Vice President Post, Buckley, Schuh & Jernigan, Inc. 8600 N.W. 36th Street Miami, Florida 33166 OF TRANSPORTATIOI RE: General Aviation Aircraft Apron Construction West Side - Marathon Airport FDOT WPI: 6826691 Dear Mr. Todd: KATZ N. MZMrM SECRETARY The following is offered as further clarification of the Department's position in response to your October 4, 1989 letter. The Department has determined that the original apron design is inadequate and does not provide a useful and useable product for the future of Marathon Airport. The primary reason for this statement is the fact the base material was not adequately protected from ground water intrusion. Having construction experience in Monroe County, your engineers should have been aware of the high water table, the nature of the area surrounding this site, and the Department's minimum standard criteria for pavements regarding the base clearance above the design high water elevation. The FAA Airport Drainage Advisory Circular 150/5320-5B, provides guidance in the design and maintenance of airport drainage systems. Not only does the Advisory Circular address applying sound engineering principles, but it also states: "When a high water table does exist, provision should be made for controlling or lowering it - or alternatively raising the pavement grades."(Chapter 1, paragraph le.) It would appear evident that due to the high water table along with the elevation characteristics of this project site, raising the pavement grades would be the alternative. In paragraph 2c the statement is made: " The most dangerous consequence of inadequate drainage systems are saturation of the subgrade and subbase, damage to slopes by erosion, loss of load -bearing capacity of paved surfaces, and excessive ponding of water." Then in paragraph 22 it states: "Poor construction leads to progressive deterioration and endless maintenance and reconstruction problems." Mr. William L. Todd, P.E. October 11, 1989 Page Two If in fact your original design protected the base materials from ground water intrusion, we invite and would appreciate the design criteria and the calculations that show this to be the case. As to the Department's suggestions contained in our September 18, 1989 letter to Captain Tom Brown, they were provided as recommended solutions to Monroe County and should be viewed as such. We feel the design needs to satisfy the future apron expansion to the west and the future connector to the taxiway. The FAA Airport Apron Advisory Circular 150/5335-2, indicates that "apron slopes or grades should be kept to the minimum consistent with local drainage requirements." A 0.2% up to a maximum of 0.5% slope on the apron would be acceptable as long as the concern of water intrusion into the base material is addressed. The location, elevation, and capacity of the French drain system is a decision you will be required to make -once you ultimately decide on a final apron design. The above is a position agreed on by my local staff as well as the engineering staff of the Aviation Office in Tallahassee. Monroe County can rest assured that the Department desires to fund and participate in an amount equal to one-half of the non-federal share of this project providing the final design has both FAA and Department approval. It is suggested that Monroe County should verify the FAA's current position regarding the project design and funding participation. In addition, you are advised that the Joint Participation Agreement between Monroe County and the Department contains at least three (3) provisions that apply in this situation. First is paragraph 2.4, which requires the submission and approval of documents as listed in Exhibit "C", i.e. Plans and Specifications. Second is paragraph 11.00, which addresses the authorization of project Audit and Inspections. Lastly, is paragraph 15.00, which deals directly with the approval of Plans and Specifications. It is felt that in view of the field inspection made by the FAA and Department personnel on June 30, 1989, and the immediate concerns expressed in subsequent correspondence by Mr. Shepardson (FAA) (attached) and Mr. Bivins (FDOT) (attached) the problem with the existing project grades, as being constructed, was cause to go back and review this project design. At that time, it was obvious that sufficient information was not provided to staff to enable them to foresee the possibility of a drainage problem. Had elevations west and north of the project construction area and ground water table data been provided, staff may have identified this potential problem. Mr. William L. Todd, P.E. October 11, 1989 Page Three It is further pointed out that your own Resident Project Representative, Ms. D. L. Moscone, in a June 30, 1989 letter (attached) to Mr. Webster of General Asphalt, identified the elevation problems being encountered on site and stated: "Post Buckley drainage engineers were reviewing the plans and would establish contours that would accommodate the existing field conditions." Undoubtedly, your September 6, 1989 design revision of the apron was accomplished to satisfy this situation. If in fact the original design was adequate, why was the September 6, 1989 design revision made? We feel our actions, in this situation, have only been taken in the best interest of Monroe County, the FAA, the FDOT, and the aviation future of Marathon Airport.

