What should an assessment cover?
A useful proposal explains three connected parts: where the system collects water, how it moves that water and where it releases it. A drain name alone does not describe a complete solution.
What to show the provider
Describe where water collects, when you notice it and whether the problem is new or recurring. Safe observations help frame the visit; they do not establish the cause.
- Note rain-related pooling separately from wet areas that appear during dry weather.
- Mention downspouts, patios, paths, recent landscaping and earlier drainage work.
- Bring any existing plans you already have; do not dig or enter water to investigate.
Ask for the reasoning, not just a product
Ask why the proposed approach fits the observed problem and what alternatives were considered. Request an explanation of the intended outlet and any limitations on using it.
Ask whether the proposal includes grading, surface collection, buried pipe, roof-runoff routing or separate specialist work. Not every assessment requires all of these. A yard drainage proposal is not a structural diagnosis.

Clarify approvals and property constraints
Identify who will check the property’s permitting authority, access restrictions and any applicable easements or HOA process. League City lists area drains and grade/fill work among permit-relevant projects; that example does not establish requirements elsewhere.

What to leave the visit with
Request a written scope describing the observed issue, proposed work, exclusions, restoration, maintenance and the provider’s price. Ask who will answer questions after installation. A drawing should help you understand the proposal; it is not permission to excavate.
If proposals differ, compare what each includes before comparing totals. Our proposal-comparison guide provides a checklist you can use without submitting personal information.
Assessment questions
Does an assessment commit me to installation?
Ask the provider about its visit fee, written terms and whether any later work requires separate acceptance. This guide does not book an assessment or set provider fees.
