From: Andy Schwaller Sent: Monday, April 30, 2007 4:33 PM To: Brian Condie Cc: Carolyn Dahlgren; Julie Taylor Subject: Parcel # Airport Brian, With the help of the Assessor's Office, the east part of the airport is Parcel# 2177 134 00 205. Separate hangers then get separate lot numbers. If you view the parcel maps online via Garee website, GIS Dept., Parcel maps, general map 2177, the separate buildings will have a parcel number 2177-134-00-hanger lot number. Rando, Savage, Thomas, and Triplat I believe are different owners. The lot numbers are 001-011. East of this batch of buildings are lot 478,479,480, and 290. West of this complex is lots 433 and 432. It would appear the lease parcel number has nothing to do with the lot parcel number .... darn. I believe for building permit purposes, we can use the 2177 134 00 205 parcel number. I will check with Lisa Wardefon when the lot parcel numbers are assigned. My guess is that these numbers are not assigned until after the building permit is applied for. We will need the correct parcel number for the C.O. Thanks, Andy 5/7/2007 GARFIELD COUNTY BUILDING AND PLANNING 970-945-8212 \ MINIMUM APPLICATION REQUIREMENTS FOR CONSTRUCTION OF COMMERCIAL OR MULTI-FAMILY RESIDENTIAL BUILDINGS Including NEW CONSTRUCTION ADDITIONS ALTERATIONS And MOVED BUILDINGS In order to understand the scope of the work intended under a permit application and expedite the issuance of a permit it is important that complete information be provided. When reviewing a plan and it's discovered that required information has not been provided by the applicant, this will result in the delay of the permit issuance and in proceeding with building construction. The owner or contractor shall be required to provide this information before the plan review can proceed. Other plans that are in line for review may be given attention before the new information may be reviewed after it has been provided to the Building Department. Please review this document to determine if you have enough information to design your project and provide adequate information to facilitate a plan review. Also, please consider using a design professional for assistance in your design and a construction professional for construction of your project.

Andy Schwaller Wednesday, June 27, 2007 Skye Gryphon Hangar Garfield County Airport, East side Engineering Department Review of the proposed grading permit I have reviewed the above-mentioned roadway design plans per Garfield County grading permit requirement. and Appendix J of the 2003 IBC. I have the following comments and recommendations for the permit applicant. 1. General comments 1.1. Maximum fill slopes shall be 3:1 without slope stabilization for erosion control. Install erosion control blankets on all slopes steeper than 3:1 to allow for proper re-vegetation. 1.2. Install, maintain, and monitor all BMP'S per your NPDES permit. Periodic site visits by the county will be conducted to observe their installations. 1.3. Grading plan appears to comply with standards and regulations. If you have any questions or concerns, please do not hesitate to call.

The removal of frozen material from the foundation of an embankment, or from any layer of the embankment, and the replacement with satisfactory material shall be at the expense of the contractor. When embankment is to be placed on hillsides or when new embankment is to be constructed against existing embankments, the existing slopes that are steeper than 6 to 1 when measured at right angle to the roadway shall be continuously benched in not less than 12-inch rises over those areas where it is required as the work is brought up in layers. Benching shall be of sufficient width to permit placing and compacting operations. Each horizontal cut shall begin at the intersection of the ground line and the vertical side of the previous bench. Existing slopes shall also be stepped to prevent any 02200-5 wedging action of the embankment against structures. No direct payment will be made for the material thus cut out nor for its compaction along with the new embankment material. Where an embankment is to be made, all sod and organic material shall be removed and the surface completely broken up by plowing, scarifYing, or stepping to a minimum depth of 8 inches. This