Greater St. Louis
Different Property Patterns, Different Site Questions
The final build will distinguish urban, inner-ring, later-subdivision and outer-metro/rural contexts rather than describing one universal St. Louis yard.
Historic St. Louis City
Narrow lots, alleys, dense neighboring structures, older drainage infrastructure, mature hardscape and repeated landscape changes.
Inner-Ring Suburbs
Mature trees, older patios and drives, decades of additions and changing grades.
Later Subdivisions
Mass grading, storm-sewer networks, detention/retention infrastructure and larger impervious areas.
Outer Metro & Rural
Ditches, larger slopes, ponds, acreage, septic/well relationships and agricultural ground.
Historical Evolution
How Residential Sites Changed Over Time
These are overlapping regional trends, not a universal sequence followed by every property.
Natural Landscape
Topography, watercourses, soils and vegetation predate development.
Agricultural Parcel
Fields, lanes, ditches and working landscapes shaped rural land use.
Urban Lot & Alley
Compact parcels and service alleys changed drainage and access patterns.
Formal Residential Yard
Ornamental planting, walks and service yards became part of domestic design.
Automobile Driveway Era
Driveways and garages increased residential hardscape.
Postwar Lawn Suburb
Larger lawns and mass-graded subdivisions reshaped site patterns.
Outdoor Living Expansion
Patios, terraces and recreation areas increased impervious surfaces.
Engineered Drainage
Storm sewers, inlets and detention systems became common subdivision infrastructure.
Stormwater Management Era
Runoff quantity and quality increasingly shaped public and private site planning.
Rain Gardens & Permeable Surfaces
Contemporary landscapes increasingly combine planting with stormwater performance.
Assessment Workflow
Observe the Site During Real Weather
Dry-day inspections often miss the most useful drainage evidence.
1. Observe During Weather
Watch the property during or immediately after meaningful rainfall.
2. Identify the Source
Roof, neighbor, irrigation, slope, groundwater or another source?
3. Map the Flow
Where does water travel across the surface or through drains?
4. Identify Storage / Infiltration
Where can water soak in or temporarily collect?
5. Find the Outlet
Where does collected water ultimately discharge?
6. Review Overflow
What happens when the primary system is overwhelmed?
7. Document Buried Systems
Drain lines, inlets, dry wells, utilities and unknown pipes.
8. Preserve Records
Photos, surveys, contractor plans, permits and maintenance history.
Research Architecture
