A subdivision plan undone when the road standard changed mid review
A cautionary case on trusting a comp set built on entitlement work that was not fully understood. 62 acres at the edge of a growth corridor, two road frontages, in a county with a steady record of approving major subdivisions. Purchase at $540k, about $8,700 an acre. The plan: 14 lots of three to four acres, retail $62k to $75k, gross around $940k. An engineer's early estimate for road, drainage and entrance work comes in at $210k; underwriting builds in $260k and a 22 month timeline as a cushion. Eight months into preliminary review, the county adopts an updated road and stormwater standard. The submittal is in but not vested. The revised requirements push the internal road from a 20 foot gravel section to 24 feet paved with curb returns at the entrance, add a detention basin sized for a bigger storm event, and require a sight distance improvement at the intersection. The engineer's revised number comes back at $520k, survivable at a lower lot count on its own. The sight distance requirement is what actually ends the plan as designed. Meeting the new standard means cutting into the bank on the adjoining parcel, and the adjoining owner has no interest in selling a strip at any justifiable price. Four more months and about $22k go into alternative alignments before accepting that 14 lots is no longer viable. The fallback: withdraw the major plat, do a four lot minor split off the existing frontage where no new road is required, and sell the residual 46 acres to a farm operator. In: $540k purchase, $86k engineering, survey, legal and application fees, $78k of interest over 29 months, $19k of property taxes. $723k. Out: four lots for $268k, residual for $290k, less $28k of selling costs. $530k. Down $193k, plus 29 months. The mechanics worth carrying forward: buying land outright with a 60 day due diligence period and no entitlement contingency only works when approvals are genuinely routine, and "everyone says approvals are routine" is not the same as confirming it. A longer option, or a contract contingent on preliminary approval, shifts that risk to the seller rather than to a lender. Reading planning commission and board agendas going back two years before offering would have surfaced a pending ordinance rewrite that had been discussed publicly for a while. And exit comps on unapproved land should be underwritten as post-approval lots, which is what they actually are, not as evidence that approval is a formality.
