A.   Designation Of Floodplain Administrator And Development Permits:
1.   The senior engineer manager or other engineer as designated by the city engineer is hereby appointed to administer and implement this chapter by granting or denying development permit applications in accordance with its provisions.
2.   Development permit applications shall have the same meaning as land disturbance permit applications as defined in section 18-1-030. Throughout the remainder of this chapter, the term "land disturbance permit" may be used in place of the term "development permit."
B.   Duties And Responsibilities Of Floodplain Administrator: Duties and responsibilities of the floodplain administrator shall include, but not be limited to, the following:
1.   Maintaining and holding open for public inspection all records pertaining to the provisions of this chapter;
2.   Reviewing permit applications to determine whether proposed building sites, including the placement of manufactured homes, will be reasonably safe from flooding;
3.   Reviewing, approving or denying all applications for land disturbance permits required by adoption of this chapter and title 18;
4.   Reviewing permits for proposed development to assure that all necessary permits have been obtained from those federal, state or local governmental agencies, including section 404 of the federal Water Pollution Control Act amendments of 1972, 33 USC § 1334, from which prior approval is required;
5.   Making the necessary interpretation as to the exact location of the boundaries of the areas of special flood hazards where, for example, there appears to be a conflict between a mapped boundary and actual field conditions;
6.   Notifying, in riverine situations, adjacent communities, Salt Lake County flood control, Utah division of water rights stream alterations and the Utah national flood insurance program coordinator of the Utah department of public safety division of homeland security prior to any alteration or relocation of a watercourse, and submit evidence of such notification to the Federal Emergency Management Agency;
7.   Assuring that the flood carrying capacity within the altered or relocated portion of any watercourse is maintained;
8.   When base flood elevation data has not been provided in accordance with subsection 12-1-040B, "Basis For Establishing Areas Of Special Flood Hazard", of this chapter, obtaining, reviewing and reasonably utilizing any base flood elevation data and floodway data available from a federal, state or other source, in order to administer the provisions of sections 12-1-070, "General Standards"; 12-1-080, "Specific Standards"; and 12-1-090, "Floodways", of this chapter;
9.   When a regulatory floodway has not been designated, requiring that no new construction, substantial improvements, or other development including fill shall be permitted within zones A1-30 and AE on the city's FIRM, unless it is demonstrated 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 (1') at any point within the city; and
10.   Under the provisions of 44 CFR Chapter 1, Part 65.12 of the national flood insurance program regulations, approving certain development in zones A1-30, AE, AH, on the city's FIRM which increases the water surface elevation of the base flood by more than one foot (1'); provided, that the city first applies for a conditional FIRM revision through FEMA (conditional letter of map revision).
C.   Permit Issuance Procedures: A land disturbance permit shall be obtained before construction or development begins within any area of special flood hazard established in subsection 12-1-040B of this chapter. Application for a land disturbance permit shall be made according to title 9 or title 17 and may include, but not be limited to, plans in duplicate drawn to scale showing the nature, location, dimensions, and elevations of the proposed landscape alterations, existing or proposed structures, including the placement of manufactured homes, 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 new and substantially improved structures;
2   Elevation in relation to mean sea level to which any non-residential structure shall be floodproofed;
3.   Certification by a registered professional engineer or architect that the floodproofing methods for any non-residential structure meet the floodproofing criteria in subsection 12-1-080B of this chapter;
4.   A description of the extent to which any watercourses or natural drainage will be altered or relocated as a result of proposed development; and
5.   A full and complete set of final plans, specifications, certifications and computations in electronic format compatible with the city's systems and hard copy of two (2) sets of eleven inch by seventeen inch (11" x 17") plans, specifications, certifications, and computations.
D.   Except as otherwise specifically provided in title 10, no building, structure, or building service equipment shall be erected, constructed, enlarged, altered, repaired, moved, improved, removed, converted, or demolished unless a separate and appropriate building permit for each building, structure, or building service equipment is first obtained as outlined in 10-3-010 and applicable standards of this title.
E.   Approval And Endorsement: Upon issuance of the land disturbance permit, the floodplain administrator shall endorse in writing, or stamp "Approved" on all required sets of plans and specifications. The floodplain administrator shall retain the plans and specifications during the period of construction and as thereafter required in subsection B1 of this section. The floodplain administrator shall return one set of the approved plans and specifications to the applicant. The applicant shall retain the approved set of plans and specifications at the site covered by the land disturbance permit at all times during which the work authorized thereby is in progress. The remaining plan set and specifications shall be used for city inspection and related field reviews.
E.   Approval Or Denial Of A Land Disturbance Permit By Floodplain Administrator: The floodplain administrator shall, based upon all of the provisions of this chapter and title 18, approve or deny the land disturbance permit in accordance with the following relevant factors:
1.   The danger to life and property due to flooding or erosion damage;
2.   The susceptibility of the proposed facility and its contents to flood damage and the effect of such damage on the individual owner;
3.   The danger that materials may be swept onto other lands to the injury of others;
4.   The compatibility of the proposed use with existing and anticipated development;
5.   The safety of access to the property in times of flood for ordinary and emergency vehicles;
6.   The costs of providing governmental services during and after flood conditions, including maintenance and repair of streets and bridges, and public utilities and facilities such as sewer, gas, electrical and water systems;
7.   The expected heights, velocity, duration, rate of rise and sediment transport of the floodwaters and the effects of wave action, if applicable, expected at the site;
8.   The necessity to the facility of a waterfront location, where applicable;
9.   The availability of alternative locations, not subject to flooding or erosion damage, for the proposed use; and
10.   The relationship of the proposed use to the comprehensive plan for that area. (Ord. 914, 9-22-2009; amd. Ord. 1428, 4- -2020)
