Development Standards. <br />1. There shall be one hundred twenty-five (125) square feet of usable open space per dwelling <br />unit. <br />2. Usable open space may consist of outdoor area on the ground, in front, street side, interior side, <br />or rear setback areas or on any balcony, deck, porch or rooftop which is designed and accessible <br />for outdoor living, recreation, pedestrian access or landscaping complying with the following <br />provisions: <br />1a. Required parking areas and their driveways shall not be included in computing usable <br />open space; <br />2b. Area included in computing common usable open space shall be accessible to all units in <br />common and no such required space shall be less than three hundred (300) square feet <br />in area and shall have no dimension less than fifteen (15) feet; rooftop gardens and <br />rooftop landscaping, including rooftops above parking structures, may be used to satisfy <br />this requirement; <br />3c. Private usable open space may be substituted for common usable open space, provided <br />such element of open space either has an area of at least one hundred fifty (150) square <br />feet, with no dimension less than ten (10) feet, if located at ground level, or an area of at <br />least fifty (50) square feet, with no dimension less than six (6) feet, if located above <br />ground level; <br />4d.

Where possible, pervious areas set aside as usable open space may also serve as areas for <br />infiltration of stormwater runoff, subject to review and approval by the Engineering and <br />Construction Division.
