[Res. No. 135-90, § 1, 11-27-1990]
It is hereby declared as a matter of public policy that the protection, enhancement, and perpetuation of landmarks and monuments, and the establishment of historic districts and/or historic interest districts is necessary to promote the cultural, educational, economic, and general welfare of the public. Inasmuch as the identity of a people is founded on its past, and inasmuch as Olean has many significant historic, architectural, and cultural resources which constitute its heritage, this chapter is intended to:
(1) 
Protect and enhance landmarks and monuments and historic districts, when created, which have a special character or special historical or aesthetic interest or value which represent distinctive elements of Olean’s historic, architectural, and cultural heritage;
(2) 
Foster civic pride in the architecture and historic accomplishments of the past;
(3) 
Protect, promote, and enhance Olean’s aesthetic qualities for the benefit of residents and visitors; and
(4) 
Ensure the harmonious, orderly, and efficient growth and development of the city.
[Res. No. 135-90, § 4, 11-27-1990]
(a) 
When consulting with owners of property in landmark or historic districts, the historic preservation commission shall determine whether the proposed alteration, demolition, or construction is compatible with its historic character, as well as with the surrounding properties. If the commission determines that it is not, the commission’s efforts shall be directed toward convincing the owner to eliminate from his plans any work which would alter the special character, historic or aesthetic interest, or value which constituted the basis for the landmark, monument, or historic district designation.
(b) 
When deciding whether or not any alteration, demolition, or new construction is compatible, the commission shall consider the following criteria:
(1) 
General design, character, and appropriateness to the property of the proposed alteration, demolition, or new construction;
(2) 
Scale of the proposed alteration or new construction in relation to the property itself, surrounding properties, and the neighborhood;
(3) 
Texture, materials and color and the relation to the similar features of other properties in the neighborhood;
(4) 
Visual compatibility with surrounding properties, including proportion of properties, front facade, proportion and arrangement of windows and other openings within the facade, roof shape, and rhythm of spacing of properties on street;
(5) 
Importance of historic, architectural, or other features to the significance of the property; and
(6) 
Each and every other factor which the commission deems appropriate to its decision.
