Commission supports pedestrian-focused Sienna gateway concept, directs staff to draft parking language

Staff presented proposed amendments to a Planned Development covering 57 acres of the CNIMD annexation area, recommending inclusion of commercial retail uses (LC1–LC3 lists), architectural design standards, pedestrian connectivity, requirements for outdoor gathering spaces on developments of 10,000 sq ft or greater, and gateway corner enhancements to create a placemaking entry to the city. Staff said the proposed regulations would apply to commercial tracts (A1, A1B, A3) and noted one written protest letter requesting more green space.

"Additionally, requiring pedestrian connectivity within the commercial retail areas," staff said during the presentation, describing a push to prioritize walkability over auto orientation and to require outdoor seating or gathering space for larger developments. Commissioners broadly praised the placemaking vision and pressed staff on how to lock parking location and layout into ordinance language. Several commissioners suggested a decentralized parking model — locating parking to the outskirts of the activity area so parking does not impede pedestrian flow — and asked staff to return with specific draft language and example exhibits to show how the concept would work for the limited land on the two commercial corners. Rather than vote, the commission provided direction and asked staff to prepare revisions and illustrative exhibits for the next P&Z meeting.
