Site Drainage Planning
A drainage plan for a mobile home is not a generic sketch or a promise that water will never collect. It is a project-specific way to coordinate the proposed home, grading, runoff, outlets, erosion controls, access, utilities, and neighboring property before and after site work, and the plans and permits will name the home a manufactured home.
Short answer: Start with the approved home location and current site documents, then ask the responsible local authority and qualified site professional what drainage information the project needs. A grader can price a defined scope, but should not be expected to invent an outlet, approve off-site discharge, diagnose soil, or replace engineering when professional design is required.

Buying land for a mobile home? The Land Check reads the county's own permit rules for the one parcel you give us, and says where each answer came from and when.

Start with the exact property, quote, record, or job detail behind your question. Mark what is confirmed, what still needs a current source, and who must answer it. Use the checklist to keep the next call, document, or decision clear.
Separate existing water patterns, proposed grading, roof runoff, driveway drainage, erosion control, and final stabilization.
Use the current survey or site plan, approved home location, utility and wastewater areas, access route, photos, and local requirements as inputs.
Keep design, discharge, soil, retaining, flood, watershed, and approval decisions with the responsible authority and qualified professionals.
Step 1
Gather the survey or site plan, proposed home footprint, elevations if available, driveway, utilities, wastewater and water areas, visible drainage features, photos, and authority contacts.
Step 2
Ask which plan, permit, review, inspection, stabilization, outlet, or professional-design questions apply before grading begins or changes are authorized.
Step 3
Put grading, drainage, erosion-control, delivery-touch-up, inspection, and final-stabilization responsibilities in writing, then preserve dated photos and closeout records.
Details to Sort
The plan or documented scope should show how site work relates to the home area, access, utilities, erosion control, stabilization, and a lawful or accepted receiving path. The exact required document can vary by site and local program.
The homeowner gathers records and assigns written scopes. A surveyor addresses retained survey work. A grading provider performs defined earthwork. An engineer or other qualified professional handles retained design or evaluation. The local or state authority administers its review and inspection lane. The setup provider supplies installation-area inputs within its scope.
Have the parcel and jurisdiction, survey or site plan, proposed home location and dimensions, available elevation or contour information, driveway and delivery route, utilities, wastewater and water areas, flood or watershed records, photos in different weather, permits, and all written site-work scopes.
Ask what document controls; who confirms the outlet; how roof, driveway, uphill, utility-trench, foundation-area, and neighboring-property questions are handled; what remains visible; what must be stabilized; who returns after delivery; and what evidence closes the scope.
Topography, access, cut and fill, unsuitable or wet material, rock, off-site material, drainage structures, erosion controls, stabilization, weather, professional services, review timing, delivery disturbance, utility trenches, and change orders can affect cost and sequence.
Common mistakes include using a generic pad dimension, treating a level-looking surface as a drainage answer, assuming runoff can be sent across another property, leaving roof water or driveway work out of the scope, covering work before review, and failing to assign final grading and stabilization.
My Manufactured Home Guide does not design drainage, determine a lawful outlet, diagnose soil or water, set grades, approve fill, evaluate a retaining condition, establish property rights, or predict a permit or inspection result. Use the actual project documents, responsible authority, and qualified professionals.
Manufactured Home Land Check
A Manufactured Home Land Check can organize known parcel, topography, flood, access, utility, wastewater, water, and site records. It does not design drainage or determine site approval.

A wet area, ditch, seep, low point, or prior erosion mark is useful evidence, but it does not identify the cause or safe corrective design.
Next step: Record the location, date, recent weather, photos, and direction of visible flow, then give that evidence to the qualified site professional and responsible authority.
That phrase may not identify plan source, outlet, quantities, erosion measures, roof-water handling, driveway work, stabilization, return trips, or professional design.
Next step: Ask for the exact included work, controlling documents, exclusions, allowances, inspection points, and finish condition in writing.
Delivery and setup can disturb the approach or home area, while roofs, gutters, utility trenches, decks, skirting, and final grade can change how water is observed.
Next step: Compare current conditions with the accepted plan and written scopes; send concerns to the responsible provider or authority without changing or concealing work that still needs review.
No. The required information and review path depend on the site, jurisdiction, disturbed area, topography, soils, flood or watershed context, home location, utilities, access, and local program.
A grading provider can perform a defined retained scope, but outlet, design, property-right, environmental, authority, or engineering questions may require other qualified parties and current approvals.
Without entering unsafe areas, record the date, recent weather, visible water locations, erosion, ponding, roof or downspout discharge, driveway and ditch conditions, and wide-context photos. Those observations do not diagnose the cause.
