History Restrictive Covenants are legal documents that can establish site development regulations and use limitations for certain properties. Several such Restrictive Covenants have been recorded for certain properties located within the Oak Hill Study Area. The Restrictive Covenant under consideration today includes two such tracts of land which are located in the full purpose zoning jurisdiction, in the Williamson Creek Watershed, and in the Contributing Zone of the Barton Springs Segment of the Edwards Aquifer. However, only the regulations associated with Tract 1 are under discussion at this time. Restrictive Covenants associated with the Oak Hill Study Area frequently lock in older site development regulations that predate current water quality protections for the Barton Springs Zone established by City Code 25-8, Article 13 (Save Our Springs Initiative). These properties could develop under the terms of the restrictive covenant without …
