Smith Consulting Engineer Route 41,2 Preston, Idaho Subject: McCall Municipal Airport, McCall, Idaho, Project.No. 9-10-036- 702 Dear Mr. Smith: Under date'of December 27, 1956 I wrote -you advising -that we had not completed :he indicated changes on :prints of the Plans for the above project that were discussed during our November meeting in Mr. Moulton's office. The prints of the:Plans have now been mtrked with those changes in- dicated by red crayon and'are being transmitted to you along with your tracings ,of the.plans under separate mailing tube.. You will recall'we discussed the reduding of the two knolls in the North approach to the N/S runway, by side casting, to conform. to the CAA approach standards of 40:1.- ,The 40:1 slope starts 200*.beyond the end of,the runway paving, and at.the same elevation'as the end of the pavement. We have made several studies.of different °lava-. Lions for th.e'grading of. this approach,'trying to find -the most economical construction. There -are alss.enclosed, in the mailing. tube, our computations as to the length and -.gradient og the proposed runway." You will notice that it is.a few feet short -of the Federal length requirement for runway but appears .to he the most 'economical approach to grading the North approach zone. The study. includes sample cross sections of the approach zone when it .is in a cut.sec- tion. This conforms to clearances. in the approach- zone , under,, our Technical Standard Order No. N-18. There.are also attached sheets of the approach zone grades and sections showing the computation for:yardage. The first knoll.would require approximately 15,000 1-ds.-of excava- tion_and the second larger knoll would require approximately _ 61;000 yds. These computations were taken.from the.contours shown. -on your plans, and indicated by red crayon. We are enclosing these Mr. Wendell H. Smith Preston, Idaho -2- January 18, 1956 computation sheets for your information so that you might check and verify the yardage. This is in excess of the amounts discussed dur- ing the meeting in Mr. Moulton's office and is the bare minimum that, I believe, can be considered unless you have additional data on the actual ground, configuration in the North approach zone, After you have checkedthesecomputations, it is suggested that you discuss them with Mr. Roberts and see if he is still interested in request- ing Federal assistance in the proposed development under the above project. If such is the case, it would be appreciated if you would confirm his decision and make the statement to that effect in your letter of transmittal of the corrected Plans. The grade of the North approach involves a considerable amount of excavation and it may be that it would involve too much of the City of McCall's expenditures to undertake in conjunction with the above project. If it is not accomplished during the project, and the pro- ject is still wanted for the paving, then an agreement would have to be made by the City of McCa11 that within a definite poriod of time they would accomplish the grade in the North approach with their own funds. A determination by Mr. Roberts on this item is necessary. The changes recommended on the Master Plan, as discussed at the meet- ing in November, have been indicated by red crayon on the print being returned to you. They show the future phasing out of the short NE/Stiff landing strip and a future building area. The Specifications transmitted in your letter of September 29, 1956 appear in acceptable form with four very minor corrections in sentences. We are retaining the four copies of the Specifications youtransmitted, in this office, until we hear further from you relative to the desires of the City of McCall and the corrected plans. Item No. 1, in your cost estimate for the above project, will need to be revised to reflect the quantities that you arrived at for the grad- ing in the North approach zone. You will notice that the study has been made on you utilizing the present landing strip grade as the final grade of the paving for the starting pads. Sorry that we couldn't have gotten this to you sooner, and would ap- preciate hearing from you relative to this at your earliest convenience. A copy of this letter is being sent to Mayor Roberts for his information Mr. 7ende11 H. Smith January 18, 1956 so that he will be familiar with its contents when you contact him. If we can be of any further help, please contact this office. cc - Arthur 'SRN Roberts, Chairman village Board of Trustees McCall, Idaho Yours very truly, Kenneth S. Ferry District Airport Engineer :.; waDELL N. •SNHTH ' ENGINEER - Registered Idaho - 117yoning -.Utah Preston, Idaho January 26, 1957 Mayor, Arthur Roberts Village of McCall McCall, Idaho , Dear -Art, This letter is in response -to our telephone conversation concerning the increased"cest of the Airport Project. I received Mr. Perry's letter and corrected plans in red pencil. - You will recall by checking the previous cost estimate, that we had the total project cost. set at $23,;099 X0, which included construction costs, land cost, engineering, contingencies -and so forth. • The construction cost. only was estimated.at $17,336.00. The_ design_ at that time involved 18,340 cubic yards of excavation and_ embankment.- This was estimated at .35 per cu. yd. or a total of 6,419.00. This involved the excavation mainly on the two knolls that'had to be lowered in the North approach zone. I believe the question -you wanted answered was the increased - :cost of the latest design`prepared'by the C.A. A. over our previous estimate. .The quantities as nearly'as I can determine from the - revised plans 'mould indicate 15,000- Cu.