Site drainage and grading due diligence for Michigan IRA property

A dry yard can hide a drainage problem. Water may collect only during a hard rain, when snow melts over frozen ground, or after leaves block an inlet. A shallow swale can look like an uneven lawn until someone fills it, and a buried pipe can carry water away until one crushed section backs up beside the foundation. Site drainage due diligence needs to follow water across the property, not judge the ground from one clear afternoon.

For a self-directed IRA buyer, the findings also need a workable repair and payment plan. The account may need to fund an engineer, survey work, cleaning, excavation, permits, or restoration before the next wet season. That plan should not depend on the IRA owner digging a trench, buying pipe personally, or paying a contractor while waiting for the custodian to respond.

Build the site record before walking the grade

Start with the survey, legal description, title commitment, recorded easements, approved site plans, grading and drainage drawings, soil or geotechnical reports when available, and permits tied to prior earthwork. Add contractor invoices, drain-cleaning records, photographs, insurance repair records available to the buyer, and seller or property-manager notes about ponding, erosion, seepage, backups, washouts, or neighbor concerns.

Match each document to the present site. A plan can show a swale that was later landscaped flat. A permit may cover an addition without showing work performed beyond its stated scope. An invoice for a new drain may identify the pipe but omit the outlet. Keep proposed, approved, installed, and observed conditions separate until the buyer's professionals reconcile them.

• Current survey, legal description, title commitment, and recorded drainage or access documents
• Approved grading, drainage, utility, landscape, parking, and site plans
• Permits, final approvals, inspection notes, engineering reports, and contractor records
• Maintenance history for inlets, catch basins, culverts, pumps, swales, ponds, and buried lines
• Dated photographs and reports for standing water, erosion, basement seepage, pavement settlement, or prior repairs

Walk the route from high ground to the outlet

A useful site walk begins beyond the wet spot. Mark the high and low areas, roof discharge points, pavement slopes, retaining walls, swales, ditches, inlets, culverts, sump or footing-drain outlets when known, and every place water leaves or enters the parcel. Compare the measured boundaries with the route water appears to take. A low area near a lot line may depend on an easement or a feature on neighboring land.

Look for sediment fans, water lines, washed mulch, exposed roots, dead turf, algae, rust staining, silt inside structures, patched pavement, soil against siding, and repeated sealant or coating work. Indoors, connect the site map with basement staining, crawlspace moisture, sump activity, damaged finishes, or musty areas. Those observations show where to investigate; they do not establish the source by themselves.

West Michigan weather can change the answer from one visit to the next. Snow can hide inlets and settlement. Frozen soil can send meltwater across a route that absorbs rain in summer. Dense vegetation can conceal a ditch or outlet, while a long dry period can erase the visible edge of ordinary ponding. Record the date, recent weather, ground condition, access limits, and what could not be tested. When drainage is material to the purchase, a second visit during or soon after wet conditions may be worth arranging through the contract process.

Separate surface water from the problems below it

Water beside a building can come from grading, roof discharge, irrigation, a plumbing leak, a failed sump line, a damaged sanitary sewer, groundwater, or more than one source. A wet basement does not prove the yard needs regrading. A soggy lawn does not prove a drain is broken. Ask the inspector, drainage professional, plumber, roofer, foundation specialist, or engineer to define the likely source and explain which evidence supports the conclusion.

Keep the scopes connected without blending them together. A roof contractor can document where downspouts discharge. A sewer camera may show a damaged pipe. A surveyor can measure elevations and locate improvements within the agreed assignment. An engineer can evaluate a drainage design. The buyer's attorney and title professional can interpret recorded rights. None of them should be treated as answering every water question on the property.

This distinction matters when pricing repairs. Extending a downspout is different from rebuilding a failed underground line. Cleaning an inlet is different from correcting pavement that drains toward a doorway. A basement coating may change the visible interior without correcting water that still reaches the wall. Put the suspected cause, test, finding, and proposed response in one issue log so a cosmetic repair does not close the wrong question.

Inspect each drainage feature as part of a route

Map every visible component and ask where it begins, where it ends, who maintains it, and what happens if it stops working. Swales need a continuous route and an outlet that the property can lawfully use. Inlets and catch basins need a discharge path. Culverts need open ends and enough surrounding support. Detention or retention areas may have control structures, side slopes, vegetation, sediment, access, and maintenance duties that are not obvious from the water's edge.

