Structures and site guide
Deck, patio, pool, and landscape coordination
Treat outdoor features as a connected site plan with drainage, access, fall, water, utility, and barrier risks.
Direct answer
Map grades, drainage, utilities, property constraints, doors, routes, supervision, and maintenance before shaping outdoor features. Pools require layers of safety protection; decks and elevated surfaces require verified structure, attachment, guards, and footings.
Planning workflow
- Obtain reliable site dimensions and map utilities, drainage, easements, slopes, and vegetation.
- Place activity zones, accessible routes, equipment, gates, barriers, doors, stairs, and service access.
- Keep water flow away from structures and expose changes in level.
- Request landscape, structural, electrical, plumbing, pool-safety, and local permit review as applicable.
Formula or decision logic
Calculate surface quantities from measured polygons, but treat safety as a constraint network: every path from dwelling or public approach to pool water must encounter the required verified protective layers. A barrier line on a plan does not prove height, openings, gate operation, alarms, visibility, supervision, or local compliance.
Worked planning example
A 14 by 20 ft deck is 280 sq ft before stairs and waste. If it sits above sloping grade, the support height and guard condition vary along the edge. A nearby pool adds gate, barrier, electrical, drainage, and supervision questions; the calculator reports surface area while the plan retains explicit unresolved safety flags.
Limitations and review boundary
- CPSC pool guidance is not a substitute for local law or supervision.
- Deck attachment, loads, footings, guards, and stairs require verified design.
- Site grading and drainage need field information.
