1. One-story detached accessory structures, provided the floor area does not exceed
120 square feet (11.15 m\
Section R109.1.3; change to read as follows:
R109.1.3 Floodplain inspections. For construction permitted in areas prone to
flooding as established by Table R301.2(1), upon placement of the lowest floor,
including basement, and prior to further vertical construction, the building official
may require submission of documentation, prepared and sealed by a registered design
professional, of the elevation of the lowest floor, including basement, required in
Section R323.
Section R112.2.1 &R 112.2.2 delete.
Rl12.2.1 Determination of substantial improvement in areas prone to flooding.
When the building official provides a finding required in Section R105.3.1.1, the
board of appeals shall determine whether the value of the proposed work
constitutes a substantial improvement. A substantial improvement means any
repair, reconstruction, rehabilitation, addition, or improvement of a building or
structure, the cost of which equals or exceeds 50 percent of the market value of
the building or structure before the improvement or repair is started. If the
building or structure has sustained substantial damage, all repairs are considered
substantial improvement regardless of the actual repair work performed. The term
does not include:
1. Improvements of a building or structure required to correct existing health,
sanitary or safety code violations identified by the building official and which are
the minimum necessary to assure safe living conditions; or
2. Any alteration of an historic building or structure provided that the alteration
will not preclude the continued designation as an historic building or structure for
the purpose of this exclusion, an historic building is:
Page 2
79740
2.1. Listed or preliminarily determined to be eligible for listing in the
National Register of Historic Places; or
2.2. Determined by the Secretary of the U.S. Department of Interior as
contributing to the historical significance of a registered historic district or
a district preliminarily determined to qualify as an historic district; or
2.3. Designated as historic under a state or local historic preservation
program that is approved by the Department of Interior.
Rl12.2.2Criteria for issuance of a variance for areas prone to flooding. A variance
shall only be issued upon:
1. A showing of good and sufficient cause that the unique characteristics of the
size, configuration or topography of the site render the elevation standards in
Section R323 in-appropriate.
2. A determination that failure to grant the variance would result in exceptional
hardship by rendering the lot undevelopable.
3. A determination that the granting of a variance will not result in increased flood
heights, additional threats to public safety, extraordinary public expense, nor
create nuisances, cause fraud on or victimization of the public, or conflict with
existing local laws or ordinances.
4. A determination that the variance is the minimum necessary to afford relief,
considering the flood hazard.
5. Submission to the applicant of written notice specifying the difference between
the design flood elevation and the elevation to which the building is to be built,
stating that the cost of flood insurance will be commensurate with the increased
risk resulting from the reduced floor elevation, and stating that construction below
the design flood elevation increases risks to life and property.
