Item 7Gk. City of Southlake Department of Planning 1400 Main Street, Suite 310, Southlake, TX 76092 MEMORANDUM September 28, 2005 TO FROM SUBJECT The Honorable Mayor and City Council Ken Baker, AICP, Planning Director Variance to Chapter 11, Article III of the Southlake City Code (Noise Nuisances) for the Shops at Southlake (Central Market). REQUESTED ACTION: Consider the requested variance to the Noise Code. BACKGROUND: The Southlake City Code, Chapter 11, Article III (Noise Nuisances) regulates noise levels in the city. The standards established are as follows: The image below shows typical examples for different decibel levels of sound: Sotiod Pressiltg Level, d8 Pfl8LIInatic ChIpper (at 511) 110 Property receiving sound Daytime Nighttime Sundays Nmpaper Press Power Lawn mower Residential 60 dBA 55 dBA 55 dBA 0.2 so Commercial 70 dBA 65 dBA 65 dBA 0 The image below shows typical examples for different decibel levels of sound: Sotiod Pressiltg Level, d8 Pfl8LIInatic ChIpper (at 511) 110 Teslile L&Gm Book- n -Ro111 Band 5 100 Nmpaper Press Power Lawn mower 1 90 o lesel TWO 40 mph (al 6+0 fl) milling Maakine at4 fi 0.2 so rassenuer Car 60 mph (at 50 fl) TO Coiyom n (a13 R) 60 0 50 OuWA Room 40 0.01 30 0.005 20 0.002 10 0,001 0 Gt ®d Presst're, Pa 14 Book- n -Ro111 Band 5 2 Power Lawn mower 1 Iar opewot's earl 01 milling Maakine at4 fi 0.2 Garbage Disposal Iar 3 tj I 0.1 V000m 0030er 0,05 0 Air Ci3mditiciiing lWindow Unit at 25 ft) 0.01 0.005 0.002 0,001 U005 0,0002 0.0001 0,00005 0.00002 1 Shops at Southlake, located at the southeast corner of F.M. 1709 and S. Carroll Avenue, may require a variance from the above standard. At present, a 14' high wall is proposed along the southern property line to buffer the adjoining residences from noise nuisances expected to be generated by the proposed adjacent commercial operations. This wall would meet the city's standards of limiting noise at the residential properties to under 55 decibels. However, due to the scale and aesthetic concerns of a 14' high wall, City Council and adjoining property owners may opt for a lower wall. In that case, a variance to the noise standards will be required for the development. Attached with this memo is an exhibit depicting the area affected by this variance request. Also attached are letters from the developer's acoustical consultant with information pertaining to noise analysis at the southern edge of the subject property.

JEA estimated delivery truck and refrigeration equipment noise levels received on residential properties located south of the development site, based on various conceptual barrier heights, in accordance with barrier location, configuration, and construction concepts outlined in our Sept. 12 report to Cencor. Estimated noise levels received on south neighboring residential properties follow, using two primary facility noise sources: 1) a single passing tractor- trailer with high diesel exhaust stack (exhaust at about 12' above pavement), and 2) continuous operation of outdoor refrigeration condenser equipment associated with the proposed HEB building. As shown in the table above, the Southlake Noise Ordinance allowable nighttime or Sunday noise limit of 55 dBA can be achieved using a 14' -tall noise barrier, and may be achieved with barrier height of 12' or more, but cannot be achieved with a barrier shorter than 12', even with implementation of optional barrier absorptive or diffusive surface treatments discussed in the Sept. 12 report.

