Van Houten & Associates, Inc. for technical expertise and backup, relating to JNA, for the September 21, 1987 City Counct 1 meeting. BACKGROUND At the regular Ctty Council meeting on August 3, 1987, the Counctl took the following actions regarding the airport noise issues: 1. Oirected staff to request a formal proposal from the airport. 01rected staff to soltctt no/se consultant proposals to monitor the proposed additional noise monitoring program, placement of equipment recommended by the Airport Including evaluating the appropriate statistical data provided by the Atrport and interpreting any results. OXSCUSSION/ANALYSZS J~/A PROPOSAL The proposal to provide additional temporary noise monitoring equipment in the Tusttn area is scheduled to go before the Airport Commission on September 16, 1987. At the writing of this report, a draft copy of the airport administrative report to the Conetsslon ls enrouta to the City for our comments prior to preparation of the final report. Airport ~4anager George Rebella has indicated that the report proposes the purchase of additional noise monitoring equipment, as well as hiring additional personnel to attend the stations. Data tabulations and Interpretation would be performed by existing, experienced person, nel at the noise monitoring center. The proposal wtll go to the Board of Supervisors for final approval approximately ten (10) days following the action of the Airport Commtston. Following the Board of Supervisors approval, the Airport Administration can begin implementation. Whtle the necessary equipment for the monitoring stations has been reserved at the manufacturers, the hiring process for City Council Report ~irport Noise September 8, lg87 Page additional personnel (engineering technicians wtth acoustical background) is expected to take a couple of months. The Clty could expect full Implementation by December. NOISE CONSULTANT Staff Interviewed three noise consu]tants, all certified by the County of Orange to perform acoustical work tn the County. The three consultants interviewed Included: 3. 3. Van Houten & Associates, Inc.; Davy & Associates, Inc.; and Acoustical Impacts International. None of the three consultants are presently under contract to iNA, nor have they ever been, The interview process provided staff with background on the individual consultants knowledge, experience and interest in performing the following scope of work for the City: · 1. Revte~ of Standards, Regulations and Poltctes- review of extsttng Federal, State and County policies, regulations and ordinances as they relate to operations of 3WA and thetr tmpacts on the City, particularly, stngle event notse exposure level (SENEL) criteria. £xamtne extsttng and recommend new mitigation measures to reduce impacts withtn the Ctty. 2. Evaluate the Airport's Temporary Monitoring Proposal - evaluate the temporary noise monitoring program proposed by 3WA, verifying the appropriateness of monitoring locations and recommending alternative locations tf necessary. Identify ~he minimum amount of data necessary to provide a statistically significant findtng. 3. Perform Limited Noise Monitoring - perform single event aircraft noise measurements at a representative number of locations, during identical time periods as JWA, to verify precision of JWA measurements {and consultants) and by examining instrument calibration, maintenance and field procedures. 4. Re-evaluate CNEL contour locations - re-evaluate the location of the 60 and 65 dB CN£L contours for JWA as they affect the City. This would be performed by use of data collected by JWA and through Item No. 3 above and also using operational data consistent with the various commitments of JWA to the commercial operators. $. Interior Noise Exposure £valuatton - obtain a representative number single event noise exposures at interior and exterior locations of homes impacted by aircraft noise. Determine the noise reduction qualities of typical residential construction and compare the interior noise levels with other impacted areas of the County. Identify modifications to reduce impacts where appropriate. Corn rnunity Development Deparzment City COuncil Report Airport Noise September 8, 1987 Page three 6' Revtew of Ftndlngs and Recommended Action(s) - prepare a brief review of the ftndtngs and provide a recommended course of actton, upon completion of the above tasks. 7. Attendance of Staff and Pub.lic .Meetings - attend staff and public meetings as necessary to present flndtngs and support actions'to be taken by the City. Task numbers 4 and 5 above are not essential to provide the tnformatl'on and support as directed by the Counctl at the August 3rd meettng. However, they were optional tasks that were explored with each consultant in the event that the Ct ty Counctl wished to consider a greater depth and detail of information. Based upon Interviews conducted with each consultant and proposals submitted, staff has concluded that 3. 