LIGHTING
June 18, 2013
Full Design Review Board Meeting
LOCATION
Brown’s Chapel #1
PURPOSE
• Increase playability of field and park – enhance baseball presence
• 40% increase in “player hours”
• BC1 accommodates 60, 65 and 70-basepath games
•
broader set of skill levels can use one field
• Lighting will add greater scheduling flexibility
• Easier to make up practices and games
• More home games – less driving for Reston parents/volunteers
• Provides the “under the lights” experience to younger players
• Ability to host some tournament games
• Light lower parking lot for safety of Chapel and field users –
DEFERRED FOR FURTHER STUDY
PROPOSAL SUMMARY
• Install six 60-foot high light poles, each with 3 1500W fixtures
• Install service panel to back of concession stand, with exterior to
match existing – insulated for sound if necessary
• Install underground service from drop along Baron Cameron
Avenue overhead line to concession stand
• Install scoreboard
DRB COMMENTS FROM
APRIL 16, 2013 MEETING
• Example of ball field lighting which more closely replicates
the proposed lighting to use for comparison
• Balloon flight documentation/photos at height of proposed
poles in proposed locations
• Installation of a test light, if feasible
• Schedule of the games and/or quantified impact of
proposed lighting (i.e. spreadsheet showing beneficial
impact of lighting on schedule)
RESPONSES
• “Example of ball field lighting which more closely replicates
the proposed lighting to use for comparison”
• Only one field, in Purcellville, VA has the 6-pole set up
• Vast majority of 200-foot outfield ball fields use a
4-pole set up
• Attempted to photograph lights here on Friday, May
10 when only that field was lighted – only two nights
where this was even possible
• Unsuccessful due to major thunderstorm after arrival
LIGHT DISPERSION
• Ideal aiming angle is between 25° & 30°
• Typical baseball mounting heights are 60-ft to 85-ft
• Choosing poles that are too short will increase glare for
players and increase undesirable offsite spill light
• More poles permit steeper lighting angles as each fixture
covers less of the field

RESPONSES
• “Schedule of the games and/or quantified impact of
proposed lighting (i.e. spreadsheet showing beneficial impact
of lighting on schedule)”
• Show Reston Little League response to scheduling
questions (separate Power Point presentation)
• RA, RLL and Newport Shores Cluster Association met to
discuss scheduling
ADDITIONAL INFORMATION
• During its meeting of May 23, 2013, the Reston Association Board of
Directors approved a motion that the Browns Chapel Park Ballfields
#2 and #3, as are shown on the attached site graphic, continue to be
for use only during daylight hours and that the Reston Association
Budget shall include no funding for the purpose of installing lights at
Browns Chapel Park Ballfields #2 and #3.
• In 2001, when RA applied to the DRB to light BC2 there were 55
registered affected parties.
• That application was for 6, 85-foot high poles on a
90-foot diamond ball field, with much less tree buffering and a
light shut-off time of 10:30 pm
• The current application has 6 registered affected parties, 4 from
Waterfront Road. We have worked directly with the cluster President
on schedule and timing concerns for a 9:00 pm shut-off time
DISTANCES TO STRUCTURES
PARKING LOT LIGHTS AND
CONCESSION STAND LIGHTS
• Initial proposal for 10, 20-foot high poles with LED
shoebox fixtures, and two down-light wall pack
fixtures on concession stand
• Requesting deferral of parking lot lighting and
concession stand lighting for further study
