Waiver from planning code requirement due to hardship of the applicant.

A device which grants a property owner relief from certain provisions of the Critical Area ordinances when, because of the particular physical surroundings, shape, or topographical condition of the property, compliance would result in a particular hardship upon the owner, as distinguished from a mere inconvenience or a desire to benefit economically. Authority to decide variances is vested in the local jurisdiction's Board of Appeals or, in certain jurisdictions, a special hearing examiner. All variances granted by Boards of Appeal or hearing examiners within the Critical Area are reviewed by Critical Area Commission staff for consistency with State regulations.

A limited waiver from the requirements of the zoning ordinance, or building code, that may be granted because of special circumstances regarding the subject property. A land use variance usually requires a public hearing before the Planning Commission, Zoning Board,or Zoning Administrator.

A variance is an exception granted by the City Council from the zoning requirements of a particular zoning district. Variances can be granted when performance standards, such as setbacks, cannot be met due to unusual physical site characteristics, called a 'hardship'. A hardship is related to the physical characteristics of the land, such as slopes or mature trees. The property owner most prove there is a hardship and the variance requested is necessary to alleviate a physical hardship caused by unusual circumstances. Variances cannot be used to either establish or enlarge a use which is not otherwise permitted in the zoning district. Variance applicants usually become aware of the need for a variance because they have applied for a building permit and have been told by the Inspection Department that the structure does not comply with a zoning performance standard.

See Relaxation | | | | | | | | | | | | | | | P-Q | | | | | V-W | X-Y-Z"X - Z"

A variance is permission to engage in an act contrary to a usual rule. A property owner might request a variance regarding the use of the land, setbacks, height limitations, or the percent of the property to be covered by structure. A hearing is held by the planning department to determine if a variance will be granted. Owners of neighboring properties are invited to express their views. Each planning department has their own criteria. As an example, the applicant might be expected to explain how one or more of these factors apply: That the applicant would be deprived of the reasonable use of the land or building, if the zoning code were strictly applied. That there are unique circumstances, different from the general conditions of the neighborhood. That the variance sought would not alter the essential character of the locality. That it would not be contrary to the intent and purpose of the zoning code.

The water system must prove that: (1) it cannot meet a MCL, even while using the best available treatment method, because of the characteristics of the raw water, and (2) the variance will not create an unreasonable risk to public health. The State or EPA must review, and allow public comment on, a variance every three years. States can also grant variances to water systems that serve small populations and which prove that they are unable to afford the required treatment, an alternative water source, or otherwise comply with the standard.

If you have a sufficient advantage at the game you're playing, you expect to make money over the long haul. This is true whether the game is poker, blackjack, or craps, and whether your advantage is due to skill, cheating, or psychic powers. However, over a small period of time, you may do better or worse than what your average should be. For example, you may expect to make one big bet per hour at the poker table, but in a given hour it may not be uncommon for you to win or lose twenty big bets. Variance is the statistical measure of dispersion, or just how widely your results will be distributed. When variance is high enough, a small advantage may be of no use during your lifetime. When variance is low enough, a small sample will be much more likely to reflect your real advantage (or disadvantage). In other words, variance describes just how long the long haul is. In poker terms, high variance means that a small number of hands will not be very representative of your long-term expectation.

Deviation from a standard or norm

A method by which a government body formally deviates from the terms of its sign or zoning ordinance. Typically, obtaining a variance for a sign requires the applicant to show that it would not be contrary to the public interest or that a literal enforcement of the regulations would result in unnecessary and undue hardship (due to conditions unique to the property).

(Statistics) A measure of the spread or dispersion of a variable about its Mean or Arithmetic Mean value. The variance is calculated by taking the sum of the squares of the deviations, that is, the sum of the difference between the observed value and the series mean value, and dividing by the sample size (number of observations). The variance for a large data set (the population variance) is calculated as: s2 [sigma] = ( xi — x [sigma] = ( xi — x where: xi is an individual observation; is the mean of all observations; and is the number of observations. xi is an individual observation; is the mean of all observations; and is the number of observations. For smaller data sets (typically less than 50) the sample variance (s2) is calculated by replacing with —1 in this equation. The positive square root of the variance is called the Standard Deviation. Both the variance and the standard deviation are non-negative, by definition.

Mathematically, the sample variance is the sum of squares of the differences between the individual values of a set and the arithmetic average of the set, divided by one less than the number of values: For a finite population, the variance s2 is the sum of squares of deviations from the arithmetic mean, divided by the number of values in the population: where µ is the true arithmetic mean of the population.

Variance is a measure of the variability or dispersion in the distribution of measurements or scores. For example, consider hemoglobin measurements on two separate groups of children. The measurements in group A may be widely dispersed while the measurements in group B may be clustered around the central point. In this case, the group A distribution would have greater variability or variance than group B. In statistical terms, the variance is the mean of the squared deviations about the mean. Formulas for the calculation of variance can be found in any basic statistics text book.

The degree to which a set of quantities vary: A measure of the spread of scores in a distribution of scores, that is, a measure of dispersion. The larger the variance, the further the individual cases are from the mean. The smaller the variance, the closer the individual score are to the mean. Specifically, the population variance is the mean of the sum of the squared deviations from the mean score. The Sample variance is computed by dividing the sum of squared deviations by the number in the sample minus 1. The Standard Deviation is the square root of the variance.

