BE IT ORDAINED BY THE CITY COUNCIL OF THE CITY OF CORPUS CHRISTI, SECTION 1. That the City Manager be, and he is hereby, authorized and directed to accept the proposal of Tracor Corporation to provide sound studies at Corpus Christi International Airport, applicable to Project No. 245- 68 -16, a copy of said proposal, marked Exhibit "A ", being attached here- to and made a part hereof. SECTION 2. There is hereby appropriated the sum of $12,200 out of the No. 245 Airport Bond Fund, applicable to Project No. 245- 68 -16. SECTION 3. The necessity to accept the proposal aforesaid and to J appropriate the sum hereinabove set out at the earliest possible date so that sound studies may commence, creates a public emergency and an imperative public necessity requiring the suspension of the Charter rule that no ordinance or resolution shell be passed finally on the date of its introduction but that such ordinance or resolution shall be read at three several meetings of the City Council, and the Mayor having declared such emergency and necessity to exist, and having requested the suspension of the Charter rule and that this ordinance be passed finally on the date of its introduction and take effect and be in full force and effect from and after its passage, IT IS ACCORDINGLY SO ORDAINED, this the ay of September, 1973.

OF. Mr. James Lontos N ELIGIDEF1IK'S' Director of Engineering Services `��,, SERVICES City of Corpus Christi ii Post Office Box 9277 ��9Z /Z 9' y Corpus Christi, Texas 78408 Dear Mr. Lontos: Thank you for the time which you and Mr. Smith spent with me earlier this week discussing a noise study for Corpus Christi International Airport. We have subsequently reviewed various kinds of information regarding the airport and its future development. On the basis of this preliminary examination, we are pleased to submit the following proposal for a noise study which we feel will be most useful for land use planning and control purposes. The City of Corpus Christi, in taking into consideration the noise exposure around the airport before sensitive development has occurred, sold be able to avoid what for many cities has become a re problem. Tracor proposes to perform noise measurements around the airport which, together with air traffic information aftained from local authorities, will be used to compute contours of equal noise exposure around Corpus Christi Internatimnal Airport. These contours will be in terms of Noise Exposnre Forecast (NEF) values, which is the most widely accepted andimsed airport noise descriptor in the USA. When superimposed upon a map of the area, these geographical contours provide a ready assess- ment of compatible land use potential at any tract or point in the vicinity'of the airport. NEF contour sets will be prepared for the following three stages in the development of the airport: 1) Existing airport configuration anD traffic 2) Airport following addition of new 17/35 and 13/31 runways, with projected future traffic 3) Airport following further addition: of another 13/31 ILS runway, with projected future traffic EXHIP17 Mr. James Lontos 10 September 1973 Page 2 We think that these three conditions will provide an adequate assessment of the noise situation, both present and future. The developed contours will be superimposed upon a montage of U.S. Coast and Geodetic Survey maps (or other suitable maps as directed by City engineers) and supplied in large scale reproducible Mylar form. A separate map and contour set will be provided for each of the three conditions enumerated above. The contours will also be incorporated in reduced size into a formal report. The report will document the basic data from which the NEF computations were made and will contain a complete discussion relating different land uses to the zones bounded by the various contours. From this information it will be possible to determine, for example, those land areas which are compatible with light industrial development from the standpoint of noise. The on -site noise measurements and data collection will require approximately one week. If we are authorized to begin the work shortly, the analyses, reports, and - contours can be completed and submitted in February 1974. Tracor will perform the work outlined above for a firm fixed price.of $12,200. I am enclosing for your information a Tracor Annual Report, biographical data on staff members who may be assigned to the proposed project, and information on some of our previous work in the field of airport noise. In particular, your attention is called to the following recent or current projects: Dynamic Preferential Runway System, Kennedy International Airport, New York -This is a computerized noise abatement runway selection system, installed in 1971 and presently being expanded. Sponsors: Aviation Development Council, FAA, Port Authority of New York and New Jersey. Cost: $50,000 initial, $35,000 expansion. Air ort Noise Monitor S stem San Jose Internationa Airport - This is a community noise monitoring system meeting the require- ments of new state regulations and consisting Mr. James Lontos 10 September 1973 Page 3 of eight monitor stations (expandable to fifteen) and a central processor. It is now being installed. Sponsor: City of j San Jose, California. Cost: $129,498. Noise Studies at Naval Air Stations - This series of studies is to document noise exposure around several facilities in terms of Composite Noise Rating (CNR) contours and is currently near completion. Sponsor: Naval Facilities Engineering Command (Southern Division). Cost: $66,000 plus negotiated increase. Thank you for the opportunity of presenting this proposal. Please do not hesitate to call us if you have any questions. Sincerely your Wm. K.
