Airport Closure Information

Last updated: Jul 26, 2025
Closure Date

Approximately between the late 1990s and early 2000s. Topographical maps from 1995 clearly show the airstrip, while maps and satellite imagery from the mid-2000s show the completed residential development. The exact date of final flight operations is not publicly recorded.

Reason for Closure

Economic reasons, specifically urban development. The land occupied by the private airfield was redeveloped into a residential housing subdivision known as 'Mountain Lakes Estates'. This is a common fate for private airfields located near growing urban areas, as the land becomes more valuable for real estate than for aviation.

Current Status

The site has been completely and permanently converted into a residential subdivision. The former runway's path is now occupied by a paved road named 'Mountain Lakes Drive' and the surrounding area is filled with single-family homes and properties. No trace of the original airstrip infrastructure remains.

Historical Significance

Mountain Lakes Field was a small, private-use airstrip serving general aviation pilots. It consisted of a single turf or gravel runway aligned approximately north-south. Its operations were limited to light, single-engine aircraft, likely owned by the landowner or local residents. It held no major regional or national significance and did not support commercial, cargo, or military operations. Its primary role was purely for recreational and private flying.

Reopening Prospects

There are no plans or prospects for reopening the airport. The land has been irrevocably re-purposed for residential use, with numerous private homes built directly on and around the former airfield. Reacquiring the land and demolishing the homes to rebuild an airport is not feasible.
