A. 
To preserve as many as possible of the desirable characteristics of one-family residential districts while permitting certain limited commercial and office uses where deemed compatible with residential uses such as along Grove Street.

To protect the historic character and setting of the surrounding neighborhood by providing special setback, building size, and design review requirements to ensure compatibility of new development with older development in the area.