-Yds: to• be removed from the first knell and 61,000 Cu. Yds. to be removed from the second knoll or.a total of.76,000 Cu* Yds. 76,000 cu..yds. less 18,340 cu. yds. figured -in our original estimate leaves an increase of 57,660 cu. yds. Using the 35/.per ou. yd._ as in the previous estimate; this would cost.an additional $ 20,181.00,for construction. Additional'engineering.and overhead would naturally be added to this. However, assuming that this excavation could be done for .25 per - cu. yd. which would probably be the minimum to expect, the added _ cost_of construction would-be about $14,415.00 Again the engineering and -other contingencies would have to be added to this. ,Mayor ; Arthur Roberts January 26. 1957 - As you have a, copy of Mr.-Perry's letter of January 18, 1957, you will note that he has suggested. that the Village sibn an agree- ment to do- the 61,000 cu. yds. of excavation on their own within- 5 years ifthe project .seems too large to handle at; present. This might be a possibility., I"do not know your feelings in this respect. However, unless you wish to follow out the C.A.A. program, it appears that the Village, State and County, with money they were to provide, might go ahead on their own .and get more. actual„ runway paving than to follow the C.A.A. program. I am not.. prepared to say which: would be the wiser thing to do when looking into the` future. Perhaps you with the Village Board and Nr., Moulton world - know more about the future planning than Iwould. I hope this is the information that you wanted. If I: can be of further help please let me know. . Very truly yours, Wendell H. Smith W146/ws February 2, 1957 - r Mr. Chet Moulton, Director Departeent of Aeronautics State of Idaho - Belle. Idaho Dear Chet s Reference is made to our conversation of last Wednesday, January 50, 1957 at your offioe in regard to Projeot No. 9-10-056- 702 on the MoCall Muni- oipal Airport under which we have hoped to.get loge runway paving done. Enclosed .please find copies of oorrespondenoe whioh will bring you tip to date on th. propene -of the pro jeot. As you know, - the planning for this. job has been going on for a long time and it seems very diffioul.t to get - anything definite net up. As indicated in Mr. Perry's letter, the ,Village of McCall is somewhat limited in.funds and no it is mammary for us to be able to justify the commitments we enter in to. To -clarify our position, I should like to list a ntuber of points which will have -to influence our deoision:to go along with this CA.A,Project or to forget it and go ahead -on our own, We have booms* interested in this Federal Aid Project so as to asaure an open approach to the strip and so as to start, at least, an orderly program of runway stabilisation. We have, 1 suppose, when we first vent into a program involving the Federal Government, agreed :to going along with CAA epecifiowtions and requirements. Anyamy, to thisand we have, over the past few years, been busy in the acquisition of band to proteot the ap- proaches to the strip, the clearing of this land to improve the glide angle, seeding the runways in -an effort to stabilise then, tensing the field, improving the drainage struoth es and numerous other maintenance and improvement operations designed to bring the field more in to con. fortuity with CAA requirements.: We believe, however, that some judgment must be used in bringing aboutthis conformity. it is irery. difrioult for us as & Village Board .of Trustees to sell our oom$unity, even if most of the bill is to be paid by the Federal Government, on the proposition of . removing eight or ten feet from a hill which is almost three eighths of a mile from the end of the runway, for an operation which la at present, and for the formable future will be very probably, a daylight, seasonal one. In feat, in our land clearing operation of last fell on the approach sane north of the airport we ran into some oriticisu of our activity as being a waste of tam mum and this from people who are local pilots but also tampsyers. Ws, as a Min* Board, are very muoh in favor of continuing to improve the Meall Municipal Airport and have not yet come to regret the. 000perative effort that b it it. owl be ale c,.however, and provide facilities and ••'!'! ,tom t �... :nlsury- and as they ova, be finanood, Chet Moulton February 2, 1987 Boise, Idaho Specifically, we de not object to the leveling of the first small knoll -at the end of the runway, We do object to moving the Per, larger bill at -this time. Mr Ferry suggests,. as on alternative, that. the Village of Meall agree to aoCapplish, this work- in the near future at local **penes, fie, on • the otheir ' hand, would like to set thin up on a future program basis, her far in the _future► depending onwhen, if ever, the Malanl Municipal Airport. .ii lighted and is kept open on *year around airport depending to sane exs tent on instueeat opsratione bite could and would be glad to agree to this kind of a :program, Unto/ we, as a Village Board, are directed by the people who place us in *Moss it is Very difficult for us to agree to something whioh ere ain't 4.11 to the people and x personally am sure that. this earth moVing•program can not be, sold. This is'a statement ()four feelings in the matter of the proposed Frojeot, If something oan -be worked out along the lines we 'suggest, was will be Very happy, If not, I ate afraid that we will have to forget Federal Aid on the Airport for the present at least. .