3. Van Houten & Associates, Inc., have demonstrated the greatest level of knowledge, detatl and expertise sutted to serve the City's · needs regarding the airport noise issue. A time schedule along with items to be delivered has been excerpted from their proposal (a copy of which ts attached in full) and Is provided immediately'below: 1. Letter report of findings regarding standards, regulations and poltctes wtll be submitted within two weeks after authorization to proceed. 2. Letter report of evaluation, with recommendations, reagarding the airport's noise monitoring Proposal will be submitted within five (5) working days from receipt of the document. 3. Noise measurement report and evaluation of precision will be submitted within five (5) working days after completion of the field work. 4. Letter report and CNEL Map indicating the location of the contours as they impact the City of Tustin, will be submitted within 14 working days after completion of the field work of Task 3. 5. Letter report of findings of the interior noise measurements and exposures w111 be submitted within 14 working days from completion of the field work of Task 3. Corn rnunity Development Department ctty Counctl Report ~trport Noise ,eptember 8, 1987 Page four 6.~- Letter report, with recommendations, will be submitted to the City within 20 working days of the con~letion of Task 3. 7. Project principal, John H. Van Houten, will attend staff and public hearings as needed to support the proposed effort. Total time is approximately 2.5 months. Item No. I could proceed prior to the beginning of JWA's program. Total fee estimates (broken down into not-to-be-exceeded amounts in the attached proposal) come to $15,470.00 fqr all of the first six tasks discussed earlier. Attendance at meetings by the Project Principal (John J. Van Houten), would not exceed $270.00 per meeting {assumed 3 hours/meeting). Elimination of one or both of the optional tasks of evaluating CNEL contours or obtaining interior noise levels, would reduce-the total amount of the contract by $2,740, and $1,240 respectively. CONCLUSION Staff believes that the prOposal by J. J. Van Houten & Associates, Inc. fully addresses the issues and concerns identified by the Council at the August 3rd meeting, both in subject matter and time schedule. If the City Council concurs, ~taff recommends that direction be given to prepare a contract for services to de placed on the City Council September 21, 1987 agenda. If the Airport's proposal should be turned down by the Board of Supervisors, staff would still recommend entering into a contract with J. J. Van Houten, Associates, Inc., as such data they :could produce would be the only data available beyond what the Airport has from its existing monitoring system for the City to consider in regards to any future actions it may wish to take.

Hay Tustln, CA 92680 Dear Steve, ~ Pursuant to our telephone conversation of August 25, 1987, I am enclosing a copy oi~ the draft proposal for the noise measurement program for Tustin. I will send you a copy of our staff report to the Airport Commission as soon as it is prepared. Thank you for your assistance. Sincerely, : George A. Rebella Airport Manager GAR:ln 0244A Attachment Date: August 18, 1987 To: George A. Rebella, Airp6rt Manager From: Karen L. Robertson, Airport Access/Noise Officer Subject: Noise Measurement Program for Tustin Per your request, I have prepared an outline describing the measurement program anticipated for the Tustin area. Please indicate any changes or suggestions you may have so that I may adjust my program accordingly. TUSTIN MEASUREMENT PROGRAM PURPOSE: To establish baseline noise levels in the Tustin area, deteA-~,,ine extent of noise impact, and to make recommendations as appropriate. PROCESS I. Obtain addresses of interested parties for testing : II. Plot potential testing locations on base map as provided by City of Tustin; detea~,,ine if proposed testing locations adequately encompass the City; dete~%,ine additional testing sites as necessary. III. Schedule testing. Propose to test each location for a minimum of one week, with possible exceptions as needed (such as weather delays, etc.). The testinE will begin at approximately 0650 and will ~un continuously until approximately 2315. We will need to hire several shifts of temporary personnel to man the equipment, provide breaks and meal breaks. The noise monitoring equipment will comprise of a microphone elevated approximately 20 feet above ground level, connecting cable, and the monitor itself. The person with the monitor will identify the type of aircraft, caa-~-ier identification (where possible) and time of day, coma-elated with our NOVA time. TUSTIN NOISE MEASUREMENT PAGE 2 OF 5 IV. Interpretation of data. Ail data will be reviewed and interpreted by noise abatement staff only; temporary help will not be