area shall be compacted in the same manner as that required for the embankment placed on the area. Embankment Material shall be placed in layers not exceeding 8 inches (loose measurement) and shall be compacted as specified before the next layer is placed. The layers shall be placed approximately parallel to both the proposed profile grade and to the finished roadbed. Effective spreading equipment shall be used on each lift to obtain uniform thickness prior to compacting. Continuous leveling and manipulating will be required during compacting operations. Construction equipment shall be routed uniformly over the entire surface of each layer. Cut compaction shall be performed in all cut sections and under embankments ofless than 18 inches in height to insure having 18 inches of material of the required moisture and density below the top of the finished subgrade. A surface parallel to the pavement shall be temporarily exposed for the full width of the roadway. The exposed material shall be scarified and compacted to a depth of 8 inches to not less than the specified density. No direct payment will be made for the material so handled and compacted. Contractor shall remove all excess excavation material from the site. The disposal of the material will be at the Contractor's expense. The Owner shall have the option to have the excess material dumped elsewhere onsite at no extra cost to the Owner. 3.02 Surface Restoration All existing ground surfaces disturbed or damaged during construction shall be restored to a condition equal to or better than the condition prior to construction. All restoration work shall be considered part of excavation and backfill. All roadways shall be restored to original condition using the same types of material removed. The minimum asphalt pavement replacement section shall consist of3" depth of asphalt pavement and 8" depth of Class 6 aggregate base course material. Gravel roadways shall consist of an 8" depth of Class 6 aggregate base course. The minimum concrete pavement section shall consist of 6" depth of concrete on 6" depth of Class 6 aggregate base course. 3.03 Qualitv Control 02200-6 Compaction testing shall be performed as directed by the Engineer. The Contractor shall assist and fully cooperate with the testing operations. The Contractor shall excavate as directed by the Engineer to allow any necessary testing. The Contractor shall backfill all test excavations in accordance with the specified compaction requirements at the Contractor's own expense. The moisture/density curve shall be developed for the different soil types encountered in accordance with ASTM 0698 or AASHTO T99. The field compaction tests will be performed using a nuclear density method in accordance with ASTM 02922. The frequency of testing shall be a minimum of one density test for each 7,500 square foot of each compacted lift surface area and as directed by the Engineer. If the material placed by the Contractor fails the compaction requirements, the Contractor shall excavate, backfill and recompact all failed areas as directed by the Engineer. All retesting shall be paid for at the Contractor's expense and shall be performed by a soils testing firm approved by the Engineer. Proof rolling with a heavy rubber tired roller will be required as designated on the plans or when ordered by the Engineer. Proof rolling shall be done after specified compaction has been obtained. Areas found to be weak and those areas that failed shall be ripped, scarified, and wetted if necessary and recompacted to the requirements for density and moisture at the Contractor's expense from the Engineer. Comparable heavy rubber tired rolling equipment that does not conform to the above requirements may be used only after written approval has been obtained from the Engineer. PART 4-MEASUREMENT AND PAYMENT 4.01 Basis of Payment Payment for roadway and drainage excavation shall be completely covered by the Lump Sum bid therefore, which price shall be full compensation for the excavating and hauling; placing and forming of embankments; preparation of subgrade; shouldering, rounding slopes, finishing of graded earth roadway, picking up and disposing of pickup rock; and any work noted on the plans or the specifications to be included in the price bid for excavation.

