Two routes exist to work outside the standard hours: the City Manager may waive any or all of the subsection's provisions in cases of urgent necessity or in the interest of public health and safety, and the hours may also be modified through a Conditional Use Permit or other development entitlement processed under the City's normal procedures. 050.
