A. 
Development Permit Required. A development permit shall be obtained before construction or development begins within any area of special flood hazard established in LFPMC § 16.20.060. The permit shall be for all structures including manufactured homes, as set forth in Article II of this chapter, and for all development including fill and other activities, also as set forth in Article II of this chapter.
B. 
Application for Development Permit. Application for a development permit shall be made on forms furnished by the city and may include, but not be limited to: plans in duplicate drawn to scale showing the nature, location, dimensions and elevations 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:
1. 
Elevation in relation to mean sea level of the lowest floor (including basement) of all structures;
2. 
Elevation in relation to mean sea level to which any structure has been floodproofed;
3. 
Certification by a registered professional engineer or architect that the floodproofing methods for any nonresidential structure meet the floodproofing criteria in LFPMC § 16.20.420;
4. 
Description of the extent to which a watercourse will be altered or relocated as a result of proposed development; and
5. 
Any other such information that may be reasonably required by the floodplain administrator in order to review the application.
(Ord. 419 § 4.1, 1989; Ord. 937 § 1, 2005; Ord. 1208 § 1 (Exh. A), 2020)
The building inspector is appointed to administer, implement, and enforce this chapter by granting or denying development permit applications in accordance with its provisions. The floodplain administrator may delegate authority to implement these provisions.
(Ord. 419 § 4.2, 1989; Ord. 937 § 1, 2005; Ord. 1208 § 1 (Exh. A), 2020)
A. 
Permit Review. The floodplain administrator shall:
1. 
Review all development permits to determine that the permit requirements of this chapter have been satisfied;
2. 
Review all development permits to determine that all necessary permits have been obtained from those federal, state or local governmental agencies from which prior approval is required;
3. 
Review all development permits to ensure that the site is reasonably safe from flooding; and
4. 
Notify FEMA when annexations occur in the special flood hazard area.
B. 
Information to Be Obtained and Maintained.
1. 
Where base flood elevation data is provided through the flood insurance study or required as in this section, the floodplain administrator shall obtain and record the actual (as-built) elevation (in relation to mean sea level) of the lowest floor (including basement), of all new or substantially improved structures, and whether or not the structure contains a basement;
2. 
For all new or substantially improved floodproofed structures, the floodplain administrator shall:
a. 
Verify and record the actual elevation (in relation to mean sea level); and
b. 
Maintain the floodproofing certifications required in LFPMC § 16.20.290(B)(3);
3. 
The floodplain administrator shall maintain for public inspection all records pertaining to the provisions of this chapter;
4. 
The floodplain administrator shall maintain records of all variance actions, including justification for their issuance;
5. 
The floodplain administrator shall maintain improvement and damage calculations.
C. 
Alteration of Watercourses.
1. 
The floodplain administrator shall notify adjacent communities and the Washington State Department of Ecology prior to any alteration or relocation of a watercourse, and submit evidence of such notification to the Federal Insurance Administration; and
2. 
Shall require that maintenance is provided within the altered or relocated portion of the watercourse so that the flood-carrying capacity is not diminished.
D. 
Interpretation of FIRM Boundaries. The floodplain administrator shall 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 Article IV of this chapter.
(Ord. 419 § 4.3, 1989; Ord. 937 § 1, 2005; Ord. 1208 § 1 (Exh. A), 2020)
A. 
If a project will alter the BFE or boundaries of the SFHA, then the project proponent shall provide the community with engineering documentation and analysis regarding the proposed change. If the change to the BFE or boundaries of the SFHA would normally require a letter of map change, then the project proponent shall initiate, and receive approval of, a conditional letter of map revision (CLOMR) prior to approval of the development permit. The project shall be constructed in a manner consistent with the approved CLOMR.
B. 
If a CLOMR application is made, then the project proponent shall also supply the full CLOMR documentation package to the floodplain administrator to be attached to the floodplain development permit, including all required property owner notifications.
(Ord. 1208 § 1 (Exh. A), 2020)
