Planning Board — August 20, 2025
Amherst Planning Board let two critical off-agenda issues go unanswered at the County Road subdivision hearing: a potential sixfold traffic increase on Thornton Ferry Road and an unresolved state scenic road law question that could give residents the right to a public hearing.
A complex, high-stakes 41-lot subdivision with unresolved stormwater, road safety, aquifer protection, and rural character conflicts produced direct board-applicant friction, strong public opposition that went entirely unaddressed, off-agenda legal and traffic issues of significant magnitude, and frank board admissions about the limits of local authority to protect community interests.

📋 AMHERST PLANNING BOARD — August 20, 2025
What happened at the County Road subdivision hearing — including what wasn't on the agenda
The Amherst Planning Board met Wednesday night to continue reviewing a proposed 41-lot residential subdivision on County Road (Bonded Properties LLC / Vonderosa Properties). The board's own chair described it as 'essentially a 55-unit subdivision' and 'a very significant change to a large tract of land.' The hearing continues September 17th at 7:00 PM — and there are several things every resident should know before then.
🚨 TWO SIGNIFICANT ISSUES CAME UP THAT WERE NOT ON THE PUBLIC AGENDA:
1. TRAFFIC ON THORNTON FERRY ROAD: A resident presented data at the meeting showing the development would generate approximately 619 additional car trips per day — onto a road that currently handles about 570 cars per week. That's roughly a sixfold increase, with obvious implications for pedestrian and cyclist safety. This was not listed on the agenda, so residents who live on or use Thornton Ferry Road had no specific reason to attend. The board offered no response to the data presented.
2. SCENIC ROAD LAW: Resident Nancy Williams raised a specific legal question — whether RSA 231:157-158, New Hampshire's scenic road statute, applies to the planned road improvements. If it does, it would require a public hearing and planning board consent before trees or stone walls are removed. The board did not address this question. Residents may have statutory participation rights that have not yet been acknowledged.
⚠️ OTHER UNRESOLVED CONCERNS FROM THE MEETING:
• AQUIFER PROTECTION: The subdivision sits on what a board member called 'the lone remaining aquifer in town.' The applicant wants to defer stormwater management plans until the building permit stage. A board member called deferring that review 'irresponsible,' noting you cannot properly size detention basins without knowing what will be built on individual lots. No final decision was made — this goes to September 17th.
• ROAD CONDITIONS DURING CONSTRUCTION: The board is debating whether homes can be occupied before County Road is fully paved. One board member said leaving a widened dirt road for potentially eight years during phased construction is 'stupid and not the way it's done.' No binding requirement has been set yet.
• DEVELOPER CREDIBILITY: A public commenter alleged that the developer broke previous commitments — building a 6-bedroom house after promising 3-4 bedroom homes — and raised concerns about alleged unpermitted tree removal and construction near wetlands. The board did not respond to these allegations.
• STATE LAW LIMITS LOCAL CONTROL: The board chair stated plainly that 'there is not local control over development — there is statewide imposition insisting on more development,' and that municipal land purchase may be the only way to prevent this type of project. Residents deserve to understand this constraint — and to ask whether the town should be exploring that option.
The next hearing is September 17th at 7:00 PM. If you live near County Road, Thornton Ferry Road, or simply care about Amherst's aquifer and rural character, this is a meeting to attend.
Public impact
41-lot subdivision (characterized by board as effectively 55 units) generating an estimated 619 additional vehicle trips per day, impacting the town's last remaining aquifer, altering rural road infrastructure, and permanently transforming a large undeveloped tract
Nine culvert installations/replacements, drainage improvements, fire cistern, and 50-foot right-of-way dedication required; road deemed currently inadequate for development, with risk of years of unpaved widened road if phasing is not properly conditioned
Topics discussed
Continuation of public hearing for proposed 41-lot subdivision on County Road. Applicant presented revised proposal dropping some previous requests while maintaining key asks regarding stormwater plan timing and bonding alternatives.
Debate over timing of stormwater plan submissions, with applicant requesting deferral until building permit stage. Board members expressed concerns about missing stormwater details including erosion controls, detention facilities, and outfall locations. Later discussion questioned how detention basins and water management systems can be properly sized without knowing details about individual lot development plans.
Discussion of proposed County Road improvements including 9 cross culverts (4 replacements, 5 new), drainage improvements, fire cistern installation, and dedication of 50-foot right of way. Road currently deemed inadequate for development without improvements.
Applicant proposed 50-foot woodland buffer along County Road frontage to preserve rural character, with restrictions on tree removal except for driveways and diseased trees. Board raised concerns about clearing limits on remainder of lots and later discussed revised buffer language and concerns about property owners' rights within the buffer area.
Discussion of 35.5 acres proposed for conservation (14.5 acres buildable upland) and 10-foot pedestrian trail easement. Board member suggested increasing trail easement to 20-25 feet for construction purposes.
Extended debate about whether houses can be occupied before road is fully paved, with concerns about maintaining a widened dirt road for years versus requiring base pavement before occupancy.
Board discussion of numerous technical items still needed before approval, including stormwater calculations, septic plans, and stone wall preservation details. Later discussion covered various missing details including stump disposal methods and debate over whether extensive upfront information should be required for this large project.
Discussion of bonding requirements for individual lot stormwater management, with applicant preferring to use certificate of occupancy withholding instead of surety bonds.
Public comment highlighting that 619 additional cars per day from the development would severely impact Thornton Ferry Road, which currently handles 570 cars per week.
Public comments criticizing the project's impact on rural character, noting the developer has built a 6-bedroom house despite promises of 3-4 bedroom homes.
Debate over whether individual lot stormwater plans should be reviewed by the Planning Board or delegated to staff and third-party engineers as conditions precedent.
Board member requested more detailed information about how stone walls on the development site will be addressed, expressing dissatisfaction with vague commitments to 'do our best.'
Correction made to minutes regarding Supreme Court remand language, clarifying that the court required reconsideration under certain guidelines, not approval of 39 units.
