Virginia Tech review finds Greene County water/sewer model generally prudent but flags omitted units and short‑term risks

Dr. Cheryl Bailey, a visiting professor at Virginia Tech's Institute for Policy and Governance, told the Greene County Board of Supervisors that her team's limited review of the county's water and sewer financial model focused on the housing-start assumptions underlying a proposed water reservoir project and found the model to be "reasonable and prudent" given the data the reviewers examined.

The Virginia Tech team examined planning documents and projects the county identified as having "current activity," visited the proposed reservoir site and treatment plant, and compared local trends with state and national demographic and economic indicators. "We reviewed the history of the water reservoir project," Bailey said, and described a multi-decade effort tied to the state's regional water supply planning requirements that followed the severe 2002 drought.

The review included a technical amendment: one project's record of approved units was updated such that the net change was 64 approved units. Bailey said those 64 units were outside the model as presented to her team and that "the analysis and finding conclusions...remain unaffected." She told supervisors the model intentionally omits some approved residential projects and all commercial and nonresidential projects with current activity; that omission, she said, creates a "buffer" or "insurance" below the line if buildout is slower than expected.

Bailey said the model also applies further conservatism in later years: the team calculated that within the first five years of current-activity projects (2025''29) the average pace is roughly 300 total units (residential, commercial and nonresidential), and the annual average declines to about 200 in a later period the report models. "By prudently excluding a portion of the residential projects and excluding the commercial and nonresidential projects with current activity, there's a buffer and insurance built into the model," she said.

The presentation noted broader context: Greene County has shown faster population and economic growth than the state in recent years, the Charlottesville region has a tight housing supply (low months of supply and low median days on market) and the region has growing defense-technology activity that could drive housing demand. Bailey also emphasized long lead times for major water infrastructure and the system's existing deferred maintenance and reliability liabilities.

During Q&A, board members and attendees raised fiscal and demand risks. Dr. McLigan asked whether the model accounts for higher mortgage rates and falling first-time-buyer activity; Bailey replied that despite those headwinds demand has remained strong and that the model's underlying project list and conservative assumptions address some downside risk. She also said her team did not analyze the county's financing plan itself; that work is being done by the county's registered municipal adviser, Davenport & Company, and was intentionally left outside Virginia Tech's scope.

Several public speakers and an outside reviewer presented alternative analyses during the same meeting. Ken Copeland and a table prepared by Scott Mingledorff using the Virginia Tech population projections asserted that if the county uses Virginia Tech's population-derived housing-start estimate (about 87 units per year, roughly 2,350 new units 2030'150) and the county's funding model, the plan would produce a roughly $33 million shortfall by 2034 and a larger 30-year deficit unless EDU (equivalent dwelling unit) fees or housing starts are materially higher. Copeland said raising EDUs to roughly $19,350 would balance long-term debt service under the lower housing-start scenario but would leave a near-term shortfall to be addressed.

Other public commenters urged the board to proceed with the reservoir to protect water reliability and public safety; one commenter pointed to recent high-profile water outages elsewhere as evidence of risk. Board members and staff noted the tension between the review's conclusion that the model is conservative in some respects and the independent analyses showing vulnerability to lower housing growth or slower near-term buildout.

Who said what: the presentation and most of the technical detail came from Dr. Cheryl Bailey (Virginia Tech); questions were asked by board members during the meeting and by several public commenters, including Ken Copeland, Scott Mingledorff and Jim Higgins, who recommended revisiting EDU fees. The county's municipal adviser, Davenport & Company, was identified as the firm that prepared the financing plan and remains responsible for the debt/underwriting work.

What it means: the Virginia Tech review validates the county's approach as not unreasonable given the documents and projects identified as having current activity, but it also documents that the model excludes some approved projects and commercial activity (which the reviewers called a conservative design choice). Independent town-hall commenters and an alternate spreadsheet analysis using Virginia Tech's population projection warned that using lower housing-start assumptions produces sizable short-term funding gaps and would require either higher EDU fees, a larger share of general-fund support, or phasing changes.

The board did not adopt a financing decision at the meeting. Bailey urged the supervisors to weigh the long lead times and public-safety importance of water reliability alongside the financing choices; other presenters urged prompt action to protect permits that have expiration deadlines. The county staff and advisors will continue follow-up work and provide more detailed financial scenarios to the board and public.

Ending: Greene County now has both an independent academic review that finds the water/sewer model defensible under its stated assumptions and separate, public analyses that show the county's financing plan is sensitive to lower housing-start rates. The supervisors indicated they will continue studying alternatives, including EDU adjustments and phased construction, as they link the reservoir decision to the county's budget process.
