Code reviser's note: This chapter was amended in its entirety by Ord. 14-00, consisting of Sections 16.16.010 through 16.16.400. Section 16.16.060, Streets – Limited access, was repealed by Ord. 22-00, and the remaining sections of the chapter were renumbered by the city prior to the 2010 recodification.
The city council finds that the protection and preservation of public health, safety and general welfare of the city and its inhabitants and the promotion of orderly development requires that uniform standards for the development of the city and the construction of improvements to the city be established to lessen traffic congestion in the streets, to promote the coordinated development of undeveloped areas, to provide for proper ingress and egress, to ensure that provisions for public utilities and public improvements are provided for and to promote adequate open spaces and parks.

Variances for short subdivisions shall be reviewed administratively and approved by the community development director with an appeal per WRMC 14.01.030. Variances for plats shall be reviewed by the city council during the preliminary plat hearing. The basis for such a variance from the strict application of the requirements of this chapter is undue and unnecessary hardship on the property owner. No variance from the provisions or requirements of this chapter shall be authorized by the council unless the council shall find:
A. 
That exceptional or extraordinary circumstances or conditions exist to the division of the property or to the intended use of the property that do not apply generally to other properties similarly situated.
B. 
That the variance is necessary for the preservation and enjoyment of a substantial property right of the property owner/developer or is necessary for the reasonable and acceptable development of the property. Financial hardship is not a basis for a variance from the provisions of this chapter.
C. 
That the authorization of the variance will not be materially detrimental to the public welfare or injurious to property in the vicinity.
D. 
That the variance from the provisions and requirements of this chapter does not grant a special privilege to the applicant.
