SUBJECT: HUNTER'S WAY ESTIMATED WATER USAGE
Property Owner: Virginia School Boards Association
Developer: john Flevarakis
Property address: 2330 Hunter's Way, Charlottesville, `A 22911
Acreage: 2.187 acres, TM 78 -49B1
Property Use
The proposed 12,000 square foot building's intended use is as a training facility for youth baseball. The
building will contain:
Workout area with treadmills, weights, etc. (approximately 5350 square feet)
Batting cage areas (approximately 6250 square feet)
Offices (approximately 400 square feet)
The water generating facilities at the building include 4 showers, 4 sinks, 2 urinals, 4 toilets, and 1 water
fountain. There is no kitchen or cooking area in the building.
The facility will be open from 9 am to 8 pm, Alonday through Saturday and 10 am to 5 pm on Sundays. The
peak rental times during the week are expected to be between 4 pm and 8 pm when children are out of school
and baseball practices meet. The facility will receive little use during the typical school /work day. The peak use
of the facility during the year is prior to and during the baseball season.
There will be 2 employees of the facility working all day and two additional employees will work during the
peak times and on the weekend days. This translates into 4 eight -hour employee equivalents.
Typically, a youth baseball team will "rent out" the facility which would include an average of 12 -15 children
and 3 -5 adults in the workout area for an average of 20 people in the facility. As one team finishes up and
another team comes in, there would be 40 people in the facility during the 15 -20 minute transition period. The
maximum building occupancy is not based upon the gross square footage because over half the building is a
low density use (batting cages). Showers are provided, but are used infrequently and typically by only the
adults. The owner operates a similar facility on public water and sewer in Charlottesville called Total
Performance. This facility is 8500 square feet and has 3 batting cages.
A second building on the lot (existing building) will be used for a contractor's shop and office
Total Performance
Estimated Maximum Daily Water Usage (based on VDH Guidelines)
Maximum Daily Water Usage from Employees:
4 eight -hour employee equivalents = 4 x 15 gpd = 60 gpd
Total Employee Estimated Water Usage = 60 gpd
15 gpd per employee is based upon Virginia Department of Health (VDH) regulations for water usage by
office employees)
2—
Maximum Facility Use Water Usage
June 18, 2008
The absolute maximum use of the facility would be for 11 rental time units in a day with 20 person use during
the rental time unit = 20 people per time unit x 11 time units = 220 people /day.
Based upon 2.5 gpd per occupant average water usage
Total rental participant water usage = 220 people x 2.5 gpd /person = 550 gpd
VDH does not have an estimated water usage for a baseball training facility. The above analysis is consistent
with water usage analyses previously submitted to and approved by VDH local and /or VDl i regional offices.)
Total Performance
Total Maximum Daily Water Usage = Max Employee Usage + Max Facility Usage
Total Maximum Daily Water Usage = 60 gpd + 550 gpd = 610 gpd
This is an estimate of peak water usage for a full facility operated at maximum capacity assuming all occupants
use water fixtures. actual water usages will be less than 610 gpd because the facility will not be rented out fully
and short duration visit times as associated with this facility (less than an hour) generate fewer water using
activities. For example, 4 hours of full facility rental will use a maximum of 260 gpd at published water usage
rates, but could be as low as 130 gpd if only half the occupants use water facilities.
Estimated Daily Water Usage (based on the existing facility usage per VDH GMP 35)
A second way to determine the estimated water usage at the new facility is to use average water usage at the
same or similar facility and use a 1.4 safety factor. This methodology is approved for use in estimated water
usage via VDH GNIP 35.

The new facility is approximately 50% larger than the existing facility. The expansion is mainly in the area
devoted to batting cages and circuit training so as to allow for a safer workout. Based upon VDH GIMP 35, the
existing facility would require an estimated water usage 212 gpd. The new facility would need to be designed at
a water usage of 318 gpd (212 gpd x 1.5 = 318 gpd) to handle the increased area of the new facility.
Auxiliary Building Water Usage
The auxiliary building will be used for a contractor's office and storage. The building will have 3 full time
employees occupying the building and 6 field employees that will be at the facility less than l hour per day.
3 eight -hour employee equivalents = 3 x 15 gpd = 45 gpd
6 field employees (count as 3 eight -hour equivalents)
3 eight -hour employee equivalents = 3 x 15 gpd = 45 gpd
Total Employee Estimated Water Usage = 90 gpd
15 gpd per employee is based upon Virginia Department of Health (VDH) regulations for water usage by
office employees)
Total Estimated Water Usage at the site per VDH regulations and policies would be:
Total Performance Building = 610 gpd (318 gpd)
Contractors Office = 90 gpd
Total Water Usage = 700 gpd (408 gpd)
Based upon previous discussions with the .Albemarle Health Department about the estimated water usage at
this site, 700 gpd would easily be approved (they thought the actual water usage would be less than this). Based
upon further calculations, according to strict adherence to VDH regulations and policies an estimated water
usage of 418 gpd would be approved by VDH and represents the most probable peak water usage at the site.
The water usage at the site will be far less than 2,000 gallons per day. A Tier III Groundwater ,Assessment is
adequate for the proposed project.
