For a permitted commercial, community facility or manufacturing use on a plan review site or portion of a plan review site existing on November 2, 2023, the City Planning Commission may authorize accessory off-street parking spaces in a plan review site or portion of a plan review site existing on November 2, 2023. In order to grant such authorization, the Commission, upon a review of the site plan, shall find that:

1. vehicular access and egress are located and arranged so as to draw a minimum of vehicular traffic to and through local streets in nearby residential areas;
2. where vehicular access and egress are located on an arterial, such location affords the best means for controlling the flow of traffic generated by such use to and from such arterial, and does not unduly interfere with pedestrian traffic; and
3. the design of the parking facility avoids undue conflict between pedestrian and vehicular movements in a manner that results in a better site plan.

The Commission may prescribe appropriate conditions and safeguards to minimize adverse effects on the character of the surrounding area and may, in appropriate cases, condition its authorization upon compliance with an approved site and landscaping plan. The Commission may also permit modifications to parking lot landscaping and maneuverability requirements only if such modifications preserve natural features.
