Full Breakdown
Davenport applies two separate limits in Table 17.04-1 (Sec. 17.04.030): maximum building coverage and maximum impervious surface. R-1 caps building coverage at 25% and impervious surface at 40%. R-2 allows 35% building coverage and 50% impervious; R-3 allows 35% and 60%. The R-4 and R-4C districts reach 35% and 40% building coverage respectively, with impervious surface up to 60%. Impervious area includes buildings, driveways, patios, and walkways. Any project creating 5,000 square feet or more of impervious surface also triggers stormwater-quality requirements under Chapter 13.34.
Violations & Fines
Exceeding building coverage or impervious-surface limits requires correction, which may mean removing pavement or structures. Fines apply as municipal infractions, and over-paved lots may face added stormwater-management requirements under Chapter 13.34.
