Summary

Vallejo requires full compliance with its floodplain management chapter before any new construction, relocation, or substantial improvement of a structure within an area of special flood hazard. Municipal Code Section 7.98.080 makes noncompliance a public offense, and Section 7.98.120 requires a separate development permit for any new construction or development in a mapped flood hazard area.

No structure or land shall hereafter be newly constructed, located, or substantially improved by extension, conversion, or alteration without full compliance with the terms of this chapter and other applicable regulations. Violation of the requirements (including violations of conditions and safeguards established in connection with conditions) shall constitute a public offense punishable as provided in Section 1.12.010 of this Code. Nothing herein shall prevent the city council of the city of Vallejo or city manager (or his/her designees) from taking such lawful action as is necessary to prevent or remedy any violation. The city manager shall promulgate and implement an administrative rule to designate the city officers and employees responsible to enforce the requirements of this chapter, and in connection therewith, request concurrence from the district manager of the Vallejo Sanitation and Flood Control District in the provisions of said administrative rule relative to the officers and employees of the district designated for such purpose.
