If the number of parking spaces required by this Chapter for a non-residential use is substantially larger than the number anticipated by the applicant and the applicant provides sufficient evidence that supports the reduced parking needs, a development plan may be approved with an allowance for the construction of a lesser number of parking spaces provided that:
(a) The total number of spaces initially constructed and/or an area set aside on the site of the principal use shall not be less than seventy percent (70%) of the spaces required by this Chapter.
(b) Suitable additional area(s) are reserved for the construction of the balance of the total number of spaces otherwise required by this Chapter. Such suitable areas shall be illustrated on the development plan in locations and with landscaping in full compliance with this Development Code.
(c) The Planning Commission, upon reevaluation of the project's parking needs, may at any time direct that some or all of the parking spaces identified in sub-section (b) be constructed.
(d) When additional parking is determined necessary, it shall be provided according to the approved development plan.
