Effective as of September 30, 2015 the Federal Emergency Management Agency (FEMA) modified its flood hazard determinations and revised its flood zone maps for Dowtown Martinez. Buildings located within a flood zone that are substantially improved are required to comply with the floodplain management development regulations of the City of Martinez (Chapter 15.30 of the Municipal Code).
There are only a few private commercial buildings in Dowtown Martinez that are not located within a FEMA flood zone. Both "The Press Building" at 610 Court Street and the "Sharkey Building" at 630 Court Street are two of these buildings - they are located outside of the flood areas, meaning that the floodplain management development regulations do not apply.