involved in data manipulations. Use of the DA607 will give maximum noise levels, time of duration, and SEL values for each aircraft event exceeding the threshold. Given what I have seen in the field so far, it is very likely that some aircraft events will not register on the~ noise monitor. This data will be noted. Staff will dete~,,ine average daily and weekly SEL values. When the B&K equipment is purchased, the data obtained will give both aircraft and community noise levels; staff will average daily and weekly SEL, Lmax, LEQ and appropriate L values for each test site. The data will compare background noise levels with aircraft events, as well as give a time vs noise level strip chart of each. Staff will also examine the noise leve~s of each day of the week to dete~-~Line if there is any pattern of noise which we are unaware. V~ Additional testing as necessary may be provided for support data; this process will remain unknown until the data is evaluated. V~. As both B~K monitors become available (purchased), staff will dete~-~,ine a minimum of three sites for further testing. Such testing will include simultaneous noise monitoring inside and outside the home/office; windows will be closed for two days; then windows will be opened for two days to detez-~,,ine noise reduction of the structure. Data will be analyzed and interpreted by staff; manning of noise 'monitoring equipment will be by temporary personnel. VII. Staff will prepare final report with all findings and recommendations. TUSTIN NOISE MEASUREMENT PAGE 3 OF 5 Items that require dete~-.,ination and/or clarification are as follows: 1. Hiring of additional people, either via extra-help limited term, or temporary help from an agency~ '~ 2. Method and date to purchase new noise monitors. This is necessary if you want to do any simultaneous testing~ At least one monitor is required to be available at all times for no~al noise abatement uses; you may wish to 'consider purchasing three new monitors instead of two if you want the noise testing to begin earlier than scheduled. 3. I anticpate the start date of testing to begin within three weeks after determination of a new M7 monitoring ~ite: the DA607 equipment will be in use until that time. Hopefully, it will be availble for use in Tustin by late-September. ~. Giving one weeks time .for each test site, 5 weeks to interpret preliminary data, one weeks time for each simultaneous noise test, total time will be approximately 24 to 26 weeks. This value assumes good weather conditions (no rain or wind), no equipment failures and full accessability to each test site. This time schedule will be altered if the noise monitor is needed for regular use by Noise Abatement staff, unless the new monitors are purchased by late-September. PROPOSED BUDGET I. Extra-Helm .Extra-help (or temporary) positions at an Engineering Aide I level range from $7.~5 (step 1) to $9.85 (step 12) per person per hour. Extending these values out for 2~ weeks with 3 staff positions, the salary cost ranges from $21,~65.00 (step 1) to $28,368.00 (step 12). Note these figures~ are for salary only. TUSTIN NOISE MEASUREMENT PAGE 4 OF 5 II. E~uimment Quotes for the type of equipment necessary to provide simultaneous testing are $25,595.00 for one monitor; $51,190 for two, S76,785.00 for three. Proposed equipment type is Bruel & Kjaer 4427 Noise Analyzer with RS232C port, along with all accessories (microphones, preamps, cables, etc.). This noise level analyzer is the best for our use; Bruel and Kjaer manufacture the most reliable equipment and have many solid years experience and high reputation backing them; calibration is perfo~-med in Anaheim with %oaner equfpment available should repair be necessary. III. Staff Costs Estimating staff cost is difficult since many levels of staff will be working on the project. I anticipate an equivalent of 18 weeks staff time, minimum. Using the top salary cu~-~-ently paid in the noise abatement office yields a cost of $14,580.00. Support costs are not included (typing, etc.) Additional costs not included are possible overtime costs to maintain cu~-~-ent workload status, up to $22,000.00. Management decisions regarding existing' workload vs. measurement program priorities and costs must be made. IV. Other Miscellaneous'QQ~t~ The total estimated cost shown below also delineates a 10% "cushion" for unexpected costs, such as equipment delay/failure, staff time, as well as overhead costs (clerical, mileage, etc.). TOTAL ESTIMATED COSTS: Extra Help: $ 28,368.00 $ 28,368.00 Equipment: 51,190.00 to 76,785.00 Staff: 14,580.00 to 36,580.00 Overhead: 9,412.00 to 14.173.00 TOTAL: $103,550.00 to $155,906.00 TUSTIN NOISE MEASUREMENT PAGE 5 OF 5' Please indicate if this proposed test procedure is consistent with what you had envisioned: Acceptable Procedure: Please revise as noted above: Let's Discuss: ~ .~ cc: Christine Edwards Jan Mittermeier Alan Murphy F.

