(a) General. Building permits are required in order to determine whether all new construction or substantial improvements are:
(1) Designed (or modified) and adequately anchored to prevent flotation, collapse, or lateral movement of the structure resulting from hydrodynamic and hydrostatic loads, including the effects of buoyancy.
(2) Constructed with materials and utility equipment resistant to flood damage.
(3) Constructed by methods and practices that minimize flood damage.
(4) Constructed with electrical, heating, ventilation, plumbing and air conditioning equipment and other service facilities that are designed and/or located so as to prevent water from entering or accumulating within the components during conditions of flooding.
(b) Basic Format. The basic format of the Building Permit shall include the following:
(1) Name and address of applicant.
(2) Name and address of owner of land on which proposed construction is to occur.
(3) Name and address of contractor.
(4) Site location.
(5) Brief description of proposed work and estimated cost.
(6) A plan of the site showing the exact size and location of the proposed construction as well as any existing buildings or structures.
(c) Elevation and Floodproofing Information, Depending on the type of structure involved, the following information shall also be included in the application for work within the Flood Plain Area:
(1) For structures to be elevated to the Base Flood Elevation:
A. A plan showing the size of the proposed structure and its relation to the lot where it is to be constructed.
B. A determination of elevations of the existing ground, proposed finished ground and lowest floor, certified by a Registered Professional Engineer, Surveyor or Architect.
C. Plans showing the method of elevating the proposed structure, including details of proposed fills, pile structures, retaining walls, foundations, erosion protection measures, etc. When required by the Permit Officer, these plans shall be prepared by a Registered Professional Engineer or Architect.
D. Plans showing the method used to protect utilities (including sewer, water, telephone, electric, gas, etc.) from flooding to the Base Flood Elevation at the building site.
(2) For structures to be floodproofed to the Base Flood Elevation (nonresidential structures only):
A. Plans showing details of all floodproofing measures, prepared by a Registered Professional Engineer or Architect, and showing the size of the proposed structure and its relation to the lot where it is to be constructed.
B. A determination of elevations of existing ground, proposed finished ground, lowest floor, and floodproofing limits; certified by a Registered Professional Engineer, Surveyor, or Architect.
C. A certificate prepared by the registered Professional Engineer or Architect who prepared the plans in subsection (2)A., above, that the structure in questions, together with attendant utility and sanitary facilities is designed so that:
1. Below the Base Flood elevation the structure is watertight with walls substantially impermeable to the passage of water.
2. The structure will withstand the hydrostatic, hydrodynamic, buoyant, impact, and other forces resulting from the flood depths, velocities, pressures, and other factors associated with the Base Flood.
(d) Site Plan Criteria. The owner or developer of any proposed subdivision, manufactured home park or subdivision or other development shall submit a site plan to the City Recorder which includes the following information:
(1) Name of engineer, surveyor, or other qualified person responsible for providing the information required in this section.
(2) A map showing the location of the proposed subdivision and/or development with respect to the municipality’s flood plain areas, proposed lots and sites, fills, flood or erosion protective facilities and areas subject to special deed restriction. In addition, it is required that all subdivision proposals and other proposed new developments greater than 50 lots or five (5) acres, whichever is the lesser, shall include base flood elevation data.
(3) Where the subdivision and/or development lies partially or completely in the flood plain areas, the plan map shall include detailed information giving the location and elevation of proposed roads, public utilities and building sites. All such maps shall also show contours at intervals of two (2) or five (5) feet depending upon the slope of the land and identify accurately the boundaries of the flood plain areas.