Buried systems call for more than a guess at the pipe direction. Ask for plans, installation photographs, locating records, cleanout locations, prior camera work, repair invoices, and discharge approvals. When a focused inspection is recommended, define whether the professional will open structures, trace lines, use a camera, test pumps, measure elevations, or observe flow. The report should identify which sections were confirmed and which remained inaccessible.

Review paved areas with the same route in mind. Settlement around a catch basin, wheel-path ruts, cracked curbs, patched trenches, raised sidewalk panels, and water marks at entrances can show where grading or subsurface work deserves attention. Do not turn one puddle into a full paving diagnosis. Ask the qualified professional whether the concern is maintenance, localized failure, utility settlement, base or subgrade movement, an undersized drainage feature, or a broader site-design issue.

Use maps as screens, then verify the ground

Online parcel, elevation, flood, soil, and wetland maps can help a buyer decide which records and professionals to request. They do not replace a current survey, field measurements, pipe investigation, or property-specific regulatory review. Map layers may use different dates and scales, and a line on a screen may not match a feature's precise location on the ground.

Michigan EGLE says its Wetlands Map Viewer provides potential and approximate wetland locations. The agency says the viewer is not intended to determine specific wetland locations or jurisdictional boundaries and points to on-site evaluation by EGLE or a qualified consultant for jurisdictional determinations. A map screen should therefore open a due-diligence question, not close one.

If the proposed grading, outlet, driveway work, pond work, or drain repair reaches a mapped or visibly wet area, waterbody, roadside ditch, shared system, or neighboring parcel, identify the responsible authorities and property rights before designing the fix. The buyer's engineer, surveyor, attorney, and applicable agencies should determine what can be built, where it can discharge, and which approvals belong in the schedule.

Read drainage rights beside the physical system

A working outlet is not enough if the property lacks the right to use or maintain it. Compare pipes, ditches, swales, ponds, culverts, shared drives, and access routes with the survey, title exceptions, recorded easements, site plans, and maintenance agreements. Ask who benefits, who pays, who may enter for service, whether the route can be relocated, and what notice or approval is required before work begins.

Also identify public and private responsibilities. A feature near a road may involve a municipality, county road agency, drain office, private association, utility, or adjoining owner, depending on the location and documents. Do not assume that a public-looking structure will be repaired with public funds or that the property may connect to it. Get the answer for the exact feature and address in writing when the purchase depends on it.

Maintenance access belongs in the operating budget. A buried outlet beyond a fence, a basin reached only across tenant parking, or a culvert shared with another parcel can make routine work slower and more expensive. Record keys, gates, notice requirements, equipment access, vegetation limits, snow storage, and restoration duties before treating the system as easy to maintain.

Confirm permits before changing the grade

Michigan EGLE's Soil Erosion and Construction Stormwater page says Part 91 provides for erosion control and protection of adjacent property and state waters from sedimentation. It states that a permit is generally required for an earth change disturbing one or more acres or located within 500 feet of a lake or stream. Those are general state thresholds, not a complete approval checklist for one project.

A smaller project may still need local grading, right-of-way, drain, building, floodplain, wetland, utility, driveway, or site-plan review. The responsible office can vary by city, village, township, county, road authority, drain district, and the exact work. Ask each authority what records it holds, what it regulates, and what final documentation will show that approved work is complete. Do not let one permit stand in for every other review.

Check past work as well as the proposed repair. Compare permit files and final approvals with filled low areas, added pavement, new walls, relocated outlets, altered ditches, and recently landscaped slopes. A missing record does not prove the work was unlawful, and a closed permit does not establish present performance. It gives the buyer's attorney and technical professionals a specific gap to investigate.

Turn findings into a complete repair scope

Ask bidders to price the same written findings and design. Include surveying or engineering, utility locating, excavation, pipe and structures, pumps or controls, erosion measures, dewatering when needed, pavement or landscape restoration, permits, inspections, testing, cleanup, and closeout records. The scope should say how hidden conditions, undocumented utilities, unsuitable soil, or a blocked off-site outlet will be handled before a change order proceeds.

