Full Breakdown
Putnam County Code Sec. 45-502 ties maximum floor area ratio and impervious surface coverage to Table 7.02B, and any variance from those limits cannot exceed the table's ceiling because the numbers derive from the comprehensive plan, not just the zoning code. Under Table 7.02B, land in the Urban Service future land use category is capped at 70% impervious surface for residential development (1:1 floor area ratio and 85% impervious surface for non-residential); Urban Reserve allows 70% residential impervious coverage with a 0.5:1 residential floor area ratio; Rural Center and Rural Residential both cap residential coverage at 50%, with floor area ratios of 0.5:1 and 0.4:1 respectively.
Commercial, Industrial and Public Facilities categories carry no residential allowance (marked NA) but permit 85%, 85% and 70% non-residential impervious coverage respectively. Conservation-designated land is capped at just 10% impervious surface for both residential and non-residential uses, and Mining land carries no listed cap at all. Sec. 45-502(b)(2) notes these percentages are upper limits that may be further cut by drainage requirements, the zoning district's own rules, soil conditions, aquifer recharge potential or other environmental factors under article VI. Sec. 45-501's district-by-district table cross-references Table 7.02B for every zoning district's maximum impervious surface figure rather than setting a separate number there.
Violations & Fines
Exceeding the impervious surface or floor area ratio ceiling in Table 7.02B, including through a variance that tries to go beyond it, is not permitted; site plans that exceed the cap are rejected by planning and development services, and built violations go to code enforcement before the Special Magistrate. A Sec. 1-6 general penalty of a fine up to $500.00, up to 60 days in jail, or both applies to Code violations.
