At first glance, Philadelphia and Austin, Texas, don't appear to have much in common. Even at second and third glance they don't have much in common; one is a hardscrabble former industrial city in the northeast, the other a smaller yet bustling southern city known for its music and nightlife.
But like Philadelphia, Austin has a riverfront close to its downtown that frames and shapes the city in significant ways. In fact, the Colorado River runs directly through Austin and forms what locals call the Town Lake Corridor or Lady Bird Lake shoreline - a waterfront that stretches roughly four miles, from Lady Bird Lake on the east to Zilker Park on the west.
The lake is actually a reservoir the City of Austin built in 1960 as a cooling pond for the Holly Street Power Plant. That year, the city constructed Longhorn Dam, which became the lake's eastern boundary; the western end of the "lake" is the Tom Miller Dam, which was built in 1939.
Although the reservoir itself was made for an industrial use, part of the master plan was to create a recreational area in the heart of the city. By the 1970s, an early system of hiking and biking trails was built on the reservoir's shoreline.
So although it has some industrial roots, Austin's waterfront - unlike Philadelphia's - was never a commercial hub, and is neither dotted with ghostly 20th century industrial ruins nor used as an active shipping corridor.
Yet for all its idyllic, pedestrian use - the kind of use urban designers in Philadelphia dream about for the Delaware - lately Austin's waterfront has been awash in competing interests and bureaucratic delays. In recent months, some controversy has surrounded the recommendations of the Waterfront Overlay Task Force, a body convened last year and charged to revise elements of the original 1986 Waterfront Overlay Ordinance, which established rules for development along the river including height limits of 96 feet on all development in the Waterfront Overlay district.
Height limits along Austin's waterfront have been a contentious issue for some time. In a 1999 rewrite of the overlay ordinance, height limits were effectively eliminated - a move conservationists have loudly decried. The current ordinance rewrite, which Austin's City Council recently passed, reinstated the 1986 height limits with exceptions for Planned Use Developments.

However, the task force's recommendations - and even its existence - are making waves, and attempts to rewrite zoning overlays for the city's much-used waterfront are pitting private developers against community and conservationist groups like SaveTownLake.org.
Still, Austin's experience can be instructive in this respect: the reason all this is happening is because, despite the creation of a sweeping waterfront overlay ordinance in 1986, and a rewrite in 1999, the city has still not implemented some of the key "action priorities" laid out in the 1985 study.
