5 and undergoing expansion or redevelopment, see subsection
3.4.11E.4.
3.
Credit for preservation of existing trees and trees planted
to fulfill mitigation requirements. All development must preserve
or replace at least sixty percent (60%) of the caliper inches of trees
present on site prior to development according to an approved Tree
Survey. The caliper inches of tree species listed in
Table 6.1-1 Exempted Trees when measuring
twelve (12) caliper inches and or larger and all other trees four
(4) inches caliper or larger shall be counted towards the required
sixty percent (60%).
(i)

1. General provisions.
(i)
Unless otherwise proscribed within this Article, the City Council may approve a waiver to one or more provisions of Articles
5 if it makes an affirmative finding with regard to the following:
(1)
That undue hardships will result from strict compliance with
one or more provisions of this Article;
(2)
That the purposes of these regulations may be served to a greater
extent by an alternative proposal;
(3)
The waiver does not have the effect of nullifying the intent
and the purpose of the applicable regulations;
(4)
Granting the waiver will not be detrimental to the public safety,
health or welfare, and will not be injurious to other property or
to the owners of other property, and the waiver will not prevent the
orderly development or use of other property in the vicinity;
(5)
The conditions upon which the request for a waiver is based
are unique to the property for which the waiver is sought, and are
not applicable generally to other property;
(6)
Because of the particular physical surroundings, shape or topographical
conditions of the specific property involved, a particular hardship
to the property owner would result, as distinguished from a mere inconvenience,
if the strict letter of these regulations is carried out; and
(7)
An alternate design will generally achieve the same result or
intent as the standards and regulations prescribed.
(ii)
Such findings of the City Council, together with the specific
facts upon which such findings are based, shall be incorporated into
the official minutes of the City Council meeting at which a waiver
is considered.
(iii) The City Council may grant a waiver from a provision of Article
5 when the relief granted is in harmony with the general purpose and intent of the Article and when the safety and welfare of the public will be secured and substantial justice done.
(iv)
Financial hardship to the property owner or developer does not
constitute undue hardship as defined in subsection
(i) above.
2. Conditions. In approving a waiver, the City Council may require such conditions which, in its judgment, secure substantially the purpose described the applicable Section of Article
5.
3. Procedures.
(i)
The applicant must submit a petition for a waiver in writing
by the applicant with the Site Plan or development application. If
the applicant does not submit a petition in writing, the associated
application will not be considered complete (see section
1.4.2.E Application Considered Complete).
(ii)
The petition shall state fully the grounds for the application
and the facts relied upon by the petitioner.
(iii) Where a hardship is identified pursuant to this section which requires issuance of a waiver from a provision in this Article, the Planning and Zoning Commission may, in its consideration of an associated Site Plan or other development application it is required to consider, recommend to the City Council a waiver from the provision in this Article
5.
(iv)
The City Council may grant final approval to a waiver from a
provision of this Article provided that no new information or reasonable
alternative plan exists which, at the determination of the City Council,
voids the need for a waiver.
(v)
The City Council's decision is final.
