Georgetown defines impervious cover as any hard-surfaced, man-made area that doesn’t readily absorb water: roofs, driveways, pavement, sidewalks, graveled areas, and paved recreation areas. The city’s limits exist to reduce flooding and control stormwater runoff. That makes the first patio question not “how large can it be?” but “how much cover does the lot already carry, and what does the survey allow?”
Â
Georgetown’s patio and flatwork requirements include an official site survey showing property lines and the proposed location with dimensions, construction drawings, and impervious cover calculations on the survey site plan or worksheet.
Â
A badly placed patio creates drainage problems the homeowner won’t notice until after construction. Capital Outdoor Spaces plans patio layouts around remaining site compliance, shade, drainage slope, furniture circulation, and movement from the home.
Â
When impervious cover gets tight: Georgetown allows permeable pavers to potentially meet city and TCEQ requirements when a project exceeds platted impervious cover limits. That’s not a material substitution. That path can require engineered water-quality design, runoff coefficient confirmation, detention calculations for multiple storm events, WPAP updates, TCEQ recordation, maintenance agreements, water-quality easements, infiltration testing, and a TCEQ completion letter. Capital Outdoor Spaces treats that as a documented design route, not a workaround.
