Retention Basins FAQs
What is a retention basin, and does it need maintenance?
A retention basin holds a set amount of stormwater runoff from higher-elevation areas and helps protect the water quality of connected streams, rivers, lakes, and bays. Yes — retention basins need regular maintenance to keep a property’s stormwater management system working properly.
What does a paving contractor do?
A paving contractor prepares, grades, and surfaces driveways, parking lots, and roadways with asphalt or concrete, and maintains those surfaces over time. Shane’s Grading and Paving handles the full range — grading, paving, sealcoating, asphalt maintenance, building pad preparation, exterior demolition, and retention basins — for both residential and commercial properties in the Phoenix, AZ area.
What’s the difference between paving and grading?
Grading shapes and levels the ground so it drains correctly and provides a stable base. Paving is the surfacing work that goes on top of that graded base — asphalt or concrete. Most paving projects need both, in that order.
