Construction and Comments
7
•Residents along project corridor would perceive construction sounds at various
decibel levels due to varying distances, topographic features, and other features
(building) that break the line of sight.
•Staff received one (1) public comment email on August 4, 2023 (Exhibit 19)
regarding construction noise disrupting sleep for a teacher and her high school
age son.
•Staff responded on August 8,
2023 (Exhibit 20).
•The applicant has indicated that
they would develop a monitoring
plan that would address all the
impacts to residents that would
be impacted to minimize any
possibility that the public health
or safety would be diminished
(FOF 9).

Factors For Granting Variance
1) Implementation of a noise monitoring program;
2) Maximum noise levels;
3) Limitation on types of equipment and use of particular equipment;
4) Limitation on back-up beepers for equipment;
5) Required use of noise shields or barriers;
6) Restrictions to specific times and days;
7) Specific requirements for documentation of compliance with the noise variance
conditions;
8) Specific requirements for notification to nearby residents;
9) Required cash security to pay for inspection services to verify compliance;
10) Required access to the project by the City to verify compliance with the noise
variance conditions;
11) Specific program to allow for temporary hotel vouchers to affected residents;
12) Requirements for written verification that all workers understand the noise
variance conditions for the project; and
8
RMC 8-7-8.D.4:
13) Provision allowing the City to immediately revoke the variance approval
if the variance conditions are violated.
