Re: DRAFT Tier III Groundwater Assessment — "Key Findings" for Albemarle Co. Parcel #45-59M
HydroGeo Project #18-374
Dear Luke,
At your request, HydroGeo Environmental, LLC (HydroGeo) is submitting a DRAFT Tier III Letter Report
for Albemarle County Parcel #45-59M (the "Site — see attached figure for Site location). This DRAFT
outlines Key Findings of the study, to be included as part of the Special Use Permit application package.
The full report will be submitted to Albemarle County with the final Site Plan.
Key Findings:
Albemarle County hydrogeologic unit: Piedmont Foothills (Hydrogeologic Unit III)
Groundwater availability zone: Class II (medium relative groundwater availability)
Hydrogeologic conditions favorable to proposed use? Yes. However, precise well yields will remain
unknown prior to drilling. Virginia Department of Health (VDH) has not yet provided well completion reports
for nearby properties (FOIA request submitted 12/4/18) — this information will help estimate average well
yield in the Site vicinity to refine our recommendations on a groundwater supply development strategy
moving forward.
Site within groundwater sensitivity zone? No. Review of the Virginia Department of Environmental Quality
(VADEQ) Virginia Environmental Geographic Information Systems (VEGIS) viewer and Albemarle County
GIS did not identify any open pollution complaint cases within the required 1000-foot search radius.
Groundwater flow pattern: Groundwater recharge areas include vegetated land onsite and undeveloped,
permeable areas located upgradient of the Site; groundwater discharge areas occur along the southwestern
edge of the Site, along the intermittent streambed of the unnamed tributary to Schroeder Branch, a tributary
to the Rivanna River South Fork. General groundwater flow in the vicinity of the Site is assumed to be
influenced by topography and likely follows a net southwest- to southeast direction toward the unnamed
tributary to Schroeder Branch along the southwestern edge of the parcel and then flows southeast to
Schroeder Branch.
Contamination threats on record: One (1) VPDES outfall was located within the required 1000-foot search
radius from the parcel boundaries. Due to its location approximately 950 feet away and downgradient of
the Site, and the knowledge that registered VPDES permitted discharge is regulated and monitored by state
agencies, HydroGeo does not consider this to be likely contamination threat, nor a reason to place the Site
within a groundwater sensitivity zone.
Additional contaminant threats observed in field reconnaissance? Field reconnaissance has not been
performed at this time.
Impacts of proposed use on existing users: Proposed groundwater use should be adequate for the
development's needs without unreasonably affecting users offsite.

Albemarle County Parcel #45-59M December 7, 2018
BMP recommendations: Maintain vegetated stream buffer as much as possible during development;
implement runoff -neutral site plans insofar as practicable.
It should be emphasized that these are preliminary and draft findings, thus they are subject to change.
Best regards,
Ernest Beasley, CPG
