. application shall stain information which d ~nstrates
~ ~ that bringing the rce of sound or activit~~r ~•7hich
` the variance is so t into compliance with tc.<s Ordinance,

community, or other persons.
(c) In determining whether to grant or deny the
application, the Planning Commission shall balance the hard-
ship to the applicant, the community, and other persons by

required to submit .any information to the Planning Commission
that they may reasonably require. In granting or denying
an application, the Planning Department shall. place on public
file, a copy of the decision and the reasons for denying or
granting the variance for time to comply.

(e) Application for extension of time limits speci-
fied in variances for time to comply, or for modification of
other substantial conditions, shall be treated as. applications

tension or modification clearly outweighs any. adverse impacts .

defining the procedures to be followed in applying for a
> variance for time to comply and the criteria to be considered
in deciding whether to grant a variance.
(g) FINDINGS
No variance shall be granted unless the Planning
Commission makes all of the following findings:
(1) That the applicant is or will be in violation
of this Ordinance.
(2) That, due to conditions beyond the reasonable
control of the applicant, requiring compliance would result
in either;
(a) an arbitrary or unreasonable taking of
property; or

a corresponding benefit in reducing noise levels.
