B.
- c.
Where the literal interpretation and enforcement of these standards would result in practical difficulties, environ- mental degradation or results inconsistent with the general purpose of these standards, the .Planning Commission shall have the authority as .an administrative act to grant a vari- ance to these standards subject to the provisions stated below. In all. cases, the variance shall be in harmony with, the general purpose and intent of the standards and with the safety and the welfare of the public.
The areas wherein the design standards for street widths and improvements may be deleted or modified, may include, but hot be limited to, narrowing the right-of-way width, narrowing
of the roadway width, deletion of sidewalks, deletion of curbs, separation of opposing trafgic lanes around sensitive environmental features, reduction of lighting standards in sensitive environmental habitats and other design modifica-,
tions consistent'with the conditions and intent'of this sec- tion.
Before any variance may be granted, it shall be shown:
(1) That there are extraordinary.or unusual circumstances or conditions applicable to the situation of surrounding property necessitating a variance of the standards.
That the granting of such variance will not casue sub- stantial drainage problems. (2)
(3) That the granting of such variance will not conflict with existing or future traffic and parking demands or pedestrian or bicycle use.
(4) That the granting of such variance will not be detri- mental to-the public welfare or injurious to the prop-
erty or improvements in the vicinity in which,the vari- ance is granted.
That the granting of such variance will not adversely affect the comprehensive general plan. ' (5) -
