16.507 NATURAL HAZARD REDUCTION 16.507.01 PURPOSE AND APPLICABILITY The purpose of this Chapter is to implement General Plan policies and comply with applicable State requirements to protect public safety by identifying natural hazards and reducing their risk. More specifically, these regulations are intended to address the risks posed by wildfires, flooding, geotechnical hazards and seismic events, and projected sea level rise by: A. Maintaining up-to-date information identifying areas with high risk from wildfires, floods, earthquakes, and inundation from sea-level rise; B. Requiring development in areas at risk from natural hazards to consider the impacts of their proposal and incorporate measures that will reduce threats to public safety; C. Referring proposed plans and projects in risk areas to State and local environmental management agencies for review and comment.
16.507.02 WILDFIRE HAZARDS The following requirements apply to all development in areas that General Plan Map NBE-4 identifies as Moderate or High wildfire risk areas: A. Applications for development in Moderate or High wildfire risk areas shall be submitted to the Fire Prevention Department for review and recommendation of mitigation measures including specification of building and roof materials, firebreaks, fire resistant landscape materials, access roads to open as, internal fire protection systems and adequate water supply.
16.507.03 FLOOD HAZARDS All development proposed in areas identified by the Federal Insurance Administration’s “Flood Insurance Study for the City of Vallejo” shall comply with the following requirements: A. The Director shall refer applications to the Vallejo Flood and Wastewater District (VFWW) for review and comment and require applicants to revise projects as necessary in response to VFWW recommendations; B. Applicants proposing development, grading, and land modification activities that may adversely affect the local drainage system or create erosion may be required to submit engineering reports, subject to peer review at the applicants expense, recommending measures that should be incorporated to mitigate such impacts; C. New and modified structures in the 100year floodplain are required to comply with the City’s Flood Management Regulations including elevating building pads above flooding levels and other flood-proofing measures. D. The construction of permanent structures in designated floodways is prohibited. E. Development in areas identified as vulnerable to a projected 55-inch sea level rise by 2100 in General Plan Map NBE-6 or the City’s adopted Climate Action Plan, whichever is more restrictive is subject to environmental review for the purpose of assessing potential impacts of inundation and identifying measures to mitigate such effects.
B. All areas within 100 feet of combustible structures in the Moderate and High wildfire risk areas shall be kept clear of flammable vegetation.
