What's on this agenda

Orange County commissioners hold a half-day retreat on two subjects for the county's Land Use Plan 2050 process: septic and wastewater treatment, and groundwater. An outside engineer presents on individual and community septic systems, addressing construction and maintenance costs and failure rates. An independent hydrogeologist presents on the county's water supply. He addresses how rock type affects wells, and whether a well can be tested before a zoning or building approval.

The board set this presentation schedule at an April 8 work session, as part of updating its Land Use Plan for the first time since 2008. This retreat and one set for November 21 bring in outside experts; the board covered other topics itself at work sessions in September, October and November.

Meeting recap

What happened, drawn from the records published after the meeting. Minutes

Orange County's commissioners spent a morning on November 14 on the two things that decide how much rural development the county can carry: septic and groundwater. The engineer who presented on wastewater told them the state has been steadily reducing what local health departments can say about system design, and that under the engineered option permit adopted eight or nine years ago, private engineers can design a system, stand in the place of the regulator, check their own drawings and issue the construction permit. State staff now review roughly 10 percent of large system designs; about 90 percent go the private route.

He was equally direct about the limiting factor. Suitable soil for on-site wastewater is in short supply in Orange County, and that reality is what limits rural development in this part of the piedmont. He called it a precious and limited resource.

How the votes went

No votes were taken. All seven commissioners were present.

    Presentation Environment and sustainabilityHousing and affordabilityLand conversion and large developmentStormwater and floodingWater and sewer
    A professional engineer with forty years in local land development presented on on-site and community wastewater systems. Key points: the engineered option permit lets private engineers design, self-check and permit systems, with state review now covering about 10 percent of large designs; suitable soil is scarce in Orange County and is the real constraint on rural development; installation costs run $9,000 to $75,000 for an individual four-bedroom home system and $20,000 to $60,000 a lot for community systems; community systems need professional management and inspection and give the county leverage to impose conditions, but concentrate failure risk and shift cost forward to the developer.…
  2. 2 Groundwater Resources
    Presentation Environment and sustainabilityHealth and human servicesWater and sewer
    A professional geologist presented on wells and groundwater. Community wells draw from confined aquifers, better protected from surface contamination than shallow wells, and are tested for far more constituents than private wells — including PFAS, radiologicals and organic and inorganic chemicals — where Orange County requires only coliform testing of a private well. There is no state requirement to test neighboring wells beyond 100 feet. He said the closer two wells sit, the more they influence each other, that a community well with usage limits and state review is more protective of sustainable drawdown than forty unregulated private wells, that original community wells often last more th…