An allowable deviation from the land use prescribed by the existing zoning ordinances.

A measure of the dispersion of a set of data points around their mean value. It is a mathematical expectation of the average squared deviations from the mean.

Measures the volatility of a data set/data points from the mean. It is calculated by adding the squares of the standard deviations from the mean and dividing by the number of data points, i.e. taking the average of the standard deviations.

The second moment around the mean; the expected value of the square of the deviations of a random variable from its mean value.

1) The difference between the expected (budgeted or planned) value and the actual. 2) In statistics, a measurement of dispersion of data. See: estimate of error.

The most commonly used statistical measure of dispersion. The first step is to square the deviations of a data item from its average value. Then the average of the squared deviations is calculated to obtain an overall measure of variability.

In probability theory and statistics, the variance of a random variable (or somewhat more precisely, of a probability distribution) is a measure of its statistical dispersion, indicating how its possible values are spread around the expected value. Where the expected value shows the location of the distribution, the variance indicates the scale of the values. A more understandable measure is the square root of the variance, called the standard deviation.

In the Labor Distribution System (LDS), a difference between the Payroll and the LDS records.

The difference between a planned, budgeted or standard cost and the actual cost incurred. The same comparisons may be made for revenues.

The difference between planned, budgeted or standard cost and actual cost (or revenue). Variance analysis is an analysis of the factors which have caused the difference between the pre-determined standards and the actual results.

Magnetic north and true north do not coincide at the same geographic point. They differ by a number of degrees. The discrepancy between magnetic and true north also differs with location. Variance is the amount, at some geographic point, by which the direction to magnetic north varied from the direction to true north.

in accounting, is the difference between a projected number and the actual number, e.g. 1. a budget variance is spending either more or less from the amount that was budgeted; and 2. a cost variance is the difference between actual cost and standard cost in the categories of direct material, direct labor, and direct overhead.

In accounting, the difference between the actual cost and the standard cost for direct material, labour and overhead.

an event that departs from expectations

The difference between actual and targeted numbers for revenues, expenditures, or productivity. Variances are usually described as either favorable or unfavorable. See also standard costs.

A calculation of the difference between plan and actual results, used by analysts to manage and track the impact of planning and budgeting.

This is a calculation that dates back to the early 1900s, when it was used by factories to track the difference between their budgeted costs and their actual costs. Variance is now the core of a project management system called earned value management, which tracks the project by considering effort â€œearnedâ€ against a budget only after it has actually been performed.

The difference between the budget and the actual amount of income or expenditure on any one Accounts Code or for an entire Budget.

Difference between standard cost and actual cost. Also, the difference between an actual revenue or expense item and the budget for that item (budget variance).

a discrepancy between the actual and planned performance on a project, either in terms of schedule or cost.

The difference between what is expected and what actually occurs. Usually encountered when talking about the differences in playing Multihand games where the variance is higher than in single hand mode thus requiring the player to wager more to achieve the expected return.

The difference between what was expected and what is actual. This can be applied to the budget, schedule, or specifications.

The difference between what was planned and what actually happened. Variances are part of budget monitoring and causes of variances should be found to permit total understanding of the current position.

The difference between a project's baseline status and current status.

The difference between planned and actual costs (and revenue).

A term used with standard costs to report a difference between actual costs and standard costs. To learn more, see Explanation of Standard Costs & Variances. To Top

The difference between budget and actual expenditure or between planned and actual action expressed as a plus or a minus figure in management reports.

In budgeting (or management accounting in general), a variance is a difference between budgeted, planned or standard amount and the actual amount incurred/sold. Variances can be computed for both costs and revenues.

Difference that produces dispute or controversy; disagreement; dissension; discord; dispute; quarrel.

A disagreement or difference between two parts of the same legal proceeding, which, to be effectual, ought to agree, -- as between the writ and the declaration, or between the allegation and the proof.

Any mechanism or provision under Sections 301 or 316 of the CWA or under 40 CFR Part 125, or in the applicable "effluent limitations guidelines" which allows modification to or waiver of the generally applicable effluent limitations requirements or time deadlines of the CWA. This includes provisions which allow the establishment of alternative limitations based on fundamentally different factors.

A mechanism or provision that allows modification to or waiver of requirements or standards.

An exemption given by the State to a water system if an MCL cannot be met; given that certain conditions are met by the water system.

A State with primary enforcement responsibility under the Safe Drinking Water Act may relieve a public water system from a requirement respecting an MCL by granting a variance if certain conditions exist. These are:

A VaR measure that calculates the volatility of each risk factor from historical data an estimates its effect on the portfolio to give an overall composite VaR that includes all risk factors.

The difference between two area calculations of a subject suite, floor or building area made by two individuals. The area calculation of a building owner is deemed accurate if the variance between their area calculation and that of another party is less than 2% under the BOMA, GWCAR and NAHB Standards.

When a group sends in premium with number of lives and either the premium or the commission amounts are not equal to what the system calculates for that number of lives. We then send out a variance letter with a correct worksheet and explain the difference. Enrollment variance for underwriting purposes is when there is a change greater than 10% in the enrollment of the group, the underwriter may choose to trigger a provision of the policy and change the rates and/or factors the group contract is based on.
