4 Preliminary Alternatives Alternative 1 – Do-Nothing (Maintain 4,800’ length)Alternative 2 – Extend runway to 6,360’Alternative 3 – Extend runway to 6,860’
5 Final Alternatives Alternative 1 – Do-Nothing (Maintain 4,800’ length) Alternative 4 – Extend to 5,650’ (adds 850’ fully usable length and does not relocate N. 75th Street)Note: Alternatives 2 and 3 were eliminated from further consideration by vote of the Airport Advisory Board. Alternative 4 was added following the first public information meeting and third regular meeting of the AAB.
7 Alternative 4: Extend Runway (adds 850’ fully usable length)
8 Evaluation Criteria Safety Ability to meet aviation needs Airspace Surface AccessEnvironmental FactorsAvailability of UtilitiesLand RequirementsCostsCommunity CompatibilityLocal Acceptability
9 Evaluation ResultsSafety: Alternative 1 does not address the needs of larger aircraft types that currently use the airport e.g., Cessna Citation Bravo, KingAir 90, etc. Alternative 4 provides additional distance for take-off, landing, and emergency operations.
11 Evaluation ResultsMeet Aviation Needs: Alternative 1 (current length 4,800’) meets the needs of 75 percent of small airplanes with <10 passenger seats. Alternative 4 provides (length of 5,650’) nearly 90 percent of the runway length recommended for these small airplanes.
14 Evaluation ResultsAirspace: Alternative 1 does not alter existing airspace requirements. The change imposed by Alternative 4 is to small to cause any major disadvantage.
15 Airport Influence Area: Do-Nothing and Alternative 4
16 Evaluation ResultsSurface Access: Neither Alternative requires an disruption of the surface access system, notably North 75th Street, in the area of the airport.
17 Evaluation ResultsEnvironmental Factors: Alternative 1 enjoys an advantage because it does not require any development. Alternative 4 would generate construction impacts (dust, etc.) that will need to be mitigated. Alternative 4 will also require land acquisition (approx. 27 acres and relocation of one affected owner. Noise exposure exceeding 65 Ldn would not extend beyond proposed airport land and easements.
18 Evaluation ResultsAvailability of Utilities: The alternatives are considered equal with respect to this criterion. Neither will impose significant new requirements.
19 Evaluation ResultsLand Requirements: Alternative 1 does not require land acquisition. Acquisition of avigation easements would be recommended. Fee simple acquisition of approximately 27 acres and one residence would be recommended under Alternative 4.
20 Evaluation ResultsCosts: Alternative 1 does not require capital expenditures for runway extension. Estimated costs for Alternative 4 are $2.4 million ($2.16 FAA; $120,000 state; and $120,000 local)
21 Evaluation ResultsCommunity Compatibility: Alternative 4 requires no zoning or land use changes and community compatibility impacts are minimal. It requires no zoning or land use changes. Alternative 1 has no additional compatibility effects.
22 Evaluation ResultsLocal Acceptability: Alternative 1 is preferred by opponents of airport expansion. Alternative 4 is a compromise generating less opposition than more ambitious runway extension alternatives.
23 ConclusionsAlternative 1 imposes fewer impacts because it makes no improvements.Alternative 4 addresses aviation safety for airplanes that use the airport now and in the future.Consultant’s and AAB’s recommendation: Alternative 4.

28 Airport Noise Abatement Procedures: Updated in 2002.
29 New Procedures Include: Traffic pattern altitude 6,050 MSL (raised 150 feet)Pilots should climb to at least 500 hundred feet AGL after takeoff before turning crosswind.Pilots are requested to avoid making touch and go landings at the Longmont Municipal Airport before 8AM and after 8 PM.Avoid flying over the city and outlying residential areas as much as possible.
30 Airport Master Plan Summary and Notes: The Airport Master Plan is a planning tool to help guide the future of the airport for all aspects of aviation and community needs. This is a ten-year plan that will be updated again in the future.The projects contained in the Airport Master Plan are unfunded at this time.
31 Airport Master Plan Schedule: Staff and AAB to receive City Council direction on January 7, 2003.Approximately 6 weeks for completion of final draft.Final “Draft” of the Master Plan with the Council chosen options to be presented in March 2003.Anticipate adoption of final Master Plan by Resolution in April 2003.
