Project staff described changes to building design standards. The draft reduces three tiers of materials and design standards to two and consolidates materials between tiers. As staff summarized: tier 1 materials include brick, natural and manufactured stone and architectural concrete masonry units; tier 2 includes synthetic stucco (EIFS), precast concrete and architectural metal panels.

Committee members debated whether corrugated metal siding should be allowed. One participant suggested a compromise: "Call it architectural corrugated metal panel and then prohibit industrial," arguing that a high‑quality, defined product could be distinguished from lower‑grade, rust‑prone corrugated metal.

Staff said the intent is to avoid overly prescriptive requirements that would make development cost‑prohibitive while still prohibiting clearly lower‑quality materials such as unfinished concrete block and basic vinyl siding. No formal action was taken; staff will add a clear definition for "architectural corrugated metal panel" and refine the prohibited materials list before the public open house and planning commission review.
