(A) The applicant shall furnish such of the following information as is deemed necessary by the Board for determining the suitability of the particular site for the proposed use:
(1) Four copies of plans drawn to scale showing the nature, location, dimensions, and elevation of the lot, existing or proposed structures, fill storage or materials, flood proofing measures, and the relationship of the above to the location of the channel.
(2) A typical valley cross-section showing the channel of the stream, elevation of land areas adjoining each side of the channel, cross-sectional areas to be occupied by the proposed development, and high water information.
(3) Plan (surface view) showing elevations or contours of the ground; pertinent structure, fill, or storage elevations; size, location, and spatial arrangement of all proposed and existing structures on the site; location and elevations of streets, water supply, sanitary facilities, photographs showing existing land uses, and vegetation upstream and downstream; soil types; and other pertinent information.
(4) Profile showing the slope of the bottom of the channel or flow line of the stream.
(5) Specifications for building construction and materials, flood proofing, filling, dredging, grading, channel improvement, storage of materials, water supply and sanitary facilities.
(6) Estimate the discharge of the regulatory flood consistent with applicable flood plain management rules.
(7) Calculation of water surface elevations based upon a hydraulic analysis of the capacity of the stream channel and over bank areas to convey the regulatory flood.
(8) Computation of the floodway required to convey this flood without any measurable increase in flood heights. Computations of increases in flood heights caused by any encroachment is to be based upon the reasonable assumption that there will be an equal degree of encroachment on both sides of the stream within that reach. Generally any increase in flood stages attributable to encroachments on the flood plain of any river or stream shall not exceed 0.5 feet in any one reach or for the cumulative effect of several reaches.
(B) Construction and use to be as provided in applications, plans, permits, and certificates of zoning compliance.
(1) Zoning permits, special issues permits or certificates of zoning compliance issued on the basis of approved plans and applications authorize only the use, arrangement, and construction set forth in these approved plans and applications and no other use, arrangement, and construction set forth in these approved plans and applications, and no other use, arrangement, or construction.
(2) The applicant shall submit certification by a registered professional engineer that the finished fill and building floor elevations, flood proofing, or other flood protection measures were accomplished in compliance with this zoning code.
