Risk Grade

Poor

Greenville's C grade reflects the structural constraint of being SC's most urbanized county; suburban buildout limits utility-scale parcels; moderate-high compliance score (50) driven by UDO CUP process and council discretion; trajectory worsening as population growth (+2.8%) accelerates suburban land conversion; saturation moderate given limited viable sites
