Pearl Arts District
Status: In Progress — Concept plan stage; formal site review not yet submitted Lead Body: Planning Board → City Council (rezoning + 20-year vesting ordinance required) Related Bodies: City Council, Design Advisory Board, Boulder Urban Renewal Authority First Discussed: February 2026
The Pearl Arts District is a proposed major mixed-use redevelopment at 3550 and 3580 Frontier Avenue — the 10.8-acre site at the southeast corner of Pearl Parkway and Foothills Parkway, currently occupied by Sanitas Brewing, Black Lab Sports, Boulder Pickleball, and Las Fortiva. The project, developed by Conscience Bay (Daniel Eisenman), would create a 2,500-person performing and events venue, 8,500 sq ft of rehearsal space for local arts organizations, a 150-room hotel, approximately 500 apartments, 30,000 sq ft of food/beverage and retail, and structured parking.
The site sits within the TVAP Phase 2 boundary with a MUTOD land use designation, but is zoned IS1/IS2, requiring a rezoning — likely to a modified MU4 or a new zone requiring a City Council ordinance. A 20-year vesting period was requested (standard is 3 years; anything beyond requires Council ordinance). Critical constraint: the site is in the 100- and 500-year Boulder Slough floodplain. A $5M FEMA-approved regional flood mitigation project (Phase 0, trestle bridge under BNSF rail) must be completed before any construction begins.
Planning Board held a concept plan review in February 2026 and provided extensive design guidance, leaning toward a modified MU4 approach rather than creating a new zone district.
Project Components
| Element | Scale |
|---|---|
| Performing arts / events venue | 2,500-person capacity; ~180 events/year, 60 community-use slots |
| Rehearsal space | 8,500 sq ft for local arts organizations |
| Hotel | 150 rooms |
| Residential | ~500 apartments |
| Retail / F&B | 30,000 sq ft |
| Building heights | 2–5 stories (height modification to 55-ft charter limit requested) |
Site Constraints and Process
- Floodplain: 100- and 500-year Boulder Slough floodplain; Phase 0 flood mitigation must precede construction
- Phase 0: $5M FEMA-approved regional project; trestle bridge under BNSF rail; not yet constructed
- Zoning: IS1/IS2 now; MUTOD designation requires MU4-equivalent zone (2.0 FAR standard) or new zone via Council ordinance
- Vesting: 20-year vesting requested; standard 3 years; anything beyond requires City Council ordinance
- Buildout: Projected 10–15 years, 4 phases (infrastructure first, then venue/hotel/apartments, then remaining residential)

Key Decisions
- 2026-02-03 — Board concept guidance: majority lean toward modifying MU4 rather than creating a new zone; rezoning and 20-year vesting ordinance will require City Council action
- Board consensus that performing arts venue qualifies as "indoor commercial recreation" under MU4 via use review
- Phase 0 flood mitigation is prerequisite; its completion is not solely within applicant or city control
Open Questions
- Will MU4 be modified, or will a new zone district be created by City Council ordinance?
- How will the 20-year vesting request be handled (standard is 3 years)?
- Status of Phase 0 flood mitigation funding and timeline
- Connection to Urban Renewal / TIF: site is in TVAP Phase 2 — does it fall within any BURA candidate area?
- How does the large-scale arts venue relate to Sundance Film Festival venue needs and the Special Festival Events designation?
- MU4 FAR limit is 2.0; applicant requested 2.2 — what flexibility exists?
