If,
at the time of inspection, the stakes do not appear to be in the correct
place in relation to the setback lines of the building, the inspector,
at his discretion, may order the builder to furnish the city with
a certified letter from the surveyor, stating that the stakes meet
the above requirements.
(e)
Commercial
buildings constructed on corner lots shall and/or may be constructed
on the angular line created by connecting the 20-foot distance in

(1973 Code, sec. 8-25; 1991 Code,
sec. 9-31; 2007 Code, sec. 12-132)
(a)
Concrete
slab floors of structures proposed in areas of the city where natural
topography is significantly lower than the crown of the nearest street
or the top of the nearest sanitary sewer manhole shall be constructed
to a safe and adequate elevation above the natural ground. Factors
determining finished floor elevation shall include condition and elevation
of the nearest street, stormwater drainage conditions and highest
recorded stormwater level in the location of proposed construction.
Concrete slab floor elevations proposed in these limited areas of
the city shall be approved by the building official and the city manager.
(b)
Concrete
slab floors proposed in designated floodplains within the city shall
comply with provisions of the National Flood Insurance Program.
(c)
The
following conditions must be met for any building permit for construction
for residential use on land below the 500-year flood elevation:
(1)
The top of the subfloor of the lowest habitable floor must be elevated
to two feet above the 500-year flood elevation.
(2)
Construction shall use methods and practices that will minimize flood
damage and construction materials and utility equipment that are resistant
to flood damage. FEMA Bulletins 1-93, 2-93 and 3-93 or subsequent
revisions shall serve as the guideline for this requirement.
(3)
Unless dry-floodproofed, enclosed areas below the 500-year flood
elevation must be equipped with flood openings or vents capable of
equalizing water levels and hydrostatic loads. Covers of these openings
must not interfere with the equalization of water levels in the event
of a flood. A licensed architect or registered professional engineer
shall certify the flood openings.
(4)
Thermal insulation used below the 500-year flood elevation shall
be of a type that does not absorb water nor is buoyant.
(5)
Water heaters, furnaces, air conditioning systems, electrical distribution
panels and any other mechanical or electrical equipment must be elevated
to at least two feet above the 500-year flood elevation. Separate
electrical circuits shall serve any level below the 500-year flood
elevation and shall be dropped from above.
(6)
Basements are prohibited.
(7)
All air ducts, pipes, propane tanks and storage tanks located below
the 500-year flood elevation shall be anchored to prevent flotation.
Tanks and ducts shall be vented to at least two feet above the 500-year
flood elevation.
