The city of Laguna Beach community development department director
and designated persons are hereby appointed to administer, implement
and enforce this chapter by granting or denying floodplain development
building permits in accord with its provisions.
(Ord. 1576 § 1, 2013)
The duties and responsibilities of the floodplain administrator
shall include, but not be limited to, the following:
(A) Permit Review. Review all floodplain development building permits
to determine:
(1) Permit requirements of this chapter have been satisfied, including
determination of substantial improvement and substantial damage of
existing structures;
(2) All other required state and federal permits have been obtained;
(3) The site is reasonably safe from flooding over the expected life
of the development (minimum of seventy-five years);
(4) 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 Laguna Beach; and
(5) All letters of map revision (LOMRs) 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 (CLOMRs).
Approved CLOMRs allow construction of the proposed flood control project
and land preparation as specified in the "start of construction" definition.
(B) Development of Substantial Improvement and Substantial Damage Procedures.
(1) Using FEMA publication FEMA 213, "Answers to Questions About Substantially
Damaged Buildings," develop detailed procedures for identifying and
administering requirements for substantial improvement and substantial
damage.
(2) Assure procedures are coordinated with other departments/divisions
and implemented by staff.
(C) Review, Use and Development of Other Base Flood Data.
(1) When base flood elevation data have not been provided in accordance with Section
25.38.030 or the future flood elevation data have not been modified to reflect best available science related to sea level rise, the Floodplain Administrator shall obtain, review, and reasonably utilize any base flood elevation and floodway data available from a federal or state agency, or other source, in order to administer Sections
25.38.050 through
25.38.057.
(2) When the base flood elevation data have not been modified to reflect future sea level rise, the Floodplain Administrator shall develop a sea level rise adjusted base flood elevation, as defined in Section
25.38.020 of this chapter, in order to administer Section
25.38.041(A)(3).
Note: A base flood elevation shall be obtained using one of
two methods from the FEMA publication, FEMA 265, "Managing Floodplain
Development in Approximate Zone A Areas – A Guide for Obtaining
and Developing Base (100-year) Flood Elevations" dated July 1995.

(D) Notification of Other Agencies.
(1) Alteration or relocation of a watercourse:
(a) Notify adjacent communities and the California Department of Water
Resources prior to alteration or relocation;
(b) Submit evidence of such notification to the Federal Emergency Management
Agency; and
(c) Assure that the flood carrying capacity within the altered or relocated
portion of said watercourse is maintained.
(2) Base flood elevation changes due to physical alterations:
(a) Within six months of information becoming available or project completion,
whichever comes first, the floodplain administrator shall submit or
ensure that the permit applicant submits technical or scientific data
to FEMA for a letter of map revision (LOMR).
(b) All LOMRs 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 (CLOMRs). Approved CLOMRs allow
construction of the proposed flood control project and land preparation
as specified in the "start of construction" definition.
Such submissions 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.

(3) Changes in Corporate Boundaries. Notify FEMA in writing whenever
the corporate boundaries have been modified by annexation or other
means and include a copy of a map of the community clearly delineating
the new corporate limits.
(E) Documentation of Floodplain Development. Obtain and maintain for
public inspection and make available as needed the following:
(2) Certification required by Section
25.38.050(C)(2) (elevation or floodproofing of nonresidential structures);
(4) Certification of elevation required by Section 25.38.052(A)(3) (subdivisions
and other proposed development standards);
(5) Certification required by Section
25.38.056(B) (floodway encroachments);
(6) Information required by Section
25.38.057(F) (coastal construction standards); and
(7) Maintain a record of all variance actions, including justification
for their issuance, and report such variances issued in its biennial
report submitted to the Federal Emergency Management Agency.
(F) Map Determination. Make interpretations where needed, as to the exact location of the boundaries of the areas of special flood hazard, 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
25.38.043.
(G) Remedial Action. Take action to remedy violations of this chapter as specified in Section
25.38.032.
(H) Biennial Report. Complete and submit biennial report to FEMA.
(I) Planning. Assure community's general plan is consistent with floodplain
management objectives herein.
(J) Nonconversion of Enclosed Areas Below the Lowest Floor. To ensure
that the areas below the base flood elevation shall be used solely
for parking vehicles, limited storage or access to the building and
not be finished for use as human habitation without first becoming
fully compliant with the floodplain management ordinance in effect
at the time of conversion, the floodplain administrator shall:
(1) Determine which applicants for new construction and/or substantial
improvements have fully enclosed areas below the lowest floor that
are five feet or higher;
(2) Enter into a "nonconversion agreement for construction within flood
hazard areas" or equivalent with the city of Laguna Beach. The agreement
shall be recorded with the Orange County recorder as a deed restriction.
The nonconversion agreement shall be in a form acceptable to the floodplain
administrator and city attorney; and
(3) Have the authority to inspect any area of a structure below the base
flood elevation to ensure compliance upon prior notice of at least
seventy-two hours.
(Ord. 1576 § 1, 2013)
A floodplain development building permit shall be obtained before any construction or other development, including manufactured homes, within any area of special flood hazard established in Section
25.38.031. Application for a floodplain development building permit shall be made on forms furnished by the city of Laguna Beach. The floodplain development building permit is additional to any other required permit, including a coastal development permit. The applicant shall provide the following minimum information:
(A) Plans in duplicate, drawn to scale, showing:

25.38.050(C)(2) and detailed in FEMA Technical Bulletin TB 3-93;
(8) Expected life of development (minimum of seventy-five years); and
(9) The adjusted base flood elevation necessary to reflect sea level rise as specified in Section
