BROWN’S CHAPEL #1BALL FIELD AND PARKING LOT

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 FROMAPRIL 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 ANDCONCESSION 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
