Additional Backup Information:
The owner of the property located at 4905 Prock Lane, through their agent David Petcosky, has filed an application for a residential building permit (permit application number 2024-084851 PR) for the proposed development of a duplex on a vacant lot. The proposed development is to construct a two story 6,502 square foot building that contains two dwelling units.
A single-family building existed on this lot until 2024 when it was demolished. Adding a duplex on this property increases the number of dwelling units within the floodplain that are at flood risk.
The entire property is located within the 100-year floodplain of Tannehill Branch Creek.
The owner seeks variances to the City of Austin’s floodplain management regulations to: 1) encroach on the 100-year floodplain with the proposed building; and 2) not provide normal access from the building to an area that is a minimum of one-foot above the design flood elevation (100-year floodplain); and 3) exclude the proposed building footprint from the required drainage easement.
Austin Watershed Protection recommends denial of this variance request due to life safety concerns.
