18.22.055 Findings for denial of a tentative subdivision map.¶
The planning commission shall not
recommend approval and the city council shall not approve a tentative subdivision map if any of the following findings are made:
(A) That the proposed tentative subdivision map is not consistent with the city's general plan or its elements or other applicable plans;
(B) That the design or improvement of the proposed subdivision is not consistent with the city's general plan or its elements or any other applicable plans;
(C) That the site is not physically suitable for the type of development proposed;
(D) That the site is not physically suitable for the proposed density of development proposed;
(E) That the design of the subdivision or the proposed improvements are likely to cause substantial environmental damage or substantially and avoidably injure fish or wildlife or their habitat;
(F) That the design of the subdivision or the type of improvements is likely to cause serious public health problems;
(G) That the design of the subdivision or the type of improvements will conflict with easements, acquired by the public at large, for access through or use of, property within the proposed subdivision. In this connection, the city council may approve a tentative subdivision map if it finds that alternate easements, for access or for use, will be provided, and that these will be substantially equivalent to one previously acquired by the public.

(C) The city council may extend the expiration date of any tentative subdivision map for not more than twelve months at any one time.
