Since Stratus appeared to agree during Environmental Review, I hope this was a mere oversight. There is no objection to the zoning change; however, the requested change in FAR (required for increased density) does not go without significant deleterious impact. Drainage from this lot quickly enters the Aquifer as well as Barton Creek. The lot lies above 2 disjointed fault lines and one must consider the fact that surface floodwaters from build out of adjacent areas of Lantana Phase 1 Section 2 resulted in more recent buy out of homes below Oak Park /Oak Acres. Additionally, the applicable Drainage Criterion Manual ( from letter of 2001) does not require lined retention/ detention ponds nor pollution controls over most if not the entire Lantana Phase 1 Section 2 acreage. Increasing the FAR fivefold (from .2 to 1) potentially increases the erosion, pollution and non- dispersed sheet flow on- site capture coming from suddenly taller buildings which is not addressed adequately for site plan stage. Consequently, it seems important that the additional donation of land and restatement of IC should accompany any change in the existing Restrictive Covenant for this site.
