6-story wood V-A over concrete podium: 3,500 sf ground-floor retail on Monroe Ave, 60-space podium parking, 48 units stacked above. TN-CC permits this massing on a 0.42-acre lot (effective FAR 4.0 within OD-DH-1 overlay). Form-based zoning allows 0.5/unit parking ratio; we hit that at 60 spaces total factoring retail (1.5 per 1,000 sf) plus 50 residential.
