Karst feature definition

Karst feature means an area or surficial geologic feature subject to bedrock dissolution so that it is likely to provide a conduit to groundwater, and may include caves, enlarged fractures, mine features, exposed bedrock surfaces, sinkholes, springs, seeps or swallets.
Karst feature means caves and mesocavernous voids in landforms and subsurface features produced by dissolution of limestone bedrock.
Karst feature means any subsurface cavity that: (a) is greater than six inches across in any direction; (b) is greater than one square foot along any plane; (c) blows air; (d) continually receives water during a rain event; or (e) has water flowing through or Karst Feature Mitigation Plan out of it. means a karst feature mitigation plan contemplated in the RID entitled “Karst Feature Discovery and Mitigation.” Karst Mitigation Delay has the meaning set forth in Section 6.9.3 of this DBA.

Examples of Karst feature in a sentence

  • A Karst Investigation Delay begins on the date DB Contractor notifies TxDOT, in accordance with Section 12.2.5.6 of the Design-Build Specifications, that a Karst Feature contains suitable habitat for endangered karst invertebrates and ends upon the earlier of (a) completion of the presence/absence surveys required under Section 12.2.5.6 of the Design- Build Specifications for such Karst Feature and (b) discovery of any species listed as a Threatened or Endangered Species at the Karst Feature location.

  • If a Karst Investigation Delay exceeds 30 days for a particular Karst Feature, then the risk of such Karst Investigation Delay in excess of 30 days for that Karst Feature shall be borne by TxDOT.

  • Subject to Section 4.6 of the General Conditions and this Section 6.9, DB Contractor shall be entitled to an extension of applicable Completion Deadlines for delays to a Critical Path attributable to performance of presence/absence surveys at a Karst Feature required by Section 12.2.5.6 of the Design-Build Specifications, and the need to work around locations subject to temporary no-work restrictions due to performance of such surveys (“Karst Investigation Delay”).

  • DB Contractor shall bear 100% of the risk of Karst Investigation Delays up to 30 days per individual Karst Feature and up to a cumulative total of 120 days for all Karst Feature locations.

Land-disturbing construction activity includes clearing and grubbing, demolition, excavating, pit trench dewatering, filling and grading activities.
Karst feature means but is not limited to sinkholes, caverns and swallets.
Karst feature means a topography formed by the dissolution of soluble rocks such as limestone, dolomite, or gypsum and includes features such as cracks, fractures, or holes dissolved into the bedrock and which may form a direct conduit to groundwater.
Karst feature means any cave, sinkhole, sinking stream, bluehole, crevice, spring, lost river, karst window or any other geologic feature associated with karst terrain.
Karst feature means but is not limited to sinkholes, caverns and swallets. “Karst feature” means any sinkhole, sinkhole lineament, cave, cavern, swallet, spring, or similar feature found in an area identified as an area of karst geology characterized by the presence of soluble bedrock such as limestone, dolomite, marble or gypsum. Karst features shall include all such features identified in Appendix L of the EIS and any subsequently identified features in areas of karst geology.
