Map the water path
Record high and low points, downspouts, hard surfaces, neighboring runoff, seasonal changes and the proposed outlet. Verify that discharge is lawful and will not shift harm elsewhere.
Match the intervention
Regrading can address surface flow. Swales collect broad runoff; solid pipe conveys collected water; properly designed subsurface drains intercept water in soil. Each needs a stable outlet and maintenance access.
Verify performance
Before covering work, check elevations, fittings, cleanouts, filter materials and outlet protection. Photograph the installation and keep a simple plan for future owners.
Questions to ask
- What information or assumptions is this plan based on?
- Who is responsible for locates, permits, survey control and inspection?
- What site condition would stop or change the work?
- How are quantities, changes and disposal documented?
- What records remain when the work is complete?
