What should buyers ask about water movement on the exact lot?
Start with the lot, not the neighborhood. Walk the property and ask where roof water and surface water enter, cross, and leave. Look at the front, rear, side yards, driveway, patios, retaining walls, and the ground around each exterior wall. The question is not whether the yard looks dry during a showing. The question is whether the property has a clear path for water under the conditions the buyer can reasonably investigate.
Ask what the seller knows about ponding, erosion, drainage work, foundation work, retaining walls, gutter changes, downspout extensions, or repairs after heavy rain. Request the seller’s disclosures and any available invoices, reports, permits, surveys, or warranties that relate to water or foundation concerns. A prior correction may be useful evidence, but it does not prove that the condition is resolved today.
A survey may show drainage features, easements, swales, or other markings that affect the review. Read it with the property rather than assuming every line has the same meaning. If the survey and what you see do not match, record the difference and ask the appropriate professional or office to explain it.
Also note when the property was viewed and whether recent weather could affect what you saw. Dry conditions may hide ponding or a discharge problem, while wet conditions can make flow paths easier to observe. Record the limitation instead of treating one visit as a complete history of the lot.
Pete’s New Braunfels easement buyer questions guide can help you organize the document review. Keep the address, document date, source, and unanswered question beside each item. A clean record makes it easier to separate an observation from a diagnosis and a seller statement from an independently verified condition.
Which visible drainage clues belong in the inspection notes?
Document the conditions that show how water behaves around the house. Check whether the ground slopes away from the structure or directs water toward it. Note gutter and downspout discharge, low spots, swales, standing water, washed soil, exposed roots, staining, damp areas, and erosion. Look for retaining walls, patched areas, changed landscaping, or newer drainage materials that may point to prior work.
Check how water from the roof reaches the ground. A downspout that ends near a wall, a discharge path that crosses a walkway, or an outlet that sends water toward a low area deserves a written note. Do not state that a feature caused foundation movement from appearance alone. State what you observed, where it is located, and who should evaluate it.
Look beyond the property line. Neighboring lots, streets, driveways, construction, walls, and shared drainage paths can change where water travels. A low spot may collect water from more than one direction. A retaining wall may hold soil or affect runoff without being the only cause of a visible condition. Record the direction of flow and the conditions that need a closer review.
The inspection should also note visible cracks, movement, moisture, repairs, and access limitations without turning those observations into a foundation diagnosis. Pete’s New Braunfels home inspection problems guide provides a broader checklist for property-condition questions. Use it to prepare the inspection conversation, then let the qualified inspector or engineer address the meaning of the findings.
How should New Braunfels and Comal County records fit the review?
Use local records as a second line of evidence after you identify the exact property. The City of New Braunfels maintains drainage planning resources, design criteria, a Drainage Area Master Plan, a stormwater strategy, and floodplain information. The City also routes drainage complaints through Public Works. Those resources can help you frame questions about the property and the surrounding drainage context.
First confirm whether the property is inside New Braunfels city limits or in unincorporated Comal County. A property inside the city follows the City’s permitting and floodplain review path even when the address is in Comal County. For an unincorporated Comal County property, the Comal County Engineer’s Office administers regulatory floodplain development and provides parcel-specific resources. Ask the correct office what it can confirm for the address and whether an elevation certificate or another record is relevant. A general map or jurisdiction page is a starting point, not a property-level conclusion.
Do not treat a location outside a mapped special flood hazard area as proof that the lot has no flood or drainage risk. A flood designation and a foundation-drainage review answer different questions. One concerns mapped regulatory information. The other concerns how water moves across the actual lot, improvements, and nearby properties.
Put each record in the drainage log with the source, checked date, property identifier, and reason it matters. If a record is unavailable or uses a label you do not understand, write that down. Ask the City, County, inspector, engineer, survey professional, or closing professional which party can verify that specific item. Pete’s city-limits and Comal County comparison guide can help you identify the jurisdiction before you make the request.
What can a showing or flood map not tell a buyer?
A showing cannot establish foundation performance. It can reveal clues such as ponding, erosion, drainage discharge, repairs, or access problems, but those clues need the right follow-up. The same caution applies to a flood map. A mapped designation does not diagnose the foundation, and the absence of a designation does not settle every drainage question.
Use a qualified home inspection to document observable conditions. When the inspection or records raise a material concern, ask whether an engineer, drainage professional, foundation specialist, survey professional, or other qualified person should evaluate it. The right professional depends on the condition. A general inspection should not be treated as an engineering opinion, and a drainage complaint record should not be treated as a repair recommendation.
The option period creates a practical deadline for gathering information, but a blog cannot determine what the buyer’s contract allows or how a deadline applies to a specific transaction. Ask the buyer’s agent and the appropriate professionals which questions need answers before the relevant inspection or review deadline. Do not wait until closing to investigate a material water or foundation concern that was visible earlier.
After the inspection, compare the report with seller records, the survey, local records, and any specialist recommendation. Pete’s New Braunfels final walkthrough checklist can help with the later condition review. It does not replace the earlier drainage investigation or a qualified answer about an unresolved condition.
What should go in a four-column drainage log before making an offer?
Use four columns: observation or record, why it matters, who verifies it, and deadline. Under observation or record, list grading at each wall, roof runoff, gutter and downspout discharge, low spots, swales, ponding, erosion, retaining walls, neighboring runoff, visible repairs, survey markings, seller disclosures, City or County records, and specialist reports.
Under why it matters, describe the question without diagnosing it. For example, a downspout near a wall may require a runoff review. A survey marking may require an easement or drainage explanation. A prior repair may require the supporting report and invoice. A floodplain record may require parcel-specific confirmation. Use plain language that tells the next professional what needs attention.
Under who verifies it, name the City or County office, inspector, engineer, survey professional, foundation specialist, seller, supplier of the record, agent, or closing professional who owns the answer. Under deadline, write the date or transaction milestone by which the material question must be addressed. Mark each item verified, estimated, or unknown.
Resolve material unknowns before the relevant option-period deadline. If the sources conflict, keep the conflict open and ask the responsible professional to reconcile it.

The goal is a clear decision based on observed water movement, local records, and qualified follow-up rather than a confident guess from a single showing.
