Staff briefs council on proposed PUD at 606½ East Riverside Drive; environmental measures and height waiver flagged

Joy Harden of the Planning Department briefed the Austin City Council on a pre‑application development assessment for a proposed planned unit development (PUD) at 606½ East Riverside Drive during the work session at Austin City Hall.

Harden said the site is about 1.75 acres, currently developed with a single‑story commercial building and surface parking, and sits within the South Central Waterfront Vision Framework Plan and the Greater South River City neighborhood plan. The applicant proposes PUD and P zoning for a mixed‑use development with roughly 200 residential units and about 208,000 square feet of retail/restaurant space, and requests 22 code modifications including an increased maximum building height beyond the waterfront overlay standard.

Why it matters: the site lies inside an urban watershed and adjacent to the Austin light rail alignment, and the applicant’s requested entitlements would require council consideration of tradeoffs between added density/height and environmental safeguards.

Key details from staff briefing

Harden said the site’s baseline zoning (L district) allows up to 200 feet but that the waterfront overlay limits height to 45 feet; the applicant is requesting a higher maximum (recorded in the assessment as 510 feet). In exchange, staff said the applicant proposes multiple “superiority” items intended to mitigate environmental impacts, including restoring roughly 6,000–10,000 square feet within the critical water quality zone to floodplain forest and wetland planting, providing on‑site water quality treatment where none exists today, and conveying and treating runoff from about 0.5 acres of Riverside Drive that currently drains into a local creek.

Procedural context and review

Harden described the development assessment as a code‑required pre‑application step intended to surface staff and commission comments before a formal PUD submission. She said the assessment compiles feedback from multiple city departments; following an application the project will go through formal review, including environmental commission, planning commission and a final council public hearing.

Council questions and staff reflection on process

Councilmembers asked technical and procedural questions. Councilmember Marbella asked about the boardwalk and pedestrian connections; Harden said the applicant is coordinating with Parks and Recreation and other departments. Councilmember Alter raised concerns about the length and cost of the pre‑application development assessment and asked whether the city could instead surface the same review during the formal PUD review. Harden said she believed a consolidated, early review during the standard PUD process could reduce duplication and shorten timelines, but noted that the development assessment is currently required by code and is intended to gather council input before a formal application.

Flooding and environmental review

Councilmember Madietchen and others asked about flooding and how the applicant’s superiority items respond to public concerns. Harden said the applicant has worked with Watershed staff and that the assessment and subsequent environmental commission reviews will address flooding, water quality and green infrastructure measures; she noted that additional environmental commission review is expected before a formal application returns to the council.

No final decisions or votes

No formal action was taken during the work session. Harden reminded council that after the assessment the applicant may submit a formal PUD application and that staff comments will be incorporated into the development review process. Councilmembers requested clearer timelines and suggested staff and council consider whether the development assessment procedure could be streamlined.
