Lot area and width. The lot area shall not be less than 10 acres and the lot width shall not be less than 400 feet, with a minimum of 200 feet of frontage on an arterial highway or collector road as designated by the Township Comprehensive Plan, as amended from time to time.

When a portion of the perimeter of the tract abuts a nonresidential use or district, all structures shall be a minimum of 50 feet from that portion of the perimeter.

The number of beds provided in intermediate care and skilled care unit shall not constitute more than 25% of the total number of beds in the residential care facility.
(2)
The total allowable number of beds for the residential care facility shall be calculated on the basis of lot area, as defined in § 208-6, and the type of underlying zoning district.

(c)
Nonresidential districts: maximum density of 30 beds per acre.
(3)
Any proposed permanent change to the ratio of the types of units provided in a residential care facility shall constitute a modification of the conditional use requiring a new conditional use approval upon application to the Board of Supervisors.
