Six Lots, a Lake Shore, and a Prior Subdivision
Your client Ted Wheelock owns 30 acres on Lake Elmore in a town that has both zoning and an approved town plan. He wants to subdivide into six building lots, drill one shared well, install a mound septic system on each lot, and replace a 1950s seasonal camp with a year-round house. In 2022 he subdivided the same original parcel to create four lots, two of which now have houses on them. Access to the new lots would be over a Class 4 town road. Several proposed lots would sit within 150 feet of the lake's mean water level, and Ted wants to log and clear the shoreline lot this fall and "pull the permits afterward."
1. Is this subdivision likely to need an Act 250 permit? How do you analyze it?
Read the worked answer
Likely yes - because the lots aggregate.
- Act 250 jurisdiction for subdivisions turns on the number of lots created within a five-year window, not just the current application. Four lots in 2022 plus six now equals ten lots in the same five-year period, which meets the ten-lot subdivision threshold. Confirm whether the retained parcel also counts toward the total, and confirm the exact dates of the 2022 conveyances.
- The town's zoning and plan matter: where a municipality has both, the higher ten-lot threshold applies; where it lacks one or both, lower thresholds can apply. Here the town has both, so the standard threshold governs - but the aggregation point stands.
- Process: apply to the District Environmental Commission before creating the lots. The commission reviews the statutory criteria - water and air, soil and septic capacity, traffic and access, municipal services, aesthetics, and shoreland impact.
- Practical advice: clearing or improving before the permit issues is a violation and can be used against him. The lots cannot be marketed or conveyed as approved lots until the permit and any local subdivision approval are in hand.
- Do not let him assume that a 30-acre parcel means "six lots for sure."
2. What water and wastewater approvals are needed for the shared well and the mound systems?
Read the worked answer
A Wastewater System and Potable Water Supply Permit from the Agency of Natural Resources is required, and the design work must be done by licensed people.
- Vermont regulates both wastewater and potable water supply under 10 V.S.A. chapter 64 and the associated rules. The permit must be obtained before construction of the mound systems and before the shared well is installed or used.
- Site work comes first: test pits and percolation/soil evaluation by a licensed designer to establish that each lot has an acceptable disposal area and replacement area, with proper setbacks from the lake, wells, and property lines. Lots that fail soils may need to be reconfigured or dropped.
- The shared well must meet potable water supply requirements (isolation distances, yield, water quality testing). Sharing a well across lot lines requires an easement or shared-supply agreement recorded against all lots.
- The existing camp's outhouse or cesspool must be addressed: abandoned systems must be properly decommissioned, and converting to year-round use triggers review of the existing system as well.
- Local zoning will also impose lot size, setback, and shoreline requirements on top of the state permit.
3. Ted wants to clear the shoreline lot this fall and permit later. What should you tell him?
Read the worked answer
Stop. Two separate approvals govern that clearing, and both are before-the-fact.
- Vermont's Shoreland Protection Act (10 V.S.A. chapter 49A) requires a state shoreland permit for clearing vegetation and for creating impervious surface within 250 feet of the mean water level of a protected lake. His lots at 150 feet are squarely inside the protected shoreland. A shoreline permit would set limits on clearing, impervious coverage, and vegetative buffers.
- Act 250 will also examine shoreland and water-quality impacts of the subdivision, and unauthorized clearing can become an enforcement exhibit against him.
- Separately, the Class 4 town road raises an access question: the town has no duty to maintain a Class 4 road, and new driveways and access points commonly need town approval and a state access/utility permit. He should confirm legal, passable access before promising it to buyers.
- Advise him to sequence it: soils and survey, local subdivision/zoning approval, Act 250, ANR wastewater and water supply permits, then shoreland permit and access permits, then clearing and construction. Advise that he consult counsel on any clearing already done, since enforcement exposure can be retroactive and expensive.