Trees shall not be removed without prior approval of the Engineer unless such removal is specifically shown on the plans. Cleared materials shall be disposed of in areas selected by the Contractor and approved by the Engineer. 3 02 Trench Excavation A. General: The Contractor shall perform all excavation of every description and of whatever substances encountered to the depth indicated on the drawings or specified herein, including any required clearing and grubbing. All excavations shall be made by open cut unless otherwise specified or shown. During excavation, material suitable for backfilling shall be piled in an orderly manner a sufficient distance away from the edges of trenches to avoid overloading the sides of the trench. The Contractor shall excavate in advance of the pipe-laying operation only a sufficient length of trench to assure steady progress in the installation of pipe. In public and private rights-of-way, the amount of open trench permitted shall be in accordance with requirements of the Engineer. B. Existing Conditions 02221-2 Existing Property-All existing property adjacent to the work shall be properly protected from any damage by the Contractor. The Contractor, as determined by the Engineer, shall restore all adjacent property, including vegetation, landscaping and existing improvements disturbed or damaged during the performance of the work to original or better condition. The Contractor shall be liable for any damage to adjacent property and shall be responsible for all cost resulting from repairs. Existing I!tilities-The underground utilities, as noted on the plans, are from available information as established from actual field observations and study of existing records. These utilities are noted for information of Bidders and are believed to be correct; however, the Contractor shall take sole responsibility for damage to any utility line encountered whether or not located on the plans, as well as paying for the cost of fines and/or revenue lost by a utility company resulting from outages. The Contractor shall notifY the utility companies for field locations before the start of construction. No change in the Contract Price will be allowed for deflecting utilities up or down to clear a proposed improvement if such deflection can be accomplished by retrenching the utility within l 0' ofthe proposed improvement. Similarly, no change in the Contract Price will be allowed for supporting utilities along the trench wall when such utilities may remain in essentially their current location. Should the Contractor encounter a utility conflict that required relocation, the Contractor shall inform the Engineer prior to relocating the utility. Once the Owner and Engineer have authorized a change order, the Contractor may begin the utility relocation construction. The Contractor will not be paid for any utility relocation completed prior to the approval of the Engineer. Soils.-The Contractor shall be responsible for examining and managing the soils and ground water conditions encountered during his work within the limits of construction. C. Sheeting and Shoring: The Contractor shall abide by the "Rules and Regulations Governing Excavation Work" set up by the Industrial Commission of Colorado, as well as the Federal Department of Labor, Occupational Safety and Health Administration, Occupational Safety and Health Standards-Excavations. Where trench sheeting is left in place, such sheeting shall not be braced against the pipe, but shall be supported in a manner that will preclude concentrated loads or horizontal thrusts on the pipe. Cross braces installed above the pipe to support sheeting may be removed after pipe embedment has been completed. D. Trench Width: The width of the trench shall be ample to permit the pipe to be laid and jointed properly, and the backfill to be placed and compacted as specified. Trenches shall be of such extra width, when required, as will permit the convenient placing of timber supports, sheeting and bracing and the handling of special units as necessary. 02221-3 In order to prevent superimposed loads on the pipe, the maximum width shall be limited to the pipe outside diameter, plus 16 inches on pipe 33 inches and smaller and to the pipe outside diameter plus 30 inches on pipe 36 inches and larger. This requirement shall apply from the bottom of the pipe to an elevation 12 inches above the top of the pipe. Above this elevation the trench walls may be sloped as required to obtain stable sidewalls. E. Trench A I ignment: Horizontal alignment shall conform to the alignment shown on the plans and to the staking approved by the Engineer. Trench centerline shall not deviate more than six inches ( 6") from a straight line between staked points. Bell holes shall be dug at the proper intervals. F. Rock Excavation: Rock encountered in the trench excavation shall be removed to a minimum depth of 4 inches (4") below the bottom of pipe and replaced with approved earth or aggregate base course material compacted as directed by the Engineer and as required to provide a firm foundation for the pipe. G. Removal ofl!nstahle Materials: Wherever, in excavating the trench, the bottom of the trench exposes peat, clay, quicksand or other materials which, in the opinion of the Engineer, will not provide a satisfactory foundation for the pipe, such material shall be removed to the depth directed by the Engineer and the excavation backfilled to trench grade with aggregate base course placed and compacted in layers not more than 6 inches (6") in loose thickness. H. Over Depth: Trenches shall not be excavated below the depth indicated on the plans or established by the Engineer, except as authorized for special bedding or for removal of unstable material. Any over-excavation shall be backfilled with compacted, approved material as directed by the Engineer at no additional cost to the Owner. I. Blasting: The Contractor shall notify the Engineer at least 24 hours prior to any blasting. All blasting shall be done in accordance with local, county, and state regulations governing this class of work.

