Key Definitions:

“Development”

“Director”

“Disturbed Area”

“Land Disturbing Activity”

“Maximum Extent Practicable”

“Redevelopment”

Variances (§20-3-64) 8

For deviations from the Rules, applicants must submit a petition for variance to the director and may be authorized if all of the following are true:

The variance is necessary to prevent a hardship caused by unique Site conditions on the property that are not ordinarily found in other areas within the City;

The unique conditions on the property are not the result of petitioner’s own actions or the actions of h/her agents, contractors, consultants, or tenants;

Granting a variance will not adversely affect the rights of abutting property owners;

The variance requested will not result in an unreasonable threat of Pollutant discharges to the MS4 or State Waters;

The variance requested is the minimum accommodation needed to overcome the hardship caused by naturally occurring conditions on the property; and

Pollutant discharges to the MS4 and State Waters will not exceed levels that would occur if the petitioner complied with a strict application of these rules.
