a serious obstacle to tourist travel.
  • The plan of procedure was digging ditches, and filling stagnant pools by manual labor.

The Calistoga Federal Pest Mosquito Control Project was started February 9, 1934 with funds provided by the Federal Government. Notification of available funding was released during December of 1933 with the stipulation that proposals and work had to be completed within the next three months. Unfortunately, all projects and funding were cancelled before March of 1934 resulting in only part of the Calistoga project having been completed. Napa MAD shortly thereafter prepared documents for resubmission of the proposed work under the State Emergency Relief Administration (S.E.R.A.). The work was never completed due to two work releases that had not been signed by a Mr. Carlenzoli and a Mr. E. Rockstroh. This project was later resubmitted as part of a countywide general project during September of 1936. Unfortunately, S.E.R.A. funds were severely cut during December of 1936, leaving the project unfunded and incomplete.

Project #SLF-101

May contain: plot
  • Located at Buckli Station, Southwest of Napa
  • Number of men employed 43.
  • The breeding areas were cracked ground, dead sloughs and ponds in a 2060-acre area.
  • This area was considered one of the primary breeding areas in Napa County.
  • It affected the city of Napa, Napa State Hospital, Mare Island and the surrounding farm territory.
  • The plan of procedure was ditching, lowering tide gates, filling water holes and cracks in reclaimed land.