Sequence the work across trades. Regrading may affect siding clearances, steps, accessible routes, retaining walls, utilities, wells, septic components, landscaping, fences, parking, or neighboring drainage. A new paved surface may change runoff. A wall repair may need temporary drainage. Have the engineer and relevant professionals decide the order rather than asking separate contractors to solve only the piece in front of them.

Separate immediate cleaning or stabilization from permanent correction and routine maintenance. Put each accepted item into the account budget with taxes, insurance, management, utilities, vacancy, and other property work. Do not make a known drainage cost disappear by assuming higher rent, full occupancy, appreciation, insurance proceeds, refinancing, or lower future maintenance. None of those outcomes is guaranteed.

Plan occupied work around lawful access

At an occupied property, drainage inspection and repair may affect yards, parking, entrances, deliveries, utilities, noise, mud, equipment routes, and access to tenant-controlled areas. The property manager and Michigan attorney should review notice, entry, lease duties, temporary routes, communication, and accommodation requests before a schedule is promised. The contractor controls the work zone, but the housing provider remains responsible for its legal procedures.

HUD states that the Fair Housing Act prohibits housing discrimination because of race, color, national origin, religion, sex, familial status, or disability. Use consistent procedures for inspection access, repair priorities, temporary measures, communication, and accommodation review. Base decisions on documented site conditions, lease rights, qualified recommendations, and applicable law rather than protected characteristics of tenants or neighbors. Michigan and local protections may also apply.

Keep the work inside the IRA process

Ask the self-directed IRA custodian how surveys, inspections, engineering, contractor deposits, permits, emergency work, repairs, refunds, insurance proceeds, and later maintenance must be approved and paid. Confirm the purchaser name, authorized signer, invoice wording, funding lead time, and change-order process. If the seller will complete work before closing, have the purchase agreement define the design, scope, contractor qualifications, access, permits, inspections, completion records, and buyer verification.

Current IRS guidance says there is no list of approved retirement-plan investments. It also identifies furnishing goods, services, or facilities between a plan and a disqualified person among prohibited-transaction concerns and describes improper use of an IRA by its owner, beneficiary, or another disqualified person. A completed drainage repair, custodian administration, or real estate closing is not IRS approval of the property or strategy.

Do not assume the IRA owner can clear an inlet, dig a test hole, reshape a swale, run equipment, supply materials, direct personal labor, or pay a vendor and seek reimbursement. Have the custodian, CPA, and attorney review the people, work, contracts, signatures, and money flow before anyone acts. The correct account procedure may also affect how quickly an emergency washout or pump failure can be addressed after closing.

Put wet-weather questions on the offer calendar

Drainage review can require records from several offices, lawful site access, survey measurements, line locating, cleaning, camera work, engineering, permit questions, and contractor estimates. Start early enough to understand the route and price the accepted condition before the applicable contingency expires. A seller's promise that the yard is usually dry should not replace records and field work when drainage affects the purchase decision.

• Map every visible inlet, outlet, swale, culvert, low area, pump discharge, and roof connection
• Assign each unknown route, property right, permit, and maintenance duty to the professional or authority responsible for the answer
• Record inspection limits and decide whether wet-weather observation or added testing is needed
• Connect every accepted condition with a written scope, budget, custodian procedure, and post-closing owner
• Keep contract notices and repair agreements in the form and delivery method the buyer's attorney requires

No property, drainage system, map, permit, repair, ownership structure, or strategy is approved or endorsed by the IRS. Have your own self-directed IRA custodian, CPA, Michigan attorney, surveyor, engineer, property inspector, title and insurance professionals, qualified contractors, property manager, applicable public authorities, and other advisors review the account, land, records, occupants' rights, proposed use, and transaction before taking action.

Leave closing with a drainage file that can guide maintenance

Keep the survey, elevation and site plans, drainage map, inspection reports, dated photographs, permits, final approvals, recorded easements, maintenance agreements, cleaning records, engineering documents, scopes, estimates, contractor credentials, tenant communications, custodian instructions, and closing documents together. Mark every buried route, outlet, or low area that was not confirmed. Add service dates and the contacts responsible for shared or public features.
