On April 17, at 10am, Ventura City Fire personnel and units responded to multiple reports of a structure fire in the 500 block of Main St. in Downtown. The first arriving unit reported smoke coming from the second story of the two story residential-over-commercial structure. An aggressive, coordinated interior attack allowed knockdown of the main body of the fire within 16 minutes. The size of the fire, combined with the construction type of the building, required extensive overhaul and checking for extension into both the concealed spaces and all adjoining occupancies. Businesses below that were not involved with fire were impacted by water runoff.
