Dundalk homeowners (population 49,530) are part of a busy South Baltimore corridor inside a broader metro that serves 2.5+ million people, and a steady 1.20% annually growth rate means ongoing demand for home upgrades, infill projects, and small-scale construction. That steady growth translates into more driveways, patios, drainage improvements, and landscape refreshes—all projects that depend on reliable bulk materials. In a hardiness zone of 8b with 228/year sunny days and 34.25 inches of annual rainfall, the climate supports year‑round exterior work but also creates predictable needs: materials that balance drainage and compaction, resist erosion on slopes, and support both planting and hardscapes. Choosing the right mix of aggregates, soils, sands, and mulches affects durability, maintenance, and the performance of exterior systems in these local conditions.