Representative project ex- posure includes: -- Traffic Noise Studies. Assessing the impact' of traffic noise on numerous proposed residential and commercial projects ad- jacent to major arterials. Also, analyses have been per- formed leading to recommendations for noise barriers along the Route 5, 60, and 605 freeways pursuant to local and FHWA standards. Have completed the noise study for tKe San Joaquin Hills Transportation Corridor, a proposed 14-mile freeway in the County of Orange, California. Each of these studies has required extensive use of the FHWA Traffic Noise Prediction Model. -- Noise Elements. Noise Elements of th~ General Plan have been prepared for several municipalities in the Southern Califor- nia area. Each study involved identifying and measuring the noise producing elements within the City's borders, analyzing the impact of the existing and projected noise environment of the citizens, and, finally, recommending policies by which excessive noise might be reduced to acceptable.levels. -- Airport and Heliport Noi-se Studies. Numerous studies have been prepared to assess the impact of aircraft and helicopter noise on residential and commercial prop-erties in the vicinity of both private and military airfields and heliports. Such studies have involved extensive measurements of aircraft activity, including ground run-up and hovering operations. They have also involved a thorough analysis of the Air Force's AICUZ reports and AMRL data. -- Room Acoustics and Building Isolation. Studies have been performed for both existing and proposed residential and com- mercial projects to ensure compliance with local, state, and federal interior noise standards. In addition, these studies have addressed the problem of inter-office noise control in commercial projects as well as inter-unit noise control in multifamily projects. Typical noise sources for these ~rojects have included traffic, aircraft, trains, oil and water pumping units, mechanical equipment, speech, and park- ing structures. -- Testing. Numerous sound tests have been performed to assess existing noise environments as well as to determine com- pliance with a variety of local, state and federal standards. Such testing has included field STC and IIC tests per ASTM procedures. Each test involved the use of precision acousti- cal instruments. J. J.

EXPERIENCE Projects: Noise Assessment Studies and Consulting Efforts for Airports in California and Arizona Clients: Cities and Counties as well as major land developers with land use and planning concerns in proximity to airports- Soecific Pro~ects: J. J. VAN HOUTEN & ASSOCIATES, INC., has been the principal con- sultant to the County of Orange relative to the noise contour studies conducted in proximity to the E1 Toro Marine Corps Air Station..In addition, noise contours hav9 been developed fur the master plan studies for the Marine Corps Air Station and Interna- tional Airport in Yuma, Luke and Williams Air Force Bases in Maricopa County, and the Phoenix Litchfield Airport in Goodyear, Arizona. We have prepared land use guidelines and building code amendments as part.of these studies. Each study involved exten- sive on-site noise monitoring and ~he use of the FAA's Integrated Noise Model (INM) for the contour development. In the case of the Litchfield Airport our own airport noise contour program was ~used. Airport Noise Monitorin~ Systems California law requires that major airports monitor the noise of flight operations at community locations in proximity to the facility. J.J. Van Houten and. Associates investigated the noise monitoring needs of Los Angeles International, Torrance Munici- pal, and Long Beach Municipal'as consultants to the airports. A performance specification was written for each airport noise monitoring system as a result of these investigations. In addi- tion, bids were evaluated and contractors were monitored. The systems delivered were evaluated leading to a certification of compliance with State requirements. L~nd Use ComPatibility 'The general plan requirements of cities in California include airport noise studies to identify land use compatibility with respect to noise. In addition to the assignments identified above, our study efforts have included noise assessments or resi- dential and commercial developments in proximity to: Orange County (John Wayne) Airport Fullerton Municipal Airport 4ompOc Municipal Airport March A~r Force Base Norton Air Force Base Vandenberg Air Force Base Santa Monica Airport Bakersfield Airport 1.

J. Van Houten and Associates have obtained noise measurements, performed analysis of existing or proposed helicopter operations, assessed the existing or potential impact and recommended methods of mitigating significant impaots for a number of public use and private heliports. The following provides a brief summary of these consulting assignments: AirsDur Commercial Heliconter Service at Fullerton Municipal Client: City of Fullerton Project Monitor: JaY Jaso, Airport Manager and Barry Eat~n, Environmental Planner Report Date: February 1983~and November 1983 Summary: Airspur proposed to operate between LAX and Fullerton on a sche- dule of about 20 operations from 6:30 a.m. to 10:30 p.m. each day. Specific flights were proposed for service using the Westland 30 Helicopter. The noise assessment of the proposal included measurements at representative residential locations in proximity to the approach and departure flight tracks at Fuller- ton Airport. CH2M-Hill had~ previously examined t.he operations for the LAX portion of the service. The noise exposures and sin- gle event sound levels of the proposed operation were compared to the existing general aviation operations. The single event (SENEL and maximum noise level) and