Avn. Aircraft Apron Marathon Airport - Monroe County Dear Mr. Skelly, This letter references the final inspection meeting Phil Sellers and I attended at Key West Airport on June 291989. Those in attendance were: , Len Bivins - FDOT Phil Sellers - FDOT Gordon Shepardson - FAA Pat Rebull - PBS&J Donna Mosconne - PBS&J Art Skelly - EYW Airport Charles Knighton - MTH Airport In the future, it is requested that written notification be provided regarding: important inspection/meeting times, dates, location and meeting agenda. This, ''I thought the meeting was ... at such 'n' such a time...", I feel is inconsiderate, unprofessional, inconvenient,'and costly for`' the condensed business schedules of today. Time ismoney! It was obvious and evident that Gordon, Phil, and I were not satisfied with the condition of -the Key West project. The following discrepancies were noted. The premature sealcoat cracking and separation is unacceptable. Taxiway lights (blue) behind marked parking area should be removed or replaced with red lenses. French drain area ponding adjacent to pavement. Pavement in this area does not appear to meet P-401 standards. Page Two July 5, 1989 Mr. Skelly Multiple "Bird Baths" on ramp and in front of Delta Connection. Sodding replacement for dead sod adjacent to taxiway. Later that afternoon, Gordon and I visited the Marathon Airport to inspect the progress of on -going projects. It was suggested by Charles Knighton that there was a low ' elevation problem involving the G/A ramp project area that could cause water runoff ponding. Gordon and I agreed that there appeared to be a design problem and Pat Rebull should be notified as soon as possible for design verification. I understand that a 2 foot elevation discrepancy in the plans must be corrected. The above project items at Key West and Marathon Airports shall not be eligible for Florida Department of Transportation funding participation until such time the condition/discrepancy is properly corrected, reinspected, and approved jointly by the FAA and the Department. Additionally, I must stress the need for SAFETY on and around the Marathon airport active runway, taxiways and aircraft parking areas. I am not satisfied with the aircraft taxi routes in and around the construction area. Aircraft are forced to taxi off paved taxiways, around barriers and across unimproved areas to reach the runway. I feel that appropriate signage, reconfigured routes, and temporary improvements can provide safe aircraft and construction routes during the Marathon project. While on site, I witnessed a construction truck driving closely (est. 5-10 feet) around a small Cessna, doing a preflight run-up, and then down an active taxiway faster than necessary. Incursions to the active aircraft operations area shall not be expected or tolerated. Please educate the construction personnel regarding liability, operation safety, and provide for violation enforcement. Please advise when corrective action is completed and the projects are ready for reinspection. Page Three July 5, 1989 Mr. Skelly Sincerely, Lenwell J.

PB $13 WHITEHEAD STREET KEY WEST, FLORIDA 33040 305/294-6376 ¢ S MEMORAMDUM JUL 71; TO Royal Webster, General Asphalt FROM: D.L. Moscone, Resident Project Representative WOW DATE: June 30, 1989 SUBJECT: MARATHON AIRPORT "Sealcoat Existing G/A Aircraft Parking Apron - Eastside; Construct New G/A Aircraft Parking Apron - Westside; Construct 200' Blast Pads and Stabilized Safety FAA Aip Proj. No. 3-12-0044-0788 FDOT WPI Proj. No. 6826639, 91, & 50 Engineer's Proj. No. 01.476.51 It was brought to my attention by Charles Knighton that your sub- contractor was having a problem with the grades. An on -site inspection by Mr. Knighton and myself, accompanied by Gordon Shepardson of the FAA and Len Bivins of the FDOT, revealed that in the extreem S.W. corner of the new G/A apron under construction, the finish grade appeared to be approximately lz Ft. lower than the surrounding existing area. This was contrary to that shown on the plans as existing and proposed. Upon investigation, Friday, June 30, 1989, it was discovered that in setting grades for that area, Upper Keys Marine surveyors assumed that a 5.0 Ft. contour was a drafting error and set the grade at 3.0 Ft. This indeed put the finish grade below the existing ground and would have allowed water to flow onto the apron. Post Buckley drainage engineers are currently reviewing the plans and will establish countours that will accomodate the existing field conditions. We would like to remind you that the proper proceedure when you or your subcontractor encounter a problem or discrepancy in the plans or specifications, according to Section 50-01, you are required to notify the Resident Project Representative, representing the Engineer on -site. Changes in field conditions from those that are shown on the plans are not unusual in construction. However, the RPR must assess the nature of the problem and determine the proper course of action. Under no circumstances are assumptions to be made where engineering specifications are established. cc: Ron Gilman, Upper Keys Marine Gordon Shepardson, FAA -Len.
