BOARD
Taking Care of our Caves
With all of the recent pool construction, there have been several questions about the karst features in (and under) our neighborhood. Karsts are caves or sinkholes. When set aside for protection, they are called karst preserves. Since the beginning of the Hidden Glen development ten years ago, we have been contracting with the Texas Cave Conservancy to inspect the karst lots and perform maintenance. Texas Cave Conservancy is a nonprofit organization founded in 1994 to protect urban caves, cave life, and aquifers. They recently provided the Board with some additional details regarding our property that we thought would be of interest to residents. There are three named karsts: Tres Amigos Cave, Eclipse Cave, and Dos Ojos Cave. These caves contain mostly insects like centipedes, crickets, worms, spiders, and springtails; however, the Tres Amigos Cave also contains an endangered species: the Bone Cave Harvestman. Texas Cave Conservancy inspects each of the caves monthly to monitor their condition. In addition to performing insect counts, they record the temperature, humidity, and CO2 levels and inspect for any trash, chemicals, or sewage. They also make sure the gates and locks are secure. Since the protected insects would be harmed by insecticides, any fire ant mounds are treated using boiling water. The area around the cave is known as the critical habitat area. Each evening crickets leave the cave to eat, and when they return to the cave, they lay eggs. The other cave species then eat the eggs.

This is why the karst lots exist and why the HOA and Hidden Glen residents are restricted from doing anything that would potentially harm them. This also means that residents should be especially cautious when excavating on their lot, such as when building a pool. There are a number of requirements to meet in order to be compliant with state and federal law, and residents should not just assume their pool builder will take care of everything. These requirements, which include hiring a third party professional engineer to provide a geotechnical report ensuring that karst features will not be harmed during construction, are outlined in the Hidden Glen Declarations Exhibit B. Though the ARC has been waiving the individual lot inspection requirement since we are having monthly inspections done at the neighborhood level by the Texas Cave Conservancy, this does not absolve the homeowner if any cave features are discovered during construction. If they are, construction must be halted immediately and an inspection performed. Texas Cave Conservancy works directly with the State of Texas and the U.S. Fish and Wildlife Service and can perform these inspections or recommend an associate. They will generally try to have someone out the same day, and if the feature is not significant, construction can be allowed to continue. If you would like any additional information, please contact Mike Walsh, President, at tcc-caves@austin.rr.com or 512-249-2283.