long term measures of noise exposure (CNEL) were found to be insignificant; however, the unique character (blade slap) and peak levels to be experienced at residential locations in the vicinity of the operations were identified as a source of potential annoyance. Subsequent to the study, the City approved the proposal and Air- spur had operated for about 6 months before shutting down due to a problem with the Westland 30. Noise complaints have prevailed and exerted citizen concern has been evidenced. An additional evaluation of alternate flight tracks was made just prior to the discontinuation of the Airspur operations. Helicopter Operations at Torrance Municipal Airport Client: City of Torrance Project Monitor: Monte McElroy, Administrator of Community -Development (213) 618 5928 Report Date: September 1983 Summary: A history of complaints which extended over a 13-year period was identified with helicopter operations on the south pattern of the airport. It was apparent from our examination that "blade slap" and the "visual impact" of the helicopter flyovers on homes in proximity to the south pattern were the primary cause of the com- plaints. Fixed based training operations were primarily responsible for the continuing community concern. A 90-day moratorium was placed on helicopter operations in the south pattern by the City Coun- cil. The operators threatened legal action because of the sub- stantlal restriction caused by the moratorium. Noise measurements were obtained and noise oontour studies were performed for alternative flight tracks. The mitigation methods recommended included the elimination of helicopter training ope- rations on the south patternand the development of a new helipad on the north side o.f the AirPort. Operations have now occurred on this new pad with the primary flight track over commercial/industrial areas. Residential Development Proposed Adjacent to the Anaheim Police Client: Ultrasystems, Inc., Newport Beach Project Monitor: "Frank Elfend 714/863-7000 Report Date: August 1981 Summary: A residential development was proposed.which is directly'~djacent to the police helipad. Noise measurements included flyovers of the Department's Hughes 300C and 500C Helicopters. The assessment of impact identified potential annoyance including sleep interference. The City subsequently rejected the project proposal. Santa Ana-Tustin Community HosDital Helioad in the City of Santa Ana Client: Harnish-Morgan-Causey, Ontario Project Monitor: Jorge R. Garcia 714/9'83-9623 Report Date: December 19-80 Summary: The noise assessment included an evaluation of noise exposures expected to be produced by the Bell 2064 helicopter compared to those of traffic on a major freeway. The primary flight track followed the freeway which is adjacent to the hospital site. The City subsequently approved the helipad permit. DELPHI Project in the City of South~ate . Client: Ultrasystems, Inc. and the City of Southgate PrbJeot Monitor: Cecil Sterling, Ultrasystems Program Manager - (714) 863-7000 Report Date: July 1983 Summary: The City proposes to develop a major commercial complex which will include a major helicopter service and sales center. The complex is to have a public heliport ahd up to eight helipads on buildings within the commercial center. Analysis of various flight tracks and nine different helicopter types was performed by use of-our Helicopter Noise Model (HNM) program. The noise exposure contours developed by use of the program were compared to those developed for traffic omthe arterial system and freeway which is in proximity to the project site. Oueen of the Valley Hosoital Helinad in the City of Covin~ Client: Queen of the Valley Hospital Project'Monitor: James C. Lester, Administrator (213) 962-4011 'Report Date: December 19.81 SummarY: Exterior and interior noise levels at homes in proximity to the proposed helipad were examined by use of our Helicopter Noise Model. Noise measurements included 24-hour evaluations at rearyard locations adjacent to the proposed pad. The City subse- quently issued a permit to operate helicopters on a limited basis. Security Pacific National Bank Helinor$ in the City of Brea Client: City of Brea PrOject Monitor: Thomas M. Combiths, City Planner 714/990-7690 Report Date: July 1981 and December 1983 Summary: Security Pacific National Bank proposes to place a helipad on their new regional processing center in Brea. An EIR was pre- pared by J. J. Van Houten and Associates which focused om-noise, air quality and accident potential. Ndise measurements were ob- tained during demonstration flights of the Bell 2064 Helicopter which will. be used to handle.banking transactions. Contours of the peak single event sound levels were developed for both the primary and secondary flight tracks. After completion of our study and prior to public hearings, the bank withdrew the application. More recently, a new application was filed with fewer flights proposed, restricted hours of opera- tion and modified flight tracks. Additional studies have led to an evaluation of this new proposal. Hu~hes Aircraft Company Helioad in the City of Anaheim Client: Canyon Corporate Center (Builder of a new Hughes office, complex) Project Monitor: Richard Roks 714/752-8977 Summary: The proposed hellpad is to operate in proximity to apartments and a home near the primary flight track. Demonstration flights using a Bell 222A Helicopter were used along with analysis to identify noise exposures and potential impacts. The noise of train movements on a major rail line which is near the residen- tial locations was compared to that expected for the helicopter operations. A focused EIR was prepared. The City subsequently requested a full EIR which is now being prepared by Ultrasystems, Inc.