Normal conditions--whenever possible, water mains should be at least ten feet horizontally from any sanitary sewer or sewer manhole; the distance should be measured edge-to-edge. b. Unusual conditions--when local conditions prevent a horizontal separation of ten feet, a water main may be closer to a sanitary sewer provided that: (I) It is laid in a separate trench. (2) The elevation ofthe crown of the sewer is at least 18 inches below the invert of the water main. Such separation should be of undisturbed or compacted earth. (3) Where this vertical separation cannot be obtained, the sewer should be constructed of materials and with joints that are equivalent to water main standards of construction. 2. Crossings a. Normal conditions--whenever possible, water mains crossing over house sewers, or sanitary sewers should be laid to provide a separation of at least 18 inches between the invert of the pressure water main and the crown ofthe sewer. b. Unusual conditions--when local conditions prevent a vertical separation as described above, the following construction should be used: 02722 - 7 (1) Sewer passing over or less than 18 inches under water mains should be constructed or modified using one of the following methods: (a) One length of pipe at least 18 feet long centered over or under the water main. Joints between the sewer pipe and the special pipe should be encased in a concrete collar at least 6 inches thick and extending at least 6 inches either side ofthe joint. (2) Water mains passing under sewers should, in addition, be protected by providing: (a) A vertical separation of at least 18 inches between the invert of the sewer and the crown of the water main. (b) Adequate structural support for the sewer to prevent excessive deflection of joints and settling on and breaking the water mains. F. Sanitary Sewer Services: Connection to sewer main shall be as shown on the drawings with fittings manufactured to be compatible with the type of pipe used for the sewer main. Backfill under service line shall be well compacted to support the service line and to prevent earth settlement causing the transmission of excessive earth loading to the crown of the main pipe via the service line. Bends will not be allowed in sewer services without the approval of the Engineer and the local authority having jurisdiction. G. Sanitary Sewer Sub-Drains: Where it becomes necessary to drain high ground water along the sewer line, tile subdrains or gravel subdrains shall be provided for sewer sections called for on the drawings or designated by the Engineer. Unless otherwise designated, the minimum size tile subdrain shall be 4 inches and shall consist of perforated polyvinyl chloride (PVC) pipe. The pipe used shall be capable of withstanding maximum trench loads. Where open end joints are pro- vided, the joints shall have the top half covered with construction felt paper to prevent silt filling the drain. The tile subdrain shall be completely bedded in select granular bedding material of 3/4 inch dimension as shown on the detail. 02722 - 8 Where called for, gravel subdrain shall consist of 3/4 granular material only. Unless otherwise designated, the gravel subdrain shall consist of a layer of granu- lar material, a minimum of 6 inches thick below the sanitary sewer. Where called for, the granular material shall be covered with a minimum 6 mil thick polyethylene ("Vis Queen") sheet or approved filter fabric to prevent silting of the subdrain. In all cases, a positive outfall shall be provided for the subdrain with an animal screen on the outlet. 3.02 Manhole Construction A. Standard Manholes: Manholes shall be constructed as detailed and at the location indicated on the drawings and established by the Engineer. The invert channels shall be smooth and semicircular in shape conforming to the inside of the adjacent sewer section. Changes in direction of flow shall be made with a smooth curve passing through the center of the manhole base. The manhole shall be constructed in such a manner that the center of the manhole will coincide with the intersection of the projected centerlines of the inlet and outlet pipes. Changes in size and grade of the channels shall be made gradually and evenly. The floor of the manhole outside the channels shall be smooth and shall slope upward from the spring line of the pipe to the wall of the manhole at not less than one inch (1 ")per foot, nor more than two inches (2") per foot. The invert and manhole bottom shall normally be cast in place concrete. Precast manhole bottoms will not be permitted. B. Manholes With Outside Drop: Drop manholes shall be constructed essentially in the same manner as specified for standard manholes, and all applicable require- ments for manholes shall be adhered to. The outside drop shall be constructed where the difference between the incoming and outgoing invert is greater than 18 inches. The entering pipe (outside drop) shall be carefully placed, aligned, and supported until the backfill around it has been placed and consolidated. The con- crete encasement around the entering pipe shall be formed and shall be anchored to the manhole at 24" on center for drops over 4 feet high. The outside drop shall be constructed according to the detail on the drawings. C. Manhole Couplings for PVC Sewer: To allow for expansion and contraction of the PVC sewer at the interface of the manhole structure, special manhole cou- plings with rubber gaskets (equal to the type manufactured by Johns-Manville) shall be grouted into the manhole. 