Palmer Cencor Realty Services 3102 Maple Avenue, Ste 500 Dallas, TX 75206 RE: Site Plan Environmental Noise Review Shops of Southlake and HEB Central Market, Southlake, Texas Dear Sirs: JEAcousTics (JEA) was retained on behalf of H.E. Butt Grocery Co. (HEB) by Selser Schaefer Architects (SSA) and by Cencor Realty Services to provide acoustical consultation for environmental noise issues related to the proposed development for the Shops of Southlake, including an HEB Central Market in Southlake, Texas. Our scope of services includes review of the site plan, review of the Southlake development code regarding noise, identification of potential noise sources and evaluation of noise propagation to adjacent or nearby residential receiver properties. JEA has conducted a review of the site plan for the purposes described above. Recommendations for environmental noise control, including design parameters and guide specifications for noise containment, isolation or attenuation concepts are provided below for your consideration. Site Conditions The development site is located at the southeast intersection of East Southlake Blvd. and South Carroll Avenue. The lot is currently undeveloped. To the north of the proposed development, is a commercial /mixed use Southlake Town Square, which includes eateries and a bank (NW corner). Across South Carroll Avenue, east of the center that will contain the Central Market, is undeveloped as well. South of the proposed development is a residential community. Properties with O USTI CS HEB C-entr it Market, Soutlilake, Texas r Environmental Noise Review Engineered Vibration Acoustic & Noise Solutions Page 2 residential dwellings, typically 2 stories, back up next to the service areas of the Central Market and southern shops of the Southlake development. The Central Market store building will generally occupy the south portion of the development site. The project site (plan shown below) will contain the new store building with surrounding paved parking for customers to the north, and driveway areas to the south for HEB fleet and vendor (i.e., tractor - trailer and delivery van) operations for Central Market and adjacent retail to the east and west. Grade elevation at the residential properties is approximately equal to (up to 2' higher than) the elevation of pavement at the proposed facility. As the grade elevation increases going east along the proposed site the elevation of the grade at the residences increases likewise. J p 'O W A �-I 0 U x H 0 C e l C Southlake Central Market Site Plan Showing Adjacent Land Uses On the morning of August 6, 2005, JEA visited the project site. The objectives of the site visit were to measure ambient noise levels on neighboring residential south of the project site and to observe and document primary noise propagation paths and sensitive noise receivers surrounding the site. Southlake Blvd. is a 4 -lane roadway (2 lanes in each direction with a center turning lane). South Carroll Avenue is a 2 -lane roadway (1 lane in each direction). Based on observations at the site, it appears that vehicular traffic noise from both South Carroll and Southlake Blvd. are not major contributors to the background noise (due to distance for Southlake Blvd. and traffic for South Carroll Ave). 1705 West Koenig Lane JACK EVANS & Assoc., INC.

Overall, we anticipate moderate to low ambient noise levels (around 45 dBA) in the general vicinity of houses south of the development site. Southlake Noise Ordinance The Southlake Noise Ordinance' defines objective noise levels that are declared to be unlawful. (See attached Ordinance in the Appendix.) The following table summarizes noise levels that are unlawful when received on a residential zoned property: Limits for Noise Received on Residential Zoned Property Property Receiving Sound Daytime Nighttime Sundays Residential 60 dBA 55 dBA 55 dBA Commercial 70 dBA 65 dBA 65 dBA The noise ordinance specifically states, "measurements are intended to be taken on typical single incident noise from activity at the noise source." JEA interprets this statement as an instantaneous measurement for a single event. Therefore, the design goal will be relative to the more stringent nighttime criteria. The noise ordinance specifically restricts (Sec. 11- 61 -(11)) "Conducting any commercial or industrial trash or waste pickup within 1,000 linear feet of any residential dwelling during the nighttime. Potential Facility Environmental Noise Sources Reviews of the site plan and JEA's experience with HEB supermarkets and other retail facilities indicate the following potential continuous, intermittent and transient noise sources at the proposed facility: • Truck docks: ground level, combination of continuous (idling) and transient ❑ Vehicle noise, arriving, idling, and departing ❑ Vehicle refrigeration equipment associated with refrigerated trailers ❑ Loading and unloading operations (palettes, impacts, forklifts, carts) • Vendor delivery vans: ground level, transient, limited duration • Grocery refrigeration chiller equipment: ground level or roof mounted, relatively continuous Cite of Southlake, Code of Ordinances, Ordinance No. 778 1705 West Koenig Lane JACK EVANS & Assoc., INC.

Equipment locations may affect propagation paths and net attenuation due to distance losses and reflections. Specific noise mitigation measures will be refined to achieve permissible noise levels at property lines. Potential Facility Noise Received at Existing Residential Properties Following the site visit, JEA conducted analyses to evaluate potential facility environmental noise received at neighboring properties. The objectives of the analyses were: • To estimate noise levels produced by fleet and vendor activity in the loading docks and driveway south of the site • To estimate noise levels produced by proposed condensers and generators at the new facility, based on equipment manufacturer's noise data; • To project noise levels received at neighboring residential properties; and • To compare the projected noise levels to the Southlake Noise Ordinance Operations noise from vendor delivery trucks and tractor - trailers in the receiving docks may be occurring during early- morning hours from 6 am and on Sundays. Therefore, the controlling objective limit in the ordinance would be 55 dBA at the property line for operations noise and 55 dBA for air conditioning and refrigeration equipment.

