Multi-Use Entertainment Venue

Noise/Sound Study and Lighting Discussion Points/Concerns Timing of the Release of the Studies Design incorporated most modern state of the art technology designed to direct sound within the Venue. The studies was performed following completion of the design for an aggressive design/build project schedule. The studies were performed based on the state of the art technology recognizing the urban setting that exists. Current noise/sound study only covers impact of Activities Most other activities outside of baseball will not utilize the sound system of the Venue. Events such as fireworks and concerts require a separate permit.

Option is already being pursued to perform a separate study regarding the Impact of Concerts and Fireworks – challenges include unknowns regarding concert setups that vary based on the show/act, and the design of the Fireworks show, which is not complete Projection of 300 events being held at the Venue is alarming when noise/sound There will be 70 home games (35 fireworks displays), study only accounts for 70 ballgames approximately 3 to 4 concerts the first year. Other events will be smaller in-door events or community oriented or activities that will have significantly less impact than baseball, concerts or fireworks. Multi-Use Entertainment Venue

Other Discussion Points/Concerns Traffic Study The study is being finalized for submittal to SCDOT. Upon approval, it will be released and community meetings will be scheduled. The traffic study is being performed by a consultant and pertains to the entire development and not the Venue in isolation. Parking Plan The parking plan for the first year of the Venue is being developed and will be released once complete.

Concern Regarding Attendees Parking within Surrounding Neighborhoods This concern is being taken into account in the development of the parking plan. Columbia Commons Baseball Stadium

Environmental Noise Study

Wrightson | Johnson | Haddon | Williams Sound System Environmental Impact Overview • Predict loudspeaker sound levels at the surrounding community from the new baseball stadium • Provide comparison to the City of Columbia, South Carolina Noise Ordinance

Wrightson | Johnson | Haddon | Williams Firm Overview: WJHW

• 20+ years experience in offering state-of-the- art design services and consulting in audio, visual, video & scoring displays, acoustics, and other technology services • Sound System Design: Ballpark, Renovations, Durham Bulls Athletic Park, Nashville Sounds Ballpark, Autozone Park in Memphis, among many

Wrightson | Johnson | Haddon | Williams Acoustics Terminology

• Sound Power Level – total sound energy created by a sound source; measured in decibels (dB) • Sound Pressure Level – rapid pressure fluctuations which the ear interprets as sound; measured in decibels (dB) • Decibel (dB) – measure of sound pressure or sound power levels; calculated as a logarithmic ratio to a base sound pressure/power (often, the threshold of hearing) • dBA – A-weighted sound pressure level; closely related to the human hearing sensitivity to various sound frequencies

• dBA – A-weighted sound pressure level; closely related to the human hearing sensitivity to various sound frequencies

• Leq – Equivalent Continuous Sound Level – single sound level value equivalent to the same energy as fluctuating sound levels over a period of time, can be considered a type of “average” sound level. Output of the environmental noise model.

Wrightson | Johnson | Haddon | Williams Environmental Noise Model Sound System Design • Distributed speaker system consisting of 10 speakers in outfield, additional speakers mounted under the canopy. • Outfield speakers on poles approximately 50 ft high • Speakers selected and aimed to just cover seating • Allows system to be operated at lower level with higher quality • Sound system noise levels modeled 83-85 dBA in seating

Wrightson | Johnson | Haddon | Williams Environmental Noise Model

SoundPlan Modeling Software Inputs: • Noise levels in the stadium of 83-85 dBA. It should be noted these levels will be intermittent, typically lasting in intervals of no more than 30 seconds at a time during the game. • Stadium, First Base Building, Babcock, and Ensor Buildings geometry as provided by • Terrain from the site topographical data • Foliage, winds, other future buildings not included in model to provide conservative estimate • Crowd noise not included in the model; not controlled by facility and consists of many individual sources so sound travels less far

Wrightson | Johnson | Haddon | Williams Discussion

• Noise levels from the sound systems for baseball use meet the applicable City of Columbia Noise Ordinance outside of the Planned Use Development • As discussed previously, noise levels are for typical minor league baseball games, and are typically intermittent • Typical ambient noise levels for an urban neighborhood are approximately 55 dBA – While the loudspeaker system could still be audible and noticeable because of the speech and musical content, typical stadium operations would not be louder than those ambient levels in an urban residential area
