When staff-level platting beats a 5-lot subdivision that triggers a public street

Question

Consider an owner holding 9 acres behind an existing small building, picked up years ago as part of a larger site and left in grass since. Planning tells them up to 4 lots goes through an administrative plat, staff level, no hearing, existing frontage counts, and roughly $8k to $12k of survey and engineering over a couple of months. Five or more lots pushes the project into a full preliminary plat, a public hearing, and a requirement for a public street with sidewalk, curb, storm, and a water loop instead of a dead end. A rough engineer's number for that improvement package runs $520k to $600k, with yield rising to about 11 lots. Lots in the area trade in the $70k to $85k range for the sizes being created. So the choice is 4 lots for almost no cost versus 11 lots for $600k of improvements plus a hearing that could be lost. The 11-lot version looks better on a spreadsheet and worse on every other axis, particularly for a buy and hold owner with no development staff. The variable most often underweighted here is carrying cost and execution risk across a multi-year hearing and construction timeline versus the near-certain, fast return on the administrative path.

The number worth having before anything else is what the remaining 5 or 6 acres are worth after carving off 4 lots along the existing frontage. If the administrative plat leaves the back acreage landlocked with no legal access, that isn't taking the small deal, it's killing the big one permanently, and the residual dirt ends up worth almost nothing. Ask the engineer to lay out the 4 lot version with a stub easement or a reserved 50 foot strip to the back, and see whether staff will still approve it that way. Some jurisdictions won't, they'll call the reserved strip evidence of phasing around the subdivision rules, and it varies a lot by ordinance. Whether 11 lots is worth $600k is a separate question. But the 4 lot version being cheap doesn't make it reversible, and that's the part worth nailing down first.