02722 - 9 In lieu ofthe special coupling, a rubber "0" ring may be stretched over the PVC sewer and grouted in place at the centerline of the manhole wall. The rubber gasket or "0" ring shall be used to prevent infiltration of ground water at the manhole. D. Subgrade Preparation: The subgrade beneath manholes shall be adequate to support the manhole and any superimposed and highway loads transmitted by the manhole. Where the sub grade does not have adequate bearing strength, the foundation for the manhole shall be overexcavated and filled with acceptable granular base to a depth designated by the Engineer. Where rock is encountered it shall be removed to a depth to accommodate the manhole base and a minimum of 2 inches aggregate base course shall be placed on the rock prior to pouring the manhole base. E. Backfill Around Manholes: Backfill around manholes shall be evenly placed and tamped to provide 95% maximum soil density. Backfill materials shall be suitable excavated trench material or aggregate base course material as designated by the Engineer. Care shall be taken in backfilling near the sewer pipe connection to the manhole in order to prevent shearing of the pipe at the manhole wall. F. Cleanouts: Cleanouts, where called for on the drawings, shall be constructed of the same basic material as the sewer line proper. A wye fitting of the appropriate size shall be used at the intersection of the sewer line. A tight fitting cap shall be provided on the cleanout at the ground surface. The backfill around the riser shall be tamped to prevent any displacement of the riser. Unless otherwise specified, the cleanout shall be constructed according to the Standard Detail on the drawings. 3.03 Testing and Infiltration The Contractor shall cooperate with the Engineer and the Owner in the performance of testing the sewer system for leakage and/or infiltration on any sections of the sewer chosen by the Engineer, either before or after backfilling, as directed. The Contractor shall provide such temporary dams, plugs, gages, and/or weirs, in designated manholes, and the separate disposal of flow from pipe or trench upstream from the section being tested as directed by the Engineer. A. Infiltration Testing: The total seepage and infiltration of ground water for PVC sewer as determined by tests shall not exceed a rate of 100 gallons per day, per mile, per inch diameter of pipe. If the performed test results indicate that seepage 02722 -10 and/or infiltration exceed the specified amount, the Contractor shall, at his own expense, make all corrections and retest to the satisfaction of the Engineer. Any one individual section may exceed the allowable rate by one and one-half times if the total length between manholes does not exceed the above described seepage and infiltration rate. The program oftesting shall be determined by the Engineer. All testing shall be in accordance with the required standards and procedures. B. Leakage Test: When required by the Engineer, sewer lines shall be tested using a low pressure air test. Only after the sanitary sewers, including appurtenances and sanitary laterals have been installed, backfilled and cleaned, shall the Contractor proceed with an air test on the installed facilities. 1. Low Pressure Air Test Procedures-The section of sewer line to be tested should be flushed and cleaned prior to conducting the low pressure air test. This serves to clean out any debris, wet the pipe, and produce more consistent results. Isolate the section of sewer line to be tested by means of inflatable stopper or other suitable test plugs. One of the plugs should have an inlet tap, or other provision for connecting a hose to a portable air control source. If the test section is below the ground water level, determine the height of the ground water above the spring line of the pipe at each end of the test section and compute the average. For every foot of ground water above the pipe spring line, increase the gage test pressure by 0.43 pounds per square inch. Connect the air hose to the inlet tap and a portable air control source. The air equipment should consist of necessary valves and pressure gages to control the rate at which air flows into the test section and to en- able monitoring of the air pressure within the test section. Also, the testing apparatus should be equipped with a pressure relief device to avoid the possibility of loading the test section with the full capacity of the compressor. Add air slowly to the test section until the pressure inside the pipe is raised to 4.0 psig greater than the average back pressure of any ground water that may be over the pipe. After a pressure of 4.0 psig is obtained, regulate the air supply so that the pressure is maintained between 3.5 and 4.0 psig (above the average ground water back pressure) for a period of two minutes. This allows the air temperature to stabilize in equilibrium with the temperature of the pipe walls. The pressure will normally drop slightly until temperature equilibrium is obtained. 