Hilltop Park at the “Y” in Oak Hill
Austin, Texas
|
This site development project to support three retail pads is located on a 9.66 acre site in
the City of Austin’s full purpose jurisdiction. The site is on the south side of Highway 290
West at the intersection of Highway 71 known as the “Y” in Oak Hill. This was the first project
permitted by the City of Austin under the new Commercial Design Standards and one of the retail
pads features a Starbucks with a 6,500 gallon capacity rainwater collection system that provides
water for the site’s irrigation system. The other two retail pads are not yet constructed, but
each were designed and engineered to include rainwater collection systems that feature a 13,500
gallon rainwater collection tank. When construction of all three retail pads is complete, the
total rainwater collection storage on the site will be 33,500 gallons. The project also required
construction of over 1000 linear feet of 8-inch wastewater line along and within the
US 290 Right-of-Way (ROW).
V&A provided PS&Es (plans, specifications, and estimates), preparation of a Storm Water Pollution Prevention Plan (SWPPP) for Wolfcreek Pass, site plan permit & plat processing, and construction phase services. V&A worked with TxDOT and the City of Austin for design of a temporary and permanent driveway, and closely coordinated with these agencies for driveway closures and traffic control at the signalized intersection. The site grading and water quality design included detention ponds to assure that the pond was sized for the adjacent road, Wolfcreek Pass. A portion of the stormwater runoff from Wolfcreek Pass was captured for alternative water quality treatment by an area inlet and routed to a water quality and detention pond on the neighboring Hilltop Park pond via an 18-inch storm drainage pipe system for compliance with the City of Austin. |
