68.40.010 Establishment of development permit.

A development permit shall be obtained before any construction or other development begins within any area of special flood hazard established in CMC 68.30.020. Application for a development permit shall be made on forms furnished by the Floodplain Administrator and may include, but not be limited to: plans in duplicate drawn to scale showing the nature, location, dimensions, and elevation of the area in question; existing or proposed structures, fill, storage of materials, drainage facilities; and the location of the foregoing. Specifically, the following information is required:

A. Proposed elevation in relation to mean sea level of the lowest floor (including basement) of all structures – elevation of highest adjacent grade and proposed elevation of lowest floor of all structures; or

B. Proposed elevation in relation to mean sea level to which any nonresidential structure will be floodproofed, if required in CMC 68.50.010(C)(3); and

C. All appropriate certifications listed in CMC 68.40.030(D); and

D. Description of the extent to which any watercourse will be altered or relocated as a result of proposed development. (Ord. 2095 § 3 (Exh. A), 2019)

68.40.020 Designation of Floodplain Administrator.

The Community Development Director is hereby appointed to administer, implement, and enforce this title by granting or denying development permits in accord with its provisions. (Ord. 2095 § 3 (Exh. A), 2019)

68.40.030 Duties and responsibilities of Floodplain Administrator.

The duties and responsibilities of the Floodplain Administrator shall include, but not be limited to, the following:

A. Permit Review. Review all development permits to determine that:

1. Permit requirements of this title have been satisfied;

2. All other required State and Federal permits have been obtained;

3. The site is reasonably safe from flooding; and

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. For purposes of this title, “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 within the jurisdictional boundaries of the City of Coronado.

B. Review and Use of Any Other Base Flood Data. When base flood elevation data has not been provided in accordance with CMC 68.30.020, 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 Chapter 68.50 CMC. Any such information shall be submitted to the City Council for adoption.

C. Notification of Other Agencies. In alteration or relocation of a watercourse:

1. Notify adjacent communities and the Department of Water Resources prior to alteration or relocation;

2. Submit evidence of such notification to the Federal Insurance Administration, Federal Emergency Management Agency;

3. Assure that the flood carrying capacity within the altered or relocated portion of said watercourse is maintained;

4. Where base flood elevations change due to physical alterations: Within six months of information becoming available or project completion, whichever comes first, the Floodplain Administrator shall submit or assure that the permit applicant submits technical or scientific data to FEMA for a letter of map revision (LOMR);

5. In the case of flood control projects, all LOMRs shall be approved by FEMA prior to the issuance of building permits. Approved conditional letters of map revision (CLOMR) allow construction of the proposed flood control project and land preparation as specified in the “start of construction” definition, but not the issuance of a building permit.

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; and

6. Where there are 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.

D. Documentation of Floodplain Development. Obtain and maintain for public inspection and make available as needed the following:

1. Certification required by CMC 68.50.010(C)(1) (lowest floor elevations);

2. Certification required by CMC 68.50.010(C)(2) (elevation or floodproofing of nonresidential structures);

3. Certification required by CMC 68.50.010(C)(3) (wet floodproofing standard);

4. Certification of elevation required by CMC 68.50.030(B) (subdivision standards);

5. Certification of regulatory floodway encroachments;

6. Information required by CMC 68.50.060(F) (coastal construction standards).

E. Map Determinations. Make interpretations, where needed, as to the exact location of the boundaries of the areas of special flood hazard, 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 Chapter 68.60 CMC.

F. Remedial Action. Take action to remedy violations of this title as specified in CMC 68.30.030. (Ord. 2095 § 3 (Exh. A), 2019; Ord. 2010 § 2, 2010)

68.40.040 Appeals.

The City Council of the City of Coronado shall hear and decide appeals when it is alleged there is an error in any requirement, decision, or determination made by the Floodplain Administrator in the enforcement or administration of this title. (Ord. 2095 § 3 (Exh. A), 2019)
