Permit review.
Riverside Municipal Code § 16.18.045
in effect16.18.045 - Permit review.
The Floodplain Administrator or designee shall review all development permits to determine:
A. Permit requirements of this chapter have been satisfied, including determination of substantial improvement and substantial damage of existing structures;
B. All other required State and Federal permits have been obtained;
C. The site is reasonably safe from flooding;
D. The proposed development does not adversely affect the carrying capacity of areas where base flood elevations have been determined but a floodway has not been designated. This means that the cumulative effect of the proposed development when combined with all other existing and anticipated development will not increase the water surface elevation of the base flood more than one foot at any point within the City of Riverside; and
E. All Letters of Map Revision (LOMR's) for flood control projects are approved prior to the issuance of building permits. Building Permits must not be issued based on Conditional Letters of Map Revision (CLOMR's). Approved CLOMR's allow construction of the proposed flood control project and land preparation as specified in the "start of construction" definition.
F. No permit or approval for development in any area of special flood hazards will be granted until the Floodplain Administrator or designee has determined that the provisions of this chapter have been met. When the information required or the procedures involved in the processing of such application or permit is not sufficient to address the matters required by this chapter, such additional information as reasonably required by the Floodplain Administrator shall be filed by the applicant prior to the processing of the application. Such additional information shall include the following: proposed elevation in relation to mean sea level of the lowest floor (including basement) of all structures; proposed elevation in relation to mean sea level to which any structure will be floodproofed; all required certifications; and description of the extent to which any watercourse will be altered or relocated as a result of the proposed development.
