Carrie and Glenn – <br />In review of the submittal documents for the Bethel University scoreboard, I have a few follow-up <br />items that I’m hoping you can assist with: <br />From the initial discussions, the City requested that the submission include decibel levels at the <br />property line of current scoreboard and then what they will be with new scoreboard. Has this <br />been verified? Please provide that data. New Scoreboard Engineer Response (NEVCO): “The <br />area indicated on the drawing is behind the direction that the scoreboard will be facing. <br />Stadium Pro sound systems are commonly installed in residential areas, so the design includes <br />an enclosure that completely surrounds the speakers with a 1” thick acoustic foam. The <br />purpose of this foam is to reduce sound wave vibrations to the mechanical structure of the <br />scoreboard display products, but also to dampen the sound waves leaving the rear of the <br />display (where we don’t want them). It’s difficult to predict the exact decibel level that will <br />penetrate the driver enclosure, the SP-1000 enclosure, and the acoustic foam, but it will be <br />primarily isolated to lower frequency levels coming from the subwoofer. My best estimate <br />would be 70 - 80 db at most.” <br />Bethel Response regarding Existing Scoreboard: “Decibel readings we took today –on the <br />current PA system – max out at upper 70's at the property line, and then as you get closer to <br />the audio source (press box) it climbs into the mid- to upper-80's. I didn't see 90's until I was <br />standing on the bleachers almost right in front of the speakers / press box, and levels never <br />reached 100dB. Again, I'm confident the new system (which will be aimed northeast from the <br />scoreboard towards the home bleachers) will have less of an impact on the residents than our <br />current system (which is aimed right at the Arden Oaks residents).” <br />·There was mentioned of a revised rendering more reflective of site foliage since the tree <br />coverage is not as thick as shown in the illustration. With the rendering as submitted, please <br />provide a few pictures that will illustrates view from adjacent parcels to scoreboard and <br />scoreboard looking towards adjacent parcels. Bolton & Menk Response: We have provided an <br />illustrative graphic (Scoreboard Views) showing views from Bethel into the neighboring <br />properties. Based on the location of the scoreboard, it appears there is adequate existing tree <br />cover to screen the scoreboard from the neighbor’s view. Ultimately, Bethel wants to be good <br />neighbors and are willing to work with the city / neighbors. <br />·Will there be new light poles with sound attached? If so, please provide manufacturer <br />information for light poles and update site plan to show location of light poles with speakers. I <br />had written in my discussion notes that there was consideration of having four (4) directed <br />towards home grandstand and two (2) on the visitor side. Bolton & Menk Response: No <br />speakers are part of the new light poles. <br />·The speaker dispersion sheet shows the scoreboard located in the center of the field, do you <br />have an updated dispersal plan with scoreboard location shifted to the SW corner as proposed? <br />Bolton & Menk Response: The scoreboard is in a similar position to the sound dispersal <br />graphic NEVCO has provided. NEVCO is not able to provide an updated graphic as this is a <br />stock graphic, however the design team is confident the provided heat map graphic conveys <br />the sound dispersal in a way that representative of the similar proposed scoreboard location.
