The duties and responsibilities of the floodplain administrator shall include, but
not be limited to:
(a)
Permit Review.
(1)
Reviewing all development permits within areas of special flood hazard to determine
that the permit requirements of this chapter have been satisfied;
(2)
Determining that the site is reasonably safe from flooding; and
(3)
Determining that 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. For purposes of this chapter, "adversely affects" means that the cumulative
effect of the proposed development when combined with all other existing and anticipated
development will increase the water surface elevation of the base flood more than
one foot at any point.
(4)
Review proposed development to assure that all necessary permits have been received
from those governmental agencies from which approval is required by federal or state
law, including Section 404 of the Federal Water Pollution Control Act Amendments of
1972, 33 U.S.C. 1334.
(b)
Use of Other Base Flood Data. Obtaining, reviewing, and utilizing any base flood elevation
and floodway data available from a federal or state agency, or other source, in order
to administer sections 15A-13 and 15A-16 through 15A-25 when base flood elevation data has not been provided in accordance with section 15A-7.
(c)
Notification to Other Agencies.
(1)
Notifying adjacent communities and the California Department of Water Resources prior
to such alteration or relocation of a watercourse, and submitting evidence of such
notification to the Federal Insurance Administration, Federal Emergency Management
Agency, whenever a watercourse is to be altered or relocated.
(2)
Requiring that the flood carrying capacity of the altered or relocated portion of
said watercourse be maintained.
(3)
Base flood elevation changes due to physical alterations:
a.
Within six months of information becoming available or project completion, whichever
comes first, of a project that implements physical measures that affect the hydrogeologic
or hydraulic characteristics of a flooding source and thus result in the modification
of the existing regulatory floodway, the effective base flood elevations, or the special
flood hazard area the floodplain administrator shall submit or require that the permit
applicant submits technical or scientific data to FEMA for a Letter of Map Revision
(LOMR). Such submissions to FEMA are necessary so that upon confirmation of those
physical changes affecting flooding conditions, risk premium rates and floodplain
management requirements are based on current data.
b.
If a LOMR is requested prior to issuance of a building permit, the LOMR for the proposed
flood control project must be 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 may allow construction of the proposed flood control project and
land preparation as specified in the "start of construction" definition.
c.
Changes in County Boundaries. Notify FEMA in writing whenever the county boundaries
have been modified by annexation or other means and include a copy of a map of the
community clearly delineating the new county limits.
(d)
Public Inspection. Obtaining and maintaining for public inspection and making available
as needed:
(1)
The certification required by subsection 15A-16(c)(1) (floor elevations); and
(2)
The certification required by subsection 15A-16(c)(2) (elevations in areas of shallow flooding); and
(3)
The certification required by subsection 15A-16(c)(3)(C) (elevation or floodproofing of nonresidential structures); and
(4)
The certification required by subsection 15A-16(c)(4)(A) or 15A-16(c)(4)(B) (wet floodproofing standard);
(5)
The certification of elevation required by subsection 15A-18(b) (subdivision standards);
(6)
The certification required by subsection 15A-21(a) (floodway encroachments);
(7)
The information required by subsection 15A-22(f) (coastal construction standards).
(e)
Boundary Determination. Making interpretations where needed, as to the exact location
of the boundaries of the areas of special flood hazards (for example, where there
appears to be a conflict between a mapped boundary and actual field conditions). The
person contesting the location of the boundary shall be given a reasonable opportunity
to appeal the interpretation as provided in section 15A-24.
(f)
Enforcement. Taking action to remedy violations of this chapter as specified in section 15A-8 herein.
