“Fraud and victimization,” as related to Chapter 16.90 PMC, Variances, means that the variance granted must not cause fraud on or victimization of the public. In examining this requirement, the City of Poway will consider the fact that every newly constructed building adds to government responsibilities and remains a part of the community for 50 to 100 years. Buildings that are permitted to be constructed below the base flood elevation are subject during all those years to increased risk of damage from floods, while future owners of the property and the community as a whole are subject to all the costs, inconvenience, danger, and suffering that those increased flood damages bring. In addition, future owners may purchase the property, unaware that it is subject to potential flood damage, and can be insured only at very high flood insurance rates. (Ord. 599 § 2, 2004)

16.82.310 Hardship.

“Hardship,” as related to Chapter 16.90 PMC, Variances, means the exceptional hardship that would result from a failure to grant the requested variance. The City of Poway requires that the variance be exceptional, unusual, and peculiar to the property involved. Mere economic or financial hardship alone is not exceptional. Inconvenience, aesthetic considerations, physical handicaps, personal preferences, or the disapproval of one’s neighbors likewise cannot, as a rule, qualify as an exceptional hardship. All of these problems can be resolved through other means without granting a variance, even if the alternative is more expensive, or requires the property owner to build elsewhere or put the parcel to a different use than originally intended. (Ord. 599 § 2, 2004)

(Ord. 599 § 2, 2004)

16.82.340 Levee.

“Levee” means a manmade structure, usually an earthen embankment, designed and constructed in accordance with sound engineering practices to contain, control or divert the flow of water so as to provide protection from temporary flooding. (Ord. 599 § 2, 2004)

“Levee system” means a flood protection system which consists of a levee, or levees, and associated structures, such as closure and drainage devices, which are constructed and operated in accord with sound engineering practices. (Ord. 599 § 2, 2004)

16.82.390 Market value.

“Market value” shall be determined by estimating the cost to replace the structure in new condition and adjusting that cost figure by the amount of depreciation which has accrued since the structure was constructed. The cost of replacement of the structure shall be based on a square-foot cost factor determined by reference to a building cost estimating guide recognized by the building construction industry. The amount of depreciation shall be determined by taking into account the age and physical deterioration of the structure and functional obsolescence as approved by the floodplain administrator, but shall not include economic or other forms of external obsolescence. Use of replacement costs or accrued depreciation factors different from those contained in recognized building cost estimating guides may be considered only if such factors are included in a report prepared by an independent professional appraiser and supported by a written explanation of the differences.

(Ord. 599 § 2, 2004)

16.82.460 One-hundred-year flood or 100-year flood.

For “one-hundred-year flood” or “100-year flood” see “base flood.” (Ord. 599 § 2, 2004; Ord. 503, 1998; Ord. 174, 1985)

“Start of construction” includes substantial improvement and other proposed new development and means the date the building permit was issued, provided the actual start of construction, repair, reconstruction, rehabilitation, addition, placement, or other improvement was within 180 days from the date of the permit. The actual start means either the first placement of permanent construction of a structure on a site, such as the pouring of slab or footings, the installation of piles, the construction of columns, or any work beyond the stage of excavation; or the placement of a manufactured home on a foundation. Permanent construction does not include land preparation, such as clearing, grading, and filling; nor does it include the installation of streets and/or walkways; nor does it include excavation for a basement, footings, piers, or foundations or the erection of temporary forms; nor does it include the installation on the property of accessory buildings, such as garages or sheds not occupied as dwelling units or not part of the main structure. For a substantial improvement, the actual start of construction means the first alteration of any wall, ceiling, floor, or other structural part of a building, whether or not that alteration affects the external dimensions of the building. (Ord. 599 § 2, 2004; Ord. 503, 1998; Ord. 174, 1985)

16.82.550 Structure.

“Structure” means a walled and roofed building that is principally above ground; this includes a gas or liquid storage tank or a manufactured home. (Ord. 599 § 2, 2004; Ord. 503, 1998; Ord. 174, 1985)

16.82.560 Substantial damage.

“Substantial damage” means damage of any origin sustained by a structure whereby the cost of restoring the structure to its before damaged condition would equal or exceed 50 percent of the market value of the structure before the damage occurred. (Ord. 599 § 2, 2004)

16.82.570 Substantial improvement.

“Substantial improvement” means any reconstruction, rehabilitation, addition, or other proposed new development of a structure, the cost of which equals or exceeds 50 percent of the market value of the structure before the “start of construction” of the improvement. This term includes structures which have incurred “substantial damage,” regardless of the actual repair work performed. The term does not, however, include either:

A. Any project for improvement of a structure to correct existing violations or state or local health, sanitary, or safety code specifications which have been identified by the local code enforcement official and which are the minimum necessary to assure safe living conditions; or

B. Any alteration of a “historic structure”; provided, that the alteration will not preclude the structure’s continued designation as a “historic structure.” (Ord. 599 § 2, 2004; Ord. 503, 1998; Ord. 174, 1985)

16.82.580 Variance.

“Variance” means a grant of relief from the requirements of this division which permits construction in a manner that would otherwise be prohibited by this division. (Ord. 599 § 2, 2004; Ord. 503, 1998; Ord. 174, 1985)

16.82.590 Violation.

“Violation” means the failure of a structure or other development to be fully compliant with this division. A structure or other development without the elevation certificate, other certifications, or other evidence of compliance required in this division, is presumed to be in violation until such time as that documentation is provided. (Ord. 599 § 2, 2004; Ord. 503, 1998; Ord. 174, 1985)

16.82.600 Water surface elevation.

“Water surface elevation” means the height, in relation to the National Geodetic Vertical Datum (NGVD) of 1929 (or other datum, where specified), of floods of various magnitudes and frequencies in the floodplains of coastal or riverine areas. (Ord. 599 § 2, 2004)

16.82.610 Watercourse.

“Watercourse” means a lake, river, creek, stream, wash, arroyo, channel or other topographic feature on or over which waters flow at least periodically. Watercourse includes specifically designated areas in which substantial flood damage may occur. (Ord. 599 § 2, 2004)
