1. 
Where a floodway has been determined and delineated, no new construction, development, storage of materials or equipment, or encroachments of any kind shall be permitted (except "two-wire" fences) except where the effect of such construction, storage, or encroachment is fully offset by accompanying stream improvements which have been approved by all appropriate local and/or state authorities.
2. 
Where detailed information is available concerning the 100-year flood (elevations and profile information) and a floodway has not been delineated, new construction, development, uses and activities shall be allowed to occur within such flood prone area, provided that the applicant has documented that the proposed new construction, development, use, or activity, together with all other existing and anticipated development, uses, and activities, will not increase the water surface elevation of the 100-year flood more than one foot at any point, and that the proposed new construction, development, use, or activity shall be undertaken in compliance with the regulations of this and any other applicable codes, ordinances, and regulations.
3. 
Where detailed information is not available concerning the 100-year flood, (elevations and profile information), new constructions, development, uses and activities shall be allowed to occur anywhere within the flood-prone area, provided that they shall be undertaken in compliance with the requirements of this and any other applicable codes, ordinances, and regulations.
4. 
The lowest floor levels (including basements) in residential structures (including substantial improvements to existing structures) shall be constructed at an elevation of at least 1 1/2 feet above the 100-year flood elevation.
5. 
The lowest floor levels in nonresidential buildings (including substantial improvements to existing structures) shall be constructed on or above the level of the 100-year flood; provided, however, that they and their attendant utilities and sanitary facilities may be constructed below the level of the 100-year flood, if they are flood-proofed up to an elevation of at least 1 1/2 feet above the 100-year flood.
[Ord. No. 1-77, 2/23/1977; as amended by Ord. No. 4-85, 7/5/1985]

[Ord. No. 1-77, 2/23/1977; as amended by Ord. No. 4-85, 7/5/1985]
1. 
All buildings and structures shall be firmly anchored in accordance with accepted engineering practices to prevent flotation, thus reducing the threat to life and property and decreasing the possibility of the blockage of bridge openings and other restricted sections of the watercourse.
2. 
All air ducts, large pipes and storage tanks located at or below the first floor level shall be firmly anchored to prevent flotation.
[Ord. No. 1-77, 2/23/1977; as amended by Ord. No. 4-85, 7/5/1985]
1. 
Wood flooring used at or below the first floor level shall be installed to accommodate a lateral expansion of the flooring, perpendicular to the flooring grain, without incurring structural damage to the building.
2. 
Plywood used at or below the first floor level shall be of any "exterior" or "marine" grade and of a water resistant or waterproof variety.
3. 
Basement ceilings in nonresidential structures shall have sufficient wet strength and be so installed as to survive inundation.
4. 
Window frames, door frames, and door jambs used at or below the first floor level shall be made of metal.
[Ord. No. 1-77, 2/23/1977; as amended by Ord. No. 4-85, 7/5/1985]
1. 
All electric water heaters, electric furnaces, electric air conditioning and ventilating systems, and other critical electrical installations shall be permitted only at elevations of 1 1/2 feet or more above the 100-year flood elevation.
2. 
No electrical distribution panels shall be allowed at an elevation less than three feet above the level of the 100-year flood elevation.
3. 
Separate electrical circuits shall serve lower levels and shall be dropped from above.
[Ord. No. 1-77, 2/23/1977; as amended by Ord. No. 4-85, 7/5/1985]
1. 
Water heaters, furnaces and other critical mechanical installations shall be permitted only at elevations of 1 1/2 feet or more above the 100-year flood elevation.
2. 
No part of any on-site sewage disposal system shall be constructed within any flood-prone area.
3. 
Water supply systems and sanitary sewage systems shall be designed to preclude infiltration of floodwaters into the systems and discharges from the system into floodwaters.
4. 
All gas and oil supply systems shall be designed to preclude the infiltration of floodwaters into the systems and discharges from the systems into floodwaters. Additional provisions shall be made for the drainage of these systems in the event that floodwater infiltration occurs.
[Ord. No. 1-77, 2/23/1977; as amended by Ord. No. 4-85, 7/5/1985]
1. 
Adhesives used at or below the first floor level shall have a bonding strength that is unaffected by inundation.
2. 
Doors and all wood trim at or below the first floor level shall be sealed with a waterproof paint or similar product.
3. 
Paints or other finishes used at or below the first floor level shall be capable of surviving inundation.
