The downhill property matters
Water can leave the court correctly and still create a problem below it.
River-city lots, ridge-top homes, and newer suburban properties can begin with materially different grades, access routes, drainage paths, and surrounding constraints.
A river-city lot, ridge-top home, and newer suburban property do not begin with the same site plan. The evaluation should consider existing slope, cut and fill, retaining walls, soil, geology, erosion, tree removal, downhill drainage, neighboring properties, access, and long-term stability.
When retaining walls enter the project, they affect technical design, drainage, fence foundations, court-edge support, access, landscaping, maintenance, and budget.
Tight river-city properties may bring narrow access, existing walls, urban utilities, close neighbors, existing pavement, and floodplain considerations. Ridge and suburban properties may offer more room while adding wooded slopes, difficult equipment routes, and retaining-wall needs.
The wall is not an accessory. It becomes part of the court's structural environment.
