DRAFT -13- 643 644 Larry Wright: Over the last 10 years, has the development of any enterprise in Orange County 645 depreciated surrounding property values. 646 647 Mike Wheeler: I didn't find any data to support that. 648 649 Larry Wright: In your experience, have you ever shown that or seen that? 650 651 Mike Wheeler: Ever? 652 653 Larry Wright: In the last 10 years. 654 655 Mike Wheeler: No. 656 657 Noral Stewart: I am with Stewart Acoustical Consultants, 7330 Chapel Hill Road, Raleigh, N.C. 658 1 have been sworn. I am a professional acoustical consultant. I have been in this business for 659 over 30 years. I obtained my training at North Carolina State University in the Department of 660 Mechanical Engineering through PhD. I am a Fellow of the Acoustical Society of America, a 661 Fellow of ASDM International, a member of the Institute of Control Engineering and a past 662 president of the National Council of Acoustical Consultants. I was asked by Mr. Purner to 663 review his plans and visit his site with respect to any potential problems from the sound of dogs 664 affecting the neighboring areas and assure they would be able to comply with the county noise 665 ordinance. I did calculations and reviewed the site plan, the concept of the building, did some 666 calculations, visited the site, discussed it with Mr. Purner in length, listened to the sound in the 667 vicinity, observed this is an area in some ways not particularly noise and in other ways it does 668 have some noise sources around; the railroad, the interstate highway, the city facilities, a 669 shooting range not too far away and the potential of the park being developed with recreational 670 activities and I did observe there were already some barking dogs in the community. I did an 671 analysis of the dog sounds outdoors with the plan as it is shown and found they should easily be 672 able to comply with the daytime limits in the County Noise Ordinance. I have reviewed the 673 building plans as they are. The concept is the dogs will be indoors during the nighttime hours 674 and only outdoors during the daytime hours. They do not have the building plans complete... all 675 the little details have not been worked out yet. The concept and plan is that I would continue to 676 work with the architect on the development of those details to ensure there are no fatal flaws in 677 the design. I am confident the building can contain the sound to where they would meet the 678 nighttime limits to the closest boundary which would be the one to the south, the County park, 679 assuming the residential limits would apply at that boundary which are the most stringent limits 680 so we would have to work with the architect to make sure there are no fatal flaws in the detail of 681 the plans as they are worked out and submitted for a building permit but it can certainly be 682 done. I have done this with others who have been through this in the 'last couple of years so we 683 know we can do that. 684 685 Bob Hornik: Mr. Stewart, are there any particular features either of the plan or the site itself that 686 helped you form your analysis? 687 688 Noral Stewart: Yes. The layout of the building and the site is very good. The building is 689 situated such that the outdoor areas for the dogs are to the north side. There are some runs on 690 the exterior of the building on the north side. The shape of the building and its location does an 691 excellent job of blocking that sound going to the south where the parkland would be. To the 692 east where there are neighbors you have from the building itself would be 400 feet but from the 693 area where these dogs would be outside it is more like 500 feet. And that distance alone is 694 extremely helpful in reducing the noise reaching that area. The general layout with the buffer 695 space to the nearest non -owned boundaries and the owners having large parcels of land which 696 create buffers to the north and west are extremely helpful. I consulted the Noise Ordinances OC Board of Adjustment — 5/14/2012 Page 13 of 41