Thus, the objective limit for generator noise would be 60 dBA at the property line. Truck Docks artd Trucks Without providing effective noise barriers to block the direct path of sound from tractor - trailer traffic and vendor van loading and unloading activity on the development site to existing neighboring residences, some noises produced by the proposed development are likely to exceed nighttime noise levels allowed by the noise ordinance. If no effective noise barrier is in place, noise levels associated with some of the louder vendor traffic and loading dock operations received at the existing residential properties to the south can be expected to be as high as 69 dBA. These noise levels will be associated with transient events, such as backup beepers, moments of tractor acceleration, truck horns, vendor van rollup- doors. For longer - term events, such as idling of tractors, trailer refrigerators, and longer periods of relatively continuous loading dock activity, noise levels received on north and east neighboring properties can be expected to be less than 69 dBA but which still exceed the 55 dBA limits for nighttime noise. With effective noise barriers in place, discussed below, noise levels can be reduced to meet ordinance limits. Buildin,a Systems (HVAQ Building HVAC design has not been completed and specific equipment has not been selected. JEA obtained likely condenser information and modeled predicted noise at the southerly residential property boundary to be below 72 dBA. Refrigeration equipment noise is expected to have tonal character, which may also increase neighbor's annoyance. Installation of noise barriers and/or acoustical absorption around refrigeration equipment would reduce equipment noise and its impact at property boundaries. Diesel Generator Continuous noise produced by the generator during routine maintenance operation or exercise, can be expected to be 66 dBA (without noise barriers) at the residential properties south of the development. Maintenance operations are expected to be during the daytime. With a 60 dBA daytime noise ordinance and 6 dB of noise reduction required, noise mitigation for tractor trailer activity may be used to meet the criteria. Traffic: On- premises partner and customer traffic noise in parking areas and driveways on the development are expected to comply with noise ordinance requirements without additional noise mitigation. However, some partner vehicles may be louder than expected, and use of a noise barrier to address vehicle noise along primary driveways may be warranted, especially where noise barriers installed to address vendor tractor - trailer noise concerns can be utilized to also address partner /employee traffic noise. Trash Compactors Trash compactor operation is expected to comply with daytime noise ordinance requirements without additional noise mitigation. However, 1705 West hoeni Lane Eti DNS & Assoc., INC.

Pavement Sweeping Parking lot sweeper operations are not anticipated during nighttime hours for south driveway areas. Parking lot sweeper noise is expected to comply with noise ordinance requirements without additional noise mitigation. Planning and Design for Noise Mitigation According to current plans, fences or walls that may act as effective noise barriers are planned along the southern property between the Central Market and the residential neighborhood. These walls should be designed and utilized to be effective noise barriers that obstruct the direct path of primary noises (tractor exhaust stacks, loading docks, truck driveways, vendor parking areas, and refrigeration condensers) towards residential properties to the north and east. 1. Tractor - Trailer Delivery Daytime /Non - Sunday Scheduling JEA understands that HEB has agreed to limit tractor - trailer deliveries to daytime hours between 6 am and 10 pm. The Southlake Ordinance defines daytime hours to be 7 am -10 pm, when (except on Sundays) the noise limit is 60 dBA rather than 55 dBA for nighttime. Thus, even with deliveries restricted to 6 am -10 pm, some deliveries may occur during nighttime hours or Sundays; subject to the 55 dBA noise limit. If deliveries can be limited to Ordinance daytime hours (i.e., 7 am- 10 —pm), Monday through Saturday (i.e., not on Sunday), the 60 dBA noise limit may be observed, and the 14' height of some of the western portion of the South Pr °oporty Line Bari °ier described below in item (2.a), west of the HEB building, may be reduced to 12'. 2. Truck Noise Barriers In order to reduce idling and driving noise from tractors, trailer refrigerator noise, warning beeper noise, compactor pickup noise, and other vendor loading dock facility noise received at south neighboring properties, implement the following items: a. South Property Line Barrier ❑ West Portion: Install a noise barrier at least 14' high, as measured from driveway pavement elevation along the west portion of the southern property boundary, where tractor - trailer traffic is anticipated. The barrier should extend from near South Carroll Avenue to about the plane of east face of the east -most condensing unit, about 150' east of the truck docka total length of about 750' from S. Carroll Ave. 1705 West Koenig Lane JACK EVANS & Assoc., INC.