02722 -11 Determine the rate of air loss by the time/pressure drop method. After the two minute air stabilization period, the air supply is disconnected and the test pressure allowed to decrease to 3.5 psi g. The time required for the test pressure to drop from 3.5 psig to 2.5 psig is determined by means of a stopwatch and this time interval is then compared to the required time in the following table to determine if the rate of air loss is within the allowable time limit. If the time is equal to or greater than the times indicated in the table, the pipe line shall be deemed acceptable. Pipe Size (in.) 8 10 12 Time 5 min. 6 sec. 6 min. 22 sec. 7 min. 39 sec. Upon completion of the test, open the bleeder valve to allow air to escape. Plugs should not be removed until all air pressure in the test section has been released. During this time, no one should be allowed in the trench or manhole while the pipe is being decompressed. C. Manhole Inspection: During the construction of the manholes, the Contractor shall, in accordance with good practice, insure that no earth, sand, rocks or other foreign material exists on the joint surfaces during assembly of the section. The Engineer shall check each manhole to determine whether the manhole fulfills the requirements of the drawings and specifications. 1. Visual Examination-The Engineer shall visually check each manhole, both exterior and interior, for flaws, cracks, holes, or other inadequacies which might affect the operation or watertight integrity of the manhole. Should any inadequacies be found, the Contractor, at his own expense, shall make any repairs deemed necessary by the Engineer. 2. Leakage Test-All manholes shall be tested for leakage and all tests shall be witnessed by the Engineer. The leakage test shall be conducted prior to backfilling around the manhole and shall be carried out in the following marmer: a. All lines leading into or out of the manhole shall be tightly plugged. b. The manhole shall be filled with water to a level at least one foot above the uppermost joint. The water shall be allowed to stand for two hours to allow for normal water absorption into the manhole material. At the end of the two-hour stabilization period, if the 02722 -12 water level in the manhole has dropped below the top ring joint, additional water will be added to bring the level above the joint as before. Any visible external leakage noted within a one-hour test period shall constitute failure, and the Contractor, at his own expense, shall repair the manhole and retest until satisfactory tightness is obtained. 3. Vacuum Test. This test method covers procedures for testing pre-cast concrete manhole sections when using the vacuum test method to demonstrate the integrity of the installed materials and the construction procedures. This test method is used for testing concrete manhole sections utilizing mortar, mastic, or gasketed joints. The final test shall be conducted after the concrete manholes are backfilled. Preliminary manhole testing may be conducted by the contractor prior to backfill to determine manhole condition. a. All lift holes and any pipes entering the manhole are to be plugged. A vacuum will be drawn and the vacuum drop over a specified time period used to determine the acceptability of the manhole. b. A vacuum of 10 in. of mercury shall be drawn on the manhole, then the valve on the vacuum line of the test head closed, and the vacuum pumps shut off The time shall be measured for the vacuum to drop to 9 in. of mercury. The manhole shall pass if the time for the vacuum reading to drop from 10 in. of mercury to 9 in. of mercury meets or exceeds the values indicated in Table I. If the manhole fails the initial test, necessary repairs shall be made by an approved method. The manhole shall then be retested until a satisfactory test is obtained. TABLE 1 Manhole Diameter Time (min.) 0-48 inches 49-60 inches 61-72 inches 3.04 Alignment and Grade Test 60 sees 75 sees 90 sees 02722 -13 Sewer pipelines will be checked by the Engineer to determine whether any displacement of the pipe has occurred after the trench has been bedded to an elevation 16 inches above the pipe and tamped as specified. Ifthe interior of the pipeline shows poor alignment, displaced pipe, earth and other debris in the pipe, or any defects, the defects determined by the Engineer shall be remedied by the Contractor at his own expense. Tests will be repeated after completion of backfilling. 3.05 Cleanup Upon completion of the installation of the sanitary sewer and appurtenant structures and any other work incidental thereto, the Contractor shall remove from the project all equipment, surplus construction materials and debris of any type resulting from the work and shall leave the area in as good or better condition as prior to construction.
