The Pine Mountain Lake Aviation Association (PMLAA) welcomes you to our area. Groveland and Pine Mountain Lake are shared by people with different interests: flying, boating, swimming, fishing, hiking, golfing or just relaxing and enjoying. The Pine Mountain Lake Aviation Association has adopted a Good-Neighbor-Policy and requests that resident and visitor aircraft comply with the noise abatement procedures of the Tuolumne County Airports Department.

Craig L. Pedro, Tuolumne County Administrator, in his letter dated November 13, 2009 reminds all the pilots about the noise sensitive areas near Pine Mountain Lake and Columbia airport. Please familiarize yourself with this page for E45 - Pine Mountain Lake (Groveland) Airport, with the Columbia Airport noise abatement procedure, and also with:

Airport Noise Abatement Procedures

By using your aircraft's quietest departure techniques and following the guidelines and procedures below, we can reduce the noise impact on our neighbors.

Safety always supersedes noise abatement and
 the pilot in command always has the final authority (FAR 91.3).

Please Use Common Sense and be Considerate to Airport Neighbors

  • Use left pattern for runway 9 and right pattern for runway 27.
  • Pattern altitude is 3930 ft. MSL.
  • Reduce propeller RPM as soon as safe and practical**
  • Avoid flying over the lake, the golf course and the homes in noise sensitive areas depicted below.
  • Be careful of numerous deer in the vicinity, especially at and after sunset.
  • These procedures apply to VFR operations only, for IFR operations see the appropriate FAA Instrument Approach and Departure procedures.

**Most aircraft noise is generated by propeller tip noise.  This is especially true when propeller tip speeds approach supersonic speeds.  Even a small reduction of 100 to 200 RPM can produce a significant decrease in noise levels. You can learn more about this at

Noise Sensitive Area

Do NOT Fly over the Lake below 4,550’ MSL.
Do NOT Fly over the Golf Course below 4,800’ MSL

This area is included in the sector delimited by

  • the 160 from (340 to) radial of the airport,
  • and the 260 from (80 to) radial of the airport
  • and 3 SM from the airport.

Suggested VFR Departure Procedures RWY 27

  • From 0  to 159 fly a right traffic pattern to 4000 ft and then proceed on-course
  • From 160 to 259 climb runway heading to 4,800 ft or until west of the golf course and then proceed on-course via left crosswind or fly right traffic until 4,800’ and proceed on course
  • From 260 to 359 fly runway heading until 3,630 ft and then proceed on-course

Suggested VFR Departure Procedures RWY 9

  • From 0 to 159 climb on the runway heading to 3,630 ft and then proceed on-course
  • From 160 to 259 fly a left traffic pattern to 4,800 ft and then proceed on-course
  • From 260 to 360 fly left traffic until on course

Suggested VFR Arrival Procedures RWY 9 and RWY 27

  • From 0 to 159 no arrival restrictions.
  • From SSE (160) to WSW (260) maintain 4800 ft with reduced RPM/power setting until 0.5 miles south of the airport and then enter the traffic pattern.
  • From 260 to 359 no arrival restrictions.

Additional considerations

  • Do not turn crosswind until well past the runway threshold: please respect homeowner's safety concerns by not flying low over their homes
  • While airport residents enjoy airplane noise, repeated low approaches at high power settings can be annoying