Thus, over a distance of about 100' from west to east the middle portion of the barrier could step down from 14' to 8' height. ❑ East Portion: For the east portion of the south property line, the barrier height may be 8' tall, extending to the east end of the development property. The east portion of the barrier may follow the driveway curving north, or it may remain parallel to the property boundary. �•��� 72,413 S.F. ------ COMPACTOR OMPRE55QR CENTRAL M A R K E T C FF= 633.50 nI COMPRESSOR N� l - — - - - -- -� LOADING � L1 A X Q[] ABSORPTIVE NOISE BARRIER: V ABOVE TOP OF — COMPRESSOR (SEE INSET) LOT 6 BARRIER HEIGHT 14 ' 1 13'1 12PI 1 I'l 10' 9' 1 8' 759 FROM SOUTH CARROL ENTRANCE TiLLEAs END OF SOUTH �ermonen ae: - PROPERTY BOUND Site Plan Showing Noise Sources and Recommended Noise Barriers b. Noise Barrier Construction: Noise barriers should be constructed of materials weighing at least 2.5 pounds per square foot ( >_ 5 psf preferred) and should be solid, not having open weep holes, seams, or other perforations that would allow the passage of air and sound through the wall. Where gaps (up to —4" above grade) are required at the base of the barrier for stormwater drainage, etc., ensure that the direct path of sound (direct line of sight) from the drainage gap to a tractor - trailer exhaust stack (12' above pavement at loading dock or rear driveways) through any portion of the gap is obstructed by a secondary barrier or earth berm. Masonry or concrete is preferred for barriers, including precast concrete panel systems (e.g., Superior Concrete Fence). Wood, sheet metal, or other materials may also be acceptable. For a wood barrier (as a less effective alternative), use battens to seal gaps between boards, and implement a maintenance plan to repair and replace battens that crack or warp over time. 1705 West Koenig Lane JACK EVANS & Assoc., INC.

Landscaping (Acoustical Effects of Trees and Shrubs) Approximately 1 dBA of environmental noise reduction can be achieved by proving about 100' of dense, evergreen treeibrush growth to separate outdoor noise sources from sensitive receivers. Compared to the acoustical effectiveness of 8'- to 14' -tall noise barriers recommended and potential effects due to meteorological conditions (wind, temperature - gradient refraction), noise reduction provided by proposed, heavy landscaping on Lot 6 would be insignificant. 4. Optional Acoustically Absorptive or Diffusive Surfaces Tractor and vendor van traffic noise will build up between the south building face and the noise barrier. Acoustical absorption or diffusion to reduce noise build -up is not required, but may be considered for implementation to achieve up to 2 dBA noise reduction if noise barriers shorter than those recommended item (2.a) are desired. To augment barrier performance so that 14' barriers can be reduced to 12' minimum, apply acoustically absorptive or diffusive surfaces to either the building face or face of the noise barriers to reduce the build -up of noise. Adding optional absorption or diffusion will not allow the recommended 14' barrier height to be reduced lower than 12' above driveway elevation: a. Optional absorption: Consider adding apsorption to about 50% of north - facing barrier surfaces (or possibly the opposing south - facing building surfaces). Absorptive finishes should have a Noise Reduction Coefficient (NRC) no less than NRC 0.50, and may include Pyrok Acoustement`"' spray - on cement based acoustical plaster, SoundBlox'R acoustically absorptive CMU, medium density (3 -7 pcf) fiberglass panels faced with perforated metal panels, or other acoustical materials suitable for use outdoors. See the attached product and vendor list. Absorptive materials with higher NRC ratings may be used to cover less surface area. Acoustical absorption is a function of absorption coefficient (NRC value) and surface area. Thus, the acoustical absorption provided by 1500 square feet of material with NRC 0.50 is equal to that provided by 750 square feet with NRC 1.0. b. Optional diffusion: In addition to, or as a less effective alternative to adding acoustically absorptive surfaces described above, consider implementing one or both of the following to help reduce the build -up of sound in truck docks or vendor driveways: i. Splay or slant the noise barrier (in plan) such that the building face and noise barrier are not parallel. Splays or slants should be at least 3 degrees from parallel, 6 to 7 degrees preferred. ii. Apply acoustically diffusive surface textures with depth of articulation > 2" to the noise barrier and/or building face. 1705 West hoeni�1 Lane Eti DNS & Assoc., INC.

If implemented as options to reduce noise barrier heights in item (2.a), the type and placement of absorption or diffusion should be reviewed by JEA to ensure its effectiveness before designs are finalized. 5. Refrigeration Equipment Noise Barriers Based on estimated equipment noise, additional attenuation is required for the southeast condenser equipment. Install an acoustically absorptive noise barrier 1' higher than the top of condensing units along the east, south, and west face of condensers. The barrier should have acoustical absorption with NRC >_ 0.70 covering at least 70% of the barrier surface(s) facing the equipment. Barrier construction should be as in item (2.b) and absorptive materials should be similar to those described in items (4.a); with NRC >_ 0.70. As an alternative, install a non - absorptive barrier T higher than top of units.
