Director Authority. The director may modify the submittal requirements as deemed appropriate to achieve the purpose of this chapter. In addition, because each homeless encampment has unique characteristics, including but not limited to size, duration, uses, number of occupants and composition, the director shall have the authority to impose conditions to the issuance of the permit for homeless encampments to mitigate effects on the community upon finding that said effects are materially detrimental to the public welfare or injurious to the property or improvements in the vicinity. Conditions, if imposed, must relate to findings by the director and must be calculated to minimize nuisance-generating features in matters of noise, waste, air quality, unsightliness, traffic, physical hazards and other similar matters that the homeless encampment may have on the area in which it is located.
