The Board of Standards and Appeals may permit non-commercial clubs, except swimming pool clubs or clubs with swimming pools located less than 500 feet from any lot line, in R1 or R2 Districts, provided that the following findings are made:

(a)        that such use is so located as not to impair the character of the surrounding area or its future development as a neighborhood of single-family residences;

(b)        that such use is so located as to draw a minimum of vehicular traffic to and through local streets;

(c)        that such use complies with the minimum required open space ratio and maximum floor area ratio for residential use as set forth in Section 23-14 (Open Space and Floor Area Regulations in R1 Through R5 Districts);

(d)        that not more than half the open space provided is occupied by driveways, private streets, open accessory off-street parking spaces or active outdoor recreation facilities; and

(e)        that the amount of open space provided and its distribution on the zoning lot conform to standards appropriate to the character of the neighborhood.

The Board may prescribe appropriate conditions and safeguards to minimize adverse effects on the character of the surrounding area, including requirements for shielding of floodlights, screening or landscaping.
