Limited Nonresidential Use Within Active Adult Community. Limited nonresidential use may be included as an accessory use within an active adult community only, not to exceed 5% of the total proposed interior building area, in order to allow for professional office, retail sales, and retail service uses. All nonresidential uses must be limited to the ground level. Each individual nonresidential use shall be limited to be no less in size than 1,000 and no greater in size than 3,000 square feet. No fabrication, manufacturing, or processing shall be allowed on site. These nonresidential uses shall enhance the life style of active adult residents within the complex. All proposed such uses and future changes in any of the original uses must be reviewed by Council to assure compliance with this section. It is the specific intent of this subsection to permit Borough Council the discretion, based on substantial supporting evidence and proof, that there will be no detriment to the public interest. The intent is also to limit the "trips" from the complex during peak traffic times without detracting from the "Town Center." All nonresidential uses must satisfy the parking mandates as delineated in § 27-2001 of this chapter.
